SSU-WEI HUANGandGitHub 0f7a3da68b feat(cursor): mid-turn Steer via concurrent ACP session/prompt (#888) (#1609)
* feat(shared): steer capability gates and live steered signal schemas

- STEERING_SUPPORTED_FLAVORS / isSteeringSupportedForSession gate which
  agents can deliver queued messages into the active turn (pi, codex,
  cursor ACP; legacy stream-json cursor excluded)
- AgentState.steeringActive, DecryptedMessage.steered and
  messages-consumed  live signal (never persisted by the hub)

* feat(cli): queue reservations and steered messages-consumed option

- MessageQueue2 gains takeByLocalId/restoreReservation/
  beginReservationDispatch/commitReservation so an async steer can reserve
  a queued row without racing the main loop's turn/start drain
- emitMessagesConsumed accepts steered: true to mark mid-turn delivery

* feat(codex): mid-turn steer via app-server turn/steer (#888)

- CodexAppServerClient.steerTurn + TurnSteerParams/Response types
- CodexRemoteLauncher registers the steer-queued-message RPC handler:
  reserves the queued row, validates it against the active turn (no
  control commands, matching mode hash), injects via turn/steer with an
  epoch guard that invalidates in-flight steers on abort/cleanup
- steeringActive agent state tracks the active-turn window
- hub syncEngine gate opens to codex; messages-consumed relays steered

* feat(web): Steered badge and steer gating for codex sessions

- HappyUserMessage shows a ↳ Steered badge fed by the live
  messages-consumed steered signal, preserved across server echoes and
  refetches (mergeMessages carries the optimistic marker)
- SessionChat gates canSteer via isSteeringSupportedForSession instead of
  the pi-only check
- clearStaleQueuedStatus normalizes a queued status on an invoked message
- fix(web): drop duplicate showSessionSummaryInChat in markdown test
  (upstream typecheck breakage)

* feat(acp): split request dispatch from completion and add soft steer

- AcpStdioTransport.sendRequestWithDispatch separates stdin-accepted
  dispatch from the JSON-RPC response, keeping sendRequest behavior
  unchanged
- AcpSdkBackend tracks concurrent session/prompt requests with an
  activePromptRequests counter (main prompt + soft steers); response
  completion stays pending until every concurrent prompt settles
- beginSoftSteerPrompt kicks off a concurrent session/prompt (Cursor GUI
  Send semantics — no cancel, no handler swap) returning {dispatched,
  completed}; softSteerPrompt awaits the full response for direct callers

* feat(cursor): mid-turn soft steer via concurrent session/prompt (#888)

- CursorAcpRemoteLauncher registers the steer-queued-message RPC handler:
  reserves the queued row, rejects control commands and mode mismatches,
  then soft-injects via beginSoftSteerPrompt without canceling the
  in-flight turn
- Acks the hub once stdin accepts the inject (not on turn completion) to
  stay inside the 30s RPC window; the launcher stays busy until the
  concurrent prompt settles so handlers are not swapped mid-inject
- steeringActive agent state mirrors the active-turn window; abort and
  cleanup reset it and invalidate pending steers
- Legacy stream-json Cursor sessions register a steer handler that
  reports unsupported

* fix(codex,shared): address bot findings on steer gate and ambiguous turn/steer

- STEERING_SUPPORTED_FLAVORS / isSteeringSupportedForSession advertise
  codex and pi only; cursor joins when its soft-steer handler lands (#1609)
- turn/steer now splits dispatch (stdin accepted) from completion (turn
  finished): the hub RPC acks once dispatch succeeds — never on the
  concurrent turn's completion, which can exceed the 30s RPC window
- queue row commits only after the turn settles; a rejected/aborted steer
  restores the row so the message still delivers via turn/start, and a
  dispatched steer is never restored (no duplicate delivery)
- steer carries clientUserMessageId (echoed as userMessage.clientId) so
  ambiguous transport failures can reconcile the thread later
- client tests cover dispatch/complete split and stdin-write failure

* feat(shared): advertise cursor in the steer gate now that its handler lands

Cursor ACP sessions pass the web and hub steer gates; legacy stream-json
cursor sessions stay excluded.

* fix(codex): reconcile dispatched steers before restoring; align error copy

- A dispatched turn/steer whose completion fails (disconnect / protocol
  error) is now reconciled via thread/read by clientUserMessageId before
  the queued row is restored — the instruction is only re-delivered by
  turn/start when the thread never received it
- Reconcile targets the pinned steer thread, not whichever turn is
  current when completion fails
- syncEngine unsupported-flavor error now matches the capability gate
  (Pi and Codex only until the cursor handler lands)
- launcher tests cover steer success (ack on dispatch), reconcile-accepted
  and reconcile-rejected outcomes

* fix(codex): consume the row at dispatch; drop background reconcile

- The hub RPC acks and the queue row is consumed as soon as stdin accepts
  turn/steer; completion is background-only logging. A dispatched steer is
  never restored, so the same localId cannot be re-delivered via turn/start
  after the caller was told the steer succeeded
- Dispatch failure (stdin write error) still restores the row and reports
  failure
- steer.completed rejection is always handled (no unhandled rejection on
  the dispatch-failure path)
- tests updated: completion failure after dispatch keeps the row consumed;
  dispatch failure restores it

* fix(cursor): consume the row at dispatch; keep waiters for prompt gating

- The hub RPC acks and the queue row is consumed as soon as stdin accepts
  the concurrent session/prompt; completion is background-only. A
  dispatched steer is never restored (no duplicate via the next prompt)
- softSteerWaiters are registered before awaiting dispatch so the main
  loop's finally cannot start the next prompt mid-inject; they still gate
  prompt handover on completion
- tests updated: post-dispatch ACP rejection keeps the row consumed

* fix(cursor,hub): never hang teardown on unresolved soft steer; align diagnostics

- Prompt-finally waits for soft-steer completion only when not exiting;
  the outer finally no longer waits at all — cleanup() disconnects the
  ACP transport, which rejects pending requests and settles the waiters
- syncEngine gate diagnostics and JSDoc name all supported flavors
  (Pi, Codex, Cursor ACP)
- regression test: Switch with an unresolved soft-steer completion still
  reaches teardown

* fix(codex): distinguish definite rejection from indeterminate completion

- Transport-level failures (timeout, abort, disconnect, spawn, protocol)
  carry an indeterminate marker; explicit JSON-RPC error responses do not
- After a dispatched steer, turn completion resolves → commit + consumed;
  a definite app-server rejection restores the row (instruction was never
  accepted, so turn/start cannot duplicate it); an indeterminate outcome
  leaves the row reserved so it can never be delivered twice
- Completion handling registers before awaiting dispatch so the
  dispatch-failure path cannot leak an unhandled rejection
- client/launcher tests cover explicit rejection (restore), indeterminate
  outcome (row stays reserved) and dispatch failure

* fix(codex): reconcile indeterminate steers instead of a permanent reservation

- After an indeterminate completion (disconnect/protocol), reconcile the
  thread by clientUserMessageId immediately: accepted → commit + consumed,
  provably rejected → restore, still unreadable → keep the reservation and
  retry from the main-loop top on later passes (post-reconnect)
- A row never sits in dispatching forever: the hub cannot stamp it invoked
  while the instruction may never have been accepted
- tests: indeterminate keeps reserved while thread unreadable; accepted
  reconciliation consumes; rejected path restores

* fix(cursor): abort drops soft-steer waiters so the next prompt never blocks

- Ordinary Abort (shouldExit false) now clears softSteerWaiters: the
  prompt finally cannot wait forever on a soft steer whose completion is
  unbounded; the ACP cancel rejects in-flight requests, and cleanup()
  settles leftovers on session end
- regression test: unresolved soft-steer completion after Abort no longer
  blocks the next prompt

* fix(codex): accept all thread item shapes; retry reconcile; ack through abort

- Reconcile matcher accepts userMessage/user_message with clientId/
  client_id, matching the shapes the thread parser supports — an accepted
  steer can no longer be misclassified as rejected
- A pending reconciliation schedules a wakeLoop retry, so a temporary
  app-server outage cannot strand the reservation behind waitForTurnOrRecovery
- The success-path ACK no longer checks the steer epoch: the hub already
  reported steered on dispatch, so commit + messages-consumed must reach
  it even when an abort resets the queue in between

* fix(cursor,acp): abort force-settles soft-steer bookkeeping

- AcpSdkBackend.abortSoftSteers() drops the concurrent-prompt counter and
  notifies response-complete so the next turn's waitForResponseComplete()
  cannot block on a soft steer that will never settle after abort
- handleAbort calls it before clearing the waiters; the main prompt's own
  finishPromptRequest stays guarded by Math.max(0, ...)
- unit tests cover counter release and no-op when idle

* fix(codex): reinit reconnected app-server; keep reconcile retries alive

- thread/read after a disconnect auto-connects a fresh app-server, which
  must be initialized before any request — reconcile now ensures
  connect + initialize (isConnected getter added to the client)
- every still-unknown loop-top reconciliation schedules the next retry,
  so recovery without external traffic is eventually observed
- launcher mock gains isConnected

* test(acp): match finishPromptRequest epoch signature in whitebox test

* fix(codex): timer-driven reconciliation; init tracking; abort-safe ACK

- Reconciliation runs on a self-rescheduling 1s timer independent of the
  main loop (wakes it too), so idle loops and waitForTurnOrRecovery still
  observe app-server recovery; abort clears nothing implicitly — the ACK
  path commits and consumes even when the reservation was cancelled
- Absence of a durable client id is ambiguous: unmatched reads stay
  'unknown' and keep retrying instead of restoring the row
- CodexAppServerClient tracks initialized state (reset on disconnect/exit)
  so ensureAppServerInitialized re-initializes a fresh process before
  thread/read; initialize failures leave the flag false for the next retry
- tests: accepted reconciliation via scheduled timer, indeterminate
  keeps reserved, explicit rejection restores

* fix(codex): bind reconciliation to the launcher lifecycle

- runSteerReconciliation clears any armed retry timer on entry and never
  installs a second one, so loop-top and timer-driven passes cannot
  multiply
- shuttingDown is set when the main loop ends: timers are cleared and the
  pending map is dropped, so an unresolved steer can never respawn an
  app-server after cleanup (remote-to-local switch included)

* fix(cursor): abort releases an in-progress soft-steer wait

- The prompt-finally wait races Promise.allSettled against the abort
  signal: an Abort that clears the waiters now also releases a wait that
  already started, so the launcher always reaches the next queued prompt

* fix(codex): report steered only after app-server acceptance

- The handler now awaits steer.completed (the inject-acceptance response):
  an explicit JSON-RPC rejection surfaces as failed and restores the row
  for the normal turn/start path instead of a false steered
- Transport failure after dispatch reports 'Steer outcome is being
  reconciled' and keeps the row reserved while the timer-driven thread
  reconciliation runs
- dispatch-failure path also swallows the paired completion rejection

* fix(cursor,acp): commit on ACP acceptance; distinguish transport failures

- AcpStdioTransport marks transport-level failures (timeout, closed,
  stdin write) as indeterminate; explicit JSON-RPC error responses are not
- The steer handler commits + consumes on completion (ACP acceptance) and
  restores the row on an explicit rejection; an indeterminate transport
  failure keeps the row reserved so a delivered instruction is never
  re-sent, and the ACK reaches the hub even when abort reset the queue
- launcher/transport tests updated for the three outcomes

* fix(steer): tri-state cancel, clear-safe reservations, bounded acceptance wait

- MessageQueue2.cancelByLocalId returns 'in-flight' for a dispatching
  steer reservation: the hub neither deletes the row nor stamps invoked_at
  (new CancelMessageResponse 'busy' status; web restores the optimistic
  row); pushIsolateAndClear and reset/close share cancelReservations so
  /clear-style commands cannot have a rejected steer resurrect a discarded
  prompt
- turn/steer acceptance wait bounded at 25s (< hub 30s RPC timeout): a
  lost response is indeterminate and funnels into thread reconciliation
  instead of stranding the reservation
- tests updated for the tri-state cancel contract

* test(cursor): match tri-state cancel contract for dispatching steers

* fix(cursor): drop duplicate promptInFlight declaration after upstream merge

* fix(codex,web): busy-aware edit flow; bound reconciliation reads

- QueuedMessagesBar edit flow treats a 'busy' cancel as unsuccessful: it
  never prefills the composer when the row is inside an async steer, so a
  second client cannot send a duplicate
- reconcileSteerByClientId bounds thread/read with a 5s timeout so a
  connected-but-silent app-server cannot hold the reservation in-flight
  indefinitely

* fix(steer): inFlight-dominated cancel acks; bounded reconciliation

- hub cancel-queued-message acks check inFlight before removed: a stale
  duplicate socket reporting removed can no longer delete the durable row
  while another socket is dispatching the steer
- reconciliation entries expire after 60s and mark delivered: after the
  rejection window, a dispatched steer that the app-server never proved
  (client ids dropped on restart) is committed instead of polling
  thread/read forever
- pre-dispatch failures (abort before write included) never enter
  reconciliation — they restore the row and report failure

* fix(cursor,acp,web): indeterminate close marks, steer gating precision

- AcpStdioTransport.rejectAllPending marks close/protocol failures
  indeterminate, so an accepted-but-close-interrupted soft steer restores
  nothing (no duplicate delivery)
- the abort race in the soft-steer wait removes its listener in finally
  (no accumulation across repeated waits)
- SessionChat gates the Steer button on agentState.steeringActive for
  codex/cursor instead of the queued-grace thinking flag, so Steer is not
  exposed before the launcher can accept it
- codex pre-dispatch abort never enters reconciliation (merged from #1606)
