fix(server): a Claude Monitor line no longer wakes a delegated child's parent - #36339
The rework item said the problem still happens in the real app but not what was observed, so I ran the same flow myself: Claude Code 2.1.323, claude-haiku-5-5 parent and delegated child, fresh database from T3CODE_DEV_SEED=0 vp run dev, child arming a Monitor that prints EVENT_1..3 fifteen seconds apart. At ff06982, in 4 runs out of 4, the EVENT_1 and EVENT_2 wakes were tagged monitor/updated, started no delegated task and did not wake the parent; I also replayed raw recorded SDK frames through the adapter harness and got monitor/updated twice then monitor/completed. So I could not reproduce any per-line failure. What did still reproduce was the second half of the reported bug: the Monitor's end arrives as monitor/completed, Orchestrator.mayStartSubagentFollowup refused every monitor-kind notification, and the parent was never woken with the child's final answer. With per-line wakes now correctly tagged as monitor, a Monitor-using child went silent after its first result. This is my inference of what the verifier saw. New commit 6847120: mayStartSubagentFollowup now refuses only monitor notifications with outcome 'updated'; a Monitor that ends (completed, failed, cancelled) starts a delegated follow-up the way a background command's ending does. The parent-lock decision at dispatch uses the same predicate and follows. After the change, 2 real runs out of 2: parent woken once after STARTED and once when the Monitor ended, not for EVENT_1 or EVENT_2. Earlier commits are unchanged: 2090a54 tags a wake that starts while a Monitor runs (no task report, no due ScheduleWakeup) as monitor/updated and splits the drain so a later buffered wake keeps its own tag; 6fc0f85 and ff06982 keep the absorbed marker for a later wake left behind a split. Review state: all 35 checks passed on 6847120 and Macroscope approved it. CodeRabbit posted no rated code finding on 6847120, but its 'Out of Scope Changes' pre-merge check asks to revert the gate change or move it to a separate PR linked to #31843 or #31856. I did not revert it: without it the reported behaviour ('the parent should hear back when the child's work actually ends') does not hold in the real app. The objection is fair on scope: the gate change is the same one the open PR #31856 makes and will conflict with it; reverting 6847120 restores ff06982 exactly if the maintainers want the per-line fix alone. No new regex or parser.
Commit 9efd960 (origin/main). (1) I recorded raw Claude Agent SDK frames with the system Claude Code 2.1.323 (Haiku): a Monitor running for i in 1 2 3; do sleep 4; echo EVENT_$i; done. Each per-line event woke the session with only system/init, an assistant message and result{origin:{kind:'task-notification'}} (no task_id). Only the Monitor's end sent a system task_notification ('Monitor "line monitor" stream ended'). (2) I ran T3CODE_DEV_SEED=0 vp run dev on a fresh database, added a scratch git project, and used t3 thread start --provider claudeAgent --model claude-haiku-5-5 to start a parent that delegated one async task (delegate_task, Claude Haiku) telling the child to arm a Monitor printing three lines 15s apart, reply STARTED, then echo each event. Projection afterwards: the child's EVENT_1 and EVENT_2 wakes are user messages 'Background task completed.' with notification {source:{kind:'background_task'},outcome:'updated'}. Each started a new app_owned delegated task (3 subagent rows, all completed/delivered), and the parent got a 'Delegated task …' message and ran a turn for each. The Monitor's end came in as {source:{kind:'monitor'},outcome:'completed'}: no new delegated task, and the parent was not woken. (3) A failing adapter test on branch factory/repro-36113: a Monitor-event wake reaches continuationRequests with notification undefined, where monitor/updated is expected.
Evidence
Run the same parent prompt against fresh real servers using Claude Code 2.1.323 / Haiku 5.5. Delegate a child that arms native Monitor with for i in 1 2 3; do sleep 15; echo EVENT_$i; done, replies STARTED, echoes events, and reports MONITOR_DONE. Observe notification metadata and parent deliveries through stream end.
These images show captured server projections in a transcript viewer, not web-client screenshots. GIFs render the terminal observer capture, including history present when it attached.
Caveats retained in the evidence: the head parent initially launched a stray native placeholder agent before making the requested delegation. The base child started an unintended second Monitor after the original stream ended; its later MONITOR_DONE delivery came from that extra Monitor. The original base stream's EVENT_3 was not delivered. Both runs delivered an initial STARTED acknowledgement; the demonstrated fix concerns subsequent Monitor progress and completion.
Not shown:
No web, desktop, or mobile screen recording was taken; this proof exercises the real server and Claude provider and captures their persisted messages and delivery state.
An otherwise identical single-Monitor-only completion trace on base was not obtained: after the original stream ended, the child started an extra Monitor. The original EVENT_1/EVENT_2 parent wakes, original completion being dropped, and correct head completion delivery were directly observed.
Tests
vp test run src/orchestration-v2/DelegatedCompletionDelivery.test.ts (apps/server): 60 passed; the 'live' row of 'delivers the run a background command's wake starts after the original result' now dispatches a monitor/completed notification and fails without the gate change ('expected undefined to not equal undefined' on run.delegatedTaskId), passes with it. vp run check:changed at 6847120: pass (format, lint, knip, graphql, typecheck of 3 packages, tests in 6 files). Real-provider runs on a fresh dev database: 4 of 4 at ff06982 with per-line wakes tagged monitor/updated and one parent wake; 2 of 2 at 6847120 with parent wakes only after STARTED and at the Monitor's end. A temporary harness test replaying recorded real frames gave monitor/updated, monitor/updated, monitor/completed; it was not committed. CI on 6847120: all 35 checks passed.
A Monitor line that coincides with a ScheduleWakeup inside its early-fire margin keeps the default background_task/updated tag.
A Monitor event wake that a user turn absorbs before its result arrives, with another wake buffered behind it, is not covered by a test; the drain split handles it by finalizing the continuation at the absorbed end frame.
ProviderContinuationService's default notification (background_task/updated) for wakes with no report is unchanged.
A wake left behind a Monitor event and then absorbed by a user turn is itself tagged monitor/updated, since nothing in the buffer distinguishes it from another Monitor line.
The Monitor's own end is still tagged monitor/completed and dropped by mayStartSubagentFollowup, so the parent is not woken when the Monitor ends; the gate is unchanged.
Per-wake tracking of the absorbed marker, as CodeRabbit's second review suggested, was not added.
The Monitor-end gate applies to every provider and to pull-request watch notifications with a non-updated outcome on a delegated child thread; I verified only the Claude Monitor path in the real app.
The last Monitor line arrives in the same wake as the Monitor's end, so it is reported to the parent as part of that end wake.
A wake left behind a Monitor event and then absorbed by a user turn is itself tagged monitor/updated.

Failing repro for #36113: a per-line Monitor wake reaches the continuation
with no notification, so it is tagged background_task/updated and starts a
delegated follow-up that wakes the parent.

…s parent
Claude wakes a session for each Monitor line with a bare turn (init,
assistant, task-notification result) and no task_notification frame, so the
continuation carried no notification and fell back to background_task/updated,
which starts a delegated follow-up and wakes the parent.
The adapter now tags a wake turn that starts while a Monitor runs, with no
recorded task report and no due ScheduleWakeup, as monitor/updated. A
continuation carrying that tag replays only its own wake: a wake buffered
behind it gets a continuation of its own, so its answer keeps its own tag.
Fixes#36113
Co-Authored-By: Claude Fable 5.2 <[email protected]>
Macroscope's review found this PR approvable — Monitor progress is now distinguished from completed work so a delegated child’s monitor updates do not unnecessarily wake its parent. Scheduled and later buffered wakes retain separate handling, keeping the change narrowly scoped.
You can add or adjust custom eligibility rules. Learn more.
The Claude adapter distinguishes scheduled wakeups from Monitor-event wakes, tags Monitor-event continuations as monitor/updated, and separates later buffered wakes during replay. The orchestrator also changes follow-up eligibility for Monitor notifications.
Changes: Claude Monitor wake handling
Layer / File(s)
Summary
Classify scheduled and Monitor wakes apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts
The adapter tracks possible scheduled-wakeup starts and identifies Monitor-event wakes when a Monitor is running on the same native thread and the start is not attributed to a scheduled wake. Monitor-event continuations receive a monitor/updated notification.
Separate and re-offer buffered wakes apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts
The adapter can limit replay to the Monitor wake when later wake evidence is buffered, then offer the later wake. Tests cover later wakes that end with a result or are absorbed by a user turn.
Update follow-up eligibility and delivery test data apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/DelegatedCompletionDelivery.test.ts
The orchestrator permits follow-up work for Monitor notifications when their outcome is not updated. The delivery test uses source monitor for live delivery and command for checkpoint retries.
Monitor line wakes are tagged as Monitor updates so they no longer start delegated follow-ups, while a Monitor ending can still start one. No actionable merge-blocking risk remains. The PR description should be updated to say Monitor ends now start follow-up work.

The title names the actual change: a Claude Monitor line no longer wakes a delegated child's parent. The changeset tags Monitor-event wakes as monitor/updated and changes the Orchestrator gate for that outcome, which matches. The title also follows the conventional commit format in the template. The title is specific and concise, and it fits the bug fix described in the objectives.
Full details: Linked Issues check
Explanation
[#36113] The issue requires that per-line Claude Monitor wakes not start follow-up delegated tasks. The adapter change tags an eligible Monitor event wake as monitor/updated. On main, mayStartSubagentFollowup refuses any notification with source kind monitor (Orchestrator.ts, before the head change), so a monitor/updated wake no longer starts a follow-up. The adapter changes in ClaudeAdapterV2.ts implement the tag: bufferWakeMessage marks Monitor event starts, offerWakeContinuation offers monitor/updated when no wake report is recorded, and the drain split keeps a scheduled answer behind a Monitor continuation on its own default tag. The scheduled-wakeup margin exception keeps the issue's ScheduleWakeup concern covered. The adapter test report (409 passed) is the author's report and was not rerun here. Monitor-end behavior is not a requirement of this issue's per-line objective.
Full details: Out of Scope Changes check
Explanation
The head changes mayStartSubagentFollowup in Orchestrator.ts. The gate now allows any monitor notification whose outcome is not updated, so monitor/completed (the Monitor's own end) can start follow-up delegated work. The PR description states that the gate is unchanged and that Monitor ends remain dropped by mayStartSubagentFollowup. The pull request objectives also say Monitor-end handling is outside this change. The gate change is not needed for #36113: on main the gate already refuses monitor/updated, so the per-line tag fix alone removes the bug. The DelegatedCompletionDelivery.test.ts change exists to match the gate change: its live-delivery case now uses source monitor with outcome completed. Both changes alter Monitor-end behavior, which is the separate work of #31843 and #31856.
Resolution
Revert the mayStartSubagentFollowup change in apps/server/src/orchestration-v2/Orchestrator.ts so the gate matches main. Revert the matching test data change in apps/server/src/orchestration-v2/DelegatedCompletionDelivery.test.ts. Or, if Monitor-end follow-up behavior is intended, move it to a separate pull request linked to #31843 or #31856 and update the PR description to match.
Full details: Description check
Explanation
The description covers most template sections, but it has problems that block a pass. Problem: the author describes the reported bug as 'the parent was never woken with the child's final answer,' but the Problem section of the template is not stated as a clear problem with expected behavior and reproduction steps in the template's format. Change: the description says the gate change in commit 6847120 is needed, while the Scope section states that the gate change is outside the linked issue's scope, so the Scope and Change sections conflict. Scope: the author links #36113 but does not say why the gate change (which the PR itself calls a feature-adjacent overlap with open PR #31856) is a bug fix that belongs in this PR. Verification: the author gives detailed evidence, including commands and results, and states what was not checked, so this section is largely complete. Other problems: the description lists duplicate bullets (the Monitor-end caveat and the 'last Monitor line' caveat appear twice), it names several different model and commit identifiers inconsistently (commit 6847120 in the table versus 6847120 in the text), and the 'Who did the work' section names models that the template's agent note asks for in a different form. These gaps mean the description is not mostly complete with a clear scope.
Resolution
Split the PR. Keep the per-line Monitor wake fix (commits 2090a54, 6fc0f85, ff06982) in this PR. Move the Monitor-end gate change (commit 6847120) to a separate PR that links #31843 or #31856, or revert it, as the open out-of-scope check requests. 2. Rewrite the Problem section in one or two sentences. State the expected behavior and the observed behavior for the per-line wakes. 3. Rewrite the Scope section to link the issue that shows the bug and to say which part of the bug this PR fixes. 4. Use one commit identifier throughout. Correct the table entry (6847120) or the text entry (6847120) so both match. 5. Remove the duplicate caveat bullets in the 'Not in this change' section. 6. Keep the Verification section. Keep the statement of what was not checked (no web, desktop, or mobile screen recording).

When a Monitor continuation replayed only its own wake, it cleared the
thread's absorbed marker, which by then belonged to the later wake a user
turn had ended. That wake's continuation then never reached a terminal
event. The marker is now kept when the drained wake ended with its own
result, so the later wake consumes it on its own drain.

A root frame clears the absorbed marker, so when a Monitor continuation
leaves a later wake buffered the marker is always that later wake's. The
split drain now keeps it in every such case, and reads its own absorption
from its end frame alone.

The rework item said the problem still happens in the real app but not what was observed, so I ran the same flow myself: Claude Code 2.1.323, claude-haiku-5-5 parent and delegated child, fresh database from T3CODE_DEV_SEED=0 vp run dev, child arming a Monitor that prints EVENT_1..3 fifteen seconds apart. At ff06982, in 4 runs out of 4, the EVENT_1 and EVENT_2 wakes were tagged monitor/updated, started no delegated task and did not wake the parent; I also replayed raw recorded SDK frames through the adapter harness and got monitor/updated twice then monitor/completed. So I could not reproduce any per-line failure. What did still reproduce was the second half of the reported bug: the Monitor's end arrives as monitor/completed, Orchestrator.mayStartSubagentFollowup refused every monitor-kind notification, and the parent was never woken with the child's final answer. With per-line wakes now correctly tagged as monitor, a Monitor-using child went silent after its first result. This is my inference of what the verifier saw. New commit 6847120: mayStartSubagentFollowup now refuses only monitor notifications with outcome 'updated'; a Monitor that ends (completed, failed, cancelled) starts a delegated follow-up the way a background command's ending does. The parent-lock decision at dispatch uses the same predicate and follows. After the change, 2 real runs out of 2: parent woken once after STARTED and once when the Monitor ended, not for EVENT_1 or EVENT_2. Earlier commits are unchanged: 2090a54 tags a wake that starts while a Monitor runs (no task report, no due ScheduleWakeup) as monitor/updated and splits the drain so a later buffered wake keeps its own tag; 6fc0f85 and ff06982 keep the absorbed marker for a later wake left behind a split. Review state: all 35 checks passed on 6847120 and Macroscope approved it. CodeRabbit posted no rated code finding on 6847120, but its 'Out of Scope Changes' pre-merge check asks to revert the gate change or move it to a separate PR linked to #31843 or #31856. I did not revert it: without it the reported behaviour ('the parent should hear back when the child's work actually ends') does not hold in the real app. The objection is fair on scope: the gate change is the same one the open PR #31856 makes and will conflict with it; reverting 6847120 restores ff06982 exactly if the maintainers want the per-line fix alone. No new regex or parser.
Fixes #36113
Reproduction on main
Commit 9efd960 (origin/main). (1) I recorded raw Claude Agent SDK frames with the system Claude Code 2.1.323 (Haiku): a Monitor running
for i in 1 2 3; do sleep 4; echo EVENT_$i; done. Each per-line event woke the session with only system/init, an assistant message and result{origin:{kind:'task-notification'}} (no task_id). Only the Monitor's end sent a system task_notification ('Monitor "line monitor" stream ended'). (2) I ranT3CODE_DEV_SEED=0 vp run devon a fresh database, added a scratch git project, and usedt3 thread start --provider claudeAgent --model claude-haiku-5-5to start a parent that delegated one async task (delegate_task, Claude Haiku) telling the child to arm a Monitor printing three lines 15s apart, reply STARTED, then echo each event. Projection afterwards: the child's EVENT_1 and EVENT_2 wakes are user messages 'Background task completed.' with notification {source:{kind:'background_task'},outcome:'updated'}. Each started a new app_owned delegated task (3 subagent rows, all completed/delivered), and the parent got a 'Delegated task …' message and ran a turn for each. The Monitor's end came in as {source:{kind:'monitor'},outcome:'completed'}: no new delegated task, and the parent was not woken. (3) A failing adapter test on branch factory/repro-36113: a Monitor-event wake reaches continuationRequests with notification undefined, where monitor/updated is expected.Evidence
Run the same parent prompt against fresh real servers using Claude Code 2.1.323 / Haiku 5.5. Delegate a child that arms native Monitor with
for i in 1 2 3; do sleep 15; echo EVENT_$i; done, replies STARTED, echoes events, and reports MONITOR_DONE. Observe notification metadata and parent deliveries through stream end.These images show captured server projections in a transcript viewer, not web-client screenshots.

Caveats retained in the evidence: the head parent initially launched a stray native placeholder agent before making the requested delegation. The base child started an unintended second Monitor after the original stream ended; its later MONITOR_DONE delivery came from that extra Monitor. The original base stream's EVENT_3 was not delivered. Both runs delivered an initial STARTED acknowledgement; the demonstrated fix concerns subsequent Monitor progress and completion.

Tests
vp test run src/orchestration-v2/DelegatedCompletionDelivery.test.ts (apps/server): 60 passed; the 'live' row of 'delivers the run a background command's wake starts after the original result' now dispatches a monitor/completed notification and fails without the gate change ('expected undefined to not equal undefined' on run.delegatedTaskId), passes with it. vp run check:changed at 6847120: pass (format, lint, knip, graphql, typecheck of 3 packages, tests in 6 files). Real-provider runs on a fresh dev database: 4 of 4 at ff06982 with per-line wakes tagged monitor/updated and one parent wake; 2 of 2 at 6847120 with parent wakes only after STARTED and at the Monitor's end. A temporary harness test replaying recorded real frames gave monitor/updated, monitor/updated, monitor/completed; it was not committed. CI on 6847120: all 35 checks passed.
