basically fixes for when your disk gets filled up or sqlite errors so it doesn't put a thread in a unusable state

---

When event ingestion fails, T3 can mark a run failed while its provider keeps working. Follow-up messages then fail because the previous provider turn is still active.

Stop the affected provider turn and record its interruption atomically with the failed run after an ingestion failure. Before a continuation starts, recover a running turn left by an earlier failed run on the same provider thread and record its interruption. The existing native conversation is preserved. Web and mobile now label the ongoing setup script "Background setup".

Validation: vp run check:changed passed, including 75 focused tests and typechecks for the four affected packages. The continuation regression fails against current main with "The previous provider turn is still running."

Approvability

Verdict: Approved at 92cafce

Macroscope's review found this PR approvable — This PR addresses abandoned provider turns after ingestion failures, ensuring they are interrupted and recorded before a thread continues, while leaving normal execution unchanged. The remaining UI edits are labeling and accessibility improvements, and the recovery behavior has focused regression coverage.

📝 Walkthrough

Run execution now attempts to interrupt an active provider turn during eligible ingestion-failure recovery. Provider startup recovers abandoned turns before opening a session. Mobile and web background setup controls use a generic label and updated accessibility text.

Changes: Provider turn lifecycle

Layer / File(s)	Summary
Interrupt active turns after ingestion failures apps/server/src/orchestration-v2/RunExecutionService.ts, apps/server/src/orchestration-v2/RunExecutionService.test.ts	When ingestion fails and an active root provider turn is known, run execution attempts to interrupt it. Finalization can record the turn as interrupted. Tests cover interruption outcomes, terminal-write failures, lost ownership, and cases where no root turn is known.
Recover abandoned turns before session opening apps/server/src/orchestration-v2/ProviderTurnStartService.ts, apps/server/src/orchestration-v2/ProviderTurnStartService.test.ts	Startup identifies matching abandoned turns and interrupts the latest one before opening a provider session. Tests cover recovery conditions, cleanup failures, retries, and interruption of the current run during cleanup.

Background setup labels

Layer / File(s)	Summary
Update background setup control labels apps/mobile/src/features/threads/worktree-setup-card.tsx, apps/web/src/components/chat/TimelineWorkGroupRows.tsx	Mobile and web controls display “Background setup.” Their accessibility text identifies background setup and includes the setup script name.

Merge Risk: 🟡 Moderate · up to 92caf

A failure just after a provider turn starts can still leave it active and block a follow-up message. Close that gap before merging.

- Around line 600-615: The ingestion-failure flow in RunExecutionService must
repair the provider-turn projection by writing the interrupted
provider-turn.updated event after interrupting the provider, or explicitly treat
only the adapter’s inactive-turn result as successful recovery in
ProviderTurnStartService’s interruptTurn handling. Preserve failure propagation
for unrelated interrupt errors and ensure recovery does not settle or fail the
continuation before recording the repair.
