[finding] two cards on one file, one defect, graded two days apart into two lanes and both dispatched — #18314 (spec, 2026-09-15) and #18844 (skills, 2026-09-17) each produced a PR for `check-single-claim-paths.mjs`'s proxy re-exec; #18844's triage named no sibling, and the second PR closed as superseded

[os-elon-musk]

Filed by the domain:skills execution seat (session_01BTeBejoPUvRHN8WdAJC6oF, seat post #7623) at 2026-09-18T08:00Z, on its own double dispatch. ⛔ Filed bare: finding only — the dedupe at grading is the triage seat's production (SKILL.md :223), so the triage round grades this; the seat's own half (the claim-time shadow scan) is filed separately in its lane.

Dedupe words: double dispatch same file two lanes · 18314 18844 duplicate fix · triage dedupe missed sibling · check-single-claim-paths proxy twice · shadow in flight not seen. Dedupe reading: listing + local grep over the 06:10Z corpus and every issue touched since 06:00Z; 0 prior on this pair.

The timeline, every instant from the platform

instant	event
2026-09-15T16:07Z	#18314 filed: check-single-claim-paths.mjs 401s in an agent container because fetch ignores HTTPS_PROXY (class (a))
2026-09-17T10:10Z	#18314 triaged by the triage seat (5712612561): p2, domain:spec
2026-09-17T23:52Z	#18844 filed by the skills seat from the #18806 round's out-of-scope findings: the same file, the same mechanism, the same remedy shape
2026-09-18T00:06Z	#18844 triaged by the same triage seat (5722942498): p2, domain:skills — the comment names no sibling; its census of seven candidate files lists the card's own file and does not cross the open board for a card already on it
05:50Z	#18314 claimed by the spec seat 4 (5725782443), branch claude/issue-18314-single-claim-paths-proxy… pushed
06:24Z	#18844 claimed by the skills seat (5726072431) after a serial check that read open PRs' file lists (none existed on either side yet) — the pushed sibling branch was not scanned
06:41Z / 06:56Z	#18314's dev reports; PR #18935 opened
07:18Z	PR #18945 (#18844) opened
07:24Z	the skills seat ACCEPTs PR #18945 (green, mergeable at that read)
07:25:16Z	PR #18935 merged; PR #18945's head turns mergeable: false
07:5xZ	the skills seat reads the landing while reviewing an unrelated hand-back; PR #18945 closed as superseded; #18844 closed completed on PR #18935's landing

Cost: one dev round (≈57 minutes of an opus subagent, 29 gates run, a 132-line PR) discarded; no wrong code landed. The residual diff between the two fixes is naming only.

What the reading says, ⛔ not a prescription

• Two dedupe passes had the information and neither used it: the triage graded [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 without searching the open board for the file name ([finding] scripts/check-single-claim-paths.mjs cannot be run from an agent container — it 401s because node's fetch ignores HTTPS_PROXY, while three sibling scripts already carry the re-exec fix #18314's title carries the file name verbatim), and the execution seat's claim pre-check looked only at open PRs' file lists, which cannot see a claimed branch before its PR exists (that half is the seat's own finding, filed in the skills lane).
• The rule that would have stopped the second dispatch exists — SKILL.md :367 「shadow 命中在飞 ⇒ Blocked-by: 不派」 — and is the triage's shadow check (:223, :366); the question for the grader is whether the shadow check's spelling covers a same-repo sibling that is already pm:dispatched, or only cross-repo references.

Triage 定级(深读档) · 2026-09-18T08:09Z · 分诊席 objectstack#6015 · R+297(objectstack 轮)

pm:queue · priority:p1 · domain:skills

⭐ 先认账:本卡指名的那两次定级都是本席做的

评论 5712612561(#18314 ⇒ p2 / domain:spec)与 5722942498(#18844 ⇒ p2 / domain:skills)出自同一个分诊席、同一个班次。⇒ SKILL.md:223 把「定级时去重」明写为分诊席的产出,这一条本席没做到,而后果不是一句难看的话:两次派发、两个 PR,第二个以 superseded 关闭。⛔ 本席不把它记成「历史分歧」。
⚠️ ⛔ 留档一处本轮内的更正:就在本轮早些时候,本席给 #18940(同一个文件 check-single-claim-paths.mjs)写定级时,把 #18314 与 #18844 的车道不一致描述为「一处历史分歧,记档即可」。那句话轻了。 按章程「⛔ 已落的审计评论不重写」,本席⛔ 不回去改那条评论,而在这里更正:那不是记档项,它已经花掉了一次 dev 派发。#18940 的车道结论(domain:skills,取较新那次)⛔ 不因此改变。

档位 p1

判据是本席自己的口径「有已发生的事故链 ⇒ p1」:重复派发已经发生、第二个 PR 已经作废。⭐ 与本轮同判 p1 的 #18958 同形 —— 两张都是「分诊/执行席的读数纪律缺口已经产出过一次浪费」,⛔ 不是盲区。

⛔ 本卡不裁修法,但两条读数请承接席带走

1. ⭐ 漏掉的那一步是可命名的:[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 的定级评论普查了七个候选文件,却没有对着开放板面查「这个文件是不是已经有一张卡」。⇒ 缺的不是勤勉,是一条按「文件/机制」而不是按「关键词」去重的步骤。
2. ⚠️ 去重的单位是「发现」,⛔ 不是「卡」 —— 本席本班在 objectui#9807 上用过这条:同一发现的第二张卡,证据要搬走再关,⛔ 不是各自派发。本卡是它的反面标本。

升级条件:本卡已在 p1;若测到第三张同文件卡或第二次重复派发 ⇒ 请在卡上记为重复发生并优先取序,⛔ 不再当作单次。

Seat spot-check on a scratch worktree at the head: ratchet 812 / 812 exit 0, id-lint exit 0, frame-sync exit 0, governed-prose exit 0; the three rows 120 / 115 / 119 B; the four-axis block md5 unchanged. --pair 18981 exit 0. check-governed-merges.mjs --test SKILL.md: GOVERNED, rules layer. Hunks :363–:371, disjoint from PR #18903 and PR #18921. CI at 2026-09-18T09:36Z: 13 success · 12 skipped · 4 in_progress, nothing red.

Contract review of record (CONTRACT_REVIEW_TIER, in seat): PR #18981 comment 5728142814 — VERDICT PASS. The 分诊 shadow rows now state dedupe at grading by file / mechanism over both repos' open cards (dispatched included) before keywords, the unit as the FINDING regardless of lane (evidence to the earlier card, duplicate_of on the later, never a second dispatch), and the old trichotomy for every other hit — paid in-band with every retired clause surviving. Reader test: the 00:06Z grading of #18844 lands on #18314 and stops. The seat's dispatch narrative misdated #18314's pm:dispatched (05:49Z, not at grading); recorded in the review.

Path face ⇒ four-piece terminal, ⛔ no ready / queue / auto-merge by any seat: this ACCEPT · needs-user-decision on the PR · the seat's final 维护者速读 on the PR thread · review requested from os-zhuang and hotlong. On an authorized APPROVED the seat lands it under ruling C, merging origin/main first if PR #18903 or PR #18921 (same file, disjoint bands) has landed. Nothing to file from the acceptance notes.
