The fourth eviction trigger on `expiredGenerationByPane`, and the reason it is not redundant with the three already there or with the two other agents' guards on this same map. A verdict records that a pane's 15s handle-gap wait ran out. Nothing retires it when that pane subsequently publishes its handle, so the NEXT gap on that pane gets no wait at all — #19735 with the bounded wait removed rather than merely shortened. Measured on the reconciled union tree (1b621b6b13) plus the outage guard: the verdict still answered `true` after the handle landed, and the second gap resumed with zero panes parked. Why none of the existing rules reach it, each checked rather than assumed: - superseded generation: #19647 in this same stack stops recording `status: null` for an unreachable host, so the generation no longer moves across an outage on one runtime. - dead tab row: the row stays published throughout. It is the HANDLE that comes and goes — that is the definition of the gap. - removed environment: the environment is still here. - read-time pane identity (adv2-skew,cdafc90d8f): the pane keeps the same layout binding across the gap BY DESIGN, and the union suite pins that a genuine reattach to the same PTY must inherit. That check discriminates a different pane behind one tab id; this one discriminates a later gap on the same pane. - contact lost (adv3-journeys,2da662424b): no outage is involved; this is a healthy connection where the host was simply slow once. Composition proven by mutation on the union tree, four disjoint kills: dropping this drain kills 2 tests and only mine; dropping the re-park worktree kills 1 and only mine; dropping the contact guard kills 1 and only theirs; forcing the contact guard always-true kills 16 across every suite. No mutation kills another agent's test, so these are three guards on three holes, not three on one. Also carries `worktreeId` across a re-park: adopting an orphaned terminal re-keys `tabsByWorktree` without re-keying the record, so a live wait kept releasing on retraction evidence about the workspace it was no longer about. The park-time `paneBinding` deliberately does not move with it — that is the pane's identity, this is only where its rows are filed.
