The earlier #721 fix tolerated a ~10s "completed but no save_path"
window, but the real production stall sits upstream of that: SABnzbd
removes a finished download from the queue and runs par2 verify /
repair / unpack *in History*, exposing the live stage in the slot
`status` ('Verifying' / 'Repairing' / 'Extracting' / 'Moving' / ...)
with `storage` empty until the final move. `_parse_history_slot` mapped
EVERY non-'Failed' status to 'completed', so a still-extracting 1.7 GB
FLAC album looked "completed with no save_path" the instant download hit
100%. The poll burned its completed-no-path budget mid-PP and bailed,
freezing the UI on the last download emit (the stuck-at-99%/100%
signature). SAB then finished fine — which is why the job shows
Completed in History but SoulSync never staged it.
Root fix
- `_parse_history_slot` routes `status` through `_map_state`, so PP
stages stay NON-terminal: the poll keeps waiting (as 'downloading')
for as long as post-processing takes and only a real 'Completed'
flips to terminal success. `save_path` is trusted only on true
completion (mid-PP path fields may point at the incomplete dir).
Supporting / defensive
- `UsenetStatus.incomplete_path`: surfaced separately from save_path
(SAB `incomplete_path`) and used by the poll loops as a LAST RESORT
after the completed-no-path window, to recover the case where
`storage` never lands but the files are physically on disk.
- `poll_album_download`: dedicated, configurable completed-no-path
window (~120s via `download_source.album_bundle_completed_no_path_seconds`)
decoupled from the ~10s transient-miss window; incomplete_path
fallback; a 30s heartbeat log so the previously-silent poll loop is
diagnosable.
- `usenet.py` `_download_thread`: per-track parity — it was erroring
immediately on the first completed-no-path read.
- `album_bundle_dispatch.py` / `status.py` / `monitor.py`: use the
project `get_logger` so download-flow logs land in app.log under the
`soulsync.*` namespace (they were console-only before, which hid the
`[Album Bundle] flow failed` line during triage).
Tests
- PP-history state mapping; end-to-end Hunky Dory PP regression
(download -> Verifying/Extracting in History past both budgets ->
Completed+storage -> success); completed-no-path window +
incomplete_path fallback; per-track thread parity. ruff + compileall +
pytest all green (the only local failures are environmental: missing
tzdata + local tools/ffmpeg.exe, neither present on CI).
