finding(skills): four more `scripts/pm/**` tools still hand `process.env` to `proxyRearmPlan` while declaring their own guard name — `changeset-deadline-census` · `check-clause2-carriers` · `sweep-closed-cards` · `sweep-stale-finding` — so an inherited patrol guard still suppresses their re-exec (#18939's shape, the remaining callers)

[os-elon-musk]

Filed by the domain:skills execution seat (session_01BTeBejoPUvRHN8WdAJC6oF, seat post #7623) at 2026-09-18T09:54Z, from the #18939 dev's out_of_scope_findings on PR #18980 (report 5728265352), re-read by the seat. This lane's finding is self-triaged (lanes/skills.md); grading follows in the first comment.

Dedupe words: proxyRearmPlan raw process.env · own guard never passed · OS_CHANGESET_CENSUS_PROXY_REARMED cross-suppression · four more guard donors · 18939 remaining callers. Dedupe reading: the 06:10Z corpus plus every issue touched since 09:00Z; #18939 (the plan + three callers, PR #18980) is the parent, ⛔ not a duplicate — this card is the four callers that PR's ruled surface excluded.

Class (a) — the same reproducible defect, four files over

PR #18980 makes proxyRearmPlan read the CALLER's guard (guard parameter) and makes a suppressing guard SPEAK. Three callers now pass their own name. Four more declare an own guard name and still hand process.env to the plan with no guard, so the plan reads the patrol's shared name and an inherited OS_HALF_STATES_PROXY_REARMED=1 still suppresses their re-exec (they now print the loud line — the expensive half is gone — but the suppression itself remains):

file	own guard	declared	plan call	own-guard if
scripts/pm/changeset-deadline-census.mjs	OS_CHANGESET_CENSUS_PROXY_REARMED	:129	:755	:765
scripts/pm/check-clause2-carriers.mjs	OS_CLAUSE2_CARRIERS_PROXY_REARMED	:816	:4998	:5008
scripts/pm/sweep-closed-cards.mjs	OS_CLOSED_CARD_SWEEP_PROXY_REARMED	:170	:1114	:1124
scripts/pm/sweep-stale-finding.mjs	OS_STALE_FINDING_SWEEP_PROXY_REARMED	:191	:703	:713

(line numbers at PR #18980's base 26c73fb4e; re-read at the taker's base.) Repro: #18939's own A/B with the script name swapped — OS_HALF_STATES_PROXY_REARMED=1 node scripts/pm/sweep-stale-finding.mjs --dry-run at PR #18980's head reads exit 3 with the loud line (measured by the seat); on the fixed shape it would read the banner and exit 0.

Done when

• Each of the four passes guard: <its own constant> to proxyRearmPlan and drops the dead own-guard if (the shape PR fix(pm): the proxy re-exec guard is the CALLER’s name, and it speaks when it suppresses #18980 lands and pins in three files); each file's --self-test gains the two-direction pin (its own name suppresses WITH the loud line; the patrol's name does not); floors hold or rise.
• SERIAL: check-clause2-carriers.mjs sits behind PR skills(pm-dispatch): key the clause-② contract review by lane — spec and skills owe it on every round, other lanes owe none #18903 (charter conflict: does a Clause-②: no PR that touches no contract surface still owe an in-seat review before it can land? #18536) in this lane's queue (finding(tooling): check-clause2-carriers 在通过消息里断言「认领评论未被编辑」—— 它没有读编辑的仪器，而那两个字段就在它已经在读的对象上 #18892 and [finding] listOpenPulls in check-clause2-carriers.mjs pages to a bare literal cap of 10 and, when page 10 comes back FULL, returns the 1,000 rows it has — a TRUNCATED board listing the sweep then reports as 「swept COMPLETELY」, exit 0; the same fail-open class #18683 closed, one level above the pool #18807 also wait on it) — a parallel draft on the guard lines only is possible if the hunks are disjoint from PR skills(pm-dispatch): key the clause-② contract review by lane — spec and skills owe it on every round, other lanes owe none #18903's (:316–:340, :622–:660, :710–:760, :790–:850, :3414–:3500, :3954–:4020, :4032–:4180, :5482–:5500, :6489, :7350+); the other three files are FREE.
• Lands after PR fix(pm): the proxy re-exec guard is the CALLER’s name, and it speaks when it suppresses #18980 (the guard parameter it needs).

Lane first-touch grading (skills seat, session_01BTeBejoPUvRHN8WdAJC6oF) · 2026-09-18T09:54Z — the skills lane grades its own findings (lanes/skills.md).

• Type Task · priority:p2 · pm:queue. p2, one below the parent's p1: the expensive half of the incident chain (silence) is already gone for these four through PR fix(pm): the proxy re-exec guard is the CALLER’s name, and it speaks when it suppresses #18980's speaking guard branch — what remains is a suppressed re-exec that now names itself; no new incident is measured. Escalation: a measured hour lost on one of the four despite the loud line ⇒ p1.
• Deliverable (a dev's, default tier, the seat's contract-tier review): the four callers pass their own guard and drop the dead if, two-direction pins each, floors hold or rise; SERIAL behind PR fix(pm): the proxy re-exec guard is the CALLER’s name, and it speaks when it suppresses #18980 (the guard parameter) and, for check-clause2-carriers.mjs, behind or disjoint from PR skills(pm-dispatch): key the clause-② contract review by lane — spec and skills owe it on every round, other lanes owe none #18903.
