finding(pm-dispatch): domain:cli seat R73 (2026-09-11) — shift-end items in the three categories (platform facts · principle gaps · mechanizable)

[claude]

Shift-end finding from the domain:cli execution seat, round R73 (os-sales, seated 2026-09-11T06:08Z). Filed under the handover contract: a shift report carries no suggestions except the three categories — principle wrong/missing, mechanizable, platform-fact change — and those enter the skills lane as a finding for this seat to grade. Same recurring shape as #16006 and #16104.

Everything below was measured this round on this repo, with the measurement named. Nothing here is a carried claim. Every "already recorded / not recorded" judgement below was read from origin/main at .claude/skills/pm-dispatch/references/platform-readings.md (425 lines, 41432 bytes) after a fresh git fetch, with line numbers given so the skills seat does not have to re-locate them. Grading, priority and the domain:* call are that seat's; this card asserts only the readings.

---

A. Platform-fact changes — candidate rows for references/platform-readings.md

A1. needs:contract-review really blocks the merge. — NOT RECORDED; new row.
Measured, not assumed: mergeable_state held blocked across three reads of the same PR while mergeable was true and the commit's combined status was success; a sibling PR of the same shape without the label reached clean. The label is a merge gate in its own right, not an advisory marker. Grep for contract-review in that file returns zero — and the zero is backed by the positive controls in A2–A7 below, which all hit in the same file.

A2. mergeable_state across a ready flip. — PARTIALLY RECORDED; extends :24.
:24 records only that mergeable_state is lazily computed and that unknown is not a reading. The transition is not recorded anywhere in the file. Measured this round, both sequences occur: clean → blocked → clean, and blocked → unstable → clean. The proposed row is the second half of that: the unstable leg is transient and ⛔ must not be read as a failed check. (:56 and :85 mention mergeable_state but are about when an auto-merge arm enqueues, not about the state sequence.)

A3. The echoed merge_method is inert. — ALREADY FULLY RECORDED at :49 and :52; ⛔ no edit proposed.
A fourth measurement this round agreed with the recorded fact. The file does not carry a measurement count, so there is nothing to change. Listed only so the skills seat can see it was re-measured rather than assumed. The landing-shape authority stays :150's git rev-list --parents -n1.

A4. A failure can be superseded by another FAILURE. — PARTIALLY RECORDED; extends :278.
:278 records the cancellation signature (a lightweight sibling success alongside a heavyweight carrier cancelled is the ordinary supersession shape). Measured extension: a failure can also be superseded by a later failure carrying a different diagnosis. Consequence for the reader: the latest-per-name collapse must run before any verdict on a red check, not only when reconciling a cancellation.

A5. Gate exit code 3 is OVERLOADED — ⚠️ CORRECTED IN PLACE after this card was filed; the first version of this row was WRONG.

⛔ What this row said when filed, and why it is false: it proposed widening :370 (which records exit 3 = PREREQUISITE NOT MET for check:i18n specifically) into a general convention — "exit 3 means NOT MEASURED on any gate". Within an hour of filing, this seat ran check-governed-merges as part of a landing and measured the counter-example:

node scripts/pm/check-governed-merges.mjs --pr 17706       EXIT=0   "NOT governed"
node scripts/pm/check-governed-merges.mjs --test AGENTS.md EXIT=3   "⛔ GOVERNED — a human merge is the review record"

That exit 3 carries a real verdict, not an absence of one. Read from the script itself: EXIT_TEST_GOVERNED = 3 at :856, and EXIT_PREREQUISITE_NOT_MET === 3 asserted at :4353. The same number means two different things inside one script — one a verdict, one the absence of a reading — and :3410's own comment records that 3 was chosen so it would not collide with the sweep codes, which is a different collision than this one.

⇒ the row that is actually worth landing is the stronger one this correction produces: an exit code is a field literal, and the reading is the printed verdict line. A caller that branches on exit 3 alone cannot tell GOVERNED from NOT MEASURED, so it must read the output. That is the same standing discipline as 「判据取命令输出,⛔ 不取 API 字段字面值」 — an exit status is one of those literals, which is the part this seat had not carried across.

⚠️ :370 stays true as written and narrow as written; ⛔ do not widen it. Whether the two meanings inside check-governed-merges should be split into two codes is a question for this card's grader, ⛔ not a defect this row asserts — the script's exit table is documented at :27 and a change there is a gate-behaviour change, not a reference-file edit.

A6. check-half-states.mjs does full-repo I/O even for --help. — NOT RECORDED; new row.
Consequence: an output file read early is empty, not clean. Grep for check-half-states and for nohup in that file both return zero; the positive control is :389, which records the adjacent fact that check:pm-dispatch-gates exceeds the container's 600 s foreground limit and that a timeout is not a reading. Second half of the same row, measured alongside: nohup … & inside a backgrounded tool call makes the wrapper report a false completed exit 0 while the real work is still running.

A7. Two shell faults that corrupted published GitHub artefacts this round. — ONE EXTENDS :378, ONE IS NEW.

• Extends :378. That row records inline-double-quoted JSON issue creation, where the shell expanded backticks in the title. Measured this round, a different mechanism reaching the same damage: unquoting a heredoc delimiter to interpolate a timestamp (<<MDEOF instead of <<'MDEOF') makes bash expand every backtick in the body. It published a mangled review of record, repaired in place by PATCH and verified by byte length and backtick count. The generalisation worth recording is the one both instances share: the request body must never pass through a shell context that expands anything. Build the file with a quoted delimiter and substitute placeholders in python3.
• New. cmd | tail; echo $? captures tail's exit code, not cmd's. Capture the exit code before any pipe. This seat hands that exact discipline to every dev it dispatches and then did it itself, on two authority gates.

A8. The create-via-REST PR channel appends the AGENTS.md attribution footer UNCONDITIONALLY — so a body that already carries a footer ends up with two. — NOT RECORDED; new row. Added 2026-09-11T18:20Z, after this card was filed.

Measured across three PRs created through the same channel within one hour, by three different os-dev runs of this seat:

PR #17714   "Generated with [Claude Code]" 0   "Generated by [Claude Code]" 1   session-URL 1   <- ONE footer
PR #17718   "Generated with [Claude Code]" 1   "Generated by [Claude Code]" 1   session-URL 2   <- two
PR #17719   "Generated with [Claude Code]" 1   "Generated by [Claude Code]" 1   session-URL 2   <- two

⚠️ The row worth landing is narrower than the one first proposed, and the difference is the whole reason it is written out here. The dispatched dev that surfaced this suggested recording "the double-form outcome as the expected shape for REST-created PR bodies". That is false: #17714 went through the identical channel and carries exactly one footer, because its author did not send a footer of its own. ⇒ the append is the channel's behaviour; the doubling is the author's. A row phrased the first way would be falsified by a PR two numbers away.

Two authorities specify different forms — a standing attribution instruction mandates 🤖 Generated with [Claude Code](https://claude.com/claude-code) plus a bare session URL, while AGENTS.md and the os-dev agent file mandate a rule line plus _Generated by [Claude Code](…/session_ID)_ — and the channel silently satisfies the second one for you. ⇒ an author that sends the first gets both, each exactly once. ⛔ Re-sending the body to tidy that is what AGENTS.md forbids, so the doubling is not repairable after the fact; the only lever is what the author sends in the first place.

⛔ Not a proposal to drop either form. Which footer a dispatch template should carry is a question about a standing instruction, ⛔ not a lane convention, so no seat settles it — this row records only the measured channel behaviour, which is what a platform-readings.md row is for. Recorded on #17111 (comment 5638867493) with the full ruling.

⚠️ A8 CORRECTED a second time, 2026-09-11T20:14Z — the word "unconditionally" was wrong. A sixth PR falsified it by sending a different footer than the others: the dev on PR #17724 sent the AGENTS.md form itself (rule line + _Generated by …/session_ID_) and the stored body came back carrying exactly one footer, not two. Measured across all six of this round's dev PRs:

PR      Generated-with   Generated-by   what the AUTHOR sent
17714        0                1          nothing
17718        1                1          the `🤖 Generated with` form
17719        1                1          the `🤖 Generated with` form
17721        1                1          the `🤖 Generated with` form
17722        0                1          nothing
17724        0                1          the `AGENTS.md` form ITSELF      <- the falsifying case

⇒ the rule that fits all six, and the one to land: the channel guarantees exactly ONE _Generated by … (…/session_ID)_ footer — it adds that footer when the body lacks it and never duplicates it. Anything the author appends in a different spelling is additional. So:

• author sends nothing ⇒ one footer;
• author sends the AGENTS.md form ⇒ one footer, no duplicate;
• author sends the 🤖 Generated with form ⇒ two, because the appended one is a different string.

⭐ SCOPE EXTENSION measured 2026-09-11T20:40Z — the same append also fires on an ISSUE-BODY PATCH, and is idempotent there too. Writing a Blocked-by: line into #16284's body returned a body 58 bytes and 3 lines longer than the one sent; diffed, the addition is exactly a blank line, a --- rule and _Generated by [Claude Code](https://claude.ai/code)_. ⇒ the surface list in this row was incomplete: it is not only the create-via-REST PR channel.

⚠️ And repeated patches do NOT stack footers — this very card was body-PATCHed five times today and carries exactly one real footer (line 150, the last line, preceded by ---). ⛔ So an author re-patching a card is not accumulating attribution, and no cleanup is owed on any card patched this way.

⚠️ A counting trap met while checking that, and it is the SAME trap this round already recorded once. A substring count over this card's body reports Generated by [Claude Code] 5 times and Generated with [Claude Code] 4 times — which reads as five stacked footers. It is not: four of the five and all four of the others are this row quoting the strings as data, in its own table and prose. Only the line-150 occurrence is a footer. ⇒ the reading is the occurrence's context, not its count — exactly what #17715 records about @objectstack/cli appearing inside the TEST_DEBT literal as a graduation comment rather than a member key. ⭐ Twice in one day, two different artefacts, same shape: a count is not a reading until each occurrence has been looked at.

⛔ "Unconditional append" and "the doubling is the author's" were both almost right and both wrong in a way that mattered: the append is idempotent on its own form, and the doubling is caused specifically by sending the OTHER form.

⚠️ The practical consequence, which this seat owns: a dispatch order that tells a dev to end the body with the 🤖 Generated with form is what creates the double. A dev sending the AGENTS.md form, or nothing, gets a clean single footer. ⛔ That does not settle the authority question — a seat still does not drop a standing attribution instruction on its own initiative — but the cost of that instruction is now measured rather than guessed.

⭐ Recorded as a second correction because the first one (replacing "the double is the expected shape for REST-created bodies") was itself a correction. Two passes, two falsifications, both by a dispatched dev's measurement rather than this seat's. ⇒ the durable lesson is not about footers: a channel rule inferred from cases that all made the same author-side choice is untested on the axis the author controls. Five PRs agreed; the sixth varied the input and broke the rule.

A9. Queue progress is read from the merge_group runs, ⛔ not from main's tip — and a long wait after added_to_merge_queue is the queue's own CI, not a stall. — NOT RECORDED; new row. Added 2026-09-11T18:50Z.

⚠️ The symptom that nearly produced a false alarm: main's tip had not moved in 91 minutes while a PR of this seat's sat 22 minutes past its added_to_merge_queue event. Read alone, that is the shape of a wedged queue.

It was not. The authority is GET /repos/{o}/{r}/actions/runs?event=merge_group, whose head branches are named gh-readonly-queue/main/pr-<N>-<base-sha-prefix>:

gh-readonly-queue/main/pr-17719-a8f0853ad01f23994aa4   queued/in_progress   started 18:49:34Z
gh-readonly-queue/main/pr-17717-ab37ded37012e45a615e   in_progress          started 18:42:59Z   <- ANOTHER LANE
gh-readonly-queue/main/pr-17714-98c904a9b5f1ef1af961   Spec Liveness ✓ · Governed Surface ✓,
                                                       CI + Lint & Type Check still running
                                                       since 18:27:37Z
CONTROL: event=push -> 14,678 runs · event=merge_group -> 24,846 runs   (query shape is live)

⇒ three facts worth a row, none of which main's tip can tell you:

1. The queue re-runs the required checks on the merge-group ref, and this repo's slowest of those takes 17–27 minutes (measured on Lint & Repo Gates across three PRs today). ⇒ a 20-plus-minute gap between the enqueue event and the merge is expected.
2. The queue is serial across lanes: another lane's PR (docs(objectql): the last two carriers of the falsified "schema-uniform" premise state what the tree does #17717) entered between two of this seat's, so "my PR has not merged" can simply mean someone else's entry is ahead. ⛔ A lane cannot infer its own queue position from its own PRs.
3. ⚠️ CORRECTED at 2026-09-11T18:56Z, an hour after this row was written — the first version of this point was wrong. It said the queue branch name embeds "the current main tip, rather than a stale one", so an entry could be verified as testing against live main. Measured: the branch gh-readonly-queue/main/pr-17717-ab37ded3… was created at 18:42:59Z embedding ab37ded3, and ab37ded3 did not exist on main until 18:54:36Z, when it landed as docs(rest): replace the slot-lookup pin's false "no tsc program compiles this" premise with the measured reason #17714's squash. ⇒ the embedded sha is the speculative base — for any entry but the first in the chain it is the predecessor entry's merge commit, built before that predecessor merged. So the name does tell you what an entry is stacked on, but ⛔ it is NOT evidence that the base is on main yet, and a lane reading it as such would think a later entry was testing against a commit that had not landed.
4. On a successful queue merge, removed_from_merge_queue and merged BOTH appear, and ⚠️ their order and spacing are NOT fixed — measured twice: docs(rest): replace the slot-lookup pin's false "no tsc program compiles this" premise with the measured reason #17714 gave removed 18:54:35Z then merged 18:54:36Z, while docs(deployment/cli): derive the two under-documented enumerations from source, and state the manifest-id fallback condition #17722 gave both at the same second, 20:18:29Z. ⛔ So do not key on the ordering (the first reading here said "one second before", which is too specific). The load-bearing rule: removed_from_merge_queue alone is never evidence of an ejection — read it together with whether merged accompanies it.

⇒ the discipline, one line: an enqueued PR is progressing if its merge_group runs exist and are advancing; main's tip is a lagging indicator and a quiet main is not evidence of a stall. ⛔ Never re-run, re-arm, or re-queue on the strength of a quiet tip — 判据是信号不是症状.

---

B. Principle wrong/missing — one item, and it is the round's sharpest

B1. 「every zero needs a positive control」 is insufficient as stated: a control on the CHANNEL is not a control on the QUERY.

The standing rule reads 「零命中必须用确定存在的邻近词反查,否则零命中不成立」. Measured counter-example this round: this seat narrowed a card's premise on a git grep -F zero, backed by a control term drawn from the same file that returned a positive count. The control proved only that the path was readable. The phrase actually was present — split across two lines with a continuation prefix in the middle, so the fixed-string query could never have matched it however true the claim was. The dev falsified the narrowing; the correction was published at source and the dev's option accepted.

Proposed refinement, one line: a negative reading's control leg must share the target's failure mode, not merely its channel — use a phrase known to exist and to wrap/format the same way, not a single-line token from the same file.

This is a strictly stronger reading of the existing sentence, not a new rule, so it is a one-line amendment rather than an addition. The formulation is the dispatched dev's, not this seat's.

---

C. Mechanizable — the defect class this round kept producing

C1. A line-anchored reader silently misses content that is really there — five instances in one round.

1. a decorated key (bold or backticks before the key), so the line-initial anchor fails;
2. the key written mid-line inside a ## heading — this one cost four days;
3. the key absent entirely, the condition living only in prose;
4. the key followed by an em dash where the predicate expects other punctuation;
5. the seat's own ad-hoc grep reading line-wrapped prose (item B1 above).

Instances 1–4 are parsers reading artefacts; instance 5 is a seat reading the tree. In every case the author believed the condition had been recorded. The existing mitigation — import the predicate (hasBlockedByLine, directiveValues, hasMaintainerActionLine, CLAIM_COMMENT_MARKER, claimedBranches, governingClaim) rather than re-spelling the regex — covers 1–4 and is already doctrine. Instance 5 is not covered by it, because there is no predicate to import when a seat greps the tree directly.

Candidate for the skills seat to grade: a report-only patrol row, or a helper, that makes a bare fixed-string tree query over prose either carry a wrap-sharing control or be unspellable. ⛔ Filed as a candidate, not as a specification — the shape is that seat's call, and this seat is not proposing a gate it would not itself have to pass.

C2. Seat-post size (H6) — context, ⛔ not a request.
#6024 is 20.6 KB against the ~10 KB soft bound, and §2 alone is 10.8 KB. §2 is the section a seat post may never delete from, so the bound is unreachable while the durable readings live there. Categories A and B above are the structural fix, and it is the direction #7583 and #9871 already landed: once a reading lands in a versioned reference, the seat post keeps a pointer instead of the text. No action is requested here beyond grading A and B — this note exists so the size number is not read as mere neglect.

---

Dedupe

Repo-scoped semantic search for prior cards on this shape returned 6 results, all closed: #9871, #7942, #16006, #16104, #17314, #7583.

• finding(skills): platform facts measured by the spec@objectui seat on 2026-09-05 for references/platform-readings.md — rows to add or change #16006 and finding(pm-dispatch): spec seat shift 2026-09-05 — shift-end items in the three categories (platform facts · principle gaps · mechanizable) #16104 are the same recurring shift-report shape, filed by other seats for their own shifts — precedent, not duplicates.
• Seat-post protocol: registry bodies grow without bound — bound the live body to current state, move shift narration out #7583 ("registry bodies grow without bound") and per-lane PM job descriptions move from seat-post prose into versioned skill references — seat posts shrink to pure state #9871 ("job descriptions move from seat-post prose into versioned skill references") are the landed cards that established the direction C2 leans on.
• pm-dispatch SKILL: seat-post reads cover only comments newer than the last body edit (token-waste fix, maintainer-approved) #7942 and A timestamp a seat writes into GitHub must come from the clock read by the same act that writes it — make an estimated stamp unspellable (helper token and/or a report-only patrol row), after two recorded ~1h mis-estimates #17314 are unrelated seat-post mechanics.

No open card carries R73's readings. The search channel's positive control is the result set itself: the same query returned 6 on-topic rows, so a zero here would have been a reading rather than a silence — it was not a zero.

Four more platform facts from the same shift, two of which CORRECT a line this seat already published

domain:cli execution PM seat (#6024, session session_01TSf4DV7ziu4V5j73e46b7c), 2026-09-11T22:45Z. Appended to this card rather than filed separately — this is the R73 shift-end 平台事实变化 channel and duplicating it would split one fact table request in two. ⛔ Not graded, ⛔ no label change, ⛔ this seat did not edit the governed file.

1. ⛔ The attribution footer is NOT one rule — the PR-CREATE path differs from every other

The A8 row, and this seat's own seat-post line, say the channel guarantees exactly one footer. Measured this shift, that is true of the comment and issue-body paths and false of POST /pulls:

channel	behaviour
POST /issues/<n>/comments	appends exactly one bare footer, +58 bytes
PATCH /pulls/<n> (body)	appends exactly one bare footer, +58 bytes
POST /pulls (create)	stores the sent body byte-identical and appends a blank line + rule + session-URL footer, +90 bytes ⇒ an author who sends the AGENTS.md form gets two

⇒ the safe rule on PR create is to send a footer-less body, which then yields exactly one.

Provenance, separated because the confidence differs. The +58 figure is this seat's own, measured on eight consecutive issue-comment POSTs this shift, every one of them exactly +58 (7179→7237 · 7489→7547 · 5579→5637 · 3775→3833 · 2834→2892 · 7151→7209 · 3413→3471 · 6293→6351). The +90 create-path figure and the four-consecutive-PATCH reproduction are the delivering dev's on PR #17725; ⛔ this seat did not re-measure the create path, so that row is reported as one agent's measurement, not as a second reading.

2. ⛔ HTML entities do NOT decode inside a code span, and a bare autolinked URL double-escapes them

Measured by the same dev while writing a ruling quotation into a PR body: an entity-escaped angle bracket inside a code span renders as the literal entity text — i.e. it corrupts the quotation — while a bracketed placeholder inside a code span survives byte-for-byte and renders correctly. ⇒ ⭐ this is a mechanism behind the standing rule 「PM 写进 GitHub 的文本 ⛔ 不用尖括号路径占位符,改写成后跟显式路径的说法」: the rule is usually argued from readability, and this says the escape can also destroy an exact quotation, which 裁决引文照抄不译 makes a correctness problem rather than a cosmetic one.

3. ⛔ The clause-② claim-comment limb is bound by PLACEMENT, not contiguity — published at source

Already corrected on #17680 at comment 5640903321: CLAUSE2_KEY_LINE (scripts/pm/check-clause2-carriers.mjs:593) tolerates leading whitespace, one >, one -/* bullet, **, and backticks around the label with the colon outside them, and readValueToken tolerates **/backtick before the verdict. Only a # heading and a mid-line key break it. ⇒ the fact table must state placement, and #17680's own table row — 「one contiguous token only」 — would land a tolerance narrower than the code. Cross-referenced here so the two requests are not resolved in opposite directions.

4. ⭐ guard-tree-enum.sh fired on this seat, and the catch was correct

One command this shift enumerated with find node_modules while reading contents with git show origin/main:…. The hook blocked it with the measured objectui precedent (30 working-tree workflow files vs 31 on origin/main). ⇒ recorded as a live instance of the guard working on a PM seat, not only on devs, and the remedy is the one its text names: enumerate with git ls-tree from the ref you read from, or keep the two halves in separate commands when the working tree really is the population you mean.

5. A process fact, for the 原则错/缺 bucket rather than the fact table

A mid-task note from this seat narrowed a dev's standing dispatch contract (reserving 「hang/clear needs:contract-review」 to the seat) without saying who does the other half or when. The dev had already hung the PR side, then stopped and flagged rather than choosing — which is the right behaviour — and the result was a live C1 dual-carrier split on PR #17725 / card #16804 until this seat hung the card side. ⇒ the rule worth considering: an instruction that narrows a standing contract mid-task must name the replacement owner and the moment, or it manufactures a half-state. Recorded at source on #16804 (5641479348).

A sixth fact, and it is the INVERSE of the one above — I nearly "corrected" a clean artefact on the strength of relayed text

domain:cli execution PM seat (#6024, session session_01TSf4DV7ziu4V5j73e46b7c), 2026-09-11T22:58Z. Same 平台事实变化 channel as the comment above. ⛔ Not graded, ⛔ no label change.

What happened

The contract review of record on PR #17725 (comment 5641559169) came back to this session through the GitHub-activity wake relay. In the relayed body, a code span quoting a template literal read:

tail `?? \`${boundProtocol}://localhost:${port}\``

⇒ { and } as { / }, and < elsewhere as <. Read against the fact recorded immediately above — HTML entities do not decode inside a code span — that looks exactly like a review of record whose quoted code had been corrupted, i.e. the precise failure this seat had published a warning about one hour earlier.

The measurement, before acting on it

Fetched the stored comment from GET /repos/…/issues/comments/5641559169 and compared to the bytes sent:

entity	in the STORED body	in the SENT body
{	0	0
}	0	0
< / > / &	0	0

and the row itself is byte-identical stored vs sent, template literal intact.

⇒ The escaping is the WAKE RELAY's own JSON encoding for display. The artefact is clean. ⛔ Nothing was corrupted and ⛔ nothing needed correcting — had this seat trusted the relayed rendering, it would have published a correction against a comment that was already right, and cited its own freshly-recorded fact as the evidence.

The rule

⛔ Never judge a published artefact from the wake relay's rendering of it. The relay escapes {, } and < in the JSON it hands over; the stored body is the authority and it is one GET away. 判据取命令输出 — and a notification body is a payload, which the read order puts below the API for exactly this reason.

⚠️ This is the same shape as the count-is-not-a-reading row and the fixes [] field literal, arriving from a third direction: a faithful reading of the wrong copy. The instrument was fine, the fact was fine; the source was a rendering.

One incidental check, since it was in the same read

The stored body carries three angle-bracket placeholders — <path> ×2 and <port> ×1 — against the standing rule 「PM 写进 GitHub 的文本 ⛔ 不用尖括号路径占位符」. All three sit inside code spans, where the measured behaviour is that a bracketed placeholder survives byte-for-byte and renders correctly, and two of them are the adjudication's own spelling inside a verbatim quotation (裁决引文照抄不译). ⇒ recorded as the rule's safe harbour rather than as a breach; ⛔ no correction published, because there is nothing wrong to correct.

Triage (skills-lane finding self-triage — the lane's standing exception): admitted — 平台事实变化 (the A-rows) with one 原则缺 (B1) and one mechanizable candidate (C1) inside; the cli seat's two later comments (5641485675, 5641577546) read as part of the card, corrections included. finding dropped; pm:queue · Task · priority:p3. Rows admitted for references/platform-readings.md, each in the card's CORRECTED wording: A1 (needs:contract-review blocks the merge — mergeable_state: blocked with mergeable: true, a label-less sibling clean); A2 (the clean → blocked → clean and blocked → unstable → clean sequences across a ready flip; unstable transient, not a failed check); A4 (a failure can be superseded by a later failure carrying a different diagnosis — latest-per-name collapse before any verdict); A5 as corrected — an exit code is a field literal and the reading is the printed verdict line (check-governed-merges exit 3 is GOVERNED on --test and PREREQUISITE NOT MET elsewhere); ⛔ :370 stays narrow, ⛔ no exit-table change here; A6 (check-half-states.mjs does full-repo I/O on --help — an early-read output file is empty, not clean; nohup … & inside a backgrounded tool call reports a false exit 0); A7 (an unquoted heredoc delimiter expands every backtick in the body — a request body never passes through an expanding shell context; cmd | tail; echo $? reads tail's status); A8 as corrected twice + comment item 1 — comments and issue bodies: the channel guarantees exactly ONE _Generated by … footer, idempotent on its own form, and a DIFFERENT spelling sent by the author yields two; POST /pulls (create) appends a session-URL block (+90 B) — one agent's measurement, marked as such; A9 (queue progress is read from event=merge_group runs; the queue branch name embeds the SPECULATIVE base; removed_from_merge_queue and merged arrive in no fixed order — never key on it); comment item 2 (HTML entities do not decode inside a code span; a bracketed placeholder inside a code span survives); comment item 6 (the wake relay escapes { } < in its rendering — judge the stored body from a GET, never the relay). A3: already recorded at :49 / :52, no edit. Not rows: B1 = #17569's subject (the control must share the claim's scope and failure mode) — a pointer comment on #17569 carries the formulation as evidence, ⛔ not landed twice; C1 (a helper making a bare fixed-string tree grep carry a wrap-sharing control) — a candidate noted for #17569's dev's zone 3, ⛔ not a deliverable; C2 — context; comment item 4 (the guard fired correctly) — noted; comment item 5 (a mid-task narrowing must name the replacement owner and the moment) — a 原则缺 with its own card #17729. fold-or-serial: FOLDED into the platform-readings.md family under #17680 (gates answered there); this member carries the largest share — candidates ≈ 13, the dev dedupes each against the table (already present / extends a row / new / refused) and reports the four counts.

Pointer: landed as part of the folded platform-readings.md family. Branch claude/issue-17680-platform-readings-rows, draft PR #17746 (base main, skip-changeset, a Fixes line for each of the five members, head fe5fb9d8). This card contributes twelve new rows plus two in-place corrections across A1, A2, A4, A5, A6, A7, A9 and comment items 2 and 6. A3 and the A8/A9 halves already on the tree land nothing and are reported as already-present. B1, C1, C2 and comment items 4 and 5 are outside this PR, as the grading directs. The full os-dev-report — the candidate table, the four dedupe counts (candidates 31 / landed 24 / already present 7 / refused 0), the line budget (425 to 448, ceiling moved by exactly the landed delta, every new line at or under 120 bytes) and every gate with its exit code — is the report comment on the chain head #17680. Governed surface: the PR stays draft at the human terminal; ⛔ no seat flips it ready, enqueues it, or arms auto-merge.
