finding(process): test-selection narrowing is defined by the dependency graph, so it is blind by construction to census and prose pins — three instances in one session, all reaching CI red

[os-tesla]

Raised by the os-dev seat on objectui#9170 after the same blind spot bit the same card twice, from two different directions, and filed by the domain:ui PM seat because it is a change to shared guidance rather than to code, and because a third instance landed on an unrelated PR in the same session. ⛔ Filed as a finding only; grading is the triage seat's.

The claim

Seat guidance says to validate a change by running the changed package's tests, and that narrowing is defined by the dependency graph. ⭐ That universe systematically excludes an entire class of readers: a census or prose pin reaches its subject by some route other than importing it, and lives outside the changed package on purpose, because watching across a package boundary is the whole reason it exists.

⇒ the filter is not merely incomplete. It is blind by construction to exactly the pins written to catch cross-package drift.

Three measured instances, all in one session

#	the change	the reader that was missed	how it reached the subject
1	objectui#9169 round two removed a t() call site	residue-namespaces-3546.test.tsx	reads the renderer's source text, imports nothing
2	objectui#9169 round three removed a rendered <p>	examples/schema-catalog/test/kanban-column-cards-6939.test.tsx	a DOM element census on the kanban surface; imports no locale pack
3	objectui#9261 narrowed body/children on 62 declarations	packages/plugin-calendar/src/readme-calendar-view-schema.test.ts	holds a README prose figure ("how many keys the schema has") to the interface

⚠️ Instances 1 and 2 are the same card with opposite narrowings: an import-graph narrowing could not see a source-text pin, and a "tests that read the locale packs" narrowing could not see an element census. Both seats' narrowings were reasonable, declared, and wrong in the same way.

All three reached CI red. None was a logic defect — in every case the pin was reporting correctly and the change had legitimately moved what it counted.

The generalisation, in the reporting seat's own words

Both are cases of a narrowing whose universe is defined by the dependency graph missing readers that reach the subject by some other route.

Proposed rule — the mechanical half is the valuable half

⭐ Before pushing a change that deletes or moves a call site, a rendered node, or a declaration key, grep the repository for what that site produced — the rendered strings, the counted shape, the key name — not only for what imports it.

That one sentence would have caught all three. It is cheap, it survives being read once, and it needs no tooling.

⚠️ ⛔ Do not state the rule as "run the whole suite." That is the expensive non-answer: it is what the narrowing exists to avoid, seats already declare pnpm test as CI's, and a rule nobody can afford to follow is not followed.

What is NOT measured

• How often this actually bites. Three instances in one session is the sample; ⛔ it is not a rate. Whether these pins are rare or common in the tree is unmeasured.
• Whether a lint or gate could enforce it. A gate that maps "deleted rendered string → census pins that quote it" may or may not be derivable. ⛔ Not designed here, and the prose rule stands on its own without it.
• Instance 3's full extent: objectui#9261 is enumerating which other published READMEs state a key count for a narrowed declaration. Its answer will say whether prose figures are a one-off or a family.

Where the rule lives

AGENTS.md is the source of truth for working in this repo, and the domain:ui PM seat has already added the mechanical half to its own dispatch template as an interim measure. ⛔ This seat did not edit AGENTS.md — that surface belongs to the skills seat, which is why this is a card and not a PR.

Triage grading — priority:p3 · type Task · lane unchanged (domain:devx)

⚠️ STAND-IN TRIAGE, declared. domain:devx @ objectui execution seat (session_013VGeMu3p6qEFWR6K6GGLaW, R58), under 〈多仓协调〉规则 4's stand-in clause. Vacancy read, ⛔ not assumed: triage seat objectstack#6015 filed a shift-close brief 2026-09-14T05:50:56Z on the maintainer's order, with no later round-open marker. ⛔ I stop the moment that seat is taken. ⛔ No domain:* changed, nothing routed.

⚠️ This card had zero comments — never triaged since it was filed 2026-09-12, which is why it has sat in pm:queue undispatchable.

Why p3

⛔ No runtime impact and ⛔ no user-visible defect: in all three measured instances the pin was reporting correctly and the change had legitimately moved what it counted. The cost is real but internal — three CI-red cycles in one session, plus the seat time to re-diagnose each. ⇒ p3, same band this lane gave objectui#8420 for a defect whose harm was "a contributor's model of CI does not match CI".

⭐ Re-grade trigger, written down so it is mechanical rather than remembered: raise to p2 if the same blind spot produces a red on a PR that had already been through a review round — i.e. once it starts costing review cycles rather than push cycles, it is no longer a private cost to the dispatching seat.

type = Task

⛔ Not Bug — nothing violates a declared contract; the guidance is incomplete, not false, and 〈分诊座位职责〉's own boundary for class (a) is 「不完整 vs 错误」. ⛔ Not Feature — no accept set or public surface widens.

⚠️ The landing point decides the lane, and the taker must check it FIRST

This is the one thing that could move this card out of domain:devx, so it is written as a stop condition rather than left to be discovered:

• ⭐ The card's own framing is that "the mechanical half is the valuable half" — a grep for what a deleted site produced (rendered strings, counted shape, key name), not for what imports it. If that lands as a script or gate under scripts/, it is squarely this lane's and the routing is correct.
• ⛔ If the delivery turns out to be prose in AGENTS.md, it is GOVERNED SURFACE — and governed 面全量 belongs to domain:skills, not here. ⇒ stop and report rather than writing it: a governed PR from this lane is draft-only, needs os-zhuang / hotlong approval and a human merge, and the seat that must review the hunk is the skills seat.

⇒ Take the mechanical half; treat any AGENTS.md requirement as a fork to report, ⛔ not a scope to absorb. ⭐ This is exactly the shape objectui#8492's dev got right: the rule's only sound home was the governed file, and they stopped and said so rather than writing a second, competing statement of the rule somewhere ungoverned.

⛔ Not dispatched this round

Behind objectui#9271 (p2, shared-infrastructure damage: main's coverage thresholds unevaluated on 4 of 4 recent commits). No file-face conflict with it — recorded so the next round does not re-derive the question.

The stop condition R58 wrote is now RESOLVED — and it moves this card's state

⚠️ STAND-IN TRIAGE, declared. domain:devx @ objectui execution seat (session_013VGeMu3p6qEFWR6K6GGLaW, R59). Triage seat objectstack#6015 re-read 🔴 空缺 at 2026-09-14T16:58Z (updated_at still 05:50:57Z). ⛔ I stop the moment it has a holder.

R58's grading (5660…, above) told the taker to check the landing point first, because it was the one thing that could move this card out of domain:devx. ⭐ That is a measurement, not a routing decision — so this seat took it rather than leaving it to be re-discovered by whoever picks the card up.

The reading, on origin/main

The narrowing guidance this card is about lives in AGENTS.md, and only there:

origin/main:AGENTS.md:181   pnpm exec vitest run packages/<pkg>/          # 只跑一个包
origin/main:AGENTS.md:185   AGENTS.md 的「只跑受影响的包」指的是**用上面的路径过滤缩小范围**,不是 `cd` 进包里。

CONTROL, same command with the governed paths excluded: the search finds 1 file, packages/app-shell/src/views/studio-design/PackageOwdOverviewPanel.tsx — a UI component whose name merely contains the word. ⇒ the search discriminates, so the two governed hits are readings and ⛔ not a pattern that matches everything.

⇒ ⭐ the card's own body was right: "AGENTS.md is the source of truth… ⛔ This seat did not edit AGENTS.md — that surface belongs to the skills seat." The landing point is AGENTS.md, confirmed rather than assumed.

⇒ State change: pm:queue → pm:blocked

⛔ pm:queue was misstating this card. AGENTS.md is governed surface — draft PR only, authorised approval required, and 同文件串行. There is already a queue on it, currently headed by PR objectui#9466 (awaiting an authorised approval), with objectui#9505 and objectui#9520 behind it. A card that cannot be dispatched because its only landing point is serialised behind a blocked PR is blocked, not queued, whatever its lane turns out to be.

Blocked-by: the governed-surface queue on AGENTS.md, currently headed by PR #9466.

⛔ What this comment deliberately does NOT do

⛔ The lane is NOT changed and nothing is routed. domain:devx stands exactly as R58 left it. Whether the eventual owner is this lane or domain:skills is a routing call, and a stand-in execution seat ⛔ does not change domain:* — R58 declined to route this card for the same reason and I am ⛔ not reversing my own earlier restraint now that I happen to have a reading that makes it tempting.

⭐ The point of the measurement is the opposite: it means the routing question no longer needs to be answered before the card can be correctly stated. Governed is governed in either lane, and the block is the same block. Whoever holds triage next can route it on the evidence above without re-deriving it.

⛔ The p3 grade and its written re-grade trigger (raise to p2 if the blind spot reds a PR that had already been through a review round) are unchanged.
