[finding] `.claude/agents/os-dev.md` states sibling repos have no `scripts/pm/` — objectui has one, and a dispatch built on that premise reached a governed file this shift

[os-justin]

Found by the domain:skills dev seat while writing references/lanes/ui.md (branch claude/issue-17236-lanes-ui-md, PR #17243), measured on origin/main 559e531a, 2026-09-09. Not in that PR's scope, so it is filed rather than fixed there.

The claim

.claude/agents/os-dev.md, in the 本地验证范围 section's gate-family derivation rules, verbatim:

读之前先核对;姊妹仓(objectui / cloud)没有 scripts/pm/。

The measurement

Repo-scoped REST against objectui main:

GET /repos/objectstack-ai/objectui/contents/scripts/pm?ref=main
  -> ["check-half-states.mjs"]                     # HTTP 200
GET /repos/objectstack-ai/objectui/contents/.github/workflows/half-state-patrol.yml?ref=main
  -> HTTP 200

Control, same session, same channel, against a path that genuinely is absent there:

objectui scripts/pm/dispatch-gates.mjs   -> absent   # the control fires: the reader can say "no"

⇒ objectui does have a scripts/pm/. It holds one file, the adopted copy of this repo's half-state sweeper, and a live standing caller (.github/workflows/half-state-patrol.yml, cron 4×/day). The two most recent scheduled runs are green.

What is still true, and what is not

• Still true — the operative instruction. scripts/pm/dispatch-gates.mjs does not exist in objectui, so objectui's gate families must be derived by hand from that repo's own package.json and .github/workflows/. Nothing in that half changes.
• Not true — the stated premise. The sentence generalises from one absent tool to an absent directory, and it names cloud in the same breath (⛔ not measured here — this finding claims nothing about cloud).

Why it is worth a card rather than a note

The false half is load-bearing in exactly one direction: an agent that reads it and needs to know whether objectui has a half-state sweeper, a verify lock, or any other scripts/pm/ tool gets a confident "no" from the repo's own operational text.

That is not hypothetical this shift. The dispatch brief for #17236 carried the same premise («objectui has no half-state-patrol.yml and no dispatch-gates.mjs») and asked the dev to write the half-state-patrol line of a governed lane charter from it. The measurement above falsified it in time and the file records what is actually there — but the premise came within one unchecked line of being versioned into .claude/.

Re-check

curl -s -H "Accept: application/vnd.github+json" \
  https://api.github.com/repos/objectstack-ai/objectui/contents/scripts/pm?ref=main
# expect: one entry, check-half-states.mjs

grep -n "没有 .scripts/pm/" .claude/agents/os-dev.md
# expect: one hit, in the gate-derivation rules

Admission class

Class (a): an error, not an omission — a stated fact that measurement contradicts, in operational text every dev agent reads. The remedy is a one-line correction (name the missing TOOL, not an absent directory), plus a decision on whether the cloud half of the same sentence has ever been measured.

Triage (skills-lane finding self-triage; the triage seat is vacant): lands in .claude/agents/os-dev.md — the one sentence in the 本地验证范围 gate-derivation rules, 「读之前先核对;姊妹仓(objectui / cloud)没有 scripts/pm/」 (present at e669e5e, one hit); rationale: class (a), an error not an omission — objectui main has scripts/pm/check-half-states.mjs and a live half-state-patrol.yml (the card's REST reading, with its control), while the operative half (no dispatch-gates.mjs there ⇒ derive families by hand) stays true. Remedy: name the missing TOOL, not an absent directory; the cloud half of the sentence is dropped with it rather than measured (cloud is attached to no seat, and a sentence that claims nothing about cloud cannot be wrong about it — no decision owed). pm:queue · Bug · priority:p3. Value gate (#13597): ① yes — a dev deriving objectui's gate families reads a confident "no" today; ② rewrite in place, net-zero; ③ the construct is the tool name. Tier: os-dev.md is a clause-① file; a one-line mechanical correction may build at the floor tier at PM discretion, compensated by the skills-seat review at the contract-review tier. Serial: os-dev.md is free (no open PR touches it; the lane's only live branches are this round's three claims). Skills seat, session session_01YKEjmbYNvYWJvWGSWx26zK, 2026-09-10T09:11Z.

Container & model: S mechanical (a one-sentence factual correction; the shape is fixed by the card's measurement), mode:subagent, model: opus — dispatch-gates.mjs --tier .claude/agents/os-dev.md prints the clause-① MANDATORY claude-fable-5-1 line for this path with the stated exit 「a one-line-class mechanical governed edit drops to opus execution … compensated by the skill-face review at claude-fable-5-1」; exit taken (one-line class, judged from the card content); review = skills-seat self-review at the contract-review tier.

The one sentence in .claude/agents/os-dev.md was rewritten in place to name the missing TOOL instead of an absent directory, and no longer asserts anything about cloud, which is attached to no seat here. The operative half is untouched: a sibling without dispatch-gates.mjs still derives its gate families by hand from its own package.json and .github/workflows/. Assumption A held (git grep for the sibling-repo term hits exactly two lines in the file: the worktree-per-repo rule and this one, so one rewrite closes the claim); assumption B held (no twin outside the declared surface; the pm-dispatch references speak about this repo's tree or about the derivation answering only its own tree, and lanes/hotcrm.md's patrol-carrier clause is consistent with the corrected sentence); assumption C held only as a subset, see gates.

ACCEPT — PR #17375 (head b0d88290) reviewed in-seat at the contract-review tier (skills seat, session session_01YKEjmbYNvYWJvWGSWx26zK, 2026-09-10T10:08Z).

• Implemented-by: os-dev subagent on branch claude/issue-17244-os-dev-sibling-scripts-pm (claim 5616639272; build tier opus via the one-line-class exit, recorded on the claim; mode:subagent). Reviewed-by: session_01YKEjmbYNvYWJvWGSWx26zK (the skills seat) — independence pair holds; the seat's harness reading is the tier evidence.
• PR shape: draft; base main; first line Fixes #17244; skip-changeset. Changed files read from the PR: exactly one, .claude/agents/os-dev.md, +1/−1.
• Diff read on the fetched head: :149 「读之前先核对;姊妹仓(objectui / cloud)没有 scripts/pm/。」 → 「读之前先核对;姊妹仓未必有 scripts/pm/dispatch-gates.mjs:objectui 只有 check-half-states.mjs。」 (114 B); 403 → 403 lines; the false pattern has zero hits on the head; the operative neighbours (:150–:152, hand-derive from the sibling's package.json + workflows, --repo assertion) untouched. The sentence now names the missing tool and asserts nothing about cloud — the card's remedy exactly.
• Measurement re-run by this seat at review: objectui origin/main a646262 scripts/pm/ = check-half-states.mjs only (control: no dispatch-gates.mjs) — matches the dev's reading and the card's.
• Gates (dev, at b0d88290): 17 derived families run, 17 exit 0, --ran reconciled; check:pm-skill-ratchet 「os-dev.md is 403 lines (ceiling 403; headroom 0)」; pm-skill-id-lint 27 clean; nul-bytes clean; doc-formula-expressions prerequisite then exit 0 under the verify lock. Not re-run locally by this seat (single text line; counts and width re-measured on the fetched head).
• CI on b0d88290 at 10:07Z: 28 check runs — 13 success, 12 skipped, 3 in progress (Lint & Repo Gates, Type Check · consumer gates, Type Check · source gates); re-read at the next patrol before this record is cited as green.
• Zone-2: A and B hold; C narrower than the real derivation (the dev ran the wider set) — accepted. Deviations accepted: the build to clear a gate prerequisite; pm-governed-prose run beyond the derived set.
• Out of scope, noted, not filed: the sibling-repo term is no longer enumerated in-file (AGENTS.md Prime Directive Migrate documentation site to Fumadocs with monorepo structure and shared content #11 defines it; 承接者: none today); check-half-states.mjs already records objectui's single file (承接者: none).
• Terminal: governed (.claude/**) ⇒ the PR stays draft; needs-user-decision placed on PR docs(agents): name the missing tool, not an absent sibling scripts/pm/ #17375, 速读 终稿 posted there, reviews requested from os-zhuang and hotlong; ⛔ not flipped ready, not enqueued, no auto-merge, no approval from this seat. On MERGED: landing record here + pm:dispatched / assignee cleared in one write with read-back.
