A thread can finish its turn while subagents or background shells are still running. Restart continuation only resumed sessions that were still running with an active turn, so those threads stayed ready and the work disappeared. Startup now treats unterminated task rows like an interrupted turn. When continue-after-restart is on, the continuation prompt names the stopped tasks. Otherwise those tasks are settled as stopped and the thread gets the existing restart notice. A retry after those tasks were already settled restores the recorded names from the continuation marker. Malformed activity payloads are skipped, and plan or dream tasks stay excluded when a later status row omits taskType. Fixes pingdotgg#13400 Grok 4.7 via Cursor cloud agent.

When runtimePayload already contains SERVER_UPDATE_CONTINUATION_TASKS_KEY and openTasks is empty, this upsert preserves the stale task list while replacing the continuation marker. reconcileProviderSessions then reuses those tasks, emitting duplicate task stopped activities and adding them to the next continuation prompt. Clear the key when no tasks are open instead of conditionally omitting the write.

🟠 High src/serverRuntimeStartup.ts:852
An oversized persisted task label makes continuationPromptForTasks(stoppedTasks) exceed PROVIDER_SEND_TURN_MAX_INPUT_CHARS, so ProviderService.sendTurn rejects the restart continuation and the thread is marked errored instead of resumed. Limit or truncate task labels (and the resulting prompt) before calling sendTurn.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR substantially changes production startup recovery by discovering persisted background tasks, mutating task/session state, and initiating provider continuation turns for previously ready threads. Unresolved risks include duplicate task settlement from stale markers and restart prompts exceeding the provider input limit. Not approved because:

Bound the stopped-task continuation prompt.
listUnterminatedTasks accepts persisted task titles and details without a length limit. continuationPromptForTasks inserts up to 12 labels without truncation. A long label can exceed the 120,000-character ProviderSendTurnInput limit, so ProviderService.sendTurn rejects the restart continuation before it reaches the provider adapter.

Settle only open tasks, and run settlement once.
When openTasks is empty, stoppedTasks uses recordedTasks, which the code identifies as already settled. If sendTurn then fails, settleStoppedTasks runs again through settleAsError. Each call creates another thread.activity-appended event for the same activity ID. The activity row is upserted, but the upsert can overwrite its created_at.

In `@apps/server/src/serverRuntimeStartup.ts` around lines 674 - 725, Update
settleStoppedTasks to settle only openTasks and guard it so settlement runs at
most once. Keep stoppedTasks available for the continuation decision, but do not
settle recordedTasks when openTasks is empty or dispatch the same task
completion activity again.
After applying the fix, consider running `coderabbit review --agent` for local

What Changed
Restart continuation treats open background tasks the same as an interrupted turn.
markRunningProviderSessionsForContinuationandreconcileProviderSessionsnow notice unterminatedtask.*rows (the persisted form of ClaudeliveTaskIds). When "Continue threads after restarts" is on, the thread is continued with a prompt that names the stopped tasks. When it is off, or continuation fails, those tasks are settled as stopped and the thread gets the existing restart notice.This also covers the three restart-recovery cases that blocked the previous attempt:
startingsession restores recorded task names whenever the continuation marker is present, including aftersettleStoppedTaskshas already writtentask.completedrows. Promptless providers still receive the named tasks instead of{ continuation: true }.listUnterminatedTasksskips activity rows whosepayload_jsonis not valid JSON, so one malformed payload cannot abort continuation for every thread.taskTypeplanordream, even if a later status update omitstaskType.Why
A Claude thread whose turn has already finished can still be running subagents or background shells. The session is
readywith no active turn, so a restart neither continued it nor told the user the work was lost.Fixes #13400
