Reconnecting an SSH-backed workspace added terminal panes the user never opened, and the remote host accumulated shells nobody was using — one report went from 2 to 19 to 20 relay PTYs across three reconnects (STA-3077). Two root causes, both in the store. Reattach could create UI. `persistPtyBinding` has four creating branches — mint a tab, mint a root leaf, split the root and graft a leaf, mint a layout. All four are load-bearing for `pty:spawn`, which can beat the renderer's debounced layout writer, but none of them is appropriate on reattach, where the pane either already exists or is gone for good. Add `mayCreate`, defaulting true so the spawn path is untouched; every creating branch already sets `terminalMembershipChanged`, so refusing is a check rather than a new code path. Lease identity had no pane key. `upsertSshRemotePtyLease` matched on `(targetId, ptyId)` alone, so a pane that re-leased under a new relay id left its predecessor live with nothing to retire it, and the next reattach fanned out over both. One pane now keeps at most one live lease. Superseded leases are marked `expired` rather than terminated: losing a lease is not proof the shell died, so the remote process is deliberately left running. Tests assert observable behavior rather than mechanism, so they stay valid under any implementation that fixes this. Co-authored-by: Orca <help@stably.ai>
