   Claim: PM loop round 5 — unblocked when #15667 closed (PR #15690 MERGED 04:26Z); the seat answers the card's two contract questions and dispatches the row

   File surface: scripts/pm/check-half-states.mjs only — the second half of H45: a pm:epic card whose parent's labels lack pm:epic (a child marked reserved under a parent that is not delegated), report-only, state class, over a SEPARATE pm:epic population read from the label index and kept out of seen (no existing row's input moves), using the sub-issues parent read (GET /repos/{o}/{r}/issues/{n}/parent, one call per pm:epic card, a 404 meaning parentless) as a new, declared fetch class; self-test cases in both directions; live run over both repos in the PR body. ⛔ No existing row's predicate or wording changes; ⛔ no other new fetch class (stop on breach; explain in the report)
   Container & model: S, mode:subagent, model: opus (dispatch-gates.mjs --tier scripts/pm/check-half-states.mjs: no path-derived mandate, read 02:3xZ for the sibling flight on the same file)
   Clause-②: no
   Serial constraints cleared: PR #15690 (#15667, H45/H46) MERGED 04:26Z — the last change to the file; no open PR touches it (scan 04:4xZ). Not governed ⇒ the seat's contract-tier review, then ready + auto-merge once every check is green. The PR carries Fixes #15702.

   Decision re-read (04:4xZ): the two questions the card poses are the seat's to answer on the sweep's contract, and are answered yes and yes above — the read is bounded by the pm:epic index (5 cards today), report-only, and the population is separate by construction. Triage's p3 stands; no ruling owed.

     "premise_still_valid": true,
     "summary": "Both contract questions answered as the seat ruled, and the row landed under H45 as a second sentence (one row id: every registry key matches /^H\\d+$/, so there are no sub-rows to name). New declared fetch class subIssueParentPath(repo, n) = GET /repos/{owner}/{repo}/issues/{n}/parent, one call per pm:epic carrier, its 404 'No parent issue found' counted as an ANSWER (parentless) and any other failure leaving the carrier UNJUDGED. The pm:epic index is enumerated as its own population, read LAST in sweepInto into a loop variable and never folded into `seen`; SEEN_LABEL_PAGES lifts the seven pages that do feed `seen` out of the loop body so the exclusion is checkable rather than re-typed. Reading pinned in the PR body: a top-level carrier is the delegated node when EITHER free signal says so (it heads a subtree, or its body carries the session_... registration, the machine half of the paired delegation signal in SKILL.md's epic section) - the live index refuses both single-signal readings in both directions, so an AND would report three of the five carriers. H45's first half is byte-identical: same predicate, same sentence, same free population. Report-only exit semantics unchanged.",
     "tests": "SELF-TEST: `node scripts/pm/check-half-states.mjs --self-test` -> verdict line 'check-half-states self-test: 2262 cases pass.' exit 0 (2223 before; +39 written, +1 generated by the shared SUMMARY_CLAUSE_ANCHORS coverage loop). Cases cover every shape ruled, both directions. ABLATION (3 legs, no build/dist sits between mutation and run - the self-test imports the same source path the mutation writes, and that is asserted by the blob-hash comparison rather than assumed; implementation was committed FIRST so HEAD is a real restore reference): (1) the parent-lacks-pm:epic branch made to return null -> RED, 4 of 2262; (2) 'pm:epic' added to SEEN_LABEL_PAGES -> RED, 2 of 2262; (3) the delegation-signal OR made an AND -> RED, 2 of 2262. Each leg proved the mutation ON DISK before reading anything - deleted-text and injected-text occurrence counts anchored on the text itself, plus the file's blob hash differing from `git rev-parse HEAD:scripts/pm/check-half-states.mjs` - and proved the restore the same way afterwards (blob hash back to HEAD's AND `git diff HEAD` empty), with an absolute-path trap on EXIT/INT/TERM. One leg was RE-RUN because its first disk proof was invalid: a multi-line grep -c counts LINES, so that reading was declared void and the leg redone with a single-line anchor. GATES: dispatch-gates.mjs --commands --repo objectstack-ai/objectstack derived 31 commands from the real changeset (1 path, three-dot vs merge base c2a336ca2); all 31 run, 30 exit 0. The one non-zero is `node scripts/check-partof-closing-keyword.mjs` exit 2, whose own text is 'NOT WIRED - neither PR_BODY nor PR_NUMBER is set ... This is a wiring or usage failure, NOT a verdict' = NOT MEASURED, not a red gate; it was then run with the real PR body in PR_BODY and printed 'check:partof-closing-keyword: this PR carries no Part-of/closing-keyword contradiction.' exit 0. `pnpm lint` (eslint . --no-inline-config, the WHOLE repo, not a narrowed run) through the shared lock: 'os-verify-lock: VERDICT command-exit 0 - held the lock 102s'. No vitest pin suite names this script; its --self-test is its suite. This file declares no battery floor (that mechanism lives in scripts/sync-template-versions.mjs), and the count line is computed. LIVE: five interleaved objectstack sweeps (2 pristine out-of-repo, 2 patched, 1 pristine IN PLACE via a swap-and-restore both proven by blob hash) - 18 of 25 rows identical in all five; every mover (H8, H19, H20, H36, H38, H46) is a live PR/branch/seat row and each moves between two PRISTINE runs too. H43 read NOT MEASURED in the two out-of-repo runs (their own words: the governed register is not beside the file) - a defect in my measurement method that the script itself caught; across the in-place pair it reads 5 = 5. objectui: 20 of 22 identical, both movers board rows. Row result: objectstack 5 of 5 parent reads answered, 0 flagged; objectui 0 of 0, 0 flagged. Cost is exactly +1 listing page and +1 read per carrier, shown by the sweep's own counter (objectstack 17 -> 18 pages, objectui 14 -> 15). CI on the draft PR at 3b29a22f6: all 35 check-runs reported - 24 success, 11 skipped, 0 failures, combined state success; 'Live half-state sweep' is among the successes, so the patched script also ran end-to-end on a runner. All measurements above were taken at 3b29a22f6, the branch tip (origin/main merged in first).",
     "mcp_calls": "1 - one directed search_issues, for the out-of-scope duplicate check after the container's /search REST route answered 403; the same call returned an already-closed same-class card as its live control. Everything else (issue and comment reads, the pm:epic index, the parent reads, label write, PR create, check-run polling) went over repo-scoped REST.",

       "filed as #15761: dispatch-gates offers the bare `node scripts/check-partof-closing-keyword.mjs` as a runnable local gate, but that guard takes PR_BODY/PR_NUMBER through the workflow's env: block rather than argv, so the tool's existing 'takes a VALUE FROM THE WORKFLOW / NOT MEASURED' bucket - which correctly caught four argv-carried families on the same run - never sees it, and the command can only ever exit 2 outside CI. Same class as the already-closed #14004 (check-governed-queue-guard), which did not generalise to the env-carried variant. Labelled finding/tooling/domain:devx, no assignee, ungraded."
