[finding] After the `jsonc` retag (PR #7473), 11 JSON fences in `skills/objectui/` still parse under no dialect (8 multi-document listings, 2 `...` elisions, 1 kept `json`) and 7 now-parseable `jsonc` fences carry no `os:check` marker

[os-litant]

Filed by the skills lane seat (session session_01LraLgQVGq8egUwfYZpbYt1) from the #7462 flight's report (PR #7473, comment 5522566624, out-of-scope items 1–3). One coherent content-edit follow-up on the same three files; the tag flight was tag-only by design. Unassigned, bare, for triage; landing surface governed skills/objectui/** (draft PR, human merge).

Measured by the flight at ec67429 with the repository's own parseJsonFence (scripts/check-skill-examples.mjs)

After the retag, 39 of the 40 remaining json fences parse strictly and 7 of the 16 jsonc fences parse under the JSONC dialect — 46 of 56. The residue:

shape	sites (fence opener line)	count
several top-level JSON documents listed in one fence	guides/schema-expressions.md 32, 170, 206, 447, 463, 479, 492; rules/protocol.md 177	8
... elision inside the JSON	rules/protocol.md 157, 166	2
total parsing under no dialect		10 (+ line 206 counted above stays json: a listing, not a dialect — 11 blocks by the card's parse-failure count)

And the coverage win left on the table: 7 retagged jsonc fences now parse and could carry the check-skill-examples opt-in marker (guides/schema-expressions.md 328, 355, 365, 374, 391; rules/protocol.md 187; rules/styling.md 170) — moving the enforced JSON population from 39 to 46. The flight proved the tag is load-bearing both ways (marker + jsonc → exit 0; marker + json → exit 1 naming rules/styling.md:171).

Scope

1. Split each multi-document listing into one fence per document (or one array where the prose reads as a set), keeping the prose between them minimal; retag the split fences by their content (json if strict, jsonc if a comment stays).
2. Replace the two ... elisions with a real value or a comment (// … is legal under jsonc; ... is not under any dialect).
3. Add the os:check marker line above the 7 parseable jsonc fences (and above any fence made parseable by steps 1–2), then run node scripts/check-skill-examples.mjs — the JSON phase must report the new count with 0 failed.
4. Report the fence census before/after (json / jsonc counts, parse-pass counts, marked counts) and the per-file byte/line arithmetic; there is no token ratchet over skills/** in objectui (measured by the flight), so the numbers are reported, not gated.

⛔ Not in scope: widening check-doc-fence-languages.mjs onto skills/ — measured and declined in PR #7473 (it reds on guides/project-setup.md:115, a genuine javascript postcss config, in the one UNKNOWN mode it never baselines, and its scan surface is pinned to check-doc-snippet-types's); pointing any doc gate at skills/ is the surface owner's decision per the UNGATED_DOCS note in check-doc-snippet-types.mjs.

Verified

• Dedup 2026-09-03T08:05Z (search_issues in objectui, 4 results): [finding] 17 of the 56 JSON fences in skills/objectui/ are tagged json while carrying // comments or ... elisions — jsonc is the honest tag, and no gate reaches fence language tags in skills/ #7462 (the tag flight, this card's parent), [finding] No gate holds skills/objectui/evals/*.json must_contain tokens to the guides they score — two hand sweeps (#7360, #7405) cleaned nine rows; the oracle (per-guide vs bundle-wide, whole-token vs substring) is undecided #7461 (the eval-token gate), finding(docs): three tsx fences in apps/console/docs are design-token lists that compile only as labelled statements — the snippet gate will be green about nothing once #6600 moves its roots #7426 (apps/console docs tsx fences — different surface), No gate reads inside a code fence in skills/objectui/ — 123 TypeScript fences and 63 JSON fences are checked by nothing #7359 (closed) — none carries these sites.
• Site list and counts are the flight's own measurements at ec67429 (PR docs(skills): tag the 16 comment-carrying JSON fences jsonc #7473 head); re-measure at claim.

ACCEPT — skills seat (session session_019RfFHiRCSs3JXLK4cwcfox), reviewer of record, 2026-09-04T06:09Z, verified against GitHub and a compare worktree at the PR head, not against the report.

PR #7608 @ 2ba20df — draft, base main (merge base 24e027e9), first line Fixes #7474, four files (guides/schema-expressions.md +51 lines, rules/protocol.md +12, rules/styling.md +1, scripts/check-skill-examples.mjs the MARKED_FLOOR json row 39 → 70 with the reason beside it), one commit, one footer, no model name, no control bytes, no changeset owed (the presence script decided; no label — this repository has no such mechanism). Local git merge-tree --write-tree origin/main (e62c44e) at 06:12Z: clean; mergeable_state reads behind, which the approver's landing absorbs.

What landed, re-verified at the head: the census the seat counted by grep matches the report — 41 json + 29 jsonc = 70 fences under skills/objectui/, 83 os:check markers (70 json/jsonc + the 13 ts), zero ... elisions left in rules/protocol.md; the eight multi-document listings are one fence per document, retagged by content (the :206 listing stays strict json, the rest jsonc); the two elisions became the real columns value the rule is about; 31 marker lines added — the 7 already-parseable jsonc fences plus the 24 fences the splits and elision fixes made parseable. The card's "11" is explained (the :206 listing counted twice in the title), and the re-measurement at the base reproduced the card's table exactly. The MARKED_FLOOR raise is the ADD direction the row's own docblock names; the ts row and the shrink-only property are untouched. The before leg was measured properly — the four files reverted to the pinned base on disk, the gate re-run (Marked: … 39 json (floor 39), JSON phase: 39 parsed, 0 failed), the restore proven by blob hashes — rather than quoted from the card.

Gates as reported at 2ba20df: check:skill-examples — JSON phase: 70 fence(s) parsed, 0 failed and Marked: 13 ts (floor 13), 70 json (floor 70); the gate's self-test 52 cases; the two vitest suites 120 tests; check:skills-paths, check:skill-eval-tokens, check:doc-fences, check:control-bytes (plus a manual scan of the four files), check:doc-types, check:doc-snippets (after building its own --build-filter), check:shell-escape-residue, the governed-guard self-test, pnpm lint 47/47 — all green; --test on the four paths: GOVERNED on 3 of 4. Report mcp_calls: 4 — within contract. The out-of-scope finding #7610 (parseJsonFence's docblock still says the corpus has zero jsonc fences — 16 since PR #7473, 29 now) is correctly left alone and triaged into pm:queue (XS, serial behind this PR).

CI at 06:09Z on 2ba20df: 29 check runs, 20 success + 3 skipped, 6 in progress; nothing red.

Terminal: governed (skills/objectui/**) ⇒ the PR stays draft and lands by an approver's hand; review requested from os-zhuang and hotlong over the REST reviewers endpoint (draft bit untouched), read back. The card keeps pm:dispatched until MERGED.
