The fork button on a stopped assistant message was inert. Frozen
interrupted nodes carry a flow-ordering seq of turnEnd.seq - 0.9, and
session.fork takes a non-negative integer on the wire, so every such
request was rejected as invalid-params before reaching the host — where
an aborted turn's logged turn/end has always made it forkable.
SessionsService.fork floors atSeq at the wire boundary. Flooring stays
inside the anchor's own turn (every turn opens with turn/start), so the
host's first-turn/end-at-or-after cut still closes on that turn.
The PTY capture does continue past the terminal-takeover bytes with the
fatal diagnostic; only the reset never follows. State that precisely in
both notes.
Document on FailLoudProcess.exit that callers treat it as the end of the
run, matching how the release path already relies on it.
Review of the previous commit found two defects in the release path, both
reproduced against the implementation:
- The timeout guarding a never-settling release was unref'ed. An
unhandledRejection listener suppresses Node's default fatal exit, so with
nothing else referenced the process reached an empty event loop and exited
0 on the very failure it was reporting. Keep the timer referenced and clear
it once the race settles.
- The handler uninstalled itself before awaiting the release. A second
concurrent rejection then became uncaught and killed the process
mid-teardown, stranding exactly the terminal state this restores. Replace
the uninstall with a latch: the first rejection is the reported one, and
later rejections (teardown's own included) fall through to the pending exit.
Add the PTY regression the fake-process tests cannot express: boot the shipped
tree over a fixture whose llm-pi-ai providers value is list-shaped, expect exit
1, and assert the captured bytes carry both the diagnostic and ESC[?2004l.
Against the pre-fix source the stream ends at ESC[?2004h ESC[>7u ESC[?u ESC[c
with no reset and the case fails, so it pins the actual bug.
Split the two-shape formatting test into one install per case; a latched
handler reports once by design.
A dsh launch whose config failed validation returned the user to a broken
shell: typing was invisible and the next command was mangled by a stray
Device Attributes reply (1;2;4cecho ...).
The Loader mounts entries concurrently, so ui-tui can already hold the
terminal (raw mode, bracketed paste, keyboard protocol, plus an in-flight
DA query) when a sibling entry rejects on its own config. installFailLoud
wrote its diagnostic and exited immediately, so nothing disposed the tree
and ProcessTerminal.stop() never ran.
Give installFailLoud an optional release teardown, awaited between the
diagnostic and the exit and bounded by FAIL_LOUD_RELEASE_TIMEOUT_MS. The
TUI launcher passes one that disposes the root context, reaching the same
shutdown() the /exit path already uses (drainInput() + ui.stop()). The
context is captured in boot()'s prepare hook because the rejection arrives
while boot() is still in flight.
Bins that pass no release keep the previous behavior exactly.
Review findings from ds-review-bot: closing the loading picker now
aborts the scan through the AbortSignal both query methods accept, a
signal-ignoring backend's late settlement is dropped by a staleness
check, one catch spans listing and projection so a projection failure
closes the overlay instead of stranding the loading placeholder,
setCandidates clears a stale still-loading error, and the batch
comment no longer overstates the win as scaling with session count.
The mount fixture always listed the session, so the case named "no list
summary" actually exercised a row proving non-blank. An omitSummaryRow
option drops the row, and the three cases now pin blank:false, an absent
row, and the summary-proven blank open.
