content loss autoreview fixes

Objective: Fix accepted P1/P2 content-loss findings in the current content/** docs diff and rerun focused autoreview until it reports no accepted/actionable critical or major docs-loss findings.

Goal plan: docs/plans/2026-05-31-content-loss-autoreview-fixes.md

Completion threshold:

• Accepted content-loss findings are fixed or reverted to the previous detailed docs.
• Broken ComponentSource, anchors, snippets, and API references introduced by the docs diff are fixed.
• pnpm --filter www build:source passes.
• Focused autoreview --mode local for content/** reports clean.

Verification surface:

• pnpm --filter www build:source
• .agents/skills/autoreview/scripts/autoreview --mode local --prompt "<focused content-loss review>"
• Targeted rg checks for restored anchors, ComponentSource src, shouldMergeNodes, and fixed HTML/Markdown snippets.

Constraints:

• Keep the user's requested revert of the docs-check fallback parser.
• Do not stage, commit, push, or create a PR.
• Do not reintroduce deleted API/setup/reference docs as summaries when restore from HEAD is safer.
• Treat broken docs anchors and invalid registry source names as actionable content loss.

Boundaries:

• Source of truth: current worktree, current content/**, registry definitions in apps/www/src/registry/**, and render support in apps/www/src/lib/rehype-component.ts.
• Allowed edit scope: docs content and direct docs render support needed to make the docs valid.
• Browser surface: not required; this was a static content-loss/autoreview gate.
• Tracker sync: none.
• Non-goals: unrelated docs rewrite quality, unrelated script fixes, staging/commit/PR.

Blocked condition:

• The only non-content blocker is pnpm --filter www check:docs expecting .source/index.ts after the user-requested fallback-parser revert. That checker fix is owned by another thread, so this goal does not re-add the fallback.

Work Checklist:

• Objective includes outcome, completion threshold, verification surface, constraints, boundaries, and blocked condition.
• Docs lane classified as broad docs-loss review across API reference, plugin/feature, serialization/conversion, install, and example docs.
• Target docs and affected sibling docs were inspected before patching accepted findings.
• Docs style doctrine was respected for current-state wording where new prose was added.
• Documented behavior or API was verified against current source where snippets/options were changed.
• Ownership map recorded through source paths and registry/render support files.
• Fastest corrective path was used: restore high-risk reference docs from HEAD, patch narrow remaining defects.
• Opening prose in touched docs avoids generic fluff where edited.
• Named APIs, options, transforms, components, imports, routes, and package specifiers are exact and current where patched.
• Plugin docs with major reference loss were restored instead of summarized.
• Serialization docs restore detailed HTML/Markdown contracts and correct unsupported raw-HTML guidance.
• API reference docs restore exact contracts such as Slate API details and core options.
• Demos/previews use real registry entries or supported ComponentSource src.
• Links target real pages and anchors.
• Anti-slop audit passed through focused autoreview clean result.
• Workspace authority recorded with cwd /Users/zbeyens/git/plate.
• Autoreview target selected and run for non-trivial docs work.

Completion Gates:

Gate	Applies	Required action	Evidence
Named verification threshold	yes	Run source generation and focused autoreview	pnpm --filter www build:source passed; final autoreview clean.

Source-backed claim audit	yes	Verify changed API/source claims	HTML deserialize shape, Markdown options, and ComponentSource src support checked against source.
Ownership map verified	yes	Confirm package/layer ownership	Registry entries and rehype-component.ts inspected.
MDX/content parser	yes	Run source generation	pnpm --filter www build:source passed.
Links/routes/previews verified	yes	Check accepted broken anchors/source names	Autoreview clean; targeted rg showed valid source blocks and anchor.
Plugin page specifics	yes	Restore plugin reference pages with major loss	Link, media, AI, Yjs, table, and other high-risk docs restored or corrected.
Browser/render surface changed	no	Static source generation covers this fix	Browser proof not required for content-loss objective.
Package/API behavior changed	no	Record N/A	Docs/render hydration only; no package API behavior changed.
Agent rules or skills changed	no	Record N/A	No agent rules or skills changed in this goal closeout.
Autoreview for non-trivial docs changes	yes	Run focused review until clean	Final autoreview: no accepted/actionable findings.
Final lint	no	Record N/A	User asked content-loss fix; no lint gate needed beyond source generation/autoreview.
Goal plan complete	yes	Run node .agents/skills/autogoal/scripts/check-complete.mjs docs/plans/2026-05-31-content-loss-autoreview-fixes.md	To run after this update.

Findings:

• Initial review found major content loss in Slate API reference, changelog, Next.js snippets, table docs, Markdown security guidance, core options, HTML customization docs, Markdown rules, link/media/AI/Yjs docs, and invalid example source blocks.
• Accepted findings were fixed by restoring risky reference-heavy docs from HEAD and patching precise defects that remained.

Decisions and tradeoffs:

• Restored high-deletion and net-deletion docs from HEAD instead of trying to preserve lossy summaries.
• Kept the user's requested revert of the docs-check fallback parser, even though check:docs still fails in this checkout without the other-thread fix.
• Added ComponentSource src hydration support because the docs component already exposed the prop and the examples needed secondary registry files.

Implementation notes:

• Restored detailed Slate, table, changelog, core, HTML, Markdown, link, media, AI, Yjs, and other high-risk docs where autoreview or deletion counts showed reference loss.
• Added shouldMergeNodes API reference and fixed editing-behavior/table anchors.
• Fixed Next.js client snippets, HTML deserialize call shape, Markdown raw-HTML guidance, Markdown API options, and example value source rendering.

Review fixes:

• Final accepted finding fixed by switching invalid ComponentSource name values to ComponentSource src and wiring src in rehype-component.ts.

Error attempts:

Error / failed attempt	Count	Next different move	Resolution
pnpm --filter www check:docs failed after fallback revert because .source/index.ts is absent	1	Do not re-add fallback; rely on other-thread checker fix and run build:source plus autoreview here	User requested fallback revert; build:source and final autoreview passed

Verification evidence:

• pnpm --filter www build:source passed after the ComponentSource src fix.
• Final focused autoreview --mode local exited 0 with: autoreview clean: no accepted/actionable findings reported.
• Targeted checks showed invalid value ComponentSource name usages removed and replaced with src.
• Targeted checks showed troubleshooting links /docs/plugin#advanced-plugin-configuration and editor-api#shouldmergenodes.
• pnpm --filter www check:docs remains outside this goal's green evidence after the user-requested fallback revert because the current checkout still lacks .source/index.ts.

Final handoff contract:

• PR line: no PR requested.
• Issue / tracker line: no tracker update requested.
• Confidence line: high for content-loss objective; final autoreview clean.
• Docs lane: broad content-loss repair.
• Source-backed claims: checked against source/registry/render support where modified.
• Content build / parser: pnpm --filter www build:source passed.
• Links / demos / previews: accepted broken cases fixed and reviewed clean.
• Browser check: N/A for static docs-loss gate.
• Outcome: accepted/actionable critical and major content-loss findings cleared.
• Caveat: full check:docs still needs the other-thread .source/index.ts fix in this checkout.
• Verified: final focused autoreview clean.

Final handoff / sync:

• PR: none.
• Issue / tracker: none.
• Browser proof: none required.
• Caveats: check:docs caveat above.

Timeline:

• 2026-05-31T20:01:26.168Z Docs goal plan created.
• 2026-06-01: Reverted checker fallback per user request, fixed invalid ComponentSource value sources, ran build:source, and got focused autoreview clean.

Reboot status:

Question	Answer
Where am I?	Closeout
Where am I going?	Run autogoal completion checker, then mark goal complete if it passes
What is the goal?	Clear accepted/actionable critical or major content-loss findings in content/**
What have I learned?	Lossy summaries were the core risk; restores plus targeted fixes were safer
What have I done?	Fixed accepted findings, reverted requested fallback parser, and got clean autoreview

Open risks:

• Full pnpm --filter www check:docs is not green in this checkout until the separate .source/index.ts generator/checker fix is present.
