Triggering a quick command opened a terminal tab titled with the command's
label, the shell started and drew its prompt, and the command never ran.
TerminalPane snapshots `pendingStartupByTabId[tabId]` in a useState lazy
initializer, and a mount effect deleted the entry immediately. The pane's key
is `${tab.id}-${tab.generation ?? 0}`, so anything that bumps generation before
the command reaches a shell — the stall-recovery remount fired from
`requestTerminalPaneRecovery`, or the allDead activation regeneration — mounted
a second pane that re-read an emptied slot and spawned with no command at all.
The loss was permanent, which is why every scope failed alike: repo, global and
agent-prompt all funnel through the same queue-then-snapshot sequence.
Spend the entry at `onPtySpawn` instead, which is the one point that proves this
pane's own fresh spawn exists. A pane retired mid-connect never reaches it, so
the command stays queued for the next mount; reattach skips `onPtySpawn`, so it
cannot spend a command it never delivers.
Three details are load-bearing:
- Ownership is reference identity (`paneOwnsQueuedStartup`). Setup and issue
splits borrow the same `deps.startup` field for their own one-shot payload, and
that payload can be structurally identical to the queued command, so a
truthiness test would let a split pane spend a command it never runs.
- The consume runs after `bindActivePanePty`. While the tab still has no ptyId,
the queued entry is the only thing holding its worktree out of the
retention-budget force-park, so dropping it first unmounts the pane mid-spawn.
- The callback is one-shot. `onPtySpawn` fires on every fresh spawn a pane makes,
including hibernation wake and the respawn ladder, and a command queued after
the first launch belongs to that later launch.
Known residual, documented at the call site: the consume tracks "a pty exists",
not "the command ran". Windows embeds short commands in the shell argv, so they
execute before the spawn resolves and a pane retired in that window re-delivers
on remount; on POSIX the write waits for shell-ready, so a pty that dies in that
window loses a command already spent. Closing either needs a delivery signal
from main rather than this callback. Both windows are narrow, and both are
strictly better than losing the command unconditionally.
