 ### Changed
 
+- **Restructured to the ratified neutral architecture (META-236 → META-247).**
+  `packages/cli/` is now `@workspacejson/cli`, the neutral producer with binary
+  `workspacejson`. `packages/agents-audit/` became
+  `packages/agents-audit-compat/`, a frozen compatibility bridge that keeps the
+  `agents-audit` package name, binary, commands and all nine public exports and
+  delegates generation to the neutral package. The migrated DataHub/dbt adapter
+  moved to `packages/datahub-adapter/` and is staged pending extraction to
+  `workspacejson/datahub-agent` (META-248) — it is not durable architecture
+  here. Compatibility was proven by the parity harnesses; the only behavioral
+  difference is the ratified vendor-notice change, recorded in
+  `migration/parity-expected-differences.txt`.
+- **The CLI now compiles against real standard-owned types (META-244).** A
+  handwritten `declare module '@workspacejson/spec'` in `types/ambient.d.ts`
+  shadowed the published declarations and hid the entire v0.4 contract —
+  `WorkspaceJsonV4`, `validateV4`, `CoChangeEntry`, `FragilityEntry` — from this
+  repository's compiler. Removed, with a guard rejecting reintroduction.
+- **Parity harnesses are now executable gates, enforced in CI.** They previously
+  exited 0 regardless of result. They now fail when the set of differences
+  changes in either direction — a new difference, or a ratified one silently
+  disappearing.

 ### Patch Changes
 
+- **Changed:** `scan` no longer prints a vendor notice when `.agents/workspace.json` is missing or stale. It now names the command that actually fixes the problem — `agents-audit generate` — and still reports the same validation errors. Ratified in META-236: vendor promotion never enters the neutral producer, and is removed or made opt-in in this compatibility package. Exit codes are unchanged and `scan --json` output is byte-identical, so nothing consuming machine-readable output is affected. Human-readable `scan` output does change; this is recorded as an intentional difference in `migration/parity-expected-differences.txt` and enforced by the CI parity gate.
+- **Added:** `renderMissingArtifactNotice`, the neutral replacement used by `scan`. `renderVrekoUpsell` remains exported and unchanged for API compatibility — it is simply no longer called by the CLI, so callers who want it can still invoke it. This export set is additive; no historical export was removed.
 - `generate --check --dry-run` now fires the drift gate (exit 1, "manual evidence is untouched") instead of the dry-run branch silently winning and exiting 0; the JSON projection is still printed under `--dry-run`. Deferred from 0.4.4 (META-157) because it changes exit-code semantics; landed here as its own reviewed change with regression tests watched red against the pre-change CLI.
 - `generate` now surfaces `invalidFileMoved` (result data that has existed since 0.4.3 but was never displayed): when a previous `.agents/workspace.json` was invalid and moved aside, the CLI prints where it was relocated to and that its manual evidence could not be recovered.

+# Changelog — `@workspacejson/cli`
+
+## [Unreleased]
+
+**This package has never been published.** It is not on npm, and must not be
+documented as installable until the coordinated publish-authority cutover
+(META-243). The working public command today is `npx agents-audit generate`,
+which runs this same producer implementation.
+
+### Added
+
+- Initial package: the neutral workspace.json producer, binary `workspacejson`.
+  Created in META-247 from the implementation ratified in META-236.
+- `src/producer/` — deterministic generation, repository scanning,
+  reconciliation, manual-evidence preservation, atomic writes and drift
+  detection. Harvested from `agents-audit`'s `generate.ts`, which had no
+  dependency on the audit product and moved wholesale.
+- `src/commands/` — public command routing. `agents-audit` invokes the same
+  `runGenerate` implementation, so the two binaries cannot drift apart during
+  the compatibility window.
+- `generateWorkspaceJson` accepts a caller-supplied `producer` identity, written
+  to `generated.by`. It defaults to this package; `agents-audit` passes its
+  historical identity so its artifacts remain byte-identical. `generated.by` is
+  excluded from the material projection, so this never affects drift detection.
+- `generateWorkspaceJson` accepts a caller-supplied `commandName`, used in
+  refusal and remediation messages. Previously these hardcoded `agents-audit`,
+  which would have told a `workspacejson` user to run a different tool.
+
+### Notes
+
+- Config-file support is deliberately absent. `agents-audit` reads
+  `.agentsauditrc`, an audit-shaped name the neutral producer should not
+  inherit; naming a neutral config file is a public-surface decision left to the
+  OSS polish work (META-245).
+- Contracts come from `workspacejson/standard` as released packages
+  (`@workspacejson/spec`, `@workspacejson/rules`), pinned to exact versions.
+  This package implements the contract; it does not define it.
