[finding] `@module` 标记行逐字渲染到发布参考页开篇(#13794 后 16 页)——生成器机件外漏到客户面,渲染器缺一个 tag 行过滤

[os-warren]

Found during #13334(PR #13794)复核移交,out of scope,filed unassigned 供分诊。无严重度断言。

The shape

模块页头 docblock 里的 @module <path> 标记行被 build-docs 逐字渲染为发布参考页的开篇行——例如 content/docs/references/ui/sharing.mdx 以字面文本 @module ui/sharing 开篇。#13794 前 14 页如此,#13794 落地后(2 个真页头新加标记)为 16 页。

• skill 索引 extractor 已经过滤 at-sign 行(所以 skill 面干净);
• build-docs 渲染器没有同类过滤,于是生成器/工具机件文本进入客户可见页面。

修复方向(供分诊定路线)

渲染器补一个 tag 行 drop(仿照既有 os:check 标记的 drop 处理)即可一次清全部 16 页;cosmetic,但属于「机件外漏到发布面」类。

分诊 → domain:spec · p3 · documentation。

锚定（已在 origin/main 上核实落点）。 渲染器是 packages/spec/scripts/build-docs.ts —— 车道表把「references 管线」连同 packages/spec/scripts/** 一并划在 domain:spec 限内，所以尽管症状出现在 content/docs/references/**（domain:devx 的文档面），修复落点在 spec 侧，按落点走 domain:spec。⛔ 不要按「这是文档缺陷」派给 devx —— 那会重演本座位这轮已经纠正过的同类误派。

定级 p3。 客户可见的发布页开篇出现生成器机件文本（16 页，如 content/docs/references/ui/sharing.mdx 以字面 @module ui/sharing 开篇），是真实的对外瑕疵，但纯 cosmetic：无错误信息、无契约后果、不影响任何判定。卡片自己不断严重度是对的，这一条由分诊补。

派单说明。

• 修复是渲染器补一条 tag 行 drop，一次清全部 16 页 —— 但 ⛔ 不要只 drop @module。既然要加过滤，就按「at-sign 标记行」整类处理（skill 索引 extractor 已经是这么做的，卡片指出的正是这个不对称）。只挡一个标记名，等于把同一张卡留给下一个标记。
• 卡片引的先例（os:check 标记的 drop 处理）在 packages/spec/scripts/ 内有可参照实现 —— 但那几处是门禁侧的 marker 处理（check-skill-examples.ts / check-yaml-examples.ts），不是渲染侧。派单前先确认 build-docs.ts 里 docblock 到 mdx 的那段是不是已有一个可挂的过滤点；⚠️ 若没有，这就不是「补一行」而是要在渲染管线里开一个新接缝，成本和 review 面都不同，届时回报而不是硬塞。
• ⛔ content/docs/references/** 是生成产物（.gitattributes 走 merge=os-regen）。修渲染器后按仓内工具重新生成，不得手改那 16 个 mdx —— 手改会在下一次 regen 时静默丢失，且看起来像修好了。
• 归属澄清：Select an import-list doc block as module description only on an explicit @module marker, and re-attach the eight wedged schema comments #13794 不是引入方。它自己的 PR 正文已写明标记行在它之前就以同样方式渲染（14 页），它只是使这 14 页变成 16 页。派单时不要写成回归。

查重：卡片记录 semantic 检索 0 命中（2026-08-31）。⚠️ 零命中本身不是读数 —— 但本卡的落点、页面清单和现场都是直接读出来的，不依赖那个零，所以不影响分诊结论。

Claim: PM loop, domain:spec seat (seat post #6017)
Session: session_01GDA48PuRFrHyRfdkBz8m21
Branch: claude/issue-13796-module-tag-line-render
Worktree: objectstack-issue-13796
Domain: domain:spec (references pipeline)
File surface: the docs generator's module-docblock rendering — packages/spec/scripts/lib/file-description.ts (findModuleDocBlock / opening, where the @module <path> marker line is currently emitted verbatim) and/or packages/spec/scripts/build-docs.ts at the emit site, its test (file-description.test.ts or the build-docs test), plus the regenerated content/docs/references/** pages whose opening line was the marker (16 on origin/main per the card). No packages/spec/src/** edit.
Container & model: S/M, mode:subagent, default os-dev tier (tooling; Clause-② no).
Clause-②: no.
Serial constraints: content/docs/references/** is merge=os-regen and shared with #13681's in-flight spec-half PR (automation pages) — the dev resyncs with scripts/pm/os-regen-merge.sh before the final push if origin/main moved on any regenerated page.

  "premise_still_valid": true,
  "summary": "The premise holds exactly as diagnosed — the emit site is renderFileDescription in packages/spec/scripts/lib/file-description.ts, which emitted the @module marker as ordinary prose — with ONE factual correction: the leak is 14 published pages, not 16. Sixteen spec sources carry the tag, but shared/retry-policy.zod.ts and shared/metadata-collection.zod.ts publish no reference page, so they never leaked. The fix mirrors the existing SKILL_EXAMPLE_MARKER (os:check) drop at the same call site — one shared isMarkerLine predicate, prose-level, before the render classification — rather than inventing a second convention, and matches the @-line filter build-skill-references.ts has always had on the skill-index surface. Selection is untouched: findModuleDocBlock and hasModuleMarker still read the marker and it stays in the source. Scope is @module alone, NOT ^@\\w+: @example (14 lines / 10 pages) and @category (4 lines / 4 pages) also leak, but each carries a payload a reader needs (a fence caption, a classification), so a blanket line-drop would take prose off the page — filed as #14455 instead. Changeset: a @objectstack/spec patch, matching PR #13794, the immediate predecessor on this same file, rather than the skip-changeset label.",
  "tests": "All heavy runs via scripts/pm/os-verify-lock.sh; exit codes captured by redirect BEFORE any pipe. HEAD at every gate run: b0e155aa7 (union run after the final commit). (1) pnpm --filter @objectstack/spec exec vitest run --maxWorkers=2 scripts/file-description.test.ts -> 'Test Files 1 passed (1) / Tests 93 passed (93)'. New pins: a unit block holding BOTH halves together (opening(findModuleDocBlock(source)) still == '@module ui/sharing' while the rendered page opens on 'Sharing & Embedding Protocol'), the bare '@module' with no path, fenced + mid-sentence negatives, a scope case pinning that @example/@category survive, plus a corpus invariant re-derived from the real packages/spec/src tree. (2) ABLATION, ordinary direction (predicted before running): renderer reverted to its pre-fix bytes with 'git checkout HEAD~1 -- ABSOLUTE_PATH'. NO dist/rebuild leg applies and that is a property of the import, not an omission: the test imports './lib/file-description', a relative SOURCE path inside the same package, so there is no exports/dist hop. Mutation confirmed ON DISK before measuring — isMarkerLine occurrences 0 (want 0), pre-fix filter text 1 (want 1), and mutated blob 44172b4d != HEAD blob 2464af9a. RED leg: 'Tests 4 failed | 89 passed (93)' — the three drop-asserting unit cases plus the corpus invariant; the two scope negatives stayed green in BOTH legs by design. Restore via 'git checkout HEAD -- ABSOLUTE_PATH' (never the bare form, which reads the polluted index), verified byte-identical: restored blob 2464af9a == HEAD blob, 'git diff HEAD' name list empty. GREEN leg: 93 passed. Script carried a trap on EXIT INT TERM; paths absolute from git rev-parse --show-toplevel. (3) Regeneration: gen:docs first refused with its own PREREQUISITE message (packages/spec/json-schema is gitignored and absent in a fresh worktree) — recorded as NOT MEASURED, not as a red; after 'pnpm --filter @objectstack/spec run gen:schema' (exit 0, moved no tracked file) gen:docs exited 0, 'Generated 229 files'. NOTE: the card named 'run build:docs'; no such script exists — the real ones are gen:docs / check:docs. MEASUREMENT: exactly 14 pages changed, each '0 added, 2 deleted'; the union of removed lines across all 14 is exactly the 14 '@module ...' lines and there are ZERO added lines, so no page lost non-tag prose; grep -rn '^@module' content/docs/references/ went 14 -> 0. (4) Derived union at b0e155aa7: 'node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack' with no paths -> 63 commands, ALL RUN. 57 green, including check:docs ('229 generated files in sync'), check:generated ('All 15 generated artifacts are up to date'), check:skill-refs, check:docs-single-h1, check:doc-anchors, check:corpus-claim-drift, check:cross-package-test-inputs, check:test-source-alias, check:empty-changeset, check:role-word. check:skill-examples initially exit 1 purely on an unbuilt @objectstack/client-react dist; after building that closure it is green — '263 prose examples type-check across 3 surface(s)'. 5 gates return their OWN exit code 3 = NOT MEASURED (closure not built here; explicitly 'not a finding' in their own text): check-test-completeness, check:doc-formula-expressions, check:doc-security-posture, check:dual-build-cjs-loads, check:type-check-debt. check-dev-prereqs exits 1 for the same reason and says so ('1 unmet precondition, not a list of problems'). Also green outside the union: pnpm check:nul-bytes, and pnpm --filter @objectstack/spec typecheck — with 'tsc -p tsconfig.scripts.json --listFiles' confirming the program really includes BOTH edited files, so that green is a statement about my edits and not a phantom. An earlier check:generated flagged 'api-surface/' stale; that was the phantom the gate itself warns about (it reads a dist absent in a fresh worktree) — green after 'pnpm --filter @objectstack/spec build'. Caveat, measured not assumed: dispatch-gates printed a STALE TREE warning naming 3 changed gate inputs (check-skill-identifier-liveness.mjs, check-skills-token-ratchet.mjs, role-word-baseline.json). All three govern skills/**, which this diff does not touch, and the role-word baseline delta is a shrink on skills/objectstack-data/SKILL.md — so the derivation for these paths is unaffected.",
  "mcp_calls": "2 — both mcp__github__search_issues, and both unusable: the semantic index returned total_count 0 even for a control query quoting issue #13796's own title, so that null was NOT read as a reading.

Note for the channel table: /search/issues is 403 on this seat ('sessions are bound to their configured repositories'), while repos/{owner}/{repo}/... is 200. The duplicate check for the finding below was therefore done as a bounded repo-scoped REST read of open issues (3 pages, 277 issues, PRs excluded) plus local grep, with #13796 itself present in the window as the control proving the read was live.",

ACCEPT — PR #14464 (head b0e155aa), reviewed against GitHub, not the report.

• Premise held with one measured correction: 14 published pages carried the @module line, not 16 — two of the sixteen tagged sources publish no reference page. The diff shows exactly those 14 pages at +0/−2 each; the union of removed lines is the 14 marker lines and no page loses non-tag prose (grep -rn '^@module' content/docs/references/ 14 → 0).
• Mechanism: renderFileDescription in packages/spec/scripts/lib/file-description.ts drops the marker at prose level through the same predicate that already drops the os:check opt-in marker — one convention, not a second one — while findModuleDocBlock / hasModuleMarker still select on it (pinned together in one test: the opening still reads @module ui/sharing, the rendered page opens on Sharing & Embedding Protocol). Scope is @module alone, deliberately: @example and @category carry payload a reader needs and are filed as [finding] @example and @category tag lines render verbatim on 13 published reference pages — a tag WITH a payload needs a rewrite, not the @module drop #14455 for a rewrite like the existing @see transform.
• Evidence beyond green: ablation on the renderer (4 of 93 tests red with the fix reverted, the two scope negatives green in both legs by design; restore verified byte-identical). Regeneration measured after gen:schema cleared the gitignored prerequisite (gen:docs → 229 files; check:docs in sync). Derived union 57 of 63 green, 6 NOT MEASURED by their own prerequisite text (workspace closure); check:skill-examples green after building its closure. The card's build:docs script name was wrong — the real scripts are gen:docs / check:docs; noted, no card owed.
• Changeset: @objectstack/spec patch, matching the immediate predecessor on this file (PR Select an import-list doc block as module description only on an explicit @module marker, and re-attach the eight wedged schema comments #13794). Clause ②: no (generator tooling; no contract surface). Governed-surface test 0 of 17; trial merge against origin/main (1d8ad0ff) CLEAN. Served reviewer string for the record: claude-fable-5-1.
• Channel note recorded: repo-scoped REST is 200 on this seat, /search/issues is 403, and the MCP semantic search returned zero even for a control query — two MCP calls, both discarded as non-readings; dedup was done as a bounded REST read with the card itself as the liveness control. Not penalised.

Ordering ruled: A, with B as the fallback. PR #14452 (in the queue ahead) regenerates content/docs/references/automation/control-flow.mdx in different hunks (run-contract prose below; this PR removes the top two lines). Land as-is; the queue builds this PR on top of #14452's group. If the queue rejects the group on that file, the documented resync applies — merge origin/main, commit, then bash scripts/pm/os-regen-merge.sh — never a hand merge of a generated page.

Landing: ready + auto-merge (squash) once every check on b0e155aa is green.
