"""Deep-research background-job executor.
|
||
|
||
Mirrors the roundtable executor's proven pattern:
|
||
|
||
- ``start_job(snapshot, job_id, lease_owner)`` — idempotent ``asyncio.create_task``
|
||
+ ``done_callback`` self-cleanup.
|
||
- ``_run()`` — sets user context, builds the :class:`AdapterBundle`, spawns a
|
||
heartbeat (lease renewal) + a cancel-watcher, then ``await engine.run()``.
|
||
- Cooperative cancellation via :class:`CancellationToken` — the runner checks it
|
||
at every phase boundary; the watcher sets it when ``cancel_requested`` appears
|
||
in the DB (cross-process cancel from another worker / API call).
|
||
|
||
Key difference from roundtable: deep research persists an **append-only event
|
||
log** (not whole-row polling) and persists **sources** incrementally via a
|
||
:class:`RecordingEventSink` that wraps :class:`PersistingEventSink`.
|
||
|
||
The executor writes terminal state (completed / failed / cancelled) to **both**
|
||
the job row and the session row so a single SSE stream + session GET carry the
|
||
full result without extra joins.
