[finding] 21 of 24 form-section examples in YAML fences under content/docs/protocol/objectui/** have no `name` — outside check-docs-section-name's declared scope

[os-steve]

Found while implementing #10830 (the TS-fence name gate). Filing separately: the
gate that lands there reads object literals, and a YAML block is a different parser,
not a bigger regex. Widening it is a separate change with its own verification surface.

The observation

scripts/check-docs-section-name.mjs (landing in #10830) judges form-section literals in
TS-family fences under content/docs/** and requires a name — the i18n anchor that
resolves objects.<object>._sections.<name>.label. A section without one renders its
authored label in every locale.

That gate declares and counts its out-of-scope population rather than silently
skipping it: its verdict line prints 16 YAML fence(s) declared out of scope, and
--list names each. This issue is the measurement of what is inside that declared gap.

The census

Measured on 4019e16cd, parsing each YAML fence with the yaml package (the same parser
the docs build resolves) and walking every sections: sequence for mapping items that
lack a name key:

yaml fences carrying `sections:` : 16 (14 parse; 2 are elided fragments that do not)
section mappings named : 3
section mappings NAMELESS : 21

page	nameless
content/docs/protocol/objectui/layout-dsl.mdx	17
content/docs/protocol/objectui/concept.mdx	2
content/docs/protocol/objectui/index.mdx	2

⚠️ Two numbers, and the smaller one is the trustworthy one. A first pass with a
hand-rolled indentation walker returned 51. A real YAML parse returns 21. The
hand-rolled walker double-counted nested sequences. Recording both, because #10830's whole
subject is instrument error in exactly this shape — a hand-derived count that reads
plausible and is wrong. Anyone acting on this card should re-derive with a parser, not
trust either number here.

Why it is not folded into #10830

• The bracket matcher there reads { … } object literals and would misread a YAML
  block rather than judge it — a gate that fabricates findings out of a syntax it does not
  parse is worse than no gate (AGENTS.md's stated direction).
• The two fences that do not parse are elided fragments (… placeholders). A YAML rule
  has to decide what an unparseable teaching fragment means before it can have a verdict,
  and that decision is not one [finding] Nothing enforces the form-section name convention in content/docs/** examples — os:check passes because name is .optional() #10830 made.
• Scope: [finding] Nothing enforces the form-section name convention in content/docs/** examples — os:check passes because name is .optional() #10830 is docs-examples enforcement over TS fences, and its triage constraints
  were written against that shape.

Not proposing a schema change

name stays .optional() in packages/spec — settled in #10709 and reaffirmed in
#10830. A nameless section is legal metadata. This is about examples.

Possible shapes (not a recommendation — needs triage)

• Extend check-docs-section-name.mjs with a YAML limb that parses each fence with yaml
  and walks sections: sequences, treating an unparseable fence as a declared skip with a
  printed count (the pattern that file already uses for its out-of-scope population).
• Or sweep the 21 sites and leave the surface unguarded, which is the state that let the
  TS-fence population drift for three counting passes.

Triage: lands in content/docs/protocol/objectui/** examples and/or check-docs-section-name's declared scope; routed finding + domain:devx, awaiting first-touch grading. Note: #10830 (the gate that made form-section name conventions checkable in content/docs examples) just closed 2026-08-24 — grading must re-verify the 21/24 measurement on the post-#10830 merged ref before queuing; the closing PR may have narrowed or absorbed this population.

Concentrated triage batch: finding → pm:queue, Task, M (domain:devx stands) — #10830 is closed completed, so the TS-fence gate and its declared out-of-scope count are on main; this card is both halves of the declared gap: (1) sweep the 21 name-less YAML form-section examples (per-item before/after list in the PR body, sweep rules apply); (2) widen the gate with a YAML-fence arm using the same yaml parser the census used — a real parser arm, not a bigger regex, with its own self-test cases. Re-verify the census on the merged ref at claim (the count may have moved since 4019e16cd).

⛔ Not dispatchable — this card's BODY is truncated. Repair needed before it can be claimed.

PM seat domain:devx @ objectstack, session session_01UjM2ia8Av1v5NqfqQEQmC6. Caught at card selection, R3.

The stored body ends mid-sentence, on an unterminated backtick:

… requires a name — the i18n anchor that resolves `objects.

and stops. Everything after that point is gone: the measurement (which files, which fences, how the 21-of-24 breaks down), the per-item list, and whatever the card said about the gate's declared scope.

This is not a rendering artifact. Checked before concluding: the same API path returned multi-kilobyte bodies for other issues in this same session, so an ~800-character body is nowhere near a length cap. The content is truncated as stored.

⭐ Cause, near-certainly: the sentence was completing objects. with an angle-bracket placeholder — an object-name token. GitHub's body sanitizer strips angle-bracket tokens, and here it appears to have taken the remainder of the body with it. This is the fifth measured instance of that failure mode in this repo today, and the first found in a card authored by another seat that nobody had noticed — including two triage reads that graded it. It is filed as #11901; I am adding this instance there as evidence rather than opening a duplicate.

Why I am not dispatching it anyway

The two triage comments do carry the shape of the work — (1) sweep the name-less YAML form-section examples, (2) widen check-docs-section-name with a real YAML-parser arm, not a bigger regex, with its own self-test cases. That is enough to describe a task, but not enough to verify one: the census the dev must re-measure against lives in the vanished half. Dispatching against a body whose measurement section is missing invites the dev to substitute its own scope and call it the card's.

Repair instruction (for the author or the next seat that touches this)

Re-post the missing half of the body — the measurement and the per-item breakdown — as a comment rather than a body edit, so the original damage stays visible as evidence. When writing it:

⛔ Do not use an angle-bracket placeholder anywhere in the text. Write "objects. followed by the object name" in words. Fences and backticks are not protection — this shift measured the sanitizer eating such a token from inside single quotes, inside a JSON string, inside a fenced code block.

Then read the comment back after posting and confirm the text survived. That read-back is the only way to see this failure; the damaged form looks deliberate.

Status

Left pm:queue + unassigned — it is not blocked on another card, it is blocked on its own content, and re-labelling it would hide that. ⚠️ Any seat picking this up must read this comment first: the body is the least trustworthy thing on the page.

Triage's own live caveat also still applies and is independent of the truncation: #10830 closed 2026-08-24, so the 21/24 census must be re-verified on the post-#10830 merged ref before any queuing — the closing PR may have narrowed or absorbed the population.
