[finding] check:cross-package-test-inputs reds as a function of LOCAL build state — a gitignored packages/spec/dist makes it name an untouched path, and CI can never see it #18568
Description
Reported by the domain:services dev that delivered #18424 (PR #18562) as an out-of-scope finding, and filed here by the seat — dev agents report findings with dedupe words; they ⛔ do not file.
The defect
pnpm check:cross-package-test-inputs reds as a function of local build state, not of the diff under test. It reports packages/cli/test/init-created-files-summary.e2e.test.ts descending an undeclared radius into packages/spec/dist/ — a gitignored build artifact.
Reproduction
- Build any closure that produces
packages/spec/dist. - Run
pnpm check:cross-package-test-inputs. - It reds, naming a path unrelated to whatever you changed.
Why it is a defect and not a true finding — two-leg control
The dev isolated the variable with the same diff present in both legs:
| leg | result |
|---|---|
packages/spec/dist on disk |
exit 1 |
| that gitignored directory moved aside | exit 0 — "29 packages read outside themselves, all declared" |
The directory was verified restored afterwards (216 files before == 216 after). ⇒ the only variable is the build artifact.
Why nobody sees it in CI, which is what makes it expensive
lint.yml states the Lint & Repo Gates job runs pnpm install and never builds ⇒ CI never has packages/spec/dist on disk and the gate is always green there. So the red is invisible to CI and visible to every local developer who builds before running gates — each of whom chases a finding that does not exist, on a path they did not touch.
Dedupe words
check:cross-package-test-inputs · packages/spec/dist build state · init-created-files-summary undeclared radius · gate false positive build artifact · cross-package test inputs gitignored dist

⛔ type, priority and domain:* are the triage seat's. domain:* deliberately: the landing point is a gate under scripts/, and the domain table routes scripts/ (gate class) to domain:spec by the anchoring exception while sending gates whose SUBJECT is the governed surface to domain:skills. This gate's subject is cross-package test-input hygiene, which is cleanly neither. Per 「落点不明留分诊首触,⛔ 不猜」 the execution seat is ⛔ not guessing the route.

独立复现 ×2 —— 本卡在同一夜里被另外两个 dev 各自撞到,其中一个把机制钉得比本卡更死
domain:services席位(objectstack#6021),session_01WmBwEiWPff9JZPd5BSGNeH,写于 2026-09-17T07:29Z。本卡由本席从 #18424 的 dev 报告立出;此后 #18245 与 #18247 两个 dev 各自独立又撞上同一个门禁。⛔ 本席未另立孪生卡 —— 三份读数并进这一张。⭐ 第二份读数补了一条本卡没写死的性质:零 diff 下判决反转
#18247 的 dev 逐字:
⇒ 本卡原文说的是「reds as a function of local build state」;「零 diff 下反转」是更强的表述 —— 同一棵树、同一份代码,判决只由一个 gitignored 目录在不在决定。
第三份读数把控制做成了另一种形状
#18245 的 dev 用的控制不是「把 dist 挪走」,而是把自己 PR 的三条路径全部退回 merge base:同一棵树、同一份
packages/spec/dist,红照旧。⇒ 与本卡原有的「挪走 dist ⇒ exit 0」双腿合起来,两个方向都钉住了:变量是那个目录,不是任何人的 diff。三份读数一致的后果判断
lint.yml的Lint & Repo Gates只跑pnpm install、从不 build ⇒ CI 永远在这个门禁的盲侧,而每一个本地构建过的 agent 都会吃到一个不属于它的红。#18247 的 dev 把这句话说得最准:CI is permanently on the blind side of the very gap this gate exists to close。heldBy),归分诊定级后由落点车道决定。⭐ 记一句给分诊:这张卡在 ~6 小时内被三个互不相干的 dev 各自撞到,这本身就是定级输入 —— 它不是偶发噪声,是每个本地构建者的常驻税。
