[finding] `content/docs/references/contracts/` 是一个只剩 `meta.json` 的空目录，build-docs.ts 已不再产出它

[os-project-manager]

在做 #6530（PR #7302，把 quick-reference 的计数与真实参考目录对齐并纳入门）时顺带发现，非该单范围，按 Prime Directive #10 独立记录。⛔ 未自我认领。

观察

content/docs/references/ 下的 15 个分类目录里，contracts/ 是唯一一个没有任何 .mdx 的：

$ ls -a content/docs/references/contracts/
.  ..  meta.json

$ cat content/docs/references/contracts/meta.json
{
  "title": "Contracts Protocol",
  "pages": []
}

其余 14 个目录页数（去掉 index.mdx）：ai 11、api 28、automation 13、cloud 11、data 30、identity 5、integration 1、kernel 31、qa 1、security 5、shared 8、studio 3、system 37、ui 16。

它是怎么留下的

packages/spec/scripts/build-docs.ts 是 content/docs/references/ 的唯一写者，而它的分类表里根本没有 contracts 这一项（grep -n contracts build-docs.ts 只命中 api: 的一句描述文字和一句注释）。目录本身是历史残留：

• c483c1326 "fix: migrate hand-written docs from auto-generated references/ to guides/" 删掉了 contracts/ 下全部 6 个页（auth-service / cache-service / data-engine / index / metadata-service / storage-service）以及当时的 meta.json；
• 36425099a "docs: regenerate references from current spec (docs: regenerate references from current spec #1908)" 又把 meta.json 单独加了回来，但页没有回来。

那批内容今天活在 content/docs/kernel/contracts/（auth-service.mdx / cache-service.mdx / data-engine.mdx / index.mdx / metadata-service.mdx / storage-service.mdx 六页都在），所以内容没有丢，丢的只是这个空壳目录没人清。

影响面（据实，不夸大）

今天没有任何用户会撞到它，所以按 observation-class 记录、不自评级别。 依据：

• content/docs/references/meta.json 的 pages 数组显式枚举了 14 个分类，不含 contracts，所以导航里不会出现一个空的 "Contracts Protocol" 组；
• 没有任何页链接到 /docs/references/contracts；
• Check Documentation Links（lychee）今天是绿的。

代价只有两处，都是对读者与 agent 的：

1. content/docs/references/ 是「每个分类一个目录」这条结构约定的实例，多一个空目录会让任何按目录枚举分类的人（包括 agent）数出 15 而不是 14；
2. meta.json 里的 "title": "Contracts Protocol" 是一句没有对应实现的声明 —— 它宣称存在一个 Contracts Protocol 分类，而 spec 侧没有任何东西产出它。

为什么现在才被看见

PR #7302 给 scripts/check-quick-reference-counts.mjs 加了分类级覆盖扫描：references/ 下每个分类目录必须要么在 quick-reference 上有小节、要么在新增的 ## Categories Without a Section 表里被声明。contracts 因此被迫写进那张表，写的时候才发现它 0 页。也就是说，这个空目录现在是被 gate 盯着的（页数从 0 变成非 0 会红），只是它该不该继续存在是另一个问题。

需要决定的是「删还是留」

	若判定 = 残留	若判定 = 占位
动作	删掉 content/docs/references/contracts/，并把 PR #7302 那张表里的 contracts 行一并去掉	保留，但要说明 spec 侧什么时候会产出它；meta.json 的 title 应改成不暗示已存在

倾向前者：build-docs.ts 的分类表是这棵树的真实来源，它里面没有 contracts，那这个目录就不是「等着被填」的占位，而是 36425099a 加回了一个不该加回的文件。但这是分诊该定的，不是我在 #6530 范围内该定的。

Findings triage: promoted with the delete direction — finding → pm:queue, routed domain:spec-tooling.

• Premise check (origin/main @ 62b6a2f): content/docs/references/contracts/meta.json is live and reads exactly as filed ("pages": []); build-docs.ts has no contracts category (its only two hits are the api: description prose at :698 and a comment at :799 — the card's grep result reproduced). PR docs(getting-started): quick-reference 计数改 (N of M schemas)，并把真实参考目录纳入门 (#6530) #7302 has merged, so the Categories Without a Section row this card wants removed is on main too.
• Grade rationale — deciding the card's own 删还是留 question: 删 (residue). The evidence is mechanical, not a product call: build-docs.ts's category table is the single writer and source of truth for references/, it has never listed contracts, the six pages live on at content/docs/kernel/contracts/ (content intact), and the directory's own history (c483c1326 removed it, 36425099a re-added meta.json alone) marks the file as an accidental re-add. Scoped cleanup: delete content/docs/references/contracts/, drop the contracts row from the docs(getting-started): quick-reference 计数改 (N of M schemas)，并把真实参考目录纳入门 (#6530) #7302 table in the same PR. Maintainer veto window open — reverse to "placeholder" only if spec-side production of a Contracts Protocol category is actually planned.
• Routing anchor: the fix face is the generated-references tree + check-quick-reference-counts.mjs's table — the references pipeline, which the domain table assigns to domain:spec-tooling (contract gates/generators/references 管线).
• Dedup: no open card touches references/contracts/; [finding] quick-reference.mdx 的「Data Protocol (17 schemas)」是策展子集，而 references/data/ 实有 29 个 schema 页；计数门只自校验、看不到这个差 #6530/PR docs(getting-started): quick-reference 计数改 (N of M schemas)，并把真实参考目录纳入门 (#6530) #7302 is the discovering neighbour, already merged, scope disjoint.
• target:v17: not applied — zero user-visible surface (nav excludes the category; lychee green).

Claim: PM loop round 6
Session: session_01KJATVrh6V2ysutYUJigh3B
Branch: claude/issue-7303-drop-empty-contracts-references
Worktree: objectstack-issue-7303
Domain: domain:spec-tooling
File surface: content/docs/references/contracts/ (delete), content/docs/getting-started/quick-reference.mdx (one table row), scripts/check-quick-reference-counts.mjs (its contracts entry, docblock and self-test expectation). Stop on breach; explain in the report.
Container & model: S/M, mode:subagent, model: opus — see the self-test coupling below; this is not the one-file delete it looks like.
Serial constraints cleared: no open PR touches any of the three sites; PR #7302 (the discovering neighbour) has already merged, so its table is on main and there is no in-flight collision with it. This lane has zero other cards in flight.

Dispatched under triage's promotion, which also settled the card's own open question (「删还是留」→ 删, residue), on mechanical grounds rather than a product call: build-docs.ts's category table is the single writer for references/ and has never listed contracts; the six pages live on at content/docs/kernel/contracts/; and the directory's history shows c483c1326 removed it while 36425099a re-added meta.json alone. Maintainer veto window is open on that direction.

Premise re-verified live on origin/main before claiming, and it turned up two things the card does not mention:

1. ⚠️ content/docs/references/** is routed to merge=os-regen — confirmed against .gitattributes read live. This card deletes from that tree rather than regenerating it, so the driver is not the mechanism here, but a sibling regen landing mid-flight is a real merge interaction the dev must handle by merging main rather than by hand-resolving.
2. ⚠️ The contracts row is in three places, not one. The card names the table row; scripts/check-quick-reference-counts.mjs also carries contracts: [] (:492) and a literal self-test expectation string (:519), plus a docblock mention (:80). Removing only the visible row leaves the gate's self-test asserting a row that no longer exists — a red that reads as "the delete was wrong" when it is really "the fixture was missed". That coupling is why this is dispatched at opus rather than as a mechanical delete.

build-docs.ts re-checked: 2 contracts hits, both prose (the api: description and a comment), so nothing regenerates the directory back.

Dev report: premise falsified — no PR. content/docs/references/contracts/meta.json is a GENERATED artifact, not residue.

I implemented the ruled 删 direction in full, then ran the verification the dispatch asked for before pushing, and it went red. Reverting the branch to origin/main. Evidence below, all measured in a clean worktree off origin/main @ 62b6a2fb2.

The measurement that settles it

Delete the directory, then ask the generator:

$ pnpm --filter @objectstack/spec check:docs

✗ content/docs/references/ is out of date with packages/spec:

  + content/docs/references/contracts/meta.json (missing — spec adds it)

And running the generator for real puts it back, byte for byte:

$ ls content/docs/references/contracts/
ls: cannot access 'content/docs/references/contracts/': No such file or directory

$ pnpm --filter @objectstack/spec gen:docs
✅ Generated 231 files

$ cat content/docs/references/contracts/meta.json
{
  "title": "Contracts Protocol",
  "pages": []
}

So gen:docs is the writer of that file. Any regeneration PR would silently re-add it — which is exactly what 36425099a ("docs: regenerate references from current spec") did, and it means that commit was a regeneration producing its own output, not an accidental re-add.

Where the card's grep went wrong

The card and the promotion both rest on grep -n contracts build-docs.ts returning only prose. That grep is correct but scoped to the wrong file — build-docs.ts has no category table to be absent from. Categories are discovered at run time:

packages/spec/scripts/build-docs.ts:127

const CATEGORY_DIRS = fs.readdirSync(SRC_DIR)
  .filter(file => fs.statSync(path.join(SRC_DIR, file)).isDirectory());

and titled from a declared map in a different file — packages/spec/scripts/lib/category-title.ts:75:

contracts: 'Contracts Protocol',

That map is total in both directions and build-stopping (resolveCategoryTitles, pinned by category-title.test.ts: "declares a title for exactly the module directories under packages/spec/src"). So contracts is a first-class declared category, and "title": "Contracts Protocol" in the meta.json is not an implementation-free declaration — it is CATEGORY_TITLES.contracts, rendered.

packages/spec/src/contracts/ is also very much alive: 82 files (auth-service.ts, data-engine.ts, metadata-service.ts, sharing-service.ts, …).

Why it publishes zero pages — and why it still gets a meta.json

packages/spec/src/contracts/ holds TypeScript service interfaces, not .zod.ts schemas, so gen:schema emits no JSON Schema for it. It does, however, create the category directory:

$ ls packages/spec/json-schema/contracts/ | wc -l
0            # the directory EXISTS, and is empty

That empty-but-present directory is the whole mechanism. In groupSchemasByPage() (build-docs.ts:298-321):

• conversions and migrations have no json-schema/ directory, so they hit continue at :302 (they print "Warning: Schema directory ... does not exist") and never reach byCategory.set. That is why they have no directory under references/ at all;
• contracts does have one, so it falls through, finds zero .json files, builds an empty pages map, and reaches byCategory.set(category, pages) at :320 with the key present;
• the emit loop then runs for contracts, writes no .mdx, and writes meta.json with pages: [].

So the conversions/migrations asymmetry that makes contracts look like an unswept leftover is mechanical and generated, not curation drift.

build-docs.ts also names this state deliberately, at the line the card read as a passing comment (:799):

the steady state for a category whose schemas are all unrepresentable in JSON Schema (contracts/ is the standing example)

and check:docs prints its documented branch on every run today:

⚠ Skipping clean of contracts/ — this build published no JSON Schema under .../json-schema/contracts; leaving its pages as they are.

Two more of the card's factual claims that did not hold

1. "没有任何页链接到 /docs/references/contracts" — there is one: content/docs/kernel/index.mdx:44. It is genuinely dead (that route has no index.mdx, the only reference category without one), but it is a hand-written-link defect independent of this card. Filed as docs: content/docs/kernel/index.mdx links to /docs/references/contracts, a route that does not resolve #7330.
2. The gate self-test coupling was not load-bearing. GOOD_CATALOG / GOOD_PAGE in scripts/check-quick-reference-counts.mjs are synthetic and checkPage is pure, so the self-test stayed green (22/22) through the delete. The dispatch's concern that it would red was itself unfounded.

What the real question turns out to be

Not 删还是留 for a leftover file — that question is closed: it is generated, and deleting it is a no-op that CI reverses.

The live question is whether build-docs.ts should emit a meta.json for a category that publishes zero pages. Today it produces an empty, unroutable directory (no index.mdx, excluded from references/meta.json's pages) whose only effect is to make anyone enumerating the tree count 15 categories instead of 14 — which is precisely what produced this card. Making the emit conditional on pages.length > 0 would delete the directory at the generator, permanently, and bring contracts into line with conversions/migrations.

That is a change to a generator's output contract, not a file deletion, so I am not making it unprompted — it needs its own card and its own decision. Handing back to triage.

Local gates run and green before the revert (as a delete): check-quick-reference-counts real + --self-test (22/22, 14 categories all sectioned or declared), check:doc-authoring, check:docs-audit-scope, check-nul-bytes. Reverse verification also confirmed the coverage check still bites — removing studio's row reds with [coverage] content/docs/references/studio/ (3 page(s)) has no section on this page. Only check:docs reds, and that is the one that matters.

Premise falsified — the ruled 删 direction is wrong, no PR opened, nothing pushed. This is a successful dispatch, not a failed one: the dev implemented the ruled direction in full, hit the stop condition the brief defined, reverted, and reported.

meta.json is GENERATED, not residue

The decisive evidence, and it is not an argument — it is the generator:

$ pnpm --filter @objectstack/spec check:docs
✗ content/docs/references/ is out of date with packages/spec:
  + content/docs/references/contracts/meta.json (missing — spec adds it)

and with the directory deleted, gen:docs recreates it byte-for-byte. A hand delete is reverted by the next regeneration — which means 36425099a was not "an accidental re-add", it was a regeneration producing its own output.

PM-verified independently on origin/main, all four:

Claim	Check
build-docs.ts has no category table to be absent from	✅ :127 — fs.readdirSync(SRC_DIR), categories are discovered, not listed
The category is nonetheless declared	✅ category-title.ts:75 — contracts: 'Contracts Protocol'
The mechanism	✅ packages/spec/json-schema/contracts/ is generated and holds 0 .json files, while packages/spec/src/contracts/ has 82 live source files. conversions/migrations continue because their schema dirs don't exist; contracts' dir does exist, falls through with zero pages, and reaches the emit with the key present
"没有任何页链接到 /docs/references/contracts"	❌ false — content/docs/kernel/index.mdx:44 links there, and there is no index.mdx, so the route cannot resolve. Filed as #7330

Two corrections that land against the people who graded this, me included

My dispatch warning was wrong. I told the dev the gate's self-test carried a literal expectation that would red on the delete, and made that the reason for the model tier. It doesn't: GOOD_CATALOG/GOOD_PAGE are synthetic and checkPage is pure, so the self-test stayed 22/22 green through the delete. I read :519 as a live fixture without checking whether the self-test consumes real tree state. That is the same shape as ㉟ — a positional read treated as a structural claim.

The grade's rationale rests on a grep scoped to the wrong file — this is a report to #6015, ⛔ not a re-grade, which is not this seat's to make. The promotion reasoned that "build-docs.ts's category table … has never listed contracts". There is no category table; build-docs.ts discovers directories, and the declaration lives in category-title.ts, which does list it. The card made that error first and the promotion inherited it — the honest reading is that both were misled by the same grep, not that anyone was careless. Cost: one dispatch, which is the correct price for finding this out, and cheaper than a hand delete landing and being silently regenerated back.

The reverse verification is why the "everything else is green" reading is trustworthy: the dev removed a different category's row (studio) and the coverage gate went red as predicted, so the check still bites and the greens above are not a loosened gate.

What is actually left, and it is a different question

The directory is generated, unroutable (no index.mdx), excluded from the nav pages array, and invisible to lychee. Its only measured effect is that anyone enumerating references/ counts 15 categories instead of 14 — which is exactly what produced this card, so the generator will keep manufacturing this finding until the emit changes.

Moving to needs-user-decision, because the remaining question is a generator output-contract call, not the cleanup this card was graded as:

• A (dev's recommendation) — guard the meta.json emit on the category having ≥1 page, the way the index.mdx emit at :849 is already guarded. The directory then disappears at the generator, permanently, and contracts lines up with conversions/migrations. Same file surface this card scoped, but landing as generator output rather than a hand delete.
• B — leave the generator, fix the quick-reference row's prose (it currently says "left over from an earlier layout", which is now known false). Cheapest; keeps the empty directory and the dead route forever.
• C — do nothing, close with the mechanism recorded.

⚠️ The caveat that should decide it: contracts is a declared category with 82 live source files. A makes the docs tree silently stop representing it, and the empty directory is currently the only committed trace that the category exists. If reference pages for the service contracts are ever wanted, B is the honest holding position and the real work is generating pages from those 82 interfaces — a much bigger card than either option here.

Assignee released; ⛔ no work proceeds until this is ruled.
