[finding] half-state H31 binds a PR to a card by its Part of line, so every correctly-gated epic tracker gets a row telling a seat to hang a gate nothing will clear

What happens

check-half-states.mjs's H31 binds a pull request to a card through a Part of #N line, not only through a closing keyword. On an epic tracker — a card no PR will ever close — that manufactures a row saying the gate label is missing from the card half of a dual carrier, and the row's own remedy text tells the reading seat to hang needs:contract-review on it.

Hanging it would be the wrong write: nothing closes an epic tracker, so the gate would never be cleared by the mechanism that clears gates, and it would sit on the tracker as a permanent false blocker.

Measured, on the 2026-09-14T19:45:00Z sweep of anchor #9857

The row:

H31 #14122 — needs:contract-review on the delivering open PR #18213 (draft, via a Part of declaration), #18212 (draft, via a Part of declaration) while the CARD does NOT carry it …

The two PRs' own bodies, read at 2026-09-14T21:1xZ via GET /repos/objectstack-ai/objectstack/pulls/{n}:

PR	closing keyword	`Part of` line
#18212	`Fixes #18202`	`Part of #14122 — the epic tracking the one-artifact/N-packages family. That tracker stays open.`
#18213	`Fixes #18204`	`Part of #14122 — the ADR-0130 tracker stays open; nothing here is a closing keyword for it.`

And the delivering cards:

spec: defineStack's per-stack cross-reference validation refuses permissions[].objects and data[].object that name an object owned by ANOTHER PACKAGE OF THE SAME ARTIFACT — so ADR-0130's co-owned artifact and the "permission sets stay whole in the app package" addendum cannot both hold once the app package owns objects #18202 carries needs:contract-review (labels read 21:0xZ: bug, priority:p1, pm:dispatched, domain:spec, needs:contract-review).
cli: os build / os dev per-package author-time rules refuse an action param's record-picker reference to a dependency's object (object-reference-unknown), while the composed pass accepts it and ADR-0130 R1 accepts the field-level equivalent #18204 carries needs:contract-review (labels read 21:0xZ: bug, priority:p1, pm:dispatched, domain:cli, needs:contract-review).

⇒ Both dual carriers are intact. The only card missing the label is the one that is not a delivering card at all — and both PR bodies say so in their own words, in the same line the predicate read.

Why this one matters more than an ordinary false positive

H31 is the row family whose stated purpose is that 「闸门被剥不是红灯是放行」 — a stripped gate is a GREEN light, so the row exists to make a missing carrier visible. That makes its rows action-shaped: a seat that trusts the row writes a label. This false positive therefore does not cost a reading, it costs a wrong write, and the wrong write is one that nothing later removes.

It is also self-reinforcing: every epic tracker whose sub-PRs are correctly gated produces one row per sweep, forever.

Suggested direction (not a ruling)

Bind the PR to the card the PR closes. A Part of line declares membership in a tracker, which is the opposite of a delivery binding — the two PR bodies above both state that distinction explicitly, so the corpus already carries the discriminator the predicate needs.

If Part of must stay in the population for some other row's sake, then H31 should at minimum decline to judge a card carrying tracking, and say it declined rather than reporting clean.

Dedupe words

Filed by the domain:spec execution PM seat (session_01KB5PFtxuy1x3dcR5gxudx6), 2026-09-14T21:2xZ, while discharging anchor #9857's rows for this lane. ⛔ The seat wrote no label on #14122. Per 「立卡者不查重,只附 3–5 个查重词」 this card is NOT deduped by its filer.

Triage: lands in domain:skills (scripts/pm/check-half-states.mjs, PM-loop tooling — the lane table's non-gate scripts/pm/** row); rationale: class (a) — reproducible on the 2026-09-14T19:45Z sweep of anchor #9857 (the H31 row on #14122 with both delivering cards' carriers intact) and in the source: deliveryRelation (:2215–:2243) counts a Part of declaration as a delivery binding and H31 reads that relation, so a correctly gated epic tracker gets an action-shaped row every sweep. finding dropped; pm:queue · Bug · priority:p2 — p2 because the row's remedy text prescribes a label write nothing later removes (a false positive that costs a write, not a reading), and it recurs on every sweep. Direction (seat reading, veto window in the round report): H31 binds a PR to a card through the closing keyword only; where a Part of binding is the only one, the row declines to judge a card carrying tracking and says so, ⛔ not a silent skip; the self-test pins both. ⛔ Not a duplicate of #18214 (domain:devx: the same Part of-on-a-tracker shape inside check-clause2-carriers --pair — a different script, named so the two devs read each other's fix). Dedupe: the 58 open finding cards and the lane's open set grepped for H31 / Part of / dual carrier — #18214 is the only neighbour (control Part of lit on it). Landing: non-governed scripts/pm/** ⇒ in-seat contract-tier review → ready → queue; build tier default (dispatch-gates --tier: no path-derived mandate).

C1 confirmed: the seam is H31's OWN population filter, not deliveryRelation -- prDeliversCard is untouched and still wide, as its docblock demands, so H8 / H31 / H35 / H53 still agree about which PR delivers which card and differ only about which binding makes a CARRIER PAIR, a question only H31 asks; both invariant docblocks were updated to say so. Weak bindings are DECLINED, never silently dropped: a weak-bound delivering PR whose carrier differs from the card's still emits a row that names both carriers and the binding it read, says it declined to judge, and prescribes NOTHING (a `tracking` card adds a clause explaining that a ruling anchor stays open by design, so the clearing stroke never arrives); agreement on a weak binding stays silent, as before, because a standing row per tracker per sweep is the disease and not the cure.

C3 control: a closing-keyword binding whose card lacks the gate -> the row STANDS with the unchanged action-shaped sentence. Plus: agreement on a weak binding is clean both ways; a weak-bound card WITHOUT `tracking` still reports the split but without the ruling-anchor clause; an adjudicable split outranks a decline and names only the closing-bound PR; prDeliversCard is pinned still-true on the tracker (the shared relation is NOT narrowed).

    "The dispatch's 裁决 scopes the audible decline to a card carrying `tracking`. Implemented WIDER: the decline fires for ANY non-closing-keyword binding whose carrier disagrees with the card's, and `tracking` adds a clause to the sentence instead of gating the row. Reason: scoping it to `tracking` would have left every non-tracking weak-bound split silently dropped, which is #4690 in H31's own uniform -- a split that was never judged renders identically to agreement, and this is the one row that can tell 「被剥」 from 「从未挂过」. Measured consequence on the live board: none -- no other row changes.",
    "Taking 「binds through the closing keyword」 literally also routes `branch-name`-bound PRs to the declined channel, not only `Part of` ones. No disagreement loses its row (the weak channel reports it descriptively); one existing self-test ('the branch-name fallback delivers a body-silent PR') still passes on typeof but its name would have lied, so it was rewritten in place and a second case pins that it is now the DECLINED sentence.",
    "Extracted `TRACKING_ANCHOR_LABEL = 'tracking'` and pointed the existing `H13_EXEMPT_LABELS` array at it (one token, behaviour-identical, pinned by a new case). Strictly this touches an H13 line; a second literal spelling of the same ruling-anchor state is precisely the drift this file forbids, so the constant is shared rather than duplicated.",
    "The decline is deliberately NOT marked `UNJUDGED_MARKER`. That marker buys trim priority AHEAD of judged rows, and a decline must never sort ahead of a real carrier split inside the same `gate` band; H31's family band already protects it from the trim. Pinned by a self-test case."
