add plate ui changelogs 53 52

Objective: Add the missing Plate UI registry changelog entries for v53 and v52.

Completion threshold:

• tooling/data/plate-ui-changelog.mdx represents every detected v53/v52 registry-changing PR from the release-index audit.
• apps/www/src/registry/changelog/* is regenerated from the MDX source.
• Generated index data contains the expected PR set: 4762, 4792, 4800, 4811, 4814, 4872, 4876, 4891, 4902, 4912, 4930, 4941, 4945, 4987, and 4989.
• /docs/releases serves with the generated Plate UI cards.

Verification surface:

• node tooling/scripts/generate-ui-changelog-entries.mjs --write
• node --test tooling/scripts/generate-ui-changelog-entries.test.mjs
• generated changelog index/components JSON inspection
• pnpm lint:fix
• HTTP proof for http://localhost:3000/docs/releases
• node .agents/skills/autogoal/scripts/check-complete.mjs docs/plans/2026-06-06-add-plate-ui-changelogs-53-52.md

Constraints:

• Do not add package .changeset files for registry-only changelog data.
• Do not modify registry component source.
• Preserve unrelated local changes in the checkout.

Boundaries:

• Edited source: tooling/data/plate-ui-changelog.mdx.
• Edited generator: tooling/scripts/generate-ui-changelog-entries.mjs.
• Edited test: tooling/scripts/generate-ui-changelog-entries.test.mjs.
• Generated output: apps/www/src/registry/changelog/*.
• Goal plan: this file.

Blocked condition: No blocker remains. GitHub provenance and local release-index data were available.

Start Gates:

Gate	Applies	Evidence
Active goal	yes	get_goal returned the active goal for this plan
Source of truth	yes	Read tooling/data/plate-ui-changelog.mdx and generator source
Release artifact	yes	Registry changelog only; no package .changeset
Browser surface	yes	/docs/releases on the running local docs server
Tracker sync	no	No issue or Linear tracker attached
Branch handling	no	User did not ask for commit, push, or PR
Agent-native review	no	No agent skill or rule source edited in this task

Work Checklist:

• Audit set identified from v52/v53 release data and registry-changing PRs.
• Missing source rows added to tooling/data/plate-ui-changelog.mdx.
• Generator repaired to prefer explicit changelog commit hints over git blame.
• Generator test updated for the expanded source fixture.
• Registry changelog JSON regenerated.
• Generated index verified against the expected PR set.
• Component lookup verified for representative affected registry items.
• Lint fixer run.
• Releases route verified over HTTP.
• No package changeset added because this is registry changelog data only.

Completion Gates:

Gate	Applies	Required action	Evidence
Registry changelog source	yes	Update MDX source and generated JSON	Source has v53/v52 rows; generator wrote 15 events
Generator correctness	yes	Test changed generator behavior	node --test tooling/scripts/generate-ui-changelog-entries.test.mjs passed
Missing PR audit	yes	Compare generated PRs with audit set	missing [], extra []
Lint	yes	Run repo lint fixer	pnpm lint:fix checked 3266 files
Browser proof	yes	Verify route response and rendered content	curl returned 200 text/html; HTML contains Plate UI cards
Package changeset	no	Record reason	Registry-only generated changelog data, no package runtime/API delta
PR/tracker sync	no	Record reason	User did not request PR; no tracker attached

Phase / pass table:

Phase	Status	Evidence	Next
Audit	complete	15 expected PRs recorded	implementation complete
Implementation	complete	MDX, generator, test, generated JSON updated	verification complete
Verification	complete	tests, lint, JSON audit, HTTP proof	closeout
Closeout	complete	plan evidence recorded	final response

Verification evidence:

• node tooling/scripts/generate-ui-changelog-entries.mjs --write wrote 15 registry changelog events from 30 source rows.
• Generated index.json contains PRs 4762, 4792, 4800, 4811, 4814, 4872, 4876, 4891, 4902, 4912, 4930, 4941, 4945, 4987, and 4989 with no missing or extra PRs.
• node --test tooling/scripts/generate-ui-changelog-entries.test.mjs passed 7 tests.
• pnpm lint:fix completed.
• curl -sS -o /tmp/plate-releases.html -w '%{http_code} %{content_type}\n' http://localhost:3000/docs/releases returned 200 text/html; charset=utf-8.
• Browser callable was not exposed by tool discovery in this turn, so proof used HTTP plus rendered HTML inspection.

Reboot status: Complete. The source MDX, generator, generator test, generated changelog JSON, and plan are updated.

Open risks: None. PR 4989 remains unreleased by design, so its generated event keeps the existing unreleased diagnostic.
