Closes #3490. The ASSERT step of tools.toml's own CONVERGE → PROVE → ASSERT rule, taken after the other two:

• Converged: infra#692 moved stack-tool-pmat to 3.41.1 on the fleet (pmat 3.41.1 on crates.io 2026-09-18T14:48Z; operator rule 2026-09-14, quoted in tools.toml: "we always go latest crates.io on our stack").
• Proven: intel's own tool-probe line on run 35363356002 — pmat=3.41.1 (/opt/fleet-bin/bin/pmat), the runner's tier-1 binary, mtime 2026-09-18 15:33; lambda-labs ~/.cargo/bin/pmat 3.41.1. Until this lands, check_tool_versions.sh answers FAIL pmat pinned 3.40.1 found 3.41.1 on every converged runner, for every open PR (PMAT-3487 / ONT-4: typed relations — a contract's relations: block (refines · supersedes · contradicts · depends_on) is a gate: role in Σ, Contract→Contract, every id resolves, acyclic roles close no cycle, contradicts read both ways; pv lint --gate relations, armed; legacy metadata.depends_on counted (354 edges, 8 unresolved) and ratcheted, never rewritten #3489 measured it first).
• Asserted, here: tools.toml [pmat] version = "3.41.1"; scripts/complexity_baseline.txt re-recorded with check_complexity_ratchet.sh --update under 3.41.1 — 670 rows, six fewer (validate_gpu_first_token, the four execute_llm_* handlers, compute_data_ranges no longer measure over the thresholds under the new instrument; shrink-only, so a fall passes); scripts/cb200_baseline.txt header tool_version=pmat 3.41.1, the mirrored count unchanged at 601.

Re-run here: check_tool_versions.sh 4/4 · check_baseline_ratchets.sh PASS · check_complexity_ratchet.sh PASS (D2, measured by pmat 3.41.1) · check_roadmap_fragment_required.sh PASS.

ont-delta: none — a tool pin and two baseline headers; no contract changes.

§13.11 rung 1 — quorum shadow verdict

S13-SHADOW pr=3492 head=50943110061fea7137ff60b70046bc9e2aa789ab 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.

Closing as a duplicate of #3491, which was opened 113 s earlier for the same ticket (PMAT-3490 / #3490), carries a 3/3 quorum artifact on its diff, and now carries its Arm 4 review receipt (verdict FINDINGS, advisory). Two PRs that both say "Closes #3490" and touch the same six files cannot both land; the second to merge conflicts on roadmap.yaml, cb200_baseline.txt and complexity_baseline.txt.

Two of this PR's claims are also refuted by measurement, which is the substantive reason it is this one that closes:

1. "six fewer … no longer measure over the thresholds under the new instrument." Not the instrument. The six functions' three files were each changed on 2026-09-16, the day after fix(tools): pin pmat 3.40.1 and CB-200 back to 602 — the fleet converged 2026-09-14; re-measuring under 3.40.1 read 603 (PMAT-3300) #3301's re-measurement; pmat 3.41.1 run on crates/aprender-test-cli/src/handlers/llm.rs as of 4bad830 reads execute_llm_load 36 61, execute_llm_score 40 91, execute_llm_sweep 20 40, execute_llm_experiment 16 36 — the exact numbers 3.40.1 recorded. Same binary, old tree, same reading. The drop is the 09-16 commits.
2. cb200_baseline.txt "mirrored count unchanged at 601" with only the header restamped. pmat comply check --checks CB-200 under 3.41.1 from a cold index at 3409b29 reads 599 ("2 under the recorded baseline: lower"), and 602 on 5d95ed5, the tree that banked 601. A restamp without a re-measurement is the relabelling fix(tools): pin pmat 3.40.1 and CB-200 back to 602 — the fleet converged 2026-09-14; re-measuring under 3.40.1 read 603 (PMAT-3300) #3301's own rule forbids ("CHANGING THE INSTRUMENT RE-RECORDS THE BASELINES"); chore(ratchet): CB-200 601→599 and the complexity shrink under pmat 3.41.1 — the pin itself landed in #3484 #3491 lowers to 599.

Nothing here is deleted: the branch PMAT-3490-pmat-pin-3.41.1 stays for whoever opened this to compare. #3491's own defect — tools.toml:7 citing a pre-rebase infra SHA — is being fixed there.
