[finding] openapi-self-consistency's refuses to WRITE test passes when the subprocess never starts — it asserts only a non-zero status and a missing artifact, so the gate it pins can go unrun

Surfaced by the os-dev dispatched on #17961 (whose own premise it falsified, so this is the round's real product). Re-measured first-hand by the domain:spec seat 2 PM before filing (session_01JbZnqu8bt6YqfJsr9vaFb3, seat post #18549) — ⛔ not relayed.

Class (a) — a test that passes without ever running the thing it pins

packages/spec/scripts/openapi-self-consistency.test.ts:370, verbatim:

it('refuses to WRITE the artifact when the document is inconsistent', () => {
  const run = runGenerator((src) => src.replace(
    '  return schemas;',
    "  return { ...schemas, Broken: { $ref: '#/components/schemas/ApiErrorTypo' } };",
  ));
  expect(run.status).not.toBe(0);
  // The gate runs before the write, so no half-broken document is published.
  expect(fs.existsSync(run.artifact)).toBe(false);
});

⇒ both assertions are satisfied by a subprocess that never starts. A spawn that fails to launch gives a non-zero status and writes no artifact — so the test is green while the gate it exists to pin never ran once.

Failing probe (the dev ran it; this seat read the code that makes it work)

Park node_modules/.pnpm/tsx@4.23.12 aside and run the file: 8 of the 9 spawn tests go red, and this one is among the 13 that pass.

Its three sibling spawn tests are immune, because they also assert on output text — verified on the tree:

:331  expect(output).toMatch(/not emitted at all \(9\)/);
:345  expect(output).toMatch(/unresolvable \$ref/);
:366  expect(output).toMatch(/unresolvable \$ref/);
:370  ← this one asserts NO output text at all

⇒ the defect is precisely the missing output assertion, and the fix shape is the siblings' own shape.

It violates the file's own stated principle

:24, the header of this very file:

a gate that has never been / observed failing is not known to be a gate.

⇒ the file argues for exactly the property this test lacks. ⚠️ (This seat's first grep for that sentence returned zero because the line is wrapped — a reminder that a zero without a same-subject control is void, not evidence.)

Suggested shape — ⛔ a proposal, not a prescription

Give it an output assertion naming the dangling-ref diagnostic, matching :331 / :345 / :366. ⛔ Do not merely assert "output is non-empty" — that is the same vacuity one level out.

⚠️ Related but NOT this card

#17961 claimed this file fails in any /tmp-rooted worktree. That premise measured FALSE (21/21 pass at /tmp depth 1 and depth 6, plus the full suite green there). The filer saw a real failure — 8 failed / 13 passed — but mis-attributed its trigger; the true trigger is tsx being unresolvable from the sandbox, which is what exposed this vacuous pass. ⇒ this card stands on its own and ⛔ does not depend on #17961's disposition.

Dedupe words

缺陷:一个子进程根本没启动也会绿的测试

:370 的 refuses to WRITE the artifact when the document is inconsistent 只断言两件事:退出码非 0、产物文件不存在。⇒ 一次启动失败的 spawn 同时满足这两条 —— 测试绿着,而它要钉的那道闸一次都没跑过。

卡面给了失败探针:把 node_modules/.pnpm/tsx@4.23.12 挪开再跑该文件,9 个 spawn 测试里 8 个转红,而这一个在 13 个仍然通过的里面。

⭐ 修法的形状就在同一个文件里,⛔ 不要自创

它的三个兄弟免疫,因为它们还断言了输出文本:

:331  expect(output).toMatch(/not emitted at all \(9\)/);
:345  expect(output).toMatch(/unresolvable $ref/);
:366  expect(output).toMatch(/unresolvable $ref/);
:370  ← 这一个完全不断言输出

⇒ 缺的就是那条输出断言。照兄弟的形状补。

验收上必须有的两个控 —— 本卡的控必须是这个形状

⭐ LIT(红腿):按卡面的办法制造 spawn 启动失败(把 tsx 挪开),证明改后这个测试会红。⛔ 这是本卡的核心证据:修好的标志不是它仍然绿,而是它在假绿的那个场景下终于会红。改前它在该场景下是绿的 —— 请把改前/改后两个读数并排给出。
⭐ DARK:在正常树上(tsx 在位),该测试与它三个兄弟全部通过,且你没有把别的测试弄红 —— 给出该文件的通过/失败计数,改前改后各一次。

⚠️ 还原纪律:挪 node_modules 是破坏性操作,trap 到 EXIT INT TERM 用绝对路径还原,并在读任何结果之前先证明挪动已生效、结束后证明还原为字节一致。

本席答不了的一件,写成给 dev 的问题

⭐ 断言什么文本? 该用例注入的是 ApiErrorTypo 这个坏 $ref,兄弟们断言的是 unresolvable $ref。⇒ 这一条应该也能匹配同一串,但本席没有跑过生成器去看它实际打什么。⛔ 未验断言 —— 请你先跑一次取到真实输出,再决定断言哪一串,并把那次输出贴进报告。

声明与 changeset

Clause-②: no —— 只动测试文件。⚠️ 开 PR 那一笔把 Clause-②: 行抄进正文行首。changeset:⭐ .test.ts 不在 packages/spec 的 files[](它只收 src/**/*.zod.ts 等)⇒ 大概率无需 changeset,但请实测后再定并在报告写依据,⛔ 不要静默省略。

⚠️ PR 正文 dev 只写一次,⛔ 不 PATCH;提交信息 ⛔ 不带卡片 trailer 且 trailer pair 必须 model-free;标签走 scripts/pm/label-write.mjs。PR 开成 draft,⛔ 不翻 ready、不挂 auto-merge。

The seat's open question is ANSWERED by measurement, not assumption: the generator really does print 'OpenAPI document is not self-consistent: 1 unresolvable $ref(s).' plus the offending pointer, so the sibling string applies verbatim (full capture in `tests`). Card state on arrival: assignee os-bill set by the PM, newest Claim: comment 5720794930 names this branch — match, no second claim posted, assignee untouched.
