One SSH pane accumulated one extra reattachable lease per relay restart (2, 3, 4, 5, 6 across five), and every one of them costs a `pty.attach` round trip on every later connect, forever. Nothing prunes `sshRemotePtyLeases`, so the fan-out only grows. `supersedeSiblingLeasesForPane` is fenced on the PTY the pane is durably bound to, and `durablyBoundPtyIdForPane` read `state.workspaceSession` (local) before `workspaceSessionsByHostId['ssh:<target>']`. But `persistPtyBinding(binding, hostId)` updates ONLY the host partition: AFTER-PERSIST local= ssh:t@@pty2:old:1 host= ssh:t@@pty2:new:1 So for the length of a reconnect the local copy still names the predecessor, the fence resolved to it, supersession took an already-`expired` lease as its winner, and returned having marked nothing. Both partitions agree again once the renderer republishes its layout, which is why the settled store looks consistent and hid this. Read both partitions as an ordered list, target's own first, and test the fence by membership rather than by equality with whichever was read first. Pick the winner preferring a lease this client still has a route to, since the stale partition names an expired one. Never retire a lease that is both bound and live, so a partition disagreement can't strand a running remote process. Superseded predecessors stay `expired` and are never `terminated`: losing a lease is not evidence the shell died (docs/reference/ssh-execution-boundary.md). A pane with no binding is skipped rather than pruned, so a genuine orphan stays askable. Also re-runs supersession from the binding side after each spawn commit's binding write, so the lease/binding order at a call site no longer decides, and reconciles every pane for a target immediately before `reattachKnownPtys` reads the set it feeds to `pty.attach` — that repairs stores which already accumulated these rows. The guard suite could not catch this: every assertion bound the pane BEFORE upserting the lease, an order no caller uses. Rewritten to the spawn commits' real order (lease, then binding, then the binding-side trigger); it fails 8 assertions without this change. Added a suite that drives the real `persistPtyIpcSpawnCommit` rather than the store primitives, including the exact stale-partition state written by production's own binding writer. Verified on the Docker SSH lane: five `relay.js` SIGKILLs with recovery between each, reattachable leases flat at one per pane. Note: this bounds the reattach SET, not the store. `sshRemotePtyLeases` still has no cap or TTL and rows still accumulate; pruning is left alone deliberately, since an `expired` row without `supersededBy` is a genuine orphan and must not be dropped on age.
