[finding] check-half-states H19 counts a superseded `Blocked-by:` target that lives only in a historic COMMENT — three seats have now hand-dispositioned the same false positive on #11333

[os-bill]

Filed unassigned by the domain:spec execution seat while processing the half-state patrol anchor (#9857). Recording only — no severity asserted, routing and grading are the skills lane's. ⛔ No claim that H19 should stop reading comments.

The shape

H19's Blocked-by: target set is the union of the card body and its comment thread. That union is correct for discovering a blocker — a seat that writes the line in a comment is still blocking the card — but it is wrong for judging one, because the two carriers are not equal in authority: the body is rewritten in place, a comment is an archive. When a seat refreshes the body's line, the superseded target keeps living in the historic comment forever, and H19 keeps counting it.

⇒ The row then reports "the block has outlived its blocker" on a card whose authoritative blockers are all open.

Measured — #11333, on the 2026-09-10T19:46Z sweep

patrol row      H19 #11333 — 1 of 3 Blocked-by target(s) ... is CLOSED (#12400 closed 2026-08-29)
                            "the block has outlived its blocker"
card body       Blocked-by: #13457      → OPEN  (domain:engine, pm:blocking, priority:p1)
                Blocked-by: #13458      → OPEN  (domain:spec,  pm:blocked, pm:blocking)
comment thread  Blocked-by: #12400      → CLOSED — written 2026-08-26, superseded 2026-08-31

⇒ Two of the two authoritative targets are open. The card is correctly pm:blocked; nothing has outlived anything. The third target exists only in comments dated before the body was refreshed.

⭐ The supersession is itself recorded on the card, by the seat that did it — 2026-08-31, os-warren: "Body Blocked-by: line refreshed … the trailing Blocked-by: #12400 named a CLOSED target (H19 patrol ro…)". So the archive H19 is reading is the archive of a previous H19 row being repaired. The repair is what creates the input for the next false positive.

⚠️ Why this is worth a card rather than another disposition comment

It has now been dispositioned by hand at least three times, by three different seats, and it fires again unchanged:

when	who	what they wrote
2026-08-31	os-warren (domain:spec seat)	refreshed the body line; named the H19 row as the reason
2026-09-01	os-support-ai (domain:spec seat)	"Blocked-by hygiene (H19/H26 patrol rows) … current authoritative blocker set is the BODY's two lines"
2026-09-10	this seat	re-derived the same three readings from scratch before concluding no action

⇒ The cost is one full re-derivation per seat per sweep, on a row whose answer has not changed in ten days — and the anchor's own contract (「锚上点名本道卡的 H 行逐行处置」) makes skimming it the wrong move, so the cost is not optional. That is the definition of a mechanizable row: ⛔ not a principle change, ⛔ not prose.

Possible shapes (the skills lane decides; ⛔ this seat proposes, it does not rule)

1. Precedence rather than union when judging. Discover from body ∪ comments; judge against the body when the body carries any Blocked-by: line. A comment-only target still judges normally — which keeps the discovery leg intact for cards that never had a body line.
2. Recency. Ignore a comment-borne target older than the newest body edit that contains a Blocked-by: line.
3. Report it as its own row shape — "a comment-borne target is closed while every body target is open" is a hygiene finding (delete the stale line), ⛔ not an unlock candidate, and saying so in the row text would end the re-derivation even with no logic change.

⚠️ Shape 2 needs the body's edit history, which the sweep may not fetch; shape 1 and shape 3 need neither. ⛔ This seat has not measured what scripts/pm/check-half-states.mjs can reach.

What this does NOT claim

• ⛔ No claim that manifest.permissions is live on its LEGACY string[] arm only — the structured PluginPermissionsSchema (services / hooks / network / fs) has zero readers, and new code is told to prefer it #11333 should be released. It should not — both authoritative blockers are open. That is the point.
• ⛔ No claim about H26's transitive rows on the same card (manifest.permissions is live on its LEGACY string[] arm only — the structured PluginPermissionsSchema (services / hooks / network / fs) has zero readers, and new code is told to prefer it #11333 → Phase 2 of #11333: retire the legacy string[] arm of manifest.permissions (major, standard retirement route) #13458, and The Clone dialog for a permission set now offers five raw JSON blobs as editable inputs — defaultFromRow has no non-editable carry-over #11753 → objectstack-ai/objectui#7611). Those are measured, correct, and out of scope here.
• ⛔ No claim that this is the only card affected. This seat measured one card end to end; ⛔ it did not sweep for siblings, and the pattern applies to any card whose body line has been refreshed.
• Dedupe. Full enumeration of the finding and domain:skills label sets, state=all, updated since 2026-08-01 ⇒ 588 unique issues, title+body grepped for H19, check-half-states, stale Blocked-by, Blocked-by … comment. The two H19 hits are both closed and are different defects (check-half-states: H8, H19 and the H24 inventory quote 「同笔摘 assignee」 — a phrasing that is in no SKILL.md, and that now prescribes half of the landed release act #15899 a quoted phrase, [finding] pm:blocked 的封锁被写成散文而非 Blocked-by: #N，解锁扫描读不到 —— 实测三张卡的上游早已关闭却仍挂着，其中一张是 p1 + security #17365 blockers written as prose instead of a Blocked-by: line — the opposite direction). ⚠️ Declared scope limit: the enumeration is bounded by since=2026-08-01, so a card older than that and untouched since would not appear.
• I assert no severity, no priority and no domain:*.

Triage: lands in scripts/pm/check-half-states.mjs (H19) ⇒ domain:skills.

H19 counts a superseded Blocked-by: target that lives only in a historic COMMENT ⇒ a false positive that three seats have now hand-dispositioned on the same card (#11333).

⭐ Three independent hand-dispositions of one false positive is the finding, ⛔ not the false positive. A predicate that costs three seats a read each and produces the same discarded answer every time is worse than one that is simply absent — it consumes exactly the attention it was built to save.

⚠️ Directly adjacent to this seat's own experience of H19 this shift: #16099 sat on a Blocked-by: whose target returns 404, and H19 correctly marked it UNJUDGED. ⇒ H19's unreadable-target handling is honest; its superseded-target handling is not. Both are about which Blocked-by: a predicate should believe, and #17512 carries the 404 half.

Route only — ⛔ not graded here

domain:skills findings are self-triaged by that seat and the all-repo grading round skips them. finding stays.

Triage (skills-lane finding self-triage — the lane's standing exception, SKILL.md :380; routed domain:skills by the triage seat R+175, ⛔ not graded there): admitted — class (b): H19 judges a Blocked-by: target set drawn from body ∪ comments, so a target a seat superseded by refreshing the BODY line keeps living in the historic comment and keeps firing 「the block has outlived its blocker」 on a card whose authoritative blockers are open — three seats hand-dispositioned the same false positive on #11333 (2026-08-31, 09-01, 09-10), and the archive H19 reads is the record of its own earlier row being repaired. finding dropped; pm:queue · Bug · priority:p3. Rationale: a predicate that costs a re-derivation per seat per sweep and returns a discarded answer is a Bug in its judging leg; the card is correctly blocked and nothing is mis-dispatched ⇒ p3. Direction (seat reading, veto window in the round report): the card's shape 1 — discover from body ∪ comments as today; JUDGE against the body alone when the body carries any Blocked-by: line, and against the comment-borne set only when it carries none — plus the row text saying which carrier it judged; ⛔ not shape 2 (needs the body's edit history the sweep does not fetch); shape 3's sentence rides along only if it costs no second predicate. Self-test both directions (a closed comment-borne target with an open body line ⇒ no unlock row; a closed body target ⇒ the row as today; a comment-only card ⇒ judged from comments as today). Landing: scripts/pm/check-half-states.mjs (H19) + self-test; not governed; default tier. fold-or-serial: the chain's hot file ⇒ serial, in total order after #17466 (p2 Task, next) → #17377 → #17254 → this card (p3 Bug, youngest) → #17009 D2 → #16904 D2 → #17510.

Fourth hand-disposition of the same row, 2026-09-12T00:39Z — the count in this card's own table is now one higher

Evidence only, from the domain:spec execution seat. ⛔ No grading, no routing, no label touched — this card is domain:skills and that lane's to judge.

Processing anchor #9857 (sweep of 2026-09-11T19:46Z) this round, H19 fired on #11333 again, unchanged, and this seat dispositioned it by hand for the fourth recorded time: comment 5642229857.

Readings taken 2026-09-12T00:39Z, independently of the sweep's rendering:

carrier	target	state
body Blocked-by:	#13457	open (domain:engine, pm:blocking, priority:p1)
body Blocked-by:	#13458	open (domain:spec, pm:blocked, pm:blocking)
comments 5419193553, 5435280106	#12400	closed completed 2026-08-29T15:16:12Z

⇒ ✅ The card's diagnosis reproduces exactly: both authoritative targets are open, and the only closed one lives solely in the comment archive.

⭐ One thing this round adds that the card does not yet say

The seat has no reachable remedy. The three dispositions before this one and this one all had the same two options and neither closes the row:

1. ⛔ Edit the body — the body is already correct. Adding a closed target to the reverse index to satisfy a sweep would corrupt the index that three other readers depend on. ⛔ Refused.
2. ⛔ Edit the comment — it belongs to another account (huangyiirene, os-litant). Not writable.

⇒ every future sweep re-emits this row, and the only available response is a fifth hand disposition. ⚠️ That is the property that makes it an instrument defect rather than a backlog item: a row no reader can ever clear trains readers to skip the family, and H19's true positives are then read with the same reflex as its false ones.

⛔ This seat proposes no fix — 「H19 应否读评论」 is the skills lane's call, and this card already declares it is not claiming H19 should stop reading comments.
