🟠 High Adapters/CodexAdapterV2.ts:1819

When a queue-started root turn spawns a subagent before the continuation run is adopted, the child’s notifications are processed immediately while the parent’s spawn notification is held. The child’s item events and turn/completed are then dropped because no active child context exists; replaying only the saved start leaves the child turn running with missing messages and tools. The hold lookup at codexStartedTurns.get(turnId) covers only the root turn ID, so buffer descendant notifications too or register the child’s ownership before holding the parent events.

Hold native subagent events until their parent replay registers them.

If a queued root turn spawns a native subagent before adoption, the parent's spawn notification is held here. The child's turn ID is not in codexStartedTurns, so child notifications bypass the hold.

The child's turn/started enters pendingSubagentTurns. Its item notifications then exhaust awaitActiveTurn, and its completion returns without a context. When parent replay later registers the subagent, the adapter creates a running child whose reply and completion were discarded.

Retain child notifications until subagent registration, including child completion. Cover a child that finishes before root adoption.

Update the native-event hold logic around codexStartedTurns so child-turn notifications are retained until parent replay registers the subagent, rather than bypassing the hold when the child turn ID is absent. Preserve all child events, including completion, for replay after registration, and ensure a child that finishes before root adoption is still applied to the registered subagent context.

Handle the native turn when an unstarted continuation is released.

When a queued continuation ends before startTurn, releaseCodexStartedTurn deletes the pending record. This also discards the held notifications for that turn, including its completion. The function does not interrupt the turn. Codex can keep running it while T3 records none of its prompt, actions, or reply. Item-event lookups for that turn then find no active context, and a user interrupt for it fails as not active.

Decide how the release path handles the native turn before it discards the record. Either send turn/interrupt for it first, as the stalled-retry path does, or keep enough state to record it. The choice depends on whether cancelling a continuation should also stop the native work. The repository does not settle that.

Count pending Codex turns in both background-work probes.

A queue-started turn stays in codexStartedTurns until its continuation run adopts it. Neither probe checks that map. If the idle deadline expires while the continuation is still pending, the release or unload path can proceed. The held notifications are then dropped, and the queued turn is not recorded. The window is the interval between the queue-started turn and its continuation run start, so the deadline must fall inside that interval.

Signal approval waiters after the held replay completes.

For a queue-started turn, adoptCodexStartedTurn releases registered before it replays the held notifications. A waiting item/fileChange/requestApproval handler can resume at that point and read fileChangeKindsByItem before the replayed item/started sets it. An earlier held notification that suspends before that write can create this window. The approval then gets no file paths when the request has no reason or grantRoot.

Approval requests use handleServerRequest, so the notification hold does not apply to them.

Release the waiters after the replay. Use a finalizer so waiters still resume if the replay is interrupted:

Drain held notifications without repeated Array.shift.

A long turn can accumulate many token-delta notifications while its continuation waits. Removing each entry from the front of an array makes replay quadratic in the number of held notifications. Use an index or a deque while preserving the order of notifications that arrive during replay. (raw.githubusercontent.com)

Keep the started-turn entry consistent when replay is interrupted.

Line 2459 removes codexStartedTurns entry only after the replay loop finishes. The worker can interrupt the start effect through its cancellation race, which skips the delete. The entry then keeps registered completed, so the adoption check at line 2448 rejects later queue-started turns on that thread. The held-notification check at lines 1819-1822 keeps that turn's notifications queued until a release hook clears the entry.

A cleanup that deletes the entry in a finalizer must also handle notifications that have not replayed yet. Deleting the entry first would drop them, and leaving the entry in place keeps the stuck state. The correct handling of those notifications is not established by the inspected code, so this comment gives no patch.

Keep subsequent queued root turns pending during replay.

If Codex starts the next queued turn while adoption replays the previous turn's held notifications, activeTurns still contains the previous context. This condition rejects the new root turn and routes it to rememberSubagentTurnStarted. The root thread has no subagent registration to consume that entry. The next queued prompt and reply therefore remain unrecorded.

Retain subsequent root turns during replay and serialize their adoption. Add this sequence to the replay regression test.

Wait for a pending queue-started turn in the legacy approval handlers.

execCommandApproval and applyPatchApproval look up an active turn by thread and return a protocol error when none exists. A queue-started turn has no active context until its continuation run registers it. An approval that arrives in that window can therefore be rejected and never reach the user.

The legacy requests carry conversationId, not a turn ID, so the turn-ID wait used by the other handlers cannot be reused. Wait on the pending turn for that thread, then look up the active context again.

Suggested fix

Add this helper after findActiveTurnByNativeThreadId:

const awaitActiveTurnByNativeThreadId = Effect.fnUntraced(function* (nativeThreadId: string) {
  const pending = Array.from(codexStartedTurns.values()).find(
    (turn) => turn.nativeThreadId === nativeThreadId,
  );
  if (pending !== undefined) {
    yield* Deferred.await(pending.registered);
  }
  return yield* findActiveTurnByNativeThreadId(nativeThreadId);
});

Use it in both legacy handlers:

         yield* client.handleServerRequest("execCommandApproval", (payload) =>
           Effect.gen(function* () {
-            const context = yield* findActiveTurnByNativeThreadId(payload.conversationId);
+            const context = yield* awaitActiveTurnByNativeThreadId(payload.conversationId);
         yield* client.handleServerRequest("applyPatchApproval", (payload) =>
           Effect.gen(function* () {
-            const context = yield* findActiveTurnByNativeThreadId(payload.conversationId);
+            const context = yield* awaitActiveTurnByNativeThreadId(payload.conversationId);

Review comment at @apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts at line 5027:
Update execCommandApproval and applyPatchApproval to wait for a pending queue-started turn associated with payload.conversationId to register, then look up the active turn context again. Use a thread-based wait rather than a turn-ID wait, since these legacy requests provide a conversation ID.
