KNOWN RED (`it.fails`), no product change. Found while verifying the close retraction fix: once the emptying actually reaches paired clients — a state the previous behaviour never allowed, because nothing propagated — re-adoption of a later create is flaky. Measured 1 failure in 6 runs of the two-client journey. `decideWebSessionTabsSnapshot` treats the host's synthetic `removed:<t>` retraction as a publisher handover: it retires the still-live renderer epoch and installs the retraction as current, while the removal also clears the live freshness record. The next frame from that same running publisher then matches no lineage and reads as a retired generation, so it is outranked and the publisher is locked out of the worktree until its generation changes. `local-structured-session-tabs-sync/snapshot-apply.ts` documents this exact scenario and has a revive escape; the mirror path has none. The suffix case explains the 1-in-6: `hasRetiredValue` is an exact string match, so a republication carrying `:headless-merge:` walks past the fence and only a bare same-epoch republication is locked out. Not fixed here on purpose. Dropping the retirement makes the red case pass but breaks `web-session-tabs-sync.test.ts > keeps a removed worktree fenced against delayed predecessor epochs`, which asserts a same-epoch higher-version frame after a removal must be rejected. At this layer those are the same frame — this function holds no `receivedFrame`, so it cannot separate a delayed predecessor from the live publisher speaking again. The fix belongs in `shouldApplyRecoveredWebSessionTabsSnapshot`, which does hold that ordering and currently defers to the same epoch fence. That is a contract change across two functions and an existing invariant, not a one-liner.
