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.

ApprovabilityVerdict: 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. Not approved because:

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.

Note Grok responding on behalf of Julius. 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 #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 |
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.
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 stayedrunning. Sixteen Stop presses each ranprovider-turn.interruptto success, and the run still didn't move. A steer 10 minutes after the result failed withClaude provider turn … is not the active turn. That error shows the adapter had already cleared its active turn, which onlyfinalizeActiveTurndoes. 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
interruptTurntakes its "Stop after the turn settled" branch and returns without emitting a terminal. The interrupt effect succeeds,thread.background-work.settlebails because a run is stillrunning, and nothing ever ends the run.Change
interruptTurnmay 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 frominterruptTurnbefore its terminal arrives.ProviderTurnControlService.interruptonly acts when the adapter reportsturn_not_activeand the projection still shows the turnrunning.interruptAndAwaitTerminal, which both now share.RunExecutionServicewrites for an interrupted terminal. Those writes now come from one sharedmakeFinalRunWrite, extracted fromwriteFinalRunEvents:run_interrupt_resultitem, run, root node and provider thread, marked as ended;checkpoint.captureeffect;ProviderEventIngestor.normalize. That also cancels the turn's unanswered native user input, using the existing guard that protects answers.writeIfRunCurrent, which now accepts several expected statuses and enqueues effects in the same transaction. It commits only while the run is stillrunningon the stopped turn's attempt. Ingestion's own final write (finalizeRootRun) now uses the same guard (starting/runningon its attempt) instead of checkingshouldFinalizeRunand 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 staysrunning". 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 reportsturn_not_active.interrupted.
