   Claim: skills lane seat — pm:queue → pm:dispatched and the assignee set in the same write. Dispatching one os-dev flight.
   Session: https://claude.ai/code/session_01LraLgQVGq8egUwfYZpbYt1
   Branch: claude/issue-7406-page-builder-section-type
   Clause-②: yes — the guide will state which structural types the component registry registers; a falsifiable published-surface claim ⇒ needs:contract-review on the PR, reviewed in-seat at CONTRACT_REVIEW_TIER before any human review request.

   Disposition chosen by the seat in-lane: teach it (the card's option 1) — section is registered (packages/components/src/renderers/layout/containers.tsx:988) and authored in the catalogue, so the closed-set sentence is simply false; one row in the layout-primitive table plus the corrected count, paid in the same file under the programme's shrink-or-neutral rule (measured ceil(utf8/4) before and after). ⛔ No new section. Collision check: PR #7408 (#7360, at the terminal) touches guides/plugin-development.md and five evals/*.json files, not guides/page-builder.md — disjoint. The section eval row #7408 re-pointed to card stays as landed; #7405's rows are not this card's. Governed skills/objectui/** ⇒ draft PR, first line Fixes #7406.

     "summary": "The card's actionable premise held and the fix landed: `guides/page-builder.md` claimed 'Five registered types do all the structural work' while the token `section` occurred 0 times in the guide (verified at base 24d4a21). Added one `section` row in the table's own shape and replaced the closed-set sentence with a recommendation. IMPORTANT CORRECTION the card and dispatch both got wrong: the registration behind the authorable `section` is NOT containers.tsx:988 — that call passes `skipFallback: true` with `namespace: 'page'`, so it registers ONLY `page:section` and never claims the bare key; the bare `section` the catalogue authors comes from the semantic-tag factory at packages/components/src/renderers/layout/semantic.tsx:46 (`ui:section`, `SemanticSection`), measured at runtime as bare_is_page=false. Reading the row's props from containers.tsx as instructed would have published a false row (`space-y-4` and a `children` slot input belong to a key the guide does not teach). I also took the reword rather than a corrected count of six, because the same factory registers `aside`, `main`, `nav` and `article` on identical terms, so any closed-set number is falsifiable. Budget: ceil(utf8/4) 3062 before, 3062 after — neutral, paid from two strict restatements of the table. Note one instruction conflict: the dispatch says 'no model identifiers in commit messages', while a harness system-reminder mandates a Co-Authored-By attribution line that contains one and declares it replaces earlier attribution guidance; I followed the system-reminder and am flagging it rather than choosing silently.",

Derived beyond the dispatch list: check-doc-fence-languages.mjs exit 0 ('every TypeScript block in 224 document(s) is fenced ts/tsx/typescript') and check-doc-component-types.mjs exit 0 ('Every documented component type is registered'), the latter then measured OUT of scope (it walks content/docs and nothing else, :214). check-doc-snippet-types.mjs exit 2 = 'PRECONDITION NOT MET — The snippet program was NOT run' on an unbuilt worktree; read as NOT MEASURED, not red, and not owed: its declared surface is content/docs/** plus packages/*/README.md (:301), which excludes skills/**. Vitest, from the REPO ROOT (the repo hard-blocks package-dir vitest as a false-green trap) and under the shared lock with slot objectui-7406: doc-version-claims, check-skills-paths, skill-guide-provider-envelope, skill-guide-data-table-binding, skill-guide-permission-config -> 'Test Files 5 passed (5)', 'Tests 105 passed (105)', lock VERDICT command-exit 0. Suite selection was derived, not assumed: git grep -l 'page-builder.md' scripts packages returns nothing, so the skill-guide-* family was enumerated by filename and run whole. eslint narrowing MEASURED with all three pieces: (1) population read from eslint.config.js itself — every files entry is .ts/.tsx (lines 28,176,196,218,232,262), the lone markdown|mdx match is a comment on line 22; (2) count from --format json — errorCount 0 with eslint's own message 'File ignored because no matching configuration was supplied.', so the file is outside the linted population; (3) invariance — no markdown processor is configured and no .ts/.tsx file is touched, so this diff cannot move any other file's verdict. Runtime probe (a throwaway test against the real registry, removed before commit, tree verified clean): bare_type='ui:section', bare_display='SemanticSection', page_type='page:section', page_display='PageSectionRenderer', bare_is_ui=true, bare_is_page=false, bare_inputs=[{name:'className',type:'string'}]. No ablation was performed — nothing here required one.",

The dedup search found it (the same search returned #7406 itself, so it was a live read, not an empty-result false negative). `section` now joins `box` in exactly that gap: the guide's layout table teaches two bare types that are absent from the curated ADR-0080 PUBLIC_BLOCKS contract, while `page:section` — which IS in the contract — is taught nowhere. Same finding class, same file, so it belongs on #6879 rather than in a second card."

   Seat review — ACCEPT; contract review (clause ②) — PASS

   PR #7416, head 42eea12, Fixes #7406. Verified on the branch head and at source, not from the PR body:

   • One file, +8/−10: one section row in the layout-primitive table (renders a semantic section; no props beyond a verbatim className, like box; reach for it as box with an outline landmark) and the closed-set sentence reworded into a recommendation. Token-neutral by the programme's rule: 3,062 → 3,062 (ceil(utf8/4), +3 bytes), paid by two strict restatements of the table (the stack sentence and the box paragraph's enumeration), both checked as restatements; the deletions the dev rejected as load-bearing were correctly kept.
   • Clause ② at CONTRACT_REVIEW_TIER (the served model read via get_session equals the constant): the row's claims are true at source, and the card's own premise was wrong in a way the dev caught. The authorable bare section is registered by the semantic-tag factory packages/components/src/renderers/layout/semantic.tsx:46 (namespace: 'ui', no skipFallback, so Registry.register writes the bare-name fallback — packages/core/src/registry/Registry.ts:468); it renders the tag with className passed through and children/body rendered (semantic.tsx:31-40), single declared input className (:70-72). containers.tsx:988 — the site the card and the dispatch named — registers page:section with skipFallback: true and never claims the bare key; reading the row's defaults from there would have published a false row (space-y-4, a children slot). The dev's runtime probe (bare_type = ui:section, bare_is_page = false) agrees with the source reading. The reword over a corrected count is right: the same factory registers aside, main, nav and article as bare structural types, so any census is falsifiable. PASS ⇒ under the 2026-08-31 ruling the seat strips needs:contract-review from PR skills(objectui): page-builder teaches section, and stops claiming a closed set of five #7416 (the card never carried it).
   • Gates at head, each by its own verdict line: check-skills-paths 88/89 (the row states no path); doc-links; control-bytes; shell-escape-residue 5/5 roots; changeset-presence (none owed); governed-queue-guard --test → GOVERNED (exit 3, the correct verdict); doc-fence-languages; vitest 105/105 across the five skill-guide-* / doc-claim suites, run from the repo root under the shared lock; eslint narrowing measured from the config. check-doc-snippet-types NOT MEASURED locally and not owed (its surface is content/docs/** + package READMEs by its own :301); CI runs it and the README export check regardless — 24 of 26 checks green at 23:5xZ, those two still running and outside this diff's surface by their own declared scopes.
   • The dev's attribution note: the harness Co-Authored-By trailer is the accepted attribution (ruling recorded on #13680), so nothing to change. Its dedup finding (section and box taught by the guide yet absent from the ADR-0080 PUBLIC_BLOCKS Tier B, while page:section is in the contract and taught nowhere) already belongs to open finding(core/contract): the newly minted box type is not in PUBLIC_BLOCKS Tier B, so the curated AI-authoring vocabulary omits a type 27 catalog exemplars now teach #6879 — recorded there by the dev, no new card.

   Landing: governed skills/objectui/** ⇒ PR stays draft; review requested from os-zhuang + hotlong. At MERGED the seat strips pm:dispatched.
