* Increase shell readiness timeout to match daemon barrier
Slow interactive rc files can take longer than 1.5s to initialize. Raise
the startup command readiness timeout from 1.5s to 15s to match the daemon
barrier and prevent queued commands from executing mid-startup.
* fix(terminal): keep a quick command queued until its own spawn takes it (STA-4876)
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.
* fix(terminal): guard the queued-startup wiring the review found untested
Follow-ups from the final review pass on this branch.
- Collapse the ownership + one-shot decision into `createQueuedStartupConsumer`
so the call site is a single call rather than inline logic no test could
reach. Two mutants survived the whole suite before this: relaxing ownership to
a truthiness check, and dropping the one-shot guard. Both now fail.
- Rewrite the throwing-consume test. It asserted `updateTabPtyId` had been
called, which runs *before* the callback, so it passed with the try/catch
deleted. It now asserts the throw does not escape into the connect promise,
which is the invariant the try/catch actually provides.
- Correct the `onQueuedStartupSpawned` docblock. It claimed the callback is "the
first moment the command is guaranteed to reach a shell"; the diff's own caveat
says otherwise, since Windows runs an argv-embedded command before this fires
and a POSIX shell can die before the shell-ready write. It marks a live shell,
not delivery.
No behavior change: the consumer is the same predicate and the same one-shot,
moved behind one exported seam.
* fix(terminal): roll shell wrapper isolation into a fresh daemon
* Revert "Increase shell readiness timeout to match daemon barrier"
This reverts commit 6ab273ef36.
* Condense queued startup spawn comment
Simplify the multi-paragraph explanation into a concise summary that captures the key points: spawn must wait until after the pane is bound to preserve the worktree from force-parking, and the behavior differs between POSIX and Windows for delivery timing.
* fix(terminal): prevent consuming replaced queued startup commands
When a queued startup is replaced before the pane's first spawn,
the one-shot guard alone still allows consuming the replacement.
Add isStillQueued callback to verify the slot still holds the
originally captured command (STA-4876).
