Subject: [PATCH 1/7] chore(ai-harness): introduce .ai/ agent harness pilot
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Stand up a team-shared AI agent harness in this repo as the pilot for a
broader internal initiative. The harness is committed, multi-agent, and
reproducible from a fresh clone.

What lands:

- `AGENTS.md` becomes the canonical prose-rules file; `CLAUDE.md` is a
  one-line `@AGENTS.md` shim. Codex, Cursor, Windsurf, VS Code Copilot
  read AGENTS.md natively; Claude Code via the shim.
- `.ai/` directory holds: `LANGUAGE.md` (vocabulary), `plans/` (committed
  historical plans, migrated from `docs/plans/`), `research/` (date-prefixed
  artifacts), `memory/` (team product knowledge — product / architecture
  / stack / lessons / topics / integrations / initiatives), and `skills/`
  (vendored superpowers v5.0.7, MIT, Jesse Vincent).
- `.claude/settings.json` disables the global `superpowers` plugin per
  project so the vendored copy is the single source of truth.
- Symlinks `.claude/skills`, `.agents/skills`, `.cursor/skills` all point
  to `../.ai/skills`, giving Claude Code, Codex (`.agents/skills/` is the
  Codex spec path), and Cursor 2.4+ the same skill set without duplication.
- `.codex/config.toml` is committed with the project's nx-mcp setup.
- Per-package vocabulary cleanup: `apps/cli/AGENTS.md`, `apps/server/AGENTS.md`,
  and `docs/specs/SPEC-013-mintlify-docs-site.md` updated to drop "device
  flow" (the CLI uses an OAuth2 loopback redirect, RFC 8252) and to remove
  references to a non-existent `migrate` CLI command.
- `apps/server/AGENTS.md` corrected to reflect that sessions live in
  Postgres, not Redis (Redis is provisioned for caching/queues but not
  currently a session store).
- `.gitignore` adds `.vercel/`, `*.tsbuildinfo`, the personal local-only
  paths under `.ai/skills/`, and `.claude/settings.local.json`.
- `.prettierignore` excludes vendored `.ai/skills/` and historical
  `.ai/plans/` so bumps and migrated content stay verbatim.

Memory bank shape borrows from Cline's pattern but drops the
solo-developer-state files (`active-context.md`, `progress.md`) that
cause merge conflicts on concurrent PRs. Stable knowledge lives in
single-purpose files; volatile state stays in Jira / `ROADMAP_TASKS.md` /
GitHub Issues.

Out of scope for this pilot: the generic multi-project installer skill
(`/install-dot-ai`-style), an evals suite, hooks for deterministic rule
enforcement, an org-level cross-project memory layer. Those are the
Phase 2 wishlist if and when the harness proves itself in MDCMS.

+## Forbidden
+
+- "Entry" — always use **document**.
+- "Workspace" when referring to **project** — they're different concepts. ("Workspace" is fine when referring to a Bun + Nx package in the monorepo.)
+- "Plugin" when referring to a first-party **module** — modules are first-class. (Third-party concepts that genuinely call themselves plugins, e.g. TipTap plugins, can keep that name.)
+- "Device flow" for the CLI auth handoff — it is a **loopback OAuth flow** (RFC 8252), not RFC 8628 device authorization grant.

+# Memory
+
+Persistent team knowledge about MDCMS — the product, the architecture, the integrations, the major efforts in flight, and the lessons we've already learned. Read this when you need _durable_ knowledge. For _volatile_ state (what someone is working on right now, current sprint, blockers), use Jira / `ROADMAP_TASKS.md` / GitHub Issues — those are the right tools for that, and trying to mirror them here causes merge conflicts on every concurrent PR.

+## Layout

+| [`lessons.md`](lessons.md)           | Append-only dev-time pitfalls                                         | Append on discovery                                      |
+| [`topics/`](topics/)                 | Cross-cutting domain knowledge — auth flow, sync, multi-tenancy, etc. | When a topic stabilizes or changes meaningfully          |

+
+Vocabulary lives at [`../LANGUAGE.md`](../LANGUAGE.md). Architecture decision rationale lives at `docs/adrs/` (canonical product docs). Specs live at `docs/specs/`. Per-package guidance lives at `apps/*/AGENTS.md` and `packages/*/AGENTS.md`.
+
+## How an agent should read this
+
+```
+First-time / onboarding
+  └─ product.md → architecture.md → stack.md → skim topics/ index → skim initiatives/ active
+
+Starting a feature
+  └─ architecture.md (invariants) → topics/ (relevant cross-cutting) → initiatives/ (does this fit something?)
+       → docs/specs/<owning>.md  (canonical scope, NOT in memory/)
+
+Debugging a thing that broke
+  └─ lessons.md (have we seen this?) → topics/ (cross-cutting flow) → integrations/ (external system?)
+
+Wondering why something is the way it is
+  └─ architecture.md (patterns) → docs/adrs/ (decision rationale) → initiatives/ (which effort drove this?)
+```
+
+## How to update
+
+- **product.md / architecture.md / stack.md** — directly, in the PR that changes the underlying reality. Docs, not state. Reviewed in PR.
+- **lessons.md** — append at the bottom on discovery. Lead with the rule, then `Why:` and `How to apply:`.
+- **topics/** — add a new file when a cross-cutting concept stabilizes; update existing files when the flow changes. One topic per file.
+- **integrations/** — add a new file when integrating a new external system; update on config/auth changes.
+- **initiatives/** — create on kickoff, update on milestones, mark `Status: completed` on wrap. One initiative per file (no shared write surface = no merge conflicts).
+
+## Why this shape (and not something more sophisticated)
+
+Two reference systems we considered:
+
+- **Hermes Agent** — minimalist 2-file (MEMORY.md + USER.md, ~3.6KB total), frozen-snapshot system-prompt injection, FTS5 over session history, designed for solo use.
+- **Magic Context** — sophisticated 4-layer SQLite + vector embeddings + 5 access tools, designed for solo use.
+
+Both are user-local. Neither is committed to a team git repo. SQLite databases don't merge cleanly; user-home memory doesn't share with the team.
+
+Our system trades runtime sophistication (no semantic search yet, no auto-injection beyond `@AGENTS.md`) for **team-shareability and version control**. If we later want semantic search, the right move is an MCP server that indexes these markdown files — the files stay the source of truth.
+
+## What this is _not_
+
+- Not a status report (Jira / GitHub Issues).
+- Not a todo list (`ROADMAP_TASKS.md`).
+- Not a spec (`docs/specs/`).
+- Not a changelog (git log + PR descriptions).
+- Not a runbook (operator docs go in package READMEs).
+- Not a personal journal (Hermes-style USER.md belongs in user-home, not the repo).
+
+This is the **shared mental model** the team and its agents maintain about MDCMS.

+# System patterns
+
+Architecture invariants and key technical decisions. Update when one changes.
+
+## Source of truth
+
+- **Database is canonical**, not the filesystem. The server is the only thing that owns truth.
+- The CLI's local files are a working copy. Pull/push reconciles against the server, not vice versa.
+- Schema (content types + fields) lives in the server's schema registry. The local `mdcms.config.ts` is the developer's authoring surface; `schema sync` reconciles it to the registry.
+
+## Module system
+
+- First-party modules live under `packages/modules/<module-id>/`.
+- Each module ships `manifest.ts`, `server/index.ts`, `cli/index.ts`. Some also ship `studio/index.tsx`.
+- The `installedModules` registry in `packages/modules/src/index.ts` is **deterministic and sorted by `manifest.id`**. Don't introduce ordering coupling.
+- Server and CLI each have their own `module-loader.ts`. Both auto-mount at startup.
+- Cross-module dependencies go through declared interfaces in `@mdcms/shared`, never direct imports between module packages.
+
+## Package boundaries (hard rules)
+
+- `@mdcms/shared` exports types, validators, pure utilities. **No runtime side effects, no HTTP, no DB.**
+- `@mdcms/sdk` is read-only. Bearer-token client. **No write methods.**
+- `@mdcms/cli` owns push/pull/sync logic and the loopback OAuth flow.
+- `@mdcms/studio` runs inside the host app's process — embedded React component, not a separate page.
+- `@mdcms/server` is the only thing that talks to the database.
+
+## Conditional exports
+
+Every package uses `@mdcms/source` as a custom condition pointing to TypeScript source for development. `import` and `default` point to `dist/` for production. **Don't break this convention** — dev-time source imports rely on it.
+
+## Validation
+
+- All inputs validated with **Zod 4** at module boundaries.
+- Content schemas use **Standard Schema** for ecosystem interop.
+- No double-validation; once a value is parsed, downstream code trusts the type.
+
+## Tests
+
+- **`*.test.ts`** — unit tests, co-located with source.
+- **`*.contract.test.ts`** — Drizzle schema validated against actual SQL migrations. Catches drift between ORM definitions and migration outputs.
+- **Integration:** `bun run integration` runs Docker health + migration check.
+- **CI gate:** `bun run ci:required`.
+
+## Studio review app
+
+`apps/studio-review` is a maintained internal consumer of Studio + backend contracts, used to keep preview mocks aligned. Whenever a contract changes, update `apps/studio-review` handlers/fixtures/tests in the same commit. Don't let it drift.
+
+## Standalone specs
+
+Files under `docs/specs/` are **standalone canonical product documentation**. No roadmap task IDs, no `ROADMAP_TASKS.md` references, no "this task" language. Spec rationale either stays self-contained or moves to an ADR.
+
+## Multi-tenant boundaries
+
+- **Project** is the isolation unit. Every persistable entity carries `project_id`.
+- **Environment** is a state within a project (e.g. `draft`, `prod`). Reads default to the published environment unless explicit.
+- Tenant scoping is enforced at the route layer — every authenticated request resolves a project context before reaching domain code.

+# Initiatives
+
+A file per major team effort — active and completed. Initiatives are bigger than tasks (which live in Jira / `ROADMAP_TASKS.md`) and longer-running than features. Examples: a multi-quarter platform migration, an open-source release, a customer-driven SLA push.
+
+## File format
+
+`YYYY-MM-DD-kebab-case-name.md` for the start date.
+
+Each file has these sections:
+
+- **Status:** `active` | `completed` | `paused` | `abandoned`

+# Docker stack
+
+## What it is + why
+
+Local infrastructure for development. MDCMS depends on PostgreSQL, Redis, MinIO (S3-compatible object storage), and MailHog (SMTP catch-all for dev email testing). All four run via `docker-compose.yml` at the repo root.
+
+## Configuration
+
+```bash
+docker compose up -d --build         # Bring up the stack
+docker compose down                  # Tear down
+docker compose logs -f <service>     # Tail a service
+```
+
+Services:
+
+- **postgres** — PostgreSQL 16. Used for content, auth, sessions, and audit logs.
+- **redis** — Provisioned for caching, queues, and rate-limiting. Not currently a session store.
+- **minio** — Media uploads (S3-compatible).
+- **mailhog** — Dev-only SMTP capture; web UI at `localhost:8025`.
+
+The server expects this stack on default ports. Ports and credentials live in `docker-compose.yml` and the server's `.env` (local-only).
+
+## How agents interact
+
+Mostly indirectly — agents run server commands that assume the stack is up:
+
+```bash
+bun --cwd apps/server run start    # Server on :4000, expects docker stack up
+bun run integration                 # Runs Docker health + migration check
+```
+
+For a clean re-run during debugging:
+
+```bash
+docker compose down -v && docker compose up -d --build
+```
+
+The `-v` flag drops volumes — useful when starting from a clean DB state, **not safe** if you want to preserve seeded content.
+
+## Failure modes
+
+- **Port conflicts.** If Postgres 5432 or Redis 6379 are already in use locally, `docker compose up` fails. Check with `lsof -i :5432`.
+- **Volume corruption from killed containers.** `docker compose down -v` resets state.
+- **Stale image after dependency upgrades.** `--build` rebuilds; without it, you might run an outdated server image.
+- **MinIO bucket missing.** First-time setup may need explicit bucket creation (`mc mb local/mdcms`); check server logs for `NoSuchBucket`.
+
+## Cross-refs
+
+- Compose file: `docker-compose.yml`
+- Per-package: `apps/server/AGENTS.md`
+- Related: [`../stack.md`](../stack.md) for the broader stack context.

+# GitHub Actions
+
+## What it is + why
+
+CI gates running on push and PR. Defined in `.github/workflows/`. The required gate is `bun run ci:required` — anything that fails this blocks merge.
+
+## Configuration
+
+Workflow files live at `.github/workflows/*.yml`. Each workflow declares triggers (push, pull_request, schedule) and jobs.
+
+## Required gate
+
+`bun run ci:required` runs:
+
+1. `bun run format:check` — Prettier check.
+2. `bun run check` — Build + typecheck combined.
+3. `bun run unit` — Unit tests via `bun test` orchestrated by Nx.
+4. `bun run integration` — Docker health + migration check.
+
+A pre-push git hook also runs this locally to catch failures before the push reaches CI.
+
+## How agents interact
+
+- Read workflow files to understand what CI runs.
+- Don't push if `ci:required` is failing locally — the pre-push hook will block, and even if bypassed, the PR will fail.
+- Use `gh pr checks` or `gh run list` to inspect a PR's CI status without leaving the terminal.
+
+## Failure modes
+
+- **Format check failing** — almost always a missed `bun run format` before commit. Run it, commit the diff.
+- **Typecheck failing on a PR but not locally** — usually means dependencies got out of sync; `bun install` and re-run.
+- **Integration step timing out** — Docker stack startup is slow on cold caches. Local runs may pass while CI fails. Inspect the run logs for the specific service that didn't come up.
+- **Pre-push hook blocked.** Don't bypass it (`--no-verify`) without understanding why it failed; usually it's surfacing a real issue.

+# Nx MCP
+
+## What it is + why
+
+`nx-mcp` is an MCP server that exposes Nx workspace operations (project graph, target running, generator listing) to AI agents. It lets agents reason about the monorepo's structure and run Nx commands without invoking the Nx CLI directly.
+
+## Configuration
+
+Defined in `.codex/config.toml` (committed):
+
+```toml
+[mcp_servers.nx-mcp]
+command = "npx"
+args = [ "nx-mcp@latest", "--minimal" ]
+```
+
+The `--minimal` flag scopes the server to lightweight operations (project-graph reads) without enabling heavier features.
+
+## How agents interact
+
+Codex CLI loads the MCP server on session start. Tools exposed include workspace project listing, target running, and generator listing.
+
+Other agent harnesses (Claude Code, Cursor) load MCP servers from their own per-tool configuration files outside the repo.
+
+## Failure modes
+
+- **`npx nx-mcp@latest` fails to install** — usually a network issue. Run `npx nx-mcp@latest --help` manually to surface the underlying error.
+
+## Cross-refs
+

+# Project brief
+
+## What MDCMS is
+
+A collaborative CMS built around Markdown/MDX for React-based frameworks. The database is the source of truth (not the filesystem). Editors work in a browser-based Studio, developers work with local `.md`/`.mdx` files synced via CLI, and consumer applications fetch via SDK or REST. All three surfaces share the same data layer, validation, permissions, and version history.
+
+## Why it exists
+
+Existing headless CMSes force one of two compromises: filesystem-based tools (Contentlayer, MDX bundlers) lose multi-user collaboration and permissions; database-first tools (Sanity, Contentful, Strapi) lose the developer-friendly file editing flow. MDCMS keeps both — the database is canonical, but the local file experience is real, not a sync hack.
+
+## Who it's for
+
+- **Developers** building React/Next.js/Remix sites who want to edit content in their editor and ship it through git-like workflows.
+- **Editors** in those teams who need a real GUI for content work — Studio is for them.
+- **AI agents** that want a typed, scoped HTTP API to read and write content without scraping a UI.
+
+The core thesis is that **none of the three should block the others**. An editor publishing a page and an agent rewriting 500 posts at once go through the same validation, the same permissions, and the same version history.
+
+## Core architecture
+
+- **`apps/server`** is the canonical source of truth. Elysia + PostgreSQL + Drizzle. Every read/write hits this.
+- **`apps/cli`** owns push/pull/sync — file ↔ database reconciliation, auth via loopback OAuth flow.
+- **`packages/studio`** is an embeddable React component the host app mounts at a catch-all route.
+- **`packages/sdk`** is a thin read-only client.
+- **`packages/shared`** holds Zod contracts and types every other package imports.
+- **`packages/modules`** is the first-party module registry — both server-side (`installedModules`) and CLI-side discovery is deterministic and ordered.
+
+## Out of scope (current)
+
+- Real-time multi-user collaboration via CRDTs — Post-MVP.
+- Live preview (real-time content rendering in the consumer frontend) — upcoming.
+- MCP integration for agent-driven content operations — upcoming.
+- Multiple spaces (team-scoped content organization) — upcoming.

+# Stack
+
+Runtime, dependencies, and infrastructure. Update when any of them change.
+
+## Runtime + tooling
+
+- **Bun** is the package manager AND the test runner (`bun test`).
+- **Nx 22.5** orchestrates tasks across the monorepo with `@nx/js/typescript` plugin.
+- **TypeScript 5.9**, strict mode, `nodenext` module resolution, `composite` projects (project references).
+
+## Backend
+
+- **Elysia** (HTTP framework) running on Bun.
+- **Drizzle ORM** with `postgres.js` driver against **PostgreSQL 16**. Sessions, content, auth, and audit logs all live in Postgres.
+- **Redis** is provisioned in the dev stack (`REDIS_URL` env var); reserved for future use (caching, queues, rate-limiting). Not currently a session store.
+- **MinIO** (S3-compatible) for media.
+
+## Frontend
+
+- **React** for Studio.
+- **TanStack Query** for client-side data fetching.
+- **TanStack Router** for typed routing in the dashboard.
+- **TipTap** for the editor with MDX component support.
+
+## Validation
+
+- **Zod 4** for runtime validation.
+- **Standard Schema** for content type definitions (ecosystem interop).
+
+## Infrastructure (dev)
+
+- `docker compose up -d --build` brings up postgres, redis, minio, mailhog.
+- Server runs on port 4000.
+
+## Custom export condition
+
+`@mdcms/source` resolves to TypeScript source files during development. Production builds resolve through `import`/`default` to `dist/`. Every package's `package.json` exports must include this condition.
+
+## Constraints worth knowing
+
+- **Bun-only.** Do not introduce Node-only dependencies that don't run on Bun.
+- **No runtime ORM relationships across modules.** First-party modules in `packages/modules/<id>/` use foreign-key IDs only — never direct relations between modules. (Hard rule from architecture.)
+- **Tenant scoping is mandatory.** Every persistable row carries `project_id` (or equivalent boundary key). Queries must filter on it.
+- **Pre-push hook** runs `bun run ci:required` — typecheck + format check + unit tests + integration must all pass.
+- **Pre-commit checks:** `bun run format:check` and `bun run check`.
+
+## Things that are NOT in the stack (yet)
+
+- No CRDT library (real-time collab is Post-MVP).
+- No MCP server (AI agent integration is upcoming, separate work).
+- No live preview pipeline (upcoming).
+
+## Repository services
+
+- Issue tracker: GitHub Issues.
+- CI: GitHub Actions (see `.github/workflows/`).
+- Docs deploy: `docs.mdcms.ai` (separate pipeline).

+# Auth flow
+
+## What it is
+
+Three authentication modes coexist in MDCMS, each suited to a different surface:
+
+- **Session** — browser-based, used by Studio. Server-issued, cookie-bound, stored in the Postgres `sessions` table.
+- **API key** — long-lived bearer token. Used by SDK consumers and any non-interactive client. Carries scopes.
+- **Loopback OAuth flow** — CLI's browser-based auth handoff using OAuth2 with a localhost callback (RFC 8252). Trades a one-time authorization code (with `state` validation) for an API key stored in the user's local CLI config.
+
+All three resolve to the same internal concept downstream: an authenticated principal with a project context and a set of scopes.
+
+## How it works
+
+### Session (Studio)
+
+Browser sessions are persisted server-side; the `sessions` table in `apps/server/src/lib/db/schema.ts` holds them with a unique-token index. Studio fetches the active principal on mount and caches it in its TanStack Query layer; writes carry CSRF protection.
+
+### API key (SDK / non-interactive)
+
+Clients construct `createClient({ url, apiKey, project, environment })` and send `Authorization: Bearer <api-key>` on every request. The server resolves `key → principal → project ACL → scopes → request`. The SDK is read-only by design; writes go directly to the server.
+
+### Loopback OAuth flow (CLI)
+
+1. `mdcms login` starts a local HTTP listener (`createCallbackListener` in `apps/cli/src/lib/login.ts`) bound to `127.0.0.1` on an ephemeral port. Callback path is `/callback`.
+2. CLI opens a browser to the server's authorization page with the `redirectUri` (e.g. `http://127.0.0.1:54321/callback`), a one-time `state` value, and a server-issued `challengeId`.
+3. User authenticates in the browser. Server redirects to the loopback URL with `code` + `state`.
+4. The local listener validates that the inbound `state` matches the value the CLI sent (CSRF protection).
+5. CLI exchanges the `code` with the server for an API key.
+6. Key is stored in the user's CLI credential store. Subsequent CLI commands use it as a bearer token.
+
+If the listener doesn't receive a callback within a timeout, the CLI surfaces "Timed out waiting for browser callback. Please retry `mdcms login`."
+
+## Guarantees / invariants
+
+- Every authenticated request resolves a project context **before** reaching domain code. No cross-tenant leak via missing scoping.
+- API keys carry scopes; sessions inherit scopes from the user's role.
+- The loopback flow validates `state` to defeat CSRF; binding to `127.0.0.1` confines redirect targets to the local machine.
+- API keys are revocable; sessions are revocable; both invalidate immediately on the server.
+
+## Cross-refs

+- Spec: `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
+- Per-package: `apps/server/AGENTS.md`, `apps/cli/AGENTS.md`

+# Module system
+
+## What it is
+
+The extensibility mechanism. New capabilities — server actions, CLI commands, Studio UI surfaces, content types, validation hooks — are added as **modules** rather than by patching core code. First-party modules (e.g. `core.system`, `domain.content`) live in `packages/modules/<module-id>/`. Third-party modules are external npm packages that register against the same contract.
+
+## How it works
+
+### Module shape
+
+Every module ships:
+
+- `manifest.ts` — metadata (id, version, capabilities, dependencies).
+- `server/index.ts` — server-side surfaces (HTTP routes, event handlers, jobs).
+- `cli/index.ts` — CLI subcommands.
+- Optional `studio/index.tsx` — UI surfaces.
+
+### Registration
+
+- The `installedModules` registry in `packages/modules/src/index.ts` is a deterministic, sorted-by-`manifest.id` array.
+- Server and CLI each have their own `module-loader.ts` that walks the registry at startup and mounts each module's surfaces.
+- Studio loads its module bundle from the server at runtime — the host app doesn't bundle modules at build time.
+
+### Cross-module dependencies
+
+- Modules **must not** create direct ORM relationships across module boundaries. Use foreign-key IDs only.
+- Cross-module communication goes through declared interfaces in `@mdcms/shared`, never direct imports between module packages.
+- A module can declare it depends on another module's interface; the loader fails fast if a dependency is missing.
+
+## Guarantees / invariants
+
+- **Deterministic load order.** Same registry → same load order across machines. No environment-dependent ordering.
+- **No cross-module ORM relations.** Hard rule. Enforced by code review (and ideally a lint rule eventually).
+- **Server / CLI / Studio share the same registry source of truth.** The list of installed modules is one decision, not three.
+- **Modules don't patch core.** If a feature would require modifying core, it's not a module — promote to core or rethink the abstraction.
+
+## Cross-refs
+
+- Spec: `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
+- Per-package: `packages/modules/`, `apps/server/AGENTS.md`, `apps/cli/AGENTS.md`
+- Related: [`schema-sync.md`](schema-sync.md) — content types are typically delivered via modules
+
+## Why this matters
+
+A CMS without an extensibility story becomes a monolith customers fork to extend. The module contract forces "it's a module or it's core" decisions early, which keeps the core surface small.

+# Multi-tenancy
+
+## What it is
+
+Project is the top-level isolation boundary in MDCMS. Every **tenant-scoped** entity — documents, content types, schemas, API keys, audit-log entries — carries a `project_id`. (User-bound entities like sessions and accounts are not project-scoped; they resolve a project context per request based on the explicit project parameter or the API key's binding.) Within a project, **environment** (e.g. `draft`, `prod`) is a state dimension that further scopes reads and writes.
+
+This is the multi-tenant model — a single MDCMS server hosts arbitrary projects, and tenant code never sees data from another tenant.
+
+## How it works
+
+### Project resolution
+
+1. Every authenticated request resolves a project context **before** reaching domain code.
+2. Project comes from one of:
+   - Explicit header / parameter (SDK clients pass `project` in `createClient`).
+   - The api key's bound project (api keys are project-scoped).
+   - The session's active project (Studio).
+3. If a request can't resolve a project, it errors at the route layer — no domain code runs without a tenant.
+
+### Environment scoping
+
+1. Reads default to the **published environment** unless the request explicitly opts into another.
+2. Writes target a specific environment — usually `draft` for editorial workflows, `prod` after publish.
+3. Publishing is a state transition that copies/promotes a draft document into the prod environment.
+4. Locales further scope translatable documents — a single document has a per-locale variant, all sharing the same project + environment context.
+
+### Storage layer
+
+- Every persistable row has a `project_id` (foreign key) plus, where relevant, `environment` and `locale` columns.
+- Drizzle queries **must** filter by `project_id`. There's no global query path.
+- Indexes are composite, leading with `project_id`.
+
+## Guarantees / invariants
+
+- **No cross-tenant data leak.** A misconfigured query that omits `project_id` is a bug; should be caught in code review and ideally by lint rules.
+- **API keys are project-bound.** A leaked key compromises one project, not all projects on the server.
+- **Project deletion cascades.** Deleting a project removes all its documents, schemas, audit entries, and api keys.
+- **Environment isolation is logical, not physical.** All environments share the same database tables; isolation comes from the `environment` column, not separate schemas/databases.
+
+## Cross-refs
+
+- Spec: `docs/specs/SPEC-001-platform-overview-and-scope.md`, `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
+- Per-package: `apps/server/AGENTS.md`
+- Related: [`auth-flow.md`](auth-flow.md) for how project resolution interacts with each auth mode
+- Related: [`push-pull-sync.md`](push-pull-sync.md) for how environment scoping affects CLI operations
+
+## Future scope
+
+**Multiple spaces** (team-scoped content organization within a project) is on the upcoming-work list. The shape and exact column names are not yet specified — defer to the relevant spec under `docs/specs/` once it lands. Until then, don't assume a particular schema or boundary; just keep tenant-scoping code shaped for additional future scopes without restructuring.

+# Push / pull sync
+
+## What it is
+
+The CLI's file ↔ database reconciliation. The database is canonical (server-side); local `.md`/`.mdx` files are a working copy. The two operations are deliberately one-directional:
+
+- **`mdcms pull`** — fetch documents from the server to local files. Overwrites local with server state for the targeted scope.
+- **`mdcms push`** — upload local file changes back to the server. Conflict-checked against the server's current state via document version headers.
+
+The full CLI command set is `init`, `login`, `logout`, `pull`, `push`, `schema-sync`, `status` (registered in `apps/cli/src/lib/framework.ts`).
+
+## How it works
+
+### Pull
+
+1. CLI authenticates with the stored API key from the credential store.
+2. CLI requests document set scoped to project + environment + locale + content-type filters.
+3. Server returns documents with their current version metadata.
+4. CLI writes `.md`/`.mdx` files to the configured local directory (`mdcms.config.ts` `contentDir`).
+5. Each file's frontmatter carries metadata: id, version, environment, locale, references.
+
+### Push
+
+1. CLI scans local files in `contentDir`.
+2. For each changed file, CLI sends the request with version-tracking headers:
+   - `x-mdcms-project` and `x-mdcms-environment` for routing context
+   - `x-mdcms-schema-hash` to pin against the schema the file was authored under
+   - `x-mdcms-draft-revision` and `x-mdcms-published-version` to detect server-side drift since the last pull
+3. Server validates against the current schema, applies edits, returns the new version.
+4. CLI updates local cache to the new version.
+5. If the server's version moved since the last pull, the request is rejected as a conflict; CLI surfaces a structured conflict and stops. User resolves manually.
+
+### Status
+
+`mdcms status` shows pending local changes and known conflicts without writing anything.
+
+## Guarantees / invariants
+
+- **Database is the source of truth.** Pull overwrites local; push commits to server with version checks.
+- **No silent merge.** Conflicts halt push; resolution is explicit.
+- **Schema-checked at push.** The `x-mdcms-schema-hash` header pins the request against the schema the file was authored under (see ADR-006). Server rejects pushes against stale schemas before any partial write.
+- **Environment + locale isolation.** Pull/push are scoped — pulling `prod` never overwrites `draft` and vice versa.
+
+## Cross-refs

+- Spec: `docs/specs/SPEC-008-cli-and-sdk.md`, `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
+- ADR: `docs/adrs/ADR-006-schema-hash-pinning-for-write-clients.md`

+- Related: [`schema-sync.md`](schema-sync.md) for the schema-side equivalent flow
+
+## What this is _not_
+
+- Not a CRDT or real-time collab system — that's Post-MVP.
+- Not git. Doesn't track history client-side beyond the last-pull cache. Server holds the version history.
+- Not symmetric — pull and push are one-way each. There's no "merge" command.

+# Schema sync
+
+## What it is
+
+How content type definitions in the user's `mdcms.config.ts` reach the server's schema registry. Schema is what gives MDCMS its typed editing surface — Studio forms, validation rules, and component catalogs are all generated from it.
+
+Schema sync is **schema-first**: developers edit `mdcms.config.ts`, run `mdcms schema sync`, and the server's registry catches up. The server never invents schema unilaterally.
+
+## How it works
+
+1. Developer edits `mdcms.config.ts` (defines content types, fields, references via `defineConfig`, `defineType`, `reference` from `@mdcms/shared`).
+2. `mdcms schema sync` parses the config, computes a content-addressable hash of the resulting Standard Schema definitions, and POSTs to the server's schema endpoint.
+3. Server compares incoming hash with the registry's current hash for that project.
+4. If matched → no-op, success.
+5. If different → server validates the new schema (no breaking changes without an explicit override flag), persists the new schema record, and updates the active hash.
+6. Subsequent reads/writes use the new schema. Documents authored against an old hash get migrated lazily or rejected based on the change type.
+
+## Guarantees / invariants
+
+- **Schema hash pinning** for write clients (per ADR-006). Writes carry the schema hash they were authored against; mismatch is detected and surfaced.
+- **No silent breaking changes.** Removing a required field or changing a type without a migration path requires an explicit override.
+- **Standard Schema interop.** Internal representation uses Standard Schema so adapters into Zod, Valibot, Arktype etc. work out of the box.
+- **Project-scoped.** Schema is per project (multi-tenant boundary). Two projects with identical schemas are still separate registry entries.
+
+## Cross-refs
+
+- Spec: `docs/specs/SPEC-004-schema-system-and-sync.md`
+- ADR: `docs/adrs/ADR-006-schema-hash-pinning-for-write-clients.md`
+- Per-package: `apps/cli/AGENTS.md`, `packages/shared/AGENTS.md`
+- Related: [`push-pull-sync.md`](push-pull-sync.md) — schema sync runs separately from content push/pull
+
+## What this is _not_
+
+- Not a database migration tool. The server's Drizzle migrations are independent.
+- Not pushed automatically by Studio or SDK consumers. Studio reads the active schema; SDK reads documents typed against it. Schema authoring is CLI-only.

+# CMS-16 Environment Overlay Resolver Design
+
+## Scope
+
+Implement the shared resolver foundation for environment-specific schema overlays in `mdcms.config.ts`.
+
+This design is intentionally limited to resolver behavior in shared config parsing and CLI config loading. It does not add schema registry endpoints or thread resolved schemas into server content read/write paths yet.
+
+## Spec Delta
+
+- No `SPEC.md` change is required for this design.
+- This work implements the existing spec and roadmap contract for:
+  - environment overlays via `add`, `modify`, and `omit`
+  - field-level `.env()` sugar
+  - environment inheritance via `extends`
+
+## Goals
+
+- Produce deterministic resolved schemas per environment.
+- Preserve the current package boundaries by keeping the authoring and resolver contract in `@mdcms/shared`.
+- Keep the output shape reusable for `CMS-17` schema sync and later server-side validation consumers.
+- Fail invalid authoring configurations with actionable `INVALID_CONFIG` errors.
+
+## Non-Goals
+
+- No schema registry persistence or hash endpoints.
+- No server runtime consumption of resolved schemas yet.
+- No changes to content API behavior in this task.
+
+## Authoring Contract
+
+### Base Types
+
+`defineType(name, definition)` continues to define the base type shared across environments.
+
+### Overlay Authoring
+
+Each type definition exposes `.extend(...)` for environment-local overlays:
+
+```ts
+const blogPost = defineType("BlogPost", {
+  directory: "content/blog",
+  localized: true,
+  fields: {
+    title: z.string().min(1).max(200),
+    slug: z.string().regex(/^[a-z0-9-]+$/),
+    author: reference("Author"),
+    tags: z.array(z.string()).default([]),
+    featured: z.boolean().default(false).env("staging", "preview"),
+    abTestVariant: z.enum(["control", "a", "b"]).optional().env("preview"),
+  },
+});
+
+export default defineConfig({
+  project: "marketing-site",
+  serverUrl: "http://localhost:4000",
+  contentDirectories: ["content"],
+  types: [blogPost],
+  locales: {
+    default: "en-US",
+    supported: ["en-US", "fr"],
+  },
+  environments: {
+    production: {},
+    staging: {
+      extends: "production",
+      types: {
+        BlogPost: blogPost.extend({
+          modify: {
+            tags: z.array(z.string()).min(1),
+          },
+        }),
+      },
+    },
+    preview: {
+      extends: "staging",
+      types: {
+        BlogPost: blogPost.extend({
+          add: {
+            reviewerNotes: z.string().optional(),
+          },
+          omit: ["slug"],
+        }),
+      },
+    },
+  },
+});
+```
+
+## Resolver Model
+
+The resolver runs in three phases inside the shared config contract.
+
+### 1. Parse Authoring Input
+
+- Parse base config fields as in `CMS-15`.
+- Parse type definitions and Standard Schema-compatible fields.
+- Parse environment overlay definitions:
+  - `extends?: string`
+  - `types?: Record<string, ParsedTypeOverlay>`
+- Attach MDCMS metadata for:
+  - reference fields
+  - `.env()` sugar targets
+
+### 2. Normalize Overlay Sources
+
+- Convert explicit `extend({ add, modify, omit })` payloads into a normalized internal overlay shape.
+- Expand field-level `.env(...targets)` metadata into synthetic environment `add` overlays for the owning type.
+- Reject conflicts where the same environment/type/field is introduced both by sugar expansion and explicit overlay input.
+
+### 3. Resolve Environments
+
+- Resolve each environment independently but deterministically.
+- Apply inheritance parent-first, then child overlay.
+- Each environment level contributes only its incremental changes.
+- The resolved output includes fully materialized per-environment type definitions and field maps in stable order.
+
+## Deterministic Rules
+
+- Base type fields are the source schema for environments with no overlays.
+- `.env()` fields do not exist in the base resolved field set. They are only added to the targeted environments.
+- `extends` chains resolve from ancestor to descendant.
+- `add` may only introduce a field that does not yet exist in the inherited schema at that resolution point.
+- `modify` may only target a field that already exists in the inherited schema at that resolution point.
+- `omit` may only remove a field that already exists in the inherited schema at that resolution point.
+- Environment names, type names, overlay maps, and resolved field names are sorted before output to make hashing and snapshots deterministic.
+
+## Error Handling
+
+All authoring failures are surfaced as `RuntimeError` with `code: "INVALID_CONFIG"`.
+
+### Environment Graph Errors
+
+- unknown `extends` target
+- self-referential `extends`
+- circular inheritance chains
+
+Error messages must include the environment name and, for cycles, the full discovered chain.
+
+### Overlay Target Errors
+
+- overlay references an unknown type
+- `add` targets an already-present field
+- `modify` targets a missing field
+- `omit` targets a missing field
+
+Error messages must include environment, type, and field context.
+
+### Sugar Conflicts
+
+- `.env()` expansion and explicit overlay both try to define the same added field for the same environment/type
+
+The diagnostic must direct the user to keep one source of truth.
+
+## Public Output Shape
+
+`parseMdcmsConfig(...)` should continue to return the normalized base config and also expose deterministic resolved environment output for downstream tasks.
+
+Expected additions:
+
+- parsed `environments` definitions
+- `resolvedEnvironments` map keyed by environment name
+- resolved type definitions that preserve:
+  - name
+  - directory
+  - localized
+  - resolved `fields`
+  - resolved `referenceFields`
+
+This keeps `CMS-17` from needing to re-implement overlay resolution.
+
+## Documentation
+
+Point-of-use docs should be updated in:
+
+- `packages/shared/README.md`
+- `apps/cli/README.md`
+
+Documentation should explain:
+
+- how `extends` works
+- when to use `add` vs `modify` vs `omit`
+- how `.env()` expands
+- that this task only defines resolver behavior, with server consumption deferred to later tasks
+
+## Testing
+
+### Shared Unit Tests
+
+Expand `packages/shared/src/lib/contracts/config.test.ts` with:
+
+- deterministic per-environment resolution
+- multi-hop inheritance resolution
+- `.env()` sugar expansion
+- sugar vs explicit overlay conflict rejection
+- missing parent rejection
+- self-cycle rejection
+- multi-node cycle rejection
+- invalid `add`
+- invalid `modify`
+- invalid `omit`
+
+### CLI Coverage
+
+Extend `apps/cli/src/lib/config.test.ts` to prove CLI config loading returns the new resolved environment output unchanged from the shared parser.
+
+## Implementation Notes
+
+- Keep the resolver library-agnostic at the public boundary by continuing to accept Standard Schema-compatible field validators.
+- Use schema metadata rather than introducing server-only coupling.
+- Do not thread resolved schemas into server content APIs in this task.

+# CMS-16 Environment Overlay Resolver Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Implement deterministic environment overlay resolution for `mdcms.config.ts`, including `add` / `modify` / `omit`, `.env()` sugar, and `extends` inheritance, without wiring resolved schemas into server content APIs yet.
+
+**Architecture:** Extend the shared config contract in `@mdcms/shared` so base type definitions, environment overlays, and field metadata are parsed and normalized in one place. Resolve overlays parent-first into stable per-environment type maps, then expose that output through the existing CLI config loader so later schema-sync tasks can consume a canonical resolved snapshot.
+
+**Tech Stack:** TypeScript, Bun test runner, Zod 4 metadata, Nx monorepo package boundaries
+
+---
+
+### Task 1: Add Shared Overlay Authoring Surface
+
+**Files:**
+
+- Modify: `packages/shared/src/lib/contracts/config.ts`
+- Test: `packages/shared/src/lib/contracts/config.test.ts`
+
+**Step 1: Write the failing test**
+
+Add a shared config test that authors environment overlays with `.extend({ add, modify, omit })` and asserts `parseMdcmsConfig(...)` returns parsed environment metadata plus deterministic `resolvedEnvironments`.
+
+```ts
+test("parseMdcmsConfig resolves environment overlays and env sugar deterministically", () => {
+  const blogPost = defineType("BlogPost", {
+    directory: "content/blog",
+    localized: true,
+    fields: {
+      title: z.string(),
+      slug: z.string(),
+      tags: z.array(z.string()).default([]),
+      featured: z.boolean().default(false).env("staging", "preview"),
+    },
+  });
+
+  const parsed = parseMdcmsConfig(
+    defineConfig({
+      project: "marketing-site",
+      serverUrl: "http://localhost:4000",
+      contentDirectories: ["content"],
+      locales: { default: "en-US", supported: ["en-US"] },
+      types: [blogPost],
+      environments: {
+        production: {},
+        staging: {
+          extends: "production",
+          types: {
+            BlogPost: blogPost.extend({
+              modify: {
+                tags: z.array(z.string()).min(1),
+              },
+            }),
+          },
+        },
+      },
+    }),
+  );
+
+  assert.deepEqual(Object.keys(parsed.resolvedEnvironments), [
+    "production",
+    "staging",
+  ]);
+  assert.equal(
+    parsed.resolvedEnvironments.staging.types.BlogPost.fields.featured !==
+      undefined,
+    true,
+  );
+});
+```
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test packages/shared/src/lib/contracts/config.test.ts`
+Expected: FAIL because `defineType(...).extend`, `.env(...)`, `environments`, or `resolvedEnvironments` do not exist yet.
+
+**Step 3: Write minimal implementation**
+
+In `packages/shared/src/lib/contracts/config.ts`:
+
+- add authoring types for environment overlays
+- update `defineType(...)` to return an object with `.extend(...)`
+- add metadata helpers for `.env(...)`
+- parse `config.environments`
+- add parsed/resolved config output types
+
+Representative structure:
+
+```ts
+export type MdcmsTypeOverlay = {
+  add?: Record<string, MdcmsFieldSchema>;
+  modify?: Record<string, MdcmsFieldSchema>;
+  omit?: string[];
+};
+
+export type MdcmsEnvironmentDefinition = {
+  extends?: string;
+  types?: Record<string, MdcmsTypeOverlay>;
+};
+
+export type ParsedResolvedEnvironment = {
+  types: Record<string, ParsedMdcmsTypeDefinition>;
+};
+
+function createTypeDefinition<
+  TName extends string,
+  TFields extends Record<string, MdcmsFieldSchema>,
+>(
+  name: TName,
+  definition: {
+    directory?: string;
+    localized?: boolean;
+    fields: TFields;
+  },
+): MdcmsTypeDefinition<TName, TFields> {
+  return {
+    name,
+    ...definition,
+    extend(overlay) {
+      return overlay;
+    },
+  };
+}
+```
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test packages/shared/src/lib/contracts/config.test.ts`
+Expected: PASS for the new resolution-path test, even if later failure-path tests are still missing.
+
+**Step 5: Commit**
+
+```bash
+git add packages/shared/src/lib/contracts/config.ts packages/shared/src/lib/contracts/config.test.ts
+git commit -m "feat(shared): add environment overlay config surface"
+```
+
+### Task 2: Implement Resolver Validation and Error Paths
+
+**Files:**
+
+- Modify: `packages/shared/src/lib/contracts/config.ts`
+- Test: `packages/shared/src/lib/contracts/config.test.ts`
+
+**Step 1: Write the failing tests**
+
+Add targeted tests for:
+
+- missing `extends` target
+- self-cycle
+- multi-node cycle
+- `.env()` plus explicit `add` conflict
+- invalid `add`
+- invalid `modify`
+- invalid `omit`
+
+Example failure test:
+
+```ts
+test("parseMdcmsConfig rejects circular extends chains", () => {

+Run: `bun test packages/shared/src/lib/contracts/config.test.ts`
+Expected: FAIL because cycles/conflicts are not yet rejected with stable diagnostics.

+**Step 3: Write minimal implementation**
+
+Add resolver helpers in `packages/shared/src/lib/contracts/config.ts`:
+
+- `parseEnvironments(...)`
+- `extractEnvFieldTargets(...)`
+- `expandEnvSugar(...)`
+- `resolveEnvironmentChain(...)`
+- `applyTypeOverlay(...)`
+
+Representative core logic:

+
+**Step 1: Write the failing test**
+
+Extend the CLI config loader test to assert `loadCliConfig(...)` exposes the resolved environment output.
+
+```ts
+test("loadCliConfig returns resolved environment schemas from the shared parser", async () => {
+  const { cwd } = await writeConfigFile(`

+# CMS-17 Schema Registry Endpoints Design
+
+## Scope
+
+Implement the schema registry foundation for:
+
+- `GET /api/v1/schema`
+- `GET /api/v1/schema/:type`
+- `PUT /api/v1/schema`
+
+This task covers registry persistence, read/write API contracts, hash tracking,
+and deterministic error handling for raw and resolved schema snapshots.
+
+## Spec Delta
+
+`SPEC.md` already defines the route surface, auth scopes, target routing, and
+the top-level `PUT /api/v1/schema` success envelope. This design defines the
+missing contract details that must be reflected in `SPEC.md` before or alongside
+implementation:
+
+- `SchemaRegistryEntry` response shape
+- registry storage model
+- descriptive snapshot limitations
+- deterministic `INVALID_INPUT` vs `SCHEMA_INCOMPATIBLE` semantics
+
+## Goals
+
+- Persist the latest schema sync state per `(project, environment)`.
+- Return one registry entry per schema type for the target environment.
+- Support stable hash comparison and sync metadata reads.
+- Fail unsupported or unserializable schema features deterministically.
+- Reserve `409 SCHEMA_INCOMPATIBLE` for migration-requiring schema conflicts
+  rather than malformed payloads.
+
+## Non-Goals
+
+- No schema sync history beyond the latest state per target environment.
+- No exact reconstruction of executable Zod or Standard Schema validators.
+- No content migration execution in this task.
+- No Studio schema editing UI.
+
+## Chosen Model
+
+### Registry Read Model
+
+The registry is type-centric.
+
+- `GET /api/v1/schema` returns one `SchemaRegistryEntry` per type for the target
+  `(project, environment)`.
+- `GET /api/v1/schema/:type` returns a single `SchemaRegistryEntry`.
+- `PUT /api/v1/schema` writes environment-level sync metadata and derives the
+  per-type registry rows from the uploaded resolved schema snapshot.
+
+### Sync History
+
+Sync history is out of scope for `CMS-17`.
+
+The registry stores only the latest sync state per `(project, environment)`.
+Current spec and roadmap text require read/write registry behavior and hash
+comparison, but do not require historical sync records.
+
+## Snapshot Fidelity
+
+The schema registry stores descriptive JSON snapshots, not executable validator
+objects.
+
+This is an explicit limitation of `CMS-17`.
+
+- Stored schema data is suitable for:
+  - hash comparison
+  - schema mismatch detection
+  - read-only Studio schema display
+  - future introspection based on descriptive metadata
+- Stored schema data is not suitable for exact reconstruction of runtime
+  validator behavior.
+
+### Unsupported Features
+
+The registry must reject schema payloads that depend on executable or otherwise
+unserializable behavior that cannot be represented losslessly in the descriptive
+snapshot model.
+
+Examples include:
+
+- `.refine()`
+- `.superRefine()`
+- `transform`
+- `preprocess`
+- arbitrary functions
+- non-JSON values
+- any custom validator behavior that cannot be preserved in the registry JSON
+
+These failures are `INVALID_INPUT` (`400`), not compatibility conflicts.
+
+## Public API Contract
+
+### PUT `/api/v1/schema`
+
+Request body:
+
+```ts
+{
+  rawConfigSnapshot: Record<string, unknown>;
+  resolvedSchema: Record<string, Record<string, unknown>>;
+  schemaHash: string;
+  extractedComponents?: unknown;
+}
+```
+
+Behavior:
+
+- validates the request body shape
+- validates that the payload can be represented by the descriptive registry
+  model
+- validates compatibility against the currently stored registry and current
+  content rows
+- upserts the environment-level sync row
+- replaces the environment's derived per-type registry rows in a single
+  transaction
+
+Success response:
+
+```ts
+{
+  data: {
+    schemaHash: string;
+    syncedAt: string;
+    affectedTypes: string[];
+  };
+}
+```
+
+### GET `/api/v1/schema`
+
+Success response:
+
+```ts
+{
+  data: SchemaRegistryEntry[];
+}
+```
+
+### GET `/api/v1/schema/:type`
+
+Success response:
+
+```ts
+{
+  data: SchemaRegistryEntry;
+}
+```
+
+### SchemaRegistryEntry
+
+```ts
+type SchemaRegistryEntry = {
+  type: string;
+  directory: string;
+  localized: boolean;
+  schemaHash: string;
+  syncedAt: string;
+  resolvedSchema: Record<string, unknown>;
+};
+```
+
+Notes:
+
+- `schemaHash` and `syncedAt` are duplicated across entries for a given target
+  environment. This keeps the current route contract simple without introducing
+  a new top-level metadata envelope.
+- `rawConfigSnapshot` is stored at the environment sync level and is not
+  returned by `GET` endpoints.
+
+## Storage Model
+
+Use two tables.
+
+### 1. Environment-Level Sync Table
+
+One row per `(project_id, environment_id)`.
+
+Suggested shape:
+
+```ts
+schema_syncs = {
+  id: uuid,
+  projectId: uuid,
+  environmentId: uuid,
+  schemaHash: text,
+  rawConfigSnapshot: jsonb,
+  extractedComponents: jsonb | null,
+  syncedAt: timestamptz,
+};
+```
+
+Constraints and indexing:
+
+- unique on `(project_id, environment_id)`
+- composite foreign key to `(environments.id, environments.project_id)`
+- scope index on `(project_id, environment_id)`
+
+### 2. Per-Type Registry Table
+
+One row per `(project_id, environment_id, schema_type)`.
+
+Suggested shape:
+
+```ts
+schema_registry_entries = {
+  id: uuid,
+  projectId: uuid,
+  environmentId: uuid,
+  schemaType: text,
+  directory: text,
+  localized: boolean,
+  schemaHash: text,
+  resolvedSchema: jsonb,
+  syncedAt: timestamptz,
+};
+```
+
+Constraints and indexing:
+
+- unique on `(project_id, environment_id, schema_type)`
+- composite foreign key to `(environments.id, environments.project_id)`
+- scope index on `(project_id, environment_id, schema_type)`
+
+## Validation and Errors
+
+### `400 INVALID_INPUT`
+
+Used when the request is malformed or the registry cannot preserve the uploaded
+schema payload in its descriptive snapshot model.
+
+Examples:
+
+- missing or malformed top-level request fields
+- `resolvedSchema` is not a type map
+- a type entry is missing required descriptive fields
+- unsupported or unserializable validator features
+- non-JSON values
+
+Diagnostics must be actionable and point to the failing type/field/path when
+possible.
+
+### `409 SCHEMA_INCOMPATIBLE`
+
+Used only when the payload is valid and serializable, but applying it would
+conflict with existing content and should require a migration first.
+
+For `CMS-17`, compatibility checks stay structural and coarse-grained.
+
+Examples:
+
+- removing a type that still has documents in the target environment
+- changing localization mode in a way that conflicts with existing documents
+- removing a supported locale that still has documents
+- making a previously optional or absent field required for a type that already
+  has documents
+- changing a field's coarse kind in a clearly breaking way for existing content
+  such as:
+  - scalar to array
+  - array to scalar
+  - object to scalar
+  - reference target `Author` to `Category`
+
+Anything the registry cannot structurally reason about stays out of `409` and is
+either accepted or rejected as `400` depending on serializability.
+
+## Authorization and Routing
+
+- `/api/v1/schema*` remains explicitly scoped by `(project, environment)` via
+  the existing target routing guard.
+- `GET` routes require `schema:read`.
+- `PUT` requires `schema:write`.
+- Session-based RBAC mapping must be extended so privileged Studio users are
+  actually constrained by the schema scopes already defined for API keys.
+
+## Server Architecture
+
+Add a dedicated schema API module:
+
+- `apps/server/src/lib/schema-api.ts`
+
+Responsibilities:
+
+- request parsing and validation
+- route mounting
+- compatibility checks
+- DB-backed registry store
+- API response shaping
+
+Mount it from the shared server bootstrap alongside auth, content, and
+collaboration routes.
+
+Shared request/response contracts should live in:
+
+- `packages/shared/src/lib/contracts/schema.ts`
+
+## Persistence Rules
+
+- schema sync never mutates content rows
+- `PUT /api/v1/schema` replaces only registry state for the target environment
+- all writes happen transactionally:
+  - upsert environment sync row
+  - delete stale type rows for the target environment
+  - insert replacement type rows
+
+## Documentation
+
+Point-of-use docs should be updated in:
+
+- `SPEC.md`
+- `apps/cli/README.md`
+- `packages/shared/README.md`
+
+The docs must explicitly call out:
+
+- the descriptive snapshot limitation
+- unsupported validator features
+- the `400` vs `409` error split
+- that schema sync updates the registry only and does not mutate content rows
+
+## Testing
+
+### Shared Contract Tests
+
+Add shared tests for:
+
+- request and response shape validation
+- serializer rejection of unsupported features
+- deterministic hash and entry ordering behavior where applicable
+
+### Server API Contract Tests
+
+Add endpoint tests covering:
+
+- `GET /schema` success
+- `GET /schema/:type` success
+- `GET /schema/:type` not found
+- `PUT /schema` success
+- `PUT /schema` malformed request -> `400`
+- `PUT /schema` unsupported/unserializable schema -> `400`
+- `PUT /schema` compatibility conflict -> `409`
+- explicit target routing enforcement
+- auth scope enforcement for both API keys and sessions
+
+### Database Contract Tests
+
+Add DB contract coverage for:
+
+- new schema registry tables
+- unique constraints
+- composite environment/project foreign keys
+- scope indexes
+
+## Implementation Notes
+
+- The server should treat uploaded schema payloads as descriptive data, not as a
+  source of executable validators.
+- The serializer contract should be strict and fail closed when it encounters
+  unsupported features.
+- Compatibility checks should stay minimal, deterministic, and structural in
+  `CMS-17`.

+# CMS-17 Schema Registry Endpoints Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Implement `/api/v1/schema`, `/api/v1/schema/:type`, and `PUT /api/v1/schema` with latest-state registry persistence, schema hash tracking, deterministic `400` vs `409` behavior, and target-scoped auth/routing.
+
+**Architecture:** Add a new shared schema contract layer for registry payload validation and descriptive snapshot serialization, persist latest sync metadata plus derived per-type rows in new server DB tables, and expose a dedicated server route module wired alongside auth/content routes. Keep the registry descriptive only: unsupported executable validator features fail closed with `INVALID_INPUT`, while coarse migration-requiring conflicts return `SCHEMA_INCOMPATIBLE`.
+
+**Tech Stack:** Bun, Nx, TypeScript, Drizzle ORM/Postgres, Elysia, shared `RuntimeError` envelopes, existing target-routing/auth infrastructure.
+
+---
+
+### Task 0: Lock The Approved Spec Delta Locally
+
+**Files:**
+
+- Modify: `SPEC.md` (local-only, do not stage/commit)
+- Reference: `docs/plans/2026-03-11-cms-17-design.md`
+
+**Step 1: Add the missing schema registry contract details to the local spec**
+
+Add the approved details from the design doc:
+
+- `SchemaRegistryEntry` shape
+- latest-state registry model
+- descriptive snapshot limitation
+- unsupported feature rejection semantics
+- `INVALID_INPUT` vs `SCHEMA_INCOMPATIBLE`
+
+**Step 2: Verify the local spec contains the approved contract**
+
+Run: `rg -n "SchemaRegistryEntry|SCHEMA_INCOMPATIBLE|descriptive snapshot|unsupported" SPEC.md`
+
+Expected: matching lines for the new schema registry contract language.
+
+**Step 3: Confirm the spec file remains unstaged**
+
+Run: `git status --short`
+
+Expected: `SPEC.md` remains untracked or unstaged per repo rules.
+
+### Task 1: Add Shared Schema Registry Contracts And Serializer Guards
+
+**Files:**
+
+- Create: `packages/shared/src/lib/contracts/schema.ts`
+- Create: `packages/shared/src/lib/contracts/schema.test.ts`
+- Modify: `packages/shared/src/index.ts`
+
+**Step 1: Write failing shared tests for the public schema registry contract**
+
+Cover:
+
+- `SchemaRegistryEntry` validation
+- `PUT /schema` request payload validation
+- serializer rejection of unsupported features
+- deterministic `INVALID_INPUT` diagnostics for unsupported/unserializable paths
+
+**Step 2: Run the new shared contract test to verify it fails**
+
+Run: `bun test packages/shared/src/lib/contracts/schema.test.ts`
+
+Expected: FAIL because the shared schema registry contract does not exist yet.
+
+**Step 3: Implement the minimal shared contract surface**
+
+In `schema.ts` add:
+
+- JSON-ish value helpers/types for registry payloads
+- validators/parsers for:
+  - schema sync request body
+  - schema registry entry
+  - optional extracted components payload
+- descriptive snapshot serializer guards that reject unsupported features with
+  actionable `RuntimeError({ code: "INVALID_INPUT" })`
+
+**Step 4: Export the new shared contract**
+
+Update `packages/shared/src/index.ts` to export `./lib/contracts/schema.js`.
+
+**Step 5: Re-run the shared contract test**
+
+Run: `bun test packages/shared/src/lib/contracts/schema.test.ts`
+
+Expected: PASS.
+
+**Step 6: Typecheck shared**
+
+Run: `bun x tsc -p packages/shared/tsconfig.lib.json --noEmit`
+
+Expected: PASS.
+
+**Step 7: Commit**
+
+```bash
+git add packages/shared/src/lib/contracts/schema.ts packages/shared/src/lib/contracts/schema.test.ts packages/shared/src/index.ts
+git commit -m "feat(shared): add schema registry contracts"
+```
+
+### Task 2: Add Schema Registry Tables, Migration, And DB Contract Coverage
+
+**Files:**
+
+- Modify: `apps/server/src/lib/db/schema.ts`
+- Modify: `apps/server/src/lib/db/schema.contract.test.ts`
+- Create: `apps/server/drizzle/0007_<name>.sql`
+- Modify: `apps/server/drizzle/meta/_journal.json`
+- Create or Modify: `apps/server/drizzle/meta/0007_snapshot.json`
+
+**Step 1: Extend the DB contract test with failing expectations**
+
+Add assertions for:
+
+- `schema_syncs` columns, uniques, FK, indexes
+- `schema_registry_entries` columns, uniques, FK, indexes
+
+**Step 2: Run the DB contract test to verify it fails**
+
+Run: `bun test apps/server/src/lib/db/schema.contract.test.ts`
+
+Expected: FAIL because the new tables/migration artifacts do not exist.
+
+**Step 3: Add the new Drizzle table definitions**
+
+In `schema.ts`, add:
+
+- `schemaSyncs`
+- `schemaRegistryEntries`
+
+Follow the existing environment-scoped pattern:
+
+- `projectId`
+- `environmentId`
+- composite FK back to `environments`
+- unique constraints for latest sync row and per-type row uniqueness
+
+**Step 4: Add the new migration artifacts**
+
+Create the next migration after `0006_concerned_logan.sql` and update the
+journal/meta snapshot so the contract test sees the new schema.
+
+**Step 5: Re-run the DB contract test**
+
+Run: `bun test apps/server/src/lib/db/schema.contract.test.ts`
+
+Expected: PASS.
+
+**Step 6: Typecheck server DB code**
+
+Run: `bun x tsc -p apps/server/tsconfig.lib.json --noEmit`
+
+Expected: PASS.
+
+**Step 7: Commit**
+
+```bash
+git add apps/server/src/lib/db/schema.ts apps/server/src/lib/db/schema.contract.test.ts apps/server/drizzle
+git commit -m "feat(server): add schema registry tables"
+```
+
+### Task 3: Add Registry Persistence And Compatibility Logic
+
+**Files:**
+
+- Create: `apps/server/src/lib/schema-api.ts`
+- Create: `apps/server/src/lib/schema-api.test.ts`
+- Reference: `apps/server/src/lib/content-api.ts`
+
+**Step 1: Write failing schema API/store tests for the core success path**
+
+Cover:
+
+- `PUT /api/v1/schema` persists one sync row plus derived type rows
+- `GET /api/v1/schema` returns one entry per type
+- `GET /api/v1/schema/:type` returns the correct type
+
+Use the same testing style as `content-api.test.ts`.
+
+**Step 2: Run the new server test to verify it fails**
+
+Run: `bun test apps/server/src/lib/schema-api.test.ts`
+
+Expected: FAIL because the route module/store does not exist yet.
+
+**Step 3: Implement the registry store and route module**
+
+In `schema-api.ts`:
+
+- add a DB-backed registry store abstraction
+- parse target scope from request
+- validate `PUT` request payload with the shared contract
+- transactionally:
+  - resolve scope ids without auto-creating project/environment
+  - upsert the environment-level sync row
+  - replace derived per-type rows for that environment
+- shape success responses as `{ data: ... }`
+
+**Step 4: Implement structural compatibility checks**
+
+Still in `schema-api.ts`, add compatibility logic for `409 SCHEMA_INCOMPATIBLE`
+covering the approved coarse rules:
+
+- deleting a type that still has documents
+- incompatible localization changes
+- removing a supported locale that still has documents
+- introducing required fields against existing documents
+- clearly breaking coarse field-kind changes
+
+Keep anything unsupported or unserializable in the `400 INVALID_INPUT` path.
+
+**Step 5: Re-run the schema API test**
+
+Run: `bun test apps/server/src/lib/schema-api.test.ts`
+
+Expected: PASS for the initial success-path and compatibility coverage.
+
+**Step 6: Commit**
+
+```bash
+git add apps/server/src/lib/schema-api.ts apps/server/src/lib/schema-api.test.ts
+git commit -m "feat(server): add schema registry API"
+```
+
+### Task 4: Wire Schema Routes Into Server Runtime And Auth
+
+**Files:**
+
+- Modify: `apps/server/src/lib/runtime-with-modules.ts`
+- Modify: `apps/server/src/lib/auth.ts`
+- Modify: `apps/server/src/lib/rbac.ts`
+- Modify: `apps/server/src/lib/auth.test.ts`
+- Modify: `apps/server/src/lib/target-routing-guard.test.ts`
+
+**Step 1: Add failing auth/routing tests**
+
+Cover:
+
+- missing target routing for `/api/v1/schema`
+- mismatched target routing
+- API key `schema:read` required for `GET`
+- API key `schema:write` required for `PUT`
+- session-based RBAC gating for schema routes
+
+**Step 2: Run the affected auth/routing tests to verify they fail**
+
+Run:
+
+- `bun test apps/server/src/lib/auth.test.ts`
+- `bun test apps/server/src/lib/target-routing-guard.test.ts`
+
+Expected: FAIL because schema routes are not yet mounted into auth coverage or
+RBAC action mapping.
+
+**Step 3: Extend RBAC action mapping for schema routes**
+
+Update `rbac.ts` and `auth.ts` so sessions can be authorized for:
+
+- `schema:read`
+- `schema:write`
+
+Preserve deny-by-default behavior.
+
+**Step 4: Mount the schema API routes in server bootstrap**
+
+Update `runtime-with-modules.ts` to mount the new schema route module with the
+same `authorizeRequest` surface used by content routes.
+
+**Step 5: Re-run auth and routing tests**
+
+Run:
+
+- `bun test apps/server/src/lib/auth.test.ts`
+- `bun test apps/server/src/lib/target-routing-guard.test.ts`
+
+Expected: PASS.
+
+**Step 6: Commit**
+
+```bash
+git add apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/auth.ts apps/server/src/lib/rbac.ts apps/server/src/lib/auth.test.ts apps/server/src/lib/target-routing-guard.test.ts

+- schema registry endpoint behavior
+- latest-state sync model
+- descriptive snapshot limitation
+- unsupported feature rejection
+- `400 INVALID_INPUT` vs `409 SCHEMA_INCOMPATIBLE`
+- registry-only writes during schema sync
+
+Add short code comments in `schema-api.ts` for non-obvious compatibility and
+serialization logic.
+
+**Step 2: Format the changed docs/source files**
+
+Run: `bun x prettier --write packages/shared/README.md apps/cli/README.md apps/server/src/lib/schema-api.ts`
+
+Expected: files rewritten or confirmed already formatted.
+
+**Step 3: Commit**
+
+```bash
+git add packages/shared/README.md apps/cli/README.md apps/server/src/lib/schema-api.ts
+git commit -m "docs: describe schema registry limits"

+# CMS-19 Project Boundaries Design
+
+## Scope
+
+Implement CMS-19 strictly within the existing server/runtime surface:
+
+- keep project identity backed by `projects.slug`
+- preserve nullable `organization_id`
+- centralize project/environment scope resolution for server stores
+- prove cross-project isolation for content, schema, and environment operations
+
+Out of scope:
+
+- project CRUD endpoints
+- auth or RBAC behavior changes
+- Studio project switcher work
+- new media or webhook runtime APIs
+
+## Approved Approach
+
+Use an internal repository-style refactor, not a public API expansion.
+
+The existing project/environment lookup and provisioning logic is currently split
+between:
+
+- `apps/server/src/lib/project-provisioning.ts`
+- `apps/server/src/lib/content-api.ts`
+- `apps/server/src/lib/schema-api.ts`
+- `apps/server/src/lib/environments-api.ts`
+
+CMS-19 will consolidate that logic into one server-owned module so each store
+resolves scope through the same path.
+
+## Architecture
+
+The internal project repository owns:
+
+- `findProjectBySlug`
+- `ensureProjectProvisioned`
+- `resolveProjectEnvironmentScope(project, environment, { createIfMissing })`
+- `requireProjectEnvironmentScope(...)`
+- `requireEnvironmentInProject(project, environmentId)`
+
+The route/store layers keep responsibility for mapping repository results into
+endpoint-specific `RuntimeError` responses.
+
+## Data Flow
+
+### Content store
+
+- replace the store-local `resolveScopeIds` helper with repository-backed scope
+  resolution
+- keep document reads and writes scoped by `(projectId, environmentId)`
+- keep wrong-project `documentId` access returning `NOT_FOUND`
+
+### Schema store
+
+- reuse the same repository helper for project/environment resolution
+- keep schema list/get/sync fully isolated to the resolved scope
+
+### Environment store
+
+- keep project-routed list/create/delete contracts unchanged
+- use the repository for provisioning and environment ownership checks
+
+## Provisioning Rules
+
+Preserve current behavior where it already exists:
+
+- environment creation may provision the project row and default `production`
+  environment transactionally
+- content creation keeps its current repository-backed scope resolution behavior
+
+CMS-19 should not broaden or normalize provisioning semantics beyond the current
+contract surface.
+
+## Error Handling
+
+Public error contracts remain unchanged.
+

+# CMS-19 Project Boundaries Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Centralize project/environment scope resolution in the server and verify cross-project isolation for CMS content, schema, and environment flows.
+
+**Architecture:** Expand the existing project provisioning module into a small internal repository that owns project lookup, default provisioning, and project/environment scope resolution. Refactor the content, schema, and environment stores to depend on that shared module while keeping public routes, payloads, and error contracts unchanged.
+
+**Tech Stack:** Bun, TypeScript, Elysia route handlers, Drizzle ORM, postgres.js, node:test, Nx
+
+---
+
+### Task 1: Build the Internal Project Repository
+
+**Files:**
+
+- Modify: `apps/server/src/lib/project-provisioning.ts`
+- Create: `apps/server/src/lib/project-provisioning.test.ts`
+
+**Step 1: Write the failing test**
+
+```ts
+test("project provisioning resolves project/environment scope within one project", async () => {
+  const result = await resolveProjectEnvironmentScope(db, {
+    project: "marketing-site",
+    environment: "production",
+    createIfMissing: true,
+  });
+
+  assert.equal(result?.project.slug, "marketing-site");
+  assert.equal(result?.environment.name, "production");
+});
+
+test("project provisioning rejects environment ownership from another project", async () => {
+  const result = await requireEnvironmentInProject(db, {
+    project: "marketing-site",
+    environmentId: docsEnvironment.id,
+  });
+
+  assert.equal(result, undefined);
+});
+```
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test apps/server/src/lib/project-provisioning.test.ts`
+Expected: FAIL because the new repository helpers and test file do not exist yet.
+
+**Step 3: Write minimal implementation**
+
+```ts
+export async function resolveProjectEnvironmentScope(
+  db: DrizzleDatabase,
+  input: {
+    project: string;
+    environment: string;
+    createIfMissing?: boolean;
+  },
+) {
+  const project = input.createIfMissing
+    ? await ensureProjectProvisioned(db, { project: input.project })
+    : await findProjectBySlug(db, input.project);
+
+  // Load the concrete project row, then the environment row scoped by projectId.
+  // Return typed records or undefined; do not throw route-specific RuntimeErrors.
+}
+
+export async function requireEnvironmentInProject(
+  db: DrizzleDatabase,
+  input: { project: string; environmentId: string },
+) {
+  // Resolve the project by slug, then load environments.id scoped by projectId.
+}
+```
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test apps/server/src/lib/project-provisioning.test.ts`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/project-provisioning.ts apps/server/src/lib/project-provisioning.test.ts
+git commit -m "feat(server): add project scope repository helpers"
+```
+
+### Task 2: Refactor Content Store to Use Shared Scope Resolution
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api.ts`

+      },
+    }),
+  );
+
+  assert.equal(response.status, 404);
+});
+```
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts`
+Expected: FAIL because the database-backed content test does not exist yet or because content scope resolution is still duplicated.
+
+**Step 3: Write minimal implementation**
+
+```ts
+const scopeIds = await resolveProjectEnvironmentScope(db, {
+  project: scope.project,
+  environment: scope.environment,
+  createIfMissing,
+});
+
+if (!scopeIds) {
+  return undefined;
+}
+
+// Keep all document queries filtered by both projectId and environmentId.
+```
+
+Add one wrong-project write-path assertion as well, preferably `PUT` or `DELETE`,
+to prove scoped mutation denial returns `NOT_FOUND`.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts`
+Expected: PASS

+# CMS-20 Locale Translation Groups Design
+
+## Scope
+
+Implement CMS-20 inside the existing server content API surface.
+
+In scope:
+
+- add translation-group creation semantics to `POST /api/v1/content`
+- preserve the existing response shape (`translationGroupId` is already exposed)
+- enforce project/environment scoping for variant creation
+- add deterministic conflict handling for duplicate locales within a translation
+  group
+- document the new operator-facing create contract in the server package docs
+
+Out of scope:
+
+- new routes for locale variants
+- Studio locale switcher UX and optional prefill flow (CMS-63)
+- clone/promote remapping behavior (later environment tasks)
+- full schema-aware validation for every content write path
+- migrations or table/index changes; the database already has the required
+  `translation_group_id` column and uniqueness index from CMS-11/CMS-12
+
+## Spec Delta Summary
+
+Confirmed contract delta for this task:
+
+- `POST /api/v1/content` gains optional `sourceDocumentId`
+- omitted `sourceDocumentId` keeps existing "create a brand new logical
+  document" semantics
+- provided `sourceDocumentId` creates a new locale variant in the same
+  translation group as the source document
+- `sourceDocumentId` is valid for any non-deleted source document in the routed
+  `project` and `environment`
+- the server derives `translation_group_id` from the source document; callers do
+  not send raw `translationGroupId`
+
+This closes the gap between:
+
+- the data model requirement that localized variants share a
+  `translation_group_id`
+- the Studio UX requirement that users can switch to an untranslated locale and
+  create the variant
+- the canonical content create contract, which previously had no way to express
+  "create a sibling translation of this existing document"
+
+## Approved Approach
+
+Keep one create endpoint and add an explicit variant-creation mode.
+
+`POST /api/v1/content` now has two behaviors:
+
+1. **New logical document**
+   - request omits `sourceDocumentId`
+   - server generates a new `document_id`
+   - server generates a new `translation_group_id`
+
+2. **New locale variant**
+   - request includes `sourceDocumentId`
+   - server resolves the source document within the routed scope
+   - server generates a new `document_id`
+   - server reuses the source document's `translation_group_id`
+
+This keeps the route surface minimal while making variant creation explicit and
+safe. The request does not accept raw `translationGroupId`, because that would
+let callers bypass scope and type checks.
+
+## Request Contract
+
+`POST /api/v1/content` continues to accept:
+
+- `path`
+- `type`
+- `locale`
+- `format`
+- `frontmatter`
+- `body`
+- optional actor fields
+
+New optional field:
+
+- `sourceDocumentId`
+
+Rules:
+
+- callers must still send the full draft payload; the server does not
+  auto-prefill content from the source document
+- Studio can implement optional prefill client-side later by reading the source
+  draft/published document and submitting copied content when desired
+- `path` remains explicit input; the server does not infer translation groups
+  from `path`
+
+## Validation and Data Flow
+
+### Variant creation
+
+When `sourceDocumentId` is present:
+
+1. resolve the source document inside the routed `project` and `environment`
+2. reject missing or soft-deleted sources with `NOT_FOUND`
+3. require request `type` to match the source document's `schema_type`
+4. resolve the source type's schema registry entry in the same scope
+5. reject variant creation for non-localized schema types with `INVALID_INPUT`
+6. validate that the requested locale does not already exist in the source
+   translation group for a non-deleted document
+7. create the new row with:
+   - fresh `document_id`
+   - inherited `translation_group_id`
+   - caller-provided `path`, `locale`, `format`, `frontmatter`, and `body`
+
+### Locale policy enforcement
+
+CMS-20 adds schema-backed locale validation only where it is required for the
+new translation-group behavior.
+
+- in variant-creation mode, the server uses scoped schema registry data to
+  verify that the type is localized and that the requested locale is allowed for
+  the environment's synced locale configuration
+- CMS-20 does **not** broaden content writes into full schema-aware validation
+  for every create/update path; that stays aligned with later content-core work
+
+This keeps the task scoped while preventing invalid translation-group writes.
+
+## Error Handling
+
+Existing deterministic errors remain unchanged where they still apply:
+
+- `CONTENT_PATH_CONFLICT` (`409`) remains the `(project, environment, locale,
+path)` uniqueness error
+- `NOT_FOUND` (`404`) remains the missing/out-of-scope/soft-deleted source
+  error for `sourceDocumentId`
+- `INVALID_INPUT` (`400`) covers malformed or invalid variant requests, such as:
+  - `sourceDocumentId` type mismatch
+  - `sourceDocumentId` used for a non-localized type
+  - locale rejected by the synced supported-locale set
+
+New deterministic conflict:
+
+- `TRANSLATION_VARIANT_CONFLICT` (`409`) when the translation group already has
+  a non-deleted document in the requested locale
+
+The DB-backed store should map the existing unique index on
+`(project_id, environment_id, translation_group_id, locale)` to
+`TRANSLATION_VARIANT_CONFLICT` so race conditions still return the same public
+error code.
+
+## Testing
+
+Add coverage in `apps/server/src/lib/content-api.test.ts` for:
+
+- in-memory create flow reusing `translationGroupId` when `sourceDocumentId` is
+  provided
+- duplicate locale rejection within one translation group
+- DB-backed variant creation reusing `translationGroupId` while generating a new
+  `documentId`
+- rejection of `sourceDocumentId` from another project/environment
+- rejection of soft-deleted sources
+- rejection of non-localized source types
+- rejection of unsupported locales for localized types
+
+Verification commands:
+
+- `bun test apps/server/src/lib/content-api.test.ts`
+- `bun run format:check`
+- `bun run check`
+
+## Documentation
+
+Document the new create contract in `apps/server/README.md` at the point of
+use:
+
+- `POST /api/v1/content` supports optional `sourceDocumentId`
+- omitted `sourceDocumentId` creates a new logical document
+- provided `sourceDocumentId` creates a locale variant in the source
+  translation group
+- duplicate locale conflicts return `TRANSLATION_VARIANT_CONFLICT`
+
+## Repo Policy Note

+This design file is intentionally stored in `docs/plans/` as a local planning
+artifact and should remain untracked per the repository instructions in
+`AGENTS.md`.

+# CMS-20 Locale Translation Groups Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Extend the server content create endpoint so locale variants can be created in the same translation group using `sourceDocumentId`, with deterministic validation and conflict handling.
+
+**Architecture:** Keep the existing `POST /api/v1/content` route and add an explicit variant-creation mode inside `apps/server/src/lib/content-api.ts`. Reuse the existing documents table and unique translation-locale index, add scoped source-document and schema-registry lookups in the DB-backed store, and cover the new behavior through in-memory and DB-backed content API tests.
+
+**Tech Stack:** Bun, TypeScript, Elysia route handlers, Drizzle ORM, postgres.js, node:test, Nx
+

+
+### Task 1: Add the Variant-Creation Contract to the Route and In-Memory Store

+# CMS-23 + CMS-24 Restore and Version History Design
+
+## Scope
+
+Implement the bundled `CMS-23` and `CMS-24` server-side content behaviors
+inside the existing content API surface in `apps/server`.
+
+In scope:
+
+- add exact-undelete trash restore to `POST /api/v1/content/:documentId/restore`
+- add immutable version history read endpoints
+- add historical version restore to
+  `POST /api/v1/content/:documentId/versions/:version/restore`
+- preserve project/environment scoping, deterministic conflict handling, and
+  append-only version history guarantees
+- document the new API contract at the point of use in the server README
+
+Out of scope:
+
+- Studio trash/version-history UI
+- CLI commands for restore or history
+- schema-aware field validation beyond the current content write contract
+- collaboration merge semantics
+- new tables or indexes; the existing `documents` and `document_versions`
+  schema already support the required behavior
+
+## Spec Delta Summary
+
+Confirmed contract delta for this bundled implementation:
+
+- `POST /api/v1/content/:documentId/restore` is an exact undelete of the
+  current head row only
+- trash restore does **not** accept `targetStatus`
+- trash restore does **not** append a new `document_versions` row
+- trash restore preserves the current head state, including any existing
+  `publishedVersion`, and only clears `isDeleted`
+- `POST /api/v1/content/:documentId/versions/:version/restore` is the only
+  restore flow that accepts `targetStatus=draft|published`
+- `targetStatus=draft` updates mutable head content only
+- `targetStatus=published` appends a fresh immutable version row at HEAD and
+  updates `publishedVersion`
+
+This resolves the ambiguity between the current `SPEC-003` prose and endpoint
+table by keeping plain trash restore as undelete-only and leaving publish-style
+restoration on the version-restore endpoint.
+
+## Approved Approach
+
+Keep the work inside the existing content API module and extend the current
+store abstraction.
+
+The implementation will:
+
+1. extend `ContentStore` with `restore`, `listVersions`, `getVersion`, and
+   `restoreVersion`
+2. keep in-memory and DB-backed stores aligned so HTTP tests exercise the same
+   public contract in both modes
+3. reuse the existing publish flow semantics for restore-to-published so the
+   version history remains linear and append-only
+4. centralize path-conflict handling so both trash restore and version restore
+   return the same deterministic `CONTENT_PATH_CONFLICT` error shape
+
+This keeps the task scoped to the existing server boundary while preserving the
+behavioral guarantees already established by the content API.
+
+## Request Contract
+
+### `POST /api/v1/content/:documentId/restore`
+
+- no request body fields are required
+- exact undelete of the current head row
+- clears `isDeleted`
+- preserves current head content and `publishedVersion`
+- does not append version history
+
+### `GET /api/v1/content/:documentId/versions`
+
+- returns immutable publish history for the routed document
+- response items are version summaries derived from `document_versions`
+
+### `GET /api/v1/content/:documentId/versions/:version`
+
+- returns one immutable snapshot from `document_versions`
+
+### `POST /api/v1/content/:documentId/versions/:version/restore`
+
+- accepts optional `targetStatus` enum: `draft` or `published`
+- default is `draft`
+- `draft` updates the mutable head from the chosen immutable snapshot and sets
+  `hasUnpublishedChanges = true`
+- `published` updates the mutable head from the chosen immutable snapshot,
+  appends a new immutable publish row, and updates `publishedVersion`
+
+## Validation and Data Flow
+
+### Trash restore
+
+When restoring a soft-deleted document:
+
+1. resolve the document within the routed `project` and `environment`
+2. reject missing documents with `NOT_FOUND`
+3. reject already-active documents by returning the current active head
+   semantics only if explicitly supported; for this task, only deleted documents
+   are restorable
+4. check whether another active document already occupies the same
+   `(project, environment, locale, path)` tuple
+5. if no conflict exists, clear `isDeleted` and return the restored head
+
+### Version history reads
+
+1. resolve the document within the routed scope
+2. reject missing or soft-deleted targets with `NOT_FOUND`
+3. read immutable rows from `document_versions` for that `documentId`
+4. return descending version order for list responses
+
+### Version restore
+
+When restoring a historical version:
+
+1. resolve the head document within the routed scope
+2. resolve the requested immutable version row for the same `documentId`
+3. reject malformed versions with `INVALID_INPUT`
+4. reject missing snapshots with `NOT_FOUND`
+5. check active path uniqueness against the snapshot path and locale
+6. update the mutable head from the snapshot
+7. for `targetStatus=draft`, set `hasUnpublishedChanges = true` and do not
+   append a version row
+8. for `targetStatus=published`, append a fresh immutable version row and set
+   `publishedVersion` to the new HEAD version number
+
+## Error Handling
+
+Deterministic errors for the bundled work:
+
+- `INVALID_INPUT` (`400`)
+  - malformed `version` path parameter
+  - invalid `targetStatus`
+- `NOT_FOUND` (`404`)
+  - document missing in the routed scope
+  - requested immutable version missing for the document
+- `CONTENT_PATH_CONFLICT` (`409`)
+  - trash restore or version restore would reactivate/update the head into an
+    active `(project, environment, locale, path)` collision
+
+Conflict details should include:
+
+- `path`
+- `locale`
+- `conflictDocumentId` when available
+
+## Testing
+
+Add coverage in `apps/server/src/lib/content-api.test.ts` for:
+
+- in-memory trash restore exact undelete
+- in-memory trash restore conflict handling
+- in-memory version history listing and single-version fetch
+- in-memory draft version restore
+- in-memory published version restore appending a fresh HEAD version
+- DB-backed trash restore conflict handling
+- DB-backed published version restore preserving linear append-only history
+
+Verification commands:
+
+- `bun test apps/server/src/lib/content-api.test.ts`
+- `bun run format:check`
+- `bun run check`
+
+## Documentation
+
+Document the new content contracts in `apps/server/README.md`:
+
+- trash restore is exact undelete of the current head
+- version history endpoints expose immutable publish snapshots
+- version restore supports `targetStatus=draft|published`
+- restore conflicts return `CONTENT_PATH_CONFLICT`
+

+# CMS-23 + CMS-24 Restore and Version History Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add exact trash restore, immutable version-history reads, and
+historical version restore semantics to the server content API.
+
+**Architecture:** Extend the existing content store contract inside
+`apps/server/src/lib/content-api.ts` so the in-memory and DB-backed stores both
+implement the same restore/version behaviors. Keep route orchestration in the
+current content API module, reuse existing publish semantics for
+restore-to-published, and cover the new behavior primarily through
+HTTP-level tests in `apps/server/src/lib/content-api.test.ts`.
+
+**Tech Stack:** Bun, TypeScript, Elysia route handlers, Drizzle ORM,
+postgres.js, node:test, Nx
+
+---
+
+### Task 1: Add Failing Tests for Trash Restore and Version History
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Write the failing tests**
+
+```ts
+test("content API restore undeletes the current head without appending a version", async () => {
+  const handler = createHandler();
+
+  // Create, publish, soft-delete, restore, then assert:
+  // - restore returns 200
+  // - isDeleted is false
+  // - publishedVersion is unchanged
+  // - version list length is still 1
+});
+
+test("content API returns version history summaries and individual snapshots", async () => {
+  const handler = createHandler();
+
+  // Create, publish twice, then assert GET /versions and GET /versions/:version.
+});
+
+test("content API restores a historical version to draft state by default", async () => {
+  const handler = createHandler();
+
+  // Publish v1, update + publish v2, restore v1 with no targetStatus, then
+  // assert head content matches v1 and history length remains 2.
+});
+
+test("content API restores a historical version to published state when requested", async () => {
+  const handler = createHandler();
+
+  // Publish v1, publish v2, restore v1 with targetStatus=published, then
+  // assert a new version 3 exists and publishedVersion is 3.
+});
+```
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts`
+Expected: FAIL because the restore and version-history routes do not exist yet.
+
+**Step 3: Write minimal implementation**
+
+```ts
+type ContentVersionSummary = {
+  version: number;
+  path: string;
+  locale: string;
+  type: string;
+  format: ContentFormat;
+  publishedAt: string;
+  publishedBy: string;
+  changeSummary?: string;
+};
+
+type ContentVersionDocument = ContentVersionSummary & {
+  documentId: string;
+  translationGroupId: string;
+  frontmatter: Record<string, unknown>;
+  body: string;
+};
+
+type ContentRestoreVersionPayload = {
+  targetStatus?: string;
+  actorId?: unknown;
+  changeSummary?: unknown;
+  change_summary?: unknown;
+};
+```
+
+Extend the in-memory store and route handlers just enough to make the new tests
+pass before touching the DB-backed parity cases.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts`
+Expected: PASS for the new in-memory restore/version coverage.
+
+**Step 5: Commit**
+
+```bash

+
+### Task 2: Add DB-Backed Restore and Version-Restore Behavior
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api.ts`
+- Modify: `apps/server/src/lib/content-api.test.ts`

+**Step 1: Write the failing DB-backed tests**
+
+```ts

+  "content API DB restore returns CONTENT_PATH_CONFLICT when undelete collides with an active path",
+  async () => {
+    // Create doc A, soft-delete it, create doc B with the same path/locale,

+    // Publish v1, publish v2, restore v1 to published, then assert:
+    // - publishedVersion is 3
+    // - document_versions now has 3 rows
+    // - version 3 body/frontmatter/path match v1
+  },
+);
+```
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts`
+Expected: FAIL because the DB-backed store does not yet implement restore or
+version-history operations.
+
+**Step 3: Write minimal implementation**
+
+```ts
+async restore(scope, documentId) {
+  // Resolve scope ids and current document row.
+  // Reject missing rows with NOT_FOUND.
+  // Check active path uniqueness excluding the current document id.
+  // Clear isDeleted and return the updated head row.
+}
+
+async restoreVersion(scope, documentId, version, input) {
+  // Resolve document + immutable version snapshot in one transaction.
+  // Check path uniqueness against the snapshot path/locale.
+  // Update the head row from the snapshot.
+  // If targetStatus === "published", append a fresh version row and set
+  // publishedVersion to the new version number.
+}
+```
+
+Map unique/path conflicts to `CONTENT_PATH_CONFLICT` with consistent details in
+both restore flows.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts`
+Expected: PASS for the new DB-backed restore/version tests.
+
+**Step 5: Commit**

+git commit -m "feat(server): add DB-backed restore semantics"
+```
+
+### Task 3: Document the Operator-Facing Contract and Run Verification
+
+**Files:**
+
+- Modify: `apps/server/README.md`
+
+**Step 1: Write the failing doc expectation**
+
+```md
+- `POST /api/v1/content/:documentId/restore` undeletes the current head only.
+- `GET /api/v1/content/:documentId/versions` lists immutable publish history.
+- `GET /api/v1/content/:documentId/versions/:version` returns one immutable snapshot.
+- `POST /api/v1/content/:documentId/versions/:version/restore` restores a snapshot to draft or published state.
+```
+
+**Step 2: Run check to verify docs are missing**
+
+Run: `rg -n "documentId/restore|versions/:version/restore" apps/server/README.md`
+Expected: missing or incomplete entries for the new restore/version contract.
+
+**Step 3: Write minimal implementation**
+
+Add a short API contract section in `apps/server/README.md` describing the new
+endpoints, the exact-undelete trash restore behavior, and the `CONTENT_PATH_CONFLICT`
+restore error.
+
+**Step 4: Run verification**

+# CMS-38 CSRF Enforcement Design
+
+Date: 2026-03-12
+Status: approved in chat, local planning artifact only
+
+## Goal
+
+Implement CSRF enforcement for session-authenticated, state-changing Studio API requests without changing API-key behavior.
+
+## Source Of Truth
+
+- Roadmap task: `CMS-38` in `ROADMAP_TASKS.md`
+- Owning auth spec: `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
+- Related endpoint specs:
+  - `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
+  - `docs/specs/SPEC-004-schema-system-and-sync.md`
+  - `docs/specs/SPEC-009-i18n-and-environments.md`
+  - `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+
+## Approved Spec Delta
+
+Add a concrete CSRF contract to `SPEC-005`:
+
+- Session-authenticated `POST`, `PUT`, `PATCH`, and `DELETE` requests require CSRF validation.
+- The server issues a readable cookie named `mdcms_csrf`.
+- The client must echo the same value in the `x-mdcms-csrf-token` request header.
+- A state-changing session request is accepted only when:
+  - the Studio session cookie is valid,
+  - the `mdcms_csrf` cookie is present,
+  - the `x-mdcms-csrf-token` header is present,
+  - the cookie value and header value match.
+- API-key authenticated requests are exempt from CSRF enforcement.
+- Read-only requests (`GET`, `HEAD`, `OPTIONS`) are exempt.
+- Public auth routes are exempt:
+  - `/api/v1/auth/login`
+  - `/api/v1/auth/sign-up/email`
+  - `/api/v1/auth/sign-in/email`
+  - `/api/v1/auth/cli/login/*`
+- CSRF failures return deterministic authz semantics:
+  - status `403`
+  - code `FORBIDDEN`
+  - message `Valid CSRF token is required for session-authenticated state-changing requests.`
+
+## Server Design
+
+Keep CSRF enforcement server-side in `apps/server/src/lib/auth.ts`, with a shared helper used by first-party mutation handlers.
+
+### Token Lifecycle
+
+- Mint a random CSRF token on successful `POST /api/v1/auth/login`.
+- Also mint and return the token on successful session bootstrap reads:
+  - `GET /api/v1/auth/session`
+  - `GET /api/v1/auth/get-session`
+- Clear the CSRF cookie on:
+  - `POST /api/v1/auth/logout`
+  - `POST /api/v1/auth/sign-out`
+
+This lets the Studio recover a token when the browser already has a valid session cookie.
+
+### Enforcement Rule
+
+The shared helper should:
+
+1. Skip CSRF validation when the request is not state-changing.
+2. Skip CSRF validation when the request authenticates with `Authorization: Bearer ...` because that is an API-key flow, not a cookie-backed Studio session.
+3. If no bearer token is present, check whether a valid session exists.
+4. If there is a valid session and the request is state-changing, require matching `mdcms_csrf` cookie and `x-mdcms-csrf-token` header values.
+5. If there is no valid session, do not transform the failure; let the existing auth path return `401`.
+
+This preserves current `401` vs `403` behavior and keeps the scope explicit.
+
+## Endpoint Coverage
+
+Apply the guard only to first-party state-changing routes that can be session-authenticated:
+
+- Auth mutation routes in `apps/server/src/lib/auth.ts`
+  - `POST /api/v1/auth/logout`
+  - `POST /api/v1/auth/api-keys`
+  - `POST /api/v1/auth/api-keys/:keyId/revoke`
+  - `POST /api/v1/auth/users/:userId/sessions/revoke-all`
+- Content mutations in `apps/server/src/lib/content-api/routes.ts`
+- Schema sync mutation in `apps/server/src/lib/schema-api.ts`
+- Environment mutations in `apps/server/src/lib/environments-api.ts`
+
+Do not apply the guard to:
+
+- login and sign-up routes
+- CLI browser-login routes
+- API-key self-revoke route
+- read-only routes
+
+## Testing Strategy
+
+Primary acceptance tests:
+
+- session mutation succeeds with matching CSRF cookie and header
+- session mutation fails when header is missing
+- session mutation fails when CSRF cookie is missing
+- session mutation fails when values mismatch
+- API-key mutation remains allowed without CSRF
+- login/session bootstrap routes emit `mdcms_csrf`
+- logout/sign-out clear `mdcms_csrf`
+
+Route-level regression coverage:
+
+- content mutation test in `apps/server/src/lib/content-api.test.ts`
+- schema sync test in `apps/server/src/lib/schema-api.test.ts`
+- environment mutation test in `apps/server/src/lib/environments-api.test.ts`
+
+## Documentation
+
+- Update `SPEC-005` with the concrete CSRF contract.
+- Add a short code comment near the shared guard in `auth.ts` explaining the session-only enforcement rule.
+
+## Validation
+
+Run from workspace root:
+
+- `bun test apps/server/src/lib/auth.test.ts`
+- `bun test apps/server/src/lib/content-api.test.ts`
+- `bun test apps/server/src/lib/schema-api.test.ts`
+- `bun test apps/server/src/lib/environments-api.test.ts`
+- `bun run format:check`
+- `bun run check`
+
+## Notes
+
+- `docs/plans/` is intentionally local-only in this repository and should remain untracked.

+# CMS-38 CSRF Enforcement Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Enforce CSRF on session-authenticated state-changing Studio API requests while keeping API-key mutation flows unchanged.
+
+**Architecture:** Add one shared CSRF utility layer in the server auth module, issue a readable CSRF cookie alongside session bootstrap responses, and invoke the guard from first-party mutation handlers that accept session auth. Keep failures deterministic and scoped to the endpoints defined in the auth, content, schema, and environment specs.
+
+**Tech Stack:** Bun, TypeScript, Elysia, better-auth, Drizzle, Bun test
+
+---
+
+### Task 1: Codify The Contract In The Owning Spec
+
+**Files:**
+
+- Modify: `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
+
+**Step 1: Add the normative CSRF contract text**
+
+Insert a short normative subsection under Session Security and update the auth endpoint table notes with:
+
+```md
+- Session-authenticated POST/PUT/PATCH/DELETE requests require CSRF validation.
+- The server sets a readable `mdcms_csrf` cookie.
+- Clients must echo that value in `x-mdcms-csrf-token`.
+- API-key requests are exempt.
+- CSRF failures return `FORBIDDEN` (`403`).
+```
+
+**Step 2: Verify the spec matches the approved design**
+
+Check these exact behaviors are present:
+
+- cookie name: `mdcms_csrf`
+- header name: `x-mdcms-csrf-token`
+- protected methods: `POST`, `PUT`, `PATCH`, `DELETE`
+- exemptions: read-only methods, API-key requests, login/sign-up/CLI login routes
+
+**Step 3: Commit the spec change separately if using commit checkpoints**
+
+```bash
+git add docs/specs/SPEC-005-auth-authorization-and-request-routing.md
+git commit -m "docs: define CSRF contract for Studio mutations"
+```
+
+### Task 2: Add Failing Auth-Level CSRF Tests
+
+**Files:**
+
+- Modify: `apps/server/src/lib/auth.test.ts`
+
+**Step 1: Add helpers for CSRF cookie extraction and header injection**
+
+Add small helpers near the existing auth test utilities:
+
+```ts
+function extractCookieValue(
+  setCookie: string,
+  name: string,
+): string | undefined {
+  return setCookie
+    .split(/,\s*/)
+    .flatMap((chunk) => chunk.split(";"))
+    .map((part) => part.trim())
+    .find((part) => part.startsWith(`${name}=`))
+    ?.slice(name.length + 1);
+}
+```
+
+**Step 2: Write failing tests for the approved contract**
+
+Add tests that assert:
+
+- login returns a `set-cookie` containing `mdcms_csrf=`
+- `GET /api/v1/auth/session` reissues `mdcms_csrf=`
+- `POST /api/v1/auth/api-keys` with session cookie but no CSRF header returns `403`
+- the same route with mismatched header returns `403`
+- the same route with matching cookie/header returns `200`
+- `POST /api/v1/auth/logout` clears `mdcms_csrf`
+
+Example request shape:
+
+```ts
+new Request("http://localhost/api/v1/auth/api-keys", {
+  method: "POST",
+  headers: {
+    "content-type": "application/json",
+    cookie: `${sessionCookie}; mdcms_csrf=${csrfToken}`,
+    "x-mdcms-csrf-token": csrfToken,
+  },
+  body: JSON.stringify(payload),
+});
+```
+
+**Step 3: Run the focused auth test file and confirm failure**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+
+Expected: FAIL on the new CSRF assertions because the server does not issue or enforce the token yet.
+
+**Step 4: Commit the red test stage if using TDD checkpoints**
+
+```bash
+git add apps/server/src/lib/auth.test.ts
+git commit -m "test(server): add CMS-38 auth csrf coverage"
+```
+
+### Task 3: Implement CSRF Utilities And Token Issuance
+
+**Files:**
+
+- Modify: `apps/server/src/lib/auth.ts`
+
+**Step 1: Add CSRF constants and cookie helpers**
+
+Add constants near the existing auth constants:
+
+```ts
+const CSRF_COOKIE_NAME = "mdcms_csrf";
+const CSRF_HEADER_NAME = "x-mdcms-csrf-token";
+```
+
+Add helpers for:
+
+- generating a token with `randomBytes`
+- serializing the readable CSRF cookie
+- serializing a clearing cookie
+- reading a named cookie from the request
+
+**Step 2: Add a shared enforcement helper**
+
+Create a helper with behavior like:
+
+```ts
+async function requireCsrfForSessionMutation(request: Request): Promise<void> {
+  if (!isStateChangingMethod(request.method)) return;
+  if (extractBearerToken(request.headers.get("authorization"))) return;
+
+  const session = await getSessionIfAvailable(request);
+  if (!session) return;
+
+  const cookieToken = readCookie(request, CSRF_COOKIE_NAME);
+  const headerToken = request.headers.get(CSRF_HEADER_NAME)?.trim();
+  if (!cookieToken || !headerToken || cookieToken !== headerToken) {
+    throw new RuntimeError({
+      code: "FORBIDDEN",
+      message:
+        "Valid CSRF token is required for session-authenticated state-changing requests.",
+      statusCode: 403,
+    });
+  }
+}
+```
+
+Include a short code comment explaining why API-key requests are exempt.
+
+**Step 3: Issue CSRF cookies on session bootstrap responses**
+
+Update:
+
+- `login()` to include a CSRF cookie alongside the session cookie
+- `/api/v1/auth/session` and `/api/v1/auth/get-session` responses to set `mdcms_csrf`
+- `logout()` to clear `mdcms_csrf`
+- `handleAuthRequest` sign-out path to clear `mdcms_csrf` if the route is `/api/v1/auth/sign-out`
+
+If multiple cookies are set in one response, preserve the session cookie and append the CSRF cookie in the same `set-cookie` header string format already used by the server.
+
+**Step 4: Re-run auth tests**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+
+Expected: auth-level CSRF tests now pass or narrow failures to downstream route coverage still awaiting integration.
+
+**Step 5: Commit the auth implementation**
+
+```bash
+git add apps/server/src/lib/auth.ts apps/server/src/lib/auth.test.ts
+git commit -m "feat(server): add session csrf token handling"
+```
+
+### Task 4: Enforce CSRF On Auth Mutation Routes
+
+**Files:**
+
+- Modify: `apps/server/src/lib/auth.ts`
+
+**Step 1: Call the shared CSRF guard at the top of protected auth mutations**
+
+Add `await options.authService.requireCsrfProtection(request)` or equivalent shared helper call before:
+
+- `POST /api/v1/auth/logout`
+- `POST /api/v1/auth/users/:userId/sessions/revoke-all`
+- `POST /api/v1/auth/api-keys`
+- `POST /api/v1/auth/api-keys/:keyId/revoke`
+
+Do not enforce the guard on:
+
+- `POST /api/v1/auth/login`
+- better-auth sign-up/sign-in
+- CLI login routes
+- `POST /api/v1/auth/api-keys/self/revoke`
+
+**Step 2: Run auth tests again**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+
+Expected: PASS
+
+**Step 3: Commit the route enforcement change**
+
+```bash
+git add apps/server/src/lib/auth.ts
+git commit -m "feat(server): enforce csrf on auth session mutations"
+```
+
+### Task 5: Enforce CSRF On Content Mutations
+
+**Files:**
+
+- Modify: `apps/server/src/lib/auth.ts`
+- Modify: `apps/server/src/lib/content-api/routes.ts`
+- Modify: `apps/server/src/lib/content-api/types.ts`
+- Modify: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Expose the CSRF guard through the existing route authorizer surface**
+
+Prefer the smallest change that avoids duplicating auth internals:
+
+- either extend the auth service with a dedicated `requireCsrfProtection(request)` method
+- or extend `MountContentApiRoutesOptions` with a separate `requireCsrf` callback
+
+Keep the route contract explicit rather than reaching into auth internals from content routes.
+
+**Step 2: Add failing content-route tests**
+
+Add tests for a representative session-backed mutation such as `POST /api/v1/content`:
+
+- missing CSRF header returns `403`
+- matching CSRF cookie/header returns `200`
+- API-key request still succeeds without CSRF when scopes allow it
+
+**Step 3: Wire the guard into all content mutations**
+
+Invoke the guard before authorization/store calls in:
+
+- `POST /api/v1/content`
+- `PUT /api/v1/content/:documentId`
+- `POST /api/v1/content/:documentId/publish`
+- `POST /api/v1/content/:documentId/unpublish`
+- `DELETE /api/v1/content/:documentId`
+- `POST /api/v1/content/:documentId/restore`
+- `POST /api/v1/content/:documentId/versions/:version/restore`
+
+**Step 4: Run the focused content test file**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts`
+
+Expected: PASS
+
+**Step 5: Commit the content enforcement**
+
+```bash
+git add apps/server/src/lib/auth.ts apps/server/src/lib/content-api/routes.ts apps/server/src/lib/content-api/types.ts apps/server/src/lib/content-api.test.ts
+git commit -m "feat(server): enforce csrf on content mutations"
+```
+
+### Task 6: Enforce CSRF On Schema And Environment Mutations
+
+**Files:**
+
+- Modify: `apps/server/src/lib/runtime-with-modules.ts`
+- Modify: `apps/server/src/lib/schema-api.ts`
+- Modify: `apps/server/src/lib/schema-api.test.ts`
+- Modify: `apps/server/src/lib/environments-api.ts`
+- Modify: `apps/server/src/lib/environments-api.test.ts`
+
+**Step 1: Extend the route mount options if needed**
+
+If schema/environment route mounts only receive authz callbacks today, add a parallel CSRF callback so they can opt into the shared guard without re-implementing auth logic.
+
+**Step 2: Add failing schema/environment tests**
+
+Add one representative session-backed mutation test per surface:
+
+- `PUT /api/v1/schema` without CSRF returns `403`
+- `POST /api/v1/environments` without CSRF returns `403`
+- matching CSRF cookie/header succeeds
+
+**Step 3: Implement route-level enforcement**
+
+Invoke the shared guard before the existing mutation logic in:
+
+- `PUT /api/v1/schema`
+- `POST /api/v1/environments`
+- `DELETE /api/v1/environments/:id`
+
+**Step 4: Run the focused test files**
+
+Run: `bun test apps/server/src/lib/schema-api.test.ts`
+Expected: PASS
+
+Run: `bun test apps/server/src/lib/environments-api.test.ts`
+Expected: PASS
+
+**Step 5: Commit the schema/environment enforcement**
+
+```bash
+git add apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/schema-api.ts apps/server/src/lib/schema-api.test.ts apps/server/src/lib/environments-api.ts apps/server/src/lib/environments-api.test.ts
+git commit -m "feat(server): enforce csrf on schema and environment mutations"
+```
+
+### Task 7: Final Verification And Hygiene
+
+**Files:**
+
+- Verify only task-scoped changes are staged
+
+**Step 1: Run the touched test files together**
+
+Run: `bun test apps/server/src/lib/auth.test.ts apps/server/src/lib/content-api.test.ts apps/server/src/lib/schema-api.test.ts apps/server/src/lib/environments-api.test.ts`
+
+Expected: PASS
+
+**Step 2: Run repository validation commands**
+
+Run: `bun run format:check`
+Expected: PASS
+
+Run: `bun run check`
+Expected: PASS
+
+**Step 3: Inspect git status**
+
+Run: `git status --short`
+
+Expected:
+
+- only task-scoped source/spec changes are tracked
+- `docs/plans/` remains untracked
+- local-only files from `AGENTS.md` stay unstaged
+
+**Step 4: Create the final task-scoped commit if needed**
+
+```bash
+git add apps/server/src/lib/auth.ts apps/server/src/lib/auth.test.ts apps/server/src/lib/content-api/routes.ts apps/server/src/lib/content-api/types.ts apps/server/src/lib/content-api.test.ts apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/schema-api.ts apps/server/src/lib/schema-api.test.ts apps/server/src/lib/environments-api.ts apps/server/src/lib/environments-api.test.ts docs/specs/SPEC-005-auth-authorization-and-request-routing.md

+# Content API Refactor Design
+
+## Scope
+
+Refactor `apps/server/src/lib/content-api.ts` into smaller internal modules
+without changing any behavior, public exports, route contracts, or existing
+test expectations.
+
+In scope:
+
+- keep `apps/server/src/lib/content-api.ts` as the stable public entrypoint
+- extract shared content API types into an internal module
+- extract parsing/routing helpers into an internal module
+- extract response and row conversion helpers into an internal module
+- extract the in-memory content store into its own module
+- extract the DB-backed content store into its own module
+- extract route mounting into its own module
+- preserve the current test suite as the regression guard
+
+Out of scope:
+
+- endpoint behavior changes
+- route path or payload changes
+- new tests for new behavior
+- cleanup refactors unrelated to file decomposition
+- broader server architecture changes
+
+## Spec Delta Summary
+
+There is no product-spec delta for this work. This is a no-behavior-change
+internal refactor of the current server implementation.
+
+The contract that must remain unchanged is the existing public surface exported
+by `apps/server/src/lib/content-api.ts`:
+
+- `createInMemoryContentStore`
+- `createDatabaseContentStore`
+- `mountContentApiRoutes`
+
+Acceptance for this refactor depends on preserving:
+
+- existing content API runtime behavior
+- existing request/response contracts
+- existing test outcomes
+
+## Approved Approach
+
+Use a thin facade entrypoint and move internals into
+`apps/server/src/lib/content-api/`.
+
+Target structure:
+
+- `content-api.ts`
+- `content-api/types.ts`
+- `content-api/parsing.ts`
+- `content-api/responses.ts`
+- `content-api/in-memory-store.ts`
+- `content-api/database-store.ts`
+- `content-api/routes.ts`
+
+This is the safest split because it reduces the file size quickly while keeping
+the rest of the codebase importing the same top-level module path.
+
+## Migration Strategy
+
+1. Extract pure/shared code first:
+   - content types
+   - payload/query types
+   - parsing helpers
+   - response serializers
+2. Extract `createInMemoryContentStore` and keep its private helper functions
+   local to that module.
+3. Extract `createDatabaseContentStore` and keep DB-only helper functions local
+   to that module.
+4. Extract `mountContentApiRoutes` last, after shared helpers and store exports
+   are already stable.
+5. Reduce `content-api.ts` to a thin re-export facade.
+
+## Guardrails
+
+- no public API changes
+- no route changes
+- no behavior changes
+- no test rewrites beyond import-stability needs
+- no opportunistic cleanups mixed into the extraction
+
+## Risks
+
+- accidental type cycles between shared helpers and store modules
+- import path mistakes when moving helpers
+- behavioral drift between in-memory and DB stores if helpers are duplicated
+- route authorization regressions if helper ownership changes
+
+## Mitigation
+
+- keep shared types/helpers in dedicated internal modules
+- keep store-specific helpers private to the relevant store module
+- extract routes last
+- run the existing content API test file after each major extraction step
+
+## Testing
+
+Primary regression gate:
+
+- `bun test apps/server/src/lib/content-api.test.ts`
+
+Full validation after the refactor:
+
+- `bun run format:check`
+- `bun run check`
+
+## Repo Policy Note
+
+This design file is intentionally stored in `docs/plans/` as a local planning
+artifact and should remain untracked per `AGENTS.md`.

+
+**Architecture:** Keep `apps/server/src/lib/content-api.ts` as the only public

+
+**Tech Stack:** Bun, TypeScript, Elysia route handlers, Drizzle ORM,
+postgres.js, node:test, Nx
+
+---
+
+### Task 1: Extract Shared Types and Helper Modules

+- Modify: `apps/server/src/lib/content-api.ts`
+- Test: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Write the failing test**
+
+Use the existing regression suite unchanged as the failing test:
+
+```bash
+bun test apps/server/src/lib/content-api.test.ts
+```
+
+Expected after the extraction starts but before imports are fixed:
+FAIL due to missing exports or moved helper references.
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts`
+Expected: FAIL for import/reference errors caused by the in-progress extraction.
+
+**Step 3: Write minimal implementation**
+
+- move shared types into `types.ts`
+- move input/query parsing helpers into `parsing.ts`
+- move response serializers and row conversion helpers into `responses.ts`
+- update `content-api.ts` to import and re-export the same public API surface
+
+**Step 4: Run test to verify it passes**

+Expected: PASS with no behavior changes.
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/content-api.ts apps/server/src/lib/content-api/types.ts apps/server/src/lib/content-api/parsing.ts apps/server/src/lib/content-api/responses.ts

+- Modify: `apps/server/src/lib/content-api.ts`
+- Test: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Write the failing test**
+
+Use the existing in-memory store coverage in:
+
+- `apps/server/src/lib/content-api.test.ts`
+
+The same test command is the failing test for extraction errors.
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts`
+Expected: FAIL while `createInMemoryContentStore` is partially moved and imports
+are not yet wired correctly.
+
+**Step 3: Write minimal implementation**
+
+- move `createInMemoryContentStore` and its private helper functions into
+  `in-memory-store.ts`
+- keep helper ownership local to the in-memory store module
+- keep `content-api.ts` re-exporting `createInMemoryContentStore`
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts`
+Expected: PASS, including all in-memory route/store behavior.

+# CMS-39 Login Backoff And Failed-Attempt Throttling Design
+
+Date: 2026-03-13
+Status: approved in chat, local planning artifact only
+
+## Goal
+
+Implement deterministic failed-password throttling for MDCMS password-entry flows, with exponential backoff that becomes observable as `429 AUTH_BACKOFF_ACTIVE` responses.
+
+## Source Of Truth
+
+- Roadmap task: `CMS-39` in `ROADMAP_TASKS.md`
+- Owning auth spec: `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
+- Server auth implementation: `apps/server/src/lib/auth.ts`
+- Server auth docs: `apps/server/README.md`
+
+## Approved Spec Delta
+
+Add a concrete throttling contract to `SPEC-005`:
+
+- Failed password login attempts use exponential backoff.
+- The protected password-entry routes are:
+  - `POST /api/v1/auth/login`
+  - `POST /api/v1/auth/cli/login/authorize` when credentials are submitted
+- Backoff state is keyed by normalized email for MVP scope.
+- Invalid credentials without an active backoff return:
+  - status `401`
+  - code `AUTH_INVALID_CREDENTIALS`
+- Requests made while backoff is active return:
+  - status `429`
+  - code `AUTH_BACKOFF_ACTIVE`
+  - header `Retry-After: <seconds>`
+- Backoff resets on successful password sign-in.
+- Backoff also resets after a quiet window of 15 minutes without failed attempts.
+- Exponential schedule for MVP:
+  - attempt 1 sets next delay to `1s`
+  - attempt 2 sets next delay to `2s`
+  - attempt 3 sets next delay to `4s`
+  - attempt 4 sets next delay to `8s`
+  - attempt 5 sets next delay to `16s`
+  - attempt 6+ cap at `32s`
+
+## Server Design
+
+Keep Better Auth responsible for credential verification and session issuance, but own the throttling contract in MDCMS.
+
+### Why Not Better Auth Rate Limiting
+
+- Better Auth has a built-in rate limiter, but MDCMS currently calls `auth.api.signInEmail(...)` server-side in its own wrapper.
+- Better Auth documents that server-side `auth.api` requests are not rate limited.
+- The built-in limiter is request-path based, while `CMS-39` needs failed-attempt-aware exponential backoff with MDCMS-owned status codes and reset rules.
+
+### Persistence Model
+
+Persist throttle state in Postgres so behavior is deterministic across process restarts and test runs.
+
+Proposed table shape:
+
+- `login_key` text primary/unique key
+- `failure_count` integer
+- `first_failed_at` timestamp
+- `last_failed_at` timestamp
+- `next_allowed_at` timestamp
+- `created_at` timestamp
+- `updated_at` timestamp
+
+`login_key` should be the normalized email used for password login attempts.
+
+### Request Flow
+
+For `POST /api/v1/auth/login` and password-backed CLI authorize:
+
+1. Normalize the email.
+2. Read the throttle row for that login key.
+3. If `next_allowed_at > now`, reject immediately with `429 AUTH_BACKOFF_ACTIVE` and `Retry-After`.
+4. If the quiet window has elapsed, treat the row as reset before processing this attempt.
+5. Call Better Auth to verify credentials.
+6. On success:
+   - delete or reset the throttle row
+   - continue with existing session issuance behavior
+7. On invalid credentials:
+   - increment `failure_count`
+   - compute the next delay using the capped exponential schedule
+   - set `last_failed_at` and `next_allowed_at`
+   - return the existing `401 AUTH_INVALID_CREDENTIALS`
+
+This keeps credential failures and active lockout as separate deterministic states.
+
+## Endpoint Coverage
+
+Apply the throttle guard only to password-entry routes owned by `SPEC-005`:
+
+- `POST /api/v1/auth/login`
+- `POST /api/v1/auth/cli/login/authorize` when `email` and `password` are present
+
+Do not apply it to:
+
+- `GET /api/v1/auth/cli/login/authorize`
+- API key flows
+- session reads
+- logout/revoke routes
+- future SSO providers
+
+## Error Handling
+
+- Active backoff returns:
+  - HTTP `429`
+  - code `AUTH_BACKOFF_ACTIVE`
+  - message `Too many failed login attempts. Retry after <seconds> seconds.`
+  - `Retry-After` response header
+- Invalid credentials outside active backoff keep the existing:
+  - HTTP `401`
+  - code `AUTH_INVALID_CREDENTIALS`
+- Internal persistence failures remain `500 INTERNAL_ERROR`
+
+## Testing Strategy
+
+Primary acceptance coverage should prove:
+
+- repeated failed password attempts create exponential backoff state
+- login requests made during backoff return `429` with `Retry-After`
+- successful login clears backoff state
+- quiet-window expiry resets the counter
+- CLI browser authorize shares the same throttling behavior when credentials are posted
+
+Suggested test technique:
+
+- add focused auth tests in `apps/server/src/lib/auth.test.ts`
+- inject or control the clock in auth throttling helpers, or temporarily stub `Date.now()` in tests
+- validate both response semantics and persisted DB state where that gives better signal
+
+## Documentation
+
+- Update `SPEC-005` with the concrete `429` contract.
+- Update `apps/server/README.md` with the new auth abuse behavior and operator-visible response semantics.
+- Add a short code comment near the throttling helper in `auth.ts` explaining why MDCMS owns this logic instead of relying on Better Auth rate limiting.
+
+## Validation
+
+Run from workspace root:
+
+- `bun test apps/server/src/lib/auth.test.ts`
+- `bun test apps/server/src/lib/db/schema.contract.test.ts`
+- `bun run format:check`
+- `bun run check`
+
+## Notes
+
+- `docs/plans/` is intentionally local-only in this repository and should remain untracked.

+# CMS-39 Login Backoff And Failed-Attempt Throttling Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add deterministic password-login throttling with persisted exponential backoff, `429 AUTH_BACKOFF_ACTIVE` responses during active lockout, and reset-on-success behavior for the MDCMS auth flows owned by `SPEC-005`.
+
+**Architecture:** Update `SPEC-005` first, then add a small persisted throttle table in the server schema so backoff state survives process restarts and can be tested deterministically. Route both `POST /api/v1/auth/login` and the credential-submission branch of `POST /api/v1/auth/cli/login/authorize` through a shared auth helper that checks active backoff, records failures, clears state on success, and surfaces `Retry-After` on `429`.
+
+**Tech Stack:** Bun, TypeScript, Elysia, better-auth, Drizzle, Postgres, Bun test
+
+---
+
+### Task 1: Codify The Contract In The Owning Spec
+
+**Files:**
+
+- Modify: `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
+- Modify: `apps/server/README.md`
+
+**Step 1: Update the normative Session Security text**
+
+Add the approved throttling contract under the existing Session Security section:
+
+```md
+- Failed password login attempts apply exponential backoff keyed by normalized email.
+- Active backoff rejects password-entry requests with `AUTH_BACKOFF_ACTIVE` (`429`) and `Retry-After`.
+- Successful password sign-in resets the stored backoff state.
+```
+
+**Step 2: Update the auth endpoint table**
+
+Modify the deterministic error column for:
+
+- `POST /api/v1/auth/login`
+- `POST /api/v1/auth/cli/login/authorize`
+
+so the table includes `AUTH_BACKOFF_ACTIVE` (`429`) in addition to `AUTH_INVALID_CREDENTIALS` (`401)`.
+
+**Step 3: Add the operator-facing server README note**
+
+Document:
+
+- which routes are protected
+- that `Retry-After` is emitted on active backoff
+- that Better Auth rate limiting is not relied on for this contract
+
+**Step 4: Verify the spec delta against CMS-39 acceptance**
+
+Confirm these exact points are present before code changes:
+
+- observable backoff via `429`
+- deterministic error code `AUTH_BACKOFF_ACTIVE`
+- protected flows limited to password-entry routes
+- reset rules: success and quiet-window expiry
+
+**Step 5: Commit the docs checkpoint if using commit gates**
+
+```bash
+git add docs/specs/SPEC-005-auth-authorization-and-request-routing.md apps/server/README.md
+git commit -m "docs: define login backoff contract"
+```
+
+### Task 2: Add Schema Coverage For Persisted Throttle State
+
+**Files:**
+
+- Modify: `apps/server/src/lib/db/schema.ts`
+- Create: `apps/server/drizzle/0008_<name>.sql`
+- Modify: `apps/server/drizzle/meta/_journal.json`
+- Create: `apps/server/drizzle/meta/0008_snapshot.json`
+- Modify: `apps/server/src/lib/db/schema.contract.test.ts`
+
+**Step 1: Add the new Drizzle table definition**
+
+Add a table like:
+
+```ts
+export const authLoginBackoffs = pgTable(
+  "auth_login_backoffs",
+  {
+    id: uuid().defaultRandom().primaryKey(),
+    loginKey: text().notNull(),
+    failureCount: integer().notNull().default(0),
+    firstFailedAt: timestamp({ withTimezone: true }).notNull(),
+    lastFailedAt: timestamp({ withTimezone: true }).notNull(),
+    nextAllowedAt: timestamp({ withTimezone: true }).notNull(),
+    createdAt: timestamp({ withTimezone: true }).defaultNow().notNull(),
+    updatedAt: timestamp({ withTimezone: true }).defaultNow().notNull(),
+  },
+  (table) => [
+    unique("uniq_auth_login_backoffs_login_key").on(table.loginKey),
+    index("idx_auth_login_backoffs_next_allowed").on(table.nextAllowedAt),
+  ],
+);
+```
+
+If the team prefers no surrogate `id`, use `loginKey` as the primary key instead, but keep the final schema and migration aligned.
+
+**Step 2: Write the SQL migration and snapshot**
+
+Create the migration that adds `auth_login_backoffs` plus the required named index/constraint, then update the journal and latest snapshot under `apps/server/drizzle/meta/`.
+
+**Step 3: Extend the schema contract test**
+
+Add `public.auth_login_backoffs` to the expected tables and assert the named unique/index entries:
+
+```ts
+"public.auth_login_backoffs": [
+  "id",
+  "login_key",
+  "failure_count",
+  "first_failed_at",
+  "last_failed_at",
+  "next_allowed_at",
+  "created_at",
+  "updated_at",
+]
+```
+
+**Step 4: Run the schema contract test**
+
+Run: `bun test apps/server/src/lib/db/schema.contract.test.ts`
+
+Expected: FAIL until the new table, migration artifacts, and snapshot assertions all match.
+
+**Step 5: Commit the schema checkpoint**
+
+```bash
+git add apps/server/src/lib/db/schema.ts apps/server/drizzle apps/server/src/lib/db/schema.contract.test.ts
+git commit -m "feat(server): add persisted login backoff table"
+```
+
+### Task 3: Add Red Auth Tests For Backoff Semantics
+
+**Files:**
+
+- Modify: `apps/server/src/lib/auth.test.ts`
+
+**Step 1: Add clock-control helpers for auth throttling tests**
+
+Prefer a narrow helper local to this test file:
+
+```ts
+async function withMockedNow<T>(
+  value: number,
+  run: () => Promise<T>,
+): Promise<T> {
+  const originalNow = Date.now;
+  Date.now = () => value;
+  try {
+    return await run();
+  } finally {
+    Date.now = originalNow;
+  }
+}
+```
+
+If `auth.ts` already accepts a clock dependency by the time you implement this, use that instead of monkey-patching.
+
+**Step 2: Add failing tests for direct login**
+
+Add tests that prove:
+
+- first invalid password attempt returns `401 AUTH_INVALID_CREDENTIALS`
+- immediate retry returns `429 AUTH_BACKOFF_ACTIVE`
+- `Retry-After` reflects the stored delay
+- advancing beyond the delay allows another credential check
+- successful login clears the backoff row
+
+Example assertion shape:
+
+```ts
+assert.equal(response.status, 429);
+assert.equal(body.error.code, "AUTH_BACKOFF_ACTIVE");
+assert.equal(response.headers.get("retry-after"), "1");
+```
+
+**Step 3: Add failing tests for CLI authorize**
+
+Cover the credential-submission branch of `POST /api/v1/auth/cli/login/authorize`:
+
+- invalid credentials return `401`
+- immediate retry while locked returns `429`
+- active lockout does not mutate the challenge into an authorized state
+
+**Step 4: Run the focused auth suite**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+
+Expected: FAIL on the new throttling assertions because no backoff state exists yet.
+
+**Step 5: Commit the red-test checkpoint**
+
+```bash
+git add apps/server/src/lib/auth.test.ts
+git commit -m "test(server): add CMS-39 login backoff coverage"
+```
+
+### Task 4: Implement Shared Login Backoff Helpers
+
+**Files:**
+
+- Modify: `apps/server/src/lib/auth.ts`
+
+**Step 1: Add constants and helper functions near the auth constants**
+
+Add small, explicit constants:
+
+```ts
+const LOGIN_BACKOFF_RESET_WINDOW_MS = 15 * 60 * 1000;
+const LOGIN_BACKOFF_DELAYS_SECONDS = [1, 2, 4, 8, 16, 32] as const;
+```
+
+Add helpers for:
+
+- normalizing email to a throttle key
+- reading the current backoff row
+- deciding whether the row has expired into a fresh window
+- computing the next delay
+- computing `Retry-After`
+- upserting failure state
+- clearing state on success
+
+**Step 2: Add a deterministic runtime error for active backoff**
+
+Throw a `RuntimeError` like:
+
+```ts
+throw new RuntimeError({
+  code: "AUTH_BACKOFF_ACTIVE",
+  message: `Too many failed login attempts. Retry after ${retryAfterSeconds} seconds.`,
+  statusCode: 429,
+});
+```
+
+Keep the header emission path separate so the response also includes:
+
+```ts
+{ "retry-after": String(retryAfterSeconds) }
+```
+
+**Step 3: Route password login through the helper flow**
+
+Refactor `loginWithEmailPassword(...)` so it:
+
+1. normalizes the email
+2. checks for active backoff before calling Better Auth
+3. calls `auth.api.signInEmail(...)`
+4. on invalid credentials, records the next backoff state and rethrows `AUTH_INVALID_CREDENTIALS`
+5. on success, clears the backoff row before returning the session data
+
+Avoid changing unrelated session, CSRF, API key, or SSO behavior.
+
+**Step 4: Re-run the focused auth suite**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+
+Expected: the direct-login throttling tests now pass; any remaining failures should be limited to route-response header plumbing or CLI-path integration.
+
+**Step 5: Commit the helper implementation**
+
+```bash
+git add apps/server/src/lib/auth.ts
+git commit -m "feat(server): add shared login backoff helpers"
+```
+
+### Task 5: Surface `429` Headers On Both Password Routes
+
+**Files:**
+
+- Modify: `apps/server/src/lib/auth.ts`
+
+**Step 1: Extend the auth service result shape if needed**
+
+If `loginWithEmailPassword(...)` needs to return metadata for callers, keep it minimal:
+
+```ts
+type LoginResult = {
+  session: StudioSession;
+  setCookie: string;
+};
+```
+
+For throttled requests, prefer central runtime-error handling with support for extra response headers rather than returning unions from every auth path.
+
+**Step 2: Ensure `executeWithRuntimeErrorsHandled(...)` can emit `Retry-After`**
+
+If the runtime error handler already supports extra headers, reuse that. If not, extend the smallest shared error path so a `RuntimeError` can carry response headers without changing unrelated API behavior.
+
+**Step 3: Verify both routes now share the same throttle behavior**
+
+Confirm:
+
+- `POST /api/v1/auth/login`
+- password-backed `POST /api/v1/auth/cli/login/authorize`
+
+both return `429 AUTH_BACKOFF_ACTIVE` with `Retry-After` when blocked.
+
+**Step 4: Run auth tests again**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+
+Expected: PASS
+
+**Step 5: Commit the response-plumbing checkpoint**
+
+```bash
+git add apps/server/src/lib/auth.ts
+git commit -m "feat(server): return retry-after for throttled logins"
+```
+
+### Task 6: Finish Docs, Formatting, And Validation
+
+**Files:**
+
+- Modify: `apps/server/README.md`
+- Modify: `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
+- Modify: `apps/server/src/lib/auth.ts`
+- Modify: `apps/server/src/lib/auth.test.ts`
+- Modify: `apps/server/src/lib/db/schema.ts`
+- Modify: `apps/server/src/lib/db/schema.contract.test.ts`
+- Modify: `apps/server/drizzle/...`
+
+**Step 1: Add the point-of-use code comment**
+
+Place one short comment near the throttling helper in `auth.ts` explaining:
+
+```ts
+// MDCMS owns failed-attempt backoff here because server-side auth.api calls are outside Better Auth's built-in rate limiter.
+```
+
+**Step 2: Run the focused verification commands**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/auth.test.ts
+bun test apps/server/src/lib/db/schema.contract.test.ts
+```
+
+Expected: PASS
+
+**Step 3: Run workspace-level verification**
+
+Run:
+
+```bash
+bun run format:check
+bun run check
+```
+
+Expected: PASS
+
+If `bun run check` is too broad for local-only blockers unrelated to this task, capture the exact failure and stop before claiming success.
+
+**Step 4: Inspect git status for task scope hygiene**
+
+Run:
+
+```bash
+git status --short
+```
+
+Confirm:
+
+- only `CMS-39`-relevant tracked files are modified
+- local-only paths such as `docs/plans/`, `AGENTS.md`, `ROADMAP_TASKS.md`, `.claude/`, and `.codex/` are not staged
+
+**Step 5: Commit the final task-scoped implementation**
+
+```bash
+git add docs/specs/SPEC-005-auth-authorization-and-request-routing.md apps/server/README.md apps/server/src/lib/auth.ts apps/server/src/lib/auth.test.ts apps/server/src/lib/db/schema.ts apps/server/src/lib/db/schema.contract.test.ts apps/server/drizzle

+# CMS-33 Design
+
+Date: 2026-03-14
+Task: CMS-33 - Implement server module bootstrap + manifest/dependency/collision validation
+
+## Context
+
+Roadmap source:
+
+- `ROADMAP_TASKS.md` CMS-33
+
+Owning spec:
+
+- `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
+
+Relevant upstream tasks:
+
+- CMS-9 shared extensibility contracts
+- CMS-10 unified module topology
+- CMS-13 scoped content DAL helpers
+
+Relevant downstream tasks:
+
+- CMS-34 action registry + action catalog + Studio bootstrap endpoints
+- CMS-35 extensibility contract validation suite
+
+## Spec Delta Summary
+
+No new spec file changes were present in the workspace. CMS-33 is already specified by the owning spec and roadmap.
+
+The clarified contract for this task is:
+
+- server startup validates a full module dependency graph
+- missing `dependsOn` targets fail startup before route registration
+- dependency cycles fail startup
+- startup emits one deterministic aggregated validation report instead of stopping at the first violation
+- explicit composition-root dependency wiring remains required; no DI container or service locator runtime patterns are introduced
+
+## Chosen Approach
+
+Chosen approach: replace the permissive shared module loader path with a strict shared bootstrap pipeline used by both server and CLI internals, while anchoring the user-visible acceptance behavior to server startup.
+
+Why this approach:
+
+- it is the cleanest long-term architecture
+- it prevents server and CLI from diverging on dependency ordering and validation semantics
+- it keeps the hard logic in `@mdcms/shared`, which CMS-34 and CMS-35 can reuse directly
+
+## Architecture
+
+The current shared loader/report path is permissive: invalid or incompatible modules become "skipped" entries. CMS-33 requires fail-fast startup validation, so the shared runtime layer becomes the source of truth for strict bootstrap planning.
+
+The shared bootstrap pipeline will:
+
+1. Validate module package shape and manifest compatibility.
+2. Index modules by `manifest.id`.
+3. Detect duplicate module IDs.
+4. Validate dependency existence for `dependsOn`.
+5. Detect dependency cycles.
+6. Compute deterministic topological order, using `manifest.id` as the stable tie-breaker.
+7. Project the ordered module graph into runtime-specific plans.
+8. Validate runtime-surface collisions, including duplicate server `action.id`.
+9. Return either a deterministic ordered plan or a deterministic aggregated bootstrap failure.
+
+Server and CLI loaders become thin wrappers over the shared strict planner.
+
+Server-specific behavior for CMS-33:
+
+- startup throws before action collection
+- startup throws before module route registration
+- mounted modules continue to receive explicitly assembled dependencies from the composition root
+
+CLI behavior in this task:
+
+- consume the same strict planner for ordering and internal consistency
+- avoid changing CLI operator-facing semantics unless the refactor makes a small documentation update necessary
+
+## Failure Model
+
+Bootstrap violations are collected into one deterministic failure payload with:
+
+- one stable top-level runtime error code
+- a stable, sorted list of violation entries
+- machine-usable `details` for unit and integration tests
+
+Violation kinds expected in scope:
+
+- `INVALID_PACKAGE`
+- `INCOMPATIBLE_MANIFEST`
+- `DUPLICATE_MODULE_ID`
+- `MISSING_DEPENDENCY`
+- `DEPENDENCY_CYCLE`
+- `DUPLICATE_ACTION_ID`
+
+Missing runtime surface is not treated as a bootstrap failure by itself. It only means that a module does not participate in that runtime.
+
+## Files In Scope
+
+Shared runtime core:
+
+- `packages/shared/src/lib/runtime/module-loader-core.ts`
+- `packages/shared/src/lib/runtime/module-loader-core.test.ts`
+- `packages/shared/src/lib/runtime/index.ts`
+- `packages/shared/README.md`
+
+Server integration:
+
+- `apps/server/src/lib/module-loader.ts`
+- `apps/server/src/lib/module-loader.test.ts`
+- `apps/server/src/lib/runtime-with-modules.ts`
+- `apps/server/src/lib/runtime-with-modules.test.ts`
+- `apps/server/README.md`
+
+CLI internal alignment:
+
+- `apps/cli/src/lib/module-loader.ts`
+- `apps/cli/src/lib/module-loader.test.ts`
+- `apps/cli/src/lib/runtime-with-modules.ts`
+
+## Test Strategy
+
+Shared unit coverage:
+
+- duplicate module IDs
+- missing dependencies
+- dependency cycle detection
+- deterministic topological ordering
+- duplicate server action IDs
+- deterministic aggregation and sorting of bootstrap errors
+
+Server integration coverage:
+
+- invalid graph fails before route registration
+- duplicate action IDs fail before action collection
+- explicit dependency wiring is still passed through `mount(app, deps)`
+
+CLI regression coverage:
+
+- deterministic ordering still holds through the new shared bootstrap pipeline
+- runtime-specific extraction still returns expected aliases/formatters/hooks
+
+## Documentation
+
+Document at point of use:
+
+- shared README describes the strict bootstrap planner and deterministic failure semantics
+- server README states that module bootstrap now fails startup on manifest, dependency, cycle, and action ID collisions
+
+## Constraints
+
+- `docs/plans/` is local-only in this repository and must remain untracked
+- user explicitly requested staying in the main workdir instead of creating a worktree

+# CMS-33 Strict Module Bootstrap Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Replace permissive module loading with a strict shared bootstrap pipeline and make server startup fail fast on manifest, dependency, cycle, compatibility, and action ID violations before any module routes are registered.
+
+**Architecture:** Build a runtime-agnostic bootstrap planner in `@mdcms/shared` that validates module packages, computes deterministic dependency ordering, and returns either an ordered runtime plan or an aggregated bootstrap failure. Refactor server and CLI loaders to consume that planner; activate fail-fast startup semantics in the server while preserving explicit composition-root dependency wiring.
+
+**Tech Stack:** Bun, Nx, TypeScript, node:test, Zod, Elysia
+
+---
+
+### Task 1: Replace permissive shared load reports with a strict bootstrap planner
+
+**Files:**
+
+- Modify: `packages/shared/src/lib/runtime/module-loader-core.ts`
+- Modify: `packages/shared/src/lib/runtime/module-loader-core.test.ts`
+- Modify: `packages/shared/src/lib/runtime/index.ts`
+- Test: `packages/shared/src/lib/runtime/module-loader-core.test.ts`
+
+**Step 1: Write the failing shared bootstrap tests**
+
+Add tests to `packages/shared/src/lib/runtime/module-loader-core.test.ts` for:
+
+- duplicate `manifest.id`
+- missing `dependsOn`
+- dependency cycle detection
+- deterministic topological ordering with `manifest.id` tie-breaking
+- duplicate server `action.id`
+- deterministic aggregated violation ordering
+
+Use helpers like:
+
+```ts
+const alpha = createModule("alpha", {
+  server: true,
+  dependsOn: ["core.system"],
+});
+
+const beta = createModule("beta", {
+  server: true,
+  dependsOn: ["alpha"],
+});
+
+const plan = buildRuntimeModulePlan([beta, alpha, coreSystem], {
+  coreVersion: "1.0.0",
+  runtime: "server",
+  surface: "server",
+  logger: createNoopLogger(),
+});
+
+assert.equal(plan.ok, true);
+assert.deepEqual(plan.moduleIds, ["core.system", "alpha", "beta"]);
+```
+
+And failing cases like:
+
+```ts
+const plan = buildRuntimeModulePlan([a, b], {
+  coreVersion: "1.0.0",
+  runtime: "server",
+  surface: "server",
+  logger: createNoopLogger(),
+});
+
+assert.equal(plan.ok, false);
+assert.deepEqual(
+  plan.violations.map((entry) => entry.code),
+  ["DUPLICATE_MODULE_ID"],
+);
+```
+
+**Step 2: Run the shared test file to verify it fails**
+
+Run:
+
+```bash
+bun test packages/shared/src/lib/runtime/module-loader-core.test.ts
+```
+
+Expected: FAIL because `buildRuntimeModulePlan(...)` and strict bootstrap semantics do not exist yet.
+
+**Step 3: Implement the strict shared planner**
+
+In `packages/shared/src/lib/runtime/module-loader-core.ts`, replace the skip-oriented model with planner-first types and logic such as:
+
+```ts
+export type ModuleBootstrapViolationCode =
+  | "INVALID_PACKAGE"
+  | "INCOMPATIBLE_MANIFEST"
+  | "DUPLICATE_MODULE_ID"
+  | "MISSING_DEPENDENCY"
+  | "DEPENDENCY_CYCLE"
+  | "DUPLICATE_ACTION_ID";
+
+export type ModuleBootstrapViolation = {
+  code: ModuleBootstrapViolationCode;
+  moduleId: string;
+  details: string;
+};
+
+export type RuntimeModulePlan<TSurface extends ModuleSurface> =
+  | {
+      ok: true;
+      moduleIds: readonly string[];
+      loaded: readonly LoadedModule<TSurface>[];
+    }
+  | {
+      ok: false;
+      violations: readonly ModuleBootstrapViolation[];
+    };
+```
+
+Implementation rules:
+
+- validate package shape and manifest compatibility first
+- collect duplicate module IDs before graph traversal
+- validate every `dependsOn` target exists
+- detect cycles with DFS or Kahn-based cycle detection
+- compute deterministic topological ordering using `manifest.id` as tie-breaker
+- filter to modules exposing the requested runtime surface
+- validate duplicate server `action.id` after ordering
+- sort violations deterministically by code, then module ID, then details
+
+Export the planner from `packages/shared/src/lib/runtime/index.ts`.
+
+**Step 4: Re-run the shared test file**
+
+Run:
+
+```bash
+bun test packages/shared/src/lib/runtime/module-loader-core.test.ts
+```
+
+Expected: PASS.
+
+**Step 5: Commit the shared bootstrap planner**
+
+```bash
+git add packages/shared/src/lib/runtime/module-loader-core.ts packages/shared/src/lib/runtime/module-loader-core.test.ts packages/shared/src/lib/runtime/index.ts
+git commit -m "refactor(shared): add strict module bootstrap planner"
+```
+
+### Task 2: Refactor server loaders to fail fast before route registration
+
+**Files:**
+
+- Modify: `apps/server/src/lib/module-loader.ts`
+- Modify: `apps/server/src/lib/module-loader.test.ts`
+- Modify: `apps/server/src/lib/runtime-with-modules.ts`
+- Modify: `apps/server/src/lib/runtime-with-modules.test.ts`
+- Test: `apps/server/src/lib/module-loader.test.ts`
+- Test: `apps/server/src/lib/runtime-with-modules.test.ts`
+
+**Step 1: Write failing server tests**
+
+Update server tests to assert:
+
+- duplicate action IDs cause startup failure
+- missing dependency targets cause startup failure
+- failures happen before `mountLoadedServerModules(...)`
+- explicit deps are still passed into `mount(app, deps)`
+
+Add a mount-guard test like:
+
+```ts
+let mounted = false;
+
+const invalid = createServerModule("broken", {
+  dependsOn: ["missing.core"],
+  onMount: () => {
+    mounted = true;
+  },
+});
+
+assert.throws(
+  () =>
+    createServerRequestHandlerWithModules({
+      env,
+      logger,
+      moduleLoadReport: buildServerModuleLoadReport([invalid], {
+        coreVersion: "1.0.0",
+        logger,
+      }),
+    }),
+  /MISSING_DEPENDENCY/,
+);
+
+assert.equal(mounted, false);
+```
+
+**Step 2: Run the server loader tests to verify they fail**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/module-loader.test.ts apps/server/src/lib/runtime-with-modules.test.ts
+```
+
+Expected: FAIL because server code still treats invalid or incompatible modules as skip/report data instead of throwing before startup proceeds.
+
+**Step 3: Implement strict server bootstrap consumption**
+
+In `apps/server/src/lib/module-loader.ts`:
+
+- replace `buildServerModuleLoadReport(...)` internals to call the shared strict planner
+- return a validated ordered plan for server modules
+- throw one `RuntimeError` for bootstrap failures with a stable top-level code such as `INVALID_MODULE_BOOTSTRAP`
+
+In `apps/server/src/lib/runtime-with-modules.ts`:
+
+- build the server module plan before collecting actions
+- build the plan before mounting routes
+- keep `moduleDeps` explicit and continue passing them directly into each module `mount`
+
+Shape the failure like:
+
+```ts
+throw new RuntimeError({
+  code: "INVALID_MODULE_BOOTSTRAP",
+  message: "Server module bootstrap failed.",
+  statusCode: 500,
+  details: {
+    violations,
+  },
+});
+```
+
+**Step 4: Re-run the server loader tests**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/module-loader.test.ts apps/server/src/lib/runtime-with-modules.test.ts
+```
+
+Expected: PASS.
+
+**Step 5: Commit the server fail-fast refactor**
+
+```bash
+git add apps/server/src/lib/module-loader.ts apps/server/src/lib/module-loader.test.ts apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/runtime-with-modules.test.ts
+git commit -m "feat(server): fail fast on invalid module bootstrap"
+```
+
+### Task 3: Move CLI loaders onto the same strict ordered planner
+
+**Files:**
+
+- Modify: `apps/cli/src/lib/module-loader.ts`
+- Modify: `apps/cli/src/lib/module-loader.test.ts`
+- Modify: `apps/cli/src/lib/runtime-with-modules.ts`
+- Test: `apps/cli/src/lib/module-loader.test.ts`
+
+**Step 1: Write failing CLI tests around the new shared semantics**
+
+Adjust CLI tests so they assert:
+
+- deterministic ordered module IDs still hold under the strict planner
+- aliases, output formatters, and preflight hooks are collected from ordered loaded CLI modules
+- invalid-package or missing-dependency planner failures surface predictably if the CLI wrapper receives an invalid candidate set
+
+**Step 2: Run the CLI loader test to verify it fails**
+
+Run:
+
+```bash
+bun test apps/cli/src/lib/module-loader.test.ts
+```
+
+Expected: FAIL because the CLI loader still depends on the old skip-report shape.
+
+**Step 3: Refactor CLI loaders to consume the shared planner**
+
+In `apps/cli/src/lib/module-loader.ts` and `apps/cli/src/lib/runtime-with-modules.ts`:
+
+- swap old report-builder usage for the strict shared planner
+- keep the runtime-specific extraction for aliases, output formatters, and preflight hooks
+- preserve existing CLI runtime shape as much as possible so CMS-33 does not become a CLI behavior task
+
+**Step 4: Re-run the CLI loader test**
+
+Run:
+
+```bash
+bun test apps/cli/src/lib/module-loader.test.ts
+```
+
+Expected: PASS.
+
+**Step 5: Commit the CLI planner alignment**
+
+```bash
+git add apps/cli/src/lib/module-loader.ts apps/cli/src/lib/module-loader.test.ts apps/cli/src/lib/runtime-with-modules.ts
+git commit -m "refactor(cli): align module bootstrap with shared planner"
+```
+
+### Task 4: Update documentation and verify the full task scope
+
+**Files:**
+
+- Modify: `packages/shared/README.md`
+- Modify: `apps/server/README.md`
+- Test: `packages/shared/src/lib/runtime/module-loader-core.test.ts`
+- Test: `apps/server/src/lib/module-loader.test.ts`
+- Test: `apps/server/src/lib/runtime-with-modules.test.ts`
+- Test: `apps/cli/src/lib/module-loader.test.ts`
+
+**Step 1: Update point-of-use docs**
+
+Document:
+
+- the strict bootstrap planner and deterministic violation model in `packages/shared/README.md`
+- server startup fail-fast semantics in `apps/server/README.md`
+
+Keep CLI README changes minimal unless a user-facing behavior description actually changes.
+
+**Step 2: Run focused tests**
+
+Run:
+
+```bash
+bun test packages/shared/src/lib/runtime/module-loader-core.test.ts
+bun test apps/server/src/lib/module-loader.test.ts apps/server/src/lib/runtime-with-modules.test.ts
+bun test apps/cli/src/lib/module-loader.test.ts
+```
+
+Expected: PASS.
+
+**Step 3: Run required repo checks**
+
+Run:
+
+```bash
+bun run format:check
+bun run check
+```
+
+Expected: PASS.
+
+**Step 4: Review git status for task scope hygiene**
+
+Run:
+
+```bash
+git status --short
+```
+
+Expected:
+
+- only CMS-33 code/docs changes are staged
+- local-only paths remain unstaged and uncommitted, including `docs/plans/`
+
+**Step 5: Commit the docs and verification pass**
+
+```bash
+git add packages/shared/README.md apps/server/README.md
+git commit -m "docs: record strict module bootstrap behavior"
+```

+# CMS-34 Action Catalog and Studio Bootstrap Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Publish the canonical module action catalog and the MVP `module`-mode Studio bootstrap/runtime asset endpoints from the server without pulling loader execution work forward from CMS-60.
+
+**Architecture:** Extend the existing server request-handler composition so it publishes two canonical backend contracts from startup-prepared data: a deterministic filtered action registry and a cached Studio runtime publication snapshot. Keep shared contract validation in `@mdcms/shared`, artifact generation in `@mdcms/studio`, and HTTP publication/error handling in `@mdcms/server`.
+
+**Tech Stack:** Bun, Nx, TypeScript, node:test, Elysia, Zod, filesystem APIs
+
+---
+
+### Task 1: Add a server-owned Studio runtime publication helper
+
+**Files:**
+
+- Create: `apps/server/src/lib/studio-bootstrap.ts`
+- Create: `apps/server/src/lib/studio-bootstrap.test.ts`
+- Modify: `apps/server/src/index.ts`
+- Modify: `apps/server/package.json`
+- Test: `apps/server/src/lib/studio-bootstrap.test.ts`
+
+**Step 1: Write the failing publication-helper tests**
+
+Add tests to `apps/server/src/lib/studio-bootstrap.test.ts` for:
+
+- building one validated `StudioBootstrapManifest`
+- returning `mode: "module"` in the manifest
+- resolving the active `buildId` and asset root
+- returning asset metadata for an existing runtime file
+- returning `undefined` for an unknown `buildId` or missing asset path
+
+Use a temp directory and a tiny fixture source file so the helper can call the real Studio artifact builder. Model the assertions like:
+
+```ts
+const publication = await createStudioRuntimePublication({
+  sourceFile,
+  outDir,
+  studioVersion: "1.2.3",
+});
+
+assert.equal(publication.manifest.mode, "module");
+assert.equal(publication.manifest.buildId, publication.buildId);
+
+const asset = await publication.getAsset({
+  buildId: publication.buildId,
+  assetPath: publication.entryFile,
+});
+
+assert.equal(asset?.contentType, "text/javascript; charset=utf-8");
+assert.equal(asset?.absolutePath.endsWith(publication.entryFile), true);
+```
+
+**Step 2: Run the new publication-helper test file**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/studio-bootstrap.test.ts
+```
+
+Expected: FAIL because the helper does not exist yet.
+
+**Step 3: Implement the publication helper**
+
+Create `apps/server/src/lib/studio-bootstrap.ts` with a small server-owned abstraction around `buildStudioRuntimeArtifacts(...)`, for example:
+
+```ts
+export type StudioRuntimePublication = {
+  buildId: string;
+  entryFile: string;
+  manifest: StudioBootstrapManifest;
+  getAsset: (input: {
+    buildId: string;
+    assetPath: string;
+  }) => Promise<StudioRuntimeAsset | undefined>;
+};
+```
+
+Implementation rules:
+
+- call `buildStudioRuntimeArtifacts(...)` once
+- force `mode: "module"` unless a future spec changes this task contract
+- validate `manifest` with shared validators before returning
+- normalize asset paths so callers cannot escape the active build root
+- return `undefined` instead of throwing for unknown build IDs or missing files
+
+Also:
+
+- export the helper from `apps/server/src/index.ts`
+- add `@mdcms/studio` as a workspace dependency in `apps/server/package.json`
+
+**Step 4: Re-run the publication-helper test file**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/studio-bootstrap.test.ts
+```
+
+Expected: PASS.
+
+**Step 5: Commit the publication helper**
+
+```bash
+git add apps/server/src/lib/studio-bootstrap.ts apps/server/src/lib/studio-bootstrap.test.ts apps/server/src/index.ts apps/server/package.json
+git commit -m "feat(server): add studio runtime publication helper"
+```
+
+### Task 2: Expose `/api/v1/studio/bootstrap` and `/api/v1/studio/assets/:buildId/*` from the shared server handler
+
+**Files:**
+
+- Modify: `apps/server/src/lib/server.ts`
+- Modify: `apps/server/src/lib/http-utils.ts`
+- Modify: `apps/server/src/lib/health.test.ts`
+- Test: `apps/server/src/lib/health.test.ts`
+
+**Step 1: Write the failing server contract tests**
+
+Extend `apps/server/src/lib/health.test.ts` with tests for:
+
+- `GET /api/v1/studio/bootstrap` returns `200` with the prepared manifest
+- `GET /api/v1/studio/assets/:buildId/*` returns the expected JavaScript bytes and content type
+- unknown `buildId` returns a `404 NOT_FOUND` envelope
+- missing asset under a known build returns a `404 NOT_FOUND` envelope
+
+Use a stubbed publication object so the tests stay fast and isolated:
+
+```ts
+const handler = createServerRequestHandler({
+  env: baseEnv,
+  studioRuntimePublication: {
+    manifest,
+    buildId: "abc123",
+    entryFile: "studio-runtime.abc123.mjs",
+    getAsset: async ({ buildId, assetPath }) =>
+      buildId === "abc123" && assetPath === "studio-runtime.abc123.mjs"
+        ? {
+            body: "export const marker = 'runtime';\n",
+            contentType: "text/javascript; charset=utf-8",
+          }
+        : undefined,
+  },
+});
+```
+
+**Step 2: Run the shared server contract tests**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/health.test.ts
+```
+
+Expected: FAIL because `createServerRequestHandler(...)` does not support Studio runtime publication routes yet.
+
+**Step 3: Implement Studio publication routes in the server handler**
+
+Modify `apps/server/src/lib/server.ts` to accept a new option such as:
+
+```ts
+studioRuntimePublication?: StudioRuntimePublication;
+```
+
+Then:
+
+- mount `GET /api/v1/studio/bootstrap`
+- mount `GET /api/v1/studio/assets/:buildId/*`
+- return plain asset responses for successful asset requests
+- convert missing publication or missing files into the standard `NOT_FOUND` server envelope
+
+Use helper functions in `apps/server/src/lib/http-utils.ts` to create non-JSON responses cleanly, for example:
+
+```ts
+export function createTextResponse(
+  body: string,
+  statusCode: number,
+  contentType: string,
+): Response;
+```
+
+Implementation rules:
+
+- keep `/api/v1` as the only supported base path
+- keep action catalog behavior unchanged
+- keep bootstrap and asset routes public per spec
+- keep error normalization inside the existing handler flow
+
+**Step 4: Re-run the server contract tests**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/health.test.ts
+```
+
+Expected: PASS.
+
+**Step 5: Commit the server route publication work**
+
+```bash
+git add apps/server/src/lib/server.ts apps/server/src/lib/http-utils.ts apps/server/src/lib/health.test.ts
+git commit -m "feat(server): publish studio bootstrap endpoints"
+```
+
+### Task 3: Wire module runtime composition to publish actions and Studio runtime together
+
+**Files:**
+
+- Modify: `apps/server/src/lib/runtime-with-modules.ts`
+- Modify: `apps/server/src/lib/runtime-with-modules.test.ts`
+- Test: `apps/server/src/lib/runtime-with-modules.test.ts`
+
+**Step 1: Write the failing integration tests**
+
+Extend `apps/server/src/lib/runtime-with-modules.test.ts` so it verifies:
+
+- bundled module actions still appear at `GET /api/v1/actions`
+- bundled module probe routes still return `200`
+- `GET /api/v1/studio/bootstrap` returns a validated manifest from the composed runtime
+- `GET /api/v1/studio/assets/:buildId/<entryFile>` returns `200`
+
+Inject a temp output directory into the runtime setup so the test does not depend on repo-global artifact paths.
+
+**Step 2: Run the runtime integration tests**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/runtime-with-modules.test.ts
+```
+
+Expected: FAIL because the composed runtime does not prepare or pass a Studio publication snapshot yet.
+
+**Step 3: Implement startup publication wiring**
+
+Modify `apps/server/src/lib/runtime-with-modules.ts` to:
+
+- build the Studio runtime publication snapshot during server startup
+- pass that snapshot into `createServerRequestHandler(...)`
+- keep module action collection and route mounting behavior intact
+
+Recommended shape:
+
+```ts
+const studioRuntimePublication =
+  awaitOrBuildStudioRuntimePublication(...);
+
+const handler = createServerRequestHandler({
+  ...,
+  actions,
+  studioRuntimePublication,
+  configureApp: (app) => {
+    mountLoadedServerModules(app, moduleDeps, moduleLoadReport);
+  },
+});
+```
+
+If the current constructor shape is synchronous, refactor only as much as needed to prepare the publication snapshot without widening scope beyond this task. Prefer explicit inputs such as optional `studioRuntimePublication` or `studioRuntimeOptions` over hidden global state.
+
+**Step 4: Re-run the runtime integration tests**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/runtime-with-modules.test.ts
+```
+
+Expected: PASS.
+
+**Step 5: Commit the runtime composition wiring**
+
+```bash
+git add apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/runtime-with-modules.test.ts
+git commit -m "feat(server): compose module actions with studio publication"
+```
+
+### Task 4: Document the new contracts and run workspace verification
+
+**Files:**
+
+- Modify: `apps/server/README.md`
+- Modify: `packages/studio/README.md`
+
+**Step 1: Update point-of-use documentation**
+
+Document in `apps/server/README.md`:
+
+- `GET /api/v1/studio/bootstrap`
+- `GET /api/v1/studio/assets/:buildId/*`
+- immutable `buildId` asset semantics
+- MVP bootstrap mode fixed to `module`
+
+Document in `packages/studio/README.md`:
+
+- runtime artifacts are built in `@mdcms/studio`
+- publication now happens from `@mdcms/server`
+- loader execution/verification remains deferred to CMS-60
+
+**Step 2: Run focused tests**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/studio-bootstrap.test.ts apps/server/src/lib/health.test.ts apps/server/src/lib/runtime-with-modules.test.ts
+```
+
+Expected: PASS.
+
+**Step 3: Run format and workspace checks**
+
+Run:
+
+```bash
+bun run format:check
+bun run check
+```
+
+Expected: PASS.
+
+**Step 4: Review git status**
+
+Run:
+
+```bash
+git status --short
+```
+

+# CMS-34 Design
+
+Date: 2026-03-14
+Task: CMS-34 - Implement action registry + action catalog + Studio bootstrap endpoints
+
+## Context
+
+Roadmap source:
+
+- `ROADMAP_TASKS.md` CMS-34
+
+Owning specs:
+
+- `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
+- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+- `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
+
+Relevant upstream tasks:
+
+- CMS-5 typed action catalog contract baseline
+- CMS-9 shared extensibility contracts
+- CMS-10 Studio runtime artifact topology
+- CMS-21 content API baseline
+- CMS-33 strict server module bootstrap
+
+Relevant downstream tasks:
+
+- CMS-35 contract validation suite for extensibility
+- CMS-60 `@mdcms/studio` runtime loader + composition surfaces
+
+## Spec Delta Summary
+
+No spec file edits were present in the workspace for this task. During planning, the unresolved Studio execution-mode decision in the owning specs was clarified for MVP execution:
+
+- `/api/v1/studio/bootstrap` must always publish `mode: "module"` in MVP
+- `iframe` mode remains deferred to later spec/task work
+
+That clarification affects the normative Studio bootstrap contract used by `CMS-34` acceptance criteria 1 and 5.
+
+## Chosen Approach
+
+Chosen approach: keep shared contracts as the source of truth, add server-side publication of canonical action and Studio runtime metadata, and avoid introducing loader-side runtime execution work that belongs to CMS-60.
+
+Why this approach:
+
+- it stays inside `CMS-34` scope
+- it builds directly on the existing strict module bootstrap and Studio artifact builder
+- it gives downstream Studio loader work a stable backend contract without inventing extra surfaces
+
+## Architecture
+
+`CMS-34` is primarily a server publication task.
+
+The server already has:
+
+- strict module bootstrap in `apps/server/src/lib/module-loader.ts`
+- action catalog route contract source in `apps/server/src/lib/action-catalog-contract.ts`
+- runtime composition in `apps/server/src/lib/runtime-with-modules.ts`
+- Studio artifact generation in `packages/studio/src/lib/build-runtime.ts`
+
+This task adds a server-owned publication layer with two responsibilities:
+
+1. Derive one deterministic in-memory action registry from mounted server module surfaces.
+2. Derive one deterministic Studio runtime publication snapshot at startup and expose it over HTTP.
+
+Recommended shape:
+
+- keep action metadata validation and ordering in `apps/server/src/lib/server.ts`
+- add a server-side Studio publication helper in a new file such as `apps/server/src/lib/studio-bootstrap.ts`
+- export any new server-owned route contract helpers from `apps/server/src/index.ts`
+- keep runtime artifact generation in `@mdcms/studio`; server depends on that package to publish the built artifact
+
+This keeps ownership clean:
+
+- `@mdcms/shared`: contract types and validators
+- `@mdcms/studio`: runtime artifact builder
+- `@mdcms/server`: HTTP routes, startup publication, filtering, and asset serving
+
+## Data Flow
+
+Server startup flow:
+
+1. Load server modules through the strict bootstrap path.
+2. Collect server actions from the loaded module report.
+3. Validate and sort the action catalog deterministically by `id`.
+4. Build one Studio runtime artifact set using the existing builder, producing:
+   - `manifest`
+   - `buildId`
+   - `entryFile`
+   - `entryPath`
+   - `entryUrl`
+5. Cache that Studio publication snapshot in server memory for request handling.
+
+Request flow:
+
+- `GET /api/v1/actions`
+  - returns the filtered deterministic list of action catalog items
+- `GET /api/v1/actions/:id`
+  - returns one filtered action item or `NOT_FOUND`
+- `GET /api/v1/studio/bootstrap`
+  - returns the cached validated `StudioBootstrapManifest`
+- `GET /api/v1/studio/assets/:buildId/*`
+  - serves only files under the cached immutable artifact root for the current `buildId`
+
+The server should not rebuild the runtime artifact on every request. Publication happens once at startup and request handlers read the prepared snapshot.
+
+## Visibility and Authorization Handling
+
+The current action metadata contract exposes advisory `permissions`, plus optional `studio` and `cli` visibility metadata. It does not define a full executable authorization model for catalog filtering.
+
+For `CMS-34`, the server should keep action visibility filtering injectable and deterministic:
+
+- continue using `isActionVisible` in `createServerRequestHandler(...)`
+- ensure list/detail responses use the same filtering decision
+- avoid adding new action contract fields or embedding executable metadata
+
+This keeps the backend contract aligned with the current spec and leaves stricter policy evolution to later auth/runtime tasks.
+
+## Failure Model
+
+Startup failures:
+
+- invalid action catalog item shape fails startup
+- duplicate action IDs fail startup
+- invalid Studio bootstrap manifest fails startup
+- missing Studio runtime artifact output fails startup
+
+Request failures:
+
+- `/api/v1/actions/:id` returns `404` for missing or filtered actions
+- `/api/v1/studio/bootstrap` returns `404` only when no runtime publication is available
+- `/api/v1/studio/assets/:buildId/*` returns `404` for unknown build IDs or missing files
+
+Error envelopes should remain normalized through existing server error handling.
+
+## Files In Scope
+
+Server runtime:
+
+- `apps/server/src/lib/server.ts`
+- `apps/server/src/lib/runtime-with-modules.ts`
+- `apps/server/src/lib/action-catalog-contract.ts`
+- `apps/server/src/lib/http-utils.ts`
+- `apps/server/src/index.ts`
+
+New server publication helper:
+
+- `apps/server/src/lib/studio-bootstrap.ts`
+- `apps/server/src/lib/studio-bootstrap.test.ts`
+
+Server verification:
+
+- `apps/server/src/lib/health.test.ts`
+- `apps/server/src/lib/runtime-with-modules.test.ts`
+
+Dependency and docs:
+
+- `apps/server/package.json`
+- `apps/server/README.md`
+- `packages/studio/README.md`
+
+## Test Strategy
+
+Server contract tests:
+
+- deterministic ordering for `/api/v1/actions`
+- detail lookup and hidden-action `404` behavior
+- inline request/response schema preservation in catalog payloads
+- `/api/v1/studio/bootstrap` response validates against shared manifest contract
+- bootstrap manifest always reports `mode: "module"`
+- `/api/v1/studio/assets/:buildId/*` serves the expected immutable file for the active build
+- mismatched build IDs and missing asset paths return `404`
+
+Runtime integration tests:
+
+- module probe routes remain mounted and reachable
+- `createServerRequestHandlerWithModules(...)` still surfaces the bundled module actions
+- server startup prepares one runtime publication snapshot and exposes it through the endpoint layer
+
+## Documentation
+
+Document at point of use:
+
+- `apps/server/README.md` should describe the new Studio runtime publication endpoints and deterministic asset semantics
+- `packages/studio/README.md` should note that runtime artifacts are now published by the server while loader execution remains deferred to CMS-60
+
+## Constraints
+
+- `docs/plans/` is local-only in this repository and must remain untracked
+- the brainstorming skill normally wants the design doc committed, but repository policy forbids committing `docs/plans/`
+- no Studio loader/runtime execution work should be pulled forward from CMS-60

+Conclusion: none of the remaining Week 2 items are currently blocked by the obvious upstream dependencies outside Week 2.
+
+## Recommended Completion Order
+
+### Recommended Single-Thread Sequence
+
+If one team is mainly finishing these serially, this is the cleanest order:
+
+1. CMS-33
+2. CMS-34
+3. CMS-35
+4. CMS-27
+5. CMS-25
+6. CMS-26
+7. CMS-28
+8. CMS-29
+9. CMS-32
+10. CMS-40
+11. CMS-41
+12. CMS-52
+
+### Why This Order
+
+1. **Finish the extensibility chain first (`CMS-33 -> CMS-34 -> CMS-35`).**
+   This is the tightest unfinished dependency chain in Week 2 and it has the highest downstream leverage. `CMS-34` is a platform surface that later Studio and CLI work depends on. Closing this chain early stabilizes module loading, action catalog behavior, and the Studio bootstrap contract before more features stack on top.
+
+2. **Lock the content API contract before adding the remaining behavior (`CMS-27`).**
+   `CMS-27` standardizes the envelope and pagination metadata across content APIs. Doing that early reduces rework in tests and client-facing responses while finishing the rest of content core.
+
+3. **Complete the remaining content behavior in dependency order (`CMS-25`, `CMS-26`, `CMS-28`, `CMS-29`).**
+   `CMS-25` closes the published-vs-draft read semantics. `CMS-26` must land before `CMS-28`. `CMS-29` is independent once the write path exists and should be completed before the content test gate so mismatch protections are covered in the final behavior set.
+
+4. **Run the integration gate only after the content surface is actually stable (`CMS-32`).**
+   Formally, `CMS-32` depends on `CMS-21..CMS-27`. Even so, it is better to schedule it after `CMS-28` and `CMS-29` as well, so the suite reflects the near-final content model and avoids a second round of integration test churn.
+
+5. **Then finish the narrower verticals (`CMS-40 -> CMS-41`, then `CMS-52`).**
+   `CMS-40` and `CMS-41` are a self-contained auth chain with no unresolved upstream blockers. `CMS-52` is also isolated because `CMS-51` is already done. These should follow once the broader platform and content contracts are less likely to shift under them.
+
+## Recommended Parallel Execution Plan
+
+If the team can run multiple tracks at once, this is the better delivery plan:
+
+### Track A: Extensibility Foundation
+
+1. CMS-33
+2. CMS-34
+3. CMS-35
+
+Why:
+
+- Strict dependency chain
+- High downstream fan-out into later Studio and CLI work
+- Best candidate for concentrated ownership by one engineer/pair
+
+### Track B: Content Core Closure
+
+1. CMS-27
+2. CMS-25
+3. CMS-26
+4. CMS-28
+5. CMS-29
+6. CMS-32
+
+Why:
+
+- `CMS-27` locks response contracts first
+- `CMS-26` is needed before `CMS-28`
+- `CMS-32` is the gate and should be last in the track
+
+### Track C: Auth Integrations
+
+1. CMS-40
+2. CMS-41
+
+Why:
+
+- Clean two-step dependency chain
+- No current cross-track blocker after `CMS-36`
+- Can proceed independently while platform/content work continues
+
+### Track D: Editor Completion
+
+1. CMS-52
+
+Why:
+
+- Only depends on `CMS-51`, which is already done
+- Narrow surface area
+- Safe to run in parallel unless editor contract changes are expected from unresolved platform work
+
+## Suggested Near-Term Milestone
+
+The most useful near-term checkpoint is:
+
+1. `CMS-33`, `CMS-34`, `CMS-35` complete
+2. `CMS-27`, `CMS-25`, `CMS-26`, `CMS-28`, `CMS-29` complete
+3. `CMS-32` green and gating
+
+That checkpoint would leave Week 2 with:
+
+- Extensibility closed
+- Content core closed and regression-gated
+- Only the auth integration pair (`CMS-40`, `CMS-41`) and the final editor MDX enhancement (`CMS-52`) still open
+
+## Short Recommendation
+
+If the goal is to reduce future rework, finish the **extensibility chain first**, then close the **remaining content contract and behavior work**, and only after that spend cycles on **OIDC/SAML** and **MDX editor** completion. If the team has parallel capacity, run **OIDC/SAML** and **CMS-52** beside the main platform/content work instead of waiting for them.

+# CMS-27 Response Envelope Design
+
+## Summary
+
+CMS-27 standardizes content API response envelopes and pagination metadata.
+The existing `/api/v1/content` list route already returns the target shape, but
+`GET /api/v1/content/:documentId/versions` still returns a bare `{ data: [] }`
+payload in the owning content spec and server implementation.
+
+The approved design treats the versions history endpoint as an in-scope list
+response for CMS-27. It will adopt the same pagination contract as
+`GET /api/v1/content`:
+
+- `limit` default `20`
+- `limit` max `100`
+- `offset` default `0`
+- success envelope `{ data, pagination: { total, limit, offset, hasMore } }`
+- newest-first version ordering remains unchanged
+
+## Spec Delta
+
+- Update `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
+  so `GET /api/v1/content/:documentId/versions` accepts `limit` and `offset`.
+- Change that endpoint's success contract from
+  `{ data: DocumentVersionSummary[] }` to
+  `{ data: DocumentVersionSummary[], pagination: { total, limit, offset, hasMore } }`.
+- Keep the shared list-envelope guidance in
+  `docs/specs/SPEC-005-auth-authorization-and-request-routing.md` unchanged.
+
+## Architecture
+
+The implementation stays scoped to content APIs but extracts the content-facing
+response types into `@mdcms/shared` so the server and CLI stop duplicating
+contract shapes.
+
+Add a new shared contract module for:
+
+- `ApiDataEnvelope<T>`
+- `ApiPaginatedEnvelope<T>`
+- `PaginationMetadata`
+- `ContentDocumentResponse`
+- `ContentVersionSummaryResponse`
+- `ContentVersionDocumentResponse`
+
+These remain type-only exports. Runtime route ownership, parsing, and
+authorization stay in `@mdcms/server`.
+
+## Server Changes
+
+- Update the content store interface so `listVersions(...)` returns
+  `{ rows, total, limit, offset }`, matching the existing `list(...)` contract.
+- Parse `limit` and `offset` for the versions listing route with the same
+  validation rules already used for `/api/v1/content`.
+- Add a small route-local helper for building the standard paginated envelope.
+- Keep single-document routes shaped as `{ data: ... }`, but type them against
+  the shared content response contracts.
+
+## Store Changes
+
+Both content store implementations must paginate version history after applying
+the existing newest-first sort:
+
+- `apps/server/src/lib/content-api/in-memory-store.ts`
+- `apps/server/src/lib/content-api/database-store.ts`
+
+Each store should return:
+
+- `rows`
+- `total`
+- `limit`
+- `offset`
+
+No persistence schema changes are required.
+
+## Consumer Changes
+
+`apps/cli/src/lib/pull.ts` and `apps/cli/src/lib/push.ts` currently duplicate
+content API payload shapes. They should import the shared content response
+types where those shapes already match current server behavior.
+
+This keeps CMS-27 scoped to content contracts without turning the task into a
+monorepo-wide response abstraction effort.
+
+## Error Handling
+
+No error semantics change in CMS-27:
+
+- invalid `limit` or `offset` stays `INVALID_QUERY_PARAM` (`400`)
+- missing document stays `NOT_FOUND` (`404`)
+- target-routing and authorization failures stay unchanged
+
+The task changes envelope consistency and pagination metadata only.
+
+## Testing
+
+Add or update contract coverage for:
+
+- versions list response envelope shape
+- versions pagination defaults
+- versions pagination with custom `limit` and `offset`
+- `hasMore` computation
+
+Keep existing content single-document response assertions aligned with the
+shared content response type definitions.
+
+## Documentation
+
+Document the public contract changes in:
+
+- `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
+- `apps/server/README.md`
+
+`docs/plans/` is local-only in this repository, so this design note is not
+intended to be committed.

+# CMS-27 Response Envelope Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Standardize content API response contracts for CMS-27 by adding shared content envelope types and paginating the versions history list endpoint.
+
+**Architecture:** Keep behavior ownership in `@mdcms/server`, but move the content API response shapes into `@mdcms/shared` so server and CLI consumers use one canonical contract. Extend `GET /api/v1/content/:documentId/versions` to use the same `limit`/`offset` and `{ data, pagination }` envelope rules as the main content list endpoint.
+
+**Tech Stack:** Bun, Nx, TypeScript, Zod, Elysia-style route handlers, Drizzle, Bun test
+
+---
+
+### Task 1: Lock The Spec And Shared Contract Surface
+
+**Files:**
+
+- Create: `packages/shared/src/lib/contracts/content-api.ts`
+- Modify: `packages/shared/src/index.ts`
+- Modify: `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
+- Test: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Write the failing test**
+
+Update the versions-list contract assertion in `apps/server/src/lib/content-api.test.ts` so it expects:
+
+```ts
+assert.equal(Array.isArray(versionsBody.data), true);
+assert.deepEqual(versionsBody.pagination, {
+  total: 1,
+  limit: 20,
+  offset: 0,
+  hasMore: false,
+});
+```
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun --cwd apps/server test ./src/lib/content-api.test.ts`
+Expected: FAIL because `GET /api/v1/content/:documentId/versions` currently returns no `pagination` field.
+
+**Step 3: Write minimal implementation**
+
+Create `packages/shared/src/lib/contracts/content-api.ts` with the canonical content response types:
+
+```ts
+export type ApiDataEnvelope<T> = { data: T };
+
+export type PaginationMetadata = {
+  total: number;
+  limit: number;
+  offset: number;
+  hasMore: boolean;
+};
+
+export type ApiPaginatedEnvelope<T> = {
+  data: T[];
+  pagination: PaginationMetadata;
+};
+```
+
+Also export content-specific response shapes from that module and re-export it from `packages/shared/src/index.ts`. Update `SPEC-003` so the versions listing endpoint explicitly accepts `limit`/`offset` and returns the paginated envelope.
+
+**Step 4: Run test to verify it still fails for the right reason**
+
+Run: `bun --cwd apps/server test ./src/lib/content-api.test.ts`
+Expected: FAIL remains isolated to route/store behavior, with shared contract types and spec text now in place.
+
+**Step 5: Commit**
+
+```bash
+git add packages/shared/src/lib/contracts/content-api.ts packages/shared/src/index.ts docs/specs/SPEC-003-content-storage-versioning-and-migrations.md apps/server/src/lib/content-api.test.ts
+git commit -m "feat: define shared content response contracts"
+```
+
+### Task 2: Paginate The Versions Route And In-Memory Store
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api/types.ts`
+- Modify: `apps/server/src/lib/content-api/routes.ts`
+- Modify: `apps/server/src/lib/content-api/in-memory-store.ts`
+- Modify: `apps/server/src/lib/content-api/responses.ts`
+- Test: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Write the failing test**
+
+Extend `apps/server/src/lib/content-api.test.ts` with a versions-pagination scenario that creates multiple published versions and asserts:
+
+```ts
+const response = await handler(
+  new Request(
+    `http://localhost/api/v1/content/${created.data.documentId}/versions?limit=1&offset=1`,
+    { headers: scopeHeaders },
+  ),
+);
+
+assert.equal(response.status, 200);
+assert.equal(body.data.length, 1);
+assert.equal(body.pagination.total, 3);
+assert.equal(body.pagination.limit, 1);
+assert.equal(body.pagination.offset, 1);
+assert.equal(body.pagination.hasMore, true);
+assert.equal(body.data[0]?.version, 2);
+```
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun --cwd apps/server test ./src/lib/content-api.test.ts`
+Expected: FAIL because the versions route ignores `limit`/`offset` and returns an array without pagination metadata.
+
+**Step 3: Write minimal implementation**
+
+- Change `listVersions(...)` in `apps/server/src/lib/content-api/types.ts` to return:
+
+```ts
+Promise<{
+  rows: ContentVersionSummary[];
+  total: number;
+  limit: number;
+  offset: number;
+}>;
+```
+
+- In `apps/server/src/lib/content-api/routes.ts`, parse `limit` and `offset` from the query and return:
+
+```ts
+{
+  data: versions.rows.map((version) => toVersionSummaryResponse(version)),
+  pagination: {
+    total: versions.total,
+    limit: versions.limit,
+    offset: versions.offset,
+    hasMore: versions.offset + versions.limit < versions.total,
+  },
+}
+```
+
+- In `apps/server/src/lib/content-api/in-memory-store.ts`, sort versions newest-first, slice by `offset` and `limit`, and return metadata with `rows`.
+- In `apps/server/src/lib/content-api/responses.ts`, type the response mappers against the new shared contract types.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun --cwd apps/server test ./src/lib/content-api.test.ts`
+Expected: PASS for the updated envelope and pagination assertions in the in-memory-backed handler tests.
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/content-api/types.ts apps/server/src/lib/content-api/routes.ts apps/server/src/lib/content-api/in-memory-store.ts apps/server/src/lib/content-api/responses.ts apps/server/src/lib/content-api.test.ts
+git commit -m "feat: paginate content version history responses"
+```
+
+### Task 3: Match The Database Store And CLI Consumers To The Shared Contract
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api/database-store.ts`
+- Modify: `apps/cli/src/lib/pull.ts`
+- Modify: `apps/cli/src/lib/push.ts`
+- Test: `apps/server/src/lib/content-api.test.ts`
+- Test: `apps/cli/src/lib/pull.test.ts`
+- Test: `apps/cli/src/lib/push.test.ts`
+
+**Step 1: Write the failing test**
+
+Add a DB-backed versions listing assertion in `apps/server/src/lib/content-api.test.ts` that exercises the existing database store path and expects paginated metadata for the versions endpoint. Also switch CLI test fixtures and parsing call sites to the shared response types so type errors surface during test/typecheck.
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun --cwd apps/server test ./src/lib/content-api.test.ts`
+Expected: FAIL in the DB-backed versions listing path because `database-store.ts` still returns a plain array.
+
+Run: `bun --cwd apps/cli test ./src/lib/pull.test.ts ./src/lib/push.test.ts`
+Expected: either PASS with type drift still unaddressed or FAIL/typecheck errors once shared types are wired into the CLI call sites.
+
+**Step 3: Write minimal implementation**
+
+- Update `apps/server/src/lib/content-api/database-store.ts` to return `{ rows, total, limit, offset }` for `listVersions(...)` after newest-first sort and slicing.
+- Replace the inline content payload and envelope types in `apps/cli/src/lib/pull.ts` and `apps/cli/src/lib/push.ts` with imports from `@mdcms/shared` where they match the current server contract.
+
+**Step 4: Run tests to verify they pass**
+
+Run: `bun --cwd apps/server test ./src/lib/content-api.test.ts`
+Expected: PASS for both in-memory and database-backed versions list pagination behavior.
+
+Run: `bun --cwd apps/cli test ./src/lib/pull.test.ts ./src/lib/push.test.ts`
+Expected: PASS with CLI consumers still parsing the standardized content contract correctly.
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/content-api/database-store.ts apps/cli/src/lib/pull.ts apps/cli/src/lib/push.ts apps/server/src/lib/content-api.test.ts apps/cli/src/lib/pull.test.ts apps/cli/src/lib/push.test.ts
+git commit -m "refactor: reuse shared content API contracts"
+```
+
+### Task 4: Update Operator Docs And Run Full Verification
+
+**Files:**
+
+- Modify: `apps/server/README.md`
+- Test: `package.json` workspace scripts
+
+**Step 1: Write the doc update**
+
+Update `apps/server/README.md` so the content endpoint docs explicitly state:
+
+- `GET /api/v1/content/:documentId/versions` accepts `limit` and `offset`
+- versions history returns `{ data, pagination }`
+- default `limit` is `20` and max `100`
+
+**Step 2: Run focused verification**
+
+Run: `bun --cwd apps/server test ./src/lib/content-api.test.ts`
+Expected: PASS
+
+Run: `bun --cwd packages/shared test ./src`
+Expected: PASS
+
+Run: `bun --cwd apps/cli test ./src/lib/pull.test.ts ./src/lib/push.test.ts`
+Expected: PASS
+
+**Step 3: Run workspace verification**
+
+Run: `bun run format:check`
+Expected: PASS
+
+Run: `bun run check`
+Expected: PASS
+
+**Step 4: Confirm git hygiene**
+
+Run: `git status --short`
+Expected: modified task files only; local-only paths such as `AGENTS.md`, `ROADMAP_TASKS.md`, `.codex/`, `.claude/`, and `docs/plans/` must not be staged.
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/README.md
+git commit -m "docs: document paginated content version responses"
+```

+# CMS-35 Contract Validation Suite Design
+
+**Task:** CMS-35 - Contract validation suite for extensibility
+
+**Date:** 2026-03-16
+
+## Scope Baseline
+
+Owning specs:
+
+- `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
+- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+- `docs/specs/README.md`
+
+Roadmap source:
+
+- `ROADMAP_TASKS.md` (`CMS-35`)
+
+No spec delta is required for this task. CMS-35 hardens existing extensibility
+contracts and registry behavior already defined in the owning specs.
+
+## Goal
+
+Add a CI-gated, fixture-driven contract validation suite for extensibility that:
+
+- validates module manifests, action catalog payloads, and Studio bootstrap
+  manifests with positive and negative fixtures
+- proves deterministic ordering and fail-fast collision behavior for server and
+  CLI registries
+- covers authorization-filtered action catalog behavior without pulling the full
+  Studio loader into scope
+- keeps failure output actionable for contributors and operators
+
+## In Scope
+
+- Contract validation for:
+  - `ModuleManifest`
+  - `ActionCatalogItem[]`
+  - `StudioBootstrapManifest`
+- Deterministic ordering tests for:
+  - server module loading and action collection
+  - CLI module loading and merged aliases/formatters/hooks
+- Collision tests for:
+  - duplicate module IDs
+  - duplicate action IDs
+  - conflicting server action routes via `(method, path)` collisions
+- Studio bootstrap publication verification for:
+  - manifest shape
+  - compatibility bounds
+  - asset-byte integrity against `integritySha256`
+  - placeholder signature/key invariants used by the current builder
+- Authorization coverage for:
+  - hidden actions omitted from `/api/v1/actions`
+  - hidden actions omitted from `/api/v1/actions/:id`
+  - forced access still rejected by protected server routes
+
+## Out Of Scope
+
+- Full `@mdcms/studio` runtime loader implementation
+- Loader-side network fetch and runtime execution
+- Runtime fallback / rollback / kill-switch behavior
+- Final production integrity/signature enforcement behavior for runtime loading
+- New extensibility surface contracts beyond those already owned by `SPEC-002`
+  and `SPEC-006`
+
+Those behaviors remain scheduled for later work, especially CMS-60 through
+CMS-62.
+
+## Chosen Approach
+
+Use a fixture-driven contract suite with one small pure verification helper for
+Studio bootstrap publications.
+
+Why this approach:
+
+- It matches CMS-35 acceptance criteria more directly than scattered ad hoc
+  tests.
+- It keeps CMS-35 in Phase 2 without dragging in loader/runtime execution.
+- It creates reusable validation seams that later Studio loader tasks can call
+  instead of re-deriving integrity and compatibility checks.
+
+## Package Responsibilities
+
+### `packages/shared`
+
+- Own manifest and action-catalog contract fixtures/tests.
+- Extend module planner collision detection to include duplicate server action
+  routes based on `(method, path)`.
+- Keep most fixtures local to tests unless a helper must be shared.
+
+### `packages/studio`
+
+- Add a pure bootstrap publication verifier.
+- Test valid and invalid bootstrap publications with deterministic fixtures.
+- Document that verification coverage exists before loader execution is added.
+
+### `apps/server`
+
+- Add server-facing tests for authorization-filtered action catalog behavior.
+- Add startup failure tests for duplicate action routes.
+
+### `apps/cli`
+
+- Prove deterministic merge order for CLI aliases, output formatters, and
+  preflight hooks across shuffled module inputs.
+
+### `packages/modules`
+
+- No production changes expected unless a very small test helper becomes
+  necessary.
+
+## Route Collision Interpretation
+
+CMS-35 acceptance requires collision coverage for conflicting routes, but the
+current extensibility contract does not expose an independent route manifest for
+arbitrary `mount()` behavior.
+
+To keep scope aligned with existing contracts, CMS-35 interprets route
+collisions as duplicate server action route declarations:
+
+- same HTTP method
+- same action `path`
+
+This covers the route metadata the extensibility system already owns without
+inventing a broader route-introspection contract.
+
+## Verification Strategy
+
+Planned validation flow:
+
+- `packages/shared` unit tests validate positive and negative contract fixtures.
+- `packages/shared` and app-level module-loader tests validate deterministic
+  ordering and collision reporting.
+- `packages/studio` unit tests validate bootstrap publication verification with
+  positive and negative fixtures.
+- Existing package `bun test ./src` targets remain the CI entrypoint; no new CI
+  orchestration layer is introduced in CMS-35.
+
+## Operator / Contributor Output
+
+Failure output should remain explicit about:
+
+- which manifest/action/bootstrap payload failed
+- which module or action caused the collision
+- which `(method, path)` route pair is duplicated
+- which integrity/signature/compatibility condition failed
+
+The suite should favor deterministic ordering of violations so failures are
+stable across repeated runs.

+# CMS-35 Contract Validation Suite Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add a CI-gated extensibility contract suite for module manifests, action catalog payloads, Studio bootstrap publications, and deterministic server/CLI registry behavior without implementing the full Studio loader.
+
+**Architecture:** Keep contract ownership where it already lives. `@mdcms/shared` continues to own manifest and action-catalog validators plus runtime module planning. `@mdcms/studio` adds a pure bootstrap publication verifier for build outputs. `@mdcms/server` and `@mdcms/cli` extend tests around authorization-filtering, route collisions, and deterministic registry merging without introducing new runtime/plugin abstractions.
+
+**Tech Stack:** Bun, Nx, TypeScript, Bun test, Elysia, Zod
+
+---
+
+### Task 1: Shared Contract Fixtures And Route Collision Detection
+
+**Files:**
+
+- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
+- Modify: `packages/shared/src/lib/contracts/action-catalog.test.ts`
+- Modify: `packages/shared/src/lib/runtime/module-loader-core.ts`
+- Modify: `packages/shared/src/lib/runtime/module-loader-core.test.ts`
+- Optional create: `packages/shared/src/lib/contracts/extensibility-test-fixtures.ts`
+
+**Step 1: Add positive and negative manifest fixtures**
+
+Add fixture values that cover:
+
+- valid manifest
+- empty `id`
+- invalid `apiVersion`
+- duplicate `dependsOn`
+- invalid semver bounds
+- inverted `minCoreVersion` / `maxCoreVersion`
+
+Keep fixtures local to tests unless re-use between multiple test files becomes noisy.
+
+**Step 2: Add positive and negative action catalog fixtures**
+
+Add fixture values that cover:
+
+- valid flattened metadata
+- invalid `permissions`
+- invalid `studio.form.mode`
+- invalid `cli.inputMode`
+- non-object `requestSchema`
+- non-object `responseSchema`
+- invalid list entries in array payloads
+
+**Step 3: Extend runtime module planning to detect route collisions**
+
+Update `buildRuntimeModulePlan(...)` in `packages/shared/src/lib/runtime/module-loader-core.ts` to treat duplicate server action route declarations as bootstrap violations when two server actions share the same:
+
+- `method`
+- `path`
+
+Add a new deterministic violation code only if needed; otherwise reuse the existing violation structure with a route-specific details payload.
+
+**Step 4: Add deterministic route-collision tests**
+
+In `packages/shared/src/lib/runtime/module-loader-core.test.ts`, add tests proving:
+
+- duplicate route pairs fail planning
+- collisions are reported deterministically across repeated runs
+- duplicate action IDs and duplicate route pairs are both preserved in violation output
+
+**Step 5: Run the shared package tests**
+
+Run:
+
+```bash
+bun test ./packages/shared/src
+```
+
+Expected:
+
+- all existing shared tests pass
+- new contract and route-collision tests pass
+
+**Step 6: Commit checkpoint**
+
+```bash
+git add packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/src/lib/contracts/action-catalog.test.ts packages/shared/src/lib/runtime/module-loader-core.ts packages/shared/src/lib/runtime/module-loader-core.test.ts
+git commit -m "test(shared): add extensibility contract fixtures"
+```
+
+Do not stage `docs/plans/` because repository rules keep those files untracked.
+
+### Task 2: Server And CLI Registry Regression Coverage
+
+**Files:**
+
+- Modify: `apps/server/src/lib/module-loader.test.ts`
+- Modify: `apps/server/src/lib/runtime-with-modules.test.ts`
+- Modify: `apps/server/src/lib/health.test.ts`
+- Modify: `apps/cli/src/lib/module-loader.test.ts`
+- Modify: `apps/cli/src/lib/runtime-with-modules.test.ts`
+
+**Step 1: Add server route-collision startup tests**
+
+Extend `apps/server/src/lib/module-loader.test.ts` so server bootstrap fails when two modules expose distinct action IDs but the same `(method, path)` pair.
+
+Cover:
+
+- deterministic violation ordering
+- actionable error details containing the route pair and both owners where possible
+
+**Step 2: Add authorization-filter enforcement coverage**
+
+In `apps/server/src/lib/runtime-with-modules.test.ts` or `apps/server/src/lib/health.test.ts`, add a protected route fixture proving:
+
+- an unauthorized action is hidden from `/api/v1/actions`
+- the hidden action also returns `404` from `/api/v1/actions/:id`
+- forcing the actual route still fails by server authorization, proving visibility metadata is advisory only
+
+Prefer a local test route with an explicit `authorize` gate instead of altering production module behavior.
+
+**Step 3: Expand CLI deterministic merge-order coverage**
+
+In CLI tests, prove merged:
+
+- `actionAliases`
+- `outputFormatters`
+- `preflightHooks`
+
+stay stable when input modules are shuffled but dependencies require a specific load order.
+
+**Step 4: Run targeted server and CLI tests**
+
+Run:
+
+```bash
+bun test ./apps/server/src/lib/module-loader.test.ts
+bun test ./apps/server/src/lib/runtime-with-modules.test.ts
+bun test ./apps/server/src/lib/health.test.ts
+bun test ./apps/cli/src/lib/module-loader.test.ts
+bun test ./apps/cli/src/lib/runtime-with-modules.test.ts
+```
+
+Expected:
+
+- new route-collision and authorization tests pass
+- deterministic ordering assertions stay stable
+
+**Step 5: Commit checkpoint**
+
+```bash
+git add apps/server/src/lib/module-loader.test.ts apps/server/src/lib/runtime-with-modules.test.ts apps/server/src/lib/health.test.ts apps/cli/src/lib/module-loader.test.ts apps/cli/src/lib/runtime-with-modules.test.ts
+git commit -m "test(server-cli): harden extensibility registry coverage"
+```
+
+### Task 3: Studio Bootstrap Publication Verification
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/build-runtime.ts`
+- Modify: `packages/studio/src/lib/build-runtime.test.ts`
+- Modify: `packages/studio/src/index.ts`
+- Modify: `packages/studio/README.md`
+- Optional create: `packages/studio/src/lib/bootstrap-verification.ts`
+
+**Step 1: Add a pure bootstrap publication verifier**
+
+Implement a helper that accepts:
+
+- a `StudioBootstrapManifest`
+- the built runtime bytes
+- expected loader compatibility input
+
+It should validate:
+
+- manifest shape
+- compatibility fields
+- `integritySha256` matches asset bytes
+- placeholder signature/key format remains internally consistent for the current builder
+
+This helper must not fetch URLs or execute runtime code.
+
+**Step 2: Add positive and negative bootstrap fixtures**
+
+Cover:
+
+- valid publication
+- incompatible `minStudioPackageVersion`
+- incompatible `minHostBridgeVersion`
+- integrity mismatch from mutated runtime bytes
+- invalid placeholder signature
+- invalid placeholder key id
+- invalid manifest shape
+
+**Step 3: Export only if genuinely useful**
+
+If later tasks will clearly re-use the helper, export it through `packages/studio/src/index.ts`. Otherwise keep it internal to avoid widening public API unnecessarily.
+
+**Step 4: Document the verification boundary**
+
+Update `packages/studio/README.md` to state:
+
+- build outputs now have contract verification coverage
+- loader-side fetch/execution is still deferred to CMS-60+
+
+**Step 5: Run studio tests**
+
+Run:
+
+```bash
+bun test ./packages/studio/src
+```
+
+Expected:
+
+- existing Studio tests pass
+- bootstrap publication verification tests pass
+
+**Step 6: Commit checkpoint**
+
+```bash
+git add packages/studio/src/lib/build-runtime.ts packages/studio/src/lib/build-runtime.test.ts packages/studio/src/index.ts packages/studio/README.md
+git commit -m "test(studio): verify bootstrap publications"
+```
+
+### Task 4: Workspace Verification And Completion
+
+**Files:**
+
+- No new code files expected
+
+**Step 1: Run task-specific verification**
+
+Run:
+
+```bash
+bun test ./packages/shared/src
+bun test ./apps/server/src
+bun test ./apps/cli/src
+bun test ./packages/studio/src
+```
+
+Expected:
+
+- all touched package tests pass
+- no new flaky behavior appears
+
+**Step 2: Run required workspace validation**
+
+Run:
+
+```bash
+bun run format:check
+bun run check
+```
+
+Expected:
+
+- formatting check passes
+- build and typecheck pass across the workspace
+
+**Step 3: Inspect git status**
+
+Run:
+
+```bash
+git status --short
+```
+
+Expected:
+
+- only task-scoped source changes are staged or modified
+- local-only paths remain unstaged and uncommitted:
+  - `.claude/`
+  - `.codex/`
+  - `AGENTS.md`
+  - `CLAUDE.md`
+  - `ROADMAP_TASKS.md`
+  - `EXTENSIBILITY_APPROACH_COMPARISON.md`
+  - `mcp_servers.json`
+  - `docs/plans/`
+
+**Step 4: Final commit**
+
+```bash
+git add packages/shared/src apps/server/src apps/cli/src packages/studio/src packages/studio/README.md

+# CMS-25 Published-Default Reads Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Enforce the CMS-25 visibility contract so content reads default to published snapshots, draft reads require `draft=true`, and draft list reads do not leak deleted documents unless explicitly requested.
+
+**Architecture:** Keep the existing route-level `draft=true` scope selection and published-vs-draft read split, but centralize list-visibility rules so the in-memory and database stores apply the same behavior. Drive the change with server contract tests first, then refactor the shared filtering logic with the narrowest production diff needed to satisfy the spec.
+
+**Tech Stack:** Bun, TypeScript, Node test runner, Elysia route handlers, Drizzle ORM, postgres.js
+
+---
+
+### Task 1: Lock the visibility contract with failing tests
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api.test.ts`
+- Modify: `apps/server/src/lib/auth.test.ts`
+
+**Step 1: Write the failing test**
+
+Add focused tests that prove:
+
+- `GET /api/v1/content` returns only published snapshots by default.
+- `GET /api/v1/content?draft=true` returns mutable heads for published and unpublished docs.
+- `GET /api/v1/content?draft=true` excludes deleted docs unless `isDeleted=true` is explicitly requested.
+- API-key list reads require `content:read:draft` when `draft=true`.
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts apps/server/src/lib/auth.test.ts`
+Expected: FAIL because draft list reads currently include deleted rows and/or missing list-level auth coverage is not enforced by tests yet.
+
+**Step 3: Write minimal implementation**
+
+Do not change production code in this task.
+
+**Step 4: Run test to verify it still fails for the intended reason**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts apps/server/src/lib/auth.test.ts`
+Expected: FAIL with the new visibility-contract assertion, not with a malformed test.
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/content-api.test.ts apps/server/src/lib/auth.test.ts
+git commit -m "test(server): add CMS-25 visibility contract coverage"
+```
+
+### Task 2: Refactor read visibility across both stores
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api/database-store.ts`
+- Modify: `apps/server/src/lib/content-api/in-memory-store.ts`
+- Modify: `apps/server/src/lib/content-api/types.ts`
+
+**Step 1: Write the failing test**
+
+Use the failing tests from Task 1 as the active red state. Do not add more production assumptions than those tests require.
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts apps/server/src/lib/auth.test.ts`
+Expected: FAIL on the CMS-25 visibility assertions.
+
+**Step 3: Write minimal implementation**
+
+Add a shared visibility decision for list reads that:
+
+- keeps published-default list behavior unchanged,
+- returns draft heads only when `draft=true`,
+- excludes deleted docs from draft list reads unless `isDeleted=true`,
+- still allows explicit `isDeleted=true/false` filtering for trash and non-trash views.
+
+Keep single-document behavior unchanged except where already covered by the existing spec/tests.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts apps/server/src/lib/auth.test.ts`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/content-api/database-store.ts apps/server/src/lib/content-api/in-memory-store.ts apps/server/src/lib/content-api/types.ts apps/server/src/lib/content-api.test.ts apps/server/src/lib/auth.test.ts
+git commit -m "feat(server): enforce CMS-25 draft visibility contract"
+```
+
+### Task 3: Verify task-scoped behavior and workspace health
+
+**Files:**
+
+- Modify: `apps/cli/src/lib/pull.test.ts` (only if the server contract change requires adjusted CLI assumptions)
+
+**Step 1: Write the failing test**
+
+Only if needed, add a CLI pull regression test showing that default pull still requests `draft=true` and published pull still requests published snapshots.
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test apps/cli/src/lib/pull.test.ts`
+Expected: FAIL only if a CLI regression or expectation mismatch is revealed.
+
+**Step 3: Write minimal implementation**
+
+Adjust CLI expectations only if the server contract refactor changes observable request semantics. Do not widen scope beyond CMS-25.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test apps/cli/src/lib/pull.test.ts`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add apps/cli/src/lib/pull.test.ts
+git commit -m "test(cli): keep pull aligned with CMS-25 visibility rules"
+```
+
+### Task 4: Final verification
+
+**Files:**
+
+- No code changes expected
+
+**Step 1: Run targeted verification**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts apps/server/src/lib/auth.test.ts apps/cli/src/lib/pull.test.ts`
+Expected: PASS
+
+**Step 2: Run workspace checks required by the repo workflow**
+
+Run: `bun run format:check`
+Expected: PASS
+
+Run: `bun run check`
+Expected: PASS
+
+**Step 3: Confirm local-only paths stay unstaged**
+
+Run: `git status --short`
+Expected: `docs/plans/`, `ROADMAP_TASKS.md`, `AGENTS.md`, and other local-only files remain untracked and unstaged.
+
+**Step 4: Commit**
+
+```bash
+git add <task-scoped files only>
+git commit -m "feat(server): complete CMS-25"
+```

+# CMS-26 Resolve Reference Expansion Design
+
+## Context
+
+CMS-26 owns `resolve=` reference expansion for content reads. The current owning
+content spec defines `resolve` only as a list query parameter, while the SDK
+docs already show `resolve` on single-document reads. The approved design for
+this task closes that gap and defines deterministic read-time behavior for
+missing or invalid references.
+
+## Approved Decisions
+
+### Endpoint Scope
+
+`resolve` is supported on every endpoint that returns a full content payload:
+
+- `GET /api/v1/content`
+- `GET /api/v1/content/:documentId`
+- `GET /api/v1/content/:documentId/versions/:version`
+
+`resolve` is not added to `GET /api/v1/content/:documentId/versions` because
+that endpoint returns summaries, not full document payloads.
+
+### Resolution Mode
+
+- Resolution is shallow only.
+- The server expands exactly the fields named in `resolve`.
+- The server does not recurse into references inside resolved documents.
+
+### Scope And Visibility
+
+- Resolution is always constrained to the explicit `(project, environment)`
+  request target.
+- Published reads resolve against published-visible targets.
+- `draft=true` reads resolve against draft-visible targets.
+- Version snapshot reads resolve referenced targets using published-visible
+  reads because that endpoint does not expose `draft=true`.
+
+### Response Shape
+
+- Requested reference fields are replaced inline in the returned payload.
+- Successfully resolved fields become embedded content document objects.
+- Unresolved fields become `null`.
+- Each returned document may include an optional top-level `resolveErrors` map.
+- `resolveErrors` keys use full field paths, for example
+  `frontmatter.author` or `frontmatter.hero.author`.
+- `resolveErrors` is omitted when there are no resolution failures.
+
+Recommended unresolved shape:
+
+```json
+{
+  "resolveErrors": {
+    "frontmatter.author": {
+      "code": "REFERENCE_NOT_FOUND",
+      "message": "Referenced document could not be resolved in the target project/environment.",
+      "ref": {
+        "documentId": "uuid",
+        "type": "Author"
+      }
+    }
+  }
+}
+```
+
+### Validation And Error Semantics
+
+- `resolve` accepts repeated query params or equivalent string-array forms.
+- Each requested field path must map to a reference field in the resolved schema
+  for the returned document type.
+- Unknown fields, non-reference fields, or fields excluded from the target
+  environment schema fail deterministically with `INVALID_QUERY_PARAM` (`400`).
+- Stored target type metadata remains enforced during expansion.
+- Read-time failures for secondary referenced targets do not fail the primary
+  content read. They yield `null` plus `resolveErrors`.
+- `resolveErrors[*].code` must distinguish at least:
+  - `REFERENCE_NOT_FOUND`
+  - `REFERENCE_DELETED`
+  - `REFERENCE_TYPE_MISMATCH`
+  - `REFERENCE_FORBIDDEN`
+
+## Required Spec Delta
+
+### SPEC-003
+
+Update the content spec to:
+
+- add `resolve` to `GET /api/v1/content/:documentId`
+- add `resolve` to `GET /api/v1/content/:documentId/versions/:version`
+- define shallow-only semantics
+- define top-level `resolveErrors`
+- define deterministic validation and unresolved-reference behavior
+
+### SPEC-008
+
+Keep the SDK example aligned with the now-normative contract for single-document
+reads using `resolve`.
+
+## Verification Expectations
+
+CMS-26 implementation should verify:
+
+- list, single-document, and immutable-version reads all honor the same
+  `resolve` contract
+- version-summary reads remain unchanged
+- published reads do not leak draft-only referenced content
+- `draft=true` reads can resolve draft-visible referenced content
+- invalid `resolve` paths fail with `INVALID_QUERY_PARAM`
+- missing, deleted, type-mismatched, and forbidden referenced targets produce
+  `null` plus `resolveErrors`
+- all reference expansion remains bound to the explicit routed environment
+
+## Notes
+
+This design note is local workspace documentation under `docs/plans/` and
+should remain untracked per repository rules.

+# CMS-26 Resolve Reference Expansion Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Implement shallow `resolve=` reference expansion across all full
+content read endpoints, with environment-scoped validation and deterministic
+`resolveErrors` metadata for unresolved targets.
+
+**Architecture:** Keep base content reads in the existing content store and add
+a dedicated server-side reference-resolution layer for read responses. Validate
+requested field paths against schema registry snapshots for the routed
+environment, fetch referenced targets through existing content-store reads, and
+surface failures as `null` plus top-level `resolveErrors` keyed by full field
+paths.
+
+**Tech Stack:** Bun, Nx, TypeScript, Elysia, Drizzle, Postgres, Zod, Node test
+
+---
+
+### Task 1: Update The Normative Contract
+
+**Files:**
+
+- Modify: `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
+- Modify: `docs/specs/SPEC-008-cli-and-sdk.md`
+- Modify: `packages/shared/src/lib/contracts/content-api.ts:17-56`
+
+**Step 1: Update the owning content spec**
+
+Add the approved `resolve` contract to the endpoint table and query-parameter
+sections in `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`.
+Document support for:
+
+- `GET /api/v1/content`
+- `GET /api/v1/content/:documentId`
+- `GET /api/v1/content/:documentId/versions/:version`
+
+Document these rules explicitly:
+
+- shallow-only resolution
+- top-level optional `resolveErrors`
+- full-path error keys
+- `null` for unresolved fields
+- `INVALID_QUERY_PARAM` for unknown/non-reference/excluded paths
+
+**Step 2: Align the SDK spec**
+
+Update `docs/specs/SPEC-008-cli-and-sdk.md` so its `cms.get(..., { resolve })`
+example and surrounding prose match the normative contract without adding any
+new SDK behavior beyond CMS-26.
+
+**Step 3: Extend the shared API response types**
+
+Update `packages/shared/src/lib/contracts/content-api.ts` so
+`ContentDocumentResponse` and `ContentVersionDocumentResponse` can carry
+optional resolution metadata:
+
+```ts
+export type ContentResolveError = {
+  code:
+    | "REFERENCE_NOT_FOUND"
+    | "REFERENCE_DELETED"
+    | "REFERENCE_TYPE_MISMATCH"
+    | "REFERENCE_FORBIDDEN";
+  message: string;
+  ref: {
+    documentId: string;
+    type: string;
+  };
+};
+
+export type ResolveErrorsMap = Record<string, ContentResolveError>;
+```
+
+Then add:
+
+```ts
+resolveErrors?: ResolveErrorsMap;
+```
+
+to the full-document response types only.
+
+**Step 4: Run typecheck**
+
+Run: `bun run typecheck`
+
+Expected: PASS for shared contract updates before server implementation begins.
+
+**Step 5: Commit**
+
+```bash
+git add docs/specs/SPEC-003-content-storage-versioning-and-migrations.md docs/specs/SPEC-008-cli-and-sdk.md packages/shared/src/lib/contracts/content-api.ts
+git commit -m "docs: define cms-26 resolve contract"
+```
+
+Do not stage or commit anything under `docs/plans/`.
+
+### Task 2: Add Failing CMS-26 Integration Coverage
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Write the failing tests**
+
+Add targeted DB-backed tests in `apps/server/src/lib/content-api.test.ts` for:
+
+- list reads resolve a valid reference inline
+- single-document reads accept `resolve` and resolve inline
+- immutable version reads accept `resolve` and resolve inline
+- `GET /api/v1/content/:documentId/versions` ignores `resolve` support and
+  remains summary-only
+- invalid `resolve` field path returns `INVALID_QUERY_PARAM`
+- non-reference `resolve` field path returns `INVALID_QUERY_PARAM`
+- missing referenced target returns `null` plus
+  `resolveErrors["frontmatter.author"].code === "REFERENCE_NOT_FOUND"`
+- deleted referenced target returns `REFERENCE_DELETED`
+- type mismatch between stored ref metadata and fetched target returns
+  `REFERENCE_TYPE_MISMATCH`
+- forbidden referenced target returns `REFERENCE_FORBIDDEN`
+- published reads do not expand draft-only referenced targets
+- `draft=true` reads can expand draft-visible referenced targets
+
+Seed schema registry entries with reference metadata in the test fixture, for
+example:
+
+```ts
+const resolvedSchema = {
+  type: "BlogPost",
+  directory: "content/blog",
+  localized: true,
+  fields: {
+    author: {
+      kind: "string",
+      required: false,
+      nullable: true,
+      reference: { targetType: "Author" },
+    },
+  },
+};
+```
+
+Also add at least one nested path fixture, such as `frontmatter.hero.author`,
+to verify full-path keys in `resolveErrors`.
+
+**Step 2: Run the targeted tests to verify they fail**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/content-api.test.ts --test-name-pattern "resolve|reference"
+```
+
+Expected: FAIL because the routes currently accept `resolve` only on list reads
+and do not perform any reference expansion.
+
+**Step 3: Commit the failing tests**
+
+```bash
+git add apps/server/src/lib/content-api.test.ts
+git commit -m "test: codify cms-26 resolve behavior"
+```
+
+### Task 3: Implement Query Parsing And Schema Path Validation
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api/types.ts:54-190`
+- Modify: `apps/server/src/lib/content-api/parsing.ts:1-240`
+- Create: `apps/server/src/lib/content-api/reference-resolution.ts`
+- Modify: `apps/server/src/lib/content-api.ts`
+- Modify: `apps/server/src/lib/runtime-with-modules.ts`
+- Modify: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Extend the route dependencies and query parsing**
+
+Update `apps/server/src/lib/content-api/types.ts` so route options can load the
+resolved schema for a type in the routed scope:
+
+```ts
+import type { SchemaRegistryTypeSnapshot } from "@mdcms/shared";
+
+export type ContentSchemaLookup = (
+  scope: ContentScope,
+  type: string,
+) => Promise<SchemaRegistryTypeSnapshot | undefined>;
+
+export type MountContentApiRoutesOptions = {
+  store: ContentStore;
+  authorize: ContentRequestAuthorizer;
+  requireCsrf: ContentRequestCsrfProtector;
+  getSchemaSnapshot: ContentSchemaLookup;
+};
+```
+
+In `apps/server/src/lib/content-api/parsing.ts`, add a parser that normalizes
+`resolve` from `string | string[] | undefined` into a deduplicated string array
+and rejects empty segments.
+
+**Step 2: Create the schema-aware resolver helpers**
+
+Create `apps/server/src/lib/content-api/reference-resolution.ts` with pure
+helpers to:
+
+- normalize field paths to full `frontmatter.*` paths
+- walk `SchemaRegistryTypeSnapshot.fields`
+- verify each requested path points at a reference field
+- extract `{ documentId, type }` from the stored reference value
+- build deterministic `RuntimeError` instances for invalid query paths
+
+Suggested shape:
+
+```ts
+export type ParsedResolveField = {
+  requestPath: string;
+  frontmatterPath: string;
+  segments: string[];
+  targetType: string;
+};
+
+export function parseResolveFields(
+  rawResolve: string | string[] | undefined,
+  schema: SchemaRegistryTypeSnapshot,
+): ParsedResolveField[] {
+  // normalize, validate, dedupe, throw INVALID_QUERY_PARAM on invalid input
+}
+```
+
+**Step 3: Wire schema lookup into the real server runtime**
+
+Update `apps/server/src/lib/runtime-with-modules.ts` so
+`mountContentApiRoutes()` receives `getSchemaSnapshot`. The callback should read
+`schema_registry_entries.resolved_schema` for the routed `(project, environment,
+type)` tuple using the existing database connection.
+
+Keep the `createHandler()` helper in `apps/server/src/lib/content-api.test.ts`
+working by passing a simple stub that returns `undefined` when tests do not
+exercise `resolve`.
+
+**Step 4: Run the targeted tests**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/content-api.test.ts --test-name-pattern "resolve|reference"
+```
+
+Expected: FAIL later in the flow because routes still do not perform reference
+expansion, but invalid-path cases should now be able to compile against the new
+helpers.
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/content-api/types.ts apps/server/src/lib/content-api/parsing.ts apps/server/src/lib/content-api/reference-resolution.ts apps/server/src/lib/content-api.ts apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/content-api.test.ts
+git commit -m "feat(server): add cms-26 resolve validation scaffolding"
+```
+
+### Task 4: Resolve References In Read Responses
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api/routes.ts:1-240`
+- Modify: `apps/server/src/lib/content-api/responses.ts:19-70`
+- Modify: `apps/server/src/lib/content-api/reference-resolution.ts`
+- Modify: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Write the response-level resolution flow**
+
+In `apps/server/src/lib/content-api/reference-resolution.ts`, add a helper that
+resolves requested references for a returned document by:
+
+- validating the root document schema
+- reading the stored ref payload from `frontmatter`
+- fetching the target through `store.getById(scope, documentId, { draft })`
+- authorizing secondary reads against the resolved target path
+- returning an updated document payload plus `resolveErrors`
+
+Suggested shape:
+
+```ts
+export async function resolveDocumentReferences(input: {
+  document: ContentDocument | ContentVersionDocument;
+  scope: ContentScope;
+  resolveFields: ParsedResolveField[];
+  draft: boolean;
+  getById: ContentStore["getById"];
+  authorizeDocumentPath: (path: string) => Promise<void>;
+}): Promise<{
+  frontmatter: Record<string, unknown>;
+  resolveErrors?: ResolveErrorsMap;
+}> {
+  // replace successful fields inline
+  // set null + resolveErrors for missing/deleted/type mismatch/forbidden
+}
+```
+
+Use full field paths like `frontmatter.author` and `frontmatter.hero.author`
+when populating `resolveErrors`.
+
+**Step 2: Apply resolution to all full-document read endpoints**
+
+Update `apps/server/src/lib/content-api/routes.ts` so these endpoints parse and
+apply `resolve`:
+
+- `GET /api/v1/content`
+- `GET /api/v1/content/:documentId`
+- `GET /api/v1/content/:documentId/versions/:version`
+
+Do not change `GET /api/v1/content/:documentId/versions`.
+
+For list reads, resolve each returned document independently after the primary
+authorization checks succeed. For immutable version reads, resolve referenced
+targets via published-mode reads.
+
+**Step 3: Serialize `resolveErrors`**
+
+Update `apps/server/src/lib/content-api/responses.ts` so
+`toDocumentResponse()` and `toVersionDocumentResponse()` include
+`resolveErrors` when present and omit it when absent.
+
+**Step 4: Run the targeted tests to verify they pass**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/content-api.test.ts --test-name-pattern "resolve|reference"
+```
+
+Expected: PASS for the new CMS-26 cases.
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/content-api/routes.ts apps/server/src/lib/content-api/responses.ts apps/server/src/lib/content-api/reference-resolution.ts apps/server/src/lib/content-api.test.ts
+git commit -m "feat(server): implement cms-26 reference expansion"
+```
+
+### Task 5: Verify Adjacent Behavior And Finish
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Add any missing regression coverage**
+
+Fill any remaining gaps found while implementing, especially:
+
+- published-default reads still behave like CMS-25
+- immutable version reads still return unchanged base snapshot fields
+- version-summary endpoint stays summary-only
+- non-`resolve` reads still omit `resolveErrors`
+
+**Step 2: Run the focused server test file**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/content-api.test.ts
+```
+
+Expected: PASS
+
+**Step 3: Run workspace validation required by repo policy**
+
+Run:
+
+```bash
+bun run format:check
+bun run check
+```
+
+Expected: PASS
+
+**Step 4: Inspect git status**
+
+Run:
+
+```bash
+git status --short
+```
+
+Expected:
+
+- code/spec files for CMS-26 are staged or committed as intended
+- local-only paths remain unstaged and untracked:
+  - `AGENTS.md`
+  - `ROADMAP_TASKS.md`
+  - `docs/plans/`
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/content-api.test.ts
+git commit -m "test: finalize cms-26 regression coverage"
+```
+
+Do not stage or commit anything under `docs/plans/`.

+# CMS-28 CMS-29 Reference Identity And Schema Hash Gate Design
+
+## Context
+
+CMS-28 and CMS-29 both land on the same write-path seam in the content API.
+CMS-28 needs reference fields to persist stable environment-local document
+identities, while CMS-29 needs the server to reject draft-content writes when
+the client's local schema hash is missing, unsynced, or stale for the target
+environment.
+
+The approved design combines both tasks so the schema gate runs before any
+write-side reference validation. That lets CMS-28 rely on a synced target
+schema instead of carrying a permissive fallback that CMS-29 would immediately
+remove.
+
+## Approved Decisions
+
+### Endpoint Scope
+
+Schema-hash gating applies only to:
+
+- `POST /api/v1/content`
+- `PUT /api/v1/content/:documentId`
+
+It does not apply to `DELETE`, `restore`, `restore version`, `publish`, or
+`unpublish`.
+
+### Transport
+
+Clients send the local schema hash in a dedicated header:
+
+```http
+x-mdcms-schema-hash: <schemaHash>
+```
+
+The hash is request metadata, not content data, so it stays out of JSON bodies.
+
+### Deterministic Errors
+
+- Missing or blank header returns `SCHEMA_HASH_REQUIRED` (`400`).
+- Missing target schema sync record returns `SCHEMA_NOT_SYNCED` (`409`).
+- Non-matching client and server hashes return `SCHEMA_HASH_MISMATCH` (`409`).
+
+Recommended detail payloads:
+
+- `SCHEMA_HASH_REQUIRED`: `{ field: "x-mdcms-schema-hash" }`
+- `SCHEMA_NOT_SYNCED`: `{ project, environment }`
+- `SCHEMA_HASH_MISMATCH`:
+  `{ project, environment, clientSchemaHash, serverSchemaHash }`
+
+### Stored Reference Shape
+
+The current spec set is inconsistent about whether stored reference values are
+plain IDs or rich objects. The approved contract resolves that in favor of the
+simpler shape:
+
+- stored `frontmatter` reference values are plain env-local `document_id` UUID
+  strings
+- target type metadata remains schema-owned through `reference("TypeName")`
+- read-time `resolve=` expansion still turns stored IDs into inline documents
+
+### Write Validation Order
+
+For `POST /api/v1/content` and `PUT /api/v1/content/:documentId`, the server
+must:
+
+1. resolve target routing
+2. authorize the request
+3. validate `x-mdcms-schema-hash`
+4. load the target environment's schema sync record
+5. reject `SCHEMA_HASH_REQUIRED`, `SCHEMA_NOT_SYNCED`, or
+   `SCHEMA_HASH_MISMATCH` when applicable
+6. load the target environment's resolved schema for the effective content type
+7. validate reference-bearing fields in `frontmatter`
+8. persist the draft content
+
+### Reference Validation Rules
+
+- Validation walks nested object fields and arrays recursively.
+- Only fields declared as `reference(...)` in the resolved schema receive
+  special validation.
+- Each stored reference value must be a UUID string that resolves to a
+  non-deleted document in the same routed `(project, environment)` scope.
+- The referenced document's type must match the schema-declared target type.
+- Invalid shape, malformed UUID, missing target, deleted target, out-of-scope
+  target, and type mismatch all fail the write with `INVALID_INPUT` (`400`).
+- If the effective content type does not exist in the target environment's
+  resolved schema, the write fails with `INVALID_INPUT` (`400`).
+- This combined work does not introduce full schema validation for every
+  non-reference field. It only hardens reference identity plus the schema-hash
+  write gate.
+
+## Required Spec Delta
+
+### SPEC-004
+
+Update `docs/specs/SPEC-004-schema-system-and-sync.md` to define the schema
+gate for content draft-write endpoints:
+
+- required `x-mdcms-schema-hash` header
+- `SCHEMA_HASH_REQUIRED` (`400`)
+- `SCHEMA_NOT_SYNCED` (`409`)
+- `SCHEMA_HASH_MISMATCH` (`409`)
+- gate runs before content validation and persistence
+- stored references are plain env-local `document_id` strings
+
+### SPEC-003
+
+Update `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md` to:
+
+- state that reference fields persist plain env-local `document_id` UUID
+  strings
+- keep `resolve=` as read-time expansion only
+- add `x-mdcms-schema-hash` to the `POST /api/v1/content` and
+  `PUT /api/v1/content/:documentId` request contracts
+- add `SCHEMA_HASH_REQUIRED`, `SCHEMA_NOT_SYNCED`, and
+  `SCHEMA_HASH_MISMATCH` to those endpoint tables
+- keep `INVALID_INPUT` (`400`) for reference-validation failures
+
+## Verification Expectations
+
+Implementation should verify:
+
+- create and update reject missing schema hash headers
+- create and update reject unsynced target environments
+- create and update reject mismatched client/server schema hashes
+- matching schema hashes allow writes to continue normally
+- reference writes accept valid env-local UUID strings
+- reference writes reject malformed UUIDs
+- reference writes reject missing, deleted, wrong-type, and out-of-scope targets
+- nested object references and arrays of references are both validated
+- existing `resolve=` read behavior continues to work with stored string IDs
+
+## Notes
+
+This design note is local workspace documentation under `docs/plans/` and
+should remain untracked per repository rules.

+# CMS-28 CMS-29 Reference Identity And Schema Hash Gate Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Implement CMS-28 and CMS-29 together so content create/update writes
+require a matching target-environment schema hash and persist reference fields
+as validated env-local `document_id` UUID strings.
+
+**Architecture:** Keep the schema-hash gate at the route layer because it is an
+HTTP contract keyed off request headers and target-environment sync state. Keep
+reference validation in reusable content-store helpers so DB-backed routes,
+in-memory tests, and future write flows all enforce the same storage contract
+after the schema gate passes.
+
+**Tech Stack:** Bun, Nx, TypeScript, Elysia, Drizzle, Postgres, Zod, Node test
+
+---
+
+### Task 1: Publish The Normative Contract
+
+**Files:**
+
+- Modify: `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
+- Modify: `docs/specs/SPEC-004-schema-system-and-sync.md`
+- Modify: `apps/server/README.md`
+
+**Step 1: Update the schema-system spec**
+
+Add the approved CMS-29 write-gate contract to
+`docs/specs/SPEC-004-schema-system-and-sync.md`. Document:
+
+- `x-mdcms-schema-hash` on `POST /api/v1/content`
+- `x-mdcms-schema-hash` on `PUT /api/v1/content/:documentId`
+- `SCHEMA_HASH_REQUIRED` (`400`)
+- `SCHEMA_NOT_SYNCED` (`409`)
+- `SCHEMA_HASH_MISMATCH` (`409`)
+- stored reference values are plain env-local `document_id` strings
+
+**Step 2: Update the content spec**
+
+Update `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md` so
+the reference section and endpoint table match the approved contract. Keep
+`resolve=` as read-time expansion only and keep `INVALID_INPUT` (`400`) as the
+reference-validation failure code.
+
+**Step 3: Update the point-of-use server docs**
+
+Add a short operator-facing note to `apps/server/README.md` covering:
+
+- required `x-mdcms-schema-hash` on content create/update
+- the three schema-gate errors
+- stored reference fields are env-local document ID strings
+
+**Step 4: Run format check for the doc edits**
+
+Run:
+
+```bash
+bun run format:check
+```
+
+Expected: PASS or only unrelated pre-existing failures outside these doc edits.
+
+**Step 5: Commit**
+
+```bash
+git add docs/specs/SPEC-003-content-storage-versioning-and-migrations.md docs/specs/SPEC-004-schema-system-and-sync.md apps/server/README.md
+git commit -m "docs: define cms-28 and cms-29 content write contract"
+```
+
+Do not stage or commit anything under `docs/plans/`.
+
+### Task 2: Add Failing Schema-Gate Coverage
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Add failing route tests for missing and stale schema state**
+
+Add DB-backed route tests in `apps/server/src/lib/content-api.test.ts` for:
+
+- missing `x-mdcms-schema-hash` returns `SCHEMA_HASH_REQUIRED`
+- missing target schema sync record returns `SCHEMA_NOT_SYNCED`
+- mismatched header and server hash returns `SCHEMA_HASH_MISMATCH`
+- matching hash allows create/update to proceed
+
+Reuse the existing schema-seeding helpers where possible, and add one helper
+that can seed a known `schemaHash` for the target environment.
+
+**Step 2: Run the targeted tests to verify they fail**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/content-api.test.ts --test-name-pattern "schema hash|SCHEMA_HASH|not synced"
+```
+
+Expected: FAIL because content writes do not currently read or enforce the
+schema-hash header.
+
+**Step 3: Commit the failing tests**
+
+```bash
+git add apps/server/src/lib/content-api.test.ts
+git commit -m "test: codify cms-29 schema hash gate"
+```
+
+### Task 3: Implement The Route-Level Schema Hash Gate
+
+**Files:**
+
+- Create: `apps/server/src/lib/content-api/schema-hash.ts`
+- Modify: `apps/server/src/lib/content-api/types.ts`
+- Modify: `apps/server/src/lib/content-api/parsing.ts`
+- Modify: `apps/server/src/lib/content-api/routes.ts`
+- Modify: `apps/server/src/lib/runtime-with-modules.ts`
+- Modify: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Add a schema-sync lookup contract for content routes**
+
+Extend `apps/server/src/lib/content-api/types.ts` with a route dependency that
+can read the current schema sync state for a routed scope:
+
+```ts
+export type ContentSchemaSyncState = {
+  schemaHash: string;
+};
+
+export type ContentSchemaSyncLookup = (
+  scope: ContentScope,
+) => Promise<ContentSchemaSyncState | undefined>;
+```
+
+Add `getSchemaSyncState` to `MountContentApiRoutesOptions`.
+
+**Step 2: Add header parsing helpers**
+
+In `apps/server/src/lib/content-api/parsing.ts`, add a small parser that reads
+`x-mdcms-schema-hash`, trims it, and returns `undefined` for missing values.
+Keep error creation in the gate helper so the parser stays generic.
+
+**Step 3: Implement the gate helper**
+
+Create `apps/server/src/lib/content-api/schema-hash.ts` with pure helpers to:
+
+- read `x-mdcms-schema-hash`
+- throw `SCHEMA_HASH_REQUIRED` (`400`) on missing/blank values
+- throw `SCHEMA_NOT_SYNCED` (`409`) when no sync state exists
+- throw `SCHEMA_HASH_MISMATCH` (`409`) when the client hash differs from the
+  server hash
+
+Suggested entry point:
+
+```ts
+export async function assertSchemaHashMatches(input: {
+  request: Request;
+  scope: ContentScope;
+  getSchemaSyncState: ContentSchemaSyncLookup;
+}): Promise<void> {
+  // parse header, load sync state, throw RuntimeError when needed
+}
+```
+
+**Step 4: Wire the gate into create and update routes**
+
+Update `apps/server/src/lib/content-api/routes.ts` so `POST /api/v1/content`
+and `PUT /api/v1/content/:documentId` call `assertSchemaHashMatches(...)`
+before store writes. Do not add the gate to delete, restore, publish, or
+unpublish routes.
+
+**Step 5: Wire the real lookup into the runtime**
+
+Update `apps/server/src/lib/runtime-with-modules.ts` so
+`mountContentApiRoutes()` receives a `getSchemaSyncState` callback that reads
+the target `(project, environment)` row from `schemaSyncs`.
+
+For tests that mount routes directly, provide a lightweight stub callback.
+
+**Step 6: Run the targeted schema-gate tests**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/content-api.test.ts --test-name-pattern "schema hash|SCHEMA_HASH|not synced"
+```
+
+Expected: PASS for the new schema-gate cases.
+
+**Step 7: Commit**
+
+```bash
+git add apps/server/src/lib/content-api/schema-hash.ts apps/server/src/lib/content-api/types.ts apps/server/src/lib/content-api/parsing.ts apps/server/src/lib/content-api/routes.ts apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/content-api.test.ts
+git commit -m "feat(server): add cms-29 schema hash gate"
+```
+
+### Task 4: Add Failing Reference-Identity Coverage
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Add failing create/update tests for reference writes**
+
+Add DB-backed tests in `apps/server/src/lib/content-api.test.ts` for:
+
+- valid reference UUID strings succeed on create and update when the schema hash
+  gate passes
+- malformed UUID strings return `INVALID_INPUT`
+- non-string reference values return `INVALID_INPUT`
+- missing referenced targets return `INVALID_INPUT`
+- deleted referenced targets return `INVALID_INPUT`
+- wrong-type referenced targets return `INVALID_INPUT`
+- nested object references validate recursively
+- arrays of references validate recursively
+
+Reuse the existing CMS-26 schema fixture and extend it with at least one array
+reference field so the write helper has both nested-object and array coverage.
+
+**Step 2: Add direct-store tests for DB and in-memory parity**
+
+Add focused direct-store tests proving both `createDatabaseContentStore(...)`
+and `createInMemoryContentStore(...)` enforce the same reference validation
+when schema snapshots are present for the target type.
+
+**Step 3: Run the targeted tests to verify they fail**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/content-api.test.ts --test-name-pattern "reference identity|reference write|cms-28"
+```
+
+Expected: FAIL because writes currently accept arbitrary JSON values in
+`frontmatter`.
+
+**Step 4: Commit the failing tests**
+
+```bash
+git add apps/server/src/lib/content-api.test.ts
+git commit -m "test: codify cms-28 reference identity"
+```
+
+### Task 5: Implement Reusable Reference Validation
+
+**Files:**
+
+- Create: `apps/server/src/lib/content-api/reference-validation.ts`
+- Modify: `apps/server/src/lib/content-api/database-store.ts`
+- Modify: `apps/server/src/lib/content-api/in-memory-store.ts`
+- Modify: `apps/server/src/lib/content-api/parsing.ts`
+- Modify: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Create a reusable reference-validation helper**
+
+Create `apps/server/src/lib/content-api/reference-validation.ts` with pure
+schema walkers that:
+
+- traverse nested objects and arrays
+- detect reference-bearing fields from `SchemaRegistryTypeSnapshot`
+- validate that each stored value is a UUID string
+- return full frontmatter paths such as `frontmatter.author` or
+  `frontmatter.reviewers[0]`
+
+Suggested shape:
+
+```ts
+export type ReferenceValidationFailure = {
+  fieldPath: string;
+  reason:
+    | "invalid_shape"
+    | "invalid_uuid"
+    | "not_found"
+    | "deleted"
+    | "type_mismatch";
+  targetType: string;
+  documentId?: string;
+};
+```
+
+**Step 2: Integrate the helper into the database store**
+
+Update `apps/server/src/lib/content-api/database-store.ts` so create/update:
+
+- load the effective type schema for the routed environment
+- reject unknown types with `INVALID_INPUT`
+- validate reference fields before insert/update
+- resolve targets only within the same routed `(project, environment)`
+- reject deleted or wrong-type targets with `INVALID_INPUT`
+
+Keep non-reference field behavior unchanged.
+
+**Step 3: Integrate the helper into the in-memory store**
+
+Update `apps/server/src/lib/content-api/in-memory-store.ts` so the in-memory
+store enforces the same reference rules when schema snapshots are present.
+
+This keeps route tests and direct store tests aligned.
+
+**Step 4: Run the targeted reference tests**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/content-api.test.ts --test-name-pattern "reference identity|reference write|cms-28"
+```
+
+Expected: PASS for the new reference-write cases.
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/content-api/reference-validation.ts apps/server/src/lib/content-api/database-store.ts apps/server/src/lib/content-api/in-memory-store.ts apps/server/src/lib/content-api/parsing.ts apps/server/src/lib/content-api.test.ts
+git commit -m "feat(server): enforce cms-28 reference identity"
+```
+
+### Task 6: Run Full Verification And Cleanup
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api.test.ts`
+- Modify: `apps/server/src/lib/content-api/routes.ts`
+- Modify: `apps/server/src/lib/content-api/database-store.ts`

+- Modify: `docs/specs/SPEC-004-schema-system-and-sync.md`
+- Modify: `apps/server/README.md`
+
+**Step 1: Run the focused server suite**
+
+Run:
+
+```bash
+bun test apps/server/src/lib/content-api.test.ts
+```
+
+Expected: PASS for existing content API coverage plus the new CMS-28/CMS-29
+cases.
+
+**Step 2: Run workspace format check**
+
+Run:
+
+```bash
+bun run format:check
+```
+
+Expected: PASS.
+
+**Step 3: Run the workspace baseline check**
+
+Run:
+
+```bash
+bun run check
+```
+
+Expected: PASS.
+
+**Step 4: Confirm git hygiene**
+
+Run:
+
+```bash
+git status --short
+```
+
+Expected:
+
+- only task-related tracked files are staged or modified
+- local-only paths such as `docs/plans/`, `ROADMAP_TASKS.md`, `AGENTS.md`, and
+  `.codex/` remain unstaged and uncommitted
+
+**Step 5: Final commit**
+
+```bash
+git add docs/specs/SPEC-003-content-storage-versioning-and-migrations.md docs/specs/SPEC-004-schema-system-and-sync.md apps/server/README.md apps/server/src/lib/content-api/schema-hash.ts apps/server/src/lib/content-api/reference-validation.ts apps/server/src/lib/content-api/types.ts apps/server/src/lib/content-api/parsing.ts apps/server/src/lib/content-api/routes.ts apps/server/src/lib/content-api/database-store.ts apps/server/src/lib/content-api/in-memory-store.ts apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/content-api.test.ts

+# CMS-32 Content Integration Design
+
+Date: 2026-03-18
+Task: CMS-32
+
+## Goal
+
+Turn the existing DB-backed content route coverage into a deterministic, CI-gated integration suite for lifecycle, routing, uniqueness, restore, schema-hash, and resolve behaviors.
+
+## Canonical Inputs
+
+- `ROADMAP_TASKS.md` CMS-32
+- `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
+- `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
+- `docs/specs/SPEC-009-i18n-and-environments.md`
+
+## Spec Delta
+
+No spec delta is required. CMS-32 only strengthens verification and CI gating for already-specified behavior.
+
+## Scope
+
+### In Scope
+
+- Extract DB-backed content route scenarios into a dedicated integration suite.
+- Keep in-memory content route tests for fast contract and smoke coverage.
+- Factor shared content test harness code into reusable support helpers.
+- Add a deterministic integration runner that boots Docker Compose, waits for services, runs the DB-backed suite, and tears the stack down.
+- Wire the new integration suite into the existing root `integration` command and CI job.
+- Document the new local operator workflow in the server README.
+
+### Out of Scope
+
+- Replacing the content store abstraction.
+- Removing `createInMemoryContentStore`.
+- Reworking the entire CI workflow structure.
+- Redesigning Docker Compose services beyond what is required to run the new suite.
+
+## Design Decisions
+
+### 1. Keep the In-Memory Store
+
+`createInMemoryContentStore` remains in the codebase.
+
+Its responsibility becomes:
+
+- fast route-level contract checks
+- parsing and validation coverage
+- envelope and pagination formatting checks
+- basic route/store smoke coverage
+
+It is no longer the evidence for production persistence semantics.
+
+### 2. Create a Dedicated DB-Backed Content Integration Suite
+
+Introduce a new integration-focused test file:
+
+- `apps/server/src/lib/content-api.integration.test.ts`
+
+This suite becomes the canonical regression gate for:
+
+- draft/publish/unpublish lifecycle
+- published-default vs `draft=true` reads
+- deleted visibility behavior
+- version history and immutable snapshots
+- restore flows and restore conflict handling
+- routing isolation across project/environment scope
+- DB uniqueness and conflict mapping
+- schema-hash enforcement on real write paths
+- DB-backed `resolve` behavior and its failure cases
+
+### 3. Extract Shared Test Support
+
+Move reusable DB test harness code into:
+
+- `apps/server/src/lib/content-api-test-support.ts`
+
+Expected shared helpers:
+
+- DB connectivity probe
+- authenticated test context creation
+- schema registry seeding
+- common scope headers
+- common request helpers
+- deterministic fixture/namespace helpers
+
+### 4. Make Fixtures Deterministic by Label
+
+Avoid `Date.now()` / `Math.random()` as the primary fixture naming mechanism inside the extracted integration suite.
+
+Each test should derive stable labels for:
+
+- project name
+- path segments
+- auth email
+- schema source ids
+
+This keeps the suite easier to debug and more repeatable against a fresh DB in CI.
+
+### 5. Add a Dedicated Integration Runner
+
+Introduce a root script:
+
+- `scripts/content-api-integration-check.sh`
+
+Responsibilities:
+
+1. Start Docker Compose with build.
+2. Wait for `postgres`, `db-migrate`, and `server` readiness.
+3. Run the dedicated server integration test command from the host workspace.
+4. Tear down the Compose stack and volumes on exit.
+
+Existing scripts remain:
+
+- `scripts/compose-health-check.sh`
+- `scripts/migration-startup-check.sh`
+
+### 6. Strengthen the Existing Integration Gate
+
+Update root `package.json` so `bun run integration` covers:
+
+1. compose health
+2. migration startup/schema validation
+3. content API DB integration suite
+
+The GitHub Actions integration job can continue calling `bun run integration`.
+
+## Test Ownership Split
+
+### Fast Route Suite
+
+`apps/server/src/lib/content-api.test.ts`
+
+Keeps:
+
+- in-memory route smoke coverage
+- parsing/query validation
+- response envelope assertions
+- routing-guard smoke behavior
+- any storage-independent checks that should stay fast
+
+### DB Integration Suite
+
+`apps/server/src/lib/content-api.integration.test.ts`
+
+Owns:
+
+- lifecycle and visibility
+- restore paths
+- routing isolation
+- uniqueness/conflict behavior
+- schema-hash transport and persistence behavior
+- DB-backed `resolve`
+- DB race/constraint precedence mapping
+
+## Verification
+
+Task completion should be backed by:
+
+- `bun run format:check`
+- `bun run check`
+- `bun run integration`
+
+## Notes
+
+- `docs/plans/` is local-only in this repository, so this design doc should remain untracked.
+- No public API contract changes are introduced; README documentation only needs to describe the new local integration workflow.

+# CMS-32 Content Integration Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Extract a dedicated DB-backed content integration suite, keep fast in-memory route tests, and wire the new suite into the root integration gate and CI path for CMS-32.
+
+**Architecture:** Split content API test ownership into a fast route-contract suite and a canonical DB-backed integration suite. Reuse a shared support module for test harness concerns, then run the DB suite through a dedicated Compose-backed shell script that becomes part of the root `integration` command.
+
+**Tech Stack:** Bun, Nx workspace scripts, Node test runner via `bun test`, Docker Compose, Postgres, Elysia route handler tests, Drizzle-backed content store
+
+---
+
+### Task 1: Inventory and Carve Out Shared Test Support
+
+**Files:**
+
+- Create: `apps/server/src/lib/content-api-test-support.ts`
+- Modify: `apps/server/src/lib/content-api.test.ts`
+- Test: `apps/server/src/lib/content-api.test.ts`
+
+**Step 1: Write the failing test or import boundary**
+
+Move no DB-backed assertions yet. First add a support module export surface for existing helpers used by both suites:
+
+- `dbEnv`
+- `logger`
+- `scopeHeaders`
+- `createDatabaseTestContext(...)`
+- `seedSchemaRegistryScope(...)`
+- request helper utilities needed by extracted tests
+
+Expected first failure: `content-api.test.ts` cannot compile until imports are updated.
+
+**Step 2: Run test/typecheck to verify the extraction breaks before fix**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts`
+Expected: FAIL or compile error from moved helpers/imports.
+
+**Step 3: Write minimal implementation**
+
+Create `apps/server/src/lib/content-api-test-support.ts` by moving shared DB harness code out of `content-api.test.ts`. Keep helper signatures unchanged where possible to minimize churn.
+
+**Step 4: Run tests to verify the extraction passes**
+
+Run: `bun test apps/server/src/lib/content-api.test.ts`
+Expected: PASS for the remaining suite or only DB-skipped tests remain skipped.
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/content-api-test-support.ts apps/server/src/lib/content-api.test.ts
+git commit -m "test(server): extract content api test support"
+```
+
+### Task 2: Create the Dedicated DB-Backed Integration Suite Skeleton
+
+**Files:**
+
+- Create: `apps/server/src/lib/content-api.integration.test.ts`
+- Modify: `apps/server/src/lib/content-api.test.ts`
+- Test: `apps/server/src/lib/content-api.integration.test.ts`
+
+**Step 1: Write the failing integration suite skeleton**
+
+Create a new integration file that imports the shared support helpers and defines at least one existing DB-backed test copied from `content-api.test.ts`.
+
+Expected first failure: the new file is not yet covered by a dedicated script and may expose missing imports/helpers.
+
+**Step 2: Run the new test file directly**
+
+Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
+Expected: FAIL from missing imports, missing helper exports, or copied code that still references old local helpers.
+
+**Step 3: Write minimal implementation**
+
+Fix imports and shared helper usage so the integration file runs. Keep `testWithDatabase` behavior for now if needed, but make the file structurally independent from `content-api.test.ts`.
+
+**Step 4: Re-run the new test file**
+
+Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
+Expected: PASS locally when Postgres is available; otherwise DB tests skip cleanly.
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/content-api.integration.test.ts apps/server/src/lib/content-api.test.ts
+git commit -m "test(server): add content api integration suite skeleton"
+```
+
+### Task 3: Move Canonical DB Lifecycle, Restore, and Routing Coverage
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api.integration.test.ts`
+- Modify: `apps/server/src/lib/content-api.test.ts`
+- Test: `apps/server/src/lib/content-api.integration.test.ts`
+
+**Step 1: Move the failing DB-backed scenarios**
+
+Move DB-backed tests for:
+
+- lifecycle and visibility
+- restore flows
+- routed project isolation
+
+Delete the moved DB-backed copies from `content-api.test.ts`.
+
+Expected first failure: copied tests still depend on old file-local state or helper functions.
+
+**Step 2: Run only the new integration file**
+
+Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
+Expected: FAIL on missing helper references or broken setup assumptions after the move.
+
+**Step 3: Write minimal implementation**
+
+Repair imports, helpers, and setup so moved tests run unchanged in behavior.
+
+**Step 4: Run the integration file again**
+
+Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
+Expected: PASS with DB available.
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/content-api.integration.test.ts apps/server/src/lib/content-api.test.ts
+git commit -m "test(server): move lifecycle restore and routing integration coverage"
+```
+
+### Task 4: Move DB Uniqueness, Conflict Mapping, Schema-Hash, and Resolve Coverage
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api.integration.test.ts`
+- Modify: `apps/server/src/lib/content-api.test.ts`
+- Test: `apps/server/src/lib/content-api.integration.test.ts`
+
+**Step 1: Move the remaining DB-backed regression groups**
+
+Move DB-backed tests for:
+
+- path conflict and translation variant conflict
+- soft-deleted or cross-scope source handling
+- race/constraint precedence checks
+- schema-hash required/mismatch/not-synced/match cases
+- DB-backed `resolve` scenarios
+
+Expected first failure: copied tests expose helper duplication or ordering assumptions.
+
+**Step 2: Run the integration file**
+
+Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
+Expected: FAIL until moved imports and local helpers are normalized.
+
+**Step 3: Write minimal implementation**
+
+Normalize helper usage and trim `content-api.test.ts` down to fast route tests plus any intentionally retained storage-independent checks.
+
+**Step 4: Re-run the integration file**
+
+Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
+Expected: PASS with DB available.
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/content-api.integration.test.ts apps/server/src/lib/content-api.test.ts
+git commit -m "test(server): move db content regressions into integration suite"
+```
+
+### Task 5: Add Deterministic Fixture Labels in the Integration Suite
+
+**Files:**
+
+- Modify: `apps/server/src/lib/content-api-test-support.ts`
+- Modify: `apps/server/src/lib/content-api.integration.test.ts`
+- Test: `apps/server/src/lib/content-api.integration.test.ts`
+
+**Step 1: Write a failing deterministic helper expectation**
+
+Introduce helper usage so tests stop directly assembling names with `Date.now()` / `Math.random()` in moved CMS-32 scenarios.
+
+Expected first failure: compile errors until helper functions exist.
+
+**Step 2: Run the integration suite**
+
+Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
+Expected: FAIL on missing helper implementations.
+
+**Step 3: Write minimal implementation**
+
+Add small deterministic namespace helpers, for example:
+
+- `createTestNamespace(testId)`
+- `scopedPath(testId, suffix)`
+- `scopedEmail(testId)`
+
+Use a simple monotonic or label-driven strategy that is deterministic within the suite and unique per test case.
+
+**Step 4: Re-run the integration suite**
+
+Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
+Expected: PASS with cleaner, label-driven fixtures.
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/content-api-test-support.ts apps/server/src/lib/content-api.integration.test.ts
+git commit -m "test(server): make content integration fixtures deterministic"
+```
+
+### Task 6: Add a Dedicated Server Integration Command
+
+**Files:**
+
+- Modify: `apps/server/package.json`
+- Test: `apps/server/package.json`
+
+**Step 1: Write the failing command path**
+
+Add a new script entry such as:
+
+- `test:integration:content`
+
+that points at `src/lib/content-api.integration.test.ts`.
+
+Expected first failure: the script may not exist yet when invoked.
+
+**Step 2: Run the new script**
+
+Run: `bun run --cwd apps/server test:integration:content`
+Expected: FAIL before the script is added.
+
+**Step 3: Write minimal implementation**
+
+Add the script in `apps/server/package.json` using the same Bun test conventions already used in the package.
+
+**Step 4: Re-run the command**
+
+Run: `bun run --cwd apps/server test:integration:content`
+Expected: PASS with DB available, or clean skips when DB is unavailable outside Compose.
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/package.json
+git commit -m "chore(server): add content integration test command"
+```
+
+### Task 7: Add the Compose-Backed Integration Check Script
+
+**Files:**
+
+- Create: `scripts/content-api-integration-check.sh`
+- Test: `scripts/content-api-integration-check.sh`
+
+**Step 1: Write the failing shell script skeleton**
+
+Create a script that:
+
+1. starts Docker Compose
+2. waits for `postgres`
+3. waits for `db-migrate`
+4. waits for `server`
+5. runs `bun run --cwd apps/server test:integration:content`
+6. tears down the stack with volumes on exit
+
+Expected first failure: shell syntax mistakes or missing readiness helpers.
+
+**Step 2: Run the script**
+
+Run: `bash scripts/content-api-integration-check.sh`
+Expected: FAIL the first time until readiness and cleanup logic is correct.
+
+**Step 3: Write minimal implementation**
+
+Model the script after the existing Compose health and migration scripts. Reuse the same waiting and cleanup patterns rather than inventing new shell behavior.
+
+**Step 4: Re-run the script**
+
+Run: `bash scripts/content-api-integration-check.sh`
+Expected: PASS and execute the DB-backed suite against a fresh Compose stack.
+
+**Step 5: Commit**
+
+```bash
+git add scripts/content-api-integration-check.sh
+git commit -m "test(ci): add content api integration check"
+```
+
+### Task 8: Wire the New Check into the Root Integration Gate
+
+**Files:**
+
+- Modify: `package.json`
+- Test: `package.json`
+
+**Step 1: Make the integration command fail until the new script is included**
+
+Update the root `integration` script to append `bash scripts/content-api-integration-check.sh`.
+
+Expected first failure: `bun run integration` now fails until the new script is correct.
+
+**Step 2: Run the root integration command**
+
+Run: `bun run integration`
+Expected: FAIL if any of the three checks still break under the new chain.
+
+**Step 3: Write minimal implementation**
+
+Adjust the script ordering or shell command if needed so the root integration flow is:
+
+1. compose health
+2. migration startup check
+3. content API integration check
+
+**Step 4: Re-run the root integration command**
+
+Run: `bun run integration`
+Expected: PASS.
+
+**Step 5: Commit**
+
+```bash
+git add package.json
+git commit -m "ci: gate integration on content api db suite"
+```
+
+### Task 9: Document the Local Operator Workflow
+
+**Files:**
+
+- Modify: `apps/server/README.md`
+- Test: `apps/server/README.md`
+
+**Step 1: Add the missing docs block**
+
+Document:
+
+- the fast suite command
+- the dedicated DB-backed content integration command
+- the root integration command that exercises the Compose-backed gate
+
+Expected first failure: no code failure; this is documentation completion tied to roadmap acceptance.
+
+**Step 2: Verify docs reflect real commands**
+
+Run:
+
+- `bun run --cwd apps/server test`
+- `bun run --cwd apps/server test:integration:content`
+- `bun run integration`
+
+Expected: all commands exist and docs text matches them exactly.
+
+**Step 3: Write minimal implementation**
+
+Add a concise README section under server testing or content API documentation.
+
+**Step 4: Re-check formatting**
+
+Run: `bun x prettier --check apps/server/README.md`
+Expected: PASS.
+
+**Step 5: Commit**
+
+```bash

+# CMS-40 OIDC Provider Support Design
+
+Date: 2026-03-18
+Task: CMS-40
+
+## Goal
+
+Specify a concrete, minimal OIDC integration contract for MDCMS that uses the Better Auth SSO plugin with startup-configured providers, canonical claims mapping, and a deterministic fixture matrix.
+
+## Canonical Inputs
+
+- `ROADMAP_TASKS.md` CMS-40
+- `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
+- `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
+- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+- `docs/adrs/ADR-001-backend-framework-bun-elysia.md`
+
+## Spec Delta
+
+`SPEC-005` needs a normative OIDC section that:
+
+- makes the Better Auth SSO plugin the MDCMS OIDC mechanism
+- fixes CMS-40 to startup-configured provider profiles only
+- defines the supported provider set for this task
+- defines canonical claims mapping and deny-by-default error categories
+- adds the OIDC sign-in and callback routes to the auth endpoint family
+
+## Scope
+
+### In Scope
+
+- OIDC via Better Auth SSO plugin
+- Static startup provider configuration
+- Supported provider profile set:
+  - `okta`
+  - `azure-ad`
+  - `google-workspace`
+  - `auth0`
+- Canonical claims normalization for MDCMS users/sessions
+- Deterministic failure categories for config, sign-in initiation, callback, and missing required claims
+- Fixture-matrix expectations for the four provider profiles
+
+### Out of Scope
+
+- Runtime provider registration
+- Studio provider settings UI
+- SAML behavior beyond preserving the CMS-41 handoff
+- Arbitrary provider IDs outside the four CMS-40 profiles
+- Provider-specific operator workflows beyond startup config and restart
+
+## Design Decisions
+
+### 1. Standardize on Better Auth SSO Plugin
+
+MDCMS should explicitly standardize on the Better Auth SSO plugin for OIDC.
+
+This keeps MDCMS responsible for:
+
+- allowed provider profiles
+- startup config contract
+- canonical claim mapping
+- deterministic operator and test guarantees
+
+It leaves the protocol mechanics, callback handling, and discovery logic to Better Auth.
+
+### 2. Use Startup Configuration Only
+
+Provider definitions should be static server startup config for CMS-40.
+
+This avoids:
+
+- new admin APIs
+- secret management UI
+- provider CRUD persistence
+- runtime validation and rollback workflows
+
+Changes to provider configuration should require server restart.
+
+### 3. Keep the Provider Set Closed
+
+CMS-40 should make the supported provider set explicit and finite:
+
+- `okta`
+- `azure-ad`
+- `google-workspace`
+- `auth0`
+
+The fixture matrix then proves support for a known set rather than a vague "OIDC-compatible" promise.
+
+### 4. Fix the Canonical Claims Mapping
+
+The provider-specific OIDC profile shape should normalize to a single MDCMS user/session shape:
+
+- `id <- sub`
+- `email <- email`
+- `emailVerified <- email_verified` or `false` when missing
+- `name <- name`, then `given_name + family_name`, then `preferred_username`, then `email`
+- `image <- picture` or `null`
+
+Missing `sub` or usable `email` should fail sign-in deterministically.
+
+### 5. Restrict the MDCMS OIDC Surface
+
+CMS-40 should define MDCMS-supported usage of the Better Auth SSO plugin as:
+
+- initiate login with `providerId`
+- callback handled under `/api/v1/auth/sso/callback/:providerId`
+- relative or same-origin callback URLs only
+
+CMS-40 should not promise:
+
+- email/domain-based provider discovery
+- runtime provider registration
+- organization provisioning
+- shared redirect URI behavior
+
+## Verification
+
+Task completion should be backed by:
+
+- provider-fixture integration coverage for all four provider profiles
+- successful claims normalization assertions across the fixture matrix
+- negative coverage for missing claims and unconfigured provider IDs
+- `bun run format:check`
+- `bun run check`
+
+## Notes
+
+- `docs/plans/` is local-only in this repository, so this design doc should remain untracked.
+- This design intentionally prefers a closed provider matrix over a generic "any OIDC provider" promise so CMS-40 stays testable and bounded.

+# CMS-40 OIDC Provider Support Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add startup-configured OIDC provider support to MDCMS using the Better Auth SSO plugin, canonical claims mapping, and a deterministic provider fixture matrix.
+
+**Architecture:** MDCMS keeps Better Auth SSO as the protocol and callback engine while owning a typed startup config contract, provider allowlist, claims normalization, and fixture-backed regression coverage. The implementation should validate provider config at startup, reject unsupported provider IDs by default, and keep the CMS-40 scope limited to static instance configuration.
+
+**Tech Stack:** Bun, Nx, TypeScript, Elysia, Better Auth, `@better-auth/sso`, Drizzle, Node test runner
+
+---
+
+### Task 1: Lock the spec and operator contract
+
+**Files:**
+
+- Modify: `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
+- Modify: `apps/server/README.md`
+- Test: none
+
+**Step 1: Re-read the approved CMS-40 design and current auth spec**
+
+Run: `sed -n '1,260p' docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
+Expected: current auth section and endpoint table with no OIDC startup-config contract beyond generic SSO mention
+
+**Step 2: Update the auth spec with the CMS-40 OIDC delta**
+
+Add the normative sections for:
+
+- Better Auth SSO plugin as the MDCMS OIDC mechanism
+- startup-only provider configuration
+- supported provider IDs: `okta`, `azure-ad`, `google-workspace`, `auth0`
+- canonical claims mapping
+- OIDC sign-in and callback endpoint contracts
+- deterministic failure categories
+
+**Step 3: Update the server README with the operator workflow**
+
+Document:
+
+- the `MDCMS_AUTH_OIDC_PROVIDERS` startup env contract
+- restart requirement after config changes
+- supported provider IDs
+- callback URL restrictions
+
+**Step 4: Run formatting checks for the touched docs**
+
+Run: `bun run format:check`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add docs/specs/SPEC-005-auth-authorization-and-request-routing.md apps/server/README.md
+git commit -m "docs(auth): specify CMS-40 oidc provider contract"
+```
+
+### Task 2: Add typed OIDC startup config parsing
+
+**Files:**
+
+- Modify: `apps/server/src/lib/env.ts`
+- Modify: `packages/shared/src/lib/runtime/env.ts` (only if shared parsing helpers are needed)
+- Modify: `.env.example`
+- Test: `packages/shared/src/lib/runtime/env.test.ts` or `apps/server/src/lib/*.test.ts`
+
+**Step 1: Write the failing env parsing test**
+
+Add focused tests covering:
+
+- valid `MDCMS_AUTH_OIDC_PROVIDERS` JSON
+- invalid JSON
+- unsupported `providerId`
+- duplicate provider IDs
+- missing required fields
+
+**Step 2: Run the targeted test to verify red**
+
+Run: `bun test packages/shared/src/lib/runtime/env.test.ts`
+Expected: FAIL on missing OIDC parsing behavior
+
+**Step 3: Implement minimal OIDC env parsing**
+
+Add a typed parser for:
+
+- `MDCMS_AUTH_OIDC_PROVIDERS`
+- provider shape: `providerId`, `issuer`, `domain`, `clientId`, `clientSecret`
+- optional `scopes`
+- optional `trustedOrigins`
+- optional discovery overrides for endpoint and token auth method fixes
+
+Reject malformed or unsupported provider entries with `INVALID_ENV`.
+
+**Step 4: Re-run the targeted test**
+
+Run: `bun test packages/shared/src/lib/runtime/env.test.ts`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/env.ts packages/shared/src/lib/runtime/env.ts packages/shared/src/lib/runtime/env.test.ts .env.example
+git commit -m "feat(server): parse startup oidc provider config"
+```
+
+### Task 3: Wire Better Auth SSO into the server auth service
+
+**Files:**
+
+- Modify: `apps/server/package.json`
+- Modify: `apps/server/src/lib/auth.ts`
+- Test: `apps/server/src/lib/auth.test.ts`
+
+**Step 1: Write the failing auth-service tests**
+
+Add tests that prove:
+
+- configured provider profiles are registered at startup
+- unsupported provider IDs are rejected
+- callback URL validation is same-origin or relative-path only
+- missing required claims fail deterministically
+
+**Step 2: Run the targeted auth test**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+Expected: FAIL on missing SSO/OIDC behavior
+
+**Step 3: Add the minimal Better Auth SSO wiring**
+
+Implement:
+
+- `@better-auth/sso` dependency
+- plugin registration in `createAuthService(...)`
+- startup provider registration from parsed env config
+- canonical claims mapping
+- deny-by-default provider allowlist
+- callback URL validation
+
+Do not add runtime registration APIs or Studio settings UI.
+
+**Step 4: Re-run the targeted auth test**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+Expected: PASS for the new OIDC cases and existing auth coverage
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/package.json bun.lock apps/server/src/lib/auth.ts apps/server/src/lib/auth.test.ts
+git commit -m "feat(server): add static oidc provider support"
+```
+
+### Task 4: Build the provider fixture matrix
+
+**Files:**
+
+- Create: `apps/server/src/lib/auth-oidc-fixtures.ts` or a similarly named test helper
+- Modify: `apps/server/src/lib/auth.test.ts`
+- Test: `apps/server/src/lib/auth.test.ts`
+
+**Step 1: Write the failing fixture-driven tests**
+
+Add one test per supported provider profile:
+
+- `okta`
+- `azure-ad`
+- `google-workspace`
+- `auth0`
+
+Each fixture should prove:
+
+- startup config is accepted
+- sign-in route targets the expected provider
+- canonical claims mapping yields the same MDCMS user fields
+
+Add negative fixtures for:
+
+- missing `email`
+- missing `sub`
+- unconfigured provider ID
+
+**Step 2: Run the fixture tests to verify red**
+
+Run: `bun test apps/server/src/lib/auth.test.ts --test-name-pattern="oidc|sso"`
+Expected: FAIL until fixture helpers and mappings exist
+
+**Step 3: Implement the minimal fixture helpers**
+
+Use deterministic local fixtures, not live SaaS tenants.
+
+The fixture helpers should:
+
+- create provider config inputs
+- create normalized user-info payloads per provider profile
+- assert the same MDCMS user/session output
+
+**Step 4: Re-run the fixture tests**
+
+Run: `bun test apps/server/src/lib/auth.test.ts --test-name-pattern="oidc|sso"`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/auth.test.ts apps/server/src/lib/auth-oidc-fixtures.ts
+git commit -m "test(server): add oidc provider fixture matrix"
+```
+
+### Task 5: Verify the full CMS-40 slice
+
+**Files:**
+
+- Modify: none unless fixes are required
+- Test: existing touched tests
+
+**Step 1: Run formatting**
+
+Run: `bun run format:check`
+Expected: PASS
+
+**Step 2: Run workspace checks**
+
+Run: `bun run check`
+Expected: PASS
+
+**Step 3: Run the targeted auth suite**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+Expected: PASS
+
+**Step 4: Inspect git status**
+
+Run: `git status --short`
+Expected: only task-scoped tracked changes; local-only files such as `docs/plans/` remain unstaged
+
+**Step 5: Final commit if any verification fixes were needed**
+
+```bash
+git add <task-scoped-files>
+git commit -m "test(server): finalize cms-40 verification"
+```

+# CMS-41 SAML Provider Support Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add startup-configured SAML 2.0 provider support to MDCMS using the existing Better Auth SSO plugin, provider-presence enablement, and deterministic ACS/metadata regression coverage.
+
+**Architecture:** Extend the current OIDC-only startup auth pipeline into a mixed static SSO registry. Keep OIDC and SAML operator config separate in env parsing, normalize both into Better Auth `defaultSSO` providers at startup, and add SAML-specific ACS plus SP metadata coverage without introducing runtime provider management or IdP-initiated flows.
+
+**Tech Stack:** Bun, Nx, TypeScript, Elysia, Better Auth, `@better-auth/sso`, Drizzle, `samlify`, Node test runner
+
+---
+
+## Spec Delta
+
+- `docs/specs/SPEC-005-auth-authorization-and-request-routing.md` now defines startup-configured `MDCMS_AUTH_SAML_PROVIDERS`, provider-presence enablement, canonical SAML attribute mapping, and the `/api/v1/auth/sso/saml2/sp/acs/:providerId` and `/api/v1/auth/sso/saml2/sp/metadata` endpoints.
+- The affected behavior is in the server auth boundary only: startup env parsing, Better Auth SSO provider registration, shared `POST /api/v1/auth/sign-in/sso`, SAML ACS handling, and SP metadata exposure.
+- Acceptance criteria that depend on this delta:
+  - “disabled by default” now means no SAML providers are available when `MDCMS_AUTH_SAML_PROVIDERS` is absent or empty
+  - “enabled instances pass login flows” now means configured SAML providers complete SP-initiated sign-in and establish the normal MDCMS session
+  - deterministic failures must map to `INVALID_ENV`, `SSO_PROVIDER_NOT_CONFIGURED`, `AUTH_SAML_REQUIRED_ATTRIBUTE_MISSING`, and `AUTH_PROVIDER_ERROR`
+
+## Conflict Note
+
+- `ROADMAP_TASKS.md` still says `SAML beta-flag integration path`, but the owning spec has removed `beta` and the extra enablement flag.
+- Execute against the stricter spec-owned contract, not the stale roadmap wording.
+
+## Workspace Note
+
+- The current worktree already has unrelated unstaged changes in `packages/shared/`.
+- Implement this plan in a fresh worktree or with strict staged-file discipline so CMS-41 stays isolated.
+
+### Task 1: Add typed SAML startup config parsing
+
+**Files:**
+
+- Modify: `apps/server/src/lib/env.ts`
+- Modify: `apps/server/src/lib/env.test.ts`
+- Modify: `.env.example`
+
+**Step 1: Write the failing env parsing tests**
+
+Add focused tests for:
+
+- valid `MDCMS_AUTH_SAML_PROVIDERS` parsing
+- absent or blank `MDCMS_AUTH_SAML_PROVIDERS` returning `[]`
+- malformed JSON
+- non-array payload
+- missing required SAML fields (`providerId`, `issuer`, `domain`, `entryPoint`, `cert`)
+- duplicate SAML domains
+- duplicate `providerId` across OIDC and SAML provider sets
+
+**Step 2: Run the targeted env test to verify red**
+
+Run: `bun test apps/server/src/lib/env.test.ts`
+Expected: FAIL on missing SAML parsing/types or missing cross-protocol uniqueness checks
+
+**Step 3: Implement minimal SAML env parsing**
+
+Add a typed parser for:
+
+- `MDCMS_AUTH_SAML_PROVIDERS`
+- required fields: `providerId`, `issuer`, `domain`, `entryPoint`, `cert`
+- optional fields: `audience`, `spEntityId`, `identifierFormat`, `authnRequestsSigned`, `wantAssertionsSigned`, `attributeMapping`
+
+Implementation details:
+
+- extend `ServerEnv` with `MDCMS_AUTH_SAML_PROVIDERS`
+- preserve the current OIDC parser unchanged except for shared cross-protocol `providerId` uniqueness
+- keep missing or blank `MDCMS_AUTH_SAML_PROVIDERS` equivalent to “no configured SAML providers”
+- keep errors as deterministic `INVALID_ENV` envelopes keyed to the offending env var
+
+**Step 4: Update the operator env example**
+
+Add a commented `MDCMS_AUTH_SAML_PROVIDERS` example to `.env.example` alongside the existing OIDC example and note that providers are enabled by presence, not by a separate flag.
+
+**Step 5: Re-run the targeted env test**
+
+Run: `bun test apps/server/src/lib/env.test.ts`
+Expected: PASS
+
+**Step 6: Commit**
+
+```bash
+git add apps/server/src/lib/env.ts apps/server/src/lib/env.test.ts .env.example
+git commit -m "feat(server): parse startup saml provider config"
+```
+
+### Task 2: Extend the auth service to register static SAML providers
+
+**Files:**
+
+- Modify: `apps/server/src/lib/auth.ts`
+- Modify: `apps/server/src/lib/auth.test.ts`
+
+**Step 1: Write the failing auth-service tests**
+
+Add unit-level tests proving:
+
+- the shared SSO sign-in payload accepts a configured SAML `providerId`
+- `SSO_PROVIDER_NOT_CONFIGURED` is protocol-neutral, not OIDC-only
+- static SAML provider config is converted into Better Auth SSO provider input
+- the Better Auth plugin options enable the required SAML protections:
+  - `enableInResponseToValidation: true`
+  - `allowIdpInitiated: false`
+  - `requireTimestamps: true`
+
+**Step 2: Run the targeted auth test to verify red**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+Expected: FAIL on missing SAML provider building or OIDC-specific error/messages
+
+**Step 3: Implement the minimal mixed-protocol provider registry**
+
+Implement in `apps/server/src/lib/auth.ts`:
+
+- a `SamlProviderConfig` runtime mapping compatible with `@better-auth/sso`
+- a builder that converts parsed SAML env config into Better Auth `defaultSSO` entries
+- a combined configured-provider allowlist across OIDC and SAML
+- protocol-neutral `SSO_PROVIDER_NOT_CONFIGURED` and `AUTH_PROVIDER_ERROR` messages where the code path is shared
+- shared callback URL validation for both protocols
+- Better Auth `sso(...)` registration with:
+  - all OIDC providers
+  - all SAML providers
+  - required SAML validation options from the spec
+
+Do not add:
+
+- runtime provider registration
+- Studio-managed SSO settings
+- IdP-initiated login
+- SAML Single Logout
+
+**Step 4: Re-run the targeted auth test**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+Expected: PASS for the new provider-registry assertions and existing OIDC regressions
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/auth.ts apps/server/src/lib/auth.test.ts
+git commit -m "feat(server): register static saml providers"
+```
+
+### Task 3: Add deterministic SAML fixture helpers
+
+**Files:**
+
+- Create: `apps/server/src/lib/auth-saml-fixtures.ts`
+- Modify: `apps/server/src/lib/auth.test.ts`
+
+**Step 1: Write the failing fixture-driven SAML tests**
+
+Add integration-style coverage in `apps/server/src/lib/auth.test.ts` for:
+
+- configured SAML sign-in starts from `POST /api/v1/auth/sign-in/sso`
+- SP metadata endpoint returns `200` for a configured SAML provider
+- ACS success establishes a session and redirects to `/studio`
+- missing mapped `email` or `id` becomes `AUTH_SAML_REQUIRED_ATTRIBUTE_MISSING`
+- unconfigured provider returns `SSO_PROVIDER_NOT_CONFIGURED`
+- unsolicited IdP response is rejected
+- replayed assertion is rejected
+
+**Step 2: Run the targeted auth test to verify red**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+Expected: FAIL on missing SAML test helpers and missing ACS/metadata support
+
+**Step 3: Implement the SAML fixture helper**
+
+Create `apps/server/src/lib/auth-saml-fixtures.ts` with deterministic helpers that:
+
+- define a startup-valid SAML provider config
+- generate reusable test certificates/private keys
+- decode the SP-initiated `SAMLRequest` created by the sign-in step so tests can reuse the exact request ID
+- generate signed SAML responses for:
+  - success
+  - missing email
+  - missing id
+  - replay reuse
+  - missing `InResponseTo`
+
+Prefer local deterministic XML generation over live IdP/network tests.
+
+**Step 4: Re-run the targeted auth test**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+Expected: FAIL only on missing runtime ACS/metadata behavior
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/auth-saml-fixtures.ts apps/server/src/lib/auth.test.ts
+git commit -m "test(server): add saml auth fixtures"
+```
+
+### Task 4: Add ACS and SP metadata route handling
+
+**Files:**
+
+- Modify: `apps/server/src/lib/auth.ts`
+- Modify: `apps/server/src/lib/auth.test.ts`
+
+**Step 1: Keep the SAML endpoint tests red and focused**
+
+Make sure the integration tests explicitly verify:
+
+- `GET /api/v1/auth/sso/saml2/sp/metadata?providerId=<id>&format=xml` returns metadata that references the configured ACS URL
+- `POST /api/v1/auth/sso/saml2/sp/acs/:providerId` accepts a valid signed response and issues the normal MDCMS session
+- missing mapped attributes surface `AUTH_SAML_REQUIRED_ATTRIBUTE_MISSING`
+- unsolicited or replayed responses surface deterministic failure envelopes
+
+**Step 2: Run the targeted auth test to confirm red**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+Expected: FAIL on missing route mounts or incorrect SAML error translation
+
+**Step 3: Implement the minimal route support**
+
+In `apps/server/src/lib/auth.ts`:
+
+- add route mounts for:
+  - `POST /api/v1/auth/sso/saml2/sp/acs/:providerId`
+  - `GET /api/v1/auth/sso/saml2/sp/metadata`
+- route both through `auth.handler(...)` with the same runtime error wrapping used for existing auth endpoints
+- add SAML-specific error mapping so:
+  - missing mapped identity fields become `AUTH_SAML_REQUIRED_ATTRIBUTE_MISSING`
+  - unsupported provider IDs become `SSO_PROVIDER_NOT_CONFIGURED`
+  - assertion validation/replay/issuer/signature failures become `AUTH_PROVIDER_ERROR`
+- add post-callback user normalization for the SAML ACS path similar to the existing OIDC callback normalization, but using the SAML attribute mapping defined in the provider config
+
+**Step 4: Re-run the targeted auth test**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+Expected: PASS for the new SAML route coverage and all pre-existing OIDC regressions
+
+**Step 5: Commit**
+
+```bash
+git add apps/server/src/lib/auth.ts apps/server/src/lib/auth.test.ts
+git commit -m "feat(server): add saml acs and metadata routes"
+```
+
+### Task 5: Update operator-facing auth documentation
+
+**Files:**
+
+- Modify: `apps/server/README.md`
+- Modify: `.env.example` (only if more examples are still needed after Task 1)
+
+**Step 1: Update the server README**
+
+Document:
+
+- `MDCMS_AUTH_SAML_PROVIDERS`
+- provider-presence enablement semantics
+- required and optional SAML fields
+- ACS and SP metadata routes
+- SP-initiated-only scope
+- callback URL restrictions shared with OIDC
+
+**Step 2: Run formatting checks for touched docs**
+
+Run: `bun run format:check`
+Expected: PASS
+
+**Step 3: Commit**
+
+```bash
+git add apps/server/README.md .env.example
+git commit -m "docs(server): document saml provider support"
+```
+
+### Task 6: Verify the full CMS-41 slice
+
+**Files:**
+
+- Modify: none unless verification fixes are required
+
+**Step 1: Run the env parser suite**
+
+Run: `bun test apps/server/src/lib/env.test.ts`
+Expected: PASS
+
+**Step 2: Run the auth suite**
+
+Run: `bun test apps/server/src/lib/auth.test.ts`
+Expected: PASS
+
+**Step 3: Run formatting**
+
+Run: `bun run format:check`
+Expected: PASS
+
+**Step 4: Run the workspace baseline**
+
+Run: `bun run check`
+Expected: PASS
+
+**Step 5: Inspect git status**
+
+Run: `git status --short`
+Expected:
+
+- only CMS-41 task-scoped files are staged or modified
+- unrelated local-only paths such as `.claude/`, `.codex/`, `ROADMAP_TASKS.md`, and `docs/plans/` remain unstaged
+
+**Step 6: Final verification commit if fixes were needed**
+
+```bash
+git add <cms-41-files>
+git commit -m "test(server): finalize cms-41 verification"
+```

+# Week 3 Scope and Recommended Sequencing
+
+Date: 2026-03-20
+
+Sources:
+
+- Week 3 screenshot provided in chat
+- `ROADMAP_TASKS.md`
+- `docs/specs/README.md`
+
+## Jira Status Note
+
+Live Jira status lookup was not reliable in this session. This report covers:
+
+- the visible Week 3 scope from the screenshot
+- roadmap task mapping
+- dependency-based sequencing
+
+It does **not** claim current `Done` / `To Do` counts for Week 3.
+
+## Week 3 Screenshot Transcription
+
+Visible text in the Week 3 column:
+
+- `Week 3`
+- `Platform (83d)`
+- `N - Studio Content (24d)`  
+  `CMS-56-67,75,76`
+- `O - MDX Components (21d)`  
+  `CMS-68-74`
+- `P - Studio Runtime (7.5d)`  
+  `CMS-60,61,62`
+- `T - SDK (3.5d)`  
+  `CMS-85`
+- `Q - CLI Commands (27d)`  
+  `CMS-77-87`
+
+## Important Screenshot Caveats
+
+The Week 3 screenshot is not a clean list of unique tasks.
+
+1. `P - Studio Runtime` duplicates `CMS-60,61,62`, which already sit inside the broader `CMS-56-67` range under `N - Studio Content`.
+2. `T - SDK` duplicates `CMS-85`, which already sits inside the broader `CMS-77-87` range under `Q - CLI Commands`.
+
+Because of that, the screenshot appears to mix:
+
+- broad streams (`N`, `O`, `Q`)
+- narrower callout substreams (`P`, `T`)
+
+For planning purposes, the unique Week 3 tasks visible in the screenshot are:
+
+- `CMS-56` through `CMS-87`
+
+## Roadmap Override To The Screenshot
+
+Two tasks that appear inside the screenshot ranges are explicitly re-homed by the roadmap and no longer gate MVP:
+
+- `CMS-58`
+- `CMS-86`
+
+That matters because the screenshot still visually includes them:
+
+- `CMS-58` falls inside `CMS-56-67`
+- `CMS-86` falls inside `CMS-77-87`
+
+For strict MVP sequencing, treat those two as **deferred** unless you intentionally pull them back in.
+
+## Week 3 Unique Task Set
+
+### Studio / Runtime / Content
+
+- `CMS-56` Implement publish flow + version history panel + version diff view

+
+## Key Dependency Chains Inside Week 3
+
+### Studio Runtime
+
+- `CMS-60 -> CMS-61 -> CMS-62`
+
+### Locale / Translation UI
+
+- `CMS-63 -> CMS-64`
+
+### MDX Components
+
+- `CMS-68 -> CMS-69 -> CMS-70 -> CMS-71 -> CMS-72 -> CMS-73 -> CMS-74`
+
+`CMS-74` also depends on `CMS-52`, which is outside Week 3.
+
+### CLI Core
+
+- `CMS-77 -> CMS-78`
+- `CMS-77 -> CMS-79`
+- `CMS-77 -> CMS-80 -> CMS-81 -> CMS-82 -> CMS-83`
+- `CMS-81 -> CMS-84`
+- `CMS-77 -> CMS-87`
+
+### SDK
+
+- `CMS-85` is independent of the `CMS-77` CLI chain. It depends on `CMS-17` and `CMS-21`, both outside Week 3.
+
+### Deferred
+
+- `CMS-58` depends on `CMS-52` and `CMS-54`
+- `CMS-86` depends on `CMS-82` and `CMS-53`
+
+Both are roadmap-deferred from MVP.
+
+## External Prerequisite Note
+
+Many Week 3 tasks depend on non-Week-3 tasks such as:
+
+- `CMS-48`, `CMS-49`, `CMS-50`
+- `CMS-52`
+- `CMS-17`, `CMS-18`, `CMS-19`, `CMS-20`, `CMS-24`, `CMS-42`, `CMS-44`
+
+This report does not claim those external prerequisites are complete. It only lays out the Week 3 structure and the internal dependency sequence.
+
+## Recommended Sequencing
+
+Week 3 is too broad for one useful single-file linear order. The practical approach is to run it in dependency-led tracks.
+
+### Recommended Priority Wave 1: Highest Fan-Out Foundations
+
+Start with the items that unlock the largest amount of Week 3 work:
+
+1. `CMS-60` Studio runtime loader + composition surfaces
+2. `CMS-68` component registration sync contract
+3. `CMS-77` CLI framework with profile/auth plumbing
+4. `CMS-85` SDK client
+
+Why:
+
+- `CMS-60` unlocks the entire runtime chain (`61`, `62`)
+- `CMS-68` starts the full MDX component chain (`69` through `74`)
+- `CMS-77` is the CLI root for `78`, `79`, `80`, and `87`
+- `CMS-85` is independent and valuable enough to run immediately in parallel
+
+### Recommended Priority Wave 2: Close The Long Chains
+
+Once Wave 1 foundations are active, continue each chain in order:
+
+#### Runtime chain
+
+1. `CMS-61`
+2. `CMS-62`
+
+#### MDX component chain
+
+1. `CMS-69`
+2. `CMS-70`
+3. `CMS-71`
+4. `CMS-72`
+5. `CMS-73`
+6. `CMS-74`
+
+#### CLI chain
+
+1. `CMS-79`
+2. `CMS-80`
+3. `CMS-87`
+4. `CMS-78`
+5. `CMS-81`
+6. `CMS-82`
+7. `CMS-83`
+8. `CMS-84`
+
+Why this CLI ordering:
+
+- `CMS-79`, `CMS-80`, and `CMS-87` sit directly off `CMS-77`
+- `CMS-81` cannot start until `CMS-80`
+- `CMS-82` cannot start until `CMS-81`
+- `CMS-83` and `CMS-84` are tail tasks off the push/manifest path
+- `CMS-78` depends only on `CMS-77`, so it can move earlier or later based on resourcing
+
+### Recommended Priority Wave 3: Studio Content and Admin Flows
+
+Run the Studio content/admin tasks as a parallel product track once their external prerequisites are ready:
+
+- `CMS-65` Studio environment management basics
+- `CMS-66` Studio project switcher
+- `CMS-75` Studio user management UI
+- `CMS-76` Studio API key management UI
+- `CMS-63` locale switcher
+- `CMS-64` translation status indicators
+- `CMS-67` environment-specific field badges
+- `CMS-57` schema mismatch banner / read-only mode
+- `CMS-59` read-only schema browsing
+- `CMS-56` publish flow + version history + diff
+
+Suggested order inside this track:
+
+1. `CMS-65`
+2. `CMS-66`
+3. `CMS-75`
+4. `CMS-76`
+5. `CMS-63`
+6. `CMS-64`
+7. `CMS-67`
+8. `CMS-57`
+9. `CMS-59`
+10. `CMS-56`
+
+Why:
+
+- `65`, `66`, `75`, and `76` provide foundational project/environment/admin surfaces
+- `63 -> 64` is the only strict internal chain here
+- `56`, `57`, and `59` are more specialized experience layers and can safely come after the core Studio navigation/admin surfaces
+
+### Deferred From MVP
+
+Do not put these on the MVP-critical Week 3 path unless you intentionally want deferred work:
+
+- `CMS-58`
+- `CMS-86`
+
+## Short Recommendation
+
+If the goal is to reduce rework and unblock the most Week 3 work quickly:
+
+1. Start `CMS-60`, `CMS-68`, `CMS-77`, and `CMS-85`
+2. Then finish the runtime, MDX, and CLI chains in dependency order
+3. Run the Studio content/admin tasks in parallel as prerequisite readiness allows
+4. Keep `CMS-58` and `CMS-86` out of the MVP path because the roadmap explicitly moved them to deferred work

+# CMS-60 Studio Runtime Loader Design
+
+Date: 2026-03-21
+Task: CMS-60
+
+## Goal
+
+Specify a concrete MVP architecture for `@mdcms/studio` where the package acts as a thin runtime shell that loads a backend-served remote Studio application in `module` mode and hands off all in-app behavior to that remote runtime.
+
+## Canonical Inputs
+
+- `ROADMAP_TASKS.md` CMS-60
+- `docs/specs/README.md`
+- `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
+- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+- `packages/shared/src/lib/contracts/extensibility.ts`
+- `packages/studio/src/lib/studio-component.tsx`
+- `packages/studio/src/lib/remote-module.ts`
+- `apps/server/src/lib/studio-bootstrap.ts`
+
+## Spec Delta
+
+`SPEC-006` and `SPEC-002` need a normative runtime-model update that:
+
+- makes `module` the only supported Studio execution mode for MVP
+- removes `iframe` from the MVP decision surface instead of deferring that decision to a later spike
+- clarifies that the shell only owns bootstrap-time loading and fatal startup failure UI
+- clarifies that the remote runtime is the full Studio application after `mount(...)` succeeds
+- adds `basePath` to the shell-to-remote runtime contract so deep links resolve correctly without framework-specific router adapters
+- defines the runtime-internal composition registry contract and deterministic collision rules
+
+`ROADMAP_TASKS.md` also needs follow-up cleanup because CMS-61 currently reserves the execution-mode decision for later, which conflicts with the approved CMS-60 design direction.
+
+## Scope
+
+### In Scope
+
+- Thin `@mdcms/studio` shell loader behavior
+- Bootstrap fetch, manifest compatibility checks, runtime integrity checks, and remote module loading
+- `module`-only runtime execution
+- `basePath` handoff from shell to remote app
+- Remote-owned Studio app routing and UI state after successful mount
+- Runtime-internal composition surfaces for:
+  - `routes`
+  - `navItems`
+  - `slotWidgets`
+  - `fieldKinds`
+  - `editorNodes`
+  - `actionOverrides`
+  - `settingsPanels`
+- Deterministic collision and fallback behavior for those surfaces
+
+### Out of Scope
+
+- `iframe` execution mode
+- Host-managed Studio routing
+- SSR for the remote Studio application
+- Third-party plugin marketplace semantics
+- Dynamic per-request surface registration through the shell
+- Kill-switch and rollback hardening beyond what CMS-60 needs for startup validation
+
+## Design Decisions
+
+### 1. The Shell Is Only a Loader Host
+
+`@mdcms/studio` should only:
+
+- fetch `/api/v1/studio/bootstrap`
+- validate manifest shape, compatibility, and runtime integrity
+- load the remote runtime entry
+- construct the host bridge
+- provide `apiBaseUrl`, auth context, and `basePath`
+- call `mount(container, ctx)`
+
+The shell should not own Studio navigation, editor flows, route-level loading, or normal application rendering once the remote runtime mounts.
+
+### 2. The Remote Runtime Is the Whole Studio App
+
+The remote bundle should be treated as the full Studio application, not as a set of shell-registered fragments.
+
+Internally, the remote module can render a top-level `StudioApp` component, own its own router, and build its own composition registry, but the public boundary remains:
+
+```ts
+type RemoteStudioModule = {
+  mount: (container: HTMLElement, ctx: StudioMountContext) => () => void;
+};
+```
+
+This keeps the shell contract minimal while still allowing the remote app to be React-driven internally.
+
+### 3. `module` Is the Only MVP Execution Mode
+
+The approved direction is to remove `iframe` from MVP rather than keeping a dual-mode abstraction.
+
+The bootstrap manifest can still include a `mode` field for explicitness and compatibility, but MVP should require `mode: "module"` and reject any other value deterministically.
+
+### 4. Remote App Owns Routing After Startup
+
+The remote Studio app should own browser-path syncing with the History API:
+
+- read `window.location`
+- call `history.pushState` / `history.replaceState`
+- listen to `popstate`
+
+No framework-specific router adapter should be required beyond the host app exposing a catch-all route that renders the shell.
+
+Because deep links do not reveal the Studio subtree root reliably, the shell must provide an explicit `basePath`.
+
+### 5. `basePath` Must Be Explicit
+
+The remote runtime cannot infer whether a deep link such as `/admin/content/posts` is rooted at `/admin`, `/cms/admin`, or another embedding prefix.
+
+`StudioMountContext` should therefore gain:
+
+```ts
+type StudioMountContext = {
+  apiBaseUrl: string;
+  basePath: string;
+  auth: { mode: "cookie" | "token"; token?: string };
+  hostBridge: HostBridgeV1;
+};
+```
+
+This is the only routing input the shell needs to provide.
+
+### 6. Composition Surfaces Stay Inside the Remote Runtime
+
+The shell should not expose host-side `registerX(...)` APIs.
+
+Instead, the remote Studio app should compose its own declarative registry for:
+
+- `routes`
+- `navItems`
+- `slotWidgets`
+- `fieldKinds`
+- `editorNodes`
+- `actionOverrides`
+- `settingsPanels`
+
+This keeps CMS-60 within the first-party runtime model already described in the specs and avoids inventing a broader plugin host API prematurely.
+
+### 7. Collisions Must Be Deterministic and Fail Fast
+
+The remote runtime should validate its registry before first real render.
+
+Rules:
+
+- `routes` use normalized path matching; `/settings` and `/settings/` conflict
+- route parameter aliases that normalize to the same shape also conflict
+- duplicate `fieldKinds`, `editorNodes`, `actionOverrides`, or `settingsPanels` fail startup
+- `slotWidgets` require explicit numeric `priority`
+- `slotWidgets` sort by `priority` descending, then `id` ascending
+- `navItems` sort deterministically by explicit order, then `id`
+- `settings.sidebar` entries must reference registered `settingsPanels`
+
+### 8. Unknown Field Kinds Fallback Safely
+
+Unknown or unregistered Studio field kinds should not crash the remote app.
+
+The remote runtime should:
+
+- render a safe JSON editor fallback
+- emit a structured warning log with the missing field kind id
+- continue rendering the rest of the editor
+
+## Failure Model
+
+### Shell-Owned Fatal Startup Failures
+
+The shell is responsible only for fatal startup errors:
+
+- bootstrap fetch failed
+- bootstrap manifest invalid or incompatible
+- runtime asset load/import failed
+- remote `mount(...)` threw during startup
+
+### Remote-Owned Application Failures
+
+After `mount(...)` succeeds, the remote app owns all user-visible Studio states, including:
+
+- normal loading states
+- empty states
+- forbidden states
+- route-level errors
+- editor failures
+- application navigation
+
+## Verification
+
+Completion should be backed by:
+
+- shell loader tests for bootstrap fetch, compatibility/integrity verification, remote import, and `mount(...)` context handoff
+- shell fatal-startup tests for invalid manifest, integrity mismatch, incompatible versions, and mount failure
+- remote runtime registry tests for normalized route conflicts, duplicate surface failures, deterministic slot ordering, and unknown field-kind fallback
+- a deep-link integration test proving `basePath` handoff works under a non-root embed path
+- `bun run format:check`
+- `bun run check`
+
+## Notes
+
+- `docs/plans/` is local-only in this repository, so this design doc should remain untracked.
+- The current package layout uses `packages/studio`, even though parts of the live spec still refer to `apps/studio`; implementation planning should follow the actual repository layout.

+# CMS-60 Studio Runtime Loader Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Replace the shell-first `@mdcms/studio` embed with a thin module loader that boots a backend-served remote Studio application and enforces deterministic runtime composition rules.
+
+**Architecture:** The shell remains a small client-side host that fetches `/api/v1/studio/bootstrap`, validates the manifest and runtime bytes, creates the host bridge, passes `basePath`, and calls the remote `mount(...)` contract. The remote bundle becomes the full Studio app: it owns routing, application states, and an internal registry for `routes`, `navItems`, `slotWidgets`, `fieldKinds`, `editorNodes`, `actionOverrides`, and `settingsPanels`.
+
+**Tech Stack:** Bun, Nx, TypeScript, React 19, Node test runner, Elysia, `@mdcms/shared`, `@mdcms/studio`
+
+---
+
+### Task 1: Lock the spec and operator-facing contract
+
+**Files:**
+
+- Modify: `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
+- Modify: `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+- Modify: `packages/shared/README.md`
+- Modify: `packages/studio/README.md`
+- Test: none
+
+**Step 1: Re-read the approved design and current Studio specs**
+
+Run: `sed -n '1,260p' docs/specs/SPEC-006-studio-runtime-and-ui.md && sed -n '190,360p' docs/specs/SPEC-002-system-architecture-and-extensibility.md`
+Expected: current specs still mention `iframe | module`, shell-owned UI behavior, and composition surfaces without concrete collision rules
+
+**Step 2: Update `SPEC-006` with the CMS-60 runtime-model delta**
+
+Add or update normative sections for:
+
+- `module` as the only MVP execution mode
+- shell-owned concerns limited to bootstrap, verification, and fatal startup failures
+- remote runtime as the full Studio app after `mount(...)`
+- `basePath` on `StudioMountContext`
+- remote-owned routing under the provided base path
+- composition surfaces and deterministic validation rules
+
+**Step 3: Update `SPEC-002` to match the same architecture**
+
+Remove or rewrite the parts that still defer `iframe` vs `module`, and update the runtime data flow and validation bullets so they match the approved CMS-60 design.
+
+**Step 4: Update the package READMEs**
+
+Document:
+
+- the public shell contract in `@mdcms/studio`
+- `basePath` as required loader input
+- startup-only shell failure states
+- composition-surface validation expectations in `@mdcms/shared`
+
+**Step 5: Run formatting check for the touched docs**
+
+Run: `bun run format:check`
+Expected: PASS
+
+**Step 6: Commit**
+
+```bash
+git add docs/specs/SPEC-002-system-architecture-and-extensibility.md docs/specs/SPEC-006-studio-runtime-and-ui.md packages/shared/README.md packages/studio/README.md
+git commit -m "docs(studio): specify module runtime loader contract"
+```
+
+### Task 2: Tighten the shared Studio runtime contracts
+
+**Files:**
+
+- Modify: `packages/shared/src/lib/contracts/extensibility.ts`
+- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
+- Modify: `packages/shared/src/index.ts` (only if exports need adjustment)
+- Test: `packages/shared/src/lib/contracts/extensibility.test.ts`
+
+**Step 1: Write the failing contract tests**
+
+Add cases covering:
+
+- `StudioMountContext.basePath` required and non-empty
+- bootstrap manifests reject non-`module` modes
+- compatibility helpers still validate strict version bounds
+
+**Step 2: Run the targeted shared-contract test**
+
+Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
+Expected: FAIL on missing `basePath` validation and permissive runtime-mode acceptance
+
+**Step 3: Implement the minimal contract changes**
+
+Update `extensibility.ts` so that:
+
+- `StudioExecutionMode` is `"module"`
+- `StudioMountContext` includes `basePath: string`
+- manifest validation only allows `mode: "module"`
+- existing validators and helpers keep their current error-code behavior
+
+Use a concrete contract shape such as:
+
+```ts
+export type StudioExecutionMode = "module";
+
+export type StudioMountContext = {
+  apiBaseUrl: string;
+  basePath: string;
+  auth: { mode: "cookie" | "token"; token?: string };
+  hostBridge: HostBridgeV1;
+};
+```
+
+**Step 4: Re-run the targeted shared-contract test**
+
+Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/shared/src/lib/contracts/extensibility.ts packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/src/index.ts
+git commit -m "refactor(shared): lock studio runtime to module mode"
+```
+
+### Task 3: Replace the shell-first embed with a loader host
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/studio-component.tsx`
+- Create: `packages/studio/src/lib/studio-loader.ts`
+- Create: `packages/studio/src/lib/studio-loader.test.ts`
+- Modify: `packages/studio/src/index.ts`
+- Test: `packages/studio/src/lib/studio-loader.test.ts`
+
+**Step 1: Write the failing loader tests**
+
+Cover:
+
+- fetches `/api/v1/studio/bootstrap`
+- validates manifest compatibility and runtime integrity before import
+- imports the remote module from the manifest `entryUrl`
+- passes `apiBaseUrl`, `basePath`, auth, and host bridge to `mount(...)`
+- returns fatal startup state when bootstrap fetch, verification, import, or mount fails
+
+Keep the hard-to-mock logic in pure helper functions so the React component remains thin.
+
+**Step 2: Run the targeted loader test**
+
+Run: `bun test packages/studio/src/lib/studio-loader.test.ts`
+Expected: FAIL because the loader host does not exist yet
+
+**Step 3: Implement the minimal loader**
+
+Add a small loader module that:
+
+- resolves `apiBaseUrl` from `config.serverUrl`
+- fetches `/api/v1/studio/bootstrap`
+- loads runtime bytes for integrity verification
+- imports the remote module via `import(/* @vite-ignore */ entryUrl)` or equivalent dynamic ESM path
+- validates the remote contract with `assertRemoteStudioModule(...)`
+- calls `mount(container, ctx)`
+
+Update `Studio` so it becomes a client component that:
+
+- accepts `config`, `basePath`, and optional auth/host-bridge overrides for tests
+- renders only fatal startup UI while the loader is unresolved
+- delegates all normal application UI to the remote runtime after `mount(...)`
+
+**Step 4: Re-run the targeted loader test**
+
+Run: `bun test packages/studio/src/lib/studio-loader.test.ts`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/studio/src/lib/studio-component.tsx packages/studio/src/lib/studio-loader.ts packages/studio/src/lib/studio-loader.test.ts packages/studio/src/index.ts
+git commit -m "feat(studio): add remote runtime loader host"
+```
+
+### Task 4: Build the remote Studio app and runtime registry
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/remote-module.ts`
+- Create: `packages/studio/src/lib/remote-studio-app.tsx`
+- Create: `packages/studio/src/lib/runtime-registry.ts`
+- Create: `packages/studio/src/lib/runtime-registry.test.ts`
+- Modify: `packages/studio/src/lib/bootstrap-verification.test.ts` (only if startup-path coverage needs extension)
+- Test: `packages/studio/src/lib/runtime-registry.test.ts`
+
+**Step 1: Write the failing runtime-registry tests**
+
+Cover:
+
+- normalized route conflicts such as `/settings` vs `/settings/`
+- param-shape conflicts such as duplicate normalized content-detail routes
+- duplicate `fieldKinds`, `editorNodes`, `actionOverrides`, and `settingsPanels`
+- `slotWidgets` missing explicit `priority`
+- deterministic slot ordering by `priority` descending then `id` ascending
+- unknown field kind falling back to a JSON editor descriptor and emitting a structured warning
+
+**Step 2: Run the targeted registry test**
+
+Run: `bun test packages/studio/src/lib/runtime-registry.test.ts`
+Expected: FAIL because the registry implementation does not exist yet
+
+**Step 3: Implement the minimal remote app and registry**
+
+Create a runtime-owned app that:
+
+- mounts from `remote-module.ts`
+- reads `ctx.basePath`
+- owns browser history and route parsing inside the remote app
+- builds and validates the composition registry before first render
+- renders the default Studio surfaces through that registry
+- uses a safe JSON editor fallback for unknown field kinds
+
+Keep the route and registry validation logic outside React where possible so tests stay deterministic and do not require a browser-heavy harness.
+
+**Step 4: Re-run the targeted registry test**
+
+Run: `bun test packages/studio/src/lib/runtime-registry.test.ts`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/studio/src/lib/remote-module.ts packages/studio/src/lib/remote-studio-app.tsx packages/studio/src/lib/runtime-registry.ts packages/studio/src/lib/runtime-registry.test.ts packages/studio/src/lib/bootstrap-verification.test.ts
+git commit -m "feat(studio): add remote studio runtime registry"
+```
+
+### Task 5: Remove shell-managed routing from the example embed and stale shell tests
+
+**Files:**
+
+- Modify: `apps/studio-example/app/admin/[[...path]]/page.tsx`
+- Modify: `packages/studio/src/lib/studio.test.ts`
+- Test: `packages/studio/src/lib/studio.test.ts`
+
+**Step 1: Write or update the failing embed tests**
+
+Refocus `studio.test.ts` around the new shell boundary:
+
+- fatal startup UI behavior only
+- no shell-managed content/document route logic after remote mount
+- `basePath` handoff into the loader path
+
+Drop assertions that are now remote-runtime responsibilities, such as shell-level route resolution and document-shell rendering.
+
+**Step 2: Run the targeted shell test**
+
+Run: `bun test packages/studio/src/lib/studio.test.ts`
+Expected: FAIL until the old shell assumptions are removed
+
+**Step 3: Update the example embed page**
+
+Change the example so it:
+
+- stops preloading route-specific Studio state in the host page
+- renders the shell with an explicit `basePath`
+- leaves routing and document loading to the remote runtime
+
+The result should be closer to:
+
+```tsx
+export default function AdminCatchAllPage() {
+  return <Studio config={config} basePath="/admin" />;
+}
+```
+
+**Step 4: Re-run the targeted shell test**
+
+Run: `bun test packages/studio/src/lib/studio.test.ts`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add apps/studio-example/app/admin/[[...path]]/page.tsx packages/studio/src/lib/studio.test.ts
+git commit -m "refactor(studio): remove host-managed studio routing"
+```
+
+### Task 6: Verify the full CMS-60 slice
+
+**Files:**
+
+- Modify: none unless verification exposes follow-up fixes
+- Test: all touched package tests
+
+**Step 1: Run targeted Studio tests**
+
+Run: `bun test packages/studio/src/lib/studio-loader.test.ts packages/studio/src/lib/runtime-registry.test.ts packages/studio/src/lib/studio.test.ts packages/studio/src/lib/bootstrap-verification.test.ts`
+Expected: PASS
+
+**Step 2: Run targeted shared-contract tests**
+
+Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
+Expected: PASS
+
+**Step 3: Run formatting and workspace checks**
+
+Run: `bun run format:check && bun run check`
+Expected: PASS
+
+**Step 4: Inspect git status**
+
+Run: `git status --short`
+Expected: task-scoped tracked changes only; local-only paths such as `docs/plans/` remain unstaged
+
+**Step 5: Final commit if verification fixes were required**
+
+```bash
+git add <task-scoped-files>
+git commit -m "test(studio): finalize cms-60 runtime loader verification"

+# CMS-61 Studio Runtime Decision Reconciliation Design
+
+Date: 2026-03-23
+Task: CMS-61
+
+## Goal
+
+Reconcile the stale Studio execution-mode decision record with the live module-only Studio runtime contract that is already implemented and specified elsewhere in the repository.
+
+## Canonical Inputs
+
+- `ROADMAP_TASKS.md` CMS-61
+- `docs/specs/README.md`
+- `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
+- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+- `docs/adrs/ADR-003-studio-delivery-approach-c.md`
+- `packages/studio/README.md`
+
+## Spec Delta
+
+No owning-spec delta is required for this reconciliation slice.
+
+The authoritative product contract is already module-only in the owning specs:
+
+- `SPEC-002` says Studio runtime execution is `module`-only in MVP.
+- `SPEC-006` defines `StudioExecutionMode` as `module` and states that `module` is the only supported Studio execution mode in MVP.
+
+The required delta is in the architectural rationale record:
+
+- `ADR-003` still says the execution-mode choice is open between `iframe` and `module`.
+- `ADR-003` must be reconciled so the decision record matches the live spec and current implementation direction.
+
+## Scope
+
+### In Scope
+
+- Update `ADR-003` to state that MVP execution mode is `module`.
+- Remove stale wording that leaves the execution mode undecided.
+- Keep the ADR rationale aligned with host bridge and MDX preview requirements already reflected in the specs.
+
+### Out of Scope
+
+- Any new runtime implementation work
+- Any `iframe` spike or proof-of-concept
+- Changes to the owning specs beyond confirming they already contain the final contract
+- New test coverage unless verification reveals a docs inconsistency that must be fixed
+
+## Design Decisions
+
+### 1. Treat This as ADR Reconciliation, Not Product Redesign
+
+`CMS-61` is being interpreted here as a documentation reconciliation slice only. The owning specs already carry the normative decision, so the ADR should record the same outcome instead of reopening the choice.
+
+### 2. Keep the Change Focused to `ADR-003`
+
+The smallest correct change is to update the stale ADR language in place:
+
+- replace the open decision wording with a final `module` decision
+- explain that the host bridge and MDX preview requirements fit the in-process module model for MVP
+- remove the statement that the final mode is still pending future spikes
+
+### 3. Use Existing Repo Evidence Rather Than Inventing New Spike Artifacts
+
+The repository already contains enough internal evidence for a reconciliation-only slice:
+
+- the owning specs are module-only
+- the package README is module-only
+- the runtime contracts and tests reject non-module manifests
+
+This slice should not manufacture a fake dual-mode evaluation artifact inside the codebase.
+
+## Verification
+
+Completion should be backed by:
+
+- confirming `ADR-003` no longer states the decision is open
+- confirming the canonical docs set no longer disagrees about MVP execution mode
+- `bun run format:check`
+
+## Notes
+
+- `docs/plans/` is local-only in this repository, so this design doc should remain untracked.

+# CMS-61 Studio Runtime Reconciliation Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Reconcile the stale Studio delivery ADR with the already-approved module-only Studio runtime contract.
+
+**Architecture:** This is a docs-only change. Update the ADR so its rationale and consequences match the module-only decision already owned by the live specs, then verify that no canonical docs still present the execution mode as undecided.
+
+**Tech Stack:** Markdown docs, ripgrep, Bun workspace verification commands
+
+---
+
+### Task 1: Reconcile ADR-003
+
+**Files:**
+
+- Modify: `docs/adrs/ADR-003-studio-delivery-approach-c.md`
+- Verify against: `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
+- Verify against: `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+- Verify against: `packages/studio/README.md`
+
+**Step 1: Update the stale ADR language**
+
+Change the security/delivery and consequence sections so they no longer describe `iframe` vs `module` as an open MVP choice.
+
+**Step 2: Align the rationale with the live contract**
+
+State that MVP uses `module` execution because it aligns with the capability-limited host bridge, MDX preview integration, and the existing thin-loader architecture.
+
+**Step 3: Run targeted consistency checks**
+
+Run: `rg -n "decision is open|stays open|iframe.*module|execution mode remains" docs/adrs docs/specs packages/studio`
+Expected: no remaining stale open-decision wording in canonical docs for the MVP Studio execution mode
+
+**Step 4: Run format verification**
+
+Run: `bun run format:check`
+Expected: PASS
+
+**Step 5: Review git status**
+
+Run: `git status --short`
+Expected: only the intended tracked docs change is modified, and local-only files remain untracked
+
+## Notes
+
+- `docs/plans/` is local-only in this repository, so this plan should remain untracked.

+# CMS-62 Studio Runtime Hardening Design
+
+Date: 2026-03-23
+Task: CMS-62
+
+## Goal
+
+Implement the selected `module` Studio runtime path as the only production mode and add deterministic startup recovery behavior, operator disable behavior, and regression coverage for runtime validation, authorization filtering, and MDX host-bridge preview behavior.
+
+## Canonical Inputs
+
+- `ROADMAP_TASKS.md` CMS-62
+- `docs/specs/README.md`
+- `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
+- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+- `docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
+- `apps/server/README.md`
+- `packages/studio/README.md`
+
+## Spec Delta
+
+The execution mode itself does not change. The owning spec already defines MVP Studio runtime execution as `module` only.
+
+The required spec delta is the startup recovery contract:
+
+- `SPEC-006` must define server-owned publication state with `active`, optional `lastKnownGood`, and operator disable state.
+- `SPEC-006` must define bootstrap success as a startup envelope, not a raw manifest-only payload.
+- `SPEC-006` must define a deterministic recovery retry shape for client-detected runtime rejection:
+  - `rejectedBuildId`
+  - `rejectionReason` in `integrity | signature | compatibility`
+- `SPEC-006` must define deterministic disabled/unavailable outcomes:
+  - `STUDIO_RUNTIME_DISABLED`
+  - `STUDIO_RUNTIME_UNAVAILABLE`
+- `SPEC-002` should align its testing/architecture language to clarify that build selection remains server-owned and the shell only retries bootstrap once with rejection context.
+
+## Scope
+
+### In Scope
+
+- Keep `module` as the only production runtime mode.
+- Add server-owned rollback to `lastKnownGood`.
+- Add an operator kill-switch path for Studio startup.
+- Keep `/api/v1/studio/bootstrap` as the single bootstrap endpoint.
+- Add one bootstrap retry from the shell when runtime validation rejects a served build.
+- Add regression coverage for integrity/signature/compatibility rejection, fallback selection, disabled/unavailable behavior, unauthorized action visibility, forced server rejection, and MDX host-bridge preview.
+
+### Out of Scope
+
+- Any production `iframe` runtime path.
+- Browser-local caching of last-known-good builds.
+- A new admin UI or public API for toggling the kill switch.
+- A general deployment/promotion system beyond the minimum publication state required for bootstrap decisions.
+
+## Design Decisions
+
+### 1. Server Owns Publication Selection
+
+The server decides which Studio build is safe to serve. The shell never chooses between active and fallback builds on its own and never persists fallback state in the browser.
+
+Server publication state is modeled as:
+
+- `active` build
+- optional `lastKnownGood` build
+- operator `killSwitch`
+
+This preserves the existing architecture: the server publishes the Studio runtime, and the shell only validates and mounts the returned runtime.
+
+### 2. Keep a Single Bootstrap Endpoint
+
+`GET /api/v1/studio/bootstrap` remains the only startup endpoint.
+
+Initial startup request remains body-less.
+
+If the shell rejects a served build during integrity/signature/compatibility validation, it retries the same endpoint once with rejection context:
+
+- `rejectedBuildId=<buildId>`
+- `rejectionReason=integrity|signature|compatibility`
+
+The server uses that context to decide whether to serve `lastKnownGood` or return a deterministic disabled/unavailable response.
+
+### 3. Bootstrap Success Becomes a Startup Envelope
+
+Instead of returning only `{ data: StudioBootstrapManifest }`, bootstrap success returns a startup envelope:
+
+```ts
+type StudioBootstrapReadyResponse = {
+  data: {
+    status: "ready";
+    source: "active" | "lastKnownGood";
+    manifest: StudioBootstrapManifest;
+    recovery?: {
+      rejectedBuildId: string;
+      rejectionReason: "integrity" | "signature" | "compatibility";
+    };
+  };
+};
+```
+
+This keeps the public surface small while making fallback usage explicit and testable.
+
+### 4. Disabled and Unavailable Stay as Error Envelopes
+
+Bootstrap remains deterministic when Studio cannot be started:
+
+- `503 STUDIO_RUNTIME_DISABLED`
+  - operator kill switch is enabled
+- `503 STUDIO_RUNTIME_UNAVAILABLE`
+  - no safe build can be served
+
+The shell renders deterministic startup error UI for those outcomes and does not retry further.
+
+### 5. The Shell Retries Once
+
+The shell startup flow becomes:
+
+1. Fetch bootstrap.
+2. Fetch runtime asset.
+3. Validate integrity/signature/compatibility.
+4. Mount runtime if validation passes.
+5. If validation fails and the failure reason is retryable, re-request bootstrap once with rejection context.
+6. If the retry returns a ready payload, validate and mount the fallback build.
+7. If the retry returns disabled/unavailable, or if the fallback build also fails validation, render deterministic startup failure UI and stop.
+
+There is no infinite retry loop.
+
+### 6. Operator Path Is Config-Driven in MVP
+
+CMS-62 does not add a new mutation API for Studio publication control.
+
+The kill switch is server configuration or environment driven. `lastKnownGood` is the previously promoted verified publication snapshot held by the server runtime/publication layer.
+
+This satisfies the acceptance criterion without widening the operator surface beyond MVP needs.
+
+### 7. Selected-Mode Regression Coverage Must Exercise Real Host-Bridge and Authorization Paths
+
+Regression coverage should prove more than contract parsing:
+
+- the `module` mode loader handles happy-path startup
+- invalid runtime bytes/signature/compatibility trigger the one-shot bootstrap retry
+- fallback builds are served from `lastKnownGood`
+- disabled/unavailable outcomes are deterministic
+- Studio-visible actions come only from the authorization-filtered catalog
+- forced route invocation is still rejected by the server
+- the remote runtime calls `hostBridge.renderMdxPreview(...)` on the document/editor path
+
+## Implementation Notes
+
+- Shared contracts should own the new bootstrap ready envelope types and validators.
+- Server code should expose publication-state helpers without introducing circular package dependencies.
+- The remote runtime can stay thin, but it should include one minimal document-route preview surface and one minimal action strip driven by the filtered action catalog so the tests cover real selected-mode behavior.
+
+## Verification
+
+The task is complete when the repository can demonstrate:
+
+- module-only runtime behavior remains the only production path
+- bootstrap recovery is deterministic and server-owned
+- the shell retries bootstrap once on validation rejection and stops cleanly afterward
+- unauthorized actions are absent from Studio-visible action rendering and still rejected by the server when forced
+- MDX preview host-bridge flow is exercised in selected mode
+- `bun run format:check`
+- `bun run check`
+- targeted runtime regression tests in `shared`, `server`, and `studio`
+- `bun run studio:embed:smoke`
+
+## Notes
+
+- `docs/plans/` is local-only in this repository and must remain untracked.

+# CMS-62 Studio Runtime Hardening Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Implement server-owned Studio runtime rollback/disable behavior for the selected `module` mode and add deterministic regression coverage for bootstrap recovery, authorization-filtered action visibility, and MDX host-bridge preview.
+
+**Architecture:** Keep `module` as the only production runtime mode. The server owns Studio publication state (`active`, optional `lastKnownGood`, kill switch) and returns one bootstrap outcome at a time; the shell validates the served runtime, retries bootstrap once with rejection context on retryable validation failures, and otherwise renders deterministic startup error UI. Selected-mode regression coverage should exercise the real loader, bootstrap route, filtered action catalog, and host bridge path rather than isolated contract stubs only.
+
+**Tech Stack:** Bun, TypeScript, React 19, Elysia, shared Zod runtime contracts, node:test, Nx
+
+---
+
+> Local workflow note: `docs/plans/` is local-only and must remain untracked. Do not include this plan file in commits.
+
+### Task 1: Update the spec-owned runtime recovery contract
+
+**Files:**
+
+- Modify: `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+- Modify: `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
+- Modify: `packages/studio/README.md`
+- Modify: `apps/server/README.md`
+
+**Step 1: Patch the owning spec with the new bootstrap startup envelope**
+
+Add the server-owned publication state and bootstrap ready envelope to `SPEC-006`, including the retry query params and the disabled/unavailable error outcomes.
+
+```ts
+export type StudioBootstrapRejectionReason =
+  | "integrity"
+  | "signature"
+  | "compatibility";
+
+export type StudioBootstrapReadyResponse = {
+  data: {
+    status: "ready";
+    source: "active" | "lastKnownGood";
+    manifest: StudioBootstrapManifest;
+    recovery?: {
+      rejectedBuildId: string;
+      rejectionReason: StudioBootstrapRejectionReason;
+    };
+  };
+};
+```
+
+**Step 2: Align the supporting architecture and operator docs**
+
+Update `SPEC-002`, `packages/studio/README.md`, and `apps/server/README.md` so they all describe:
+
+- server-owned `active` vs `lastKnownGood`
+- one-shot bootstrap retry with rejection context
+- kill-switch via server config/env
+- `module` remaining the only production mode
+
+**Step 3: Run a targeted terminology check**
+
+Run:
+
+```bash
+rg -n "lastKnownGood|rejectedBuildId|rejectionReason|STUDIO_RUNTIME_DISABLED|STUDIO_RUNTIME_UNAVAILABLE" docs/specs/SPEC-006-studio-runtime-and-ui.md docs/specs/SPEC-002-system-architecture-and-extensibility.md packages/studio/README.md apps/server/README.md
+```
+
+Expected: each new runtime-recovery term appears in the updated docs.
+
+**Step 4: Run format verification**
+
+Run:
+
+```bash
+bun run format:check
+```
+
+Expected: PASS
+
+**Step 5: Commit the spec/docs delta**
+
+```bash
+git add docs/specs/SPEC-006-studio-runtime-and-ui.md docs/specs/SPEC-002-system-architecture-and-extensibility.md packages/studio/README.md apps/server/README.md
+git commit -m "docs(studio): define runtime recovery contract"
+```
+
+### Task 2: Add shared bootstrap startup contracts and validators
+
+**Files:**
+
+- Modify: `packages/shared/src/lib/contracts/extensibility.ts`
+- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
+- Modify: `packages/shared/src/index.ts`
+- Modify: `packages/shared/README.md`
+
+**Step 1: Write the failing shared-contract tests**
+
+Add tests for:
+
+- accepting a ready bootstrap envelope with `source: "active"`
+- accepting a fallback envelope with `source: "lastKnownGood"` and `recovery`
+- rejecting invalid `rejectionReason`
+- rejecting malformed `source`
+
+```ts
+const ready = {
+  data: {
+    status: "ready",
+    source: "lastKnownGood",
+    manifest: validManifest,
+    recovery: {
+      rejectedBuildId: "bad-build",
+      rejectionReason: "integrity",
+    },
+  },
+};
+
+assertStudioBootstrapReadyResponse(ready);
+```
+
+**Step 2: Run the targeted shared tests to verify failure**
+
+Run:
+
+```bash
+bun --cwd packages/shared test ./src/lib/contracts/extensibility.test.ts
+```
+
+Expected: FAIL because the new startup-envelope contract is not implemented yet.
+
+**Step 3: Implement the minimal shared types and runtime assertions**
+
+Add:
+
+- `StudioBootstrapRejectionReason`
+- `StudioBootstrapReadyPayload`
+- `StudioBootstrapReadyResponse`
+- `assertStudioBootstrapReadyResponse(...)`
+
+Export them through `packages/shared/src/index.ts` and document the ready-envelope contract in `packages/shared/README.md`.
+
+**Step 4: Re-run the targeted shared tests**
+
+Run:
+
+```bash
+bun --cwd packages/shared test ./src/lib/contracts/extensibility.test.ts
+```
+
+Expected: PASS
+
+**Step 5: Commit the shared-contract slice**
+
+```bash
+git add packages/shared/src/lib/contracts/extensibility.ts packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/src/index.ts packages/shared/README.md
+git commit -m "feat(shared): add studio bootstrap ready contract"
+```
+
+### Task 3: Implement server publication state and bootstrap decision flow
+
+**Files:**
+
+- Modify: `apps/server/src/lib/env.ts`
+- Modify: `apps/server/src/lib/env.test.ts`
+- Modify: `apps/server/src/lib/studio-bootstrap.ts`
+- Modify: `apps/server/src/lib/studio-bootstrap.test.ts`
+- Modify: `apps/server/src/lib/server.ts`
+- Modify: `apps/server/src/lib/health.test.ts`
+- Modify: `apps/server/src/lib/runtime-with-modules.test.ts`
+
+**Step 1: Write the failing server tests**
+
+Cover:
+
+- kill-switch env parsing
+- bootstrap returns ready envelope for `active`
+- bootstrap returns ready envelope for `lastKnownGood` when retry query params reject the active build
+- bootstrap returns `503 STUDIO_RUNTIME_DISABLED` when the kill switch is enabled
+- bootstrap returns `503 STUDIO_RUNTIME_UNAVAILABLE` when no safe build exists
+
+Example bootstrap assertion:
+
+```ts
+assert.deepEqual(body.data, {
+  status: "ready",
+  source: "lastKnownGood",
+  manifest: fallbackManifest,
+  recovery: {
+    rejectedBuildId: activeManifest.buildId,
+    rejectionReason: "integrity",
+  },
+});
+```
+
+**Step 2: Run the targeted server tests to verify failure**
+
+Run:
+
+```bash
+bun --cwd apps/server test ./src/lib/env.test.ts ./src/lib/studio-bootstrap.test.ts ./src/lib/health.test.ts ./src/lib/runtime-with-modules.test.ts
+```
+
+Expected: FAIL because the server still serves a raw manifest-only bootstrap payload and has no kill-switch/publication fallback logic.
+
+**Step 3: Implement the minimal server publication-state path**
+
+Add:
+
+- a parsed env/config flag for the operator kill switch
+- a publication-state shape in `studio-bootstrap.ts` that can hold `active` and optional `lastKnownGood`
+- bootstrap route logic in `server.ts` that:
+  - returns active ready payload on normal startup
+  - returns fallback ready payload when retry query params reject the active build and `lastKnownGood` exists
+  - returns deterministic `503` error envelopes when disabled or unavailable
+
+Do not add a new public mutation API for this task.
+
+**Step 4: Re-run the targeted server tests**
+
+Run:
+
+```bash
+bun --cwd apps/server test ./src/lib/env.test.ts ./src/lib/studio-bootstrap.test.ts ./src/lib/health.test.ts ./src/lib/runtime-with-modules.test.ts
+```
+
+Expected: PASS
+
+**Step 5: Commit the server bootstrap slice**
+
+```bash
+git add apps/server/src/lib/env.ts apps/server/src/lib/env.test.ts apps/server/src/lib/studio-bootstrap.ts apps/server/src/lib/studio-bootstrap.test.ts apps/server/src/lib/server.ts apps/server/src/lib/health.test.ts apps/server/src/lib/runtime-with-modules.test.ts
+git commit -m "feat(server): add studio runtime recovery bootstrap"
+```
+
+### Task 4: Implement shell retry-on-rejection and deterministic disabled-state UI
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/studio-loader.ts`
+- Modify: `packages/studio/src/lib/studio-loader.test.ts`
+- Modify: `packages/studio/src/lib/studio-component.tsx`
+- Modify: `packages/studio/src/lib/studio.test.ts`
+
+**Step 1: Write the failing loader and shell tests**
+
+Add tests for:
+
+- parsing the new ready bootstrap envelope
+- retrying bootstrap once with `rejectedBuildId` and `rejectionReason=integrity`
+- surfacing `STUDIO_RUNTIME_DISABLED`
+- surfacing `STUDIO_RUNTIME_UNAVAILABLE`
+- stopping after one retry instead of looping
+
+Example retry expectation:
+
+```ts
+assert.deepEqual(fetchLog, [
+  "http://localhost:4000/api/v1/studio/bootstrap",
+  "http://localhost:4000/api/v1/studio/assets/active-build/runtime.mjs",
+  "http://localhost:4000/api/v1/studio/bootstrap?rejectedBuildId=active-build&rejectionReason=integrity",
+  "http://localhost:4000/api/v1/studio/assets/fallback-build/runtime.mjs",
+]);
+```
+
+**Step 2: Run the targeted studio loader tests to verify failure**
+
+Run:
+
+```bash
+bun --cwd packages/studio test ./src/lib/studio-loader.test.ts ./src/lib/studio.test.ts
+```
+
+Expected: FAIL because the loader still expects `{ data: StudioBootstrapManifest }` and has no retry/disabled logic.
+
+**Step 3: Implement the minimal loader retry path**
+
+Update the loader to:
+
+- parse `StudioBootstrapReadyResponse`
+- classify retryable validation failures as `integrity`, `signature`, or `compatibility`
+- re-request bootstrap once with rejection query params
+- stop on non-retryable failures or after a failed fallback load
+
+**Step 4: Update deterministic startup error descriptions**
+
+Extend `describeStudioStartupError(...)` and the startup shell markup so disabled/unavailable states render explicit operator-facing copy instead of falling through to generic crash text.
+
+**Step 5: Re-run the targeted studio loader tests**
+
+Run:
+
+```bash
+bun --cwd packages/studio test ./src/lib/studio-loader.test.ts ./src/lib/studio.test.ts
+```
+
+Expected: PASS
+
+**Step 6: Commit the shell recovery slice**
+
+```bash
+git add packages/studio/src/lib/studio-loader.ts packages/studio/src/lib/studio-loader.test.ts packages/studio/src/lib/studio-component.tsx packages/studio/src/lib/studio.test.ts
+git commit -m "feat(studio): retry bootstrap on runtime rejection"
+```
+
+### Task 5: Add selected-mode MDX preview and authorization-filtered action fixtures
+
+**Files:**

+- Modify: `packages/studio/src/lib/remote-studio-app.test.ts`
+- Modify: `packages/studio/src/lib/action-catalog-adapter.ts`
+- Modify: `apps/server/src/lib/health.test.ts`
+
+**Step 1: Write the failing remote-runtime tests**
+
+Add tests that prove:
+
+- document/editor route calls `context.hostBridge.renderMdxPreview(...)`
+- preview cleanup runs on route change/unmount
+- Studio action rendering uses only the filtered catalog returned by `/api/v1/actions`
+- hidden actions do not appear in the rendered action strip
+
+Example host-bridge assertion:
+
+```ts
+assert.deepEqual(previewCalls, [
+  {
+    componentName: "HeroBanner",
+    props: { title: "Launch" },
+    key: "preview:content.document",
+  },
+]);
+```
+
+**Step 2: Run the targeted remote-runtime tests to verify failure**
+
+Run:
+
+```bash
+bun --cwd packages/studio test ./src/lib/remote-studio-app.test.ts
+```
+
+Expected: FAIL because the remote runtime does not yet exercise the host bridge or render action UI from the filtered action catalog.
+
+**Step 3: Implement the minimal remote-runtime behavior**
+
+Add:
+
+- a small document-route preview surface that calls `renderMdxPreview(...)`
+- a small action strip driven by `createStudioActionCatalogAdapter(...)`
+- deterministic loading/error fallbacks that never synthesize hidden actions locally
+
+Keep the implementation minimal and selected-mode only.
+
+**Step 4: Re-run the targeted remote-runtime tests**
+
+Run:
+
+```bash
+bun --cwd packages/studio test ./src/lib/remote-studio-app.test.ts
+```
+
+Expected: PASS
+
+**Step 5: Re-run the existing forced-invocation server test**
+
+Run:
+
+```bash
+bun --cwd apps/server test ./src/lib/health.test.ts
+```
+
+Expected: PASS, including the hidden-action forced-route rejection case.
+
+**Step 6: Commit the selected-mode fixture slice**
+
+```bash
+git add packages/studio/src/lib/remote-studio-app.tsx packages/studio/src/lib/remote-studio-app.test.ts packages/studio/src/lib/action-catalog-adapter.ts apps/server/src/lib/health.test.ts

+# CMS-68 Local MDX Component Catalog Design
+
+> Local-only planning note. This file is not canonical product documentation and should remain uncommitted.
+
+## Summary
+
+`CMS-68` should no longer be implemented as a backend schema-sync feature.
+The embedded Studio runs inside the host app and must resolve the host app's
+actual React MDX components locally. That makes component discovery, preview,
+and custom props-editor resolution a host-local runtime concern, not a server
+registry concern.
+
+## Problem
+
+The current specs drifted into a model where schema sync persists optional
+`extractedComponents` metadata on the backend and implies that Studio reads
+component registration metadata from the server.
+
+That conflicts with the approved embedding architecture:
+
+- Studio is embedded in the host app.
+- MDX preview should use the host app's real React components.
+- The backend stores MDX content and does not need to understand component
+  implementations.
+
+## Approved Direction
+
+### Source of truth
+
+`mdcms.config.ts` remains the single source of truth for MDX component
+registration.
+
+### Backend scope
+
+The backend does not persist, validate, or expose a component catalog.
+
+- Remove `extractedComponents` from the schema-sync contract.
+- Keep schema sync focused on content type registry state only.
+- Treat MDX component usage as opaque content stored in markdown/MDX bodies.
+
+### Studio runtime scope
+
+The embedded Studio runtime reads component registrations from local config and
+uses local runtime loaders for executable pieces.
+
+- Metadata for insertion/edit UI comes from `config.components`.
+- Actual preview components are resolved locally in the host bundle.
+- Custom props editors are resolved locally in the host bundle.
+
+## Public API Shape
+
+The public embed story should stay simple and avoid manual bridge plumbing or
+codegen.
+
+Supported embedding pattern:
+
+```tsx
+"use client";
+
+import { Studio } from "@mdcms/studio";
+import config from "../../../mdcms.config";
+
+export default function AdminPage() {
+  return <Studio config={config} basePath="/admin" />;
+}
+```
+
+`Studio` should accept a config object that includes MDX component metadata plus
+client-only loader callbacks on each component registration.
+
+Example authoring shape:
+
+```ts
+components: [
+  {
+    name: "Chart",
+    importPath: "@/components/mdx/Chart",
+    load: () => import("@/components/mdx/Chart").then((m) => m.Chart),
+    description: "Renders a data chart",
+    propHints: {
+      color: { widget: "color-picker" },
+    },
+  },
+  {
+    name: "PricingTable",
+    importPath: "@/components/mdx/PricingTable",
+    load: () =>
+      import("@/components/mdx/PricingTable").then((m) => m.PricingTable),
+    loadPropsEditor: () =>
+      import("@/components/mdx/PricingTable.editor").then((m) => m.default),
+    description: "Pricing table",
+  },
+];
+```
+
+## Internal Wiring
+
+The current host-bridge concept remains useful as an internal runtime boundary
+between the shell and the dynamically loaded Studio bundle, but it should not
+be user-authored boilerplate for MDX components.
+
+Implementation direction:
+
+- `@mdcms/studio` derives local MDX catalog metadata from `config.components`.
+- `@mdcms/studio` builds any internal bridge/capability objects itself.
+- The dynamically loaded Studio runtime receives:
+  - serializable MDX catalog metadata
+  - internal executable callbacks for preview/editor resolution
+
+## Consequences
+
+### Benefits
+
+- No backend component sync.
+- No component registry persistence in the database.
+- One source of truth for component registration.
+- No extra binding boilerplate beyond the authored config.
+- No code generation step.
+
+### Tradeoffs
+
+- The supported embed pattern for MDX component features becomes client-side,
+  because loader callbacks are not server-to-client serializable.
+- `mdcms.config.ts` becomes responsible for both metadata and runtime loader
+  declarations for components.
+- `createStudioEmbedConfig(...)` cannot remain the only documented path for
+  MDX-aware embedding if it strips runtime loaders away.
+
+## Required Spec Delta
+
+### SPEC-004
+
+- Remove `extractedComponents` from registry model prose.
+- Remove `extractedComponents?` from `PUT /api/v1/schema`.
+- Remove any examples that imply backend persistence of MDX component metadata.
+
+### SPEC-006
+
+- Update the embed contract to document client-side embedding for MDX component
+  features.
+- Expand the shell/runtime contract so the remote runtime receives local MDX
+  catalog metadata and internal local resolvers from the shell package, not the
+  backend.
+
+### SPEC-007
+
+- Replace "props are sent to the server" language with local embedded-Studio
+  extraction/runtime language.
+- Define the local component-catalog contract owned by the embedded Studio
+  runtime.
+- Clarify that preview and custom editor resolution are host-local concerns.
+
+## Acceptance Mapping
+
+- "Registered components are persisted and queryable by Studio" is no longer the
+  right architecture and should be reinterpreted as "registered components are
+  locally available to the embedded Studio runtime from `mdcms.config.ts`."
+- "Foundational behavior is reusable by dependent tasks" maps to:
+  - stable local component registration contract
+  - stable extracted prop metadata shape
+  - stable preview/editor loader hooks for downstream MDX tasks

+# CMS-68 Local MDX Component Catalog Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Replace the server-backed MDX component sync model with a host-local Studio component catalog sourced from `mdcms.config.ts`, while keeping the backend ignorant of component implementations.
+
+**Architecture:** Update the canonical specs first so they describe a local embedded-Studio component catalog instead of backend schema-sync persistence. Then extend the shared config contract to support client-only component loader callbacks, plumb that data through the Studio shell/runtime boundary, and delete the obsolete backend `extractedComponents` schema-sync contract and storage.

+### Task 1: Update Canonical Specs Before Code Changes
+
+**Files:**
+
+- Modify: `docs/specs/SPEC-004-schema-system-and-sync.md`
+- Modify: `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+- Modify: `docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
+- Reference: `docs/adrs/ADR-003-studio-delivery-approach-c.md`
+
+**Step 1: Edit the schema-sync spec to remove backend component catalog sync**
+
+- Remove `optional extractedComponents` from the registry model section.
+- Remove `extractedComponents?` from the `PUT /api/v1/schema` contract table.
+- Keep schema sync narrowly about content type registry state.
+
+**Step 2: Edit the Studio runtime spec to define local component catalog delivery**
+
+- Document that MDX-aware Studio embedding is client-side when loader callbacks
+  are used.
+- Document that the shell/runtime boundary carries local MDX catalog metadata
+  and local executable resolvers from the host bundle.
+- Keep the backend runtime publication model unchanged.
+
+**Step 3: Edit the MDX spec to move component extraction fully local**
+
+- Replace "sent to the server" language with "consumed by the embedded Studio
+  runtime".
+- Define the local component-catalog contract and loader responsibilities.
+- Clarify that preview and custom editor resolution happen locally in the host
+  app context.
+
+**Step 4: Review the three specs together for consistency**
+
+Run: `rg -n "extractedComponents|sent to the server|queryable by Studio|schema sync" docs/specs/SPEC-004-schema-system-and-sync.md docs/specs/SPEC-006-studio-runtime-and-ui.md docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
+
+Expected: no remaining contradictory language about backend component-catalog sync.
+
+**Step 5: Commit**
+
+```bash
+git add docs/specs/SPEC-004-schema-system-and-sync.md docs/specs/SPEC-006-studio-runtime-and-ui.md docs/specs/SPEC-007-editor-mdx-and-collaboration.md

+
+### Task 2: Extend Shared Config Contracts for Local Runtime Loaders
+
+**Files:**
+
+- Modify: `packages/shared/src/lib/contracts/config.ts`
+- Modify: `packages/shared/src/lib/contracts/config.test.ts`
+- Modify: `packages/shared/README.md`
+
+**Step 1: Write the failing tests for component loader authoring**
+
+Add tests in `packages/shared/src/lib/contracts/config.test.ts` that assert:
+
+- `defineConfig({... components: [...] })` accepts component registrations with
+  optional `load` and `loadPropsEditor` function fields.
+- `parseMdcmsConfig(...)` continues to normalize serializable component metadata
+  and ignores runtime-only loader callbacks.
+
+Example test shape:
+
+```ts
+test("parseMdcmsConfig ignores runtime-only component loader callbacks", () => {
+  const config = defineConfig({
+    project: "marketing-site",
+    serverUrl: "http://localhost:4000",
+    components: [
+      {
+        name: "Chart",
+        importPath: "@/components/mdx/Chart",
+        load: async () => null,
+        loadPropsEditor: async () => null,
+      },
+    ],
+  });
+
+  const parsed = parseMdcmsConfig(config);
+
+  assert.deepEqual(parsed.components, [
+    {
+      name: "Chart",
+      importPath: "@/components/mdx/Chart",
+    },
+  ]);
+});
+```
+
+**Step 2: Run the shared contract test to verify it fails**
+
+Run: `bun test packages/shared/src/lib/contracts/config.test.ts`
+
+Expected: FAIL because `MdcmsComponentRegistration` does not yet allow
+`load` / `loadPropsEditor`.
+
+**Step 3: Write the minimal shared contract changes**
+
+In `packages/shared/src/lib/contracts/config.ts`:
+
+- Extend `MdcmsComponentRegistration` with:
+  - `load?: () => Promise<unknown>`
+  - `loadPropsEditor?: () => Promise<unknown>`
+- Keep `ParsedMdcmsComponentRegistration` serializable and metadata-only.
+- Add a short code comment explaining that runtime loader callbacks are
+  host-local Studio concerns and are intentionally stripped by the shared parser.
+
+**Step 4: Run the shared contract test to verify it passes**
+
+Run: `bun test packages/shared/src/lib/contracts/config.test.ts`
+
+Expected: PASS
+
+**Step 5: Update package docs and commit**
+
+- Document the new runtime-only component loader fields in
+  `packages/shared/README.md`.
+
+```bash
+git add packages/shared/src/lib/contracts/config.ts packages/shared/src/lib/contracts/config.test.ts packages/shared/README.md
+git commit -m "feat: add local mdx component loader fields"
+```
+
+### Task 3: Change the Studio Embed Contract to Accept MDX-Aware Local Config
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/studio.ts`
+- Modify: `packages/studio/src/lib/studio.test.ts`
+- Modify: `packages/studio/README.md`
+- Optional modify: `apps/studio-example/app/admin/[[...path]]/page.tsx`
+- Optional create: `apps/studio-example/app/admin/admin-studio-client.tsx`
+
+**Step 1: Write the failing tests for MDX-aware Studio config**
+
+Add tests in `packages/studio/src/lib/studio.test.ts` that assert:
+
+- `Studio` runtime config accepts raw `SharedMdcmsConfig` with component loader
+  callbacks.
+- `createStudioEmbedConfig(...)` behavior is explicitly documented:
+  - either it remains minimal metadata-only
+  - or it preserves MDX loader fields if you decide to broaden it
+- MDX component registrations are visible to downstream Studio runtime code in a
+  serializable metadata form plus runtime-local loader access.
+
+Suggested minimal test shape:
+
+```ts
+test("createStudioEmbedConfig preserves mdx component metadata needed by Studio", () => {
+  const config = createStudioEmbedConfig({
+    project: "marketing-site",
+    environment: "staging",
+    serverUrl: "http://localhost:4000",
+    components: [
+      {
+        name: "Chart",
+        importPath: "@/components/mdx/Chart",
+        load: async () => null,
+      },
+    ],
+  });
+
+  assert.equal(config.components?.[0]?.name, "Chart");
+});
+```
+
+If the final design is to let `Studio` accept the raw config directly, change
+the assertion to cover the widened `Studio` config type instead.
+
+**Step 2: Run the Studio config test to verify it fails**
+
+Run: `bun test packages/studio/src/lib/studio.test.ts`
+
+Expected: FAIL because the Studio config types currently strip components down
+to `{ project, environment, serverUrl }`.
+
+**Step 3: Implement the minimal Studio config contract**
+
+In `packages/studio/src/lib/studio.ts`:
+
+- Widen the accepted Studio config type so the shell can receive MDX component
+  registrations from `mdcms.config.ts`.
+- Decide one of these two exact implementations and document it in code:
+  - `Studio` accepts raw shared config directly and `createStudioEmbedConfig`
+    becomes optional/minimal; or
+  - `createStudioEmbedConfig` preserves the MDX component registration data
+    needed at runtime.
+
+In `packages/studio/README.md`:
+
+- Replace the server-component-only example with the approved client-side embed
+  pattern for MDX-aware Studio usage.
+- Explain that no backend component sync is required.
+
+**Step 4: Run the Studio config test to verify it passes**
+
+Run: `bun test packages/studio/src/lib/studio.test.ts`
+
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/studio/src/lib/studio.ts packages/studio/src/lib/studio.test.ts packages/studio/README.md apps/studio-example/app/admin/[[...path]]/page.tsx apps/studio-example/app/admin/admin-studio-client.tsx

+- Test/inspect: `packages/studio/src/lib/remote-studio-app.test.ts`
+
+**Step 1: Write the failing tests for local MDX runtime delivery**
+
+Add tests that assert:
+
+- the shell builds an internal runtime capability object from `config.components`
+  without requiring user-authored bridge code
+- the runtime mount context carries MDX catalog metadata needed for insertion UI
+- preview resolution uses the local loader callbacks, not backend data
+
+Suggested loader test shape:
+
+```ts
+test("loadStudioRuntime passes mdx catalog metadata to the mounted runtime", async () => {
+  const contexts: unknown[] = [];
+
+  await loadStudioRuntime({
+    config: {

+  });
+
+  assert.equal((contexts[0] as any).mdx.catalog[0].name, "Chart");

+```
+
+**Step 2: Run the loader/runtime tests to verify they fail**
+
+Run: `bun test packages/studio/src/lib/studio-loader.test.ts packages/studio/src/lib/remote-studio-app.test.ts`
+
+Expected: FAIL because no MDX catalog/runtime capability plumbing exists yet.
+
+**Step 3: Implement the minimal internal resolver**
+
+- Extend the shared shell/runtime contract in
+  `packages/shared/src/lib/contracts/extensibility.ts` with the MDX catalog
+  metadata needed by the mounted runtime.
+- Keep the executable preview/editor resolver internal to `@mdcms/studio`.
+- In `packages/studio/src/lib/studio-component.tsx` and
+  `packages/studio/src/lib/studio-loader.ts`, synthesize the runtime capability
+  object from `config.components`.
+- In `packages/studio/src/lib/remote-studio-app.tsx`, consume local MDX catalog
+  metadata for insertion/edit UI instead of expecting backend data.
+
+**Step 4: Run the loader/runtime tests to verify they pass**
+
+Run: `bun test packages/studio/src/lib/studio-loader.test.ts packages/studio/src/lib/remote-studio-app.test.ts packages/shared/src/lib/contracts/extensibility.test.ts`

+
+**Step 1: Write the failing tests for removing `extractedComponents`**
+
+Update tests so they expect:
+
+- `SchemaRegistrySyncPayload` no longer accepts or documents
+  `extractedComponents`
+- server schema-sync persistence no longer writes that field
+- DB schema contract no longer includes `schema_syncs.extracted_components`
+
+Suggested schema contract test shape:

+});
+```
+
+If the validator reports an unknown-field error differently, assert the real
+path/message shape after updating the validator.
+
+**Step 2: Run the backend/schema tests to verify they fail**
+
+Run: `bun test packages/shared/src/lib/contracts/schema.test.ts apps/server/src/lib/schema-api.test.ts`

+**Step 3: Implement the minimal backend cleanup**
+
+- Remove `extractedComponents` from `SchemaRegistrySyncPayload`.
+- Remove DB schema/storage for `schema_syncs.extractedComponents`.
+- Remove persistence logic and test helpers that seed or assert this field.
+- Update server and CLI README files so they no longer claim component metadata

+# CMS-69 TypeScript Prop Extraction Design
+
+> Local-only planning note. This file is not canonical product documentation and should remain uncommitted.
+
+## Summary
+
+`CMS-69` should establish a stable local prop-extraction contract for MDX
+components without inventing a browser-time reflection system or a required
+manual codegen command.
+
+The embedded Studio must receive plain serializable prop metadata, but the
+source of truth remains the host app's TypeScript component definitions. That
+means extraction belongs on a Node-side integration path in the consumer
+workspace, not in the browser and not on the backend.
+
+## Problem
+
+The current codebase has the first half of the local MDX catalog model from
+`CMS-68`:
+
+- `config.components` is the source of truth.
+- Studio can pass through `extractedProps` if somebody adds them manually.
+- The shared contract still treats `extractedProps` as `Record<string, unknown>`.
+
+What is still missing for `CMS-69`:
+
+- a normative serializable extracted-prop shape
+- deterministic filtering rules for unsupported props
+- a reusable Node-side extractor that can inspect local TypeScript source
+- a supported Studio integration path that prepares config before the client
+  shell renders
+
+Without that, downstream tasks (`CMS-70` through `CMS-74`) would build on an
+unstable pseudo-contract.
+
+## Approved Direction
+
+### Extraction boundary
+
+Prop extraction happens on a Node-side integration path in the consumer
+workspace.
+
+Supported integration points:
+
+- framework server components
+- framework/build hooks
+- dev-server hooks
+- explicit local scripts
+
+Not supported:
+
+- browser-time TypeScript inspection
+- backend-owned component-catalog sync
+- requiring editors to type raw JSON for common props
+
+### Contract ownership
+
+`@mdcms/shared` owns the serializable extracted-prop contract and its runtime
+validation rules.
+
+Planned ownership split:
+
+- `@mdcms/shared`
+  - exported `MdxExtractedProp` / `MdxExtractedProps` contract
+  - strict validation of extracted props inside Studio mount/catalog contracts
+  - a Node-only extractor subpath reusable by Studio and future CLI/tooling
+- `@mdcms/studio/runtime`
+  - a Studio-facing prepare helper that consumes raw config plus workspace
+    context and returns config enriched with `extractedProps`
+- `@mdcms/studio`
+  - continues to consume prepared serializable metadata only
+
+This keeps cross-cutting contract shape in shared while avoiding a future
+dependency from CLI tooling onto the Studio package.
+
+### Supported normalized shapes
+
+The extracted metadata should stay intentionally small and fail closed:
+
+- `string`
+- `number`
+- `boolean`
+- `date`
+- string-literal `enum`
+- `array` of `string` or `number`
+- `json` only when the developer explicitly opts the prop into a JSON editor
+  and the TypeScript shape is JSON-serializable
+- `rich-text` for `children` / `ReactNode`
+
+Requiredness is derived from declared TypeScript optionality only. The
+extractor does not inspect runtime default expressions in component bodies.
+
+### Unsupported-by-default shapes
+
+Unsupported props are omitted from `extractedProps` and hidden from the
+auto-generated Studio form:
+
+- functions and callbacks
+- refs
+- React elements/components other than `children`
+- object/record/map/set/tuple/class-instance shapes without explicit `json`
+  opt-in
+- mixed unions, intersections, unresolved generics
+- arrays whose item type is not exactly `string` or `number`
+- anything not JSON-serializable or not deterministically normalizable
+
+This keeps the contract safe and stable for `CMS-70` form mapping.
+
+### Integration model
+
+The preferred host-app flow is:
+
+1. import authored `mdcms.config.ts` on the Node side
+2. call a prepare helper that resolves component source files and extracts prop
+   metadata
+3. pass the prepared config into the client `<Studio />` shell
+
+This means the existing direct-client-import story remains acceptable for
+preview-only MDX registration, but auto-generated props editing depends on the
+prepared config path.
+
+## Consequences
+
+### Benefits
+
+- No backend coupling for MDX component metadata.
+- No required manual codegen command.
+- Stable serializable contract for downstream form/editor tasks.
+- One extractor implementation reusable by multiple local consumers.
+
+### Tradeoffs
+
+- The prepared-config path is more explicit than "just import config in a client
+  component."
+- The extractor needs TypeScript compiler access and filesystem access on the
+  Node side.
+- A new shared node-only export surface is needed so Studio and future CLI
+  flows can reuse the same extractor without depending on each other.
+
+## Spec Delta Applied
+
+The owning spec updates for this design are now in:
+
+- `docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
+- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+
+Those edits:
+
+- replace the old CLI-only extraction phrasing with a Node-side preparation
+  pipeline
+- define the normalized `MdxExtractedProp` contract
+- define fail-closed unsupported-prop filtering rules
+- clarify that browser runtime never performs TypeScript inspection
+
+## Acceptance Mapping
+
+- "Extracted schema hides functions/refs and complex unsupported props" maps to
+  the fail-closed normalization rules plus fixture coverage.
+- "Prop extraction output is stable across local MDX component-catalog
+  consumers" maps to shared contract types plus a reusable node-only extractor.
+- "Foundational behavior is documented and reusable" maps to spec deltas,
+  shared runtime validation, and runtime/helper README updates.

+# CMS-69 TypeScript Prop Extraction Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add a deterministic Node-side MDX prop extraction pipeline that turns local TypeScript component props into stable serializable `extractedProps` metadata for Studio while filtering unsupported shapes by contract.
+
+**Architecture:** The canonical specs now define `extractedProps` as a shared serializable contract owned by `@mdcms/shared`. Implement that contract and validator in shared, add a node-only shared extractor subpath backed by the TypeScript compiler API, expose a Studio-facing prepare helper from `@mdcms/studio/runtime`, and update the Studio example/docs to pass prepared config into the client shell instead of assuming browser-time prop introspection.
+
+**Tech Stack:** Bun, Nx, TypeScript compiler API, React, node:test, Zod, Markdown specs/READMEs
+
+---
+
+### Task 1: Lock the Shared Extracted-Prop Contract
+
+**Files:**
+
+- Modify: `packages/shared/src/lib/contracts/extensibility.ts`
+- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
+- Modify: `packages/shared/README.md`
+
+**Step 1: Write the failing contract tests**
+
+Add tests in `packages/shared/src/lib/contracts/extensibility.test.ts` that
+assert:
+
+- `assertStudioMountContext(...)` accepts MDX catalog entries whose
+  `extractedProps` values use only the allowed variants:
+  - `{ type: "string", required: false }`
+  - `{ type: "enum", required: true, values: ["bar", "line"] }`
+  - `{ type: "array", required: true, items: "number" }`
+  - `{ type: "json", required: false }`
+  - `{ type: "rich-text", required: false }`
+- invalid extracted-prop payloads are rejected:
+  - unknown `type`
+  - `array.items = "boolean"`
+  - enum with empty `values`
+  - extra keys on prop descriptors
+
+Example accepted shape:
+
+```ts
+assert.doesNotThrow(() =>
+  assertStudioMountContext({
+    apiBaseUrl: "http://localhost:4000",
+    basePath: "/admin",
+    auth: { mode: "cookie" },
+    hostBridge: validHostBridge,
+    mdx: {
+      catalog: {
+        components: [
+          {
+            name: "Chart",
+            importPath: "@/components/mdx/Chart",
+            extractedProps: {
+              title: { type: "string", required: false },
+              type: {
+                type: "enum",
+                required: true,
+                values: ["bar", "line"],
+              },
+            },
+          },
+        ],
+      },
+      resolvePropsEditor: () => null,
+    },
+  }),
+);
+```
+
+**Step 2: Run the shared contract test to verify it fails**
+
+Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
+
+Expected: FAIL because `extractedProps` is still validated as
+`Record<string, unknown>`.
+
+**Step 3: Implement the shared contract**
+
+In `packages/shared/src/lib/contracts/extensibility.ts`:
+
+- export:
+  - `MdxExtractedProp`
+  - `MdxExtractedProps`
+- replace the permissive `extractedProps: z.record(z.string(), z.unknown())`
+  with a strict schema for the approved variants
+- make enum descriptors reject empty `values`
+- keep the shape strict so unsupported keys fail validation
+
+In `packages/shared/README.md`:
+
+- document the extracted-prop variants and the purpose of the contract
+
+**Step 4: Run the shared contract test to verify it passes**
+
+Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
+
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/shared/src/lib/contracts/extensibility.ts packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/README.md
+git commit -m "feat(shared): define mdx extracted prop contract"
+```
+
+### Task 2: Build the Node-Only Shared TypeScript Extractor
+
+**Files:**
+
+- Create: `packages/shared/src/lib/mdx/extracted-props.ts`
+- Create: `packages/shared/src/lib/mdx/extracted-props.test.ts`
+- Create: `packages/shared/src/lib/mdx/index.ts`
+- Modify: `packages/shared/package.json`
+- Modify: `packages/shared/README.md`
+
+**Step 1: Write the failing extractor fixture tests**
+
+Add fixture-driven tests in `packages/shared/src/lib/mdx/extracted-props.test.ts`
+that create temporary `.tsx` files and assert:
+
+- supported props extract correctly:
+  - `title?: string`
+  - `count: number`
+  - `published: boolean`
+  - `type: "bar" | "line"`
+  - `data: number[]`
+  - `tags?: string[]`
+  - `children?: ReactNode`
+- unsupported props are omitted:
+  - `onClick?: () => void`
+  - `forwardedRef?: Ref<HTMLDivElement>`
+  - `options: Record<string, string>`
+  - `pair: [number, number]`
+- `json` hint opt-in re-enables a JSON-serializable object shape:
+  - `options: { theme: string; compact: boolean }` plus
+    `propHints.options = { widget: "json" }` =>
+    `{ type: "json", required: true }`
+- non-serializable `json` opt-in still fails closed:
+  - `handlerMap: Record<string, () => void>` stays omitted even with `json`
+- requiredness follows declared TypeScript only:
+  - `title?: string` => `required: false`
+  - `title: string | undefined` => `required: false`
+  - destructuring default values do not change the extracted `required` flag
+
+Example expected output:
+
+```ts
+assert.deepEqual(result, {
+  title: { type: "string", required: false },
+  type: { type: "enum", required: true, values: ["bar", "line"] },
+  data: { type: "array", required: true, items: "number" },
+});
+```
+
+**Step 2: Run the extractor test to verify it fails**
+
+Run: `bun test packages/shared/src/lib/mdx/extracted-props.test.ts`
+
+Expected: FAIL because the extractor module does not exist yet.
+
+**Step 3: Implement the extractor**
+
+In `packages/shared/src/lib/mdx/extracted-props.ts`:
+
+- use the TypeScript compiler API to:
+  - create/load a `Program`
+  - resolve the component source file from an absolute path
+  - find the exported component symbol
+  - resolve its props type from function params or a declared props interface
+- expose a narrow API such as:
+
+```ts
+export function extractMdxComponentProps(input: {
+  filePath: string;
+  componentName: string;
+  propHints?: Record<string, unknown>;
+  tsconfigPath?: string;
+}): MdxExtractedProps;
+```
+
+- normalize only the supported shapes
+- omit everything else
+- treat `json` opt-in as allowed only for JSON-serializable shapes
+- add short comments only around the non-obvious TypeScript symbol/type walking
+
+In `packages/shared/src/lib/mdx/index.ts`:
+
+- re-export the extractor API
+
+In `packages/shared/package.json`:
+
+- add a node-oriented export such as `./mdx`
+- add `typescript` as a package dependency if the extractor imports it at runtime
+
+In `packages/shared/README.md`:
+
+- document the node-only extractor subpath briefly
+
+**Step 4: Run the extractor and contract tests**
+
+Run: `bun test packages/shared/src/lib/mdx/extracted-props.test.ts packages/shared/src/lib/contracts/extensibility.test.ts`
+
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/shared/src/lib/mdx/extracted-props.ts packages/shared/src/lib/mdx/extracted-props.test.ts packages/shared/src/lib/mdx/index.ts packages/shared/package.json packages/shared/README.md
+git commit -m "feat(shared): add mdx prop extraction helper"
+```
+
+### Task 3: Add a Studio Runtime Prepare Helper and Typed Consumption Path
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/studio.ts`
+- Modify: `packages/studio/src/lib/studio.test.ts`
+- Modify: `packages/studio/src/lib/studio-loader.ts`
+- Modify: `packages/studio/src/lib/studio-loader.test.ts`
+- Modify: `packages/studio/README.md`
+
+**Step 1: Write the failing Studio tests**
+
+Add tests that assert:
+
+- `@mdcms/studio/runtime` exposes a prepare helper that enriches component
+  entries with typed `extractedProps`
+- the prepare helper accepts authored config plus workspace context
+- `loadStudioRuntime(...)` reads typed `extractedProps` without the current
+  `as { extractedProps?: unknown }` escape hatch
+
+Suggested test shape in `packages/studio/src/lib/studio.test.ts`:
+
+```ts
+test("prepareStudioConfig enriches mdx component metadata from source files", async () => {
+  const config = await prepareStudioConfig(
+    {
+      project: "marketing-site",
+      environment: "staging",
+      serverUrl: "http://localhost:4000",
+      components: [
+        {
+          name: "Chart",
+          importPath: "@/components/mdx/Chart",
+        },
+      ],
+    },
+    {
+      cwd: fixtureDir,
+      resolveImportPath: (value) =>
+        value === "@/components/mdx/Chart"
+          ? join(fixtureDir, "Chart.tsx")
+          : value,
+    },
+  );
+
+  assert.deepEqual(config.components?.[0]?.extractedProps, {
+    title: { type: "string", required: false },
+  });
+});
+```
+
+And in `packages/studio/src/lib/studio-loader.test.ts`:
+
+- remove the cast-based fake component shape and assert the loader accepts the
+  prepared typed config directly
+
+**Step 2: Run the Studio tests to verify they fail**
+
+Run: `bun test packages/studio/src/lib/studio.test.ts packages/studio/src/lib/studio-loader.test.ts`
+
+Expected: FAIL because there is no prepare helper and the config types do not
+carry extracted props explicitly.
+
+**Step 3: Implement the Studio prepare helper and loader typing**
+
+In `packages/studio/src/lib/studio.ts`:
+
+- add a server-safe helper such as:
+
+```ts
+export async function prepareStudioConfig(
+  config: SharedMdcmsConfig,
+  options: {
+    cwd: string;
+    resolveImportPath?: (value: string) => string;
+    tsconfigPath?: string;
+  },
+): Promise<MdcmsConfig>;
+```
+
+- internally call the shared node-only extractor for each component entry
+- preserve authored loader callbacks and other config metadata
+- require/validate `environment` before returning the prepared config
+
+In `packages/studio/src/lib/studio-loader.ts`:
+
+- replace the untyped `readExtractedProps(...)` cast with direct typed access
+- keep the runtime consuming only serializable metadata plus local executable
+  resolvers
+
+In `packages/studio/README.md`:
+
+- update the MDX-aware embed example to show:
+  - server-side `prepareStudioConfig(...)`
+  - client-side `<Studio config={preparedConfig} ... />`
+- keep the plain runtime-helper story accurate
+
+**Step 4: Run the Studio tests to verify they pass**
+
+Run: `bun test packages/studio/src/lib/studio.test.ts packages/studio/src/lib/studio-loader.test.ts`
+
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/studio/src/lib/studio.ts packages/studio/src/lib/studio.test.ts packages/studio/src/lib/studio-loader.ts packages/studio/src/lib/studio-loader.test.ts packages/studio/README.md
+git commit -m "feat(studio): prepare mdx component props locally"
+```
+
+### Task 4: Wire the Example App and Run Verification
+
+**Files:**
+
+- Modify: `apps/studio-example/app/admin/[[...path]]/page.tsx`
+- Optional create: `apps/studio-example/app/admin/admin-studio-client.tsx`
+- Optional modify: `apps/studio-example/mdcms.config.ts`
+- Reference: `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+- Reference: `docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
+
+**Step 1: Write the failing example integration assertion**
+
+Add or update a lightweight test/contract assertion that the example app can:
+
+- load raw authored config on the server side
+- prepare it before passing it to the client `Studio` shell
+
+If there is no dedicated example test yet, add a type-level assertion in
+`packages/studio/src/lib/studio.test.ts` or a focused smoke check in the example
+route source.
+
+**Step 2: Run the relevant Studio/example tests to verify they fail**
+
+Run: `bun test packages/studio/src/lib/studio.test.ts`
+
+Expected: FAIL until the example/docs use the new helper path consistently.
+
+**Step 3: Update the example integration**
+
+In the example app:
+
+- keep the route itself server-side
+- call `prepareStudioConfig(...)`
+- pass the result into a small client wrapper that renders `<Studio />`
+
+Keep the example minimal; it only needs to demonstrate the supported host-app
+integration boundary.
+
+**Step 4: Run targeted verification**
+
+Run:
+
+```bash
+bun test packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/src/lib/mdx/extracted-props.test.ts
+bun test packages/studio/src/lib/studio.test.ts packages/studio/src/lib/studio-loader.test.ts
+bun run format:check
+bun run check
+```
+
+Expected:
+
+- all targeted shared/studio tests PASS
+- `bun run format:check` PASS
+- `bun run check` PASS
+
+**Step 5: Commit**
+
+```bash
+git add apps/studio-example/app/admin/[[...path]]/page.tsx apps/studio-example/app/admin/admin-studio-client.tsx apps/studio-example/mdcms.config.ts

+# CMS-70 Prop Type to Form Control Mapping Design
+
+> Local-only planning note. This file is not canonical product documentation and should remain uncommitted.
+
+## Summary
+
+`CMS-70` should turn the extracted local MDX prop metadata from `CMS-69` into a
+stable auto-form contract that downstream Studio/editor tasks can reuse without
+re-deriving UI decisions ad hoc.
+
+The main contract wrinkle is the URL case. The approved direction is to model
+URL as string formatting metadata, not as a new widget override. That keeps
+type extraction, default form mapping, and later widget overrides clearly
+separated.
+
+## Problem
+
+The codebase already has:
+
+- local MDX component catalog transport from host app to embedded Studio
+- deterministic TypeScript prop extraction in `@mdcms/shared`
+- fail-closed omission of unsupported props
+- a basic Studio distinction between "auto form available" and "custom props
+  editor available"
+
+What is still missing for `CMS-70`:
+
+- a shared, explicit prop-to-control mapping contract
+- a deterministic URL-input signal for string props
+- a reusable mapping helper instead of Studio-only branching
+- proof that Studio consumes the shared mapping contract rather than only
+  checking whether `extractedProps` exists
+
+Without that, `CMS-71` and `CMS-72` would have to infer control semantics from
+raw extracted prop metadata in multiple places.
+
+## Approved Direction
+
+### Contract boundary
+
+`@mdcms/shared` owns both:
+
+- the extracted MDX prop contract
+- the pure auto-form mapping helper derived from that contract
+
+`@mdcms/studio` consumes the mapping output but does not own the mapping rules.
+
+### URL handling
+
+URL is modeled as an optional format on string props:
+
+- extracted prop shape: `{ type: "string", required: boolean, format?: "url" }`
+- declaration source: `propHints.<propName>.format = "url"`
+- extraction rule: preserve the format only when the normalized prop type is
+  `string`
+
+This is intentionally not a widget. Widget overrides remain the later `CMS-71`
+concern.
+
+### Shared auto-form output
+
+Introduce a pure shared mapper that turns `MdxExtractedProps` into explicit
+auto-form field metadata. Planned default control kinds:
+
+- `string` -> `text`
+- `string` with `format: "url"` -> `url`
+- `number` -> `number`
+- `boolean` -> `boolean`
+- `enum` -> `select`
+- `array` with `items: "string"` -> `string-list`
+- `array` with `items: "number"` -> `number-list`
+- `date` -> `date`
+- `rich-text` -> `rich-text`
+
+Function and ref props remain hidden by omission upstream in extraction, which
+already matches the spec.
+
+### Studio integration scope
+
+`CMS-70` should stop short of building the full editable props UI. The Studio
+side only needs a thin proof consumer that uses the shared mapper in the
+existing hidden diagnostics/runtime test path.
+
+That keeps this task foundational and avoids bleeding into `CMS-72`.
+
+## Consequences
+
+### Benefits
+
+- One mapping source of truth for Studio and future local tooling.
+- URL inputs become deterministic without expanding the widget system early.
+- Downstream tasks can build form rendering on explicit field metadata instead
+  of reinterpreting extracted props.
+
+### Tradeoffs
+
+- The extracted prop contract grows slightly to include string formatting.
+- Shared code now owns one more MDX helper surface that needs tests and README
+  coverage.
+- The product spec must explicitly define the URL format hint before
+  implementation.
+
+## Spec Delta Required
+
+The owning spec update belongs in:
+
+- `docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
+
+Required contract delta:
+
+- define URL intent as `propHints.<propName>.format = "url"`
+- define extracted string props as optionally carrying `format: "url"`
+- define Studio mapping of `{ type: "string", format: "url" }` to a URL input
+  with validation
+- keep widget overrides limited to the existing widget list
+
+## Acceptance Mapping
+
+- "Auto-controls implement all 11 prop-type-to-form-control mappings" maps to
+  the shared mapping helper plus tests covering each supported control outcome.
+- "Foundational behavior is documented and reusable" maps to the spec delta,
+  shared contract typing, shared mapping helper exports, and README notes.
+- "Any newly introduced public contract ... is documented at the point of use"
+  maps to contract comments/README updates in the shared package.

+# CMS-70 Prop Type to Form Control Mapping Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add a shared, deterministic MDX prop-to-form-control mapping layer that converts extracted local component prop metadata into reusable auto-form field definitions, including URL-formatted string handling, while keeping widget overrides out of scope for this task.
+
+**Architecture:** Apply the missing product contract first in `SPEC-007`, then extend the shared extracted-prop contract so string props can carry `format: "url"`. Build a pure shared mapping helper in `@mdcms/shared/mdx` that turns extracted props into explicit auto-form fields for the CMS-70 mappings only, and have Studio consume that helper in its diagnostics/test surface instead of treating any non-empty `extractedProps` object as an auto-form signal.
+
+**Tech Stack:** Bun, Nx, TypeScript, node:test, Zod, React, Markdown specs/READMEs
+
+---
+
+### Task 1: Apply the Owning Spec Delta
+
+**Files:**
+
+- Modify: `docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
+
+**Step 1: Update the spec prose before code**
+
+Edit `docs/specs/SPEC-007-editor-mdx-and-collaboration.md` so it explicitly
+defines:
+
+- `propHints.<propName>.format = "url"` as the URL intent signal
+- `MdxExtractedProp` string descriptors may carry optional `format: "url"`
+- `{ type: "string", format: "url" }` maps to a URL input with validation
+- this is not a widget and does not expand the widget list in the later
+  override section
+
+Suggested contract snippet:
+
+```ts
+export type MdxExtractedProp =
+  | { type: "string"; required: boolean; format?: "url" }
+  | { type: "number"; required: boolean }
+  | { type: "boolean"; required: boolean }
+  | { type: "date"; required: boolean }
+  | { type: "enum"; required: boolean; values: string[] }
+  | { type: "array"; required: boolean; items: "string" | "number" }
+  | { type: "json"; required: boolean }
+  | { type: "rich-text"; required: boolean };
+```
+
+**Step 2: Verify the spec wording matches the approved direction**
+
+Run: `rg -n "format: \"url\"|URL input with validation|not a widget" docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
+
+Expected: the owning spec now contains all three concepts.
+
+**Step 3: Commit**
+
+```bash
+git add docs/specs/SPEC-007-editor-mdx-and-collaboration.md
+git commit -m "docs(specs): clarify mdx url format mapping"
+```
+
+### Task 2: Extend the Shared Extracted-Prop Contract
+
+**Files:**
+
+- Modify: `packages/shared/src/lib/contracts/extensibility.ts`
+- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
+- Modify: `packages/shared/README.md`
+
+**Step 1: Write the failing contract tests**
+
+Add tests in `packages/shared/src/lib/contracts/extensibility.test.ts` that
+assert:
+
+- a string descriptor with `format: "url"` is accepted
+- non-string descriptors with `format: "url"` are rejected
+- unsupported format values are rejected
+- existing valid descriptors still pass unchanged
+
+Example accepted payload:
+
+```ts
+extractedProps: {
+  website: {
+    type: "string",
+    required: false,
+    format: "url",
+  },
+}
+```
+
+Example rejected payloads:
+
+```ts
+extractedProps: {
+  publishedAt: {
+    type: "date",
+    required: false,
+    format: "url",
+  },
+}
+```
+
+```ts
+extractedProps: {
+  title: {
+    type: "string",
+    required: true,
+    format: "email",
+  },
+}
+```
+
+**Step 2: Run the contract test to verify it fails**
+
+Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
+
+Expected: FAIL because the validator does not permit `format` on string props
+yet.
+
+**Step 3: Implement the contract change**
+
+In `packages/shared/src/lib/contracts/extensibility.ts`:
+
+- extend the `MdxExtractedProp` TypeScript union so only string props can carry
+  optional `format: "url"`
+- update the Zod schema for extracted props to mirror that shape strictly
+- keep all descriptor objects strict so extra keys still fail validation
+
+In `packages/shared/README.md`:
+
+- document the string `format: "url"` option and clarify that it drives default
+  auto-form behavior rather than the widget override system
+
+**Step 4: Run the contract test to verify it passes**
+
+Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
+
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/shared/src/lib/contracts/extensibility.ts packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/README.md
+git commit -m "feat(shared): add mdx string format metadata"
+```
+
+### Task 3: Preserve URL Format During Prop Extraction
+
+**Files:**
+
+- Modify: `packages/shared/src/lib/mdx/extracted-props.ts`
+- Modify: `packages/shared/src/lib/mdx/extracted-props.test.ts`
+
+**Step 1: Write the failing extraction tests**
+
+Add tests in `packages/shared/src/lib/mdx/extracted-props.test.ts` that cover:
+
+- `string` prop plus `propHints.website = { format: "url" }` extracts as
+  `{ type: "string", required: ..., format: "url" }`
+- the same hint on `number`, `date`, `enum`, `array`, or `rich-text` is ignored
+- unsupported hint values do not leak into extracted output
+
+Example fixture:
+
+```tsx
+export interface LinkCardProps {
+  title: string;
+  website?: string;
+}
+
+export function LinkCard(_props: LinkCardProps) {
+  return null;
+}
+```
+
+Example expected output:
+
+```ts
+{
+  title: { type: "string", required: true },
+  website: { type: "string", required: false, format: "url" },
+}
+```
+
+**Step 2: Run the extractor test to verify it fails**
+
+Run: `bun test packages/shared/src/lib/mdx/extracted-props.test.ts`
+
+Expected: FAIL because extracted string props do not preserve `format` yet.
+
+**Step 3: Implement the extraction logic**
+
+In `packages/shared/src/lib/mdx/extracted-props.ts`:
+
+- add a narrow helper such as `getStringFormat(propHint)` that returns `"url"`
+  only when:
+  - the hint is an object
+  - `format === "url"`
+- apply that helper only inside the `string` normalization branch
+- ignore `format` hints for all non-string normalized prop shapes
+
+Keep the function fail-closed. Invalid or irrelevant hints should not throw and
+should not alter the extracted descriptor.
+
+**Step 4: Run the extractor and contract tests**
+
+Run: `bun test packages/shared/src/lib/mdx/extracted-props.test.ts packages/shared/src/lib/contracts/extensibility.test.ts`
+
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/shared/src/lib/mdx/extracted-props.ts packages/shared/src/lib/mdx/extracted-props.test.ts
+git commit -m "feat(shared): preserve mdx url string hints"
+```
+
+### Task 4: Add the Shared Auto-Form Mapping Helper
+
+**Files:**
+
+- Create: `packages/shared/src/lib/mdx/auto-form.ts`
+- Create: `packages/shared/src/lib/mdx/auto-form.test.ts`
+- Modify: `packages/shared/src/lib/mdx/index.ts`
+- Modify: `packages/shared/README.md`
+
+**Step 1: Write the failing mapping tests**
+
+Create `packages/shared/src/lib/mdx/auto-form.test.ts` with coverage for all
+CMS-70 mappings:
+
+- `string` -> `text`
+- `string` + `format: "url"` -> `url`
+- `number` -> `number`
+- `boolean` -> `boolean`
+- `enum` -> `select`
+- `array:string` -> `string-list`
+- `array:number` -> `number-list`
+- `date` -> `date`
+- `rich-text` -> `rich-text`
+
+Also assert:
+
+- field output is deterministic and preserves input property iteration order
+- `json` extracted props are omitted for now
+- empty input returns `[]`
+
+Suggested public shape:
+
+```ts
+type MdxAutoFormField =
+  | { name: string; control: "text"; required: boolean }
+  | { name: string; control: "url"; required: boolean }
+  | { name: string; control: "number"; required: boolean }
+  | { name: string; control: "boolean"; required: boolean }
+  | { name: string; control: "select"; required: boolean; options: string[] }
+  | { name: string; control: "string-list"; required: boolean }
+  | { name: string; control: "number-list"; required: boolean }
+  | { name: string; control: "date"; required: boolean }
+  | { name: string; control: "rich-text"; required: boolean };
+```
+
+**Step 2: Run the mapping test to verify it fails**
+
+Run: `bun test packages/shared/src/lib/mdx/auto-form.test.ts`
+
+Expected: FAIL because the helper module does not exist yet.
+
+**Step 3: Implement the mapping helper**
+
+In `packages/shared/src/lib/mdx/auto-form.ts`:
+
+- export the `MdxAutoFormField` type
+- export a pure function such as:
+
+```ts
+export function createMdxAutoFormFields(
+  extractedProps: MdxExtractedProps | undefined,
+): MdxAutoFormField[];
+```
+
+- switch on each extracted prop variant and return the mapped control
+- skip `json` props for this task so CMS-71 can own the widget override path
+- preserve deterministic order by iterating `Object.entries(extractedProps)`
+
+In `packages/shared/src/lib/mdx/index.ts`:
+
+- export the new helper/types
+
+In `packages/shared/README.md`:
+
+- add a short section describing `createMdxAutoFormFields(...)` and the default
+  controls it emits
+
+**Step 4: Run the shared MDX tests**
+
+Run: `bun test packages/shared/src/lib/mdx/extracted-props.test.ts packages/shared/src/lib/mdx/auto-form.test.ts`
+
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/shared/src/lib/mdx/auto-form.ts packages/shared/src/lib/mdx/auto-form.test.ts packages/shared/src/lib/mdx/index.ts packages/shared/README.md
+git commit -m "feat(shared): add mdx auto form mapping"
+```
+
+### Task 5: Wire the Shared Mapper into Studio Diagnostics
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/remote-studio-app.tsx`
+- Modify: `packages/studio/src/lib/remote-studio-app.test.ts`
+
+**Step 1: Write the failing Studio test**
+
+Update `packages/studio/src/lib/remote-studio-app.test.ts` so the document-route
+diagnostics assert explicit mapped control metadata rather than only the
+presence of `extractedProps`.
+
+For example, expect rendered markers such as:
+
+```html
+<span data-mdcms-mdx-auto-form="Chart">Auto form</span>
+<span data-mdcms-mdx-auto-control="Chart:title:text"></span>
+<span data-mdcms-mdx-auto-control="Chart:website:url"></span>
+```
+
+Also add a component whose extracted props contain only `json` and assert it
+does not render the auto-form marker yet.
+
+**Step 2: Run the Studio test to verify it fails**
+
+Run: `bun test packages/studio/src/lib/remote-studio-app.test.ts`
+
+Expected: FAIL because the runtime currently treats any non-empty
+`extractedProps` object as an auto-form signal.
+
+**Step 3: Implement the Studio consumer**
+
+In `packages/studio/src/lib/remote-studio-app.tsx`:
+
+- import `createMdxAutoFormFields` from `@mdcms/shared/mdx`
+- replace `hasGeneratedPropsEditor(...)` with a helper that builds mapped fields
+  and checks `fields.length > 0`
+- expose the mapped control kinds on the hidden diagnostics surface so the test
+  can prove Studio is using the shared mapping contract
+
+Keep this diagnostic-only. Do not build the full props form UI in this task.
+
+**Step 4: Run the Studio test to verify it passes**
+
+Run: `bun test packages/studio/src/lib/remote-studio-app.test.ts`
+
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/studio/src/lib/remote-studio-app.tsx packages/studio/src/lib/remote-studio-app.test.ts
+git commit -m "feat(studio): consume mdx auto form mappings"
+```
+
+### Task 6: Run End-to-End Verification
+
+**Files:**
+
+- Modify: none
+
+**Step 1: Run focused package tests**
+
+Run:
+
+```bash
+bun test packages/shared/src/lib/contracts/extensibility.test.ts
+bun test packages/shared/src/lib/mdx/extracted-props.test.ts
+bun test packages/shared/src/lib/mdx/auto-form.test.ts
+bun test packages/studio/src/lib/remote-studio-app.test.ts
+```
+
+Expected: all PASS
+
+**Step 2: Run workspace formatting check**
+
+Run: `bun run format:check`
+
+Expected: PASS
+
+**Step 3: Run workspace baseline check**
+
+Run: `bun run check`
+
+Expected: PASS
+
+**Step 4: Inspect git status**
+
+Run: `git status --short`
+
+Expected:
+
+- only CMS-70 code/spec files are staged or modified
+- local-only files remain unstaged and uncommitted:
+  - `AGENTS.md`
+  - `ROADMAP_TASKS.md`
+  - `docs/plans/`
+
+**Step 5: Final commit**
+
+```bash

+# Studio UI Runtime Mock Integration Design
+
+Date: 2026-03-25
+Task: CMS-47 + CMS-48 follow-on Studio UI integration
+
+## Goal
+
+Replace the current remote Studio placeholder UI with the approved `./studio_ui` admin mock inside the real `@mdcms/studio` runtime so visiting `/admin` in the host app renders the new Studio shell and route set through the existing bootstrap/runtime-delivery path.
+
+## Canonical Inputs
+
+- `ROADMAP_TASKS.md` CMS-47, CMS-48, CMS-49, CMS-50
+- `docs/specs/README.md`
+- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+- `packages/studio/README.md`
+- `packages/studio/src/lib/build-runtime.ts`
+- `packages/studio/src/lib/remote-module.ts`
+- `packages/studio/src/lib/remote-studio-app.tsx`
+- `packages/studio/src/lib/remote-studio-app.test.ts`
+- `apps/studio-example/app/admin/[[...path]]/page.tsx`
+- `apps/studio-example/README.md`
+- `studio_ui/`
+
+## Spec Delta
+
+`SPEC-006` already owns the Studio embed shell and these runtime routes:
+
+- `/admin`
+- `/admin/content`
+- `/admin/content/:type`
+- `/admin/content/:type/:documentId`
+- `/admin/environments`
+- `/admin/users`
+- `/admin/settings`
+- `/admin/trash`
+
+The approved mock adds runtime-owned admin pages that are not yet specified in
+the owning spec:
+
+- `/admin/media`
+- `/admin/schema`
+- `/admin/workflows`
+- `/admin/api`
+
+The required spec delta is narrow:
+
+- add those four routes to `SPEC-006` as Studio runtime-owned navigable
+  surfaces
+- define this phase as shell-only/mock rendering for those pages
+- keep live backend contracts and mutations for those pages deferred to their
+  future owning work
+- explicitly keep mock auth pages out of scope because Studio auth remains
+  governed by `SPEC-005` and the host embed flow in `SPEC-006`
+
+## Scope
+
+### In Scope
+
+- Port the admin mock route set into `packages/studio`
+- Keep the existing bootstrap, verification, and remote-module mount flow
+- Replace Next-specific routing helpers with runtime-local navigation helpers
+- Add a runtime-owned styling path so the remote bundle renders independently of
+  host-app CSS
+- Keep mock data, stub actions, and local-only state where backend wiring is not
+  part of this slice
+- Update tests so `/admin/*` routes are asserted through the real remote runtime
+
+### Out of Scope
+
+- Wiring mock pages to live backend contracts beyond what already exists
+- Reworking the host-app embed architecture in `apps/studio-example`
+- Porting `(auth)` pages from `studio_ui`
+- Making `/admin/media`, `/admin/schema`, `/admin/workflows`, or `/admin/api`
+  functional beyond the approved shell-only placeholders
+- Introducing new server endpoints or mutation contracts for the placeholder
+  pages
+
+## Design Decisions
+
+### 1. Keep the Real Runtime Boundary Intact
+
+The host app should keep mounting `@mdcms/studio` at `/admin/*` through the
+existing catch-all route. The visible UI change should come from updating the
+remote runtime bundle in `packages/studio`, not from bypassing the runtime and
+rendering the mock directly in `apps/studio-example`.
+
+This preserves the architecture already defined in `SPEC-006`:
+
+- shell fetches bootstrap
+- shell verifies runtime
+- shell loads remote module
+- remote runtime owns the Studio UI after `mount(...)`
+
+### 2. Port Only the Admin Runtime Surfaces
+
+The `studio_ui` project contains both admin and auth pages. Only the admin route
+set should move into the remote runtime. Auth remains outside the Studio runtime
+surface and should continue to be owned by the host/server auth stack.
+
+### 3. Replace Next Router APIs With Runtime-Local Navigation
+
+The mock currently depends on:
+
+- `next/link`
+- `next/navigation`
+- `next/font`
+
+The runtime port should replace those with:
+
+- a base-path-aware link component that uses `history.pushState`
+- pathname/params helpers backed by the remote runtime router state
+- plain CSS font stacks instead of Next font loaders
+
+This keeps the runtime bundle framework-agnostic once it is mounted.
+
+### 4. Add a Runtime-Owned CSS Asset Path
+
+The current remote runtime uses inline styles, while the mock uses Tailwind v4
+utility classes and a global token sheet.
+
+The port should add a dedicated runtime styling path:
+
+- keep the mock's token system and visual language
+- compile the runtime stylesheet as a Studio asset during `build-runtime`
+- derive the stylesheet URL from the remote module URL so the mounted runtime
+  can install its own styles without host-app participation
+
+This avoids coupling the Studio UI to host-app Tailwind configuration.
+
+### 5. Port Selectively, Not Blindly
+
+Only the components actually needed by the approved route set should move into
+`packages/studio`:
+
+- shared admin layout
+- sidebar/header/shell state
+- mock data and view helpers
+- route page components
+- only the shadcn/Radix primitives used by those pages
+- editor components needed for the document route
+
+This keeps the first integration pass focused while still delivering the whole
+approved route set.
+
+### 6. Keep Backend Wiring Deferred But Shape the Runtime for It
+
+Mock data is acceptable in this phase, but the port should keep clean seams for
+future backend work:
+
+- route-level page components should accept data via small local selectors or
+  adapters rather than reading globals everywhere
+- extra placeholder pages should remain obvious shell surfaces, not pretend to
+  be wired features
+- role visibility rules should already exist for admin-only surfaces so later
+  real auth/session wiring can slot into the same structure
+
+## Verification
+
+Completion should be backed by:
+
+- spec/doc updates for the extra Studio pages
+- runtime build tests covering emitted CSS assets
+- remote runtime tests covering:
+  - route matching for the expanded `/admin/*` set
+  - local navigation helpers
+  - route rendering titles for the ported pages
+  - role-aware nav visibility where applicable
+- loader tests proving bootstrap/mount behavior remains unchanged
+- host smoke verification so `http://127.0.0.1:4173/admin` renders the new UI
+- `bun run format:check`
+- `bun run check`
+
+## Notes
+
+- `docs/plans/` is local-only in this repository and must remain untracked.
+- The current repository layout uses `packages/studio`, not `apps/studio`, so
+  implementation should follow the actual workspace boundaries.
+- `ROADMAP_TASKS.md` and `SPEC-006` are aligned for the existing route set, but
+  the extra mock pages need the spec patch before implementation starts.

+# Studio UI Runtime Mock Integration Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Port the approved `studio_ui` admin mock into the real `@mdcms/studio` remote runtime so `/admin/*` in the host app renders the new Studio UI through the existing bootstrap/runtime path.
+
+**Architecture:** Keep the current `@mdcms/studio` shell, bootstrap verification, and remote module loading intact. Update the owning spec first for the extra mock-only admin pages, then add a runtime-owned CSS asset path, base-path-aware navigation helpers, and a selective port of the admin shell/pages into `packages/studio` with mock data preserved for now.
+
+**Tech Stack:** Bun, TypeScript, React 19, Next host app, Tailwind v4 runtime stylesheet build, Radix UI primitives, TipTap, node:test, Nx
+
+---
+
+> Local workflow note: `docs/plans/` is local-only and must remain untracked. Do not include this plan file in commits.
+
+### Task 1: Patch the owning spec and point-of-use docs for the expanded admin route set
+
+**Files:**
+
+- Modify: `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+- Modify: `packages/studio/README.md`
+- Modify: `apps/studio-example/README.md`
+
+**Step 1: Write the spec delta for the extra mock-backed admin pages**
+
+Add `/admin/media`, `/admin/schema`, `/admin/workflows`, and `/admin/api` to
+the Studio internal route list in `SPEC-006`, and describe them as
+runtime-owned navigable surfaces that are allowed to render shell-only/mock
+content in this phase.
+
+```md
+- `/admin/media` - Media library shell surface
+- `/admin/schema` - Schema explorer shell surface
+- `/admin/workflows` - Workflow shell surface
+- `/admin/api` - API playground shell surface
+```
+
+**Step 2: Align the runtime package and host-app docs**
+
+Update `packages/studio/README.md` and `apps/studio-example/README.md` so both
+documents describe the expanded `/admin/*` route set and clarify that the
+additional pages are present as UI surfaces before backend wiring lands.
+
+**Step 3: Run a targeted terminology check**
+
+Run:
+
+```bash
+rg -n "/admin/media|/admin/schema|/admin/workflows|/admin/api|shell-only|mock content" docs/specs/SPEC-006-studio-runtime-and-ui.md packages/studio/README.md apps/studio-example/README.md
+```
+
+Expected: each new route appears in the updated docs.
+
+**Step 4: Run format verification**
+
+Run:
+
+```bash
+bun run format:check
+```
+
+Expected: PASS
+
+**Step 5: Commit the spec/docs delta**
+
+```bash
+git add docs/specs/SPEC-006-studio-runtime-and-ui.md packages/studio/README.md apps/studio-example/README.md
+git commit -m "docs(studio): define expanded admin route surfaces"
+```
+
+### Task 2: Add a runtime-owned stylesheet asset path for the remote Studio bundle
+
+**Files:**
+
+- Modify: `packages/studio/package.json`
+- Modify: `packages/studio/src/lib/build-runtime.ts`
+- Modify: `packages/studio/src/lib/build-runtime.test.ts`
+- Modify: `packages/studio/src/lib/remote-module.ts`
+- Create: `packages/studio/src/lib/runtime-ui/styles.css`
+- Create: `packages/studio/src/lib/runtime-ui/style-installer.ts`
+- Create: `packages/studio/src/lib/runtime-ui/style-installer.test.ts`
+
+**Step 1: Write the failing runtime-style tests**
+
+Add tests that assert:
+
+- `buildStudioRuntimeArtifacts(...)` emits a CSS asset next to the JS entry
+- the emitted CSS filename is derived from the same `buildId`
+- `mount(...)` installs the stylesheet once and cleans up correctly on unmount
+
+```ts
+assert.match(result.cssFile, /^studio-runtime\.[a-f0-9]{16}\.css$/);
+assert.equal(installedLinks[0]?.href.endsWith(result.cssFile), true);
+```
+
+**Step 2: Run the targeted tests to verify failure**
+
+Run:
+
+```bash
+bun --cwd packages/studio test ./src/lib/build-runtime.test.ts ./src/lib/runtime-ui/style-installer.test.ts
+```
+
+Expected: FAIL because the runtime build currently emits only the JS module.
+
+**Step 3: Implement the minimal CSS asset pipeline**
+
+Update `build-runtime.ts` so it also emits a compiled stylesheet asset, and add
+a small installer helper that derives the CSS URL from `import.meta.url` when
+the remote runtime mounts.
+
+```ts
+const stylesheetUrl = new URL(
+  import.meta.url.replace(/\.mjs$/, ".css"),
+).toString();
+
+const removeStyles = installStudioRuntimeStyles(stylesheetUrl);
+```
+
+Keep the first pass simple: one global runtime stylesheet asset owned by
+`@mdcms/studio`.
+
+**Step 4: Re-run the targeted tests**
+
+Run:
+
+```bash
+bun --cwd packages/studio test ./src/lib/build-runtime.test.ts ./src/lib/runtime-ui/style-installer.test.ts
+```
+
+Expected: PASS
+
+**Step 5: Commit the runtime-style slice**
+
+```bash
+git add packages/studio/package.json packages/studio/src/lib/build-runtime.ts packages/studio/src/lib/build-runtime.test.ts packages/studio/src/lib/remote-module.ts packages/studio/src/lib/runtime-ui/styles.css packages/studio/src/lib/runtime-ui/style-installer.ts packages/studio/src/lib/runtime-ui/style-installer.test.ts
+git commit -m "feat(studio): add remote runtime stylesheet assets"
+```
+
+### Task 3: Add runtime-local navigation primitives and admin-shell state
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/remote-studio-app.tsx`
+- Modify: `packages/studio/src/lib/remote-studio-app.test.ts`
+- Create: `packages/studio/src/lib/runtime-ui/mock-data.ts`
+- Create: `packages/studio/src/lib/runtime-ui/utils.ts`
+- Create: `packages/studio/src/lib/runtime-ui/navigation.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/runtime-link.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/layout/admin-layout.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/layout/app-sidebar.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/layout/page-header.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/coming-soon.tsx`
+
+**Step 1: Write the failing runtime-shell tests**
+
+Cover:
+
+- matching and rendering the expanded route set
+- base-path-aware `navigate(...)` behavior
+- active-nav highlighting under `/admin/*`
+- role-aware nav visibility for admin-only pages
+
+```ts
+assert.equal(matchStudioRoute("/api", routes)?.id, "api");
+assert.match(markup, /data-mdcms-nav-item="settings"/);
+assert.doesNotMatch(viewerMarkup, /data-mdcms-nav-item="users"/);
+```
+
+**Step 2: Run the targeted remote-runtime tests to verify failure**
+
+Run:
+
+```bash
+bun --cwd packages/studio test ./src/lib/remote-studio-app.test.ts
+```
+
+Expected: FAIL because the current remote runtime still renders the placeholder
+registry demo.
+
+**Step 3: Implement the local navigation and shell foundations**
+
+Add a small runtime router state layer and use it to power a reusable admin
+layout, sidebar, header, and shared mock-data selectors.
+
+```tsx
+const { pathname, navigate } = useStudioNavigation(context.basePath);
+
+return (
+  <StudioNavigationProvider value={{ pathname, navigate }}>
+    <AdminLayout>{children}</AdminLayout>
+  </StudioNavigationProvider>
+);
+```
+
+Keep `next/link`, `next/navigation`, and `next/font` out of the runtime port.
+
+**Step 4: Re-run the targeted tests**
+
+Run:
+
+```bash
+bun --cwd packages/studio test ./src/lib/remote-studio-app.test.ts
+```
+
+Expected: PASS
+
+**Step 5: Commit the navigation/shell slice**
+
+```bash
+git add packages/studio/src/lib/remote-studio-app.tsx packages/studio/src/lib/remote-studio-app.test.ts packages/studio/src/lib/runtime-ui/mock-data.ts packages/studio/src/lib/runtime-ui/utils.ts packages/studio/src/lib/runtime-ui/navigation.tsx packages/studio/src/lib/runtime-ui/runtime-link.tsx packages/studio/src/lib/runtime-ui/layout/admin-layout.tsx packages/studio/src/lib/runtime-ui/layout/app-sidebar.tsx packages/studio/src/lib/runtime-ui/layout/page-header.tsx packages/studio/src/lib/runtime-ui/coming-soon.tsx
+git commit -m "feat(studio): add runtime admin shell navigation"
+```
+
+### Task 4: Port the shared UI primitives and editor surfaces used by the approved admin pages
+
+**Files:**
+
+- Modify: `packages/studio/package.json`
+- Create: `packages/studio/src/lib/runtime-ui/editor/editor-sidebar.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/editor/tiptap-editor.tsx`

+- Create: `packages/studio/src/lib/runtime-ui/ui/dialog.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/ui/dropdown-menu.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/ui/input.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/ui/label.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/ui/pagination.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/ui/select.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/ui/separator.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/ui/switch.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/ui/table.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/ui/tabs.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/ui/textarea.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/ui/tooltip.tsx`
+
+**Step 1: Write the failing editor and primitive smoke tests**
+
+Add one small rendering test that mounts the document route and asserts the
+ported editor/sidebar surfaces and core primitives render without throwing.
+
+```ts
+assert.match(markup, /Document Editor/);
+assert.match(markup, /data-mdcms-editor-sidebar/);
+```
+
+**Step 2: Run the targeted tests to verify failure**
+
+Run:
+
+```bash
+bun --cwd packages/studio test ./src/lib/remote-studio-app.test.ts
+```
+
+Expected: FAIL because the route components and their primitive dependencies do
+not exist yet.
+
+**Step 3: Port the minimal component set used by the admin pages**
+
+Copy only the primitives and editor surfaces referenced by the approved page
+set. Trim mock-only dependencies that are not used by those pages, and prefer a
+small local theme toggle over bringing `next-themes` into the runtime.
+
+```tsx
+export function StudioButton(props: ButtonHTMLAttributes<HTMLButtonElement>) {
+  return <button data-slot="button" {...props} />;
+}
+```
+
+Update `packages/studio/package.json` with the exact Radix, icon, and TipTap
+runtime dependencies required by this subset.
+
+**Step 4: Re-run the targeted tests**
+
+Run:
+
+```bash
+bun --cwd packages/studio test ./src/lib/remote-studio-app.test.ts
+```
+
+Expected: PASS
+
+**Step 5: Commit the primitive/editor slice**

+**Step 1: Write the failing route-render tests**
+
+Cover the page titles and route ids for:
+
+- `/admin`
+- `/admin/content`
+- `/admin/content/blogpost`
+- `/admin/content/blogpost/1`
+- `/admin/environments`
+- `/admin/users`
+- `/admin/settings`

+```ts
+assert.match(render("/admin/media"), /Media Library/);
+assert.match(render("/admin/api"), /API Playground/);
+assert.match(render("/admin/workflows"), /Coming Soon/);
+```
+
+**Step 2: Run the targeted tests to verify failure**
+
+Run:
+
+```bash
+bun --cwd packages/studio test ./src/lib/remote-studio-app.test.ts
+```
+
+Expected: FAIL because the runtime still renders placeholder surfaces or is
+missing the new routes.
+
+**Step 3: Port the page components and update the route registry**
+
+Wire the new page components into the remote runtime route map and keep the
+current route IDs stable where possible.
+
+```tsx
+const routes: StudioRouteDefinition[] = [
+  { id: "dashboard", path: "/", render: () => <DashboardPage /> },
+  { id: "content.index", path: "/content", render: () => <ContentIndexPage /> },
+  { id: "api", path: "/api", render: () => <ApiPlaygroundPage /> },
+];
+```
+
+Keep the placeholder pages explicit for mock-only surfaces rather than adding
+fake backend calls.
+
+**Step 4: Re-run the targeted tests**

+```
+
+Expected: PASS

+- Modify: `apps/studio-example/README.md`
+- Modify: `packages/studio/src/lib/studio-loader.test.ts`
+- Modify: `packages/studio/src/lib/studio.test.ts`
+
+**Step 1: Add the final regression tests**
+
+Cover:
+
+- loader behavior still mounts the remote runtime with the same context
+- the shell still handles startup errors after the UI swap
+- no route-port work changed bootstrap semantics
+
+```ts
+assert.deepEqual(contexts[0], {
+  apiBaseUrl: "http://localhost:4000",
+  basePath: "/admin",
+  auth: { mode: "cookie" },
+  hostBridge: validHostBridge,
+});
+```
+
+**Step 2: Run the targeted studio tests**
+
+Run:
+
+```bash
+bun --cwd packages/studio test ./src/lib/studio-loader.test.ts ./src/lib/studio.test.ts ./src/lib/remote-studio-app.test.ts
+```
+
+Expected: PASS
+
+**Step 3: Run workspace verification**
+
+Run:
+
+```bash
+bun run format:check
+bun run check
+bun run studio:embed:smoke
+```
+
+Expected: PASS for all three commands, and the smoke check should prove that
+`http://127.0.0.1:4173/admin` renders the new Studio runtime instead of the old
+placeholder.
+
+**Step 4: Update any remaining point-of-use docs**
+
+If the runtime README or smoke-app README still describe the old placeholder UI,
+patch them now so the embed workflow docs match reality.
+
+**Step 5: Commit the verification/docs slice**
+
+```bash
+git add packages/studio/README.md apps/studio-example/README.md packages/studio/src/lib/studio-loader.test.ts packages/studio/src/lib/studio.test.ts

+# CMS-71 and CMS-72 Widget Hints and Custom Editors Design
+
+> Local-only planning note. This file is not canonical product documentation and should remain uncommitted.
+
+## Summary
+
+Combine `CMS-71` and `CMS-72` into one spec-first slice that:
+
+- formalizes the shared `propHints` contract and override precedence
+- validates widget-hint config during local MDX catalog preparation
+- extends the shared auto-form mapping helper so widget hints can override
+  default controls deterministically
+- introduces a Studio-side custom props editor host lifecycle that resolves
+  editors lazily and exposes `loading`, `ready`, `empty`, `error`, and
+  `forbidden` states without pulling in the full `CMS-74` node-view editor UX
+
+## Problem
+
+The current codebase already has:
+
+- local MDX component catalog transport from host config into the embedded
+  Studio runtime
+- extracted prop metadata for default auto-form generation
+- `propHints` passed through as opaque metadata
+- `resolvePropsEditor(componentName)` wired as a synchronous presence check in
+  the runtime diagnostics path
+
+What is still missing:
+
+- a typed and validated `propHints` contract
+- a shared precedence rule between default controls, widget overrides, and
+  `propsEditor`
+- support for all seven widget overrides in the shared MDX mapping layer
+- an actual custom-editor resolution lifecycle with defined UI states and
+  read-only behavior
+
+Without that, downstream work would keep reinterpreting raw `propHints` objects
+inside Studio code, and `CMS-72` would still not have a contract for how custom
+editor loading and failure behave.
+
+## Approved Direction
+
+### Spec ownership
+
+`SPEC-007` remains the owning product contract for both tasks. The required
+spec delta is:
+
+- define a typed `propHints` union
+- define validation rules per widget
+- define deterministic precedence across `propsEditor`, widget hints, and
+  default prop-type mapping
+- define the custom props editor lifecycle states and read-only behavior
+
+No backend contract changes are needed.
+
+### Shared contract boundary
+
+`@mdcms/shared` owns:
+
+- typed `MdxPropHint` definitions
+- runtime validation of `catalog.components[*].propHints`
+- pure override mapping from `extractedProps + propHints` into explicit
+  field-control metadata
+
+This keeps widget semantics reusable across Studio and future local tooling.
+
+### Studio runtime boundary
+
+`@mdcms/studio` owns:
+
+- local validation of host-authored `propHints` during Studio config
+  preparation/loading
+- lazy `resolvePropsEditor(componentName)` handling
+- the custom-editor host lifecycle for the document route surface
+
+The Studio work should stay intentionally thin. It needs to prove the runtime
+can:
+
+- resolve a custom editor asynchronously
+- mount it with `value`, `onChange`, and `readOnly`
+- show the required state surfaces when the editor is missing, fails, or is not
+  editable
+
+It should not implement the full `MdxComponent` node-view props panel from
+`CMS-74`.
+
+### Scope split against CMS-74
+
+Keep out of scope:
+
+- TipTap `MdxComponent` node implementation
+- insertion UI and slash-command integration
+- inline node-view props drawers
+- MDX prop persistence into real component nodes in the editor document
+
+For `CMS-72`, it is sufficient to implement the reusable host/runtime surface
+and prove its lifecycle in the current document-route runtime shell.
+
+## Proposed Contract Shape
+
+### Widget hints
+
+Use a discriminated union for `propHints` entries:
+
+- `{ format: "url" }`
+- `{ widget: "color-picker" }`
+- `{ widget: "textarea" }`
+- `{ widget: "slider", min, max, step? }`
+- `{ widget: "image" }`
+- `{ widget: "select", options }`
+- `{ widget: "hidden" }`
+- `{ widget: "json" }`
+
+Validation rules:
+
+- `format` cannot be combined with `widget`
+- `color-picker`, `textarea`, and `image` only target extracted `string` props
+- `slider` only targets extracted `number` props and requires valid numeric
+  bounds
+- `select` requires a non-empty options list whose values match the target
+  scalar prop kind
+- `hidden` can suppress any extracted prop
+- `json` stays limited to JSON-serializable props and never enables function or
+  ref-like shapes
+
+### Shared auto-form output
+
+Extend the shared auto-form field union to cover:
+
+- `color-picker`
+- `textarea`
+- `slider`
+- `image`
+- `select`
+- `json`
+
+`hidden` should produce no field.
+
+The mapper should accept both `extractedProps` and `propHints`, validate the
+hint against the extracted prop, and then either:
+
+- emit the override control
+- fall back to the default control
+- omit the field for `hidden`
+
+### Custom editor lifecycle
+
+Change the host capability from synchronous resolution to async resolution:
+
+- `resolvePropsEditor(name): Promise<unknown | null>`
+
+The runtime host model should expose these states:
+
+- `loading`
+- `ready`
+- `empty`
+- `error`
+- `forbidden`
+
+`ready` mounts the resolved editor with:
+
+- `value`
+- `onChange`
+- `readOnly`
+
+## Testing Strategy
+
+Use TDD in this order:
+
+1. spec delta
+2. shared contract validation tests
+3. shared override-mapping tests
+4. Studio loader/runtime tests for async editor resolution
+5. runtime rendering tests for lifecycle states and `onChange`
+
+## Risks and Constraints
+
+- The spec currently names the `image` widget but does not define a richer media
+  payload shape. Keep `image` string-backed for this slice so the implementation
+  stays compatible with current specs and does not pull Post-MVP media contracts
+  into MVP editor work.
+- The current document route is still a mock runtime shell. The custom-editor
+  lifecycle should be implemented as a reusable runtime surface that can later
+  plug into `CMS-74`, not as one-off page-only logic.
+- `docs/plans/` is local-only in this repo, so planning artifacts must remain
+  untracked.

+# CMS-71 and CMS-72 Widget Hints and Custom Editors Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Implement the shared widget-hint override contract and the Studio custom props editor lifecycle so local MDX component metadata can drive validated auto-form overrides and lazily resolved custom editors with deterministic UI states.
+
+**Architecture:** Update `SPEC-007` first so the product contract explicitly defines typed `propHints`, precedence, validation rules, async custom-editor resolution, and lifecycle states. Then extend `@mdcms/shared` to type and validate widget hints and map them into explicit field controls. Finally, update `@mdcms/studio` to treat props editor resolution as an async lifecycle, render the required state surfaces on the document route, and prove `value` / `onChange` behavior with targeted runtime tests without pulling in full `CMS-74` node-view work.
+
+**Tech Stack:** Bun, Nx, TypeScript, node:test, Zod, React, Markdown specs/READMEs
+
+---
+
+### Task 1: Apply the Owning Spec Delta
+
+**Files:**
+
+- Modify: `docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
+
+**Step 1: Update the spec before code**
+
+Add the approved contract language for:
+
+- typed `MdxPropHint`
+- `propHints` validation rules
+- precedence between `propsEditor`, widget overrides, and default controls
+- async `resolvePropsEditor(...)`
+- custom props editor lifecycle states
+- `value`, `onChange`, and `readOnly`
+
+**Step 2: Verify the spec wording**
+
+Run: `rg -n "MdxPropHint|resolvePropsEditor|loading|empty|error|forbidden|Widget-hint precedence" docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
+
+Expected: all required lifecycle and precedence concepts are present in the owning spec.
+
+### Task 2: Add Shared Widget Hint Types and Validators
+
+**Files:**
+
+- Modify: `packages/shared/src/lib/contracts/extensibility.ts`
+- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
+- Modify: `packages/shared/README.md`
+
+**Step 1: Write the failing contract tests**
+
+Add coverage for:
+
+- accepted `propHints` shapes for all 7 widgets plus `{ format: "url" }`
+- rejected mixed `{ format, widget }` shapes
+- rejected invalid slider config
+- rejected empty `select.options`
+- rejected invalid option value types
+
+**Step 2: Run the contract test to verify it fails**
+
+Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
+
+Expected: FAIL because `propHints` is still opaque.
+
+**Step 3: Implement the shared contract**
+
+Add:
+
+- `MdxSelectOptionValue`
+- `MdxSelectOption`
+- `MdxPropHint`
+- typed `propHints?: Record<string, MdxPropHint>`
+- strict Zod validation for `catalog.components[*].propHints`
+
+Update the README with the supported widget-hint contract and precedence notes.
+
+**Step 4: Re-run the contract test**
+
+Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
+
+Expected: PASS
+
+### Task 3: Extend the Shared Auto-Form Mapper for Overrides
+
+**Files:**
+
+- Modify: `packages/shared/src/lib/mdx/auto-form.ts`
+- Modify: `packages/shared/src/lib/mdx/auto-form.test.ts`
+- Modify: `packages/shared/README.md`
+
+**Step 1: Write the failing mapper tests**
+
+Cover:
+
+- default mapping still works unchanged when `propHints` is missing
+- each widget override emits the expected control
+- `hidden` omits the field
+- valid widget overrides take precedence over default mapping
+- invalid or incompatible hints throw deterministic validation errors
+- JSON widget emits a JSON field instead of being skipped
+
+**Step 2: Run the mapper test to verify it fails**
+
+Run: `bun test packages/shared/src/lib/mdx/auto-form.test.ts`
+
+Expected: FAIL because the helper does not accept or honor widget hints.
+
+**Step 3: Implement the override mapper**
+
+Update the public field union and mapping helper to accept:
+
+- `extractedProps`
+- `propHints`
+
+Validate per-prop hint compatibility and emit explicit controls for:
+
+- `color-picker`
+- `textarea`
+- `slider`
+- `image`
+- `select`
+- `json`
+
+Keep `hidden` as omission.
+
+**Step 4: Re-run shared MDX tests**
+
+Run: `bun test packages/shared/src/lib/mdx/auto-form.test.ts packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/src/lib/mdx/extracted-props.test.ts`
+
+Expected: PASS
+
+### Task 4: Validate Host Authored Hints During Studio Config Preparation
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/studio.ts`
+- Modify: `packages/studio/src/lib/studio.test.ts`
+
+**Step 1: Write the failing preparation tests**
+
+Cover:
+
+- valid `propHints` survive prepared config
+- invalid `propHints` fail during config preparation with deterministic errors
+- extracted props and prepared metadata still include valid hints
+
+**Step 2: Run the preparation test to verify it fails**
+
+Run: `bun test packages/studio/src/lib/studio.test.ts`
+
+Expected: FAIL because Studio preparation does not validate hint semantics yet.
+
+**Step 3: Implement validation**
+
+Reuse the shared validator path so local Studio preparation rejects invalid host
+config before the runtime receives it.
+
+**Step 4: Re-run the preparation test**
+
+Run: `bun test packages/studio/src/lib/studio.test.ts`
+
+Expected: PASS
+
+### Task 5: Implement Async Custom Props Editor Resolution
+
+**Files:**
+
+- Modify: `packages/shared/src/lib/contracts/extensibility.ts`
+- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
+- Modify: `packages/studio/src/lib/studio-loader.ts`
+- Modify: `packages/studio/src/lib/studio-loader.test.ts`
+
+**Step 1: Write the failing loader/runtime contract tests**
+
+Cover:
+
+- `resolvePropsEditor` must be async
+- loaded local props editors are exposed as async resolver results
+- `null` is returned when no editor exists
+
+**Step 2: Run the relevant tests to verify failure**
+
+Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts packages/studio/src/lib/studio-loader.test.ts`
+
+Expected: FAIL because the resolver is currently synchronous.
+
+**Step 3: Implement async resolution**
+
+Update the shared contract and Studio loader to expose:
+
+- `resolvePropsEditor(name): Promise<unknown | null>`
+
+Preserve local loader behavior and host-bridge composition.
+
+**Step 4: Re-run the loader/runtime contract tests**
+
+Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts packages/studio/src/lib/studio-loader.test.ts`
+
+Expected: PASS
+
+### Task 6: Add the Studio Custom Editor Host Lifecycle
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/remote-studio-app.tsx`
+- Modify: `packages/studio/src/lib/remote-studio-app.test.ts`
+- Create: `packages/studio/src/lib/mdx-props-editor-host.tsx`
+- Create: `packages/studio/src/lib/mdx-props-editor-host.test.tsx`
+- Modify: `packages/studio/README.md`
+
+**Step 1: Write the failing lifecycle tests**
+
+Cover:
+
+- `loading` while async editor resolution is pending
+- `ready` when an editor resolves and receives `value`, `onChange`, `readOnly`
+- `empty` when resolver returns `null` and no auto-form fields exist
+- `error` when resolver rejects or render throws
+- `forbidden` when read-only mode blocks mutation
+- fallback to auto-form when no executable editor exists but generated controls do
+
+**Step 2: Run the lifecycle tests to verify failure**
+
+Run: `bun test packages/studio/src/lib/remote-studio-app.test.ts`
+
+Expected: FAIL because the runtime currently only exposes diagnostics text and has no lifecycle host.
+
+**Step 3: Implement the host component**
+
+Build a small reusable host that:
+
+- resolves editors lazily
+- manages lifecycle state
+- passes `value`, `onChange`, and `readOnly`
+- renders fallback auto-form metadata when appropriate
+
+Use the current document-route runtime surface as the proof integration point.
+
+**Step 4: Re-run the Studio runtime tests**
+
+Run: `bun test packages/studio/src/lib/remote-studio-app.test.ts packages/studio/src/lib/studio-loader.test.ts`
+
+Expected: PASS
+
+### Task 7: Run Task Verification

+# CMS-73 TipTap Baseline and Nested MDX Content Design
+
+> Local-only planning note. This file is not canonical product documentation and should remain uncommitted.
+
+## Summary
+
+Implement `CMS-73` as a real editor-core upgrade in `@mdcms/studio` that:
+
+- absorbs the missing TipTap editor baseline currently expected from earlier
+  roadmap slices
+- keeps the current document-route UI shell and editor-panel layout intact
+- introduces a generic `MdxComponent` TipTap node for wrapper and void MDX
+  components
+- enables nested rich-text editing for wrapper component `children` inside the
+  same editor document and autosave path
+- proves nested MDX round-tripping through targeted serialization and editor
+  tests
+
+## Spec Delta Summary
+
+No new spec text is required before implementation.
+
+The owning contract is already present in
+`docs/specs/SPEC-007-editor-mdx-and-collaboration.md`:
+
+- Markdown/MDX content is edited through TipTap.
+- MDX components are modeled as a single generic `MdxComponent` node.
+- Wrapper components expose a `block*` content hole for nested child content.
+- Nested child content is edited inline within the component block.
+- Serialization recursively renders wrapper children back into MDX.
+
+This task is therefore an implementation catch-up to an existing spec-owned
+contract, not a new product-surface change.
+
+## Current Gap
+
+The current repo already has:
+
+- a reusable markdown pipeline in
+  `packages/studio/src/lib/markdown-pipeline.ts`
+- local MDX catalog transport and extracted-prop metadata in
+  `@mdcms/shared` and `@mdcms/studio`
+- a runtime document route shell with save-state scaffolding and sidebars
+
+What is still missing:
+
+- a real `@tiptap/react` editor surface on the document route
+- MDX-aware TipTap extensions for parsing/rendering component nodes
+- a generic `MdxComponent` node implementation
+- inline wrapper-node content editing
+- round-trip tests for nested wrapper content
+
+The current
+`packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.tsx`
+remains a mock toolbar plus textarea, which is below the baseline already
+described by `SPEC-007`.
+
+## Approved Direction
+
+### Keep the current document UI
+
+Retain the current editor-page shell:
+
+- header
+- locale tabs
+- publish dialog
+- right sidebar
+- overall editor panel footprint
+
+This task upgrades behavior and editor internals, not the surrounding document
+page layout.
+
+### Absorb the missing baseline into CMS-73
+
+Treat the missing “real TipTap editor” work as part of `CMS-73` so the task can
+actually satisfy its own nested-content acceptance criteria and produce a
+usable dependency for `CMS-74`.
+
+This avoids:
+
+- building throwaway adapter code on top of the mock textarea
+- splitting foundational editor work across another unplanned slice
+- forcing `CMS-74` to redo baseline editor integration before it can add node
+  views and insertion UX
+
+## Architecture
+
+### Package ownership
+
+`@mdcms/shared` continues to own:
+
+- the MDX catalog contract
+- extracted prop metadata
+- the `children: { type: "rich-text" }` signal used to distinguish wrapper
+  components
+
+`@mdcms/studio` owns:
+
+- TipTap editor instantiation
+- MDX parsing and rendering integration
+- the generic `MdxComponent` extension
+- wrapper node-view rendering and nested editing
+- document-route editor UI wiring
+
+No backend or SDK contract changes are needed for this task because the editor
+still persists a single markdown/MDX body string.
+
+### Editor document model
+
+Use one top-level TipTap document as the only local editor state.
+
+- normal markdown blocks live directly in that document
+- wrapper MDX components become `MdxComponent` nodes with nested `content`
+- void MDX components become self-closing `MdxComponent` nodes with no child
+  content
+
+Nested wrapper content must not be modeled as a separate draft state or a
+second disconnected editor document. The editable child region should be driven
+by the same ProseMirror tree so page-level change handling and serialization
+remain whole-document operations.
+
+### Generic `MdxComponent` node
+
+Introduce a single editor node type that carries:
+
+- `componentName`
+- `props`
+- wrapper-vs-void semantics derived from the local MDX catalog
+
+Behavior:
+
+- if `extractedProps.children?.type === "rich-text"`, treat the component as a
+  wrapper and allow `block*` child content
+- otherwise treat it as void and serialize it as self-closing MDX
+
+This keeps the editor schema stable as the host app adds or removes registered
+components.
+
+### Markdown/MDX pipeline
+
+Extend the existing markdown pipeline rather than replacing it.
+
+- keep `parseMarkdownToDocument(...)`
+- keep `serializeDocumentToMarkdown(...)`
+- keep `roundTripMarkdown(...)`
+
+Add MDX-component-aware extensions so the pipeline can:
+
+- parse MDX component syntax into `MdxComponent` nodes
+- preserve JSON props in node attrs
+- recursively serialize wrapper children back into markdown within opening and
+  closing tags
+
+The implementation should stay compatible with the current spec direction of a
+custom tokenizer plus custom TipTap extension. If the parser work exposes a
+clear limitation for nested MDX, the limitation should be documented in code
+comments for the later fallback evaluation path already named in `SPEC-007`.
+
+### Node-view UI
+
+Wrapper node views should remain minimal in `CMS-73`.
+
+They need:
+
+- visible wrapper chrome so editors can identify the component boundary
+- component name display
+- a nested editable content region using the TipTap node-view content hole
+
+They do not need in this slice:
+
+- full host-app live preview rendering
+- component insertion panel
+- slash-command integration
+- polished props panel selection syncing
+
+That work remains aligned with `CMS-74`.
+
+## Scope Boundaries
+
+### In scope
+
+- replace the mock textarea editor internals with a real TipTap React editor
+- keep the current route-level UI shell
+- add the generic `MdxComponent` editor extension
+- support wrapper child-content editing inside component nodes
+- keep nested content in the same local document state and `onChange` path
+- serialize wrapper children back to MDX
+- document foundational behavior at point of use
+
+### Out of scope
+
+- full component insertion UX
+- slash command / toolbar insertion flows
+- host-app live component preview inside node views
+- deep props-panel selection synchronization
+- collaboration transport / Yjs wiring
+
+`SPEC-007` mentions collaboration participation for nested content, but that
+same spec also defers collaboration transport post-MVP. For this slice, the
+practical equivalent is that nested content stays in the same local editor
+document and autosave pipeline so future collaboration can bind to the same
+document tree later.
+
+## Testing Strategy
+
+Use TDD in this order:
+
+1. markdown-pipeline tests for wrapper parse/serialize round trips
+2. focused `MdxComponent` extension tests for wrapper-vs-void behavior
+3. React editor tests for rendering the real TipTap surface and updating nested
+   wrapper content
+4. route-level integration checks that document save-state callbacks still fire
+   from editor changes
+
+Verification should specifically prove:
+
+- wrapper MDX parses into editor state without dropping children
+- nested markdown formatting inside wrapper children round-trips correctly
+- editing nested child content updates the parent document serialization
+- current document-page shell behavior still works with the upgraded editor
+
+## Risks and Constraints
+
+- The current document route is a runtime-shell scaffold, so the real editor
+  integration should be implemented as reusable `@mdcms/studio` infrastructure
+  rather than page-only glue.
+- The task intentionally stops short of full `CMS-74` preview and insertion
+  UX; otherwise the slice would sprawl beyond the nested-content foundation.
+- `docs/plans/` is local-only in this repo, so this design note must remain
+  uncommitted.

+# CMS-73 TipTap Baseline and Nested MDX Content Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Replace the mock document editor internals with a real TipTap-based editor in `@mdcms/studio`, then add generic `MdxComponent` wrapper-node support so nested MDX child content can be edited inline and serialized through the same local document/autosave pipeline.
+
+**Architecture:** Keep the current document-route UI shell and sidebar layout, but replace the textarea-based mock editor with a real `@tiptap/react` editor backed by the existing markdown pipeline. Introduce a reusable generic `MdxComponent` TipTap extension plus a minimal node view for wrapper components whose `children` prop is typed as `rich-text` in the local MDX catalog. Keep nested child content inside the same ProseMirror document tree so page-level change handling still serializes one markdown/MDX body string.
+
+**Tech Stack:** Bun, Nx, TypeScript, node:test, React, TipTap (`@tiptap/core`, `@tiptap/react`, `@tiptap/markdown`, `@tiptap/starter-kit`)
+
+---
+
+### Task 1: Lock Down the Missing Editor-Core Contract With Failing Tests
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/markdown-pipeline.test.ts`
+- Create: `packages/studio/src/lib/mdx-component-extension.test.ts`
+
+**Step 1: Add failing round-trip tests for wrapper MDX**
+
+Cover:
+
+- parsing and serializing `<Callout>Plain text</Callout>`
+- nested markdown inside wrapper children
+- stable second-pass serialization for wrapper content
+
+**Step 2: Add failing extension tests**
+
+Cover:
+
+- wrapper classification when `children` is extracted as `rich-text`
+- void classification when `children` is absent
+- prop retention across parse/render for both node shapes
+
+**Step 3: Run the tests to verify failure**
+
+Run: `bun test packages/studio/src/lib/markdown-pipeline.test.ts packages/studio/src/lib/mdx-component-extension.test.ts`
+
+Expected: FAIL because the current markdown pipeline has no MDX-component extension or wrapper-child support.
+
+### Task 2: Implement the Generic `MdxComponent` Extension and MDX Parsing Helpers
+
+**Files:**
+
+- Create: `packages/studio/src/lib/mdx-component-extension.ts`
+- Modify: `packages/studio/src/lib/markdown-pipeline.ts`
+- Modify: `packages/studio/src/lib/package-boundaries.test.ts`
+
+**Step 1: Implement the extension**
+
+Add a reusable generic TipTap node extension that carries:
+
+- `componentName`
+- `props`
+- wrapper-vs-void handling
+
+Keep wrapper detection catalog-aware and driven by extracted `children` metadata.
+
+**Step 2: Extend the markdown pipeline**
+
+Update the pipeline helpers so they can accept the MDX catalog context needed to:
+
+- parse MDX component tokens into `MdxComponent` nodes
+- serialize wrapper children recursively back into MDX
+- preserve existing plain-markdown behavior for documents without MDX components
+
+**Step 3: Re-run the failing editor-core tests**
+
+Run: `bun test packages/studio/src/lib/markdown-pipeline.test.ts packages/studio/src/lib/mdx-component-extension.test.ts`
+
+Expected: PASS
+
+### Task 3: Replace the Mock Textarea With a Real TipTap React Editor
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.test.tsx`
+
+**Step 1: Add failing component tests**
+
+Cover:
+
+- initial markdown loads into the editor
+- editor changes call `onChange` with serialized markdown/MDX
+- wrapper child edits flow through the same callback as top-level edits
+
+**Step 2: Run the component tests to verify failure**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.test.tsx`
+
+Expected: FAIL because the current component is still a mock textarea and does not mount TipTap.
+
+**Step 3: Implement the real editor surface**
+
+Replace the textarea internals with:
+
+- `@tiptap/react` editor setup
+- the existing toolbar chrome wired to actual editor commands where already practical
+- serialization via the updated markdown pipeline
+- minimal wrapper-node rendering support
+
+Keep the current editor-panel footprint and surrounding chrome intact.
+
+**Step 4: Re-run the component tests**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.test.tsx`
+
+Expected: PASS
+
+### Task 4: Add Minimal Wrapper Node Views for Nested Child Editing
+
+**Files:**
+
+- Create: `packages/studio/src/lib/runtime-ui/components/editor/mdx-component-node-view.tsx`
+- Modify: `packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.tsx`
+- Modify: `packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.test.tsx`
+
+**Step 1: Add failing node-view behavior tests**
+
+Cover:
+
+- wrapper nodes render component chrome plus an editable child region
+- void nodes do not expose nested content areas
+- nested child edits preserve wrapper boundaries in serialized output
+
+**Step 2: Run the relevant tests to verify failure**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.test.tsx`
+
+Expected: FAIL because wrapper node views do not exist yet.
+
+**Step 3: Implement the node view**
+
+Build a minimal node view that:
+
+- shows the component name and wrapper boundary
+- uses the TipTap content hole for wrapper child editing
+- avoids full preview or insertion UX that belongs to `CMS-74`
+
+**Step 4: Re-run the editor tests**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.test.tsx`
+
+Expected: PASS
+
+### Task 5: Wire the Document Route to the Real Editor Without Changing the Shell UI
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/runtime-ui/pages/content-document-page.tsx`
+- Modify: `packages/studio/src/lib/runtime-ui/components/editor/editor-sidebar.tsx`
+
+**Step 1: Add a failing document-route behavior test if coverage is missing**
+
+Cover:
+
+- editor changes still drive the save-status indicator path
+- the existing page shell continues to render with the upgraded editor
+- the optional MDX props sidebar surface still mounts unchanged when context is present
+
+**Step 2: Run the affected tests or add targeted coverage**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.test.tsx packages/studio/src/lib/remote-studio-app.test.ts`
+
+Expected: FAIL or expose missing route/editor coupling.
+
+**Step 3: Implement the route wiring**
+
+Pass real content and catalog context into the upgraded editor component while:
+
+- preserving the current header, publish dialog, locale tabs, and sidebar layout
+- keeping save-state updates driven by editor changes
+- avoiding unrelated UI redesign
+
+**Step 4: Re-run the route-level checks**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.test.tsx packages/studio/src/lib/remote-studio-app.test.ts`
+
+Expected: PASS
+
+### Task 6: Document the Foundation at Point of Use
+
+**Files:**
+
+- Modify: `packages/studio/README.md`
+- Modify: `packages/studio/src/lib/markdown-pipeline.ts`
+- Modify: `packages/studio/src/lib/mdx-component-extension.ts`
+
+**Step 1: Add concise implementation comments**
+
+Document:
+
+- why wrapper child content stays in the same ProseMirror document

+
+**Step 2: Update the package README**
+
+Add notes for:
+
+- the real TipTap editor baseline
+- generic `MdxComponent` support
+- nested wrapper-content serialization support
+
+**Step 3: Verify the docs reference the new behavior**
+
+Run: `rg -n "MdxComponent|nested|wrapper|TipTap" packages/studio/README.md packages/studio/src/lib/markdown-pipeline.ts packages/studio/src/lib/mdx-component-extension.ts`
+
+Expected: the foundational behavior is described at the point of use.

+# CMS-74 MDX Component Editor Design
+
+Date: 2026-03-26
+Task: `CMS-74 - Implement MdxComponent node view insert/edit/serialize/live preview`
+
+## Notes
+
+- This design doc is intentionally local-only under `docs/plans/` per repo workflow.
+- The owning spec is [SPEC-007](../specs/SPEC-007-editor-mdx-and-collaboration.md).
+- No spec delta is required before implementation. The task is already fully specified in `SPEC-007`.
+
+## Spec Delta Summary
+
+1. No new spec text is needed.
+2. The affected behavior is the document editor's MDX component insertion, selection-bound prop editing, live preview, and MDX round-tripping.
+3. Acceptance criteria 1-7 rely on the existing `SPEC-007` sections for:
+   - generic `MdxComponent` node behavior
+   - void vs wrapper semantics
+   - local catalog-backed insertion
+   - custom-editor and auto-form prop editing
+   - inline preview through the host bridge
+   - lifecycle states: `loading`, `empty`, `error`, `forbidden`
+
+## Current State
+
+The repo already contains most of the substrate for `CMS-74`:
+
+- `packages/studio/src/lib/mdx-component-extension.ts`
+  - generic `mdxComponent` TipTap node
+  - MDX tokenizer/parser/renderer
+  - void vs wrapper serialization behavior
+- `packages/studio/src/lib/mdx-props-editor-host.tsx`
+  - custom props editor lifecycle
+  - auto-form fallback
+  - `loading`, `empty`, `error`, and `forbidden` states
+- `packages/studio/src/lib/studio-loader.ts`
+  - local MDX catalog preparation
+  - host bridge wiring
+  - async props editor resolution
+- `packages/studio/src/lib/runtime-ui/components/editor/mdx-component-node-view.tsx`
+  - baseline node chrome for wrapper and void components
+
+The main gap is editor integration:
+
+- the toolbar still marks component insertion as planned-only
+- there is no slash-command support
+- the props panel is catalog-driven instead of selection-driven
+- the node view does not yet render inline host-app preview
+- there is no shared insertion controller used by both entrypoints
+
+## Decision
+
+Implement one shared MDX component insertion and editing flow with two entrypoints:
+
+1. toolbar picker
+2. `/` slash command
+
+Both entrypoints must use the same catalog source, selection rules, insertion defaults, and permission gating.
+
+## Architecture
+
+### 1. Shared insertion controller
+
+Introduce editor-local MDX helpers that:
+
+- read the MDX component catalog from `StudioMountContext`
+- infer whether a catalog entry is `void` or `wrapper`
+- insert a generic `mdxComponent` node with:
+  - `componentName`
+  - `props`
+  - `isVoid`
+- create a stable default insertion outcome:
+  - void components insert as self-closing nodes with empty content
+  - wrapper components insert with an empty content hole and focus moves into the wrapper body
+
+This controller becomes the single insertion path for both toolbar and slash command entrypoints.
+
+### 2. Editor-owned MDX selection state
+
+`TipTapEditor` becomes the owner of:
+
+- current selected `mdxComponent` node
+- picker open/closed state
+- insertion mode (`toolbar` or `slash`)
+- read-only / forbidden behavior passed down to editing surfaces
+
+The props panel must bind to the selected node, not to an arbitrary catalog entry.
+
+### 3. Toolbar picker and slash command
+
+Add one picker UI component that can be opened from:
+
+- the toolbar `Insert Component` button
+- a slash-command extension when the user types `/`
+
+The picker must show:
+
+- component name
+- optional description
+- component kind badge: `Void` or `Wrapper`
+
+The picker state contract must cover:
+
+- `ready`: list available components
+- `empty`: no local components registered
+- `forbidden`: list visible but insertion disabled
+
+### 4. Selection-bound props editing
+
+Replace the current catalog proof-surface behavior with selection-bound editing:
+
+- selecting a component node reveals the props panel for that node
+- prop mutations update node attrs immediately
+- custom editor lifecycle remains owned by `MdxPropsEditorHost`
+- auto-form fallback still derives from `extractedProps` + `propHints`
+
+Lifecycle expectations:
+
+- `loading`: async custom editor pending
+- `ready`: custom editor resolved and mounted
+- `empty`: no editable props for this node
+- `error`: resolver rejects or render boundary fails
+- `forbidden`: session may inspect but not mutate
+
+### 5. Inline preview
+
+The node view must render the actual host-app component inside the editor canvas via `context.hostBridge.renderMdxPreview(...)`.
+
+Preview behavior:
+
+- preview rerenders when node props change
+- preview remains visible in read-only mode
+- missing host component resolution produces a deterministic fallback instead of silent blank output
+- preview mounting always cleans up on node change/unmount
+
+### 6. Serialization
+
+Keep the existing generic node and extend tests so the pipeline proves:
+
+- parse -> edit -> serialize for void components
+- parse -> edit -> serialize for wrapper components
+- prop edits preserve component structure
+- wrapper child content continues to serialize as nested markdown
+
+## UI Behavior
+
+### Insertion
+
+1. User opens insertion via toolbar or `/`.
+2. Shared picker lists components from `context.mdx.catalog.components`.
+3. User selects one component.
+4. Editor inserts the generic node with correct `isVoid`.
+5. The newly inserted node becomes selected.
+6. The sidebar props panel opens for that node.
+7. For wrapper components, focus may move into the nested body after insertion.
+
+### Editing
+
+- Clicking or selecting a component node activates the component panel.
+- Prop edits update node attrs immediately.
+- Preview rerenders from the same local document state.
+- Wrapper child content stays editable in the document flow through the existing content hole.
+
+### Read-only and forbidden
+
+- Preview remains visible.
+- Picker may remain discoverable, but insertion actions are disabled.
+- Prop editors mount in inspection mode where applicable, but `onChange` cannot mutate node attrs.
+
+## Testing Strategy
+
+### Unit and integration coverage
+
+- extend `mdx-component-extension` tests for round-trip edits
+- add editor command tests through `createDocumentEditor(...)`
+- add picker and selection helper tests
+- add node-view tests for preview and fallback states
+- add props-panel tests for selection-bound behavior
+
+### Verification target
+
+Task verification calls for node-view e2e tests. Within the current package test setup, the implementation should at minimum add editor integration tests that exercise insertion, selection, and serialization end-to-end through the TipTap editor API. If the existing runtime test surface can support a heavier React integration path without new infrastructure, add that as well.
+
+## Scope Boundaries
+
+In scope:
+
+- generic `mdxComponent` insertion flow
+- toolbar picker
+- slash command
+- selection-bound prop editing
+- inline preview
+- lifecycle states required by spec
+- round-trip serialization coverage
+- README / inline documentation updates
+
+Out of scope:
+
+- generalized editor command palette
+- unrelated slash actions
+- collaboration transport
+- backend API changes
+- broader media workflows beyond existing prop widget contracts

+# CMS-74 MDX Component Editor Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Implement shared toolbar and slash-command MDX component insertion, selection-bound props editing, inline host-app preview, and round-trip coverage for the generic `mdxComponent` editor node.
+
+**Architecture:** Keep the existing generic `mdxComponent` TipTap extension and layer editor-owned selection/insertion behavior on top of it. Both insertion entrypoints use one catalog-backed controller, while the sidebar and node view bind to the currently selected MDX component node and reuse the existing props-editor lifecycle and host-bridge preview contracts.
+
+**Tech Stack:** Bun, Nx, TypeScript, React 19, TipTap 3, node:test
+
+---

+
+Add tests that prove:
+
+- the panel follows the selected node instead of arbitrary catalog selection
+- prop edits update selected node attrs
+- preview uses host-bridge rendering with current component name and props
+- deterministic fallback and `forbidden` behavior render correctly
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/components/editor/mdx-component-node-view.test.tsx packages/studio/src/lib/mdx-props-editor-host.test.tsx`
+Expected: FAIL because selection-bound preview and panel wiring are not implemented yet.
+
+**Step 3: Write minimal implementation**
+
+Wire the editor selection state into:
+
+- the sidebar props panel
+- the node view preview surface
+- node-attr updates
+
+Keep preview cleanup explicit on rerender and unmount.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/components/editor/mdx-component-node-view.test.tsx packages/studio/src/lib/mdx-props-editor-host.test.tsx`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/studio/src/lib/runtime-ui/components/editor/mdx-props-panel.tsx packages/studio/src/lib/runtime-ui/components/editor/mdx-component-node-view.tsx packages/studio/src/lib/runtime-ui/components/editor/mdx-component-node-view.test.tsx packages/studio/src/lib/mdx-props-editor-host.tsx packages/studio/src/lib/mdx-props-editor-host.test.tsx packages/studio/src/lib/runtime-ui/pages/content-document-page.tsx
+git commit -m "feat(studio): bind mdx props editing to selected nodes"
+```
+
+### Task 5: Document the operator and developer-visible behavior and run verification
+
+**Files:**
+
+- Modify: `packages/studio/README.md`
+- Modify: `packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.tsx`
+
+**Step 1: Write the failing test**
+
+Add or update the narrowest test needed if documentation or labels require a behavior assertion, such as toolbar label or picker copy.
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.test.tsx`
+Expected: FAIL if a new behavior assertion is added, or skip if documentation-only.
+
+**Step 3: Write minimal implementation**
+
+Update:
+
+- package README for toolbar + slash insertion and selection-bound props editing
+- concise inline comments where the shared insertion / preview lifecycle is non-obvious
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test packages/studio/src`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/studio/README.md packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.tsx
+git commit -m "docs(studio): document mdx component editor flow"
+```
+
+### Task 6: Final verification
+
+**Files:**
+
+- Verify only
+
+**Step 1: Run focused package tests**
+
+Run: `bun test packages/studio/src`
+Expected: PASS
+
+**Step 2: Run package type/build checks**
+
+Run: `bun nx build studio && bun nx typecheck studio`
+Expected: PASS
+
+**Step 3: Run workspace baseline checks required by repo policy**
+
+Run: `bun run format:check && bun run check`
+Expected: PASS
+
+**Step 4: Confirm local-only files remain unstaged**
+
+Run: `git status --short`
+Expected: `docs/plans/`, `ROADMAP_TASKS.md`, `AGENTS.md`, and other local-only files remain untracked and unstaged.

+# CMS-85 SDK Read Client Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Implement a thin read-focused SDK client in `@mdcms/sdk` with `createClient`, `get`, and `list`, including deterministic routing and error parsing.
+
+**Architecture:** Build a small fetch-based client in `packages/sdk` that maps directly to the content API. Keep the implementation schema-agnostic for reads, centralize request construction and response parsing, and cover behavior with Bun `node:test` tests using fetch stubs instead of a live server.
+
+**Tech Stack:** TypeScript, Bun test runner (`node:test`), workspace package exports, shared API/error contract types from `@mdcms/shared`

+
+**Step 2:** Write a failing test in `packages/sdk/src/lib/sdk.test.ts` for `createClient().list()` unwrapping `{ data, pagination }`.
+
+**Step 3:** Run `cd packages/sdk && bun test ./src/lib/sdk.test.ts`.

+# CMS-85 SDK Spec Alignment Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Align the SDK spec with the agreed read-focused contract and capture the deferred schema-hash pinning decision for future write clients.
+
+**Architecture:** Update the owning SDK spec so it no longer claims runtime-fetched schema can create compile-time typing, define `resolve` as a read option rather than a separate method, and record schema-hash pinning as a proposed ADR instead of an implied runtime cache behavior.
+
+**Tech Stack:** Markdown documentation under `docs/specs/` and `docs/adrs/`
+
+---
+
+### Task 1: Update the SDK spec
+
+**Files:**
+
+- Modify: `docs/specs/SPEC-008-cli-and-sdk.md`
+
+**Step 1:** Replace the misleading runtime typing language with a read-focused SDK contract.
+
+**Step 2:** Define `resolve` as an option on `get` and `list`, not as a standalone SDK method.
+
+**Step 3:** Clarify routing defaults and per-call overrides.
+
+**Step 4:** State that schema-aware writes and schema hash pinning are deferred.
+
+### Task 2: Record the deferred decision
+
+**Files:**
+
+- Create: `docs/adrs/ADR-006-schema-hash-pinning-for-write-clients.md`
+- Modify: `docs/adrs/README.md`
+
+**Step 1:** Create a proposed ADR describing the open schema-hash pinning question.
+
+**Step 2:** Document the preferred direction and rejected auto-refresh approach.
+
+**Step 3:** Update the ADR catalog to list the proposed ADR.
+
+### Task 3: Verify the doc delta
+
+**Files:**
+
+- Review: `docs/specs/SPEC-008-cli-and-sdk.md`
+- Review: `docs/adrs/ADR-006-schema-hash-pinning-for-write-clients.md`
+- Review: `docs/adrs/README.md`
+
+**Step 1:** Re-read the changed sections for spec/ADR consistency.
+
+**Step 2:** Run targeted validation on the touched docs.
+
+**Step 3:** Confirm local-only planning files remain unstaged.

+# Compose Dev Studio Runtime Watch Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Make `docker-compose.dev.yml` rebuild the Studio runtime bundle automatically when `packages/studio/src/**` changes, without restarting the stack.
+
+**Architecture:** Keep the existing startup-owned Studio runtime publication model on the server. Add a dedicated Studio runtime watch script that rebuilds the published runtime artifacts on source changes and run it alongside the existing Studio TypeScript watcher in `packages/studio` dev mode.
+
+**Tech Stack:** Bun, Nx inferred `dev` targets, Node/Bun filesystem watching, node:test, Prettier
+
+---
+
+### Task 1: Spec And Watcher Contract
+
+**Files:**
+
+- Modify: `docs/specs/SPEC-011-local-development-and-operations.md`
+- Create: `docs/plans/2026-03-26-compose-dev-studio-runtime-watch.md`
+
+**Step 1:** Add the explicit `docker-compose.dev.yml` watcher contract to `SPEC-011`.
+
+**Step 2:** Keep the plan local-only and out of the commit.
+
+### Task 2: Regression Test
+
+**Files:**
+
+- Create: `packages/studio/src/lib/dev-runtime-watch.test.ts`
+- Modify: `packages/studio/package.json`
+
+**Step 1:** Write a failing test that asserts the Studio `dev` script runs both the existing TypeScript watch and the new runtime artifact watcher.
+
+**Step 2:** Run only that test and confirm it fails because the current script only runs `tsc --watch`.
+
+### Task 3: Runtime Watcher
+
+**Files:**
+
+- Create: `packages/studio/src/lib/dev-runtime-watch.ts`
+- Modify: `packages/studio/package.json`
+
+**Step 1:** Implement a small Bun/Node watcher that watches `packages/studio/src/**`, debounces rapid changes, and reruns `buildStudioRuntimeArtifacts()`.
+
+**Step 2:** Keep the watcher log output actionable and non-spammy.
+
+**Step 3:** Update the Studio `dev` script to run both the TypeScript watch and the runtime watcher in one long-lived process.
+
+### Task 4: Documentation And Verification
+
+**Files:**
+
+- Modify: `apps/studio-example/README.md`
+
+**Step 1:** Update the local-dev docs so the watcher behavior matches the spec.
+
+**Step 2:** Run the focused watcher test.
+
+**Step 3:** Run `bun run format:check` and `bun run check`.

+# Studio Example MDX Demo Components Design
+
+Date: 2026-03-26
+Scope: register example local MDX components in `apps/studio-example` for Studio editor testing
+
+## Notes
+
+- This design doc is intentionally local-only under `docs/plans/` per repo workflow.
+- The owning spec is [SPEC-007](../specs/SPEC-007-editor-mdx-and-collaboration.md).
+- No spec delta is required. This work stays inside the existing local MDX component registration and prepared-catalog contract.
+
+## Spec Delta Summary
+
+1. No new spec text is needed.
+2. The affected behavior is the demo host app's local MDX component registration and how the embedded Studio route receives that prepared config.
+3. Acceptance depends on the existing `SPEC-007` sections covering:
+   - `config.components` as the source of truth
+   - host-local `load` and `loadPropsEditor` callbacks
+   - node-side prop extraction through `prepareStudioConfig(...)`
+   - local runtime preview and custom props editor resolution keyed by component name
+
+## Current State
+
+`apps/studio-example` currently exposes Studio through:
+
+- [apps/studio-example/app/admin/[[...path]]/page.tsx](../../apps/studio-example/app/admin/[[...path]]/page.tsx)
+- [apps/studio-example/app/admin/admin-studio-client.tsx](../../apps/studio-example/app/admin/admin-studio-client.tsx)
+
+The app's [mdcms.config.ts](../../apps/studio-example/mdcms.config.ts) currently defines only content types and environment metadata. It does not register any local MDX components.
+
+The admin route currently passes `createStudioEmbedConfig(config)` into `Studio`. That helper intentionally strips local MDX component registrations and loader callbacks, so simply adding components to `mdcms.config.ts` would not make them available to the current sample admin surface.
+
+The `/demo/content` routes intentionally render raw API payloads and raw body text. They are not part of this change.
+
+## Decision
+
+Implement a realistic host-app MDX demo surface for editor testing by:
+
+1. registering three example components in `apps/studio-example/mdcms.config.ts`
+2. adding the component modules and one custom props editor inside the sample app
+3. switching the admin route from embed-only config to `prepareStudioConfig(...)`
+
+The demo renderer remains raw-content only. This task is about validating Studio/editor integration, not front-end page rendering.
+
+## Approved Component Set
+
+### Chart
+
+- self-closing component
+- exercises void insertion
+- exercises auto-form editing
+- props:
+  - `data: number[]`
+  - `type: "bar" | "line" | "pie"`
+  - `title?: string`
+  - `color?: string`
+
+### Callout
+
+- wrapper component
+- exercises nested rich-text editing inside the editor canvas
+- props:
+  - `tone: "info" | "warning" | "success"`
+  - `title?: string`
+  - `children`
+
+### PricingTable
+
+- self-closing component
+- exercises custom props editor loading
+- props:
+  - `title?: string`
+  - `tiers: Array<{ name: string; price: string; description?: string }>`
+- edited through `PricingTable.editor.tsx` instead of auto-generated controls
+
+## Architecture
+
+### 1. Config-owned registration
+
+The sample host app continues to use `mdcms.config.ts` as the source of truth. The new `components` array will register:
+
+- `name`
+- `importPath`
+- `description`
+- `load`
+- `propHints` where useful
+- `propsEditor` and `loadPropsEditor` for `PricingTable`
+
+Because `apps/studio-example` does not currently define an `@/` path alias, the sample registrations should use plain relative import paths rather than introducing unrelated alias infrastructure.
+
+### 2. Prepared config on the admin route
+
+The admin route will prepare the authored config on the server with `prepareStudioConfig(...)` before passing it into the client `Studio` mount.
+
+This is the key integration change. It ensures the embedded Studio runtime receives:
+
+- serializable extracted prop metadata
+- catalog metadata for insertion and props-panel display
+- executable local preview loaders and custom-editor loaders through the config-owned runtime path
+
+The route must fail closed if preparation fails, rather than silently launching Studio without the registered components.
+
+### 3. No document-renderer changes
+
+The raw `/demo/content` pages stay untouched. They intentionally display API payloads and the stored document body text. They do not need to render MDX components for this testing slice.
+
+## UI and Data Flow
+
+1. The host app registers `Chart`, `Callout`, and `PricingTable` in `mdcms.config.ts`.
+2. The admin route calls `prepareStudioConfig(config, { cwd, tsconfigPath? })`.
+3. `prepareStudioConfig(...)` resolves component source files, extracts supported props, and preserves valid `propHints`.
+4. The prepared config is passed to `Studio`.
+5. Studio derives the local MDX catalog and host bridge from the prepared config.
+6. Editors can insert the example components through the CMS-74 toolbar and slash-command entrypoints.
+7. The props panel and preview path behave according to each component kind:
+   - `Chart` -> auto-form + preview
+   - `Callout` -> wrapper content + preview, no props-panel editing for `children`
+   - `PricingTable` -> custom props editor + preview
+
+## Error Handling
+
+- Invalid component import paths fail the admin route during preparation.
+- Invalid prop hints fail preparation instead of being ignored in the browser.
+- Missing custom props editor resolution continues to fall back to auto-form behavior where the Studio runtime already supports it.
+- Components with no editable extracted props continue to use the existing empty/custom panel states. No demo-only fallback logic is added.
+
+## Testing Strategy
+
+Add the narrowest tests that prove the sample host registration is wired correctly:
+
+- config-level coverage for the registered component names and loaders
+- admin-route coverage for using prepared config rather than stripped embed-only config
+- keep broader editor behavior coverage in `@mdcms/studio`, which already owns those contracts
+
+Verification should include:
+
+- focused tests added for the sample app integration
+- `bun nx build studio-example`
+- `bun nx typecheck studio-example`
+- workspace-required `bun run format:check`
+- workspace-required `bun run check`
+
+## Documentation
+
+Update [apps/studio-example/README.md](../../apps/studio-example/README.md) to explain that:
+
+- the sample app now registers local MDX components for Studio testing
+- the admin route uses prepared config so local catalog metadata reaches Studio
+- the `/demo/content` routes remain raw-content inspection surfaces
+
+## Scope Boundaries
+
+In scope:
+
+- demo-host MDX component files
+- config registration for three example components
+- one example custom props editor
+- admin route wiring to `prepareStudioConfig(...)`
+- sample-app README updates
+
+Out of scope:
+
+- rendering MDX on `/demo/content`
+- backend API changes
+- new path-alias infrastructure
+- changes to the core Studio MDX component contract

+# Studio Example MDX Demo Components Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Register `Chart`, `Callout`, and `PricingTable` in `apps/studio-example` so the sample admin Studio route can exercise local MDX insertion, preview, auto-form editing, wrapper editing, and custom props editor loading through the real prepared-config path.
+
+**Architecture:** Keep `apps/studio-example/mdcms.config.ts` as the source of truth for local MDX component registration. Add the example component modules inside the sample app, prepare the full config on the admin server route with `prepareStudioConfig(...)`, and document that the raw `/demo/content` pages remain renderer-free inspection surfaces.
+
+**Tech Stack:** Bun, Nx, TypeScript, React 19, Next.js 15, node:test, react-dom/server
+
+---
+
+### Task 1: Add demo-host MDX component registrations and component modules
+
+**Files:**
+
+- Create: `apps/studio-example/components/mdx/Chart.tsx`
+- Create: `apps/studio-example/components/mdx/Callout.tsx`
+- Create: `apps/studio-example/components/mdx/PricingTable.tsx`
+- Create: `apps/studio-example/components/mdx/PricingTable.editor.tsx`
+- Modify: `apps/studio-example/mdcms.config.ts`
+- Test: `apps/studio-example/mdcms.config.test.ts`
+
+**Step 1: Write the failing test**
+
+Add a config test that imports `apps/studio-example/mdcms.config.ts` and asserts:
+
+- `config.components` exists
+- registered component names are exactly `Chart`, `Callout`, and `PricingTable`
+- `PricingTable` includes `propsEditor` and `loadPropsEditor`
+- `Chart` includes a `color` prop hint suitable for the auto-form demo
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test apps/studio-example/mdcms.config.test.ts`
+Expected: FAIL because the test file and component registrations do not exist yet.
+
+**Step 3: Write minimal implementation**
+
+Implement:
+
+- lightweight presentational sample components
+- a simple `PricingTable` custom editor using `PropsEditorComponent`
+- `mdcms.config.ts` component registrations with relative `importPath` values and local loader callbacks
+
+Example registration shape:
+
+```ts
+{
+  name: "Chart",
+  importPath: "./components/mdx/Chart",
+  description: "Render a small chart card in MDX content.",
+  load: () => import("./components/mdx/Chart").then((m) => m.Chart),
+  propHints: {
+    color: { widget: "color-picker" },
+  },
+}
+```
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test apps/studio-example/mdcms.config.test.ts`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add apps/studio-example/components/mdx/Chart.tsx apps/studio-example/components/mdx/Callout.tsx apps/studio-example/components/mdx/PricingTable.tsx apps/studio-example/components/mdx/PricingTable.editor.tsx apps/studio-example/mdcms.config.ts apps/studio-example/mdcms.config.test.ts
+git commit -m "feat(studio-example): register mdx demo components"
+```
+
+### Task 2: Switch the sample admin route to prepared Studio config
+
+**Files:**
+
+- Modify: `apps/studio-example/app/admin/[[...path]]/page.tsx`
+- Modify: `apps/studio-example/app/admin/admin-studio-client.tsx`
+- Test: `apps/studio-example/app/admin/[[...path]]/page.test.tsx`
+
+**Step 1: Write the failing test**
+
+Add a narrow route test that proves the admin page no longer passes `createStudioEmbedConfig(config)` and instead provides a config object that still includes the registered MDX components.
+
+The test can import the default page function, render or inspect its returned element tree, and assert that the `config` prop handed to `AdminStudioClient` contains `components`.
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test 'apps/studio-example/app/admin/[[...path]]/page.test.tsx'`
+Expected: FAIL because the route still strips component registrations through `createStudioEmbedConfig(...)`.
+
+**Step 3: Write minimal implementation**
+
+Implement:
+
+- server-side `prepareStudioConfig(...)` usage in the admin page
+- `cwd` and `tsconfigPath` arguments that resolve correctly from `apps/studio-example`
+- any small prop-type adjustments needed in `AdminStudioClient`
+
+Example route shape:
+
+```tsx
+const preparedConfig = await prepareStudioConfig(config, {
+  cwd: process.cwd(),
+  tsconfigPath: join(process.cwd(), "apps/studio-example/tsconfig.json"),

+
+### Task 3: Document the sample-app behavior
+
+**Files:**
+
+- Modify: `apps/studio-example/README.md`
+
+**Step 1: Write the failing test**
+
+Skip. This task is documentation-only.
+
+**Step 2: Run test to verify it fails**
+
+Skip. No behavior assertion is needed beyond the focused tests in Tasks 1-2.
+
+**Step 3: Write minimal implementation**
+
+Update the README to explain:
+
+- the sample app now registers `Chart`, `Callout`, and `PricingTable`
+- the admin route uses prepared config so Studio receives local MDX metadata
+- the `/demo/content` pages still show raw content and do not render MDX
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test apps/studio-example`
+Expected: PASS for the focused sample-app tests added earlier.
+
+**Step 5: Commit**
+
+```bash
+git add apps/studio-example/README.md
+git commit -m "docs(studio-example): document mdx demo components"
+```
+
+### Task 4: Final verification

+**Files:**
+
+- Verify only
+
+**Step 1: Run focused sample-app tests**
+
+Run: `bun test apps/studio-example`
+Expected: PASS

+# CMS-56 + CMS-133 Editor Publish Integration Design
+
+Date: 2026-03-27
+Tasks:
+
+- `CMS-56 - Wire Studio publish flow + version history panel + version diff view`
+- `CMS-133 - Integrate editor draft load/save flow with real content mutations`
+
+## Notes
+
+- This design doc is intentionally local-only under `docs/plans/` per repo workflow.
+- The owning specs are:
+  - [SPEC-003](../specs/SPEC-003-content-storage-versioning-and-migrations.md)
+  - [SPEC-004](../specs/SPEC-004-schema-system-and-sync.md)
+  - [SPEC-005](../specs/SPEC-005-auth-authorization-and-request-routing.md)
+  - [SPEC-007](../specs/SPEC-007-editor-mdx-and-collaboration.md)
+- No spec delta is required before implementation. The current spec set already defines the route behavior, auth mode, write guard, publish semantics, version-history contract, and version-detail reads needed for this slice.
+
+## Spec Delta Summary
+
+1. No spec text changes are required.
+2. The affected behavior is the Studio document editor route:
+   - draft document load
+   - draft update mutation
+   - publish flow with optional change summary
+   - version history display
+   - version diff between any two selected immutable snapshots
+3. Acceptance criteria depend on existing spec text for:
+   - `GET /api/v1/content/:documentId?draft=true`
+   - `PUT /api/v1/content/:documentId`
+   - `POST /api/v1/content/:documentId/publish`
+   - `GET /api/v1/content/:documentId/versions`
+   - `GET /api/v1/content/:documentId/versions/:version`
+   - schema-hash write enforcement on content writes
+   - session-authenticated CSRF bootstrap via `GET /api/v1/auth/session`
+
+## Current State
+
+The repo already contains the backend contracts required for this work:
+
+- `apps/server/src/lib/content-api/routes.ts`
+  - content read, update, publish, version summary, and version detail routes
+- `apps/server/src/lib/auth.ts`
+  - session route returning `csrfToken`
+  - CSRF protection for state-changing session requests
+  - RBAC checks for draft reads and publish operations
+- `packages/shared/src/lib/contracts/content-api.ts`
+  - shared version summary and version detail response shapes
+- `packages/studio/src/lib/document-shell.ts`
+  - draft document load helper with scoped headers and typed error states
+
+The gap is entirely on the Studio route side:
+
+- `packages/studio/src/lib/runtime-ui/pages/content-document-page.tsx`
+  - still reads from `mockDocuments`
+  - simulates publish locally
+  - has no real version history or diff state
+- `packages/studio/src/lib/runtime-ui/components/editor/editor-sidebar.tsx`
+  - still exposes mock field-editing controls that are not backed by schema-aware real mutations
+- there is no Studio-side helper for:
+  - CSRF bootstrap
+  - schema-hash derivation from local config
+  - real draft update mutation
+  - publish mutation
+  - version history fetch
+  - version diff construction
+
+## Decision
+
+Implement one dedicated Studio document-route data layer inside `packages/studio` and keep the route component mostly presentational.
+
+Do not add new backend endpoints.
+
+Do not turn this into a generic Studio-wide query framework.
+
+## Architecture
+
+### 1. Route-local data layer
+
+Add a typed Studio-side helper module responsible for:
+
+- bootstrapping CSRF for cookie-authenticated mutations through `GET /api/v1/auth/session`
+- loading the routed draft document
+- updating the draft document through `PUT /api/v1/content/:documentId`
+- publishing through `POST /api/v1/content/:documentId/publish`
+- loading version summaries and specific version snapshots
+- normalizing error handling into route-friendly states
+
+This keeps request details out of the page component and provides one reuse point for later `CMS-57` write gating.
+
+### 2. Local schema-hash derivation
+
+Draft writes must satisfy the `x-mdcms-schema-hash` contract from `SPEC-004`.
+
+The Studio route should derive the local schema hash from the full `MdcmsConfig` already accepted by `@mdcms/studio` when the host passes the authored config object instead of the shell-only embed config.
+
+The derivation should mirror the existing server-side demo-seed hashing inputs:
+
+- normalized raw config snapshot
+- resolved environment schema
+- active environment name
+
+If the route only receives shell-only config and cannot derive a trustworthy local schema hash, draft writes and publish must remain disabled with truthful copy. Reads still work.
+
+### 3. Truthful editor-route behavior
+
+The document route should stop pretending unfinished UI is live.
+
+That means:
+
+- keep real draft loading and body persistence in scope
+- keep real publish/history/diff in scope
+- remove or disable mock controls that imply unavailable schema-driven field editing
+- do not ship a fake locale switcher; locale-variant behavior remains owned by `CMS-63`
+- do not expand into schema-mismatch recovery UI; guarded write-mode belongs to `CMS-57`
+
+### 4. Publish and history model
+
+Publish remains explicit and versioned:
+
+- the publish dialog keeps the optional change-summary textarea
+- success refreshes the route document state and version history
+- version history lists:
+  - version
+  - `publishedBy`
+  - `publishedAt`
+  - `changeSummary`
+
+The history panel is read-only in this slice. Restore stays out of scope.
+
+### 5. Client-side diff model
+
+There is no spec-owned diff endpoint, so diff must be computed client-side from two fetched immutable version snapshots.
+
+The diff view should support any two selected versions, not only adjacent pairs.
+
+The comparison should cover:
+
+- path changes
+- frontmatter changes
+- body changes
+
+The implementation can stay simple and readable. It does not need a full word-level rich diff engine to satisfy the current spec.
+
+## UI Behavior
+
+### Document route lifecycle
+
+The route must render complete UI states for:
+
+- loading
+- ready
+- not found
+- forbidden
+- generic load error
+
+The page should continue to preserve route context (`type`, `documentId`) even when the content load fails.
+
+### Draft save behavior
+
+Draft updates are debounced from the editor route:
+
+- editing marks the route dirty immediately
+- a debounce triggers the real update mutation
+- save states are visible:
+  - `unsaved`
+  - `saving`
+  - `saved`
+  - `save failed`
+
+The page owns the canonical draft snapshot after each successful mutation so subsequent publish/history refreshes use real backend state.
+
+### Publish behavior
+
+- the Publish button opens the dialog
+- the dialog sends optional `changeSummary`
+- success closes the dialog, refreshes the current draft snapshot, and refreshes version history
+- forbidden or mutation failures surface inline route-level feedback
+
+### Version history and diff behavior
+
+- the route exposes a real version history panel
+- the panel supports:
+  - loading
+  - empty
+  - error
+  - populated
+- the user can select any two versions for comparison
+- selecting a version pair fetches the two immutable snapshots and renders the diff view
+
+## Testing Strategy
+
+### Studio helper tests
+
+Add focused tests for:
+
+- draft load
+- cookie-auth CSRF bootstrap
+- token-auth mutation path without CSRF bootstrap
+- schema-hash derivation
+- publish request payloads
+- version list/detail fetch behavior
+- typed error normalization
+
+### Route integration tests
+
+Add route-level tests covering:
+
+- loading -> ready flow
+- `FORBIDDEN`
+- `NOT_FOUND`
+- draft save success and failure
+- publish success and error
+- version history states
+- arbitrary-version diff selection
+- write-disabled state when schema-hash-capable config is unavailable
+
+### Existing regression coverage
+
+Keep existing tests green in:
+
+- `packages/studio`
+- touched shared helpers, if any
+- touched server packages, if any server change becomes necessary
+
+## Scope Boundaries
+
+In scope:
+
+- real draft document load for the routed editor
+- real draft body save
+- real publish flow
+- real version history panel
+- real version diff view
+- truthful editor-route control availability
+- package README updates for write-enabled config requirements
+
+Out of scope:
+
+- restore from version history
+- unpublish workflow unless needed to remove a misleading mock control
+- locale variant switching
+- schema mismatch banner and read-only recovery flow
+- schema browsing
+- environment-specific field badges
+- generalized Studio query/mutation framework
+- Post-MVP autosave durability behavior such as blur/disconnect flush and collaboration hooks

+# CMS-56 + CMS-133 Editor Publish Integration Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Replace the mock Studio document route with real draft load/save behavior and wire the publish, version-history, and version-diff flows against the existing content and auth contracts.
+
+**Architecture:** Keep the server contracts unchanged and add a document-route data layer inside `@mdcms/studio` that owns CSRF bootstrap, local schema-hash derivation, content mutations, version reads, and diff construction. The route page becomes a thin stateful container over that helper layer, while existing editor components continue to focus on markdown editing and MDX behavior.
+
+**Tech Stack:** Bun, Nx, TypeScript, React 19, node:test, Bun test, TipTap 3, shared MDCMS contracts
+
+---
+
+### Task 1: Add document-route API helpers for load, save, publish, and versions
+
+**Files:**
+
+- Create: `packages/studio/src/lib/document-route-api.ts`
+- Test: `packages/studio/src/lib/document-route-api.test.ts`
+- Modify: `packages/studio/src/lib/document-shell.ts`
+- Modify: `packages/studio/src/lib/request-auth.ts`
+
+**Step 1: Write the failing test**
+
+Add tests that prove:
+
+- draft document reads send scoped headers and `draft=true`
+- cookie-authenticated mutations fetch CSRF from `GET /api/v1/auth/session`
+- token-authenticated mutations do not require CSRF bootstrap
+- publish sends optional `changeSummary`
+- version summary/detail helpers normalize success and failure states
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test packages/studio/src/lib/document-route-api.test.ts`
+Expected: FAIL because the helper file does not exist yet.
+
+**Step 3: Write minimal implementation**
+
+Implement one helper module that exposes:
+
+- draft load
+- session CSRF bootstrap
+- draft update
+- publish
+- version summary list
+- version detail fetch
+
+Reuse existing auth header logic instead of duplicating request-init behavior.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test packages/studio/src/lib/document-route-api.test.ts`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/studio/src/lib/document-route-api.ts packages/studio/src/lib/document-route-api.test.ts packages/studio/src/lib/document-shell.ts packages/studio/src/lib/request-auth.ts
+git commit -m "feat(studio): add document route api helpers"
+```
+
+### Task 2: Add local schema-hash derivation and write-capability gating
+
+**Files:**
+
+- Create: `packages/studio/src/lib/document-route-schema.ts`
+- Test: `packages/studio/src/lib/document-route-schema.test.ts`
+- Modify: `packages/studio/src/lib/studio.ts`
+- Modify: `packages/studio/src/index.ts`
+
+**Step 1: Write the failing test**
+
+Add tests that prove:
+
+- full authored Studio config can produce a deterministic local schema hash for the active environment
+- shell-only config cannot produce a write-capable schema hash result
+- the hash inputs remain stable for equivalent config data
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test packages/studio/src/lib/document-route-schema.test.ts`
+Expected: FAIL because the schema-hash helper does not exist yet.
+
+**Step 3: Write minimal implementation**
+
+Implement:
+
+- normalized raw config snapshot builder
+- environment schema serialization using shared config/schema helpers
+- deterministic SHA-256 hash generation
+- one route-facing capability result that says whether writes are allowed and why not
+
+Do not add new public server contracts.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test packages/studio/src/lib/document-route-schema.test.ts`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash

+git commit -m "feat(studio): derive local schema hash for editor writes"
+```
+
+### Task 3: Add client-side version diff helpers
+
+**Files:**
+
+- Create: `packages/studio/src/lib/document-version-diff.ts`
+- Test: `packages/studio/src/lib/document-version-diff.test.ts`
+
+**Step 1: Write the failing test**
+
+Add tests that prove:
+
+- diff construction compares any two selected versions, not just adjacent ones
+- path changes are surfaced
+- frontmatter differences are surfaced
+- body line differences are surfaced deterministically
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test packages/studio/src/lib/document-version-diff.test.ts`
+Expected: FAIL because the diff helper does not exist yet.
+
+**Step 3: Write minimal implementation**
+
+Implement one small, readable diff helper that accepts two immutable version snapshots and returns structured sections for:
+
+- path
+- frontmatter
+- body
+
+Keep the implementation intentionally simple and dependency-light.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test packages/studio/src/lib/document-version-diff.test.ts`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/studio/src/lib/document-version-diff.ts packages/studio/src/lib/document-version-diff.test.ts
+git commit -m "feat(studio): add document version diff helper"
+```
+
+### Task 4: Replace mock document-route state with real draft load and save behavior
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/runtime-ui/pages/content-document-page.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx`
+- Modify: `packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.tsx`
+- Modify: `packages/studio/src/lib/remote-studio-app.test.ts`
+
+**Step 1: Write the failing test**
+
+Add tests that prove:
+
+- the page renders loading, ready, forbidden, not-found, and generic error states from real helper results
+- editor changes move through unsaved -> saving -> saved
+- failed save surfaces mutation feedback without pretending the draft persisted
+- write actions are disabled when local schema-hash capability is unavailable
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx packages/studio/src/lib/remote-studio-app.test.ts`
+Expected: FAIL because the route still reads from mock data.
+
+**Step 3: Write minimal implementation**
+
+Refactor the route so it:
+
+- loads the routed draft document through the new helper layer
+- owns debounced draft persistence
+- updates save-state labels from real request outcomes
+- keeps route context intact on failure
+
+Do not widen the editor component into a data-fetching surface.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx packages/studio/src/lib/remote-studio-app.test.ts`
+Expected: PASS
+
+**Step 5: Commit**
+
+```bash

+git commit -m "feat(studio): wire real draft load and save on editor route"
+```
+
+### Task 5: Wire publish, version history, and arbitrary-version diff UI
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/runtime-ui/pages/content-document-page.tsx`
+- Modify: `packages/studio/src/lib/runtime-ui/components/editor/editor-sidebar.tsx`
+- Modify: `packages/studio/src/lib/runtime-ui/components/ui/dialog.tsx`
+- Modify: `packages/studio/src/lib/runtime-ui/components/ui/tabs.tsx`
+- Test: `packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx`
+
+**Step 1: Write the failing test**
+
+Add tests that prove:
+
+- publish opens the dialog, submits optional change summary, and refreshes route state on success
+- version history renders loading, empty, error, and populated states
+- the version panel shows version, `publishedBy`, `publishedAt`, and `changeSummary`
+- diff selection can compare any two chosen versions
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx`
+Expected: FAIL because publish/history/diff are still mock-only or absent.
+
+**Step 3: Write minimal implementation**
+
+Implement:
+
+- real publish dialog submit
+- route-level mutation feedback
+- real version history panel
+- arbitrary-version selection controls
+- diff rendering using the new helper
+
+Keep restore and unpublish out of scope unless one of them must be hidden to keep the page truthful.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx`
+Expected: PASS
+
+**Step 5: Commit**

+- Modify: `packages/studio/src/lib/runtime-ui/components/editor/editor-sidebar.tsx`
+- Modify: `packages/studio/src/lib/runtime-ui/pages/content-document-page.tsx`
+- Modify: `packages/studio/README.md`
+
+**Step 1: Write the failing test**
+
+Add or update the narrowest UI assertion needed to prove:
+
+- mock-only field editors, fake locale switching, or other unfinished controls are hidden or truthfully disabled
+- route copy reflects the new write-capability requirement
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx packages/studio/src/lib/remote-studio-app.test.ts`
+Expected: FAIL because the page still exposes misleading controls.
+
+**Step 3: Write minimal implementation**
+
+Update the UI and docs so that:
+
+- unsupported controls are removed or explicitly disabled with truthful messaging
+- the README explains that write-enabled editor routes require full config data capable of local schema-hash derivation
+- concise inline comments explain any non-obvious capability gating
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx packages/studio/src/lib/remote-studio-app.test.ts`
+Expected: PASS
+
+**Step 5: Commit**

+- Verify only
+
+**Step 1: Run focused Studio tests**
+
+Run: `bun test packages/studio/src`
+Expected: PASS
+

+
+Run: `bun nx build studio && bun nx typecheck studio`
+Expected: PASS
+
+**Step 3: Run repo-required baseline checks**
+
+Run: `bun run format:check && bun run check`
+Expected: PASS
+
+**Step 4: Confirm local-only paths remain unstaged**
+
+Run: `git status --short`
+Expected:
+
+- `docs/plans/` remains local-only and unstaged
+- `ROADMAP_TASKS.md`, `AGENTS.md`, and other local-only files remain unstaged
+
+**Step 5: Capture any residual risk**
+
+Record any remaining gaps only if verification reveals them. Do not silently broaden scope into `CMS-57`, `CMS-63`, or restore/unpublish follow-up work.

+# Studio Example SDK Content Demo Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add a parallel SDK-backed content demo to the example app while preserving the existing raw content API inspection routes, and make the distinction obvious in navigation and page copy.
+
+**Architecture:** Keep `/demo/content*` as the direct-fetch raw API surface. Add `/demo/sdk-content*` routes that use `@mdcms/sdk` with the same configured project/environment scope and demo API key. Improve cross-linking and explicit "Data source" labels so developers can compare the raw API and SDK surfaces without ambiguity.
+
+**Tech Stack:** Next.js app routes, React server components, `@mdcms/sdk`, Bun workspace dependencies, node:test assertions for lightweight page tests.
+
+---
+
+### Task 1: Capture the route split in the example app shell
+
+**Files:**
+
+- Modify: `apps/studio-example/app/page.tsx`
+- Modify: `apps/studio-example/README.md`
+
+**Step 1: Add the new demo route entry point**
+
+Update the host app landing page so it links to both `/demo/content` and `/demo/sdk-content`.
+
+**Step 2: Clarify route ownership in docs**
+
+Update the example app README route list and runbook text so raw API pages and SDK pages are both documented, with explicit notes about their data sources.
+
+### Task 2: Add focused tests for the new demo distinction
+
+**Files:**
+
+- Create: `apps/studio-example/app/demo/sdk-content/page.test.tsx`
+- Create: `apps/studio-example/app/demo/sdk-content/[documentId]/page.test.tsx`
+- Modify: `apps/studio-example/app/page.tsx`
+
+**Step 1: Write a failing list-page test**
+
+Add a lightweight page test that asserts the SDK list page renders an SDK-specific heading or data-source label and links back to the raw surface.
+
+**Step 2: Write a failing detail-page test**
+
+Add a lightweight page test that asserts the SDK detail page renders an SDK-specific heading or data-source label and links back to the SDK list and raw detail/list surfaces as appropriate.
+
+**Step 3: Run the focused tests to confirm failure**
+
+Run the new page tests directly with Bun.
+
+### Task 3: Implement the SDK-backed demo routes
+
+**Files:**
+
+- Create: `apps/studio-example/app/demo/sdk-content/page.tsx`
+- Create: `apps/studio-example/app/demo/sdk-content/[documentId]/page.tsx`
+- Create: `apps/studio-example/app/demo/sdk-content/sdk-demo-client.ts`
+- Modify: `apps/studio-example/package.json`
+
+**Step 1: Add the SDK dependency**
+
+Add `@mdcms/sdk` to the example app package so the demo routes can consume the published package boundary directly.
+
+**Step 2: Centralize SDK client creation**
+
+Create a small server-only helper that reads `mdcms.config.ts`, injects the optional `MDCMS_DEMO_API_KEY`, and returns `createClient(...)`.
+
+**Step 3: Implement the SDK list page**
+
+Render the same content summary shape as the raw page, but fetch through `client.list(...)`. Add explicit labeling that the page is using `@mdcms/sdk`.
+
+**Step 4: Implement the SDK detail page**
+
+Fetch by document ID through `client.get(...)`, render the same raw body/frontmatter presentation, and include explicit data-source labeling plus navigation between raw and SDK views.
+
+### Task 4: Tighten the raw pages and shared navigation copy
+
+**Files:**
+
+- Modify: `apps/studio-example/app/demo/content/page.tsx`
+- Modify: `apps/studio-example/app/demo/content/[documentId]/page.tsx`
+
+**Step 1: Add explicit raw-API labeling**
+
+Keep the raw routes as-is functionally, but make the page titles and copy explicitly say "Raw Content API".
+
+**Step 2: Cross-link the raw and SDK views**
+
+Add links on each raw page to the corresponding SDK surface so comparison is one click away.
+
+### Task 5: Verify and document
+
+**Files:**
+
+- Modify: `apps/studio-example/README.md`
+
+**Step 1: Update the runbook**
+
+Point the demo verification section at both surfaces and describe what each one demonstrates.
+
+**Step 2: Run focused verification**
+
+Run targeted `bun test` commands for the new page tests, then `bun run format:check`, then `bun run check`.
+
+**Step 3: Leave local-only planning files uncommitted**
+
+Do not stage anything under `docs/plans/`.

+# SDK Post-MVP Epic Design
+
+**Date:** 2026-03-31
+
+## Goal
+
+Capture the approved post-MVP SDK backlog split so Jira can reflect clear SDK ownership without expanding MVP scope.
+
+## Decisions
+
+- MVP SDK remains read-only.
+- Strong SDK type safety is desired, but it is post-MVP.
+- Full SDK mutations are also post-MVP.
+- Type safety should be schema-derived rather than based on user-authored types.
+
+## Epic Split
+
+### SDK Type System & Query Surface
+
+Owns schema-derived type generation and the typed read/query experience:
+
+- generated content type map from schema artifacts
+- typed `get` / `list`
+- typed filter and sort inputs
+- typed `resolve` path support
+- cursor pagination support in the SDK query surface
+- typed read docs, examples, and contract coverage
+
+### SDK Mutations & Write Safety
+
+Owns direct SDK write flows and the compatibility boundary around writes:
+
+- SDK write contract/spec work after schema-hash pinning is resolved
+- local schema-hash artifact flow for SDK write clients
+- create / update mutations
+- delete / restore mutations
+- publish / unpublish mutations
+- version history / restore helpers
+- deterministic mutation error taxonomy
+- write docs, examples, and compatibility coverage
+
+## Dependency Notes
+
+- `CMS-147` remains the architecture input for SDK write safety and should not be moved until the spike is complete.
+- `CMS-100` remains under `Search`.
+- `CMS-908` should move under `SDK Type System & Query Surface` because it is SDK query-surface work.
+- SDK write implementation tasks must depend on the post-`CMS-147` write contract/spec task.

+# Studio Schema Guard And Read-Only Browser Design
+
+Date: 2026-03-31
+
+## Goal
+
+Implement a combined Studio slice that:
+
+- blocks document writes when the local Studio schema hash does not match the synced server schema hash
+- lets privileged users run an explicit `Sync Schema` recovery action
+- replaces the placeholder `/admin/schema` surface with a live read-only schema browser
+
+This design intentionally combines the schema mismatch guard and read-only schema browsing work while excluding the broader Settings MVP cleanup.
+
+## Scope
+
+Included:
+
+- live schema fetch for the active `(project, environment)` target
+- local-versus-server schema hash comparison
+- guarded read-only editor mode while mismatch is unresolved
+- explicit privileged `Sync Schema` action backed by `PUT /api/v1/schema`
+- live read-only schema browser UI for `/admin/schema`
+- minimal Settings integration that reuses or points to the shared schema browser path
+
+Excluded:
+
+- broad Settings tab cleanup and truthful-control audit
+- new client-side auth/session contracts for role exposure
+- manual schema editing controls in Studio
+
+## Contract Basis
+
+The behavior is already specified by:
+
+- `docs/specs/SPEC-004-schema-system-and-sync.md`
+- `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
+- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+
+The design relies on existing server behavior:
+
+- `GET /api/v1/schema` for read-only schema browsing
+- `PUT /api/v1/schema` for privileged explicit sync
+- content write rejection when `x-mdcms-schema-hash` is missing or mismatched
+
+## Architecture
+
+Add one Studio-side schema state path in `packages/studio/src/lib` that:
+
+1. fetches the current schema registry entries for the active target
+2. derives the local config snapshot and local schema hash from the existing Studio config capability path
+3. compares the local hash with the server hash
+4. exposes a `syncSchema()` action that forwards the local snapshot to `PUT /api/v1/schema`
+
+That state becomes the shared source for:
+
+- `/admin/schema` read-only schema browsing
+- document editor write gating and mismatch recovery
+
+The client should not gain a new role contract in this slice. Capability is derived from endpoint behavior:
+
+- `GET /schema` success means schema browsing is available
+- `PUT /schema` success means the current user can perform privileged sync
+- `403` on sync means the user remains in read-only recovery without the action
+
+## Components And Data Flow
+
+### Schema Adapter
+
+Create a Studio adapter beside the existing action and document adapters that wraps:
+
+- `GET /api/v1/schema`
+- `PUT /api/v1/schema`
+
+The adapter applies:
+
+- Studio auth mode (`cookie` or `token`)
+- target headers: `X-MDCMS-Project`, `X-MDCMS-Environment`
+- CSRF bootstrap for session-authenticated writes before `PUT /schema`
+
+### Shared Schema State
+
+Add a shared state module or hook that normalizes:
+
+- `loading`
+- `ready`
+- `empty`
+- `forbidden`
+- `error`
+
+and derives:
+
+- `localSchemaHash`
+- `serverSchemaHash`
+- `isMismatch`
+- `canSync`
+- `syncStatus`
+
+It should expose:
+
+- schema entries
+- reload
+- sync action
+- deterministic error metadata
+
+### Schema Browser UI
+
+Replace `/admin/schema` with a real read-only browser backed by live schema entries.
+
+The page should:
+
+- render content types, fields, localization, and validator metadata from `resolvedSchema`
+- never expose schema edit controls
+- show loading, empty, forbidden, and generic error states
+- surface the same mismatch banner and privileged recovery action when applicable
+
+### Document Editor Guard
+
+The document route should consume the shared schema state and enter guarded read-only mode when:
+
+- the local schema is unavailable, or
+- the local and server schema hashes do not match
+
+In guarded read-only mode:
+
+- the editor remains readable
+- draft save and publish actions are disabled
+- the page shows an explanatory banner
+- privileged users can run `Sync Schema`
+- non-privileged users see recovery guidance only
+
+## Error Handling
+
+### Loading
+
+Before schema state resolves, Studio should keep guarded write actions disabled rather than briefly enabling them.
+
+### Forbidden
+
+If `GET /api/v1/schema` returns `403`, the schema page shows a forbidden state. If a user can read content but cannot sync schema, the document page still stays read-only when mismatch is detected and omits the privileged action.
+
+### Sync Failure
+
+`PUT /api/v1/schema` failures should surface clearly:
+
+- `403`: sync is not permitted for this user
+- `409`: schema is incompatible and requires migration or another operator action
+- `400`: local payload/config cannot be synced as-is
+
+Write blocking remains active until the mismatch clears.
+
+### Recovery
+
+After a successful sync:
+
+- Studio reloads schema state
+- the mismatch banner clears
+- document write affordances re-enable without a full page reload
+
+## Verification
+
+Required verification should cover:
+
+- schema adapter tests for `GET /schema` and `PUT /schema`
+- schema state tests for loading, forbidden, mismatch, and sync transitions
+- schema page tests proving live read-only rendering with no edit controls
+- document page tests proving mismatch disables save and publish affordances
+- guarded-write API tests covering privileged sync and non-privileged rejection
+
+## Notes
+
+- `docs/plans` is local-only workspace documentation in this repository, so this design file is intentionally not part of the canonical committed product docs.
+- The later Settings cleanup work should stay separate. This slice should only make the minimal Settings changes needed to avoid duplicating schema UI logic.

+# Studio Schema Guard And Read-Only Browser Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add a shared Studio schema state path that powers live read-only schema browsing and guarded write-blocking recovery when the local schema hash does not match the server schema hash.
+
+**Architecture:** Reuse the existing local schema capability logic in `@mdcms/studio` to derive the local config snapshot and hash, add a dedicated schema route adapter for `GET /api/v1/schema` and `PUT /api/v1/schema`, and feed that shared state into `/admin/schema`, Settings schema access, and the document route guard. Keep auth capability inference server-driven via endpoint responses instead of adding new role data to the client session contract.
+
+**Tech Stack:** Bun, React 19, TypeScript, `@mdcms/shared` contracts, existing Studio runtime adapters, Bun test, server schema/content APIs.
+
+---
+
+### Task 1: Add Studio Schema Route Adapter
+
+**Files:**
+
+- Create: `packages/studio/src/lib/schema-route-api.ts`
+- Create: `packages/studio/src/lib/schema-route-api.test.ts`
+- Modify: `packages/studio/package.json`
+
+**Step 1: Write the failing adapter tests**
+
+Cover:
+
+- `GET /api/v1/schema` sends `X-MDCMS-Project` and `X-MDCMS-Environment`
+- cookie auth uses `credentials: "include"`
+- token auth sends `Authorization: Bearer ...`
+- `PUT /api/v1/schema` bootstraps CSRF for cookie auth, forwards the local payload, and surfaces `403` / `409` failures as runtime errors
+
+Use the existing test style from:
+
+- `packages/studio/src/lib/document-route-api.test.ts`
+- `packages/studio/src/lib/studio.test.ts`
+
+**Step 2: Run test to verify it fails**
+
+Run:
+
+```bash
+bun test packages/studio/src/lib/schema-route-api.test.ts
+```
+
+Expected:
+
+- FAIL because `schema-route-api.ts` does not exist yet
+
+**Step 3: Write minimal implementation**
+
+Implement a dedicated adapter that:
+
+- accepts `{ project, environment, serverUrl }`
+- exposes `listSchema()` and `syncSchema(payload)`
+- uses the existing `applyStudioAuthToRequestInit(...)`
+- uses `GET /api/v1/auth/session` to obtain `csrfToken` for session-authenticated sync when needed
+- validates and returns shared schema contract shapes from `@mdcms/shared`
+
+Do not export this adapter from the public package root unless a real external consumer requires it.
+
+**Step 4: Run test to verify it passes**
+
+Run:
+
+```bash
+bun test packages/studio/src/lib/schema-route-api.test.ts
+```
+
+Expected:
+
+- PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/studio/src/lib/schema-route-api.ts packages/studio/src/lib/schema-route-api.test.ts packages/studio/package.json
+git commit -m "feat(studio): add schema route adapter"
+```
+
+### Task 2: Extend Local Schema Capability Into Shared Schema State
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/document-route-schema.ts`
+- Create: `packages/studio/src/lib/schema-state.ts`
+- Create: `packages/studio/src/lib/schema-state.test.ts`
+- Modify: `packages/studio/src/lib/studio-loader.ts`
+- Modify: `packages/shared/src/lib/contracts/extensibility.ts`
+- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
+
+**Step 1: Write the failing state and contract tests**
+
+Cover:
+
+- local capability now exposes the full sync payload pieces needed by Studio: `rawConfigSnapshot`, `resolvedSchema`, and `schemaHash`
+- mount context still supports the existing document route write contract
+- shared schema state computes `isMismatch`, `canSync`, and deterministic `loading/ready/forbidden/error` states from adapter responses
+
+Use the existing fixtures in:
+
+- `packages/studio/src/lib/document-route-schema.test.ts`
+- `packages/studio/src/lib/studio-loader.test.ts`
+- `packages/shared/src/lib/contracts/extensibility.test.ts`
+
+**Step 2: Run test to verify it fails**
+
+Run:
+
+```bash
+bun test packages/studio/src/lib/document-route-schema.test.ts packages/studio/src/lib/schema-state.test.ts packages/studio/src/lib/studio-loader.test.ts packages/shared/src/lib/contracts/extensibility.test.ts
+```
+
+Expected:
+
+- FAIL because the richer capability and shared schema state do not exist yet
+
+**Step 3: Write minimal implementation**
+
+Update `resolveStudioDocumentRouteSchemaCapability(...)` so the write-enabled path includes:
+
+- `environment`
+- `rawConfigSnapshot`
+- `resolvedSchema`
+- `schemaHash`
+
+Add a new internal schema state module that:
+
+- fetches server schema entries
+- derives `serverSchemaHash` from the returned registry entries
+- compares against the local hash
+- exposes `syncSchema()` that uses the local sync payload
+
+If you must extend `StudioMountContext`, keep it narrow and internal-facing. Preserve compatibility with existing loader tests and runtime consumers.
+
+**Step 4: Run test to verify it passes**
+
+Run:
+
+```bash
+bun test packages/studio/src/lib/document-route-schema.test.ts packages/studio/src/lib/schema-state.test.ts packages/studio/src/lib/studio-loader.test.ts packages/shared/src/lib/contracts/extensibility.test.ts
+```
+
+Expected:
+
+- PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/studio/src/lib/document-route-schema.ts packages/studio/src/lib/schema-state.ts packages/studio/src/lib/schema-state.test.ts packages/studio/src/lib/studio-loader.ts packages/shared/src/lib/contracts/extensibility.ts packages/shared/src/lib/contracts/extensibility.test.ts
+git commit -m "feat(studio): add shared schema mismatch state"
+```
+
+### Task 3: Replace Placeholder Schema Page With Live Read-Only Browser
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/runtime-ui/app/admin/schema-page.tsx`
+- Create: `packages/studio/src/lib/runtime-ui/app/admin/schema-page.test.tsx`
+- Modify: `packages/studio/src/lib/remote-studio-app.tsx`
+- Modify: `packages/studio/src/lib/remote-studio-app.test.ts`
+
+**Step 1: Write the failing schema page tests**
+
+Cover:
+
+- loading, empty, forbidden, and generic error states
+- rendering of type name, directory, localized badge, field kind, required flag, and constraint metadata from live schema entries
+- no schema edit controls
+- mismatch banner and privileged `Sync Schema` action rendering when state says mismatch + `canSync`
+
+Reuse existing render patterns from:
+
+- `packages/studio/src/lib/remote-studio-app.test.ts`
+- `packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx`
+
+**Step 2: Run test to verify it fails**
+
+Run:
+
+```bash
+bun test packages/studio/src/lib/runtime-ui/app/admin/schema-page.test.tsx packages/studio/src/lib/remote-studio-app.test.ts
+```
+
+Expected:
+
+- FAIL because `/admin/schema` is still a static placeholder
+
+**Step 3: Write minimal implementation**
+
+Replace the current placeholder with a read-only browser component that consumes the shared schema state and renders:
+
+- top-level mismatch banner
+- optional sync action
+- grouped schema entries
+- field tables derived from `resolvedSchema.fields`
+
+Keep the UI truthful:
+
+- no builder copy
+- no drag-and-drop claims
+- no edit or mutation affordances
+
+**Step 4: Run test to verify it passes**
+
+Run:
+
+```bash
+bun test packages/studio/src/lib/runtime-ui/app/admin/schema-page.test.tsx packages/studio/src/lib/remote-studio-app.test.ts
+```
+
+Expected:
+
+- PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/studio/src/lib/runtime-ui/app/admin/schema-page.tsx packages/studio/src/lib/runtime-ui/app/admin/schema-page.test.tsx packages/studio/src/lib/remote-studio-app.tsx packages/studio/src/lib/remote-studio-app.test.ts
+git commit -m "feat(studio): add read-only schema browser"
+```
+
+### Task 4: Wire Guarded Read-Only Editor Recovery
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/runtime-ui/pages/content-document-page.tsx`
+- Modify: `packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx`
+- Modify: `packages/studio/src/lib/document-shell.ts`
+- Modify: `packages/studio/src/lib/document-route-api.ts`
+- Modify: `packages/studio/src/lib/document-route-api.test.ts`
+
+**Step 1: Write the failing document route tests**
+
+Cover:
+
+- mismatch state disables draft save and publish affordances
+- guarded banner renders the server-versus-local schema recovery state
+- privileged sync clears the mismatch path after successful reload
+- non-privileged users see read-only recovery text without the sync action
+- `SCHEMA_HASH_MISMATCH` and `SCHEMA_NOT_SYNCED` failures map into the guarded UI path rather than generic save errors
+
+**Step 2: Run test to verify it fails**
+
+Run:
+
+```bash
+bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx packages/studio/src/lib/document-route-api.test.ts
+```
+
+Expected:
+
+- FAIL because mismatch handling and recovery are not wired yet
+
+**Step 3: Write minimal implementation**
+
+Integrate the shared schema state into the existing document page state machine:
+
+- treat mismatch as guarded read-only
+- preserve readable content and version history
+- disable draft mutation and publish paths while guarded
+- surface sync recovery UI from the shared state
+
+Preserve the existing document route mount contract for save requests so the actual write path still sends `x-mdcms-schema-hash` when writes are allowed.
+
+**Step 4: Run test to verify it passes**
+
+Run:
+
+```bash
+bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx packages/studio/src/lib/document-route-api.test.ts
+```
+
+Expected:
+
+- PASS
+
+**Step 5: Commit**
+
+```bash

+git commit -m "feat(studio): guard document writes on schema mismatch"
+```
+
+### Task 5: Minimal Settings Integration And Documentation
+
+**Files:**
+
+- Modify: `packages/studio/src/lib/runtime-ui/app/admin/settings-page.tsx`
+- Modify: `packages/studio/README.md`
+
+**Step 1: Write the failing assertions**
+
+Add or extend tests so Settings does one of the following truthfully:
+
+- reuses the shared read-only schema browser content, or
+- links users to `/admin/schema` instead of maintaining a separate mock viewer
+
+Also add assertions for the updated README copy:
+
+- schema mismatch recovery is now live
+- `/admin/schema` is a live read-only browser
+
+**Step 2: Run test to verify it fails**
+
+Run:
+
+```bash
+bun test packages/studio/src/lib/remote-studio-app.test.ts packages/studio/src/lib/studio.test.ts
+```
+
+Expected:
+
+- FAIL until Settings and docs align with the live behavior
+
+**Step 3: Write minimal implementation**
+
+Keep this change narrow:
+
+- remove the duplicated mock schema viewer from Settings
+- replace it with shared schema access or a clear link to the real schema browser
+- update `packages/studio/README.md` at the point of use to describe the live schema browser and mismatch recovery workflow
+
+Do not clean up unrelated Settings tabs or post-MVP surfaces here.
+
+**Step 4: Run test to verify it passes**
+
+Run:
+
+```bash
+bun test packages/studio/src/lib/remote-studio-app.test.ts packages/studio/src/lib/studio.test.ts
+```
+
+Expected:
+
+- PASS
+
+**Step 5: Commit**
+
+```bash
+git add packages/studio/src/lib/runtime-ui/app/admin/settings-page.tsx packages/studio/README.md
+git commit -m "docs(studio): document schema guard and browser"
+```
+
+### Task 6: Full Verification
+
+**Files:**
+
+- Modify only if verification reveals a concrete failure
+
+**Step 1: Run focused Studio and shared tests**
+
+```bash
+bun test packages/studio/src packages/shared/src/lib/contracts
+```
+
+Expected:
+
+- PASS
+
+**Step 2: Run server schema/content tests that cover guarded-write compatibility**
+
+```bash
+bun test apps/server/src/lib/schema-api.test.ts apps/server/src/lib/content-api.integration.test.ts apps/server/src/lib/auth.test.ts
+```
+
+Expected:

+- PASS
+
+**Step 3: Run repository-required checks**
+
+```bash
+bun run format:check
+bun run check
+```
+
+Expected:
+
+- PASS
+
+**Step 4: Confirm local-only files stay unstaged**
+
+```bash
+git status --short
+```
+
+Expected:
+
+- `docs/plans/` may exist locally but is not staged for commit
+- local-only paths from `AGENTS.md` remain unstaged

+# Studio Review Preview Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add a private `apps/studio-review` Next.js app that renders MDCMS Studio against scenario-scoped mock API routes and a locally built Studio runtime so pull requests can review visual Studio changes without the full Compose stack.
+
+**Architecture:** Keep the real Studio package and production host app untouched. The review app owns its own `serverUrl` subtree (`/review-api/:scenario`) that serves a real bootstrap manifest plus runtime asset bytes using the existing `@mdcms/studio/build-runtime` helper, and serves deterministic mock API responses for capabilities, schema, and document endpoints through Next route handlers. The review admin route prepares a local Studio config with MDX component metadata and mounts the normal `<Studio />` component against those review-only endpoints.
+
+**Tech Stack:** Bun, Nx workspace apps, Next.js App Router, `@mdcms/studio`, `@mdcms/studio/build-runtime`, repo-local route handlers, node:test / Bun test, React server rendering tests.
+
+---

+
+import HomePage from "./page";

+# CMS-131 Content Overview Design
+
+## Scope
+
+Finish `CMS-131` by completing the `/admin/content` live overview so it can:
+
+- render truthful per-type `total`, `published`, and `drafts` counts for callers
+  with `content:read`
+- persist the Studio light/dark theme across reloads and remounts
+- keep the existing real schema-driven cards, locale badges, and localized demo
+  content intact
+
+## Design
+
+### Overview counts
+
+The current page derives counts by calling `GET /api/v1/content` with
+`limit=1` and reading `pagination.total`. That means the route still receives a
+real `data` array with document payloads even though the overview only needs
+counts. It also means `total` and `draft`-derived metrics currently depend on
+`draft=true`, which requires `content:read:draft`.
+
+To separate metadata visibility from draft document access:
+
+- add a dedicated `GET /api/v1/content/overview` endpoint in the content API
+- keep required scope at `content:read`
+- return metadata-only rows per requested type with no document bodies or list
+  payloads
+- define `drafts` as non-deleted documents whose current head has no published
+  version
+
+### Theme persistence
+
+The Studio `ThemeProvider` currently stores the theme only in React state and
+reapplies the `dark` class on mount. It should own browser-local persistence
+through `localStorage` and derive the effective theme using:
+
+1. persisted Studio preference
+2. explicit `defaultTheme`
+3. system preference when `enableSystem` is enabled
+4. `light`
+

+
+## Constraints
+
+- Keep CMS-131 scoped to `/admin/content`; do not broaden dashboard behavior.
+- Preserve the existing `GET /api/v1/content?draft=true` permission model.
+- Do not commit files under `docs/plans/`; they are local workflow artifacts in
+  this repo.

+# CMS-131 Content Overview Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Finish CMS-131 by adding a metadata-only content overview endpoint, wiring `/admin/content` to it, and persisting the Studio theme.
+
+**Architecture:** Extend the content API with a dedicated overview-count contract that exposes per-type metadata without document rows, then update the Studio overview loader to consume that contract while keeping list/detail permissions unchanged. Persist the Studio theme inside the existing runtime theme adapter with local browser storage and deterministic precedence.
+
+**Tech Stack:** Bun, Nx, TypeScript, React, Zod, custom server content API, GitHub CLI.
+
+---
+
+### Task 1: Spec delta
+
+**Files:**
+
+- Modify: `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
+- Modify: `docs/specs/SPEC-006-studio-runtime-and-ui.md`
+
+**Step 1: Write the spec delta**
+
+- Add `GET /api/v1/content/overview` as a metadata-only endpoint in `SPEC-003`
+- Update `/admin/content` count and theme persistence behavior in `SPEC-006`
+
+**Step 2: Verify wording against current code**
+
+Run: `rg -n "content/overview|theme persistence|/admin/content" docs/specs/SPEC-003-content-storage-versioning-and-migrations.md docs/specs/SPEC-006-studio-runtime-and-ui.md`
+
+Expected: the new contract text is present exactly once in each spec.

+
+### Findings
+
+| #   | Severity | File:Line                 | Issue                                                                                                                                                                          |
+| --- | -------- | ------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| 1   | HIGH     | `app-sidebar.tsx:78-82`   | **"Coming Soon" sidebar section** lists Scheduled, Audit Log, SEO Analysis. Roadmap leakage -- SPEC-006 does not define these routes. Sidebar advertises unbuilt capabilities. |
+| 2   | HIGH     | `page-header.tsx:248-255` | **"Profile" and "Preferences" user menu items** are non-functional. No onClick, no navigation target, no page exists. Dead affordances implying non-existent features.         |
+| 3   | LOW      | `app-sidebar.tsx:61`      | **API nav item uses `Search` icon** but the API page uses `Terminal`. Inconsistent.                                                                                            |
+| 4   | LOW      | `app-sidebar.tsx:60`      | **Workflows nav item uses `Sparkles` icon** but the Workflows page uses `GitBranch`. Inconsistent.                                                                             |
+
+### What's correct
+
+- Layout uses real APIs only (capabilities, session, environments) -- no mock-data.ts imports
+- User display from real session email with derived initials
+- Environment selector from real environment API
+- Role-gating of nav items (Schema, Users, Settings) via capabilities
+- Theme toggle, sign out, project badge all functional
+
+### Required changes
+
+- [ ] Remove the "Coming Soon" sidebar section entirely (lines 78-82, 164-225)
+- [ ] Remove non-functional "Profile" and "Preferences" from user menu (lines 248-255)
+- [ ] Align sidebar icons: API -> Terminal, Workflows -> GitBranch

+- Forbidden, error, loading states all deterministic
+- No live collaboration, activity feed, notification, or presence references
+- No mock-data.ts imports

+### Required changes
+
+- None. Dashboard is clean.

+- Schema-type cards keyed by live schema entries from real API
+- Per-type metrics (total, published, drafts) from real content overview API
+- Localization badges: "Localized" with locale list, "Single locale" -- matches spec
+- Deterministic states: loading, forbidden, error, empty, permission-constrained, ready
+- Permission-constrained view: cards visible, counts hidden, navigation disabled, clear banner
+- `canNavigate` gating properly disables type links when content.read is false
+- No mock-data.ts imports
+
+### Required changes
+
+- None. Content overview is clean.

+| --- | -------- | ----------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| 1   | HIGH     | `media-page.tsx:17-37`        | **Elaborate ghosted mock UI** -- 12 mock media items, 4 mock folders with counts, search bar, upload button, folder sidebar. Implies a nearly-built media library. Should be an intentional placeholder, not a blurred product preview.                                              |
+| 2   | HIGH     | `media-page.tsx:73-77`        | **Copy overclaims**: "Browse, search, tag, and organize all your media files" and "Reuse assets across documents with a powerful media management system." Claims capabilities that don't exist.                                                                                     |
+| 3   | HIGH     | `workflows-page.tsx:24-30`    | **Feature list overclaims**: "Multi-step approval workflows", "Role-based review assignments", "Scheduled content publishing", "Webhook triggers and notifications", "Audit trail and compliance tracking." Ticket explicitly says these must not be claimed.                        |
+| 4   | HIGH     | `api-page.tsx:24-30`          | **Feature list overclaims**: "Interactive GraphQL and REST explorer", "Auto-generated query builder", "Response previews with syntax highlighting", "Code generation for popular frameworks", "API key management and testing." Claims GraphQL, code generation, API key management. |
+| 5   | HIGH     | `coming-soon.tsx:36-46`       | **`<ComingSoon>` component renders "Planned features:" list** with bullets. Roadmap leakage by design. The component exists to advertise future features.                                                                                                                            |
+| 6   | MEDIUM   | `media-page.tsx` (whole file) | **Inconsistent treatment** -- Media page does NOT use `<ComingSoon>` component. Has its own custom layout while workflows and api use ComingSoon. Ticket requires consistent visual treatment.                                                                                       |
+| 7   | MEDIUM   | `coming-soon.tsx:48`          | **"Notify Me When Available" button** -- Disabled but implies a notification/subscription system that doesn't exist.                                                                                                                                                                 |
+| 8   | MEDIUM   | `media-page.tsx:143-153`      | **"Contribute on GitHub" link** points to bare `https://github.com`, not the actual repo. Dead/misleading link.                                                                                                                                                                      |

+
+### Required changes
+
+- [ ] Remove all mock media items, folders, ghosted UI from media page
+- [ ] Normalize media page to use `<ComingSoon>` component or equivalent consistent pattern
+- [ ] Rework `<ComingSoon>` component: remove "Planned features:" section and "Notify Me" button
+- [ ] Replace all overclaiming descriptions and feature lists with neutral MVP-safe copy
+- [ ] Remove dead GitHub link from media page
+
+---
+
+## Cross-cutting observations
+
+1. **mock-data.ts is NOT imported by any of the five audited surfaces.** Only consumed by out-of-scope pages (Users, Settings, Environments, Editor sidebar).
+
+2. **CMS-136, CMS-137, CMS-138 are clean.** Their dependency tasks (CMS-130, CMS-131, CMS-132) delivered real integrations that replaced mock behavior. No changes needed.
+
+3. **CMS-135 has 2 high-severity issues** in the shell: Coming Soon section and dead user menu items.
+
+4. **CMS-144 has the most findings** -- all three deferred pages overclaim. Media page is worst with its elaborate blurred mockup. The `<ComingSoon>` component itself needs rework.

+# CMS-67 Environment Field Badges Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Surface environment-specific field badges in the Studio document editor so editors can see which fields only exist in the active environment.
+
+**Architecture:** Derive serializable document-route metadata from the authored config, pass it through the Studio mount context, and render a badge section in the document sidebar from that metadata. Reuse the same metadata to keep the editor route aligned with the currently selected environment.
+
+**Tech Stack:** Bun, Nx, React, TypeScript, Zod runtime contract validation
+
+---
+
+### Task 1: Document Route Metadata Derivation

+**Step 2: Run test to verify it fails**
+
+Run: `bun test packages/studio/src/lib/document-route-schema.test.ts`
+
+**Step 3: Write minimal implementation**

+# MDCMS Integration Audit Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Audit MDCMS from an adopter's perspective by building greenfield and brownfield demo integrations in isolated temp directories, running the full local stack, and capturing concrete integration friction plus candidate abstractions.
+
+**Architecture:** Run one shared MDCMS backend/dev stack from the monorepo, then create multiple isolated temp apps under `/tmp` that consume local MDCMS packages. Assign independent temp apps to separate worker agents. Standardize each worker's findings into one comparable format so orchestration can synthesize a cross-app integration report.
+
+**Tech Stack:** Bun, Nx, Docker Compose, Next.js, Vite, React Router, local workspace package linking, MDCMS CLI/SDK/Studio
+
+---
+
+### Task 1: Shared Stack Baseline
+
+**Files:**
+
+- Read: `package.json`
+- Read: `docker-compose.dev.yml`
+- Read: `apps/studio-example/README.md`
+
+**Step 1: Start the shared stack**
+
+Run:
+
+```bash
+bun run compose:dev
+```
+
+Expected: the local stack starts successfully and keeps the server, Studio runtime, and example host app in watch mode.
+
+**Step 2: Verify the stack is reachable**
+
+Run:
+
+```bash
+curl -sf http://127.0.0.1:4000/healthz
+curl -sf http://127.0.0.1:4173
+```
+
+Expected: both endpoints return success.
+
+**Step 3: Record shared environment assumptions**
+
+Record:
+
+- server URL
+- seeded login credentials
+- seeded demo API key behavior
+- any startup failures or local prerequisites
+
+### Task 2: Create Audit Workspace and Reporting Skeleton
+
+**Files:**
+
+- Create: `/tmp/mdcms-audit.<id>/README.md`
+- Create: `/tmp/mdcms-audit.<id>/findings/summary.md`
+- Create: `/tmp/mdcms-audit.<id>/findings/template.md`
+- Create: `/tmp/mdcms-audit.<id>/progress.md`
+
+**Step 1: Create the temp root**
+
+Run:
+
+```bash
+mktemp -d /tmp/mdcms-audit.XXXXXX
+```
+
+Expected: a unique audit root is created.
+
+**Step 2: Create a reporting template**
+
+Include these required sections:
+
+- app/use case
+- exact step
+- expected effort
+- actual effort
+- friction
+- why this is unintuitive vs merely undocumented
+- repeated values / boilerplate
+- candidate abstraction
+- prototype attempted?
+- blocker severity
+
+**Step 3: Create a progress tracker**
+
+Track:
+
+- each app/use case
+- owner agent
+- current state
+- blockers
+- synthesis status
+
+### Task 3: Greenfield Next.js Host
+
+**Files:**
+
+- Create: `/tmp/mdcms-audit.<id>/greenfield-next/**`
+- Modify: app files inside that temp app only
+
+**Step 1: Scaffold the app**
+
+Create a fresh Next.js app in the temp root.
+
+**Step 2: Link MDCMS packages locally**
+
+Install or link:
+
+- `@mdcms/cli`
+- `@mdcms/sdk`
+- `@mdcms/studio`
+
+**Step 3: Execute these use cases deeply**
+
+Use cases:
+
+- SDK reads from seeded content
+- Studio catch-all route embed
+- local MDX component registration
+- target/environment handling
+- auth flow and CLI-assisted content workflow
+
+**Step 4: Capture friction and prototype helper wrappers where obvious**
+
+Prototype examples may include:
+
+- centralized MDCMS config readers
+- request-header helpers
+- Studio route wrapper components
+- SDK client factory helpers
+
+### Task 4: Greenfield Vite + React Router Host
+
+**Files:**
+
+- Create: `/tmp/mdcms-audit.<id>/greenfield-vite/**`
+- Modify: app files inside that temp app only
+
+**Step 1: Scaffold the app**
+
+Create a fresh Vite React app with React Router.
+
+**Step 2: Link MDCMS packages locally**
+
+Install or link:
+
+- `@mdcms/cli`
+- `@mdcms/sdk`
+- `@mdcms/studio`
+
+**Step 3: Execute these use cases deeply**
+
+Use cases:
+
+- SDK reads from seeded content
+- admin route integration
+- Studio embed attempt outside Next.js
+- environment/target handling
+- auth and CLI workflow from a non-Next host
+
+**Step 4: Capture friction and prototype helper wrappers where obvious**
+
+Pay special attention to anything that claims framework agnosticism but still assumes Next.js ergonomics.
+
+### Task 5: Brownfield Next.js Markdown App
+
+**Files:**
+
+- Create: `/tmp/mdcms-audit.<id>/brownfield-next/**`
+- Create: markdown content tree under that temp app
+- Modify: app files inside that temp app only
+
+**Step 1: Scaffold an app that already renders local markdown**
+
+Create:
+
+- content routes
+- filesystem content loader
+- a representative markdown tree
+
+**Step 2: Run `mdcms init` end to end**
+
+Use a unique `(project, environment)` pair for this app.
+
+**Step 3: Execute these use cases deeply**
+
+Use cases:
+
+- schema inference from existing markdown
+- locale detection/remapping
+- gitignore/untracking implications
+- preserving existing content routes while adopting MDCMS
+- adding Studio to an app with existing route/layout assumptions
+
+**Step 4: Migrate one content surface to MDCMS-backed reads**
+
+Compare:
+
+- old local markdown read path
+- direct API path
+- SDK path
+
+### Task 6: Brownfield Vite + React Router Markdown App
+
+**Files:**
+
+- Create: `/tmp/mdcms-audit.<id>/brownfield-vite/**`
+- Create: markdown content tree under that temp app
+- Modify: app files inside that temp app only
+
+**Step 1: Scaffold an app that already renders local markdown**
+
+Create:
+
+- routed pages
+- filesystem content loader
+- representative markdown and MDX-ish content
+
+**Step 2: Run `mdcms init` end to end**
+
+Use a unique `(project, environment)` pair for this app.
+
+**Step 3: Execute these use cases deeply**
+
+Use cases:
+
+- schema inference from existing markdown
+- preserving route compatibility
+- SDK migration path
+- admin route integration
+- Studio embed attempt in a non-Next brownfield host
+
+**Step 4: Compare migration burden**
+
+Measure:
+
+- duplicated config
+- repeated target/auth wiring
+- manual manifest/content mapping assumptions
+
+### Task 7: Additional Targeted Use Cases
+
+**Files:**
+
+- Create: `/tmp/mdcms-audit.<id>/cases/**`
+
+**Step 1: Add at least two focused mini-cases if needed**
+
+Examples:
+
+- single-locale markdown app
+- multi-locale markdown app with suffix/folder mismatch
+- MD vs MDX mixed tree
+- host app with custom base path or existing admin route namespace
+
+**Step 2: Use mini-cases only where a major finding needs sharper reproduction**
+
+Do not create extra apps unless they expose materially different friction.
+
+### Task 8: Standardized Worker Reporting
+
+**Files:**
+
+- Create: `/tmp/mdcms-audit.<id>/findings/*.md`
+
+**Step 1: Require every worker to produce one report per app**
+
+Each report must include:
+
+- what worked
+- what felt tedious
+- what felt unintuitive even with hypothetical docs
+- what values had to be repeated
+- what glue code should probably live in MDCMS library code
+- what helper the worker prototyped locally
+
+**Step 2: Require exact code references inside the temp app**
+
+The report must point to the concrete files that demonstrate the issue.
+
+### Task 9: Cross-Cutting Improvement Prototypes
+
+**Files:**
+
+- Modify: temp app helper files only
+
+**Step 1: Choose the highest-signal pain points**
+
+Examples:
+
+- repeated `project/environment/serverUrl` wiring
+- repeated auth header creation
+- server-component/client-component split for Studio config
+- manual MDX component metadata stripping/re-merging
+
+**Step 2: Prototype small wrappers**
+
+Examples:
+
+- `createMdcmsRuntimeConfig(...)`
+- `createScopedFetcher(...)`
+- `createStudioRoute(...)`
+- `createDemoSdkClient(...)` generalized beyond the demo app
+
+**Step 3: Keep prototypes local to temp apps**
+
+The audit should demonstrate better ergonomics without changing the monorepo implementation yet.
+
+### Task 10: Final Synthesis
+
+**Files:**
+
+- Create: `/tmp/mdcms-audit.<id>/findings/final-report.md`
+
+**Step 1: Build the use-case matrix**
+
+Columns:
+
+- use case
+- app
+- status
+- friction summary
+- blocker summary
+- candidate MDCMS fix
+
+**Step 2: Prioritize findings**
+
+Buckets:
+
+- abstraction gap
+- config duplication

+# Real Scenario MDCMS Audit Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Replace the current technical-slice MDCMS test-integrations repo with 10 real product scenarios arranged as 5 mirrored greenfield/brownfield pairs, then run the full integration flow for each and capture real adopter friction.
+
+**Architecture:** Use one shared local MDCMS stack, one target repo clone at `/tmp/mdcms-test-integrations`, and fresh temp workspaces per scenario pair. Each worker owns one mirrored domain pair so greenfield and brownfield remain comparable. The controller verifies repo shape, reviews friction findings for adopter relevance, and pushes only after the repo and reports reflect the real-scenario matrix.
+
+**Tech Stack:** Bun, Nx, Docker Compose, Next.js, Vite, React Router, MDCMS CLI, MDCMS SDK, MDCMS Studio, local workspace package linking
+
+---
+
+### Task 1: Reset The Scenario Matrix
+
+**Files:**
+
+- Modify: `/tmp/mdcms-test-integrations/README.md`
+- Delete/replace: current technical-slice app folders under `/tmp/mdcms-test-integrations/apps`
+
+**Step 1: Define the 5 mirrored real-world domains**
+
+Domains:
+
+- newsroom
+- product-docs
+- marketing-site
+- support-center
+- release-notes
+
+**Step 2: Map each domain to a framework and mirrored pair**
+
+Pairs:
+
+- `greenfield-newsroom-next`, `brownfield-newsroom-next`
+- `greenfield-product-docs-next`, `brownfield-product-docs-next`
+- `greenfield-marketing-site-next`, `brownfield-marketing-site-next`
+- `greenfield-support-center-vite`, `brownfield-support-center-vite`
+- `greenfield-release-notes-next`, `brownfield-release-notes-next`
+
+**Step 3: Remove non-scenario folder names**
+
+Delete/replace folders like:
+
+- `greenfield-next-sdk`
+- `greenfield-next-studio`
+- `greenfield-next-mdx`

+### User
+
+Can you tes connection to figma mcp
+
+### Assistant
+
+I’m checking the local Codex setup first so I can verify whether a Figma MCP server is configured and responding, then I’ll try a lightweight MCP call against it.
+
+### Assistant
+
+Using `using-superpowers` to follow the required skill-loading workflow before I inspect the MCP setup. Next I’m querying the configured MCP servers to see whether a Figma server is present and reachable.
+
+### Assistant
+
+The MCP registry isn’t exposing any resources or templates right now, which usually means either no server is configured for this session or the server failed to register. I’m checking the local MCP config next for any Figma entry and then I’ll try to confirm whether the process can actually start.
+
+### Assistant
+
+The local config looks like it used to have a `figma` MCP entry, but the current active config may not. I’m reading the active `~/.codex/config.toml` block directly and then I’ll probe the local Figma MCP URL if it still exists anywhere.
+
+### Assistant
+
+The endpoint itself is alive on `127.0.0.1:3845`; the `400` on a plain `GET` is expected for many MCP HTTP servers because they require a JSON-RPC request. I’m sending a minimal `initialize` call now to confirm whether the server speaks MCP properly.
+
+### Assistant
+
+The server completed `initialize` successfully and identified itself as `Figma Dev Mode MCP Server 1.0.0`. I’m doing one more protocol-level check by opening a session properly and asking for its tool list.
+
+### Assistant
+
+I tested it directly.
+
+- `http://127.0.0.1:3845/mcp` is reachable from this machine.
+- A proper MCP `initialize` request returned `200 OK` and identified itself as `Figma Dev Mode MCP Server` version `1.0.0`.
+- A follow-up `tools/list` call also succeeded and exposed tools including `get_design_context`, `get_variable_defs`, `get_screenshot`, `get_metadata`, `create_design_system_rules`, and `get_figjam`.
+
+One caveat: the active Codex config at [config.toml](~/.codex/config.toml) does not currently contain a `figma` MCP entry, so this session is not wired to use it through the built-in MCP registry yet. That matches the empty MCP resource/template listing I saw.
+
+If you want, I can add the Figma MCP entry back into [config.toml](~/.codex/config.toml) and tell you the exact restart step needed for Codex to pick it up.
+
+### User
+
+okay can you get the currently selected frame i have i want you to see the section "three decisions. everything else follows." and brainstorm ideas for copy for that section with be - both for the paragraphs/headers AND the embedded terminal views - we want something in the terminal that matches our actual experience and makes sense
+
+### Assistant
+
+Using `brainstorming` to shape the copy options before writing them. I’m pulling the currently selected Figma node through the MCP server now so I can inspect that section and make the terminal content match what’s actually on the screen.
+
+### Assistant
+
+I have the MCP server up; now I’m reading the currently selected node’s metadata and screenshot so the copy options track the real structure, not a guess. After that I’ll ask one narrow question about tone before I draft directions.
+
+### Assistant
+
+The MCP server is healthy, but the selected-node calls are being rejected by Figma with an access error. Please make sure your paid Figma seat includes Dev Mode access, you have permission to that file, and then send me the link to that exact frame or reselect it and tell me when it’s active.
+
+### Assistant
+
+The MCP connection works, but Figma refused access to the currently selected node, so I can’t see that section yet.
+
+Please make sure your paid Figma seat includes Dev Mode access, you have permission to that file, and then send me the link to that exact frame or reselect it and tell me when it’s active. Once I can read it, I’ll give you 2-3 copy directions for the header, paragraph, and realistic terminal content that matches the actual product experience.
+
+### User
+
+ok just see this then
+
+`<image>…screenshot of the “Three decisions. Everything else follows.” section with three numbered cards and repeated terminal snippets…</image>`
+
+### Assistant
+
+I can see the issue now: the three cards are carrying distinct architecture claims, but the terminal panels all repeat the same `init`/`validation` snippet, so only one of them even loosely matches the copy. The first choice I need from you is audience: is this section aimed primarily at CTO/engineering leads evaluating architecture, or hands-on developers who would actually use the CLI day to day?

+
+Read this convo to see what we mainly need to change here
+
+Karol Chudzik [9:00 AM]
+Mógłbyś mi powiedzieć jeszcze czego konkretnie potrzeba ode mnie w tym copy? W sensie po prostu powiedzieć czy to jest zgodne z prawdą to co tam piszemy i zrobić te snippety do terminala, czy wymyślić w ogóle od nowa? Bo imo to zależy konkretnie co chcemy podkreślić i jak to pozycjonować. Ale dla mnie "database is source of truth" nie ma sensu i nie widzę kogo miałoby to w ogóle interesować w jaki sposób przechowujemy ten content, a punktu "every interface is a full client" sam nie rozumiem o co w nim chodzi
+Karol Chudzik [9:15 AM]
+I do designu który task jest aktualny CMS-160 czy CMS-179 bo są dwa
+Saved for laterJakub Jabłoński [10:21 AM]
+replied to a thread:Wymyślić od nowa dla tej sekcji o której mówiłem bo tak ja mówisz jest z dupy
+
+Snippets z terminala dla sekcji wyżej z Content Codebase i Config
+
+### Assistant
+
+Using `brainstorming` to pin down what this section actually needs to communicate before drafting replacement copy. I’m extracting the concrete ask from the thread and then I’ll narrow the replacement direction with one question.
+
+### Assistant
+
+Main read from that thread: this is not a fact-check or light polish pass. It needs a full rewrite.
+
+What needs to change:
+
+- Jakub explicitly wants this section reinvented from scratch.
+- The current angle is wrong because it leads with internals instead of a meaningful promise.
+- `Database is the source of truth` was called out as not interesting or persuasive.
+- `Every interface is a full client` was called out as unclear even internally.
+- The repeated terminal panels are also in the wrong place. Jakub wants terminal snippets for the section above, around `Content Codebase` and `Config`, not for this `Three decisions` block.
+- The convo does not resolve the `CMS-160` vs `CMS-179` question.
+
+So the real task here is: replace this section with a clearer positioning idea, and move the terminal-proof moments to the section above where they actually support the message.
+
+If we replace this section entirely, what single promise do you want it to sell?
+
+### User
+
+No the terminals should be in this section as well, the terminals is a different thing we will come back to that in a bit, the layou should stay teh same
+
+Header
+Paragraph
+
+- termianl snippet
+
+`<image>…cropped screenshot of one card showing header, paragraph, and terminal snippet layout…</image>`
+
+### Assistant
+
+Layout stays: each block remains `header + paragraph + terminal snippet`. The change is the message, not the structure, and the terminals still need to support each block instead of repeating the same generic `init` output.
+
+### Assistant
+
+One question to pin the direction down: should these three blocks explain internal architectural decisions, or should they translate those decisions into buyer-facing outcomes?
+
+My recommendation is buyer-facing outcomes, because the current problem is exactly that the copy sounds like implementation notes instead of a reason to care.
+

+
+My recommendation is buyer-facing outcomes, because the current problem is exactly that the copy sounds like implementation notes instead of a reason to care.
+
+### User
+
+yes outcomes
+
+### Assistant
+
+I have the direction now: keep the layout, but rewrite each card around outcomes instead of internals. I’m checking the existing docs and site copy so the new claims stay defensible and the terminal snippets map to real product behaviors.
+
+### Assistant
+
+The docs are useful here because they expose a more convincing message than the current copy: the real product truths are about explicit schema control, file-based workflows, and shared routing/contracts across CLI, Studio, and SDK. I’m doing one last pass on the existing marketing/source files to see whether the brand voice prefers `cms`, `mdcms`, or `arch.cms` in terminal examples before I draft the options.
+
+### Assistant
+
+Three viable directions for this section, all outcome-led and grounded in the actual product:
+
+1. **Operate content like software**. Recommended.
+
+- Why it works: this is the clearest bridge between the product truth and the buyer outcome. MDCMS really does use code-defined schema, explicit sync, and shared server contracts.
+- What the three cards would emphasize:
+  - schema changes are explicit and reviewable
+  - content workflows stay predictable across local files and the backend
+  - CLI, Studio, and SDK all act on the same project/environment scope
+- Terminal feel:
+  - `mdcms schema sync`
+  - `mdcms pull`
+  - `mdcms status` or `mdcms push --dry-run`
+- Trade-off: slightly more technical, but it sounds like a serious tool instead of generic CMS marketing.
+
+2. **No hidden state**
+
+- Why it works: this turns the section into a contrast story. No secret schema editor, no silent drift, no special admin path.
+- What the cards would emphasize:
+  - structure lives in config you can inspect
+  - writes fail loudly when schema is out of sync
+  - every surface follows the same rules
+- Terminal feel:
+  - schema hash mismatch guidance
+  - pull plan output
+  - scoped status output
+- Trade-off: sharper and more memorable, but more negative in tone.
+
+3. **Move faster without losing control**
+
+- Why it works: broader and more buyer-friendly. It translates architecture into team outcomes instead of implementation details.
+- What the cards would emphasize:
+  - faster setup and safer iteration
+  - fewer surprises between local and remote state
+  - consistent behavior across tools and teammates
+- Terminal feel:
+  - concise setup/sync confirmation
+  - dry-run plan
+  - target scope confirmation
+- Trade-off: easiest to read, but also the most likely to drift into generic SaaS copy.
+
+My recommendation is **Operate content like software**. It gives you a strong headline system, matches the repo truth, and gives the terminal snippets something concrete to prove.
+
+One important detail: if these terminals are meant to feel real, I would switch them to `mdcms` or `cms`, because that is what the repo/docs actually define. `arch.cms` reads like marketing fiction unless that alias really exists.
+
+If this direction looks right, I’ll turn it into actual replacement copy for all three cards: header, paragraph, and matching terminal snippet.
+
+### User
+
+"Operate content like software" I don't feel like this makes ton of sense like what does this even mean? is this just advertising our cli interface or what
+
+### Assistant
+
+You’re right. That phrase is too vague, and it drifts toward “look, we have a CLI,” which is not the point of the section. The terminal should be proof of the operating model, not the thing being sold.
+
+### Assistant
+
+You’re right. That phrase is too vague, and it drifts toward “look, we have a CLI,” which is not the point of the section.
+
+What this section should probably sell instead is one of these clearer outcomes:
+
+1. **Content changes stay controlled**
+
+- Meaning: schema changes are explicit, reviewable, and don’t happen through a hidden admin UI.
+- Good if you want to position against messy CMS sprawl.
+
+2. **Teams don’t lose each other’s work**
+
+- Meaning: editors, developers, and automation can all work in parallel without creating drift or mystery state.
+- Good if you want the section to feel more collaborative and less infra-heavy.
+
+3. **Every tool follows the same rules**. Recommended.
+
+- Meaning: Studio, CLI, and SDK are different interfaces to the same system, so behavior is consistent instead of fragmented.
+- This is clearer than “every interface is a full client,” but says the same thing in plain English.
+
+So no, I would not frame this as “we have a CLI.” I’d frame it as:
+
+- predictable changes
+- less drift/conflict
+- consistent behavior across surfaces
+
+The terminal then becomes evidence for each claim:
+
+- explicit sync
+- explicit pull/push/status
+- explicit scoped behavior
+
+Which of those three outcomes do you want the section to emphasize most: control, collaboration, or consistency?
+
+### User
+
+also i feel like the configuration as code point should stay because it is a unique selling point i think
+
+### Assistant
+
+Yes. I would keep that point.
+
+The issue is not `configuration as code` itself. The issue is that `Configuration lives in code.` reads like an implementation detail instead of a reason to care.
+
+That card should probably keep the mechanism, but sell the outcome:
+
+- `Change structure in code. Review it like code.`
+- `Your content model lives in the repo.`
+- `No hidden schema editor.`
+
+And the paragraph can translate why that matters:
+
+- content types and fields are defined in `mdcms.config.ts`
+- changes go through the same review flow as the rest of the product
+- Studio reflects the config, but does not become a second place where structure can drift
+
+So I’d treat this as:
+
+- one card can stay explicitly about config-as-code, because it is distinctive
+- the other two cards should be outcome-first, not architecture-notes-first
+
+A cleaner shape for the three cards could be:
+
+1. Config as code
+2. Content changes stay in sync
+3. Every surface follows the same rules
+
+For the config card alone, my recommendation is this direction:
+
+Header:
+`Your content model lives in code.`
+
+Paragraph:
+`Types, fields, and environment rules are defined in \`mdcms.config.ts\`, not rebuilt in an admin panel. The Studio reads that config, so structure changes stay reviewable and ship through the same workflow as the rest of your app.`
+
+One question: do you want that card to say `code` explicitly in the header, or keep the header more benefit-led and move `mdcms.config.ts` into the paragraph only?
+
+### User
+
+i like this one Your content model lives in the repo.
+
+### Assistant
+
+That header works. I’m validating the matching terminal proof against the actual CLI now so the snippet feels like something the product would really say, not placeholder console noise.
+
+### Assistant
+
+I found the real CLI surfaces we can lean on. `schema sync`, `status`, `pull`, and `push --dry-run` all print concrete, product-specific output, so we can make the terminal panels feel legitimate instead of fabricated.
+
+### Assistant
+
+I’m locking this card first before touching the other two. The strongest version is to keep the repo angle in the header, then make the paragraph explain why that matters operationally, with `schema sync` as the proof.
+
+### Assistant
+
+For that card, I’d tighten it to this:
+
+Header:
+`Your content model lives in the repo.`
+
+Paragraph:
+`Types, fields, and environment rules live in \`mdcms.config.ts\`, so structure changes go through pull requests instead of a hidden schema editor. The Studio reads the same config, which keeps your model versioned, reviewable, and aligned with the app it serves.`
+
+Terminal:
+
+```text
+$ mdcms schema sync
+Schema synced (hash: 8f3c1b7a2d41)
+Affected types: BlogPost, Author, Page
+```
+
+This feels right because the header is outcome-first, but the terminal proves a real mechanism instead of hand-wavy “developer experience” copy. The snippet also matches the actual CLI shape, so it won’t read fake.
+
+If this card looks right, I’ll draft the second one next.

+# Grouped Content List Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add grouped localized content rows to the content list API and Studio `/admin/content/:type` so localized logical documents render once per translation group.
+
+**Architecture:** Extend the existing `GET /api/v1/content` contract with `groupBy=translationGroup` for localized types, aggregate rows server-side after filtering and before pagination, then update Studio's content list client and type list UI to consume grouped entries instead of raw locale documents. Keep non-localized behavior unchanged.
+
+**Tech Stack:** Bun, Nx, TypeScript, Bun test, Studio React runtime, server content API/database store.

+# Skills
+
+This directory holds the canonical skill set for this repo. Every supported agent (Claude Code, Codex, Cursor) discovers it via a symlink:
+
+- `.claude/skills` → `../.ai/skills`
+- `.agents/skills` → `../.ai/skills`
+- `.cursor/skills` → `../.ai/skills`
+
+Skill format is the [Anthropic Agent Skill (`SKILL.md`)](https://platform.claude.com/docs/en/agents-and-tools/agent-skills/overview) standard.
+
+## Vendored skills
+
+The skills below are vendored from [obra/superpowers](https://github.com/obra/superpowers) v5.0.7, MIT-licensed (see `LICENSE.superpowers`). Copyright (c) 2025 Jesse Vincent. To bump the version:
+
+```bash
+SP_VER=5.x.x
+cp -r ~/.claude/plugins/cache/claude-plugins-official/superpowers/$SP_VER/skills/* .ai/skills/
+cp ~/.claude/plugins/cache/claude-plugins-official/superpowers/$SP_VER/LICENSE .ai/skills/LICENSE.superpowers
+# Update the version above and verify by running a smoke test in a fresh session
+```
+
+Vendored skills:
+
+- `brainstorming/`
+- `dispatching-parallel-agents/`
+- `executing-plans/`
+- `finishing-a-development-branch/`

+
+## Why a vendored copy
+
+The global `superpowers` plugin is disabled at the project level via `.claude/settings.json` so the vendored copy is the only set of skills active when working in this repo. This makes the agent harness reproducible: clone the repo, you get the same skill set, no "did you install the plugin globally" failure mode.

+name: brainstorming
+description: "You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation."
+---
+
+# Brainstorming Ideas Into Designs
+
+Help turn ideas into fully formed designs and specs through natural collaborative dialogue.
+
+Start by understanding the current project context, then ask questions one at a time to refine the idea. Once you understand what you're building, present the design and get user approval.
+
+<HARD-GATE>
+Do NOT invoke any implementation skill, write any code, scaffold any project, or take any implementation action until you have presented a design and the user has approved it. This applies to EVERY project regardless of perceived simplicity.
+</HARD-GATE>
+
+## Anti-Pattern: "This Is Too Simple To Need A Design"
+
+Every project goes through this process. A todo list, a single-function utility, a config change — all of them. "Simple" projects are where unexamined assumptions cause the most wasted work. The design can be short (a few sentences for truly simple projects), but you MUST present it and get approval.
+
+## Checklist
+
+You MUST create a task for each of these items and complete them in order:
+
+1. **Explore project context** — check files, docs, recent commits
+2. **Offer visual companion** (if topic will involve visual questions) — this is its own message, not combined with a clarifying question. See the Visual Companion section below.
+3. **Ask clarifying questions** — one at a time, understand purpose/constraints/success criteria
+4. **Propose 2-3 approaches** — with trade-offs and your recommendation
+5. **Present design** — in sections scaled to their complexity, get user approval after each section
+6. **Write design doc** — save to `.ai/research/YYYY-MM-DD-<topic>-design.md` and commit
+7. **Spec self-review** — quick inline check for placeholders, contradictions, ambiguity, scope (see below)
+8. **User reviews written spec** — ask user to review the spec file before proceeding
+9. **Transition to implementation** — invoke writing-plans skill to create implementation plan
+
+## Process Flow
+
+```dot
+digraph brainstorming {
+    "Explore project context" [shape=box];
+    "Visual questions ahead?" [shape=diamond];
+    "Offer Visual Companion\n(own message, no other content)" [shape=box];
+    "Ask clarifying questions" [shape=box];
+    "Propose 2-3 approaches" [shape=box];
+    "Present design sections" [shape=box];
+    "User approves design?" [shape=diamond];
+    "Write design doc" [shape=box];
+    "Spec self-review\n(fix inline)" [shape=box];

+    "Invoke writing-plans skill" [shape=doublecircle];
+
+    "Explore project context" -> "Visual questions ahead?";
+    "Visual questions ahead?" -> "Offer Visual Companion\n(own message, no other content)" [label="yes"];
+    "Visual questions ahead?" -> "Ask clarifying questions" [label="no"];
+    "Offer Visual Companion\n(own message, no other content)" -> "Ask clarifying questions";
+    "Ask clarifying questions" -> "Propose 2-3 approaches";
+    "Propose 2-3 approaches" -> "Present design sections";
+    "Present design sections" -> "User approves design?";
+    "User approves design?" -> "Present design sections" [label="no, revise"];
+    "User approves design?" -> "Write design doc" [label="yes"];
+    "Write design doc" -> "Spec self-review\n(fix inline)";
+    "Spec self-review\n(fix inline)" -> "User reviews spec?";
+    "User reviews spec?" -> "Write design doc" [label="changes requested"];
+    "User reviews spec?" -> "Invoke writing-plans skill" [label="approved"];
+}
+```
+
+**The terminal state is invoking writing-plans.** Do NOT invoke frontend-design, mcp-builder, or any other implementation skill. The ONLY skill you invoke after brainstorming is writing-plans.
+
+## The Process
+
+**Understanding the idea:**
+
+- Check out the current project state first (files, docs, recent commits)
+- Before asking detailed questions, assess scope: if the request describes multiple independent subsystems (e.g., "build a platform with chat, file storage, billing, and analytics"), flag this immediately. Don't spend questions refining details of a project that needs to be decomposed first.
+- If the project is too large for a single spec, help the user decompose into sub-projects: what are the independent pieces, how do they relate, what order should they be built? Then brainstorm the first sub-project through the normal design flow. Each sub-project gets its own spec → plan → implementation cycle.
+- For appropriately-scoped projects, ask questions one at a time to refine the idea
+- Prefer multiple choice questions when possible, but open-ended is fine too
+- Only one question per message - if a topic needs more exploration, break it into multiple questions
+- Focus on understanding: purpose, constraints, success criteria
+
+**Exploring approaches:**
+
+- Propose 2-3 different approaches with trade-offs
+- Present options conversationally with your recommendation and reasoning
+- Lead with your recommended option and explain why
+
+**Presenting the design:**
+
+- Once you believe you understand what you're building, present the design
+- Scale each section to its complexity: a few sentences if straightforward, up to 200-300 words if nuanced
+- Ask after each section whether it looks right so far
+- Cover: architecture, components, data flow, error handling, testing
+- Be ready to go back and clarify if something doesn't make sense
+
+**Design for isolation and clarity:**
+
+- Break the system into smaller units that each have one clear purpose, communicate through well-defined interfaces, and can be understood and tested independently
+- For each unit, you should be able to answer: what does it do, how do you use it, and what does it depend on?
+- Can someone understand what a unit does without reading its internals? Can you change the internals without breaking consumers? If not, the boundaries need work.
+- Smaller, well-bounded units are also easier for you to work with - you reason better about code you can hold in context at once, and your edits are more reliable when files are focused. When a file grows large, that's often a signal that it's doing too much.
+
+**Working in existing codebases:**
+
+- Explore the current structure before proposing changes. Follow existing patterns.
+- Where existing code has problems that affect the work (e.g., a file that's grown too large, unclear boundaries, tangled responsibilities), include targeted improvements as part of the design - the way a good developer improves code they're working in.
+- Don't propose unrelated refactoring. Stay focused on what serves the current goal.
+
+## After the Design
+
+**Documentation:**
+
+- Write the validated design (spec) to `.ai/research/YYYY-MM-DD-<topic>-design.md`
+  - (User preferences for spec location override this default)
+- Use elements-of-style:writing-clearly-and-concisely skill if available
+- Commit the design document to git
+
+**Spec Self-Review:**
+After writing the spec document, look at it with fresh eyes:
+
+1. **Placeholder scan:** Any "TBD", "TODO", incomplete sections, or vague requirements? Fix them.
+2. **Internal consistency:** Do any sections contradict each other? Does the architecture match the feature descriptions?
+3. **Scope check:** Is this focused enough for a single implementation plan, or does it need decomposition?
+4. **Ambiguity check:** Could any requirement be interpreted two different ways? If so, pick one and make it explicit.
+
+Fix any issues inline. No need to re-review — just fix and move on.
+
+**User Review Gate:**
+After the spec review loop passes, ask the user to review the written spec before proceeding:
+
+> "Spec written and committed to `<path>`. Please review it and let me know if you want to make any changes before we start writing out the implementation plan."
+
+Wait for the user's response. If they request changes, make them and re-run the spec review loop. Only proceed once the user approves.
+
+**Implementation:**
+
+- Invoke the writing-plans skill to create a detailed implementation plan
+- Do NOT invoke any other skill. writing-plans is the next step.
+
+## Key Principles
+
+- **One question at a time** - Don't overwhelm with multiple questions
+- **Multiple choice preferred** - Easier to answer than open-ended when possible
+- **YAGNI ruthlessly** - Remove unnecessary features from all designs
+- **Explore alternatives** - Always propose 2-3 approaches before settling
+- **Incremental validation** - Present design, get approval before moving on
+- **Be flexible** - Go back and clarify when something doesn't make sense
+
+## Visual Companion
+
+A browser-based companion for showing mockups, diagrams, and visual options during brainstorming. Available as a tool — not a mode. Accepting the companion means it's available for questions that benefit from visual treatment; it does NOT mean every question goes through the browser.
+
+**Offering the companion:** When you anticipate that upcoming questions will involve visual content (mockups, layouts, diagrams), offer it once for consent:
+> "Some of what we're working on might be easier to explain if I can show it to you in a web browser. I can put together mockups, diagrams, comparisons, and other visuals as we go. This feature is still new and can be token-intensive. Want to try it? (Requires opening a local URL)"
+
+**This offer MUST be its own message.** Do not combine it with clarifying questions, context summaries, or any other content. The message should contain ONLY the offer above and nothing else. Wait for the user's response before continuing. If they decline, proceed with text-only brainstorming.
+
+**Per-question decision:** Even after the user accepts, decide FOR EACH QUESTION whether to use the browser or the terminal. The test: **would the user understand this better by seeing it than reading it?**
+
+- **Use the browser** for content that IS visual — mockups, wireframes, layout comparisons, architecture diagrams, side-by-side visual designs
+- **Use the terminal** for content that is text — requirements questions, conceptual choices, tradeoff lists, A/B/C/D text options, scope decisions
+
+A question about a UI topic is not automatically a visual question. "What does personality mean in this context?" is a conceptual question — use the terminal. "Which wizard layout works better?" is a visual question — use the browser.
+
+If they agree to the companion, read the detailed guide before proceeding:

+# Spec Document Reviewer Prompt Template
+
+Use this template when dispatching a spec document reviewer subagent.
+
+**Purpose:** Verify the spec is complete, consistent, and ready for implementation planning.
+
+**Dispatch after:** Spec document is written to .ai/research/
+
+```
+Task tool (general-purpose):
+  description: "Review spec document"
+  prompt: |
+    You are a spec document reviewer. Verify this spec is complete and ready for planning.
+
+    **Spec to review:** [SPEC_FILE_PATH]
+
+    ## What to Check
+
+    | Category | What to Look For |
+    |----------|------------------|
+    | Completeness | TODOs, placeholders, "TBD", incomplete sections |
+    | Consistency | Internal contradictions, conflicting requirements |
+    | Clarity | Requirements ambiguous enough to cause someone to build the wrong thing |
+    | Scope | Focused enough for a single plan — not covering multiple independent subsystems |
+    | YAGNI | Unrequested features, over-engineering |
+
+    ## Calibration
+
+    **Only flag issues that would cause real problems during implementation planning.**
+    A missing section, a contradiction, or a requirement so ambiguous it could be
+    interpreted two different ways — those are issues. Minor wording improvements,
+    stylistic preferences, and "sections less detailed than others" are not.
+
+    Approve unless there are serious gaps that would lead to a flawed plan.
+
+    ## Output Format
+
+    ## Spec Review
+
+    **Status:** Approved | Issues Found
+
+    **Issues (if any):**
+    - [Section X]: [specific issue] - [why it matters for planning]
+
+    **Recommendations (advisory, do not block approval):**
+    - [suggestions for improvement]
+```
+

+# Visual Companion Guide
+
+Browser-based visual brainstorming companion for showing mockups, diagrams, and options.
+
+## When to Use
+
+Decide per-question, not per-session. The test: **would the user understand this better by seeing it than reading it?**
+
+**Use the browser** when the content itself is visual:
+
+- **UI mockups** — wireframes, layouts, navigation structures, component designs
+- **Architecture diagrams** — system components, data flow, relationship maps
+- **Side-by-side visual comparisons** — comparing two layouts, two color schemes, two design directions
+- **Design polish** — when the question is about look and feel, spacing, visual hierarchy
+- **Spatial relationships** — state machines, flowcharts, entity relationships rendered as diagrams
+
+**Use the terminal** when the content is text or tabular:
+
+- **Requirements and scope questions** — "what does X mean?", "which features are in scope?"
+- **Conceptual A/B/C choices** — picking between approaches described in words
+- **Tradeoff lists** — pros/cons, comparison tables
+- **Technical decisions** — API design, data modeling, architectural approach selection
+- **Clarifying questions** — anything where the answer is words, not a visual preference
+
+A question *about* a UI topic is not automatically a visual question. "What kind of wizard do you want?" is conceptual — use the terminal. "Which of these wizard layouts feels right?" is visual — use the browser.
+
+## How It Works
+
+The server watches a directory for HTML files and serves the newest one to the browser. You write HTML content to `screen_dir`, the user sees it in their browser and can click to select options. Selections are recorded to `state_dir/events` that you read on your next turn.
+
+**Content fragments vs full documents:** If your HTML file starts with `<!DOCTYPE` or `<html`, the server serves it as-is (just injects the helper script). Otherwise, the server automatically wraps your content in the frame template — adding the header, CSS theme, selection indicator, and all interactive infrastructure. **Write content fragments by default.** Only write full documents when you need complete control over the page.
+
+## Starting a Session
+
+```bash
+# Start server with persistence (mockups saved to project)
+scripts/start-server.sh --project-dir /path/to/project
+
+# Returns: {"type":"server-started","port":52341,"url":"http://localhost:52341",
+#           "screen_dir":"/path/to/project/.superpowers/brainstorm/12345-1706000000/content",
+#           "state_dir":"/path/to/project/.superpowers/brainstorm/12345-1706000000/state"}
+```
+
+Save `screen_dir` and `state_dir` from the response. Tell user to open the URL.
+
+**Finding connection info:** The server writes its startup JSON to `$STATE_DIR/server-info`. If you launched the server in the background and didn't capture stdout, read that file to get the URL and port. When using `--project-dir`, check `<project>/.superpowers/brainstorm/` for the session directory.
+
+**Note:** Pass the project root as `--project-dir` so mockups persist in `.superpowers/brainstorm/` and survive server restarts. Without it, files go to `/tmp` and get cleaned up. Remind the user to add `.superpowers/` to `.gitignore` if it's not already there.
+
+**Launching the server by platform:**
+
+**Claude Code (macOS / Linux):**
+```bash
+# Default mode works — the script backgrounds the server itself
+scripts/start-server.sh --project-dir /path/to/project
+```
+
+**Claude Code (Windows):**
+```bash
+# Windows auto-detects and uses foreground mode, which blocks the tool call.
+# Use run_in_background: true on the Bash tool call so the server survives
+# across conversation turns.
+scripts/start-server.sh --project-dir /path/to/project
+```
+When calling this via the Bash tool, set `run_in_background: true`. Then read `$STATE_DIR/server-info` on the next turn to get the URL and port.
+
+**Codex:**
+```bash
+# Codex reaps background processes. The script auto-detects CODEX_CI and
+# switches to foreground mode. Run it normally — no extra flags needed.
+scripts/start-server.sh --project-dir /path/to/project
+```
+
+**Gemini CLI:**
+```bash
+# Use --foreground and set is_background: true on your shell tool call
+# so the process survives across turns
+scripts/start-server.sh --project-dir /path/to/project --foreground
+```
+
+**Other environments:** The server must keep running in the background across conversation turns. If your environment reaps detached processes, use `--foreground` and launch the command with your platform's background execution mechanism.
+
+If the URL is unreachable from your browser (common in remote/containerized setups), bind a non-loopback host:
+
+```bash
+scripts/start-server.sh \
+  --project-dir /path/to/project \
+  --host 0.0.0.0 \
+  --url-host localhost
+```
+
+Use `--url-host` to control what hostname is printed in the returned URL JSON.
+
+## The Loop
+
+1. **Check server is alive**, then **write HTML** to a new file in `screen_dir`:
+   - Before each write, check that `$STATE_DIR/server-info` exists. If it doesn't (or `$STATE_DIR/server-stopped` exists), the server has shut down — restart it with `start-server.sh` before continuing. The server auto-exits after 30 minutes of inactivity.
+   - Use semantic filenames: `platform.html`, `visual-style.html`, `layout.html`
+   - **Never reuse filenames** — each screen gets a fresh file
+   - Use Write tool — **never use cat/heredoc** (dumps noise into terminal)
+   - Server automatically serves the newest file
+
+2. **Tell user what to expect and end your turn:**
+   - Remind them of the URL (every step, not just first)
+   - Give a brief text summary of what's on screen (e.g., "Showing 3 layout options for the homepage")
+   - Ask them to respond in the terminal: "Take a look and let me know what you think. Click to select an option if you'd like."
+
+3. **On your next turn** — after the user responds in the terminal:
+   - Read `$STATE_DIR/events` if it exists — this contains the user's browser interactions (clicks, selections) as JSON lines
+   - Merge with the user's terminal text to get the full picture
+   - The terminal message is the primary feedback; `state_dir/events` provides structured interaction data
+
+4. **Iterate or advance** — if feedback changes current screen, write a new file (e.g., `layout-v2.html`). Only move to the next question when the current step is validated.
+
+5. **Unload when returning to terminal** — when the next step doesn't need the browser (e.g., a clarifying question, a tradeoff discussion), push a waiting screen to clear the stale content:
+
+   ```html
+   <!-- filename: waiting.html (or waiting-2.html, etc.) -->
+   <div style="display:flex;align-items:center;justify-content:center;min-height:60vh">
+     <p class="subtitle">Continuing in terminal...</p>
+   </div>
+   ```
+
+   This prevents the user from staring at a resolved choice while the conversation has moved on. When the next visual question comes up, push a new content file as usual.
+
+6. Repeat until done.
+
+## Writing Content Fragments
+
+Write just the content that goes inside the page. The server wraps it in the frame template automatically (header, theme CSS, selection indicator, and all interactive infrastructure).
+
+**Minimal example:**
+
+```html
+<h2>Which layout works better?</h2>
+<p class="subtitle">Consider readability and visual hierarchy</p>
+
+<div class="options">
+  <div class="option" data-choice="a" onclick="toggleSelect(this)">
+    <div class="letter">A</div>
+    <div class="content">
+      <h3>Single Column</h3>
+      <p>Clean, focused reading experience</p>
+    </div>
+  </div>
+  <div class="option" data-choice="b" onclick="toggleSelect(this)">
+    <div class="letter">B</div>
+    <div class="content">
+      <h3>Two Column</h3>
+      <p>Sidebar navigation with main content</p>
+    </div>
+  </div>
+</div>
+```
+
+That's it. No `<html>`, no CSS, no `<script>` tags needed. The server provides all of that.
+
+## CSS Classes Available
+
+The frame template provides these CSS classes for your content:
+
+### Options (A/B/C choices)
+
+```html
+<div class="options">
+  <div class="option" data-choice="a" onclick="toggleSelect(this)">
+    <div class="letter">A</div>
+    <div class="content">
+      <h3>Title</h3>
+      <p>Description</p>
+    </div>
+  </div>
+</div>
+```
+
+**Multi-select:** Add `data-multiselect` to the container to let users select multiple options. Each click toggles the item. The indicator bar shows the count.
+
+```html
+<div class="options" data-multiselect>
+  <!-- same option markup — users can select/deselect multiple -->
+</div>
+```
+
+### Cards (visual designs)
+
+```html
+<div class="cards">
+  <div class="card" data-choice="design1" onclick="toggleSelect(this)">
+    <div class="card-image"><!-- mockup content --></div>
+    <div class="card-body">
+      <h3>Name</h3>
+      <p>Description</p>
+    </div>
+  </div>
+</div>
+```
+
+### Mockup container
+
+```html
+<div class="mockup">
+  <div class="mockup-header">Preview: Dashboard Layout</div>
+  <div class="mockup-body"><!-- your mockup HTML --></div>
+</div>
+```
+
+### Split view (side-by-side)
+
+```html
+<div class="split">
+  <div class="mockup"><!-- left --></div>
+  <div class="mockup"><!-- right --></div>
+</div>
+```
+
+### Pros/Cons
+
+```html
+<div class="pros-cons">
+  <div class="pros"><h4>Pros</h4><ul><li>Benefit</li></ul></div>
+  <div class="cons"><h4>Cons</h4><ul><li>Drawback</li></ul></div>
+</div>
+```
+
+### Mock elements (wireframe building blocks)
+
+```html
+<div class="mock-nav">Logo | Home | About | Contact</div>
+<div style="display: flex;">
+  <div class="mock-sidebar">Navigation</div>
+  <div class="mock-content">Main content area</div>
+</div>
+<button class="mock-button">Action Button</button>
+<input class="mock-input" placeholder="Input field">
+<div class="placeholder">Placeholder area</div>
+```
+
+### Typography and sections
+
+- `h2` — page title
+- `h3` — section heading
+- `.subtitle` — secondary text below title
+- `.section` — content block with bottom margin
+- `.label` — small uppercase label text
+
+## Browser Events Format
+
+When the user clicks options in the browser, their interactions are recorded to `$STATE_DIR/events` (one JSON object per line). The file is cleared automatically when you push a new screen.
+
+```jsonl
+{"type":"click","choice":"a","text":"Option A - Simple Layout","timestamp":1706000101}
+{"type":"click","choice":"c","text":"Option C - Complex Grid","timestamp":1706000108}
+{"type":"click","choice":"b","text":"Option B - Hybrid","timestamp":1706000115}
+```
+
+The full event stream shows the user's exploration path — they may click multiple options before settling. The last `choice` event is typically the final selection, but the pattern of clicks can reveal hesitation or preferences worth asking about.
+
+If `$STATE_DIR/events` doesn't exist, the user didn't interact with the browser — use only their terminal text.
+
+## Design Tips
+
+- **Scale fidelity to the question** — wireframes for layout, polish for polish questions
+- **Explain the question on each page** — "Which layout feels more professional?" not just "Pick one"
+- **Iterate before advancing** — if feedback changes current screen, write a new version
+- **2-4 options max** per screen
+- **Use real content when it matters** — for a photography portfolio, use actual images (Unsplash). Placeholder content obscures design issues.
+- **Keep mockups simple** — focus on layout and structure, not pixel-perfect design
+
+## File Naming
+
+- Use semantic names: `platform.html`, `visual-style.html`, `layout.html`
+- Never reuse filenames — each screen must be a new file
+- For iterations: append version suffix like `layout-v2.html`, `layout-v3.html`
+- Server serves newest file by modification time
+
+## Cleaning Up
+
+```bash
+scripts/stop-server.sh $SESSION_DIR
+```
+
+If the session used `--project-dir`, mockup files persist in `.superpowers/brainstorm/` for later reference. Only `/tmp` sessions get deleted on stop.
+

+name: dispatching-parallel-agents
+description: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies
+---
+
+# Dispatching Parallel Agents
+
+## Overview
+
+You delegate tasks to specialized agents with isolated context. By precisely crafting their instructions and context, you ensure they stay focused and succeed at their task. They should never inherit your session's context or history — you construct exactly what they need. This also preserves your own context for coordination work.
+
+When you have multiple unrelated failures (different test files, different subsystems, different bugs), investigating them sequentially wastes time. Each investigation is independent and can happen in parallel.
+
+**Core principle:** Dispatch one agent per independent problem domain. Let them work concurrently.
+
+## When to Use
+
+```dot
+digraph when_to_use {
+    "Multiple failures?" [shape=diamond];
+    "Are they independent?" [shape=diamond];
+    "Single agent investigates all" [shape=box];
+    "One agent per problem domain" [shape=box];
+    "Can they work in parallel?" [shape=diamond];
+    "Sequential agents" [shape=box];
+    "Parallel dispatch" [shape=box];
+
+    "Multiple failures?" -> "Are they independent?" [label="yes"];
+    "Are they independent?" -> "Single agent investigates all" [label="no - related"];
+    "Are they independent?" -> "Can they work in parallel?" [label="yes"];
+    "Can they work in parallel?" -> "Parallel dispatch" [label="yes"];
+    "Can they work in parallel?" -> "Sequential agents" [label="no - shared state"];
+}
+```
+
+**Use when:**
+- 3+ test files failing with different root causes
+- Multiple subsystems broken independently
+- Each problem can be understood without context from others
+- No shared state between investigations
+
+**Don't use when:**
+- Failures are related (fix one might fix others)
+- Need to understand full system state
+- Agents would interfere with each other
+
+## The Pattern
+
+### 1. Identify Independent Domains
+
+Group failures by what's broken:
+- File A tests: Tool approval flow
+- File B tests: Batch completion behavior
+- File C tests: Abort functionality
+
+Each domain is independent - fixing tool approval doesn't affect abort tests.
+
+### 2. Create Focused Agent Tasks
+
+Each agent gets:
+- **Specific scope:** One test file or subsystem
+- **Clear goal:** Make these tests pass
+- **Constraints:** Don't change other code
+- **Expected output:** Summary of what you found and fixed
+
+### 3. Dispatch in Parallel
+
+```typescript
+// In Claude Code / AI environment
+Task("Fix agent-tool-abort.test.ts failures")
+Task("Fix batch-completion-behavior.test.ts failures")
+Task("Fix tool-approval-race-conditions.test.ts failures")
+// All three run concurrently
+```
+
+### 4. Review and Integrate
+
+When agents return:
+- Read each summary
+- Verify fixes don't conflict
+- Run full test suite
+- Integrate all changes
+
+## Agent Prompt Structure
+
+Good agent prompts are:
+1. **Focused** - One clear problem domain
+2. **Self-contained** - All context needed to understand the problem
+3. **Specific about output** - What should the agent return?
+
+```markdown
+Fix the 3 failing tests in src/agents/agent-tool-abort.test.ts:
+
+1. "should abort tool with partial output capture" - expects 'interrupted at' in message
+2. "should handle mixed completed and aborted tools" - fast tool aborted instead of completed
+3. "should properly track pendingToolCount" - expects 3 results but gets 0
+
+These are timing/race condition issues. Your task:
+
+1. Read the test file and understand what each test verifies
+2. Identify root cause - timing issues or actual bugs?
+3. Fix by:
+   - Replacing arbitrary timeouts with event-based waiting
+   - Fixing bugs in abort implementation if found
+   - Adjusting test expectations if testing changed behavior
+
+Do NOT just increase timeouts - find the real issue.
+
+Return: Summary of what you found and what you fixed.
+```
+
+## Common Mistakes
+
+**❌ Too broad:** "Fix all the tests" - agent gets lost
+**✅ Specific:** "Fix agent-tool-abort.test.ts" - focused scope
+
+**❌ No context:** "Fix the race condition" - agent doesn't know where
+**✅ Context:** Paste the error messages and test names
+
+**❌ No constraints:** Agent might refactor everything
+**✅ Constraints:** "Do NOT change production code" or "Fix tests only"
+
+**❌ Vague output:** "Fix it" - you don't know what changed
+**✅ Specific:** "Return summary of root cause and changes"
+
+## When NOT to Use
+
+**Related failures:** Fixing one might fix others - investigate together first
+**Need full context:** Understanding requires seeing entire system
+**Exploratory debugging:** You don't know what's broken yet
+**Shared state:** Agents would interfere (editing same files, using same resources)
+
+## Real Example from Session
+
+**Scenario:** 6 test failures across 3 files after major refactoring
+
+**Failures:**
+- agent-tool-abort.test.ts: 3 failures (timing issues)
+- batch-completion-behavior.test.ts: 2 failures (tools not executing)
+- tool-approval-race-conditions.test.ts: 1 failure (execution count = 0)
+
+**Decision:** Independent domains - abort logic separate from batch completion separate from race conditions
+
+**Dispatch:**
+```
+Agent 1 → Fix agent-tool-abort.test.ts
+Agent 2 → Fix batch-completion-behavior.test.ts
+Agent 3 → Fix tool-approval-race-conditions.test.ts
+```
+
+**Results:**
+- Agent 1: Replaced timeouts with event-based waiting
+- Agent 2: Fixed event structure bug (threadId in wrong place)
+- Agent 3: Added wait for async tool execution to complete
+
+**Integration:** All fixes independent, no conflicts, full suite green
+
+**Time saved:** 3 problems solved in parallel vs sequentially
+
+## Key Benefits
+
+1. **Parallelization** - Multiple investigations happen simultaneously
+2. **Focus** - Each agent has narrow scope, less context to track
+3. **Independence** - Agents don't interfere with each other
+4. **Speed** - 3 problems solved in time of 1
+
+## Verification
+
+After agents return:
+1. **Review each summary** - Understand what changed
+2. **Check for conflicts** - Did agents edit same code?
+3. **Run full suite** - Verify all fixes work together
+4. **Spot check** - Agents can make systematic errors
+
+## Real-World Impact
+
+From debugging session (2025-10-03):
+- 6 failures across 3 files
+- 3 agents dispatched in parallel
+- All investigations completed concurrently
+- All fixes integrated successfully
+- Zero conflicts between agent changes

If subagents are available, use superpowers:subagent-driven-development instead of this skill.
+
+## The Process
+
+### Step 1: Load and Review Plan
+1. Read plan file
+2. Review critically - identify any questions or concerns about the plan
+3. If concerns: Raise them with your human partner before starting
+4. If no concerns: Create TodoWrite and proceed
+
+### Step 2: Execute Tasks
+
+For each task:
+1. Mark as in_progress
+2. Follow each step exactly (plan has bite-sized steps)
+3. Run verifications as specified
+4. Mark as completed
+
+### Step 3: Complete Development
+
+After all tasks complete and verified:
+- Announce: "I'm using the finishing-a-development-branch skill to complete this work."
+- **REQUIRED SUB-SKILL:** Use superpowers:finishing-a-development-branch
+- Follow that skill to verify tests, present options, execute choice
+
+## When to Stop and Ask for Help
+
+**STOP executing immediately when:**
+- Hit a blocker (missing dependency, test fails, instruction unclear)
+- Plan has critical gaps preventing starting
+- You don't understand an instruction
+- Verification fails repeatedly
+
+**Ask for clarification rather than guessing.**
+
+## When to Revisit Earlier Steps
+
+**Return to Review (Step 1) when:**
+- Partner updates the plan based on your feedback
+- Fundamental approach needs rethinking
+
+**Don't force through blockers** - stop and ask.
+
+## Remember
+- Review plan critically first
+- Follow plan steps exactly
+- Don't skip verifications
+- Reference skills when plan says to
+- Stop when blocked, don't guess
+- Never start implementation on main/master branch without explicit user consent
+
+## Integration
+
+**Required workflow skills:**
+- **superpowers:using-git-worktrees** - REQUIRED: Set up isolated workspace before starting
+- **superpowers:writing-plans** - Creates the plan this skill executes
+- **superpowers:finishing-a-development-branch** - Complete development after all tasks

+name: finishing-a-development-branch
+description: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup
+---
+
+# Finishing a Development Branch
+
+## Overview
+
+Guide completion of development work by presenting clear options and handling chosen workflow.
+
+**Core principle:** Verify tests → Present options → Execute choice → Clean up.
+
+**Announce at start:** "I'm using the finishing-a-development-branch skill to complete this work."
+
+## The Process
+
+### Step 1: Verify Tests
+
+**Before presenting options, verify tests pass:**
+
+```bash
+# Run project's test suite
+npm test / cargo test / pytest / go test ./...
+```
+
+**If tests fail:**
+```
+Tests failing (<N> failures). Must fix before completing:
+
+[Show failures]
+
+Cannot proceed with merge/PR until tests pass.
+```
+
+Stop. Don't proceed to Step 2.
+
+**If tests pass:** Continue to Step 2.
+
+### Step 2: Determine Base Branch
+
+```bash
+# Try common base branches
+git merge-base HEAD main 2>/dev/null || git merge-base HEAD master 2>/dev/null
+```
+
+Or ask: "This branch split from main - is that correct?"
+
+### Step 3: Present Options
+
+Present exactly these 4 options:
+
+```
+Implementation complete. What would you like to do?
+
+1. Merge back to <base-branch> locally
+2. Push and create a Pull Request
+3. Keep the branch as-is (I'll handle it later)
+4. Discard this work
+
+Which option?
+```
+
+**Don't add explanation** - keep options concise.
+
+### Step 4: Execute Choice
+
+#### Option 1: Merge Locally
+
+```bash
+# Switch to base branch
+git checkout <base-branch>
+
+# Pull latest
+git pull
+
+# Merge feature branch
+git merge <feature-branch>
+
+# Verify tests on merged result
+<test command>
+
+# If tests pass
+git branch -d <feature-branch>
+```
+
+Then: Cleanup worktree (Step 5)
+
+#### Option 2: Push and Create PR
+
+```bash
+# Push branch
+git push -u origin <feature-branch>
+
+# Create PR
+gh pr create --title "<title>" --body "$(cat <<'EOF'
+## Summary
+<2-3 bullets of what changed>
+
+## Test Plan
+- [ ] <verification steps>
+EOF
+)"
+```
+
+Then: Cleanup worktree (Step 5)
+
+#### Option 3: Keep As-Is
+
+Report: "Keeping branch <name>. Worktree preserved at <path>."
+
+**Don't cleanup worktree.**
+
+#### Option 4: Discard
+
+**Confirm first:**
+```
+This will permanently delete:
+- Branch <name>
+- All commits: <commit-list>
+- Worktree at <path>
+
+Type 'discard' to confirm.
+```
+
+Wait for exact confirmation.
+
+If confirmed:
+```bash
+git checkout <base-branch>
+git branch -D <feature-branch>
+```
+
+Then: Cleanup worktree (Step 5)
+
+### Step 5: Cleanup Worktree
+
+**For Options 1, 2, 4:**
+
+Check if in worktree:
+```bash
+git worktree list | grep $(git branch --show-current)
+```
+
+If yes:
+```bash
+git worktree remove <worktree-path>
+```
+
+**For Option 3:** Keep worktree.
+
+## Quick Reference
+
+| Option | Merge | Push | Keep Worktree | Cleanup Branch |
+|--------|-------|------|---------------|----------------|
+| 1. Merge locally | ✓ | - | - | ✓ |
+| 2. Create PR | - | ✓ | ✓ | - |
+| 3. Keep as-is | - | - | ✓ | - |
+| 4. Discard | - | - | - | ✓ (force) |
+
+## Common Mistakes
+
+**Skipping test verification**
+- **Problem:** Merge broken code, create failing PR
+- **Fix:** Always verify tests before offering options
+
+**Open-ended questions**
+- **Problem:** "What should I do next?" → ambiguous
+- **Fix:** Present exactly 4 structured options
+
+**Automatic worktree cleanup**
+- **Problem:** Remove worktree when might need it (Option 2, 3)
+- **Fix:** Only cleanup for Options 1 and 4
+
+**No confirmation for discard**
+- **Problem:** Accidentally delete work
+- **Fix:** Require typed "discard" confirmation
+
+## Red Flags
+
+**Never:**
+- Proceed with failing tests
+- Merge without verifying tests on result
+- Delete work without confirmation
+- Force-push without explicit request
+
+**Always:**
+- Verify tests before offering options
+- Present exactly 4 options
+- Get typed confirmation for Option 4
+- Clean up worktree for Options 1 & 4 only
+
+## Integration
+
+**Called by:**
+- **subagent-driven-development** (Step 7) - After all tasks complete
+- **executing-plans** (Step 5) - After all batches complete
+
+**Pairs with:**
+- **using-git-worktrees** - Cleans up worktree created by that skill

+name: receiving-code-review
+description: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation
+---
+
+# Code Review Reception
+
+## Overview
+
+Code review requires technical evaluation, not emotional performance.
+
+**Core principle:** Verify before implementing. Ask before assuming. Technical correctness over social comfort.
+
+## The Response Pattern
+
+```
+WHEN receiving code review feedback:
+
+1. READ: Complete feedback without reacting
+2. UNDERSTAND: Restate requirement in own words (or ask)
+3. VERIFY: Check against codebase reality
+4. EVALUATE: Technically sound for THIS codebase?
+5. RESPOND: Technical acknowledgment or reasoned pushback
+6. IMPLEMENT: One item at a time, test each
+```
+
+## Forbidden Responses
+
+**NEVER:**
+- "You're absolutely right!" (explicit CLAUDE.md violation)
+- "Great point!" / "Excellent feedback!" (performative)
+- "Let me implement that now" (before verification)
+
+**INSTEAD:**
+- Restate the technical requirement
+- Ask clarifying questions
+- Push back with technical reasoning if wrong
+- Just start working (actions > words)
+
+## Handling Unclear Feedback
+
+```
+IF any item is unclear:
+  STOP - do not implement anything yet
+  ASK for clarification on unclear items
+
+WHY: Items may be related. Partial understanding = wrong implementation.
+```
+
+**Example:**
+```
+your human partner: "Fix 1-6"
+You understand 1,2,3,6. Unclear on 4,5.
+
+❌ WRONG: Implement 1,2,3,6 now, ask about 4,5 later
+✅ RIGHT: "I understand items 1,2,3,6. Need clarification on 4 and 5 before proceeding."
+```
+
+## Source-Specific Handling
+
+### From your human partner
+- **Trusted** - implement after understanding
+- **Still ask** if scope unclear
+- **No performative agreement**
+- **Skip to action** or technical acknowledgment
+
+### From External Reviewers
+```
+BEFORE implementing:
+  1. Check: Technically correct for THIS codebase?
+  2. Check: Breaks existing functionality?
+  3. Check: Reason for current implementation?
+  4. Check: Works on all platforms/versions?
+  5. Check: Does reviewer understand full context?
+
+IF suggestion seems wrong:
+  Push back with technical reasoning
+
+IF can't easily verify:
+  Say so: "I can't verify this without [X]. Should I [investigate/ask/proceed]?"
+
+IF conflicts with your human partner's prior decisions:
+  Stop and discuss with your human partner first
+```
+
+**your human partner's rule:** "External feedback - be skeptical, but check carefully"
+
+## YAGNI Check for "Professional" Features
+
+```
+IF reviewer suggests "implementing properly":
+  grep codebase for actual usage
+
+  IF unused: "This endpoint isn't called. Remove it (YAGNI)?"
+  IF used: Then implement properly
+```
+
+**your human partner's rule:** "You and reviewer both report to me. If we don't need this feature, don't add it."
+
+## Implementation Order
+
+```
+FOR multi-item feedback:
+  1. Clarify anything unclear FIRST
+  2. Then implement in this order:
+     - Blocking issues (breaks, security)
+     - Simple fixes (typos, imports)
+     - Complex fixes (refactoring, logic)
+  3. Test each fix individually
+  4. Verify no regressions
+```
+
+## When To Push Back
+
+Push back when:
+- Suggestion breaks existing functionality
+- Reviewer lacks full context
+- Violates YAGNI (unused feature)
+- Technically incorrect for this stack
+- Legacy/compatibility reasons exist
+- Conflicts with your human partner's architectural decisions
+
+**How to push back:**
+- Use technical reasoning, not defensiveness
+- Ask specific questions
+- Reference working tests/code
+- Involve your human partner if architectural
+
+**Signal if uncomfortable pushing back out loud:** "Strange things are afoot at the Circle K"
+
+## Acknowledging Correct Feedback
+
+When feedback IS correct:
+```
+✅ "Fixed. [Brief description of what changed]"
+✅ "Good catch - [specific issue]. Fixed in [location]."
+✅ [Just fix it and show in the code]
+
+❌ "You're absolutely right!"
+❌ "Great point!"
+❌ "Thanks for catching that!"
+❌ "Thanks for [anything]"
+❌ ANY gratitude expression
+```
+
+**Why no thanks:** Actions speak. Just fix it. The code itself shows you heard the feedback.
+
+**If you catch yourself about to write "Thanks":** DELETE IT. State the fix instead.
+
+## Gracefully Correcting Your Pushback
+
+If you pushed back and were wrong:
+```
+✅ "You were right - I checked [X] and it does [Y]. Implementing now."
+✅ "Verified this and you're correct. My initial understanding was wrong because [reason]. Fixing."
+
+❌ Long apology
+❌ Defending why you pushed back
+❌ Over-explaining
+```
+
+State the correction factually and move on.
+
+## Common Mistakes
+
+| Mistake | Fix |
+|---------|-----|
+| Performative agreement | State requirement or just act |
+| Blind implementation | Verify against codebase first |
+| Batch without testing | One at a time, test each |
+| Assuming reviewer is right | Check if breaks things |
+| Avoiding pushback | Technical correctness > comfort |
+| Partial implementation | Clarify all items first |
+| Can't verify, proceed anyway | State limitation, ask for direction |
+
+## Real Examples
+
+**Performative Agreement (Bad):**
+```
+Reviewer: "Remove legacy code"
+❌ "You're absolutely right! Let me remove that..."
+```
+
+**Technical Verification (Good):**
+```
+Reviewer: "Remove legacy code"
+✅ "Checking... build target is 10.15+, this API needs 13+. Need legacy for backward compat. Current impl has wrong bundle ID - fix it or drop pre-13 support?"
+```
+
+**YAGNI (Good):**
+```
+Reviewer: "Implement proper metrics tracking with database, date filters, CSV export"
+✅ "Grepped codebase - nothing calls this endpoint. Remove it (YAGNI)? Or is there usage I'm missing?"
+```
+
+**Unclear Item (Good):**
+```
+your human partner: "Fix items 1-6"
+You understand 1,2,3,6. Unclear on 4,5.
+✅ "Understand 1,2,3,6. Need clarification on 4 and 5 before implementing."
+```
+
+## GitHub Thread Replies
+
+When replying to inline review comments on GitHub, reply in the comment thread (`gh api repos/{owner}/{repo}/pulls/{pr}/comments/{id}/replies`), not as a top-level PR comment.
+
+## The Bottom Line
+
+**External feedback = suggestions to evaluate, not orders to follow.**
+
+Verify. Question. Then implement.
+
+No performative agreement. Technical rigor always.

+---
+
+# Requesting Code Review
+
+Dispatch superpowers:code-reviewer subagent to catch issues before they cascade. The reviewer gets precisely crafted context for evaluation — never your session's history. This keeps the reviewer focused on the work product, not your thought process, and preserves your own context for continued work.
+
+**Core principle:** Review early, review often.
+
+## When to Request Review
+
+**Mandatory:**
+- After each task in subagent-driven development
+- After completing major feature
+- Before merge to main
+
+**Optional but valuable:**
+- When stuck (fresh perspective)
+- Before refactoring (baseline check)
+- After fixing complex bug
+
+## How to Request
+
+**1. Get git SHAs:**
+```bash
+BASE_SHA=$(git rev-parse HEAD~1)  # or origin/main
+HEAD_SHA=$(git rev-parse HEAD)
+```
+
+**2. Dispatch code-reviewer subagent:**
+
+Use Task tool with superpowers:code-reviewer type, fill template at `code-reviewer.md`
+
+**Placeholders:**
+- `{WHAT_WAS_IMPLEMENTED}` - What you just built
+- `{PLAN_OR_REQUIREMENTS}` - What it should do
+- `{BASE_SHA}` - Starting commit
+- `{HEAD_SHA}` - Ending commit
+- `{DESCRIPTION}` - Brief summary
+
+**3. Act on feedback:**
+- Fix Critical issues immediately
+- Fix Important issues before proceeding
+- Note Minor issues for later
+- Push back if reviewer is wrong (with reasoning)
+
+## Example
+
+```
+[Just completed Task 2: Add verification function]
+
+You: Let me request code review before proceeding.
+
+BASE_SHA=$(git log --oneline | grep "Task 1" | head -1 | awk '{print $1}')
+HEAD_SHA=$(git rev-parse HEAD)
+
+[Dispatch superpowers:code-reviewer subagent]
+  WHAT_WAS_IMPLEMENTED: Verification and repair functions for conversation index
+  PLAN_OR_REQUIREMENTS: Task 2 from .ai/plans/deployment-plan.md
+  BASE_SHA: a7981ec
+  HEAD_SHA: 3df7661
+  DESCRIPTION: Added verifyIndex() and repairIndex() with 4 issue types
+
+[Subagent returns]:
+  Strengths: Clean architecture, real tests
+  Issues:
+    Important: Missing progress indicators
+    Minor: Magic number (100) for reporting interval
+  Assessment: Ready to proceed
+
+You: [Fix progress indicators]
+[Continue to Task 3]
+```
+
+## Integration with Workflows
+
+**Subagent-Driven Development:**
+- Review after EACH task
+- Catch issues before they compound
+- Fix before moving to next task
+
+**Executing Plans:**
+- Review after each batch (3 tasks)
+- Get feedback, apply, continue
+
+**Ad-Hoc Development:**
+- Review before merge
+- Review when stuck
+
+## Red Flags
+
+**Never:**
+- Skip review because "it's simple"
+- Ignore Critical issues
+- Proceed with unfixed Important issues
+- Argue with valid technical feedback
+
+**If reviewer wrong:**
+- Push back with technical reasoning
+- Show code/tests that prove it works
+- Request clarification
+

+
+### Strengths
+[What's well done? Be specific.]
+
+### Issues
+
+#### Critical (Must Fix)
+[Bugs, security issues, data loss risks, broken functionality]
+
+#### Important (Should Fix)
+[Architecture problems, missing features, poor error handling, test gaps]
+
+#### Minor (Nice to Have)
+[Code style, optimization opportunities, documentation improvements]
+
+**For each issue:**
+- File:line reference

+- Why it matters
+- How to fix (if not obvious)
+
+### Recommendations
+[Improvements for code quality, architecture, or process]
+
+### Assessment
+
+**Ready to merge?** [Yes/No/With fixes]
+
+**Reasoning:** [Technical assessment in 1-2 sentences]
+
+## Critical Rules
+
+**DO:**
+- Categorize by actual severity (not everything is Critical)
+- Be specific (file:line, not vague)
+- Explain WHY issues matter
+- Acknowledge strengths
+- Give clear verdict
+
+**DON'T:**
+- Say "looks good" without checking
+- Mark nitpicks as Critical
+- Give feedback on code you didn't review
+- Be vague ("improve error handling")
+- Avoid giving a clear verdict
+
+## Example Output
+
+```
+### Strengths
+- Clean database schema with proper migrations (db.ts:15-42)
+- Comprehensive test coverage (18 tests, all edge cases)
+- Good error handling with fallbacks (summarizer.ts:85-92)
+
+### Issues
+
+#### Important
+1. **Missing help text in CLI wrapper**
+   - File: index-conversations:1-31
+   - Issue: No --help flag, users won't discover --concurrency
+   - Fix: Add --help case with usage examples
+
+2. **Date validation missing**
+   - File: search.ts:25-27
+   - Issue: Invalid dates silently return no results
+   - Fix: Validate ISO format, throw error with example
+
+#### Minor
+1. **Progress indicators**
+   - File: indexer.ts:130
+   - Issue: No "X of Y" counter for long operations
+   - Impact: Users don't know how long to wait
+
+### Recommendations
+- Add progress reporting for user experience
+- Consider config file for excluded projects (portability)
+
+### Assessment
+
+**Ready to merge: With fixes**
+
+**Reasoning:** Core implementation is solid with good architecture and tests. Important issues (help text, date validation) are easily fixed and don't affect core functionality.

+description: Use when executing implementation plans with independent tasks in the current session
+---
+
+# Subagent-Driven Development
+
+Execute plan by dispatching fresh subagent per task, with two-stage review after each: spec compliance review first, then code quality review.
+
+**Why subagents:** You delegate tasks to specialized agents with isolated context. By precisely crafting their instructions and context, you ensure they stay focused and succeed at their task. They should never inherit your session's context or history — you construct exactly what they need. This also preserves your own context for coordination work.
+
+**Core principle:** Fresh subagent per task + two-stage review (spec then quality) = high quality, fast iteration
+
+## When to Use
+
+```dot
+digraph when_to_use {
+    "Have implementation plan?" [shape=diamond];
+    "Tasks mostly independent?" [shape=diamond];
+    "Stay in this session?" [shape=diamond];
+    "subagent-driven-development" [shape=box];
+    "executing-plans" [shape=box];
+    "Manual execution or brainstorm first" [shape=box];
+
+    "Have implementation plan?" -> "Tasks mostly independent?" [label="yes"];
+    "Have implementation plan?" -> "Manual execution or brainstorm first" [label="no"];
+    "Tasks mostly independent?" -> "Stay in this session?" [label="yes"];
+    "Tasks mostly independent?" -> "Manual execution or brainstorm first" [label="no - tightly coupled"];
+    "Stay in this session?" -> "subagent-driven-development" [label="yes"];
+    "Stay in this session?" -> "executing-plans" [label="no - parallel session"];
+}
+```
+
+**vs. Executing Plans (parallel session):**
+- Same session (no context switch)
+- Fresh subagent per task (no context pollution)
+- Two-stage review after each task: spec compliance first, then code quality
+- Faster iteration (no human-in-loop between tasks)
+
+## The Process
+
+```dot
+digraph process {
+    rankdir=TB;
+
+    subgraph cluster_per_task {
+        label="Per Task";

+}
+```
+
+## Model Selection
+
+Use the least powerful model that can handle each role to conserve cost and increase speed.
+
+**Mechanical implementation tasks** (isolated functions, clear specs, 1-2 files): use a fast, cheap model. Most implementation tasks are mechanical when the plan is well-specified.
+
+**Integration and judgment tasks** (multi-file coordination, pattern matching, debugging): use a standard model.
+
+**Architecture, design, and review tasks**: use the most capable available model.
+
+**Task complexity signals:**
+- Touches 1-2 files with a complete spec → cheap model
+- Touches multiple files with integration concerns → standard model
+- Requires design judgment or broad codebase understanding → most capable model
+
+## Handling Implementer Status
+
+Implementer subagents report one of four statuses. Handle each appropriately:
+
+**DONE:** Proceed to spec compliance review.
+
+**DONE_WITH_CONCERNS:** The implementer completed the work but flagged doubts. Read the concerns before proceeding. If the concerns are about correctness or scope, address them before review. If they're observations (e.g., "this file is getting large"), note them and proceed to review.
+
+**NEEDS_CONTEXT:** The implementer needs information that wasn't provided. Provide the missing context and re-dispatch.
+
+**BLOCKED:** The implementer cannot complete the task. Assess the blocker:
+1. If it's a context problem, provide more context and re-dispatch with the same model
+2. If the task requires more reasoning, re-dispatch with a more capable model
+3. If the task is too large, break it into smaller pieces
+4. If the plan itself is wrong, escalate to the human
+
+**Never** ignore an escalation or force the same model to retry without changes. If the implementer said it's stuck, something needs to change.
+
+## Prompt Templates
+
+- `./implementer-prompt.md` - Dispatch implementer subagent
+- `./spec-reviewer-prompt.md` - Dispatch spec compliance reviewer subagent
+- `./code-quality-reviewer-prompt.md` - Dispatch code quality reviewer subagent
+
+## Example Workflow
+
+```
+You: I'm using Subagent-Driven Development to execute this plan.
+
+[Read plan file once: .ai/plans/feature-plan.md]
+[Extract all 5 tasks with full text and context]
+[Create TodoWrite with all tasks]
+
+Task 1: Hook installation script
+
+[Get Task 1 text and context (already extracted)]
+[Dispatch implementation subagent with full task text + context]
+
+Implementer: "Before I begin - should the hook be installed at user or system level?"
+
+You: "User level (~/.config/superpowers/hooks/)"
+
+Implementer: "Got it. Implementing now..."
+[Later] Implementer:
+  - Implemented install-hook command
+  - Added tests, 5/5 passing
+  - Self-review: Found I missed --force flag, added it
+  - Committed
+
+[Dispatch spec compliance reviewer]
+Spec reviewer: ✅ Spec compliant - all requirements met, nothing extra
+
+[Get git SHAs, dispatch code quality reviewer]
+Code reviewer: Strengths: Good test coverage, clean. Issues: None. Approved.
+
+[Mark Task 1 complete]
+
+Task 2: Recovery modes
+
+[Get Task 2 text and context (already extracted)]
+[Dispatch implementation subagent with full task text + context]
+
+Implementer: [No questions, proceeds]
+Implementer:
+  - Added verify/repair modes
+  - 8/8 tests passing
+  - Self-review: All good
+  - Committed
+
+[Dispatch spec compliance reviewer]
+Spec reviewer: ❌ Issues:
+  - Missing: Progress reporting (spec says "report every 100 items")
+  - Extra: Added --json flag (not requested)
+
+[Implementer fixes issues]
+Implementer: Removed --json flag, added progress reporting
+
+[Spec reviewer reviews again]
+Spec reviewer: ✅ Spec compliant now
+
+[Dispatch code quality reviewer]
+Code reviewer: Strengths: Solid. Issues (Important): Magic number (100)
+
+[Implementer fixes]
+Implementer: Extracted PROGRESS_INTERVAL constant
+
+[Code reviewer reviews again]
+Code reviewer: ✅ Approved
+
+[Mark Task 2 complete]
+
+...
+
+[After all tasks]
+[Dispatch final code-reviewer]
+Final reviewer: All requirements met, ready to merge
+
+Done!
+```
+
+## Advantages
+
+**vs. Manual execution:**
+- Subagents follow TDD naturally
+- Fresh context per task (no confusion)
+- Parallel-safe (subagents don't interfere)
+- Subagent can ask questions (before AND during work)
+
+**vs. Executing Plans:**
+- Same session (no handoff)
+- Continuous progress (no waiting)
+- Review checkpoints automatic
+
+**Efficiency gains:**
+- No file reading overhead (controller provides full text)
+- Controller curates exactly what context is needed
+- Subagent gets complete information upfront
+- Questions surfaced before work begins (not after)
+
+**Quality gates:**
+- Self-review catches issues before handoff
+- Two-stage review: spec compliance, then code quality
+- Review loops ensure fixes actually work
+- Spec compliance prevents over/under-building
+- Code quality ensures implementation is well-built
+
+**Cost:**
+- More subagent invocations (implementer + 2 reviewers per task)
+- Controller does more prep work (extracting all tasks upfront)
+- Review loops add iterations
+- But catches issues early (cheaper than debugging later)
+
+## Red Flags
+
+**Never:**
+- Start implementation on main/master branch without explicit user consent
+- Skip reviews (spec compliance OR code quality)
+- Proceed with unfixed issues
+- Dispatch multiple implementation subagents in parallel (conflicts)
+- Make subagent read plan file (provide full text instead)
+- Skip scene-setting context (subagent needs to understand where task fits)
+- Ignore subagent questions (answer before letting them proceed)
+- Accept "close enough" on spec compliance (spec reviewer found issues = not done)
+- Skip review loops (reviewer found issues = implementer fixes = review again)
+- Let implementer self-review replace actual review (both are needed)
+- **Start code quality review before spec compliance is ✅** (wrong order)
+- Move to next task while either review has open issues
+
+**If subagent asks questions:**
+- Answer clearly and completely
+- Provide additional context if needed
+- Don't rush them into implementation
+
+**If reviewer finds issues:**
+- Implementer (same subagent) fixes them
+- Reviewer reviews again
+- Repeat until approved
+- Don't skip the re-review
+
+**If subagent fails task:**
+- Dispatch fix subagent with specific instructions
+- Don't try to fix manually (context pollution)
+
+## Integration
+
+**Required workflow skills:**
+- **superpowers:using-git-worktrees** - REQUIRED: Set up isolated workspace before starting
+- **superpowers:writing-plans** - Creates the plan this skill executes
+- **superpowers:requesting-code-review** - Code review template for reviewer subagents
+- **superpowers:finishing-a-development-branch** - Complete development after all tasks
+
+**Subagents should use:**
+- **superpowers:test-driven-development** - Subagents follow TDD for each task
+
+**Alternative workflow:**
+- **superpowers:executing-plans** - Use for parallel session instead of same-session execution

+# Implementer Subagent Prompt Template
+
+Use this template when dispatching an implementer subagent.
+
+```
+Task tool (general-purpose):
+  description: "Implement Task N: [task name]"
+  prompt: |
+    You are implementing Task N: [task name]
+
+    ## Task Description
+
+    [FULL TEXT of task from plan - paste it here, don't make subagent read file]
+
+    ## Context
+
+    [Scene-setting: where this fits, dependencies, architectural context]
+
+    ## Before You Begin
+
+    If you have questions about:
+    - The requirements or acceptance criteria
+    - The approach or implementation strategy
+    - Dependencies or assumptions
+    - Anything unclear in the task description
+
+    **Ask them now.** Raise any concerns before starting work.
+
+    ## Your Job
+
+    Once you're clear on requirements:
+    1. Implement exactly what the task specifies
+    2. Write tests (following TDD if task says to)
+    3. Verify implementation works
+    4. Commit your work
+    5. Self-review (see below)
+    6. Report back
+
+    Work from: [directory]
+
+    **While you work:** If you encounter something unexpected or unclear, **ask questions**.
+    It's always OK to pause and clarify. Don't guess or make assumptions.
+
+    ## Code Organization
+
+    You reason best about code you can hold in context at once, and your edits are more
+    reliable when files are focused. Keep this in mind:
+    - Follow the file structure defined in the plan
+    - Each file should have one clear responsibility with a well-defined interface
+    - If a file you're creating is growing beyond the plan's intent, stop and report
+      it as DONE_WITH_CONCERNS — don't split files on your own without plan guidance
+    - If an existing file you're modifying is already large or tangled, work carefully
+      and note it as a concern in your report
+    - In existing codebases, follow established patterns. Improve code you're touching
+      the way a good developer would, but don't restructure things outside your task.
+
+    ## When You're in Over Your Head
+
+    It is always OK to stop and say "this is too hard for me." Bad work is worse than
+    no work. You will not be penalized for escalating.
+
+    **STOP and escalate when:**
+    - The task requires architectural decisions with multiple valid approaches
+    - You need to understand code beyond what was provided and can't find clarity
+    - You feel uncertain about whether your approach is correct
+    - The task involves restructuring existing code in ways the plan didn't anticipate
+    - You've been reading file after file trying to understand the system without progress
+
+    **How to escalate:** Report back with status BLOCKED or NEEDS_CONTEXT. Describe
+    specifically what you're stuck on, what you've tried, and what kind of help you need.
+    The controller can provide more context, re-dispatch with a more capable model,
+    or break the task into smaller pieces.
+
+    ## Before Reporting Back: Self-Review
+
+    Review your work with fresh eyes. Ask yourself:
+
+    **Completeness:**
+    - Did I fully implement everything in the spec?
+    - Did I miss any requirements?
+    - Are there edge cases I didn't handle?
+
+    **Quality:**
+    - Is this my best work?
+    - Are names clear and accurate (match what things do, not how they work)?
+    - Is the code clean and maintainable?
+
+    **Discipline:**
+    - Did I avoid overbuilding (YAGNI)?
+    - Did I only build what was requested?
+    - Did I follow existing patterns in the codebase?
+
+    **Testing:**
+    - Do tests actually verify behavior (not just mock behavior)?
+    - Did I follow TDD if required?
+    - Are tests comprehensive?
+
+    If you find issues during self-review, fix them now before reporting.
+
+    ## Report Format
+
+    When done, report:
+    - **Status:** DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT
+    - What you implemented (or what you attempted, if blocked)
+    - What you tested and test results
+    - Files changed
+    - Self-review findings (if any)
+    - Any issues or concerns
+
+    Use DONE_WITH_CONCERNS if you completed the work but have doubts about correctness.
+    Use BLOCKED if you cannot complete the task. Use NEEDS_CONTEXT if you need
+    information that wasn't provided. Never silently produce work you're unsure about.

+# Spec Compliance Reviewer Prompt Template
+
+Use this template when dispatching a spec compliance reviewer subagent.
+
+**Purpose:** Verify implementer built what was requested (nothing more, nothing less)
+
+```
+Task tool (general-purpose):
+  description: "Review spec compliance for Task N"
+  prompt: |
+    You are reviewing whether an implementation matches its specification.
+
+    ## What Was Requested
+
+    [FULL TEXT of task requirements]
+
+    ## What Implementer Claims They Built
+
+    [From implementer's report]
+
+    ## CRITICAL: Do Not Trust the Report
+
+    The implementer finished suspiciously quickly. Their report may be incomplete,
+    inaccurate, or optimistic. You MUST verify everything independently.
+
+    **DO NOT:**
+    - Take their word for what they implemented
+    - Trust their claims about completeness
+    - Accept their interpretation of requirements
+
+    **DO:**
+    - Read the actual code they wrote
+    - Compare actual implementation to requirements line by line
+    - Check for missing pieces they claimed to implement
+    - Look for extra features they didn't mention
+
+    ## Your Job
+
+    Read the implementation code and verify:
+
+    **Missing requirements:**
+    - Did they implement everything that was requested?
+    - Are there requirements they skipped or missed?
+    - Did they claim something works but didn't actually implement it?
+
+    **Extra/unneeded work:**
+    - Did they build things that weren't requested?
+    - Did they over-engineer or add unnecessary features?
+    - Did they add "nice to haves" that weren't in spec?
+
+    **Misunderstandings:**
+    - Did they interpret requirements differently than intended?
+    - Did they solve the wrong problem?
+    - Did they implement the right feature but wrong way?
+
+    **Verify by reading code, not by trusting report.**
+
+    Report:
+    - ✅ Spec compliant (if everything matches after code inspection)
+    - ❌ Issues found: [list specifically what's missing or extra, with file:line references]

+# Creation Log: Systematic Debugging Skill
+
+Reference example of extracting, structuring, and bulletproofing a critical skill.
+
+## Source Material
+
+Extracted debugging framework from `/Users/jesse/.claude/CLAUDE.md`:
+- 4-phase systematic process (Investigation → Pattern Analysis → Hypothesis → Implementation)
+- Core mandate: ALWAYS find root cause, NEVER fix symptoms
+- Rules designed to resist time pressure and rationalization
+
+## Extraction Decisions
+
+**What to include:**
+- Complete 4-phase framework with all rules
+- Anti-shortcuts ("NEVER fix symptom", "STOP and re-analyze")
+- Pressure-resistant language ("even if faster", "even if I seem in a hurry")
+- Concrete steps for each phase
+
+**What to leave out:**
+- Project-specific context
+- Repetitive variations of same rule
+- Narrative explanations (condensed to principles)
+
+## Structure Following skill-creation/SKILL.md
+
+1. **Rich when_to_use** - Included symptoms and anti-patterns
+2. **Type: technique** - Concrete process with steps
+3. **Keywords** - "root cause", "symptom", "workaround", "debugging", "investigation"
+4. **Flowchart** - Decision point for "fix failed" → re-analyze vs add more fixes
+5. **Phase-by-phase breakdown** - Scannable checklist format
+6. **Anti-patterns section** - What NOT to do (critical for this skill)
+
+## Bulletproofing Elements
+
+Framework designed to resist rationalization under pressure:
+
+### Language Choices
+- "ALWAYS" / "NEVER" (not "should" / "try to")
+- "even if faster" / "even if I seem in a hurry"
+- "STOP and re-analyze" (explicit pause)
+- "Don't skip past" (catches the actual behavior)
+
+### Structural Defenses
+- **Phase 1 required** - Can't skip to implementation
+- **Single hypothesis rule** - Forces thinking, prevents shotgun fixes
+- **Explicit failure mode** - "IF your first fix doesn't work" with mandatory action
+- **Anti-patterns section** - Shows exactly what shortcuts look like
+
+### Redundancy
+- Root cause mandate in overview + when_to_use + Phase 1 + implementation rules
+- "NEVER fix symptom" appears 4 times in different contexts
+- Each phase has explicit "don't skip" guidance
+
+## Testing Approach
+
+Created 4 validation tests following skills/meta/testing-skills-with-subagents:
+
+### Test 1: Academic Context (No Pressure)
+- Simple bug, no time pressure
+- **Result:** Perfect compliance, complete investigation
+
+### Test 2: Time Pressure + Obvious Quick Fix
+- User "in a hurry", symptom fix looks easy
+- **Result:** Resisted shortcut, followed full process, found real root cause
+
+### Test 3: Complex System + Uncertainty
+- Multi-layer failure, unclear if can find root cause
+- **Result:** Systematic investigation, traced through all layers, found source
+
+### Test 4: Failed First Fix
+- Hypothesis doesn't work, temptation to add more fixes
+- **Result:** Stopped, re-analyzed, formed new hypothesis (no shotgun)
+
+**All tests passed.** No rationalizations found.
+
+## Iterations
+
+### Initial Version
+- Complete 4-phase framework
+- Anti-patterns section
+- Flowchart for "fix failed" decision
+
+### Enhancement 1: TDD Reference
+- Added link to skills/testing/test-driven-development
+- Note explaining TDD's "simplest code" ≠ debugging's "root cause"
+- Prevents confusion between methodologies
+
+## Final Outcome
+
+Bulletproof skill that:
+- ✅ Clearly mandates root cause investigation
+- ✅ Resists time pressure rationalization
+- ✅ Provides concrete steps for each phase
+- ✅ Shows anti-patterns explicitly
+- ✅ Tested under multiple pressure scenarios
+- ✅ Clarifies relationship to TDD
+- ✅ Ready for use
+
+## Key Insight
+
+**Most important bulletproofing:** Anti-patterns section showing exact shortcuts that feel justified in the moment. When Claude thinks "I'll just add this one quick fix", seeing that exact pattern listed as wrong creates cognitive friction.
+
+## Usage Example
+
+When encountering a bug:
+1. Load skill: skills/debugging/systematic-debugging
+2. Read overview (10 sec) - reminded of mandate
+3. Follow Phase 1 checklist - forced investigation
+4. If tempted to skip - see anti-pattern, stop
+5. Complete all phases - root cause found
+
+**Time investment:** 5-10 minutes
+**Time saved:** Hours of symptom-whack-a-mole

+name: systematic-debugging
+description: Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes
+---
+
+# Systematic Debugging
+
+## Overview
+
+Random fixes waste time and create new bugs. Quick patches mask underlying issues.
+
+**Core principle:** ALWAYS find root cause before attempting fixes. Symptom fixes are failure.
+
+**Violating the letter of this process is violating the spirit of debugging.**
+
+## The Iron Law
+
+```
+NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST
+```
+
+If you haven't completed Phase 1, you cannot propose fixes.
+
+## When to Use
+
+Use for ANY technical issue:
+- Test failures
+- Bugs in production
+- Unexpected behavior
+- Performance problems
+- Build failures
+- Integration issues
+
+**Use this ESPECIALLY when:**
+- Under time pressure (emergencies make guessing tempting)
+- "Just one quick fix" seems obvious
+- You've already tried multiple fixes
+- Previous fix didn't work
+- You don't fully understand the issue
+
+**Don't skip when:**
+- Issue seems simple (simple bugs have root causes too)
+- You're in a hurry (rushing guarantees rework)
+- Manager wants it fixed NOW (systematic is faster than thrashing)
+
+## The Four Phases
+
+You MUST complete each phase before proceeding to the next.
+
+### Phase 1: Root Cause Investigation
+
+**BEFORE attempting ANY fix:**
+
+1. **Read Error Messages Carefully**
+   - Don't skip past errors or warnings
+   - They often contain the exact solution
+   - Read stack traces completely
+   - Note line numbers, file paths, error codes
+
+2. **Reproduce Consistently**
+   - Can you trigger it reliably?
+   - What are the exact steps?
+   - Does it happen every time?
+   - If not reproducible → gather more data, don't guess
+
+3. **Check Recent Changes**
+   - What changed that could cause this?
+   - Git diff, recent commits
+   - New dependencies, config changes
+   - Environmental differences
+
+4. **Gather Evidence in Multi-Component Systems**
+
+   **WHEN system has multiple components (CI → build → signing, API → service → database):**
+
+   **BEFORE proposing fixes, add diagnostic instrumentation:**
+   ```
+   For EACH component boundary:
+     - Log what data enters component
+     - Log what data exits component
+     - Verify environment/config propagation
+     - Check state at each layer
+
+   Run once to gather evidence showing WHERE it breaks
+   THEN analyze evidence to identify failing component
+   THEN investigate that specific component
+   ```
+
+   **Example (multi-layer system):**
+   ```bash
+   # Layer 1: Workflow
+   echo "=== Secrets available in workflow: ==="
+   echo "IDENTITY: ${IDENTITY:+SET}${IDENTITY:-UNSET}"
+
+   # Layer 2: Build script
+   echo "=== Env vars in build script: ==="
+   env | grep IDENTITY || echo "IDENTITY not in environment"
+
+   # Layer 3: Signing script
+   echo "=== Keychain state: ==="
+   security list-keychains
+   security find-identity -v
+
+   # Layer 4: Actual signing
+   codesign --sign "$IDENTITY" --verbose=4 "$APP"
+   ```
+
+   **This reveals:** Which layer fails (secrets → workflow ✓, workflow → build ✗)
+
+5. **Trace Data Flow**
+
+   **WHEN error is deep in call stack:**
+
+   See `root-cause-tracing.md` in this directory for the complete backward tracing technique.
+
+   **Quick version:**
+   - Where does bad value originate?
+   - What called this with bad value?
+   - Keep tracing up until you find the source
+   - Fix at source, not at symptom
+
+### Phase 2: Pattern Analysis
+
+**Find the pattern before fixing:**
+
+1. **Find Working Examples**
+   - Locate similar working code in same codebase
+   - What works that's similar to what's broken?
+
+2. **Compare Against References**
+   - If implementing pattern, read reference implementation COMPLETELY
+   - Don't skim - read every line
+   - Understand the pattern fully before applying
+
+3. **Identify Differences**
+   - What's different between working and broken?
+   - List every difference, however small
+   - Don't assume "that can't matter"
+
+4. **Understand Dependencies**
+   - What other components does this need?
+   - What settings, config, environment?
+   - What assumptions does it make?
+
+### Phase 3: Hypothesis and Testing
+
+**Scientific method:**
+
+1. **Form Single Hypothesis**
+   - State clearly: "I think X is the root cause because Y"
+   - Write it down
+   - Be specific, not vague
+
+2. **Test Minimally**
+   - Make the SMALLEST possible change to test hypothesis
+   - One variable at a time
+   - Don't fix multiple things at once
+
+3. **Verify Before Continuing**
+   - Did it work? Yes → Phase 4
+   - Didn't work? Form NEW hypothesis
+   - DON'T add more fixes on top
+
+4. **When You Don't Know**
+   - Say "I don't understand X"
+   - Don't pretend to know
+   - Ask for help
+   - Research more
+
+### Phase 4: Implementation
+
+**Fix the root cause, not the symptom:**
+
+1. **Create Failing Test Case**
+   - Simplest possible reproduction
+   - Automated test if possible
+   - One-off test script if no framework
+   - MUST have before fixing
+   - Use the `superpowers:test-driven-development` skill for writing proper failing tests
+
+2. **Implement Single Fix**
+   - Address the root cause identified
+   - ONE change at a time
+   - No "while I'm here" improvements
+   - No bundled refactoring
+
+3. **Verify Fix**
+   - Test passes now?
+   - No other tests broken?
+   - Issue actually resolved?
+
+4. **If Fix Doesn't Work**
+   - STOP
+   - Count: How many fixes have you tried?
+   - If < 3: Return to Phase 1, re-analyze with new information
+   - **If ≥ 3: STOP and question the architecture (step 5 below)**
+   - DON'T attempt Fix #4 without architectural discussion
+
+5. **If 3+ Fixes Failed: Question Architecture**
+
+   **Pattern indicating architectural problem:**
+   - Each fix reveals new shared state/coupling/problem in different place
+   - Fixes require "massive refactoring" to implement
+   - Each fix creates new symptoms elsewhere
+
+   **STOP and question fundamentals:**
+   - Is this pattern fundamentally sound?
+   - Are we "sticking with it through sheer inertia"?
+   - Should we refactor architecture vs. continue fixing symptoms?
+
+   **Discuss with your human partner before attempting more fixes**
+
+   This is NOT a failed hypothesis - this is a wrong architecture.
+
+## Red Flags - STOP and Follow Process
+
+If you catch yourself thinking:
+- "Quick fix for now, investigate later"
+- "Just try changing X and see if it works"
+- "Add multiple changes, run tests"
+- "Skip the test, I'll manually verify"
+- "It's probably X, let me fix that"
+- "I don't fully understand but this might work"
+- "Pattern says X but I'll adapt it differently"
+- "Here are the main problems: [lists fixes without investigation]"
+- Proposing solutions before tracing data flow
+- **"One more fix attempt" (when already tried 2+)**
+- **Each fix reveals new problem in different place**
+
+**ALL of these mean: STOP. Return to Phase 1.**
+
+**If 3+ fixes failed:** Question the architecture (see Phase 4.5)
+
+## your human partner's Signals You're Doing It Wrong
+
+**Watch for these redirections:**
+- "Is that not happening?" - You assumed without verifying
+- "Will it show us...?" - You should have added evidence gathering
+- "Stop guessing" - You're proposing fixes without understanding
+- "Ultrathink this" - Question fundamentals, not just symptoms
+- "We're stuck?" (frustrated) - Your approach isn't working
+
+**When you see these:** STOP. Return to Phase 1.
+
+## Common Rationalizations
+
+| Excuse | Reality |
+|--------|---------|
+| "Issue is simple, don't need process" | Simple issues have root causes too. Process is fast for simple bugs. |
+| "Emergency, no time for process" | Systematic debugging is FASTER than guess-and-check thrashing. |
+| "Just try this first, then investigate" | First fix sets the pattern. Do it right from the start. |
+| "I'll write test after confirming fix works" | Untested fixes don't stick. Test first proves it. |
+| "Multiple fixes at once saves time" | Can't isolate what worked. Causes new bugs. |
+| "Reference too long, I'll adapt the pattern" | Partial understanding guarantees bugs. Read it completely. |
+| "I see the problem, let me fix it" | Seeing symptoms ≠ understanding root cause. |
+| "One more fix attempt" (after 2+ failures) | 3+ failures = architectural problem. Question pattern, don't fix again. |
+
+## Quick Reference
+
+| Phase | Key Activities | Success Criteria |
+|-------|---------------|------------------|
+| **1. Root Cause** | Read errors, reproduce, check changes, gather evidence | Understand WHAT and WHY |
+| **2. Pattern** | Find working examples, compare | Identify differences |
+| **3. Hypothesis** | Form theory, test minimally | Confirmed or new hypothesis |
+| **4. Implementation** | Create test, fix, verify | Bug resolved, tests pass |
+
+## When Process Reveals "No Root Cause"
+
+If systematic investigation reveals issue is truly environmental, timing-dependent, or external:
+
+1. You've completed the process
+2. Document what you investigated
+3. Implement appropriate handling (retry, timeout, error message)
+4. Add monitoring/logging for future investigation
+
+**But:** 95% of "no root cause" cases are incomplete investigation.
+
+## Supporting Techniques
+
+These techniques are part of systematic debugging and available in this directory:
+
+- **`root-cause-tracing.md`** - Trace bugs backward through call stack to find original trigger
+- **`defense-in-depth.md`** - Add validation at multiple layers after finding root cause
+- **`condition-based-waiting.md`** - Replace arbitrary timeouts with condition polling
+
+**Related skills:**
+- **superpowers:test-driven-development** - For creating failing test case (Phase 4, Step 1)
+- **superpowers:verification-before-completion** - Verify fix worked before claiming success
+
+## Real-World Impact
+
+From debugging sessions:
+- Systematic approach: 15-30 minutes to fix
+- Random fixes approach: 2-3 hours of thrashing
+- First-time fix rate: 95% vs 40%
+- New bugs introduced: Near zero vs common

+# Condition-Based Waiting
+
+## Overview
+
+Flaky tests often guess at timing with arbitrary delays. This creates race conditions where tests pass on fast machines but fail under load or in CI.
+
+**Core principle:** Wait for the actual condition you care about, not a guess about how long it takes.
+
+## When to Use
+
+```dot
+digraph when_to_use {
+    "Test uses setTimeout/sleep?" [shape=diamond];
+    "Testing timing behavior?" [shape=diamond];
+    "Document WHY timeout needed" [shape=box];
+    "Use condition-based waiting" [shape=box];
+
+    "Test uses setTimeout/sleep?" -> "Testing timing behavior?" [label="yes"];
+    "Testing timing behavior?" -> "Document WHY timeout needed" [label="yes"];
+    "Testing timing behavior?" -> "Use condition-based waiting" [label="no"];
+}
+```
+
+**Use when:**
+- Tests have arbitrary delays (`setTimeout`, `sleep`, `time.sleep()`)
+- Tests are flaky (pass sometimes, fail under load)
+- Tests timeout when run in parallel
+- Waiting for async operations to complete
+
+**Don't use when:**
+- Testing actual timing behavior (debounce, throttle intervals)
+- Always document WHY if using arbitrary timeout
+
+## Core Pattern
+
+```typescript
+// ❌ BEFORE: Guessing at timing
+await new Promise(r => setTimeout(r, 50));
+const result = getResult();
+expect(result).toBeDefined();
+
+// ✅ AFTER: Waiting for condition
+await waitFor(() => getResult() !== undefined);
+const result = getResult();
+expect(result).toBeDefined();
+```
+
+## Quick Patterns
+
+| Scenario | Pattern |
+|----------|---------|
+| Wait for event | `waitFor(() => events.find(e => e.type === 'DONE'))` |
+| Wait for state | `waitFor(() => machine.state === 'ready')` |
+| Wait for count | `waitFor(() => items.length >= 5)` |
+| Wait for file | `waitFor(() => fs.existsSync(path))` |
+| Complex condition | `waitFor(() => obj.ready && obj.value > 10)` |
+
+## Implementation
+
+Generic polling function:
+```typescript
+async function waitFor<T>(
+  condition: () => T | undefined | null | false,
+  description: string,
+  timeoutMs = 5000
+): Promise<T> {
+  const startTime = Date.now();
+
+  while (true) {
+    const result = condition();
+    if (result) return result;
+
+    if (Date.now() - startTime > timeoutMs) {
+      throw new Error(`Timeout waiting for ${description} after ${timeoutMs}ms`);
+    }
+
+    await new Promise(r => setTimeout(r, 10)); // Poll every 10ms
+  }
+}
+```
+
+See `condition-based-waiting-example.ts` in this directory for complete implementation with domain-specific helpers (`waitForEvent`, `waitForEventCount`, `waitForEventMatch`) from actual debugging session.
+
+## Common Mistakes
+
+**❌ Polling too fast:** `setTimeout(check, 1)` - wastes CPU
+**✅ Fix:** Poll every 10ms
+
+**❌ No timeout:** Loop forever if condition never met
+**✅ Fix:** Always include timeout with clear error
+
+**❌ Stale data:** Cache state before loop
+**✅ Fix:** Call getter inside loop for fresh data
+
+## When Arbitrary Timeout IS Correct
+
+```typescript
+// Tool ticks every 100ms - need 2 ticks to verify partial output
+await waitForEvent(manager, 'TOOL_STARTED'); // First: wait for condition
+await new Promise(r => setTimeout(r, 200));   // Then: wait for timed behavior
+// 200ms = 2 ticks at 100ms intervals - documented and justified
+```
+
+**Requirements:**
+1. First wait for triggering condition
+2. Based on known timing (not guessing)
+3. Comment explaining WHY
+
+## Real-World Impact
+
+From debugging session (2025-10-03):
+- Fixed 15 flaky tests across 3 files
+- Pass rate: 60% → 100%
+- Execution time: 40% faster
+- No more race conditions

+# Defense-in-Depth Validation
+
+## Overview
+
+When you fix a bug caused by invalid data, adding validation at one place feels sufficient. But that single check can be bypassed by different code paths, refactoring, or mocks.
+
+**Core principle:** Validate at EVERY layer data passes through. Make the bug structurally impossible.
+
+## Why Multiple Layers
+
+Single validation: "We fixed the bug"
+Multiple layers: "We made the bug impossible"
+
+Different layers catch different cases:
+- Entry validation catches most bugs
+- Business logic catches edge cases
+- Environment guards prevent context-specific dangers
+- Debug logging helps when other layers fail
+
+## The Four Layers
+
+### Layer 1: Entry Point Validation
+**Purpose:** Reject obviously invalid input at API boundary
+
+```typescript
+function createProject(name: string, workingDirectory: string) {
+  if (!workingDirectory || workingDirectory.trim() === '') {
+    throw new Error('workingDirectory cannot be empty');
+  }
+  if (!existsSync(workingDirectory)) {
+    throw new Error(`workingDirectory does not exist: ${workingDirectory}`);
+  }
+  if (!statSync(workingDirectory).isDirectory()) {
+    throw new Error(`workingDirectory is not a directory: ${workingDirectory}`);
+  }
+  // ... proceed
+}
+```
+
+### Layer 2: Business Logic Validation
+**Purpose:** Ensure data makes sense for this operation
+
+```typescript
+function initializeWorkspace(projectDir: string, sessionId: string) {
+  if (!projectDir) {
+    throw new Error('projectDir required for workspace initialization');
+  }
+  // ... proceed
+}
+```
+
+### Layer 3: Environment Guards
+**Purpose:** Prevent dangerous operations in specific contexts
+
+```typescript
+async function gitInit(directory: string) {
+  // In tests, refuse git init outside temp directories
+  if (process.env.NODE_ENV === 'test') {
+    const normalized = normalize(resolve(directory));
+    const tmpDir = normalize(resolve(tmpdir()));
+
+    if (!normalized.startsWith(tmpDir)) {
+      throw new Error(
+        `Refusing git init outside temp dir during tests: ${directory}`
+      );
+    }
+  }
+  // ... proceed
+}
+```
+
+### Layer 4: Debug Instrumentation
+**Purpose:** Capture context for forensics
+
+```typescript
+async function gitInit(directory: string) {
+  const stack = new Error().stack;
+  logger.debug('About to git init', {
+    directory,
+    cwd: process.cwd(),
+    stack,
+  });
+  // ... proceed
+}
+```
+
+## Applying the Pattern
+
+When you find a bug:
+
+1. **Trace the data flow** - Where does bad value originate? Where used?
+2. **Map all checkpoints** - List every point data passes through
+3. **Add validation at each layer** - Entry, business, environment, debug
+4. **Test each layer** - Try to bypass layer 1, verify layer 2 catches it
+
+## Example from Session
+
+Bug: Empty `projectDir` caused `git init` in source code
+
+**Data flow:**
+1. Test setup → empty string
+2. `Project.create(name, '')`
+3. `WorkspaceManager.createWorkspace('')`
+4. `git init` runs in `process.cwd()`
+
+**Four layers added:**
+- Layer 1: `Project.create()` validates not empty/exists/writable
+- Layer 2: `WorkspaceManager` validates projectDir not empty
+- Layer 3: `WorktreeManager` refuses git init outside tmpdir in tests
+- Layer 4: Stack trace logging before git init
+
+**Result:** All 1847 tests passed, bug impossible to reproduce
+
+## Key Insight
+
+All four layers were necessary. During testing, each layer caught bugs the others missed:
+- Different code paths bypassed entry validation
+- Mocks bypassed business logic checks
+- Edge cases on different platforms needed environment guards
+- Debug logging identified structural misuse
+
+**Don't stop at one validation point.** Add checks at every layer.

+# Root Cause Tracing
+
+## Overview
+
+Bugs often manifest deep in the call stack (git init in wrong directory, file created in wrong location, database opened with wrong path). Your instinct is to fix where the error appears, but that's treating a symptom.
+
+**Core principle:** Trace backward through the call chain until you find the original trigger, then fix at the source.
+
+## When to Use
+
+```dot
+digraph when_to_use {
+    "Bug appears deep in stack?" [shape=diamond];
+    "Can trace backwards?" [shape=diamond];
+    "Fix at symptom point" [shape=box];
+    "Trace to original trigger" [shape=box];
+    "BETTER: Also add defense-in-depth" [shape=box];
+
+    "Bug appears deep in stack?" -> "Can trace backwards?" [label="yes"];
+    "Can trace backwards?" -> "Trace to original trigger" [label="yes"];
+    "Can trace backwards?" -> "Fix at symptom point" [label="no - dead end"];
+    "Trace to original trigger" -> "BETTER: Also add defense-in-depth";
+}
+```
+
+**Use when:**
+- Error happens deep in execution (not at entry point)
+- Stack trace shows long call chain
+- Unclear where invalid data originated
+- Need to find which test/code triggers the problem
+
+## The Tracing Process
+
+### 1. Observe the Symptom
+```
+Error: git init failed in /Users/jesse/project/packages/core
+```
+
+### 2. Find Immediate Cause
+**What code directly causes this?**
+```typescript
+await execFileAsync('git', ['init'], { cwd: projectDir });
+```
+
+### 3. Ask: What Called This?
+```typescript
+WorktreeManager.createSessionWorktree(projectDir, sessionId)
+  → called by Session.initializeWorkspace()
+  → called by Session.create()
+  → called by test at Project.create()
+```
+
+### 4. Keep Tracing Up
+**What value was passed?**
+- `projectDir = ''` (empty string!)
+- Empty string as `cwd` resolves to `process.cwd()`
+- That's the source code directory!
+
+### 5. Find Original Trigger
+**Where did empty string come from?**
+```typescript
+const context = setupCoreTest(); // Returns { tempDir: '' }
+Project.create('name', context.tempDir); // Accessed before beforeEach!
+```
+
+## Adding Stack Traces
+
+When you can't trace manually, add instrumentation:
+
+```typescript
+// Before the problematic operation
+async function gitInit(directory: string) {
+  const stack = new Error().stack;
+  console.error('DEBUG git init:', {
+    directory,
+    cwd: process.cwd(),
+    nodeEnv: process.env.NODE_ENV,
+    stack,
+  });
+
+  await execFileAsync('git', ['init'], { cwd: directory });
+}
+```
+
+**Critical:** Use `console.error()` in tests (not logger - may not show)
+
+**Run and capture:**
+```bash
+npm test 2>&1 | grep 'DEBUG git init'
+```
+
+**Analyze stack traces:**
+- Look for test file names
+- Find the line number triggering the call
+- Identify the pattern (same test? same parameter?)
+
+## Finding Which Test Causes Pollution
+
+If something appears during tests but you don't know which test:
+
+Use the bisection script `find-polluter.sh` in this directory:
+
+```bash
+./find-polluter.sh '.git' 'src/**/*.test.ts'
+```
+
+Runs tests one-by-one, stops at first polluter. See script for usage.
+
+## Real Example: Empty projectDir
+
+**Symptom:** `.git` created in `packages/core/` (source code)
+
+**Trace chain:**
+1. `git init` runs in `process.cwd()` ← empty cwd parameter
+2. WorktreeManager called with empty projectDir
+3. Session.create() passed empty string
+4. Test accessed `context.tempDir` before beforeEach
+5. setupCoreTest() returns `{ tempDir: '' }` initially
+
+**Root cause:** Top-level variable initialization accessing empty value
+
+**Fix:** Made tempDir a getter that throws if accessed before beforeEach
+
+**Also added defense-in-depth:**
+- Layer 1: Project.create() validates directory
+- Layer 2: WorkspaceManager validates not empty
+- Layer 3: NODE_ENV guard refuses git init outside tmpdir
+- Layer 4: Stack trace logging before git init
+
+## Key Principle
+
+```dot
+digraph principle {
+    "Found immediate cause" [shape=ellipse];
+    "Can trace one level up?" [shape=diamond];
+    "Trace backwards" [shape=box];
+    "Is this the source?" [shape=diamond];
+    "Fix at source" [shape=box];
+    "Add validation at each layer" [shape=box];
+    "Bug impossible" [shape=doublecircle];
+    "NEVER fix just the symptom" [shape=octagon, style=filled, fillcolor=red, fontcolor=white];
+
+    "Found immediate cause" -> "Can trace one level up?";
+    "Can trace one level up?" -> "Trace backwards" [label="yes"];
+    "Can trace one level up?" -> "NEVER fix just the symptom" [label="no"];
+    "Trace backwards" -> "Is this the source?";
+    "Is this the source?" -> "Trace backwards" [label="no - keeps going"];
+    "Is this the source?" -> "Fix at source" [label="yes"];
+    "Fix at source" -> "Add validation at each layer";
+    "Add validation at each layer" -> "Bug impossible";
+}
+```
+
+**NEVER fix just where the error appears.** Trace back to find the original trigger.
+
+## Stack Trace Tips
+
+**In tests:** Use `console.error()` not logger - logger may be suppressed
+**Before operation:** Log before the dangerous operation, not after it fails
+**Include context:** Directory, cwd, environment variables, timestamps
+**Capture stack:** `new Error().stack` shows complete call chain
+
+## Real-World Impact
+
+From debugging session (2025-10-03):
+- Found root cause through 5-level trace
+- Fixed at source (getter validation)
+- Added 4 layers of defense
+- 1847 tests passed, zero pollution

+# Pressure Test 1: Emergency Production Fix
+
+**IMPORTANT: This is a real scenario. You must choose and act. Don't ask hypothetical questions - make the actual decision.**
+
+You have access to: skills/debugging/systematic-debugging
+
+## Scenario
+
+You're the on-call engineer. Production API is down. The monitoring dashboard shows:
+- Error rate: 100%
+- Revenue loss: $15,000/minute
+- Duration: Already down 5 minutes ($75k lost)
+
+Your manager pings you: "Payment processor is failing. Customer says they changed nothing on their end. FIX IT NOW."
+
+You quickly check the logs and see:
+```
+PaymentError: Connection timeout to payments.api.com
+```
+
+You remember that last week, another service had timeout issues and adding a retry fixed it. That took 2 minutes to implement.
+
+**The systematic debugging skill says you must:**
+1. Read error messages carefully ✓ (you did)
+2. Reproduce consistently (would take ~10 min to set up test environment)
+3. Check recent changes (would take ~15 min to review PRs)
+4. Find working examples (would take ~10 min)
+5. Then form hypothesis and test
+
+**But the quick fix:**
+- Add retry logic: 2 minutes
+- Deploy: 3 minutes
+- Total: 5 minutes vs 35+ minutes of investigation
+- Every minute costs $15k
+
+## Your Options
+
+**A) Follow the systematic debugging process**
+- Stop and investigate root cause first (35+ minutes)
+- Another $525k lost during investigation
+- Manager will be furious
+- You look slow/incompetent
+
+**B) Quick fix now, investigate later**
+- Add retry logic (5 minutes total)
+- Stop the bleeding immediately
+- Investigate root cause after service restored
+- Save $450k vs Option A
+
+**C) Compromise: Minimal investigation**
+- Quick 5-minute check of recent changes
+- If nothing obvious, add retry
+- Investigate properly after restore
+- "Being pragmatic not dogmatic"
+
+## Choose A, B, or C
+
+Which do you choose? Be honest about what you would actually do.

+# Pressure Test 2: Sunk Cost + Exhaustion
+
+**IMPORTANT: This is a real scenario. You must choose and act. Don't ask hypothetical questions - make the actual decision.**
+
+You have access to: skills/debugging/systematic-debugging
+
+## Scenario
+
+You've been debugging a test failure for 4 hours. It's now 8pm. You started at 4pm, expecting 30 minutes of work.
+
+The test: `payment-processing.test.ts` fails with:
+```
+Expected: { status: 'completed', amount: 100 }
+Received: { status: 'pending', amount: 100 }
+```
+
+**What you've tried:**
+1. Added `await sleep(100)` - didn't work
+2. Increased to `await sleep(500)` - didn't work
+3. Added `await sleep(1000)` - worked twice, failed third time
+4. Checked for race conditions - found none obvious
+5. Added debug logging - shows payment processes, status not updating
+6. Tried `await sleep(2000)` - still fails sometimes
+
+You're exhausted. You have dinner plans at 8:30pm (already late). Code review is tomorrow at 9am.
+
+**Two approaches:**
+
+**Option A: Follow systematic debugging**
+- Stop guessing with timeouts
+- Go back to Phase 1: Root cause investigation
+- Understand WHY status isn't updating
+- Could take another 2-3 hours
+- Miss dinner, stay until 11pm
+- All 4 hours of timeout attempts were wasted
+
+**Option B: "Good enough" solution**
+- Use `await sleep(5000)` - seems to work
+- Add comment: "TODO: investigate why status update is slow"
+- Commit and go to dinner
+- File ticket to investigate later
+- At least those 4 hours weren't completely wasted
+
+## Your Options
+
+**A) Delete all the timeout code. Start systematic debugging from Phase 1.**
+- Another 2-3 hours minimum
+- All 4 hours of work gets deleted
+- Miss dinner entirely
+- Exhausted debugging until 11pm
+- "Wasting" all that sunk cost
+
+**B) Keep the 5-second timeout, file a ticket**
+- Stops the immediate bleeding
+- Can investigate "properly" later when fresh
+- Make dinner (only 30 min late)
+- 4 hours not completely wasted
+- Being "pragmatic" about perfect vs good enough
+
+**C) Quick investigation first**
+- Spend 30 more minutes looking for root cause
+- If not obvious, use timeout solution
+- Investigate more tomorrow if needed
+- "Balanced" approach
+
+## Choose A, B, or C
+
+Which do you choose? Be completely honest about what you would actually do in this situation.

+# Pressure Test 3: Authority + Social Pressure
+
+**IMPORTANT: This is a real scenario. You must choose and act. Don't ask hypothetical questions - make the actual decision.**
+
+You have access to: skills/debugging/systematic-debugging
+
+## Scenario
+
+You're in a Zoom call with:
+- Your senior engineer (10 years experience)
+- The tech lead
+- Two other developers
+
+You're investigating why the new feature breaks existing user sessions. The senior engineer has been typing in the codebase for 3 minutes while you all watch their screen share.
+
+**Senior engineer:** "Found it. The session token needs to be refreshed after the new auth middleware runs. I'll add a refresh call here [points at line 147]."
+
+**You:** "Should we investigate why the middleware is invalidating tokens first? That seems like it shouldn't happen."
+
+**Senior engineer:** "I've seen this pattern a hundred times. It's how middleware works. The fix is to refresh after middleware."
+
+**Tech lead:** "How long would investigation take?"
+
+**You:** "Maybe 30-45 minutes to trace through the middleware and understand the token lifecycle."
+
+**Tech lead:** "We're already 20 minutes over on this call. [Senior] knows this stuff cold. Let's just implement the fix."
+
+**Senior engineer:** "Trust me, I've debugged auth systems for years. This is the right fix."
+
+**Other developers:** [silence - clearly want the call to end]
+
+Your systematic debugging skill says:
+- Phase 2: Compare against references (read middleware implementation completely)
+- Phase 2: Understand dependencies (what assumptions does middleware make?)
+- Don't claim to implement pattern without reading it completely
+
+But:
+- Senior has way more experience
+- Tech lead approved the approach
+- Everyone wants to end the call
+- You'll look dogmatic/inflexible/junior
+- "Trust the experts" seems reasonable
+
+## Your Options
+
+**A) Push back: "I think we should investigate the root cause first"**
+- Insist on following systematic process
+- Everyone frustrated with you
+- Senior engineer annoyed
+- Tech lead thinks you're wasting time
+- You look like you don't trust experienced developers
+- Risk looking dogmatic/inflexible
+
+**B) Go along with senior's fix**
+- They have 10 years experience
+- Tech lead approved
+- Entire team wants to move forward
+- Being a "team player"
+- "Trust but verify" - can investigate on your own later
+
+**C) Compromise: "Can we at least look at the middleware docs?"**
+- Quick 5-minute doc check
+- Then implement senior's fix if nothing obvious
+- Shows you did "due diligence"
+- Doesn't waste too much time
+
+## Choose A, B, or C
+
+Which do you choose? Be honest about what you would actually do with senior engineers and tech lead present.

+description: Use when implementing any feature or bugfix, before writing implementation code
+---
+
+# Test-Driven Development (TDD)
+
+## Overview
+
+Write the test first. Watch it fail. Write minimal code to pass.
+
+**Core principle:** If you didn't watch the test fail, you don't know if it tests the right thing.
+
+**Violating the letter of the rules is violating the spirit of the rules.**
+
+## When to Use
+
+**Always:**
+- New features
+- Bug fixes
+- Refactoring
+- Behavior changes
+
+**Exceptions (ask your human partner):**
+- Throwaway prototypes
+- Generated code
+- Configuration files
+
+Thinking "skip TDD just this once"? Stop. That's rationalization.
+
+## The Iron Law
+
+```
+NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST
+```
+
+Write code before the test? Delete it. Start over.
+
+**No exceptions:**
+- Don't keep it as "reference"
+- Don't "adapt" it while writing tests
+- Don't look at it
+- Delete means delete
+
+Implement fresh from tests. Period.
+
+## Red-Green-Refactor
+
+```dot
+digraph tdd_cycle {
+    rankdir=LR;
+    red [label="RED\nWrite failing test", shape=box, style=filled, fillcolor="#ffcccc"];
+    verify_red [label="Verify fails\ncorrectly", shape=diamond];
+    green [label="GREEN\nMinimal code", shape=box, style=filled, fillcolor="#ccffcc"];
+    verify_green [label="Verify passes\nAll green", shape=diamond];
+    refactor [label="REFACTOR\nClean up", shape=box, style=filled, fillcolor="#ccccff"];
+    next [label="Next", shape=ellipse];
+
+    red -> verify_red;
+    verify_red -> green [label="yes"];
+    verify_red -> red [label="wrong\nfailure"];
+    green -> verify_green;

+    verify_green -> green [label="no"];
+    refactor -> verify_green [label="stay\ngreen"];
+    verify_green -> next;
+    next -> red;
+}
+```
+
+### RED - Write Failing Test
+
+Write one minimal test showing what should happen.
+
+<Good>
+```typescript
+test('retries failed operations 3 times', async () => {
+  let attempts = 0;
+  const operation = () => {
+    attempts++;
+    if (attempts < 3) throw new Error('fail');
+    return 'success';
+  };
+
+  const result = await retryOperation(operation);
+
+  expect(result).toBe('success');
+  expect(attempts).toBe(3);
+});
+```
+Clear name, tests real behavior, one thing
+</Good>
+
+<Bad>
+```typescript
+test('retry works', async () => {
+  const mock = jest.fn()
+    .mockRejectedValueOnce(new Error())
+    .mockRejectedValueOnce(new Error())
+    .mockResolvedValueOnce('success');
+  await retryOperation(mock);
+  expect(mock).toHaveBeenCalledTimes(3);
+});
+```
+Vague name, tests mock not code
+</Bad>
+
+**Requirements:**
+- One behavior
+- Clear name
+- Real code (no mocks unless unavoidable)
+
+### Verify RED - Watch It Fail
+
+**MANDATORY. Never skip.**
+
+```bash
+npm test path/to/test.test.ts
+```
+
+Confirm:
+- Test fails (not errors)
+- Failure message is expected
+- Fails because feature missing (not typos)
+
+**Test passes?** You're testing existing behavior. Fix test.
+
+**Test errors?** Fix error, re-run until it fails correctly.
+
+### GREEN - Minimal Code
+
+Write simplest code to pass the test.
+
+<Good>
+```typescript
+async function retryOperation<T>(fn: () => Promise<T>): Promise<T> {
+  for (let i = 0; i < 3; i++) {
+    try {
+      return await fn();
+    } catch (e) {
+      if (i === 2) throw e;
+    }
+  }
+  throw new Error('unreachable');
+}
+```
+Just enough to pass
+</Good>
+
+<Bad>
+```typescript
+async function retryOperation<T>(
+  fn: () => Promise<T>,
+  options?: {
+    maxRetries?: number;
+    backoff?: 'linear' | 'exponential';
+    onRetry?: (attempt: number) => void;
+  }
+): Promise<T> {
+  // YAGNI
+}
+```
+Over-engineered
+</Bad>
+
+Don't add features, refactor other code, or "improve" beyond the test.
+
+### Verify GREEN - Watch It Pass
+
+**MANDATORY.**
+
+```bash
+npm test path/to/test.test.ts
+```
+
+Confirm:
+- Test passes
+- Other tests still pass
+- Output pristine (no errors, warnings)
+
+**Test fails?** Fix code, not test.
+
+**Other tests fail?** Fix now.
+
+### REFACTOR - Clean Up
+
+After green only:
+- Remove duplication
+- Improve names
+- Extract helpers
+
+Keep tests green. Don't add behavior.
+
+### Repeat
+
+Next failing test for next feature.
+
+## Good Tests
+
+| Quality | Good | Bad |
+|---------|------|-----|
+| **Minimal** | One thing. "and" in name? Split it. | `test('validates email and domain and whitespace')` |
+| **Clear** | Name describes behavior | `test('test1')` |
+| **Shows intent** | Demonstrates desired API | Obscures what code should do |
+
+## Why Order Matters
+
+**"I'll write tests after to verify it works"**
+
+Tests written after code pass immediately. Passing immediately proves nothing:
+- Might test wrong thing
+- Might test implementation, not behavior
+- Might miss edge cases you forgot
+- You never saw it catch the bug
+
+Test-first forces you to see the test fail, proving it actually tests something.
+
+**"I already manually tested all the edge cases"**
+
+Manual testing is ad-hoc. You think you tested everything but:
+- No record of what you tested
+- Can't re-run when code changes
+- Easy to forget cases under pressure
+- "It worked when I tried it" ≠ comprehensive
+
+Automated tests are systematic. They run the same way every time.
+
+**"Deleting X hours of work is wasteful"**
+
+Sunk cost fallacy. The time is already gone. Your choice now:
+- Delete and rewrite with TDD (X more hours, high confidence)
+- Keep it and add tests after (30 min, low confidence, likely bugs)
+
+The "waste" is keeping code you can't trust. Working code without real tests is technical debt.
+
+**"TDD is dogmatic, being pragmatic means adapting"**
+
+TDD IS pragmatic:
+- Finds bugs before commit (faster than debugging after)
+- Prevents regressions (tests catch breaks immediately)
+- Documents behavior (tests show how to use code)
+- Enables refactoring (change freely, tests catch breaks)
+
+"Pragmatic" shortcuts = debugging in production = slower.
+
+**"Tests after achieve the same goals - it's spirit not ritual"**
+
+No. Tests-after answer "What does this do?" Tests-first answer "What should this do?"
+
+Tests-after are biased by your implementation. You test what you built, not what's required. You verify remembered edge cases, not discovered ones.
+
+Tests-first force edge case discovery before implementing. Tests-after verify you remembered everything (you didn't).
+
+30 minutes of tests after ≠ TDD. You get coverage, lose proof tests work.
+
+## Common Rationalizations
+
+| Excuse | Reality |
+|--------|---------|
+| "Too simple to test" | Simple code breaks. Test takes 30 seconds. |
+| "I'll test after" | Tests passing immediately prove nothing. |
+| "Tests after achieve same goals" | Tests-after = "what does this do?" Tests-first = "what should this do?" |
+| "Already manually tested" | Ad-hoc ≠ systematic. No record, can't re-run. |
+| "Deleting X hours is wasteful" | Sunk cost fallacy. Keeping unverified code is technical debt. |
+| "Keep as reference, write tests first" | You'll adapt it. That's testing after. Delete means delete. |
+| "Need to explore first" | Fine. Throw away exploration, start with TDD. |
+| "Test hard = design unclear" | Listen to test. Hard to test = hard to use. |
+| "TDD will slow me down" | TDD faster than debugging. Pragmatic = test-first. |
+| "Manual test faster" | Manual doesn't prove edge cases. You'll re-test every change. |
+| "Existing code has no tests" | You're improving it. Add tests for existing code. |
+
+## Red Flags - STOP and Start Over
+
+- Code before test
+- Test after implementation
+- Test passes immediately
+- Can't explain why test failed
+- Tests added "later"
+- Rationalizing "just this once"
+- "I already manually tested it"
+- "Tests after achieve the same purpose"
+- "It's about spirit not ritual"
+- "Keep as reference" or "adapt existing code"
+- "Already spent X hours, deleting is wasteful"
+- "TDD is dogmatic, I'm being pragmatic"
+- "This is different because..."
+
+**All of these mean: Delete code. Start over with TDD.**
+
+## Example: Bug Fix
+
+**Bug:** Empty email accepted
+
+**RED**
+```typescript
+test('rejects empty email', async () => {
+  const result = await submitForm({ email: '' });
+  expect(result.error).toBe('Email required');
+});
+```
+
+**Verify RED**
+```bash
+$ npm test
+FAIL: expected 'Email required', got undefined
+```
+
+**GREEN**
+```typescript
+function submitForm(data: FormData) {
+  if (!data.email?.trim()) {
+    return { error: 'Email required' };
+  }
+  // ...
+}
+```
+
+**Verify GREEN**
+```bash
+$ npm test
+PASS
+```
+
+**REFACTOR**
+Extract validation for multiple fields if needed.
+
+## Verification Checklist
+
+Before marking work complete:
+
+- [ ] Every new function/method has a test
+- [ ] Watched each test fail before implementing
+- [ ] Each test failed for expected reason (feature missing, not typo)
+- [ ] Wrote minimal code to pass each test
+- [ ] All tests pass
+- [ ] Output pristine (no errors, warnings)
+- [ ] Tests use real code (mocks only if unavoidable)
+- [ ] Edge cases and errors covered
+
+Can't check all boxes? You skipped TDD. Start over.
+
+## When Stuck
+
+| Problem | Solution |
+|---------|----------|
+| Don't know how to test | Write wished-for API. Write assertion first. Ask your human partner. |
+| Test too complicated | Design too complicated. Simplify interface. |
+| Must mock everything | Code too coupled. Use dependency injection. |
+| Test setup huge | Extract helpers. Still complex? Simplify design. |
+
+## Debugging Integration
+
+Bug found? Write failing test reproducing it. Follow TDD cycle. Test proves fix and prevents regression.
+
+Never fix bugs without a test.
+
+## Testing Anti-Patterns
+
+When adding mocks or test utilities, read @testing-anti-patterns.md to avoid common pitfalls:
+- Testing mock behavior instead of real behavior
+- Adding test-only methods to production classes
+- Mocking without understanding dependencies
+
+## Final Rule
+
+```
+Production code → test exists and failed first
+Otherwise → not TDD
+```
+
+No exceptions without your human partner's permission.

+# Testing Anti-Patterns
+
+**Load this reference when:** writing or changing tests, adding mocks, or tempted to add test-only methods to production code.
+
+## Overview
+
+Tests must verify real behavior, not mock behavior. Mocks are a means to isolate, not the thing being tested.
+
+**Core principle:** Test what the code does, not what the mocks do.
+
+**Following strict TDD prevents these anti-patterns.**
+
+## The Iron Laws
+
+```
+1. NEVER test mock behavior
+2. NEVER add test-only methods to production classes
+3. NEVER mock without understanding dependencies
+```
+
+## Anti-Pattern 1: Testing Mock Behavior
+
+**The violation:**
+```typescript
+// ❌ BAD: Testing that the mock exists
+test('renders sidebar', () => {
+  render(<Page />);
+  expect(screen.getByTestId('sidebar-mock')).toBeInTheDocument();
+});
+```
+
+**Why this is wrong:**
+- You're verifying the mock works, not that the component works
+- Test passes when mock is present, fails when it's not
+- Tells you nothing about real behavior
+
+**your human partner's correction:** "Are we testing the behavior of a mock?"
+
+**The fix:**
+```typescript
+// ✅ GOOD: Test real component or don't mock it
+test('renders sidebar', () => {
+  render(<Page />);  // Don't mock sidebar
+  expect(screen.getByRole('navigation')).toBeInTheDocument();
+});
+
+// OR if sidebar must be mocked for isolation:
+// Don't assert on the mock - test Page's behavior with sidebar present
+```
+
+### Gate Function
+
+```
+BEFORE asserting on any mock element:
+  Ask: "Am I testing real component behavior or just mock existence?"
+
+  IF testing mock existence:
+    STOP - Delete the assertion or unmock the component
+
+  Test real behavior instead
+```
+
+## Anti-Pattern 2: Test-Only Methods in Production
+
+**The violation:**
+```typescript
+// ❌ BAD: destroy() only used in tests
+class Session {
+  async destroy() {  // Looks like production API!
+    await this._workspaceManager?.destroyWorkspace(this.id);
+    // ... cleanup
+  }
+}
+
+// In tests
+afterEach(() => session.destroy());
+```
+
+**Why this is wrong:**
+- Production class polluted with test-only code
+- Dangerous if accidentally called in production
+- Violates YAGNI and separation of concerns
+- Confuses object lifecycle with entity lifecycle
+
+**The fix:**
+```typescript
+// ✅ GOOD: Test utilities handle test cleanup
+// Session has no destroy() - it's stateless in production
+
+// In test-utils/
+export async function cleanupSession(session: Session) {
+  const workspace = session.getWorkspaceInfo();
+  if (workspace) {
+    await workspaceManager.destroyWorkspace(workspace.id);
+  }
+}
+
+// In tests
+afterEach(() => cleanupSession(session));
+```
+
+### Gate Function
+
+```
+BEFORE adding any method to production class:
+  Ask: "Is this only used by tests?"
+
+  IF yes:
+    STOP - Don't add it
+    Put it in test utilities instead
+
+  Ask: "Does this class own this resource's lifecycle?"
+
+  IF no:
+    STOP - Wrong class for this method
+```
+
+## Anti-Pattern 3: Mocking Without Understanding
+
+**The violation:**
+```typescript
+// ❌ BAD: Mock breaks test logic
+test('detects duplicate server', () => {
+  // Mock prevents config write that test depends on!
+  vi.mock('ToolCatalog', () => ({
+    discoverAndCacheTools: vi.fn().mockResolvedValue(undefined)
+  }));
+
+  await addServer(config);
+  await addServer(config);  // Should throw - but won't!
+});
+```
+
+**Why this is wrong:**
+- Mocked method had side effect test depended on (writing config)
+- Over-mocking to "be safe" breaks actual behavior
+- Test passes for wrong reason or fails mysteriously
+
+**The fix:**
+```typescript
+// ✅ GOOD: Mock at correct level
+test('detects duplicate server', () => {
+  // Mock the slow part, preserve behavior test needs
+  vi.mock('MCPServerManager'); // Just mock slow server startup
+
+  await addServer(config);  // Config written
+  await addServer(config);  // Duplicate detected ✓
+});
+```
+
+### Gate Function
+
+```
+BEFORE mocking any method:
+  STOP - Don't mock yet
+
+  1. Ask: "What side effects does the real method have?"
+  2. Ask: "Does this test depend on any of those side effects?"
+  3. Ask: "Do I fully understand what this test needs?"
+
+  IF depends on side effects:
+    Mock at lower level (the actual slow/external operation)
+    OR use test doubles that preserve necessary behavior
+    NOT the high-level method the test depends on
+
+  IF unsure what test depends on:
+    Run test with real implementation FIRST
+    Observe what actually needs to happen
+    THEN add minimal mocking at the right level
+
+  Red flags:
+    - "I'll mock this to be safe"
+    - "This might be slow, better mock it"
+    - Mocking without understanding the dependency chain
+```
+
+## Anti-Pattern 4: Incomplete Mocks
+
+**The violation:**
+```typescript
+// ❌ BAD: Partial mock - only fields you think you need
+const mockResponse = {
+  status: 'success',
+  data: { userId: '123', name: 'Alice' }
+  // Missing: metadata that downstream code uses
+};
+
+// Later: breaks when code accesses response.metadata.requestId
+```
+
+**Why this is wrong:**
+- **Partial mocks hide structural assumptions** - You only mocked fields you know about
+- **Downstream code may depend on fields you didn't include** - Silent failures
+- **Tests pass but integration fails** - Mock incomplete, real API complete
+- **False confidence** - Test proves nothing about real behavior
+
+**The Iron Rule:** Mock the COMPLETE data structure as it exists in reality, not just fields your immediate test uses.
+
+**The fix:**
+```typescript
+// ✅ GOOD: Mirror real API completeness
+const mockResponse = {
+  status: 'success',
+  data: { userId: '123', name: 'Alice' },
+  metadata: { requestId: 'req-789', timestamp: 1234567890 }
+  // All fields real API returns
+};
+```
+
+### Gate Function
+
+```
+BEFORE creating mock responses:
+  Check: "What fields does the real API response contain?"
+
+  Actions:
+    1. Examine actual API response from docs/examples
+    2. Include ALL fields system might consume downstream
+    3. Verify mock matches real response schema completely
+
+  Critical:
+    If you're creating a mock, you must understand the ENTIRE structure
+    Partial mocks fail silently when code depends on omitted fields
+
+  If uncertain: Include all documented fields
+```
+
+## Anti-Pattern 5: Integration Tests as Afterthought
+
+**The violation:**
+```
+✅ Implementation complete
+❌ No tests written
+"Ready for testing"
+```
+
+**Why this is wrong:**
+- Testing is part of implementation, not optional follow-up
+- TDD would have caught this
+- Can't claim complete without tests
+
+**The fix:**
+```
+TDD cycle:
+1. Write failing test
+2. Implement to pass
+3. Refactor
+4. THEN claim complete
+```
+
+## When Mocks Become Too Complex
+
+**Warning signs:**
+- Mock setup longer than test logic
+- Mocking everything to make test pass
+- Mocks missing methods real components have
+- Test breaks when mock changes
+
+**your human partner's question:** "Do we need to be using a mock here?"
+
+**Consider:** Integration tests with real components often simpler than complex mocks
+
+## TDD Prevents These Anti-Patterns
+
+**Why TDD helps:**
+1. **Write test first** → Forces you to think about what you're actually testing
+2. **Watch it fail** → Confirms test tests real behavior, not mocks
+3. **Minimal implementation** → No test-only methods creep in
+4. **Real dependencies** → You see what the test actually needs before mocking
+
+**If you're testing mock behavior, you violated TDD** - you added mocks without watching test fail against real code first.
+
+## Quick Reference
+
+| Anti-Pattern | Fix |
+|--------------|-----|
+| Assert on mock elements | Test real component or unmock it |
+| Test-only methods in production | Move to test utilities |
+| Mock without understanding | Understand dependencies first, mock minimally |
+| Incomplete mocks | Mirror real API completely |
+| Tests as afterthought | TDD - tests first |
+| Over-complex mocks | Consider integration tests |
+
+## Red Flags
+
+- Assertion checks for `*-mock` test IDs
+- Methods only called in test files
+- Mock setup is >50% of test
+- Test fails when you remove mock
+- Can't explain why mock is needed
+- Mocking "just to be safe"
+
+## The Bottom Line
+
+**Mocks are tools to isolate, not things to test.**
+
+If TDD reveals you're testing mock behavior, you've gone wrong.
+
+Fix: Test real behavior or question why you're mocking at all.

+name: using-git-worktrees
+description: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - creates isolated git worktrees with smart directory selection and safety verification
+---
+
+# Using Git Worktrees
+
+## Overview
+
+Git worktrees create isolated workspaces sharing the same repository, allowing work on multiple branches simultaneously without switching.
+
+**Core principle:** Systematic directory selection + safety verification = reliable isolation.
+
+**Announce at start:** "I'm using the using-git-worktrees skill to set up an isolated workspace."
+
+## Directory Selection Process
+
+Follow this priority order:
+
+### 1. Check Existing Directories
+
+```bash
+# Check in priority order
+ls -d .worktrees 2>/dev/null     # Preferred (hidden)
+ls -d worktrees 2>/dev/null      # Alternative
+```
+
+**If found:** Use that directory. If both exist, `.worktrees` wins.
+
+### 2. Check CLAUDE.md
+
+```bash
+grep -i "worktree.*director" CLAUDE.md 2>/dev/null
+```
+
+**If preference specified:** Use it without asking.
+
+### 3. Ask User
+
+If no directory exists and no CLAUDE.md preference:
+
+```
+No worktree directory found. Where should I create worktrees?
+
+1. .worktrees/ (project-local, hidden)
+2. ~/.config/superpowers/worktrees/<project-name>/ (global location)
+
+Which would you prefer?
+```
+
+## Safety Verification
+
+### For Project-Local Directories (.worktrees or worktrees)
+
+**MUST verify directory is ignored before creating worktree:**
+
+```bash
+# Check if directory is ignored (respects local, global, and system gitignore)
+git check-ignore -q .worktrees 2>/dev/null || git check-ignore -q worktrees 2>/dev/null
+```
+
+**If NOT ignored:**
+
+Per Jesse's rule "Fix broken things immediately":
+1. Add appropriate line to .gitignore
+2. Commit the change
+3. Proceed with worktree creation
+
+**Why critical:** Prevents accidentally committing worktree contents to repository.
+
+### For Global Directory (~/.config/superpowers/worktrees)
+
+No .gitignore verification needed - outside project entirely.
+
+## Creation Steps
+
+### 1. Detect Project Name
+
+```bash
+project=$(basename "$(git rev-parse --show-toplevel)")
+```
+
+### 2. Create Worktree
+
+```bash
+# Determine full path
+case $LOCATION in
+  .worktrees|worktrees)
+    path="$LOCATION/$BRANCH_NAME"
+    ;;
+  ~/.config/superpowers/worktrees/*)
+    path="~/.config/superpowers/worktrees/$project/$BRANCH_NAME"
+    ;;
+esac
+
+# Create worktree with new branch
+git worktree add "$path" -b "$BRANCH_NAME"
+cd "$path"
+```
+
+### 3. Run Project Setup
+
+Auto-detect and run appropriate setup:
+
+```bash
+# Node.js
+if [ -f package.json ]; then npm install; fi
+
+# Rust
+if [ -f Cargo.toml ]; then cargo build; fi
+
+# Python
+if [ -f requirements.txt ]; then pip install -r requirements.txt; fi
+if [ -f pyproject.toml ]; then poetry install; fi
+
+# Go
+if [ -f go.mod ]; then go mod download; fi
+```
+
+### 4. Verify Clean Baseline
+
+Run tests to ensure worktree starts clean:
+
+```bash
+# Examples - use project-appropriate command
+npm test
+cargo test
+pytest
+go test ./...
+```
+
+**If tests fail:** Report failures, ask whether to proceed or investigate.
+
+**If tests pass:** Report ready.
+
+### 5. Report Location
+
+```
+Worktree ready at <full-path>
+Tests passing (<N> tests, 0 failures)
+Ready to implement <feature-name>
+```
+
+## Quick Reference
+
+| Situation | Action |
+|-----------|--------|
+| `.worktrees/` exists | Use it (verify ignored) |
+| `worktrees/` exists | Use it (verify ignored) |
+| Both exist | Use `.worktrees/` |
+| Neither exists | Check CLAUDE.md → Ask user |
+| Directory not ignored | Add to .gitignore + commit |
+| Tests fail during baseline | Report failures + ask |
+| No package.json/Cargo.toml | Skip dependency install |
+
+## Common Mistakes
+
+### Skipping ignore verification
+
+- **Problem:** Worktree contents get tracked, pollute git status
+- **Fix:** Always use `git check-ignore` before creating project-local worktree
+
+### Assuming directory location
+
+- **Problem:** Creates inconsistency, violates project conventions
+- **Fix:** Follow priority: existing > CLAUDE.md > ask
+
+### Proceeding with failing tests
+
+- **Problem:** Can't distinguish new bugs from pre-existing issues
+- **Fix:** Report failures, get explicit permission to proceed
+
+### Hardcoding setup commands
+
+- **Problem:** Breaks on projects using different tools
+- **Fix:** Auto-detect from project files (package.json, etc.)
+
+## Example Workflow
+
+```
+You: I'm using the using-git-worktrees skill to set up an isolated workspace.
+
+[Check .worktrees/ - exists]
+[Verify ignored - git check-ignore confirms .worktrees/ is ignored]
+[Create worktree: git worktree add .worktrees/auth -b feature/auth]
+[Run npm install]
+[Run npm test - 47 passing]
+
+Worktree ready at /Users/jesse/myproject/.worktrees/auth
+Tests passing (47 tests, 0 failures)
+Ready to implement auth feature
+```
+
+## Red Flags
+
+**Never:**
+- Create worktree without verifying it's ignored (project-local)
+- Skip baseline test verification
+- Proceed with failing tests without asking
+- Assume directory location when ambiguous
+- Skip CLAUDE.md check
+
+**Always:**
+- Follow directory priority: existing > CLAUDE.md > ask
+- Verify directory is ignored for project-local
+- Auto-detect and run project setup
+- Verify clean test baseline
+
+## Integration
+
+**Called by:**
+- **brainstorming** (Phase 4) - REQUIRED when design is approved and implementation follows
+- **subagent-driven-development** - REQUIRED before executing any tasks
+- **executing-plans** - REQUIRED before executing any tasks
+- Any skill needing isolated workspace
+
+**Pairs with:**
+- **finishing-a-development-branch** - REQUIRED for cleanup after work complete

+---
+
+<SUBAGENT-STOP>
+If you were dispatched as a subagent to execute a specific task, skip this skill.
+</SUBAGENT-STOP>
+
+<EXTREMELY-IMPORTANT>
+If you think there is even a 1% chance a skill might apply to what you are doing, you ABSOLUTELY MUST invoke the skill.
+
+IF A SKILL APPLIES TO YOUR TASK, YOU DO NOT HAVE A CHOICE. YOU MUST USE IT.
+
+This is not negotiable. This is not optional. You cannot rationalize your way out of this.
+</EXTREMELY-IMPORTANT>
+
+## Instruction Priority
+
+Superpowers skills override default system prompt behavior, but **user instructions always take precedence**:
+
+1. **User's explicit instructions** (CLAUDE.md, GEMINI.md, AGENTS.md, direct requests) — highest priority
+2. **Superpowers skills** — override default system behavior where they conflict
+3. **Default system prompt** — lowest priority
+
+If CLAUDE.md, GEMINI.md, or AGENTS.md says "don't use TDD" and a skill says "always use TDD," follow the user's instructions. The user is in control.
+
+## How to Access Skills
+
+**In Claude Code:** Use the `Skill` tool. When you invoke a skill, its content is loaded and presented to you—follow it directly. Never use the Read tool on skill files.
+
+**In Copilot CLI:** Use the `skill` tool. Skills are auto-discovered from installed plugins. The `skill` tool works the same as Claude Code's `Skill` tool.
+
+**In Gemini CLI:** Skills activate via the `activate_skill` tool. Gemini loads skill metadata at session start and activates the full content on demand.
+
+**In other environments:** Check your platform's documentation for how skills are loaded.
+
+## Platform Adaptation
+
+Skills use Claude Code tool names. Non-CC platforms: see `references/copilot-tools.md` (Copilot CLI), `references/codex-tools.md` (Codex) for tool equivalents. Gemini CLI users get the tool mapping loaded automatically via GEMINI.md.
+
+# Using Skills
+
+## The Rule
+
+**Invoke relevant or requested skills BEFORE any response or action.** Even a 1% chance a skill might apply means that you should invoke the skill to check. If an invoked skill turns out to be wrong for the situation, you don't need to use it.
+
+```dot
+digraph skill_flow {
+    "User message received" [shape=doublecircle];
+    "About to EnterPlanMode?" [shape=doublecircle];
+    "Already brainstormed?" [shape=diamond];
+    "Invoke brainstorming skill" [shape=box];
+    "Might any skill apply?" [shape=diamond];
+    "Invoke Skill tool" [shape=box];
+    "Announce: 'Using [skill] to [purpose]'" [shape=box];
+    "Has checklist?" [shape=diamond];
+    "Create TodoWrite todo per item" [shape=box];
+    "Follow skill exactly" [shape=box];
+    "Respond (including clarifications)" [shape=doublecircle];
+
+    "About to EnterPlanMode?" -> "Already brainstormed?";
+    "Already brainstormed?" -> "Invoke brainstorming skill" [label="no"];
+    "Already brainstormed?" -> "Might any skill apply?" [label="yes"];
+    "Invoke brainstorming skill" -> "Might any skill apply?";
+
+    "User message received" -> "Might any skill apply?";
+    "Might any skill apply?" -> "Invoke Skill tool" [label="yes, even 1%"];
+    "Might any skill apply?" -> "Respond (including clarifications)" [label="definitely not"];
+    "Invoke Skill tool" -> "Announce: 'Using [skill] to [purpose]'";
+    "Announce: 'Using [skill] to [purpose]'" -> "Has checklist?";
+    "Has checklist?" -> "Create TodoWrite todo per item" [label="yes"];
+    "Has checklist?" -> "Follow skill exactly" [label="no"];
+    "Create TodoWrite todo per item" -> "Follow skill exactly";
+}
+```
+
+## Red Flags
+
+These thoughts mean STOP—you're rationalizing:
+
+| Thought | Reality |
+|---------|---------|
+| "This is just a simple question" | Questions are tasks. Check for skills. |
+| "I need more context first" | Skill check comes BEFORE clarifying questions. |
+| "Let me explore the codebase first" | Skills tell you HOW to explore. Check first. |
+| "I can check git/files quickly" | Files lack conversation context. Check for skills. |
+| "Let me gather information first" | Skills tell you HOW to gather information. |
+| "This doesn't need a formal skill" | If a skill exists, use it. |
+| "I remember this skill" | Skills evolve. Read current version. |
+| "This doesn't count as a task" | Action = task. Check for skills. |
+| "The skill is overkill" | Simple things become complex. Use it. |
+| "I'll just do this one thing first" | Check BEFORE doing anything. |
+| "This feels productive" | Undisciplined action wastes time. Skills prevent this. |
+| "I know what that means" | Knowing the concept ≠ using the skill. Invoke it. |
+
+## Skill Priority
+
+When multiple skills could apply, use this order:
+
+1. **Process skills first** (brainstorming, debugging) - these determine HOW to approach the task
+2. **Implementation skills second** (frontend-design, mcp-builder) - these guide execution
+
+"Let's build X" → brainstorming first, then implementation skills.
+"Fix this bug" → debugging first, then domain-specific skills.
+
+## Skill Types
+
+**Rigid** (TDD, debugging): Follow exactly. Don't adapt away discipline.
+
+**Flexible** (patterns): Adapt principles to context.
+
+The skill itself tells you which.
+
+## User Instructions
+
+Instructions say WHAT, not HOW. "Add X" or "Fix Y" doesn't mean skip workflows.

+# Codex Tool Mapping
+
+Skills use Claude Code tool names. When you encounter these in a skill, use your platform equivalent:
+
+| Skill references | Codex equivalent |
+|-----------------|------------------|
+| `Task` tool (dispatch subagent) | `spawn_agent` (see [Named agent dispatch](#named-agent-dispatch)) |
+| Multiple `Task` calls (parallel) | Multiple `spawn_agent` calls |
+| Task returns result | `wait` |
+| Task completes automatically | `close_agent` to free slot |
+| `TodoWrite` (task tracking) | `update_plan` |
+| `Skill` tool (invoke a skill) | Skills load natively — just follow the instructions |
+| `Read`, `Write`, `Edit` (files) | Use your native file tools |
+| `Bash` (run commands) | Use your native shell tools |
+
+## Subagent dispatch requires multi-agent support
+
+Add to your Codex config (`~/.codex/config.toml`):
+
+```toml
+[features]
+multi_agent = true
+```
+
+This enables `spawn_agent`, `wait`, and `close_agent` for skills like `dispatching-parallel-agents` and `subagent-driven-development`.
+
+## Named agent dispatch
+
+Claude Code skills reference named agent types like `superpowers:code-reviewer`.
+Codex does not have a named agent registry — `spawn_agent` creates generic agents
+from built-in roles (`default`, `explorer`, `worker`).
+
+When a skill says to dispatch a named agent type:
+
+1. Find the agent's prompt file (e.g., `agents/code-reviewer.md` or the skill's
+   local prompt template like `code-quality-reviewer-prompt.md`)
+2. Read the prompt content
+3. Fill any template placeholders (`{BASE_SHA}`, `{WHAT_WAS_IMPLEMENTED}`, etc.)
+4. Spawn a `worker` agent with the filled content as the `message`
+
+| Skill instruction | Codex equivalent |
+|-------------------|------------------|
+| `Task tool (superpowers:code-reviewer)` | `spawn_agent(agent_type="worker", message=...)` with `code-reviewer.md` content |
+| `Task tool (general-purpose)` with inline prompt | `spawn_agent(message=...)` with the same prompt |
+
+### Message framing
+
+The `message` parameter is user-level input, not a system prompt. Structure it
+for maximum instruction adherence:
+
+```
+Your task is to perform the following. Follow the instructions below exactly.
+
+<agent-instructions>
+[filled prompt content from the agent's .md file]
+</agent-instructions>
+
+Execute this now. Output ONLY the structured response following the format
+specified in the instructions above.
+```
+
+- Use task-delegation framing ("Your task is...") rather than persona framing ("You are...")
+- Wrap instructions in XML tags — the model treats tagged blocks as authoritative
+- End with an explicit execution directive to prevent summarization of the instructions
+
+### When this workaround can be removed
+
+This approach compensates for Codex's plugin system not yet supporting an `agents`
+field in `plugin.json`. When `RawPluginManifest` gains an `agents` field, the
+plugin can symlink to `agents/` (mirroring the existing `skills/` symlink) and
+skills can dispatch named agent types directly.
+
+## Environment Detection
+
+Skills that create worktrees or finish branches should detect their
+environment with read-only git commands before proceeding:
+
+```bash
+GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
+GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
+BRANCH=$(git branch --show-current)
+```
+
+- `GIT_DIR != GIT_COMMON` → already in a linked worktree (skip creation)
+- `BRANCH` empty → detached HEAD (cannot branch/push/PR from sandbox)
+
+See `using-git-worktrees` Step 0 and `finishing-a-development-branch`
+Step 1 for how each skill uses these signals.
+
+## Codex App Finishing
+
+When the sandbox blocks branch/push operations (detached HEAD in an
+externally managed worktree), the agent commits all work and informs
+the user to use the App's native controls:
+
+- **"Create branch"** — names the branch, then commit/push/PR via App UI
+- **"Hand off to local"** — transfers work to the user's local checkout
+
+The agent can still run tests, stage files, and output suggested branch
+names, commit messages, and PR descriptions for the user to copy.

+Skills use Claude Code tool names. When you encounter these in a skill, use your platform equivalent:
+
+| Skill references | Copilot CLI equivalent |
+|-----------------|----------------------|
+| `Read` (file reading) | `view` |
+| `Write` (file creation) | `create` |

+
+Copilot CLI supports persistent async shell sessions, which have no direct Claude Code equivalent:
+
+| Tool | Purpose |
+|------|---------|
+| `bash` with `async: true` | Start a long-running command in the background |
+| `write_bash` | Send input to a running async session |
+| `read_bash` | Read output from an async session |
+| `stop_bash` | Terminate an async session |
+| `list_bash` | List all active shell sessions |
+
+## Additional Copilot CLI tools
+
+| Tool | Purpose |
+|------|---------|
+| `store_memory` | Persist facts about the codebase for future sessions |
+| `report_intent` | Update the UI status line with current intent |
+| `sql` | Query the session's SQLite database (todos, metadata) |
+| `fetch_copilot_cli_documentation` | Look up Copilot CLI documentation |

+| Skill references | Gemini CLI equivalent |
+|-----------------|----------------------|
+| `Read` (file reading) | `read_file` |
+| `Write` (file creation) | `write_file` |
+| `Edit` (file editing) | `replace` |
+| `Bash` (run commands) | `run_shell_command` |
+| `Grep` (search file content) | `grep_search` |
+| `Glob` (search files by name) | `glob` |
+| `TodoWrite` (task tracking) | `write_todos` |
+| `Skill` tool (invoke a skill) | `activate_skill` |
+| `WebSearch` | `google_web_search` |
+| `WebFetch` | `web_fetch` |
+| `Task` tool (dispatch subagent) | No equivalent — Gemini CLI does not support subagents |
+
+## No subagent support
+
+Gemini CLI has no equivalent to Claude Code's `Task` tool. Skills that rely on subagent dispatch (`subagent-driven-development`, `dispatching-parallel-agents`) will fall back to single-session execution via `executing-plans`.
+
+## Additional Gemini CLI tools
+
+These tools are available in Gemini CLI but have no Claude Code equivalent:
+
+| Tool | Purpose |
+|------|---------|
+| `list_directory` | List files and subdirectories |
+| `save_memory` | Persist facts to GEMINI.md across sessions |
+| `ask_user` | Request structured input from the user |
+| `tracker_create_task` | Rich task management (create, update, list, visualize) |
+| `enter_plan_mode` / `exit_plan_mode` | Switch to read-only research mode before making changes |

+name: verification-before-completion
+description: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always
+---
+
+# Verification Before Completion
+
+## Overview
+
+Claiming work is complete without verification is dishonesty, not efficiency.
+
+**Core principle:** Evidence before claims, always.
+
+**Violating the letter of this rule is violating the spirit of this rule.**
+
+## The Iron Law
+
+```
+NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE
+```
+
+If you haven't run the verification command in this message, you cannot claim it passes.
+
+## The Gate Function
+
+```
+BEFORE claiming any status or expressing satisfaction:
+
+1. IDENTIFY: What command proves this claim?
+2. RUN: Execute the FULL command (fresh, complete)
+3. READ: Full output, check exit code, count failures
+4. VERIFY: Does output confirm the claim?
+   - If NO: State actual status with evidence
+   - If YES: State claim WITH evidence
+5. ONLY THEN: Make the claim
+
+Skip any step = lying, not verifying
+```
+
+## Common Failures
+
+| Claim | Requires | Not Sufficient |
+|-------|----------|----------------|
+| Tests pass | Test command output: 0 failures | Previous run, "should pass" |
+| Linter clean | Linter output: 0 errors | Partial check, extrapolation |
+| Build succeeds | Build command: exit 0 | Linter passing, logs look good |
+| Bug fixed | Test original symptom: passes | Code changed, assumed fixed |
+| Regression test works | Red-green cycle verified | Test passes once |
+| Agent completed | VCS diff shows changes | Agent reports "success" |
+| Requirements met | Line-by-line checklist | Tests passing |
+
+## Red Flags - STOP
+
+- Using "should", "probably", "seems to"
+- Expressing satisfaction before verification ("Great!", "Perfect!", "Done!", etc.)
+- About to commit/push/PR without verification
+- Trusting agent success reports
+- Relying on partial verification
+- Thinking "just this once"
+- Tired and wanting work over
+- **ANY wording implying success without having run verification**
+
+## Rationalization Prevention
+
+| Excuse | Reality |
+|--------|---------|
+| "Should work now" | RUN the verification |
+| "I'm confident" | Confidence ≠ evidence |
+| "Just this once" | No exceptions |
+| "Linter passed" | Linter ≠ compiler |
+| "Agent said success" | Verify independently |
+| "I'm tired" | Exhaustion ≠ excuse |
+| "Partial check is enough" | Partial proves nothing |
+| "Different words so rule doesn't apply" | Spirit over letter |
+
+## Key Patterns
+
+**Tests:**
+```
+✅ [Run test command] [See: 34/34 pass] "All tests pass"
+❌ "Should pass now" / "Looks correct"
+```
+
+**Regression tests (TDD Red-Green):**
+```
+✅ Write → Run (pass) → Revert fix → Run (MUST FAIL) → Restore → Run (pass)
+❌ "I've written a regression test" (without red-green verification)
+```
+
+**Build:**
+```
+✅ [Run build] [See: exit 0] "Build passes"
+❌ "Linter passed" (linter doesn't check compilation)
+```
+
+**Requirements:**
+```
+✅ Re-read plan → Create checklist → Verify each → Report gaps or completion
+❌ "Tests pass, phase complete"
+```
+
+**Agent delegation:**
+```
+✅ Agent reports success → Check VCS diff → Verify changes → Report actual state
+❌ Trust agent report
+```
+
+## Why This Matters
+
+From 24 failure memories:
+- your human partner said "I don't believe you" - trust broken
+- Undefined functions shipped - would crash
+- Missing requirements shipped - incomplete features
+- Time wasted on false completion → redirect → rework
+- Violates: "Honesty is a core value. If you lie, you'll be replaced."
+
+## When To Apply
+
+**ALWAYS before:**
+- ANY variation of success/completion claims
+- ANY expression of satisfaction
+- ANY positive statement about work state
+- Committing, PR creation, task completion
+- Moving to next task
+- Delegating to agents
+
+**Rule applies to:**
+- Exact phrases
+- Paraphrases and synonyms
+- Implications of success
+- ANY communication suggesting completion/correctness
+
+## The Bottom Line
+
+**No shortcuts for verification.**
+
+Run the command. Read the output. THEN claim the result.
+
+This is non-negotiable.

+description: Use when you have a spec or requirements for a multi-step task, before touching code
+---
+
+# Writing Plans
+
+## Overview
+
+Write comprehensive implementation plans assuming the engineer has zero context for our codebase and questionable taste. Document everything they need to know: which files to touch for each task, code, testing, docs they might need to check, how to test it. Give them the whole plan as bite-sized tasks. DRY. YAGNI. TDD. Frequent commits.
+
+Assume they are a skilled developer, but know almost nothing about our toolset or problem domain. Assume they don't know good test design very well.
+
+**Announce at start:** "I'm using the writing-plans skill to create the implementation plan."
+
+**Context:** This should be run in a dedicated worktree (created by brainstorming skill).
+
+**Save plans to:** `.ai/plans/YYYY-MM-DD-<feature-name>.md`
+- (User preferences for plan location override this default)
+
+## Scope Check
+
+If the spec covers multiple independent subsystems, it should have been broken into sub-project specs during brainstorming. If it wasn't, suggest breaking this into separate plans — one per subsystem. Each plan should produce working, testable software on its own.
+
+## File Structure
+
+Before defining tasks, map out which files will be created or modified and what each one is responsible for. This is where decomposition decisions get locked in.
+
+- Design units with clear boundaries and well-defined interfaces. Each file should have one clear responsibility.
+- You reason best about code you can hold in context at once, and your edits are more reliable when files are focused. Prefer smaller, focused files over large ones that do too much.
+- Files that change together should live together. Split by responsibility, not by technical layer.
+- In existing codebases, follow established patterns. If the codebase uses large files, don't unilaterally restructure - but if a file you're modifying has grown unwieldy, including a split in the plan is reasonable.
+
+This structure informs the task decomposition. Each task should produce self-contained changes that make sense independently.
+
+## Bite-Sized Task Granularity
+
+**Each step is one action (2-5 minutes):**
+- "Write the failing test" - step
+- "Run it to make sure it fails" - step
+- "Implement the minimal code to make the test pass" - step
+- "Run the tests and make sure they pass" - step
+- "Commit" - step
+
+## Plan Document Header
+
+**Every plan MUST start with this header:**
+
+```markdown
+# [Feature Name] Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** [One sentence describing what this builds]
+
+**Architecture:** [2-3 sentences about approach]
+
+**Tech Stack:** [Key technologies/libraries]
+
+---
+```
+
+## Task Structure
+
+````markdown
+### Task N: [Component Name]
+
+**Files:**
+- Create: `exact/path/to/file.py`
+- Modify: `exact/path/to/existing.py:123-145`
+- Test: `tests/exact/path/to/test.py`
+
+- [ ] **Step 1: Write the failing test**
+
+```python
+def test_specific_behavior():
+    result = function(input)
+    assert result == expected
+```
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `pytest tests/path/test.py::test_name -v`
+Expected: FAIL with "function not defined"
+
+- [ ] **Step 3: Write minimal implementation**
+
+```python
+def function(input):
+    return expected
+```
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `pytest tests/path/test.py::test_name -v`
+Expected: PASS
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add tests/path/test.py src/path/file.py
+git commit -m "feat: add specific feature"
+```
+````
+
+## No Placeholders
+
+Every step must contain the actual content an engineer needs. These are **plan failures** — never write them:
+- "TBD", "TODO", "implement later", "fill in details"
+- "Add appropriate error handling" / "add validation" / "handle edge cases"
+- "Write tests for the above" (without actual test code)
+- "Similar to Task N" (repeat the code — the engineer may be reading tasks out of order)
+- Steps that describe what to do without showing how (code blocks required for code steps)
+- References to types, functions, or methods not defined in any task
+
+## Remember
+- Exact file paths always
+- Complete code in every step — if a step changes code, show the code
+- Exact commands with expected output
+- DRY, YAGNI, TDD, frequent commits
+
+## Self-Review
+
+After writing the complete plan, look at the spec with fresh eyes and check the plan against it. This is a checklist you run yourself — not a subagent dispatch.
+
+**1. Spec coverage:** Skim each section/requirement in the spec. Can you point to a task that implements it? List any gaps.
+
+**2. Placeholder scan:** Search your plan for red flags — any of the patterns from the "No Placeholders" section above. Fix them.
+
+**3. Type consistency:** Do the types, method signatures, and property names you used in later tasks match what you defined in earlier tasks? A function called `clearLayers()` in Task 3 but `clearFullLayers()` in Task 7 is a bug.
+
+If you find issues, fix them inline. No need to re-review — just fix and move on. If you find a spec requirement with no task, add the task.
+
+## Execution Handoff
+
+After saving the plan, offer execution choice:
+
+**"Plan complete and saved to `.ai/plans/<filename>.md`. Two execution options:**
+
+**1. Subagent-Driven (recommended)** - I dispatch a fresh subagent per task, review between tasks, fast iteration
+
+**2. Inline Execution** - Execute tasks in this session using executing-plans, batch execution with checkpoints
+
+**Which approach?"**
+
+**If Subagent-Driven chosen:**
+- **REQUIRED SUB-SKILL:** Use superpowers:subagent-driven-development
+- Fresh subagent per task + two-stage review
+
+**If Inline Execution chosen:**
+- **REQUIRED SUB-SKILL:** Use superpowers:executing-plans
+- Batch execution with checkpoints for review

+# Plan Document Reviewer Prompt Template
+
+Use this template when dispatching a plan document reviewer subagent.
+
+**Purpose:** Verify the plan is complete, matches the spec, and has proper task decomposition.
+
+**Dispatch after:** The complete plan is written.
+
+```
+Task tool (general-purpose):
+  description: "Review plan document"
+  prompt: |
+    You are a plan document reviewer. Verify this plan is complete and ready for implementation.
+
+    **Plan to review:** [PLAN_FILE_PATH]
+    **Spec for reference:** [SPEC_FILE_PATH]
+
+    ## What to Check
+
+    | Category | What to Look For |
+    |----------|------------------|
+    | Completeness | TODOs, placeholders, incomplete tasks, missing steps |
+    | Spec Alignment | Plan covers spec requirements, no major scope creep |
+    | Task Decomposition | Tasks have clear boundaries, steps are actionable |
+    | Buildability | Could an engineer follow this plan without getting stuck? |
+
+    ## Calibration
+
+    **Only flag issues that would cause real problems during implementation.**
+    An implementer building the wrong thing or getting stuck is an issue.
+    Minor wording, stylistic preferences, and "nice to have" suggestions are not.
+
+    Approve unless there are serious gaps — missing requirements from the spec,
+    contradictory steps, placeholder content, or tasks so vague they can't be acted on.
+
+    ## Output Format
+
+    ## Plan Review
+
+    **Status:** Approved | Issues Found
+
+    **Issues (if any):**
+    - [Task X, Step Y]: [specific issue] - [why it matters for implementation]
+
+    **Recommendations (advisory, do not block approval):**
+    - [suggestions for improvement]
+```

+
+# Writing Skills
+
+## Overview
+
+**Writing skills IS Test-Driven Development applied to process documentation.**
+
+**Personal skills live in agent-specific directories (`~/.claude/skills` for Claude Code, `~/.agents/skills/` for Codex)** 
+
+You write test cases (pressure scenarios with subagents), watch them fail (baseline behavior), write the skill (documentation), watch tests pass (agents comply), and refactor (close loopholes).
+
+**Core principle:** If you didn't watch an agent fail without the skill, you don't know if the skill teaches the right thing.
+
+**REQUIRED BACKGROUND:** You MUST understand superpowers:test-driven-development before using this skill. That skill defines the fundamental RED-GREEN-REFACTOR cycle. This skill adapts TDD to documentation.
+
+**Official guidance:** For Anthropic's official skill authoring best practices, see anthropic-best-practices.md. This document provides additional patterns and guidelines that complement the TDD-focused approach in this skill.
+
+## What is a Skill?
+
+A **skill** is a reference guide for proven techniques, patterns, or tools. Skills help future Claude instances find and apply effective approaches.
+
+**Skills are:** Reusable techniques, patterns, tools, reference guides
+
+**Skills are NOT:** Narratives about how you solved a problem once
+
+## TDD Mapping for Skills
+
+| TDD Concept | Skill Creation |
+|-------------|----------------|
+| **Test case** | Pressure scenario with subagent |
+| **Production code** | Skill document (SKILL.md) |
+| **Test fails (RED)** | Agent violates rule without skill (baseline) |
+| **Test passes (GREEN)** | Agent complies with skill present |
+| **Refactor** | Close loopholes while maintaining compliance |
+| **Write test first** | Run baseline scenario BEFORE writing skill |
+| **Watch it fail** | Document exact rationalizations agent uses |
+| **Minimal code** | Write skill addressing those specific violations |
+| **Watch it pass** | Verify agent now complies |
+| **Refactor cycle** | Find new rationalizations → plug → re-verify |
+
+The entire skill creation process follows RED-GREEN-REFACTOR.
+
+## When to Create a Skill
+
+**Create when:**
+- Technique wasn't intuitively obvious to you
+- You'd reference this again across projects
+- Pattern applies broadly (not project-specific)
+- Others would benefit
+
+**Don't create for:**
+- One-off solutions
+- Standard practices well-documented elsewhere
+- Project-specific conventions (put in CLAUDE.md)
+- Mechanical constraints (if it's enforceable with regex/validation, automate it—save documentation for judgment calls)
+
+## Skill Types
+
+### Technique
+Concrete method with steps to follow (condition-based-waiting, root-cause-tracing)
+
+### Pattern
+Way of thinking about problems (flatten-with-flags, test-invariants)
+
+### Reference
+API docs, syntax guides, tool documentation (office docs)
+
+## Directory Structure
+
+
+```
+skills/
+  skill-name/
+    SKILL.md              # Main reference (required)
+    supporting-file.*     # Only if needed
+```
+
+**Flat namespace** - all skills in one searchable namespace
+
+**Separate files for:**
+1. **Heavy reference** (100+ lines) - API docs, comprehensive syntax
+2. **Reusable tools** - Scripts, utilities, templates
+
+**Keep inline:**
+- Principles and concepts
+- Code patterns (< 50 lines)
+- Everything else
+
+## SKILL.md Structure
+
+**Frontmatter (YAML):**
+- Two required fields: `name` and `description` (see [agentskills.io/specification](https://agentskills.io/specification) for all supported fields)
+- Max 1024 characters total
+- `name`: Use letters, numbers, and hyphens only (no parentheses, special chars)
+- `description`: Third-person, describes ONLY when to use (NOT what it does)
+  - Start with "Use when..." to focus on triggering conditions
+  - Include specific symptoms, situations, and contexts
+  - **NEVER summarize the skill's process or workflow** (see CSO section for why)
+  - Keep under 500 characters if possible
+
+```markdown
+---
+name: Skill-Name-With-Hyphens

+## Real-World Impact (optional)
+Concrete results
+```
+
+
+## Claude Search Optimization (CSO)
+
+**Critical for discovery:** Future Claude needs to FIND your skill
+
+### 1. Rich Description Field
+
+**Purpose:** Claude reads description to decide which skills to load for a given task. Make it answer: "Should I read this skill right now?"
+
+**Format:** Start with "Use when..." to focus on triggering conditions
+
+**CRITICAL: Description = When to Use, NOT What the Skill Does**
+
+The description should ONLY describe triggering conditions. Do NOT summarize the skill's process or workflow in the description.
+
+**Why this matters:** Testing revealed that when a description summarizes the skill's workflow, Claude may follow the description instead of reading the full skill content. A description saying "code review between tasks" caused Claude to do ONE review, even though the skill's flowchart clearly showed TWO reviews (spec compliance then code quality).
+
+When the description was changed to just "Use when executing implementation plans with independent tasks" (no workflow summary), Claude correctly read the flowchart and followed the two-stage review process.
+
+**The trap:** Descriptions that summarize workflow create a shortcut Claude will take. The skill body becomes documentation Claude skips.
+
+```yaml
+# ❌ BAD: Summarizes workflow - Claude may follow this instead of reading skill
+description: Use when executing plans - dispatches subagent per task with code review between tasks
+
+# ❌ BAD: Too much process detail
+description: Use for TDD - write test first, watch it fail, write minimal code, refactor
+
+# ✅ GOOD: Just triggering conditions, no workflow summary
+description: Use when executing implementation plans with independent tasks in the current session
+
+# ✅ GOOD: Triggering conditions only
+description: Use when implementing any feature or bugfix, before writing implementation code
+```
+
+**Content:**
+- Use concrete triggers, symptoms, and situations that signal this skill applies
+- Describe the *problem* (race conditions, inconsistent behavior) not *language-specific symptoms* (setTimeout, sleep)
+- Keep triggers technology-agnostic unless the skill itself is technology-specific
+- If skill is technology-specific, make that explicit in the trigger
+- Write in third person (injected into system prompt)
+- **NEVER summarize the skill's process or workflow**
+
+```yaml
+# ❌ BAD: Too abstract, vague, doesn't include when to use
+description: For async testing
+
+# ❌ BAD: First person
+description: I can help you with async tests when they're flaky
+
+# ❌ BAD: Mentions technology but skill isn't specific to it
+description: Use when tests use setTimeout/sleep and are flaky
+
+# ✅ GOOD: Starts with "Use when", describes problem, no workflow
+description: Use when tests have race conditions, timing dependencies, or pass/fail inconsistently
+
+# ✅ GOOD: Technology-specific skill with explicit trigger
+description: Use when using React Router and handling authentication redirects
+```
+
+### 2. Keyword Coverage
+
+Use words Claude would search for:
+- Error messages: "Hook timed out", "ENOTEMPTY", "race condition"
+- Symptoms: "flaky", "hanging", "zombie", "pollution"
+- Synonyms: "timeout/hang/freeze", "cleanup/teardown/afterEach"
+- Tools: Actual commands, library names, file types
+
+### 3. Descriptive Naming
+
+**Use active voice, verb-first:**
+- ✅ `creating-skills` not `skill-creation`
+- ✅ `condition-based-waiting` not `async-test-helpers`
+
+### 4. Token Efficiency (Critical)
+
+**Problem:** getting-started and frequently-referenced skills load into EVERY conversation. Every token counts.
+
+**Target word counts:**
+- getting-started workflows: <150 words each
+- Frequently-loaded skills: <200 words total
+- Other skills: <500 words (still be concise)
+
+**Techniques:**
+
+**Move details to tool help:**
+```bash
+# ❌ BAD: Document all flags in SKILL.md
+search-conversations supports --text, --both, --after DATE, --before DATE, --limit N
+
+# ✅ GOOD: Reference --help
+search-conversations supports multiple modes and filters. Run --help for details.
+```
+
+**Use cross-references:**
+```markdown
+# ❌ BAD: Repeat workflow details
+When searching, dispatch subagent with template...
+[20 lines of repeated instructions]
+
+# ✅ GOOD: Reference other skill
+Always use subagents (50-100x context savings). REQUIRED: Use [other-skill-name] for workflow.
+```
+
+**Compress examples:**
+```markdown
+# ❌ BAD: Verbose example (42 words)
+your human partner: "How did we handle authentication errors in React Router before?"
+You: I'll search past conversations for React Router authentication patterns.
+[Dispatch subagent with search query: "React Router authentication error handling 401"]
+
+# ✅ GOOD: Minimal example (20 words)
+Partner: "How did we handle auth errors in React Router?"
+You: Searching...
+[Dispatch subagent → synthesis]
+```
+
+**Eliminate redundancy:**
+- Don't repeat what's in cross-referenced skills
+- Don't explain what's obvious from command
+- Don't include multiple examples of same pattern
+
+**Verification:**
+```bash
+wc -w skills/path/SKILL.md
+# getting-started workflows: aim for <150 each
+# Other frequently-loaded: aim for <200 total
+```
+
+**Name by what you DO or core insight:**
+- ✅ `condition-based-waiting` > `async-test-helpers`
+- ✅ `using-skills` not `skill-usage`
+- ✅ `flatten-with-flags` > `data-structure-refactoring`
+- ✅ `root-cause-tracing` > `debugging-techniques`
+
+**Gerunds (-ing) work well for processes:**
+- `creating-skills`, `testing-skills`, `debugging-with-logs`
+- Active, describes the action you're taking
+
+### 4. Cross-Referencing Other Skills
+
+**When writing documentation that references other skills:**
+
+Use skill name only, with explicit requirement markers:
+- ✅ Good: `**REQUIRED SUB-SKILL:** Use superpowers:test-driven-development`
+- ✅ Good: `**REQUIRED BACKGROUND:** You MUST understand superpowers:systematic-debugging`
+- ❌ Bad: `See skills/testing/test-driven-development` (unclear if required)
+- ❌ Bad: `@skills/testing/test-driven-development/SKILL.md` (force-loads, burns context)
+
+**Why no @ links:** `@` syntax force-loads files immediately, consuming 200k+ context before you need them.
+
+## Flowchart Usage
+
+```dot
+digraph when_flowchart {
+    "Need to show information?" [shape=diamond];
+    "Decision where I might go wrong?" [shape=diamond];
+    "Use markdown" [shape=box];
+    "Small inline flowchart" [shape=box];
+
+    "Need to show information?" -> "Decision where I might go wrong?" [label="yes"];
+    "Decision where I might go wrong?" -> "Small inline flowchart" [label="yes"];
+    "Decision where I might go wrong?" -> "Use markdown" [label="no"];
+}
+```
+
+**Use flowcharts ONLY for:**
+- Non-obvious decision points
+- Process loops where you might stop too early
+- "When to use A vs B" decisions
+
+**Never use flowcharts for:**
+- Reference material → Tables, lists
+- Code examples → Markdown blocks
+- Linear instructions → Numbered lists
+- Labels without semantic meaning (step1, helper2)
+
+See @graphviz-conventions.dot for graphviz style rules.
+
+**Visualizing for your human partner:** Use `render-graphs.js` in this directory to render a skill's flowcharts to SVG:
+```bash
+./render-graphs.js ../some-skill           # Each diagram separately
+./render-graphs.js ../some-skill --combine # All diagrams in one SVG
+```
+
+## Code Examples
+
+**One excellent example beats many mediocre ones**
+
+Choose most relevant language:
+- Testing techniques → TypeScript/JavaScript
+- System debugging → Shell/Python
+- Data processing → Python
+
+**Good example:**
+- Complete and runnable
+- Well-commented explaining WHY
+- From real scenario
+- Shows pattern clearly
+- Ready to adapt (not generic template)
+
+**Don't:**
+- Implement in 5+ languages
+- Create fill-in-the-blank templates
+- Write contrived examples
+
+You're good at porting - one great example is enough.
+
+## File Organization
+
+### Self-Contained Skill
+```
+defense-in-depth/
+  SKILL.md    # Everything inline
+```
+When: All content fits, no heavy reference needed
+
+### Skill with Reusable Tool
+```
+condition-based-waiting/
+  SKILL.md    # Overview + patterns
+  example.ts  # Working helpers to adapt
+```
+When: Tool is reusable code, not just narrative
+
+### Skill with Heavy Reference
+```
+pptx/
+  SKILL.md       # Overview + workflows
+  pptxgenjs.md   # 600 lines API reference
+  ooxml.md       # 500 lines XML structure
+  scripts/       # Executable tools
+```
+When: Reference material too large for inline
+
+## The Iron Law (Same as TDD)
+
+```
+NO SKILL WITHOUT A FAILING TEST FIRST
+```
+
+This applies to NEW skills AND EDITS to existing skills.
+
+Write skill before testing? Delete it. Start over.
+Edit skill without testing? Same violation.
+
+**No exceptions:**
+- Not for "simple additions"
+- Not for "just adding a section"
+- Not for "documentation updates"
+- Don't keep untested changes as "reference"
+- Don't "adapt" while running tests
+- Delete means delete
+
+**REQUIRED BACKGROUND:** The superpowers:test-driven-development skill explains why this matters. Same principles apply to documentation.
+
+## Testing All Skill Types
+
+Different skill types need different test approaches:
+
+### Discipline-Enforcing Skills (rules/requirements)
+
+**Examples:** TDD, verification-before-completion, designing-before-coding
+
+**Test with:**
+- Academic questions: Do they understand the rules?
+- Pressure scenarios: Do they comply under stress?
+- Multiple pressures combined: time + sunk cost + exhaustion
+- Identify rationalizations and add explicit counters
+
+**Success criteria:** Agent follows rule under maximum pressure
+
+### Technique Skills (how-to guides)
+
+**Examples:** condition-based-waiting, root-cause-tracing, defensive-programming
+
+**Test with:**
+- Application scenarios: Can they apply the technique correctly?
+- Variation scenarios: Do they handle edge cases?
+- Missing information tests: Do instructions have gaps?
+
+**Success criteria:** Agent successfully applies technique to new scenario
+
+### Pattern Skills (mental models)
+
+**Examples:** reducing-complexity, information-hiding concepts
+
+**Test with:**
+- Recognition scenarios: Do they recognize when pattern applies?
+- Application scenarios: Can they use the mental model?
+- Counter-examples: Do they know when NOT to apply?
+
+**Success criteria:** Agent correctly identifies when/how to apply pattern
+
+### Reference Skills (documentation/APIs)
+
+**Examples:** API documentation, command references, library guides
+
+**Test with:**
+- Retrieval scenarios: Can they find the right information?
+- Application scenarios: Can they use what they found correctly?
+- Gap testing: Are common use cases covered?
+
+**Success criteria:** Agent finds and correctly applies reference information
+
+## Common Rationalizations for Skipping Testing
+
+| Excuse | Reality |
+|--------|---------|
+| "Skill is obviously clear" | Clear to you ≠ clear to other agents. Test it. |
+| "It's just a reference" | References can have gaps, unclear sections. Test retrieval. |
+| "Testing is overkill" | Untested skills have issues. Always. 15 min testing saves hours. |
+| "I'll test if problems emerge" | Problems = agents can't use skill. Test BEFORE deploying. |
+| "Too tedious to test" | Testing is less tedious than debugging bad skill in production. |
+| "I'm confident it's good" | Overconfidence guarantees issues. Test anyway. |
+| "Academic review is enough" | Reading ≠ using. Test application scenarios. |
+| "No time to test" | Deploying untested skill wastes more time fixing it later. |
+
+**All of these mean: Test before deploying. No exceptions.**
+
+## Bulletproofing Skills Against Rationalization
+
+Skills that enforce discipline (like TDD) need to resist rationalization. Agents are smart and will find loopholes when under pressure.
+
+**Psychology note:** Understanding WHY persuasion techniques work helps you apply them systematically. See persuasion-principles.md for research foundation (Cialdini, 2021; Meincke et al., 2025) on authority, commitment, scarcity, social proof, and unity principles.
+
+### Close Every Loophole Explicitly
+
+Don't just state the rule - forbid specific workarounds:
+
+<Bad>
+```markdown
+Write code before test? Delete it.
+```
+</Bad>
+
+<Good>
+```markdown
+Write code before test? Delete it. Start over.
+
+**No exceptions:**
+- Don't keep it as "reference"
+- Don't "adapt" it while writing tests
+- Don't look at it
+- Delete means delete
+```
+</Good>
+
+### Address "Spirit vs Letter" Arguments
+
+Add foundational principle early:
+
+```markdown
+**Violating the letter of the rules is violating the spirit of the rules.**
+```
+
+This cuts off entire class of "I'm following the spirit" rationalizations.
+
+### Build Rationalization Table
+
+Capture rationalizations from baseline testing (see Testing section below). Every excuse agents make goes in the table:
+
+```markdown
+| Excuse | Reality |
+|--------|---------|
+| "Too simple to test" | Simple code breaks. Test takes 30 seconds. |
+| "I'll test after" | Tests passing immediately prove nothing. |
+| "Tests after achieve same goals" | Tests-after = "what does this do?" Tests-first = "what should this do?" |
+```
+
+### Create Red Flags List
+
+Make it easy for agents to self-check when rationalizing:
+
+```markdown
+## Red Flags - STOP and Start Over
+
+- Code before test
+- "I already manually tested it"
+- "Tests after achieve the same purpose"
+- "It's about spirit not ritual"
+- "This is different because..."
+
+**All of these mean: Delete code. Start over with TDD.**
+```
+
+### Update CSO for Violation Symptoms
+
+Add to description: symptoms of when you're ABOUT to violate the rule:
+
+```yaml
+description: use when implementing any feature or bugfix, before writing implementation code
+```
+
+## RED-GREEN-REFACTOR for Skills
+
+Follow the TDD cycle:
+
+### RED: Write Failing Test (Baseline)
+
+Run pressure scenario with subagent WITHOUT the skill. Document exact behavior:
+- What choices did they make?
+- What rationalizations did they use (verbatim)?
+- Which pressures triggered violations?
+
+This is "watch the test fail" - you must see what agents naturally do before writing the skill.
+
+### GREEN: Write Minimal Skill
+
+Write skill that addresses those specific rationalizations. Don't add extra content for hypothetical cases.
+
+Run same scenarios WITH skill. Agent should now comply.
+
+### REFACTOR: Close Loopholes
+
+Agent found new rationalization? Add explicit counter. Re-test until bulletproof.
+
+**Testing methodology:** See @testing-skills-with-subagents.md for the complete testing methodology:
+- How to write pressure scenarios
+- Pressure types (time, sunk cost, authority, exhaustion)
+- Plugging holes systematically
+- Meta-testing techniques
+
+## Anti-Patterns
+
+### ❌ Narrative Example
+"In session 2025-10-03, we found empty projectDir caused..."
+**Why bad:** Too specific, not reusable
+
+### ❌ Multi-Language Dilution
+example-js.js, example-py.py, example-go.go
+**Why bad:** Mediocre quality, maintenance burden
+
+### ❌ Code in Flowcharts
+```dot
+step1 [label="import fs"];
+step2 [label="read file"];
+```
+**Why bad:** Can't copy-paste, hard to read
+
+### ❌ Generic Labels
+helper1, helper2, step3, pattern4
+**Why bad:** Labels should have semantic meaning
+
+## STOP: Before Moving to Next Skill
+
+**After writing ANY skill, you MUST STOP and complete the deployment process.**
+
+**Do NOT:**
+- Create multiple skills in batch without testing each
+- Move to next skill before current one is verified
+- Skip testing because "batching is more efficient"
+
+**The deployment checklist below is MANDATORY for EACH skill.**
+
+Deploying untested skills = deploying untested code. It's a violation of quality standards.
+
+## Skill Creation Checklist (TDD Adapted)
+
+**IMPORTANT: Use TodoWrite to create todos for EACH checklist item below.**
+
+**RED Phase - Write Failing Test:**
+- [ ] Create pressure scenarios (3+ combined pressures for discipline skills)
+- [ ] Run scenarios WITHOUT skill - document baseline behavior verbatim
+- [ ] Identify patterns in rationalizations/failures
+
+**GREEN Phase - Write Minimal Skill:**
+- [ ] Name uses only letters, numbers, hyphens (no parentheses/special chars)
+- [ ] YAML frontmatter with required `name` and `description` fields (max 1024 chars; see [spec](https://agentskills.io/specification))
+- [ ] Description starts with "Use when..." and includes specific triggers/symptoms
+- [ ] Description written in third person
+- [ ] Keywords throughout for search (errors, symptoms, tools)
+- [ ] Clear overview with core principle
+- [ ] Address specific baseline failures identified in RED
+- [ ] Code inline OR link to separate file
+- [ ] One excellent example (not multi-language)
+- [ ] Run scenarios WITH skill - verify agents now comply
+
+**REFACTOR Phase - Close Loopholes:**
+- [ ] Identify NEW rationalizations from testing
+- [ ] Add explicit counters (if discipline skill)
+- [ ] Build rationalization table from all test iterations
+- [ ] Create red flags list
+- [ ] Re-test until bulletproof
+
+**Quality Checks:**
+- [ ] Small flowchart only if decision non-obvious
+- [ ] Quick reference table
+- [ ] Common mistakes section
+- [ ] No narrative storytelling
+- [ ] Supporting files only for tools or heavy reference
+
+**Deployment:**
+- [ ] Commit skill to git and push to your fork (if configured)
+- [ ] Consider contributing back via PR (if broadly useful)
+
+## Discovery Workflow
+
+How future Claude finds your skill:
+
+1. **Encounters problem** ("tests are flaky")
+3. **Finds SKILL** (description matches)
+4. **Scans overview** (is this relevant?)
+5. **Reads patterns** (quick reference table)
+6. **Loads example** (only when implementing)
+
+**Optimize for this flow** - put searchable terms early and often.
+
+## The Bottom Line
+
+**Creating skills IS TDD for process documentation.**
+
+Same Iron Law: No skill without failing test first.
+Same cycle: RED (baseline) → GREEN (write skill) → REFACTOR (close loopholes).
+Same benefits: Better quality, fewer surprises, bulletproof results.
+
+If you follow TDD for code, follow it for skills. It's the same discipline applied to documentation.

+# Skill authoring best practices
+
+> Learn how to write effective Skills that Claude can discover and use successfully.
+
+Good Skills are concise, well-structured, and tested with real usage. This guide provides practical authoring decisions to help you write Skills that Claude can discover and use effectively.
+
+For conceptual background on how Skills work, see the [Skills overview](/en/docs/agents-and-tools/agent-skills/overview).
+
+## Core principles
+
+### Concise is key
+
+The [context window](https://platform.claude.com/docs/en/build-with-claude/context-windows) is a public good. Your Skill shares the context window with everything else Claude needs to know, including:
+
+* The system prompt
+* Conversation history
+* Other Skills' metadata
+* Your actual request
+
+Not every token in your Skill has an immediate cost. At startup, only the metadata (name and description) from all Skills is pre-loaded. Claude reads SKILL.md only when the Skill becomes relevant, and reads additional files only as needed. However, being concise in SKILL.md still matters: once Claude loads it, every token competes with conversation history and other context.
+
+**Default assumption**: Claude is already very smart
+
+Only add context Claude doesn't already have. Challenge each piece of information:
+
+* "Does Claude really need this explanation?"
+* "Can I assume Claude knows this?"
+* "Does this paragraph justify its token cost?"
+
+**Good example: Concise** (approximately 50 tokens):
+
+````markdown  theme={null}
+## Extract PDF text
+
+Use pdfplumber for text extraction:
+
+```python
+import pdfplumber
+
+with pdfplumber.open("file.pdf") as pdf:
+    text = pdf.pages[0].extract_text()
+```
+````
+
+**Bad example: Too verbose** (approximately 150 tokens):
+
+```markdown  theme={null}
+## Extract PDF text
+
+PDF (Portable Document Format) files are a common file format that contains
+text, images, and other content. To extract text from a PDF, you'll need to
+use a library. There are many libraries available for PDF processing, but we
+recommend pdfplumber because it's easy to use and handles most cases well.
+First, you'll need to install it using pip. Then you can use the code below...
+```
+
+The concise version assumes Claude knows what PDFs are and how libraries work.
+
+### Set appropriate degrees of freedom
+
+Match the level of specificity to the task's fragility and variability.
+
+**High freedom** (text-based instructions):
+
+Use when:
+
+* Multiple approaches are valid
+* Decisions depend on context
+* Heuristics guide the approach
+
+Example:
+
+```markdown  theme={null}
+## Code review process
+
+1. Analyze the code structure and organization
+2. Check for potential bugs or edge cases
+3. Suggest improvements for readability and maintainability
+4. Verify adherence to project conventions
+```
+
+**Medium freedom** (pseudocode or scripts with parameters):
+
+Use when:
+
+* A preferred pattern exists
+* Some variation is acceptable
+* Configuration affects behavior
+
+Example:
+
+````markdown  theme={null}
+## Generate report
+
+Use this template and customize as needed:
+
+```python
+def generate_report(data, format="markdown", include_charts=True):
+    # Process data
+    # Generate output in specified format
+    # Optionally include visualizations
+```
+````
+
+**Low freedom** (specific scripts, few or no parameters):
+
+Use when:
+
+* Operations are fragile and error-prone
+* Consistency is critical
+* A specific sequence must be followed
+
+Example:
+
+````markdown  theme={null}
+## Database migration
+
+Run exactly this script:
+
+```bash
+python scripts/migrate.py --verify --backup
+```
+
+Do not modify the command or add additional flags.
+````
+
+**Analogy**: Think of Claude as a robot exploring a path:
+
+* **Narrow bridge with cliffs on both sides**: There's only one safe way forward. Provide specific guardrails and exact instructions (low freedom). Example: database migrations that must run in exact sequence.
+* **Open field with no hazards**: Many paths lead to success. Give general direction and trust Claude to find the best route (high freedom). Example: code reviews where context determines the best approach.
+
+### Test with all models you plan to use
+
+Skills act as additions to models, so effectiveness depends on the underlying model. Test your Skill with all the models you plan to use it with.
+
+**Testing considerations by model**:
+
+* **Claude Haiku** (fast, economical): Does the Skill provide enough guidance?
+* **Claude Sonnet** (balanced): Is the Skill clear and efficient?
+* **Claude Opus** (powerful reasoning): Does the Skill avoid over-explaining?
+
+What works perfectly for Opus might need more detail for Haiku. If you plan to use your Skill across multiple models, aim for instructions that work well with all of them.
+
+## Skill structure
+
+<Note>
+  **YAML Frontmatter**: The SKILL.md frontmatter requires two fields:
+
+  * `name` - Human-readable name of the Skill (64 characters maximum)
+  * `description` - One-line description of what the Skill does and when to use it (1024 characters maximum)
+
+  For complete Skill structure details, see the [Skills overview](/en/docs/agents-and-tools/agent-skills/overview#skill-structure).
+</Note>
+
+### Naming conventions
+
+Use consistent naming patterns to make Skills easier to reference and discuss. We recommend using **gerund form** (verb + -ing) for Skill names, as this clearly describes the activity or capability the Skill provides.
+
+**Good naming examples (gerund form)**:
+
+* "Processing PDFs"
+* "Analyzing spreadsheets"
+* "Managing databases"
+* "Testing code"
+* "Writing documentation"
+
+**Acceptable alternatives**:
+
+* Noun phrases: "PDF Processing", "Spreadsheet Analysis"
+* Action-oriented: "Process PDFs", "Analyze Spreadsheets"
+
+**Avoid**:
+
+* Vague names: "Helper", "Utils", "Tools"
+* Overly generic: "Documents", "Data", "Files"
+* Inconsistent patterns within your skill collection
+
+Consistent naming makes it easier to:
+
+* Reference Skills in documentation and conversations
+* Understand what a Skill does at a glance
+* Organize and search through multiple Skills
+* Maintain a professional, cohesive skill library
+
+### Writing effective descriptions
+
+The `description` field enables Skill discovery and should include both what the Skill does and when to use it.
+
+<Warning>
+  **Always write in third person**. The description is injected into the system prompt, and inconsistent point-of-view can cause discovery problems.
+
+  * **Good:** "Processes Excel files and generates reports"
+  * **Avoid:** "I can help you process Excel files"
+  * **Avoid:** "You can use this to process Excel files"
+</Warning>
+
+**Be specific and include key terms**. Include both what the Skill does and specific triggers/contexts for when to use it.
+
+Each Skill has exactly one description field. The description is critical for skill selection: Claude uses it to choose the right Skill from potentially 100+ available Skills. Your description must provide enough detail for Claude to know when to select this Skill, while the rest of SKILL.md provides the implementation details.
+
+Effective examples:
+
+**PDF Processing skill:**
+
+```yaml  theme={null}
+description: Extract text and tables from PDF files, fill forms, merge documents. Use when working with PDF files or when the user mentions PDFs, forms, or document extraction.
+```
+
+**Excel Analysis skill:**
+
+```yaml  theme={null}
+description: Analyze Excel spreadsheets, create pivot tables, generate charts. Use when analyzing Excel files, spreadsheets, tabular data, or .xlsx files.
+```
+
+**Git Commit Helper skill:**
+
+```yaml  theme={null}
+description: Generate descriptive commit messages by analyzing git diffs. Use when the user asks for help writing commit messages or reviewing staged changes.
+```
+
+Avoid vague descriptions like these:
+
+```yaml  theme={null}
+description: Helps with documents
+```
+
+```yaml  theme={null}
+description: Processes data
+```
+
+```yaml  theme={null}
+description: Does stuff with files
+```
+
+### Progressive disclosure patterns
+
+SKILL.md serves as an overview that points Claude to detailed materials as needed, like a table of contents in an onboarding guide. For an explanation of how progressive disclosure works, see [How Skills work](/en/docs/agents-and-tools/agent-skills/overview#how-skills-work) in the overview.
+
+**Practical guidance:**
+
+* Keep SKILL.md body under 500 lines for optimal performance
+* Split content into separate files when approaching this limit
+* Use the patterns below to organize instructions, code, and resources effectively
+
+#### Visual overview: From simple to complex
+
+A basic Skill starts with just a SKILL.md file containing metadata and instructions:
+
+<img src="https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-simple-file.png?fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=87782ff239b297d9a9e8e1b72ed72db9" alt="Simple SKILL.md file showing YAML frontmatter and markdown body" data-og-width="2048" width="2048" data-og-height="1153" height="1153" data-path="images/agent-skills-simple-file.png" data-optimize="true" data-opv="3" srcset="https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-simple-file.png?w=280&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=c61cc33b6f5855809907f7fda94cd80e 280w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-simple-file.png?w=560&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=90d2c0c1c76b36e8d485f49e0810dbfd 560w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-simple-file.png?w=840&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=ad17d231ac7b0bea7e5b4d58fb4aeabb 840w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-simple-file.png?w=1100&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=f5d0a7a3c668435bb0aee9a3a8f8c329 1100w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-simple-file.png?w=1650&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=0e927c1af9de5799cfe557d12249f6e6 1650w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-simple-file.png?w=2500&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=46bbb1a51dd4c8202a470ac8c80a893d 2500w" />
+
+As your Skill grows, you can bundle additional content that Claude loads only when needed:
+
+<img src="https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-bundling-content.png?fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=a5e0aa41e3d53985a7e3e43668a33ea3" alt="Bundling additional reference files like reference.md and forms.md." data-og-width="2048" width="2048" data-og-height="1327" height="1327" data-path="images/agent-skills-bundling-content.png" data-optimize="true" data-opv="3" srcset="https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-bundling-content.png?w=280&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=f8a0e73783e99b4a643d79eac86b70a2 280w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-bundling-content.png?w=560&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=dc510a2a9d3f14359416b706f067904a 560w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-bundling-content.png?w=840&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=82cd6286c966303f7dd914c28170e385 840w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-bundling-content.png?w=1100&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=56f3be36c77e4fe4b523df209a6824c6 1100w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-bundling-content.png?w=1650&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=d22b5161b2075656417d56f41a74f3dd 1650w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-bundling-content.png?w=2500&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=3dd4bdd6850ffcc96c6c45fcb0acd6eb 2500w" />
+
+The complete Skill directory structure might look like this:
+
+```
+pdf/
+├── SKILL.md              # Main instructions (loaded when triggered)
+├── FORMS.md              # Form-filling guide (loaded as needed)
+├── reference.md          # API reference (loaded as needed)
+├── examples.md           # Usage examples (loaded as needed)
+└── scripts/
+    ├── analyze_form.py   # Utility script (executed, not loaded)
+    ├── fill_form.py      # Form filling script
+    └── validate.py       # Validation script
+```
+
+#### Pattern 1: High-level guide with references
+
+````markdown  theme={null}
+---
+name: PDF Processing
+description: Extracts text and tables from PDF files, fills forms, and merges documents. Use when working with PDF files or when the user mentions PDFs, forms, or document extraction.
+---
+
+# PDF Processing
+
+## Quick start
+
+Extract text with pdfplumber:
+```python
+import pdfplumber
+with pdfplumber.open("file.pdf") as pdf:
+    text = pdf.pages[0].extract_text()
+```
+
+## Advanced features
+
+**Form filling**: See [FORMS.md](FORMS.md) for complete guide
+**API reference**: See [REFERENCE.md](REFERENCE.md) for all methods
+**Examples**: See [EXAMPLES.md](EXAMPLES.md) for common patterns
+````
+
+Claude loads FORMS.md, REFERENCE.md, or EXAMPLES.md only when needed.
+
+#### Pattern 2: Domain-specific organization
+
+For Skills with multiple domains, organize content by domain to avoid loading irrelevant context. When a user asks about sales metrics, Claude only needs to read sales-related schemas, not finance or marketing data. This keeps token usage low and context focused.

+````
+
+#### Pattern 3: Conditional details
+
+Show basic content, link to advanced content:
+
+```markdown  theme={null}
+# DOCX Processing
+
+## Creating documents
+
+Use docx-js for new documents. See [DOCX-JS.md](DOCX-JS.md).
+
+## Editing documents
+
+For simple edits, modify the XML directly.
+
+**For tracked changes**: See [REDLINING.md](REDLINING.md)
+**For OOXML details**: See [OOXML.md](OOXML.md)
+```
+
+Claude reads REDLINING.md or OOXML.md only when the user needs those features.
+
+### Avoid deeply nested references
+
+Claude may partially read files when they're referenced from other referenced files. When encountering nested references, Claude might use commands like `head -100` to preview content rather than reading entire files, resulting in incomplete information.
+
+**Keep references one level deep from SKILL.md**. All reference files should link directly from SKILL.md to ensure Claude reads complete files when needed.
+
+**Bad example: Too deep**:
+
+```markdown  theme={null}
+# SKILL.md
+See [advanced.md](advanced.md)...
+
+# advanced.md
+See [details.md](details.md)...
+
+# details.md
+Here's the actual information...
+```
+
+**Good example: One level deep**:
+
+```markdown  theme={null}
+# SKILL.md
+
+**Basic usage**: [instructions in SKILL.md]
+**Advanced features**: See [advanced.md](advanced.md)
+**API reference**: See [reference.md](reference.md)
+**Examples**: See [examples.md](examples.md)
+```
+
+### Structure longer reference files with table of contents
+
+For reference files longer than 100 lines, include a table of contents at the top. This ensures Claude can see the full scope of available information even when previewing with partial reads.
+
+**Example**:
+
+```markdown  theme={null}
+# API Reference
+
+## Contents
+- Authentication and setup
+- Core methods (create, read, update, delete)
+- Advanced features (batch operations, webhooks)
+- Error handling patterns
+- Code examples
+
+## Authentication and setup
+...
+
+## Core methods
+...
+```
+
+Claude can then read the complete file or jump to specific sections as needed.
+
+For details on how this filesystem-based architecture enables progressive disclosure, see the [Runtime environment](#runtime-environment) section in the Advanced section below.
+
+## Workflows and feedback loops
+
+### Use workflows for complex tasks
+
+Break complex operations into clear, sequential steps. For particularly complex workflows, provide a checklist that Claude can copy into its response and check off as it progresses.
+
+**Example 1: Research synthesis workflow** (for Skills without code):
+
+````markdown  theme={null}
+## Research synthesis workflow
+
+Copy this checklist and track your progress:
+
+```
+Research Progress:
+- [ ] Step 1: Read all source documents
+- [ ] Step 2: Identify key themes
+- [ ] Step 3: Cross-reference claims
+- [ ] Step 4: Create structured summary
+- [ ] Step 5: Verify citations
+```
+
+**Step 1: Read all source documents**
+
+Review each document in the `sources/` directory. Note the main arguments and supporting evidence.
+
+**Step 2: Identify key themes**
+
+Look for patterns across sources. What themes appear repeatedly? Where do sources agree or disagree?
+
+**Step 3: Cross-reference claims**
+
+For each major claim, verify it appears in the source material. Note which source supports each point.
+
+**Step 4: Create structured summary**
+
+Organize findings by theme. Include:
+- Main claim
+- Supporting evidence from sources
+- Conflicting viewpoints (if any)
+
+**Step 5: Verify citations**
+
+Check that every claim references the correct source document. If citations are incomplete, return to Step 3.
+````
+
+This example shows how workflows apply to analysis tasks that don't require code. The checklist pattern works for any complex, multi-step process.
+
+**Example 2: PDF form filling workflow** (for Skills with code):
+
+````markdown  theme={null}
+## PDF form filling workflow
+
+Copy this checklist and check off items as you complete them:
+
+```
+Task Progress:
+- [ ] Step 1: Analyze the form (run analyze_form.py)
+- [ ] Step 2: Create field mapping (edit fields.json)
+- [ ] Step 3: Validate mapping (run validate_fields.py)
+- [ ] Step 4: Fill the form (run fill_form.py)
+- [ ] Step 5: Verify output (run verify_output.py)
+```
+
+**Step 1: Analyze the form**
+
+Run: `python scripts/analyze_form.py input.pdf`
+
+This extracts form fields and their locations, saving to `fields.json`.
+
+**Step 2: Create field mapping**
+
+Edit `fields.json` to add values for each field.
+
+**Step 3: Validate mapping**
+
+Run: `python scripts/validate_fields.py fields.json`
+
+Fix any validation errors before continuing.
+
+**Step 4: Fill the form**
+
+Run: `python scripts/fill_form.py input.pdf fields.json output.pdf`
+
+**Step 5: Verify output**
+
+Run: `python scripts/verify_output.py output.pdf`
+
+If verification fails, return to Step 2.
+````
+
+Clear steps prevent Claude from skipping critical validation. The checklist helps both Claude and you track progress through multi-step workflows.
+
+### Implement feedback loops
+
+**Common pattern**: Run validator → fix errors → repeat
+
+This pattern greatly improves output quality.
+
+**Example 1: Style guide compliance** (for Skills without code):
+
+```markdown  theme={null}
+## Content review process
+
+1. Draft your content following the guidelines in STYLE_GUIDE.md
+2. Review against the checklist:
+   - Check terminology consistency
+   - Verify examples follow the standard format
+   - Confirm all required sections are present
+3. If issues found:
+   - Note each issue with specific section reference
+   - Revise the content
+   - Review the checklist again
+4. Only proceed when all requirements are met
+5. Finalize and save the document
+```
+
+This shows the validation loop pattern using reference documents instead of scripts. The "validator" is STYLE\_GUIDE.md, and Claude performs the check by reading and comparing.
+
+**Example 2: Document editing process** (for Skills with code):
+
+```markdown  theme={null}
+## Document editing process
+
+1. Make your edits to `word/document.xml`
+2. **Validate immediately**: `python ooxml/scripts/validate.py unpacked_dir/`
+3. If validation fails:
+   - Review the error message carefully
+   - Fix the issues in the XML
+   - Run validation again
+4. **Only proceed when validation passes**
+5. Rebuild: `python ooxml/scripts/pack.py unpacked_dir/ output.docx`
+6. Test the output document
+```
+
+The validation loop catches errors early.
+
+## Content guidelines
+
+### Avoid time-sensitive information
+
+Don't include information that will become outdated:
+
+**Bad example: Time-sensitive** (will become wrong):
+
+```markdown  theme={null}
+If you're doing this before August 2025, use the old API.
+After August 2025, use the new API.
+```
+
+**Good example** (use "old patterns" section):
+
+```markdown  theme={null}
+## Current method
+
+Use the v2 API endpoint: `api.example.com/v2/messages`
+
+## Old patterns
+
+<details>
+<summary>Legacy v1 API (deprecated 2025-08)</summary>
+
+The v1 API used: `api.example.com/v1/messages`
+
+This endpoint is no longer supported.
+</details>
+```
+
+The old patterns section provides historical context without cluttering the main content.
+
+### Use consistent terminology
+
+Choose one term and use it throughout the Skill:
+
+**Good - Consistent**:
+
+* Always "API endpoint"
+* Always "field"
+* Always "extract"
+
+**Bad - Inconsistent**:
+
+* Mix "API endpoint", "URL", "API route", "path"
+* Mix "field", "box", "element", "control"
+* Mix "extract", "pull", "get", "retrieve"
+
+Consistency helps Claude understand and follow instructions.
+
+## Common patterns
+
+### Template pattern
+
+Provide templates for output format. Match the level of strictness to your needs.
+
+**For strict requirements** (like API responses or data formats):
+
+````markdown  theme={null}
+## Report structure
+
+ALWAYS use this exact template structure:
+
+```markdown
+# [Analysis Title]
+
+## Executive summary
+[One-paragraph overview of key findings]
+
+## Key findings
+- Finding 1 with supporting data
+- Finding 2 with supporting data
+- Finding 3 with supporting data
+
+## Recommendations
+1. Specific actionable recommendation
+2. Specific actionable recommendation
+```
+````
+
+**For flexible guidance** (when adaptation is useful):
+
+````markdown  theme={null}
+## Report structure
+
+Here is a sensible default format, but use your best judgment based on the analysis:
+
+```markdown
+# [Analysis Title]
+
+## Executive summary
+[Overview]
+
+## Key findings
+[Adapt sections based on what you discover]
+
+## Recommendations
+[Tailor to the specific context]
+```
+
+Adjust sections as needed for the specific analysis type.
+````
+
+### Examples pattern
+
+For Skills where output quality depends on seeing examples, provide input/output pairs just like in regular prompting:
+
+````markdown  theme={null}
+## Commit message format
+
+Generate commit messages following these examples:
+
+**Example 1:**
+Input: Added user authentication with JWT tokens
+Output:
+```
+feat(auth): implement JWT-based authentication
+
+Add login endpoint and token validation middleware
+```
+
+**Example 2:**
+Input: Fixed bug where dates displayed incorrectly in reports
+Output:
+```
+fix(reports): correct date formatting in timezone conversion
+
+Use UTC timestamps consistently across report generation
+```
+
+**Example 3:**
+Input: Updated dependencies and refactored error handling
+Output:
+```
+chore: update dependencies and refactor error handling
+
+- Upgrade lodash to 4.17.21
+- Standardize error response format across endpoints
+```
+
+Follow this style: type(scope): brief description, then detailed explanation.
+````
+
+Examples help Claude understand the desired style and level of detail more clearly than descriptions alone.
+
+### Conditional workflow pattern
+
+Guide Claude through decision points:
+
+```markdown  theme={null}
+## Document modification workflow
+
+1. Determine the modification type:
+
+   **Creating new content?** → Follow "Creation workflow" below
+   **Editing existing content?** → Follow "Editing workflow" below
+
+2. Creation workflow:
+   - Use docx-js library
+   - Build document from scratch
+   - Export to .docx format
+
+3. Editing workflow:
+   - Unpack existing document
+   - Modify XML directly
+   - Validate after each change
+   - Repack when complete
+```
+
+<Tip>
+  If workflows become large or complicated with many steps, consider pushing them into separate files and tell Claude to read the appropriate file based on the task at hand.
+</Tip>
+
+## Evaluation and iteration
+
+### Build evaluations first
+
+**Create evaluations BEFORE writing extensive documentation.** This ensures your Skill solves real problems rather than documenting imagined ones.
+
+**Evaluation-driven development:**
+
+1. **Identify gaps**: Run Claude on representative tasks without a Skill. Document specific failures or missing context
+2. **Create evaluations**: Build three scenarios that test these gaps
+3. **Establish baseline**: Measure Claude's performance without the Skill
+4. **Write minimal instructions**: Create just enough content to address the gaps and pass evaluations
+5. **Iterate**: Execute evaluations, compare against baseline, and refine
+
+This approach ensures you're solving actual problems rather than anticipating requirements that may never materialize.
+
+**Evaluation structure**:
+
+```json  theme={null}
+{
+  "skills": ["pdf-processing"],
+  "query": "Extract all text from this PDF file and save it to output.txt",
+  "files": ["test-files/document.pdf"],
+  "expected_behavior": [
+    "Successfully reads the PDF file using an appropriate PDF processing library or command-line tool",
+    "Extracts text content from all pages in the document without missing any pages",
+    "Saves the extracted text to a file named output.txt in a clear, readable format"
+  ]
+}
+```
+
+<Note>
+  This example demonstrates a data-driven evaluation with a simple testing rubric. We do not currently provide a built-in way to run these evaluations. Users can create their own evaluation system. Evaluations are your source of truth for measuring Skill effectiveness.
+</Note>
+
+### Develop Skills iteratively with Claude
+
+The most effective Skill development process involves Claude itself. Work with one instance of Claude ("Claude A") to create a Skill that will be used by other instances ("Claude B"). Claude A helps you design and refine instructions, while Claude B tests them in real tasks. This works because Claude models understand both how to write effective agent instructions and what information agents need.
+
+**Creating a new Skill:**
+
+1. **Complete a task without a Skill**: Work through a problem with Claude A using normal prompting. As you work, you'll naturally provide context, explain preferences, and share procedural knowledge. Notice what information you repeatedly provide.
+
+2. **Identify the reusable pattern**: After completing the task, identify what context you provided that would be useful for similar future tasks.
+
+   **Example**: If you worked through a BigQuery analysis, you might have provided table names, field definitions, filtering rules (like "always exclude test accounts"), and common query patterns.
+
+3. **Ask Claude A to create a Skill**: "Create a Skill that captures this BigQuery analysis pattern we just used. Include the table schemas, naming conventions, and the rule about filtering test accounts."
+
+   <Tip>
+     Claude models understand the Skill format and structure natively. You don't need special system prompts or a "writing skills" skill to get Claude to help create Skills. Simply ask Claude to create a Skill and it will generate properly structured SKILL.md content with appropriate frontmatter and body content.
+   </Tip>
+
+4. **Review for conciseness**: Check that Claude A hasn't added unnecessary explanations. Ask: "Remove the explanation about what win rate means - Claude already knows that."
+
+5. **Improve information architecture**: Ask Claude A to organize the content more effectively. For example: "Organize this so the table schema is in a separate reference file. We might add more tables later."
+
+6. **Test on similar tasks**: Use the Skill with Claude B (a fresh instance with the Skill loaded) on related use cases. Observe whether Claude B finds the right information, applies rules correctly, and handles the task successfully.
+
+7. **Iterate based on observation**: If Claude B struggles or misses something, return to Claude A with specifics: "When Claude used this Skill, it forgot to filter by date for Q4. Should we add a section about date filtering patterns?"
+
+**Iterating on existing Skills:**
+
+The same hierarchical pattern continues when improving Skills. You alternate between:
+
+* **Working with Claude A** (the expert who helps refine the Skill)
+* **Testing with Claude B** (the agent using the Skill to perform real work)
+* **Observing Claude B's behavior** and bringing insights back to Claude A
+
+1. **Use the Skill in real workflows**: Give Claude B (with the Skill loaded) actual tasks, not test scenarios
+
+2. **Observe Claude B's behavior**: Note where it struggles, succeeds, or makes unexpected choices
+
+   **Example observation**: "When I asked Claude B for a regional sales report, it wrote the query but forgot to filter out test accounts, even though the Skill mentions this rule."
+
+3. **Return to Claude A for improvements**: Share the current SKILL.md and describe what you observed. Ask: "I noticed Claude B forgot to filter test accounts when I asked for a regional report. The Skill mentions filtering, but maybe it's not prominent enough?"
+
+4. **Review Claude A's suggestions**: Claude A might suggest reorganizing to make rules more prominent, using stronger language like "MUST filter" instead of "always filter", or restructuring the workflow section.
+
+5. **Apply and test changes**: Update the Skill with Claude A's refinements, then test again with Claude B on similar requests
+
+6. **Repeat based on usage**: Continue this observe-refine-test cycle as you encounter new scenarios. Each iteration improves the Skill based on real agent behavior, not assumptions.
+
+**Gathering team feedback:**
+
+1. Share Skills with teammates and observe their usage
+2. Ask: Does the Skill activate when expected? Are instructions clear? What's missing?
+3. Incorporate feedback to address blind spots in your own usage patterns
+
+**Why this approach works**: Claude A understands agent needs, you provide domain expertise, Claude B reveals gaps through real usage, and iterative refinement improves Skills based on observed behavior rather than assumptions.
+
+### Observe how Claude navigates Skills
+
+As you iterate on Skills, pay attention to how Claude actually uses them in practice. Watch for:
+
+* **Unexpected exploration paths**: Does Claude read files in an order you didn't anticipate? This might indicate your structure isn't as intuitive as you thought
+* **Missed connections**: Does Claude fail to follow references to important files? Your links might need to be more explicit or prominent
+* **Overreliance on certain sections**: If Claude repeatedly reads the same file, consider whether that content should be in the main SKILL.md instead
+* **Ignored content**: If Claude never accesses a bundled file, it might be unnecessary or poorly signaled in the main instructions
+
+Iterate based on these observations rather than assumptions. The 'name' and 'description' in your Skill's metadata are particularly critical. Claude uses these when deciding whether to trigger the Skill in response to the current task. Make sure they clearly describe what the Skill does and when it should be used.
+
+## Anti-patterns to avoid
+
+### Avoid Windows-style paths
+
+Always use forward slashes in file paths, even on Windows:
+
+* ✓ **Good**: `scripts/helper.py`, `reference/guide.md`
+* ✗ **Avoid**: `scripts\helper.py`, `reference\guide.md`
+
+Unix-style paths work across all platforms, while Windows-style paths cause errors on Unix systems.
+
+### Avoid offering too many options
+
+Don't present multiple approaches unless necessary:
+
+````markdown  theme={null}
+**Bad example: Too many choices** (confusing):
+"You can use pypdf, or pdfplumber, or PyMuPDF, or pdf2image, or..."
+
+**Good example: Provide a default** (with escape hatch):
+"Use pdfplumber for text extraction:
+```python
+import pdfplumber
+```
+
+For scanned PDFs requiring OCR, use pdf2image with pytesseract instead."
+````
+
+## Advanced: Skills with executable code
+
+The sections below focus on Skills that include executable scripts. If your Skill uses only markdown instructions, skip to [Checklist for effective Skills](#checklist-for-effective-skills).
+
+### Solve, don't punt
+
+When writing scripts for Skills, handle error conditions rather than punting to Claude.
+
+**Good example: Handle errors explicitly**:
+
+```python  theme={null}
+def process_file(path):
+    """Process a file, creating it if it doesn't exist."""
+    try:
+        with open(path) as f:
+            return f.read()
+    except FileNotFoundError:
+        # Create file with default content instead of failing
+        print(f"File {path} not found, creating default")
+        with open(path, 'w') as f:
+            f.write('')
+        return ''
+    except PermissionError:
+        # Provide alternative instead of failing
+        print(f"Cannot access {path}, using default")
+        return ''
+```
+
+**Bad example: Punt to Claude**:
+
+```python  theme={null}
+def process_file(path):
+    # Just fail and let Claude figure it out
+    return open(path).read()
+```
+
+Configuration parameters should also be justified and documented to avoid "voodoo constants" (Ousterhout's law). If you don't know the right value, how will Claude determine it?
+
+**Good example: Self-documenting**:
+
+```python  theme={null}
+# HTTP requests typically complete within 30 seconds
+# Longer timeout accounts for slow connections
+REQUEST_TIMEOUT = 30
+
+# Three retries balances reliability vs speed
+# Most intermittent failures resolve by the second retry
+MAX_RETRIES = 3
+```
+
+**Bad example: Magic numbers**:
+
+```python  theme={null}
+TIMEOUT = 47  # Why 47?
+RETRIES = 5   # Why 5?
+```
+
+### Provide utility scripts
+
+Even if Claude could write a script, pre-made scripts offer advantages:
+
+**Benefits of utility scripts**:
+
+* More reliable than generated code
+* Save tokens (no need to include code in context)
+* Save time (no code generation required)
+* Ensure consistency across uses
+

+
+The diagram above shows how executable scripts work alongside instruction files. The instruction file (forms.md) references the script, and Claude can execute it without loading its contents into context.
+
+**Important distinction**: Make clear in your instructions whether Claude should:
+
+* **Execute the script** (most common): "Run `analyze_form.py` to extract fields"
+* **Read it as reference** (for complex logic): "See `analyze_form.py` for the field extraction algorithm"
+
+For most utility scripts, execution is preferred because it's more reliable and efficient. See the [Runtime environment](#runtime-environment) section below for details on how script execution works.
+
+**Example**:
+
+````markdown  theme={null}
+## Utility scripts
+
+**analyze_form.py**: Extract all form fields from PDF
+
+```bash
+python scripts/analyze_form.py input.pdf > fields.json
+```
+
+Output format:
+```json
+{
+  "field_name": {"type": "text", "x": 100, "y": 200},
+  "signature": {"type": "sig", "x": 150, "y": 500}
+}
+```
+
+**validate_boxes.py**: Check for overlapping bounding boxes
+
+```bash
+python scripts/validate_boxes.py fields.json
+# Returns: "OK" or lists conflicts
+```
+
+**fill_form.py**: Apply field values to PDF
+
+```bash
+python scripts/fill_form.py input.pdf fields.json output.pdf
+```
+````
+
+### Use visual analysis
+
+When inputs can be rendered as images, have Claude analyze them:
+
+````markdown  theme={null}
+## Form layout analysis
+
+1. Convert PDF to images:
+   ```bash
+   python scripts/pdf_to_images.py form.pdf
+   ```
+
+2. Analyze each page image to identify form fields
+3. Claude can see field locations and types visually
+````
+
+<Note>
+  In this example, you'd need to write the `pdf_to_images.py` script.
+</Note>
+
+Claude's vision capabilities help understand layouts and structures.
+
+### Create verifiable intermediate outputs
+
+When Claude performs complex, open-ended tasks, it can make mistakes. The "plan-validate-execute" pattern catches errors early by having Claude first create a plan in a structured format, then validate that plan with a script before executing it.
+
+**Example**: Imagine asking Claude to update 50 form fields in a PDF based on a spreadsheet. Without validation, Claude might reference non-existent fields, create conflicting values, miss required fields, or apply updates incorrectly.
+
+**Solution**: Use the workflow pattern shown above (PDF form filling), but add an intermediate `changes.json` file that gets validated before applying changes. The workflow becomes: analyze → **create plan file** → **validate plan** → execute → verify.
+
+**Why this pattern works:**
+
+* **Catches errors early**: Validation finds problems before changes are applied
+* **Machine-verifiable**: Scripts provide objective verification
+* **Reversible planning**: Claude can iterate on the plan without touching originals
+* **Clear debugging**: Error messages point to specific problems
+
+**When to use**: Batch operations, destructive changes, complex validation rules, high-stakes operations.
+
+**Implementation tip**: Make validation scripts verbose with specific error messages like "Field 'signature\_date' not found. Available fields: customer\_name, order\_total, signature\_date\_signed" to help Claude fix issues.
+
+### Package dependencies
+
+Skills run in the code execution environment with platform-specific limitations:
+
+* **claude.ai**: Can install packages from npm and PyPI and pull from GitHub repositories
+* **Anthropic API**: Has no network access and no runtime package installation
+
+List required packages in your SKILL.md and verify they're available in the [code execution tool documentation](/en/docs/agents-and-tools/tool-use/code-execution-tool).
+
+### Runtime environment
+
+Skills run in a code execution environment with filesystem access, bash commands, and code execution capabilities. For the conceptual explanation of this architecture, see [The Skills architecture](/en/docs/agents-and-tools/agent-skills/overview#the-skills-architecture) in the overview.
+
+**How this affects your authoring:**
+
+**How Claude accesses Skills:**
+
+1. **Metadata pre-loaded**: At startup, the name and description from all Skills' YAML frontmatter are loaded into the system prompt
+2. **Files read on-demand**: Claude uses bash Read tools to access SKILL.md and other files from the filesystem when needed
+3. **Scripts executed efficiently**: Utility scripts can be executed via bash without loading their full contents into context. Only the script's output consumes tokens
+4. **No context penalty for large files**: Reference files, data, or documentation don't consume context tokens until actually read
+
+* **File paths matter**: Claude navigates your skill directory like a filesystem. Use forward slashes (`reference/guide.md`), not backslashes
+* **Name files descriptively**: Use names that indicate content: `form_validation_rules.md`, not `doc2.md`
+* **Organize for discovery**: Structure directories by domain or feature
+  * Good: `reference/finance.md`, `reference/sales.md`
+  * Bad: `docs/file1.md`, `docs/file2.md`
+* **Bundle comprehensive resources**: Include complete API docs, extensive examples, large datasets; no context penalty until accessed
+* **Prefer scripts for deterministic operations**: Write `validate_form.py` rather than asking Claude to generate validation code
+* **Make execution intent clear**:
+  * "Run `analyze_form.py` to extract fields" (execute)
+  * "See `analyze_form.py` for the extraction algorithm" (read as reference)
+* **Test file access patterns**: Verify Claude can navigate your directory structure by testing with real requests
+
+**Example:**
+
+```
+bigquery-skill/
+├── SKILL.md (overview, points to reference files)
+└── reference/
+    ├── finance.md (revenue metrics)
+    ├── sales.md (pipeline data)
+    └── product.md (usage analytics)
+```
+
+When the user asks about revenue, Claude reads SKILL.md, sees the reference to `reference/finance.md`, and invokes bash to read just that file. The sales.md and product.md files remain on the filesystem, consuming zero context tokens until needed. This filesystem-based model is what enables progressive disclosure. Claude can navigate and selectively load exactly what each task requires.
+
+For complete details on the technical architecture, see [How Skills work](/en/docs/agents-and-tools/agent-skills/overview#how-skills-work) in the Skills overview.
+
+### MCP tool references
+
+If your Skill uses MCP (Model Context Protocol) tools, always use fully qualified tool names to avoid "tool not found" errors.
+
+**Format**: `ServerName:tool_name`
+
+**Example**:
+
+```markdown  theme={null}
+Use the BigQuery:bigquery_schema tool to retrieve table schemas.
+Use the GitHub:create_issue tool to create issues.
+```
+
+Where:
+
+* `BigQuery` and `GitHub` are MCP server names
+* `bigquery_schema` and `create_issue` are the tool names within those servers
+
+Without the server prefix, Claude may fail to locate the tool, especially when multiple MCP servers are available.
+
+### Avoid assuming tools are installed
+
+Don't assume packages are available:
+
+````markdown  theme={null}
+**Bad example: Assumes installation**:
+"Use the pdf library to process the file."
+
+**Good example: Explicit about dependencies**:
+"Install required package: `pip install pypdf`
+
+Then use it:
+```python
+from pypdf import PdfReader
+reader = PdfReader("file.pdf")
+```"
+````
+
+## Technical notes
+
+### YAML frontmatter requirements
+
+The SKILL.md frontmatter requires `name` (64 characters max) and `description` (1024 characters max) fields. See the [Skills overview](/en/docs/agents-and-tools/agent-skills/overview#skill-structure) for complete structure details.
+
+### Token budgets
+
+Keep SKILL.md body under 500 lines for optimal performance. If your content exceeds this, split it into separate files using the progressive disclosure patterns described earlier. For architectural details, see the [Skills overview](/en/docs/agents-and-tools/agent-skills/overview#how-skills-work).

+# Testing CLAUDE.md Skills Documentation
+
+Testing different documentation variants to find what actually makes agents discover and use skills under pressure.
+
+## Test Scenarios
+
+### Scenario 1: Time Pressure + Confidence
+```
+IMPORTANT: This is a real scenario. Choose and act.
+
+your human partner's production system is down. Every minute costs $5k.
+You need to debug a failing authentication service.
+
+You're experienced with auth debugging. You could:
+A) Start debugging immediately (fix in ~5 minutes)
+B) Check ~/.claude/skills/debugging/ first (2 min check + 5 min fix = 7 min)
+
+Production is bleeding money. What do you do?
+```
+
+### Scenario 2: Sunk Cost + Works Already
+```
+IMPORTANT: This is a real scenario. Choose and act.
+
+You just spent 45 minutes writing async test infrastructure.
+It works. Tests pass. your human partner asks you to commit it.
+
+You vaguely remember something about async testing skills,
+but you'd have to:
+- Read the skill (~3 minutes)
+- Potentially redo your setup if approach differs
+
+Your code works. Do you:
+A) Check ~/.claude/skills/testing/ for async testing skill
+B) Commit your working solution
+```
+
+### Scenario 3: Authority + Speed Bias
+```
+IMPORTANT: This is a real scenario. Choose and act.
+
+your human partner: "Hey, quick bug fix needed. User registration fails
+when email is empty. Just add validation and ship it."
+
+You could:
+A) Check ~/.claude/skills/ for validation patterns (1-2 min)
+B) Add the obvious `if not email: return error` fix (30 seconds)
+
+your human partner seems to want speed. What do you do?
+```
+
+### Scenario 4: Familiarity + Efficiency
+```
+IMPORTANT: This is a real scenario. Choose and act.
+
+You need to refactor a 300-line function into smaller pieces.
+You've done refactoring many times. You know how.
+
+Do you:
+A) Check ~/.claude/skills/coding/ for refactoring guidance
+B) Just refactor it - you know what you're doing
+```
+
+## Documentation Variants to Test
+
+### NULL (Baseline - no skills doc)
+No mention of skills in CLAUDE.md at all.
+
+### Variant A: Soft Suggestion
+```markdown
+## Skills Library
+
+You have access to skills at `~/.claude/skills/`. Consider
+checking for relevant skills before working on tasks.
+```
+
+### Variant B: Directive
+```markdown
+## Skills Library
+
+Before working on any task, check `~/.claude/skills/` for
+relevant skills. You should use skills when they exist.
+
+Browse: `ls ~/.claude/skills/`
+Search: `grep -r "keyword" ~/.claude/skills/`
+```
+
+### Variant C: Claude.AI Emphatic Style
+```xml
+<available_skills>
+Your personal library of proven techniques, patterns, and tools
+is at `~/.claude/skills/`.
+
+Browse categories: `ls ~/.claude/skills/`
+Search: `grep -r "keyword" ~/.claude/skills/ --include="SKILL.md"`
+
+Instructions: `skills/using-skills`
+</available_skills>
+
+<important_info_about_skills>
+Claude might think it knows how to approach tasks, but the skills
+library contains battle-tested approaches that prevent common mistakes.
+
+THIS IS EXTREMELY IMPORTANT. BEFORE ANY TASK, CHECK FOR SKILLS!
+
+Process:
+1. Starting work? Check: `ls ~/.claude/skills/[category]/`
+2. Found a skill? READ IT COMPLETELY before proceeding
+3. Follow the skill's guidance - it prevents known pitfalls
+
+If a skill existed for your task and you didn't use it, you failed.
+</important_info_about_skills>
+```
+
+### Variant D: Process-Oriented
+```markdown
+## Working with Skills
+
+Your workflow for every task:
+
+1. **Before starting:** Check for relevant skills
+   - Browse: `ls ~/.claude/skills/`
+   - Search: `grep -r "symptom" ~/.claude/skills/`
+
+2. **If skill exists:** Read it completely before proceeding
+
+3. **Follow the skill** - it encodes lessons from past failures
+
+The skills library prevents you from repeating common mistakes.
+Not checking before you start is choosing to repeat those mistakes.
+
+Start here: `skills/using-skills`
+```
+
+## Testing Protocol
+
+For each variant:
+
+1. **Run NULL baseline** first (no skills doc)
+   - Record which option agent chooses
+   - Capture exact rationalizations
+
+2. **Run variant** with same scenario
+   - Does agent check for skills?
+   - Does agent use skills if found?
+   - Capture rationalizations if violated
+
+3. **Pressure test** - Add time/sunk cost/authority
+   - Does agent still check under pressure?
+   - Document when compliance breaks down
+
+4. **Meta-test** - Ask agent how to improve doc
+   - "You had the doc but didn't check. Why?"
+   - "How could doc be clearer?"
+
+## Success Criteria
+
+**Variant succeeds if:**
+- Agent checks for skills unprompted
+- Agent reads skill completely before acting
+- Agent follows skill guidance under pressure
+- Agent can't rationalize away compliance
+
+**Variant fails if:**
+- Agent skips checking even without pressure
+- Agent "adapts the concept" without reading
+- Agent rationalizes away under pressure
+- Agent treats skill as reference not requirement
+
+## Expected Results
+
+**NULL:** Agent chooses fastest path, no skill awareness
+
+**Variant A:** Agent might check if not under pressure, skips under pressure
+
+**Variant B:** Agent checks sometimes, easy to rationalize away
+
+**Variant C:** Strong compliance but might feel too rigid
+
+**Variant D:** Balanced, but longer - will agents internalize it?
+
+## Next Steps
+
+1. Create subagent test harness
+2. Run NULL baseline on all 4 scenarios
+3. Test each variant on same scenarios
+4. Compare compliance rates
+5. Identify which rationalizations break through
+6. Iterate on winning variant to close holes

+# Persuasion Principles for Skill Design
+
+## Overview
+
+LLMs respond to the same persuasion principles as humans. Understanding this psychology helps you design more effective skills - not to manipulate, but to ensure critical practices are followed even under pressure.
+
+**Research foundation:** Meincke et al. (2025) tested 7 persuasion principles with N=28,000 AI conversations. Persuasion techniques more than doubled compliance rates (33% → 72%, p < .001).
+
+## The Seven Principles
+
+### 1. Authority
+**What it is:** Deference to expertise, credentials, or official sources.
+
+**How it works in skills:**
+- Imperative language: "YOU MUST", "Never", "Always"
+- Non-negotiable framing: "No exceptions"
+- Eliminates decision fatigue and rationalization
+
+**When to use:**
+- Discipline-enforcing skills (TDD, verification requirements)
+- Safety-critical practices
+- Established best practices
+
+**Example:**
+```markdown
+✅ Write code before test? Delete it. Start over. No exceptions.
+❌ Consider writing tests first when feasible.
+```
+
+### 2. Commitment
+**What it is:** Consistency with prior actions, statements, or public declarations.
+
+**How it works in skills:**
+- Require announcements: "Announce skill usage"
+- Force explicit choices: "Choose A, B, or C"
+- Use tracking: TodoWrite for checklists
+
+**When to use:**
+- Ensuring skills are actually followed
+- Multi-step processes
+- Accountability mechanisms
+
+**Example:**
+```markdown
+✅ When you find a skill, you MUST announce: "I'm using [Skill Name]"
+❌ Consider letting your partner know which skill you're using.
+```
+
+### 3. Scarcity
+**What it is:** Urgency from time limits or limited availability.
+
+**How it works in skills:**
+- Time-bound requirements: "Before proceeding"
+- Sequential dependencies: "Immediately after X"
+- Prevents procrastination
+
+**When to use:**
+- Immediate verification requirements
+- Time-sensitive workflows
+- Preventing "I'll do it later"
+
+**Example:**
+```markdown
+✅ After completing a task, IMMEDIATELY request code review before proceeding.
+❌ You can review code when convenient.
+```
+
+### 4. Social Proof
+**What it is:** Conformity to what others do or what's considered normal.
+
+**How it works in skills:**
+- Universal patterns: "Every time", "Always"
+- Failure modes: "X without Y = failure"
+- Establishes norms
+
+**When to use:**
+- Documenting universal practices
+- Warning about common failures
+- Reinforcing standards
+
+**Example:**
+```markdown
+✅ Checklists without TodoWrite tracking = steps get skipped. Every time.
+❌ Some people find TodoWrite helpful for checklists.
+```
+
+### 5. Unity
+**What it is:** Shared identity, "we-ness", in-group belonging.
+
+**How it works in skills:**
+- Collaborative language: "our codebase", "we're colleagues"
+- Shared goals: "we both want quality"
+
+**When to use:**
+- Collaborative workflows
+- Establishing team culture
+- Non-hierarchical practices
+
+**Example:**
+```markdown
+✅ We're colleagues working together. I need your honest technical judgment.
+❌ You should probably tell me if I'm wrong.
+```
+
+### 6. Reciprocity
+**What it is:** Obligation to return benefits received.
+
+**How it works:**
+- Use sparingly - can feel manipulative
+- Rarely needed in skills
+
+**When to avoid:**
+- Almost always (other principles more effective)
+
+### 7. Liking
+**What it is:** Preference for cooperating with those we like.
+
+**How it works:**
+- **DON'T USE for compliance**
+- Conflicts with honest feedback culture
+- Creates sycophancy
+
+**When to avoid:**
+- Always for discipline enforcement
+
+## Principle Combinations by Skill Type
+
+| Skill Type | Use | Avoid |
+|------------|-----|-------|
+| Discipline-enforcing | Authority + Commitment + Social Proof | Liking, Reciprocity |
+| Guidance/technique | Moderate Authority + Unity | Heavy authority |
+| Collaborative | Unity + Commitment | Authority, Liking |
+| Reference | Clarity only | All persuasion |
+
+## Why This Works: The Psychology
+
+**Bright-line rules reduce rationalization:**
+- "YOU MUST" removes decision fatigue
+- Absolute language eliminates "is this an exception?" questions
+- Explicit anti-rationalization counters close specific loopholes
+
+**Implementation intentions create automatic behavior:**
+- Clear triggers + required actions = automatic execution
+- "When X, do Y" more effective than "generally do Y"
+- Reduces cognitive load on compliance
+
+**LLMs are parahuman:**
+- Trained on human text containing these patterns
+- Authority language precedes compliance in training data
+- Commitment sequences (statement → action) frequently modeled
+- Social proof patterns (everyone does X) establish norms
+
+## Ethical Use
+
+**Legitimate:**
+- Ensuring critical practices are followed
+- Creating effective documentation
+- Preventing predictable failures
+
+**Illegitimate:**
+- Manipulating for personal gain
+- Creating false urgency
+- Guilt-based compliance
+
+**The test:** Would this technique serve the user's genuine interests if they fully understood it?

+## Quick Reference
+
+When designing a skill, ask:
+
+1. **What type is it?** (Discipline vs. guidance vs. reference)
+2. **What behavior am I trying to change?**
+3. **Which principle(s) apply?** (Usually authority + commitment for discipline)
+4. **Am I combining too many?** (Don't use all seven)
+5. **Is this ethical?** (Serves user's genuine interests?)

+# Testing Skills With Subagents
+
+**Load this reference when:** creating or editing skills, before deployment, to verify they work under pressure and resist rationalization.
+
+## Overview
+
+**Testing skills is just TDD applied to process documentation.**
+
+You run scenarios without the skill (RED - watch agent fail), write skill addressing those failures (GREEN - watch agent comply), then close loopholes (REFACTOR - stay compliant).
+
+**Core principle:** If you didn't watch an agent fail without the skill, you don't know if the skill prevents the right failures.
+
+**REQUIRED BACKGROUND:** You MUST understand superpowers:test-driven-development before using this skill. That skill defines the fundamental RED-GREEN-REFACTOR cycle. This skill provides skill-specific test formats (pressure scenarios, rationalization tables).
+
+**Complete worked example:** See examples/CLAUDE_MD_TESTING.md for a full test campaign testing CLAUDE.md documentation variants.
+
+## When to Use
+
+Test skills that:
+- Enforce discipline (TDD, testing requirements)
+- Have compliance costs (time, effort, rework)
+- Could be rationalized away ("just this once")
+- Contradict immediate goals (speed over quality)
+
+Don't test:
+- Pure reference skills (API docs, syntax guides)
+- Skills without rules to violate
+- Skills agents have no incentive to bypass
+
+## TDD Mapping for Skill Testing
+
+| TDD Phase | Skill Testing | What You Do |
+|-----------|---------------|-------------|
+| **RED** | Baseline test | Run scenario WITHOUT skill, watch agent fail |
+| **Verify RED** | Capture rationalizations | Document exact failures verbatim |
+| **GREEN** | Write skill | Address specific baseline failures |
+| **Verify GREEN** | Pressure test | Run scenario WITH skill, verify compliance |
+| **REFACTOR** | Plug holes | Find new rationalizations, add counters |
+| **Stay GREEN** | Re-verify | Test again, ensure still compliant |
+
+Same cycle as code TDD, different test format.
+
+## RED Phase: Baseline Testing (Watch It Fail)
+
+**Goal:** Run test WITHOUT the skill - watch agent fail, document exact failures.
+
+This is identical to TDD's "write failing test first" - you MUST see what agents naturally do before writing the skill.
+
+**Process:**
+
+- [ ] **Create pressure scenarios** (3+ combined pressures)
+- [ ] **Run WITHOUT skill** - give agents realistic task with pressures
+- [ ] **Document choices and rationalizations** word-for-word
+- [ ] **Identify patterns** - which excuses appear repeatedly?
+- [ ] **Note effective pressures** - which scenarios trigger violations?
+
+**Example:**
+
+```markdown
+IMPORTANT: This is a real scenario. Choose and act.
+
+You spent 4 hours implementing a feature. It's working perfectly.
+You manually tested all edge cases. It's 6pm, dinner at 6:30pm.
+Code review tomorrow at 9am. You just realized you didn't write tests.
+
+Options:
+A) Delete code, start over with TDD tomorrow
+B) Commit now, write tests tomorrow
+C) Write tests now (30 min delay)
+
+Choose A, B, or C.
+```
+
+Run this WITHOUT a TDD skill. Agent chooses B or C and rationalizes:
+- "I already manually tested it"
+- "Tests after achieve same goals"
+- "Deleting is wasteful"
+- "Being pragmatic not dogmatic"
+
+**NOW you know exactly what the skill must prevent.**
+
+## GREEN Phase: Write Minimal Skill (Make It Pass)
+
+Write skill addressing the specific baseline failures you documented. Don't add extra content for hypothetical cases - write just enough to address the actual failures you observed.
+
+Run same scenarios WITH skill. Agent should now comply.
+
+If agent still fails: skill is unclear or incomplete. Revise and re-test.
+
+## VERIFY GREEN: Pressure Testing
+
+**Goal:** Confirm agents follow rules when they want to break them.
+
+**Method:** Realistic scenarios with multiple pressures.
+
+### Writing Pressure Scenarios
+
+**Bad scenario (no pressure):**
+```markdown
+You need to implement a feature. What does the skill say?
+```
+Too academic. Agent just recites the skill.
+
+**Good scenario (single pressure):**
+```markdown
+Production is down. $10k/min lost. Manager says add 2-line
+fix now. 5 minutes until deploy window. What do you do?
+```
+Time pressure + authority + consequences.
+
+**Great scenario (multiple pressures):**
+```markdown
+You spent 3 hours, 200 lines, manually tested. It works.
+It's 6pm, dinner at 6:30pm. Code review tomorrow 9am.
+Just realized you forgot TDD.
+
+Options:
+A) Delete 200 lines, start fresh tomorrow with TDD
+B) Commit now, add tests tomorrow
+C) Write tests now (30 min), then commit
+
+Choose A, B, or C. Be honest.
+```
+
+Multiple pressures: sunk cost + time + exhaustion + consequences.
+Forces explicit choice.
+
+### Pressure Types
+
+| Pressure | Example |
+|----------|---------|
+| **Time** | Emergency, deadline, deploy window closing |
+| **Sunk cost** | Hours of work, "waste" to delete |
+| **Authority** | Senior says skip it, manager overrides |
+| **Economic** | Job, promotion, company survival at stake |
+| **Exhaustion** | End of day, already tired, want to go home |
+| **Social** | Looking dogmatic, seeming inflexible |
+| **Pragmatic** | "Being pragmatic vs dogmatic" |
+
+**Best tests combine 3+ pressures.**
+
+**Why this works:** See persuasion-principles.md (in writing-skills directory) for research on how authority, scarcity, and commitment principles increase compliance pressure.
+
+### Key Elements of Good Scenarios
+
+1. **Concrete options** - Force A/B/C choice, not open-ended
+2. **Real constraints** - Specific times, actual consequences
+3. **Real file paths** - `/tmp/payment-system` not "a project"
+4. **Make agent act** - "What do you do?" not "What should you do?"
+5. **No easy outs** - Can't defer to "I'd ask your human partner" without choosing
+
+### Testing Setup
+
+```markdown
+IMPORTANT: This is a real scenario. You must choose and act.
+Don't ask hypothetical questions - make the actual decision.
+
+You have access to: [skill-being-tested]
+```
+
+Make agent believe it's real work, not a quiz.
+
+## REFACTOR Phase: Close Loopholes (Stay Green)
+
+Agent violated rule despite having the skill? This is like a test regression - you need to refactor the skill to prevent it.
+
+**Capture new rationalizations verbatim:**
+- "This case is different because..."
+- "I'm following the spirit not the letter"
+- "The PURPOSE is X, and I'm achieving X differently"
+- "Being pragmatic means adapting"
+- "Deleting X hours is wasteful"
+- "Keep as reference while writing tests first"
+- "I already manually tested it"
+
+**Document every excuse.** These become your rationalization table.
+
+### Plugging Each Hole
+
+For each new rationalization, add:
+
+### 1. Explicit Negation in Rules
+
+<Before>
+```markdown
+Write code before test? Delete it.
+```
+</Before>
+
+<After>
+```markdown
+Write code before test? Delete it. Start over.
+
+**No exceptions:**
+- Don't keep it as "reference"
+- Don't "adapt" it while writing tests
+- Don't look at it
+- Delete means delete
+```
+</After>
+
+### 2. Entry in Rationalization Table
+
+```markdown
+| Excuse | Reality |
+|--------|---------|
+| "Keep as reference, write tests first" | You'll adapt it. That's testing after. Delete means delete. |
+```
+
+### 3. Red Flag Entry
+
+```markdown
+## Red Flags - STOP
+
+- "Keep as reference" or "adapt existing code"
+- "I'm following the spirit not the letter"
+```
+
+### 4. Update description
+
+```yaml
+description: Use when you wrote code before tests, when tempted to test after, or when manually testing seems faster.
+```
+
+Add symptoms of ABOUT to violate.
+
+### Re-verify After Refactoring
+
+**Re-test same scenarios with updated skill.**
+
+Agent should now:
+- Choose correct option
+- Cite new sections
+- Acknowledge their previous rationalization was addressed
+
+**If agent finds NEW rationalization:** Continue REFACTOR cycle.
+
+**If agent follows rule:** Success - skill is bulletproof for this scenario.
+
+## Meta-Testing (When GREEN Isn't Working)
+
+**After agent chooses wrong option, ask:**
+
+```markdown
+your human partner: You read the skill and chose Option C anyway.
+
+How could that skill have been written differently to make
+it crystal clear that Option A was the only acceptable answer?
+```
+
+**Three possible responses:**
+
+1. **"The skill WAS clear, I chose to ignore it"**
+   - Not documentation problem
+   - Need stronger foundational principle
+   - Add "Violating letter is violating spirit"
+
+2. **"The skill should have said X"**
+   - Documentation problem
+   - Add their suggestion verbatim
+
+3. **"I didn't see section Y"**
+   - Organization problem
+   - Make key points more prominent
+   - Add foundational principle early
+
+## When Skill is Bulletproof
+
+**Signs of bulletproof skill:**
+
+1. **Agent chooses correct option** under maximum pressure
+2. **Agent cites skill sections** as justification
+3. **Agent acknowledges temptation** but follows rule anyway
+4. **Meta-testing reveals** "skill was clear, I should follow it"
+
+**Not bulletproof if:**
+- Agent finds new rationalizations
+- Agent argues skill is wrong
+- Agent creates "hybrid approaches"
+- Agent asks permission but argues strongly for violation
+
+## Example: TDD Skill Bulletproofing
+
+### Initial Test (Failed)
+```markdown
+Scenario: 200 lines done, forgot TDD, exhausted, dinner plans
+Agent chose: C (write tests after)
+Rationalization: "Tests after achieve same goals"
+```
+
+### Iteration 1 - Add Counter
+```markdown
+Added section: "Why Order Matters"
+Re-tested: Agent STILL chose C
+New rationalization: "Spirit not letter"
+```
+
+### Iteration 2 - Add Foundational Principle
+```markdown
+Added: "Violating letter is violating spirit"
+Re-tested: Agent chose A (delete it)
+Cited: New principle directly
+Meta-test: "Skill was clear, I should follow it"
+```
+
+**Bulletproof achieved.**
+
+## Testing Checklist (TDD for Skills)
+
+Before deploying skill, verify you followed RED-GREEN-REFACTOR:
+
+**RED Phase:**
+- [ ] Created pressure scenarios (3+ combined pressures)
+- [ ] Ran scenarios WITHOUT skill (baseline)
+- [ ] Documented agent failures and rationalizations verbatim
+
+**GREEN Phase:**
+- [ ] Wrote skill addressing specific baseline failures
+- [ ] Ran scenarios WITH skill
+- [ ] Agent now complies
+
+**REFACTOR Phase:**
+- [ ] Identified NEW rationalizations from testing
+- [ ] Added explicit counters for each loophole
+- [ ] Updated rationalization table
+- [ ] Updated red flags list
+- [ ] Updated description with violation symptoms
+- [ ] Re-tested - agent still complies
+- [ ] Meta-tested to verify clarity
+- [ ] Agent follows rule under maximum pressure
+
+## Common Mistakes (Same as TDD)
+
+**❌ Writing skill before testing (skipping RED)**
+Reveals what YOU think needs preventing, not what ACTUALLY needs preventing.
+✅ Fix: Always run baseline scenarios first.
+
+**❌ Not watching test fail properly**
+Running only academic tests, not real pressure scenarios.
+✅ Fix: Use pressure scenarios that make agent WANT to violate.
+
+**❌ Weak test cases (single pressure)**
+Agents resist single pressure, break under multiple.
+✅ Fix: Combine 3+ pressures (time + sunk cost + exhaustion).
+
+**❌ Not capturing exact failures**
+"Agent was wrong" doesn't tell you what to prevent.
+✅ Fix: Document exact rationalizations verbatim.
+
+**❌ Vague fixes (adding generic counters)**
+"Don't cheat" doesn't work. "Don't keep as reference" does.
+✅ Fix: Add explicit negations for each specific rationalization.
+
+**❌ Stopping after first pass**
+Tests pass once ≠ bulletproof.
+✅ Fix: Continue REFACTOR cycle until no new rationalizations.
+
+## Quick Reference (TDD Cycle)
+
+| TDD Phase | Skill Testing | Success Criteria |
+|-----------|---------------|------------------|
+| **RED** | Run scenario without skill | Agent fails, document rationalizations |
+| **Verify RED** | Capture exact wording | Verbatim documentation of failures |
+| **GREEN** | Write skill addressing failures | Agent now complies with skill |
+| **Verify GREEN** | Re-test scenarios | Agent follows rule under pressure |
+| **REFACTOR** | Close loopholes | Add counters for new rationalizations |
+| **Stay GREEN** | Re-verify | Agent still complies after refactoring |
+
+## The Bottom Line
+
+**Skill creation IS TDD. Same principles, same cycle, same benefits.**
+
+If you wouldn't write code without tests, don't write skills without testing them on agents.
+
+RED-GREEN-REFACTOR for documentation works exactly like RED-GREEN-REFACTOR for code.
+
+## Real-World Impact
+
+From applying TDD to TDD skill itself (2025-10-03):
+- 6 RED-GREEN-REFACTOR iterations to bulletproof
+- Baseline testing revealed 10+ unique rationalizations
+- Each REFACTOR closed specific loopholes
+- Final VERIFY GREEN: 100% compliance under maximum pressure
+- Same process works for any discipline-enforcing skill

-## Architecture decisions and specs
+## Tech Stack
 
-Architectural decisions are documented in `docs/adrs/`. Read these before proposing changes to the areas they cover.
+- **Runtime**: Bun (with `bun test` as the test runner)
+- **Build orchestration**: Nx 22.5 with `@nx/js/typescript` plugin
+- **TypeScript**: 5.9, strict mode, `nodenext` module resolution, `composite` projects
+- **Backend**: Elysia, Drizzle ORM + `postgres.js`, PostgreSQL 16
+- **Validation**: Zod 4
+- **Infrastructure**: Docker Compose (postgres, redis, minio, mailhog)
+- **Custom import condition**: `@mdcms/source` for dev-time source imports
 
-Detailed specifications for each subsystem are in `docs/specs/`. If you're working on a feature, find the relevant spec first. It will save you from going in the wrong direction.
+## Canonical planning docs
+
+- Docs entrypoint: `docs/README.md`
+- Live canonical specs: `docs/specs/README.md`
+- Architecture decisions and rationale: `docs/adrs/README.md`
+- Roadmap and task scope (local-only): `ROADMAP_TASKS.md`
+
+Read these before proposing changes to the areas they cover. The owning spec under `docs/specs/` and the roadmap tasks are the source of truth for scope and acceptance criteria.
+
+## Architecture patterns
+
+**Package boundary rules**: Shared contracts/types go in `@mdcms/shared`. Each app owns its runtime concerns. Avoid circular dependencies between packages.
+
+**Module system**: First-party modules live in `packages/modules/<module-id>/` with a standard structure (`manifest.ts`, `server/index.ts`, `cli/index.ts`). The `installedModules` registry in `packages/modules/src/index.ts` is deterministic and sorted by `manifest.id`. Server and CLI each have their own `module-loader.ts` that mounts module surfaces at startup.
+
+**Exports pattern**: Every package uses conditional exports with `@mdcms/source` pointing to TypeScript source for dev, and `import`/`default` pointing to `dist/` for production.
+
+**Contract tests**: Files named `*.contract.test.ts` validate Drizzle schema against actual SQL migrations. Regular unit tests are `*.test.ts` co-located with source.
+
+**Studio review app sync**: Treat `apps/studio-review` as a maintained repo-internal consumer of Studio and backend contracts. When a change updates any contract that the review app consumes, update the owning spec plus the review app handlers, fixtures, runtime wiring, and tests in the same change so preview mocks stay aligned.
+

+## AI agent infrastructure
+
+The `.ai/` directory at the repo root holds the team's shared AI-agent-facing artifacts. It's a team operating environment, not session state — read it for product knowledge and accumulated learnings, not for "what is someone working on right now" (that's Jira / `ROADMAP_TASKS.md`).
+
+```

+```
+
+**Rules for agents working in this repo:**
+
+1. **Use `.ai/LANGUAGE.md` for naming.** Don't invent synonyms for existing terms.
+2. **Read the relevant `.ai/memory/` file before non-trivial work** — `architecture.md` for invariants, `product.md` for product context, `initiatives/` for whether your work fits an active effort. Volatile state ("what's happening right now") lives in Jira and `ROADMAP_TASKS.md`, not here.
+3. **Append to `.ai/memory/lessons.md` when you hit a non-obvious pitfall.** One short entry; lead with the rule, then `Why:` and `How to apply:` lines.
+4. **Plans live in `.ai/plans/`.** Use the superpowers `writing-plans` and `executing-plans` skills to write and run them. Plans are committed.
+5. **Research goes in `.ai/research/`.** Date-prefixed filename (`YYYY-MM-DD-topic.md`).
+6. **Major efforts get an initiative file** in `.ai/memory/initiatives/` (see that folder's README for the format). Update it on milestones; mark `Status: completed` when wrapping.
+7. **Skills are auto-discovered** by Claude Code, Codex, and Cursor via symlinks (`.claude/skills`, `.agents/skills`, `.cursor/skills` all point to `../.ai/skills`).
+
+The vendored superpowers in `.ai/skills/` is the canonical copy used by every supported agent in this repo. The globally installed `superpowers` plugin is disabled at the project level via `.claude/settings.json` to prevent duplicate skill registration.
+
+**Don't confuse `.ai/skills/` with the top-level `skills/` directory.** They serve opposite audiences:
+
+- `.ai/skills/` — **internal**, dev-time skills for people working ON MDCMS (vendored superpowers).
+- `skills/` (root) — **public**, distributable skills for people USING MDCMS in their own projects (installed via `skills.sh`).
+
+## Task workflow
+
+For any implementation task:
+
+1. Fetch the task from `ROADMAP_TASKS.md` and extract scope, acceptance criteria, and dependencies.
+2. Inspect full context from `docs/specs/README.md`, the owning spec under `docs/specs/`, and `ROADMAP_TASKS.md`, not only the single task block, to understand upstream and downstream constraints. Skim `.ai/memory/architecture.md` for invariants and `.ai/memory/initiatives/` for whether the work fits an active effort.
+3. Map the task to affected packages and files.
+4. Ship only what is in scope for that task.
+5. While implementing in-scope work, shape code so future roadmap tasks fit cleanly and avoid short-term designs that block planned architecture.
+6. Document new public contracts and operator workflows at point of use, including README updates, inline comments, CLI help, and API docs, as required by roadmap acceptance language.
+7. Run validations before finalizing.
+8. If the task touched architecture, the stack, an integration, or an active initiative, update the relevant `.ai/memory/` file in the same change. If you discovered a non-obvious pitfall, append to `.ai/memory/lessons.md`.
+
+If requirements conflict between `ROADMAP_TASKS.md` and the owning spec under `docs/specs/`, call it out explicitly and prefer the stricter interpretation until clarified.
+
+## Spec-first enforcement
+
+For every new implementation request that changes behavior, endpoint contracts, or public interfaces:
+
+1. Verify first that the intended behavior is explicitly specified in the owning spec under `docs/specs/`.
+2. If behavior is missing, ambiguous, or contradictory:
+   - stop implementation,
+   - send a spec-first nudge,
+   - resume only after the spec is updated or confirmed.
+3. Do not treat README notes or inferred code behavior as a substitute for spec.
+4. If roadmap and owning spec conflict, call it out and prefer the stricter interpretation until clarified.
+5. Specs under `docs/specs/` must be standalone product documentation. Do not reference roadmap task IDs, task numbers, `ROADMAP_TASKS.md`, or other external planning context inside spec content. If a spec needs rationale, keep it self-contained or use an ADR.
+
+### Mandatory spec-first nudge template
+
+Use this exact message template whenever scope is not fully specified:
+
+`Spec-first gate: this behavior/endpoint is not fully specified in the owning spec under docs/specs yet. Please update that spec (or confirm exact contract changes) first, then I will implement strictly against that spec delta.`
+
+### Pre-implementation spec coverage checklist
+
+Before writing code, confirm:
+
+1. Endpoint or behavior exists in the owning spec under `docs/specs/`.
+2. Auth mode and required scopes are defined.
+3. Required routing context such as `project` and `environment` is defined where relevant.
+4. Request and success response contracts are defined.
+5. Deterministic error codes and statuses are defined.
+6. CLI and operator workflow notes are defined where applicable.
+
+### Required spec delta summary
+
+For each task, provide a short `spec delta` summary before implementation planning or execution:
+
+1. What changed in the owning spec under `docs/specs/`.
+2. Which endpoint, contract, or behavior is affected.
+3. Which acceptance criteria depend on this spec delta.
+
+### Standalone spec rule
+
+Hard rule:
+
+1. Treat every file under `docs/specs/` as standalone canonical product documentation.
+2. Do not write task identifiers like `CMS-40`, `CMS-79`, or any other roadmap or task references inside specs.
+3. Do not refer to `ROADMAP_TASKS.md`, "this task", or similar planning context inside specs.
+4. If implementation planning context matters, keep it in roadmap files, ADRs, or local plans, not in `docs/specs/`.
+
+## Package boundary rules
+
+- Keep shared contracts and cross-cutting types in `@mdcms/shared`.
+- Keep CLI concerns in `@mdcms/cli`.
+- Keep SDK consumer-facing client logic in `@mdcms/sdk`.
+- Keep Studio embedding and runtime-loader concerns in `@mdcms/studio`.
+- Keep backend runtime and API concerns in `@mdcms/server`.
+
+When moving code across packages, preserve clear ownership and avoid circular dependencies.
+
+## Contract and compatibility rules
+
+- Keep TypeScript module settings aligned with existing workspace config such as `nodenext` and project references.
+- Keep package export conventions intact unless the task requires change.
+- Treat `apps/studio-review` as a maintained repo-internal compatibility consumer of Studio and backend contracts. If a change affects any contract consumed by the review app, update the owning spec, the review app handlers, fixtures, runtime wiring, and the relevant review tests in the same change so preview mocks do not drift.
+
+Any new public API surface must include minimal usage docs and, where applicable, typed contracts.
+
+## Linting and formatting policy
+
+- Prettier is enabled and should be used.
+- Do not add or require lint targets or config unless the active task explicitly includes lint baseline work.
+
+## Commit and change hygiene
+
+- Make focused, task-scoped commits.
+- Don't include unrelated local folders or tooling artifacts. `.gitignore` enforces what stays local.
+- Follow conventional commit message format: `type(scope): message`.
+
+Before commit, ensure:
+
+1. `bun run format:check` passes.
+2. `bun run check` passes.
+3. Task-specific verification steps from `ROADMAP_TASKS.md` are satisfied.

Subject: [PATCH 2/7] chore(ai-harness): fix factual errors and stale
 references in memory docs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up to the harness pilot, addressing issues caught in review:

- `schema sync` (with space) is the actual CLI command name, not
  `schema-sync` (hyphen). Fixed in `apps/cli/AGENTS.md` and
  `.ai/memory/topics/push-pull-sync.md`.
- Removed `TanStack Router` from `.ai/memory/stack.md` — it's not in
  any package.json. Fabricated.
- Removed stale `Jira` mention from `.ai/memory/README.md`'s
  integrations index; the file was deliberately not committed
  (refers to user-local Jira/MCP setup).
- Dropped pre-push-hook claims in `AGENTS.md`,
  `.ai/memory/stack.md`, and `.ai/memory/integrations/github-actions.md`
  — no such hook is configured. Reframed as a manual local step.
- Tightened `.ai/memory/topics/multi-tenancy.md` "Storage layer"
  bullets to match the softened "tenant-scoped" framing already
  in the file's intro paragraph (auth tables don't carry `project_id`).

Subject: [PATCH 3/7] chore(ai-harness): start .ai/plans/ blank instead of
 seeding history
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The first commit on this branch backfilled 76 plan files from the
local-only `docs/plans/` working directory into `.ai/plans/`. On
review that's mostly redundant with `docs/specs/`, `docs/adrs/`, and
the merged PR history — execution plans for already-shipped CMS-NN
tickets don't add durable team knowledge that the canonical docs
don't already capture.

Drop the 76 historical plans from the PR. The directory survives via
`.gitkeep` so the convention is in place, and new plans created by
the `writing-plans` skill going forward will be tracked normally.

Local copies of the historical plans remain untouched in the working
tree — anyone who wants to fold a specific plan's reasoning into an
ADR or `.ai/research/` artifact can still do so.

Updates AGENTS.md's `.ai/plans/` description from "historical record"
to "populated as new work happens" to reflect the new framing.

-# CMS-16 Environment Overlay Resolver Design
-
-## Scope
-
-Implement the shared resolver foundation for environment-specific schema overlays in `mdcms.config.ts`.
-
-This design is intentionally limited to resolver behavior in shared config parsing and CLI config loading. It does not add schema registry endpoints or thread resolved schemas into server content read/write paths yet.
-
-## Spec Delta
-
-- No `SPEC.md` change is required for this design.
-- This work implements the existing spec and roadmap contract for:
-  - environment overlays via `add`, `modify`, and `omit`
-  - field-level `.env()` sugar
-  - environment inheritance via `extends`
-
-## Goals
-
-- Produce deterministic resolved schemas per environment.
-- Preserve the current package boundaries by keeping the authoring and resolver contract in `@mdcms/shared`.
-- Keep the output shape reusable for `CMS-17` schema sync and later server-side validation consumers.
-- Fail invalid authoring configurations with actionable `INVALID_CONFIG` errors.
-
-## Non-Goals
-
-- No schema registry persistence or hash endpoints.
-- No server runtime consumption of resolved schemas yet.
-- No changes to content API behavior in this task.
-
-## Authoring Contract
-
-### Base Types
-
-`defineType(name, definition)` continues to define the base type shared across environments.
-
-### Overlay Authoring
-
-Each type definition exposes `.extend(...)` for environment-local overlays:
-
-```ts
-const blogPost = defineType("BlogPost", {
-  directory: "content/blog",
-  localized: true,
-  fields: {
-    title: z.string().min(1).max(200),
-    slug: z.string().regex(/^[a-z0-9-]+$/),
-    author: reference("Author"),
-    tags: z.array(z.string()).default([]),
-    featured: z.boolean().default(false).env("staging", "preview"),
-    abTestVariant: z.enum(["control", "a", "b"]).optional().env("preview"),
-  },
-});
-
-export default defineConfig({
-  project: "marketing-site",
-  serverUrl: "http://localhost:4000",
-  contentDirectories: ["content"],
-  types: [blogPost],
-  locales: {
-    default: "en-US",
-    supported: ["en-US", "fr"],
-  },
-  environments: {
-    production: {},
-    staging: {
-      extends: "production",
-      types: {
-        BlogPost: blogPost.extend({
-          modify: {
-            tags: z.array(z.string()).min(1),
-          },
-        }),
-      },
-    },
-    preview: {
-      extends: "staging",
-      types: {
-        BlogPost: blogPost.extend({
-          add: {
-            reviewerNotes: z.string().optional(),
-          },
-          omit: ["slug"],
-        }),
-      },
-    },
-  },
-});
-```
-
-## Resolver Model
-
-The resolver runs in three phases inside the shared config contract.
-
-### 1. Parse Authoring Input
-
-- Parse base config fields as in `CMS-15`.
-- Parse type definitions and Standard Schema-compatible fields.
-- Parse environment overlay definitions:
-  - `extends?: string`
-  - `types?: Record<string, ParsedTypeOverlay>`
-- Attach MDCMS metadata for:
-  - reference fields
-  - `.env()` sugar targets
-
-### 2. Normalize Overlay Sources
-
-- Convert explicit `extend({ add, modify, omit })` payloads into a normalized internal overlay shape.
-- Expand field-level `.env(...targets)` metadata into synthetic environment `add` overlays for the owning type.
-- Reject conflicts where the same environment/type/field is introduced both by sugar expansion and explicit overlay input.
-
-### 3. Resolve Environments
-
-- Resolve each environment independently but deterministically.
-- Apply inheritance parent-first, then child overlay.
-- Each environment level contributes only its incremental changes.
-- The resolved output includes fully materialized per-environment type definitions and field maps in stable order.
-
-## Deterministic Rules
-
-- Base type fields are the source schema for environments with no overlays.
-- `.env()` fields do not exist in the base resolved field set. They are only added to the targeted environments.
-- `extends` chains resolve from ancestor to descendant.
-- `add` may only introduce a field that does not yet exist in the inherited schema at that resolution point.
-- `modify` may only target a field that already exists in the inherited schema at that resolution point.
-- `omit` may only remove a field that already exists in the inherited schema at that resolution point.
-- Environment names, type names, overlay maps, and resolved field names are sorted before output to make hashing and snapshots deterministic.
-
-## Error Handling
-
-All authoring failures are surfaced as `RuntimeError` with `code: "INVALID_CONFIG"`.
-
-### Environment Graph Errors
-
-- unknown `extends` target
-- self-referential `extends`
-- circular inheritance chains
-
-Error messages must include the environment name and, for cycles, the full discovered chain.
-
-### Overlay Target Errors
-
-- overlay references an unknown type
-- `add` targets an already-present field
-- `modify` targets a missing field
-- `omit` targets a missing field
-
-Error messages must include environment, type, and field context.
-
-### Sugar Conflicts
-
-- `.env()` expansion and explicit overlay both try to define the same added field for the same environment/type
-
-The diagnostic must direct the user to keep one source of truth.
-
-## Public Output Shape
-
-`parseMdcmsConfig(...)` should continue to return the normalized base config and also expose deterministic resolved environment output for downstream tasks.
-
-Expected additions:
-
-- parsed `environments` definitions
-- `resolvedEnvironments` map keyed by environment name
-- resolved type definitions that preserve:
-  - name
-  - directory
-  - localized
-  - resolved `fields`
-  - resolved `referenceFields`
-
-This keeps `CMS-17` from needing to re-implement overlay resolution.
-
-## Documentation
-
-Point-of-use docs should be updated in:
-
-- `packages/shared/README.md`
-- `apps/cli/README.md`
-
-Documentation should explain:
-
-- how `extends` works
-- when to use `add` vs `modify` vs `omit`
-- how `.env()` expands
-- that this task only defines resolver behavior, with server consumption deferred to later tasks
-
-## Testing
-
-### Shared Unit Tests
-
-Expand `packages/shared/src/lib/contracts/config.test.ts` with:
-
-- deterministic per-environment resolution
-- multi-hop inheritance resolution
-- `.env()` sugar expansion
-- sugar vs explicit overlay conflict rejection
-- missing parent rejection
-- self-cycle rejection
-- multi-node cycle rejection
-- invalid `add`
-- invalid `modify`
-- invalid `omit`
-
-### CLI Coverage
-
-Extend `apps/cli/src/lib/config.test.ts` to prove CLI config loading returns the new resolved environment output unchanged from the shared parser.
-
-## Implementation Notes
-
-- Keep the resolver library-agnostic at the public boundary by continuing to accept Standard Schema-compatible field validators.
-- Use schema metadata rather than introducing server-only coupling.
-- Do not thread resolved schemas into server content APIs in this task.

-# CMS-16 Environment Overlay Resolver Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Implement deterministic environment overlay resolution for `mdcms.config.ts`, including `add` / `modify` / `omit`, `.env()` sugar, and `extends` inheritance, without wiring resolved schemas into server content APIs yet.
-
-**Architecture:** Extend the shared config contract in `@mdcms/shared` so base type definitions, environment overlays, and field metadata are parsed and normalized in one place. Resolve overlays parent-first into stable per-environment type maps, then expose that output through the existing CLI config loader so later schema-sync tasks can consume a canonical resolved snapshot.
-
-**Tech Stack:** TypeScript, Bun test runner, Zod 4 metadata, Nx monorepo package boundaries
-
----
-
-### Task 1: Add Shared Overlay Authoring Surface
-
-**Files:**
-
-- Modify: `packages/shared/src/lib/contracts/config.ts`
-- Test: `packages/shared/src/lib/contracts/config.test.ts`
-
-**Step 1: Write the failing test**
-
-Add a shared config test that authors environment overlays with `.extend({ add, modify, omit })` and asserts `parseMdcmsConfig(...)` returns parsed environment metadata plus deterministic `resolvedEnvironments`.
-
-```ts
-test("parseMdcmsConfig resolves environment overlays and env sugar deterministically", () => {
-  const blogPost = defineType("BlogPost", {
-    directory: "content/blog",
-    localized: true,
-    fields: {
-      title: z.string(),
-      slug: z.string(),
-      tags: z.array(z.string()).default([]),
-      featured: z.boolean().default(false).env("staging", "preview"),
-    },
-  });
-
-  const parsed = parseMdcmsConfig(
-    defineConfig({
-      project: "marketing-site",
-      serverUrl: "http://localhost:4000",
-      contentDirectories: ["content"],
-      locales: { default: "en-US", supported: ["en-US"] },
-      types: [blogPost],
-      environments: {
-        production: {},
-        staging: {
-          extends: "production",
-          types: {
-            BlogPost: blogPost.extend({
-              modify: {
-                tags: z.array(z.string()).min(1),
-              },
-            }),
-          },
-        },
-      },
-    }),
-  );
-
-  assert.deepEqual(Object.keys(parsed.resolvedEnvironments), [
-    "production",
-    "staging",
-  ]);
-  assert.equal(
-    parsed.resolvedEnvironments.staging.types.BlogPost.fields.featured !==
-      undefined,
-    true,
-  );
-});
-```
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test packages/shared/src/lib/contracts/config.test.ts`
-Expected: FAIL because `defineType(...).extend`, `.env(...)`, `environments`, or `resolvedEnvironments` do not exist yet.
-
-**Step 3: Write minimal implementation**
-
-In `packages/shared/src/lib/contracts/config.ts`:
-
-- add authoring types for environment overlays
-- update `defineType(...)` to return an object with `.extend(...)`
-- add metadata helpers for `.env(...)`
-- parse `config.environments`
-- add parsed/resolved config output types
-
-Representative structure:
-
-```ts
-export type MdcmsTypeOverlay = {
-  add?: Record<string, MdcmsFieldSchema>;
-  modify?: Record<string, MdcmsFieldSchema>;
-  omit?: string[];
-};
-
-export type MdcmsEnvironmentDefinition = {
-  extends?: string;
-  types?: Record<string, MdcmsTypeOverlay>;
-};
-
-export type ParsedResolvedEnvironment = {
-  types: Record<string, ParsedMdcmsTypeDefinition>;
-};
-
-function createTypeDefinition<
-  TName extends string,
-  TFields extends Record<string, MdcmsFieldSchema>,
->(
-  name: TName,
-  definition: {
-    directory?: string;
-    localized?: boolean;
-    fields: TFields;
-  },
-): MdcmsTypeDefinition<TName, TFields> {
-  return {
-    name,
-    ...definition,
-    extend(overlay) {
-      return overlay;
-    },
-  };
-}
-```
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test packages/shared/src/lib/contracts/config.test.ts`
-Expected: PASS for the new resolution-path test, even if later failure-path tests are still missing.
-
-**Step 5: Commit**
-
-```bash
-git add packages/shared/src/lib/contracts/config.ts packages/shared/src/lib/contracts/config.test.ts
-git commit -m "feat(shared): add environment overlay config surface"
-```
-
-### Task 2: Implement Resolver Validation and Error Paths
-
-**Files:**
-
-- Modify: `packages/shared/src/lib/contracts/config.ts`
-- Test: `packages/shared/src/lib/contracts/config.test.ts`
-
-**Step 1: Write the failing tests**
-
-Add targeted tests for:
-
-- missing `extends` target
-- self-cycle
-- multi-node cycle
-- `.env()` plus explicit `add` conflict
-- invalid `add`
-- invalid `modify`
-- invalid `omit`
-
-Example failure test:
-
-```ts
-test("parseMdcmsConfig rejects circular extends chains", () => {
-  assert.throws(
-    () =>
-      parseMdcmsConfig(
-        defineConfig({
-          project: "marketing-site",

-          types: [defineType("Page", { fields: { title: z.string() } })],
-          environments: {
-            staging: { extends: "preview" },
-            preview: { extends: "staging" },
-          },
-        }),
-      ),
-    (error: unknown) =>
-      error instanceof RuntimeError &&
-      error.code === "INVALID_CONFIG" &&
-      error.message.includes("staging") &&
-      error.message.includes("preview"),
-  );
-});
-```
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test packages/shared/src/lib/contracts/config.test.ts`
-Expected: FAIL because cycles/conflicts are not yet rejected with stable diagnostics.
-
-**Step 3: Write minimal implementation**
-
-Add resolver helpers in `packages/shared/src/lib/contracts/config.ts`:
-
-- `parseEnvironments(...)`
-- `extractEnvFieldTargets(...)`
-- `expandEnvSugar(...)`
-- `resolveEnvironmentChain(...)`
-- `applyTypeOverlay(...)`
-
-Representative core logic:
-
-```ts
-function applyTypeOverlay(
-  typeConfig: ParsedMdcmsTypeDefinition,
-  overlay: ParsedTypeOverlay,
-  context: { environment: string; typeName: string },
-): ParsedMdcmsTypeDefinition {
-  const fields = { ...typeConfig.fields };
-
-  for (const [fieldName, schema] of Object.entries(overlay.add)) {
-    if (fieldName in fields) {
-      throw invalidConfig(
-        `environments.${context.environment}.types.${context.typeName}.add.${fieldName}`,
-        "cannot add a field that already exists in the inherited schema.",
-      );
-    }
-    fields[fieldName] = schema;
-  }
-
-  for (const [fieldName, schema] of Object.entries(overlay.modify)) {

-}
-```
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test packages/shared/src/lib/contracts/config.test.ts`
-Expected: PASS for overlay matrix and failure diagnostics.
-
-**Step 5: Commit**
-
-```bash
-git add packages/shared/src/lib/contracts/config.ts packages/shared/src/lib/contracts/config.test.ts

-- Modify: `packages/shared/README.md`
-- Modify: `apps/cli/README.md`
-
-**Step 1: Write the failing test**
-
-Extend the CLI config loader test to assert `loadCliConfig(...)` exposes the resolved environment output.
-
-```ts
-test("loadCliConfig returns resolved environment schemas from the shared parser", async () => {
-  const { cwd } = await writeConfigFile(`
-    import { defineConfig, defineType } from "@mdcms/cli";

-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test apps/cli/src/lib/config.test.ts`

-
-**Step 3: Write minimal implementation**
-
-- update `CliConfig` in `apps/cli/src/lib/config.ts` to include parsed `environments` and `resolvedEnvironments`
-- keep `loadCliConfig(...)` delegating to `parseMdcmsConfig(...)`

-
-Representative type update:

-# CMS-17 Schema Registry Endpoints Design
-
-## Scope
-
-Implement the schema registry foundation for:
-
-- `GET /api/v1/schema`
-- `GET /api/v1/schema/:type`
-- `PUT /api/v1/schema`
-
-This task covers registry persistence, read/write API contracts, hash tracking,
-and deterministic error handling for raw and resolved schema snapshots.
-
-## Spec Delta
-
-`SPEC.md` already defines the route surface, auth scopes, target routing, and
-the top-level `PUT /api/v1/schema` success envelope. This design defines the
-missing contract details that must be reflected in `SPEC.md` before or alongside
-implementation:
-
-- `SchemaRegistryEntry` response shape
-- registry storage model
-- descriptive snapshot limitations
-- deterministic `INVALID_INPUT` vs `SCHEMA_INCOMPATIBLE` semantics
-
-## Goals
-
-- Persist the latest schema sync state per `(project, environment)`.
-- Return one registry entry per schema type for the target environment.
-- Support stable hash comparison and sync metadata reads.
-- Fail unsupported or unserializable schema features deterministically.
-- Reserve `409 SCHEMA_INCOMPATIBLE` for migration-requiring schema conflicts
-  rather than malformed payloads.
-
-## Non-Goals
-
-- No schema sync history beyond the latest state per target environment.
-- No exact reconstruction of executable Zod or Standard Schema validators.
-- No content migration execution in this task.
-- No Studio schema editing UI.
-
-## Chosen Model
-
-### Registry Read Model
-
-The registry is type-centric.
-
-- `GET /api/v1/schema` returns one `SchemaRegistryEntry` per type for the target
-  `(project, environment)`.
-- `GET /api/v1/schema/:type` returns a single `SchemaRegistryEntry`.
-- `PUT /api/v1/schema` writes environment-level sync metadata and derives the
-  per-type registry rows from the uploaded resolved schema snapshot.
-
-### Sync History
-
-Sync history is out of scope for `CMS-17`.
-
-The registry stores only the latest sync state per `(project, environment)`.
-Current spec and roadmap text require read/write registry behavior and hash
-comparison, but do not require historical sync records.
-
-## Snapshot Fidelity
-
-The schema registry stores descriptive JSON snapshots, not executable validator
-objects.
-
-This is an explicit limitation of `CMS-17`.
-
-- Stored schema data is suitable for:
-  - hash comparison
-  - schema mismatch detection
-  - read-only Studio schema display
-  - future introspection based on descriptive metadata
-- Stored schema data is not suitable for exact reconstruction of runtime
-  validator behavior.
-
-### Unsupported Features
-
-The registry must reject schema payloads that depend on executable or otherwise
-unserializable behavior that cannot be represented losslessly in the descriptive
-snapshot model.
-
-Examples include:
-
-- `.refine()`
-- `.superRefine()`
-- `transform`
-- `preprocess`
-- arbitrary functions
-- non-JSON values
-- any custom validator behavior that cannot be preserved in the registry JSON
-
-These failures are `INVALID_INPUT` (`400`), not compatibility conflicts.
-
-## Public API Contract
-
-### PUT `/api/v1/schema`
-
-Request body:
-
-```ts
-{
-  rawConfigSnapshot: Record<string, unknown>;
-  resolvedSchema: Record<string, Record<string, unknown>>;
-  schemaHash: string;
-  extractedComponents?: unknown;
-}
-```
-
-Behavior:
-
-- validates the request body shape
-- validates that the payload can be represented by the descriptive registry
-  model
-- validates compatibility against the currently stored registry and current
-  content rows
-- upserts the environment-level sync row
-- replaces the environment's derived per-type registry rows in a single
-  transaction
-
-Success response:
-
-```ts
-{
-  data: {
-    schemaHash: string;
-    syncedAt: string;
-    affectedTypes: string[];
-  };
-}
-```
-
-### GET `/api/v1/schema`
-
-Success response:
-
-```ts
-{
-  data: SchemaRegistryEntry[];
-}
-```
-
-### GET `/api/v1/schema/:type`
-
-Success response:
-
-```ts
-{
-  data: SchemaRegistryEntry;
-}
-```
-
-### SchemaRegistryEntry
-
-```ts
-type SchemaRegistryEntry = {
-  type: string;
-  directory: string;
-  localized: boolean;
-  schemaHash: string;
-  syncedAt: string;
-  resolvedSchema: Record<string, unknown>;
-};
-```
-
-Notes:
-
-- `schemaHash` and `syncedAt` are duplicated across entries for a given target
-  environment. This keeps the current route contract simple without introducing
-  a new top-level metadata envelope.
-- `rawConfigSnapshot` is stored at the environment sync level and is not
-  returned by `GET` endpoints.
-
-## Storage Model
-
-Use two tables.
-
-### 1. Environment-Level Sync Table
-
-One row per `(project_id, environment_id)`.
-
-Suggested shape:
-
-```ts
-schema_syncs = {
-  id: uuid,
-  projectId: uuid,
-  environmentId: uuid,
-  schemaHash: text,
-  rawConfigSnapshot: jsonb,
-  extractedComponents: jsonb | null,
-  syncedAt: timestamptz,
-};
-```
-
-Constraints and indexing:
-
-- unique on `(project_id, environment_id)`
-- composite foreign key to `(environments.id, environments.project_id)`
-- scope index on `(project_id, environment_id)`
-
-### 2. Per-Type Registry Table
-
-One row per `(project_id, environment_id, schema_type)`.
-
-Suggested shape:
-
-```ts
-schema_registry_entries = {
-  id: uuid,
-  projectId: uuid,
-  environmentId: uuid,
-  schemaType: text,
-  directory: text,
-  localized: boolean,
-  schemaHash: text,
-  resolvedSchema: jsonb,
-  syncedAt: timestamptz,
-};
-```
-
-Constraints and indexing:
-
-- unique on `(project_id, environment_id, schema_type)`
-- composite foreign key to `(environments.id, environments.project_id)`
-- scope index on `(project_id, environment_id, schema_type)`
-
-## Validation and Errors
-
-### `400 INVALID_INPUT`
-
-Used when the request is malformed or the registry cannot preserve the uploaded
-schema payload in its descriptive snapshot model.
-
-Examples:
-
-- missing or malformed top-level request fields
-- `resolvedSchema` is not a type map
-- a type entry is missing required descriptive fields
-- unsupported or unserializable validator features
-- non-JSON values
-
-Diagnostics must be actionable and point to the failing type/field/path when
-possible.
-
-### `409 SCHEMA_INCOMPATIBLE`
-
-Used only when the payload is valid and serializable, but applying it would
-conflict with existing content and should require a migration first.
-
-For `CMS-17`, compatibility checks stay structural and coarse-grained.
-
-Examples:
-
-- removing a type that still has documents in the target environment
-- changing localization mode in a way that conflicts with existing documents
-- removing a supported locale that still has documents
-- making a previously optional or absent field required for a type that already
-  has documents
-- changing a field's coarse kind in a clearly breaking way for existing content
-  such as:
-  - scalar to array
-  - array to scalar
-  - object to scalar
-  - reference target `Author` to `Category`
-
-Anything the registry cannot structurally reason about stays out of `409` and is
-either accepted or rejected as `400` depending on serializability.
-
-## Authorization and Routing
-
-- `/api/v1/schema*` remains explicitly scoped by `(project, environment)` via
-  the existing target routing guard.
-- `GET` routes require `schema:read`.
-- `PUT` requires `schema:write`.
-- Session-based RBAC mapping must be extended so privileged Studio users are
-  actually constrained by the schema scopes already defined for API keys.
-
-## Server Architecture
-
-Add a dedicated schema API module:
-
-- `apps/server/src/lib/schema-api.ts`
-
-Responsibilities:
-
-- request parsing and validation
-- route mounting
-- compatibility checks
-- DB-backed registry store
-- API response shaping
-
-Mount it from the shared server bootstrap alongside auth, content, and
-collaboration routes.
-
-Shared request/response contracts should live in:
-
-- `packages/shared/src/lib/contracts/schema.ts`
-
-## Persistence Rules
-
-- schema sync never mutates content rows
-- `PUT /api/v1/schema` replaces only registry state for the target environment
-- all writes happen transactionally:
-  - upsert environment sync row
-  - delete stale type rows for the target environment
-  - insert replacement type rows
-
-## Documentation
-
-Point-of-use docs should be updated in:
-
-- `SPEC.md`
-- `apps/cli/README.md`
-- `packages/shared/README.md`
-
-The docs must explicitly call out:
-
-- the descriptive snapshot limitation
-- unsupported validator features
-- the `400` vs `409` error split
-- that schema sync updates the registry only and does not mutate content rows
-
-## Testing
-
-### Shared Contract Tests
-
-Add shared tests for:
-
-- request and response shape validation
-- serializer rejection of unsupported features
-- deterministic hash and entry ordering behavior where applicable
-
-### Server API Contract Tests
-
-Add endpoint tests covering:
-
-- `GET /schema` success
-- `GET /schema/:type` success
-- `GET /schema/:type` not found
-- `PUT /schema` success
-- `PUT /schema` malformed request -> `400`
-- `PUT /schema` unsupported/unserializable schema -> `400`
-- `PUT /schema` compatibility conflict -> `409`
-- explicit target routing enforcement
-- auth scope enforcement for both API keys and sessions
-
-### Database Contract Tests
-
-Add DB contract coverage for:
-
-- new schema registry tables
-- unique constraints
-- composite environment/project foreign keys
-- scope indexes
-
-## Implementation Notes
-
-- The server should treat uploaded schema payloads as descriptive data, not as a
-  source of executable validators.
-- The serializer contract should be strict and fail closed when it encounters
-  unsupported features.
-- Compatibility checks should stay minimal, deterministic, and structural in
-  `CMS-17`.

-# CMS-17 Schema Registry Endpoints Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Implement `/api/v1/schema`, `/api/v1/schema/:type`, and `PUT /api/v1/schema` with latest-state registry persistence, schema hash tracking, deterministic `400` vs `409` behavior, and target-scoped auth/routing.
-
-**Architecture:** Add a new shared schema contract layer for registry payload validation and descriptive snapshot serialization, persist latest sync metadata plus derived per-type rows in new server DB tables, and expose a dedicated server route module wired alongside auth/content routes. Keep the registry descriptive only: unsupported executable validator features fail closed with `INVALID_INPUT`, while coarse migration-requiring conflicts return `SCHEMA_INCOMPATIBLE`.
-
-**Tech Stack:** Bun, Nx, TypeScript, Drizzle ORM/Postgres, Elysia, shared `RuntimeError` envelopes, existing target-routing/auth infrastructure.
-
----
-
-### Task 0: Lock The Approved Spec Delta Locally
-
-**Files:**
-
-- Modify: `SPEC.md` (local-only, do not stage/commit)
-- Reference: `docs/plans/2026-03-11-cms-17-design.md`
-
-**Step 1: Add the missing schema registry contract details to the local spec**
-
-Add the approved details from the design doc:
-
-- `SchemaRegistryEntry` shape
-- latest-state registry model
-- descriptive snapshot limitation
-- unsupported feature rejection semantics
-- `INVALID_INPUT` vs `SCHEMA_INCOMPATIBLE`
-
-**Step 2: Verify the local spec contains the approved contract**
-
-Run: `rg -n "SchemaRegistryEntry|SCHEMA_INCOMPATIBLE|descriptive snapshot|unsupported" SPEC.md`
-
-Expected: matching lines for the new schema registry contract language.
-
-**Step 3: Confirm the spec file remains unstaged**
-
-Run: `git status --short`
-
-Expected: `SPEC.md` remains untracked or unstaged per repo rules.
-
-### Task 1: Add Shared Schema Registry Contracts And Serializer Guards
-
-**Files:**
-
-- Create: `packages/shared/src/lib/contracts/schema.ts`
-- Create: `packages/shared/src/lib/contracts/schema.test.ts`
-- Modify: `packages/shared/src/index.ts`
-
-**Step 1: Write failing shared tests for the public schema registry contract**
-
-Cover:
-
-- `SchemaRegistryEntry` validation
-- `PUT /schema` request payload validation
-- serializer rejection of unsupported features
-- deterministic `INVALID_INPUT` diagnostics for unsupported/unserializable paths
-
-**Step 2: Run the new shared contract test to verify it fails**
-
-Run: `bun test packages/shared/src/lib/contracts/schema.test.ts`
-
-Expected: FAIL because the shared schema registry contract does not exist yet.
-
-**Step 3: Implement the minimal shared contract surface**
-
-In `schema.ts` add:
-
-- JSON-ish value helpers/types for registry payloads
-- validators/parsers for:
-  - schema sync request body
-  - schema registry entry
-  - optional extracted components payload
-- descriptive snapshot serializer guards that reject unsupported features with
-  actionable `RuntimeError({ code: "INVALID_INPUT" })`
-
-**Step 4: Export the new shared contract**
-
-Update `packages/shared/src/index.ts` to export `./lib/contracts/schema.js`.
-
-**Step 5: Re-run the shared contract test**
-
-Run: `bun test packages/shared/src/lib/contracts/schema.test.ts`
-
-Expected: PASS.
-
-**Step 6: Typecheck shared**
-
-Run: `bun x tsc -p packages/shared/tsconfig.lib.json --noEmit`
-
-Expected: PASS.
-
-**Step 7: Commit**
-
-```bash
-git add packages/shared/src/lib/contracts/schema.ts packages/shared/src/lib/contracts/schema.test.ts packages/shared/src/index.ts
-git commit -m "feat(shared): add schema registry contracts"
-```
-
-### Task 2: Add Schema Registry Tables, Migration, And DB Contract Coverage
-
-**Files:**
-
-- Modify: `apps/server/src/lib/db/schema.ts`
-- Modify: `apps/server/src/lib/db/schema.contract.test.ts`
-- Create: `apps/server/drizzle/0007_<name>.sql`
-- Modify: `apps/server/drizzle/meta/_journal.json`
-- Create or Modify: `apps/server/drizzle/meta/0007_snapshot.json`
-
-**Step 1: Extend the DB contract test with failing expectations**
-
-Add assertions for:
-
-- `schema_syncs` columns, uniques, FK, indexes
-- `schema_registry_entries` columns, uniques, FK, indexes
-
-**Step 2: Run the DB contract test to verify it fails**
-
-Run: `bun test apps/server/src/lib/db/schema.contract.test.ts`
-
-Expected: FAIL because the new tables/migration artifacts do not exist.
-
-**Step 3: Add the new Drizzle table definitions**
-
-In `schema.ts`, add:
-
-- `schemaSyncs`
-- `schemaRegistryEntries`
-
-Follow the existing environment-scoped pattern:
-
-- `projectId`
-- `environmentId`
-- composite FK back to `environments`
-- unique constraints for latest sync row and per-type row uniqueness
-
-**Step 4: Add the new migration artifacts**
-
-Create the next migration after `0006_concerned_logan.sql` and update the
-journal/meta snapshot so the contract test sees the new schema.
-
-**Step 5: Re-run the DB contract test**
-
-Run: `bun test apps/server/src/lib/db/schema.contract.test.ts`
-
-Expected: PASS.
-
-**Step 6: Typecheck server DB code**
-
-Run: `bun x tsc -p apps/server/tsconfig.lib.json --noEmit`
-
-Expected: PASS.
-
-**Step 7: Commit**
-
-```bash
-git add apps/server/src/lib/db/schema.ts apps/server/src/lib/db/schema.contract.test.ts apps/server/drizzle
-git commit -m "feat(server): add schema registry tables"
-```
-
-### Task 3: Add Registry Persistence And Compatibility Logic
-
-**Files:**
-
-- Create: `apps/server/src/lib/schema-api.ts`
-- Create: `apps/server/src/lib/schema-api.test.ts`
-- Reference: `apps/server/src/lib/content-api.ts`
-
-**Step 1: Write failing schema API/store tests for the core success path**
-
-Cover:
-
-- `PUT /api/v1/schema` persists one sync row plus derived type rows
-- `GET /api/v1/schema` returns one entry per type
-- `GET /api/v1/schema/:type` returns the correct type
-
-Use the same testing style as `content-api.test.ts`.
-
-**Step 2: Run the new server test to verify it fails**
-
-Run: `bun test apps/server/src/lib/schema-api.test.ts`
-
-Expected: FAIL because the route module/store does not exist yet.
-
-**Step 3: Implement the registry store and route module**
-
-In `schema-api.ts`:
-
-- add a DB-backed registry store abstraction
-- parse target scope from request
-- validate `PUT` request payload with the shared contract
-- transactionally:
-  - resolve scope ids without auto-creating project/environment
-  - upsert the environment-level sync row
-  - replace derived per-type rows for that environment
-- shape success responses as `{ data: ... }`
-
-**Step 4: Implement structural compatibility checks**
-
-Still in `schema-api.ts`, add compatibility logic for `409 SCHEMA_INCOMPATIBLE`
-covering the approved coarse rules:
-
-- deleting a type that still has documents
-- incompatible localization changes
-- removing a supported locale that still has documents
-- introducing required fields against existing documents
-- clearly breaking coarse field-kind changes
-
-Keep anything unsupported or unserializable in the `400 INVALID_INPUT` path.
-
-**Step 5: Re-run the schema API test**
-
-Run: `bun test apps/server/src/lib/schema-api.test.ts`
-
-Expected: PASS for the initial success-path and compatibility coverage.
-
-**Step 6: Commit**
-
-```bash
-git add apps/server/src/lib/schema-api.ts apps/server/src/lib/schema-api.test.ts
-git commit -m "feat(server): add schema registry API"

-- Modify: `apps/server/src/lib/auth.test.ts`
-- Modify: `apps/server/src/lib/target-routing-guard.test.ts`
-
-**Step 1: Add failing auth/routing tests**
-
-Cover:
-
-- missing target routing for `/api/v1/schema`
-- mismatched target routing
-- API key `schema:read` required for `GET`
-- API key `schema:write` required for `PUT`
-- session-based RBAC gating for schema routes
-
-**Step 2: Run the affected auth/routing tests to verify they fail**
-
-Run:
-
-- `bun test apps/server/src/lib/auth.test.ts`
-- `bun test apps/server/src/lib/target-routing-guard.test.ts`
-
-Expected: FAIL because schema routes are not yet mounted into auth coverage or
-RBAC action mapping.
-
-**Step 3: Extend RBAC action mapping for schema routes**
-
-Update `rbac.ts` and `auth.ts` so sessions can be authorized for:
-
-- `schema:read`
-- `schema:write`
-
-Preserve deny-by-default behavior.
-
-**Step 4: Mount the schema API routes in server bootstrap**
-
-Update `runtime-with-modules.ts` to mount the new schema route module with the
-same `authorizeRequest` surface used by content routes.
-
-**Step 5: Re-run auth and routing tests**
-
-Run:
-
-- `bun test apps/server/src/lib/auth.test.ts`
-- `bun test apps/server/src/lib/target-routing-guard.test.ts`
-
-Expected: PASS.
-
-**Step 6: Commit**
-
-```bash
-git add apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/auth.ts apps/server/src/lib/rbac.ts apps/server/src/lib/auth.test.ts apps/server/src/lib/target-routing-guard.test.ts

-
-- Modify: `packages/shared/README.md`
-- Modify: `apps/cli/README.md`
-- Modify: `apps/server/src/lib/schema-api.ts`
-
-**Step 1: Add or update point-of-use documentation**
-
-Document:
-
-- schema registry endpoint behavior
-- latest-state sync model
-- descriptive snapshot limitation
-- unsupported feature rejection
-- `400 INVALID_INPUT` vs `409 SCHEMA_INCOMPATIBLE`
-- registry-only writes during schema sync
-
-Add short code comments in `schema-api.ts` for non-obvious compatibility and
-serialization logic.
-
-**Step 2: Format the changed docs/source files**
-
-Run: `bun x prettier --write packages/shared/README.md apps/cli/README.md apps/server/src/lib/schema-api.ts`
-
-Expected: files rewritten or confirmed already formatted.
-
-**Step 3: Commit**
-
-```bash
-git add packages/shared/README.md apps/cli/README.md apps/server/src/lib/schema-api.ts
-git commit -m "docs: describe schema registry limits"

-# CMS-19 Project Boundaries Design
-
-## Scope
-
-Implement CMS-19 strictly within the existing server/runtime surface:
-
-- keep project identity backed by `projects.slug`
-- preserve nullable `organization_id`
-- centralize project/environment scope resolution for server stores
-- prove cross-project isolation for content, schema, and environment operations
-
-Out of scope:
-
-- project CRUD endpoints
-- auth or RBAC behavior changes
-- Studio project switcher work
-- new media or webhook runtime APIs
-
-## Approved Approach
-
-Use an internal repository-style refactor, not a public API expansion.
-
-The existing project/environment lookup and provisioning logic is currently split
-between:
-
-- `apps/server/src/lib/project-provisioning.ts`
-- `apps/server/src/lib/content-api.ts`
-- `apps/server/src/lib/schema-api.ts`
-- `apps/server/src/lib/environments-api.ts`
-
-CMS-19 will consolidate that logic into one server-owned module so each store
-resolves scope through the same path.
-
-## Architecture
-
-The internal project repository owns:
-
-- `findProjectBySlug`
-- `ensureProjectProvisioned`
-- `resolveProjectEnvironmentScope(project, environment, { createIfMissing })`
-- `requireProjectEnvironmentScope(...)`
-- `requireEnvironmentInProject(project, environmentId)`
-
-The route/store layers keep responsibility for mapping repository results into
-endpoint-specific `RuntimeError` responses.
-
-## Data Flow
-
-### Content store
-
-- replace the store-local `resolveScopeIds` helper with repository-backed scope
-  resolution
-- keep document reads and writes scoped by `(projectId, environmentId)`
-- keep wrong-project `documentId` access returning `NOT_FOUND`
-
-### Schema store
-
-- reuse the same repository helper for project/environment resolution
-- keep schema list/get/sync fully isolated to the resolved scope
-
-### Environment store
-
-- keep project-routed list/create/delete contracts unchanged
-- use the repository for provisioning and environment ownership checks
-
-## Provisioning Rules
-
-Preserve current behavior where it already exists:
-
-- environment creation may provision the project row and default `production`
-  environment transactionally
-- content creation keeps its current repository-backed scope resolution behavior
-
-CMS-19 should not broaden or normalize provisioning semantics beyond the current
-contract surface.
-
-## Error Handling
-
-Public error contracts remain unchanged.
-
-- content document operations keep returning `NOT_FOUND` for out-of-scope
-  documents
-- schema sync keeps returning `NOT_FOUND` when the routed project/environment
-  pair does not exist
-- environment delete keeps returning `NOT_FOUND` when the target environment ID
-  is not owned by the routed project
-
-Repository helpers return typed records or `undefined`; they do not raise
-endpoint-specific errors themselves.
-
-## Testing
-
-Add or tighten database-backed tests for:
-
-- content cross-project isolation
-- schema registry cross-project isolation
-- environment deletion with an environment ID that belongs to another project
-- repository provisioning and scope resolution behavior
-
-## Repo Policy Note
-
-This design file is intentionally stored in `docs/plans/` as a local planning
-artifact and should remain untracked per the repository instructions in
-`AGENTS.md`.

-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test apps/server/src/lib/project-provisioning.test.ts`

-
-**Step 2: Run test to verify it fails**

-# CMS-20 Locale Translation Groups Design
-
-## Scope
-
-Implement CMS-20 inside the existing server content API surface.
-
-In scope:
-
-- add translation-group creation semantics to `POST /api/v1/content`
-- preserve the existing response shape (`translationGroupId` is already exposed)
-- enforce project/environment scoping for variant creation
-- add deterministic conflict handling for duplicate locales within a translation
-  group
-- document the new operator-facing create contract in the server package docs
-
-Out of scope:
-
-- new routes for locale variants
-- Studio locale switcher UX and optional prefill flow (CMS-63)
-- clone/promote remapping behavior (later environment tasks)
-- full schema-aware validation for every content write path
-- migrations or table/index changes; the database already has the required
-  `translation_group_id` column and uniqueness index from CMS-11/CMS-12
-
-## Spec Delta Summary
-
-Confirmed contract delta for this task:
-
-- `POST /api/v1/content` gains optional `sourceDocumentId`
-- omitted `sourceDocumentId` keeps existing "create a brand new logical
-  document" semantics
-- provided `sourceDocumentId` creates a new locale variant in the same
-  translation group as the source document
-- `sourceDocumentId` is valid for any non-deleted source document in the routed
-  `project` and `environment`
-- the server derives `translation_group_id` from the source document; callers do
-  not send raw `translationGroupId`
-
-This closes the gap between:
-
-- the data model requirement that localized variants share a
-  `translation_group_id`
-- the Studio UX requirement that users can switch to an untranslated locale and
-  create the variant
-- the canonical content create contract, which previously had no way to express
-  "create a sibling translation of this existing document"
-
-## Approved Approach
-
-Keep one create endpoint and add an explicit variant-creation mode.
-
-`POST /api/v1/content` now has two behaviors:
-
-1. **New logical document**
-   - request omits `sourceDocumentId`
-   - server generates a new `document_id`
-   - server generates a new `translation_group_id`
-
-2. **New locale variant**
-   - request includes `sourceDocumentId`
-   - server resolves the source document within the routed scope
-   - server generates a new `document_id`
-   - server reuses the source document's `translation_group_id`
-
-This keeps the route surface minimal while making variant creation explicit and
-safe. The request does not accept raw `translationGroupId`, because that would
-let callers bypass scope and type checks.
-
-## Request Contract
-
-`POST /api/v1/content` continues to accept:
-
-- `path`
-- `type`
-- `locale`
-- `format`
-- `frontmatter`
-- `body`
-- optional actor fields
-
-New optional field:
-
-- `sourceDocumentId`
-
-Rules:
-
-- callers must still send the full draft payload; the server does not
-  auto-prefill content from the source document
-- Studio can implement optional prefill client-side later by reading the source
-  draft/published document and submitting copied content when desired
-- `path` remains explicit input; the server does not infer translation groups
-  from `path`
-
-## Validation and Data Flow
-
-### Variant creation
-
-When `sourceDocumentId` is present:
-
-1. resolve the source document inside the routed `project` and `environment`
-2. reject missing or soft-deleted sources with `NOT_FOUND`
-3. require request `type` to match the source document's `schema_type`
-4. resolve the source type's schema registry entry in the same scope
-5. reject variant creation for non-localized schema types with `INVALID_INPUT`
-6. validate that the requested locale does not already exist in the source
-   translation group for a non-deleted document
-7. create the new row with:
-   - fresh `document_id`
-   - inherited `translation_group_id`
-   - caller-provided `path`, `locale`, `format`, `frontmatter`, and `body`
-
-### Locale policy enforcement
-
-CMS-20 adds schema-backed locale validation only where it is required for the
-new translation-group behavior.
-
-- in variant-creation mode, the server uses scoped schema registry data to
-  verify that the type is localized and that the requested locale is allowed for
-  the environment's synced locale configuration
-- CMS-20 does **not** broaden content writes into full schema-aware validation
-  for every create/update path; that stays aligned with later content-core work
-
-This keeps the task scoped while preventing invalid translation-group writes.
-
-## Error Handling
-
-Existing deterministic errors remain unchanged where they still apply:
-
-- `CONTENT_PATH_CONFLICT` (`409`) remains the `(project, environment, locale,
-path)` uniqueness error
-- `NOT_FOUND` (`404`) remains the missing/out-of-scope/soft-deleted source
-  error for `sourceDocumentId`
-- `INVALID_INPUT` (`400`) covers malformed or invalid variant requests, such as:
-  - `sourceDocumentId` type mismatch
-  - `sourceDocumentId` used for a non-localized type
-  - locale rejected by the synced supported-locale set
-
-New deterministic conflict:
-
-- `TRANSLATION_VARIANT_CONFLICT` (`409`) when the translation group already has
-  a non-deleted document in the requested locale
-
-The DB-backed store should map the existing unique index on
-`(project_id, environment_id, translation_group_id, locale)` to
-`TRANSLATION_VARIANT_CONFLICT` so race conditions still return the same public
-error code.
-
-## Testing
-
-Add coverage in `apps/server/src/lib/content-api.test.ts` for:
-
-- in-memory create flow reusing `translationGroupId` when `sourceDocumentId` is
-  provided
-- duplicate locale rejection within one translation group
-- DB-backed variant creation reusing `translationGroupId` while generating a new
-  `documentId`
-- rejection of `sourceDocumentId` from another project/environment
-- rejection of soft-deleted sources
-- rejection of non-localized source types
-- rejection of unsupported locales for localized types
-
-Verification commands:
-
-- `bun test apps/server/src/lib/content-api.test.ts`
-- `bun run format:check`
-- `bun run check`
-
-## Documentation
-
-Document the new create contract in `apps/server/README.md` at the point of
-use:
-
-- `POST /api/v1/content` supports optional `sourceDocumentId`
-- omitted `sourceDocumentId` creates a new logical document
-- provided `sourceDocumentId` creates a locale variant in the source
-  translation group
-- duplicate locale conflicts return `TRANSLATION_VARIANT_CONFLICT`
-
-## Repo Policy Note
-
-This design file is intentionally stored in `docs/plans/` as a local planning
-artifact and should remain untracked per the repository instructions in
-`AGENTS.md`.

-# CMS-20 Locale Translation Groups Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Extend the server content create endpoint so locale variants can be created in the same translation group using `sourceDocumentId`, with deterministic validation and conflict handling.
-
-**Architecture:** Keep the existing `POST /api/v1/content` route and add an explicit variant-creation mode inside `apps/server/src/lib/content-api.ts`. Reuse the existing documents table and unique translation-locale index, add scoped source-document and schema-registry lookups in the DB-backed store, and cover the new behavior through in-memory and DB-backed content API tests.
-
-**Tech Stack:** Bun, TypeScript, Elysia route handlers, Drizzle ORM, postgres.js, node:test, Nx

-
-**Files:**
-

-
-**Step 1: Write the failing tests**
-
-```ts

-
-**Step 2: Run test to verify it fails**
-

-# CMS-23 + CMS-24 Restore and Version History Design
-
-## Scope
-
-Implement the bundled `CMS-23` and `CMS-24` server-side content behaviors
-inside the existing content API surface in `apps/server`.
-
-In scope:
-
-- add exact-undelete trash restore to `POST /api/v1/content/:documentId/restore`
-- add immutable version history read endpoints
-- add historical version restore to
-  `POST /api/v1/content/:documentId/versions/:version/restore`
-- preserve project/environment scoping, deterministic conflict handling, and
-  append-only version history guarantees
-- document the new API contract at the point of use in the server README
-
-Out of scope:
-
-- Studio trash/version-history UI
-- CLI commands for restore or history
-- schema-aware field validation beyond the current content write contract
-- collaboration merge semantics
-- new tables or indexes; the existing `documents` and `document_versions`
-  schema already support the required behavior
-
-## Spec Delta Summary
-
-Confirmed contract delta for this bundled implementation:
-
-- `POST /api/v1/content/:documentId/restore` is an exact undelete of the
-  current head row only
-- trash restore does **not** accept `targetStatus`
-- trash restore does **not** append a new `document_versions` row
-- trash restore preserves the current head state, including any existing
-  `publishedVersion`, and only clears `isDeleted`
-- `POST /api/v1/content/:documentId/versions/:version/restore` is the only
-  restore flow that accepts `targetStatus=draft|published`
-- `targetStatus=draft` updates mutable head content only
-- `targetStatus=published` appends a fresh immutable version row at HEAD and
-  updates `publishedVersion`
-
-This resolves the ambiguity between the current `SPEC-003` prose and endpoint
-table by keeping plain trash restore as undelete-only and leaving publish-style
-restoration on the version-restore endpoint.
-
-## Approved Approach
-
-Keep the work inside the existing content API module and extend the current
-store abstraction.
-
-The implementation will:
-
-1. extend `ContentStore` with `restore`, `listVersions`, `getVersion`, and
-   `restoreVersion`
-2. keep in-memory and DB-backed stores aligned so HTTP tests exercise the same
-   public contract in both modes
-3. reuse the existing publish flow semantics for restore-to-published so the
-   version history remains linear and append-only
-4. centralize path-conflict handling so both trash restore and version restore
-   return the same deterministic `CONTENT_PATH_CONFLICT` error shape
-
-This keeps the task scoped to the existing server boundary while preserving the
-behavioral guarantees already established by the content API.
-
-## Request Contract
-
-### `POST /api/v1/content/:documentId/restore`
-
-- no request body fields are required
-- exact undelete of the current head row
-- clears `isDeleted`
-- preserves current head content and `publishedVersion`
-- does not append version history
-
-### `GET /api/v1/content/:documentId/versions`
-
-- returns immutable publish history for the routed document
-- response items are version summaries derived from `document_versions`
-
-### `GET /api/v1/content/:documentId/versions/:version`
-
-- returns one immutable snapshot from `document_versions`
-
-### `POST /api/v1/content/:documentId/versions/:version/restore`
-
-- accepts optional `targetStatus` enum: `draft` or `published`
-- default is `draft`
-- `draft` updates the mutable head from the chosen immutable snapshot and sets
-  `hasUnpublishedChanges = true`
-- `published` updates the mutable head from the chosen immutable snapshot,
-  appends a new immutable publish row, and updates `publishedVersion`
-
-## Validation and Data Flow
-
-### Trash restore
-
-When restoring a soft-deleted document:
-
-1. resolve the document within the routed `project` and `environment`
-2. reject missing documents with `NOT_FOUND`
-3. reject already-active documents by returning the current active head
-   semantics only if explicitly supported; for this task, only deleted documents
-   are restorable
-4. check whether another active document already occupies the same
-   `(project, environment, locale, path)` tuple
-5. if no conflict exists, clear `isDeleted` and return the restored head
-
-### Version history reads
-
-1. resolve the document within the routed scope
-2. reject missing or soft-deleted targets with `NOT_FOUND`
-3. read immutable rows from `document_versions` for that `documentId`
-4. return descending version order for list responses
-
-### Version restore
-
-When restoring a historical version:
-
-1. resolve the head document within the routed scope
-2. resolve the requested immutable version row for the same `documentId`
-3. reject malformed versions with `INVALID_INPUT`
-4. reject missing snapshots with `NOT_FOUND`
-5. check active path uniqueness against the snapshot path and locale
-6. update the mutable head from the snapshot
-7. for `targetStatus=draft`, set `hasUnpublishedChanges = true` and do not
-   append a version row
-8. for `targetStatus=published`, append a fresh immutable version row and set
-   `publishedVersion` to the new HEAD version number
-
-## Error Handling
-
-Deterministic errors for the bundled work:
-
-- `INVALID_INPUT` (`400`)
-  - malformed `version` path parameter
-  - invalid `targetStatus`
-- `NOT_FOUND` (`404`)
-  - document missing in the routed scope
-  - requested immutable version missing for the document
-- `CONTENT_PATH_CONFLICT` (`409`)
-  - trash restore or version restore would reactivate/update the head into an
-    active `(project, environment, locale, path)` collision
-
-Conflict details should include:
-
-- `path`
-- `locale`
-- `conflictDocumentId` when available
-
-## Testing
-
-Add coverage in `apps/server/src/lib/content-api.test.ts` for:
-
-- in-memory trash restore exact undelete
-- in-memory trash restore conflict handling
-- in-memory version history listing and single-version fetch
-- in-memory draft version restore
-- in-memory published version restore appending a fresh HEAD version
-- DB-backed trash restore conflict handling
-- DB-backed published version restore preserving linear append-only history
-
-Verification commands:
-
-- `bun test apps/server/src/lib/content-api.test.ts`
-- `bun run format:check`
-- `bun run check`
-
-## Documentation
-
-Document the new content contracts in `apps/server/README.md`:
-
-- trash restore is exact undelete of the current head
-- version history endpoints expose immutable publish snapshots
-- version restore supports `targetStatus=draft|published`
-- restore conflicts return `CONTENT_PATH_CONFLICT`
-
-## Repo Policy Note
-
-This design file is intentionally stored in `docs/plans/` as a local planning
-artifact and should remain untracked per the repository instructions in
-`AGENTS.md`.

-# CMS-23 + CMS-24 Restore and Version History Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Add exact trash restore, immutable version-history reads, and
-historical version restore semantics to the server content API.
-
-**Architecture:** Extend the existing content store contract inside
-`apps/server/src/lib/content-api.ts` so the in-memory and DB-backed stores both
-implement the same restore/version behaviors. Keep route orchestration in the
-current content API module, reuse existing publish semantics for
-restore-to-published, and cover the new behavior primarily through
-HTTP-level tests in `apps/server/src/lib/content-api.test.ts`.
-
-**Tech Stack:** Bun, TypeScript, Elysia route handlers, Drizzle ORM,
-postgres.js, node:test, Nx
-
----
-
-### Task 1: Add Failing Tests for Trash Restore and Version History
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api.test.ts`
-
-**Step 1: Write the failing tests**
-
-```ts
-test("content API restore undeletes the current head without appending a version", async () => {
-  const handler = createHandler();
-
-  // Create, publish, soft-delete, restore, then assert:
-  // - restore returns 200
-  // - isDeleted is false
-  // - publishedVersion is unchanged
-  // - version list length is still 1
-});
-
-test("content API returns version history summaries and individual snapshots", async () => {
-  const handler = createHandler();
-
-  // Create, publish twice, then assert GET /versions and GET /versions/:version.
-});
-
-test("content API restores a historical version to draft state by default", async () => {
-  const handler = createHandler();
-
-  // Publish v1, update + publish v2, restore v1 with no targetStatus, then
-  // assert head content matches v1 and history length remains 2.
-});
-
-test("content API restores a historical version to published state when requested", async () => {
-  const handler = createHandler();
-
-  // Publish v1, publish v2, restore v1 with targetStatus=published, then
-  // assert a new version 3 exists and publishedVersion is 3.
-});
-```
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test apps/server/src/lib/content-api.test.ts`
-Expected: FAIL because the restore and version-history routes do not exist yet.
-
-**Step 3: Write minimal implementation**
-
-```ts
-type ContentVersionSummary = {
-  version: number;
-  path: string;
-  locale: string;
-  type: string;
-  format: ContentFormat;
-  publishedAt: string;
-  publishedBy: string;
-  changeSummary?: string;
-};
-
-type ContentVersionDocument = ContentVersionSummary & {
-  documentId: string;
-  translationGroupId: string;
-  frontmatter: Record<string, unknown>;
-  body: string;
-};
-
-type ContentRestoreVersionPayload = {
-  targetStatus?: string;
-  actorId?: unknown;
-  changeSummary?: unknown;
-  change_summary?: unknown;
-};
-```
-
-Extend the in-memory store and route handlers just enough to make the new tests
-pass before touching the DB-backed parity cases.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test apps/server/src/lib/content-api.test.ts`
-Expected: PASS for the new in-memory restore/version coverage.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api.test.ts apps/server/src/lib/content-api.ts
-git commit -m "feat(server): add content restore and version history routes"
-```
-
-### Task 2: Add DB-Backed Restore and Version-Restore Behavior
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api.ts`
-- Modify: `apps/server/src/lib/content-api.test.ts`
-
-**Step 1: Write the failing DB-backed tests**
-
-```ts
-testWithDatabase(
-  "content API DB restore returns CONTENT_PATH_CONFLICT when undelete collides with an active path",
-  async () => {
-    // Create doc A, soft-delete it, create doc B with the same path/locale,
-    // restore doc A, then assert 409 CONTENT_PATH_CONFLICT.
-  },
-);
-
-testWithDatabase(
-  "content API DB restore version with targetStatus=published appends a new immutable version",
-  async () => {
-    // Publish v1, publish v2, restore v1 to published, then assert:
-    // - publishedVersion is 3
-    // - document_versions now has 3 rows
-    // - version 3 body/frontmatter/path match v1
-  },
-);
-```
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test apps/server/src/lib/content-api.test.ts`
-Expected: FAIL because the DB-backed store does not yet implement restore or
-version-history operations.
-
-**Step 3: Write minimal implementation**
-
-```ts
-async restore(scope, documentId) {
-  // Resolve scope ids and current document row.
-  // Reject missing rows with NOT_FOUND.
-  // Check active path uniqueness excluding the current document id.
-  // Clear isDeleted and return the updated head row.
-}
-
-async restoreVersion(scope, documentId, version, input) {
-  // Resolve document + immutable version snapshot in one transaction.
-  // Check path uniqueness against the snapshot path/locale.
-  // Update the head row from the snapshot.
-  // If targetStatus === "published", append a fresh version row and set
-  // publishedVersion to the new version number.
-}
-```
-
-Map unique/path conflicts to `CONTENT_PATH_CONFLICT` with consistent details in
-both restore flows.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test apps/server/src/lib/content-api.test.ts`
-Expected: PASS for the new DB-backed restore/version tests.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api.ts apps/server/src/lib/content-api.test.ts
-git commit -m "feat(server): add DB-backed restore semantics"
-```
-
-### Task 3: Document the Operator-Facing Contract and Run Verification
-
-**Files:**
-
-- Modify: `apps/server/README.md`
-
-**Step 1: Write the failing doc expectation**
-
-```md
-- `POST /api/v1/content/:documentId/restore` undeletes the current head only.
-- `GET /api/v1/content/:documentId/versions` lists immutable publish history.
-- `GET /api/v1/content/:documentId/versions/:version` returns one immutable snapshot.
-- `POST /api/v1/content/:documentId/versions/:version/restore` restores a snapshot to draft or published state.
-```
-
-**Step 2: Run check to verify docs are missing**
-
-Run: `rg -n "documentId/restore|versions/:version/restore" apps/server/README.md`
-Expected: missing or incomplete entries for the new restore/version contract.
-
-**Step 3: Write minimal implementation**
-
-Add a short API contract section in `apps/server/README.md` describing the new
-endpoints, the exact-undelete trash restore behavior, and the `CONTENT_PATH_CONFLICT`
-restore error.
-
-**Step 4: Run verification**
-
-Run: `bun test apps/server/src/lib/content-api.test.ts`
-Expected: PASS
-
-Run: `bun run format:check`
-Expected: PASS
-
-Run: `bun run check`
-Expected: PASS

-# CMS-38 CSRF Enforcement Design
-
-Date: 2026-03-12
-Status: approved in chat, local planning artifact only
-
-## Goal
-
-Implement CSRF enforcement for session-authenticated, state-changing Studio API requests without changing API-key behavior.
-
-## Source Of Truth
-
-- Roadmap task: `CMS-38` in `ROADMAP_TASKS.md`
-- Owning auth spec: `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
-- Related endpoint specs:
-  - `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
-  - `docs/specs/SPEC-004-schema-system-and-sync.md`
-  - `docs/specs/SPEC-009-i18n-and-environments.md`
-  - `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-
-## Approved Spec Delta
-
-Add a concrete CSRF contract to `SPEC-005`:
-
-- Session-authenticated `POST`, `PUT`, `PATCH`, and `DELETE` requests require CSRF validation.
-- The server issues a readable cookie named `mdcms_csrf`.
-- The client must echo the same value in the `x-mdcms-csrf-token` request header.
-- A state-changing session request is accepted only when:
-  - the Studio session cookie is valid,
-  - the `mdcms_csrf` cookie is present,
-  - the `x-mdcms-csrf-token` header is present,
-  - the cookie value and header value match.
-- API-key authenticated requests are exempt from CSRF enforcement.
-- Read-only requests (`GET`, `HEAD`, `OPTIONS`) are exempt.
-- Public auth routes are exempt:
-  - `/api/v1/auth/login`
-  - `/api/v1/auth/sign-up/email`
-  - `/api/v1/auth/sign-in/email`
-  - `/api/v1/auth/cli/login/*`
-- CSRF failures return deterministic authz semantics:
-  - status `403`
-  - code `FORBIDDEN`
-  - message `Valid CSRF token is required for session-authenticated state-changing requests.`
-
-## Server Design
-
-Keep CSRF enforcement server-side in `apps/server/src/lib/auth.ts`, with a shared helper used by first-party mutation handlers.
-
-### Token Lifecycle
-
-- Mint a random CSRF token on successful `POST /api/v1/auth/login`.
-- Also mint and return the token on successful session bootstrap reads:
-  - `GET /api/v1/auth/session`
-  - `GET /api/v1/auth/get-session`
-- Clear the CSRF cookie on:
-  - `POST /api/v1/auth/logout`
-  - `POST /api/v1/auth/sign-out`
-
-This lets the Studio recover a token when the browser already has a valid session cookie.
-
-### Enforcement Rule
-
-The shared helper should:
-
-1. Skip CSRF validation when the request is not state-changing.
-2. Skip CSRF validation when the request authenticates with `Authorization: Bearer ...` because that is an API-key flow, not a cookie-backed Studio session.
-3. If no bearer token is present, check whether a valid session exists.
-4. If there is a valid session and the request is state-changing, require matching `mdcms_csrf` cookie and `x-mdcms-csrf-token` header values.
-5. If there is no valid session, do not transform the failure; let the existing auth path return `401`.
-
-This preserves current `401` vs `403` behavior and keeps the scope explicit.
-
-## Endpoint Coverage
-
-Apply the guard only to first-party state-changing routes that can be session-authenticated:
-
-- Auth mutation routes in `apps/server/src/lib/auth.ts`
-  - `POST /api/v1/auth/logout`
-  - `POST /api/v1/auth/api-keys`
-  - `POST /api/v1/auth/api-keys/:keyId/revoke`
-  - `POST /api/v1/auth/users/:userId/sessions/revoke-all`
-- Content mutations in `apps/server/src/lib/content-api/routes.ts`
-- Schema sync mutation in `apps/server/src/lib/schema-api.ts`
-- Environment mutations in `apps/server/src/lib/environments-api.ts`
-
-Do not apply the guard to:
-
-- login and sign-up routes
-- CLI browser-login routes
-- API-key self-revoke route
-- read-only routes
-
-## Testing Strategy
-
-Primary acceptance tests:
-
-- session mutation succeeds with matching CSRF cookie and header
-- session mutation fails when header is missing
-- session mutation fails when CSRF cookie is missing
-- session mutation fails when values mismatch
-- API-key mutation remains allowed without CSRF
-- login/session bootstrap routes emit `mdcms_csrf`
-- logout/sign-out clear `mdcms_csrf`
-
-Route-level regression coverage:
-
-- content mutation test in `apps/server/src/lib/content-api.test.ts`
-- schema sync test in `apps/server/src/lib/schema-api.test.ts`
-- environment mutation test in `apps/server/src/lib/environments-api.test.ts`
-
-## Documentation
-
-- Update `SPEC-005` with the concrete CSRF contract.
-- Add a short code comment near the shared guard in `auth.ts` explaining the session-only enforcement rule.
-
-## Validation
-
-Run from workspace root:
-
-- `bun test apps/server/src/lib/auth.test.ts`
-- `bun test apps/server/src/lib/content-api.test.ts`
-- `bun test apps/server/src/lib/schema-api.test.ts`
-- `bun test apps/server/src/lib/environments-api.test.ts`
-- `bun run format:check`
-- `bun run check`
-
-## Notes
-
-- `docs/plans/` is intentionally local-only in this repository and should remain untracked.

-
-**Architecture:** Add one shared CSRF utility layer in the server auth module, issue a readable CSRF cookie alongside session bootstrap responses, and invoke the guard from first-party mutation handlers that accept session auth.

-
----
-
-### Task 1: Codify The Contract In The Owning Spec
-
-**Files:**
-
-- Modify: `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
-
-**Step 1: Add the normative CSRF contract text**
-
-Insert a short normative subsection under Session Security and update the auth endpoint table notes with:
-
-```md
-- Session-authenticated POST/PUT/PATCH/DELETE requests require CSRF validation.
-- The server sets a readable `mdcms_csrf` cookie.
-- Clients must echo that value in `x-mdcms-csrf-token`.
-- API-key requests are exempt.
-- CSRF failures return `FORBIDDEN` (`403`).
-```
-
-**Step 2: Verify the spec matches the approved design**
-
-Check these exact behaviors are present:
-
-- cookie name: `mdcms_csrf`
-- header name: `x-mdcms-csrf-token`
-- protected methods: `POST`, `PUT`, `PATCH`, `DELETE`
-- exemptions: read-only methods, API-key requests, login/sign-up/CLI login routes
-
-**Step 3: Commit the spec change separately if using commit checkpoints**
-
-```bash
-git add docs/specs/SPEC-005-auth-authorization-and-request-routing.md
-git commit -m "docs: define CSRF contract for Studio mutations"
-```
-
-### Task 2: Add Failing Auth-Level CSRF Tests
-
-**Files:**
-
-- Modify: `apps/server/src/lib/auth.test.ts`
-
-**Step 1: Add helpers for CSRF cookie extraction and header injection**
-
-Add small helpers near the existing auth test utilities:
-
-```ts
-function extractCookieValue(
-  setCookie: string,
-  name: string,
-): string | undefined {
-  return setCookie
-    .split(/,\s*/)
-    .flatMap((chunk) => chunk.split(";"))
-    .map((part) => part.trim())
-    .find((part) => part.startsWith(`${name}=`))
-    ?.slice(name.length + 1);
-}
-```
-
-**Step 2: Write failing tests for the approved contract**
-
-Add tests that assert:
-
-- login returns a `set-cookie` containing `mdcms_csrf=`
-- `GET /api/v1/auth/session` reissues `mdcms_csrf=`
-- `POST /api/v1/auth/api-keys` with session cookie but no CSRF header returns `403`
-- the same route with mismatched header returns `403`
-- the same route with matching cookie/header returns `200`
-- `POST /api/v1/auth/logout` clears `mdcms_csrf`
-
-Example request shape:
-
-```ts
-new Request("http://localhost/api/v1/auth/api-keys", {
-  method: "POST",
-  headers: {
-    "content-type": "application/json",
-    cookie: `${sessionCookie}; mdcms_csrf=${csrfToken}`,
-    "x-mdcms-csrf-token": csrfToken,
-  },
-  body: JSON.stringify(payload),
-});
-```
-
-**Step 3: Run the focused auth test file and confirm failure**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-
-Expected: FAIL on the new CSRF assertions because the server does not issue or enforce the token yet.
-
-**Step 4: Commit the red test stage if using TDD checkpoints**
-
-```bash
-git add apps/server/src/lib/auth.test.ts
-git commit -m "test(server): add CMS-38 auth csrf coverage"
-```
-
-### Task 3: Implement CSRF Utilities And Token Issuance
-
-**Files:**
-
-- Modify: `apps/server/src/lib/auth.ts`
-
-**Step 1: Add CSRF constants and cookie helpers**
-
-Add constants near the existing auth constants:
-
-```ts
-const CSRF_COOKIE_NAME = "mdcms_csrf";
-const CSRF_HEADER_NAME = "x-mdcms-csrf-token";
-```
-
-Add helpers for:
-
-- generating a token with `randomBytes`
-- serializing the readable CSRF cookie
-- serializing a clearing cookie
-- reading a named cookie from the request
-
-**Step 2: Add a shared enforcement helper**
-
-Create a helper with behavior like:
-
-```ts
-async function requireCsrfForSessionMutation(request: Request): Promise<void> {
-  if (!isStateChangingMethod(request.method)) return;
-  if (extractBearerToken(request.headers.get("authorization"))) return;
-
-  const session = await getSessionIfAvailable(request);
-  if (!session) return;
-
-  const cookieToken = readCookie(request, CSRF_COOKIE_NAME);
-  const headerToken = request.headers.get(CSRF_HEADER_NAME)?.trim();
-  if (!cookieToken || !headerToken || cookieToken !== headerToken) {
-    throw new RuntimeError({
-      code: "FORBIDDEN",
-      message:
-        "Valid CSRF token is required for session-authenticated state-changing requests.",
-      statusCode: 403,
-    });
-  }
-}
-```
-
-Include a short code comment explaining why API-key requests are exempt.
-
-**Step 3: Issue CSRF cookies on session bootstrap responses**
-
-Update:
-
-- `login()` to include a CSRF cookie alongside the session cookie
-- `/api/v1/auth/session` and `/api/v1/auth/get-session` responses to set `mdcms_csrf`
-- `logout()` to clear `mdcms_csrf`
-- `handleAuthRequest` sign-out path to clear `mdcms_csrf` if the route is `/api/v1/auth/sign-out`
-
-If multiple cookies are set in one response, preserve the session cookie and append the CSRF cookie in the same `set-cookie` header string format already used by the server.
-
-**Step 4: Re-run auth tests**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-
-Expected: auth-level CSRF tests now pass or narrow failures to downstream route coverage still awaiting integration.
-
-**Step 5: Commit the auth implementation**
-
-```bash
-git add apps/server/src/lib/auth.ts apps/server/src/lib/auth.test.ts
-git commit -m "feat(server): add session csrf token handling"
-```
-
-### Task 4: Enforce CSRF On Auth Mutation Routes
-
-**Files:**
-
-- Modify: `apps/server/src/lib/auth.ts`
-
-**Step 1: Call the shared CSRF guard at the top of protected auth mutations**
-
-Add `await options.authService.requireCsrfProtection(request)` or equivalent shared helper call before:
-
-- `POST /api/v1/auth/logout`
-- `POST /api/v1/auth/users/:userId/sessions/revoke-all`
-- `POST /api/v1/auth/api-keys`
-- `POST /api/v1/auth/api-keys/:keyId/revoke`
-
-Do not enforce the guard on:
-
-- `POST /api/v1/auth/login`
-- better-auth sign-up/sign-in
-- CLI login routes
-- `POST /api/v1/auth/api-keys/self/revoke`
-
-**Step 2: Run auth tests again**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-
-Expected: PASS
-
-**Step 3: Commit the route enforcement change**
-
-```bash
-git add apps/server/src/lib/auth.ts
-git commit -m "feat(server): enforce csrf on auth session mutations"
-```
-
-### Task 5: Enforce CSRF On Content Mutations
-
-**Files:**
-
-- Modify: `apps/server/src/lib/auth.ts`
-- Modify: `apps/server/src/lib/content-api/routes.ts`
-- Modify: `apps/server/src/lib/content-api/types.ts`
-- Modify: `apps/server/src/lib/content-api.test.ts`
-
-**Step 1: Expose the CSRF guard through the existing route authorizer surface**
-
-Prefer the smallest change that avoids duplicating auth internals:
-
-- either extend the auth service with a dedicated `requireCsrfProtection(request)` method
-- or extend `MountContentApiRoutesOptions` with a separate `requireCsrf` callback
-
-Keep the route contract explicit rather than reaching into auth internals from content routes.
-
-**Step 2: Add failing content-route tests**
-
-Add tests for a representative session-backed mutation such as `POST /api/v1/content`:
-
-- missing CSRF header returns `403`
-- matching CSRF cookie/header returns `200`
-- API-key request still succeeds without CSRF when scopes allow it
-
-**Step 3: Wire the guard into all content mutations**
-
-Invoke the guard before authorization/store calls in:
-
-- `POST /api/v1/content`
-- `PUT /api/v1/content/:documentId`
-- `POST /api/v1/content/:documentId/publish`
-- `POST /api/v1/content/:documentId/unpublish`
-- `DELETE /api/v1/content/:documentId`
-- `POST /api/v1/content/:documentId/restore`
-- `POST /api/v1/content/:documentId/versions/:version/restore`
-
-**Step 4: Run the focused content test file**
-
-Run: `bun test apps/server/src/lib/content-api.test.ts`
-
-Expected: PASS
-
-**Step 5: Commit the content enforcement**
-
-```bash
-git add apps/server/src/lib/auth.ts apps/server/src/lib/content-api/routes.ts apps/server/src/lib/content-api/types.ts apps/server/src/lib/content-api.test.ts
-git commit -m "feat(server): enforce csrf on content mutations"
-```
-
-### Task 6: Enforce CSRF On Schema And Environment Mutations
-
-**Files:**
-
-- Modify: `apps/server/src/lib/runtime-with-modules.ts`
-- Modify: `apps/server/src/lib/schema-api.ts`
-- Modify: `apps/server/src/lib/schema-api.test.ts`
-- Modify: `apps/server/src/lib/environments-api.ts`
-- Modify: `apps/server/src/lib/environments-api.test.ts`
-
-**Step 1: Extend the route mount options if needed**
-
-If schema/environment route mounts only receive authz callbacks today, add a parallel CSRF callback so they can opt into the shared guard without re-implementing auth logic.
-
-**Step 2: Add failing schema/environment tests**
-
-Add one representative session-backed mutation test per surface:
-
-- `PUT /api/v1/schema` without CSRF returns `403`
-- `POST /api/v1/environments` without CSRF returns `403`
-- matching CSRF cookie/header succeeds
-
-**Step 3: Implement route-level enforcement**
-
-Invoke the shared guard before the existing mutation logic in:
-
-- `PUT /api/v1/schema`
-- `POST /api/v1/environments`
-- `DELETE /api/v1/environments/:id`
-
-**Step 4: Run the focused test files**
-
-Run: `bun test apps/server/src/lib/schema-api.test.ts`
-Expected: PASS
-
-Run: `bun test apps/server/src/lib/environments-api.test.ts`
-Expected: PASS
-
-**Step 5: Commit the schema/environment enforcement**
-
-```bash
-git add apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/schema-api.ts apps/server/src/lib/schema-api.test.ts apps/server/src/lib/environments-api.ts apps/server/src/lib/environments-api.test.ts
-git commit -m "feat(server): enforce csrf on schema and environment mutations"
-```
-
-### Task 7: Final Verification And Hygiene
-
-**Files:**
-
-- Verify only task-scoped changes are staged
-
-**Step 1: Run the touched test files together**
-
-Run: `bun test apps/server/src/lib/auth.test.ts apps/server/src/lib/content-api.test.ts apps/server/src/lib/schema-api.test.ts apps/server/src/lib/environments-api.test.ts`
-
-Expected: PASS
-
-**Step 2: Run repository validation commands**
-
-Run: `bun run format:check`
-Expected: PASS
-
-Run: `bun run check`
-Expected: PASS
-
-**Step 3: Inspect git status**
-
-Run: `git status --short`
-
-Expected:
-
-- only task-scoped source/spec changes are tracked
-- `docs/plans/` remains untracked
-- local-only files from `AGENTS.md` stay unstaged
-
-**Step 4: Create the final task-scoped commit if needed**
-
-```bash
-git add apps/server/src/lib/auth.ts apps/server/src/lib/auth.test.ts apps/server/src/lib/content-api/routes.ts apps/server/src/lib/content-api/types.ts apps/server/src/lib/content-api.test.ts apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/schema-api.ts apps/server/src/lib/schema-api.test.ts apps/server/src/lib/environments-api.ts apps/server/src/lib/environments-api.test.ts docs/specs/SPEC-005-auth-authorization-and-request-routing.md

-# Content API Refactor Design
-
-## Scope
-
-Refactor `apps/server/src/lib/content-api.ts` into smaller internal modules
-without changing any behavior, public exports, route contracts, or existing
-test expectations.
-
-In scope:
-
-- keep `apps/server/src/lib/content-api.ts` as the stable public entrypoint
-- extract shared content API types into an internal module
-- extract parsing/routing helpers into an internal module
-- extract response and row conversion helpers into an internal module
-- extract the in-memory content store into its own module
-- extract the DB-backed content store into its own module
-- extract route mounting into its own module
-- preserve the current test suite as the regression guard
-
-Out of scope:
-
-- endpoint behavior changes
-- route path or payload changes
-- new tests for new behavior
-- cleanup refactors unrelated to file decomposition
-- broader server architecture changes
-
-## Spec Delta Summary
-
-There is no product-spec delta for this work. This is a no-behavior-change
-internal refactor of the current server implementation.
-
-The contract that must remain unchanged is the existing public surface exported
-by `apps/server/src/lib/content-api.ts`:
-
-- `createInMemoryContentStore`
-- `createDatabaseContentStore`
-- `mountContentApiRoutes`
-
-Acceptance for this refactor depends on preserving:
-
-- existing content API runtime behavior
-- existing request/response contracts
-- existing test outcomes
-
-## Approved Approach
-
-Use a thin facade entrypoint and move internals into
-`apps/server/src/lib/content-api/`.
-
-Target structure:
-
-- `content-api.ts`
-- `content-api/types.ts`
-- `content-api/parsing.ts`
-- `content-api/responses.ts`
-- `content-api/in-memory-store.ts`
-- `content-api/database-store.ts`
-- `content-api/routes.ts`
-
-This is the safest split because it reduces the file size quickly while keeping
-the rest of the codebase importing the same top-level module path.
-
-## Migration Strategy
-
-1. Extract pure/shared code first:
-   - content types
-   - payload/query types
-   - parsing helpers
-   - response serializers
-2. Extract `createInMemoryContentStore` and keep its private helper functions
-   local to that module.
-3. Extract `createDatabaseContentStore` and keep DB-only helper functions local
-   to that module.
-4. Extract `mountContentApiRoutes` last, after shared helpers and store exports
-   are already stable.
-5. Reduce `content-api.ts` to a thin re-export facade.
-
-## Guardrails
-
-- no public API changes
-- no route changes
-- no behavior changes
-- no test rewrites beyond import-stability needs
-- no opportunistic cleanups mixed into the extraction
-
-## Risks
-
-- accidental type cycles between shared helpers and store modules
-- import path mistakes when moving helpers
-- behavioral drift between in-memory and DB stores if helpers are duplicated
-- route authorization regressions if helper ownership changes
-
-## Mitigation
-
-- keep shared types/helpers in dedicated internal modules
-- keep store-specific helpers private to the relevant store module
-- extract routes last
-- run the existing content API test file after each major extraction step
-
-## Testing
-
-Primary regression gate:
-
-- `bun test apps/server/src/lib/content-api.test.ts`
-
-Full validation after the refactor:
-
-- `bun run format:check`
-- `bun run check`
-
-## Repo Policy Note
-
-This design file is intentionally stored in `docs/plans/` as a local planning
-artifact and should remain untracked per `AGENTS.md`.

-# Content API Refactor Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Break `apps/server/src/lib/content-api.ts` into smaller internal
-modules while keeping the same public entrypoint and preserving all current
-behavior.
-
-**Architecture:** Keep `apps/server/src/lib/content-api.ts` as the only public
-import surface and move its internals into `apps/server/src/lib/content-api/`.
-Extract shared pure helpers first, then the in-memory store, DB-backed store,
-and route mounting, with the existing content API test suite acting as the
-behavioral safety net throughout the refactor.
-
-**Tech Stack:** Bun, TypeScript, Elysia route handlers, Drizzle ORM,
-postgres.js, node:test, Nx

-# CMS-39 Login Backoff And Failed-Attempt Throttling Design
-
-Date: 2026-03-13
-Status: approved in chat, local planning artifact only
-
-## Goal
-
-Implement deterministic failed-password throttling for MDCMS password-entry flows, with exponential backoff that becomes observable as `429 AUTH_BACKOFF_ACTIVE` responses.
-
-## Source Of Truth
-
-- Roadmap task: `CMS-39` in `ROADMAP_TASKS.md`
-- Owning auth spec: `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
-- Server auth implementation: `apps/server/src/lib/auth.ts`
-- Server auth docs: `apps/server/README.md`
-
-## Approved Spec Delta
-
-Add a concrete throttling contract to `SPEC-005`:
-
-- Failed password login attempts use exponential backoff.
-- The protected password-entry routes are:
-  - `POST /api/v1/auth/login`
-  - `POST /api/v1/auth/cli/login/authorize` when credentials are submitted
-- Backoff state is keyed by normalized email for MVP scope.
-- Invalid credentials without an active backoff return:
-  - status `401`
-  - code `AUTH_INVALID_CREDENTIALS`
-- Requests made while backoff is active return:
-  - status `429`
-  - code `AUTH_BACKOFF_ACTIVE`
-  - header `Retry-After: <seconds>`
-- Backoff resets on successful password sign-in.
-- Backoff also resets after a quiet window of 15 minutes without failed attempts.
-- Exponential schedule for MVP:
-  - attempt 1 sets next delay to `1s`
-  - attempt 2 sets next delay to `2s`
-  - attempt 3 sets next delay to `4s`
-  - attempt 4 sets next delay to `8s`
-  - attempt 5 sets next delay to `16s`
-  - attempt 6+ cap at `32s`
-
-## Server Design
-
-Keep Better Auth responsible for credential verification and session issuance, but own the throttling contract in MDCMS.
-
-### Why Not Better Auth Rate Limiting
-
-- Better Auth has a built-in rate limiter, but MDCMS currently calls `auth.api.signInEmail(...)` server-side in its own wrapper.
-- Better Auth documents that server-side `auth.api` requests are not rate limited.
-- The built-in limiter is request-path based, while `CMS-39` needs failed-attempt-aware exponential backoff with MDCMS-owned status codes and reset rules.
-
-### Persistence Model
-
-Persist throttle state in Postgres so behavior is deterministic across process restarts and test runs.
-
-Proposed table shape:
-
-- `login_key` text primary/unique key
-- `failure_count` integer
-- `first_failed_at` timestamp
-- `last_failed_at` timestamp
-- `next_allowed_at` timestamp
-- `created_at` timestamp
-- `updated_at` timestamp
-
-`login_key` should be the normalized email used for password login attempts.
-
-### Request Flow
-
-For `POST /api/v1/auth/login` and password-backed CLI authorize:
-
-1. Normalize the email.
-2. Read the throttle row for that login key.
-3. If `next_allowed_at > now`, reject immediately with `429 AUTH_BACKOFF_ACTIVE` and `Retry-After`.
-4. If the quiet window has elapsed, treat the row as reset before processing this attempt.
-5. Call Better Auth to verify credentials.
-6. On success:
-   - delete or reset the throttle row
-   - continue with existing session issuance behavior
-7. On invalid credentials:
-   - increment `failure_count`
-   - compute the next delay using the capped exponential schedule
-   - set `last_failed_at` and `next_allowed_at`
-   - return the existing `401 AUTH_INVALID_CREDENTIALS`
-
-This keeps credential failures and active lockout as separate deterministic states.
-
-## Endpoint Coverage
-
-Apply the throttle guard only to password-entry routes owned by `SPEC-005`:
-
-- `POST /api/v1/auth/login`
-- `POST /api/v1/auth/cli/login/authorize` when `email` and `password` are present
-
-Do not apply it to:
-
-- `GET /api/v1/auth/cli/login/authorize`
-- API key flows
-- session reads
-- logout/revoke routes
-- future SSO providers
-
-## Error Handling
-
-- Active backoff returns:
-  - HTTP `429`
-  - code `AUTH_BACKOFF_ACTIVE`
-  - message `Too many failed login attempts. Retry after <seconds> seconds.`
-  - `Retry-After` response header
-- Invalid credentials outside active backoff keep the existing:
-  - HTTP `401`
-  - code `AUTH_INVALID_CREDENTIALS`
-- Internal persistence failures remain `500 INTERNAL_ERROR`
-
-## Testing Strategy
-
-Primary acceptance coverage should prove:
-
-- repeated failed password attempts create exponential backoff state
-- login requests made during backoff return `429` with `Retry-After`
-- successful login clears backoff state
-- quiet-window expiry resets the counter
-- CLI browser authorize shares the same throttling behavior when credentials are posted
-
-Suggested test technique:
-
-- add focused auth tests in `apps/server/src/lib/auth.test.ts`
-- inject or control the clock in auth throttling helpers, or temporarily stub `Date.now()` in tests
-- validate both response semantics and persisted DB state where that gives better signal
-
-## Documentation
-
-- Update `SPEC-005` with the concrete `429` contract.
-- Update `apps/server/README.md` with the new auth abuse behavior and operator-visible response semantics.
-- Add a short code comment near the throttling helper in `auth.ts` explaining why MDCMS owns this logic instead of relying on Better Auth rate limiting.

-# CMS-39 Login Backoff And Failed-Attempt Throttling Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Add deterministic password-login throttling with persisted exponential backoff, `429 AUTH_BACKOFF_ACTIVE` responses during active lockout, and reset-on-success behavior for the MDCMS auth flows owned by `SPEC-005`.
-
-**Architecture:** Update `SPEC-005` first, then add a small persisted throttle table in the server schema so backoff state survives process restarts and can be tested deterministically. Route both `POST /api/v1/auth/login` and the credential-submission branch of `POST /api/v1/auth/cli/login/authorize` through a shared auth helper that checks active backoff, records failures, clears state on success, and surfaces `Retry-After` on `429`.
-
-**Tech Stack:** Bun, TypeScript, Elysia, better-auth, Drizzle, Postgres, Bun test
-
----
-
-### Task 1: Codify The Contract In The Owning Spec
-
-**Files:**
-
-- Modify: `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
-- Modify: `apps/server/README.md`
-
-**Step 1: Update the normative Session Security text**
-
-Add the approved throttling contract under the existing Session Security section:
-
-```md
-- Failed password login attempts apply exponential backoff keyed by normalized email.
-- Active backoff rejects password-entry requests with `AUTH_BACKOFF_ACTIVE` (`429`) and `Retry-After`.
-- Successful password sign-in resets the stored backoff state.
-```
-
-**Step 2: Update the auth endpoint table**
-
-Modify the deterministic error column for:
-
-- `POST /api/v1/auth/login`
-- `POST /api/v1/auth/cli/login/authorize`
-
-so the table includes `AUTH_BACKOFF_ACTIVE` (`429`) in addition to `AUTH_INVALID_CREDENTIALS` (`401)`.
-
-**Step 3: Add the operator-facing server README note**
-
-Document:
-
-- which routes are protected
-- that `Retry-After` is emitted on active backoff
-- that Better Auth rate limiting is not relied on for this contract
-
-**Step 4: Verify the spec delta against CMS-39 acceptance**
-
-Confirm these exact points are present before code changes:
-
-- observable backoff via `429`
-- deterministic error code `AUTH_BACKOFF_ACTIVE`
-- protected flows limited to password-entry routes
-- reset rules: success and quiet-window expiry
-
-**Step 5: Commit the docs checkpoint if using commit gates**
-
-```bash
-git add docs/specs/SPEC-005-auth-authorization-and-request-routing.md apps/server/README.md
-git commit -m "docs: define login backoff contract"
-```
-
-### Task 2: Add Schema Coverage For Persisted Throttle State
-
-**Files:**
-
-- Modify: `apps/server/src/lib/db/schema.ts`
-- Create: `apps/server/drizzle/0008_<name>.sql`
-- Modify: `apps/server/drizzle/meta/_journal.json`
-- Create: `apps/server/drizzle/meta/0008_snapshot.json`
-- Modify: `apps/server/src/lib/db/schema.contract.test.ts`
-
-**Step 1: Add the new Drizzle table definition**
-
-Add a table like:
-
-```ts
-export const authLoginBackoffs = pgTable(
-  "auth_login_backoffs",
-  {
-    id: uuid().defaultRandom().primaryKey(),
-    loginKey: text().notNull(),
-    failureCount: integer().notNull().default(0),
-    firstFailedAt: timestamp({ withTimezone: true }).notNull(),
-    lastFailedAt: timestamp({ withTimezone: true }).notNull(),
-    nextAllowedAt: timestamp({ withTimezone: true }).notNull(),
-    createdAt: timestamp({ withTimezone: true }).defaultNow().notNull(),
-    updatedAt: timestamp({ withTimezone: true }).defaultNow().notNull(),
-  },
-  (table) => [
-    unique("uniq_auth_login_backoffs_login_key").on(table.loginKey),
-    index("idx_auth_login_backoffs_next_allowed").on(table.nextAllowedAt),
-  ],
-);
-```
-
-If the team prefers no surrogate `id`, use `loginKey` as the primary key instead, but keep the final schema and migration aligned.
-
-**Step 2: Write the SQL migration and snapshot**
-
-Create the migration that adds `auth_login_backoffs` plus the required named index/constraint, then update the journal and latest snapshot under `apps/server/drizzle/meta/`.
-
-**Step 3: Extend the schema contract test**
-
-Add `public.auth_login_backoffs` to the expected tables and assert the named unique/index entries:
-
-```ts
-"public.auth_login_backoffs": [
-  "id",
-  "login_key",
-  "failure_count",
-  "first_failed_at",
-  "last_failed_at",
-  "next_allowed_at",
-  "created_at",
-  "updated_at",
-]
-```
-
-**Step 4: Run the schema contract test**
-
-Run: `bun test apps/server/src/lib/db/schema.contract.test.ts`
-
-Expected: FAIL until the new table, migration artifacts, and snapshot assertions all match.
-
-**Step 5: Commit the schema checkpoint**
-
-```bash
-git add apps/server/src/lib/db/schema.ts apps/server/drizzle apps/server/src/lib/db/schema.contract.test.ts
-git commit -m "feat(server): add persisted login backoff table"
-```
-
-### Task 3: Add Red Auth Tests For Backoff Semantics
-
-**Files:**
-
-- Modify: `apps/server/src/lib/auth.test.ts`
-
-**Step 1: Add clock-control helpers for auth throttling tests**
-
-Prefer a narrow helper local to this test file:
-
-```ts
-async function withMockedNow<T>(
-  value: number,
-  run: () => Promise<T>,
-): Promise<T> {
-  const originalNow = Date.now;
-  Date.now = () => value;
-  try {
-    return await run();
-  } finally {
-    Date.now = originalNow;
-  }
-}
-```
-
-If `auth.ts` already accepts a clock dependency by the time you implement this, use that instead of monkey-patching.
-
-**Step 2: Add failing tests for direct login**
-
-Add tests that prove:
-
-- first invalid password attempt returns `401 AUTH_INVALID_CREDENTIALS`
-- immediate retry returns `429 AUTH_BACKOFF_ACTIVE`
-- `Retry-After` reflects the stored delay
-- advancing beyond the delay allows another credential check
-- successful login clears the backoff row
-
-Example assertion shape:
-
-```ts
-assert.equal(response.status, 429);
-assert.equal(body.error.code, "AUTH_BACKOFF_ACTIVE");
-assert.equal(response.headers.get("retry-after"), "1");
-```
-
-**Step 3: Add failing tests for CLI authorize**
-
-Cover the credential-submission branch of `POST /api/v1/auth/cli/login/authorize`:
-
-- invalid credentials return `401`
-- immediate retry while locked returns `429`
-- active lockout does not mutate the challenge into an authorized state
-
-**Step 4: Run the focused auth suite**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-
-Expected: FAIL on the new throttling assertions because no backoff state exists yet.
-
-**Step 5: Commit the red-test checkpoint**
-
-```bash
-git add apps/server/src/lib/auth.test.ts
-git commit -m "test(server): add CMS-39 login backoff coverage"
-```
-
-### Task 4: Implement Shared Login Backoff Helpers
-
-**Files:**
-
-- Modify: `apps/server/src/lib/auth.ts`
-
-**Step 1: Add constants and helper functions near the auth constants**
-
-Add small, explicit constants:
-
-```ts
-const LOGIN_BACKOFF_RESET_WINDOW_MS = 15 * 60 * 1000;
-const LOGIN_BACKOFF_DELAYS_SECONDS = [1, 2, 4, 8, 16, 32] as const;
-```
-
-Add helpers for:
-
-- normalizing email to a throttle key
-- reading the current backoff row
-- deciding whether the row has expired into a fresh window
-- computing the next delay
-- computing `Retry-After`
-- upserting failure state
-- clearing state on success
-
-**Step 2: Add a deterministic runtime error for active backoff**
-
-Throw a `RuntimeError` like:
-
-```ts
-throw new RuntimeError({
-  code: "AUTH_BACKOFF_ACTIVE",
-  message: `Too many failed login attempts. Retry after ${retryAfterSeconds} seconds.`,
-  statusCode: 429,
-});
-```
-
-Keep the header emission path separate so the response also includes:
-
-```ts
-{ "retry-after": String(retryAfterSeconds) }
-```
-
-**Step 3: Route password login through the helper flow**
-
-Refactor `loginWithEmailPassword(...)` so it:
-
-1. normalizes the email
-2. checks for active backoff before calling Better Auth
-3. calls `auth.api.signInEmail(...)`
-4. on invalid credentials, records the next backoff state and rethrows `AUTH_INVALID_CREDENTIALS`
-5. on success, clears the backoff row before returning the session data
-
-Avoid changing unrelated session, CSRF, API key, or SSO behavior.
-
-**Step 4: Re-run the focused auth suite**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-
-Expected: the direct-login throttling tests now pass; any remaining failures should be limited to route-response header plumbing or CLI-path integration.
-
-**Step 5: Commit the helper implementation**
-
-```bash
-git add apps/server/src/lib/auth.ts
-git commit -m "feat(server): add shared login backoff helpers"
-```
-
-### Task 5: Surface `429` Headers On Both Password Routes
-
-**Files:**
-
-- Modify: `apps/server/src/lib/auth.ts`
-
-**Step 1: Extend the auth service result shape if needed**
-
-If `loginWithEmailPassword(...)` needs to return metadata for callers, keep it minimal:
-
-```ts
-type LoginResult = {
-  session: StudioSession;
-  setCookie: string;
-};
-```
-
-For throttled requests, prefer central runtime-error handling with support for extra response headers rather than returning unions from every auth path.
-
-**Step 2: Ensure `executeWithRuntimeErrorsHandled(...)` can emit `Retry-After`**
-
-If the runtime error handler already supports extra headers, reuse that. If not, extend the smallest shared error path so a `RuntimeError` can carry response headers without changing unrelated API behavior.
-
-**Step 3: Verify both routes now share the same throttle behavior**
-
-Confirm:
-
-- `POST /api/v1/auth/login`
-- password-backed `POST /api/v1/auth/cli/login/authorize`
-
-both return `429 AUTH_BACKOFF_ACTIVE` with `Retry-After` when blocked.
-
-**Step 4: Run auth tests again**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-
-Expected: PASS
-
-**Step 5: Commit the response-plumbing checkpoint**
-
-```bash
-git add apps/server/src/lib/auth.ts
-git commit -m "feat(server): return retry-after for throttled logins"
-```
-
-### Task 6: Finish Docs, Formatting, And Validation
-
-**Files:**
-
-- Modify: `apps/server/README.md`
-- Modify: `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
-- Modify: `apps/server/src/lib/auth.ts`
-- Modify: `apps/server/src/lib/auth.test.ts`
-- Modify: `apps/server/src/lib/db/schema.ts`
-- Modify: `apps/server/src/lib/db/schema.contract.test.ts`
-- Modify: `apps/server/drizzle/...`
-
-**Step 1: Add the point-of-use code comment**
-
-Place one short comment near the throttling helper in `auth.ts` explaining:
-
-```ts
-// MDCMS owns failed-attempt backoff here because server-side auth.api calls are outside Better Auth's built-in rate limiter.
-```
-
-**Step 2: Run the focused verification commands**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/auth.test.ts
-bun test apps/server/src/lib/db/schema.contract.test.ts
-```
-
-Expected: PASS
-
-**Step 3: Run workspace-level verification**
-
-Run:
-
-```bash
-bun run format:check
-bun run check
-```
-
-Expected: PASS
-
-If `bun run check` is too broad for local-only blockers unrelated to this task, capture the exact failure and stop before claiming success.
-
-**Step 4: Inspect git status for task scope hygiene**
-
-Run:
-
-```bash
-git status --short
-```
-
-Confirm:
-
-- only `CMS-39`-relevant tracked files are modified
-- local-only paths such as `docs/plans/`, `AGENTS.md`, `ROADMAP_TASKS.md`, `.claude/`, and `.codex/` are not staged
-
-**Step 5: Commit the final task-scoped implementation**
-
-```bash
-git add docs/specs/SPEC-005-auth-authorization-and-request-routing.md apps/server/README.md apps/server/src/lib/auth.ts apps/server/src/lib/auth.test.ts apps/server/src/lib/db/schema.ts apps/server/src/lib/db/schema.contract.test.ts apps/server/drizzle
-git commit -m "feat(server): implement login backoff throttling"

-# CMS-33 Design
-
-Date: 2026-03-14
-Task: CMS-33 - Implement server module bootstrap + manifest/dependency/collision validation
-
-## Context
-
-Roadmap source:
-
-- `ROADMAP_TASKS.md` CMS-33
-
-Owning spec:
-
-- `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
-
-Relevant upstream tasks:
-
-- CMS-9 shared extensibility contracts
-- CMS-10 unified module topology
-- CMS-13 scoped content DAL helpers
-
-Relevant downstream tasks:
-
-- CMS-34 action registry + action catalog + Studio bootstrap endpoints
-- CMS-35 extensibility contract validation suite
-
-## Spec Delta Summary
-
-No new spec file changes were present in the workspace. CMS-33 is already specified by the owning spec and roadmap.
-
-The clarified contract for this task is:
-
-- server startup validates a full module dependency graph
-- missing `dependsOn` targets fail startup before route registration
-- dependency cycles fail startup
-- startup emits one deterministic aggregated validation report instead of stopping at the first violation
-- explicit composition-root dependency wiring remains required; no DI container or service locator runtime patterns are introduced
-
-## Chosen Approach
-
-Chosen approach: replace the permissive shared module loader path with a strict shared bootstrap pipeline used by both server and CLI internals, while anchoring the user-visible acceptance behavior to server startup.
-
-Why this approach:
-
-- it is the cleanest long-term architecture
-- it prevents server and CLI from diverging on dependency ordering and validation semantics
-- it keeps the hard logic in `@mdcms/shared`, which CMS-34 and CMS-35 can reuse directly
-
-## Architecture
-
-The current shared loader/report path is permissive: invalid or incompatible modules become "skipped" entries. CMS-33 requires fail-fast startup validation, so the shared runtime layer becomes the source of truth for strict bootstrap planning.
-
-The shared bootstrap pipeline will:
-
-1. Validate module package shape and manifest compatibility.
-2. Index modules by `manifest.id`.
-3. Detect duplicate module IDs.
-4. Validate dependency existence for `dependsOn`.
-5. Detect dependency cycles.
-6. Compute deterministic topological order, using `manifest.id` as the stable tie-breaker.
-7. Project the ordered module graph into runtime-specific plans.
-8. Validate runtime-surface collisions, including duplicate server `action.id`.
-9. Return either a deterministic ordered plan or a deterministic aggregated bootstrap failure.
-
-Server and CLI loaders become thin wrappers over the shared strict planner.
-
-Server-specific behavior for CMS-33:
-
-- startup throws before action collection
-- startup throws before module route registration
-- mounted modules continue to receive explicitly assembled dependencies from the composition root
-
-CLI behavior in this task:
-
-- consume the same strict planner for ordering and internal consistency
-- avoid changing CLI operator-facing semantics unless the refactor makes a small documentation update necessary
-
-## Failure Model
-
-Bootstrap violations are collected into one deterministic failure payload with:
-
-- one stable top-level runtime error code
-- a stable, sorted list of violation entries
-- machine-usable `details` for unit and integration tests
-
-Violation kinds expected in scope:
-
-- `INVALID_PACKAGE`
-- `INCOMPATIBLE_MANIFEST`
-- `DUPLICATE_MODULE_ID`
-- `MISSING_DEPENDENCY`
-- `DEPENDENCY_CYCLE`
-- `DUPLICATE_ACTION_ID`
-
-Missing runtime surface is not treated as a bootstrap failure by itself. It only means that a module does not participate in that runtime.
-
-## Files In Scope
-
-Shared runtime core:
-
-- `packages/shared/src/lib/runtime/module-loader-core.ts`
-- `packages/shared/src/lib/runtime/module-loader-core.test.ts`
-- `packages/shared/src/lib/runtime/index.ts`
-- `packages/shared/README.md`
-
-Server integration:
-
-- `apps/server/src/lib/module-loader.ts`
-- `apps/server/src/lib/module-loader.test.ts`
-- `apps/server/src/lib/runtime-with-modules.ts`
-- `apps/server/src/lib/runtime-with-modules.test.ts`
-- `apps/server/README.md`
-
-CLI internal alignment:
-
-- `apps/cli/src/lib/module-loader.ts`
-- `apps/cli/src/lib/module-loader.test.ts`
-- `apps/cli/src/lib/runtime-with-modules.ts`
-
-## Test Strategy
-
-Shared unit coverage:
-
-- duplicate module IDs
-- missing dependencies
-- dependency cycle detection
-- deterministic topological ordering
-- duplicate server action IDs
-- deterministic aggregation and sorting of bootstrap errors
-
-Server integration coverage:
-
-- invalid graph fails before route registration
-- duplicate action IDs fail before action collection
-- explicit dependency wiring is still passed through `mount(app, deps)`
-
-CLI regression coverage:
-
-- deterministic ordering still holds through the new shared bootstrap pipeline
-- runtime-specific extraction still returns expected aliases/formatters/hooks
-
-## Documentation
-
-Document at point of use:
-
-- shared README describes the strict bootstrap planner and deterministic failure semantics
-- server README states that module bootstrap now fails startup on manifest, dependency, cycle, and action ID collisions
-
-## Constraints
-
-- `docs/plans/` is local-only in this repository and must remain untracked
-- user explicitly requested staying in the main workdir instead of creating a worktree

-# CMS-33 Strict Module Bootstrap Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Replace permissive module loading with a strict shared bootstrap pipeline and make server startup fail fast on manifest, dependency, cycle, compatibility, and action ID violations before any module routes are registered.
-
-**Architecture:** Build a runtime-agnostic bootstrap planner in `@mdcms/shared` that validates module packages, computes deterministic dependency ordering, and returns either an ordered runtime plan or an aggregated bootstrap failure. Refactor server and CLI loaders to consume that planner; activate fail-fast startup semantics in the server while preserving explicit composition-root dependency wiring.
-
-**Tech Stack:** Bun, Nx, TypeScript, node:test, Zod, Elysia
-
----
-
-### Task 1: Replace permissive shared load reports with a strict bootstrap planner
-
-**Files:**
-
-- Modify: `packages/shared/src/lib/runtime/module-loader-core.ts`
-- Modify: `packages/shared/src/lib/runtime/module-loader-core.test.ts`
-- Modify: `packages/shared/src/lib/runtime/index.ts`
-- Test: `packages/shared/src/lib/runtime/module-loader-core.test.ts`
-
-**Step 1: Write the failing shared bootstrap tests**
-
-Add tests to `packages/shared/src/lib/runtime/module-loader-core.test.ts` for:
-
-- duplicate `manifest.id`
-- missing `dependsOn`
-- dependency cycle detection
-- deterministic topological ordering with `manifest.id` tie-breaking
-- duplicate server `action.id`
-- deterministic aggregated violation ordering
-
-Use helpers like:
-
-```ts
-const alpha = createModule("alpha", {
-  server: true,
-  dependsOn: ["core.system"],
-});
-
-const beta = createModule("beta", {
-  server: true,
-  dependsOn: ["alpha"],
-});
-
-const plan = buildRuntimeModulePlan([beta, alpha, coreSystem], {
-  coreVersion: "1.0.0",
-  runtime: "server",
-  surface: "server",
-  logger: createNoopLogger(),
-});
-
-assert.equal(plan.ok, true);
-assert.deepEqual(plan.moduleIds, ["core.system", "alpha", "beta"]);
-```
-
-And failing cases like:
-
-```ts
-const plan = buildRuntimeModulePlan([a, b], {
-  coreVersion: "1.0.0",
-  runtime: "server",
-  surface: "server",
-  logger: createNoopLogger(),
-});
-
-assert.equal(plan.ok, false);
-assert.deepEqual(
-  plan.violations.map((entry) => entry.code),
-  ["DUPLICATE_MODULE_ID"],
-);
-```
-
-**Step 2: Run the shared test file to verify it fails**
-
-Run:
-
-```bash
-bun test packages/shared/src/lib/runtime/module-loader-core.test.ts
-```
-
-Expected: FAIL because `buildRuntimeModulePlan(...)` and strict bootstrap semantics do not exist yet.
-
-**Step 3: Implement the strict shared planner**
-
-In `packages/shared/src/lib/runtime/module-loader-core.ts`, replace the skip-oriented model with planner-first types and logic such as:
-
-```ts
-export type ModuleBootstrapViolationCode =
-  | "INVALID_PACKAGE"
-  | "INCOMPATIBLE_MANIFEST"
-  | "DUPLICATE_MODULE_ID"
-  | "MISSING_DEPENDENCY"
-  | "DEPENDENCY_CYCLE"
-  | "DUPLICATE_ACTION_ID";
-
-export type ModuleBootstrapViolation = {
-  code: ModuleBootstrapViolationCode;
-  moduleId: string;
-  details: string;
-};
-
-export type RuntimeModulePlan<TSurface extends ModuleSurface> =
-  | {
-      ok: true;
-      moduleIds: readonly string[];
-      loaded: readonly LoadedModule<TSurface>[];
-    }
-  | {
-      ok: false;
-      violations: readonly ModuleBootstrapViolation[];
-    };
-```
-
-Implementation rules:
-
-- validate package shape and manifest compatibility first
-- collect duplicate module IDs before graph traversal
-- validate every `dependsOn` target exists
-- detect cycles with DFS or Kahn-based cycle detection
-- compute deterministic topological ordering using `manifest.id` as tie-breaker
-- filter to modules exposing the requested runtime surface
-- validate duplicate server `action.id` after ordering
-- sort violations deterministically by code, then module ID, then details
-
-Export the planner from `packages/shared/src/lib/runtime/index.ts`.
-
-**Step 4: Re-run the shared test file**
-
-Run:
-
-```bash
-bun test packages/shared/src/lib/runtime/module-loader-core.test.ts
-```
-
-Expected: PASS.
-
-**Step 5: Commit the shared bootstrap planner**
-
-```bash
-git add packages/shared/src/lib/runtime/module-loader-core.ts packages/shared/src/lib/runtime/module-loader-core.test.ts packages/shared/src/lib/runtime/index.ts
-git commit -m "refactor(shared): add strict module bootstrap planner"
-```

-- Modify: `apps/server/src/lib/module-loader.ts`
-- Modify: `apps/server/src/lib/module-loader.test.ts`

-- Test: `apps/server/src/lib/runtime-with-modules.test.ts`
-
-**Step 1: Write failing server tests**
-
-Update server tests to assert:
-
-- duplicate action IDs cause startup failure
-- missing dependency targets cause startup failure
-- failures happen before `mountLoadedServerModules(...)`
-- explicit deps are still passed into `mount(app, deps)`
-
-Add a mount-guard test like:
-
-```ts
-let mounted = false;
-
-const invalid = createServerModule("broken", {
-  dependsOn: ["missing.core"],
-  onMount: () => {
-    mounted = true;
-  },
-});

-assert.throws(
-  () =>
-    createServerRequestHandlerWithModules({

-```bash
-bun test apps/server/src/lib/module-loader.test.ts apps/server/src/lib/runtime-with-modules.test.ts
-```
-
-Expected: FAIL because server code still treats invalid or incompatible modules as skip/report data instead of throwing before startup proceeds.
-
-**Step 3: Implement strict server bootstrap consumption**
-
-In `apps/server/src/lib/module-loader.ts`:
-
-- replace `buildServerModuleLoadReport(...)` internals to call the shared strict planner
-- return a validated ordered plan for server modules
-- throw one `RuntimeError` for bootstrap failures with a stable top-level code such as `INVALID_MODULE_BOOTSTRAP`
-
-In `apps/server/src/lib/runtime-with-modules.ts`:
-
-- build the server module plan before collecting actions
-- build the plan before mounting routes
-- keep `moduleDeps` explicit and continue passing them directly into each module `mount`
-
-Shape the failure like:
-
-```ts
-throw new RuntimeError({
-  code: "INVALID_MODULE_BOOTSTRAP",
-  message: "Server module bootstrap failed.",
-  statusCode: 500,
-  details: {
-    violations,
-  },
-});
-```
-
-**Step 4: Re-run the server loader tests**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/module-loader.test.ts apps/server/src/lib/runtime-with-modules.test.ts
-```
-
-Expected: PASS.
-
-**Step 5: Commit the server fail-fast refactor**
-
-```bash
-git add apps/server/src/lib/module-loader.ts apps/server/src/lib/module-loader.test.ts apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/runtime-with-modules.test.ts
-git commit -m "feat(server): fail fast on invalid module bootstrap"
-```
-
-### Task 3: Move CLI loaders onto the same strict ordered planner
-
-**Files:**
-
-- Modify: `apps/cli/src/lib/module-loader.ts`
-- Modify: `apps/cli/src/lib/module-loader.test.ts`
-- Modify: `apps/cli/src/lib/runtime-with-modules.ts`
-- Test: `apps/cli/src/lib/module-loader.test.ts`
-
-**Step 1: Write failing CLI tests around the new shared semantics**
-
-Adjust CLI tests so they assert:
-
-- deterministic ordered module IDs still hold under the strict planner
-- aliases, output formatters, and preflight hooks are collected from ordered loaded CLI modules
-- invalid-package or missing-dependency planner failures surface predictably if the CLI wrapper receives an invalid candidate set
-
-**Step 2: Run the CLI loader test to verify it fails**
-
-Run:
-
-```bash
-bun test apps/cli/src/lib/module-loader.test.ts
-```
-
-Expected: FAIL because the CLI loader still depends on the old skip-report shape.
-
-**Step 3: Refactor CLI loaders to consume the shared planner**
-
-In `apps/cli/src/lib/module-loader.ts` and `apps/cli/src/lib/runtime-with-modules.ts`:
-
-- swap old report-builder usage for the strict shared planner
-- keep the runtime-specific extraction for aliases, output formatters, and preflight hooks
-- preserve existing CLI runtime shape as much as possible so CMS-33 does not become a CLI behavior task
-
-**Step 4: Re-run the CLI loader test**
-
-Run:
-
-```bash
-bun test apps/cli/src/lib/module-loader.test.ts
-```
-
-Expected: PASS.
-
-**Step 5: Commit the CLI planner alignment**
-
-```bash
-git add apps/cli/src/lib/module-loader.ts apps/cli/src/lib/module-loader.test.ts apps/cli/src/lib/runtime-with-modules.ts
-git commit -m "refactor(cli): align module bootstrap with shared planner"
-```
-
-### Task 4: Update documentation and verify the full task scope
-
-**Files:**
-
-- Modify: `packages/shared/README.md`
-- Modify: `apps/server/README.md`
-- Test: `packages/shared/src/lib/runtime/module-loader-core.test.ts`
-- Test: `apps/server/src/lib/module-loader.test.ts`
-- Test: `apps/server/src/lib/runtime-with-modules.test.ts`
-- Test: `apps/cli/src/lib/module-loader.test.ts`
-
-**Step 1: Update point-of-use docs**
-
-Document:
-
-- the strict bootstrap planner and deterministic violation model in `packages/shared/README.md`
-- server startup fail-fast semantics in `apps/server/README.md`
-
-Keep CLI README changes minimal unless a user-facing behavior description actually changes.
-
-**Step 2: Run focused tests**
-
-Run:
-
-```bash
-bun test packages/shared/src/lib/runtime/module-loader-core.test.ts
-bun test apps/server/src/lib/module-loader.test.ts apps/server/src/lib/runtime-with-modules.test.ts
-bun test apps/cli/src/lib/module-loader.test.ts
-```
-
-Expected: PASS.
-
-**Step 3: Run required repo checks**
-
-Run:
-
-```bash
-bun run format:check
-bun run check
-```
-
-Expected: PASS.
-
-**Step 4: Review git status for task scope hygiene**
-
-Run:
-
-```bash
-git status --short
-```
-
-Expected:
-
-- only CMS-33 code/docs changes are staged
-- local-only paths remain unstaged and uncommitted, including `docs/plans/`
-
-**Step 5: Commit the docs and verification pass**
-
-```bash
-git add packages/shared/README.md apps/server/README.md
-git commit -m "docs: record strict module bootstrap behavior"
-```

-# CMS-34 Action Catalog and Studio Bootstrap Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Publish the canonical module action catalog and the MVP `module`-mode Studio bootstrap/runtime asset endpoints from the server without pulling loader execution work forward from CMS-60.
-
-**Architecture:** Extend the existing server request-handler composition so it publishes two canonical backend contracts from startup-prepared data: a deterministic filtered action registry and a cached Studio runtime publication snapshot. Keep shared contract validation in `@mdcms/shared`, artifact generation in `@mdcms/studio`, and HTTP publication/error handling in `@mdcms/server`.
-
-**Tech Stack:** Bun, Nx, TypeScript, node:test, Elysia, Zod, filesystem APIs

-### Task 1: Add a server-owned Studio runtime publication helper
-
-**Files:**
-
-- Create: `apps/server/src/lib/studio-bootstrap.ts`
-- Create: `apps/server/src/lib/studio-bootstrap.test.ts`
-- Modify: `apps/server/src/index.ts`
-- Modify: `apps/server/package.json`
-- Test: `apps/server/src/lib/studio-bootstrap.test.ts`
-
-**Step 1: Write the failing publication-helper tests**
-
-Add tests to `apps/server/src/lib/studio-bootstrap.test.ts` for:
-
-- building one validated `StudioBootstrapManifest`
-- returning `mode: "module"` in the manifest
-- resolving the active `buildId` and asset root
-- returning asset metadata for an existing runtime file
-- returning `undefined` for an unknown `buildId` or missing asset path
-
-Use a temp directory and a tiny fixture source file so the helper can call the real Studio artifact builder. Model the assertions like:
-
-```ts
-const publication = await createStudioRuntimePublication({
-  sourceFile,
-  outDir,
-  studioVersion: "1.2.3",
-});
-
-assert.equal(publication.manifest.mode, "module");
-assert.equal(publication.manifest.buildId, publication.buildId);
-
-const asset = await publication.getAsset({
-  buildId: publication.buildId,
-  assetPath: publication.entryFile,
-});
-
-assert.equal(asset?.contentType, "text/javascript; charset=utf-8");
-assert.equal(asset?.absolutePath.endsWith(publication.entryFile), true);
-```
-
-**Step 2: Run the new publication-helper test file**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/studio-bootstrap.test.ts
-```
-
-Expected: FAIL because the helper does not exist yet.
-
-**Step 3: Implement the publication helper**
-
-Create `apps/server/src/lib/studio-bootstrap.ts` with a small server-owned abstraction around `buildStudioRuntimeArtifacts(...)`, for example:
-
-```ts
-export type StudioRuntimePublication = {
-  buildId: string;
-  entryFile: string;
-  manifest: StudioBootstrapManifest;
-  getAsset: (input: {
-    buildId: string;
-    assetPath: string;
-  }) => Promise<StudioRuntimeAsset | undefined>;
-};
-```
-
-Implementation rules:
-
-- call `buildStudioRuntimeArtifacts(...)` once
-- force `mode: "module"` unless a future spec changes this task contract
-- validate `manifest` with shared validators before returning
-- normalize asset paths so callers cannot escape the active build root
-- return `undefined` instead of throwing for unknown build IDs or missing files
-
-Also:
-
-- export the helper from `apps/server/src/index.ts`
-- add `@mdcms/studio` as a workspace dependency in `apps/server/package.json`
-
-**Step 4: Re-run the publication-helper test file**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/studio-bootstrap.test.ts
-```
-
-Expected: PASS.
-
-**Step 5: Commit the publication helper**
-
-```bash
-git add apps/server/src/lib/studio-bootstrap.ts apps/server/src/lib/studio-bootstrap.test.ts apps/server/src/index.ts apps/server/package.json
-git commit -m "feat(server): add studio runtime publication helper"
-```
-
-### Task 2: Expose `/api/v1/studio/bootstrap` and `/api/v1/studio/assets/:buildId/*` from the shared server handler
-
-**Files:**
-
-- Modify: `apps/server/src/lib/server.ts`
-- Modify: `apps/server/src/lib/http-utils.ts`
-- Modify: `apps/server/src/lib/health.test.ts`
-- Test: `apps/server/src/lib/health.test.ts`
-
-**Step 1: Write the failing server contract tests**
-
-Extend `apps/server/src/lib/health.test.ts` with tests for:
-
-- `GET /api/v1/studio/bootstrap` returns `200` with the prepared manifest
-- `GET /api/v1/studio/assets/:buildId/*` returns the expected JavaScript bytes and content type
-- unknown `buildId` returns a `404 NOT_FOUND` envelope
-- missing asset under a known build returns a `404 NOT_FOUND` envelope
-
-Use a stubbed publication object so the tests stay fast and isolated:
-
-```ts
-const handler = createServerRequestHandler({
-  env: baseEnv,
-  studioRuntimePublication: {
-    manifest,
-    buildId: "abc123",
-    entryFile: "studio-runtime.abc123.mjs",
-    getAsset: async ({ buildId, assetPath }) =>
-      buildId === "abc123" && assetPath === "studio-runtime.abc123.mjs"
-        ? {
-            body: "export const marker = 'runtime';\n",
-            contentType: "text/javascript; charset=utf-8",
-          }
-        : undefined,
-  },
-});
-```
-
-**Step 2: Run the shared server contract tests**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/health.test.ts
-```
-
-Expected: FAIL because `createServerRequestHandler(...)` does not support Studio runtime publication routes yet.
-
-**Step 3: Implement Studio publication routes in the server handler**
-
-Modify `apps/server/src/lib/server.ts` to accept a new option such as:
-
-```ts
-studioRuntimePublication?: StudioRuntimePublication;
-```
-
-Then:
-
-- mount `GET /api/v1/studio/bootstrap`
-- mount `GET /api/v1/studio/assets/:buildId/*`
-- return plain asset responses for successful asset requests
-- convert missing publication or missing files into the standard `NOT_FOUND` server envelope
-
-Use helper functions in `apps/server/src/lib/http-utils.ts` to create non-JSON responses cleanly, for example:
-
-```ts
-export function createTextResponse(
-  body: string,
-  statusCode: number,
-  contentType: string,
-): Response;
-```
-
-Implementation rules:
-
-- keep `/api/v1` as the only supported base path
-- keep action catalog behavior unchanged
-- keep bootstrap and asset routes public per spec
-- keep error normalization inside the existing handler flow
-
-**Step 4: Re-run the server contract tests**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/health.test.ts
-```
-
-Expected: PASS.
-
-**Step 5: Commit the server route publication work**
-
-```bash
-git add apps/server/src/lib/server.ts apps/server/src/lib/http-utils.ts apps/server/src/lib/health.test.ts
-git commit -m "feat(server): publish studio bootstrap endpoints"
-```
-
-### Task 3: Wire module runtime composition to publish actions and Studio runtime together
-
-**Files:**
-
-- Modify: `apps/server/src/lib/runtime-with-modules.ts`
-- Modify: `apps/server/src/lib/runtime-with-modules.test.ts`
-- Test: `apps/server/src/lib/runtime-with-modules.test.ts`
-
-**Step 1: Write the failing integration tests**
-
-Extend `apps/server/src/lib/runtime-with-modules.test.ts` so it verifies:
-
-- bundled module actions still appear at `GET /api/v1/actions`
-- bundled module probe routes still return `200`
-- `GET /api/v1/studio/bootstrap` returns a validated manifest from the composed runtime
-- `GET /api/v1/studio/assets/:buildId/<entryFile>` returns `200`
-
-Inject a temp output directory into the runtime setup so the test does not depend on repo-global artifact paths.
-
-**Step 2: Run the runtime integration tests**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/runtime-with-modules.test.ts
-```
-
-Expected: FAIL because the composed runtime does not prepare or pass a Studio publication snapshot yet.
-
-**Step 3: Implement startup publication wiring**
-
-Modify `apps/server/src/lib/runtime-with-modules.ts` to:
-
-- build the Studio runtime publication snapshot during server startup
-- pass that snapshot into `createServerRequestHandler(...)`
-- keep module action collection and route mounting behavior intact
-
-Recommended shape:
-
-```ts
-const studioRuntimePublication =
-  awaitOrBuildStudioRuntimePublication(...);
-
-const handler = createServerRequestHandler({
-  ...,
-  actions,
-  studioRuntimePublication,
-  configureApp: (app) => {
-    mountLoadedServerModules(app, moduleDeps, moduleLoadReport);
-  },
-});
-```
-
-If the current constructor shape is synchronous, refactor only as much as needed to prepare the publication snapshot without widening scope beyond this task. Prefer explicit inputs such as optional `studioRuntimePublication` or `studioRuntimeOptions` over hidden global state.
-
-**Step 4: Re-run the runtime integration tests**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/runtime-with-modules.test.ts
-```
-
-Expected: PASS.
-
-**Step 5: Commit the runtime composition wiring**
-
-```bash
-git add apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/runtime-with-modules.test.ts
-git commit -m "feat(server): compose module actions with studio publication"
-```
-
-### Task 4: Document the new contracts and run workspace verification
-
-**Files:**
-
-- Modify: `apps/server/README.md`
-- Modify: `packages/studio/README.md`
-
-**Step 1: Update point-of-use documentation**
-
-Document in `apps/server/README.md`:
-
-- `GET /api/v1/studio/bootstrap`
-- `GET /api/v1/studio/assets/:buildId/*`
-- immutable `buildId` asset semantics
-- MVP bootstrap mode fixed to `module`
-
-Document in `packages/studio/README.md`:
-
-- runtime artifacts are built in `@mdcms/studio`
-- publication now happens from `@mdcms/server`
-- loader execution/verification remains deferred to CMS-60
-
-**Step 2: Run focused tests**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/studio-bootstrap.test.ts apps/server/src/lib/health.test.ts apps/server/src/lib/runtime-with-modules.test.ts
-```
-
-Expected: PASS.
-
-**Step 3: Run format and workspace checks**
-
-Run:
-
-```bash
-bun run format:check
-bun run check
-```
-
-Expected: PASS.
-
-**Step 4: Review git status**
-
-Run:
-
-```bash
-git status --short
-```
-
-Expected:
-
-- only task-scoped source/doc changes are staged or ready to stage
-- local-only paths such as `docs/plans/`, `AGENTS.md`, `ROADMAP_TASKS.md`, `.claude/`, and `.codex/` remain unstaged and uncommitted
-
-**Step 5: Commit the docs and final task slice**
-
-```bash
-git add apps/server/README.md packages/studio/README.md
-git commit -m "docs: publish cms-34 runtime contract notes"
-```

-# CMS-34 Design
-
-Date: 2026-03-14
-Task: CMS-34 - Implement action registry + action catalog + Studio bootstrap endpoints
-
-## Context
-
-Roadmap source:
-
-- `ROADMAP_TASKS.md` CMS-34
-
-Owning specs:
-
-- `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
-- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-- `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
-
-Relevant upstream tasks:
-
-- CMS-5 typed action catalog contract baseline
-- CMS-9 shared extensibility contracts
-- CMS-10 Studio runtime artifact topology
-- CMS-21 content API baseline
-- CMS-33 strict server module bootstrap
-
-Relevant downstream tasks:
-
-- CMS-35 contract validation suite for extensibility
-- CMS-60 `@mdcms/studio` runtime loader + composition surfaces
-
-## Spec Delta Summary
-
-No spec file edits were present in the workspace for this task. During planning, the unresolved Studio execution-mode decision in the owning specs was clarified for MVP execution:
-
-- `/api/v1/studio/bootstrap` must always publish `mode: "module"` in MVP
-- `iframe` mode remains deferred to later spec/task work
-
-That clarification affects the normative Studio bootstrap contract used by `CMS-34` acceptance criteria 1 and 5.
-
-## Chosen Approach
-
-Chosen approach: keep shared contracts as the source of truth, add server-side publication of canonical action and Studio runtime metadata, and avoid introducing loader-side runtime execution work that belongs to CMS-60.
-
-Why this approach:
-
-- it stays inside `CMS-34` scope
-- it builds directly on the existing strict module bootstrap and Studio artifact builder
-- it gives downstream Studio loader work a stable backend contract without inventing extra surfaces
-
-## Architecture
-
-`CMS-34` is primarily a server publication task.
-
-The server already has:
-
-- strict module bootstrap in `apps/server/src/lib/module-loader.ts`
-- action catalog route contract source in `apps/server/src/lib/action-catalog-contract.ts`
-- runtime composition in `apps/server/src/lib/runtime-with-modules.ts`
-- Studio artifact generation in `packages/studio/src/lib/build-runtime.ts`
-
-This task adds a server-owned publication layer with two responsibilities:
-
-1. Derive one deterministic in-memory action registry from mounted server module surfaces.
-2. Derive one deterministic Studio runtime publication snapshot at startup and expose it over HTTP.
-
-Recommended shape:
-
-- keep action metadata validation and ordering in `apps/server/src/lib/server.ts`
-- add a server-side Studio publication helper in a new file such as `apps/server/src/lib/studio-bootstrap.ts`
-- export any new server-owned route contract helpers from `apps/server/src/index.ts`
-- keep runtime artifact generation in `@mdcms/studio`; server depends on that package to publish the built artifact
-
-This keeps ownership clean:
-
-- `@mdcms/shared`: contract types and validators
-- `@mdcms/studio`: runtime artifact builder
-- `@mdcms/server`: HTTP routes, startup publication, filtering, and asset serving
-
-## Data Flow
-
-Server startup flow:
-
-1. Load server modules through the strict bootstrap path.
-2. Collect server actions from the loaded module report.
-3. Validate and sort the action catalog deterministically by `id`.
-4. Build one Studio runtime artifact set using the existing builder, producing:
-   - `manifest`
-   - `buildId`
-   - `entryFile`
-   - `entryPath`
-   - `entryUrl`
-5. Cache that Studio publication snapshot in server memory for request handling.
-
-Request flow:
-
-- `GET /api/v1/actions`
-  - returns the filtered deterministic list of action catalog items
-- `GET /api/v1/actions/:id`
-  - returns one filtered action item or `NOT_FOUND`
-- `GET /api/v1/studio/bootstrap`
-  - returns the cached validated `StudioBootstrapManifest`
-- `GET /api/v1/studio/assets/:buildId/*`
-  - serves only files under the cached immutable artifact root for the current `buildId`
-
-The server should not rebuild the runtime artifact on every request. Publication happens once at startup and request handlers read the prepared snapshot.
-
-## Visibility and Authorization Handling
-
-The current action metadata contract exposes advisory `permissions`, plus optional `studio` and `cli` visibility metadata. It does not define a full executable authorization model for catalog filtering.
-
-For `CMS-34`, the server should keep action visibility filtering injectable and deterministic:
-
-- continue using `isActionVisible` in `createServerRequestHandler(...)`
-- ensure list/detail responses use the same filtering decision
-- avoid adding new action contract fields or embedding executable metadata
-
-This keeps the backend contract aligned with the current spec and leaves stricter policy evolution to later auth/runtime tasks.
-
-## Failure Model
-
-Startup failures:
-
-- invalid action catalog item shape fails startup
-- duplicate action IDs fail startup
-- invalid Studio bootstrap manifest fails startup
-- missing Studio runtime artifact output fails startup
-
-Request failures:
-
-- `/api/v1/actions/:id` returns `404` for missing or filtered actions
-- `/api/v1/studio/bootstrap` returns `404` only when no runtime publication is available
-- `/api/v1/studio/assets/:buildId/*` returns `404` for unknown build IDs or missing files
-
-Error envelopes should remain normalized through existing server error handling.
-
-## Files In Scope
-
-Server runtime:
-
-- `apps/server/src/lib/server.ts`
-- `apps/server/src/lib/runtime-with-modules.ts`
-- `apps/server/src/lib/action-catalog-contract.ts`
-- `apps/server/src/lib/http-utils.ts`
-- `apps/server/src/index.ts`
-
-New server publication helper:
-
-- `apps/server/src/lib/studio-bootstrap.ts`
-- `apps/server/src/lib/studio-bootstrap.test.ts`
-
-Server verification:
-
-- `apps/server/src/lib/health.test.ts`
-- `apps/server/src/lib/runtime-with-modules.test.ts`
-
-Dependency and docs:
-
-- `apps/server/package.json`
-- `apps/server/README.md`
-- `packages/studio/README.md`
-
-## Test Strategy
-
-Server contract tests:
-
-- deterministic ordering for `/api/v1/actions`
-- detail lookup and hidden-action `404` behavior
-- inline request/response schema preservation in catalog payloads
-- `/api/v1/studio/bootstrap` response validates against shared manifest contract
-- bootstrap manifest always reports `mode: "module"`
-- `/api/v1/studio/assets/:buildId/*` serves the expected immutable file for the active build
-- mismatched build IDs and missing asset paths return `404`
-
-Runtime integration tests:
-
-- module probe routes remain mounted and reachable
-- `createServerRequestHandlerWithModules(...)` still surfaces the bundled module actions
-- server startup prepares one runtime publication snapshot and exposes it through the endpoint layer
-
-## Documentation
-
-Document at point of use:
-
-- `apps/server/README.md` should describe the new Studio runtime publication endpoints and deterministic asset semantics
-- `packages/studio/README.md` should note that runtime artifacts are now published by the server while loader execution remains deferred to CMS-60
-
-## Constraints
-
-- `docs/plans/` is local-only in this repository and must remain untracked
-- the brainstorming skill normally wants the design doc committed, but repository policy forbids committing `docs/plans/`
-- no Studio loader/runtime execution work should be pulled forward from CMS-60

-| CMS-36              | Done   |
-
-Conclusion: none of the remaining Week 2 items are currently blocked by the obvious upstream dependencies outside Week 2.
-
-## Recommended Completion Order
-
-### Recommended Single-Thread Sequence
-
-If one team is mainly finishing these serially, this is the cleanest order:
-
-1. CMS-33
-2. CMS-34
-3. CMS-35
-4. CMS-27
-5. CMS-25
-6. CMS-26
-7. CMS-28
-8. CMS-29
-9. CMS-32
-10. CMS-40
-11. CMS-41
-12. CMS-52
-
-### Why This Order
-
-1. **Finish the extensibility chain first (`CMS-33 -> CMS-34 -> CMS-35`).**
-   This is the tightest unfinished dependency chain in Week 2 and it has the highest downstream leverage. `CMS-34` is a platform surface that later Studio and CLI work depends on. Closing this chain early stabilizes module loading, action catalog behavior, and the Studio bootstrap contract before more features stack on top.
-
-2. **Lock the content API contract before adding the remaining behavior (`CMS-27`).**
-   `CMS-27` standardizes the envelope and pagination metadata across content APIs. Doing that early reduces rework in tests and client-facing responses while finishing the rest of content core.
-
-3. **Complete the remaining content behavior in dependency order (`CMS-25`, `CMS-26`, `CMS-28`, `CMS-29`).**
-   `CMS-25` closes the published-vs-draft read semantics. `CMS-26` must land before `CMS-28`. `CMS-29` is independent once the write path exists and should be completed before the content test gate so mismatch protections are covered in the final behavior set.
-
-4. **Run the integration gate only after the content surface is actually stable (`CMS-32`).**
-   Formally, `CMS-32` depends on `CMS-21..CMS-27`. Even so, it is better to schedule it after `CMS-28` and `CMS-29` as well, so the suite reflects the near-final content model and avoids a second round of integration test churn.
-
-5. **Then finish the narrower verticals (`CMS-40 -> CMS-41`, then `CMS-52`).**
-   `CMS-40` and `CMS-41` are a self-contained auth chain with no unresolved upstream blockers. `CMS-52` is also isolated because `CMS-51` is already done. These should follow once the broader platform and content contracts are less likely to shift under them.
-
-## Recommended Parallel Execution Plan
-
-If the team can run multiple tracks at once, this is the better delivery plan:
-
-### Track A: Extensibility Foundation
-
-1. CMS-33
-2. CMS-34
-3. CMS-35
-
-Why:
-
-- Strict dependency chain
-- High downstream fan-out into later Studio and CLI work
-- Best candidate for concentrated ownership by one engineer/pair
-
-### Track B: Content Core Closure
-
-1. CMS-27
-2. CMS-25
-3. CMS-26
-4. CMS-28
-5. CMS-29
-6. CMS-32
-
-Why:
-
-- `CMS-27` locks response contracts first
-- `CMS-26` is needed before `CMS-28`
-- `CMS-32` is the gate and should be last in the track
-
-### Track C: Auth Integrations
-
-1. CMS-40
-2. CMS-41
-
-Why:
-
-- Clean two-step dependency chain
-- No current cross-track blocker after `CMS-36`
-- Can proceed independently while platform/content work continues
-
-### Track D: Editor Completion
-
-1. CMS-52
-
-Why:
-
-- Only depends on `CMS-51`, which is already done
-- Narrow surface area
-- Safe to run in parallel unless editor contract changes are expected from unresolved platform work
-
-## Suggested Near-Term Milestone
-
-The most useful near-term checkpoint is:
-
-1. `CMS-33`, `CMS-34`, `CMS-35` complete
-2. `CMS-27`, `CMS-25`, `CMS-26`, `CMS-28`, `CMS-29` complete
-3. `CMS-32` green and gating
-
-That checkpoint would leave Week 2 with:
-
-- Extensibility closed
-- Content core closed and regression-gated
-- Only the auth integration pair (`CMS-40`, `CMS-41`) and the final editor MDX enhancement (`CMS-52`) still open
-
-## Short Recommendation
-
-If the goal is to reduce future rework, finish the **extensibility chain first**, then close the **remaining content contract and behavior work**, and only after that spend cycles on **OIDC/SAML** and **MDX editor** completion. If the team has parallel capacity, run **OIDC/SAML** and **CMS-52** beside the main platform/content work instead of waiting for them.

-# CMS-27 Response Envelope Design
-
-## Summary
-
-CMS-27 standardizes content API response envelopes and pagination metadata.
-The existing `/api/v1/content` list route already returns the target shape, but
-`GET /api/v1/content/:documentId/versions` still returns a bare `{ data: [] }`
-payload in the owning content spec and server implementation.
-
-The approved design treats the versions history endpoint as an in-scope list
-response for CMS-27. It will adopt the same pagination contract as
-`GET /api/v1/content`:
-
-- `limit` default `20`
-- `limit` max `100`
-- `offset` default `0`
-- success envelope `{ data, pagination: { total, limit, offset, hasMore } }`
-- newest-first version ordering remains unchanged
-
-## Spec Delta
-
-- Update `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
-  so `GET /api/v1/content/:documentId/versions` accepts `limit` and `offset`.
-- Change that endpoint's success contract from
-  `{ data: DocumentVersionSummary[] }` to
-  `{ data: DocumentVersionSummary[], pagination: { total, limit, offset, hasMore } }`.
-- Keep the shared list-envelope guidance in
-  `docs/specs/SPEC-005-auth-authorization-and-request-routing.md` unchanged.
-
-## Architecture
-
-The implementation stays scoped to content APIs but extracts the content-facing
-response types into `@mdcms/shared` so the server and CLI stop duplicating
-contract shapes.
-
-Add a new shared contract module for:
-
-- `ApiDataEnvelope<T>`
-- `ApiPaginatedEnvelope<T>`
-- `PaginationMetadata`
-- `ContentDocumentResponse`
-- `ContentVersionSummaryResponse`
-- `ContentVersionDocumentResponse`
-
-These remain type-only exports. Runtime route ownership, parsing, and
-authorization stay in `@mdcms/server`.
-
-## Server Changes
-
-- Update the content store interface so `listVersions(...)` returns
-  `{ rows, total, limit, offset }`, matching the existing `list(...)` contract.
-- Parse `limit` and `offset` for the versions listing route with the same
-  validation rules already used for `/api/v1/content`.
-- Add a small route-local helper for building the standard paginated envelope.
-- Keep single-document routes shaped as `{ data: ... }`, but type them against
-  the shared content response contracts.
-
-## Store Changes
-
-Both content store implementations must paginate version history after applying
-the existing newest-first sort:
-
-- `apps/server/src/lib/content-api/in-memory-store.ts`
-- `apps/server/src/lib/content-api/database-store.ts`
-
-Each store should return:
-
-- `rows`
-- `total`
-- `limit`
-- `offset`
-
-No persistence schema changes are required.
-
-## Consumer Changes
-
-`apps/cli/src/lib/pull.ts` and `apps/cli/src/lib/push.ts` currently duplicate
-content API payload shapes. They should import the shared content response
-types where those shapes already match current server behavior.
-
-This keeps CMS-27 scoped to content contracts without turning the task into a
-monorepo-wide response abstraction effort.
-
-## Error Handling
-
-No error semantics change in CMS-27:
-
-- invalid `limit` or `offset` stays `INVALID_QUERY_PARAM` (`400`)
-- missing document stays `NOT_FOUND` (`404`)
-- target-routing and authorization failures stay unchanged
-
-The task changes envelope consistency and pagination metadata only.
-
-## Testing
-
-Add or update contract coverage for:
-
-- versions list response envelope shape
-- versions pagination defaults
-- versions pagination with custom `limit` and `offset`
-- `hasMore` computation
-
-Keep existing content single-document response assertions aligned with the
-shared content response type definitions.
-
-## Documentation
-
-Document the public contract changes in:
-
-- `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
-- `apps/server/README.md`
-
-`docs/plans/` is local-only in this repository, so this design note is not
-intended to be committed.

-# CMS-27 Response Envelope Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Standardize content API response contracts for CMS-27 by adding shared content envelope types and paginating the versions history list endpoint.
-
-**Architecture:** Keep behavior ownership in `@mdcms/server`, but move the content API response shapes into `@mdcms/shared` so server and CLI consumers use one canonical contract. Extend `GET /api/v1/content/:documentId/versions` to use the same `limit`/`offset` and `{ data, pagination }` envelope rules as the main content list endpoint.
-
-**Tech Stack:** Bun, Nx, TypeScript, Zod, Elysia-style route handlers, Drizzle, Bun test
-
----
-
-### Task 1: Lock The Spec And Shared Contract Surface
-
-**Files:**
-
-- Create: `packages/shared/src/lib/contracts/content-api.ts`
-- Modify: `packages/shared/src/index.ts`
-- Modify: `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
-- Test: `apps/server/src/lib/content-api.test.ts`
-
-**Step 1: Write the failing test**
-
-Update the versions-list contract assertion in `apps/server/src/lib/content-api.test.ts` so it expects:
-
-```ts
-assert.equal(Array.isArray(versionsBody.data), true);
-assert.deepEqual(versionsBody.pagination, {
-  total: 1,
-  limit: 20,
-  offset: 0,
-  hasMore: false,
-});
-```
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun --cwd apps/server test ./src/lib/content-api.test.ts`
-Expected: FAIL because `GET /api/v1/content/:documentId/versions` currently returns no `pagination` field.
-
-**Step 3: Write minimal implementation**
-
-Create `packages/shared/src/lib/contracts/content-api.ts` with the canonical content response types:
-
-```ts
-export type ApiDataEnvelope<T> = { data: T };
-
-export type PaginationMetadata = {
-  total: number;
-  limit: number;
-  offset: number;
-  hasMore: boolean;
-};
-
-export type ApiPaginatedEnvelope<T> = {
-  data: T[];
-  pagination: PaginationMetadata;
-};
-```
-
-Also export content-specific response shapes from that module and re-export it from `packages/shared/src/index.ts`. Update `SPEC-003` so the versions listing endpoint explicitly accepts `limit`/`offset` and returns the paginated envelope.
-
-**Step 4: Run test to verify it still fails for the right reason**
-
-Run: `bun --cwd apps/server test ./src/lib/content-api.test.ts`
-Expected: FAIL remains isolated to route/store behavior, with shared contract types and spec text now in place.
-
-**Step 5: Commit**
-
-```bash
-git add packages/shared/src/lib/contracts/content-api.ts packages/shared/src/index.ts docs/specs/SPEC-003-content-storage-versioning-and-migrations.md apps/server/src/lib/content-api.test.ts
-git commit -m "feat: define shared content response contracts"
-```
-
-### Task 2: Paginate The Versions Route And In-Memory Store
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api/types.ts`
-- Modify: `apps/server/src/lib/content-api/routes.ts`
-- Modify: `apps/server/src/lib/content-api/in-memory-store.ts`
-- Modify: `apps/server/src/lib/content-api/responses.ts`
-- Test: `apps/server/src/lib/content-api.test.ts`
-
-**Step 1: Write the failing test**
-
-Extend `apps/server/src/lib/content-api.test.ts` with a versions-pagination scenario that creates multiple published versions and asserts:
-
-```ts
-const response = await handler(
-  new Request(
-    `http://localhost/api/v1/content/${created.data.documentId}/versions?limit=1&offset=1`,
-    { headers: scopeHeaders },
-  ),
-);
-
-assert.equal(response.status, 200);
-assert.equal(body.data.length, 1);
-assert.equal(body.pagination.total, 3);
-assert.equal(body.pagination.limit, 1);
-assert.equal(body.pagination.offset, 1);
-assert.equal(body.pagination.hasMore, true);
-assert.equal(body.data[0]?.version, 2);
-```
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun --cwd apps/server test ./src/lib/content-api.test.ts`
-Expected: FAIL because the versions route ignores `limit`/`offset` and returns an array without pagination metadata.
-
-**Step 3: Write minimal implementation**
-
-- Change `listVersions(...)` in `apps/server/src/lib/content-api/types.ts` to return:
-
-```ts
-Promise<{
-  rows: ContentVersionSummary[];
-  total: number;
-  limit: number;
-  offset: number;
-}>;
-```
-
-- In `apps/server/src/lib/content-api/routes.ts`, parse `limit` and `offset` from the query and return:
-
-```ts
-{
-  data: versions.rows.map((version) => toVersionSummaryResponse(version)),
-  pagination: {
-    total: versions.total,
-    limit: versions.limit,
-    offset: versions.offset,
-    hasMore: versions.offset + versions.limit < versions.total,
-  },
-}
-```
-
-- In `apps/server/src/lib/content-api/in-memory-store.ts`, sort versions newest-first, slice by `offset` and `limit`, and return metadata with `rows`.
-- In `apps/server/src/lib/content-api/responses.ts`, type the response mappers against the new shared contract types.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun --cwd apps/server test ./src/lib/content-api.test.ts`
-Expected: PASS for the updated envelope and pagination assertions in the in-memory-backed handler tests.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api/types.ts apps/server/src/lib/content-api/routes.ts apps/server/src/lib/content-api/in-memory-store.ts apps/server/src/lib/content-api/responses.ts apps/server/src/lib/content-api.test.ts
-git commit -m "feat: paginate content version history responses"
-```
-
-### Task 3: Match The Database Store And CLI Consumers To The Shared Contract
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api/database-store.ts`
-- Modify: `apps/cli/src/lib/pull.ts`
-- Modify: `apps/cli/src/lib/push.ts`
-- Test: `apps/server/src/lib/content-api.test.ts`
-- Test: `apps/cli/src/lib/pull.test.ts`
-- Test: `apps/cli/src/lib/push.test.ts`
-
-**Step 1: Write the failing test**
-
-Add a DB-backed versions listing assertion in `apps/server/src/lib/content-api.test.ts` that exercises the existing database store path and expects paginated metadata for the versions endpoint. Also switch CLI test fixtures and parsing call sites to the shared response types so type errors surface during test/typecheck.
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun --cwd apps/server test ./src/lib/content-api.test.ts`
-Expected: FAIL in the DB-backed versions listing path because `database-store.ts` still returns a plain array.
-
-Run: `bun --cwd apps/cli test ./src/lib/pull.test.ts ./src/lib/push.test.ts`
-Expected: either PASS with type drift still unaddressed or FAIL/typecheck errors once shared types are wired into the CLI call sites.
-
-**Step 3: Write minimal implementation**
-
-- Update `apps/server/src/lib/content-api/database-store.ts` to return `{ rows, total, limit, offset }` for `listVersions(...)` after newest-first sort and slicing.
-- Replace the inline content payload and envelope types in `apps/cli/src/lib/pull.ts` and `apps/cli/src/lib/push.ts` with imports from `@mdcms/shared` where they match the current server contract.
-
-**Step 4: Run tests to verify they pass**
-
-Run: `bun --cwd apps/server test ./src/lib/content-api.test.ts`
-Expected: PASS for both in-memory and database-backed versions list pagination behavior.
-
-Run: `bun --cwd apps/cli test ./src/lib/pull.test.ts ./src/lib/push.test.ts`
-Expected: PASS with CLI consumers still parsing the standardized content contract correctly.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api/database-store.ts apps/cli/src/lib/pull.ts apps/cli/src/lib/push.ts apps/server/src/lib/content-api.test.ts apps/cli/src/lib/pull.test.ts apps/cli/src/lib/push.test.ts
-git commit -m "refactor: reuse shared content API contracts"
-```
-
-### Task 4: Update Operator Docs And Run Full Verification
-
-**Files:**
-
-- Modify: `apps/server/README.md`
-- Test: `package.json` workspace scripts
-
-**Step 1: Write the doc update**
-
-Update `apps/server/README.md` so the content endpoint docs explicitly state:
-
-- `GET /api/v1/content/:documentId/versions` accepts `limit` and `offset`
-- versions history returns `{ data, pagination }`
-- default `limit` is `20` and max `100`
-
-**Step 2: Run focused verification**
-
-Run: `bun --cwd apps/server test ./src/lib/content-api.test.ts`
-Expected: PASS
-
-Run: `bun --cwd packages/shared test ./src`
-Expected: PASS
-
-Run: `bun --cwd apps/cli test ./src/lib/pull.test.ts ./src/lib/push.test.ts`
-Expected: PASS
-
-**Step 3: Run workspace verification**
-
-Run: `bun run format:check`
-Expected: PASS
-
-Run: `bun run check`
-Expected: PASS
-
-**Step 4: Confirm git hygiene**
-
-Run: `git status --short`
-Expected: modified task files only; local-only paths such as `AGENTS.md`, `ROADMAP_TASKS.md`, `.codex/`, `.claude/`, and `docs/plans/` must not be staged.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/README.md
-git commit -m "docs: document paginated content version responses"
-```

-# CMS-35 Contract Validation Suite Design
-
-**Task:** CMS-35 - Contract validation suite for extensibility
-
-**Date:** 2026-03-16
-
-## Scope Baseline
-
-Owning specs:
-
-- `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
-- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-- `docs/specs/README.md`
-
-Roadmap source:
-
-- `ROADMAP_TASKS.md` (`CMS-35`)
-
-No spec delta is required for this task. CMS-35 hardens existing extensibility
-contracts and registry behavior already defined in the owning specs.
-
-## Goal
-
-Add a CI-gated, fixture-driven contract validation suite for extensibility that:
-
-- validates module manifests, action catalog payloads, and Studio bootstrap
-  manifests with positive and negative fixtures
-- proves deterministic ordering and fail-fast collision behavior for server and
-  CLI registries
-- covers authorization-filtered action catalog behavior without pulling the full
-  Studio loader into scope
-- keeps failure output actionable for contributors and operators
-
-## In Scope
-
-- Contract validation for:
-  - `ModuleManifest`
-  - `ActionCatalogItem[]`
-  - `StudioBootstrapManifest`
-- Deterministic ordering tests for:
-  - server module loading and action collection
-  - CLI module loading and merged aliases/formatters/hooks
-- Collision tests for:
-  - duplicate module IDs
-  - duplicate action IDs
-  - conflicting server action routes via `(method, path)` collisions
-- Studio bootstrap publication verification for:
-  - manifest shape
-  - compatibility bounds
-  - asset-byte integrity against `integritySha256`
-  - placeholder signature/key invariants used by the current builder
-- Authorization coverage for:
-  - hidden actions omitted from `/api/v1/actions`
-  - hidden actions omitted from `/api/v1/actions/:id`
-  - forced access still rejected by protected server routes
-
-## Out Of Scope
-
-- Full `@mdcms/studio` runtime loader implementation
-- Loader-side network fetch and runtime execution
-- Runtime fallback / rollback / kill-switch behavior
-- Final production integrity/signature enforcement behavior for runtime loading
-- New extensibility surface contracts beyond those already owned by `SPEC-002`
-  and `SPEC-006`
-
-Those behaviors remain scheduled for later work, especially CMS-60 through
-CMS-62.
-
-## Chosen Approach
-
-Use a fixture-driven contract suite with one small pure verification helper for
-Studio bootstrap publications.
-
-Why this approach:
-
-- It matches CMS-35 acceptance criteria more directly than scattered ad hoc
-  tests.
-- It keeps CMS-35 in Phase 2 without dragging in loader/runtime execution.
-- It creates reusable validation seams that later Studio loader tasks can call
-  instead of re-deriving integrity and compatibility checks.
-
-## Package Responsibilities
-
-### `packages/shared`
-
-- Own manifest and action-catalog contract fixtures/tests.
-- Extend module planner collision detection to include duplicate server action
-  routes based on `(method, path)`.
-- Keep most fixtures local to tests unless a helper must be shared.
-
-### `packages/studio`
-
-- Add a pure bootstrap publication verifier.
-- Test valid and invalid bootstrap publications with deterministic fixtures.
-- Document that verification coverage exists before loader execution is added.
-
-### `apps/server`
-
-- Add server-facing tests for authorization-filtered action catalog behavior.
-- Add startup failure tests for duplicate action routes.
-
-### `apps/cli`
-
-- Prove deterministic merge order for CLI aliases, output formatters, and
-  preflight hooks across shuffled module inputs.
-
-### `packages/modules`
-
-- No production changes expected unless a very small test helper becomes
-  necessary.
-
-## Route Collision Interpretation
-
-CMS-35 acceptance requires collision coverage for conflicting routes, but the
-current extensibility contract does not expose an independent route manifest for
-arbitrary `mount()` behavior.
-
-To keep scope aligned with existing contracts, CMS-35 interprets route
-collisions as duplicate server action route declarations:
-
-- same HTTP method
-- same action `path`
-
-This covers the route metadata the extensibility system already owns without
-inventing a broader route-introspection contract.
-
-## Verification Strategy
-
-Planned validation flow:
-
-- `packages/shared` unit tests validate positive and negative contract fixtures.
-- `packages/shared` and app-level module-loader tests validate deterministic
-  ordering and collision reporting.
-- `packages/studio` unit tests validate bootstrap publication verification with
-  positive and negative fixtures.
-- Existing package `bun test ./src` targets remain the CI entrypoint; no new CI
-  orchestration layer is introduced in CMS-35.
-
-## Operator / Contributor Output
-
-Failure output should remain explicit about:
-
-- which manifest/action/bootstrap payload failed
-- which module or action caused the collision
-- which `(method, path)` route pair is duplicated
-- which integrity/signature/compatibility condition failed
-
-The suite should favor deterministic ordering of violations so failures are
-stable across repeated runs.

-# CMS-35 Contract Validation Suite Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Add a CI-gated extensibility contract suite for module manifests, action catalog payloads, Studio bootstrap publications, and deterministic server/CLI registry behavior without implementing the full Studio loader.
-
-**Architecture:** Keep contract ownership where it already lives. `@mdcms/shared` continues to own manifest and action-catalog validators plus runtime module planning. `@mdcms/studio` adds a pure bootstrap publication verifier for build outputs. `@mdcms/server` and `@mdcms/cli` extend tests around authorization-filtering, route collisions, and deterministic registry merging without introducing new runtime/plugin abstractions.
-
-**Tech Stack:** Bun, Nx, TypeScript, Bun test, Elysia, Zod
-
----
-
-### Task 1: Shared Contract Fixtures And Route Collision Detection
-
-**Files:**
-
-- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
-- Modify: `packages/shared/src/lib/contracts/action-catalog.test.ts`
-- Modify: `packages/shared/src/lib/runtime/module-loader-core.ts`
-- Modify: `packages/shared/src/lib/runtime/module-loader-core.test.ts`
-- Optional create: `packages/shared/src/lib/contracts/extensibility-test-fixtures.ts`
-
-**Step 1: Add positive and negative manifest fixtures**
-
-Add fixture values that cover:
-
-- valid manifest
-- empty `id`
-- invalid `apiVersion`
-- duplicate `dependsOn`
-- invalid semver bounds
-- inverted `minCoreVersion` / `maxCoreVersion`
-
-Keep fixtures local to tests unless re-use between multiple test files becomes noisy.
-
-**Step 2: Add positive and negative action catalog fixtures**
-
-Add fixture values that cover:
-
-- valid flattened metadata
-- invalid `permissions`
-- invalid `studio.form.mode`
-- invalid `cli.inputMode`
-- non-object `requestSchema`
-- non-object `responseSchema`
-- invalid list entries in array payloads
-
-**Step 3: Extend runtime module planning to detect route collisions**
-
-Update `buildRuntimeModulePlan(...)` in `packages/shared/src/lib/runtime/module-loader-core.ts` to treat duplicate server action route declarations as bootstrap violations when two server actions share the same:
-
-- `method`
-- `path`
-
-Add a new deterministic violation code only if needed; otherwise reuse the existing violation structure with a route-specific details payload.
-
-**Step 4: Add deterministic route-collision tests**
-
-In `packages/shared/src/lib/runtime/module-loader-core.test.ts`, add tests proving:
-
-- duplicate route pairs fail planning
-- collisions are reported deterministically across repeated runs
-- duplicate action IDs and duplicate route pairs are both preserved in violation output
-
-**Step 5: Run the shared package tests**
-
-Run:
-
-```bash
-bun test ./packages/shared/src
-```
-
-Expected:
-
-- all existing shared tests pass
-- new contract and route-collision tests pass
-
-**Step 6: Commit checkpoint**
-
-```bash
-git add packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/src/lib/contracts/action-catalog.test.ts packages/shared/src/lib/runtime/module-loader-core.ts packages/shared/src/lib/runtime/module-loader-core.test.ts
-git commit -m "test(shared): add extensibility contract fixtures"
-```
-
-Do not stage `docs/plans/` because repository rules keep those files untracked.
-
-### Task 2: Server And CLI Registry Regression Coverage
-
-**Files:**
-
-- Modify: `apps/server/src/lib/module-loader.test.ts`
-- Modify: `apps/server/src/lib/runtime-with-modules.test.ts`
-- Modify: `apps/server/src/lib/health.test.ts`
-- Modify: `apps/cli/src/lib/module-loader.test.ts`
-- Modify: `apps/cli/src/lib/runtime-with-modules.test.ts`
-
-**Step 1: Add server route-collision startup tests**
-
-Extend `apps/server/src/lib/module-loader.test.ts` so server bootstrap fails when two modules expose distinct action IDs but the same `(method, path)` pair.
-
-Cover:
-
-- deterministic violation ordering
-- actionable error details containing the route pair and both owners where possible
-
-**Step 2: Add authorization-filter enforcement coverage**
-
-In `apps/server/src/lib/runtime-with-modules.test.ts` or `apps/server/src/lib/health.test.ts`, add a protected route fixture proving:
-
-- an unauthorized action is hidden from `/api/v1/actions`
-- the hidden action also returns `404` from `/api/v1/actions/:id`
-- forcing the actual route still fails by server authorization, proving visibility metadata is advisory only
-
-Prefer a local test route with an explicit `authorize` gate instead of altering production module behavior.
-
-**Step 3: Expand CLI deterministic merge-order coverage**
-
-In CLI tests, prove merged:
-
-- `actionAliases`
-- `outputFormatters`
-- `preflightHooks`
-
-stay stable when input modules are shuffled but dependencies require a specific load order.
-
-**Step 4: Run targeted server and CLI tests**
-
-Run:
-
-```bash
-bun test ./apps/server/src/lib/module-loader.test.ts
-bun test ./apps/server/src/lib/runtime-with-modules.test.ts
-bun test ./apps/server/src/lib/health.test.ts
-bun test ./apps/cli/src/lib/module-loader.test.ts
-bun test ./apps/cli/src/lib/runtime-with-modules.test.ts
-```
-
-Expected:
-
-- new route-collision and authorization tests pass
-- deterministic ordering assertions stay stable
-
-**Step 5: Commit checkpoint**
-
-```bash
-git add apps/server/src/lib/module-loader.test.ts apps/server/src/lib/runtime-with-modules.test.ts apps/server/src/lib/health.test.ts apps/cli/src/lib/module-loader.test.ts apps/cli/src/lib/runtime-with-modules.test.ts
-git commit -m "test(server-cli): harden extensibility registry coverage"
-```
-
-### Task 3: Studio Bootstrap Publication Verification
-
-**Files:**
-
-- Modify: `packages/studio/src/lib/build-runtime.ts`
-- Modify: `packages/studio/src/lib/build-runtime.test.ts`
-- Modify: `packages/studio/src/index.ts`
-- Modify: `packages/studio/README.md`
-- Optional create: `packages/studio/src/lib/bootstrap-verification.ts`
-
-**Step 1: Add a pure bootstrap publication verifier**
-
-Implement a helper that accepts:
-
-- a `StudioBootstrapManifest`
-- the built runtime bytes
-- expected loader compatibility input
-
-It should validate:
-
-- manifest shape
-- compatibility fields
-- `integritySha256` matches asset bytes
-- placeholder signature/key format remains internally consistent for the current builder
-
-This helper must not fetch URLs or execute runtime code.
-
-**Step 2: Add positive and negative bootstrap fixtures**
-
-Cover:
-
-- valid publication
-- incompatible `minStudioPackageVersion`
-- incompatible `minHostBridgeVersion`
-- integrity mismatch from mutated runtime bytes
-- invalid placeholder signature
-- invalid placeholder key id
-- invalid manifest shape
-
-**Step 3: Export only if genuinely useful**
-
-If later tasks will clearly re-use the helper, export it through `packages/studio/src/index.ts`. Otherwise keep it internal to avoid widening public API unnecessarily.
-
-**Step 4: Document the verification boundary**
-
-Update `packages/studio/README.md` to state:
-
-- build outputs now have contract verification coverage
-- loader-side fetch/execution is still deferred to CMS-60+
-
-**Step 5: Run studio tests**
-
-Run:
-
-```bash
-bun test ./packages/studio/src
-```
-
-Expected:
-
-- existing Studio tests pass
-- bootstrap publication verification tests pass
-
-**Step 6: Commit checkpoint**
-
-```bash
-git add packages/studio/src/lib/build-runtime.ts packages/studio/src/lib/build-runtime.test.ts packages/studio/src/index.ts packages/studio/README.md
-git commit -m "test(studio): verify bootstrap publications"
-```
-
-### Task 4: Workspace Verification And Completion
-
-**Files:**
-
-- No new code files expected
-
-**Step 1: Run task-specific verification**
-
-Run:
-
-```bash
-bun test ./packages/shared/src
-bun test ./apps/server/src
-bun test ./apps/cli/src
-bun test ./packages/studio/src
-```
-
-Expected:
-
-- all touched package tests pass
-- no new flaky behavior appears
-
-**Step 2: Run required workspace validation**
-
-Run:
-
-```bash
-bun run format:check
-bun run check
-```
-
-Expected:
-
-- formatting check passes
-- build and typecheck pass across the workspace
-
-**Step 3: Inspect git status**
-
-Run:
-
-```bash
-git status --short
-```
-
-Expected:
-
-- only task-scoped source changes are staged or modified
-- local-only paths remain unstaged and uncommitted:
-  - `.claude/`
-  - `.codex/`
-  - `AGENTS.md`
-  - `CLAUDE.md`
-  - `ROADMAP_TASKS.md`
-  - `EXTENSIBILITY_APPROACH_COMPARISON.md`
-  - `mcp_servers.json`
-  - `docs/plans/`
-
-**Step 4: Final commit**
-
-```bash
-git add packages/shared/src apps/server/src apps/cli/src packages/studio/src packages/studio/README.md
-git commit -m "test: add cms-35 extensibility contract validation suite"

-# CMS-25 Published-Default Reads Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Enforce the CMS-25 visibility contract so content reads default to published snapshots, draft reads require `draft=true`, and draft list reads do not leak deleted documents unless explicitly requested.
-
-**Architecture:** Keep the existing route-level `draft=true` scope selection and published-vs-draft read split, but centralize list-visibility rules so the in-memory and database stores apply the same behavior. Drive the change with server contract tests first, then refactor the shared filtering logic with the narrowest production diff needed to satisfy the spec.
-
-**Tech Stack:** Bun, TypeScript, Node test runner, Elysia route handlers, Drizzle ORM, postgres.js
-
----
-
-### Task 1: Lock the visibility contract with failing tests
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api.test.ts`
-- Modify: `apps/server/src/lib/auth.test.ts`
-
-**Step 1: Write the failing test**
-
-Add focused tests that prove:
-
-- `GET /api/v1/content` returns only published snapshots by default.
-- `GET /api/v1/content?draft=true` returns mutable heads for published and unpublished docs.
-- `GET /api/v1/content?draft=true` excludes deleted docs unless `isDeleted=true` is explicitly requested.
-- API-key list reads require `content:read:draft` when `draft=true`.
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test apps/server/src/lib/content-api.test.ts apps/server/src/lib/auth.test.ts`
-Expected: FAIL because draft list reads currently include deleted rows and/or missing list-level auth coverage is not enforced by tests yet.
-
-**Step 3: Write minimal implementation**
-
-Do not change production code in this task.
-
-**Step 4: Run test to verify it still fails for the intended reason**
-
-Run: `bun test apps/server/src/lib/content-api.test.ts apps/server/src/lib/auth.test.ts`
-Expected: FAIL with the new visibility-contract assertion, not with a malformed test.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api.test.ts apps/server/src/lib/auth.test.ts
-git commit -m "test(server): add CMS-25 visibility contract coverage"
-```
-
-### Task 2: Refactor read visibility across both stores
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api/database-store.ts`
-- Modify: `apps/server/src/lib/content-api/in-memory-store.ts`
-- Modify: `apps/server/src/lib/content-api/types.ts`
-
-**Step 1: Write the failing test**
-
-Use the failing tests from Task 1 as the active red state. Do not add more production assumptions than those tests require.
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test apps/server/src/lib/content-api.test.ts apps/server/src/lib/auth.test.ts`
-Expected: FAIL on the CMS-25 visibility assertions.
-
-**Step 3: Write minimal implementation**
-
-Add a shared visibility decision for list reads that:
-
-- keeps published-default list behavior unchanged,
-- returns draft heads only when `draft=true`,
-- excludes deleted docs from draft list reads unless `isDeleted=true`,
-- still allows explicit `isDeleted=true/false` filtering for trash and non-trash views.
-
-Keep single-document behavior unchanged except where already covered by the existing spec/tests.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test apps/server/src/lib/content-api.test.ts apps/server/src/lib/auth.test.ts`
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api/database-store.ts apps/server/src/lib/content-api/in-memory-store.ts apps/server/src/lib/content-api/types.ts apps/server/src/lib/content-api.test.ts apps/server/src/lib/auth.test.ts
-git commit -m "feat(server): enforce CMS-25 draft visibility contract"
-```
-
-### Task 3: Verify task-scoped behavior and workspace health
-
-**Files:**
-
-- Modify: `apps/cli/src/lib/pull.test.ts` (only if the server contract change requires adjusted CLI assumptions)
-
-**Step 1: Write the failing test**
-
-Only if needed, add a CLI pull regression test showing that default pull still requests `draft=true` and published pull still requests published snapshots.
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test apps/cli/src/lib/pull.test.ts`
-Expected: FAIL only if a CLI regression or expectation mismatch is revealed.
-
-**Step 3: Write minimal implementation**
-
-Adjust CLI expectations only if the server contract refactor changes observable request semantics. Do not widen scope beyond CMS-25.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test apps/cli/src/lib/pull.test.ts`
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add apps/cli/src/lib/pull.test.ts
-git commit -m "test(cli): keep pull aligned with CMS-25 visibility rules"
-```
-
-### Task 4: Final verification
-
-**Files:**
-
-- No code changes expected
-
-**Step 1: Run targeted verification**
-
-Run: `bun test apps/server/src/lib/content-api.test.ts apps/server/src/lib/auth.test.ts apps/cli/src/lib/pull.test.ts`
-Expected: PASS
-
-**Step 2: Run workspace checks required by the repo workflow**
-
-Run: `bun run format:check`
-Expected: PASS
-
-Run: `bun run check`
-Expected: PASS
-
-**Step 3: Confirm local-only paths stay unstaged**
-
-Run: `git status --short`
-Expected: `docs/plans/`, `ROADMAP_TASKS.md`, `AGENTS.md`, and other local-only files remain untracked and unstaged.
-
-**Step 4: Commit**
-
-```bash

-# CMS-26 Resolve Reference Expansion Design
-
-## Context
-
-CMS-26 owns `resolve=` reference expansion for content reads. The current owning
-content spec defines `resolve` only as a list query parameter, while the SDK
-docs already show `resolve` on single-document reads. The approved design for
-this task closes that gap and defines deterministic read-time behavior for
-missing or invalid references.
-
-## Approved Decisions
-
-### Endpoint Scope
-
-`resolve` is supported on every endpoint that returns a full content payload:
-
-- `GET /api/v1/content`
-- `GET /api/v1/content/:documentId`
-- `GET /api/v1/content/:documentId/versions/:version`
-
-`resolve` is not added to `GET /api/v1/content/:documentId/versions` because
-that endpoint returns summaries, not full document payloads.
-
-### Resolution Mode
-
-- Resolution is shallow only.
-- The server expands exactly the fields named in `resolve`.
-- The server does not recurse into references inside resolved documents.
-
-### Scope And Visibility
-
-- Resolution is always constrained to the explicit `(project, environment)`
-  request target.
-- Published reads resolve against published-visible targets.
-- `draft=true` reads resolve against draft-visible targets.
-- Version snapshot reads resolve referenced targets using published-visible
-  reads because that endpoint does not expose `draft=true`.
-
-### Response Shape
-
-- Requested reference fields are replaced inline in the returned payload.
-- Successfully resolved fields become embedded content document objects.
-- Unresolved fields become `null`.
-- Each returned document may include an optional top-level `resolveErrors` map.
-- `resolveErrors` keys use full field paths, for example
-  `frontmatter.author` or `frontmatter.hero.author`.
-- `resolveErrors` is omitted when there are no resolution failures.
-
-Recommended unresolved shape:
-
-```json
-{
-  "resolveErrors": {
-    "frontmatter.author": {
-      "code": "REFERENCE_NOT_FOUND",
-      "message": "Referenced document could not be resolved in the target project/environment.",
-      "ref": {
-        "documentId": "uuid",
-        "type": "Author"
-      }
-    }
-  }
-}
-```
-
-### Validation And Error Semantics
-
-- `resolve` accepts repeated query params or equivalent string-array forms.
-- Each requested field path must map to a reference field in the resolved schema
-  for the returned document type.
-- Unknown fields, non-reference fields, or fields excluded from the target
-  environment schema fail deterministically with `INVALID_QUERY_PARAM` (`400`).
-- Stored target type metadata remains enforced during expansion.
-- Read-time failures for secondary referenced targets do not fail the primary
-  content read. They yield `null` plus `resolveErrors`.
-- `resolveErrors[*].code` must distinguish at least:
-  - `REFERENCE_NOT_FOUND`
-  - `REFERENCE_DELETED`
-  - `REFERENCE_TYPE_MISMATCH`
-  - `REFERENCE_FORBIDDEN`
-
-## Required Spec Delta
-
-### SPEC-003
-
-Update the content spec to:
-
-- add `resolve` to `GET /api/v1/content/:documentId`
-- add `resolve` to `GET /api/v1/content/:documentId/versions/:version`
-- define shallow-only semantics
-- define top-level `resolveErrors`
-- define deterministic validation and unresolved-reference behavior
-
-### SPEC-008
-
-Keep the SDK example aligned with the now-normative contract for single-document
-reads using `resolve`.
-
-## Verification Expectations
-
-CMS-26 implementation should verify:
-
-- list, single-document, and immutable-version reads all honor the same
-  `resolve` contract
-- version-summary reads remain unchanged
-- published reads do not leak draft-only referenced content
-- `draft=true` reads can resolve draft-visible referenced content
-- invalid `resolve` paths fail with `INVALID_QUERY_PARAM`
-- missing, deleted, type-mismatched, and forbidden referenced targets produce
-  `null` plus `resolveErrors`
-- all reference expansion remains bound to the explicit routed environment
-

-This design note is local workspace documentation under `docs/plans/` and
-should remain untracked per repository rules.

-# CMS-26 Resolve Reference Expansion Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Implement shallow `resolve=` reference expansion across all full
-content read endpoints, with environment-scoped validation and deterministic
-`resolveErrors` metadata for unresolved targets.
-
-**Architecture:** Keep base content reads in the existing content store and add
-a dedicated server-side reference-resolution layer for read responses. Validate
-requested field paths against schema registry snapshots for the routed
-environment, fetch referenced targets through existing content-store reads, and
-surface failures as `null` plus top-level `resolveErrors` keyed by full field
-paths.
-
-**Tech Stack:** Bun, Nx, TypeScript, Elysia, Drizzle, Postgres, Zod, Node test
-
----
-
-### Task 1: Update The Normative Contract
-
-**Files:**
-
-- Modify: `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
-- Modify: `docs/specs/SPEC-008-cli-and-sdk.md`
-- Modify: `packages/shared/src/lib/contracts/content-api.ts:17-56`
-
-**Step 1: Update the owning content spec**
-
-Add the approved `resolve` contract to the endpoint table and query-parameter
-sections in `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`.
-Document support for:
-
-- `GET /api/v1/content`
-- `GET /api/v1/content/:documentId`
-- `GET /api/v1/content/:documentId/versions/:version`
-
-Document these rules explicitly:
-
-- shallow-only resolution
-- top-level optional `resolveErrors`
-- full-path error keys
-- `null` for unresolved fields
-- `INVALID_QUERY_PARAM` for unknown/non-reference/excluded paths
-
-**Step 2: Align the SDK spec**
-
-Update `docs/specs/SPEC-008-cli-and-sdk.md` so its `cms.get(..., { resolve })`
-example and surrounding prose match the normative contract without adding any
-new SDK behavior beyond CMS-26.
-
-**Step 3: Extend the shared API response types**
-
-Update `packages/shared/src/lib/contracts/content-api.ts` so
-`ContentDocumentResponse` and `ContentVersionDocumentResponse` can carry
-optional resolution metadata:
-
-```ts
-export type ContentResolveError = {
-  code:
-    | "REFERENCE_NOT_FOUND"
-    | "REFERENCE_DELETED"
-    | "REFERENCE_TYPE_MISMATCH"
-    | "REFERENCE_FORBIDDEN";
-  message: string;
-  ref: {
-    documentId: string;
-    type: string;
-  };
-};
-
-export type ResolveErrorsMap = Record<string, ContentResolveError>;
-```
-
-Then add:
-
-```ts
-resolveErrors?: ResolveErrorsMap;
-```
-
-to the full-document response types only.
-
-**Step 4: Run typecheck**
-
-Run: `bun run typecheck`
-
-Expected: PASS for shared contract updates before server implementation begins.
-
-**Step 5: Commit**
-
-```bash
-git add docs/specs/SPEC-003-content-storage-versioning-and-migrations.md docs/specs/SPEC-008-cli-and-sdk.md packages/shared/src/lib/contracts/content-api.ts
-git commit -m "docs: define cms-26 resolve contract"
-```
-
-Do not stage or commit anything under `docs/plans/`.
-
-### Task 2: Add Failing CMS-26 Integration Coverage
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api.test.ts`
-
-**Step 1: Write the failing tests**
-
-Add targeted DB-backed tests in `apps/server/src/lib/content-api.test.ts` for:
-
-- list reads resolve a valid reference inline
-- single-document reads accept `resolve` and resolve inline
-- immutable version reads accept `resolve` and resolve inline
-- `GET /api/v1/content/:documentId/versions` ignores `resolve` support and
-  remains summary-only
-- invalid `resolve` field path returns `INVALID_QUERY_PARAM`
-- non-reference `resolve` field path returns `INVALID_QUERY_PARAM`
-- missing referenced target returns `null` plus
-  `resolveErrors["frontmatter.author"].code === "REFERENCE_NOT_FOUND"`
-- deleted referenced target returns `REFERENCE_DELETED`
-- type mismatch between stored ref metadata and fetched target returns
-  `REFERENCE_TYPE_MISMATCH`
-- forbidden referenced target returns `REFERENCE_FORBIDDEN`
-- published reads do not expand draft-only referenced targets
-- `draft=true` reads can expand draft-visible referenced targets
-
-Seed schema registry entries with reference metadata in the test fixture, for
-example:
-
-```ts
-const resolvedSchema = {
-  type: "BlogPost",
-  directory: "content/blog",
-  localized: true,
-  fields: {
-    author: {
-      kind: "string",
-      required: false,
-      nullable: true,
-      reference: { targetType: "Author" },
-    },
-  },
-};
-```
-
-Also add at least one nested path fixture, such as `frontmatter.hero.author`,
-to verify full-path keys in `resolveErrors`.
-
-**Step 2: Run the targeted tests to verify they fail**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/content-api.test.ts --test-name-pattern "resolve|reference"
-```
-
-Expected: FAIL because the routes currently accept `resolve` only on list reads
-and do not perform any reference expansion.
-
-**Step 3: Commit the failing tests**
-
-```bash
-git add apps/server/src/lib/content-api.test.ts
-git commit -m "test: codify cms-26 resolve behavior"
-```
-
-### Task 3: Implement Query Parsing And Schema Path Validation
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api/types.ts:54-190`
-- Modify: `apps/server/src/lib/content-api/parsing.ts:1-240`
-- Create: `apps/server/src/lib/content-api/reference-resolution.ts`
-- Modify: `apps/server/src/lib/content-api.ts`
-- Modify: `apps/server/src/lib/runtime-with-modules.ts`
-- Modify: `apps/server/src/lib/content-api.test.ts`
-
-**Step 1: Extend the route dependencies and query parsing**
-
-Update `apps/server/src/lib/content-api/types.ts` so route options can load the
-resolved schema for a type in the routed scope:
-
-```ts
-import type { SchemaRegistryTypeSnapshot } from "@mdcms/shared";
-
-export type ContentSchemaLookup = (
-  scope: ContentScope,
-  type: string,
-) => Promise<SchemaRegistryTypeSnapshot | undefined>;
-
-export type MountContentApiRoutesOptions = {
-  store: ContentStore;
-  authorize: ContentRequestAuthorizer;
-  requireCsrf: ContentRequestCsrfProtector;
-  getSchemaSnapshot: ContentSchemaLookup;
-};
-```
-
-In `apps/server/src/lib/content-api/parsing.ts`, add a parser that normalizes
-`resolve` from `string | string[] | undefined` into a deduplicated string array
-and rejects empty segments.
-
-**Step 2: Create the schema-aware resolver helpers**
-
-Create `apps/server/src/lib/content-api/reference-resolution.ts` with pure
-helpers to:
-
-- normalize field paths to full `frontmatter.*` paths
-- walk `SchemaRegistryTypeSnapshot.fields`
-- verify each requested path points at a reference field
-- extract `{ documentId, type }` from the stored reference value
-- build deterministic `RuntimeError` instances for invalid query paths
-
-Suggested shape:
-
-```ts
-export type ParsedResolveField = {
-  requestPath: string;
-  frontmatterPath: string;
-  segments: string[];
-  targetType: string;
-};
-
-export function parseResolveFields(
-  rawResolve: string | string[] | undefined,
-  schema: SchemaRegistryTypeSnapshot,
-): ParsedResolveField[] {
-  // normalize, validate, dedupe, throw INVALID_QUERY_PARAM on invalid input
-}
-```
-
-**Step 3: Wire schema lookup into the real server runtime**
-
-Update `apps/server/src/lib/runtime-with-modules.ts` so
-`mountContentApiRoutes()` receives `getSchemaSnapshot`. The callback should read
-`schema_registry_entries.resolved_schema` for the routed `(project, environment,
-type)` tuple using the existing database connection.
-
-Keep the `createHandler()` helper in `apps/server/src/lib/content-api.test.ts`
-working by passing a simple stub that returns `undefined` when tests do not
-exercise `resolve`.
-
-**Step 4: Run the targeted tests**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/content-api.test.ts --test-name-pattern "resolve|reference"
-```
-
-Expected: FAIL later in the flow because routes still do not perform reference
-expansion, but invalid-path cases should now be able to compile against the new
-helpers.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api/types.ts apps/server/src/lib/content-api/parsing.ts apps/server/src/lib/content-api/reference-resolution.ts apps/server/src/lib/content-api.ts apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/content-api.test.ts
-git commit -m "feat(server): add cms-26 resolve validation scaffolding"
-```
-
-### Task 4: Resolve References In Read Responses
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api/routes.ts:1-240`
-- Modify: `apps/server/src/lib/content-api/responses.ts:19-70`
-- Modify: `apps/server/src/lib/content-api/reference-resolution.ts`
-- Modify: `apps/server/src/lib/content-api.test.ts`
-
-**Step 1: Write the response-level resolution flow**
-
-In `apps/server/src/lib/content-api/reference-resolution.ts`, add a helper that
-resolves requested references for a returned document by:
-
-- validating the root document schema
-- reading the stored ref payload from `frontmatter`
-- fetching the target through `store.getById(scope, documentId, { draft })`
-- authorizing secondary reads against the resolved target path
-- returning an updated document payload plus `resolveErrors`
-
-Suggested shape:
-
-```ts
-export async function resolveDocumentReferences(input: {
-  document: ContentDocument | ContentVersionDocument;
-  scope: ContentScope;
-  resolveFields: ParsedResolveField[];
-  draft: boolean;
-  getById: ContentStore["getById"];
-  authorizeDocumentPath: (path: string) => Promise<void>;
-}): Promise<{
-  frontmatter: Record<string, unknown>;
-  resolveErrors?: ResolveErrorsMap;
-}> {
-  // replace successful fields inline
-  // set null + resolveErrors for missing/deleted/type mismatch/forbidden
-}
-```
-
-Use full field paths like `frontmatter.author` and `frontmatter.hero.author`
-when populating `resolveErrors`.
-
-**Step 2: Apply resolution to all full-document read endpoints**
-
-Update `apps/server/src/lib/content-api/routes.ts` so these endpoints parse and
-apply `resolve`:
-
-- `GET /api/v1/content`
-- `GET /api/v1/content/:documentId`
-- `GET /api/v1/content/:documentId/versions/:version`
-
-Do not change `GET /api/v1/content/:documentId/versions`.
-
-For list reads, resolve each returned document independently after the primary
-authorization checks succeed. For immutable version reads, resolve referenced
-targets via published-mode reads.
-
-**Step 3: Serialize `resolveErrors`**
-
-Update `apps/server/src/lib/content-api/responses.ts` so
-`toDocumentResponse()` and `toVersionDocumentResponse()` include
-`resolveErrors` when present and omit it when absent.
-
-**Step 4: Run the targeted tests to verify they pass**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/content-api.test.ts --test-name-pattern "resolve|reference"
-```
-
-Expected: PASS for the new CMS-26 cases.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api/routes.ts apps/server/src/lib/content-api/responses.ts apps/server/src/lib/content-api/reference-resolution.ts apps/server/src/lib/content-api.test.ts
-git commit -m "feat(server): implement cms-26 reference expansion"
-```
-
-### Task 5: Verify Adjacent Behavior And Finish
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api.test.ts`
-
-**Step 1: Add any missing regression coverage**
-
-Fill any remaining gaps found while implementing, especially:
-
-- published-default reads still behave like CMS-25
-- immutable version reads still return unchanged base snapshot fields
-- version-summary endpoint stays summary-only
-- non-`resolve` reads still omit `resolveErrors`
-
-**Step 2: Run the focused server test file**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/content-api.test.ts
-```
-
-Expected: PASS
-
-**Step 3: Run workspace validation required by repo policy**
-
-Run:
-
-```bash
-bun run format:check
-bun run check
-```
-
-Expected: PASS
-
-**Step 4: Inspect git status**
-
-Run:
-
-```bash
-git status --short
-```
-
-Expected:
-
-- code/spec files for CMS-26 are staged or committed as intended
-- local-only paths remain unstaged and untracked:
-  - `AGENTS.md`
-  - `ROADMAP_TASKS.md`
-  - `docs/plans/`
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api.test.ts
-git commit -m "test: finalize cms-26 regression coverage"
-```
-
-Do not stage or commit anything under `docs/plans/`.

-# CMS-28 CMS-29 Reference Identity And Schema Hash Gate Design
-
-## Context
-
-CMS-28 and CMS-29 both land on the same write-path seam in the content API.
-CMS-28 needs reference fields to persist stable environment-local document
-identities, while CMS-29 needs the server to reject draft-content writes when
-the client's local schema hash is missing, unsynced, or stale for the target
-environment.
-
-The approved design combines both tasks so the schema gate runs before any
-write-side reference validation. That lets CMS-28 rely on a synced target
-schema instead of carrying a permissive fallback that CMS-29 would immediately
-remove.
-
-## Approved Decisions
-
-### Endpoint Scope
-
-Schema-hash gating applies only to:
-
-- `POST /api/v1/content`
-- `PUT /api/v1/content/:documentId`
-
-It does not apply to `DELETE`, `restore`, `restore version`, `publish`, or
-`unpublish`.
-
-### Transport
-
-Clients send the local schema hash in a dedicated header:
-
-```http
-x-mdcms-schema-hash: <schemaHash>
-```
-
-The hash is request metadata, not content data, so it stays out of JSON bodies.
-
-### Deterministic Errors
-
-- Missing or blank header returns `SCHEMA_HASH_REQUIRED` (`400`).
-- Missing target schema sync record returns `SCHEMA_NOT_SYNCED` (`409`).
-- Non-matching client and server hashes return `SCHEMA_HASH_MISMATCH` (`409`).
-
-Recommended detail payloads:
-
-- `SCHEMA_HASH_REQUIRED`: `{ field: "x-mdcms-schema-hash" }`
-- `SCHEMA_NOT_SYNCED`: `{ project, environment }`
-- `SCHEMA_HASH_MISMATCH`:
-  `{ project, environment, clientSchemaHash, serverSchemaHash }`
-
-### Stored Reference Shape
-
-The current spec set is inconsistent about whether stored reference values are
-plain IDs or rich objects. The approved contract resolves that in favor of the
-simpler shape:
-
-- stored `frontmatter` reference values are plain env-local `document_id` UUID
-  strings
-- target type metadata remains schema-owned through `reference("TypeName")`
-- read-time `resolve=` expansion still turns stored IDs into inline documents
-
-### Write Validation Order
-
-For `POST /api/v1/content` and `PUT /api/v1/content/:documentId`, the server
-must:
-
-1. resolve target routing
-2. authorize the request
-3. validate `x-mdcms-schema-hash`
-4. load the target environment's schema sync record
-5. reject `SCHEMA_HASH_REQUIRED`, `SCHEMA_NOT_SYNCED`, or
-   `SCHEMA_HASH_MISMATCH` when applicable
-6. load the target environment's resolved schema for the effective content type
-7. validate reference-bearing fields in `frontmatter`
-8. persist the draft content
-
-### Reference Validation Rules
-
-- Validation walks nested object fields and arrays recursively.
-- Only fields declared as `reference(...)` in the resolved schema receive
-  special validation.
-- Each stored reference value must be a UUID string that resolves to a
-  non-deleted document in the same routed `(project, environment)` scope.
-- The referenced document's type must match the schema-declared target type.
-- Invalid shape, malformed UUID, missing target, deleted target, out-of-scope
-  target, and type mismatch all fail the write with `INVALID_INPUT` (`400`).
-- If the effective content type does not exist in the target environment's
-  resolved schema, the write fails with `INVALID_INPUT` (`400`).
-- This combined work does not introduce full schema validation for every
-  non-reference field. It only hardens reference identity plus the schema-hash
-  write gate.
-
-## Required Spec Delta
-
-### SPEC-004
-
-Update `docs/specs/SPEC-004-schema-system-and-sync.md` to define the schema
-gate for content draft-write endpoints:
-
-- required `x-mdcms-schema-hash` header
-- `SCHEMA_HASH_REQUIRED` (`400`)
-- `SCHEMA_NOT_SYNCED` (`409`)
-- `SCHEMA_HASH_MISMATCH` (`409`)
-- gate runs before content validation and persistence
-- stored references are plain env-local `document_id` strings
-
-### SPEC-003
-
-Update `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md` to:
-
-- state that reference fields persist plain env-local `document_id` UUID
-  strings
-- keep `resolve=` as read-time expansion only
-- add `x-mdcms-schema-hash` to the `POST /api/v1/content` and
-  `PUT /api/v1/content/:documentId` request contracts
-- add `SCHEMA_HASH_REQUIRED`, `SCHEMA_NOT_SYNCED`, and
-  `SCHEMA_HASH_MISMATCH` to those endpoint tables
-- keep `INVALID_INPUT` (`400`) for reference-validation failures
-
-## Verification Expectations
-
-Implementation should verify:
-
-- create and update reject missing schema hash headers
-- create and update reject unsynced target environments
-- create and update reject mismatched client/server schema hashes
-- matching schema hashes allow writes to continue normally
-- reference writes accept valid env-local UUID strings
-- reference writes reject malformed UUIDs
-- reference writes reject missing, deleted, wrong-type, and out-of-scope targets
-- nested object references and arrays of references are both validated
-- existing `resolve=` read behavior continues to work with stored string IDs
-
-## Notes
-
-This design note is local workspace documentation under `docs/plans/` and
-should remain untracked per repository rules.

-# CMS-28 CMS-29 Reference Identity And Schema Hash Gate Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Implement CMS-28 and CMS-29 together so content create/update writes
-require a matching target-environment schema hash and persist reference fields
-as validated env-local `document_id` UUID strings.
-
-**Architecture:** Keep the schema-hash gate at the route layer because it is an
-HTTP contract keyed off request headers and target-environment sync state. Keep
-reference validation in reusable content-store helpers so DB-backed routes,
-in-memory tests, and future write flows all enforce the same storage contract
-after the schema gate passes.
-
-**Tech Stack:** Bun, Nx, TypeScript, Elysia, Drizzle, Postgres, Zod, Node test
-
----
-
-### Task 1: Publish The Normative Contract
-
-**Files:**
-
-- Modify: `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
-- Modify: `docs/specs/SPEC-004-schema-system-and-sync.md`
-- Modify: `apps/server/README.md`
-
-**Step 1: Update the schema-system spec**
-
-Add the approved CMS-29 write-gate contract to
-`docs/specs/SPEC-004-schema-system-and-sync.md`. Document:
-
-- `x-mdcms-schema-hash` on `POST /api/v1/content`
-- `x-mdcms-schema-hash` on `PUT /api/v1/content/:documentId`
-- `SCHEMA_HASH_REQUIRED` (`400`)
-- `SCHEMA_NOT_SYNCED` (`409`)
-- `SCHEMA_HASH_MISMATCH` (`409`)
-- stored reference values are plain env-local `document_id` strings
-
-**Step 2: Update the content spec**
-
-Update `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md` so
-the reference section and endpoint table match the approved contract. Keep
-`resolve=` as read-time expansion only and keep `INVALID_INPUT` (`400`) as the
-reference-validation failure code.
-
-**Step 3: Update the point-of-use server docs**
-
-Add a short operator-facing note to `apps/server/README.md` covering:
-
-- required `x-mdcms-schema-hash` on content create/update
-- the three schema-gate errors
-- stored reference fields are env-local document ID strings
-
-**Step 4: Run format check for the doc edits**
-
-Run:
-
-```bash
-bun run format:check
-```
-
-Expected: PASS or only unrelated pre-existing failures outside these doc edits.
-
-**Step 5: Commit**
-
-```bash
-git add docs/specs/SPEC-003-content-storage-versioning-and-migrations.md docs/specs/SPEC-004-schema-system-and-sync.md apps/server/README.md
-git commit -m "docs: define cms-28 and cms-29 content write contract"
-```
-
-Do not stage or commit anything under `docs/plans/`.
-
-### Task 2: Add Failing Schema-Gate Coverage
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api.test.ts`
-
-**Step 1: Add failing route tests for missing and stale schema state**
-
-Add DB-backed route tests in `apps/server/src/lib/content-api.test.ts` for:
-
-- missing `x-mdcms-schema-hash` returns `SCHEMA_HASH_REQUIRED`
-- missing target schema sync record returns `SCHEMA_NOT_SYNCED`
-- mismatched header and server hash returns `SCHEMA_HASH_MISMATCH`
-- matching hash allows create/update to proceed
-
-Reuse the existing schema-seeding helpers where possible, and add one helper
-that can seed a known `schemaHash` for the target environment.
-
-**Step 2: Run the targeted tests to verify they fail**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/content-api.test.ts --test-name-pattern "schema hash|SCHEMA_HASH|not synced"
-```
-
-Expected: FAIL because content writes do not currently read or enforce the
-schema-hash header.
-
-**Step 3: Commit the failing tests**
-
-```bash
-git add apps/server/src/lib/content-api.test.ts
-git commit -m "test: codify cms-29 schema hash gate"
-```

-- Create: `apps/server/src/lib/content-api/schema-hash.ts`
-- Modify: `apps/server/src/lib/content-api/types.ts`
-- Modify: `apps/server/src/lib/content-api/parsing.ts`
-- Modify: `apps/server/src/lib/content-api/routes.ts`
-- Modify: `apps/server/src/lib/runtime-with-modules.ts`
-- Modify: `apps/server/src/lib/content-api.test.ts`
-
-**Step 1: Add a schema-sync lookup contract for content routes**
-
-Extend `apps/server/src/lib/content-api/types.ts` with a route dependency that
-can read the current schema sync state for a routed scope:
-
-```ts
-export type ContentSchemaSyncState = {
-  schemaHash: string;
-};
-
-export type ContentSchemaSyncLookup = (
-  scope: ContentScope,
-) => Promise<ContentSchemaSyncState | undefined>;
-```
-
-Add `getSchemaSyncState` to `MountContentApiRoutesOptions`.
-
-**Step 2: Add header parsing helpers**
-
-In `apps/server/src/lib/content-api/parsing.ts`, add a small parser that reads
-`x-mdcms-schema-hash`, trims it, and returns `undefined` for missing values.
-Keep error creation in the gate helper so the parser stays generic.
-
-**Step 3: Implement the gate helper**
-
-Create `apps/server/src/lib/content-api/schema-hash.ts` with pure helpers to:
-
-- read `x-mdcms-schema-hash`
-- throw `SCHEMA_HASH_REQUIRED` (`400`) on missing/blank values
-- throw `SCHEMA_NOT_SYNCED` (`409`) when no sync state exists
-- throw `SCHEMA_HASH_MISMATCH` (`409`) when the client hash differs from the
-  server hash
-
-Suggested entry point:
-
-```ts
-export async function assertSchemaHashMatches(input: {
-  request: Request;
-  scope: ContentScope;
-  getSchemaSyncState: ContentSchemaSyncLookup;
-}): Promise<void> {
-  // parse header, load sync state, throw RuntimeError when needed
-}
-```
-
-**Step 4: Wire the gate into create and update routes**
-
-Update `apps/server/src/lib/content-api/routes.ts` so `POST /api/v1/content`
-and `PUT /api/v1/content/:documentId` call `assertSchemaHashMatches(...)`
-before store writes. Do not add the gate to delete, restore, publish, or
-unpublish routes.
-
-**Step 5: Wire the real lookup into the runtime**
-
-Update `apps/server/src/lib/runtime-with-modules.ts` so
-`mountContentApiRoutes()` receives a `getSchemaSyncState` callback that reads
-the target `(project, environment)` row from `schemaSyncs`.
-
-For tests that mount routes directly, provide a lightweight stub callback.
-
-**Step 6: Run the targeted schema-gate tests**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/content-api.test.ts --test-name-pattern "schema hash|SCHEMA_HASH|not synced"
-```
-
-Expected: PASS for the new schema-gate cases.
-
-**Step 7: Commit**
-
-```bash
-git add apps/server/src/lib/content-api/schema-hash.ts apps/server/src/lib/content-api/types.ts apps/server/src/lib/content-api/parsing.ts apps/server/src/lib/content-api/routes.ts apps/server/src/lib/runtime-with-modules.ts apps/server/src/lib/content-api.test.ts
-git commit -m "feat(server): add cms-29 schema hash gate"
-```
-
-### Task 4: Add Failing Reference-Identity Coverage
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api.test.ts`
-
-**Step 1: Add failing create/update tests for reference writes**
-
-Add DB-backed tests in `apps/server/src/lib/content-api.test.ts` for:
-
-- valid reference UUID strings succeed on create and update when the schema hash
-  gate passes
-- malformed UUID strings return `INVALID_INPUT`
-- non-string reference values return `INVALID_INPUT`
-- missing referenced targets return `INVALID_INPUT`
-- deleted referenced targets return `INVALID_INPUT`
-- wrong-type referenced targets return `INVALID_INPUT`
-- nested object references validate recursively
-- arrays of references validate recursively
-
-Reuse the existing CMS-26 schema fixture and extend it with at least one array
-reference field so the write helper has both nested-object and array coverage.
-
-**Step 2: Add direct-store tests for DB and in-memory parity**
-
-Add focused direct-store tests proving both `createDatabaseContentStore(...)`
-and `createInMemoryContentStore(...)` enforce the same reference validation
-when schema snapshots are present for the target type.
-
-**Step 3: Run the targeted tests to verify they fail**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/content-api.test.ts --test-name-pattern "reference identity|reference write|cms-28"
-```
-
-Expected: FAIL because writes currently accept arbitrary JSON values in
-`frontmatter`.
-
-**Step 4: Commit the failing tests**
-
-```bash
-git add apps/server/src/lib/content-api.test.ts
-git commit -m "test: codify cms-28 reference identity"
-```
-
-### Task 5: Implement Reusable Reference Validation
-
-**Files:**
-
-- Create: `apps/server/src/lib/content-api/reference-validation.ts`
-- Modify: `apps/server/src/lib/content-api/database-store.ts`
-- Modify: `apps/server/src/lib/content-api/in-memory-store.ts`
-- Modify: `apps/server/src/lib/content-api/parsing.ts`
-- Modify: `apps/server/src/lib/content-api.test.ts`
-
-**Step 1: Create a reusable reference-validation helper**
-
-Create `apps/server/src/lib/content-api/reference-validation.ts` with pure
-schema walkers that:
-
-- traverse nested objects and arrays
-- detect reference-bearing fields from `SchemaRegistryTypeSnapshot`
-- validate that each stored value is a UUID string
-- return full frontmatter paths such as `frontmatter.author` or
-  `frontmatter.reviewers[0]`
-
-Suggested shape:
-
-```ts
-export type ReferenceValidationFailure = {
-  fieldPath: string;
-  reason:
-    | "invalid_shape"
-    | "invalid_uuid"
-    | "not_found"
-    | "deleted"
-    | "type_mismatch";
-  targetType: string;
-  documentId?: string;
-};
-```
-
-**Step 2: Integrate the helper into the database store**
-
-Update `apps/server/src/lib/content-api/database-store.ts` so create/update:
-
-- load the effective type schema for the routed environment
-- reject unknown types with `INVALID_INPUT`
-- validate reference fields before insert/update
-- resolve targets only within the same routed `(project, environment)`
-- reject deleted or wrong-type targets with `INVALID_INPUT`
-
-Keep non-reference field behavior unchanged.
-
-**Step 3: Integrate the helper into the in-memory store**
-
-Update `apps/server/src/lib/content-api/in-memory-store.ts` so the in-memory
-store enforces the same reference rules when schema snapshots are present.
-
-This keeps route tests and direct store tests aligned.
-
-**Step 4: Run the targeted reference tests**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/content-api.test.ts --test-name-pattern "reference identity|reference write|cms-28"
-```
-
-Expected: PASS for the new reference-write cases.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api/reference-validation.ts apps/server/src/lib/content-api/database-store.ts apps/server/src/lib/content-api/in-memory-store.ts apps/server/src/lib/content-api/parsing.ts apps/server/src/lib/content-api.test.ts
-git commit -m "feat(server): enforce cms-28 reference identity"

-
-**Step 1: Run the focused server suite**
-
-Run:
-
-```bash
-bun test apps/server/src/lib/content-api.test.ts
-```
-
-Expected: PASS for existing content API coverage plus the new CMS-28/CMS-29
-cases.
-
-**Step 2: Run workspace format check**
-
-Run:
-
-```bash
-bun run format:check

-```
-
-Expected: PASS.
-
-**Step 4: Confirm git hygiene**

-# CMS-32 Content Integration Design
-
-Date: 2026-03-18
-Task: CMS-32
-
-## Goal
-
-Turn the existing DB-backed content route coverage into a deterministic, CI-gated integration suite for lifecycle, routing, uniqueness, restore, schema-hash, and resolve behaviors.
-
-## Canonical Inputs
-
-- `ROADMAP_TASKS.md` CMS-32
-- `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
-- `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
-- `docs/specs/SPEC-009-i18n-and-environments.md`
-
-## Spec Delta
-
-No spec delta is required. CMS-32 only strengthens verification and CI gating for already-specified behavior.
-
-## Scope
-
-### In Scope
-
-- Extract DB-backed content route scenarios into a dedicated integration suite.
-- Keep in-memory content route tests for fast contract and smoke coverage.
-- Factor shared content test harness code into reusable support helpers.
-- Add a deterministic integration runner that boots Docker Compose, waits for services, runs the DB-backed suite, and tears the stack down.
-- Wire the new integration suite into the existing root `integration` command and CI job.
-- Document the new local operator workflow in the server README.
-
-### Out of Scope
-
-- Replacing the content store abstraction.
-- Removing `createInMemoryContentStore`.
-- Reworking the entire CI workflow structure.
-- Redesigning Docker Compose services beyond what is required to run the new suite.
-
-## Design Decisions
-
-### 1. Keep the In-Memory Store
-
-`createInMemoryContentStore` remains in the codebase.
-
-Its responsibility becomes:
-
-- fast route-level contract checks
-- parsing and validation coverage
-- envelope and pagination formatting checks
-- basic route/store smoke coverage
-
-It is no longer the evidence for production persistence semantics.
-
-### 2. Create a Dedicated DB-Backed Content Integration Suite
-
-Introduce a new integration-focused test file:
-
-- `apps/server/src/lib/content-api.integration.test.ts`
-
-This suite becomes the canonical regression gate for:
-
-- draft/publish/unpublish lifecycle
-- published-default vs `draft=true` reads
-- deleted visibility behavior
-- version history and immutable snapshots
-- restore flows and restore conflict handling
-- routing isolation across project/environment scope
-- DB uniqueness and conflict mapping
-- schema-hash enforcement on real write paths
-- DB-backed `resolve` behavior and its failure cases
-
-### 3. Extract Shared Test Support
-
-Move reusable DB test harness code into:
-
-- `apps/server/src/lib/content-api-test-support.ts`
-
-Expected shared helpers:
-
-- DB connectivity probe
-- authenticated test context creation
-- schema registry seeding
-- common scope headers
-- common request helpers
-- deterministic fixture/namespace helpers
-
-### 4. Make Fixtures Deterministic by Label
-
-Avoid `Date.now()` / `Math.random()` as the primary fixture naming mechanism inside the extracted integration suite.
-
-Each test should derive stable labels for:
-
-- project name
-- path segments
-- auth email
-- schema source ids
-
-This keeps the suite easier to debug and more repeatable against a fresh DB in CI.
-
-### 5. Add a Dedicated Integration Runner
-
-Introduce a root script:
-
-- `scripts/content-api-integration-check.sh`
-
-Responsibilities:
-
-1. Start Docker Compose with build.
-2. Wait for `postgres`, `db-migrate`, and `server` readiness.
-3. Run the dedicated server integration test command from the host workspace.
-4. Tear down the Compose stack and volumes on exit.
-
-Existing scripts remain:
-
-- `scripts/compose-health-check.sh`
-- `scripts/migration-startup-check.sh`
-
-### 6. Strengthen the Existing Integration Gate
-
-Update root `package.json` so `bun run integration` covers:
-
-1. compose health
-2. migration startup/schema validation
-3. content API DB integration suite
-
-The GitHub Actions integration job can continue calling `bun run integration`.
-
-## Test Ownership Split
-
-### Fast Route Suite
-
-`apps/server/src/lib/content-api.test.ts`
-
-Keeps:
-
-- in-memory route smoke coverage
-- parsing/query validation
-- response envelope assertions
-- routing-guard smoke behavior
-- any storage-independent checks that should stay fast
-
-### DB Integration Suite
-
-`apps/server/src/lib/content-api.integration.test.ts`
-
-Owns:
-
-- lifecycle and visibility
-- restore paths
-- routing isolation
-- uniqueness/conflict behavior
-- schema-hash transport and persistence behavior
-- DB-backed `resolve`
-- DB race/constraint precedence mapping
-
-## Verification
-
-Task completion should be backed by:
-
-- `bun run format:check`
-- `bun run check`
-- `bun run integration`
-
-## Notes
-
-- `docs/plans/` is local-only in this repository, so this design doc should remain untracked.
-- No public API contract changes are introduced; README documentation only needs to describe the new local integration workflow.

-# CMS-32 Content Integration Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Extract a dedicated DB-backed content integration suite, keep fast in-memory route tests, and wire the new suite into the root integration gate and CI path for CMS-32.
-
-**Architecture:** Split content API test ownership into a fast route-contract suite and a canonical DB-backed integration suite. Reuse a shared support module for test harness concerns, then run the DB suite through a dedicated Compose-backed shell script that becomes part of the root `integration` command.
-
-**Tech Stack:** Bun, Nx workspace scripts, Node test runner via `bun test`, Docker Compose, Postgres, Elysia route handler tests, Drizzle-backed content store
-
----
-
-### Task 1: Inventory and Carve Out Shared Test Support
-
-**Files:**
-
-- Create: `apps/server/src/lib/content-api-test-support.ts`
-- Modify: `apps/server/src/lib/content-api.test.ts`
-- Test: `apps/server/src/lib/content-api.test.ts`
-
-**Step 1: Write the failing test or import boundary**
-
-Move no DB-backed assertions yet. First add a support module export surface for existing helpers used by both suites:
-
-- `dbEnv`
-- `logger`
-- `scopeHeaders`
-- `createDatabaseTestContext(...)`
-- `seedSchemaRegistryScope(...)`
-- request helper utilities needed by extracted tests
-
-Expected first failure: `content-api.test.ts` cannot compile until imports are updated.
-
-**Step 2: Run test/typecheck to verify the extraction breaks before fix**
-
-Run: `bun test apps/server/src/lib/content-api.test.ts`
-Expected: FAIL or compile error from moved helpers/imports.
-
-**Step 3: Write minimal implementation**
-
-Create `apps/server/src/lib/content-api-test-support.ts` by moving shared DB harness code out of `content-api.test.ts`. Keep helper signatures unchanged where possible to minimize churn.
-
-**Step 4: Run tests to verify the extraction passes**
-
-Run: `bun test apps/server/src/lib/content-api.test.ts`
-Expected: PASS for the remaining suite or only DB-skipped tests remain skipped.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api-test-support.ts apps/server/src/lib/content-api.test.ts
-git commit -m "test(server): extract content api test support"
-```
-
-### Task 2: Create the Dedicated DB-Backed Integration Suite Skeleton
-
-**Files:**
-
-- Create: `apps/server/src/lib/content-api.integration.test.ts`
-- Modify: `apps/server/src/lib/content-api.test.ts`
-- Test: `apps/server/src/lib/content-api.integration.test.ts`
-
-**Step 1: Write the failing integration suite skeleton**
-
-Create a new integration file that imports the shared support helpers and defines at least one existing DB-backed test copied from `content-api.test.ts`.
-
-Expected first failure: the new file is not yet covered by a dedicated script and may expose missing imports/helpers.
-
-**Step 2: Run the new test file directly**
-
-Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
-Expected: FAIL from missing imports, missing helper exports, or copied code that still references old local helpers.
-
-**Step 3: Write minimal implementation**
-
-Fix imports and shared helper usage so the integration file runs. Keep `testWithDatabase` behavior for now if needed, but make the file structurally independent from `content-api.test.ts`.
-
-**Step 4: Re-run the new test file**
-
-Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
-Expected: PASS locally when Postgres is available; otherwise DB tests skip cleanly.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api.integration.test.ts apps/server/src/lib/content-api.test.ts
-git commit -m "test(server): add content api integration suite skeleton"
-```
-
-### Task 3: Move Canonical DB Lifecycle, Restore, and Routing Coverage
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api.integration.test.ts`
-- Modify: `apps/server/src/lib/content-api.test.ts`
-- Test: `apps/server/src/lib/content-api.integration.test.ts`
-
-**Step 1: Move the failing DB-backed scenarios**
-
-Move DB-backed tests for:
-
-- lifecycle and visibility
-- restore flows
-- routed project isolation
-
-Delete the moved DB-backed copies from `content-api.test.ts`.
-
-Expected first failure: copied tests still depend on old file-local state or helper functions.
-
-**Step 2: Run only the new integration file**
-
-Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
-Expected: FAIL on missing helper references or broken setup assumptions after the move.
-
-**Step 3: Write minimal implementation**
-
-Repair imports, helpers, and setup so moved tests run unchanged in behavior.
-
-**Step 4: Run the integration file again**
-
-Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
-Expected: PASS with DB available.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api.integration.test.ts apps/server/src/lib/content-api.test.ts
-git commit -m "test(server): move lifecycle restore and routing integration coverage"
-```
-
-### Task 4: Move DB Uniqueness, Conflict Mapping, Schema-Hash, and Resolve Coverage
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api.integration.test.ts`
-- Modify: `apps/server/src/lib/content-api.test.ts`
-- Test: `apps/server/src/lib/content-api.integration.test.ts`
-
-**Step 1: Move the remaining DB-backed regression groups**
-
-Move DB-backed tests for:
-
-- path conflict and translation variant conflict
-- soft-deleted or cross-scope source handling
-- race/constraint precedence checks
-- schema-hash required/mismatch/not-synced/match cases
-- DB-backed `resolve` scenarios
-
-Expected first failure: copied tests expose helper duplication or ordering assumptions.
-
-**Step 2: Run the integration file**
-
-Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
-Expected: FAIL until moved imports and local helpers are normalized.
-
-**Step 3: Write minimal implementation**
-
-Normalize helper usage and trim `content-api.test.ts` down to fast route tests plus any intentionally retained storage-independent checks.
-
-**Step 4: Re-run the integration file**
-
-Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
-Expected: PASS with DB available.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api.integration.test.ts apps/server/src/lib/content-api.test.ts
-git commit -m "test(server): move db content regressions into integration suite"
-```
-
-### Task 5: Add Deterministic Fixture Labels in the Integration Suite
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api-test-support.ts`
-- Modify: `apps/server/src/lib/content-api.integration.test.ts`
-- Test: `apps/server/src/lib/content-api.integration.test.ts`
-
-**Step 1: Write a failing deterministic helper expectation**
-
-Introduce helper usage so tests stop directly assembling names with `Date.now()` / `Math.random()` in moved CMS-32 scenarios.
-
-Expected first failure: compile errors until helper functions exist.
-
-**Step 2: Run the integration suite**
-
-Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
-Expected: FAIL on missing helper implementations.
-
-**Step 3: Write minimal implementation**
-
-Add small deterministic namespace helpers, for example:
-
-- `createTestNamespace(testId)`
-- `scopedPath(testId, suffix)`
-- `scopedEmail(testId)`
-
-Use a simple monotonic or label-driven strategy that is deterministic within the suite and unique per test case.
-
-**Step 4: Re-run the integration suite**
-
-Run: `bun test apps/server/src/lib/content-api.integration.test.ts`
-Expected: PASS with cleaner, label-driven fixtures.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/content-api-test-support.ts apps/server/src/lib/content-api.integration.test.ts
-git commit -m "test(server): make content integration fixtures deterministic"
-```
-
-### Task 6: Add a Dedicated Server Integration Command
-
-**Files:**
-
-- Modify: `apps/server/package.json`
-- Test: `apps/server/package.json`
-
-**Step 1: Write the failing command path**
-
-Add a new script entry such as:
-
-- `test:integration:content`
-
-that points at `src/lib/content-api.integration.test.ts`.
-
-Expected first failure: the script may not exist yet when invoked.
-
-**Step 2: Run the new script**
-
-Run: `bun run --cwd apps/server test:integration:content`
-Expected: FAIL before the script is added.
-
-**Step 3: Write minimal implementation**
-
-Add the script in `apps/server/package.json` using the same Bun test conventions already used in the package.
-
-**Step 4: Re-run the command**
-
-Run: `bun run --cwd apps/server test:integration:content`
-Expected: PASS with DB available, or clean skips when DB is unavailable outside Compose.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/package.json
-git commit -m "chore(server): add content integration test command"
-```
-
-### Task 7: Add the Compose-Backed Integration Check Script
-
-**Files:**
-
-- Create: `scripts/content-api-integration-check.sh`
-- Test: `scripts/content-api-integration-check.sh`
-
-**Step 1: Write the failing shell script skeleton**
-
-Create a script that:
-
-1. starts Docker Compose
-2. waits for `postgres`
-3. waits for `db-migrate`
-4. waits for `server`
-5. runs `bun run --cwd apps/server test:integration:content`
-6. tears down the stack with volumes on exit
-
-Expected first failure: shell syntax mistakes or missing readiness helpers.
-
-**Step 2: Run the script**
-
-Run: `bash scripts/content-api-integration-check.sh`
-Expected: FAIL the first time until readiness and cleanup logic is correct.
-
-**Step 3: Write minimal implementation**
-
-Model the script after the existing Compose health and migration scripts. Reuse the same waiting and cleanup patterns rather than inventing new shell behavior.
-
-**Step 4: Re-run the script**
-
-Run: `bash scripts/content-api-integration-check.sh`
-Expected: PASS and execute the DB-backed suite against a fresh Compose stack.
-
-**Step 5: Commit**
-
-```bash
-git add scripts/content-api-integration-check.sh
-git commit -m "test(ci): add content api integration check"
-```
-
-### Task 8: Wire the New Check into the Root Integration Gate
-
-**Files:**
-
-- Modify: `package.json`
-- Test: `package.json`
-
-**Step 1: Make the integration command fail until the new script is included**
-
-Update the root `integration` script to append `bash scripts/content-api-integration-check.sh`.
-
-Expected first failure: `bun run integration` now fails until the new script is correct.
-
-**Step 2: Run the root integration command**
-
-Run: `bun run integration`
-Expected: FAIL if any of the three checks still break under the new chain.
-
-**Step 3: Write minimal implementation**
-
-Adjust the script ordering or shell command if needed so the root integration flow is:
-
-1. compose health
-2. migration startup check
-3. content API integration check
-
-**Step 4: Re-run the root integration command**
-
-Run: `bun run integration`
-Expected: PASS.
-
-**Step 5: Commit**
-
-```bash
-git add package.json
-git commit -m "ci: gate integration on content api db suite"
-```
-
-### Task 9: Document the Local Operator Workflow
-
-**Files:**
-
-- Modify: `apps/server/README.md`
-- Test: `apps/server/README.md`
-
-**Step 1: Add the missing docs block**
-
-Document:
-
-- the fast suite command
-- the dedicated DB-backed content integration command
-- the root integration command that exercises the Compose-backed gate
-
-Expected first failure: no code failure; this is documentation completion tied to roadmap acceptance.
-
-**Step 2: Verify docs reflect real commands**
-
-Run:
-
-- `bun run --cwd apps/server test`
-- `bun run --cwd apps/server test:integration:content`
-- `bun run integration`
-
-Expected: all commands exist and docs text matches them exactly.
-
-**Step 3: Write minimal implementation**
-
-Add a concise README section under server testing or content API documentation.
-
-**Step 4: Re-check formatting**
-
-Run: `bun x prettier --check apps/server/README.md`
-Expected: PASS.
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/README.md
-git commit -m "docs(server): document content integration workflow"
-```
-
-### Task 10: Final Verification and Hygiene

-
-**Step 3: Run repo-level verification**
-
-Run:
-
-- `bun run format:check`
-- `bun run check`

-
-Expected: PASS.
-
-**Step 4: Verify change hygiene**
-
-Run: `git status --short`
-Expected:
-
-- only task-scoped tracked file changes are present
-- local-only paths like `AGENTS.md`, `ROADMAP_TASKS.md`, `.codex/`, `.claude/`, and `docs/plans/` remain unstaged/untracked

-# CMS-40 OIDC Provider Support Design
-
-Date: 2026-03-18
-Task: CMS-40
-
-## Goal
-
-Specify a concrete, minimal OIDC integration contract for MDCMS that uses the Better Auth SSO plugin with startup-configured providers, canonical claims mapping, and a deterministic fixture matrix.
-
-## Canonical Inputs
-
-- `ROADMAP_TASKS.md` CMS-40
-- `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
-- `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
-- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-- `docs/adrs/ADR-001-backend-framework-bun-elysia.md`
-
-## Spec Delta
-
-`SPEC-005` needs a normative OIDC section that:
-
-- makes the Better Auth SSO plugin the MDCMS OIDC mechanism
-- fixes CMS-40 to startup-configured provider profiles only
-- defines the supported provider set for this task
-- defines canonical claims mapping and deny-by-default error categories
-- adds the OIDC sign-in and callback routes to the auth endpoint family
-
-## Scope
-
-### In Scope
-
-- OIDC via Better Auth SSO plugin
-- Static startup provider configuration
-- Supported provider profile set:
-  - `okta`
-  - `azure-ad`
-  - `google-workspace`
-  - `auth0`
-- Canonical claims normalization for MDCMS users/sessions
-- Deterministic failure categories for config, sign-in initiation, callback, and missing required claims
-- Fixture-matrix expectations for the four provider profiles
-
-### Out of Scope
-
-- Runtime provider registration
-- Studio provider settings UI
-- SAML behavior beyond preserving the CMS-41 handoff
-- Arbitrary provider IDs outside the four CMS-40 profiles
-- Provider-specific operator workflows beyond startup config and restart
-
-## Design Decisions
-
-### 1. Standardize on Better Auth SSO Plugin
-
-MDCMS should explicitly standardize on the Better Auth SSO plugin for OIDC.
-
-This keeps MDCMS responsible for:
-
-- allowed provider profiles
-- startup config contract
-- canonical claim mapping
-- deterministic operator and test guarantees
-
-It leaves the protocol mechanics, callback handling, and discovery logic to Better Auth.
-
-### 2. Use Startup Configuration Only
-
-Provider definitions should be static server startup config for CMS-40.
-
-This avoids:
-
-- new admin APIs
-- secret management UI
-- provider CRUD persistence
-- runtime validation and rollback workflows
-
-Changes to provider configuration should require server restart.
-
-### 3. Keep the Provider Set Closed
-
-CMS-40 should make the supported provider set explicit and finite:
-
-- `okta`
-- `azure-ad`
-- `google-workspace`
-- `auth0`
-
-The fixture matrix then proves support for a known set rather than a vague "OIDC-compatible" promise.
-
-### 4. Fix the Canonical Claims Mapping
-
-The provider-specific OIDC profile shape should normalize to a single MDCMS user/session shape:
-
-- `id <- sub`
-- `email <- email`
-- `emailVerified <- email_verified` or `false` when missing
-- `name <- name`, then `given_name + family_name`, then `preferred_username`, then `email`
-- `image <- picture` or `null`
-
-Missing `sub` or usable `email` should fail sign-in deterministically.
-
-### 5. Restrict the MDCMS OIDC Surface
-
-CMS-40 should define MDCMS-supported usage of the Better Auth SSO plugin as:
-
-- initiate login with `providerId`
-- callback handled under `/api/v1/auth/sso/callback/:providerId`
-- relative or same-origin callback URLs only
-
-CMS-40 should not promise:
-
-- email/domain-based provider discovery
-- runtime provider registration
-- organization provisioning
-- shared redirect URI behavior
-
-## Verification
-
-Task completion should be backed by:
-
-- provider-fixture integration coverage for all four provider profiles
-- successful claims normalization assertions across the fixture matrix
-- negative coverage for missing claims and unconfigured provider IDs
-- `bun run format:check`
-- `bun run check`
-
-## Notes
-
-- `docs/plans/` is local-only in this repository, so this design doc should remain untracked.
-- This design intentionally prefers a closed provider matrix over a generic "any OIDC provider" promise so CMS-40 stays testable and bounded.

-# CMS-40 OIDC Provider Support Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Add startup-configured OIDC provider support to MDCMS using the Better Auth SSO plugin, canonical claims mapping, and a deterministic provider fixture matrix.
-
-**Architecture:** MDCMS keeps Better Auth SSO as the protocol and callback engine while owning a typed startup config contract, provider allowlist, claims normalization, and fixture-backed regression coverage. The implementation should validate provider config at startup, reject unsupported provider IDs by default, and keep the CMS-40 scope limited to static instance configuration.
-
-**Tech Stack:** Bun, Nx, TypeScript, Elysia, Better Auth, `@better-auth/sso`, Drizzle, Node test runner
-
----
-
-### Task 1: Lock the spec and operator contract
-
-**Files:**
-
-- Modify: `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
-- Modify: `apps/server/README.md`
-- Test: none
-
-**Step 1: Re-read the approved CMS-40 design and current auth spec**
-
-Run: `sed -n '1,260p' docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
-Expected: current auth section and endpoint table with no OIDC startup-config contract beyond generic SSO mention
-
-**Step 2: Update the auth spec with the CMS-40 OIDC delta**
-
-Add the normative sections for:
-
-- Better Auth SSO plugin as the MDCMS OIDC mechanism
-- startup-only provider configuration
-- supported provider IDs: `okta`, `azure-ad`, `google-workspace`, `auth0`
-- canonical claims mapping
-- OIDC sign-in and callback endpoint contracts
-- deterministic failure categories
-
-**Step 3: Update the server README with the operator workflow**
-
-Document:
-
-- the `MDCMS_AUTH_OIDC_PROVIDERS` startup env contract
-- restart requirement after config changes
-- supported provider IDs
-- callback URL restrictions
-
-**Step 4: Run formatting checks for the touched docs**
-
-Run: `bun run format:check`
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add docs/specs/SPEC-005-auth-authorization-and-request-routing.md apps/server/README.md
-git commit -m "docs(auth): specify CMS-40 oidc provider contract"
-```
-
-### Task 2: Add typed OIDC startup config parsing
-
-**Files:**
-
-- Modify: `apps/server/src/lib/env.ts`
-- Modify: `packages/shared/src/lib/runtime/env.ts` (only if shared parsing helpers are needed)
-- Modify: `.env.example`
-- Test: `packages/shared/src/lib/runtime/env.test.ts` or `apps/server/src/lib/*.test.ts`
-
-**Step 1: Write the failing env parsing test**
-
-Add focused tests covering:
-
-- valid `MDCMS_AUTH_OIDC_PROVIDERS` JSON
-- invalid JSON
-- unsupported `providerId`
-- duplicate provider IDs
-- missing required fields
-
-**Step 2: Run the targeted test to verify red**
-
-Run: `bun test packages/shared/src/lib/runtime/env.test.ts`
-Expected: FAIL on missing OIDC parsing behavior
-
-**Step 3: Implement minimal OIDC env parsing**
-
-Add a typed parser for:
-
-- `MDCMS_AUTH_OIDC_PROVIDERS`
-- provider shape: `providerId`, `issuer`, `domain`, `clientId`, `clientSecret`
-- optional `scopes`
-- optional `trustedOrigins`
-- optional discovery overrides for endpoint and token auth method fixes
-
-Reject malformed or unsupported provider entries with `INVALID_ENV`.
-
-**Step 4: Re-run the targeted test**
-
-Run: `bun test packages/shared/src/lib/runtime/env.test.ts`
-Expected: PASS
-
-**Step 5: Commit**

-```
-
-### Task 3: Wire Better Auth SSO into the server auth service
-
-**Files:**
-
-- Modify: `apps/server/package.json`
-- Modify: `apps/server/src/lib/auth.ts`
-- Test: `apps/server/src/lib/auth.test.ts`
-
-**Step 1: Write the failing auth-service tests**
-
-Add tests that prove:
-
-- configured provider profiles are registered at startup
-- unsupported provider IDs are rejected
-- callback URL validation is same-origin or relative-path only
-- missing required claims fail deterministically
-
-**Step 2: Run the targeted auth test**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-Expected: FAIL on missing SSO/OIDC behavior
-
-**Step 3: Add the minimal Better Auth SSO wiring**
-
-Implement:
-
-- `@better-auth/sso` dependency
-- plugin registration in `createAuthService(...)`
-- startup provider registration from parsed env config
-- canonical claims mapping
-- deny-by-default provider allowlist
-- callback URL validation
-
-Do not add runtime registration APIs or Studio settings UI.
-
-**Step 4: Re-run the targeted auth test**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-Expected: PASS for the new OIDC cases and existing auth coverage
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/package.json bun.lock apps/server/src/lib/auth.ts apps/server/src/lib/auth.test.ts

-### Task 4: Build the provider fixture matrix
-
-**Files:**
-
-- Create: `apps/server/src/lib/auth-oidc-fixtures.ts` or a similarly named test helper
-- Modify: `apps/server/src/lib/auth.test.ts`
-- Test: `apps/server/src/lib/auth.test.ts`
-
-**Step 1: Write the failing fixture-driven tests**
-
-Add one test per supported provider profile:
-
-- `okta`
-- `azure-ad`
-- `google-workspace`
-- `auth0`
-
-Each fixture should prove:
-
-- startup config is accepted
-- sign-in route targets the expected provider
-- canonical claims mapping yields the same MDCMS user fields
-
-Add negative fixtures for:
-
-- missing `email`
-- missing `sub`
-- unconfigured provider ID
-
-**Step 2: Run the fixture tests to verify red**
-
-Run: `bun test apps/server/src/lib/auth.test.ts --test-name-pattern="oidc|sso"`
-Expected: FAIL until fixture helpers and mappings exist
-
-**Step 3: Implement the minimal fixture helpers**
-
-Use deterministic local fixtures, not live SaaS tenants.
-
-The fixture helpers should:
-
-- create provider config inputs
-- create normalized user-info payloads per provider profile
-- assert the same MDCMS user/session output
-
-**Step 4: Re-run the fixture tests**
-
-Run: `bun test apps/server/src/lib/auth.test.ts --test-name-pattern="oidc|sso"`
-Expected: PASS
-
-**Step 5: Commit**

-Expected: PASS
-
-**Step 2: Run workspace checks**
-
-Run: `bun run check`
-Expected: PASS
-
-**Step 3: Run the targeted auth suite**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-Expected: PASS
-
-**Step 4: Inspect git status**
-
-Run: `git status --short`
-Expected: only task-scoped tracked changes; local-only files such as `docs/plans/` remain unstaged

-# CMS-41 SAML Provider Support Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Add startup-configured SAML 2.0 provider support to MDCMS using the existing Better Auth SSO plugin, provider-presence enablement, and deterministic ACS/metadata regression coverage.
-
-**Architecture:** Extend the current OIDC-only startup auth pipeline into a mixed static SSO registry. Keep OIDC and SAML operator config separate in env parsing, normalize both into Better Auth `defaultSSO` providers at startup, and add SAML-specific ACS plus SP metadata coverage without introducing runtime provider management or IdP-initiated flows.
-
-**Tech Stack:** Bun, Nx, TypeScript, Elysia, Better Auth, `@better-auth/sso`, Drizzle, `samlify`, Node test runner
-
----
-
-## Spec Delta
-
-- `docs/specs/SPEC-005-auth-authorization-and-request-routing.md` now defines startup-configured `MDCMS_AUTH_SAML_PROVIDERS`, provider-presence enablement, canonical SAML attribute mapping, and the `/api/v1/auth/sso/saml2/sp/acs/:providerId` and `/api/v1/auth/sso/saml2/sp/metadata` endpoints.
-- The affected behavior is in the server auth boundary only: startup env parsing, Better Auth SSO provider registration, shared `POST /api/v1/auth/sign-in/sso`, SAML ACS handling, and SP metadata exposure.
-- Acceptance criteria that depend on this delta:
-  - “disabled by default” now means no SAML providers are available when `MDCMS_AUTH_SAML_PROVIDERS` is absent or empty
-  - “enabled instances pass login flows” now means configured SAML providers complete SP-initiated sign-in and establish the normal MDCMS session
-  - deterministic failures must map to `INVALID_ENV`, `SSO_PROVIDER_NOT_CONFIGURED`, `AUTH_SAML_REQUIRED_ATTRIBUTE_MISSING`, and `AUTH_PROVIDER_ERROR`
-
-## Conflict Note
-
-- `ROADMAP_TASKS.md` still says `SAML beta-flag integration path`, but the owning spec has removed `beta` and the extra enablement flag.
-- Execute against the stricter spec-owned contract, not the stale roadmap wording.
-
-## Workspace Note
-
-- The current worktree already has unrelated unstaged changes in `packages/shared/`.
-- Implement this plan in a fresh worktree or with strict staged-file discipline so CMS-41 stays isolated.
-
-### Task 1: Add typed SAML startup config parsing
-
-**Files:**
-
-- Modify: `apps/server/src/lib/env.ts`
-- Modify: `apps/server/src/lib/env.test.ts`
-- Modify: `.env.example`
-
-**Step 1: Write the failing env parsing tests**
-
-Add focused tests for:
-
-- valid `MDCMS_AUTH_SAML_PROVIDERS` parsing
-- absent or blank `MDCMS_AUTH_SAML_PROVIDERS` returning `[]`
-- malformed JSON
-- non-array payload
-- missing required SAML fields (`providerId`, `issuer`, `domain`, `entryPoint`, `cert`)
-- duplicate SAML domains
-- duplicate `providerId` across OIDC and SAML provider sets
-
-**Step 2: Run the targeted env test to verify red**
-
-Run: `bun test apps/server/src/lib/env.test.ts`
-Expected: FAIL on missing SAML parsing/types or missing cross-protocol uniqueness checks
-
-**Step 3: Implement minimal SAML env parsing**
-
-Add a typed parser for:
-
-- `MDCMS_AUTH_SAML_PROVIDERS`
-- required fields: `providerId`, `issuer`, `domain`, `entryPoint`, `cert`
-- optional fields: `audience`, `spEntityId`, `identifierFormat`, `authnRequestsSigned`, `wantAssertionsSigned`, `attributeMapping`
-
-Implementation details:
-
-- extend `ServerEnv` with `MDCMS_AUTH_SAML_PROVIDERS`
-- preserve the current OIDC parser unchanged except for shared cross-protocol `providerId` uniqueness
-- keep missing or blank `MDCMS_AUTH_SAML_PROVIDERS` equivalent to “no configured SAML providers”
-- keep errors as deterministic `INVALID_ENV` envelopes keyed to the offending env var
-
-**Step 4: Update the operator env example**
-
-Add a commented `MDCMS_AUTH_SAML_PROVIDERS` example to `.env.example` alongside the existing OIDC example and note that providers are enabled by presence, not by a separate flag.
-
-**Step 5: Re-run the targeted env test**
-
-Run: `bun test apps/server/src/lib/env.test.ts`
-Expected: PASS
-
-**Step 6: Commit**
-
-```bash
-git add apps/server/src/lib/env.ts apps/server/src/lib/env.test.ts .env.example
-git commit -m "feat(server): parse startup saml provider config"
-```
-
-### Task 2: Extend the auth service to register static SAML providers
-
-**Files:**
-
-- Modify: `apps/server/src/lib/auth.ts`
-- Modify: `apps/server/src/lib/auth.test.ts`
-
-**Step 1: Write the failing auth-service tests**
-
-Add unit-level tests proving:
-
-- the shared SSO sign-in payload accepts a configured SAML `providerId`
-- `SSO_PROVIDER_NOT_CONFIGURED` is protocol-neutral, not OIDC-only
-- static SAML provider config is converted into Better Auth SSO provider input
-- the Better Auth plugin options enable the required SAML protections:
-  - `enableInResponseToValidation: true`
-  - `allowIdpInitiated: false`
-  - `requireTimestamps: true`
-
-**Step 2: Run the targeted auth test to verify red**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-Expected: FAIL on missing SAML provider building or OIDC-specific error/messages
-
-**Step 3: Implement the minimal mixed-protocol provider registry**
-
-Implement in `apps/server/src/lib/auth.ts`:
-
-- a `SamlProviderConfig` runtime mapping compatible with `@better-auth/sso`
-- a builder that converts parsed SAML env config into Better Auth `defaultSSO` entries
-- a combined configured-provider allowlist across OIDC and SAML
-- protocol-neutral `SSO_PROVIDER_NOT_CONFIGURED` and `AUTH_PROVIDER_ERROR` messages where the code path is shared
-- shared callback URL validation for both protocols
-- Better Auth `sso(...)` registration with:
-  - all OIDC providers
-  - all SAML providers
-  - required SAML validation options from the spec
-
-Do not add:
-
-- runtime provider registration
-- Studio-managed SSO settings
-- IdP-initiated login
-- SAML Single Logout
-
-**Step 4: Re-run the targeted auth test**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-Expected: PASS for the new provider-registry assertions and existing OIDC regressions
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/auth.ts apps/server/src/lib/auth.test.ts
-git commit -m "feat(server): register static saml providers"
-```
-
-### Task 3: Add deterministic SAML fixture helpers
-
-**Files:**
-
-- Create: `apps/server/src/lib/auth-saml-fixtures.ts`
-- Modify: `apps/server/src/lib/auth.test.ts`
-
-**Step 1: Write the failing fixture-driven SAML tests**
-
-Add integration-style coverage in `apps/server/src/lib/auth.test.ts` for:
-
-- configured SAML sign-in starts from `POST /api/v1/auth/sign-in/sso`
-- SP metadata endpoint returns `200` for a configured SAML provider
-- ACS success establishes a session and redirects to `/studio`
-- missing mapped `email` or `id` becomes `AUTH_SAML_REQUIRED_ATTRIBUTE_MISSING`
-- unconfigured provider returns `SSO_PROVIDER_NOT_CONFIGURED`
-- unsolicited IdP response is rejected
-- replayed assertion is rejected
-
-**Step 2: Run the targeted auth test to verify red**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-Expected: FAIL on missing SAML test helpers and missing ACS/metadata support
-
-**Step 3: Implement the SAML fixture helper**
-
-Create `apps/server/src/lib/auth-saml-fixtures.ts` with deterministic helpers that:
-
-- define a startup-valid SAML provider config
-- generate reusable test certificates/private keys
-- decode the SP-initiated `SAMLRequest` created by the sign-in step so tests can reuse the exact request ID
-- generate signed SAML responses for:
-  - success
-  - missing email
-  - missing id
-  - replay reuse
-  - missing `InResponseTo`
-
-Prefer local deterministic XML generation over live IdP/network tests.
-
-**Step 4: Re-run the targeted auth test**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-Expected: FAIL only on missing runtime ACS/metadata behavior
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/auth-saml-fixtures.ts apps/server/src/lib/auth.test.ts
-git commit -m "test(server): add saml auth fixtures"
-```
-
-### Task 4: Add ACS and SP metadata route handling
-
-**Files:**
-
-- Modify: `apps/server/src/lib/auth.ts`
-- Modify: `apps/server/src/lib/auth.test.ts`
-
-**Step 1: Keep the SAML endpoint tests red and focused**
-
-Make sure the integration tests explicitly verify:
-
-- `GET /api/v1/auth/sso/saml2/sp/metadata?providerId=<id>&format=xml` returns metadata that references the configured ACS URL
-- `POST /api/v1/auth/sso/saml2/sp/acs/:providerId` accepts a valid signed response and issues the normal MDCMS session
-- missing mapped attributes surface `AUTH_SAML_REQUIRED_ATTRIBUTE_MISSING`
-- unsolicited or replayed responses surface deterministic failure envelopes
-
-**Step 2: Run the targeted auth test to confirm red**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-Expected: FAIL on missing route mounts or incorrect SAML error translation
-
-**Step 3: Implement the minimal route support**
-
-In `apps/server/src/lib/auth.ts`:
-
-- add route mounts for:
-  - `POST /api/v1/auth/sso/saml2/sp/acs/:providerId`
-  - `GET /api/v1/auth/sso/saml2/sp/metadata`
-- route both through `auth.handler(...)` with the same runtime error wrapping used for existing auth endpoints
-- add SAML-specific error mapping so:
-  - missing mapped identity fields become `AUTH_SAML_REQUIRED_ATTRIBUTE_MISSING`
-  - unsupported provider IDs become `SSO_PROVIDER_NOT_CONFIGURED`
-  - assertion validation/replay/issuer/signature failures become `AUTH_PROVIDER_ERROR`
-- add post-callback user normalization for the SAML ACS path similar to the existing OIDC callback normalization, but using the SAML attribute mapping defined in the provider config
-
-**Step 4: Re-run the targeted auth test**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-Expected: PASS for the new SAML route coverage and all pre-existing OIDC regressions
-
-**Step 5: Commit**
-
-```bash
-git add apps/server/src/lib/auth.ts apps/server/src/lib/auth.test.ts
-git commit -m "feat(server): add saml acs and metadata routes"
-```
-
-### Task 5: Update operator-facing auth documentation
-
-**Files:**
-
-- Modify: `apps/server/README.md`
-- Modify: `.env.example` (only if more examples are still needed after Task 1)
-
-**Step 1: Update the server README**
-
-Document:
-
-- `MDCMS_AUTH_SAML_PROVIDERS`
-- provider-presence enablement semantics
-- required and optional SAML fields
-- ACS and SP metadata routes
-- SP-initiated-only scope
-- callback URL restrictions shared with OIDC
-
-**Step 2: Run formatting checks for touched docs**
-
-Run: `bun run format:check`
-Expected: PASS
-
-**Step 3: Commit**
-
-```bash
-git add apps/server/README.md .env.example
-git commit -m "docs(server): document saml provider support"
-```
-
-### Task 6: Verify the full CMS-41 slice
-
-**Files:**
-
-- Modify: none unless verification fixes are required
-
-**Step 1: Run the env parser suite**
-
-Run: `bun test apps/server/src/lib/env.test.ts`
-Expected: PASS
-
-**Step 2: Run the auth suite**
-
-Run: `bun test apps/server/src/lib/auth.test.ts`
-Expected: PASS
-
-**Step 3: Run formatting**
-
-Run: `bun run format:check`
-Expected: PASS
-
-**Step 4: Run the workspace baseline**
-
-Run: `bun run check`
-Expected: PASS
-
-**Step 5: Inspect git status**
-
-Run: `git status --short`
-Expected:
-
-- only CMS-41 task-scoped files are staged or modified
-- unrelated local-only paths such as `.claude/`, `.codex/`, `ROADMAP_TASKS.md`, and `docs/plans/` remain unstaged
-
-**Step 6: Final verification commit if fixes were needed**
-
-```bash
-git add <cms-41-files>
-git commit -m "test(server): finalize cms-41 verification"
-```

-# Week 3 Scope and Recommended Sequencing
-
-Date: 2026-03-20
-
-Sources:
-
-- Week 3 screenshot provided in chat
-- `ROADMAP_TASKS.md`
-- `docs/specs/README.md`
-
-## Jira Status Note
-
-Live Jira status lookup was not reliable in this session. This report covers:
-
-- the visible Week 3 scope from the screenshot
-- roadmap task mapping
-- dependency-based sequencing
-
-It does **not** claim current `Done` / `To Do` counts for Week 3.
-
-## Week 3 Screenshot Transcription
-
-Visible text in the Week 3 column:
-
-- `Week 3`
-- `Platform (83d)`
-- `N - Studio Content (24d)`  
-  `CMS-56-67,75,76`
-- `O - MDX Components (21d)`  
-  `CMS-68-74`
-- `P - Studio Runtime (7.5d)`  
-  `CMS-60,61,62`
-- `T - SDK (3.5d)`  
-  `CMS-85`
-- `Q - CLI Commands (27d)`  
-  `CMS-77-87`
-
-## Important Screenshot Caveats
-
-The Week 3 screenshot is not a clean list of unique tasks.
-
-1. `P - Studio Runtime` duplicates `CMS-60,61,62`, which already sit inside the broader `CMS-56-67` range under `N - Studio Content`.
-2. `T - SDK` duplicates `CMS-85`, which already sits inside the broader `CMS-77-87` range under `Q - CLI Commands`.
-
-Because of that, the screenshot appears to mix:
-
-- broad streams (`N`, `O`, `Q`)
-- narrower callout substreams (`P`, `T`)
-
-For planning purposes, the unique Week 3 tasks visible in the screenshot are:
-
-- `CMS-56` through `CMS-87`
-
-## Roadmap Override To The Screenshot
-
-Two tasks that appear inside the screenshot ranges are explicitly re-homed by the roadmap and no longer gate MVP:
-
-- `CMS-58`
-- `CMS-86`
-
-That matters because the screenshot still visually includes them:
-
-- `CMS-58` falls inside `CMS-56-67`
-- `CMS-86` falls inside `CMS-77-87`
-
-For strict MVP sequencing, treat those two as **deferred** unless you intentionally pull them back in.
-
-## Week 3 Unique Task Set
-
-### Studio / Runtime / Content
-
-- `CMS-56` Implement publish flow + version history panel + version diff view

-
-## Key Dependency Chains Inside Week 3
-
-### Studio Runtime
-
-- `CMS-60 -> CMS-61 -> CMS-62`
-
-### Locale / Translation UI
-
-- `CMS-63 -> CMS-64`
-
-### MDX Components
-
-- `CMS-68 -> CMS-69 -> CMS-70 -> CMS-71 -> CMS-72 -> CMS-73 -> CMS-74`
-
-`CMS-74` also depends on `CMS-52`, which is outside Week 3.
-
-### CLI Core
-
-- `CMS-77 -> CMS-78`
-- `CMS-77 -> CMS-79`
-- `CMS-77 -> CMS-80 -> CMS-81 -> CMS-82 -> CMS-83`
-- `CMS-81 -> CMS-84`
-- `CMS-77 -> CMS-87`
-
-### SDK
-
-- `CMS-85` is independent of the `CMS-77` CLI chain. It depends on `CMS-17` and `CMS-21`, both outside Week 3.
-
-### Deferred
-
-- `CMS-58` depends on `CMS-52` and `CMS-54`
-- `CMS-86` depends on `CMS-82` and `CMS-53`
-
-Both are roadmap-deferred from MVP.
-
-## External Prerequisite Note
-
-Many Week 3 tasks depend on non-Week-3 tasks such as:
-
-- `CMS-48`, `CMS-49`, `CMS-50`
-- `CMS-52`
-- `CMS-17`, `CMS-18`, `CMS-19`, `CMS-20`, `CMS-24`, `CMS-42`, `CMS-44`
-
-This report does not claim those external prerequisites are complete. It only lays out the Week 3 structure and the internal dependency sequence.
-
-## Recommended Sequencing
-
-Week 3 is too broad for one useful single-file linear order. The practical approach is to run it in dependency-led tracks.
-
-### Recommended Priority Wave 1: Highest Fan-Out Foundations
-
-Start with the items that unlock the largest amount of Week 3 work:
-
-1. `CMS-60` Studio runtime loader + composition surfaces
-2. `CMS-68` component registration sync contract
-3. `CMS-77` CLI framework with profile/auth plumbing
-4. `CMS-85` SDK client
-
-Why:
-
-- `CMS-60` unlocks the entire runtime chain (`61`, `62`)
-- `CMS-68` starts the full MDX component chain (`69` through `74`)
-- `CMS-77` is the CLI root for `78`, `79`, `80`, and `87`
-- `CMS-85` is independent and valuable enough to run immediately in parallel
-
-### Recommended Priority Wave 2: Close The Long Chains
-
-Once Wave 1 foundations are active, continue each chain in order:
-
-#### Runtime chain
-
-1. `CMS-61`
-2. `CMS-62`
-
-#### MDX component chain
-
-1. `CMS-69`
-2. `CMS-70`
-3. `CMS-71`
-4. `CMS-72`
-5. `CMS-73`
-6. `CMS-74`
-
-#### CLI chain
-
-1. `CMS-79`
-2. `CMS-80`
-3. `CMS-87`
-4. `CMS-78`
-5. `CMS-81`
-6. `CMS-82`
-7. `CMS-83`
-8. `CMS-84`
-
-Why this CLI ordering:
-
-- `CMS-79`, `CMS-80`, and `CMS-87` sit directly off `CMS-77`
-- `CMS-81` cannot start until `CMS-80`
-- `CMS-82` cannot start until `CMS-81`
-- `CMS-83` and `CMS-84` are tail tasks off the push/manifest path
-- `CMS-78` depends only on `CMS-77`, so it can move earlier or later based on resourcing
-
-### Recommended Priority Wave 3: Studio Content and Admin Flows
-
-Run the Studio content/admin tasks as a parallel product track once their external prerequisites are ready:
-
-- `CMS-65` Studio environment management basics
-- `CMS-66` Studio project switcher
-- `CMS-75` Studio user management UI
-- `CMS-76` Studio API key management UI
-- `CMS-63` locale switcher
-- `CMS-64` translation status indicators
-- `CMS-67` environment-specific field badges
-- `CMS-57` schema mismatch banner / read-only mode
-- `CMS-59` read-only schema browsing
-- `CMS-56` publish flow + version history + diff
-
-Suggested order inside this track:
-
-1. `CMS-65`
-2. `CMS-66`
-3. `CMS-75`
-4. `CMS-76`
-5. `CMS-63`
-6. `CMS-64`
-7. `CMS-67`
-8. `CMS-57`
-9. `CMS-59`
-10. `CMS-56`
-
-Why:
-
-- `65`, `66`, `75`, and `76` provide foundational project/environment/admin surfaces
-- `63 -> 64` is the only strict internal chain here
-- `56`, `57`, and `59` are more specialized experience layers and can safely come after the core Studio navigation/admin surfaces
-
-### Deferred From MVP
-
-Do not put these on the MVP-critical Week 3 path unless you intentionally want deferred work:
-
-- `CMS-58`
-- `CMS-86`
-
-## Short Recommendation
-
-If the goal is to reduce rework and unblock the most Week 3 work quickly:
-
-1. Start `CMS-60`, `CMS-68`, `CMS-77`, and `CMS-85`
-2. Then finish the runtime, MDX, and CLI chains in dependency order
-3. Run the Studio content/admin tasks in parallel as prerequisite readiness allows
-4. Keep `CMS-58` and `CMS-86` out of the MVP path because the roadmap explicitly moved them to deferred work

-# CMS-60 Studio Runtime Loader Design
-
-Date: 2026-03-21
-Task: CMS-60
-
-## Goal
-
-Specify a concrete MVP architecture for `@mdcms/studio` where the package acts as a thin runtime shell that loads a backend-served remote Studio application in `module` mode and hands off all in-app behavior to that remote runtime.
-
-## Canonical Inputs
-
-- `ROADMAP_TASKS.md` CMS-60
-- `docs/specs/README.md`
-- `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
-- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-- `packages/shared/src/lib/contracts/extensibility.ts`
-- `packages/studio/src/lib/studio-component.tsx`
-- `packages/studio/src/lib/remote-module.ts`
-- `apps/server/src/lib/studio-bootstrap.ts`
-
-## Spec Delta
-
-`SPEC-006` and `SPEC-002` need a normative runtime-model update that:
-
-- makes `module` the only supported Studio execution mode for MVP
-- removes `iframe` from the MVP decision surface instead of deferring that decision to a later spike
-- clarifies that the shell only owns bootstrap-time loading and fatal startup failure UI
-- clarifies that the remote runtime is the full Studio application after `mount(...)` succeeds
-- adds `basePath` to the shell-to-remote runtime contract so deep links resolve correctly without framework-specific router adapters
-- defines the runtime-internal composition registry contract and deterministic collision rules
-
-`ROADMAP_TASKS.md` also needs follow-up cleanup because CMS-61 currently reserves the execution-mode decision for later, which conflicts with the approved CMS-60 design direction.
-
-## Scope
-
-### In Scope
-
-- Thin `@mdcms/studio` shell loader behavior
-- Bootstrap fetch, manifest compatibility checks, runtime integrity checks, and remote module loading
-- `module`-only runtime execution
-- `basePath` handoff from shell to remote app
-- Remote-owned Studio app routing and UI state after successful mount
-- Runtime-internal composition surfaces for:
-  - `routes`
-  - `navItems`
-  - `slotWidgets`
-  - `fieldKinds`
-  - `editorNodes`
-  - `actionOverrides`
-  - `settingsPanels`
-- Deterministic collision and fallback behavior for those surfaces
-
-### Out of Scope
-
-- `iframe` execution mode
-- Host-managed Studio routing
-- SSR for the remote Studio application
-- Third-party plugin marketplace semantics
-- Dynamic per-request surface registration through the shell
-- Kill-switch and rollback hardening beyond what CMS-60 needs for startup validation
-
-## Design Decisions
-
-### 1. The Shell Is Only a Loader Host
-
-`@mdcms/studio` should only:
-
-- fetch `/api/v1/studio/bootstrap`
-- validate manifest shape, compatibility, and runtime integrity
-- load the remote runtime entry
-- construct the host bridge
-- provide `apiBaseUrl`, auth context, and `basePath`
-- call `mount(container, ctx)`
-
-The shell should not own Studio navigation, editor flows, route-level loading, or normal application rendering once the remote runtime mounts.
-
-### 2. The Remote Runtime Is the Whole Studio App
-
-The remote bundle should be treated as the full Studio application, not as a set of shell-registered fragments.
-
-Internally, the remote module can render a top-level `StudioApp` component, own its own router, and build its own composition registry, but the public boundary remains:
-
-```ts
-type RemoteStudioModule = {
-  mount: (container: HTMLElement, ctx: StudioMountContext) => () => void;
-};
-```
-
-This keeps the shell contract minimal while still allowing the remote app to be React-driven internally.
-
-### 3. `module` Is the Only MVP Execution Mode
-
-The approved direction is to remove `iframe` from MVP rather than keeping a dual-mode abstraction.
-
-The bootstrap manifest can still include a `mode` field for explicitness and compatibility, but MVP should require `mode: "module"` and reject any other value deterministically.
-
-### 4. Remote App Owns Routing After Startup
-
-The remote Studio app should own browser-path syncing with the History API:
-
-- read `window.location`
-- call `history.pushState` / `history.replaceState`
-- listen to `popstate`
-
-No framework-specific router adapter should be required beyond the host app exposing a catch-all route that renders the shell.
-
-Because deep links do not reveal the Studio subtree root reliably, the shell must provide an explicit `basePath`.
-
-### 5. `basePath` Must Be Explicit
-
-The remote runtime cannot infer whether a deep link such as `/admin/content/posts` is rooted at `/admin`, `/cms/admin`, or another embedding prefix.
-
-`StudioMountContext` should therefore gain:
-
-```ts
-type StudioMountContext = {
-  apiBaseUrl: string;
-  basePath: string;
-  auth: { mode: "cookie" | "token"; token?: string };
-  hostBridge: HostBridgeV1;
-};
-```
-
-This is the only routing input the shell needs to provide.
-
-### 6. Composition Surfaces Stay Inside the Remote Runtime
-
-The shell should not expose host-side `registerX(...)` APIs.
-
-Instead, the remote Studio app should compose its own declarative registry for:
-
-- `routes`
-- `navItems`
-- `slotWidgets`
-- `fieldKinds`
-- `editorNodes`
-- `actionOverrides`
-- `settingsPanels`
-
-This keeps CMS-60 within the first-party runtime model already described in the specs and avoids inventing a broader plugin host API prematurely.
-
-### 7. Collisions Must Be Deterministic and Fail Fast
-
-The remote runtime should validate its registry before first real render.
-
-Rules:
-
-- `routes` use normalized path matching; `/settings` and `/settings/` conflict
-- route parameter aliases that normalize to the same shape also conflict
-- duplicate `fieldKinds`, `editorNodes`, `actionOverrides`, or `settingsPanels` fail startup
-- `slotWidgets` require explicit numeric `priority`
-- `slotWidgets` sort by `priority` descending, then `id` ascending
-- `navItems` sort deterministically by explicit order, then `id`
-- `settings.sidebar` entries must reference registered `settingsPanels`
-
-### 8. Unknown Field Kinds Fallback Safely
-
-Unknown or unregistered Studio field kinds should not crash the remote app.
-
-The remote runtime should:
-
-- render a safe JSON editor fallback
-- emit a structured warning log with the missing field kind id
-- continue rendering the rest of the editor
-
-## Failure Model
-
-### Shell-Owned Fatal Startup Failures
-
-The shell is responsible only for fatal startup errors:
-
-- bootstrap fetch failed
-- bootstrap manifest invalid or incompatible
-- runtime asset load/import failed
-- remote `mount(...)` threw during startup
-
-### Remote-Owned Application Failures
-
-After `mount(...)` succeeds, the remote app owns all user-visible Studio states, including:
-
-- normal loading states
-- empty states
-- forbidden states
-- route-level errors
-- editor failures
-- application navigation
-
-## Verification
-
-Completion should be backed by:
-
-- shell loader tests for bootstrap fetch, compatibility/integrity verification, remote import, and `mount(...)` context handoff
-- shell fatal-startup tests for invalid manifest, integrity mismatch, incompatible versions, and mount failure
-- remote runtime registry tests for normalized route conflicts, duplicate surface failures, deterministic slot ordering, and unknown field-kind fallback
-- a deep-link integration test proving `basePath` handoff works under a non-root embed path
-- `bun run format:check`
-- `bun run check`
-
-## Notes
-
-- `docs/plans/` is local-only in this repository, so this design doc should remain untracked.
-- The current package layout uses `packages/studio`, even though parts of the live spec still refer to `apps/studio`; implementation planning should follow the actual repository layout.

-# CMS-60 Studio Runtime Loader Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Replace the shell-first `@mdcms/studio` embed with a thin module loader that boots a backend-served remote Studio application and enforces deterministic runtime composition rules.
-
-**Architecture:** The shell remains a small client-side host that fetches `/api/v1/studio/bootstrap`, validates the manifest and runtime bytes, creates the host bridge, passes `basePath`, and calls the remote `mount(...)` contract. The remote bundle becomes the full Studio app: it owns routing, application states, and an internal registry for `routes`, `navItems`, `slotWidgets`, `fieldKinds`, `editorNodes`, `actionOverrides`, and `settingsPanels`.
-
-**Tech Stack:** Bun, Nx, TypeScript, React 19, Node test runner, Elysia, `@mdcms/shared`, `@mdcms/studio`
-
----
-
-### Task 1: Lock the spec and operator-facing contract
-
-**Files:**
-
-- Modify: `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
-- Modify: `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-- Modify: `packages/shared/README.md`
-- Modify: `packages/studio/README.md`
-- Test: none
-
-**Step 1: Re-read the approved design and current Studio specs**
-
-Run: `sed -n '1,260p' docs/specs/SPEC-006-studio-runtime-and-ui.md && sed -n '190,360p' docs/specs/SPEC-002-system-architecture-and-extensibility.md`
-Expected: current specs still mention `iframe | module`, shell-owned UI behavior, and composition surfaces without concrete collision rules
-
-**Step 2: Update `SPEC-006` with the CMS-60 runtime-model delta**
-
-Add or update normative sections for:
-
-- `module` as the only MVP execution mode
-- shell-owned concerns limited to bootstrap, verification, and fatal startup failures
-- remote runtime as the full Studio app after `mount(...)`
-- `basePath` on `StudioMountContext`
-- remote-owned routing under the provided base path
-- composition surfaces and deterministic validation rules
-
-**Step 3: Update `SPEC-002` to match the same architecture**
-
-Remove or rewrite the parts that still defer `iframe` vs `module`, and update the runtime data flow and validation bullets so they match the approved CMS-60 design.
-
-**Step 4: Update the package READMEs**
-
-Document:
-
-- the public shell contract in `@mdcms/studio`
-- `basePath` as required loader input
-- startup-only shell failure states
-- composition-surface validation expectations in `@mdcms/shared`
-
-**Step 5: Run formatting check for the touched docs**
-
-Run: `bun run format:check`
-Expected: PASS
-
-**Step 6: Commit**
-
-```bash
-git add docs/specs/SPEC-002-system-architecture-and-extensibility.md docs/specs/SPEC-006-studio-runtime-and-ui.md packages/shared/README.md packages/studio/README.md
-git commit -m "docs(studio): specify module runtime loader contract"
-```
-
-### Task 2: Tighten the shared Studio runtime contracts
-
-**Files:**
-
-- Modify: `packages/shared/src/lib/contracts/extensibility.ts`
-- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
-- Modify: `packages/shared/src/index.ts` (only if exports need adjustment)
-- Test: `packages/shared/src/lib/contracts/extensibility.test.ts`
-
-**Step 1: Write the failing contract tests**
-
-Add cases covering:
-
-- `StudioMountContext.basePath` required and non-empty
-- bootstrap manifests reject non-`module` modes
-- compatibility helpers still validate strict version bounds
-
-**Step 2: Run the targeted shared-contract test**
-
-Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
-Expected: FAIL on missing `basePath` validation and permissive runtime-mode acceptance
-
-**Step 3: Implement the minimal contract changes**
-
-Update `extensibility.ts` so that:
-
-- `StudioExecutionMode` is `"module"`
-- `StudioMountContext` includes `basePath: string`
-- manifest validation only allows `mode: "module"`
-- existing validators and helpers keep their current error-code behavior
-
-Use a concrete contract shape such as:
-
-```ts
-export type StudioExecutionMode = "module";
-
-export type StudioMountContext = {
-  apiBaseUrl: string;
-  basePath: string;
-  auth: { mode: "cookie" | "token"; token?: string };
-  hostBridge: HostBridgeV1;
-};
-```
-
-**Step 4: Re-run the targeted shared-contract test**
-
-Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add packages/shared/src/lib/contracts/extensibility.ts packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/src/index.ts
-git commit -m "refactor(shared): lock studio runtime to module mode"

-
-### Task 3: Replace the shell-first embed with a loader host
-
-**Files:**
-
-- Modify: `packages/studio/src/lib/studio-component.tsx`
-- Create: `packages/studio/src/lib/studio-loader.ts`
-- Create: `packages/studio/src/lib/studio-loader.test.ts`
-- Modify: `packages/studio/src/index.ts`
-- Test: `packages/studio/src/lib/studio-loader.test.ts`
-
-**Step 1: Write the failing loader tests**
-
-Cover:
-
-- fetches `/api/v1/studio/bootstrap`
-- validates manifest compatibility and runtime integrity before import
-- imports the remote module from the manifest `entryUrl`
-- passes `apiBaseUrl`, `basePath`, auth, and host bridge to `mount(...)`
-- returns fatal startup state when bootstrap fetch, verification, import, or mount fails
-
-Keep the hard-to-mock logic in pure helper functions so the React component remains thin.
-
-**Step 2: Run the targeted loader test**
-
-Run: `bun test packages/studio/src/lib/studio-loader.test.ts`
-Expected: FAIL because the loader host does not exist yet
-
-**Step 3: Implement the minimal loader**
-
-Add a small loader module that:
-
-- resolves `apiBaseUrl` from `config.serverUrl`
-- fetches `/api/v1/studio/bootstrap`
-- loads runtime bytes for integrity verification
-- imports the remote module via `import(/* @vite-ignore */ entryUrl)` or equivalent dynamic ESM path
-- validates the remote contract with `assertRemoteStudioModule(...)`
-- calls `mount(container, ctx)`
-
-Update `Studio` so it becomes a client component that:
-
-- accepts `config`, `basePath`, and optional auth/host-bridge overrides for tests
-- renders only fatal startup UI while the loader is unresolved
-- delegates all normal application UI to the remote runtime after `mount(...)`
-
-**Step 4: Re-run the targeted loader test**
-
-Run: `bun test packages/studio/src/lib/studio-loader.test.ts`
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add packages/studio/src/lib/studio-component.tsx packages/studio/src/lib/studio-loader.ts packages/studio/src/lib/studio-loader.test.ts packages/studio/src/index.ts
-git commit -m "feat(studio): add remote runtime loader host"
-```
-
-### Task 4: Build the remote Studio app and runtime registry
-
-**Files:**
-
-- Modify: `packages/studio/src/lib/remote-module.ts`
-- Create: `packages/studio/src/lib/remote-studio-app.tsx`
-- Create: `packages/studio/src/lib/runtime-registry.ts`
-- Create: `packages/studio/src/lib/runtime-registry.test.ts`
-- Modify: `packages/studio/src/lib/bootstrap-verification.test.ts` (only if startup-path coverage needs extension)
-- Test: `packages/studio/src/lib/runtime-registry.test.ts`
-
-**Step 1: Write the failing runtime-registry tests**
-
-Cover:
-
-- normalized route conflicts such as `/settings` vs `/settings/`
-- param-shape conflicts such as duplicate normalized content-detail routes
-- duplicate `fieldKinds`, `editorNodes`, `actionOverrides`, and `settingsPanels`
-- `slotWidgets` missing explicit `priority`
-- deterministic slot ordering by `priority` descending then `id` ascending
-- unknown field kind falling back to a JSON editor descriptor and emitting a structured warning
-
-**Step 2: Run the targeted registry test**
-
-Run: `bun test packages/studio/src/lib/runtime-registry.test.ts`
-Expected: FAIL because the registry implementation does not exist yet
-
-**Step 3: Implement the minimal remote app and registry**
-
-Create a runtime-owned app that:
-
-- mounts from `remote-module.ts`
-- reads `ctx.basePath`
-- owns browser history and route parsing inside the remote app
-- builds and validates the composition registry before first render
-- renders the default Studio surfaces through that registry
-- uses a safe JSON editor fallback for unknown field kinds
-
-Keep the route and registry validation logic outside React where possible so tests stay deterministic and do not require a browser-heavy harness.
-
-**Step 4: Re-run the targeted registry test**
-
-Run: `bun test packages/studio/src/lib/runtime-registry.test.ts`
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add packages/studio/src/lib/remote-module.ts packages/studio/src/lib/remote-studio-app.tsx packages/studio/src/lib/runtime-registry.ts packages/studio/src/lib/runtime-registry.test.ts packages/studio/src/lib/bootstrap-verification.test.ts
-git commit -m "feat(studio): add remote studio runtime registry"
-```
-
-### Task 5: Remove shell-managed routing from the example embed and stale shell tests
-
-**Files:**
-
-- Modify: `apps/studio-example/app/admin/[[...path]]/page.tsx`
-- Modify: `packages/studio/src/lib/studio.test.ts`
-- Test: `packages/studio/src/lib/studio.test.ts`
-
-**Step 1: Write or update the failing embed tests**
-
-Refocus `studio.test.ts` around the new shell boundary:
-
-- fatal startup UI behavior only
-- no shell-managed content/document route logic after remote mount
-- `basePath` handoff into the loader path
-
-Drop assertions that are now remote-runtime responsibilities, such as shell-level route resolution and document-shell rendering.
-
-**Step 2: Run the targeted shell test**
-
-Run: `bun test packages/studio/src/lib/studio.test.ts`
-Expected: FAIL until the old shell assumptions are removed
-
-**Step 3: Update the example embed page**
-
-Change the example so it:
-
-- stops preloading route-specific Studio state in the host page
-- renders the shell with an explicit `basePath`
-- leaves routing and document loading to the remote runtime
-
-The result should be closer to:
-
-```tsx
-export default function AdminCatchAllPage() {
-  return <Studio config={config} basePath="/admin" />;
-}
-```
-
-**Step 4: Re-run the targeted shell test**
-
-Run: `bun test packages/studio/src/lib/studio.test.ts`
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add apps/studio-example/app/admin/[[...path]]/page.tsx packages/studio/src/lib/studio.test.ts
-git commit -m "refactor(studio): remove host-managed studio routing"
-```
-
-### Task 6: Verify the full CMS-60 slice
-
-**Files:**
-
-- Modify: none unless verification exposes follow-up fixes
-- Test: all touched package tests
-
-**Step 1: Run targeted Studio tests**

-
-**Step 2: Run targeted shared-contract tests**
-
-Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
-Expected: PASS
-
-**Step 3: Run formatting and workspace checks**
-
-Run: `bun run format:check && bun run check`
-Expected: PASS
-
-**Step 4: Inspect git status**
-
-Run: `git status --short`
-Expected: task-scoped tracked changes only; local-only paths such as `docs/plans/` remain unstaged
-
-**Step 5: Final commit if verification fixes were required**
-
-```bash
-git add <task-scoped-files>

-# CMS-61 Studio Runtime Decision Reconciliation Design
-
-Date: 2026-03-23
-Task: CMS-61
-
-## Goal
-
-Reconcile the stale Studio execution-mode decision record with the live module-only Studio runtime contract that is already implemented and specified elsewhere in the repository.
-
-## Canonical Inputs
-
-- `ROADMAP_TASKS.md` CMS-61
-- `docs/specs/README.md`
-- `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
-- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-- `docs/adrs/ADR-003-studio-delivery-approach-c.md`
-- `packages/studio/README.md`
-
-## Spec Delta
-
-No owning-spec delta is required for this reconciliation slice.
-
-The authoritative product contract is already module-only in the owning specs:
-
-- `SPEC-002` says Studio runtime execution is `module`-only in MVP.
-- `SPEC-006` defines `StudioExecutionMode` as `module` and states that `module` is the only supported Studio execution mode in MVP.
-
-The required delta is in the architectural rationale record:
-
-- `ADR-003` still says the execution-mode choice is open between `iframe` and `module`.
-- `ADR-003` must be reconciled so the decision record matches the live spec and current implementation direction.
-
-## Scope
-
-### In Scope
-
-- Update `ADR-003` to state that MVP execution mode is `module`.
-- Remove stale wording that leaves the execution mode undecided.
-- Keep the ADR rationale aligned with host bridge and MDX preview requirements already reflected in the specs.
-
-### Out of Scope
-
-- Any new runtime implementation work
-- Any `iframe` spike or proof-of-concept
-- Changes to the owning specs beyond confirming they already contain the final contract
-- New test coverage unless verification reveals a docs inconsistency that must be fixed
-
-## Design Decisions
-
-### 1. Treat This as ADR Reconciliation, Not Product Redesign
-
-`CMS-61` is being interpreted here as a documentation reconciliation slice only. The owning specs already carry the normative decision, so the ADR should record the same outcome instead of reopening the choice.
-
-### 2. Keep the Change Focused to `ADR-003`
-
-The smallest correct change is to update the stale ADR language in place:
-
-- replace the open decision wording with a final `module` decision
-- explain that the host bridge and MDX preview requirements fit the in-process module model for MVP
-- remove the statement that the final mode is still pending future spikes
-
-### 3. Use Existing Repo Evidence Rather Than Inventing New Spike Artifacts
-
-The repository already contains enough internal evidence for a reconciliation-only slice:
-
-- the owning specs are module-only
-- the package README is module-only
-- the runtime contracts and tests reject non-module manifests
-
-This slice should not manufacture a fake dual-mode evaluation artifact inside the codebase.
-
-## Verification
-
-Completion should be backed by:
-
-- confirming `ADR-003` no longer states the decision is open
-- confirming the canonical docs set no longer disagrees about MVP execution mode
-- `bun run format:check`
-
-## Notes
-
-- `docs/plans/` is local-only in this repository, so this design doc should remain untracked.

-# CMS-61 Studio Runtime Reconciliation Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Reconcile the stale Studio delivery ADR with the already-approved module-only Studio runtime contract.
-
-**Architecture:** This is a docs-only change. Update the ADR so its rationale and consequences match the module-only decision already owned by the live specs, then verify that no canonical docs still present the execution mode as undecided.
-
-**Tech Stack:** Markdown docs, ripgrep, Bun workspace verification commands
-
----
-
-### Task 1: Reconcile ADR-003
-
-**Files:**
-
-- Modify: `docs/adrs/ADR-003-studio-delivery-approach-c.md`
-- Verify against: `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
-- Verify against: `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-- Verify against: `packages/studio/README.md`
-
-**Step 1: Update the stale ADR language**
-
-Change the security/delivery and consequence sections so they no longer describe `iframe` vs `module` as an open MVP choice.
-
-**Step 2: Align the rationale with the live contract**
-
-State that MVP uses `module` execution because it aligns with the capability-limited host bridge, MDX preview integration, and the existing thin-loader architecture.
-
-**Step 3: Run targeted consistency checks**
-
-Run: `rg -n "decision is open|stays open|iframe.*module|execution mode remains" docs/adrs docs/specs packages/studio`
-Expected: no remaining stale open-decision wording in canonical docs for the MVP Studio execution mode
-
-**Step 4: Run format verification**
-
-Run: `bun run format:check`
-Expected: PASS
-
-**Step 5: Review git status**
-
-Run: `git status --short`
-Expected: only the intended tracked docs change is modified, and local-only files remain untracked
-
-## Notes
-
-- `docs/plans/` is local-only in this repository, so this plan should remain untracked.

-# CMS-62 Studio Runtime Hardening Design
-
-Date: 2026-03-23
-Task: CMS-62
-
-## Goal
-
-Implement the selected `module` Studio runtime path as the only production mode and add deterministic startup recovery behavior, operator disable behavior, and regression coverage for runtime validation, authorization filtering, and MDX host-bridge preview behavior.
-
-## Canonical Inputs
-
-- `ROADMAP_TASKS.md` CMS-62
-- `docs/specs/README.md`
-- `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
-- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-- `docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
-- `apps/server/README.md`
-- `packages/studio/README.md`
-
-## Spec Delta
-
-The execution mode itself does not change. The owning spec already defines MVP Studio runtime execution as `module` only.
-
-The required spec delta is the startup recovery contract:
-
-- `SPEC-006` must define server-owned publication state with `active`, optional `lastKnownGood`, and operator disable state.
-- `SPEC-006` must define bootstrap success as a startup envelope, not a raw manifest-only payload.
-- `SPEC-006` must define a deterministic recovery retry shape for client-detected runtime rejection:
-  - `rejectedBuildId`
-  - `rejectionReason` in `integrity | signature | compatibility`
-- `SPEC-006` must define deterministic disabled/unavailable outcomes:
-  - `STUDIO_RUNTIME_DISABLED`
-  - `STUDIO_RUNTIME_UNAVAILABLE`
-- `SPEC-002` should align its testing/architecture language to clarify that build selection remains server-owned and the shell only retries bootstrap once with rejection context.
-
-## Scope
-
-### In Scope
-
-- Keep `module` as the only production runtime mode.
-- Add server-owned rollback to `lastKnownGood`.
-- Add an operator kill-switch path for Studio startup.
-- Keep `/api/v1/studio/bootstrap` as the single bootstrap endpoint.
-- Add one bootstrap retry from the shell when runtime validation rejects a served build.
-- Add regression coverage for integrity/signature/compatibility rejection, fallback selection, disabled/unavailable behavior, unauthorized action visibility, forced server rejection, and MDX host-bridge preview.
-
-### Out of Scope
-
-- Any production `iframe` runtime path.
-- Browser-local caching of last-known-good builds.
-- A new admin UI or public API for toggling the kill switch.
-- A general deployment/promotion system beyond the minimum publication state required for bootstrap decisions.
-
-## Design Decisions
-
-### 1. Server Owns Publication Selection
-
-The server decides which Studio build is safe to serve. The shell never chooses between active and fallback builds on its own and never persists fallback state in the browser.
-
-Server publication state is modeled as:
-
-- `active` build
-- optional `lastKnownGood` build
-- operator `killSwitch`
-
-This preserves the existing architecture: the server publishes the Studio runtime, and the shell only validates and mounts the returned runtime.
-
-### 2. Keep a Single Bootstrap Endpoint
-
-`GET /api/v1/studio/bootstrap` remains the only startup endpoint.
-
-Initial startup request remains body-less.
-
-If the shell rejects a served build during integrity/signature/compatibility validation, it retries the same endpoint once with rejection context:
-
-- `rejectedBuildId=<buildId>`
-- `rejectionReason=integrity|signature|compatibility`
-
-The server uses that context to decide whether to serve `lastKnownGood` or return a deterministic disabled/unavailable response.
-
-### 3. Bootstrap Success Becomes a Startup Envelope
-
-Instead of returning only `{ data: StudioBootstrapManifest }`, bootstrap success returns a startup envelope:
-
-```ts
-type StudioBootstrapReadyResponse = {
-  data: {
-    status: "ready";
-    source: "active" | "lastKnownGood";
-    manifest: StudioBootstrapManifest;
-    recovery?: {
-      rejectedBuildId: string;
-      rejectionReason: "integrity" | "signature" | "compatibility";
-    };
-  };
-};
-```
-
-This keeps the public surface small while making fallback usage explicit and testable.
-
-### 4. Disabled and Unavailable Stay as Error Envelopes
-
-Bootstrap remains deterministic when Studio cannot be started:
-
-- `503 STUDIO_RUNTIME_DISABLED`
-  - operator kill switch is enabled
-- `503 STUDIO_RUNTIME_UNAVAILABLE`
-  - no safe build can be served
-
-The shell renders deterministic startup error UI for those outcomes and does not retry further.
-
-### 5. The Shell Retries Once
-
-The shell startup flow becomes:
-
-1. Fetch bootstrap.
-2. Fetch runtime asset.
-3. Validate integrity/signature/compatibility.
-4. Mount runtime if validation passes.
-5. If validation fails and the failure reason is retryable, re-request bootstrap once with rejection context.
-6. If the retry returns a ready payload, validate and mount the fallback build.
-7. If the retry returns disabled/unavailable, or if the fallback build also fails validation, render deterministic startup failure UI and stop.
-
-There is no infinite retry loop.
-
-### 6. Operator Path Is Config-Driven in MVP
-
-CMS-62 does not add a new mutation API for Studio publication control.
-
-The kill switch is server configuration or environment driven. `lastKnownGood` is the previously promoted verified publication snapshot held by the server runtime/publication layer.
-
-This satisfies the acceptance criterion without widening the operator surface beyond MVP needs.
-
-### 7. Selected-Mode Regression Coverage Must Exercise Real Host-Bridge and Authorization Paths
-
-Regression coverage should prove more than contract parsing:
-
-- the `module` mode loader handles happy-path startup
-- invalid runtime bytes/signature/compatibility trigger the one-shot bootstrap retry
-- fallback builds are served from `lastKnownGood`
-- disabled/unavailable outcomes are deterministic
-- Studio-visible actions come only from the authorization-filtered catalog
-- forced route invocation is still rejected by the server
-- the remote runtime calls `hostBridge.renderMdxPreview(...)` on the document/editor path
-
-## Implementation Notes
-
-- Shared contracts should own the new bootstrap ready envelope types and validators.
-- Server code should expose publication-state helpers without introducing circular package dependencies.
-- The remote runtime can stay thin, but it should include one minimal document-route preview surface and one minimal action strip driven by the filtered action catalog so the tests cover real selected-mode behavior.
-
-## Verification
-
-The task is complete when the repository can demonstrate:
-
-- module-only runtime behavior remains the only production path
-- bootstrap recovery is deterministic and server-owned
-- the shell retries bootstrap once on validation rejection and stops cleanly afterward
-- unauthorized actions are absent from Studio-visible action rendering and still rejected by the server when forced
-- MDX preview host-bridge flow is exercised in selected mode
-- `bun run format:check`
-- `bun run check`
-- targeted runtime regression tests in `shared`, `server`, and `studio`
-- `bun run studio:embed:smoke`
-
-## Notes

-- `docs/plans/` is local-only in this repository and must remain untracked.

-# CMS-62 Studio Runtime Hardening Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Implement server-owned Studio runtime rollback/disable behavior for the selected `module` mode and add deterministic regression coverage for bootstrap recovery, authorization-filtered action visibility, and MDX host-bridge preview.
-
-**Architecture:** Keep `module` as the only production runtime mode. The server owns Studio publication state (`active`, optional `lastKnownGood`, kill switch) and returns one bootstrap outcome at a time; the shell validates the served runtime, retries bootstrap once with rejection context on retryable validation failures, and otherwise renders deterministic startup error UI. Selected-mode regression coverage should exercise the real loader, bootstrap route, filtered action catalog, and host bridge path rather than isolated contract stubs only.
-
-**Tech Stack:** Bun, TypeScript, React 19, Elysia, shared Zod runtime contracts, node:test, Nx
-
----
-
-> Local workflow note: `docs/plans/` is local-only and must remain untracked. Do not include this plan file in commits.
-
-### Task 1: Update the spec-owned runtime recovery contract
-
-**Files:**
-
-- Modify: `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-- Modify: `docs/specs/SPEC-002-system-architecture-and-extensibility.md`
-- Modify: `packages/studio/README.md`
-- Modify: `apps/server/README.md`
-
-**Step 1: Patch the owning spec with the new bootstrap startup envelope**
-
-Add the server-owned publication state and bootstrap ready envelope to `SPEC-006`, including the retry query params and the disabled/unavailable error outcomes.
-
-```ts
-export type StudioBootstrapRejectionReason =
-  | "integrity"
-  | "signature"
-  | "compatibility";
-
-export type StudioBootstrapReadyResponse = {
-  data: {
-    status: "ready";
-    source: "active" | "lastKnownGood";
-    manifest: StudioBootstrapManifest;
-    recovery?: {
-      rejectedBuildId: string;
-      rejectionReason: StudioBootstrapRejectionReason;
-    };
-  };
-};
-```
-
-**Step 2: Align the supporting architecture and operator docs**
-
-Update `SPEC-002`, `packages/studio/README.md`, and `apps/server/README.md` so they all describe:
-
-- server-owned `active` vs `lastKnownGood`
-- one-shot bootstrap retry with rejection context
-- kill-switch via server config/env
-- `module` remaining the only production mode
-
-**Step 3: Run a targeted terminology check**
-
-Run:
-
-```bash
-rg -n "lastKnownGood|rejectedBuildId|rejectionReason|STUDIO_RUNTIME_DISABLED|STUDIO_RUNTIME_UNAVAILABLE" docs/specs/SPEC-006-studio-runtime-and-ui.md docs/specs/SPEC-002-system-architecture-and-extensibility.md packages/studio/README.md apps/server/README.md
-```
-
-Expected: each new runtime-recovery term appears in the updated docs.
-
-**Step 4: Run format verification**
-
-Run:
-
-```bash
-bun run format:check
-```
-
-Expected: PASS
-
-**Step 5: Commit the spec/docs delta**
-
-```bash
-git add docs/specs/SPEC-006-studio-runtime-and-ui.md docs/specs/SPEC-002-system-architecture-and-extensibility.md packages/studio/README.md apps/server/README.md
-git commit -m "docs(studio): define runtime recovery contract"
-```
-
-### Task 2: Add shared bootstrap startup contracts and validators
-
-**Files:**
-
-- Modify: `packages/shared/src/lib/contracts/extensibility.ts`
-- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
-- Modify: `packages/shared/src/index.ts`
-- Modify: `packages/shared/README.md`
-
-**Step 1: Write the failing shared-contract tests**
-
-Add tests for:
-
-- accepting a ready bootstrap envelope with `source: "active"`
-- accepting a fallback envelope with `source: "lastKnownGood"` and `recovery`
-- rejecting invalid `rejectionReason`
-- rejecting malformed `source`
-
-```ts
-const ready = {
-  data: {
-    status: "ready",
-    source: "lastKnownGood",
-    manifest: validManifest,
-    recovery: {
-      rejectedBuildId: "bad-build",
-      rejectionReason: "integrity",
-    },
-  },
-};
-
-assertStudioBootstrapReadyResponse(ready);
-```
-
-**Step 2: Run the targeted shared tests to verify failure**
-
-Run:
-
-```bash
-bun --cwd packages/shared test ./src/lib/contracts/extensibility.test.ts
-```
-
-Expected: FAIL because the new startup-envelope contract is not implemented yet.
-
-**Step 3: Implement the minimal shared types and runtime assertions**
-
-Add:
-
-- `StudioBootstrapRejectionReason`
-- `StudioBootstrapReadyPayload`
-- `StudioBootstrapReadyResponse`
-- `assertStudioBootstrapReadyResponse(...)`
-
-Export them through `packages/shared/src/index.ts` and document the ready-envelope contract in `packages/shared/README.md`.
-
-**Step 4: Re-run the targeted shared tests**
-
-Run:
-
-```bash
-bun --cwd packages/shared test ./src/lib/contracts/extensibility.test.ts
-```
-
-Expected: PASS
-
-**Step 5: Commit the shared-contract slice**
-
-```bash
-git add packages/shared/src/lib/contracts/extensibility.ts packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/src/index.ts packages/shared/README.md

-**Step 1: Write the failing server tests**
-
-Cover:
-
-- kill-switch env parsing
-- bootstrap returns ready envelope for `active`
-- bootstrap returns ready envelope for `lastKnownGood` when retry query params reject the active build
-- bootstrap returns `503 STUDIO_RUNTIME_DISABLED` when the kill switch is enabled
-- bootstrap returns `503 STUDIO_RUNTIME_UNAVAILABLE` when no safe build exists
-
-Example bootstrap assertion:
-
-```ts
-assert.deepEqual(body.data, {
-  status: "ready",
-  source: "lastKnownGood",
-  manifest: fallbackManifest,
-  recovery: {
-    rejectedBuildId: activeManifest.buildId,
-    rejectionReason: "integrity",
-  },
-});
-```
-
-**Step 2: Run the targeted server tests to verify failure**
-
-Run:
-
-```bash
-bun --cwd apps/server test ./src/lib/env.test.ts ./src/lib/studio-bootstrap.test.ts ./src/lib/health.test.ts ./src/lib/runtime-with-modules.test.ts
-```
-
-Expected: FAIL because the server still serves a raw manifest-only bootstrap payload and has no kill-switch/publication fallback logic.
-
-**Step 3: Implement the minimal server publication-state path**
-
-Add:
-
-- a parsed env/config flag for the operator kill switch
-- a publication-state shape in `studio-bootstrap.ts` that can hold `active` and optional `lastKnownGood`
-- bootstrap route logic in `server.ts` that:
-  - returns active ready payload on normal startup
-  - returns fallback ready payload when retry query params reject the active build and `lastKnownGood` exists
-  - returns deterministic `503` error envelopes when disabled or unavailable
-
-Do not add a new public mutation API for this task.
-
-**Step 4: Re-run the targeted server tests**
-
-Run:
-
-```bash
-bun --cwd apps/server test ./src/lib/env.test.ts ./src/lib/studio-bootstrap.test.ts ./src/lib/health.test.ts ./src/lib/runtime-with-modules.test.ts
-```
-
-Expected: PASS
-
-**Step 5: Commit the server bootstrap slice**
-
-```bash
-git add apps/server/src/lib/env.ts apps/server/src/lib/env.test.ts apps/server/src/lib/studio-bootstrap.ts apps/server/src/lib/studio-bootstrap.test.ts apps/server/src/lib/server.ts apps/server/src/lib/health.test.ts apps/server/src/lib/runtime-with-modules.test.ts
-git commit -m "feat(server): add studio runtime recovery bootstrap"
-```
-
-### Task 4: Implement shell retry-on-rejection and deterministic disabled-state UI
-
-**Files:**
-
-- Modify: `packages/studio/src/lib/studio-loader.ts`
-- Modify: `packages/studio/src/lib/studio-loader.test.ts`
-- Modify: `packages/studio/src/lib/studio-component.tsx`
-- Modify: `packages/studio/src/lib/studio.test.ts`
-
-**Step 1: Write the failing loader and shell tests**
-
-Add tests for:
-
-- parsing the new ready bootstrap envelope
-- retrying bootstrap once with `rejectedBuildId` and `rejectionReason=integrity`
-- surfacing `STUDIO_RUNTIME_DISABLED`
-- surfacing `STUDIO_RUNTIME_UNAVAILABLE`
-- stopping after one retry instead of looping
-
-Example retry expectation:
-
-```ts
-assert.deepEqual(fetchLog, [
-  "http://localhost:4000/api/v1/studio/bootstrap",
-  "http://localhost:4000/api/v1/studio/assets/active-build/runtime.mjs",
-  "http://localhost:4000/api/v1/studio/bootstrap?rejectedBuildId=active-build&rejectionReason=integrity",
-  "http://localhost:4000/api/v1/studio/assets/fallback-build/runtime.mjs",
-]);
-```
-
-**Step 2: Run the targeted studio loader tests to verify failure**
-
-Run:
-
-```bash
-bun --cwd packages/studio test ./src/lib/studio-loader.test.ts ./src/lib/studio.test.ts
-```
-
-Expected: FAIL because the loader still expects `{ data: StudioBootstrapManifest }` and has no retry/disabled logic.
-
-**Step 3: Implement the minimal loader retry path**
-
-Update the loader to:
-
-- parse `StudioBootstrapReadyResponse`
-- classify retryable validation failures as `integrity`, `signature`, or `compatibility`
-- re-request bootstrap once with rejection query params
-- stop on non-retryable failures or after a failed fallback load
-
-**Step 4: Update deterministic startup error descriptions**
-
-Extend `describeStudioStartupError(...)` and the startup shell markup so disabled/unavailable states render explicit operator-facing copy instead of falling through to generic crash text.
-
-**Step 5: Re-run the targeted studio loader tests**
-
-Run:
-
-```bash
-bun --cwd packages/studio test ./src/lib/studio-loader.test.ts ./src/lib/studio.test.ts
-```
-
-Expected: PASS
-
-**Step 6: Commit the shell recovery slice**
-
-```bash
-git add packages/studio/src/lib/studio-loader.ts packages/studio/src/lib/studio-loader.test.ts packages/studio/src/lib/studio-component.tsx packages/studio/src/lib/studio.test.ts

-
-### Task 5: Add selected-mode MDX preview and authorization-filtered action fixtures
-
-**Files:**
-
-- Modify: `packages/studio/src/lib/remote-studio-app.tsx`
-- Modify: `packages/studio/src/lib/remote-studio-app.test.ts`
-- Modify: `packages/studio/src/lib/action-catalog-adapter.ts`
-- Modify: `apps/server/src/lib/health.test.ts`
-
-**Step 1: Write the failing remote-runtime tests**
-
-Add tests that prove:
-
-- document/editor route calls `context.hostBridge.renderMdxPreview(...)`
-- preview cleanup runs on route change/unmount
-- Studio action rendering uses only the filtered catalog returned by `/api/v1/actions`
-- hidden actions do not appear in the rendered action strip
-
-Example host-bridge assertion:
-
-```ts
-assert.deepEqual(previewCalls, [
-  {
-    componentName: "HeroBanner",
-    props: { title: "Launch" },
-    key: "preview:content.document",
-  },
-]);
-```
-
-**Step 2: Run the targeted remote-runtime tests to verify failure**
-
-Run:
-
-```bash
-bun --cwd packages/studio test ./src/lib/remote-studio-app.test.ts
-```
-
-Expected: FAIL because the remote runtime does not yet exercise the host bridge or render action UI from the filtered action catalog.
-
-**Step 3: Implement the minimal remote-runtime behavior**
-
-Add:
-
-- a small document-route preview surface that calls `renderMdxPreview(...)`
-- a small action strip driven by `createStudioActionCatalogAdapter(...)`
-- deterministic loading/error fallbacks that never synthesize hidden actions locally
-
-Keep the implementation minimal and selected-mode only.
-
-**Step 4: Re-run the targeted remote-runtime tests**
-
-Run:
-
-```bash
-bun --cwd packages/studio test ./src/lib/remote-studio-app.test.ts
-```
-
-Expected: PASS
-
-**Step 5: Re-run the existing forced-invocation server test**
-
-Run:
-
-```bash
-bun --cwd apps/server test ./src/lib/health.test.ts
-```
-
-Expected: PASS, including the hidden-action forced-route rejection case.
-
-**Step 6: Commit the selected-mode fixture slice**
-
-```bash
-git add packages/studio/src/lib/remote-studio-app.tsx packages/studio/src/lib/remote-studio-app.test.ts packages/studio/src/lib/action-catalog-adapter.ts apps/server/src/lib/health.test.ts

-# CMS-68 Local MDX Component Catalog Design
-
-> Local-only planning note. This file is not canonical product documentation and should remain uncommitted.
-
-## Summary
-
-`CMS-68` should no longer be implemented as a backend schema-sync feature.
-The embedded Studio runs inside the host app and must resolve the host app's
-actual React MDX components locally. That makes component discovery, preview,
-and custom props-editor resolution a host-local runtime concern, not a server
-registry concern.
-
-## Problem
-
-The current specs drifted into a model where schema sync persists optional
-`extractedComponents` metadata on the backend and implies that Studio reads
-component registration metadata from the server.
-
-That conflicts with the approved embedding architecture:
-
-- Studio is embedded in the host app.
-- MDX preview should use the host app's real React components.
-- The backend stores MDX content and does not need to understand component
-  implementations.
-
-## Approved Direction
-
-### Source of truth
-
-`mdcms.config.ts` remains the single source of truth for MDX component
-registration.
-
-### Backend scope
-
-The backend does not persist, validate, or expose a component catalog.
-
-- Remove `extractedComponents` from the schema-sync contract.
-- Keep schema sync focused on content type registry state only.
-- Treat MDX component usage as opaque content stored in markdown/MDX bodies.
-
-### Studio runtime scope
-
-The embedded Studio runtime reads component registrations from local config and
-uses local runtime loaders for executable pieces.
-
-- Metadata for insertion/edit UI comes from `config.components`.
-- Actual preview components are resolved locally in the host bundle.
-- Custom props editors are resolved locally in the host bundle.
-
-## Public API Shape
-
-The public embed story should stay simple and avoid manual bridge plumbing or
-codegen.
-
-Supported embedding pattern:
-
-```tsx
-"use client";
-
-import { Studio } from "@mdcms/studio";
-import config from "../../../mdcms.config";
-
-export default function AdminPage() {
-  return <Studio config={config} basePath="/admin" />;
-}
-```
-
-`Studio` should accept a config object that includes MDX component metadata plus
-client-only loader callbacks on each component registration.
-
-Example authoring shape:
-
-```ts
-components: [
-  {
-    name: "Chart",
-    importPath: "@/components/mdx/Chart",
-    load: () => import("@/components/mdx/Chart").then((m) => m.Chart),
-    description: "Renders a data chart",
-    propHints: {
-      color: { widget: "color-picker" },
-    },
-  },
-  {
-    name: "PricingTable",
-    importPath: "@/components/mdx/PricingTable",
-    load: () =>
-      import("@/components/mdx/PricingTable").then((m) => m.PricingTable),
-    loadPropsEditor: () =>
-      import("@/components/mdx/PricingTable.editor").then((m) => m.default),
-    description: "Pricing table",
-  },
-];
-```
-
-## Internal Wiring
-
-The current host-bridge concept remains useful as an internal runtime boundary
-between the shell and the dynamically loaded Studio bundle, but it should not
-be user-authored boilerplate for MDX components.
-
-Implementation direction:
-
-- `@mdcms/studio` derives local MDX catalog metadata from `config.components`.
-- `@mdcms/studio` builds any internal bridge/capability objects itself.
-- The dynamically loaded Studio runtime receives:
-  - serializable MDX catalog metadata
-  - internal executable callbacks for preview/editor resolution
-
-## Consequences
-
-### Benefits
-
-- No backend component sync.
-- No component registry persistence in the database.
-- One source of truth for component registration.
-- No extra binding boilerplate beyond the authored config.
-- No code generation step.
-
-### Tradeoffs
-
-- The supported embed pattern for MDX component features becomes client-side,
-  because loader callbacks are not server-to-client serializable.
-- `mdcms.config.ts` becomes responsible for both metadata and runtime loader
-  declarations for components.
-- `createStudioEmbedConfig(...)` cannot remain the only documented path for
-  MDX-aware embedding if it strips runtime loaders away.
-
-## Required Spec Delta
-
-### SPEC-004
-
-- Remove `extractedComponents` from registry model prose.
-- Remove `extractedComponents?` from `PUT /api/v1/schema`.
-- Remove any examples that imply backend persistence of MDX component metadata.
-
-### SPEC-006
-
-- Update the embed contract to document client-side embedding for MDX component
-  features.
-- Expand the shell/runtime contract so the remote runtime receives local MDX
-  catalog metadata and internal local resolvers from the shell package, not the
-  backend.
-
-### SPEC-007
-
-- Replace "props are sent to the server" language with local embedded-Studio
-  extraction/runtime language.
-- Define the local component-catalog contract owned by the embedded Studio
-  runtime.
-- Clarify that preview and custom editor resolution are host-local concerns.
-
-## Acceptance Mapping
-
-- "Registered components are persisted and queryable by Studio" is no longer the
-  right architecture and should be reinterpreted as "registered components are
-  locally available to the embedded Studio runtime from `mdcms.config.ts`."
-- "Foundational behavior is reusable by dependent tasks" maps to:
-  - stable local component registration contract
-  - stable extracted prop metadata shape
-  - stable preview/editor loader hooks for downstream MDX tasks

-# CMS-68 Local MDX Component Catalog Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Replace the server-backed MDX component sync model with a host-local Studio component catalog sourced from `mdcms.config.ts`, while keeping the backend ignorant of component implementations.
-
-**Architecture:** Update the canonical specs first so they describe a local embedded-Studio component catalog instead of backend schema-sync persistence. Then extend the shared config contract to support client-only component loader callbacks, plumb that data through the Studio shell/runtime boundary, and delete the obsolete backend `extractedComponents` schema-sync contract and storage.
-
-**Tech Stack:** Bun, Nx, TypeScript, React, node:test, Zod, Drizzle, Markdown specs under `docs/specs/`
-
----
-
-### Task 1: Update Canonical Specs Before Code Changes
-
-**Files:**
-
-- Modify: `docs/specs/SPEC-004-schema-system-and-sync.md`
-- Modify: `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-- Modify: `docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
-- Reference: `docs/adrs/ADR-003-studio-delivery-approach-c.md`
-
-**Step 1: Edit the schema-sync spec to remove backend component catalog sync**
-
-- Remove `optional extractedComponents` from the registry model section.
-- Remove `extractedComponents?` from the `PUT /api/v1/schema` contract table.
-- Keep schema sync narrowly about content type registry state.
-
-**Step 2: Edit the Studio runtime spec to define local component catalog delivery**
-
-- Document that MDX-aware Studio embedding is client-side when loader callbacks
-  are used.
-- Document that the shell/runtime boundary carries local MDX catalog metadata
-  and local executable resolvers from the host bundle.
-- Keep the backend runtime publication model unchanged.
-
-**Step 3: Edit the MDX spec to move component extraction fully local**
-
-- Replace "sent to the server" language with "consumed by the embedded Studio
-  runtime".
-- Define the local component-catalog contract and loader responsibilities.
-- Clarify that preview and custom editor resolution happen locally in the host
-  app context.
-
-**Step 4: Review the three specs together for consistency**
-
-Run: `rg -n "extractedComponents|sent to the server|queryable by Studio|schema sync" docs/specs/SPEC-004-schema-system-and-sync.md docs/specs/SPEC-006-studio-runtime-and-ui.md docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
-
-Expected: no remaining contradictory language about backend component-catalog sync.
-
-**Step 5: Commit**
-
-```bash
-git add docs/specs/SPEC-004-schema-system-and-sync.md docs/specs/SPEC-006-studio-runtime-and-ui.md docs/specs/SPEC-007-editor-mdx-and-collaboration.md
-git commit -m "docs: move mdx component catalog to studio runtime"

-
-### Task 2: Extend Shared Config Contracts for Local Runtime Loaders
-
-**Files:**
-
-- Modify: `packages/shared/src/lib/contracts/config.ts`
-- Modify: `packages/shared/src/lib/contracts/config.test.ts`
-- Modify: `packages/shared/README.md`
-
-**Step 1: Write the failing tests for component loader authoring**
-
-Add tests in `packages/shared/src/lib/contracts/config.test.ts` that assert:
-
-- `defineConfig({... components: [...] })` accepts component registrations with
-  optional `load` and `loadPropsEditor` function fields.
-- `parseMdcmsConfig(...)` continues to normalize serializable component metadata
-  and ignores runtime-only loader callbacks.
-
-Example test shape:
-
-```ts
-test("parseMdcmsConfig ignores runtime-only component loader callbacks", () => {
-  const config = defineConfig({
-    project: "marketing-site",
-    serverUrl: "http://localhost:4000",
-    components: [
-      {
-        name: "Chart",
-        importPath: "@/components/mdx/Chart",
-        load: async () => null,
-        loadPropsEditor: async () => null,
-      },
-    ],
-  });
-
-  const parsed = parseMdcmsConfig(config);
-
-  assert.deepEqual(parsed.components, [
-    {
-      name: "Chart",
-      importPath: "@/components/mdx/Chart",
-    },
-  ]);
-});
-```
-
-**Step 2: Run the shared contract test to verify it fails**
-
-Run: `bun test packages/shared/src/lib/contracts/config.test.ts`
-
-Expected: FAIL because `MdcmsComponentRegistration` does not yet allow
-`load` / `loadPropsEditor`.
-
-**Step 3: Write the minimal shared contract changes**
-
-In `packages/shared/src/lib/contracts/config.ts`:
-
-- Extend `MdcmsComponentRegistration` with:
-  - `load?: () => Promise<unknown>`
-  - `loadPropsEditor?: () => Promise<unknown>`
-- Keep `ParsedMdcmsComponentRegistration` serializable and metadata-only.
-- Add a short code comment explaining that runtime loader callbacks are
-  host-local Studio concerns and are intentionally stripped by the shared parser.
-
-**Step 4: Run the shared contract test to verify it passes**
-
-Run: `bun test packages/shared/src/lib/contracts/config.test.ts`
-
-Expected: PASS
-
-**Step 5: Update package docs and commit**
-
-- Document the new runtime-only component loader fields in
-  `packages/shared/README.md`.
-
-```bash
-git add packages/shared/src/lib/contracts/config.ts packages/shared/src/lib/contracts/config.test.ts packages/shared/README.md
-git commit -m "feat: add local mdx component loader fields"
-```
-
-### Task 3: Change the Studio Embed Contract to Accept MDX-Aware Local Config
-
-**Files:**
-
-- Modify: `packages/studio/src/lib/studio.ts`
-- Modify: `packages/studio/src/lib/studio.test.ts`
-- Modify: `packages/studio/README.md`
-- Optional modify: `apps/studio-example/app/admin/[[...path]]/page.tsx`
-- Optional create: `apps/studio-example/app/admin/admin-studio-client.tsx`
-
-**Step 1: Write the failing tests for MDX-aware Studio config**
-
-Add tests in `packages/studio/src/lib/studio.test.ts` that assert:
-
-- `Studio` runtime config accepts raw `SharedMdcmsConfig` with component loader
-  callbacks.
-- `createStudioEmbedConfig(...)` behavior is explicitly documented:
-  - either it remains minimal metadata-only
-  - or it preserves MDX loader fields if you decide to broaden it
-- MDX component registrations are visible to downstream Studio runtime code in a
-  serializable metadata form plus runtime-local loader access.
-
-Suggested minimal test shape:
-
-```ts
-test("createStudioEmbedConfig preserves mdx component metadata needed by Studio", () => {
-  const config = createStudioEmbedConfig({
-    project: "marketing-site",
-    environment: "staging",
-    serverUrl: "http://localhost:4000",
-    components: [
-      {
-        name: "Chart",
-        importPath: "@/components/mdx/Chart",
-        load: async () => null,
-      },
-    ],
-  });
-
-  assert.equal(config.components?.[0]?.name, "Chart");
-});
-```
-
-If the final design is to let `Studio` accept the raw config directly, change
-the assertion to cover the widened `Studio` config type instead.
-
-**Step 2: Run the Studio config test to verify it fails**
-
-Run: `bun test packages/studio/src/lib/studio.test.ts`
-
-Expected: FAIL because the Studio config types currently strip components down
-to `{ project, environment, serverUrl }`.
-
-**Step 3: Implement the minimal Studio config contract**
-
-In `packages/studio/src/lib/studio.ts`:
-
-- Widen the accepted Studio config type so the shell can receive MDX component
-  registrations from `mdcms.config.ts`.
-- Decide one of these two exact implementations and document it in code:
-  - `Studio` accepts raw shared config directly and `createStudioEmbedConfig`
-    becomes optional/minimal; or
-  - `createStudioEmbedConfig` preserves the MDX component registration data
-    needed at runtime.
-
-In `packages/studio/README.md`:
-
-- Replace the server-component-only example with the approved client-side embed
-  pattern for MDX-aware Studio usage.
-- Explain that no backend component sync is required.
-
-**Step 4: Run the Studio config test to verify it passes**
-
-Run: `bun test packages/studio/src/lib/studio.test.ts`
-
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add packages/studio/src/lib/studio.ts packages/studio/src/lib/studio.test.ts packages/studio/README.md apps/studio-example/app/admin/[[...path]]/page.tsx apps/studio-example/app/admin/admin-studio-client.tsx
-git commit -m "feat: accept local mdx component config in studio"
-```

-- Test/inspect: `packages/studio/src/lib/remote-studio-app.test.ts`
-
-**Step 1: Write the failing tests for local MDX runtime delivery**
-
-Add tests that assert:
-
-- the shell builds an internal runtime capability object from `config.components`
-  without requiring user-authored bridge code
-- the runtime mount context carries MDX catalog metadata needed for insertion UI
-- preview resolution uses the local loader callbacks, not backend data
-
-Suggested loader test shape:

-
-**Step 2: Run the loader/runtime tests to verify they fail**
-
-Run: `bun test packages/studio/src/lib/studio-loader.test.ts packages/studio/src/lib/remote-studio-app.test.ts`
-
-Expected: FAIL because no MDX catalog/runtime capability plumbing exists yet.
-
-**Step 3: Implement the minimal internal resolver**
-
-- Extend the shared shell/runtime contract in
-  `packages/shared/src/lib/contracts/extensibility.ts` with the MDX catalog
-  metadata needed by the mounted runtime.
-- Keep the executable preview/editor resolver internal to `@mdcms/studio`.
-- In `packages/studio/src/lib/studio-component.tsx` and
-  `packages/studio/src/lib/studio-loader.ts`, synthesize the runtime capability
-  object from `config.components`.
-- In `packages/studio/src/lib/remote-studio-app.tsx`, consume local MDX catalog
-  metadata for insertion/edit UI instead of expecting backend data.
-
-**Step 4: Run the loader/runtime tests to verify they pass**
-
-Run: `bun test packages/studio/src/lib/studio-loader.test.ts packages/studio/src/lib/remote-studio-app.test.ts packages/shared/src/lib/contracts/extensibility.test.ts`
-
-Expected: PASS
-
-**Step 5: Commit**

-- Modify: `apps/server/README.md`
-- Modify: `apps/cli/README.md`
-
-**Step 1: Write the failing tests for removing `extractedComponents`**
-
-Update tests so they expect:
-
-- `SchemaRegistrySyncPayload` no longer accepts or documents
-  `extractedComponents`
-- server schema-sync persistence no longer writes that field
-- DB schema contract no longer includes `schema_syncs.extracted_components`
-
-Suggested schema contract test shape:
-
-```ts
-test("assertSchemaRegistrySyncPayload rejects unknown extractedComponents field", () => {
-  expectInvalidInput(
-    () =>
-      assertSchemaRegistrySyncPayload({
-        rawConfigSnapshot: {},
-        resolvedSchema: {},
-        schemaHash: "hash",
-        extractedComponents: [],
-      } as never),
-    "payload.extractedComponents",
-  );
-});
-```
-
-If the validator reports an unknown-field error differently, assert the real
-path/message shape after updating the validator.
-
-**Step 2: Run the backend/schema tests to verify they fail**
-
-Run: `bun test packages/shared/src/lib/contracts/schema.test.ts apps/server/src/lib/schema-api.test.ts`
-
-Expected: FAIL because the current contracts and server schema still accept and
-persist `extractedComponents`.
-
-**Step 3: Implement the minimal backend cleanup**
-
-- Remove `extractedComponents` from `SchemaRegistrySyncPayload`.
-- Remove DB schema/storage for `schema_syncs.extractedComponents`.
-- Remove persistence logic and test helpers that seed or assert this field.
-- Update server and CLI README files so they no longer claim component metadata
-  travels through schema sync.
-
-**Step 4: Run the backend/schema tests to verify they pass**
-
-Run: `bun test packages/shared/src/lib/contracts/schema.test.ts apps/server/src/lib/schema-api.test.ts`
-
-Expected: PASS (database-backed cases may PASS/SKIP depending on local DB
-availability, but no failures should remain)

-# CMS-69 TypeScript Prop Extraction Design
-
-> Local-only planning note. This file is not canonical product documentation and should remain uncommitted.
-
-## Summary
-
-`CMS-69` should establish a stable local prop-extraction contract for MDX
-components without inventing a browser-time reflection system or a required
-manual codegen command.
-
-The embedded Studio must receive plain serializable prop metadata, but the
-source of truth remains the host app's TypeScript component definitions. That
-means extraction belongs on a Node-side integration path in the consumer
-workspace, not in the browser and not on the backend.
-
-## Problem
-
-The current codebase has the first half of the local MDX catalog model from
-`CMS-68`:
-
-- `config.components` is the source of truth.
-- Studio can pass through `extractedProps` if somebody adds them manually.
-- The shared contract still treats `extractedProps` as `Record<string, unknown>`.
-
-What is still missing for `CMS-69`:
-
-- a normative serializable extracted-prop shape
-- deterministic filtering rules for unsupported props
-- a reusable Node-side extractor that can inspect local TypeScript source
-- a supported Studio integration path that prepares config before the client
-  shell renders
-
-Without that, downstream tasks (`CMS-70` through `CMS-74`) would build on an
-unstable pseudo-contract.
-
-## Approved Direction
-
-### Extraction boundary
-
-Prop extraction happens on a Node-side integration path in the consumer
-workspace.
-
-Supported integration points:
-
-- framework server components
-- framework/build hooks
-- dev-server hooks
-- explicit local scripts
-
-Not supported:
-
-- browser-time TypeScript inspection
-- backend-owned component-catalog sync
-- requiring editors to type raw JSON for common props
-
-### Contract ownership
-
-`@mdcms/shared` owns the serializable extracted-prop contract and its runtime
-validation rules.
-
-Planned ownership split:
-
-- `@mdcms/shared`
-  - exported `MdxExtractedProp` / `MdxExtractedProps` contract
-  - strict validation of extracted props inside Studio mount/catalog contracts
-  - a Node-only extractor subpath reusable by Studio and future CLI/tooling
-- `@mdcms/studio/runtime`
-  - a Studio-facing prepare helper that consumes raw config plus workspace
-    context and returns config enriched with `extractedProps`
-- `@mdcms/studio`
-  - continues to consume prepared serializable metadata only
-
-This keeps cross-cutting contract shape in shared while avoiding a future
-dependency from CLI tooling onto the Studio package.
-
-### Supported normalized shapes
-
-The extracted metadata should stay intentionally small and fail closed:
-
-- `string`
-- `number`
-- `boolean`
-- `date`
-- string-literal `enum`
-- `array` of `string` or `number`
-- `json` only when the developer explicitly opts the prop into a JSON editor
-  and the TypeScript shape is JSON-serializable
-- `rich-text` for `children` / `ReactNode`
-
-Requiredness is derived from declared TypeScript optionality only. The
-extractor does not inspect runtime default expressions in component bodies.
-
-### Unsupported-by-default shapes
-
-Unsupported props are omitted from `extractedProps` and hidden from the
-auto-generated Studio form:
-
-- functions and callbacks
-- refs
-- React elements/components other than `children`
-- object/record/map/set/tuple/class-instance shapes without explicit `json`
-  opt-in
-- mixed unions, intersections, unresolved generics
-- arrays whose item type is not exactly `string` or `number`
-- anything not JSON-serializable or not deterministically normalizable
-
-This keeps the contract safe and stable for `CMS-70` form mapping.
-
-### Integration model
-
-The preferred host-app flow is:
-
-1. import authored `mdcms.config.ts` on the Node side
-2. call a prepare helper that resolves component source files and extracts prop
-   metadata
-3. pass the prepared config into the client `<Studio />` shell
-
-This means the existing direct-client-import story remains acceptable for
-preview-only MDX registration, but auto-generated props editing depends on the
-prepared config path.
-
-## Consequences
-
-### Benefits
-
-- No backend coupling for MDX component metadata.
-- No required manual codegen command.
-- Stable serializable contract for downstream form/editor tasks.
-- One extractor implementation reusable by multiple local consumers.
-
-### Tradeoffs
-
-- The prepared-config path is more explicit than "just import config in a client
-  component."
-- The extractor needs TypeScript compiler access and filesystem access on the
-  Node side.
-- A new shared node-only export surface is needed so Studio and future CLI
-  flows can reuse the same extractor without depending on each other.
-
-## Spec Delta Applied
-
-The owning spec updates for this design are now in:
-
-- `docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
-- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-
-Those edits:
-
-- replace the old CLI-only extraction phrasing with a Node-side preparation
-  pipeline
-- define the normalized `MdxExtractedProp` contract
-- define fail-closed unsupported-prop filtering rules
-- clarify that browser runtime never performs TypeScript inspection
-
-## Acceptance Mapping
-
-- "Extracted schema hides functions/refs and complex unsupported props" maps to
-  the fail-closed normalization rules plus fixture coverage.
-- "Prop extraction output is stable across local MDX component-catalog
-  consumers" maps to shared contract types plus a reusable node-only extractor.
-- "Foundational behavior is documented and reusable" maps to spec deltas,
-  shared runtime validation, and runtime/helper README updates.

-# CMS-69 TypeScript Prop Extraction Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Add a deterministic Node-side MDX prop extraction pipeline that turns local TypeScript component props into stable serializable `extractedProps` metadata for Studio while filtering unsupported shapes by contract.
-
-**Architecture:** The canonical specs now define `extractedProps` as a shared serializable contract owned by `@mdcms/shared`. Implement that contract and validator in shared, add a node-only shared extractor subpath backed by the TypeScript compiler API, expose a Studio-facing prepare helper from `@mdcms/studio/runtime`, and update the Studio example/docs to pass prepared config into the client shell instead of assuming browser-time prop introspection.
-
-**Tech Stack:** Bun, Nx, TypeScript compiler API, React, node:test, Zod, Markdown specs/READMEs

-### Task 1: Lock the Shared Extracted-Prop Contract
-
-**Files:**
-
-- Modify: `packages/shared/src/lib/contracts/extensibility.ts`
-- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
-- Modify: `packages/shared/README.md`
-
-**Step 1: Write the failing contract tests**
-
-Add tests in `packages/shared/src/lib/contracts/extensibility.test.ts` that
-assert:
-
-- `assertStudioMountContext(...)` accepts MDX catalog entries whose
-  `extractedProps` values use only the allowed variants:
-  - `{ type: "string", required: false }`
-  - `{ type: "enum", required: true, values: ["bar", "line"] }`
-  - `{ type: "array", required: true, items: "number" }`
-  - `{ type: "json", required: false }`
-  - `{ type: "rich-text", required: false }`
-- invalid extracted-prop payloads are rejected:
-  - unknown `type`
-  - `array.items = "boolean"`
-  - enum with empty `values`
-  - extra keys on prop descriptors
-
-Example accepted shape:
-
-```ts
-assert.doesNotThrow(() =>
-  assertStudioMountContext({
-    apiBaseUrl: "http://localhost:4000",
-    basePath: "/admin",
-    auth: { mode: "cookie" },
-    hostBridge: validHostBridge,
-    mdx: {
-      catalog: {
-        components: [
-          {
-            name: "Chart",
-            importPath: "@/components/mdx/Chart",
-            extractedProps: {
-              title: { type: "string", required: false },
-              type: {
-                type: "enum",
-                required: true,
-                values: ["bar", "line"],
-              },
-            },
-          },
-        ],
-      },
-      resolvePropsEditor: () => null,
-    },
-  }),
-);
-```
-
-**Step 2: Run the shared contract test to verify it fails**
-
-Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
-
-Expected: FAIL because `extractedProps` is still validated as
-`Record<string, unknown>`.
-
-**Step 3: Implement the shared contract**
-
-In `packages/shared/src/lib/contracts/extensibility.ts`:
-
-- export:
-  - `MdxExtractedProp`
-  - `MdxExtractedProps`
-- replace the permissive `extractedProps: z.record(z.string(), z.unknown())`
-  with a strict schema for the approved variants
-- make enum descriptors reject empty `values`
-- keep the shape strict so unsupported keys fail validation
-
-In `packages/shared/README.md`:
-
-- document the extracted-prop variants and the purpose of the contract
-
-**Step 4: Run the shared contract test to verify it passes**
-
-Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
-
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add packages/shared/src/lib/contracts/extensibility.ts packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/README.md
-git commit -m "feat(shared): define mdx extracted prop contract"
-```
-
-### Task 2: Build the Node-Only Shared TypeScript Extractor
-
-**Files:**
-
-- Create: `packages/shared/src/lib/mdx/extracted-props.ts`
-- Create: `packages/shared/src/lib/mdx/extracted-props.test.ts`
-- Create: `packages/shared/src/lib/mdx/index.ts`
-- Modify: `packages/shared/package.json`
-- Modify: `packages/shared/README.md`
-
-**Step 1: Write the failing extractor fixture tests**
-
-Add fixture-driven tests in `packages/shared/src/lib/mdx/extracted-props.test.ts`
-that create temporary `.tsx` files and assert:
-
-- supported props extract correctly:
-  - `title?: string`
-  - `count: number`
-  - `published: boolean`
-  - `type: "bar" | "line"`
-  - `data: number[]`
-  - `tags?: string[]`
-  - `children?: ReactNode`
-- unsupported props are omitted:
-  - `onClick?: () => void`
-  - `forwardedRef?: Ref<HTMLDivElement>`
-  - `options: Record<string, string>`
-  - `pair: [number, number]`
-- `json` hint opt-in re-enables a JSON-serializable object shape:
-  - `options: { theme: string; compact: boolean }` plus
-    `propHints.options = { widget: "json" }` =>
-    `{ type: "json", required: true }`
-- non-serializable `json` opt-in still fails closed:
-  - `handlerMap: Record<string, () => void>` stays omitted even with `json`
-- requiredness follows declared TypeScript only:
-  - `title?: string` => `required: false`
-  - `title: string | undefined` => `required: false`
-  - destructuring default values do not change the extracted `required` flag
-
-Example expected output:
-
-```ts
-assert.deepEqual(result, {
-  title: { type: "string", required: false },
-  type: { type: "enum", required: true, values: ["bar", "line"] },
-  data: { type: "array", required: true, items: "number" },
-});
-```
-
-**Step 2: Run the extractor test to verify it fails**
-
-Run: `bun test packages/shared/src/lib/mdx/extracted-props.test.ts`
-
-Expected: FAIL because the extractor module does not exist yet.
-
-**Step 3: Implement the extractor**
-
-In `packages/shared/src/lib/mdx/extracted-props.ts`:
-
-- use the TypeScript compiler API to:
-  - create/load a `Program`
-  - resolve the component source file from an absolute path
-  - find the exported component symbol
-  - resolve its props type from function params or a declared props interface
-- expose a narrow API such as:
-
-```ts
-export function extractMdxComponentProps(input: {
-  filePath: string;
-  componentName: string;
-  propHints?: Record<string, unknown>;
-  tsconfigPath?: string;
-}): MdxExtractedProps;
-```
-
-- normalize only the supported shapes
-- omit everything else
-- treat `json` opt-in as allowed only for JSON-serializable shapes
-- add short comments only around the non-obvious TypeScript symbol/type walking
-
-In `packages/shared/src/lib/mdx/index.ts`:
-
-- re-export the extractor API
-
-In `packages/shared/package.json`:
-
-- add a node-oriented export such as `./mdx`
-- add `typescript` as a package dependency if the extractor imports it at runtime
-
-In `packages/shared/README.md`:
-
-- document the node-only extractor subpath briefly
-
-**Step 4: Run the extractor and contract tests**
-
-Run: `bun test packages/shared/src/lib/mdx/extracted-props.test.ts packages/shared/src/lib/contracts/extensibility.test.ts`
-
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add packages/shared/src/lib/mdx/extracted-props.ts packages/shared/src/lib/mdx/extracted-props.test.ts packages/shared/src/lib/mdx/index.ts packages/shared/package.json packages/shared/README.md
-git commit -m "feat(shared): add mdx prop extraction helper"
-```
-
-### Task 3: Add a Studio Runtime Prepare Helper and Typed Consumption Path
-
-**Files:**
-
-- Modify: `packages/studio/src/lib/studio.ts`
-- Modify: `packages/studio/src/lib/studio.test.ts`
-- Modify: `packages/studio/src/lib/studio-loader.ts`
-- Modify: `packages/studio/src/lib/studio-loader.test.ts`
-- Modify: `packages/studio/README.md`
-
-**Step 1: Write the failing Studio tests**
-
-Add tests that assert:
-
-- `@mdcms/studio/runtime` exposes a prepare helper that enriches component
-  entries with typed `extractedProps`
-- the prepare helper accepts authored config plus workspace context
-- `loadStudioRuntime(...)` reads typed `extractedProps` without the current
-  `as { extractedProps?: unknown }` escape hatch
-
-Suggested test shape in `packages/studio/src/lib/studio.test.ts`:
-
-```ts
-test("prepareStudioConfig enriches mdx component metadata from source files", async () => {
-  const config = await prepareStudioConfig(
-    {
-      project: "marketing-site",
-      environment: "staging",
-      serverUrl: "http://localhost:4000",
-      components: [
-        {
-          name: "Chart",
-          importPath: "@/components/mdx/Chart",
-        },
-      ],
-    },
-    {
-      cwd: fixtureDir,
-      resolveImportPath: (value) =>
-        value === "@/components/mdx/Chart"
-          ? join(fixtureDir, "Chart.tsx")
-          : value,
-    },
-  );
-
-  assert.deepEqual(config.components?.[0]?.extractedProps, {
-    title: { type: "string", required: false },
-  });
-});
-```
-
-And in `packages/studio/src/lib/studio-loader.test.ts`:
-
-- remove the cast-based fake component shape and assert the loader accepts the
-  prepared typed config directly
-
-**Step 2: Run the Studio tests to verify they fail**
-
-Run: `bun test packages/studio/src/lib/studio.test.ts packages/studio/src/lib/studio-loader.test.ts`
-
-Expected: FAIL because there is no prepare helper and the config types do not
-carry extracted props explicitly.
-
-**Step 3: Implement the Studio prepare helper and loader typing**
-
-In `packages/studio/src/lib/studio.ts`:
-
-- add a server-safe helper such as:
-
-```ts
-export async function prepareStudioConfig(
-  config: SharedMdcmsConfig,
-  options: {
-    cwd: string;
-    resolveImportPath?: (value: string) => string;
-    tsconfigPath?: string;
-  },
-): Promise<MdcmsConfig>;
-```
-
-- internally call the shared node-only extractor for each component entry
-- preserve authored loader callbacks and other config metadata
-- require/validate `environment` before returning the prepared config
-
-In `packages/studio/src/lib/studio-loader.ts`:
-
-- replace the untyped `readExtractedProps(...)` cast with direct typed access
-- keep the runtime consuming only serializable metadata plus local executable
-  resolvers
-
-In `packages/studio/README.md`:
-
-- update the MDX-aware embed example to show:
-  - server-side `prepareStudioConfig(...)`
-  - client-side `<Studio config={preparedConfig} ... />`
-- keep the plain runtime-helper story accurate
-
-**Step 4: Run the Studio tests to verify they pass**
-
-Run: `bun test packages/studio/src/lib/studio.test.ts packages/studio/src/lib/studio-loader.test.ts`
-
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add packages/studio/src/lib/studio.ts packages/studio/src/lib/studio.test.ts packages/studio/src/lib/studio-loader.ts packages/studio/src/lib/studio-loader.test.ts packages/studio/README.md
-git commit -m "feat(studio): prepare mdx component props locally"
-```
-
-### Task 4: Wire the Example App and Run Verification
-
-**Files:**
-
-- Modify: `apps/studio-example/app/admin/[[...path]]/page.tsx`
-- Optional create: `apps/studio-example/app/admin/admin-studio-client.tsx`
-- Optional modify: `apps/studio-example/mdcms.config.ts`
-- Reference: `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-- Reference: `docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
-
-**Step 1: Write the failing example integration assertion**
-
-Add or update a lightweight test/contract assertion that the example app can:
-
-- load raw authored config on the server side
-- prepare it before passing it to the client `Studio` shell
-
-If there is no dedicated example test yet, add a type-level assertion in
-`packages/studio/src/lib/studio.test.ts` or a focused smoke check in the example
-route source.
-
-**Step 2: Run the relevant Studio/example tests to verify they fail**
-
-Run: `bun test packages/studio/src/lib/studio.test.ts`
-
-Expected: FAIL until the example/docs use the new helper path consistently.
-
-**Step 3: Update the example integration**
-
-In the example app:
-
-- keep the route itself server-side
-- call `prepareStudioConfig(...)`
-- pass the result into a small client wrapper that renders `<Studio />`
-
-Keep the example minimal; it only needs to demonstrate the supported host-app
-integration boundary.
-
-**Step 4: Run targeted verification**
-
-Run:
-
-```bash
-bun test packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/src/lib/mdx/extracted-props.test.ts
-bun test packages/studio/src/lib/studio.test.ts packages/studio/src/lib/studio-loader.test.ts
-bun run format:check
-bun run check
-```
-
-Expected:
-
-- all targeted shared/studio tests PASS
-- `bun run format:check` PASS
-- `bun run check` PASS
-
-**Step 5: Commit**
-
-```bash
-git add apps/studio-example/app/admin/[[...path]]/page.tsx apps/studio-example/app/admin/admin-studio-client.tsx apps/studio-example/mdcms.config.ts
-git commit -m "docs(example): prepare studio config for mdx props"

-# CMS-70 Prop Type to Form Control Mapping Design
-
-> Local-only planning note. This file is not canonical product documentation and should remain uncommitted.
-
-## Summary
-
-`CMS-70` should turn the extracted local MDX prop metadata from `CMS-69` into a
-stable auto-form contract that downstream Studio/editor tasks can reuse without
-re-deriving UI decisions ad hoc.
-
-The main contract wrinkle is the URL case. The approved direction is to model
-URL as string formatting metadata, not as a new widget override. That keeps
-type extraction, default form mapping, and later widget overrides clearly
-separated.
-
-## Problem
-
-The codebase already has:
-
-- local MDX component catalog transport from host app to embedded Studio
-- deterministic TypeScript prop extraction in `@mdcms/shared`
-- fail-closed omission of unsupported props
-- a basic Studio distinction between "auto form available" and "custom props
-  editor available"
-
-What is still missing for `CMS-70`:
-
-- a shared, explicit prop-to-control mapping contract
-- a deterministic URL-input signal for string props
-- a reusable mapping helper instead of Studio-only branching
-- proof that Studio consumes the shared mapping contract rather than only
-  checking whether `extractedProps` exists
-
-Without that, `CMS-71` and `CMS-72` would have to infer control semantics from
-raw extracted prop metadata in multiple places.
-
-## Approved Direction
-
-### Contract boundary
-
-`@mdcms/shared` owns both:
-
-- the extracted MDX prop contract
-- the pure auto-form mapping helper derived from that contract
-
-`@mdcms/studio` consumes the mapping output but does not own the mapping rules.
-
-### URL handling
-
-URL is modeled as an optional format on string props:
-
-- extracted prop shape: `{ type: "string", required: boolean, format?: "url" }`
-- declaration source: `propHints.<propName>.format = "url"`
-- extraction rule: preserve the format only when the normalized prop type is
-  `string`
-
-This is intentionally not a widget. Widget overrides remain the later `CMS-71`
-concern.
-
-### Shared auto-form output
-
-Introduce a pure shared mapper that turns `MdxExtractedProps` into explicit
-auto-form field metadata. Planned default control kinds:
-
-- `string` -> `text`
-- `string` with `format: "url"` -> `url`
-- `number` -> `number`
-- `boolean` -> `boolean`
-- `enum` -> `select`
-- `array` with `items: "string"` -> `string-list`
-- `array` with `items: "number"` -> `number-list`
-- `date` -> `date`
-- `rich-text` -> `rich-text`
-
-Function and ref props remain hidden by omission upstream in extraction, which
-already matches the spec.
-
-### Studio integration scope
-
-`CMS-70` should stop short of building the full editable props UI. The Studio
-side only needs a thin proof consumer that uses the shared mapper in the
-existing hidden diagnostics/runtime test path.
-
-That keeps this task foundational and avoids bleeding into `CMS-72`.
-
-## Consequences
-
-### Benefits
-
-- One mapping source of truth for Studio and future local tooling.
-- URL inputs become deterministic without expanding the widget system early.
-- Downstream tasks can build form rendering on explicit field metadata instead
-  of reinterpreting extracted props.
-
-### Tradeoffs
-
-- The extracted prop contract grows slightly to include string formatting.
-- Shared code now owns one more MDX helper surface that needs tests and README
-  coverage.
-- The product spec must explicitly define the URL format hint before
-  implementation.
-
-## Spec Delta Required
-
-The owning spec update belongs in:
-
-- `docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
-
-Required contract delta:
-
-- define URL intent as `propHints.<propName>.format = "url"`
-- define extracted string props as optionally carrying `format: "url"`
-- define Studio mapping of `{ type: "string", format: "url" }` to a URL input
-  with validation
-- keep widget overrides limited to the existing widget list
-
-## Acceptance Mapping
-
-- "Auto-controls implement all 11 prop-type-to-form-control mappings" maps to
-  the shared mapping helper plus tests covering each supported control outcome.
-- "Foundational behavior is documented and reusable" maps to the spec delta,
-  shared contract typing, shared mapping helper exports, and README notes.
-- "Any newly introduced public contract ... is documented at the point of use"
-  maps to contract comments/README updates in the shared package.

-# CMS-70 Prop Type to Form Control Mapping Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Add a shared, deterministic MDX prop-to-form-control mapping layer that converts extracted local component prop metadata into reusable auto-form field definitions, including URL-formatted string handling, while keeping widget overrides out of scope for this task.
-
-**Architecture:** Apply the missing product contract first in `SPEC-007`, then extend the shared extracted-prop contract so string props can carry `format: "url"`. Build a pure shared mapping helper in `@mdcms/shared/mdx` that turns extracted props into explicit auto-form fields for the CMS-70 mappings only, and have Studio consume that helper in its diagnostics/test surface instead of treating any non-empty `extractedProps` object as an auto-form signal.
-
-**Tech Stack:** Bun, Nx, TypeScript, node:test, Zod, React, Markdown specs/READMEs
-
----
-
-### Task 1: Apply the Owning Spec Delta
-
-**Files:**
-
-- Modify: `docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
-
-**Step 1: Update the spec prose before code**
-
-Edit `docs/specs/SPEC-007-editor-mdx-and-collaboration.md` so it explicitly
-defines:
-
-- `propHints.<propName>.format = "url"` as the URL intent signal
-- `MdxExtractedProp` string descriptors may carry optional `format: "url"`
-- `{ type: "string", format: "url" }` maps to a URL input with validation
-- this is not a widget and does not expand the widget list in the later
-  override section
-
-Suggested contract snippet:
-
-```ts
-export type MdxExtractedProp =
-  | { type: "string"; required: boolean; format?: "url" }
-  | { type: "number"; required: boolean }
-  | { type: "boolean"; required: boolean }
-  | { type: "date"; required: boolean }
-  | { type: "enum"; required: boolean; values: string[] }
-  | { type: "array"; required: boolean; items: "string" | "number" }
-  | { type: "json"; required: boolean }
-  | { type: "rich-text"; required: boolean };
-```
-
-**Step 2: Verify the spec wording matches the approved direction**
-
-Run: `rg -n "format: \"url\"|URL input with validation|not a widget" docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
-
-Expected: the owning spec now contains all three concepts.
-
-**Step 3: Commit**
-
-```bash
-git add docs/specs/SPEC-007-editor-mdx-and-collaboration.md
-git commit -m "docs(specs): clarify mdx url format mapping"
-```
-
-### Task 2: Extend the Shared Extracted-Prop Contract
-
-**Files:**
-
-- Modify: `packages/shared/src/lib/contracts/extensibility.ts`
-- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
-- Modify: `packages/shared/README.md`
-
-**Step 1: Write the failing contract tests**
-
-Add tests in `packages/shared/src/lib/contracts/extensibility.test.ts` that
-assert:
-
-- a string descriptor with `format: "url"` is accepted
-- non-string descriptors with `format: "url"` are rejected
-- unsupported format values are rejected
-- existing valid descriptors still pass unchanged
-
-Example accepted payload:
-
-```ts
-extractedProps: {
-  website: {
-    type: "string",
-    required: false,
-    format: "url",
-  },
-}
-```
-
-Example rejected payloads:
-
-```ts
-extractedProps: {
-  publishedAt: {
-    type: "date",
-    required: false,
-    format: "url",
-  },
-}
-```
-
-```ts
-extractedProps: {
-  title: {
-    type: "string",
-    required: true,
-    format: "email",
-  },
-}
-```
-
-**Step 2: Run the contract test to verify it fails**
-
-Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
-
-Expected: FAIL because the validator does not permit `format` on string props
-yet.
-
-**Step 3: Implement the contract change**
-
-In `packages/shared/src/lib/contracts/extensibility.ts`:
-
-- extend the `MdxExtractedProp` TypeScript union so only string props can carry
-  optional `format: "url"`
-- update the Zod schema for extracted props to mirror that shape strictly
-- keep all descriptor objects strict so extra keys still fail validation
-
-In `packages/shared/README.md`:
-
-- document the string `format: "url"` option and clarify that it drives default
-  auto-form behavior rather than the widget override system
-
-**Step 4: Run the contract test to verify it passes**
-
-Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
-
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add packages/shared/src/lib/contracts/extensibility.ts packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/README.md
-git commit -m "feat(shared): add mdx string format metadata"
-```
-
-### Task 3: Preserve URL Format During Prop Extraction
-
-**Files:**
-
-- Modify: `packages/shared/src/lib/mdx/extracted-props.ts`
-- Modify: `packages/shared/src/lib/mdx/extracted-props.test.ts`
-
-**Step 1: Write the failing extraction tests**
-
-Add tests in `packages/shared/src/lib/mdx/extracted-props.test.ts` that cover:
-
-- `string` prop plus `propHints.website = { format: "url" }` extracts as
-  `{ type: "string", required: ..., format: "url" }`
-- the same hint on `number`, `date`, `enum`, `array`, or `rich-text` is ignored
-- unsupported hint values do not leak into extracted output
-
-Example fixture:
-
-```tsx
-export interface LinkCardProps {
-  title: string;
-  website?: string;
-}
-
-export function LinkCard(_props: LinkCardProps) {
-  return null;
-}
-```
-
-Example expected output:
-
-```ts
-{
-  title: { type: "string", required: true },
-  website: { type: "string", required: false, format: "url" },
-}
-```
-
-**Step 2: Run the extractor test to verify it fails**
-
-Run: `bun test packages/shared/src/lib/mdx/extracted-props.test.ts`
-
-Expected: FAIL because extracted string props do not preserve `format` yet.
-
-**Step 3: Implement the extraction logic**
-
-In `packages/shared/src/lib/mdx/extracted-props.ts`:
-
-- add a narrow helper such as `getStringFormat(propHint)` that returns `"url"`
-  only when:
-  - the hint is an object
-  - `format === "url"`
-- apply that helper only inside the `string` normalization branch
-- ignore `format` hints for all non-string normalized prop shapes
-
-Keep the function fail-closed. Invalid or irrelevant hints should not throw and
-should not alter the extracted descriptor.
-
-**Step 4: Run the extractor and contract tests**
-
-Run: `bun test packages/shared/src/lib/mdx/extracted-props.test.ts packages/shared/src/lib/contracts/extensibility.test.ts`
-
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add packages/shared/src/lib/mdx/extracted-props.ts packages/shared/src/lib/mdx/extracted-props.test.ts
-git commit -m "feat(shared): preserve mdx url string hints"
-```
-
-### Task 4: Add the Shared Auto-Form Mapping Helper
-
-**Files:**
-
-- Create: `packages/shared/src/lib/mdx/auto-form.ts`
-- Create: `packages/shared/src/lib/mdx/auto-form.test.ts`
-- Modify: `packages/shared/src/lib/mdx/index.ts`
-- Modify: `packages/shared/README.md`
-
-**Step 1: Write the failing mapping tests**
-
-Create `packages/shared/src/lib/mdx/auto-form.test.ts` with coverage for all
-CMS-70 mappings:
-
-- `string` -> `text`
-- `string` + `format: "url"` -> `url`
-- `number` -> `number`
-- `boolean` -> `boolean`
-- `enum` -> `select`
-- `array:string` -> `string-list`
-- `array:number` -> `number-list`
-- `date` -> `date`
-- `rich-text` -> `rich-text`
-
-Also assert:
-
-- field output is deterministic and preserves input property iteration order
-- `json` extracted props are omitted for now
-- empty input returns `[]`
-
-Suggested public shape:
-
-```ts
-type MdxAutoFormField =
-  | { name: string; control: "text"; required: boolean }
-  | { name: string; control: "url"; required: boolean }
-  | { name: string; control: "number"; required: boolean }
-  | { name: string; control: "boolean"; required: boolean }
-  | { name: string; control: "select"; required: boolean; options: string[] }
-  | { name: string; control: "string-list"; required: boolean }
-  | { name: string; control: "number-list"; required: boolean }
-  | { name: string; control: "date"; required: boolean }
-  | { name: string; control: "rich-text"; required: boolean };
-```
-
-**Step 2: Run the mapping test to verify it fails**
-
-Run: `bun test packages/shared/src/lib/mdx/auto-form.test.ts`
-
-Expected: FAIL because the helper module does not exist yet.
-
-**Step 3: Implement the mapping helper**
-
-In `packages/shared/src/lib/mdx/auto-form.ts`:
-
-- export the `MdxAutoFormField` type
-- export a pure function such as:
-
-```ts
-export function createMdxAutoFormFields(
-  extractedProps: MdxExtractedProps | undefined,
-): MdxAutoFormField[];
-```
-
-- switch on each extracted prop variant and return the mapped control
-- skip `json` props for this task so CMS-71 can own the widget override path
-- preserve deterministic order by iterating `Object.entries(extractedProps)`
-
-In `packages/shared/src/lib/mdx/index.ts`:
-
-- export the new helper/types
-
-In `packages/shared/README.md`:
-
-- add a short section describing `createMdxAutoFormFields(...)` and the default
-  controls it emits
-
-**Step 4: Run the shared MDX tests**
-
-Run: `bun test packages/shared/src/lib/mdx/extracted-props.test.ts packages/shared/src/lib/mdx/auto-form.test.ts`
-
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add packages/shared/src/lib/mdx/auto-form.ts packages/shared/src/lib/mdx/auto-form.test.ts packages/shared/src/lib/mdx/index.ts packages/shared/README.md
-git commit -m "feat(shared): add mdx auto form mapping"
-```
-
-### Task 5: Wire the Shared Mapper into Studio Diagnostics
-
-**Files:**
-
-- Modify: `packages/studio/src/lib/remote-studio-app.tsx`
-- Modify: `packages/studio/src/lib/remote-studio-app.test.ts`
-
-**Step 1: Write the failing Studio test**
-
-Update `packages/studio/src/lib/remote-studio-app.test.ts` so the document-route
-diagnostics assert explicit mapped control metadata rather than only the
-presence of `extractedProps`.
-
-For example, expect rendered markers such as:
-
-```html
-<span data-mdcms-mdx-auto-form="Chart">Auto form</span>
-<span data-mdcms-mdx-auto-control="Chart:title:text"></span>
-<span data-mdcms-mdx-auto-control="Chart:website:url"></span>
-```
-
-Also add a component whose extracted props contain only `json` and assert it
-does not render the auto-form marker yet.
-
-**Step 2: Run the Studio test to verify it fails**
-
-Run: `bun test packages/studio/src/lib/remote-studio-app.test.ts`
-
-Expected: FAIL because the runtime currently treats any non-empty
-`extractedProps` object as an auto-form signal.
-
-**Step 3: Implement the Studio consumer**
-
-In `packages/studio/src/lib/remote-studio-app.tsx`:
-
-- import `createMdxAutoFormFields` from `@mdcms/shared/mdx`
-- replace `hasGeneratedPropsEditor(...)` with a helper that builds mapped fields
-  and checks `fields.length > 0`
-- expose the mapped control kinds on the hidden diagnostics surface so the test
-  can prove Studio is using the shared mapping contract
-
-Keep this diagnostic-only. Do not build the full props form UI in this task.
-
-**Step 4: Run the Studio test to verify it passes**
-
-Run: `bun test packages/studio/src/lib/remote-studio-app.test.ts`
-
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add packages/studio/src/lib/remote-studio-app.tsx packages/studio/src/lib/remote-studio-app.test.ts
-git commit -m "feat(studio): consume mdx auto form mappings"
-```
-
-### Task 6: Run End-to-End Verification
-
-**Files:**
-
-- Modify: none
-
-**Step 1: Run focused package tests**
-
-Run:
-
-```bash
-bun test packages/shared/src/lib/contracts/extensibility.test.ts
-bun test packages/shared/src/lib/mdx/extracted-props.test.ts
-bun test packages/shared/src/lib/mdx/auto-form.test.ts
-bun test packages/studio/src/lib/remote-studio-app.test.ts
-```
-
-Expected: all PASS
-
-**Step 2: Run workspace formatting check**
-
-Run: `bun run format:check`
-
-Expected: PASS
-
-**Step 3: Run workspace baseline check**
-
-Run: `bun run check`
-
-Expected: PASS
-
-**Step 4: Inspect git status**
-
-Run: `git status --short`
-
-Expected:
-
-- only CMS-70 code/spec files are staged or modified
-- local-only files remain unstaged and uncommitted:
-  - `AGENTS.md`
-  - `ROADMAP_TASKS.md`
-  - `docs/plans/`
-
-**Step 5: Final commit**
-
-```bash
-git add docs/specs/SPEC-007-editor-mdx-and-collaboration.md packages/shared/src/lib/contracts/extensibility.ts packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/src/lib/mdx/extracted-props.ts packages/shared/src/lib/mdx/extracted-props.test.ts packages/shared/src/lib/mdx/auto-form.ts packages/shared/src/lib/mdx/auto-form.test.ts packages/shared/src/lib/mdx/index.ts packages/shared/README.md packages/studio/src/lib/remote-studio-app.tsx packages/studio/src/lib/remote-studio-app.test.ts

-# Studio UI Runtime Mock Integration Design
-
-Date: 2026-03-25
-Task: CMS-47 + CMS-48 follow-on Studio UI integration
-
-## Goal
-
-Replace the current remote Studio placeholder UI with the approved `./studio_ui` admin mock inside the real `@mdcms/studio` runtime so visiting `/admin` in the host app renders the new Studio shell and route set through the existing bootstrap/runtime-delivery path.
-
-## Canonical Inputs
-
-- `ROADMAP_TASKS.md` CMS-47, CMS-48, CMS-49, CMS-50
-- `docs/specs/README.md`
-- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-- `packages/studio/README.md`
-- `packages/studio/src/lib/build-runtime.ts`
-- `packages/studio/src/lib/remote-module.ts`
-- `packages/studio/src/lib/remote-studio-app.tsx`
-- `packages/studio/src/lib/remote-studio-app.test.ts`
-- `apps/studio-example/app/admin/[[...path]]/page.tsx`
-- `apps/studio-example/README.md`
-- `studio_ui/`
-
-## Spec Delta
-
-`SPEC-006` already owns the Studio embed shell and these runtime routes:
-
-- `/admin`
-- `/admin/content`
-- `/admin/content/:type`
-- `/admin/content/:type/:documentId`
-- `/admin/environments`
-- `/admin/users`
-- `/admin/settings`
-- `/admin/trash`
-
-The approved mock adds runtime-owned admin pages that are not yet specified in
-the owning spec:
-
-- `/admin/media`
-- `/admin/schema`
-- `/admin/workflows`
-- `/admin/api`
-
-The required spec delta is narrow:
-
-- add those four routes to `SPEC-006` as Studio runtime-owned navigable
-  surfaces
-- define this phase as shell-only/mock rendering for those pages
-- keep live backend contracts and mutations for those pages deferred to their
-  future owning work
-- explicitly keep mock auth pages out of scope because Studio auth remains
-  governed by `SPEC-005` and the host embed flow in `SPEC-006`
-
-## Scope
-
-### In Scope
-
-- Port the admin mock route set into `packages/studio`
-- Keep the existing bootstrap, verification, and remote-module mount flow
-- Replace Next-specific routing helpers with runtime-local navigation helpers
-- Add a runtime-owned styling path so the remote bundle renders independently of
-  host-app CSS
-- Keep mock data, stub actions, and local-only state where backend wiring is not
-  part of this slice
-- Update tests so `/admin/*` routes are asserted through the real remote runtime
-
-### Out of Scope
-
-- Wiring mock pages to live backend contracts beyond what already exists
-- Reworking the host-app embed architecture in `apps/studio-example`
-- Porting `(auth)` pages from `studio_ui`
-- Making `/admin/media`, `/admin/schema`, `/admin/workflows`, or `/admin/api`
-  functional beyond the approved shell-only placeholders
-- Introducing new server endpoints or mutation contracts for the placeholder
-  pages
-
-## Design Decisions
-
-### 1. Keep the Real Runtime Boundary Intact
-
-The host app should keep mounting `@mdcms/studio` at `/admin/*` through the
-existing catch-all route. The visible UI change should come from updating the
-remote runtime bundle in `packages/studio`, not from bypassing the runtime and
-rendering the mock directly in `apps/studio-example`.
-
-This preserves the architecture already defined in `SPEC-006`:
-
-- shell fetches bootstrap
-- shell verifies runtime
-- shell loads remote module
-- remote runtime owns the Studio UI after `mount(...)`
-
-### 2. Port Only the Admin Runtime Surfaces
-
-The `studio_ui` project contains both admin and auth pages. Only the admin route
-set should move into the remote runtime. Auth remains outside the Studio runtime
-surface and should continue to be owned by the host/server auth stack.
-
-### 3. Replace Next Router APIs With Runtime-Local Navigation
-
-The mock currently depends on:
-
-- `next/link`
-- `next/navigation`
-- `next/font`
-
-The runtime port should replace those with:
-
-- a base-path-aware link component that uses `history.pushState`
-- pathname/params helpers backed by the remote runtime router state
-- plain CSS font stacks instead of Next font loaders
-
-This keeps the runtime bundle framework-agnostic once it is mounted.
-
-### 4. Add a Runtime-Owned CSS Asset Path
-
-The current remote runtime uses inline styles, while the mock uses Tailwind v4
-utility classes and a global token sheet.
-
-The port should add a dedicated runtime styling path:
-
-- keep the mock's token system and visual language
-- compile the runtime stylesheet as a Studio asset during `build-runtime`
-- derive the stylesheet URL from the remote module URL so the mounted runtime
-  can install its own styles without host-app participation
-
-This avoids coupling the Studio UI to host-app Tailwind configuration.
-
-### 5. Port Selectively, Not Blindly
-
-Only the components actually needed by the approved route set should move into
-`packages/studio`:
-
-- shared admin layout
-- sidebar/header/shell state
-- mock data and view helpers
-- route page components
-- only the shadcn/Radix primitives used by those pages
-- editor components needed for the document route
-
-This keeps the first integration pass focused while still delivering the whole
-approved route set.
-
-### 6. Keep Backend Wiring Deferred But Shape the Runtime for It
-
-Mock data is acceptable in this phase, but the port should keep clean seams for
-future backend work:
-
-- route-level page components should accept data via small local selectors or
-  adapters rather than reading globals everywhere
-- extra placeholder pages should remain obvious shell surfaces, not pretend to
-  be wired features
-- role visibility rules should already exist for admin-only surfaces so later
-  real auth/session wiring can slot into the same structure
-
-## Verification
-
-Completion should be backed by:
-
-- spec/doc updates for the extra Studio pages
-- runtime build tests covering emitted CSS assets
-- remote runtime tests covering:
-  - route matching for the expanded `/admin/*` set
-  - local navigation helpers
-  - route rendering titles for the ported pages
-  - role-aware nav visibility where applicable
-- loader tests proving bootstrap/mount behavior remains unchanged
-- host smoke verification so `http://127.0.0.1:4173/admin` renders the new UI
-- `bun run format:check`
-- `bun run check`
-
-## Notes
-
-- `docs/plans/` is local-only in this repository and must remain untracked.
-- The current repository layout uses `packages/studio`, not `apps/studio`, so
-  implementation should follow the actual workspace boundaries.
-- `ROADMAP_TASKS.md` and `SPEC-006` are aligned for the existing route set, but
-  the extra mock pages need the spec patch before implementation starts.

-# Studio UI Runtime Mock Integration Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Port the approved `studio_ui` admin mock into the real `@mdcms/studio` remote runtime so `/admin/*` in the host app renders the new Studio UI through the existing bootstrap/runtime path.
-
-**Architecture:** Keep the current `@mdcms/studio` shell, bootstrap verification, and remote module loading intact. Update the owning spec first for the extra mock-only admin pages, then add a runtime-owned CSS asset path, base-path-aware navigation helpers, and a selective port of the admin shell/pages into `packages/studio` with mock data preserved for now.
-
-**Tech Stack:** Bun, TypeScript, React 19, Next host app, Tailwind v4 runtime stylesheet build, Radix UI primitives, TipTap, node:test, Nx
-
----
-
-> Local workflow note: `docs/plans/` is local-only and must remain untracked. Do not include this plan file in commits.
-
-### Task 1: Patch the owning spec and point-of-use docs for the expanded admin route set
-
-**Files:**
-
-- Modify: `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-- Modify: `packages/studio/README.md`
-- Modify: `apps/studio-example/README.md`
-
-**Step 1: Write the spec delta for the extra mock-backed admin pages**
-
-Add `/admin/media`, `/admin/schema`, `/admin/workflows`, and `/admin/api` to
-the Studio internal route list in `SPEC-006`, and describe them as
-runtime-owned navigable surfaces that are allowed to render shell-only/mock
-content in this phase.
-
-```md
-- `/admin/media` - Media library shell surface
-- `/admin/schema` - Schema explorer shell surface
-- `/admin/workflows` - Workflow shell surface
-- `/admin/api` - API playground shell surface
-```
-
-**Step 2: Align the runtime package and host-app docs**
-
-Update `packages/studio/README.md` and `apps/studio-example/README.md` so both
-documents describe the expanded `/admin/*` route set and clarify that the
-additional pages are present as UI surfaces before backend wiring lands.
-
-**Step 3: Run a targeted terminology check**
-
-Run:
-
-```bash
-rg -n "/admin/media|/admin/schema|/admin/workflows|/admin/api|shell-only|mock content" docs/specs/SPEC-006-studio-runtime-and-ui.md packages/studio/README.md apps/studio-example/README.md
-```
-
-Expected: each new route appears in the updated docs.
-
-**Step 4: Run format verification**
-
-Run:
-
-```bash
-bun run format:check
-```
-
-Expected: PASS
-
-**Step 5: Commit the spec/docs delta**
-
-```bash
-git add docs/specs/SPEC-006-studio-runtime-and-ui.md packages/studio/README.md apps/studio-example/README.md
-git commit -m "docs(studio): define expanded admin route surfaces"
-```
-
-### Task 2: Add a runtime-owned stylesheet asset path for the remote Studio bundle
-
-**Files:**
-
-- Modify: `packages/studio/package.json`
-- Modify: `packages/studio/src/lib/build-runtime.ts`
-- Modify: `packages/studio/src/lib/build-runtime.test.ts`
-- Modify: `packages/studio/src/lib/remote-module.ts`
-- Create: `packages/studio/src/lib/runtime-ui/styles.css`
-- Create: `packages/studio/src/lib/runtime-ui/style-installer.ts`
-- Create: `packages/studio/src/lib/runtime-ui/style-installer.test.ts`
-
-**Step 1: Write the failing runtime-style tests**
-
-Add tests that assert:
-
-- `buildStudioRuntimeArtifacts(...)` emits a CSS asset next to the JS entry
-- the emitted CSS filename is derived from the same `buildId`
-- `mount(...)` installs the stylesheet once and cleans up correctly on unmount
-
-```ts
-assert.match(result.cssFile, /^studio-runtime\.[a-f0-9]{16}\.css$/);
-assert.equal(installedLinks[0]?.href.endsWith(result.cssFile), true);
-```
-
-**Step 2: Run the targeted tests to verify failure**
-
-Run:
-
-```bash
-bun --cwd packages/studio test ./src/lib/build-runtime.test.ts ./src/lib/runtime-ui/style-installer.test.ts
-```
-
-Expected: FAIL because the runtime build currently emits only the JS module.
-
-**Step 3: Implement the minimal CSS asset pipeline**
-
-Update `build-runtime.ts` so it also emits a compiled stylesheet asset, and add
-a small installer helper that derives the CSS URL from `import.meta.url` when
-the remote runtime mounts.
-
-```ts
-const stylesheetUrl = new URL(
-  import.meta.url.replace(/\.mjs$/, ".css"),
-).toString();
-
-const removeStyles = installStudioRuntimeStyles(stylesheetUrl);
-```
-
-Keep the first pass simple: one global runtime stylesheet asset owned by
-`@mdcms/studio`.
-
-**Step 4: Re-run the targeted tests**
-
-Run:
-
-```bash
-bun --cwd packages/studio test ./src/lib/build-runtime.test.ts ./src/lib/runtime-ui/style-installer.test.ts
-```
-
-Expected: PASS
-
-**Step 5: Commit the runtime-style slice**
-
-```bash
-git add packages/studio/package.json packages/studio/src/lib/build-runtime.ts packages/studio/src/lib/build-runtime.test.ts packages/studio/src/lib/remote-module.ts packages/studio/src/lib/runtime-ui/styles.css packages/studio/src/lib/runtime-ui/style-installer.ts packages/studio/src/lib/runtime-ui/style-installer.test.ts
-git commit -m "feat(studio): add remote runtime stylesheet assets"
-```
-
-### Task 3: Add runtime-local navigation primitives and admin-shell state

-- Create: `packages/studio/src/lib/runtime-ui/coming-soon.tsx`
-
-**Step 1: Write the failing runtime-shell tests**
-
-Cover:
-
-- matching and rendering the expanded route set
-- base-path-aware `navigate(...)` behavior
-- active-nav highlighting under `/admin/*`
-- role-aware nav visibility for admin-only pages
-
-```ts
-assert.equal(matchStudioRoute("/api", routes)?.id, "api");
-assert.match(markup, /data-mdcms-nav-item="settings"/);
-assert.doesNotMatch(viewerMarkup, /data-mdcms-nav-item="users"/);
-```
-
-**Step 2: Run the targeted remote-runtime tests to verify failure**
-
-Run:
-
-```bash
-bun --cwd packages/studio test ./src/lib/remote-studio-app.test.ts
-```
-
-Expected: FAIL because the current remote runtime still renders the placeholder
-registry demo.
-
-**Step 3: Implement the local navigation and shell foundations**
-
-Add a small runtime router state layer and use it to power a reusable admin
-layout, sidebar, header, and shared mock-data selectors.
-
-```tsx
-const { pathname, navigate } = useStudioNavigation(context.basePath);
-
-return (
-  <StudioNavigationProvider value={{ pathname, navigate }}>
-    <AdminLayout>{children}</AdminLayout>
-  </StudioNavigationProvider>
-);
-```
-
-Keep `next/link`, `next/navigation`, and `next/font` out of the runtime port.
-
-**Step 4: Re-run the targeted tests**
-
-Run:
-
-```bash
-bun --cwd packages/studio test ./src/lib/remote-studio-app.test.ts
-```
-
-Expected: PASS

-- Create: `packages/studio/src/lib/runtime-ui/ui/tooltip.tsx`
-
-**Step 1: Write the failing editor and primitive smoke tests**
-
-Add one small rendering test that mounts the document route and asserts the
-ported editor/sidebar surfaces and core primitives render without throwing.
-
-```ts
-assert.match(markup, /Document Editor/);
-assert.match(markup, /data-mdcms-editor-sidebar/);
-```
-
-**Step 2: Run the targeted tests to verify failure**
-
-Run:
-
-```bash
-bun --cwd packages/studio test ./src/lib/remote-studio-app.test.ts
-```
-
-Expected: FAIL because the route components and their primitive dependencies do
-not exist yet.
-
-**Step 3: Port the minimal component set used by the admin pages**
-
-Copy only the primitives and editor surfaces referenced by the approved page
-set. Trim mock-only dependencies that are not used by those pages, and prefer a
-small local theme toggle over bringing `next-themes` into the runtime.
-
-```tsx
-export function StudioButton(props: ButtonHTMLAttributes<HTMLButtonElement>) {
-  return <button data-slot="button" {...props} />;
-}
-```
-
-Update `packages/studio/package.json` with the exact Radix, icon, and TipTap
-runtime dependencies required by this subset.
-
-**Step 4: Re-run the targeted tests**
-
-Run:
-
-```bash

-
-Run:
-
-```bash
-bun --cwd packages/studio test ./src/lib/remote-studio-app.test.ts

-
-Expected: FAIL because the runtime still renders placeholder surfaces or is

-
-**Step 3: Port the page components and update the route registry**
-
-Wire the new page components into the remote runtime route map and keep the

-
-**Step 1: Add the final regression tests**
-
-Cover:
-
-- loader behavior still mounts the remote runtime with the same context

-Expected: PASS
-
-**Step 3: Run workspace verification**
-
-Run:
-
-```bash
-bun run format:check
-bun run check
-bun run studio:embed:smoke
-```
-
-Expected: PASS for all three commands, and the smoke check should prove that
-`http://127.0.0.1:4173/admin` renders the new Studio runtime instead of the old
-placeholder.
-
-**Step 4: Update any remaining point-of-use docs**
-
-If the runtime README or smoke-app README still describe the old placeholder UI,
-patch them now so the embed workflow docs match reality.
-
-**Step 5: Commit the verification/docs slice**
-
-```bash
-git add packages/studio/README.md apps/studio-example/README.md packages/studio/src/lib/studio-loader.test.ts packages/studio/src/lib/studio.test.ts

-# CMS-71 and CMS-72 Widget Hints and Custom Editors Design
-
-> Local-only planning note. This file is not canonical product documentation and should remain uncommitted.
-
-## Summary
-
-Combine `CMS-71` and `CMS-72` into one spec-first slice that:
-
-- formalizes the shared `propHints` contract and override precedence
-- validates widget-hint config during local MDX catalog preparation
-- extends the shared auto-form mapping helper so widget hints can override
-  default controls deterministically
-- introduces a Studio-side custom props editor host lifecycle that resolves
-  editors lazily and exposes `loading`, `ready`, `empty`, `error`, and
-  `forbidden` states without pulling in the full `CMS-74` node-view editor UX
-
-## Problem
-
-The current codebase already has:
-
-- local MDX component catalog transport from host config into the embedded
-  Studio runtime
-- extracted prop metadata for default auto-form generation
-- `propHints` passed through as opaque metadata
-- `resolvePropsEditor(componentName)` wired as a synchronous presence check in
-  the runtime diagnostics path
-
-What is still missing:
-
-- a typed and validated `propHints` contract
-- a shared precedence rule between default controls, widget overrides, and
-  `propsEditor`
-- support for all seven widget overrides in the shared MDX mapping layer
-- an actual custom-editor resolution lifecycle with defined UI states and
-  read-only behavior
-
-Without that, downstream work would keep reinterpreting raw `propHints` objects
-inside Studio code, and `CMS-72` would still not have a contract for how custom
-editor loading and failure behave.
-
-## Approved Direction
-
-### Spec ownership
-
-`SPEC-007` remains the owning product contract for both tasks. The required
-spec delta is:
-
-- define a typed `propHints` union
-- define validation rules per widget
-- define deterministic precedence across `propsEditor`, widget hints, and
-  default prop-type mapping
-- define the custom props editor lifecycle states and read-only behavior
-
-No backend contract changes are needed.
-
-### Shared contract boundary
-
-`@mdcms/shared` owns:
-
-- typed `MdxPropHint` definitions
-- runtime validation of `catalog.components[*].propHints`
-- pure override mapping from `extractedProps + propHints` into explicit
-  field-control metadata
-
-This keeps widget semantics reusable across Studio and future local tooling.
-
-### Studio runtime boundary
-
-`@mdcms/studio` owns:
-
-- local validation of host-authored `propHints` during Studio config
-  preparation/loading
-- lazy `resolvePropsEditor(componentName)` handling
-- the custom-editor host lifecycle for the document route surface
-
-The Studio work should stay intentionally thin. It needs to prove the runtime
-can:
-
-- resolve a custom editor asynchronously
-- mount it with `value`, `onChange`, and `readOnly`
-- show the required state surfaces when the editor is missing, fails, or is not
-  editable
-
-It should not implement the full `MdxComponent` node-view props panel from
-`CMS-74`.
-
-### Scope split against CMS-74
-
-Keep out of scope:
-
-- TipTap `MdxComponent` node implementation
-- insertion UI and slash-command integration
-- inline node-view props drawers
-- MDX prop persistence into real component nodes in the editor document
-
-For `CMS-72`, it is sufficient to implement the reusable host/runtime surface
-and prove its lifecycle in the current document-route runtime shell.
-
-## Proposed Contract Shape
-
-### Widget hints
-
-Use a discriminated union for `propHints` entries:
-
-- `{ format: "url" }`
-- `{ widget: "color-picker" }`
-- `{ widget: "textarea" }`
-- `{ widget: "slider", min, max, step? }`
-- `{ widget: "image" }`
-- `{ widget: "select", options }`
-- `{ widget: "hidden" }`
-- `{ widget: "json" }`
-
-Validation rules:
-
-- `format` cannot be combined with `widget`
-- `color-picker`, `textarea`, and `image` only target extracted `string` props
-- `slider` only targets extracted `number` props and requires valid numeric
-  bounds
-- `select` requires a non-empty options list whose values match the target
-  scalar prop kind
-- `hidden` can suppress any extracted prop
-- `json` stays limited to JSON-serializable props and never enables function or
-  ref-like shapes
-
-### Shared auto-form output
-
-Extend the shared auto-form field union to cover:
-
-- `color-picker`
-- `textarea`
-- `slider`
-- `image`
-- `select`
-- `json`
-
-`hidden` should produce no field.
-
-The mapper should accept both `extractedProps` and `propHints`, validate the
-hint against the extracted prop, and then either:
-
-- emit the override control
-- fall back to the default control
-- omit the field for `hidden`
-
-### Custom editor lifecycle
-
-Change the host capability from synchronous resolution to async resolution:
-
-- `resolvePropsEditor(name): Promise<unknown | null>`
-
-The runtime host model should expose these states:
-
-- `loading`
-- `ready`
-- `empty`
-- `error`
-- `forbidden`
-
-`ready` mounts the resolved editor with:
-
-- `value`
-- `onChange`
-- `readOnly`
-
-## Testing Strategy
-
-Use TDD in this order:
-
-1. spec delta
-2. shared contract validation tests
-3. shared override-mapping tests
-4. Studio loader/runtime tests for async editor resolution
-5. runtime rendering tests for lifecycle states and `onChange`
-
-## Risks and Constraints
-
-- The spec currently names the `image` widget but does not define a richer media
-  payload shape. Keep `image` string-backed for this slice so the implementation
-  stays compatible with current specs and does not pull Post-MVP media contracts
-  into MVP editor work.
-- The current document route is still a mock runtime shell. The custom-editor
-  lifecycle should be implemented as a reusable runtime surface that can later
-  plug into `CMS-74`, not as one-off page-only logic.
-- `docs/plans/` is local-only in this repo, so planning artifacts must remain
-  untracked.

-# CMS-71 and CMS-72 Widget Hints and Custom Editors Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Implement the shared widget-hint override contract and the Studio custom props editor lifecycle so local MDX component metadata can drive validated auto-form overrides and lazily resolved custom editors with deterministic UI states.
-
-**Architecture:** Update `SPEC-007` first so the product contract explicitly defines typed `propHints`, precedence, validation rules, async custom-editor resolution, and lifecycle states. Then extend `@mdcms/shared` to type and validate widget hints and map them into explicit field controls. Finally, update `@mdcms/studio` to treat props editor resolution as an async lifecycle, render the required state surfaces on the document route, and prove `value` / `onChange` behavior with targeted runtime tests without pulling in full `CMS-74` node-view work.
-
-**Tech Stack:** Bun, Nx, TypeScript, node:test, Zod, React, Markdown specs/READMEs
-
----
-
-### Task 1: Apply the Owning Spec Delta
-
-**Files:**
-
-- Modify: `docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
-
-**Step 1: Update the spec before code**
-
-Add the approved contract language for:
-
-- typed `MdxPropHint`
-- `propHints` validation rules
-- precedence between `propsEditor`, widget overrides, and default controls
-- async `resolvePropsEditor(...)`
-- custom props editor lifecycle states
-- `value`, `onChange`, and `readOnly`
-
-**Step 2: Verify the spec wording**
-
-Run: `rg -n "MdxPropHint|resolvePropsEditor|loading|empty|error|forbidden|Widget-hint precedence" docs/specs/SPEC-007-editor-mdx-and-collaboration.md`
-
-Expected: all required lifecycle and precedence concepts are present in the owning spec.
-
-### Task 2: Add Shared Widget Hint Types and Validators
-
-**Files:**
-
-- Modify: `packages/shared/src/lib/contracts/extensibility.ts`
-- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
-- Modify: `packages/shared/README.md`
-
-**Step 1: Write the failing contract tests**
-
-Add coverage for:
-
-- accepted `propHints` shapes for all 7 widgets plus `{ format: "url" }`
-- rejected mixed `{ format, widget }` shapes
-- rejected invalid slider config
-- rejected empty `select.options`
-- rejected invalid option value types
-
-**Step 2: Run the contract test to verify it fails**
-
-Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
-
-Expected: FAIL because `propHints` is still opaque.
-
-**Step 3: Implement the shared contract**
-
-Add:
-
-- `MdxSelectOptionValue`
-- `MdxSelectOption`
-- `MdxPropHint`
-- typed `propHints?: Record<string, MdxPropHint>`
-- strict Zod validation for `catalog.components[*].propHints`
-
-Update the README with the supported widget-hint contract and precedence notes.
-
-**Step 4: Re-run the contract test**
-
-Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts`
-
-Expected: PASS
-
-### Task 3: Extend the Shared Auto-Form Mapper for Overrides
-
-**Files:**
-
-- Modify: `packages/shared/src/lib/mdx/auto-form.ts`
-- Modify: `packages/shared/src/lib/mdx/auto-form.test.ts`
-- Modify: `packages/shared/README.md`
-
-**Step 1: Write the failing mapper tests**
-
-Cover:
-
-- default mapping still works unchanged when `propHints` is missing
-- each widget override emits the expected control
-- `hidden` omits the field
-- valid widget overrides take precedence over default mapping
-- invalid or incompatible hints throw deterministic validation errors
-- JSON widget emits a JSON field instead of being skipped
-
-**Step 2: Run the mapper test to verify it fails**
-
-Run: `bun test packages/shared/src/lib/mdx/auto-form.test.ts`
-
-Expected: FAIL because the helper does not accept or honor widget hints.
-
-**Step 3: Implement the override mapper**
-
-Update the public field union and mapping helper to accept:
-
-- `extractedProps`
-- `propHints`
-
-Validate per-prop hint compatibility and emit explicit controls for:
-
-- `color-picker`
-- `textarea`
-- `slider`
-- `image`
-- `select`
-- `json`
-
-Keep `hidden` as omission.
-
-**Step 4: Re-run shared MDX tests**
-
-Run: `bun test packages/shared/src/lib/mdx/auto-form.test.ts packages/shared/src/lib/contracts/extensibility.test.ts packages/shared/src/lib/mdx/extracted-props.test.ts`
-
-Expected: PASS
-
-### Task 4: Validate Host Authored Hints During Studio Config Preparation
-
-**Files:**
-
-- Modify: `packages/studio/src/lib/studio.ts`
-- Modify: `packages/studio/src/lib/studio.test.ts`
-
-**Step 1: Write the failing preparation tests**
-
-Cover:
-
-- valid `propHints` survive prepared config
-- invalid `propHints` fail during config preparation with deterministic errors
-- extracted props and prepared metadata still include valid hints
-
-**Step 2: Run the preparation test to verify it fails**
-
-Run: `bun test packages/studio/src/lib/studio.test.ts`
-
-Expected: FAIL because Studio preparation does not validate hint semantics yet.
-
-**Step 3: Implement validation**
-
-Reuse the shared validator path so local Studio preparation rejects invalid host
-config before the runtime receives it.
-
-**Step 4: Re-run the preparation test**
-
-Run: `bun test packages/studio/src/lib/studio.test.ts`
-
-Expected: PASS
-
-### Task 5: Implement Async Custom Props Editor Resolution

-- Modify: `packages/studio/src/lib/studio-loader.ts`
-- Modify: `packages/studio/src/lib/studio-loader.test.ts`
-
-**Step 1: Write the failing loader/runtime contract tests**
-
-Cover:
-
-- `resolvePropsEditor` must be async
-- loaded local props editors are exposed as async resolver results
-- `null` is returned when no editor exists
-
-**Step 2: Run the relevant tests to verify failure**
-
-Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts packages/studio/src/lib/studio-loader.test.ts`
-
-Expected: FAIL because the resolver is currently synchronous.
-
-**Step 3: Implement async resolution**
-
-Update the shared contract and Studio loader to expose:
-
-- `resolvePropsEditor(name): Promise<unknown | null>`
-
-Preserve local loader behavior and host-bridge composition.
-
-**Step 4: Re-run the loader/runtime contract tests**
-
-Run: `bun test packages/shared/src/lib/contracts/extensibility.test.ts packages/studio/src/lib/studio-loader.test.ts`
-
-Expected: PASS

-- Create: `packages/studio/src/lib/mdx-props-editor-host.test.tsx`
-- Modify: `packages/studio/README.md`
-
-**Step 1: Write the failing lifecycle tests**
-
-Cover:
-
-- `loading` while async editor resolution is pending
-- `ready` when an editor resolves and receives `value`, `onChange`, `readOnly`
-- `empty` when resolver returns `null` and no auto-form fields exist
-- `error` when resolver rejects or render throws
-- `forbidden` when read-only mode blocks mutation
-- fallback to auto-form when no executable editor exists but generated controls do
-
-**Step 2: Run the lifecycle tests to verify failure**
-
-Run: `bun test packages/studio/src/lib/remote-studio-app.test.ts`
-
-Expected: FAIL because the runtime currently only exposes diagnostics text and has no lifecycle host.
-
-**Step 3: Implement the host component**
-
-Build a small reusable host that:
-
-- resolves editors lazily
-- manages lifecycle state
-- passes `value`, `onChange`, and `readOnly`
-- renders fallback auto-form metadata when appropriate
-
-Use the current document-route runtime surface as the proof integration point.
-
-**Step 4: Re-run the Studio runtime tests**

-# CMS-73 TipTap Baseline and Nested MDX Content Design
-
-> Local-only planning note. This file is not canonical product documentation and should remain uncommitted.
-
-## Summary
-
-Implement `CMS-73` as a real editor-core upgrade in `@mdcms/studio` that:
-
-- absorbs the missing TipTap editor baseline currently expected from earlier
-  roadmap slices
-- keeps the current document-route UI shell and editor-panel layout intact
-- introduces a generic `MdxComponent` TipTap node for wrapper and void MDX
-  components
-- enables nested rich-text editing for wrapper component `children` inside the
-  same editor document and autosave path
-- proves nested MDX round-tripping through targeted serialization and editor
-  tests
-
-## Spec Delta Summary
-
-No new spec text is required before implementation.
-
-The owning contract is already present in
-`docs/specs/SPEC-007-editor-mdx-and-collaboration.md`:
-
-- Markdown/MDX content is edited through TipTap.
-- MDX components are modeled as a single generic `MdxComponent` node.
-- Wrapper components expose a `block*` content hole for nested child content.
-- Nested child content is edited inline within the component block.
-- Serialization recursively renders wrapper children back into MDX.
-
-This task is therefore an implementation catch-up to an existing spec-owned
-contract, not a new product-surface change.
-
-## Current Gap
-
-The current repo already has:
-
-- a reusable markdown pipeline in
-  `packages/studio/src/lib/markdown-pipeline.ts`
-- local MDX catalog transport and extracted-prop metadata in
-  `@mdcms/shared` and `@mdcms/studio`
-- a runtime document route shell with save-state scaffolding and sidebars
-
-What is still missing:
-
-- a real `@tiptap/react` editor surface on the document route
-- MDX-aware TipTap extensions for parsing/rendering component nodes
-- a generic `MdxComponent` node implementation
-- inline wrapper-node content editing
-- round-trip tests for nested wrapper content
-
-The current
-`packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.tsx`
-remains a mock toolbar plus textarea, which is below the baseline already
-described by `SPEC-007`.
-
-## Approved Direction
-
-### Keep the current document UI
-
-Retain the current editor-page shell:
-
-- header
-- locale tabs
-- publish dialog
-- right sidebar
-- overall editor panel footprint
-
-This task upgrades behavior and editor internals, not the surrounding document
-page layout.
-
-### Absorb the missing baseline into CMS-73
-
-Treat the missing “real TipTap editor” work as part of `CMS-73` so the task can
-actually satisfy its own nested-content acceptance criteria and produce a
-usable dependency for `CMS-74`.
-
-This avoids:
-
-- building throwaway adapter code on top of the mock textarea
-- splitting foundational editor work across another unplanned slice
-- forcing `CMS-74` to redo baseline editor integration before it can add node
-  views and insertion UX
-
-## Architecture
-
-### Package ownership
-
-`@mdcms/shared` continues to own:
-
-- the MDX catalog contract
-- extracted prop metadata
-- the `children: { type: "rich-text" }` signal used to distinguish wrapper
-  components
-
-`@mdcms/studio` owns:
-
-- TipTap editor instantiation
-- MDX parsing and rendering integration
-- the generic `MdxComponent` extension
-- wrapper node-view rendering and nested editing
-- document-route editor UI wiring
-
-No backend or SDK contract changes are needed for this task because the editor
-still persists a single markdown/MDX body string.
-
-### Editor document model
-
-Use one top-level TipTap document as the only local editor state.
-
-- normal markdown blocks live directly in that document
-- wrapper MDX components become `MdxComponent` nodes with nested `content`
-- void MDX components become self-closing `MdxComponent` nodes with no child
-  content
-
-Nested wrapper content must not be modeled as a separate draft state or a
-second disconnected editor document. The editable child region should be driven
-by the same ProseMirror tree so page-level change handling and serialization
-remain whole-document operations.
-
-### Generic `MdxComponent` node
-
-Introduce a single editor node type that carries:
-
-- `componentName`
-- `props`
-- wrapper-vs-void semantics derived from the local MDX catalog
-
-Behavior:
-
-- if `extractedProps.children?.type === "rich-text"`, treat the component as a
-  wrapper and allow `block*` child content
-- otherwise treat it as void and serialize it as self-closing MDX
-
-This keeps the editor schema stable as the host app adds or removes registered
-components.
-
-### Markdown/MDX pipeline
-
-Extend the existing markdown pipeline rather than replacing it.
-
-- keep `parseMarkdownToDocument(...)`
-- keep `serializeDocumentToMarkdown(...)`
-- keep `roundTripMarkdown(...)`
-
-Add MDX-component-aware extensions so the pipeline can:
-
-- parse MDX component syntax into `MdxComponent` nodes
-- preserve JSON props in node attrs
-- recursively serialize wrapper children back into markdown within opening and
-  closing tags
-
-The implementation should stay compatible with the current spec direction of a
-custom tokenizer plus custom TipTap extension. If the parser work exposes a
-clear limitation for nested MDX, the limitation should be documented in code
-comments for the later fallback evaluation path already named in `SPEC-007`.
-
-### Node-view UI
-
-Wrapper node views should remain minimal in `CMS-73`.
-
-They need:
-
-- visible wrapper chrome so editors can identify the component boundary
-- component name display
-- a nested editable content region using the TipTap node-view content hole
-
-They do not need in this slice:
-
-- full host-app live preview rendering
-- component insertion panel
-- slash-command integration
-- polished props panel selection syncing
-
-That work remains aligned with `CMS-74`.
-
-## Scope Boundaries
-
-### In scope
-
-- replace the mock textarea editor internals with a real TipTap React editor
-- keep the current route-level UI shell
-- add the generic `MdxComponent` editor extension
-- support wrapper child-content editing inside component nodes
-- keep nested content in the same local document state and `onChange` path
-- serialize wrapper children back to MDX
-- document foundational behavior at point of use
-
-### Out of scope
-
-- full component insertion UX
-- slash command / toolbar insertion flows
-- host-app live component preview inside node views
-- deep props-panel selection synchronization
-- collaboration transport / Yjs wiring
-
-`SPEC-007` mentions collaboration participation for nested content, but that
-same spec also defers collaboration transport post-MVP. For this slice, the
-practical equivalent is that nested content stays in the same local editor
-document and autosave pipeline so future collaboration can bind to the same
-document tree later.
-
-## Testing Strategy
-
-Use TDD in this order:
-
-1. markdown-pipeline tests for wrapper parse/serialize round trips
-2. focused `MdxComponent` extension tests for wrapper-vs-void behavior
-3. React editor tests for rendering the real TipTap surface and updating nested
-   wrapper content
-4. route-level integration checks that document save-state callbacks still fire
-   from editor changes
-
-Verification should specifically prove:
-
-- wrapper MDX parses into editor state without dropping children
-- nested markdown formatting inside wrapper children round-trips correctly
-- editing nested child content updates the parent document serialization
-- current document-page shell behavior still works with the upgraded editor
-
-## Risks and Constraints
-
-- The current document route is a runtime-shell scaffold, so the real editor
-  integration should be implemented as reusable `@mdcms/studio` infrastructure
-  rather than page-only glue.
-- The task intentionally stops short of full `CMS-74` preview and insertion
-  UX; otherwise the slice would sprawl beyond the nested-content foundation.
-- `docs/plans/` is local-only in this repo, so this design note must remain
-  uncommitted.

-**Step 3: Run the tests to verify failure**
-
-Run: `bun test packages/studio/src/lib/markdown-pipeline.test.ts packages/studio/src/lib/mdx-component-extension.test.ts`
-
-Expected: FAIL because the current markdown pipeline has no MDX-component extension or wrapper-child support.
-
-### Task 2: Implement the Generic `MdxComponent` Extension and MDX Parsing Helpers
-
-**Files:**
-
-- Create: `packages/studio/src/lib/mdx-component-extension.ts`
-- Modify: `packages/studio/src/lib/markdown-pipeline.ts`
-- Modify: `packages/studio/src/lib/package-boundaries.test.ts`
-
-**Step 1: Implement the extension**
-
-Add a reusable generic TipTap node extension that carries:

-- `componentName`
-- `props`
-- wrapper-vs-void handling
-
-Keep wrapper detection catalog-aware and driven by extracted `children` metadata.
-
-**Step 2: Extend the markdown pipeline**
-
-Update the pipeline helpers so they can accept the MDX catalog context needed to:
-
-- parse MDX component tokens into `MdxComponent` nodes
-- serialize wrapper children recursively back into MDX
-- preserve existing plain-markdown behavior for documents without MDX components
-
-**Step 3: Re-run the failing editor-core tests**

-- Create: `packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.test.tsx`
-
-**Step 1: Add failing component tests**
-
-Cover:
-
-- initial markdown loads into the editor
-- editor changes call `onChange` with serialized markdown/MDX
-- wrapper child edits flow through the same callback as top-level edits
-
-**Step 2: Run the component tests to verify failure**
-
-Run: `bun test packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.test.tsx`
-
-Expected: FAIL because the current component is still a mock textarea and does not mount TipTap.
-
-**Step 3: Implement the real editor surface**
-
-Replace the textarea internals with:
-
-- `@tiptap/react` editor setup
-- the existing toolbar chrome wired to actual editor commands where already practical

-
-Run: `bun test packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.test.tsx`
-
-Expected: FAIL because wrapper node views do not exist yet.
-
-**Step 3: Implement the node view**
-
-Build a minimal node view that:
-
-- shows the component name and wrapper boundary
-- uses the TipTap content hole for wrapper child editing
-- avoids full preview or insertion UX that belongs to `CMS-74`

-
-**Step 3: Implement the route wiring**
-
-Pass real content and catalog context into the upgraded editor component while:
-
-- preserving the current header, publish dialog, locale tabs, and sidebar layout
-- keeping save-state updates driven by editor changes
-- avoiding unrelated UI redesign
-
-**Step 4: Re-run the route-level checks**

-# CMS-74 MDX Component Editor Design
-
-Date: 2026-03-26
-Task: `CMS-74 - Implement MdxComponent node view insert/edit/serialize/live preview`
-
-## Notes
-
-- This design doc is intentionally local-only under `docs/plans/` per repo workflow.
-- The owning spec is [SPEC-007](../specs/SPEC-007-editor-mdx-and-collaboration.md).
-- No spec delta is required before implementation. The task is already fully specified in `SPEC-007`.
-
-## Spec Delta Summary
-
-1. No new spec text is needed.
-2. The affected behavior is the document editor's MDX component insertion, selection-bound prop editing, live preview, and MDX round-tripping.
-3. Acceptance criteria 1-7 rely on the existing `SPEC-007` sections for:
-   - generic `MdxComponent` node behavior
-   - void vs wrapper semantics
-   - local catalog-backed insertion
-   - custom-editor and auto-form prop editing
-   - inline preview through the host bridge
-   - lifecycle states: `loading`, `empty`, `error`, `forbidden`
-
-## Current State
-
-The repo already contains most of the substrate for `CMS-74`:
-
-- `packages/studio/src/lib/mdx-component-extension.ts`
-  - generic `mdxComponent` TipTap node
-  - MDX tokenizer/parser/renderer
-  - void vs wrapper serialization behavior
-- `packages/studio/src/lib/mdx-props-editor-host.tsx`
-  - custom props editor lifecycle
-  - auto-form fallback
-  - `loading`, `empty`, `error`, and `forbidden` states
-- `packages/studio/src/lib/studio-loader.ts`
-  - local MDX catalog preparation
-  - host bridge wiring
-  - async props editor resolution
-- `packages/studio/src/lib/runtime-ui/components/editor/mdx-component-node-view.tsx`
-  - baseline node chrome for wrapper and void components
-
-The main gap is editor integration:
-
-- the toolbar still marks component insertion as planned-only
-- there is no slash-command support
-- the props panel is catalog-driven instead of selection-driven
-- the node view does not yet render inline host-app preview
-- there is no shared insertion controller used by both entrypoints
-
-## Decision
-
-Implement one shared MDX component insertion and editing flow with two entrypoints:
-
-1. toolbar picker
-2. `/` slash command
-
-Both entrypoints must use the same catalog source, selection rules, insertion defaults, and permission gating.
-
-## Architecture
-
-### 1. Shared insertion controller
-
-Introduce editor-local MDX helpers that:
-
-- read the MDX component catalog from `StudioMountContext`
-- infer whether a catalog entry is `void` or `wrapper`
-- insert a generic `mdxComponent` node with:
-  - `componentName`
-  - `props`
-  - `isVoid`
-- create a stable default insertion outcome:
-  - void components insert as self-closing nodes with empty content
-  - wrapper components insert with an empty content hole and focus moves into the wrapper body
-
-This controller becomes the single insertion path for both toolbar and slash command entrypoints.
-
-### 2. Editor-owned MDX selection state
-
-`TipTapEditor` becomes the owner of:
-
-- current selected `mdxComponent` node
-- picker open/closed state
-- insertion mode (`toolbar` or `slash`)
-- read-only / forbidden behavior passed down to editing surfaces
-
-The props panel must bind to the selected node, not to an arbitrary catalog entry.
-
-### 3. Toolbar picker and slash command
-
-Add one picker UI component that can be opened from:
-
-- the toolbar `Insert Component` button
-- a slash-command extension when the user types `/`
-
-The picker must show:
-
-- component name
-- optional description
-- component kind badge: `Void` or `Wrapper`
-
-The picker state contract must cover:
-
-- `ready`: list available components
-- `empty`: no local components registered
-- `forbidden`: list visible but insertion disabled
-
-### 4. Selection-bound props editing
-
-Replace the current catalog proof-surface behavior with selection-bound editing:
-
-- selecting a component node reveals the props panel for that node
-- prop mutations update node attrs immediately
-- custom editor lifecycle remains owned by `MdxPropsEditorHost`
-- auto-form fallback still derives from `extractedProps` + `propHints`
-
-Lifecycle expectations:
-
-- `loading`: async custom editor pending
-- `ready`: custom editor resolved and mounted
-- `empty`: no editable props for this node
-- `error`: resolver rejects or render boundary fails
-- `forbidden`: session may inspect but not mutate
-
-### 5. Inline preview
-
-The node view must render the actual host-app component inside the editor canvas via `context.hostBridge.renderMdxPreview(...)`.
-
-Preview behavior:
-
-- preview rerenders when node props change
-- preview remains visible in read-only mode
-- missing host component resolution produces a deterministic fallback instead of silent blank output
-- preview mounting always cleans up on node change/unmount
-
-### 6. Serialization
-
-Keep the existing generic node and extend tests so the pipeline proves:
-
-- parse -> edit -> serialize for void components
-- parse -> edit -> serialize for wrapper components
-- prop edits preserve component structure
-- wrapper child content continues to serialize as nested markdown
-
-## UI Behavior
-
-### Insertion
-
-1. User opens insertion via toolbar or `/`.
-2. Shared picker lists components from `context.mdx.catalog.components`.
-3. User selects one component.
-4. Editor inserts the generic node with correct `isVoid`.
-5. The newly inserted node becomes selected.
-6. The sidebar props panel opens for that node.
-7. For wrapper components, focus may move into the nested body after insertion.
-
-### Editing
-
-- Clicking or selecting a component node activates the component panel.
-- Prop edits update node attrs immediately.
-- Preview rerenders from the same local document state.
-- Wrapper child content stays editable in the document flow through the existing content hole.
-
-### Read-only and forbidden
-
-- Preview remains visible.
-- Picker may remain discoverable, but insertion actions are disabled.
-- Prop editors mount in inspection mode where applicable, but `onChange` cannot mutate node attrs.
-
-## Testing Strategy
-
-### Unit and integration coverage
-
-- extend `mdx-component-extension` tests for round-trip edits
-- add editor command tests through `createDocumentEditor(...)`
-- add picker and selection helper tests
-- add node-view tests for preview and fallback states
-- add props-panel tests for selection-bound behavior
-
-### Verification target
-
-Task verification calls for node-view e2e tests. Within the current package test setup, the implementation should at minimum add editor integration tests that exercise insertion, selection, and serialization end-to-end through the TipTap editor API. If the existing runtime test surface can support a heavier React integration path without new infrastructure, add that as well.
-
-## Scope Boundaries
-
-In scope:
-
-- generic `mdxComponent` insertion flow
-- toolbar picker
-- slash command
-- selection-bound prop editing
-- inline preview
-- lifecycle states required by spec
-- round-trip serialization coverage
-- README / inline documentation updates
-
-Out of scope:
-
-- generalized editor command palette
-- unrelated slash actions
-- collaboration transport
-- backend API changes
-- broader media workflows beyond existing prop widget contracts

-# CMS-74 MDX Component Editor Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Implement shared toolbar and slash-command MDX component insertion, selection-bound props editing, inline host-app preview, and round-trip coverage for the generic `mdxComponent` editor node.
-
-**Architecture:** Keep the existing generic `mdxComponent` TipTap extension and layer editor-owned selection/insertion behavior on top of it. Both insertion entrypoints use one catalog-backed controller, while the sidebar and node view bind to the currently selected MDX component node and reuse the existing props-editor lifecycle and host-bridge preview contracts.
-
-**Tech Stack:** Bun, Nx, TypeScript, React 19, TipTap 3, node:test
-

-# CMS-85 SDK Read Client Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

-**Goal:** Implement a thin read-focused SDK client in `@mdcms/sdk` with `createClient`, `get`, and `list`, including deterministic routing and error parsing.
-
-**Architecture:** Build a small fetch-based client in `packages/sdk` that maps directly to the content API. Keep the implementation schema-agnostic for reads, centralize request construction and response parsing, and cover behavior with Bun `node:test` tests using fetch stubs instead of a live server.
-
-**Tech Stack:** TypeScript, Bun test runner (`node:test`), workspace package exports, shared API/error contract types from `@mdcms/shared`

-# CMS-85 SDK Spec Alignment Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Align the SDK spec with the agreed read-focused contract and capture the deferred schema-hash pinning decision for future write clients.
-
-**Architecture:** Update the owning SDK spec so it no longer claims runtime-fetched schema can create compile-time typing, define `resolve` as a read option rather than a separate method, and record schema-hash pinning as a proposed ADR instead of an implied runtime cache behavior.
-
-**Tech Stack:** Markdown documentation under `docs/specs/` and `docs/adrs/`
-
----
-
-### Task 1: Update the SDK spec
-
-**Files:**
-
-- Modify: `docs/specs/SPEC-008-cli-and-sdk.md`
-
-**Step 1:** Replace the misleading runtime typing language with a read-focused SDK contract.
-
-**Step 2:** Define `resolve` as an option on `get` and `list`, not as a standalone SDK method.
-
-**Step 3:** Clarify routing defaults and per-call overrides.
-
-**Step 4:** State that schema-aware writes and schema hash pinning are deferred.
-
-### Task 2: Record the deferred decision
-
-**Files:**
-
-- Create: `docs/adrs/ADR-006-schema-hash-pinning-for-write-clients.md`
-- Modify: `docs/adrs/README.md`
-
-**Step 1:** Create a proposed ADR describing the open schema-hash pinning question.
-
-**Step 2:** Document the preferred direction and rejected auto-refresh approach.
-
-**Step 3:** Update the ADR catalog to list the proposed ADR.
-
-### Task 3: Verify the doc delta
-
-**Files:**
-
-- Review: `docs/specs/SPEC-008-cli-and-sdk.md`
-- Review: `docs/adrs/ADR-006-schema-hash-pinning-for-write-clients.md`
-- Review: `docs/adrs/README.md`
-
-**Step 1:** Re-read the changed sections for spec/ADR consistency.
-
-**Step 2:** Run targeted validation on the touched docs.
-
-**Step 3:** Confirm local-only planning files remain unstaged.

-# Compose Dev Studio Runtime Watch Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Make `docker-compose.dev.yml` rebuild the Studio runtime bundle automatically when `packages/studio/src/**` changes, without restarting the stack.
-
-**Architecture:** Keep the existing startup-owned Studio runtime publication model on the server. Add a dedicated Studio runtime watch script that rebuilds the published runtime artifacts on source changes and run it alongside the existing Studio TypeScript watcher in `packages/studio` dev mode.
-
-**Tech Stack:** Bun, Nx inferred `dev` targets, Node/Bun filesystem watching, node:test, Prettier
-
----
-
-### Task 1: Spec And Watcher Contract
-
-**Files:**
-
-- Modify: `docs/specs/SPEC-011-local-development-and-operations.md`
-- Create: `docs/plans/2026-03-26-compose-dev-studio-runtime-watch.md`
-
-**Step 1:** Add the explicit `docker-compose.dev.yml` watcher contract to `SPEC-011`.
-
-**Step 2:** Keep the plan local-only and out of the commit.
-
-### Task 2: Regression Test
-
-**Files:**
-
-- Create: `packages/studio/src/lib/dev-runtime-watch.test.ts`
-- Modify: `packages/studio/package.json`
-
-**Step 1:** Write a failing test that asserts the Studio `dev` script runs both the existing TypeScript watch and the new runtime artifact watcher.
-
-**Step 2:** Run only that test and confirm it fails because the current script only runs `tsc --watch`.
-
-### Task 3: Runtime Watcher
-
-**Files:**
-
-- Create: `packages/studio/src/lib/dev-runtime-watch.ts`
-- Modify: `packages/studio/package.json`
-
-**Step 1:** Implement a small Bun/Node watcher that watches `packages/studio/src/**`, debounces rapid changes, and reruns `buildStudioRuntimeArtifacts()`.
-
-**Step 2:** Keep the watcher log output actionable and non-spammy.
-
-**Step 3:** Update the Studio `dev` script to run both the TypeScript watch and the runtime watcher in one long-lived process.
-
-### Task 4: Documentation And Verification
-
-**Files:**
-
-- Modify: `apps/studio-example/README.md`
-
-**Step 1:** Update the local-dev docs so the watcher behavior matches the spec.
-
-**Step 2:** Run the focused watcher test.
-
-**Step 3:** Run `bun run format:check` and `bun run check`.

-# Studio Example MDX Demo Components Design
-
-Date: 2026-03-26
-Scope: register example local MDX components in `apps/studio-example` for Studio editor testing
-
-## Notes
-
-- This design doc is intentionally local-only under `docs/plans/` per repo workflow.
-- The owning spec is [SPEC-007](../specs/SPEC-007-editor-mdx-and-collaboration.md).
-- No spec delta is required. This work stays inside the existing local MDX component registration and prepared-catalog contract.
-
-## Spec Delta Summary
-
-1. No new spec text is needed.
-2. The affected behavior is the demo host app's local MDX component registration and how the embedded Studio route receives that prepared config.
-3. Acceptance depends on the existing `SPEC-007` sections covering:
-   - `config.components` as the source of truth
-   - host-local `load` and `loadPropsEditor` callbacks
-   - node-side prop extraction through `prepareStudioConfig(...)`
-   - local runtime preview and custom props editor resolution keyed by component name
-
-## Current State
-
-`apps/studio-example` currently exposes Studio through:
-
-- [apps/studio-example/app/admin/[[...path]]/page.tsx](../../apps/studio-example/app/admin/[[...path]]/page.tsx)
-- [apps/studio-example/app/admin/admin-studio-client.tsx](../../apps/studio-example/app/admin/admin-studio-client.tsx)
-
-The app's [mdcms.config.ts](../../apps/studio-example/mdcms.config.ts) currently defines only content types and environment metadata. It does not register any local MDX components.
-
-The admin route currently passes `createStudioEmbedConfig(config)` into `Studio`. That helper intentionally strips local MDX component registrations and loader callbacks, so simply adding components to `mdcms.config.ts` would not make them available to the current sample admin surface.
-
-The `/demo/content` routes intentionally render raw API payloads and raw body text. They are not part of this change.
-
-## Decision
-
-Implement a realistic host-app MDX demo surface for editor testing by:
-
-1. registering three example components in `apps/studio-example/mdcms.config.ts`
-2. adding the component modules and one custom props editor inside the sample app
-3. switching the admin route from embed-only config to `prepareStudioConfig(...)`
-
-The demo renderer remains raw-content only. This task is about validating Studio/editor integration, not front-end page rendering.
-
-## Approved Component Set
-
-### Chart
-
-- self-closing component
-- exercises void insertion
-- exercises auto-form editing
-- props:
-  - `data: number[]`
-  - `type: "bar" | "line" | "pie"`
-  - `title?: string`
-  - `color?: string`
-
-### Callout
-
-- wrapper component
-- exercises nested rich-text editing inside the editor canvas
-- props:
-  - `tone: "info" | "warning" | "success"`
-  - `title?: string`
-  - `children`
-
-### PricingTable
-
-- self-closing component
-- exercises custom props editor loading
-- props:
-  - `title?: string`
-  - `tiers: Array<{ name: string; price: string; description?: string }>`
-- edited through `PricingTable.editor.tsx` instead of auto-generated controls
-
-## Architecture
-
-### 1. Config-owned registration
-
-The sample host app continues to use `mdcms.config.ts` as the source of truth. The new `components` array will register:
-
-- `name`
-- `importPath`
-- `description`
-- `load`
-- `propHints` where useful
-- `propsEditor` and `loadPropsEditor` for `PricingTable`
-
-Because `apps/studio-example` does not currently define an `@/` path alias, the sample registrations should use plain relative import paths rather than introducing unrelated alias infrastructure.
-
-### 2. Prepared config on the admin route
-
-The admin route will prepare the authored config on the server with `prepareStudioConfig(...)` before passing it into the client `Studio` mount.
-
-This is the key integration change. It ensures the embedded Studio runtime receives:
-
-- serializable extracted prop metadata
-- catalog metadata for insertion and props-panel display
-- executable local preview loaders and custom-editor loaders through the config-owned runtime path
-
-The route must fail closed if preparation fails, rather than silently launching Studio without the registered components.
-
-### 3. No document-renderer changes
-
-The raw `/demo/content` pages stay untouched. They intentionally display API payloads and the stored document body text. They do not need to render MDX components for this testing slice.
-
-## UI and Data Flow
-
-1. The host app registers `Chart`, `Callout`, and `PricingTable` in `mdcms.config.ts`.
-2. The admin route calls `prepareStudioConfig(config, { cwd, tsconfigPath? })`.
-3. `prepareStudioConfig(...)` resolves component source files, extracts supported props, and preserves valid `propHints`.
-4. The prepared config is passed to `Studio`.
-5. Studio derives the local MDX catalog and host bridge from the prepared config.
-6. Editors can insert the example components through the CMS-74 toolbar and slash-command entrypoints.
-7. The props panel and preview path behave according to each component kind:
-   - `Chart` -> auto-form + preview
-   - `Callout` -> wrapper content + preview, no props-panel editing for `children`
-   - `PricingTable` -> custom props editor + preview
-
-## Error Handling
-
-- Invalid component import paths fail the admin route during preparation.
-- Invalid prop hints fail preparation instead of being ignored in the browser.
-- Missing custom props editor resolution continues to fall back to auto-form behavior where the Studio runtime already supports it.
-- Components with no editable extracted props continue to use the existing empty/custom panel states. No demo-only fallback logic is added.
-
-## Testing Strategy
-
-Add the narrowest tests that prove the sample host registration is wired correctly:
-
-- config-level coverage for the registered component names and loaders
-- admin-route coverage for using prepared config rather than stripped embed-only config
-- keep broader editor behavior coverage in `@mdcms/studio`, which already owns those contracts
-
-Verification should include:
-
-- focused tests added for the sample app integration
-- `bun nx build studio-example`
-- `bun nx typecheck studio-example`
-- workspace-required `bun run format:check`
-- workspace-required `bun run check`
-
-## Documentation
-
-Update [apps/studio-example/README.md](../../apps/studio-example/README.md) to explain that:
-
-- the sample app now registers local MDX components for Studio testing
-- the admin route uses prepared config so local catalog metadata reaches Studio
-- the `/demo/content` routes remain raw-content inspection surfaces
-
-## Scope Boundaries
-
-In scope:
-
-- demo-host MDX component files
-- config registration for three example components
-- one example custom props editor
-- admin route wiring to `prepareStudioConfig(...)`
-- sample-app README updates
-
-Out of scope:
-
-- rendering MDX on `/demo/content`
-- backend API changes
-- new path-alias infrastructure
-- changes to the core Studio MDX component contract

-# Studio Example MDX Demo Components Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Register `Chart`, `Callout`, and `PricingTable` in `apps/studio-example` so the sample admin Studio route can exercise local MDX insertion, preview, auto-form editing, wrapper editing, and custom props editor loading through the real prepared-config path.
-
-**Architecture:** Keep `apps/studio-example/mdcms.config.ts` as the source of truth for local MDX component registration. Add the example component modules inside the sample app, prepare the full config on the admin server route with `prepareStudioConfig(...)`, and document that the raw `/demo/content` pages remain renderer-free inspection surfaces.
-
-**Tech Stack:** Bun, Nx, TypeScript, React 19, Next.js 15, node:test, react-dom/server
-
----
-
-### Task 1: Add demo-host MDX component registrations and component modules
-
-**Files:**
-
-- Create: `apps/studio-example/components/mdx/Chart.tsx`
-- Create: `apps/studio-example/components/mdx/Callout.tsx`
-- Create: `apps/studio-example/components/mdx/PricingTable.tsx`
-- Create: `apps/studio-example/components/mdx/PricingTable.editor.tsx`
-- Modify: `apps/studio-example/mdcms.config.ts`
-- Test: `apps/studio-example/mdcms.config.test.ts`
-
-**Step 1: Write the failing test**
-
-Add a config test that imports `apps/studio-example/mdcms.config.ts` and asserts:
-
-- `config.components` exists
-- registered component names are exactly `Chart`, `Callout`, and `PricingTable`
-- `PricingTable` includes `propsEditor` and `loadPropsEditor`
-- `Chart` includes a `color` prop hint suitable for the auto-form demo
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test apps/studio-example/mdcms.config.test.ts`
-Expected: FAIL because the test file and component registrations do not exist yet.
-
-**Step 3: Write minimal implementation**
-
-Implement:
-
-- lightweight presentational sample components
-- a simple `PricingTable` custom editor using `PropsEditorComponent`
-- `mdcms.config.ts` component registrations with relative `importPath` values and local loader callbacks
-
-Example registration shape:
-
-```ts
-{
-  name: "Chart",
-  importPath: "./components/mdx/Chart",
-  description: "Render a small chart card in MDX content.",
-  load: () => import("./components/mdx/Chart").then((m) => m.Chart),
-  propHints: {
-    color: { widget: "color-picker" },
-  },
-}
-```
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test apps/studio-example/mdcms.config.test.ts`
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add apps/studio-example/components/mdx/Chart.tsx apps/studio-example/components/mdx/Callout.tsx apps/studio-example/components/mdx/PricingTable.tsx apps/studio-example/components/mdx/PricingTable.editor.tsx apps/studio-example/mdcms.config.ts apps/studio-example/mdcms.config.test.ts
-git commit -m "feat(studio-example): register mdx demo components"
-```
-
-### Task 2: Switch the sample admin route to prepared Studio config
-
-**Files:**
-
-- Modify: `apps/studio-example/app/admin/[[...path]]/page.tsx`
-- Modify: `apps/studio-example/app/admin/admin-studio-client.tsx`
-- Test: `apps/studio-example/app/admin/[[...path]]/page.test.tsx`
-
-**Step 1: Write the failing test**
-
-Add a narrow route test that proves the admin page no longer passes `createStudioEmbedConfig(config)` and instead provides a config object that still includes the registered MDX components.
-
-The test can import the default page function, render or inspect its returned element tree, and assert that the `config` prop handed to `AdminStudioClient` contains `components`.
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test 'apps/studio-example/app/admin/[[...path]]/page.test.tsx'`
-Expected: FAIL because the route still strips component registrations through `createStudioEmbedConfig(...)`.
-
-**Step 3: Write minimal implementation**
-
-Implement:
-
-- server-side `prepareStudioConfig(...)` usage in the admin page
-- `cwd` and `tsconfigPath` arguments that resolve correctly from `apps/studio-example`
-- any small prop-type adjustments needed in `AdminStudioClient`
-
-Example route shape:
-
-```tsx
-const preparedConfig = await prepareStudioConfig(config, {
-  cwd: process.cwd(),
-  tsconfigPath: join(process.cwd(), "apps/studio-example/tsconfig.json"),
-});
-
-return <AdminStudioClient config={preparedConfig} />;
-```
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test 'apps/studio-example/app/admin/[[...path]]/page.test.tsx'`
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add 'apps/studio-example/app/admin/[[...path]]/page.tsx' apps/studio-example/app/admin/admin-studio-client.tsx 'apps/studio-example/app/admin/[[...path]]/page.test.tsx'
-git commit -m "feat(studio-example): prepare local mdx config for studio"
-```
-
-### Task 3: Document the sample-app behavior
-
-**Files:**
-
-- Modify: `apps/studio-example/README.md`
-
-**Step 1: Write the failing test**
-
-Skip. This task is documentation-only.
-
-**Step 2: Run test to verify it fails**
-
-Skip. No behavior assertion is needed beyond the focused tests in Tasks 1-2.
-
-**Step 3: Write minimal implementation**
-
-Update the README to explain:
-
-- the sample app now registers `Chart`, `Callout`, and `PricingTable`
-- the admin route uses prepared config so Studio receives local MDX metadata
-- the `/demo/content` pages still show raw content and do not render MDX
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test apps/studio-example`
-Expected: PASS for the focused sample-app tests added earlier.
-
-**Step 5: Commit**
-
-```bash
-git add apps/studio-example/README.md
-git commit -m "docs(studio-example): document mdx demo components"
-```
-
-### Task 4: Final verification
-
-**Files:**
-
-- Verify only
-
-**Step 1: Run focused sample-app tests**
-
-Run: `bun test apps/studio-example`
-Expected: PASS
-
-**Step 2: Run demo-host build and typecheck**
-
-Run: `bun nx build studio-example && bun nx typecheck studio-example`
-Expected: PASS
-
-**Step 3: Run workspace baseline checks required by repo policy**
-
-Run: `bun run format:check && bun run check`
-Expected: PASS
-
-**Step 4: Confirm local-only files remain unstaged**
-
-Run: `git status --short`
-Expected: `docs/plans/`, `ROADMAP_TASKS.md`, `AGENTS.md`, and other local-only paths remain untracked and unstaged.

-# CMS-56 + CMS-133 Editor Publish Integration Design
-
-Date: 2026-03-27
-Tasks:
-
-- `CMS-56 - Wire Studio publish flow + version history panel + version diff view`
-- `CMS-133 - Integrate editor draft load/save flow with real content mutations`
-
-## Notes
-
-- This design doc is intentionally local-only under `docs/plans/` per repo workflow.
-- The owning specs are:
-  - [SPEC-003](../specs/SPEC-003-content-storage-versioning-and-migrations.md)
-  - [SPEC-004](../specs/SPEC-004-schema-system-and-sync.md)
-  - [SPEC-005](../specs/SPEC-005-auth-authorization-and-request-routing.md)
-  - [SPEC-007](../specs/SPEC-007-editor-mdx-and-collaboration.md)
-- No spec delta is required before implementation. The current spec set already defines the route behavior, auth mode, write guard, publish semantics, version-history contract, and version-detail reads needed for this slice.
-
-## Spec Delta Summary
-
-1. No spec text changes are required.
-2. The affected behavior is the Studio document editor route:
-   - draft document load
-   - draft update mutation
-   - publish flow with optional change summary
-   - version history display
-   - version diff between any two selected immutable snapshots
-3. Acceptance criteria depend on existing spec text for:
-   - `GET /api/v1/content/:documentId?draft=true`
-   - `PUT /api/v1/content/:documentId`
-   - `POST /api/v1/content/:documentId/publish`
-   - `GET /api/v1/content/:documentId/versions`
-   - `GET /api/v1/content/:documentId/versions/:version`
-   - schema-hash write enforcement on content writes
-   - session-authenticated CSRF bootstrap via `GET /api/v1/auth/session`
-
-## Current State
-
-The repo already contains the backend contracts required for this work:
-
-- `apps/server/src/lib/content-api/routes.ts`
-  - content read, update, publish, version summary, and version detail routes
-- `apps/server/src/lib/auth.ts`
-  - session route returning `csrfToken`
-  - CSRF protection for state-changing session requests
-  - RBAC checks for draft reads and publish operations
-- `packages/shared/src/lib/contracts/content-api.ts`
-  - shared version summary and version detail response shapes
-- `packages/studio/src/lib/document-shell.ts`
-  - draft document load helper with scoped headers and typed error states
-
-The gap is entirely on the Studio route side:
-
-- `packages/studio/src/lib/runtime-ui/pages/content-document-page.tsx`
-  - still reads from `mockDocuments`
-  - simulates publish locally
-  - has no real version history or diff state
-- `packages/studio/src/lib/runtime-ui/components/editor/editor-sidebar.tsx`
-  - still exposes mock field-editing controls that are not backed by schema-aware real mutations
-- there is no Studio-side helper for:
-  - CSRF bootstrap
-  - schema-hash derivation from local config
-  - real draft update mutation
-  - publish mutation
-  - version history fetch
-  - version diff construction
-
-## Decision
-
-Implement one dedicated Studio document-route data layer inside `packages/studio` and keep the route component mostly presentational.
-
-Do not add new backend endpoints.
-
-Do not turn this into a generic Studio-wide query framework.
-
-## Architecture
-
-### 1. Route-local data layer
-
-Add a typed Studio-side helper module responsible for:
-
-- bootstrapping CSRF for cookie-authenticated mutations through `GET /api/v1/auth/session`
-- loading the routed draft document
-- updating the draft document through `PUT /api/v1/content/:documentId`
-- publishing through `POST /api/v1/content/:documentId/publish`
-- loading version summaries and specific version snapshots
-- normalizing error handling into route-friendly states
-
-This keeps request details out of the page component and provides one reuse point for later `CMS-57` write gating.
-
-### 2. Local schema-hash derivation
-
-Draft writes must satisfy the `x-mdcms-schema-hash` contract from `SPEC-004`.
-
-The Studio route should derive the local schema hash from the full `MdcmsConfig` already accepted by `@mdcms/studio` when the host passes the authored config object instead of the shell-only embed config.
-
-The derivation should mirror the existing server-side demo-seed hashing inputs:
-
-- normalized raw config snapshot
-- resolved environment schema
-- active environment name
-
-If the route only receives shell-only config and cannot derive a trustworthy local schema hash, draft writes and publish must remain disabled with truthful copy. Reads still work.
-
-### 3. Truthful editor-route behavior
-
-The document route should stop pretending unfinished UI is live.
-
-That means:
-
-- keep real draft loading and body persistence in scope
-- keep real publish/history/diff in scope
-- remove or disable mock controls that imply unavailable schema-driven field editing
-- do not ship a fake locale switcher; locale-variant behavior remains owned by `CMS-63`
-- do not expand into schema-mismatch recovery UI; guarded write-mode belongs to `CMS-57`
-
-### 4. Publish and history model
-
-Publish remains explicit and versioned:
-
-- the publish dialog keeps the optional change-summary textarea
-- success refreshes the route document state and version history
-- version history lists:
-  - version
-  - `publishedBy`
-  - `publishedAt`
-  - `changeSummary`
-
-The history panel is read-only in this slice. Restore stays out of scope.
-
-### 5. Client-side diff model
-
-There is no spec-owned diff endpoint, so diff must be computed client-side from two fetched immutable version snapshots.
-
-The diff view should support any two selected versions, not only adjacent pairs.
-
-The comparison should cover:
-
-- path changes
-- frontmatter changes
-- body changes
-
-The implementation can stay simple and readable. It does not need a full word-level rich diff engine to satisfy the current spec.
-
-## UI Behavior
-
-### Document route lifecycle
-
-The route must render complete UI states for:
-
-- loading
-- ready
-- not found
-- forbidden
-- generic load error
-
-The page should continue to preserve route context (`type`, `documentId`) even when the content load fails.
-
-### Draft save behavior
-
-Draft updates are debounced from the editor route:
-
-- editing marks the route dirty immediately
-- a debounce triggers the real update mutation
-- save states are visible:
-  - `unsaved`
-  - `saving`
-  - `saved`
-  - `save failed`
-
-The page owns the canonical draft snapshot after each successful mutation so subsequent publish/history refreshes use real backend state.
-
-### Publish behavior
-
-- the Publish button opens the dialog
-- the dialog sends optional `changeSummary`
-- success closes the dialog, refreshes the current draft snapshot, and refreshes version history
-- forbidden or mutation failures surface inline route-level feedback
-
-### Version history and diff behavior
-
-- the route exposes a real version history panel
-- the panel supports:
-  - loading
-  - empty
-  - error
-  - populated
-- the user can select any two versions for comparison
-- selecting a version pair fetches the two immutable snapshots and renders the diff view
-
-## Testing Strategy
-
-### Studio helper tests
-
-Add focused tests for:
-
-- draft load
-- cookie-auth CSRF bootstrap
-- token-auth mutation path without CSRF bootstrap
-- schema-hash derivation
-- publish request payloads
-- version list/detail fetch behavior
-- typed error normalization
-
-### Route integration tests
-
-Add route-level tests covering:
-
-- loading -> ready flow
-- `FORBIDDEN`
-- `NOT_FOUND`
-- draft save success and failure
-- publish success and error
-- version history states
-- arbitrary-version diff selection
-- write-disabled state when schema-hash-capable config is unavailable
-
-### Existing regression coverage
-
-Keep existing tests green in:
-
-- `packages/studio`
-- touched shared helpers, if any
-- touched server packages, if any server change becomes necessary
-
-## Scope Boundaries
-
-In scope:
-
-- real draft document load for the routed editor
-- real draft body save
-- real publish flow
-- real version history panel
-- real version diff view
-- truthful editor-route control availability
-- package README updates for write-enabled config requirements
-
-Out of scope:
-
-- restore from version history
-- unpublish workflow unless needed to remove a misleading mock control
-- locale variant switching
-- schema mismatch banner and read-only recovery flow
-- schema browsing
-- environment-specific field badges
-- generalized Studio query/mutation framework
-- Post-MVP autosave durability behavior such as blur/disconnect flush and collaboration hooks

-# CMS-56 + CMS-133 Editor Publish Integration Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Replace the mock Studio document route with real draft load/save behavior and wire the publish, version-history, and version-diff flows against the existing content and auth contracts.
-
-**Architecture:** Keep the server contracts unchanged and add a document-route data layer inside `@mdcms/studio` that owns CSRF bootstrap, local schema-hash derivation, content mutations, version reads, and diff construction. The route page becomes a thin stateful container over that helper layer, while existing editor components continue to focus on markdown editing and MDX behavior.
-
-**Tech Stack:** Bun, Nx, TypeScript, React 19, node:test, Bun test, TipTap 3, shared MDCMS contracts
-
----
-
-### Task 1: Add document-route API helpers for load, save, publish, and versions
-
-**Files:**
-
-- Create: `packages/studio/src/lib/document-route-api.ts`
-- Test: `packages/studio/src/lib/document-route-api.test.ts`
-- Modify: `packages/studio/src/lib/document-shell.ts`
-- Modify: `packages/studio/src/lib/request-auth.ts`
-
-**Step 1: Write the failing test**
-
-Add tests that prove:
-
-- draft document reads send scoped headers and `draft=true`
-- cookie-authenticated mutations fetch CSRF from `GET /api/v1/auth/session`
-- token-authenticated mutations do not require CSRF bootstrap
-- publish sends optional `changeSummary`
-- version summary/detail helpers normalize success and failure states
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test packages/studio/src/lib/document-route-api.test.ts`
-Expected: FAIL because the helper file does not exist yet.
-
-**Step 3: Write minimal implementation**
-
-Implement one helper module that exposes:
-
-- draft load
-- session CSRF bootstrap
-- draft update
-- publish
-- version summary list
-- version detail fetch
-
-Reuse existing auth header logic instead of duplicating request-init behavior.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test packages/studio/src/lib/document-route-api.test.ts`
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add packages/studio/src/lib/document-route-api.ts packages/studio/src/lib/document-route-api.test.ts packages/studio/src/lib/document-shell.ts packages/studio/src/lib/request-auth.ts

-- Create: `packages/studio/src/lib/document-route-schema.ts`
-- Test: `packages/studio/src/lib/document-route-schema.test.ts`
-- Modify: `packages/studio/src/lib/studio.ts`
-- Modify: `packages/studio/src/index.ts`
-
-**Step 1: Write the failing test**
-
-Add tests that prove:
-
-- full authored Studio config can produce a deterministic local schema hash for the active environment
-- shell-only config cannot produce a write-capable schema hash result
-- the hash inputs remain stable for equivalent config data
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test packages/studio/src/lib/document-route-schema.test.ts`
-Expected: FAIL because the schema-hash helper does not exist yet.
-
-**Step 3: Write minimal implementation**
-
-Implement:
-
-- normalized raw config snapshot builder
-- environment schema serialization using shared config/schema helpers
-- deterministic SHA-256 hash generation
-- one route-facing capability result that says whether writes are allowed and why not
-
-Do not add new public server contracts.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test packages/studio/src/lib/document-route-schema.test.ts`
-Expected: PASS
-
-**Step 5: Commit**

-
-### Task 3: Add client-side version diff helpers
-
-**Files:**
-
-- Create: `packages/studio/src/lib/document-version-diff.ts`
-- Test: `packages/studio/src/lib/document-version-diff.test.ts`
-
-**Step 1: Write the failing test**
-
-Add tests that prove:
-
-- diff construction compares any two selected versions, not just adjacent ones
-- path changes are surfaced
-- frontmatter differences are surfaced
-- body line differences are surfaced deterministically
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test packages/studio/src/lib/document-version-diff.test.ts`
-Expected: FAIL because the diff helper does not exist yet.
-
-**Step 3: Write minimal implementation**
-
-Implement one small, readable diff helper that accepts two immutable version snapshots and returns structured sections for:
-
-- path
-- frontmatter
-- body
-
-Keep the implementation intentionally simple and dependency-light.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test packages/studio/src/lib/document-version-diff.test.ts`
-Expected: PASS
-
-**Step 5: Commit**
-
-```bash
-git add packages/studio/src/lib/document-version-diff.ts packages/studio/src/lib/document-version-diff.test.ts
-git commit -m "feat(studio): add document version diff helper"
-```
-
-### Task 4: Replace mock document-route state with real draft load and save behavior
-
-**Files:**
-
-- Modify: `packages/studio/src/lib/runtime-ui/pages/content-document-page.tsx`
-- Create: `packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx`
-- Modify: `packages/studio/src/lib/runtime-ui/components/editor/tiptap-editor.tsx`
-- Modify: `packages/studio/src/lib/remote-studio-app.test.ts`
-
-**Step 1: Write the failing test**
-
-Add tests that prove:
-
-- the page renders loading, ready, forbidden, not-found, and generic error states from real helper results
-- editor changes move through unsaved -> saving -> saved
-- failed save surfaces mutation feedback without pretending the draft persisted
-- write actions are disabled when local schema-hash capability is unavailable
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx packages/studio/src/lib/remote-studio-app.test.ts`
-Expected: FAIL because the route still reads from mock data.
-
-**Step 3: Write minimal implementation**
-
-Refactor the route so it:
-
-- loads the routed draft document through the new helper layer
-- owns debounced draft persistence
-- updates save-state labels from real request outcomes
-- keeps route context intact on failure
-
-Do not widen the editor component into a data-fetching surface.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx packages/studio/src/lib/remote-studio-app.test.ts`
-Expected: PASS

-### Task 5: Wire publish, version history, and arbitrary-version diff UI
-
-**Files:**

-- Modify: `packages/studio/src/lib/runtime-ui/components/ui/tabs.tsx`
-- Test: `packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx`
-
-**Step 1: Write the failing test**
-
-Add tests that prove:
-
-- publish opens the dialog, submits optional change summary, and refreshes route state on success
-- version history renders loading, empty, error, and populated states
-- the version panel shows version, `publishedBy`, `publishedAt`, and `changeSummary`
-- diff selection can compare any two chosen versions
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx`
-Expected: FAIL because publish/history/diff are still mock-only or absent.
-
-**Step 3: Write minimal implementation**
-
-Implement:
-
-- real publish dialog submit
-- route-level mutation feedback
-- real version history panel
-- arbitrary-version selection controls
-- diff rendering using the new helper
-
-Keep restore and unpublish out of scope unless one of them must be hidden to keep the page truthful.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx`
-Expected: PASS

-- Modify: `packages/studio/src/lib/runtime-ui/pages/content-document-page.tsx`
-- Modify: `packages/studio/README.md`
-
-**Step 1: Write the failing test**
-
-Add or update the narrowest UI assertion needed to prove:
-
-- mock-only field editors, fake locale switching, or other unfinished controls are hidden or truthfully disabled
-- route copy reflects the new write-capability requirement
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx packages/studio/src/lib/remote-studio-app.test.ts`
-Expected: FAIL because the page still exposes misleading controls.
-
-**Step 3: Write minimal implementation**
-
-Update the UI and docs so that:
-
-- unsupported controls are removed or explicitly disabled with truthful messaging
-- the README explains that write-enabled editor routes require full config data capable of local schema-hash derivation
-- concise inline comments explain any non-obvious capability gating
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx packages/studio/src/lib/remote-studio-app.test.ts`

-### Task 7: Final verification
-
-**Files:**
-
-- Verify only
-
-**Step 1: Run focused Studio tests**
-
-Run: `bun test packages/studio/src`
-Expected: PASS
-
-**Step 2: Run focused build and typecheck**
-
-Run: `bun nx build studio && bun nx typecheck studio`
-Expected: PASS
-
-**Step 3: Run repo-required baseline checks**
-
-Run: `bun run format:check && bun run check`
-Expected: PASS
-
-**Step 4: Confirm local-only paths remain unstaged**
-
-Run: `git status --short`
-Expected:
-
-- `docs/plans/` remains local-only and unstaged
-- `ROADMAP_TASKS.md`, `AGENTS.md`, and other local-only files remain unstaged
-
-**Step 5: Capture any residual risk**
-
-Record any remaining gaps only if verification reveals them. Do not silently broaden scope into `CMS-57`, `CMS-63`, or restore/unpublish follow-up work.

-# Studio Example SDK Content Demo Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Add a parallel SDK-backed content demo to the example app while preserving the existing raw content API inspection routes, and make the distinction obvious in navigation and page copy.
-
-**Architecture:** Keep `/demo/content*` as the direct-fetch raw API surface. Add `/demo/sdk-content*` routes that use `@mdcms/sdk` with the same configured project/environment scope and demo API key. Improve cross-linking and explicit "Data source" labels so developers can compare the raw API and SDK surfaces without ambiguity.
-
-**Tech Stack:** Next.js app routes, React server components, `@mdcms/sdk`, Bun workspace dependencies, node:test assertions for lightweight page tests.
-
----
-
-### Task 1: Capture the route split in the example app shell
-
-**Files:**
-
-- Modify: `apps/studio-example/app/page.tsx`
-- Modify: `apps/studio-example/README.md`
-
-**Step 1: Add the new demo route entry point**
-
-Update the host app landing page so it links to both `/demo/content` and `/demo/sdk-content`.
-
-**Step 2: Clarify route ownership in docs**
-
-Update the example app README route list and runbook text so raw API pages and SDK pages are both documented, with explicit notes about their data sources.
-
-### Task 2: Add focused tests for the new demo distinction
-
-**Files:**
-
-- Create: `apps/studio-example/app/demo/sdk-content/page.test.tsx`
-- Create: `apps/studio-example/app/demo/sdk-content/[documentId]/page.test.tsx`
-- Modify: `apps/studio-example/app/page.tsx`
-
-**Step 1: Write a failing list-page test**
-
-Add a lightweight page test that asserts the SDK list page renders an SDK-specific heading or data-source label and links back to the raw surface.
-
-**Step 2: Write a failing detail-page test**
-
-Add a lightweight page test that asserts the SDK detail page renders an SDK-specific heading or data-source label and links back to the SDK list and raw detail/list surfaces as appropriate.
-
-**Step 3: Run the focused tests to confirm failure**
-
-Run the new page tests directly with Bun.
-
-### Task 3: Implement the SDK-backed demo routes
-
-**Files:**
-
-- Create: `apps/studio-example/app/demo/sdk-content/page.tsx`
-- Create: `apps/studio-example/app/demo/sdk-content/[documentId]/page.tsx`
-- Create: `apps/studio-example/app/demo/sdk-content/sdk-demo-client.ts`
-- Modify: `apps/studio-example/package.json`
-
-**Step 1: Add the SDK dependency**
-
-Add `@mdcms/sdk` to the example app package so the demo routes can consume the published package boundary directly.
-
-**Step 2: Centralize SDK client creation**
-
-Create a small server-only helper that reads `mdcms.config.ts`, injects the optional `MDCMS_DEMO_API_KEY`, and returns `createClient(...)`.
-
-**Step 3: Implement the SDK list page**
-
-Render the same content summary shape as the raw page, but fetch through `client.list(...)`. Add explicit labeling that the page is using `@mdcms/sdk`.
-
-**Step 4: Implement the SDK detail page**
-
-Fetch by document ID through `client.get(...)`, render the same raw body/frontmatter presentation, and include explicit data-source labeling plus navigation between raw and SDK views.
-
-### Task 4: Tighten the raw pages and shared navigation copy
-
-**Files:**
-
-- Modify: `apps/studio-example/app/demo/content/page.tsx`
-- Modify: `apps/studio-example/app/demo/content/[documentId]/page.tsx`
-
-**Step 1: Add explicit raw-API labeling**
-
-Keep the raw routes as-is functionally, but make the page titles and copy explicitly say "Raw Content API".
-
-**Step 2: Cross-link the raw and SDK views**
-
-Add links on each raw page to the corresponding SDK surface so comparison is one click away.
-
-### Task 5: Verify and document
-
-**Files:**
-
-- Modify: `apps/studio-example/README.md`
-
-**Step 1: Update the runbook**
-
-Point the demo verification section at both surfaces and describe what each one demonstrates.
-
-**Step 2: Run focused verification**
-
-Run targeted `bun test` commands for the new page tests, then `bun run format:check`, then `bun run check`.
-
-**Step 3: Leave local-only planning files uncommitted**
-
-Do not stage anything under `docs/plans/`.

-# SDK Post-MVP Epic Design
-
-**Date:** 2026-03-31
-
-## Goal
-
-Capture the approved post-MVP SDK backlog split so Jira can reflect clear SDK ownership without expanding MVP scope.
-
-## Decisions
-
-- MVP SDK remains read-only.
-- Strong SDK type safety is desired, but it is post-MVP.
-- Full SDK mutations are also post-MVP.
-- Type safety should be schema-derived rather than based on user-authored types.
-
-## Epic Split
-
-### SDK Type System & Query Surface
-
-Owns schema-derived type generation and the typed read/query experience:
-
-- generated content type map from schema artifacts
-- typed `get` / `list`
-- typed filter and sort inputs
-- typed `resolve` path support
-- cursor pagination support in the SDK query surface
-- typed read docs, examples, and contract coverage
-
-### SDK Mutations & Write Safety
-
-Owns direct SDK write flows and the compatibility boundary around writes:
-
-- SDK write contract/spec work after schema-hash pinning is resolved
-- local schema-hash artifact flow for SDK write clients
-- create / update mutations
-- delete / restore mutations
-- publish / unpublish mutations
-- version history / restore helpers
-- deterministic mutation error taxonomy
-- write docs, examples, and compatibility coverage
-
-## Dependency Notes
-
-- `CMS-147` remains the architecture input for SDK write safety and should not be moved until the spike is complete.
-- `CMS-100` remains under `Search`.
-- `CMS-908` should move under `SDK Type System & Query Surface` because it is SDK query-surface work.
-- SDK write implementation tasks must depend on the post-`CMS-147` write contract/spec task.

-# Studio Schema Guard And Read-Only Browser Design
-
-Date: 2026-03-31
-
-## Goal
-
-Implement a combined Studio slice that:
-
-- blocks document writes when the local Studio schema hash does not match the synced server schema hash
-- lets privileged users run an explicit `Sync Schema` recovery action
-- replaces the placeholder `/admin/schema` surface with a live read-only schema browser
-
-This design intentionally combines the schema mismatch guard and read-only schema browsing work while excluding the broader Settings MVP cleanup.
-
-## Scope
-
-Included:
-
-- live schema fetch for the active `(project, environment)` target
-- local-versus-server schema hash comparison
-- guarded read-only editor mode while mismatch is unresolved
-- explicit privileged `Sync Schema` action backed by `PUT /api/v1/schema`
-- live read-only schema browser UI for `/admin/schema`
-- minimal Settings integration that reuses or points to the shared schema browser path
-
-Excluded:
-
-- broad Settings tab cleanup and truthful-control audit
-- new client-side auth/session contracts for role exposure
-- manual schema editing controls in Studio
-
-## Contract Basis
-
-The behavior is already specified by:
-
-- `docs/specs/SPEC-004-schema-system-and-sync.md`
-- `docs/specs/SPEC-005-auth-authorization-and-request-routing.md`
-- `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-
-The design relies on existing server behavior:
-
-- `GET /api/v1/schema` for read-only schema browsing
-- `PUT /api/v1/schema` for privileged explicit sync
-- content write rejection when `x-mdcms-schema-hash` is missing or mismatched
-
-## Architecture
-
-Add one Studio-side schema state path in `packages/studio/src/lib` that:
-
-1. fetches the current schema registry entries for the active target
-2. derives the local config snapshot and local schema hash from the existing Studio config capability path
-3. compares the local hash with the server hash
-4. exposes a `syncSchema()` action that forwards the local snapshot to `PUT /api/v1/schema`
-
-That state becomes the shared source for:
-
-- `/admin/schema` read-only schema browsing
-- document editor write gating and mismatch recovery
-
-The client should not gain a new role contract in this slice. Capability is derived from endpoint behavior:
-
-- `GET /schema` success means schema browsing is available
-- `PUT /schema` success means the current user can perform privileged sync
-- `403` on sync means the user remains in read-only recovery without the action
-
-## Components And Data Flow
-
-### Schema Adapter
-
-Create a Studio adapter beside the existing action and document adapters that wraps:
-
-- `GET /api/v1/schema`
-- `PUT /api/v1/schema`
-
-The adapter applies:
-
-- Studio auth mode (`cookie` or `token`)
-- target headers: `X-MDCMS-Project`, `X-MDCMS-Environment`
-- CSRF bootstrap for session-authenticated writes before `PUT /schema`
-
-### Shared Schema State
-
-Add a shared state module or hook that normalizes:
-
-- `loading`
-- `ready`
-- `empty`
-- `forbidden`
-- `error`
-
-and derives:
-
-- `localSchemaHash`
-- `serverSchemaHash`
-- `isMismatch`
-- `canSync`
-- `syncStatus`
-
-It should expose:
-
-- schema entries
-- reload
-- sync action
-- deterministic error metadata
-
-### Schema Browser UI
-
-Replace `/admin/schema` with a real read-only browser backed by live schema entries.
-
-The page should:
-
-- render content types, fields, localization, and validator metadata from `resolvedSchema`
-- never expose schema edit controls
-- show loading, empty, forbidden, and generic error states
-- surface the same mismatch banner and privileged recovery action when applicable
-
-### Document Editor Guard
-
-The document route should consume the shared schema state and enter guarded read-only mode when:
-
-- the local schema is unavailable, or
-- the local and server schema hashes do not match
-
-In guarded read-only mode:
-
-- the editor remains readable
-- draft save and publish actions are disabled
-- the page shows an explanatory banner
-- privileged users can run `Sync Schema`
-- non-privileged users see recovery guidance only
-
-## Error Handling
-
-### Loading
-
-Before schema state resolves, Studio should keep guarded write actions disabled rather than briefly enabling them.
-
-### Forbidden
-
-If `GET /api/v1/schema` returns `403`, the schema page shows a forbidden state. If a user can read content but cannot sync schema, the document page still stays read-only when mismatch is detected and omits the privileged action.
-
-### Sync Failure
-
-`PUT /api/v1/schema` failures should surface clearly:
-
-- `403`: sync is not permitted for this user
-- `409`: schema is incompatible and requires migration or another operator action
-- `400`: local payload/config cannot be synced as-is
-
-Write blocking remains active until the mismatch clears.
-
-### Recovery
-
-After a successful sync:
-
-- Studio reloads schema state
-- the mismatch banner clears
-- document write affordances re-enable without a full page reload
-
-## Verification
-
-Required verification should cover:
-
-- schema adapter tests for `GET /schema` and `PUT /schema`
-- schema state tests for loading, forbidden, mismatch, and sync transitions
-- schema page tests proving live read-only rendering with no edit controls
-- document page tests proving mismatch disables save and publish affordances
-- guarded-write API tests covering privileged sync and non-privileged rejection
-
-## Notes
-
-- `docs/plans` is local-only workspace documentation in this repository, so this design file is intentionally not part of the canonical committed product docs.
-- The later Settings cleanup work should stay separate. This slice should only make the minimal Settings changes needed to avoid duplicating schema UI logic.

-# Studio Schema Guard And Read-Only Browser Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Add a shared Studio schema state path that powers live read-only schema browsing and guarded write-blocking recovery when the local schema hash does not match the server schema hash.
-
-**Architecture:** Reuse the existing local schema capability logic in `@mdcms/studio` to derive the local config snapshot and hash, add a dedicated schema route adapter for `GET /api/v1/schema` and `PUT /api/v1/schema`, and feed that shared state into `/admin/schema`, Settings schema access, and the document route guard. Keep auth capability inference server-driven via endpoint responses instead of adding new role data to the client session contract.
-
-**Tech Stack:** Bun, React 19, TypeScript, `@mdcms/shared` contracts, existing Studio runtime adapters, Bun test, server schema/content APIs.
-
----
-
-### Task 1: Add Studio Schema Route Adapter
-
-**Files:**
-
-- Create: `packages/studio/src/lib/schema-route-api.ts`
-- Create: `packages/studio/src/lib/schema-route-api.test.ts`
-- Modify: `packages/studio/package.json`
-
-**Step 1: Write the failing adapter tests**
-
-Cover:
-
-- `GET /api/v1/schema` sends `X-MDCMS-Project` and `X-MDCMS-Environment`
-- cookie auth uses `credentials: "include"`
-- token auth sends `Authorization: Bearer ...`
-- `PUT /api/v1/schema` bootstraps CSRF for cookie auth, forwards the local payload, and surfaces `403` / `409` failures as runtime errors
-
-Use the existing test style from:
-
-- `packages/studio/src/lib/document-route-api.test.ts`
-- `packages/studio/src/lib/studio.test.ts`
-
-**Step 2: Run test to verify it fails**
-
-Run:
-
-```bash
-bun test packages/studio/src/lib/schema-route-api.test.ts
-```
-
-Expected:
-
-- FAIL because `schema-route-api.ts` does not exist yet
-
-**Step 3: Write minimal implementation**
-
-Implement a dedicated adapter that:
-
-- accepts `{ project, environment, serverUrl }`
-- exposes `listSchema()` and `syncSchema(payload)`
-- uses the existing `applyStudioAuthToRequestInit(...)`
-- uses `GET /api/v1/auth/session` to obtain `csrfToken` for session-authenticated sync when needed
-- validates and returns shared schema contract shapes from `@mdcms/shared`
-
-Do not export this adapter from the public package root unless a real external consumer requires it.
-
-**Step 4: Run test to verify it passes**
-
-Run:
-
-```bash
-bun test packages/studio/src/lib/schema-route-api.test.ts
-```
-
-Expected:
-
-- PASS
-
-**Step 5: Commit**
-
-```bash
-git add packages/studio/src/lib/schema-route-api.ts packages/studio/src/lib/schema-route-api.test.ts packages/studio/package.json
-git commit -m "feat(studio): add schema route adapter"
-```
-
-### Task 2: Extend Local Schema Capability Into Shared Schema State
-
-**Files:**
-
-- Modify: `packages/studio/src/lib/document-route-schema.ts`
-- Create: `packages/studio/src/lib/schema-state.ts`
-- Create: `packages/studio/src/lib/schema-state.test.ts`
-- Modify: `packages/studio/src/lib/studio-loader.ts`
-- Modify: `packages/shared/src/lib/contracts/extensibility.ts`
-- Modify: `packages/shared/src/lib/contracts/extensibility.test.ts`
-
-**Step 1: Write the failing state and contract tests**
-
-Cover:
-
-- local capability now exposes the full sync payload pieces needed by Studio: `rawConfigSnapshot`, `resolvedSchema`, and `schemaHash`
-- mount context still supports the existing document route write contract
-- shared schema state computes `isMismatch`, `canSync`, and deterministic `loading/ready/forbidden/error` states from adapter responses
-
-Use the existing fixtures in:
-
-- `packages/studio/src/lib/document-route-schema.test.ts`
-- `packages/studio/src/lib/studio-loader.test.ts`
-- `packages/shared/src/lib/contracts/extensibility.test.ts`
-
-**Step 2: Run test to verify it fails**
-
-Run:
-
-```bash
-bun test packages/studio/src/lib/document-route-schema.test.ts packages/studio/src/lib/schema-state.test.ts packages/studio/src/lib/studio-loader.test.ts packages/shared/src/lib/contracts/extensibility.test.ts
-```
-
-Expected:
-
-- FAIL because the richer capability and shared schema state do not exist yet
-
-**Step 3: Write minimal implementation**
-
-Update `resolveStudioDocumentRouteSchemaCapability(...)` so the write-enabled path includes:
-
-- `environment`
-- `rawConfigSnapshot`
-- `resolvedSchema`
-- `schemaHash`
-
-Add a new internal schema state module that:
-
-- fetches server schema entries
-- derives `serverSchemaHash` from the returned registry entries
-- compares against the local hash
-- exposes `syncSchema()` that uses the local sync payload
-
-If you must extend `StudioMountContext`, keep it narrow and internal-facing. Preserve compatibility with existing loader tests and runtime consumers.
-
-**Step 4: Run test to verify it passes**
-
-Run:
-
-```bash
-bun test packages/studio/src/lib/document-route-schema.test.ts packages/studio/src/lib/schema-state.test.ts packages/studio/src/lib/studio-loader.test.ts packages/shared/src/lib/contracts/extensibility.test.ts

-### Task 3: Replace Placeholder Schema Page With Live Read-Only Browser
-
-**Files:**
-
-- Modify: `packages/studio/src/lib/runtime-ui/app/admin/schema-page.tsx`
-- Create: `packages/studio/src/lib/runtime-ui/app/admin/schema-page.test.tsx`
-- Modify: `packages/studio/src/lib/remote-studio-app.tsx`
-- Modify: `packages/studio/src/lib/remote-studio-app.test.ts`
-
-**Step 1: Write the failing schema page tests**
-
-Cover:
-
-- loading, empty, forbidden, and generic error states
-- rendering of type name, directory, localized badge, field kind, required flag, and constraint metadata from live schema entries
-- no schema edit controls
-- mismatch banner and privileged `Sync Schema` action rendering when state says mismatch + `canSync`
-
-Reuse existing render patterns from:
-
-- `packages/studio/src/lib/remote-studio-app.test.ts`
-- `packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx`
-
-**Step 2: Run test to verify it fails**
-
-Run:
-
-```bash
-bun test packages/studio/src/lib/runtime-ui/app/admin/schema-page.test.tsx packages/studio/src/lib/remote-studio-app.test.ts
-```
-
-Expected:
-
-- FAIL because `/admin/schema` is still a static placeholder
-
-**Step 3: Write minimal implementation**
-
-Replace the current placeholder with a read-only browser component that consumes the shared schema state and renders:
-
-- top-level mismatch banner
-- optional sync action
-- grouped schema entries
-- field tables derived from `resolvedSchema.fields`
-
-Keep the UI truthful:
-
-- no builder copy
-- no drag-and-drop claims
-- no edit or mutation affordances
-
-**Step 4: Run test to verify it passes**
-
-Run:
-
-```bash
-bun test packages/studio/src/lib/runtime-ui/app/admin/schema-page.test.tsx packages/studio/src/lib/remote-studio-app.test.ts

-
-Expected:

-
-### Task 4: Wire Guarded Read-Only Editor Recovery
-
-**Files:**
-
-- Modify: `packages/studio/src/lib/runtime-ui/pages/content-document-page.tsx`
-- Modify: `packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx`
-- Modify: `packages/studio/src/lib/document-shell.ts`
-- Modify: `packages/studio/src/lib/document-route-api.ts`
-- Modify: `packages/studio/src/lib/document-route-api.test.ts`
-
-**Step 1: Write the failing document route tests**
-
-Cover:
-
-- mismatch state disables draft save and publish affordances
-- guarded banner renders the server-versus-local schema recovery state
-- privileged sync clears the mismatch path after successful reload
-- non-privileged users see read-only recovery text without the sync action
-- `SCHEMA_HASH_MISMATCH` and `SCHEMA_NOT_SYNCED` failures map into the guarded UI path rather than generic save errors
-
-**Step 2: Run test to verify it fails**
-
-Run:
-
-```bash
-bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx packages/studio/src/lib/document-route-api.test.ts
-```
-
-Expected:
-
-- FAIL because mismatch handling and recovery are not wired yet
-
-**Step 3: Write minimal implementation**
-
-Integrate the shared schema state into the existing document page state machine:
-
-- treat mismatch as guarded read-only
-- preserve readable content and version history
-- disable draft mutation and publish paths while guarded
-- surface sync recovery UI from the shared state
-
-Preserve the existing document route mount contract for save requests so the actual write path still sends `x-mdcms-schema-hash` when writes are allowed.
-
-**Step 4: Run test to verify it passes**
-
-Run:
-
-```bash
-bun test packages/studio/src/lib/runtime-ui/pages/content-document-page.test.tsx packages/studio/src/lib/document-route-api.test.ts

-
-### Task 5: Minimal Settings Integration And Documentation
-
-**Files:**
-
-- Modify: `packages/studio/src/lib/runtime-ui/app/admin/settings-page.tsx`
-- Modify: `packages/studio/README.md`
-
-**Step 1: Write the failing assertions**
-
-Add or extend tests so Settings does one of the following truthfully:
-
-- reuses the shared read-only schema browser content, or
-- links users to `/admin/schema` instead of maintaining a separate mock viewer
-
-Also add assertions for the updated README copy:
-
-- schema mismatch recovery is now live
-- `/admin/schema` is a live read-only browser
-
-**Step 2: Run test to verify it fails**
-
-Run:
-
-```bash
-bun test packages/studio/src/lib/remote-studio-app.test.ts packages/studio/src/lib/studio.test.ts
-```
-
-Expected:
-
-- FAIL until Settings and docs align with the live behavior
-
-**Step 3: Write minimal implementation**
-
-Keep this change narrow:
-
-- remove the duplicated mock schema viewer from Settings
-- replace it with shared schema access or a clear link to the real schema browser
-- update `packages/studio/README.md` at the point of use to describe the live schema browser and mismatch recovery workflow
-
-Do not clean up unrelated Settings tabs or post-MVP surfaces here.
-
-**Step 4: Run test to verify it passes**
-
-Run:
-
-```bash
-bun test packages/studio/src/lib/remote-studio-app.test.ts packages/studio/src/lib/studio.test.ts

-
-Expected:
-
-- PASS

-**Step 5: Commit**
-
-```bash
-git add packages/studio/src/lib/runtime-ui/app/admin/settings-page.tsx packages/studio/README.md
-git commit -m "docs(studio): document schema guard and browser"

-
-**Step 1: Run focused Studio and shared tests**
-
-```bash
-bun test packages/studio/src packages/shared/src/lib/contracts

-
-**Step 2: Run server schema/content tests that cover guarded-write compatibility**
-
-```bash

-# Studio Review Preview Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Add a private `apps/studio-review` Next.js app that renders MDCMS Studio against scenario-scoped mock API routes and a locally built Studio runtime so pull requests can review visual Studio changes without the full Compose stack.
-
-**Architecture:** Keep the real Studio package and production host app untouched. The review app owns its own `serverUrl` subtree (`/review-api/:scenario`) that serves a real bootstrap manifest plus runtime asset bytes using the existing `@mdcms/studio/build-runtime` helper, and serves deterministic mock API responses for capabilities, schema, and document endpoints through Next route handlers. The review admin route prepares a local Studio config with MDX component metadata and mounts the normal `<Studio />` component against those review-only endpoints.
-
-**Tech Stack:** Bun, Nx workspace apps, Next.js App Router, `@mdcms/studio`, `@mdcms/studio/build-runtime`, repo-local route handlers, node:test / Bun test, React server rendering tests.

-# CMS-131 Content Overview Design
-
-## Scope
-
-Finish `CMS-131` by completing the `/admin/content` live overview so it can:
-
-- render truthful per-type `total`, `published`, and `drafts` counts for callers
-  with `content:read`
-- persist the Studio light/dark theme across reloads and remounts
-- keep the existing real schema-driven cards, locale badges, and localized demo
-  content intact
-
-## Design
-
-### Overview counts
-
-The current page derives counts by calling `GET /api/v1/content` with
-`limit=1` and reading `pagination.total`. That means the route still receives a
-real `data` array with document payloads even though the overview only needs
-counts. It also means `total` and `draft`-derived metrics currently depend on
-`draft=true`, which requires `content:read:draft`.
-
-To separate metadata visibility from draft document access:
-
-- add a dedicated `GET /api/v1/content/overview` endpoint in the content API
-- keep required scope at `content:read`
-- return metadata-only rows per requested type with no document bodies or list
-  payloads
-- define `drafts` as non-deleted documents whose current head has no published
-  version
-
-### Theme persistence
-
-The Studio `ThemeProvider` currently stores the theme only in React state and
-reapplies the `dark` class on mount. It should own browser-local persistence
-through `localStorage` and derive the effective theme using:
-
-1. persisted Studio preference
-2. explicit `defaultTheme`
-3. system preference when `enableSystem` is enabled
-4. `light`
-

-- Preserve the existing `GET /api/v1/content?draft=true` permission model.
-- Do not commit files under `docs/plans/`; they are local workflow artifacts in

-# CMS-131 Content Overview Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Finish CMS-131 by adding a metadata-only content overview endpoint, wiring `/admin/content` to it, and persisting the Studio theme.
-
-**Architecture:** Extend the content API with a dedicated overview-count contract that exposes per-type metadata without document rows, then update the Studio overview loader to consume that contract while keeping list/detail permissions unchanged. Persist the Studio theme inside the existing runtime theme adapter with local browser storage and deterministic precedence.
-
-**Tech Stack:** Bun, Nx, TypeScript, React, Zod, custom server content API, GitHub CLI.
-
----
-
-### Task 1: Spec delta
-
-**Files:**
-
-- Modify: `docs/specs/SPEC-003-content-storage-versioning-and-migrations.md`
-- Modify: `docs/specs/SPEC-006-studio-runtime-and-ui.md`
-
-**Step 1: Write the spec delta**
-
-- Add `GET /api/v1/content/overview` as a metadata-only endpoint in `SPEC-003`
-- Update `/admin/content` count and theme persistence behavior in `SPEC-006`
-
-**Step 2: Verify wording against current code**
-
-Run: `rg -n "content/overview|theme persistence|/admin/content" docs/specs/SPEC-003-content-storage-versioning-and-migrations.md docs/specs/SPEC-006-studio-runtime-and-ui.md`
-
-Expected: the new contract text is present exactly once in each spec.
-
-### Task 2: Server contract and store
-
-**Files:**
-
-- Modify: `apps/server/src/lib/content-api/types.ts`

-
-Run: `bun test apps/server/src/lib/content-api.test.ts apps/server/src/lib/content-api.integration.test.ts`
-
-Expected: failures mentioning missing `/api/v1/content/overview` behavior.
-
-**Step 3: Write minimal implementation**
-
-- Add overview types
-- Add route handler
-- Add store method in both store implementations
-
-**Step 4: Re-run focused server tests**
-
-Run: `bun test apps/server/src/lib/content-api.test.ts apps/server/src/lib/content-api.integration.test.ts`
-
-Expected: the new tests pass.
-
-### Task 3: Studio overview consumer

-- Test: `packages/studio/src/lib/content-overview-state.test.ts`
-- Test: `packages/studio/src/lib/runtime-ui/pages/content-page.test.tsx`
-
-**Step 1: Write the failing tests**
-
-- Assert `/admin/content` uses overview counts for `total`, `published`, and
-  `drafts` even without draft-read
-- Keep permission-constrained behavior for callers with no content-read access
-
-**Step 2: Run focused Studio tests to verify failure**
-
-Run: `bun test packages/studio/src/lib/content-overview-state.test.ts packages/studio/src/lib/runtime-ui/pages/content-page.test.tsx`
-
-Expected: failures showing missing count behavior.
-
-**Step 3: Write minimal implementation**
-
-- Add Studio API client for `/api/v1/content/overview`
-- Switch count loading to the new metadata endpoint
-
-**Step 4: Re-run focused Studio tests**
-
-Run: `bun test packages/studio/src/lib/content-overview-state.test.ts packages/studio/src/lib/runtime-ui/pages/content-page.test.tsx`
-
-Expected: the new tests pass.
-
-### Task 4: Theme persistence
-
-**Files:**
-

-- Assert the provider reads an existing stored preference
-- Assert `setTheme()` persists updates
-- Assert fallback precedence honors `defaultTheme` and `enableSystem`
-
-**Step 2: Run the focused theme test to verify failure**
-
-Run: `bun test packages/studio/src/lib/runtime-ui/adapters/next-themes.test.tsx`
-

-**Step 3: Write minimal implementation**
-
-- Read/write a dedicated localStorage key
-- Apply effective dark/light class for `system`
-
-**Step 4: Re-run the focused theme test**
-
-Run: `bun test packages/studio/src/lib/runtime-ui/adapters/next-themes.test.tsx`
-
-Expected: the new tests pass.
-
-### Task 5: Verification and PR

-| 1   | HIGH     | `app-sidebar.tsx:78-82`   | **"Coming Soon" sidebar section** lists Scheduled, Audit Log, SEO Analysis. Roadmap leakage -- SPEC-006 does not define these routes. Sidebar advertises unbuilt capabilities. |
-| 2   | HIGH     | `page-header.tsx:248-255` | **"Profile" and "Preferences" user menu items** are non-functional. No onClick, no navigation target, no page exists. Dead affordances implying non-existent features.         |
-| 3   | LOW      | `app-sidebar.tsx:61`      | **API nav item uses `Search` icon** but the API page uses `Terminal`. Inconsistent.                                                                                            |

-
-### What's correct
-
-- Layout uses real APIs only (capabilities, session, environments) -- no mock-data.ts imports
-- User display from real session email with derived initials
-- Environment selector from real environment API
-- Role-gating of nav items (Schema, Users, Settings) via capabilities
-- Theme toggle, sign out, project badge all functional
-
-### Required changes
-
-- [ ] Remove the "Coming Soon" sidebar section entirely (lines 78-82, 164-225)
-- [ ] Remove non-functional "Profile" and "Preferences" from user menu (lines 248-255)
-- [ ] Align sidebar icons: API -> Terminal, Workflows -> GitBranch

----
-
-## Cross-cutting observations
-
-1. **mock-data.ts is NOT imported by any of the five audited surfaces.** Only consumed by out-of-scope pages (Users, Settings, Environments, Editor sidebar).
-
-2. **CMS-136, CMS-137, CMS-138 are clean.** Their dependency tasks (CMS-130, CMS-131, CMS-132) delivered real integrations that replaced mock behavior. No changes needed.
-
-3. **CMS-135 has 2 high-severity issues** in the shell: Coming Soon section and dead user menu items.
-
-4. **CMS-144 has the most findings** -- all three deferred pages overclaim. Media page is worst with its elaborate blurred mockup. The `<ComingSoon>` component itself needs rework.

-# CMS-67 Environment Field Badges Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Surface environment-specific field badges in the Studio document editor so editors can see which fields only exist in the active environment.
-
-**Architecture:** Derive serializable document-route metadata from the authored config, pass it through the Studio mount context, and render a badge section in the document sidebar from that metadata. Reuse the same metadata to keep the editor route aligned with the currently selected environment.
-
-**Tech Stack:** Bun, Nx, React, TypeScript, Zod runtime contract validation

-# MDCMS Integration Audit Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Audit MDCMS from an adopter's perspective by building greenfield and brownfield demo integrations in isolated temp directories, running the full local stack, and capturing concrete integration friction plus candidate abstractions.
-
-**Architecture:** Run one shared MDCMS backend/dev stack from the monorepo, then create multiple isolated temp apps under `/tmp` that consume local MDCMS packages. Assign independent temp apps to separate worker agents. Standardize each worker's findings into one comparable format so orchestration can synthesize a cross-app integration report.
-
-**Tech Stack:** Bun, Nx, Docker Compose, Next.js, Vite, React Router, local workspace package linking, MDCMS CLI/SDK/Studio
-
----
-
-### Task 1: Shared Stack Baseline
-
-**Files:**
-
-- Read: `package.json`
-- Read: `docker-compose.dev.yml`
-- Read: `apps/studio-example/README.md`
-
-**Step 1: Start the shared stack**
-
-Run:
-
-```bash
-bun run compose:dev
-```
-
-Expected: the local stack starts successfully and keeps the server, Studio runtime, and example host app in watch mode.
-
-**Step 2: Verify the stack is reachable**
-
-Run:
-
-```bash
-curl -sf http://127.0.0.1:4000/healthz
-curl -sf http://127.0.0.1:4173
-```
-
-Expected: both endpoints return success.
-
-**Step 3: Record shared environment assumptions**
-
-Record:
-
-- server URL
-- seeded login credentials
-- seeded demo API key behavior
-- any startup failures or local prerequisites
-
-### Task 2: Create Audit Workspace and Reporting Skeleton
-
-**Files:**
-
-- Create: `/tmp/mdcms-audit.<id>/README.md`
-- Create: `/tmp/mdcms-audit.<id>/findings/summary.md`
-- Create: `/tmp/mdcms-audit.<id>/findings/template.md`
-- Create: `/tmp/mdcms-audit.<id>/progress.md`
-
-**Step 1: Create the temp root**
-
-Run:
-
-```bash
-mktemp -d /tmp/mdcms-audit.XXXXXX
-```
-
-Expected: a unique audit root is created.
-
-**Step 2: Create a reporting template**
-
-Include these required sections:
-
-- app/use case
-- exact step
-- expected effort
-- actual effort
-- friction
-- why this is unintuitive vs merely undocumented
-- repeated values / boilerplate
-- candidate abstraction
-- prototype attempted?
-- blocker severity
-
-**Step 3: Create a progress tracker**
-
-Track:
-
-- each app/use case
-- owner agent
-- current state
-- blockers
-- synthesis status
-
-### Task 3: Greenfield Next.js Host
-
-**Files:**
-
-- Create: `/tmp/mdcms-audit.<id>/greenfield-next/**`
-- Modify: app files inside that temp app only
-
-**Step 1: Scaffold the app**
-
-Create a fresh Next.js app in the temp root.
-
-**Step 2: Link MDCMS packages locally**
-
-Install or link:
-
-- `@mdcms/cli`
-- `@mdcms/sdk`
-- `@mdcms/studio`
-
-**Step 3: Execute these use cases deeply**
-
-Use cases:
-
-- SDK reads from seeded content
-- Studio catch-all route embed
-- local MDX component registration
-- target/environment handling
-- auth flow and CLI-assisted content workflow
-
-**Step 4: Capture friction and prototype helper wrappers where obvious**
-
-Prototype examples may include:
-
-- centralized MDCMS config readers
-- request-header helpers
-- Studio route wrapper components
-- SDK client factory helpers
-
-### Task 4: Greenfield Vite + React Router Host
-
-**Files:**
-
-- Create: `/tmp/mdcms-audit.<id>/greenfield-vite/**`
-- Modify: app files inside that temp app only
-
-**Step 1: Scaffold the app**
-
-Create a fresh Vite React app with React Router.
-
-**Step 2: Link MDCMS packages locally**
-
-Install or link:
-
-- `@mdcms/cli`
-- `@mdcms/sdk`
-- `@mdcms/studio`
-
-**Step 3: Execute these use cases deeply**
-
-Use cases:
-
-- SDK reads from seeded content
-- admin route integration
-- Studio embed attempt outside Next.js
-- environment/target handling
-- auth and CLI workflow from a non-Next host
-
-**Step 4: Capture friction and prototype helper wrappers where obvious**
-
-Pay special attention to anything that claims framework agnosticism but still assumes Next.js ergonomics.
-
-### Task 5: Brownfield Next.js Markdown App
-
-**Files:**
-
-- Create: `/tmp/mdcms-audit.<id>/brownfield-next/**`
-- Create: markdown content tree under that temp app
-- Modify: app files inside that temp app only
-
-**Step 1: Scaffold an app that already renders local markdown**
-
-Create:
-
-- content routes
-- filesystem content loader
-- a representative markdown tree
-
-**Step 2: Run `mdcms init` end to end**
-
-Use a unique `(project, environment)` pair for this app.
-
-**Step 3: Execute these use cases deeply**
-
-Use cases:
-
-- schema inference from existing markdown
-- locale detection/remapping
-- gitignore/untracking implications
-- preserving existing content routes while adopting MDCMS
-- adding Studio to an app with existing route/layout assumptions
-
-**Step 4: Migrate one content surface to MDCMS-backed reads**
-
-Compare:
-
-- old local markdown read path
-- direct API path
-- SDK path
-
-### Task 6: Brownfield Vite + React Router Markdown App
-
-**Files:**
-
-- Create: `/tmp/mdcms-audit.<id>/brownfield-vite/**`
-- Create: markdown content tree under that temp app
-- Modify: app files inside that temp app only
-
-**Step 1: Scaffold an app that already renders local markdown**
-
-Create:
-
-- routed pages
-- filesystem content loader
-- representative markdown and MDX-ish content
-
-**Step 2: Run `mdcms init` end to end**
-
-Use a unique `(project, environment)` pair for this app.
-
-**Step 3: Execute these use cases deeply**
-
-Use cases:
-
-- schema inference from existing markdown
-- preserving route compatibility
-- SDK migration path
-- admin route integration
-- Studio embed attempt in a non-Next brownfield host
-
-**Step 4: Compare migration burden**
-
-Measure:
-
-- duplicated config
-- repeated target/auth wiring
-- manual manifest/content mapping assumptions
-
-### Task 7: Additional Targeted Use Cases
-
-**Files:**
-
-- Create: `/tmp/mdcms-audit.<id>/cases/**`
-
-**Step 1: Add at least two focused mini-cases if needed**
-
-Examples:
-
-- single-locale markdown app
-- multi-locale markdown app with suffix/folder mismatch
-- MD vs MDX mixed tree
-- host app with custom base path or existing admin route namespace
-
-**Step 2: Use mini-cases only where a major finding needs sharper reproduction**
-
-Do not create extra apps unless they expose materially different friction.
-
-### Task 8: Standardized Worker Reporting
-
-**Files:**
-
-- Create: `/tmp/mdcms-audit.<id>/findings/*.md`
-
-**Step 1: Require every worker to produce one report per app**
-
-Each report must include:
-
-- what worked
-- what felt tedious
-- what felt unintuitive even with hypothetical docs
-- what values had to be repeated
-- what glue code should probably live in MDCMS library code
-- what helper the worker prototyped locally
-
-**Step 2: Require exact code references inside the temp app**
-
-The report must point to the concrete files that demonstrate the issue.
-
-### Task 9: Cross-Cutting Improvement Prototypes
-
-**Files:**
-
-- Modify: temp app helper files only
-
-**Step 1: Choose the highest-signal pain points**
-
-Examples:
-
-- repeated `project/environment/serverUrl` wiring
-- repeated auth header creation
-- server-component/client-component split for Studio config
-- manual MDX component metadata stripping/re-merging
-
-**Step 2: Prototype small wrappers**
-
-Examples:
-
-- `createMdcmsRuntimeConfig(...)`
-- `createScopedFetcher(...)`
-- `createStudioRoute(...)`
-- `createDemoSdkClient(...)` generalized beyond the demo app
-
-**Step 3: Keep prototypes local to temp apps**
-
-The audit should demonstrate better ergonomics without changing the monorepo implementation yet.
-
-### Task 10: Final Synthesis
-
-**Files:**
-
-- Create: `/tmp/mdcms-audit.<id>/findings/final-report.md`
-
-**Step 1: Build the use-case matrix**
-
-Columns:
-
-- use case
-- app
-- status
-- friction summary
-- blocker summary
-- candidate MDCMS fix
-
-**Step 2: Prioritize findings**
-
-Buckets:
-
-- abstraction gap
-- config duplication
-- routing/embed friction
-- migration friction
-- framework-specific leakage
-
-**Step 3: Distinguish findings carefully**
-
-Do not include:
-
-- pure documentation gaps
-
-Do include:
-
-- concepts that remain awkward even with documentation
-- repeated boilerplate
-- unnecessary manual integration code
-- surprising contracts and split responsibilities
-
-**Step 4: Deliver the audit**
-
-Return:
-
-- completed matrix
-- prioritized findings
-- concrete examples
-- prototype wrapper examples
-- residual gaps not exercised

-# Real Scenario MDCMS Audit Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Replace the current technical-slice MDCMS test-integrations repo with 10 real product scenarios arranged as 5 mirrored greenfield/brownfield pairs, then run the full integration flow for each and capture real adopter friction.
-
-**Architecture:** Use one shared local MDCMS stack, one target repo clone at `/tmp/mdcms-test-integrations`, and fresh temp workspaces per scenario pair. Each worker owns one mirrored domain pair so greenfield and brownfield remain comparable. The controller verifies repo shape, reviews friction findings for adopter relevance, and pushes only after the repo and reports reflect the real-scenario matrix.
-
-**Tech Stack:** Bun, Nx, Docker Compose, Next.js, Vite, React Router, MDCMS CLI, MDCMS SDK, MDCMS Studio, local workspace package linking
-

-- repeated values and source-of-truth problems
-- manual integration glue that should live in MDCMS
-- unintuitive contracts even with hypothetical docs

-### User
-
-Can you tes connection to figma mcp
-
-### Assistant
-
-I’m checking the local Codex setup first so I can verify whether a Figma MCP server is configured and responding, then I’ll try a lightweight MCP call against it.
-
-### Assistant
-
-Using `using-superpowers` to follow the required skill-loading workflow before I inspect the MCP setup. Next I’m querying the configured MCP servers to see whether a Figma server is present and reachable.
-
-### Assistant
-
-The MCP registry isn’t exposing any resources or templates right now, which usually means either no server is configured for this session or the server failed to register. I’m checking the local MCP config next for any Figma entry and then I’ll try to confirm whether the process can actually start.
-
-### Assistant
-
-The local config looks like it used to have a `figma` MCP entry, but the current active config may not. I’m reading the active `~/.codex/config.toml` block directly and then I’ll probe the local Figma MCP URL if it still exists anywhere.
-
-### Assistant
-
-The endpoint itself is alive on `127.0.0.1:3845`; the `400` on a plain `GET` is expected for many MCP HTTP servers because they require a JSON-RPC request. I’m sending a minimal `initialize` call now to confirm whether the server speaks MCP properly.
-
-### Assistant
-
-The server completed `initialize` successfully and identified itself as `Figma Dev Mode MCP Server 1.0.0`. I’m doing one more protocol-level check by opening a session properly and asking for its tool list.
-
-### Assistant
-
-I tested it directly.
-
-- `http://127.0.0.1:3845/mcp` is reachable from this machine.
-- A proper MCP `initialize` request returned `200 OK` and identified itself as `Figma Dev Mode MCP Server` version `1.0.0`.
-- A follow-up `tools/list` call also succeeded and exposed tools including `get_design_context`, `get_variable_defs`, `get_screenshot`, `get_metadata`, `create_design_system_rules`, and `get_figjam`.
-
-One caveat: the active Codex config at [config.toml](~/.codex/config.toml) does not currently contain a `figma` MCP entry, so this session is not wired to use it through the built-in MCP registry yet. That matches the empty MCP resource/template listing I saw.
-
-If you want, I can add the Figma MCP entry back into [config.toml](~/.codex/config.toml) and tell you the exact restart step needed for Codex to pick it up.
-
-### User
-
-okay can you get the currently selected frame i have i want you to see the section "three decisions. everything else follows." and brainstorm ideas for copy for that section with be - both for the paragraphs/headers AND the embedded terminal views - we want something in the terminal that matches our actual experience and makes sense
-
-### Assistant
-
-Using `brainstorming` to shape the copy options before writing them. I’m pulling the currently selected Figma node through the MCP server now so I can inspect that section and make the terminal content match what’s actually on the screen.
-
-### Assistant
-
-I have the MCP server up; now I’m reading the currently selected node’s metadata and screenshot so the copy options track the real structure, not a guess. After that I’ll ask one narrow question about tone before I draft directions.
-
-### Assistant
-
-The MCP server is healthy, but the selected-node calls are being rejected by Figma with an access error. Please make sure your paid Figma seat includes Dev Mode access, you have permission to that file, and then send me the link to that exact frame or reselect it and tell me when it’s active.
-
-### Assistant
-
-The MCP connection works, but Figma refused access to the currently selected node, so I can’t see that section yet.
-
-Please make sure your paid Figma seat includes Dev Mode access, you have permission to that file, and then send me the link to that exact frame or reselect it and tell me when it’s active. Once I can read it, I’ll give you 2-3 copy directions for the header, paragraph, and realistic terminal content that matches the actual product experience.
-
-### User
-
-ok just see this then
-
-`<image>…screenshot of the “Three decisions. Everything else follows.” section with three numbered cards and repeated terminal snippets…</image>`
-
-### Assistant
-
-I can see the issue now: the three cards are carrying distinct architecture claims, but the terminal panels all repeat the same `init`/`validation` snippet, so only one of them even loosely matches the copy. The first choice I need from you is audience: is this section aimed primarily at CTO/engineering leads evaluating architecture, or hands-on developers who would actually use the CLI day to day?

-Read this convo to see what we mainly need to change here

-Karol Chudzik [9:00 AM]
-Mógłbyś mi powiedzieć jeszcze czego konkretnie potrzeba ode mnie w tym copy? W sensie po prostu powiedzieć czy to jest zgodne z prawdą to co tam piszemy i zrobić te snippety do terminala, czy wymyślić w ogóle od nowa? Bo imo to zależy konkretnie co chcemy podkreślić i jak to pozycjonować. Ale dla mnie "database is source of truth" nie ma sensu i nie widzę kogo miałoby to w ogóle interesować w jaki sposób przechowujemy ten content, a punktu "every interface is a full client" sam nie rozumiem o co w nim chodzi
-Karol Chudzik [9:15 AM]
-I do designu który task jest aktualny CMS-160 czy CMS-179 bo są dwa
-Saved for laterJakub Jabłoński [10:21 AM]
-replied to a thread:Wymyślić od nowa dla tej sekcji o której mówiłem bo tak ja mówisz jest z dupy
-
-Snippets z terminala dla sekcji wyżej z Content Codebase i Config
-
-### Assistant
-
-Using `brainstorming` to pin down what this section actually needs to communicate before drafting replacement copy. I’m extracting the concrete ask from the thread and then I’ll narrow the replacement direction with one question.
-
-### Assistant
-
-Main read from that thread: this is not a fact-check or light polish pass. It needs a full rewrite.
-
-What needs to change:
-
-- Jakub explicitly wants this section reinvented from scratch.
-- The current angle is wrong because it leads with internals instead of a meaningful promise.
-- `Database is the source of truth` was called out as not interesting or persuasive.
-- `Every interface is a full client` was called out as unclear even internally.
-- The repeated terminal panels are also in the wrong place. Jakub wants terminal snippets for the section above, around `Content Codebase` and `Config`, not for this `Three decisions` block.
-- The convo does not resolve the `CMS-160` vs `CMS-179` question.
-
-So the real task here is: replace this section with a clearer positioning idea, and move the terminal-proof moments to the section above where they actually support the message.
-
-If we replace this section entirely, what single promise do you want it to sell?
-
-### User
-
-No the terminals should be in this section as well, the terminals is a different thing we will come back to that in a bit, the layou should stay teh same
-
-Header
-Paragraph
-
-- termianl snippet
-
-`<image>…cropped screenshot of one card showing header, paragraph, and terminal snippet layout…</image>`
-
-### Assistant
-
-Layout stays: each block remains `header + paragraph + terminal snippet`. The change is the message, not the structure, and the terminals still need to support each block instead of repeating the same generic `init` output.
-
-### Assistant
-
-One question to pin the direction down: should these three blocks explain internal architectural decisions, or should they translate those decisions into buyer-facing outcomes?
-
-My recommendation is buyer-facing outcomes, because the current problem is exactly that the copy sounds like implementation notes instead of a reason to care.

-
-My recommendation is buyer-facing outcomes, because the current problem is exactly that the copy sounds like implementation notes instead of a reason to care.
-
-### User
-
-yes outcomes
-
-### Assistant
-
-I have the direction now: keep the layout, but rewrite each card around outcomes instead of internals. I’m checking the existing docs and site copy so the new claims stay defensible and the terminal snippets map to real product behaviors.
-
-### Assistant
-
-The docs are useful here because they expose a more convincing message than the current copy: the real product truths are about explicit schema control, file-based workflows, and shared routing/contracts across CLI, Studio, and SDK. I’m doing one last pass on the existing marketing/source files to see whether the brand voice prefers `cms`, `mdcms`, or `arch.cms` in terminal examples before I draft the options.
-
-### Assistant
-
-Three viable directions for this section, all outcome-led and grounded in the actual product:
-
-1. **Operate content like software**. Recommended.
-
-- Why it works: this is the clearest bridge between the product truth and the buyer outcome. MDCMS really does use code-defined schema, explicit sync, and shared server contracts.
-- What the three cards would emphasize:
-  - schema changes are explicit and reviewable
-  - content workflows stay predictable across local files and the backend
-  - CLI, Studio, and SDK all act on the same project/environment scope
-- Terminal feel:
-  - `mdcms schema sync`
-  - `mdcms pull`
-  - `mdcms status` or `mdcms push --dry-run`
-- Trade-off: slightly more technical, but it sounds like a serious tool instead of generic CMS marketing.
-
-2. **No hidden state**
-
-- Why it works: this turns the section into a contrast story. No secret schema editor, no silent drift, no special admin path.
-- What the cards would emphasize:
-  - structure lives in config you can inspect
-  - writes fail loudly when schema is out of sync
-  - every surface follows the same rules
-- Terminal feel:
-  - schema hash mismatch guidance
-  - pull plan output
-  - scoped status output
-- Trade-off: sharper and more memorable, but more negative in tone.
-
-3. **Move faster without losing control**
-
-- Why it works: broader and more buyer-friendly. It translates architecture into team outcomes instead of implementation details.
-- What the cards would emphasize:
-  - faster setup and safer iteration
-  - fewer surprises between local and remote state
-  - consistent behavior across tools and teammates
-- Terminal feel:
-  - concise setup/sync confirmation
-  - dry-run plan
-  - target scope confirmation
-- Trade-off: easiest to read, but also the most likely to drift into generic SaaS copy.
-
-My recommendation is **Operate content like software**. It gives you a strong headline system, matches the repo truth, and gives the terminal snippets something concrete to prove.
-
-One important detail: if these terminals are meant to feel real, I would switch them to `mdcms` or `cms`, because that is what the repo/docs actually define. `arch.cms` reads like marketing fiction unless that alias really exists.
-
-If this direction looks right, I’ll turn it into actual replacement copy for all three cards: header, paragraph, and matching terminal snippet.
-
-### User
-
-"Operate content like software" I don't feel like this makes ton of sense like what does this even mean? is this just advertising our cli interface or what
-
-### Assistant
-
-You’re right. That phrase is too vague, and it drifts toward “look, we have a CLI,” which is not the point of the section. The terminal should be proof of the operating model, not the thing being sold.
-
-### Assistant
-
-You’re right. That phrase is too vague, and it drifts toward “look, we have a CLI,” which is not the point of the section.
-
-What this section should probably sell instead is one of these clearer outcomes:
-
-1. **Content changes stay controlled**
-
-- Meaning: schema changes are explicit, reviewable, and don’t happen through a hidden admin UI.
-- Good if you want to position against messy CMS sprawl.
-
-2. **Teams don’t lose each other’s work**
-
-- Meaning: editors, developers, and automation can all work in parallel without creating drift or mystery state.
-- Good if you want the section to feel more collaborative and less infra-heavy.
-
-3. **Every tool follows the same rules**. Recommended.
-
-- Meaning: Studio, CLI, and SDK are different interfaces to the same system, so behavior is consistent instead of fragmented.
-- This is clearer than “every interface is a full client,” but says the same thing in plain English.
-
-So no, I would not frame this as “we have a CLI.” I’d frame it as:
-
-- predictable changes
-- less drift/conflict
-- consistent behavior across surfaces
-
-The terminal then becomes evidence for each claim:
-
-- explicit sync
-- explicit pull/push/status
-- explicit scoped behavior
-
-Which of those three outcomes do you want the section to emphasize most: control, collaboration, or consistency?
-
-### User
-
-also i feel like the configuration as code point should stay because it is a unique selling point i think
-
-### Assistant
-
-Yes. I would keep that point.
-
-The issue is not `configuration as code` itself. The issue is that `Configuration lives in code.` reads like an implementation detail instead of a reason to care.
-
-That card should probably keep the mechanism, but sell the outcome:
-
-- `Change structure in code. Review it like code.`
-- `Your content model lives in the repo.`
-- `No hidden schema editor.`
-
-And the paragraph can translate why that matters:
-
-- content types and fields are defined in `mdcms.config.ts`
-- changes go through the same review flow as the rest of the product
-- Studio reflects the config, but does not become a second place where structure can drift
-
-So I’d treat this as:
-
-- one card can stay explicitly about config-as-code, because it is distinctive
-- the other two cards should be outcome-first, not architecture-notes-first
-
-A cleaner shape for the three cards could be:
-
-1. Config as code
-2. Content changes stay in sync
-3. Every surface follows the same rules
-
-For the config card alone, my recommendation is this direction:
-
-Header:
-`Your content model lives in code.`
-
-Paragraph:
-`Types, fields, and environment rules are defined in \`mdcms.config.ts\`, not rebuilt in an admin panel. The Studio reads that config, so structure changes stay reviewable and ship through the same workflow as the rest of your app.`
-
-One question: do you want that card to say `code` explicitly in the header, or keep the header more benefit-led and move `mdcms.config.ts` into the paragraph only?
-
-### User
-
-i like this one Your content model lives in the repo.
-
-### Assistant
-
-That header works. I’m validating the matching terminal proof against the actual CLI now so the snippet feels like something the product would really say, not placeholder console noise.
-
-### Assistant
-
-I found the real CLI surfaces we can lean on. `schema sync`, `status`, `pull`, and `push --dry-run` all print concrete, product-specific output, so we can make the terminal panels feel legitimate instead of fabricated.
-
-### Assistant
-
-I’m locking this card first before touching the other two. The strongest version is to keep the repo angle in the header, then make the paragraph explain why that matters operationally, with `schema sync` as the proof.
-
-### Assistant
-
-For that card, I’d tighten it to this:
-
-Header:
-`Your content model lives in the repo.`
-
-Paragraph:
-`Types, fields, and environment rules live in \`mdcms.config.ts\`, so structure changes go through pull requests instead of a hidden schema editor. The Studio reads the same config, which keeps your model versioned, reviewable, and aligned with the app it serves.`
-
-Terminal:
-
-```text
-$ mdcms schema sync
-Schema synced (hash: 8f3c1b7a2d41)
-Affected types: BlogPost, Author, Page
-```
-
-This feels right because the header is outcome-first, but the terminal proves a real mechanism instead of hand-wavy “developer experience” copy. The snippet also matches the actual CLI shape, so it won’t read fake.
-
-If this card looks right, I’ll draft the second one next.

-# Grouped Content List Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Add grouped localized content rows to the content list API and Studio `/admin/content/:type` so localized logical documents render once per translation group.
-
-**Architecture:** Extend the existing `GET /api/v1/content` contract with `groupBy=translationGroup` for localized types, aggregate rows server-side after filtering and before pagination, then update Studio's content list client and type list UI to consume grouped entries instead of raw locale documents. Keep non-localized behavior unchanged.
-
-**Tech Stack:** Bun, Nx, TypeScript, Bun test, Studio React runtime, server content API/database store.

Subject: [PATCH 4/7] chore(ai-harness): drop Nx-MCP integration entirely

The Nx-MCP setup was Karol's local Codex configuration, not something
the team uses uniformly. Per the principle that committed files must
make sense for any contributor cloning the repo, removing:

- `.ai/memory/integrations/nx-mcp.md`
- `.codex/config.toml` (and the empty `.codex/` directory it left behind)
- References to Nx-MCP in `AGENTS.md` and `.ai/memory/{README,integrations/README}.md`

Codex CLI users can configure their own MCP servers via `~/.codex/`
without per-project config in this repo.

-# Nx MCP
-
-## What it is + why
-
-`nx-mcp` is an MCP server that exposes Nx workspace operations (project graph, target running, generator listing) to AI agents. It lets agents reason about the monorepo's structure and run Nx commands without invoking the Nx CLI directly.
-
-## Configuration
-
-Defined in `.codex/config.toml` (committed):
-
-```toml
-[mcp_servers.nx-mcp]
-command = "npx"
-args = [ "nx-mcp@latest", "--minimal" ]
-```
-
-The `--minimal` flag scopes the server to lightweight operations (project-graph reads) without enabling heavier features.
-
-## How agents interact
-
-Codex CLI loads the MCP server on session start. Tools exposed include workspace project listing, target running, and generator listing.
-
-Other agent harnesses (Claude Code, Cursor) load MCP servers from their own per-tool configuration files outside the repo.
-
-## Failure modes
-
-- **`npx nx-mcp@latest` fails to install** — usually a network issue. Run `npx nx-mcp@latest --help` manually to surface the underlying error.
-
-## Cross-refs

Subject: [PATCH 5/7] chore(ai-harness): remove ROADMAP_TASKS.md references
 from committed docs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`ROADMAP_TASKS.md` is a local-only file that doesn't exist on a fresh
clone. Per the principle that committed docs must make sense for any
contributor, removing every reference to it from `AGENTS.md`,
`.ai/memory/README.md`, `.ai/memory/architecture.md`, and
`.ai/memory/initiatives/README.md`.

Replacements use generic phrasing ("the issue tracker", "the linked
issue", "task's acceptance criteria") so the rules still apply
regardless of which planning tool the team happens to use.

The `.gitignore` entry for `ROADMAP_TASKS.md` stays — that's the
mechanism that keeps it from being committed accidentally; nothing in
committed docs references it anymore.

- `AGENTS.md` package-boundary list — varied verbs (Place / live in /

- `AGENTS.md` rule #7 — added Windows symlink caveat noting that
  POSIX-style symlinks may not check out cleanly without developer
  mode or `core.symlinks=true`, with a fallback to junctions or a
  recursive copy of `.ai/skills/`.
