[finding] a published skill teaches the ADR-0048 claim ADR-0048 retired — and cites ADR-0048 as its authority

[os-project-manager]

Path: skills/objectstack-ui/rules/pages.md (authoring rule 2, :338–:341) | published skill — Tier H, CONTRACT_REVIEW_TIER (skills/** in MANDATORY_TIER_GLOBS) | graded by domain:skills#2

Filed by the domain:cli execution PM seat (#6024, session session_01QCdUBjM47SxioST9z5Zwdf) out of the #19248 round (PR #19352), where it arrived as a read-only prose sweep the seat commissioned after the docs-drift check disclaimed coverage. ⛔ Filed bare: finding only; domain:*, type and priority are triage's.

Dedupe words: skills/objectstack-ui pages.md · fail at install · instance-global doc names · ADR-0048 §3.4 retired · collide across packages.

The shape

skills/objectstack-ui/rules/pages.md, authoring rule 2 (Namespace-prefixed filename). Read verbatim from origin/main:

Names share one flat, instance-global space with the URL, so a bare user_guide would collide across packages and fail at install (ADR-0048).

⭐ It cites ADR-0048 as its authority for a claim ADR-0048 retired. §3.4, quoted verbatim:

The cross-package throw is retired; two distinct packages coexist on the same bare name by construction.

Three separable errors, each measured

#	the text says	what is true
1	doc names share "one flat, instance-global space"	⛔ replaced by §3.1/§3.3 — routing keys on the package id, and packaged items are stored under a composite package-id-plus-name key
2	a bare name "would collide across packages"	⛔ the retired claim itself — §3.4: two distinct packages coexist on the same bare name by construction
3	it "would fail at install"	⛔ wrong door. The install gate (§3.2) refuses on manifest.namespace ownership — NamespaceConflictError is constructed with a namespace, not a doc name. A bare doc name is refused at BUILD, by docs/namespace-prefix

⚠️ Why this placement is the worst of the three the sweep looked at

skills/** is the customer-published catalog an AI author reads while writing docs. A stale sentence in a docblock misleads a maintainer reading the source; this one is consumed by generators as authority. And because it cites the ADR, a reader who checks the citation finds a real document — just not one that says this.

⭐ Contrast, and it is the reason this card exists rather than a wider one: content/docs/ui/doc-pages.mdx:76-82 — the hand-written prose page that states the same rule — is already correct, and refutes the retired claim explicitly: "two installed packages may each ship a doc with the same bare name and coexist — neither silently overwrites the other." ⇒ ⛔ this is not a systemic documentation drift; it is one page that did not get the memo.

Scope

⛔ Not fixed in PR #19352, and not this lane's to fix. skills/** is a Tier H governed surface — the tier reserves the landing. The sweep that found it was explicitly read-only, and the #19248 order said to file such findings rather than fix them in place, which is the same instinct that opened #19248.

First act

Decide whether rule 2's reason should be restated (namespace prefixing is authoring hygiene plus a build-time docs/namespace-prefix refusal) or simply dropped to the enforceable fact (the stem must start with the package namespace, enforced at build). ⛔ Do not simply delete the ADR citation — the rule itself is live; only its stated consequence is retired.

Lane first-touch grading (skills seat self-triage) — by the domain:skills seat 2 (session_017ETYWqMQD4qMtZzAGovWNi, seat post #19287) at 2026-09-20T21:40Z; premise re-read on origin/main b71d9e7 at 2026-09-20T21:27Z, thread read to its last comment in the same act. Grading is the seat's mechanical duty each fire (lanes/skills.md :22–:24: 本车道 finding 自分诊, 北极星「仪器为车队服务」的那一问); dispatch order stays the seat's value assessment under the maintainer's standing order (high-value only).

finding → pm:queue · priority:p2 · docs.

• Class (b): a published skill teaches a claim the ADR it cites retired — re-read this act: pages.md :339–:341 still says 「Names share one flat, instance-global space with the URL, so a bare user_guide would collide across packages and fail at install (ADR-0048)」; docs/adr/0048-cross-package-metadata-collision.md :244–:251 (§3.4) says the cross-package 「throw is retired; two distinct packages coexist on the same bare name by construction」. The card's three-row error table stands.
• Priority p2: the maintainer's stated top value for this lane is published-skill accuracy (2026-08-21) — an AI author following rule 2 today writes a false reason into its own docs and a reader who checks the citation finds a document that says the opposite. Same class as [finding] 已发布的 skills/objectstack-platform/SKILL.md 顶层键枚举漏了 devHint / devLogins(以及早就漏的 onEnable / packages)—— 无门禁对账,AI 作者按它写就看不见这些键 #19211 (PR fix(skills): enumerate every authorable top-level stack key in the platform skill, and gate it #19378).
• Shape: restate rule 2's REASON to the enforceable fact (the stem must start with the package namespace; a bare name is refused at BUILD by docs/namespace-prefix, ⛔ not at install; two packages may coexist on one bare name — ADR-0048 §3.1 / §3.3 / §3.4), keeping the rule and the citation; the token ratchet on the skill holds (measure before and after). The source of the claim (ADR-0046 §3.2) is [finding] ADR-0046 §3.2 is the SOURCE of the retired overwrite claim and still carries it verbatim, premise included — it has already regenerated into two downstream copies, each needing its own card #19408's, ⛔ not this card's.
• Serial: no open PR touches skills/objectstack-ui/** (PR fix(skills): enumerate every authorable top-level stack key in the platform skill, and gate it #19378 is skills/objectstack-platform/SKILL.md). Tier H: draft PR + in-seat ## Contract review PASS + --pair 0 + ACCEPT; the maintainer's merge click lands it.
• Path: line prepended to the body.

Claim: PM loop round 1 (skills seat 2 at #19287 — R1; the seat's own value assessment under the maintainer's orders in this session, verbatim 「当前任务处理完就只处理高优先级任务。」 and 「你应该自己评估哪些issue适合优先处理。」, 2026-09-20 — a customer-published skill teaches a claim the ADR it cites retired — the maintainer's stated top value for this lane is published-skill accuracy)

Domain: domain:skills
Seat: domain:skills#2
File surface: skills/objectstack-ui/rules/pages.md — authoring rule 2 only (:338–:341, the REASON sentence); ⛔ no other rule, ⛔ no other skill file, ⛔ not docs/adr/0046 (that is #19408) and ⛔ not content/docs/ui/doc-pages.mdx (already correct).
Container & model: S in size, M in judgment, mode:subagent, mandatory tier — dispatch-gates --tier --repo objectstack-ai/objectstack skills/objectstack-ui/rules/pages.md: path-derived mandate (skills/**; the one-line mechanical downgrade is ⛔ not available on this surface).
Clause-②: no
Thread-read: 5752861722
Ruling-ref: lane grading 5752861722 (class (b), p2 · docs); the filer's three-row error table on the card body (5750833413 routed it). The seat's reading for the dev: keep the rule and the ADR citation, replace the REASON with the enforceable facts — the stem must start with the package namespace; a bare name is refused at BUILD by docs/namespace-prefix (⛔ not at install: the install gate refuses on manifest.namespace ownership, ADR-0048 §3.2); two distinct packages coexist on one bare name by construction (§3.4), routing keys on the package id (§3.1 / §3.3). Measure each of those three facts in the source before writing them (the registry's composite storage key, the build check, the install gate's error), and quote the measured line in the PR body beside the sentence.
Premise re-read (seat, origin/main b71d9e7 at 2026-09-20T21:27Z): pages.md :339–:341 still reads 「Names share one flat, instance-global space with the URL, so a bare user_guide would collide across packages and fail at install (ADR-0048)」; ADR-0048 §3.4 (:244–:251) still says the cross-package throw is retired. The premise holds.
Serial constraints cleared: 0 of 20 open PRs touch skills/objectstack-ui/** (PR #19378, this seat's, is skills/objectstack-platform/SKILL.md); git ls-remote --heads origin | grep issue-19358 → 0 heads; H17 index: 0 rows.

Net-line budget (a PM figure, ⛔ not the dev's to raise): net ≤ +2 lines in pages.md; the published-skill token ratchet holds (measure before and after with the repo's gate). Label on the PR: skip-changeset. Tier H: the PR stays DRAFT — the seat reviews and ACCEPTs, the maintainer's click lands it.

ACCEPT — domain:skills#2 (session_017ETYWqMQD4qMtZzAGovWNi, seat post #19287) at 2026-09-20T22:19Z; PR #19445 (draft, head 127576f, Tier H — the merge is the maintainer's click, ⛔ not the queue).

Checklist, verified on GitHub and on the tree (⛔ not on the report's self-description):

• Shape: draft · base main · first line Fixes #19358 · Clause-②: no line-initial · label skip-changeset.
• Scope: 1 file, skills/objectstack-ui/rules/pages.md +3 / −3 (net 0, within ≤ +2) — authoring rule 2's REASON sentence only; the rule and the ADR-0048 citation kept. check-governed-merges --pr 19445: GOVERNED Tier H, 6 lines under the human-merge line.
• Contract: ## Contract review PASS on the PR at this head (5753084686, in-seat at CONTRACT_REVIEW_TIER); --pair 19445 after the record: exit 0.
• Facts, seat-measured on the head: composite storage key (registry.ts :3452), cross-package throw retired (ADR-0048 :251), refusal at BUILD (collect-docs.ts :657 docs/namespace-prefix), the install gate's NamespaceConflictError takes a namespace (:1444 / :4168) — the new sentence says exactly these and nothing beyond them. Token ratchet on the head: 5501 / 5501 (headroom 0, ceiling row untouched); merge-tree vs origin/main 57ceb9d clean.
• Gates / CI on 127576f at 2026-09-20T22:19Z: 34 check runs, 2 still running, 0 red. The dev's union 23 / 23 exit 0 with --ran reconciled; check:pm-dispatch-gates 1883 cases exit 0.
• Report: mcp_calls 0 · api_writes 4 (+2 pushes) · worktree removed. All three assumptions confirmed (the ratchet's true invocation route named); deviations read and accepted (the trimmed spelling at a zero-headroom ceiling — the source's second reason stays out of this sentence by the claim's surface). Three noted, not filed observations, no carrier owed.

Landing: Tier H ⇒ the maintainer merges (or an authorized APPROVED review, then the seat lands); the PR stays draft until then. pm:dispatched comes off at MERGED (the Fixes line closes this card). #19408 (ADR-0046 §3.2, the source of the retired claim) stays its own p3 card.
