A completed Claude subagent could appear running again when an old buffered task_started replayed. Stop could then leave the card running because Claude did not send another terminal notification.

Discard superseded buffered starts and apply each native outcome once, preserving genuine resumes. Stop returns a confirmed native outcome directly; when the adapter already knows the task finished, the effect repairs its stale projection through persisted subagent, node, and turn-item events. Unconfirmed requests and timeouts never imply cancellation.

Consolidated regression fixtures and removed compatibility handling for an intermediate, unmerged command shape. The short confirmation wait remains necessary when the old run's event subscription has closed.

Validation: 312 tests passed across ClaudeAdapterV2, ThreadStop, EffectWorker, ProviderTurnControlService, and orchestrationV2 contracts. Server and contracts typechecks passed. Targeted lint passed with two existing unused-variable warnings; formatting passed. Tests cover stale starts and outcomes, genuine resumes, native-only confirmation, siblings, and persisted events for cached clients.

Fixes #17847

Implemented with GPT 6.1 Sol through the Codex harness.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR changes Claude subagent lifecycle handling across the adapter, effect worker, orchestration commands, provider contracts, and persisted projections. Although the intent and regression coverage are clear, the asynchronous confirmation and replay behavior has a broad production blast radius and warrants human review.

📝 Walkthrough

Walkthrough

Native subagent stops now wait for provider-confirmed terminal outcomes. Confirmed outcomes carry status, completion time, and result through targeted settlement. The orchestrator applies eligible updates to subagent and child-work projections.

The Linked Issues advisory asks for additional automatic cleanup when an owning session disappears without a Stop request. This PR is scoped to the diagnosed stale buffered start and the Stop fallback, so I am leaving that broader recovery behavior out of this diff. Stopped task notifications already use the normal terminal path in ClaudeAdapterV2: task_notification with status: stopped maps to cancelled, and the buffered-start purge applies to that notification too. Existing adapter tests cover stopped notifications and idle-pin release, while the added Stop tests cover missing sessions, no-op/error outcomes, durable cancellation events, siblings, and later resumes. Both actionable review threads are resolved; no additional code change is needed for this advisory.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Complete a Stop waiter only for a native outcome.

If a workflow's parent turn fails while stopSubagent waits, finalizeActiveTurn calls updateClaudeSubagentNode with a terminal status without receiving a task_notification. This code completes the Stop waiter anyway. stopSubagent can then return that locally assigned status as a confirmed provider outcome. Signal the waiter only when a native terminal outcome caused the update.

@coderabbitai Addressed the outside-diff finding in review 5496832387 with b2db626743. The registry now records confirmed outcomes only when a native task_notification updates the task, clears that evidence on resume, and completes Stop waiters only for those outcomes. Both the in-flight waiter and a subsequent Stop no longer interpret parent-turn cleanup as provider confirmation.

Added regression cases for parent API failure and interrupted streaming while Stop waits, plus a subsequent Stop on the locally terminal task. Both cases fail against 9f80bfd and pass after the fix. All 243 Claude adapter tests passed; server typecheck and formatting passed; targeted lint passed with one existing unused-variable warning.

@Yash-Singh1 Thanks for the fix. I inspected b2db626743; it addresses the outside-diff finding.

  • Stop waiters complete only when confirmedOutcome contains a native outcome.
  • A subsequent Stop reads the same evidence, not the terminal status assigned by parent-turn cleanup.
  • Resume clears that evidence.
  • The regression cases check that both in-flight and subsequent Stop requests fail without confirmation after parent API failure or interrupted streaming.

I did not rerun the reported tests or checks. No further change is needed for this finding.

Learning: In apps/server/src/orchestration-v2/Orchestrator.ts, only dispatchSubagentStop adds the targeted subagent payload to provider-turn.interrupt; full-turn interrupts from thread.stop do not enter the targeted background-work settlement branch. In apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, Claude native subagents are registered as running with a non-null startedAt. Repeated task_started events preserve startedAt for running tasks; reopening a terminal task assigns a new startedAt. Evaluate the targeted settlement timestamp guard against these lifecycle rules, not a hypothetical pending native-task start path.

@coderabbitai review

Please review current head 69a9a9c8d9. The earlier request for b2db626743 was not completed because the head changed. This final correction preserves native outcome evidence across same-generation Agent tool_result updates, clears it on genuine resumes, and still completes Stop waiters only for native notifications. The new regression fails before the fix; all 244 adapter tests and all eight required CI checks pass on this head. All inline findings have been addressed and resolved.

🟡 Minor · Keep the stop outcome entry while another Stop call is waiting. · ClaudeAdapterV2.ts:9114-9148

apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts:9114-9148
🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Keep the stop outcome entry while another Stop call is waiting.

Two concurrent stopSubagent calls can share the same deferred. If the first call times out, its Effect.ensuring block deletes the map entry while the second call still waits on that deferred. A later native task_notification then finds no entry at ClaudeAdapterV2.ts:5268, so it cannot complete the second waiter. The second call times out with Claude subagent Stop was not confirmed by a native outcome.

Track the number of active waiters and delete the outcome only when the last waiter finishes.

The concurrent Stop waiter concern in the latest review does not apply to the current production path, so I am leaving the code unchanged.

ProviderTurnControlService is the only production caller of stopSubagent, and its interrupt path is called by EffectWorker. EffectOutbox.claimableCandidatePredicate serializes lifecycle effects within each thread: a running effect or an earlier pending effect blocks the next claim in that lane. Title generation has a separate lane; targeted interrupts do not. The adapter also checks that the task belongs to the caller's app thread, so another thread cannot concurrently stop that task. A timeout settles the first call before the next Stop effect can execute.

I verified the source and ran the existing FoundationPersistence tests for per-thread effect serialization and for not reclaiming a live effect after lease expiry. Both pass. Adding waiter counters for unsupported concurrent direct adapter calls would expand this fix without addressing a reachable user failure. No additional production changes are needed for this finding.

Merges upstream `pingdotgg/t3code` `5070a83a32` (48 commits, base
`e688034b5f`) into the fork. It does not stack on another PR.

## Merge
- 240 of 240 upstream-range files landed. Fork delta: 775 files.
- One conflict: `apps/web/src/routeTree.gen.ts`, regenerated for
upstream's new `/_chat/new` route. The other 18 files both sides touched
auto-merged: `duplicate-adds` and `resolution-check` are clean, and
every delta guard holds.
- `pnpm-lock.yaml` was re-derived by install, and `verify --only
lockfile` passes.
- Sweep: `promptLinks/HostedPromptLinkLanding.tsx` renders only in the
`hosted-static` auth state, which Moatless never reaches. Taken as
upstream's.
- Unsupported methods: ADD 0, DROP 0.

## Verification
`verify.mjs` passes duplicate-adds, tripwires, resolution-check,
unsupported-methods, lockfile, fmt, lint, typecheck and build. `test`
fails only on files that fail alone and failed the same way on the last
three merges, because of the sandbox: shared `AgentScope`
(`oom_score_adj` is 935 here), server `ServerBrowserPage` (no Playwright
browser), `AcpAdapterV2`, `OrchestratorReplayFixtures`, and
provider-opencode `OpenCodeServerLedger`.

## Usable as-is
- Prompt links (pingdotgg#18454): `/new?prompt=…`, `ThreadLinkPrompt` on thread
routes, and copy-prompt-link from messages and the command palette.
Choosing a project and placing the prompt work against Moatless.
- Terminal colors (pingdotgg#17168), context meter rounding (pingdotgg#17539), stable
button text (pingdotgg#18866), setup wizards follow themes (pingdotgg#18725), Git actions
follow the selected thread (pingdotgg#18862), dropped threads attach to pending
answers (pingdotgg#18789), the compact merge-button second click (pingdotgg#18878), a
numeric `q` on pull requests (pingdotgg#18666), the home-page bounce fix
(pingdotgg#18672), running terminals shown in the sidebar (pingdotgg#18740), and
computer-use titles (pingdotgg#18865).
- Mobile and desktop fixes (theme contrast, settings rows, the PR action
bar, image caching, the iOS 27.2 black screen, Hyprland, updater
diagnostics).
- "Update everything" sidebar pill (pingdotgg#18053): inert against Moatless,
which advertises no `serverSelfUpdate` or `versionAdvisory`.

## Unsupported in Moatless / needs implementation
- Prompt-link "clone this repository"
(`NewThreadLinkView.cloneRepository`): needs `projectClone.start` and
the `projectCloneTracking` capability. It refuses with a message today.
Added to gaps.md under *Project and repository management*.
- Renaming built-in models (pingdotgg#18840): saves through
`server.updateSettings` (custom model entry with a built-in slug). It
stays behind `FEATURES.providerConfiguration`, under the existing
settings gap.
- Provider secret settings (pingdotgg#18505, `secretSetting` and
`isSecretSetting` in contracts): stored on the host, so they fall under
the same settings gap.

## Backend behavior to consider reproducing in Moatless
Recorded in gaps.md under *Runtime fixes upstream made to its own
server*:
- A confirmed Claude subagent outcome settles that task and its child
work (pingdotgg#18778, the new `subagent` target on
`thread.background-work.settle`).
- Claude thinking before a tool call stays a collapsed Thought (pingdotgg#18887).
- Codex title and branch-name generation no longer starts the user's MCP
servers (pingdotgg#17058).
- The event store resyncs a thread holding an event type from a newer
build (pingdotgg#15937, `isKnownOrchestrationV2EventType`).
- A migration id clash stops startup with a clear error (pingdotgg#15925).
- Cached branch PR lookups start no git process (pingdotgg#17063).
- PR head commits are reported for Forgejo, GitLab and Bitbucket
(pingdotgg#18463, pingdotgg#18608, pingdotgg#18402), and PR bases resolve to branch names (pingdotgg#18754).

Move Claude MCP registration to the SDK control channel, inherit nested
Claude effort accurately, and isolate Linux agents in systemd scopes with
OOM protection. Add a capability-gated native Claude task Stop control and
MCP operation that preserve the owner turn and await the actual outcome.

Adapt upstream pingdotgg#17898 (f82796a), pingdotgg#17662 (a0a601c), pingdotgg#17496
(98beed1), pingdotgg#17826 (8c777fb), and pingdotgg#18778 (265fb70) to the stable
provider services and protocol 1. Keep custom forks, durable workers,
account switching, and the installed phone protocol. Package as custom.10.

Validation: focused provider, worker, recovery, connection, authorization,
and isolation suites; server/web typechecks; targeted lint (existing
warnings); web/native builds; isolated conversation-snapshot startup;
real Linux scope/oom-score launch. No browser or Android device test.

[Bug]: "Waiting on subagent" chip never clears after the SDK reports the subagent stopped, and Stop does nothing
