Coverage for little_loops / cli / backfill_worker.py: 0%

1"""Detached backfill worker spawned by the session_start hook (BUG-1882). 

2 

3Invoked as ``python -m little_loops.cli.backfill_worker <db_path> <path>``, 

4where *path* is either a single ``.jsonl`` transcript file or a project folder 

5whose ``*.jsonl`` files are globbed. Runs :func:`backfill_incremental` and 

6exits. Because it is spawned with ``start_new_session=True`` it outlives the 

7short-lived hook subprocess.
