The recorder passed no -f, so yt-dlp used its default, which prefers video.
That was never a decision: on 2 Sep the master held exactly one rendition, so
there was nothing to choose between. If a master ever carries a video variant
the account is not entitled to, the default would take it and 403 on segments.
--prefer audio|video|best makes it explicit. best keeps the old behaviour.
Every run now logs the renditions the master advertises, parsed from
EXT-X-STREAM-INF, so we build evidence about whether video and audio ever
appear together instead of assuming entitlement shapes the master.
Observed so far, both audio nights: one rendition, mp4a.40.2 at 140 kbps.

record_live.py runs the whole chain alone: headless browser only to learn the
entry id (it appears at runtime; static HTML has none when nothing is live),
then plain Python mints a fresh master playlist, then ffmpeg records.
No password needed. Firefox session cookies run to late November, well past
any kickoff, so the job authenticates from the stored session.
Three failures found by testing against a live feed rather than at kickoff:
- yt-dlp's native HLS downloader fetches variant playlists with Python and
gets 403/404 on path-token URLs. Forced --downloader ffmpeg; this is
required, not a preference.
- ffmpeg 4.3.1 has no -reconnect_on_network_error. Removed here and in
catcher.py, which had the same unsupported flag.
- A master playlist outlives its stream: after a match ends the master is
still served while its variants 404. So a found master does not mean a live
stream, and a downloader that dies immediately means "not up yet" rather
than "failed". It now retries until the wait window expires.
Untested: the actual segment download for an audio-only stream, because
nothing is live right now. Video was verified working on 29 Aug.
