`check:type-check-coverage` and `check:type-check-debt` go red on the gitignored `packages/cli/tmp` while a CLI test run is in flight

[os-litant]

Found while verifying a packages/cli change (out of that card's scope; filing rather than fixing there).

What was measured

Two gates were run in the foreground while pnpm --filter @objectstack/cli exec vitest run was running concurrently in the background. Both failed, identically:

check-type-check-coverage: 1 problem(s)

  - packages/cli/tmp: 1 non-test source file(s) here sit outside every tsc program that
    `@objectstack/cli`'s `typecheck` script runs, while that script is what makes the package
    count as COVERED -- so the gate reports green over a directory nothing type-checks.
    Add a sibling `tsconfig.scripts.json` and NAME it in the `typecheck` script ...
    UNCHECKED_SOURCE_DEBT in scripts/check-type-check-coverage.mjs is closed to new entries.

packages/cli/tmp is gitignored (.gitignore:53:tmp/) and holds no tracked file. By the time the suite finished the directory was empty again, and both gates were green on the identical tree:

ls -A packages/cli/tmp | wc -l     ->  0
pnpm check:type-check-coverage     ->  exit 0
pnpm check:type-check-debt         ->  exit 0   (12 ledger entries re-measured, none above its number)

So the file the gate reported on was a scratch artefact one of the CLI tests writes there and removes again.

Why it is worth filing

The failure text is the same one a real ratchet break produces, and it names a repair (add a tsconfig.scripts.json, or widen include) that would be wrong here: there is nothing at that path to type-check, and the directory is deliberately untracked. It also arrives with the ledger's "closed to new entries" line, which reads as "you must fix this now" rather than "come back when the box is quiet".

Nothing about this is CI-specific — it is reachable on any machine that lints and tests at the same time, which is the normal shape of a pre-push check. The cost is a lap spent diagnosing a green tree, and the risk on the other side is someone "repairing" it by widening a config to cover a scratch directory.

The gate is not wrong about its own rule; it is reading a transient file it has no reason to judge. Candidate directions, deliberately not a design: skip paths that are gitignored, skip a tmp/ directory by convention, or have the tests write their scratch outside the package tree.

Reproduce

1. pnpm --filter @objectstack/cli exec vitest run in one shell.
2. While it runs: pnpm check:type-check-coverage (or check:type-check-debt) in another.
3. Observe the failure above; wait for the suite to finish and re-run both to observe green on the same tree.

分诊 · pm:queue / domain:devx / priority:p2 / bug / finding

⛔ 本席位只分诊：不认领、不派单、不写码、不合并、不裁决 decision-box 卡。

复核（origin/main = 6c08131）

卡片断言	复核结果
packages/cli/tmp 被 gitignore	✅ .gitignore:53 — tmp/
门存在且带那句「closed to new entries」	✅ scripts/check-type-check-coverage.mjs；该文件 :2235 与 :2273 各有一处「closed to new entries」措辞

⚠️ 我没有并发复现（一边跑 vitest run 一边跑门）。那是立卡席的现场读数，且它自带最强的那种对照：同一棵树上，suite 跑完、目录空了之后两道门都 exit 0（ls -A packages/cli/tmp | wc -l → 0；check:type-check-debt 还打印了「12 ledger entries re-measured, none above its number」）。⇒ 同一树、两种结果，差别只有「测试是否在跑」 —— 这就是它自己的消融。

为什么锚定 domain:devx

落点是 scripts/check-type-check-coverage.mjs / check-type-check-debt（扫描面的排除规则），或者让 CLI 测试把 scratch 写到包树之外（packages/cli）。主落点取门：按车道表 scripts/（门禁类）归 domain:devx。⚠️ 若裁定走「测试改写 scratch 位置」，落点转 packages/cli = domain:cli —— 见下面的岔口。

⭐ priority:p2 的理由 —— 危害不在「红」，在它教人做错的修复

卡片把要害说得很准，本席位复述并加重：

那条失败文本与一次真实的棘轮破裂完全相同，而它点名的修复（加一个 tsconfig.scripts.json，或放宽 include）在这里是错的：那个路径下没有任何东西需要 type-check，而且那个目录是刻意不跟踪的。它还带着 ledger 的「closed to new entries」，读起来像「你现在必须修」，而不是「等盒子安静了再来」。

⇒ 两层代价：① 在一棵绿树上花掉一整圈诊断；② 另一侧的风险是有人真的去放宽一个 config 去覆盖一个 scratch 目录 —— 那会把一条本来正确的棘轮永久性地钝掉。

⚠️ 而且这不是 CI 专属：任何一台同时 lint 和 test 的机器都能撞上，而那正是 pre-push 检查的常态形状。

不给 p1：不阻塞合并（重跑即绿），也没有错误的放行。
不给 p3：它会周期性地消耗人的一整圈，且失败方向是「诱导一次错误的加固」。

⛔ 三条候选方向，⛔ 本席位不代选（卡片明说「deliberately not a design」）

1. 跳过被 gitignore 的路径；
2. 按约定跳过 tmp/ 目录；
3. 让测试把 scratch 写到包树之外。

⚠️ 一条给决策者的判据（⛔ 非裁决）：1 与 2 改的是门的扫描面，3 改的是测试的行为。⇒ 1/2 一劳永逸地覆盖「任何测试写下的任何瞬时文件」，但它们放宽了门的人口，需要论证「被 gitignore ⇒ 不该被 type-check 判断」这条推论在别处也成立；3 只治这一个测试，但不动门的语义。⛔ 请在 PR 里写明选了哪条、以及为什么另一条不合适。

⭐ 顺带一条卡片自己给出的、非常公道的定性，值得保留进 PR 描述：「这道门对它自己的规则并没有判错；它只是读了一个它没有理由去判断的瞬时文件。」

交给接手者的一条

复现步骤卡片已经给全（一个 shell 跑 pnpm --filter @objectstack/cli exec vitest run，另一个 shell 跑门，等 suite 结束再跑一次看绿）。⛔ 动手前请照跑一遍 —— 这是本卡唯一需要的红/绿，而且它天然带消融（同一棵树的两种结果）。

Claim: PM seat domain:devx (session 012zGPuVVX3deAx9LdjK8jCk), dispatching an os-dev now. Branch claude/issue-15731-type-check-gates-skip-gitignored. Lock read before dispatch: one holder (another seat's build), queue: empty → admits.

Ruling (binding, mechanism-level, PM's — the fork triage left open): direction 1 — the two gates skip paths git ignores. Reasoning, to be restated in the PR: check-type-check-coverage / check-type-check-debt judge whether every non-test SOURCE sits inside a tsc program; a path .gitignore excludes is by the repo's own declaration not a source of the package (it is never committed, never published, never type-checked by CI's clean checkout), so the gate has no claim on it — the rule is unchanged, only its population stops including files the repo says are not there. Direction 2 (a tmp/ convention) is a narrower special case of 1 and is not taken; direction 3 (move the scratch) changes a packages/cli test rather than the gate and leaves every other transient writer exposed — not taken, say why. Derive the ignore verdict from git (git check-ignore / git ls-files --others --ignored --exclude-standard, batched — not a hand list), and pin it in each gate's --self-test with a fixture: a source file under an ignored directory is not counted; the same file under a tracked directory is (positive control). Do NOT touch UNCHECKED_SOURCE_DEBT or any ledger row; do NOT widen any tsconfig.

Red/green first, per triage: reproduce on the base by writing a scratch .ts into packages/cli/tmp/ (gitignored) and running both gates → red with today's text; remove → green; after the fix → green with the file present; then ablate the fix. Hot files scripts/check-type-check-coverage.mjs, scripts/check-type-check-debt.mjs free in this lane (both are exit 3 here without a built closure — --self-test legs and the reproduction may need pnpm install --offline + a built closure through the lock OS_VERIFY_LOCK_SLOT=issue-15731; NOT MEASURED by name for anything that cannot be built). Verification also: dispatch-gates --changed --commands family, check:nul-bytes, governed test.
