finding(.claude/agents): os-dev.md:279 tells every dev to copy a Clause-②: line into the PR body for a reader objectui does not have — and an objectui claim has no such line to copy

.claude/agents/os-dev.md:279 tells every dispatched dev, unconditionally:

正文行首照抄认领的 Clause-②: 行:Check Changeset 读正文不读卡,开 PR 那一笔就带上。

⚠️ Both halves of that line are repo-conditional, and the file says so nowhere. Measured this act by a dev working an objectui card (objectui#9874) and re-taken at source by the seat:

There may be nothing to copy. The claim comment on an objectui card carries no Clause-②: line — the line is produced by the clause-② flow, which is a domain:spec / domain:skills mechanism. The dev followed the instruction, found no source line, and reported it rather than inventing one.
The reader the rationale names does not exist in that repo. objectui has no check-clause2-carriers.mjs, and its own gate says so verbatim — objectui:scripts/check-governed-queue-guard.mjs:1959, read on origin/main 00c4df509:

⚠️ objectui has no check-clause2-carriers.mjs to defer the verdict question

Control from the same command: changeset occurs in five objectui workflow files (changelog.yml 4, changeset-guard.yml 31, changeset-presence.yml 37, changeset-release.yml 119, ci.yml 10) ⇒ the instrument reads that corpus; the absence is a reading, ⛔ not a failed search.

⇒ ⭐ in objectstack the line is right: scripts/pm/check-clause2-carriers.mjs exists and its own header describes a dual carrier, selecting 「the claim comment SELECTED as the carrier」 with the PR body as the second limb. ⛔ In objectui the same sentence instructs a dev to satisfy a reader that is not there.

What this card does ⛔ NOT claim

⛔ Not that the dev was blocked: nothing was copied because there was nothing to copy, the PR opened normally, and no gate complained. The cost is a dev spending a step on a non-existent obligation and a seat spending a reading to confirm it — ⛔ not a broken landing.
⛔ Not a proposal to delete the line. The right shape (make it conditional on the repo, or on the claim actually carrying the line, or name the dual carrier's owning lane) is the skills seat's call, ⛔ not this seat's.

Claim: PM loop round 1 (skills seat 2 at #19287 — R1, concurrency 5: maintainer direct dispatch beyond the tier-2 list)
Session: session_017ETYWqMQD4qMtZzAGovWNi

Worktree: objectstack-issue-19096
Domain: domain:skills

File surface: .claude/agents/os-dev.md only — :279 at f93beea (「正文行首照抄认领的 Clause-②: 行:Check Changeset 读正文不读卡,开 PR 那一笔就带上。」) rewritten IN PLACE so the obligation holds only where the claim carries a Clause-②: line and the landing repository has the dual-carrier reader (scripts/pm/check-clause2-carriers.mjs exists in objectstack only; objectui's own gate says it has none), in the shape :68's landing-repo precedent already uses; net 0 on a zero-slack file (403 / 403); ⛔ no other line of the file (#19202's :284–:285 band and #18901's rule-3 band are other cards, queued behind on this seat's post); ⛔ no SKILL.md.
Container & model: S in size, M in judgment, mode:subagent, CONTRACT_REVIEW_TIER — dispatch-gates --tier --repo objectstack-ai/objectstack .claude/agents/os-dev.md at f93beea: the dev-agent definition is MANDATORY (clause ①: protocol semantics); the one-line mechanical exit is not taken because the line's condition is a judgment about two repositories, not a mechanical edit.
Clause-②: no
Thread-read: 5735181292
Ruling-ref: triage grading 5735181292 (class (a) · p2 · documentation · pm:queue; 「落实一个同族已确立的形状」 — an unconditional clause takes its condition from the landing repository, the shape #18882 landed at :68; three conditional shapes named, the skills seat picks) — and maintainer direct dispatch: the maintainer's line in this seat's session, verbatim: 「我要并发5 你看看本车道其他还有哪些任务可以派」 (2026-09-20, after 「并发保持5」); read as the lift of 北极星「优先级」第 3 条 for this card, chosen by the seat as a p2 on a file no first-tier or in-flight card holds. Seat-read premise this act: :279 unchanged on f93beea; the file's two latest landings (fe36a40 :285 on 2026-09-19; 87f776b on 2026-09-18) did not touch it.
Serial constraints cleared: 0 of 29 open PRs touch .claude/agents/os-dev.md (every open PR's file list enumerated at 2026-09-20T10:18Z; positive control on the same enumeration: scripts/pm/dispatch-gates.mjs 2 — PRs #19024, #19284); git ls-remote --heads origin | grep issue-19096 → 0 heads; #19202 and #18901 queue BEHIND on this seat's post (same file, region-level, ⛔ not a family); H17 index (anchor #9857 swept 2026-09-20T07:48Z): 0 rendered rows name this file.

Net-line budget (a PM figure, ⛔ not the dev's to raise): net 0 in .claude/agents/os-dev.md (403 / 403 at f93beea; the file is at its ceiling — every added line is paid by a retired one, named in the PR body). Label on the PR: skip-changeset (.claude/** is not published).

  "summary": "Rewrote os-dev.md :279 in place so the copy-the-Clause-②-line obligation is conditional on the claim comment actually carrying one (the PM's chosen shape: condition on the CLAIM, name the reader once, no repo named), keeps the `Check Changeset` reads-the-body rationale, and adds the negative branch (no line ⇒ zero write, ⛔ never fabricate). The dropped clause 「开 PR 那一笔就带上」 restates :56 (body written once on the PR-open write, no PATCH), so no rule is lost and no other line was retired. Assumptions 1–4 all held on 4efb988: :279 verbatim, `Clause-②` ×1, 403/403 pinned by scripts/pm/check-skill-line-ratchet.mjs CEILINGS with MAX_LINE_BYTES=120; objectstack reader scripts/pm/check-clause2-carriers.mjs (header: dual carrier, claim comment SELECTED as the carrier); objectui has none in its own words (scripts/check-governed-queue-guard.mjs :187 and :1959 at objectui origin/main 0c2eb5e; controls: 124 files in scripts/, 0 clause2 hits in the tracked tree); id-lint pattern /#[0-9]{3,}/ has 0 hits on the new line. Extra evidence for the shape: the carriers checker's own fixtures (:9306–9320) hold objectui claims WITH a Clause-②: line (objectui 7804 rows, later objectui 7696 row) and WITHOUT (first objectui 7696 row), so a repo-conditional line would be wrong in both directions while a claim-conditional one is true on every row.

ACCEPT — domain:skills#2 (session_017ETYWqMQD4qMtZzAGovWNi, seat post #19287) at 2026-09-20T10:47Z; PR #19305 (draft, head fba3bb3).

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

Shape: draft · base main · first line Fixes #19096 · Clause-②: no line-initial · the only closing keyword in the body is that one · no HTML comment · ## 维护者速读(草稿) present with 席位意见 empty · labels skip-changeset + size/xs + documentation.
Scope: 1 file, .claude/agents/os-dev.md, +1 / −1, net 0 (403 / 403); :279 measures 120 B on the head (cap 120); no other line touched (:284–:285 and the rule-3 band are other cards). check-governed-merges --pr 19305: GOVERNED, Tier S (席内达档复核落地), size +1 / −1.
Contract: ## Contract review PASS posted on the PR at this head (in-seat; served tier re-read before the act = CONTRACT_REVIEW_TIER); --pair 19305 re-run after the record.
Diff read by the seat: the obligation is conditional on the claim carrying the line, the reader is named, the negative branch forbids fabrication; the dropped 「开 PR 那一笔就带上」 survives at :56.
Gates: the dev's 19 derived families exit 0 with --ran reconciled; seat-run ratchet and id-lint on the head exit 0; CI on fba3bb3 at 2026-09-20T10:47Z: 30 check runs, all success or skipped except Lint & Repo Gates in progress.
Report: mcp_calls 0 · api_writes 3. Deviations read: base 4efb988 vs the cited f93beea (:279 unchanged between them); the suggested route's wording measured over the cap and was compressed — accepted, the condition, reader and negative branch all survive.
Out-of-scope: three noted, not filed; the census of repo-conditional clauses in this file is recorded on the seat post as a seat item, ⛔ not a card yet.

Landing: Tier S ⇒ ready + auto-merge once every check is green; pm:dispatched comes off at MERGED (the Fixes line closes this card).
