"""Regression tests for auto-import live-progress visibility. Reported case: dropping an album into the staging folder, the import processes track-by-track but the UI shows nothing in the auto-import history list and the status indicator stays at "Watching" — no live progress visible. After a multi-minute processing window the row finally appears with status='completed', but for the duration of the import the user has no signal that anything is happening. Two pre-existing gaps caused this: 1. ``_record_result`` only fires AFTER ``_process_matches`` returns. For a 14-track album with ~30s/track post-processing, that's a 7-minute window with no DB row → nothing for the UI's ``/api/auto-import/results`` to return. 2. ``_current_status`` only ever transitioned between 'idle' and 'scanning' — never 'processing'. ``get_status()`` had no per- track index/name fields, so the UI had no way to render "Processing track 3/14: Mine". These tests pin both fixes: - An in-progress ``auto_import_history`` row gets inserted up-front and updated to the final status when processing completes. - ``get_status()`` exposes ``current_status='processing'`` plus per-track index / total / name during the per-track loop.
