* fix(terminal): make Codex restart replace the pane's process instead of reattaching it A spawn for a pane that still has a live process is treated as a reattach. Both Codex restart paths raced that: the open-pane restart killed the old PTY without waiting and then spawned, and the unmounted-tab restart spawned before killing. Either way the "fresh" spawn could re-adopt the old Codex (dialog comes back) or hit the half-killed session and leave a plain shell. pty:spawn now accepts replacesPtyId. Main stops that PTY and waits for the exit before the spawn resolves the pane owner, so the existing dead-owner path launches fresh and records the current Codex home. Both restart paths send it and no longer kill the old PTY themselves. Fixes #18174 * fix(terminal): send the replaced PTY once and keep the hidden-pane replacement Two follow-ups to the restart handoff: - The replaced PTY id rode the transport options, which outlive the first spawn. A later fresh spawn from the same pane (for example a hibernation wake) re-sent it, so main stopped that id again; SSH relay ids restart at pty-1, so it could name another pane's PTY. It is now a connection input consumed by the first fresh spawn only. - The hidden-tab restart still treated a changed binding after the spawn as a reason to stand down and reap the replacement. Main has already stopped the old PTY by then, so its exit can clear the tab binding (a background-launch exit observer does) or a pane can mount, and standing down left the pane with no process. It now keeps the replacement unless the tab or leaf was actually taken over. * fix(terminal): hold the pane while a restart stops its old process A restart spawn stopped the pane's old process before reserving the pane, so a hidden tab revealed during the stop could reattach the dying process (and the restart could then join that reattach and return the old id). The replacing spawn now reserves the pane before the stop, so any spawn for the pane in that window joins the replacement; a failed stop still settles the reservation. The hidden-tab restart also tombstones the old PTY's buffered exit before spawning, so a reveal mid-restart reconnects by pane identity instead of replaying that exit into the pane. * fix(terminal): label a restart's replaced-PTY exit and keep its stop owed until sent Main now marks the PTY it stops for a replacing spawn and stamps `replacedByRestart` on that PTY's exit (provider-observed, synthetic, and SSH-unregistered stops all reach the renderer through the same finalize step). A failed stop clears the mark with nothing sent; an undelivered mark expires. The renderer classifies the labeled exit before any consumer runs: parked-tab watchers end their subscription instead of collapsing the leaf or closing the tab, the pre-attach buffer discards instead of queuing a death for a later mount, and a mounted pane treats it as an intentional restart. With that, the hidden-tab restart no longer tears down its parked watchers and buffered output before spawning; it releases them only after the swap, so a stop that fails leaves the still-running Codex fully observed. The visible restart's pane session now holds the replaced PTY until a spawn request actually carries it (the IPC transport claims it as it sends). If the pane is closed or parked first, disposal stops that PTY with an ordinary kill instead of orphaning it. * test(terminal): type restart test fakes and merge a duplicate import Co-Authored-By: Claude <noreply@anthropic.com> --------- Co-authored-by: Claude <noreply@anthropic.com>
