check-half-states: H22 pages a CARD-ONLY stream on the patrol runner and a PR-inclusive one from an agent container, so the file's own cost note, page-ceiling derivation and every hand re-measure describe a population the sweep never reads

Filed by the domain:skills os-dev seat while re-pinning H22's divisor for #17254 (session_01YKEjmbYNvYWJvWGSWx26zK). ⛔ Not that card's work — its file surface is region-declared to the two constants and the self-test pins derived from them, so the prose named below was left byte-identical and is filed here instead. ⛔ No domain:* label: that label is the triage seat's to produce.

The measurement

scripts/pm/check-half-states.mjs pages H22's closed-card window with closedWindowPagePath — GET /repos/{repo}/issues?state=closed&sort=updated&direction=desc&per_page=100&page=N. Two callers issue the byte-identical request and get different populations:

caller	rows per page	PR share
the scheduled patrol runner (`half-state-patrol.yml`, `permissions: contents: read` + `issues: write`)	card-only	0%
a proxied agent container (any seat re-measuring by hand)	issues and pull requests	49.6%

The runner side is measured through the sweep's own numbers rather than by reading its response, because a seat cannot read it:

the 2026-09-11T01:55:32Z run (34552285557, commit 2f8ad091) reports 5 pages, 428 in-window closures, reach 2026-09-07, observed ~141.3/day;
replaying listRecentlyClosedIssues over a container read of the same hour (12 pages, 1,200 rows, captured 2026-09-11T04:22:36Z) gives 9 pages / 426 / ~256.2 per day on the whole stream and 5 pages / 426 / ~139.4 per day on the card-only slice of it;
and 428 in-window closures cannot come out of 5 PR-inclusive pages at all: only ~250 of those 500 rows are cards.

The 2026-09-09 run is the same shape (6 pages, ~167.5/day).

What that makes false, and where

Three statements in the file describe the container's stream while claiming to describe the patrol's. None of them is in #17254's declared surface, so none was touched there:

CLOSED_ISSUE_WINDOW_DAYS's ⚠️ Cost note — 「46% of the rows this stream returns are PULL REQUESTS, filtered out after paging. The horizon is therefore reached in roughly twice the pages a card-only stream would need」. The patrol's stream is the card-only one, so it reaches the horizon in 5 pages, not the ~13 the note derives.
The same docblock's 「check-half-states: re-measure and re-pin MEASURED_CLOSED_ISSUE_UPDATES_PER_DAY (188.3 of 2026-08-31 — the new alarm reads a factor of 2.11 on objectstack) #16419: the divisor below now reads 415.1」 — present tense, and the divisor now reads 139.4.
listRecentlyClosedIssues's own comment — 「the pin this rate is checked against was measured over the RAW stream (400 rows / 0.964 days)」 — which is about the pin it no longer describes.

CLOSED_ISSUE_WINDOW_PAGE_CEILING's derivation (40 pages sized on 「4,000 rows reached 12.8 days … ~312/day averaged over that depth」) was taken on the container stream too, so its real headroom on the runner is about twice what the docblock computes. That direction is safe — it is more headroom, not less — but it is not the number the docblock states.

Why it is a defect and not a note

It is the cause of #17254. The pin it re-pins (415.1, 2026-09-06) was taken from a container read, so it was checked on every run against a population half as dense, and the alarm printed RATE PREMISE DRIFTED at a board that had not moved by anything like the factor quoted. The factor 0.34 the last run printed decomposes into a real ~0.64 slowdown of the stream and a ~0.53 population difference that is not tempo at all. A seat following the docblock's recipe from a container reproduces exactly that, which is what makes this a recipe defect rather than an observation: the measurement instruction, followed correctly, yields the wrong number.

What a fix would decide

whether the recipe states its population (「card-only, as the runner's token returns it」) so a hand re-measure filters PRs out, which is what check-half-states: H22's MEASURED_CLOSED_ISSUE_UPDATES_PER_DAY pin has drifted 2.5x, so every sweep's own coverage sentence is misdescribed by that factor #17254's new record does for the pin alone;
or whether the workflow should declare pull-requests: read so the runner and a container read the same stream, at the cost of roughly doubling H22's page bill;
and, either way, correcting the three statements above and re-deriving the page ceiling's headroom sentence on the population it is actually spent on.

⛔ No claim here that the permission block is the mechanism: it is the reading that fits (the workflow declares contents: read and issues: write and nothing else), but the runner's raw response was never read. The population difference itself is measured.

Dedup — complete enumerations, stated as complete

enumeration	population	pages	hits
`label:domain:skills`, `state=all`	738	8 (page 8 short at 38 rows)	0
every issue created since 2026-09-10T13:44Z	102	2	0

Union 821 unique cards, matched on card-only, PR-inclusive, pull-requests: read, 46% of the rows, population the sweep/patrol, issues: write over titles and bodies. Positive control in the same enumeration: MEASURED_CLOSED_ISSUE_UPDATES_PER_DAY returns #17254, #16419 and #16393, so the zero above is a reading and not a dead channel. ⛔ No free-text search_issues was used.

Triage (skills-lane finding self-triage; routed domain:skills by the triage seat, 5642734402): admitted as class (a) — a measurement recipe that, followed correctly, yields the wrong number. Premise re-checked on origin/main e9efc403 at 2026-09-12T02:16Z: PR #17627 (c1123cf2, #17254) re-pinned MEASURED_CLOSED_ISSUE_UPDATES_PER_DAY to 139.4 from a card-only slice and its docblock now says so, but the three statements this card names are still byte-present — the ⚠️ Cost note 「46% of the rows this stream returns are PULL REQUESTS」 (line 16404), 「#16419: the divisor below now reads 415.1」 (line 16414, present tense against a divisor of 139.4), and listRecentlyClosedIssues's 「RAW stream (400 rows / 0.964 days)」 comment (line 16692); the page-ceiling derivation (line 16448, ~312/day) is container-stream too. Grade: pm:queue · Bug · priority:p2 — Bug because the file's own prose contradicts the constant it now carries, and a seat re-measuring by the recipe reproduces the false RATE PREMISE DRIFTED alarm; p2 because #17627 already stopped the alarm, so what remains is the recipe and the derivation, not a live false page. Scope: rewrite the three statements and the ceiling derivation to name the population each number was taken on (runner = card-only; container = PR-inclusive), keeping the card's own boundary — the population difference is measured, the permission block as its mechanism is ⛔ not claimed (5642734402 asks that this survive the fix); ⛔ no constant moves. Serial: check-half-states.mjs chain — PR #17745 (#17727) currently carries an out-of-face touch on this file that is being justified or dropped; behind it this card becomes the chain head by the total order (p2 Bug ahead of #17564 p3 Bug).

Claim 5643617169 is the dev's identity; branch claude/issue-17626-h22-docblock-population, cut from origin/main at dispatch (8fa3fe63). Deliverable: the four H22 prose sites say which POPULATION each number was measured on (the patrol runner's card-only stream vs a proxied container's PR-inclusive stream, 49.6% PRs) and give the re-measure recipe that reproduces the patrol's own numbers (the card-only slice of a container read: 5 pages / ~426 / ~139.4 per day on 2026-09-11), keeping PR #17627's constant 139.4 and the ceiling 40 untouched and stating the ceiling's real runner-side headroom (about twice the docblock's derivation) as a note, not a change; the card's boundary preserved verbatim in spirit — the population difference is MEASURED, the runner's permission block as its mechanism is NOT claimed. ⛔ Prose only in that file.

The Cost note under CLOSED_ISSUE_WINDOW_DAYS now labels its 46% as a container reading, quotes the runner side from the sweep's own numbers (run 34552285557, 2026-09-11T01:55:32Z, commit 2f8ad091: 5 pages / 428 in-window closures / reach 2026-09-07, and 428 closures cannot come out of 5 PR-inclusive pages since only ~250 of those 500 rows would be cards), and carries the re-measure RECIPE once: filter pull requests out of every page BEFORE counting or rating, and quote the card-only slice (5 pages / 426 / ~139.4 per day, against 9 pages / 426 / ~256.2 per day on the whole stream).

Implemented-by: os-dev subagent on claude/issue-17626-h22-docblock-population (claim 5643617169; build tier opus; mode:subagent; report on this card). Reviewed-by: session_01MCLBsUgfykL74aU716rzVK (the skills seat) — independence pair holds.
The four H22 prose sites (16638 / 16648 / 16682 / 16926 on 8fa3fe63, confirmed byte-present before the edit) now name the POPULATION each number was taken on: the ⚠️ Cost note labels its 46% as a container reading, quotes the runner side from the sweep's own numbers (run 34552285557, 2026-09-11T01:55:32Z, commit 2f8ad091: 5 pages / 428 / reach 2026-09-07; 428 closures cannot come out of 5 PR-inclusive pages) and carries the RE-MEASURE RECIPE once (filter pull requests out of every page BEFORE counting or rating; the card-only slice reads 5 pages / 426 / ~139.4 per day against 9 / 426 / ~256.2 on the whole stream); the present-tense 「415.1」 sentence becomes history against the 139.4 the file carries; the page-ceiling derivation gains a population note stating the runner-side headroom as about twice (~25 days vs 12.8) — a note, not a change; listRecentlyClosedIssues's comment states the pin's population. The card's boundary is carried in those words: the difference is MEASURED, the runner's permission block as mechanism is NOT claimed. No constant moved (139.4 and 40 stand), no H-row, no self-test change.
Seat's own readings: the diff (+70/−21, one file) touches NO executable line — every added or removed line is a comment line (grep on the PR diff); card-only appears 7 times; raw NUL bytes on the head blob = 0; body first line Fixes #17626, no other closing keyword; CI on 034c09ac at 05:38Z 21 success / 10 skipped / Lint & Repo Gates in progress.
Evidence: 40 derived gates all exit 0, reconciled with --ran (0 NOT-MEASURED); half-states self-test 3656 before = 3656 after (the before-count run on the 8fa3fe63 copy of the file); check-nul-bytes OK over 8451 files; the comment-mask corpus sweep (6640 files, 0 disagree) proves the rewritten blocks still parse as comments; --pair 17793 exit 0; no ablation applies to comment bytes and the report says so rather than inventing one.
Out-of-scope notes carried, none filed: MEASURED_CLOSED_ISSUE_UPDATES_PER_DAY's own docblock (PR fix(pm): re-pin H22 closed-issue update rate from a card-only measurement of the stream the patrol actually pages #17627) names the runner token's scopes inside its population paragraph — labelled 「Measured, not inferred」, so not a mechanism claim; the card's second route (declaring pull-requests: read on the patrol workflow so both callers read one stream) is untouched and its page-bill cost unmeasured — a successor card if a seat wants it; the PR body carries two footers (the platform's PATCH /pulls block, not re-sent per the readings table), so the landed squash message will too — cosmetic.
Landing plan: ready flip once Lint & Repo Gates reads success and every check on the head is green or superseded; auto-merge SQUASH; landing record; pm:dispatched + assignee cleared with read-back; chain: check-half-states.mjs → [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 #17564.
