Problem

Stop does nothing on a run whose provider turn its adapter has already settled, if the run never projected that turn's end. The thread shows "Thinking" until the app restarts, and a follow-up sent meanwhile is routed as a steer and fails.

In #15197, the Claude CLI reported result / success, but the run, attempt and provider turn stayed running. Sixteen Stop presses each ran provider-turn.interrupt to success, and the run still didn't move. A steer 10 minutes after the result failed with Claude provider turn … is not the active turn. That error shows the adapter had already cleared its active turn, which only finalizeActiveTurn does. So the adapter finished the turn, and its terminal never reached the projection.

Stop can't recover from that. With no active turn, Claude's interruptTurn takes its "Stop after the turn settled" branch and returns without emitting a terminal. The interrupt effect succeeds, thread.background-work.settle bails because a run is still running, and nothing ever ends the run.

Change

  1. The adapter says when it had nothing to stop. interruptTurn may now return "turn_not_active". That means the adapter holds no live turn with that id and emits nothing for it, so whatever terminal it will ever emit for that turn already went out. Claude returns it from its settled-turn Stop branch. Every other adapter keeps returning nothing, so it keeps today's behavior. A time-based guess isn't safe: OpenCode2, for example, can return from interruptTurn before its terminal arrives.
  2. Stop ends an orphaned run the way ingestion would. ProviderTurnControlService.interrupt only acts when the adapter reports turn_not_active and the projection still shows the turn running.
    • It first waits for the turn's end to project, since an already-emitted terminal may still be in flight. It uses the same bounded wait as interruptAndAwaitTerminal, which both now share.
    • If the end never projects, it ends the run with what RunExecutionService writes for an interrupted terminal. Those writes now come from one shared makeFinalRunWrite, extracted from writeFinalRunEvents:
      • the attempt, run_interrupt_result item, run, root node and provider thread, marked as ended;
      • the checkpoint.capture effect;
      • the cascade over provider-native subagents, rebuilt from the projection, including linked child threads. App-owned subagents run on their own runs and sessions, so they're left alone.
    • The provider-turn update goes through ProviderEventIngestor.normalize. That also cancels the turn's unanswered native user input, using the existing guard that protects answers.
  3. Both run-ending writes are atomic and exclusive. The orphan path commits everything in one writeIfRunCurrent, which now accepts several expected statuses and enqueues effects in the same transaction. It commits only while the run is still running on the stopped turn's attempt. Ingestion's own final write (finalizeRootRun) now uses the same guard (starting/running on its attempt) instead of checking shouldFinalizeRun and then writing without a guard. Whichever commits first wins, and the other writes nothing. The settle command then runs unchanged, because the run has already ended.

This PR doesn't find why the terminal was lost in #15197. The server trace for that window had rotated out, so the root cause is still open. This fix makes Stop a reliable way out of that state.

Scope and approval

This fixes the Stop half of #15197, which a maintainer triaged here: #15197 (comment). The triage names this gap: "If the in-memory active turn is already gone, it returns success without emitting turn.terminal, so the outbox row can succeed while the run stays running". The diagnosis is in #15197 (comment).

Verification

  • ProviderTurnControlService.test.ts, ends the run of a stopped turn its adapter settled unseen (real SQLite stores, event sink and ingestor). It seeds a running run with a provider-native subagent, an app-owned subagent and a pending native user-input request, then runs Stop against an adapter that reports turn_not_active.
    • Run, attempt, provider turn, root node, and the native subagent and its node end interrupted. The app-owned subagent and its task node stay running, the request is cancelled, a run_interrupt_result item appears, and checkpoint.capture is enqueued.
    • A late starting/running-guarded terminal write is rejected and changes nothing.
    • With the run-ending call disabled, this test fails.
  • ProviderTurnControlService.test.ts, waits for a settled turn's end only when its adapter no longer holds it.
    • With turn_not_active, Stop stops waiting on the read where the turn's end lands.
    • An adapter that reports nothing isn't waited on.
  • ClaudeAdapterV2.test.ts. The two settled-turn Stop tests now assert that interruptTurn returns turn_not_active and emits no second terminal.
  • Wider runs. vp test run on 16 focused files: ProviderTurnControlService, ProjectionControlReads, Orchestrator.control-reads, EffectWorker, SteeringCompletion.integration, RunExecutionService, RunFinalizationService, FoundationPersistence, SubagentProjection, DelegatedCompletionDelivery, ThreadManagementService, runtimeLayer, ProjectionSettlement, and the Claude, Codex and OpenCode2 adapters. 544 tests pass. The 16 replay-harness test files, whose wiring changed, pass 428 tests.
  • Typecheck and lint. tsc --noEmit is clean for apps/server. vp lint on the changed files reports only a warning that is already on main (unused layer).

Not checked: I couldn't reproduce the original lost terminal, so I haven't run Stop against a real stuck Claude run. Adapters other than Claude keep today's Stop behavior until they report turn_not_active. A late root provider_turn.updated from ingestion is still written without a guard, as it is for superseded attempts, so a turn that really did finish could show completed under a run that Stop ended as interrupted.

Model: Claude Opus 5.5 (1M context). Harness: Claude Code in T3 Code.

🤖 Generated with Claude Code

When a provider adapter has already settled a turn but the run never
projected that turn's end, Stop did nothing: the adapter's interrupt
returns without a terminal for a turn it no longer tracks, so the run,
attempt and provider turn stayed running and the thread looked busy
until a restart.

The Stop interrupt now waits for a running turn's terminal to project,
as restart already does. The settle follow-up then ends the stopped run
as interrupted if its live attempt's turn is still running, since no
terminal will ever arrive for it.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a substantial production recovery workflow that finalizes orphaned runs, cascades subagents, and enqueues checkpoint effects through new atomic persistence behavior. An unresolved high-severity Codex path may bypass the recovery, while the polling loop also raises a concrete database-load concern.

📝 Walkthrough

Walkthrough

Provider-turn control now waits for terminal projections after an adapter reports an inactive turn. If the turn remains unterminalized, it can finalize the eligible run as interrupted. Finalization writes events and effects conditionally, with tests covering state updates and rejected late writes.

Changes

Orphaned turn finalization

apps/server/src/orchestration-v2/ProviderAdapter.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts
The interrupt contract can report turn_not_active. ClaudeAdapterV2 returns this outcome in its runtime-restart path, and settled-turn tests check the outcome.

Merge Risk: 🔵 Low · up to c9076

Stop can now end runs whose provider turn settled without a recorded terminal event. When that happens, each Stop may run up to 1,000 back-to-back database reads before the run is ended, which adds bounded load if many Stops occur at once. This is a minor follow-up and does not block merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to c9076

This changes how stopped work is finalized. Ownership checks and atomic updates limit the risk of ending the wrong work or conflicting with normal completion, but some failure and recovery cases remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • observed — The inspected recovery write affects the selected run and attempt, root node, provider turn and thread, pending native input, checkpoint work, and qualifying provider-native subagents including linked child-thread state. App-owned subagents are excluded from the root-run cascade.

Trust Boundaries and Controls

  • observed — The changed EventSink interface is backed by an internal dependency-injected service, not itself an HTTP or RPC handler. The inspected Stop caller validates provider-session, thread, and turn relationships, then supplies projection-derived run and attempt identities to an in-transaction ownership guard. Complete network-route coverage remains unavailable.

Resilience and Maintainability Implications

  • observed — Recovery depends on obtaining a provider session and an explicit inactive-turn outcome; the no-session branch returns without invoking orphan finalization. Separately, provider-turn snapshots can use unguarded ingestion and replace projected turn status. These bound the demonstrated recovery guarantees; neither was established as a PR-introduced security regression.

Bound ordinary Stop polling by elapsed time and pace the reads.

If the provider turn and attempt remain projected as running, ordinary interrupt can perform 1,000 getProviderControlContext calls. Each call opens a transaction and performs multiple projection queries. yieldToRuntime yields to the event loop but does not add a polling interval. Concurrent Stop effects can therefore multiply this bounded but material database load. Use an elapsed-time deadline and a short Node-timer interval between polls.

…tion would

Addresses review of the Stop fallback:

- A timed-out wait did not prove the adapter had settled the turn: an
  adapter such as OpenCode2 can return from interruptTurn before its
  terminal arrives. interruptTurn may now report "turn_not_active" (the
  adapter holds no live turn with that id and emits nothing for it).
  Claude reports it from its settled-turn Stop branch; other adapters
  keep reporting nothing and never trigger the fallback. Stop waits for
  the turn's end to project only on that report, and the settle command
  ends the run only when the interrupt says the turn is orphaned.
- The fallback now writes exactly what run execution writes for an
  interrupted terminal, through a shared makeFinalRunWrite: the
  checkpoint capture effect and the run-owned subagent cascade, rebuilt
  from the projection, along with the attempt, interrupt result, run,
  root node and provider thread.
- ProviderTurnControlService tests cover an orphaned turn, a terminal
  landing during the wait, and an adapter that reports nothing.

Addresses the second review round:

- Stop and a late terminal could each undo the other: ingestion checked
  shouldFinalizeRun and wrote unguarded, and the settle command's read
  and commit were separate. ProviderTurnControlService now ends an
  orphaned run itself with one writeIfRunCurrent (extended to take
  expected statuses and effects), committed only while the run still
  runs the stopped turn's attempt. Ingestion's final write takes the
  same atomic guard, so whichever commits first wins. The orchestrator,
  effect worker and contract changes are reverted: the run has ended
  before the settle command runs.
- The subagent cascade rebuilt from the projection now covers only
  provider-native subagents. App-owned ones run on their own runs and
  sessions, and the run's ingestion never tracked them.
- The provider-turn update is normalized through ProviderEventIngestor,
  which also cancels the turn's unanswered native user input, written
  with the existing guard against overwriting answers.
- A real-SQLite test covers the orphaned run end to end, including an
  app-owned subagent left alone, the native input cancelled, the
  checkpoint capture enqueued, and a late terminal rejected.

…cascade

An app-owned delegated task has a parent-thread subagent node with the
parent run's id and its subagent's id. The projection-rebuilt cascade
filtered out its subagent row and turn item but still matched that node,
so Stop on an orphaned parent marked it interrupted while the task kept
running. Nodes whose id is an app-owned subagent's are now excluded, and
the orphaned-stop test seeds both kinds of node.

Thanks for digging into this one, @Info-Cado. Your write-up of the #15197 case is what pinned down why Stop couldn't get out of it.

#15442 just merged and covers the same escape. When Stop runs on a run that's still marked running but has no terminal left to ingest (the interrupt returns without emitting one, or the session or native turn is already gone), the Stop follow-up now ends the run itself. It marks the attempt, run, and provider turn interrupted, closes streaming output and pending requests, cascades provider-native subagents, and enqueues the checkpoint capture. It also guards against overwriting a newer attempt. Its tests include the "interrupt returned, no terminal" case your PR targets, so I'm closing this as superseded.

#15197 stays open for the root cause, where the Claude terminal never reaches the projection in the first place. If you can still reproduce Stop leaving a run stuck on current main, please reopen or comment here with the trace.

Closing a session with a live turn left the run unsettled: three of the
four adapters emitted nothing at all, and Pi had no code path that emits
turn.terminal during teardown. This is the adapter-side closure of the
gap named in pingdotgg#15197, where a provider "returns success without emitting
turn.terminal". pingdotgg#15298 owns the Stop half; this does not depend on it —
RunExecutionService already guards on rootRunFinalized, so a late
terminal cannot settle a run twice.

OpenCodeAdapterV2's message-cache deletion is deliberately NOT here; it
belongs to the reclamation branch and would otherwise collide.
