A user message sent mid-turn (CLI busy_input_mode=interrupt, gateway priority
redirect, ACP redirect) goes through AIAgent.redirect(), which during tool
execution degrades to steer() + request_yield() on the tool worker threads.
The local terminal backend's foreground wait honours the yield (adopting the
process into the background registry), but ProcessRegistry.wait() — the
process_manage(action='wait') path — never checked it: a model sitting in a
wait on an already-background process parked the user's message for up to the
full wait window (default 180s, clamp allows more).
wait() now consumes a pending yield on its own thread each poll pass and
returns status "interrupted" with process_running=true and a note telling the
model to respond to the user; the process is untouched and still
notify-tracked. The plain-interrupt and timeout paths are unchanged.
Live repro: on origin/main, request_yield() against a thread blocked in
wait(timeout=12) had no effect (wait ran to timeout); after this change the
wait releases in <1s with status=interrupted, process still running.
Port of MoonshotAI/kimi-code#3697 ("let steer interrupt background task
waits") adapted to Hermes' per-thread yield mechanism from 463292351f.
process(action='wait') hitting its window returned status='timeout'
with a terse note — models read it as an error and re-issued identical
waits (process is the #1 exact-duplicate tool call in production: 511
dupes in a 400k-msg window; wait is 57% of all process actions).
The timeout result now carries:
- process_running: true — machine-readable 'this is a status, not a
failure'
- an explicit note: 'Wait window of Ns elapsed — the process is still
running. This is not an error. Uptime: Ms.' plus the right next step:
when notify_on_complete is set, 'you will be notified on exit — do
more work instead of waiting again'; otherwise a pointer to
notify_on_complete for next time.
- the clamp note (requested > max) now composes with the status note
instead of replacing it.
Exited/interrupted results are unchanged.
