What Changed

A Claude task notification that arrives after the parent turn has settled now keeps the thread's background liveness as working until the follow-up turn starts. The completion sound, toast, and desktop notification share sidebar status, so none of them fire in that gap.

A completion that does not resume the provider still clears liveness and alerts once. Approvals, questions, and failures still alert immediately.

Why

When a subagent or monitor finished, background liveness cleared before the agent resumed. The thread read as ready with the waiting turn's completedAt, and the shared completion trigger treated that gap as a finished run. The alert fired, then fired again when the follow-up turn actually settled.

The handoff is the task notification with no turn open, and the resume is the next turn.started. Holding liveness across those two events keeps the shell off ready for the whole gap, including while the model is starting the follow-up.

Fixes #13625

Verification

From apps/server at commit da8bc41c3822:

vp test run src/orchestration/Layers/ProviderRuntimeIngestion.test.ts src/orchestration/ThreadBackgroundLiveness.test.ts src/provider/Layers/ClaudeAdapter.test.ts

Result: 3 files passed, 249 tests passed (6.59s). Regression coverage is the ingestion tests that keep background liveness through a provider resume until the follow-up turn starts, clear it when a completion will not resume, and drop the hold when the session errors, plus the liveness tests that hold working after a waking completion until the provider resumes.

vp run typecheck

Result: tsc --noEmit exited 0 (cache disabled).

From apps/web at commit da8bc41c3822:

vp test run --project unit src/components/Sidebar.logic.test.ts src/components/ThreadNotificationCoordinator.test.tsx

Result: 2 files passed, 189 tests passed (1.27s). Regression coverage is the sidebar test that keeps a ready session working while background liveness is held, and the notification tests that alert a failure or approval immediately while background work is live, alert once when background work ends without a resume, and alert the follow-up once when background work hands off to a running turn.

vp run typecheck

Result: tsc --noEmit exited 0 (cache disabled).

From packages/contracts at commit da8bc41c3822:

vp run typecheck

Result: tsc --noEmit exited 0 (cache disabled).

Limitations: Checked on Linux only. The waking-task handoff is covered by these unit tests; a live Claude session and real desktop notification playback were not exercised.

Summary by CodeRabbit

  • Bug Fixes
    • Background work now remains visible as active while a task is handing off to a follow-up turn, and clears when the turn begins or the session ends. Ordinary task completions do not keep background work active.
    • Completion notifications are better timed during background work: handoffs no longer trigger a premature completion alert, while failures and approval requests remain noticeable. A completion alert appears when monitoring ends without another turn, and later completions are still reported.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR changes production liveness and completion-alert behavior across the Claude adapter and orchestration lifecycle. Unresolved findings identify missing release/expiry paths and a lost handoff hold, creating risk of threads remaining stuck as working or emitting incorrect settlement behavior.

📝 Walkthrough

Walkthrough

Task completions can now indicate that the provider will resume. Server orchestration holds background liveness through that handoff and clears it when a follow-up turn starts or a clearing event occurs. Tests cover provider signaling, liveness transitions, and web notification behavior.

Changes

Provider Resume Handoff

Layer / File(s) Summary
Mark provider-resuming task completions
packages/contracts/src/providerRuntime.ts, apps/server/src/provider/Layers/ClaudeAdapter.ts, apps/server/src/provider/Layers/ClaudeAdapter.test.ts
TaskCompletedPayload adds the optional resumesProvider flag. The Claude adapter sets it for task notifications received without an active turn. Tests cover notifications on both sides of a turn boundary.
Hold liveness through the provider handoff
apps/server/src/orchestration/ThreadBackgroundLiveness.ts, apps/server/src/orchestration/Layers/ProviderRuntimeIngestion.ts, apps/server/src/orchestration/ThreadBackgroundLiveness.test.ts, apps/server/src/orchestration/Layers/ProviderRuntimeIngestion.test.ts
The liveness service can hold "working" after a task completes while awaiting provider resume. Runtime ingestion sets the hold for flagged completions and releases it on accepted turn starts or aborts, and on session errors or stops. Tests cover release and clearing behavior.
Cover notification behavior during handoff
apps/web/src/components/Sidebar.logic.test.ts, apps/web/src/components/ThreadNotificationCoordinator.test.tsx
Tests cover status resolution from background liveness and notification behavior during live work, monitoring completion, and handoff to a running turn.

Merge Risk: 🟡 Moderate · up to da8bc

Completion alerts can be lost indefinitely or fire before the provider resumes. Resolve both liveness paths before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to da8bc

A task completion can leave a thread appearing busy and suppress its completion alert if no follow-up turn or session-ending event arrives. The identified effect is limited to the affected thread; approvals and reported failures retain separate alert paths.

Retained concerns

  • Medium · reliability · inferred: A notification after the parent turn settles arms a thread-level working hold based on the absence of an open turn, not confirmation that another turn will start. If the session remains ready without a follow-up or terminal event, the hold has no release path or expiry in the inspected service; the thread can remain working and its completion alert can remain suppressed.
Security review details

Security Blast Radius

  • inferred — The demonstrated effect is on the liveness and completion notification of the thread identified by the provider event. The inspected change does not establish broader tenant, credential, or infrastructure exposure.

Trust Boundaries and Controls

  • observed — Ingestion consumes the provider event's thread identity and explicit resume flag. The inspected consumer does not independently authorize that flag; upstream provider-event ownership checks were not established, so this is not a verified cross-thread attack path.

Resilience and Maintainability Implications

  • observed — Explicit stop, error, exit, and accepted turn transitions clean up a hold, and the set prevents simultaneous duplicate holds. The inspected paths do not establish delivery ordering or prevent a later repeated completion from arming another hold.

Hardening Proposals

  • proposed — Bound the resume hold to a confirmed handoff or recovery deadline, and associate it with a task or turn generation so a late repeated completion cannot re-arm a released handoff.

Release a resume hold when the provider does not start a follow-up turn.

ClaudeAdapter marks a task_notification as resumesProvider: true when no turn is open. Ingestion then keeps the thread working. If the provider emits no follow-up turn.started, turn.aborted, error, stopped, or exit event, the hold remains indefinitely. A ready-state event does not release it. The sidebar can remain "working" and suppress the settled-run alert.

Add a release event for a result that arrives without an active turn, or add a bounded timeout for the hold.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Preserve the pending resume while other tasks remain live.

If a waking task completes while a monitor remains live, this condition discards the resume hold. If the monitor then ends through an unflagged task.updated terminal status before the follow-up turn starts, getThreadBackgroundLiveness returns null and can trigger a premature completion alert. Record the pending resume even while other tasks are live. Apply the hold when the last task leaves.

Bound the provider-resume hold.

ClaudeAdapter marks a task_notification as resuming the provider when no turn is active. If the SDK query remains open without a follow-up lifecycle event, the hold has no expiry, so the thread can remain "working" and suppress completion alerts indefinitely. Add a bounded fallback that clears the hold and permits one completion alert.

Review comment at @apps/server/src/orchestration/ThreadBackgroundLiveness.ts
around lines 150 - 151:
Add a bounded expiry for the provider-resume hold added to resumeHolds when
stillLive is false; when it expires, clear the hold and allow one completion
alert, while preserving the existing hold behavior before expiry.

The docstring check on this diff stayed at 50%. The new tests were
anonymous callbacks, so they did not count. Name those helpers, with
JSDoc, and keep the resume-hold helper as a documented function. The
handoff behavior is unchanged.
