Problem

A Claude thread showed "working" for 20 minutes after the agent was done. Nothing was sent to Claude, and only Stop ended it.

The provider log showed the sequence:

A background command finished mid-turn.
Claude ended the turn, then opened a wake turn (system init). T3 buffered that frame and queued a "Background task completed" continuation run.
1.2 s later a queued user message started, and Claude folded it into the wake turn it had just opened. That turn's output and its one result went to the user run.
When the continuation run started (90 minutes later, behind other queued runs), it replayed the stale buffered init. That marked the wake as started, which skips both the empty-buffer settle and the 2-minute "wake never opened" fallback. No result could ever arrive, so the run stayed running.

Fix

Claude runs one root turn at a time. When a root result ends a user turn while a wake is still open in the buffer (a root frame after the last buffered result), the adapter marks that wake as absorbed. The continuation replays every buffered frame as before, so the wake's assistant output, tool calls and workflow launch results stay in the transcript. It then settles instead of waiting for a result. A root frame buffered later starts a new wake and clears the mark. A wake that finished on its own keeps its result in the buffer and replays as before.

Verification

ClaudeAdapterV2.test.ts: "settles a continuation whose wake turn a user turn absorbed" buffers wake assistant text before the user turn. On main it times out because the continuation never settles. With the previous drop-frames version it fails because the wake text is lost. With this fix it completes and the text is in the transcript.
All 293 Claude adapter tests pass. The server typecheck, lint and format are clean.
Not reproduced with a live Claude session: the race needs a background task to finish within about a second of a queued message starting. The sequence above comes from the real provider log of the affected thread.

🟡 Medium Adapters/ClaudeAdapterV2.ts:5442

When a user result drops the absorbed wake frames, it also deletes buffered subagent assistant and user frames, so the continuation replays the surviving task start without the child's conversation or tool activity. The filter retains only task-related system messages after wakeStart; preserve frames with a non-null parent_tool_use_id as well.

No longer relevant as of 48c1e2f54db2f6ec3374ad4604278b3efe65cf8b

Note

Written by claude-opus-5-5 on behalf of Maria

Fixed in 48c1e2f5. Frames with a parent_tool_use_id belong to a background subagent, not the absorbed root turn, so the prune keeps them along with task system frames.

MmacroscopeappBot10d ago

48c1e2f5 addresses this, but it isn’t in the branch snapshot I can see yet.

Approvability

Verdict: Approved at b2994f1

Macroscope's review found this PR approvable — The adapter now completes absorbed background-wake continuations after replaying their buffered output, rather than waiting indefinitely for another result. The change is limited to wake lifecycle bookkeeping and preserves transcript and workflow frames.

Walkthrough

ClaudeAdapterV2 tracks wake output absorbed by a user turn. A later continuation consumes that state and can finalize immediately. A regression test covers the user turn completing before the continuation completes with the wake assistant text in the event stream.

Changes: Claude absorbed-wake continuation

Layer / File(s)	Summary
Track absorbed wake state and complete continuations `apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts`, `apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts`	The adapter marks wake output absorbed when a non-continuation result is followed by buffered root-turn frames. It clears the marker when root-turn frames arrive or wake state is cleaned up. A continuation consumes the marker and finalizes immediately when the wake was absorbed. The regression test covers the user turn and later continuation.

Settle absorbed subagent wakes without using the opaque-task shortcut.

A subagent notification can offer a continuation before the wake init arrives. The user-turn result then removes that init but retains the notification. Replay has no result, and subagent IDs do not enter the opaque replay-tombstone set, so settlement waits for the two-minute deadline.

Track an absorbed-wake signal separately from opaque tombstones. Scope it to the root frame removed by dropAbsorbedWakeFrames, and clear or consume it before a later wake can reuse the buffer. Settle immediately only while context.nativeWakeStarted is false; a later root frame must still be allowed to open its wake. Extend the existing test with the subagent sequence and the late-root case.

Note

Written by claude-opus-5-5 on behalf of Maria

Leaving this as a known limit. In that sequence the continuation drains the kept subagent notification, never sees a root frame, and settles through the existing 2-minute "wake never opened" fallback. That is bounded, unlike the open-ended hang this PR fixes. Settling it immediately would need a separate absorbed-wake signal and its own lifecycle, which is more machinery than the edge case warrants here.

CcoderabbitaiBot10d ago

@maria-rcks Understood. In this sequence, the existing two-minute fallback settles the continuation if no root frame arrives. That is a bounded delay, not the open-ended hang this PR fixes.

I accept leaving this as a known limit for this PR. No separate absorbed-wake state is needed here.

Would you like me to open a follow-up issue for the bounded delay?

10	I like ambitious ideas, simple systems, and software that feels obvious. Do not preserve complexity just because it already exists. Do not introduce machinery because it looks architecturally impressive. Understand the real constraint, then fight for the smallest model that makes the correct behavior unsurprising.

b2994f12 also settles this case right away. The continuation settles once replay finishes instead of waiting on the 2-minute fallback.

CcoderabbitaiBot8d ago

@maria-rcks Confirmed in the supplied code. markAbsorbedWake records absorption independently of opaque-task tombstones. The continuation consumes that marker and settles after replay, without waiting for the two-minute fallback. A new buffered root frame clears the marker so a later wake can proceed.

This addresses the bounded-delay finding. No follow-up issue is needed.

Apply the completion for a task whose start is still buffered.

On the active-turn path, a live task_notification for a task that is not registered is dropped. dropAbsorbedWakeFrames keeps the buffered task_started for that task. When replay registers the start, the task is marked running, and no completion is applied afterward. The task can remain running.

The retained start is needed for replay, so the filter should keep it. The defect is in the notification path. The completion is discarded there before the buffered start is replayed. Preserve the completion with its start: buffer the notification with the start, or apply it after replay registers the start.

A live task_notification for a task whose task_started is still buffered is dropped on the active-turn path no matter how the wake ended: on main it can happen whenever a user turn runs between buffering and the drain. This PR does not change that path. With b2994f12 the start replays the same way it does on main, so this is not a regression, and fixing the notification path belongs in its own change.

CcoderabbitaiBot8d ago

@maria-rcks Agreed. The completion loss occurs on the active-turn notification path, independently of absorbed-wake handling. Retaining the buffered task_started is not the cause.

I withdraw this finding from this PR. The notification-path fix can remain a separate change.

Would you like me to open a follow-up GitHub issue?

Preserve workflow launch results.

If an absorbed wake launches a workflow, its root user tool result has a null parent and can be removed here. That result carries transcriptDir and runId. The retained task_started and task-progress frames can still register and replay the workflow members, but they do not carry the filesystem handles. Without transcriptDir, member transcript reads are skipped. Retain and apply the launch metadata without reopening the absorbed wake.

Fixed in b2994f12. Nothing is pruned now, so the root tool result that carries transcriptDir and runId replays through the normal path in the continuation.

CcoderabbitaiBot8d ago

@maria-rcks The supplied code confirms the fix. markAbsorbedWake preserves the buffered frames, so the continuation replays the root tool result through the normal workflow metadata handler. The wakeAbsorbed check then settles the continuation after replay.

Preserve buffered assistant output.

If a wake emits assistant text or a tool call before the user turn starts, the adapter buffers it without projecting it. This filter deletes that output when the user turn ends, so it never appears in either turn’s transcript.

Project the buffered output without reopening the wake. Add a regression test with assistant output before the user turn.

Fixed in b2994f12. The adapter no longer drops any frames. It marks the wake as absorbed when the user turn's result arrives. The continuation replays every buffered frame, including the wake's assistant text and tool calls, then settles because no result will come. The absorbed-wake test now buffers wake assistant text before the user turn and asserts it reaches the transcript. That assertion fails on the previous head.

CcoderabbitaiBot8d ago

@maria-rcks The supplied code addresses the output-loss finding. markAbsorbedWake preserves the buffered frames. The continuation replays those frames, then uses wakeAbsorbed to settle without waiting for another result.

The reported regression assertion covers assistant text buffered before the user turn. I have not rerun the tests.
