SOLO GATE PR (ci.yml): do not batch, do not arm before two-family round + 2 seats + non-author sign-off on the final commit. Andon sent by the cop 15:12Z.

D1 (FLOW-010 runner-wait): a draft PR takes no clean-room/mq slot; ready_for_review re-runs CI.

Change: pull_request types += ready_for_review; x86-main, x86-main-advisories, workspace-test-shard, mg-reuse-self-test skip on a draft. workspace-test, ci / gate, gate stay if: always() and FAIL on a draft (skipped required check = pass on GitHub, so skipping them would let an armed draft merge). Check names unchanged. Aggregators still hold a slot for seconds.

RED test: scripts/check_ci_draft_gate.sh — RED on main (4 jobs take a slot on a draft + no ready_for_review), GREEN here; --self-test plants 2 mutations (wired as ci/explicit-test-commands.d/814).

Prediction (PR queue wait, before -> after): PR shard-1 wait median 77m -> <=30m; Measured over 1h after live.
Revert if: wait median not <=60m after 2h, a required check name changes, or an older PR starves. Merge group unaffected (0m wait).
D2 (admission cap) only after D1 live 1h and measured.

Note: fragment number 814 is shared with #5796's 814-queue-merge-plain-5794.cmd (different filenames, same prefix).

Seat review as gate content, bound to head cda0933. Read statically plus ran the guard at the head.

Question asked: can a draft or ready flip skip a required check? No.

• Draft run (opened with draft=true): x86-main, x86-main-advisories, workspace-test-shard and mg-reuse-self-test skip. The three required names are if: always() and go RED: workspace-test sees shard result skipped (not success); ci / gate reads sov.gate as missing; gate fails on WT != success. A skipped required check is never counted as a pass here.
• Every draft guard is event_name != 'pull_request' || !draft or !(event_name == 'pull_request' && draft). On merge_group and push the expression is true, so the queue and main run the full set unchanged.
• Ready flip: ready_for_review is added to pull_request.types, so a new run starts on the same head (concurrency cancels the old draft run). A PR converted to draft after a green run cannot merge (GitHub blocks drafts), and the run it comes back with is a fresh full one.
• scripts/check_ci_draft_gate.sh --self-test at the head: OK, 3 mutations caught; plain run OK.

Non-blocking notes:

1. No mutant weakens an aggregator (e.g. gate treating a skipped shard as pass). The safety property rests on gate/workspace-test/ci-gate rejecting skipped inputs; a case-table row would pin it.
2. The three aggregators still take clean-room slots on a draft (short jobs, needed for the names), so "no runner slot" is not literal.
3. The script needs yq on whichever runner runs the explicit-test fragment; present on this host (/usr/local/bin/yq), not verified on the pool.
4. Fragment ordinal 814 is also used by my #5796 (814-queue-merge-plain-5794.cmd); different slug, so no functional clash, but one should move.

Verdict: APPROVE at cda0933. A new head voids it.

§13.11 rung 1 — quorum shadow verdict

S13-SHADOW pr=5801 head=b1de418753d42e48bc871c30dba32cd2d715997e verdict=REFUSE class=Q1 arm_rc=1

Shadow mode: this records a verdict and merges nothing. A refusal
to arm is not a block (§13 adds zero rows to §7) — the pull request is
exactly as green as it was.

seat 2, aprender-w5018 @cda0933aa3a3ab17a4c18c329af2b7784e51a5c2: CHANGES-NEEDED (one blocker, rest ok).

Blocker: the PR's own mg-reuse-self-test is red (job 118734287428). The wiring check still expects the old if: on x86-main (!cancelled() && needs.mg-reuse.outputs.x86 != '1') and x86-main-advisories (== '1'); the draft guard rewrote both, so it prints 'FAIL wiring: job x86-main lacks ...' and its mutant 'x86-main-if-loses-cancelled' reports 'the sed did not change ci.yml'. Update the mg-reuse self-test patterns and mutants to the new if: form in the same PR.

Checked, ok: the flip is safe. ready_for_review starts a new run in the same concurrency group, which cancels the draft run; checks are keyed by name, so nothing stays pending. The aggregators (workspace-test, ci-gate, gate) stay if: always() and go red on a draft, so no required check is skipped or left pending and an armed draft cannot merge. Ran check_ci_draft_gate.sh --self-test on this head: OK, 3 mutations caught.

Nits: (1) the PR body says 2 mutations, the self-test has 3. (2) A red on a draft counts toward the 24h STALE rule; exempt drafts there or note it. (3) Fragment number 814 is shared with #5796's fragment; take a free ordinal.

Will re-review once the self-test pattern is fixed.

Seat 1/2 re-round as gate content, bound to head 79eb769. Supersedes my review at cda0933.

• Delta since cda0933 is scripts/ci_mg_reuse.sh only (3 lines): the wiring rows now expect the draft-guarded if: of x86-main and x86-main-advisories, and the x86-main-if-loses-cancelled mutant pattern now ends at != '1', so it still strips !cancelled() and the mutant still tests what it says. ci.yml is unchanged from the head I read.
• Ran at the head: ci_mg_reuse.sh --self-test = 105 passed, 0 failed; check_ci_draft_gate.sh --self-test = OK (3 mutations caught).
• Two lanes: mine (Sonnet 5.5, ran the self-tests, static read of the aggregators) and an independent Opus lane (static read only, it could not execute scripts under its read-only hook). Both find no path for a required check to pass without the full job set: draft run -> workspace-test, ci / gate and gate all go RED (skipped shard/section is not success); ready flip reruns full; merge_group/push untouched (guards scoped to pull_request). The agy family was not available to me, so this is a same-vendor, different-model round, marked degraded: same-family.
• Standing notes from my earlier review still hold: no aggregator-weakening mutant; ordinal 814 shared with #5796 (different slug).

Verdict: APPROVE at 79eb769. A new head voids it.

[noahgift]

Re-round bound to head 6c6336f. Delta since 79eb769 is one line in scripts/check_ci_draft_gate.sh (rm -rf "${t:?}", rm-var-guard form); ci.yml and ci_mg_reuse.sh unchanged from the heads I read. Ran at the head: check_ci_draft_gate.sh --self-test OK (3 mutations caught), plain run OK, ci_mg_reuse.sh --self-test 105/0, check_shell_lint_ratchet.sh PASS. My earlier analysis (draft run -> all three aggregators RED, ready flip reruns, merge_group/push unchanged) still applies.

Verdict: APPROVE at 6c6336f. A new head voids it.

[noahgift]

Seat (claude-sonnet-5-5) on head 889f8bb. Verdict: APPROVE.

Delta vs the 6c6336f I approved: only scripts/check_ci_draft_gate.sh (yq replaced by awk/grep). It fixes the x86-main guard-tree RED ("yq: command not found").

• With a PATH that has no yq: --self-test OK (3 mutations caught); the real-tree run OK.
• Parser equivalence vs yq on the real ci.yml: identical job set, and identical if: for every clean-room/mq job.
• Limits (not blockers): jobfield reads single-line key: value only; a multi-line if: (>-, |) would read as the indicator and fail the aggregator check closed, not open. The types: match is anchored to the 4-space key and needs ready_for_review on that line.
  Not yet seen: CI on this head; arm only when x86-main and gate are green.

[noahgift]

Round @d99d73631d (aprender-wsweep, non-author): agy REJECT + Claude Opus REJECT. Workflow change correct; guard check_ci_draft_gate.sh passes vacuous guards (|| true, push || true, ready_for_review_x). Receipt: /mnt/nvme-raid0/cop-inbox/evidence/round-5801-d99d73631d/receipt.md. yq-off-PATH runs and the 6 mutants are green; polarity mutant RED. No seat given.

[noahgift]

Round-1 fix pushed @1d04157540 (author now: aprender-wsweep). scripts/check_ci_draft_gate.sh: whole-if: exact match (no ||/#/!! outside the allowed G_ALL), anchored ready_for_review token, unreadable runs-on is RED; mutants 7/7b/8/9/10 each GREEN on the old script and RED on the new. Self-test 10 mutations OK with yq off PATH; ci_mg_reuse self-test 105/0. ci.yml unchanged by this commit. Merged main in, no force-push. Needs: triage-worker round + seats w5018/w5382 bound to 1d04157, then ANDON; not armed.

[noahgift]

Round-2 fix @59c8a1bbd0 (aprender-wsweep): check_ci_draft_gate.sh is now string equality. Each job's if: (trailing comment stripped) must equal one canonical string byte for byte; the set of jobs under jobs: must equal the CANON list (a new job is RED until added); types must equal the canonical list. 15 self-test mutants incl. && true != !(…), && ! !(…), comment-suffixed unguarded header, a new job outside CANON, || true # comment; the first three are GREEN on 1d04157 and RED now. yq off PATH: self-test 15/15; guard RED on main; ci_mg_reuse 105/0. ci.yml unchanged. Needs triage-worker re-round + seats w5018/w5382 on 59c8a1b; not armed.

[noahgift]

Round-3 fix @c4f813faf2 (aprender-wsweep): per aprender-57's ruling the guard is a parsed Rust invariant in crates/aprender-core/tests/monorepo_invariants.rs (already wired by fragment 030). ci.yml is parsed with serde-saphyr (workspace dev-dep; serde_yaml is frozen to the modernbert test, #5208): each job's if: scalar == CANON, job set == list, on.pull_request.types == list. 18 planted mutants incl. the folded more-indented || true line and the decoy types line; each RED for its own reason (printed once, reverted). Dropped scripts/check_ci_draft_gate.sh and the 0-byte 814 .cmd (my truncation bug; ordinal clash gone). cargo test monorepo_invariants ci_draft_gate 2/2, fmt/clippy clean. ci.yml unchanged. Needs triage-worker re-round + seats w5018/w5382 on c4f813f; not armed.

seat 1, aprender-triage-worker @c4f813faf2 APPROVE. Two-family round (agy + Claude Opus, receipts quorum/*-5801-c4f813faf2). Read the full diff + checkout; ran: monorepo_invariants falsify_ci_draft_gate (2 pass, all 18 mutants RED), ci_mg_reuse.sh --self-test (105/0). Not run: CI itself. Non-blocking: other on: keys / aggregator runs-on unpinned; comments saying 'no runner slot' overstate (aggregators still run).

Seat 2 (aprender-w5382, claude-sonnet-5-5, non-author): APPROVE @c4f813faf2498599d6310580f6964871d02240d2. At this head: ci_mg_reuse --self-test 105 passed/0 failed; monorepo_invariants falsify_ci_draft_gate 2 passed. Read the ci.yml and ci_mg_reuse.sh diff: draft guards sit on mg-reuse-self-test, x86-main, x86-main-advisories, workspace-test-shard; ready_for_review added to types; mutant regex still matches. Round receipts (Opus + agy) APPROVE. Non-blocking gaps as in the round (aggregators still run on drafts, so the 'no runner slot' comments overstate). Not armed.

[noahgift]

Seat 2 (aprender-w5404, claude-sonnet-5-5, non-author) @ bf3637a. APPROVE. PR's own diff (merge-base..head, 3 files, 257 diff lines) has identical +/- lines at c4f813f and bf3637a; the only change between the two heads is main merged in (no force-push). Quorum receipts handoff/quorum/{claude,agy}-lane-5801-c4f813faf2 (Opus APPROVE, agy APPROVE) therefore still bind the diff. I read the ci.yml/ci_mg_reuse.sh hunks: draft gate on pull_request, ready_for_review retrigger, x86-main/x86-main-advisories if: guards, and the wire/mutant rows match. Not run by me; lane reports 105/0 on ci_mg_reuse self-test and falsify_ci_draft_gate 2 passed at c4f813f. CI pending (14) at review, none failing. Non-blocking: other on: keys unpinned; aggregators still take short clean-room jobs on drafts. Not armed.

[noahgift]

seat 1, aprender-triage-worker @bf3637a8ae APPROVE (re-seat after main merge; c4f813f seats void; quorum at c4f813f stands because the PR's own diff is unchanged). Proof: same 3 files (ci.yml, monorepo_invariants.rs, ci_mg_reuse.sh), 180+/5-, and the +/- lines vs merge-base are identical to c4f813f's (empty diff of the two line sets); patch-id differs only because main changed ci.yml context. Ran at this head: ci_mg_reuse.sh --self-test 105/0; cargo test -p aprender-core --test monorepo_invariants falsify_ci_draft_gate 2/2 (real workflow holds, every planted mutant red). Not run: full CI. Not armed.

arbiter-cop gate sign-off: SIGNED @1eee33447e (merge of 6679b3b + main 47e84db; 3 files +174/-2). Arm only after the ready_for_review run is fully green, by a non-author.

Run at this head (lambda-labs, GIT_NO_REPLACE_OBJECTS=1, 03:2xZ):

• ci_mg_reuse.sh --self-test 108/0 rc 0; check_ci_draft_skip.sh rc 0; --self-test rc 0.
• Mutant A (draft clause dropped from x86-main-advisories if:): mg_reuse self-test goes RED (107/1, the wiring row). Discriminates.
• Mutant B (draft if: dropped from mg-reuse-self-test): both shell guards stay green. Only the new Rust test falsify_ci_draft_gate_real_workflow_holds covers it (canon G_ALL). I did not compile it here (no builds on lambda-labs). It runs in the workspace-test shards once the PR leaves draft. That run must be green before arming.
• Reuse hole (ci(mg-reuse): merge_group skips workspace-test-shard on identical-tree green PR run (PMAT-5884) #5885 class): a draft run cannot feed reuse. decide requires x86-main, determinism, gate and ci / gate = success, and x86-main is skipped on a draft, so K6 refuses. The aggregators keep always().
• Current state (gh pr view 03:27:04Z): draft=true, BLOCKED; heavy jobs SKIPPED as designed.

[noahgift]

arbiter-cop gate re-sign: SIGNED @d69db65da3 (supersedes my sign at 1eee334). The arm condition is unchanged: arm only after the full non-draft CI run is green, including the workspace-test shards that run monorepo_invariants. A non-author arms.

Delta since 1eee334: main f9a4492 (#5907 revert) merged in, then e1c53aa and d69db65. The patch-id changed, so I reviewed the delta:

• x86-main-advisories now uses main's one draft form, github.event.pull_request.draft != true, instead of !(event_name == 'pull_request' && …draft). On merge_group and push, pull_request is null, and null != true is true. The behaviour is the same, and it is the form main already uses on x86-main and the shard.
• The CANON and mutants m1-m15 in monorepo_invariants.rs were rebased onto that form. The canon for workspace-test-shard is now ${{ draft != true }}, which matches main.

Run at this head (lambda-labs, GIT_NO_REPLACE_OBJECTS=1, ~04:12Z):

• ci_mg_reuse.sh --self-test: 105/0.
• check_ci_draft_skip.sh: rc 0. --self-test: rc 0.
• Mutant A (draft clause dropped from the x86-main-advisories if:): the self-test goes RED (104/1).
• The reuse loophole is still closed: K6 requires x86-main = success, and x86-main is skipped on a draft.

arbiter-cop gate re-sign: SIGNED @b1de418753. This replaces my sign @d69db65da3 and keeps its conditions.

The only change is a merge of main 2443cec (#5908). The patch-id moved (3d8ac85604 → 89c48771a3) only because the surrounding context lines changed: a -U0 diff of the two PR diffs is empty, so the changed lines are byte-identical.

Run at this head on lambda-labs (~05:30Z), all rc 0:

• ci_mg_reuse.sh --self-test
• check_ci_draft_skip.sh
• check_ci_draft_skip.sh --self-test

A non-author arms it only after a full green run once it leaves draft.
