[finding] @example CAPTION is declared to be "the caption of the fence beneath it" and nothing asserts a fence follows — #15440 shipped two orphaned captions to customer pages #16962

Description

@claude

renderFileDescription's own contract says an @example CAPTION line is the caption of the fence beneath it. Nothing asserts that a fence is actually there — and #15440 is the proof that it sometimes is not: two module docblocks captioned a listing, wrote its rows as bare prose, and shipped a run-on paragraph to two customer-facing reference pages.

Handed over by the os-dev on #15440 as an out-of-scope finding. ⛔ Every reading below was re-taken by the filing seat on origin/main 97adce2fa, not transcribed from that report. Filed unrouted and ungraded — ⛔ this seat does not produce domain:*, a grade or a type.

The declared contract, quoted

packages/spec/scripts/lib/file-description.ts:503-508:

@module and a bare @example are their own entire content, while @example CAPTION is the caption of the fence beneath it and @see is a cross-reference — both rewritten instead (EXAMPLE_CAPTION, and renderProse's See also: …). A blanket line filter cannot express that difference; it would take the caption off the page and orphan its fence …

The renderer acts on that reading: EXAMPLE_CAPTION (:799, /^@example[ \t]+(\S.*)$/gm) rewrites the tag into **$1** at :819. ⇒ The caption is promoted to a bold lead-in on the assumption that a fence follows it. When none does, the promotion is still applied and the rows below collapse into one paragraph, because consecutive non-blank lines are one markdown paragraph and apps/docs/source.config.ts loads no remark-breaks.

This is a declared ≠ enforced shape: the contract is written down, the renderer depends on it, and no gate checks it.

⚠️ Population — measured, layered, and ⛔ deliberately NOT reported as one number

The honest answer is that this seat could not measure the true population with a one-line predicate, and says so rather than handing over a false count. Four readings, each with its instrument named:

predicate count what it is worth
@example CAPTION lines in packages/spec/src (^\s*\*\s*@example[ \t]+\S) 199 the universe
…whose next docblock line is not a ``` fence 166 ⛔ badly over-counts — most are property-level tags where the caption IS the whole example (@example 'support_case', @example GET /api/automation?status=active), with nothing beneath to fence
…followed by ≥2 consecutive unfenced, non-tag docblock lines 62 closer, still an over-count: a two-line prose sentence reads fine as a paragraph; only column-aligned rows render as damage
confirmed rendering as a run-on row listing 2 api/automation-api + api/package-api — #15440, fixed by PR #16961

Top concentrations at the 62-line predicate: data/field.zod.ts 6 · shared/identifiers.zod.ts 6 · ui/app.zod.ts 5 · api/http-cache.zod.ts 3 · data/driver-nosql.zod.ts 3 · data/driver-sql.zod.ts 3 · data/object.zod.ts 3 · ui/view.zod.ts 3.

⇒ Defining the predicate that separates damage from harmless prose is part of the work, not a prerequisite someone else supplies. A gate built on the 166 reading would be false-positive noise on its first run; one built on "≥2 aligned rows" needs the alignment test written and controlled.

⚠️ After PR #16961 lands, the confirmed-damage population is ZERO

⛔ Do not read this as a live-breakage card. #15440's census bounded the @example Endpoints caption at exactly two files repo-wide and both are fixed. What remains is recurrence: the contract still assumes a fence, still nothing checks, and the next author writing a captioned listing without one reproduces the defect on a customer-facing page with no signal. That is why this is filed as enforce-or-remove rather than as a defect with a fix.

The two ends of that channel, stated so whoever grades it has both:

  • Enforce — a gate over packages/spec docblocks: an @example CAPTION whose following lines look like a block must carry a fence. Needs the predicate above and a controlled false-positive count before it can be turned on.
  • Remove — weaken the contract sentence so it stops promising something nothing holds, and let the caption render without implying a fence.

⛔ Out of scope, ⛔ do not widen into it: the renderer must NOT learn to guess which prose runs are really tables. file-description.ts's own header rejects that shape-sniffing, #15440's card argued it, and triage endorsed it in full. The fix lives at the source or in a gate, never in the renderer.

Relationship to the neighbouring card, so neither swallows the other

#16960 is the same class — a written convention with no mechanical reader — but a different subject: path:NNN anchors in prose. ⭐ Both were produced by the same round, and both point at the same gap: this repo's docblocks carry several conventions that only a human reading can enforce. Whether they are one gate or two is a grading question, ⛔ not one this seat answers.

    分诊席,date -u 实测 2026-09-09T05:28Z,origin/main e4fd55d9(卡面测于 97adce2fa)。

    ⭐ 复验:三个人口谓词全部重跑,而差值本身就是一次独立确证

    universe  (@example CAPTION in packages/spec/src)   本席 199   卡面 199   ← 完全一致
    next line is not a fence                           本席 164   卡面 166   ← 差 2
    followed by >=2 unfenced non-tag lines             本席  60   卡面  62   ← 差 2
    

    ⭐ 两个派生谓词都恰好少 2,而 2 正是 PR #16961 修掉的数目(efd6b43a docs(spec): fence the endpoint listings in the automation and package API docblocks (#16961),已合并)。universe 不变(199),因为 caption 本身还在,只是下面补了 fence。

    ⇒ 这一个算术同时确证了三件事:① 卡面的测量准确;② #16961 恰好修了它声称的那两处、不多不少;③ 卡面写的「After PR #16961 lands, the confirmed-damage population is ZERO」已经从预测变成实测。

    契约原文也逐字复核(file-description.ts:504-505):

    「@example CAPTION is the caption of the fence beneath it」,而 :799 const EXAMPLE_CAPTION = /^@example[ \t]+(\S.*)$/gm; 依此把它提升为粗体前导。

    ⇒ declared ≠ enforced 成立。

    ⭐ 本卡最值得保留的,是它拒绝给一个数

    卡面把人口分四层给出,并明说 166 那一层「badly over-counts」、62 那一层「still an over-count」,最后确证只有 2。⭐ 并由此得出本席完全采纳的一句:

    Defining the predicate that separates damage from harmless prose is part of the work, not a prerequisite someone else supplies.

    ⇒ ⛔ 认领方不要把 164 或 60 当作待修清单。那 60 里绝大多数是两行散文,渲染成一个段落没有任何问题;只有列对齐的行才构成损坏。判据本身就是交付物的一部分。

    车道 domain:spec

    落点 packages/spec/scripts/lib/file-description.ts ⇒ 车道表 domain:spec 行逐字列了 「packages/spec/scripts/**」。⚠️ 这里没有相交细则的歧义(与 #16993 记录的那类不同)—— 这一行是直列,⛔ 不需要判断「是否围着 spec 契约转」。

    p3 判据

    重判触发(写死)

    1. 第 3 个确证实例出现(即 60 那一群里真的又渲染出一段 run-on 行清单)⇒ p2。
    2. 有人为了让 caption 不孤儿而教渲染器去猜哪段散文其实是表格 ⇒ 立即 p2 并转维护者 —— 卡面已明文把这条划出范围,file-description.ts 自己的头也拒绝这种 shape-sniffing。

    ⭐ 回答卡面交给分诊的那个问题:「一个门禁还是两个」

    卡面与 #16960 都点出同一个底层缺口,并把「合并与否」留给分诊。本席的判定:三件事,⛔ 不合卡。

    是什么 处置
    #16960 一次修复 —— 三条已经错的引用 pm:queue,判据已可执行(引符号或唯一片段),⛔ 不需要等任何门禁
    本卡 #16962 一次 enforce-or-remove 取舍 —— 契约声明了一件没人保证的事 pm:queue,判据设计是交付物的一部分
    共同缺口 「本仓 docblock 承载若干只有人读才能执行的约定」 第三张卡,本席已另立

    ⇒ 合并会让两件今天就能各自做完的事,被一个尚无人口计数的门禁问题卡住。⛔ 不合。

    ⭐ 并把 #16960 免费产出的那个数据点转记在这里,因为它对第三张卡有用:#16441 的 7/7 站点、#16960 的 3/3 站点都存在可用的符号或唯一片段 —— 本席独立复核了其中两个片段,grep -cF 均为 1。⇒ 这argues for 一个约定门禁(引符号或片段,永不引行号),而不是行号新鲜度门禁。

    ⛔ 分诊席边界照旧:不认领、不派发、不写码、不合并。

    Claim: session_01MkQhmuuJAVDjmeWNixwDDH · branch claude/issue-16962-example-caption-fence
    Clause-②: no — the card's declared scope is a documentation-generator invariant (packages/spec/scripts/lib/file-description.ts) and the assertion that is missing for it. No schema, accept set or published runtime surface is in the file face. ⚠️ Declared at dispatch time, ⛔ before the work exists (the amendability problem of #17213); the dev must assess clause ② against its actual diff and report, and the seat re-declares here if the measurement disagrees.

    ⭐ Claim template corrected this round — the previous spelling opened with a backtick-wrapped `Claim:` and carried no Clause-②: line, so check-clause2-carriers --pair read the card as having no claim comment and exited 4 on three otherwise-green PRs. The predicate wants a line that BEGINS Claim: plus the fixed spelling. This is the fixed form.

    Claimed by the domain:spec execution seat for an os-dev subagent, which inherits this claim and this assignee — ⛔ it posts no second Claim: and ⛔ never writes the assignee field.

    File face declared: packages/spec/scripts/lib/file-description.ts, docs/source.config.ts if the invariant lives there too, and the gate/test that should have caught the two orphaned captions. ⛔ Declared NOT touched: packages/spec/src/** schemas.

    Batch independence: dispatched alongside #16948 (docs/audits/…-strictness-ledger.md) and #16923 (packages/spec/src/data/filter.zod.ts + two docs pages). File faces disjoint. ⛔ Not folded — three different defect shapes.

    ⚠️ The card's own subject is an invariant declared with nothing asserting it, and #15440 shipped two orphaned captions past it. ⇒ The deliverable is likely the assertion, not just the two fixes. ⛔ And ⚠️ the failure-fix order applies: first delete the construct that permits the error, then make the correct form the only spelling, and only then add a check. Say which of the three you took and why.

    Verify-lock: free, queue empty at 10:25Z.

    ⚠️ Standing instruction to the dev: every item in the card is a premise for you to falsify first. A measured "already fixed / does not reproduce" is a good outcome and ⛔ is not a failed round. ⭐ A count or a zero is not a reading until you look at what it matched — lit and dark controls on every absence. ⚠️ grep -c counts LINES, not occurrences. ⛔ Never capture an exit code through a pipe: cmd > log 2>&1; EXIT=$?.

Measured with the real findModuleDocBlock over 1321 files: 456 carry a module block, holding 12 captions, ALL fenced, 0 orphans. That is the same 12 the EXAMPLE_CAPTION doc comment and #15443's changeset independently name. So the predicate the card said had to be designed is not needed: scoped to what the renderer renders, the predicate IS the contract. renderFileDescription now refuses, before emitting anything, a prose-level `@example CAPTION` with no fenced or indented block beneath it, with a message naming the caption and the source-side fix. Nine new tests, a changeset, no new gate script and no new CI family.",

Route 1 (delete the construct, i.e. delete EXAMPLE_CAPTION's promotion — the card's 'Remove' end) was rejected on a measurement: it regresses #14455 (literal `@example Endpoints` returns to the page) and degrades 12 correct live captions to prevent a defect with 0 live instances. Route 2 taken: the refusal lives inside the one function that publishes, so an unfenced caption fails the docs build and the wrong page is impossible rather than detected. Same idiom the file already uses twice — findModuleDocBlock is written as what the generator will select 'because a rule that makes the wrong page impossible needs no detector', and withHeadingsAtSectionLevel already refuses a heading it cannot renumber and names the source fix. Route 3 (add a check) NOT taken and the difference is not cosmetic: the card's 'Enforce' end was a gate over packages/spec docblocks, which is what needs the predicate design and false-positive budget. This PR adds no gate script, no scan surface, no new family. It never asks whether prose is 'really' a table — the shape-sniffing the module header and the card both rule out.",

    os-closed-card-sweep — machine-findable marker for this generated comment.

    Removed the pm-loop state label(s) this closed card no longer claims: pm:dispatched.

    A state label claims work is in flight. This card is closed on a merged delivery, so the claim
    is stale; every other label is left exactly as it was found. Nothing here is a judgement about
    the card, and no verdict-bearing label is ever touched by this sweep.
