The host drops a worktree's entry when its last tab closes and announces it with a synthetic `removed:<t>` epoch. Both receipt sites treated that as a publication: `decideWebSessionTabsSnapshot` and `recordReceivedWebSessionTabsSnapshot` each noted the retraction epoch as current, which pushed the still-live renderer epoch onto `retired`. The removal also drops the live freshness record, so the next frame from that same running publisher matched no lineage, read as a retired generation, and was outranked. The live publisher was locked out of its own worktree until its generation changed. That is fail-closed, and it is why re-adoption after an emptying was flaky once the emptying actually reached paired clients. A retraction and the live publisher's next frame are the same epoch at a higher version, so epoch identity cannot separate them and never could. Delivery order can. `recordReceivedWebSessionTabsRemoval` now records the retraction as the worktree's newest received evidence instead of deleting the ledger, so `shouldApplyRecoveredWebSessionTabsSnapshot` — the gate every production apply path passes before `decideWebSessionTabsSnapshot` — fences a frame that reserved its received frame before the retraction while admitting one that arrives after it. The boundary carries the retraction's own epoch, which never matches a host publication, so a later live frame may still restart its version counter. `local-structured-session-tabs-sync/snapshot-apply.ts` documents the same conclusion for the local path: a retired epoch is not proof of a dead generation. `keeps a removed worktree fenced against delayed predecessor epochs` pinned the delayed predecessor at the raw decision layer, which is the same call as the live publisher's republication. It now pins the identical scenario — same epoch, higher version, still rejected — through the receive-and-apply path that actually holds the ordering, plus the composed gate as production spells it. The committed `it.fails` repro is not sufficient on its own: it records no received frame, so dropping only the `decideWebSessionTabsSnapshot` retirement turns it green while the publisher stays locked out on every real path. A receive-and-apply case is added alongside it to close that gap.
