From ec5325f964bb33b325380c4cf30d7dbf5e618076 Mon Sep 17 00:00:00 2001 From: Contentrain Date: Fri, 17 Apr 2026 21:46:58 +0300 Subject: [PATCH 1/2] fix(serve,mcp,cli): serve correctness + MCP helper surface + secure-by-default auth MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Consolidates a four-agent review of `contentrain serve` and the MCP helpers it consumes. Fixes drift, ships the UI affordances that make the fixes visible, hardens auth, and eliminates ~300 lines of duplicated merge/diff logic by delegating to MCP. ### MCP — public helpers + empty-repo init - New `branchDiff(projectRoot, { branch, base? })` exported from `@contentrain/mcp/git/branch-lifecycle`. Defaults `base` to `CONTENTRAIN_BRANCH` — the singleton content-tracking branch every feature branch forks from. Replaces the CLI's duplicated `git.diff([${defaultBranch}...${branch}])` calls, which surfaced unrelated historical content changes once contentrain advanced past the repo's default branch. - `tools/setup.ts` `contentrain_init` now handles greenfield directories: seeds an `--allow-empty` initial commit when the repo has zero commits so `ensureContentBranch` has a base ref to anchor on. Previously the CLI `init` command created this commit manually while the MCP tool skipped the step — the tool failed on an empty directory the CLI handled fine. - Tests: new `tests/git/branch-lifecycle.test.ts` (3 cases) + new setup case (`initialises a greenfield directory with no .git and no commits`). ### Serve server — correctness + new routes + auth - Three duplicated merge-via-worktree implementations (`/api/branches/approve`, `/api/normalize/approve`, CLI `diff`) replaced with calls to MCP's `mergeBranch()` helper. Runs the worktree transaction with selective sync + dirty-file protection. Skipped files are cached and surfaced to the UI via a new `sync:warning` WebSocket event and a new `/api/branches/:name/sync-status` route. Merge conflicts now broadcast `branch:merge-conflict` instead of silently succeeding. - `/api/branches/diff` delegates to the new `branchDiff()` helper with CONTENTRAIN_BRANCH as the default base. - History filter tolerates BOTH legacy `Merge branch 'contentrain/'` and current `Merge branch 'cr/'` commit patterns so post-Phase-7 history doesn't drop merges. - `.catch(() => {})` error-swallowing at three sites removed. Merge conflicts and cleanup failures no longer pretend to succeed. - Normalize plan approve broadcasts `branch:created` on the returned `git.branch` metadata (parity with content save route). - New `/api/capabilities` route — provider type, transport, capability manifest, branch health, repo info in one call. Dashboard consumes this to render the capability badge. - New `/api/branches/:name/sync-status` — on-demand sync warning fetch for the branch detail page; 1h TTL cache in memory. - New WebSocket events: `branch:rejected`, `branch:merge-conflict`, `sync:warning`. - Zod input validation on every write route via new `serve/schemas.ts`. Catches malformed bodies with structured 400 errors before they reach the MCP tool layer. Adds `zod` as a direct CLI dependency. - `serve` command — secure-by-default auth. Binding to a non-localhost interface now HARD ERRORS when no `--authToken` is set. No `--allow-unsafe` opt-out flag (OWASP Secure-by-Default; matches Postgres, helm, kubectl port-forward conventions). ### Serve UI — level-ups that make the fixes visible - `useWatch.ts` — WSEvent union widened for the new event types (branch:rejected, branch:merge-conflict, sync:warning, connected). - `project` store — `capabilities` state + `branchHealthAlarm` computed + `fetchCapabilities()` action. - `AppLayout` — global branch-health banner (warning / blocked thresholds from MCP), sync-warning toasts with "View details" action deep-linking to the branch detail page, merge-conflict toasts with the failure message. - `DashboardPage` — capability badge (provider type · transport) next to the workflow + stack badges. - `BranchDetailPage` — sync warnings panel listing every file the selective sync skipped and why, rendered only when the last mergeBranch() call produced warnings. - `ValidatePage` — issues are now clickable when a `model` is present; deep-links to the content list filtered to the issue's `locale` / `id` / `slug`. Fallback to the model list for aggregate issues (e.g. i18n parity). ### CLI — delegation to MCP helpers - `commands/diff.ts` — both the per-branch summary line and the merge confirmation call `branchDiff()` / `mergeBranch()` from MCP. Surfaces `sync.skipped[]` warnings to the user with the list of preserved files. Removes the duplicated `contentrain` branch + worktree + update-ref + checkout dance (~45 lines). - `commands/doctor.ts` — branch health check delegates to MCP's `checkBranchHealth()`. Previously filtered `contentrain/*` directly after the Phase 7 naming migration to `cr/*`, so the check silently reported "None" no matter how many branches had accumulated. The delegation uses MCP's canonical thresholds (warn at 50, block at 80). - `commands/validate.ts` non-interactive path — captures `tx.complete()` result and surfaces the branch name + workflow action in review mode. Previously this metadata was dropped; the user ran `contentrain validate --fix`, saw "fixed 3 issues", and had no indication that the fix landed on a `cr/fix/validate/...` branch that needed manual review. ### Verification - `pnpm -r typecheck` → 0 errors across 8 packages. - `oxlint` monorepo → 0 warnings across 399 files. - `vue-tsc --noEmit` serve-ui → 0 errors. - `pnpm --filter @contentrain/mcp build` + `pnpm --filter contentrain build:cli-only` → clean. - MCP fast suite → 443/443 green, 2 skipped. ### Tool surface No changes. Same 16 MCP tools, same arg schemas, same JSON response shapes. Stdio + LocalProvider flows behave identically to the previous release. ### Changeset `.changeset/phase-13-serve-correctness-levelup.md` — minor bump for both `@contentrain/mcp` (new `branchDiff` export, empty-repo init fix) and `contentrain` (new serve capabilities + secure auth + zod dependency).

Rewritten to mock `@contentrain/mcp/git/branch-lifecycle` branchDiff + `@contentrain/mcp/git/transaction` mergeBranch, assert the delegation, and use `cr/*` branch naming throughout. - `tests/commands/serve.test.ts` — mocked consola without `.error`, so the new "refuse to start on 0.0.0.0 without --authToken" path crashed at `consola.error(...)`. Mock now includes `error`; the existing `--host 0.0.0.0` test passes `authToken` to exercise the success path; a new test asserts the hard-error path. - `tests/integration/serve.integration.test.ts` — asserted the old merge-via-worktree dance (worktree add + update-ref + checkout). Rewritten to mock the MCP helpers instead, verify the delegation call shapes, and assert `sync:warning` + `branch:merge-conflict` WS broadcasts land on the fake client. CI target: `contentrain` package vitest run → 119/119 green (previously 111/117 with 6 failures; 8 new assertions added for the secure-auth + merge-conflict + sync-warning paths).
