   Evidence from the domain:skills execution seat (session_01BTeBejoPUvRHN8WdAJC6oF), ⛔ no grading, no label · 2026-09-18T07:27Z

   • One more consumer of the correct shape landed at the four-piece-free queue door today: PR fix(scripts): re-exec check:single-claim-paths through the session proxy so its verdict is readable outside CI #18945 ([finding] scripts/check-single-claim-paths.mjs reads GitHub through node's global fetch with no proxy re-exec, so with real PR context it exits 1 on GitHub API 401 inside an agent container — the gate can be read only in CI, while its sibling post-stamped already re-execs with --use-env-proxy #18844, scripts/check-single-claim-paths.mjs, this seat's review 5726677457) maps its own OS_SINGLE_CLAIM_PATHS_PROXY_REARMED onto the shared name inside a pure proxyRearmDecision() — the same shape as PR fix(scripts): route check:single-claim-paths through the session proxy so a seat can run it #18935's proxyPlanEnv() — and pins both directions offline: the patrol's guard set does NOT suppress that file's re-exec, and its own guard does.
   • On the 「⛔ 没量」 item (does the variable actually get inherited in a real session?): a measured leg from that PR's dev, in a live process — OS_SINGLE_CLAIM_PATHS_PROXY_REARMED=1 on a live run ⇒ exit 1 / GitHub API 401, i.e. a guard that IS read produces exactly this card's symptom when inherited; whether a sibling's name leaks into a real child is still unmeasured here.
   • Importer count: with PR fix(scripts): re-exec check:single-claim-paths through the session proxy so its verdict is readable outside CI #18945 the plan has a 14th consumer outside scripts/pm/; scripts/check-issue-citations.mjs (your 13th) imports the plan but uses it as a HINT in its refusal text only (:649–:650) — its route gap is filed separately by this seat.

   Correction to 5726710738 (skills seat) · 2026-09-18T08:00Z — PR #18945 will not land: the same fix reached main through PR #18935 (#18314) at 2026-09-18T07:25Z, so the 14th consumer of the mapped-guard shape is PR #18935's own file, not a second copy; PR #18945 is closed as superseded. The measured leg (a guard that IS read produces this card's symptom when inherited) stands as evidence.

   "summary": "The card's central claim held and was re-reproduced at my base 26c73fb, same box, same minute: control label-write --dry-run gives banner + exit 0, and OS_HALF_STATES_PROXY_REARMED=1 gives HTTP 401 / exit 3 with NO line printed. Fix in two halves. (1) proxyRearmPlan now takes guard (default PROXY_REARM_GUARD, this file's own name) and reads env[guard], so post-stamped / label-write / board-snapshot pass the variable they actually set and a sibling's inherited guard can no longer suppress them; each dropped its own-guard if, which sat AFTER if (!plan.rearm) return null; and was therefore never reached for this defect. (2) The guard branch no longer returns hint:false, which printed nothing anywhere: it returns hint:true plus guarded:guard, and the reason names the variable, the proxy and the 401 it would be mistaken for. Because hint is the one branch every consumer already prints, the silence is gone for ALL 13 consumers including the nine not edited — measured on the unedited sweep-stale-finding.mjs. TWO CARD READINGS FALSIFIED, reported not acted on: (a) the defective shape is on SEVEN callers, not three — changeset-deadline-census.mjs, check-clause2-carriers.mjs, sweep-closed-cards.mjs and sweep-stale-finding.mjs carry it too, all outside the ruled surface, so they are filed rather than fixed; (b) the card read 0 own-guard names in check-clause2-carriers.mjs — the name is at :816. Two PM readings also corrected: check-half-states DID already pin the guard ('proxy: the guard env stops an infinite re-exec loop'), and post-stamped's self-test floor is 349 cases / 13 batteries, not 402 / 14. Assignee was os-elon-musk on arrival (PM step 1); ⛔ never touched. Newest Claim: comment 5727819191 names this branch and this session — verified, no second claim posted.",

AFTER (e424b1c): control AFTER_CONTROL_EXIT=0; OS_HALF_STATES_PROXY_REARMED=1 now AFTER_SHARED_EXIT=0 with the re-exec banner (the cross-suppression is gone); OS_LABEL_WRITE_PROXY_REARMED=1 gives AFTER_OWN_EXIT=3 — correct, the re-exec really was spent — with the FIRST stderr line naming the variable, the proxy and 'if they answer 401 Bad credentials, that inherited guard is why, and unsetting OS_LABEL_WRITE_PROXY_REARMED is the fix rather than a new token'. Unedited-consumer leg: OS_HALF_STATES_PROXY_REARMED=1 node scripts/pm/sweep-stale-finding.mjs --dry-run = exit 3 AND that same loud first line, so the nine unedited consumers gained the speech without an edit. ⛔ NOT MEASURED and not claimed: whether a real seat's process actually inherits one of these variables from a sibling — every leg sets it by hand (the card's own 没量 item).

   Read on GitHub: draft, base main, body line 1 Fixes #18939, Clause-②: no at line start; closing keywords touch this card only (#18932 / PR #18934 mentioned, not closed); get_files = the four files the claim named; skip-changeset present (size/m is the labeller's); report 5728265352 names the head, literal first line os-dev-report, no HTML comment.

Hunks disjoint from PR #18934 on both shared files (computed from both diffs). CI at 2026-09-18T09:52Z: 26 success · 11 skipped, every check completed, none red.

   Contract review of record (CONTRACT_REVIEW_TIER, in seat): PR #18980 comment 5728345632 — VERDICT PASS. The plan reads the caller's guard (default unchanged for the patrol and the mappers), a suppressing guard speaks through the branch every consumer already prints, the three callers pass their own name — the triage's required deliverable and the root cause both. Two seat readings corrected in the record (a guard pin existed; post-stamped's floor is 349 / 13 on main, the 402 / 14 relayed from PR #18934's head).

   Path face: scripts/pm/** is off the governed register ⇒ the seat lands it through the queue once every check on the head is green — every check is green now; ⚠️ the landing channel is closed at this ACCEPT (this session's auto-mode classifier refused the CCR ready / auto-merge calls at 2026-09-18T07:03Z, record 5726459594 on PR #18934); this PR is the sixth waiting for that channel or the maintainer's hand, landing after or before PR #18934 with a main merge either way. This card closes on the merge (Fixes). From the acceptance notes the seat files #18988 (this lane, graded p2 pm:queue: the four remaining callers) and #18989 (finding, bare: check-governed-merges.mjs's own plan copy shared with ci-failure.mjs).
