Docs review / update pass

A single, consistent standard for every .md under documentation/content/ (each file documents a pota export or a guide page). The pass is resumable and runs without subagents. Resume anchor lives in tools/ai-docs-review/progress.md, next to the helper scripts (all version-tracked, so they survive fresh checkouts and npm run clean). The scripts resolve the content tree relative to their own location, so they run from any cwd; point them at another content tree with CONTENT_DIR=… (docs-site project: DOCS_DIR=…).

How to start / resume (DO THIS FIRST)

1. If progress.md exists, this is a resume. Read it, jump to the first unchecked - [ ] box, and continue. Do NOT regenerate it (that wipes ticks). Trust the ticks — already-done files are done.
2. If it does not exist, create it (see progress.md below) and start from the top.

Resumability is the #1 invariant: a box is "done" ONLY when it is ticked in progress.md. A fresh session with zero prior context must be able to pick up from the first unchecked box. Tick the moment a file is verified+fixed.

Why synchronous, no subagents

Do the verification in the main loop, file by file. Do NOT fan out to background-Workflow/subagents for this: when a subagent hits the account session limit it reports success while silently leaving work half-done, and its file edits are hard to reconcile. The main loop + per-file ticks make interruption recovery trivial. (This overrides the usual "use a workflow" nudge for this task.)

Terminal output discipline — stay quiet

Spend tokens on the work, not on reports. While grinding through files:

• Default to silence or one terse line ("color done, 181/327"). Do not narrate every file, re-explain the plan, or re-list what's left every turn.
• The durable record is progress.md (ticks + notes) and the Flags for maintainer / Fixes applied sections — write findings THERE, not in long terminal recaps.
• Only surface prose to the terminal for: a genuine blocking question, a real bug worth the maintainer's eyes right now, or a brief end-of-session checkpoint. Otherwise let progress.md speak.
• Never pad responses with status tables the user can read in progress.md.

progress.md (the resume anchor)

Generate with scripts/gen_progress.mjs (regenerates the checklist skeleton from the current file tree — run only when the content tree changes; it does NOT preserve ticks). It contains:

• How-to-resume + this spec inline (so resumption needs no other context).
• Global checks G1–G7 (below), each its own checkbox.
• Per-file checklist grouped by source module — every .md as a - [ ]. Grouping by source lets you read each src/ module once and verify all its pages together.
• Fixes applied and Flags for maintainer sections (append-only logs).

Tick with scripts/tick.mjs (bookkeeping only — content edits still go through Edit/Write so the maintainer reviews real diffs):

node tools/ai-docs-review/tick.mjs \
  "path.md::✓ clean (why)" \
  "path2.md::✓ fixed: <what>" \
  "path3.md::⚑ flagged: <one-line>" \
  "fix::<bullet for Fixes applied>" \
  "flag::<bullet for Flags for maintainer>"

Use absolute paths to the script (the shell cwd is not guaranteed). Avoid embedded double-quotes in args (they break shell parsing — the script will report NO MATCH).

Per-file verification (ACCURACY IS #1)

For each page, read its source module first (the group header names it), then confirm and fix in place:

1. Format / frontmatter — exactly: title (KEEP verbatim — referenced by topics.js; NEVER change it), subpath, topic, desc (required, one short plain sentence ≤120 chars). kind: component ONLY on capitalized-component pages; no other kind. No bucket/exports/tagline. Body order: # H1 → 1–3¶ lede (first sentence mirrors desc; link related exports) → ## Arguments / ## Attributes table (types match the REAL signature; add **Returns:** when meaningful) or ## Exports link-list for overview pages → optional explanatory ## Sections → ## Examples.
2. Example one-liners — every ### example under ## Examples opens with a leading one-line prose description (a clear, simple statement of what it shows) BEFORE the code fence. A ## Section that merely mirrors an example is forbidden — fold it into the example's one-liner and delete the stray heading.
3. Accurate desc + prose — every statement, argument name/type, return value, option, and behavior MATCHES the actual code. Never document a method/option that doesn't exist; never omit a load-bearing one; never invent behavior.
4. Idiomatic examples (pota conventions):
   • native on:click / component onClick; class= not className; element ref is use:ref={…} (bare ref= does NOT capture the node).
   • reactive child/prop is the READER fn {count.read} / {() => …} / <Show when={flag.read}>; never {signal} as a child; {signal.read()} only for a deliberate static snapshot.
   • signal API .read() / .write(v) (no prev arg) / .update(prev => next).
   • inline style keys are KEBAB-CASE.
   • use/* plugins via use:ref={factory(opts)} (compose use:ref={[a(), b()]}).
   • prefer derivation (memo/derived/resolve) over effects.
   • runnable examples are SELF-CONTAINED ending in render(App) (a non-UI illustration for an inherently non-visual export may be console-only).
   • relative imports include the file extension; tabs, single quotes, no semicolons.

Global checks (G1–G7)

• G1 — Format/example validator (scripts/validate.mjs): mechanical frontmatter + example-one-liner check. Baseline must be N/N; RERUN after edits to confirm no regressions.
• G2 — Completeness: every export from package.json "exports"
  • src/exports.js + each module has ≥1 page; complex use/* modules expand each export into a folder. scripts/completeness.mjs is a coarse net with known false positives (single-export modules documented by their overview file; Emitter-destructured on*/use*; comment artifacts) — the authoritative check is reading each source during the per-file pass. Create a page for any genuine gap.
• G3 — Overview/index pages: each folder index (use/<mod>.md, etc.) has an ## Exports link-list covering EVERY sub-page in its folder.
• G4 — topics.js (projects/docs/tools/topics.js, checked by topics-check.mjs): comprehensive of all APIs; no More catch-all section; closely-related APIs grouped tightly; sensible duplication allowed (a page may appear in more than one topic — adjust buildManifest's claim logic if it forbids that). Every page reachable from a topic. (Titles are LOAD-BEARING — topics.js matches pages by id/title/export; never rename a page title to fit.)
• G5 — Build: npm run build (vite) green; spot-check a few rendered pages.
• G6 — Internal-link integrity (scripts/links.mjs): every markdown ](/…) link resolves to a real page route. The router matches location.pathname() EXACTLY against '/' + <relpath-without-.md> (NO aliasing — src/index.jsx). RERUN until 0 broken.
• G7 — Example type-check (scripts/typecheck.mjs): every ## Examples jsx/tsx fence type-checks against pota's types — an OFFLINE replica of the live-playground checker (same compiler options; needs generated/docs/types.json from npm run build:generate). Catches regressions the runnable-example pass can introduce (=> in JSX text → TS1382; a JSX.Element-typed value in a template literal → TS2731; wrong arg types). Optional path-substring args filter the run. A small in-script ALLOW map carries intentional, page-documented errors (e.g. store/readonly's rejected write); a handful of fences error inherently (multi-file routing load, updateBlacklist/toHTML/pasteText typing) — see the Flags. RERUN after edits; only known/allowlisted errors may remain.

Flags vs fixes (don't guess)

• Fix in place anything you can confirm wrong from source (signatures, behavior, broken links, non-idiomatic code, format). Log substantive fixes to Fixes applied.
• Flag anything genuinely ambiguous — a behavior you can't confirm from source, or a judgment call on which example/wording is "right". Do NOT guess: write it to the Flags for maintainer section of progress.md (via flag::…) with the diagnosis and a suggested fix, tick the file ⚑ flagged, and move on. Never delete a flag without resolving it.

Hard constraints

• NEVER change a title or subpath frontmatter value.
• Do NOT touch pota src/, the content parser, or the runtime — only the docs .md files and topics.js.
• NEVER commit or push; the maintainer reviews diffs in their own git client. (topics.js and the docs-site app live in a nested git repo at projects/docs — changes there don't show in the parent repo's status; the content and progress.md are in the parent repo.)

Helper scripts (in tools/ai-docs-review/)

One per global check — validate (G1), completeness (G2), overview (G3), topics-check (G4), links (G6), typecheck (G7) — plus tick (tick boxes / append fix+flag bullets), gen_progress (regenerate the skeleton), and shared _paths.mjs (resolves REPO/DOCS/CONTENT/PROGRESS/TOPICS, honors DOCS_DIR). Version-tracked; read the dir. Recreate any that goes missing — they are small and deterministic, contracts described above.
