Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to Concurrent work for the same agent can create multiple active turns, allowing one completion to overwrite another result and leave the agent history inconsistent. Merge should wait until the lifecycle prevents a second turn from starting while one is already running. Sequence Diagram(s)sequenceDiagram

Greptile SummaryPersists every local-agent prompt and terminal result in SQLite while retaining the existing session-level status and latest-result view.
Confidence Score: 5/5The PR appears safe to merge, with no concrete blocking or independently actionable non-blocking defects identified. Turn creation and completion are transactionally coordinated with session state, existing databases receive an ordered migration, and restart reconciliation now consistently resolves both active sessions and their persisted turns.

| Filename | Overview |
|---|---|
| src/db/migrations.ts | Adds an ordered migration for durable, cascading local-agent turn records and supporting indexes. |
| src/local-agent-store.ts | Adds transactional turn lifecycle persistence, retrieval methods, row conversion, and restart reconciliation. |
| src/local-agent-manager.ts | Routes each agent execution through a persisted turn and finalizes that turn on every success and error path. |
| src/local-agent-store.test.ts | Covers completed and failed history, visibility across store handles, and use after legacy migration. |
| src/local-agent-manager.test.ts | Verifies manager-driven completion, continuation, failure, and restart reconciliation update turn history. |
| src/oauth-store.test.ts | Updates the expected migration ledger to include the new turn-history migration. |

before creating a turn, and reject the request when the agent status is already
running. Preserve existing behavior for other statuses, and add a regression
test covering two beginTurn calls for the same agent where the second call is
rejected.

Agent sessions need durable per-invocation history for coordination, but that history should remain an internal implementation detail. This adds a
local_agent_turnsmigration and store operations that begin and finish a prompt, response, or error atomically with the parent agent record.The manager now records start and continuation work through that lifecycle, and restart reconciliation closes any turn left running by a dead daemon. No turn ID, prompt, or prior output is added to the CLI presentation contract. Store, manager, migration, and restart behavior are covered by focused tests, and the full test suite passes.
