finding(docs): 22 of 198 json-tagged fences under content/docs fail JSON.parse — and the one gate that reads them normalizes exactly those two shapes away

Path: P1 | 那条路第 1 步「写元数据」 | content/docs 下 198 个 json 围栏有 22 个过不了 JSON.parse,而唯一读它们的门禁正好把这两种形状归一化掉
分诊重测与定级:2026-09-20T15:58Z

Dedupe words: json fence not valid JSON · doc example fails JSON.parse · json-tagged fence comment · no gate asserts json fence validity · expression-carriage tolerance hides invalid json

Surfaced by the objectui#9989 dev while repairing one such fence. ⭐ Re-measured first-hand by the domain:ui#2 execution seat before filing (PM session session_018HrVaotisyhgmot9o2MLRq) — 立卡也要分「自量」与「转述」, and this is the 自量 half. ⛔ No priority:* and no type are written here: both are the triage seat's sole production. domain:ui is inherited from the in-flight parent objectui#9989 under the derivation exception, ⛔ not a routing decision.

The reading, taken by this seat on `origin/main`

A fence-walker over every .md / .mdx under content/docs, feeding each ```json body to JSON.parse:

json-tagged fences: 198
FAIL JSON.parse: 22

⭐ Control, same command, both directions — the same parser rejects {"a":1,} (Expecting property name enclosed in doub…) and accepts {"a":1}. ⇒ the 22 is a reading and the 176 is not a dark pass.

Concentration:

page	failing fences
`content/docs/guide/expressions.md`	9
`content/docs/guide/layout.md`	4
`content/docs/utilities/runner.mdx`	4
`content/docs/guide/schema-rendering.md`	2
`content/docs/guide/deployment.md`	1
`content/docs/plugins/index.md`	1
`content/docs/utilities/vscode-extension.mdx`	1

⚠️ One of schema-rendering.md's two is repaired by PR objectui#10086, which is landing — so ⭐ re-measure on origin/main when this card is taken; the figure above is anchored to a tree that PR changes.

Why a reader is harmed: the failure lands BEFORE the schema

A json-tagged fence is what an author copies. When it does not parse, the reader's editor or JSON.parse rejects it before the value ever reaches a schema, so the page's own subject — which keys are legal — never gets a chance to be right or wrong. The two shapes doing it are a JavaScript comment inside the fence (/* … */) and raw newlines inside a string.

⚠️ Why this is a triage call and ⛔ NOT a drive-by fix

Several of the 22 are deliberate. Elision markers and // Bad: counter-examples are doing a job: a counter-example that parses is a worse counter-example. ⇒ the deliverable is ⛔ not「make 22 go to 0」. Somebody has to decide:

which non-parsing spellings are declared (an elision convention, a counter-example convention) and how a reader tells them from a mistake;
whether any gate flips to blocking on the rest — ⭐ a gate-strength decision, which is on the human floor.

Measured by the #9989 dev, ⛔ NOT re-run by this seat: why no gate catches it

Recorded as 转述 and marked as such, because the taking dev should re-take it rather than trust this table:

gate	why it is silent here
`check:doc-snippets`	compiles `ts` / `tsx` / `typescript` only; its own header states a `json` fence is never compiled against anything
`check:doc-fences`	asks whether a TypeScript BODY sits under a non-TypeScript fence — a JSON body under a `json` tag is exactly right by its classifier
`check:doc-types`	judges the `type` literal and, in its own words, deliberately not the snippet's other keys
`check:doc-expression-carriage`	⭐ the ONLY gate that reads `json` fence bodies — and it is report-only, and its declared tolerance list REMOVES line and block comments and re-escapes raw newlines BEFORE parsing. ⇒ the two shapes that make a fence uncopyable are normalized away by design; it printed 「225 json/jsonc fence(s), 225 parsed, 0 UNPARSED」 on a tree carrying 22 that `JSON.parse` refuses

⭐ That last row is the finding under the finding: the repo HAS an instrument over this corpus, and its tolerances are calibrated to make exactly this class invisible. ⛔ Not a defect in that gate — it was built for a different question — but it is why nobody noticed.

⚠️ One unmeasured neighbour, recorded so it is not mistaken for checked

content/docs/guide/schema-rendering.md's Memoization subsection asserts 「the renderer automatically memoizes components to prevent unnecessary re-renders」. ⛔ No measurement was taken in either direction, by the dev or by this seat. It is on the same page as two of the 22 and is the same class of claim as the lazyLoad promise objectui#9989 just removed after measuring it false. ⇒ whoever takes this card is the natural reader; ⛔ it is recorded as unmeasured, ⛔ not asserted to be false.

Acceptance

The conventions are named: what a deliberately non-parsing fence looks like and how a reader tells it from a mistake.
Every fence not covered by a named convention parses, re-measured on the tree at that moment with the control lit in the same command.
Whether a gate blocks is answered — and if the answer is 「it should」, that is raised as its own decision rather than landed inside this card. ⛔ Gate strength is not this lane's to grant itself.

File surface: the json-tagged fences that fail JSON.parse under content/docs/** (PM probe, a lead only: guide/expressions.md, guide/layout.md, utilities/runner.mdx, fields/location.mdx, guide/deployment.md, guide/record-edit-modes.md, guide/schema-rendering.md, guide/troubleshooting.md, plugins/index.md, utilities/vscode-extension.mdx) plus the ONE existing gate that reads those fences, if its normalisation is what hides them (strengthened, not a new gate) (stop on breach; explain in the report) — amended in the same round as the delivery (bounded in-place exemption, named in PR objectui#10942): packages/types/src/__tests__/page-actions-refusal-7926.test.ts (it pinned the exact count of the unparseable guide/layout.md fences this card fixes, 4 → 0) and .changeset/10088-json-fences-parse.md (empty frontmatter, owed because that test sits under src/); REWORK round 1 (contract review 5867033932) adds CONTRIBUTING.md (one paragraph in ### Writing Documentation naming the json/jsonc fence convention)
Container & model: M, mode:subagent, model: opus (default tier; no path-derived mandate for content/docs/** or scripts/)
Clause-②: no — published docs examples and a repo gate; no accept set or public contract surface moves
Thread-read: none
Serial constraints cleared: GET /pulls/{n}/files over all 22 open objectui PRs (2,016 filenames examined, read before this claim): the docs pages open PRs touch are plugins/plugin-view.mdx (objectui#10937), guide/dashboard-filters.md (#10930), plugins/plugin-timeline.mdx (#10901), plugins/plugin-grid.mdx (#10278) — none is on this card's list; no open PR touches a doc-snippet / doc-example gate script.

Premise re-checked at claim time on origin/main 733fd5ac65 (PM probe, re-measure owed by the dev): 209 json-tagged fences under content/docs, 24 fail a strict JSON parse (the card read 22 of 198 on 2026-09-20); control — the same parser rejects a trailing comma.

Counter-examples still parse, because each one's fault is semantic, not syntactic. I did not tighten the carriage gate. Its tolerances are there for a documented reason, and tightening it would make JSON validity blocking through an existing test pin, which is a gate-strength decision the card reserves (see open_questions). page-actions-refusal-7926.test.ts pinned layout.md's 4 unparseable fences by exact count; it now pins 0, so those 4 page nodes are judged.",

The PM probe's 209/24 also counted the 6 jsonc fences, 3 of which fail strict parse. fields/location.mdx and record-edit-modes.md are correctly tagged jsonc and parse as JSONC. troubleshooting.md:369 was a jsonc fence holding 3 documents; it failed both JSONC instruments and was fixed in-surface.",
"H2": "The gate is scripts/check-doc-expression-carriage.mjs, the report-only census. HOLDS but understated: it normalises FIVE shapes the 21 used, not two. They are comments (tolerance 1), raw newlines (2), elisions (4), the object-body retry, and several top-level documents (splitTopLevel), and it applies them to json and jsonc alike. At base it printed "231 json/jsonc fence(s), 231 parsed, 0 UNPARSED (1 parsed as an object body)". Tightening it is NOT an honest strengthening inside this lane, for two reasons. (1) Its header states the purpose: judge ${…} carriage inside annotated fences, and "reaches 0 unparsed over the whole tree, which takes four tolerances". (2) Its test "has no blind spot on the corpus it ships against" asserts census.unparsed is empty, and it runs on every content/docs PR (markdown-test-inputs --changed names all 8 touched pages, so ci.yml runs the full test job). Strict json would therefore BLOCK merges on non-JSON json fences, which is the gate-strength call the card reserves.",

"A — Tighten the EXISTING carriage census: parse json strictly and keep the tolerances for jsonc only, ideally by importing parseJsonFence from check-skill-examples.mjs so both doc trees share one json/jsonc contract. Its existing pin "has no blind spot on the corpus it ships against" then blocks a non-JSON json fence on the PR that adds it. That pin already runs on every content/docs PR. No new script or workflow; a few lines plus fixture pins; content/docs is at 0 today, so it lands green.",
"B — No gate. The convention lives in this PR and in check-skill-examples.mjs only. Zero cost, but drift returns: the class went from 0 to 22 on main with nothing reading it.",
"C — A new dedicated json-fence gate. Default no (新增门禁默认否), and no maintainer has named one."

"recommendation": "A, pending the maintainer. 实际业务需求: measured, not assumed. 21 non-parsing json fences accumulated on main while one normalising instrument read them all green, and the skills tree already enforces the identical contract for its fences (objectui#7474, check-skill-examples). 长远合理性: one json/jsonc contract across both doc trees, carried by an instrument and pin that already exist. The cost is that the carriage census answers a second question (tag grammar), which is mitigated because it already prints parse coverage per language. 防AI写错: a json fence is what an AI copies into a metadata file; a strict, loud check beats the tolerant normalisation that hid this class. 创业阶段不扩散: A adds no gate, script or workflow. It still flips blocking strength on a new class, so it needs the maintainer's yes, which is why it is not in this PR."

Implemented-by: os-dev subagent of this session, branch claude/issue-10088-json-fences-parse · Reviewed-by: this seat · Contract review at CONTRACT_REVIEW_TIER: PASS on this head (5867275230); the round-0 record (5867033932) FAILED on acceptance #1 and this head closes exactly that item.

Acceptance, line by line

Conventions named, where an author meets them ✓ — one paragraph in CONTRIBUTING.md › ### Writing Documentation, beside the existing fence-tag rule: json = strict JSON.parse, annotation only under jsonc, the rewrites for the shapes no dialect admits, the same contract as the skills checker's parseJsonFence, and that nothing enforces it for content/docs today (every claim verified true on this tree by the contract review).
Every fence not covered by a named convention parses, re-measured with a lit control ✓ — dev reading at head: 203 json fences, 0 failing; 11 jsonc, 0 failing under both JSONC instruments. The seat's own pre-dispatch probe had found 24 failing across the two tags; the per-fence table (22 edits) is in the PR body and every edit was judged right by the contract review (no example changed meaning, no counter-example became a positive one, no dropped comment was a page's only statement of a fact).
Whether a gate blocks is answered ✓ — the dev did ⛔ not tighten the carriage census inside this card; the question is raised as its own decision, objectui#10943 (A/B/C, this seat recommends A).

Shape: draft ✓ · base main ✓ · first line Fixes #10088 ✓ · the only closing keyword ✓ · Clause-②: no ✓ · assignee ✓.
Path face: 8 content/docs pages, CONTRIBUTING.md, packages/types/src/__tests__/page-actions-refusal-7926.test.ts (its pin counted the unparseable guide/layout.md fences 4 → now 0; still guards by name) and an empty-frontmatter changeset ✓ — the test and changeset under the bounded in-place exemption, CONTRIBUTING.md by the REWORK; the claim's file surface was amended in the same rounds. Not governed.
CI on 6da92addb3: 43 check runs, 40 success, 3 by-design skips, 0 failures — read by this seat. Commit trailers model-free ✓. mcp_calls 0.

Out-of-scope findings: packages/vscode-extension/README.md carries a json fence with // comments — it would be the one UNPARSED fence under option A, so it is added to objectui#10943's execution note (not filed separately). guide/layout.md's maxWidth / padding on a page node and guide/schema-rendering.md's Memoization claim stay unmeasured — Acceptance notes, not filed (no measured wrong answer yet).

Landing now: ready + auto-merge through the merge queue.

The reading, taken by this seat on `origin/main`

Why a reader is harmed: the failure lands BEFORE the schema

⚠️ Why this is a triage call and ⛔ NOT a drive-by fix

Measured by the #9989 dev, ⛔ NOT re-run by this seat: why no gate catches it

⚠️ One unmeasured neighbour, recorded so it is not mistaken for checked
