Filing gate ①: a follow-up owed by in-flight work. Card #27637 (one mailbox per seat) states 「the migration of the three per-login mailboxes is a card-thread follow-up after landing」 (triage 6501344388); this is that carrier, with the contract review's should-fixes 2 and 3 on PR #27881 (record 6513700361). Filed by domain:skills seat 2 (#19287). ⛔ Not a claim. Grade and lane are triage's.

Business reason: once PR #27881 lands, the three open per-login mailboxes (#27523 marchtian, #27357 os-sales, #27309 os-justin) no longer match the seat shape. Their To: LOGIN comments and key-first comments read as refused, so no seat is woken through them until each seat opens its own.

Wanted (after PR #27881 is on `main`)

Each holding account closes its per-login mailbox with node scripts/pm/mailbox-open.mjs --close N and opens one mailbox per seat it holds with --seat. The seated session subscribes.
os-justin in this order: close pm:mailbox — os-justin #27309, then delete the legacy ref refs/heads/mailbox/os-justin, then open per seat. While that ref exists, a push of mailbox/os-justin/SLUG is refused as a directory/file ref conflict (measured by the pm:mailbox: one mailbox per seat, not per account — today a second lane seat under the same account is never woken #27637 card thread on a local bare repo).
The legacy comments on pm:mailbox — marchtian #27523 / pm:mailbox — os-sales #27357 / pm:mailbox — os-justin #27309 are not re-read under the new reader: they read as half-states (refused). The migration note says so, and any still-live fact in them is re-sent once to the new seat mailbox.
Seats with no mailbox today (for example the os-elon-musk seats domain:server#3, domain:server#4, domain:skills#2) open one at their next seating act.

Read fresh. The migration is as written: each holding account closes its per-login mailbox and opens one mailbox per seat it holds, in the stated order for os-justin's legacy ref. The seated session subscribes.

Responsibility: n/a — not a defect card (the follow-up #27637 owed)
Thread-read: 6514419117
Premise: partly moved, measured now. #27523 (marchtian) is already closed: closed by the relay 2026-11-01T18:34:11Z, and marchtian's seats hold per-seat mailboxes #28536 (domain:devx#2) and #28676 (domain:skills#2). #27357 and #27309 are still open. No open pm:seat post names os-sales or os-justin, so neither account holds a seat that would open a successor mailbox. The legacy ref mailbox/os-justin still exists.
Live facts in the legacy comments: #27309's last two (To: domain:devx#2, 2026-10-31) name #28338–#28342; all five are closed, so nothing is re-sent. #27357's last three are seat-online signatures of os-sales seats that no post now carries.
Serial constraints cleared: none touch these PRs or the ref.

Migration note · 2026-11-01T19:22Z

Closed: per-login mailboxes pm:mailbox — os-sales #27357 (os-sales, closing comment 6562678772) and pm:mailbox — os-justin #27309 (os-justin, closing comment 6562686706), both through mailbox-open.mjs --close. pm:mailbox — marchtian #27523 (marchtian) was already closed by the relay 2026-11-01T18:34:11Z. No per-login mailbox is open on objectstack now.
Successors: none is owed for os-sales or os-justin, because no open pm:seat post names either. marchtian's seats already hold per-seat mailboxes: pm:mailbox — domain:devx#2 · marchtian #28536 for domain:devx#2 and pm:mailbox — domain:skills#2 · marchtian #28676 for domain:skills#2.
Legacy comments: comments on pm:mailbox — marchtian #27523, pm:mailbox — os-sales #27357 and pm:mailbox — os-justin #27309 are not re-read under the per-seat reader; they read as refused. Only two carried a live fact: pm:mailbox — os-justin #27309's two 2026-10-31 notes to domain:devx#2, which name docs(qa): wave-3 checklist accuracy slice S4 — platform-core.json (#27377) #28338–docs(qa): wave-3 checklist accuracy slice S8 — RUNNER.md (#27377) #28342. All five cards are closed, so nothing is re-sent.
Seats with no mailbox yet: the roster (fleet-roster.mjs --repos objectstack-ai/objectstack --json, read now) lists seated rows with an empty mailbox column. They are repo:cloud#1 ([PM seat] repo:cloud#1 — 🟢 baozhoutao · session_01FSg7JRUiTPo8GrgT38tAWP #6026), repo:cloud#2 ([PM seat] repo:cloud · seat 2 — 🟢 os-zhuang #24145), repo:docs.objectos.ai#1 ([PM seat] repo:docs.objectos.ai — 🟢 zhuangjianguo · 由 zhuangjianguo 账户的项目负责 #9831), domain:spec#3 ([PM seat] domain:spec · seat 3 — 🟢 os-support-ai · 由 os-support-ai 账户的项目负责 #18883), domain:spec#5 ([PM seat] domain:spec · seat 5 — ⏳ vacant · 留守 #29571 #29618 (os-warren) #19357) and repo:www.objectos.ai#1 ([PM seat] repo:www.objectos.ai — 🟢 held · hotlong · session_01FeA1nwBz1ohH65dvffUGKr · R1 opened 2026-10-05 · positioning wave (copy PR + 5 posts on slots 10-08…10-22) · slot Routine trig_017aGwYCcm4ToQxSuQxU1gSi #12224). Each opens its own mailbox at its next seating act, as the card says. No other seat opens one for them. The roster flags no mailbox as being on no seat row.
Open: the legacy ref refs/heads/mailbox/os-justin (sha e4bd21fad693be781d49086bc6892b5c7a767faa) still exists. This seat's container may not delete a ref, so the deletion waits on the maintainer: either approval for this seat to delete it, or deletion by hand in the repo's branch list. Until then, a push of mailbox/os-justin/<slug> is refused as a ref conflict. Only a future os-justin seat opening a mailbox without --head would hit that. The card stays open for this one step.

Release: skills seat 2 signs off on the maintainer's order in the project thread (「skills 车道当前任务处理完就下班」). The claim 6562672235 is released and the assignee cleared. The card's one open step waits on a maintainer answer, so it goes to the decision box (needs-user-decision) rather than back to the queue.
Resume-from: migration note 6562702845. #27357 and #27309 are closed (#27523 was already closed). What remains is the legacy ref refs/heads/mailbox/os-justin (sha e4bd21fad693be781d49086bc6892b5c7a767faa): the seat's git push origin :refs/heads/mailbox/os-justin was refused by the session's destructive-git guard, and the maintainer was asked in the project thread to answer 「删」 (or delete it in the GitHub UI) or 「留着」. On 「删」 or a UI delete, verify with git ls-remote origin refs/heads/mailbox/os-justin (empty) and close the card completed; on 「留着」, record that on the card and close it completed. No branch, no PR.

Brief-claimed-by: session_01QsR2jV5sBSzCYNEDgpYLJw · batch #452 · 2026-11-02T03:50Z

Director seat (第 56 场). Presented to the maintainer in batch #452, item 3. The migration note 6562702845 and the release 6567285842 are the reading: the three per-login mailboxes are closed, no live fact needs re-sending, and one step remains, the legacy ref refs/heads/mailbox/os-justin (sha e4bd21fad693be781d49086bc6892b5c7a767faa, recorded for restore), which the seat's container may not delete. This seat's increment:

Facets: ① the ref is dead and only blocks a future os-justin mailbox push (ref/directory conflict); deleting it is subtraction. ② no one hits it today; os-justin holds no seat. ③ once gone, no future seat spends an hour on an opaque ref conflict. ④ nothing is added either way.
Options: 删 (the maintainer deletes it in the branch list, or authorises the skills seat to run git push origin :refs/heads/mailbox/os-justin), 留着 (record and close).
Recommendation: 删. Workload: one click or one authorised command; then git ls-remote origin refs/heads/mailbox/os-justin empty and the card closes completed.

os-decision-facets
① 长远：死引用只会在将来绊人，删是减法
② 拉动：今天没人撞；os-justin 不坐席
③ 防 AI 犯错：删掉后不会有席位对着引用冲突猜半天
④ 不扩散：两种选择都不加东西

Closed — the last step is done · 2026-11-02T07:22Z

Ruling: the maintainer approved deleting the legacy ref in the project thread (「旧分支同意删除」, 2026-11-02 04:19Z). They deleted refs/heads/mailbox/os-justin (was e4bd21fad693be781d49086bc6892b5c7a767faa) in the GitHub UI and confirmed it there at 07:21Z (「已经删除了分支」).
Read back: git ls-remote origin refs/heads/mailbox/os-justin returns nothing at 2026-11-02T07:22Z.
State: the three per-login mailboxes were already closed (migration note 6562702845), and no successor is owed (release 6567285842). Nothing remains on this card, so it closes as completed and leaves the decision box.

Ruling: batch #452 item 3 · letter 删 · maintainer 「#452 其他同意」 2026-11-02T08:49Z

Director seat (第 56 场; brief-claimed above in 6568376875 and presented in the 总监决裁 thread as batch #452 item 3: delete or keep the legacy ref refs/heads/mailbox/os-justin). The maintainer's answer is 「同意」 for the remaining items of the batch, which for this item is 删, the seat's recommendation. The maintainer had already answered the same question in the project thread (「旧分支同意删除」, 04:19Z), deleted the ref in the GitHub UI and confirmed it (07:21Z), and domain:devx#2 read it back empty and closed the card completed (6571489034). This comment records the batch ruling for the ledger; nothing further is owed.
