The feed switches to a static league slate and keeps serving at full CBR
bitrate. No end marker, and no stall to detect, so neither of the obvious
exit conditions fires. The duration cap is the only stop condition.
Observed on a live match: 116 min recorded, still running 2h04m after
kickoff, stopped manually.

Verified end to end against a live match: 1080p H.264/AAC MPEG-TS at
~5.2 Mbit/s, recorded while the browser played the same stream.
Components:
- tampermonkey sniffer hooks fetch/XHR at document-start, captures the
manifest URL verbatim and POSTs it to the local catcher. v0.4 also traces
the API chain to find which call mints the token.
- catcher receives the URL and launches yt-dlp. Dedupes on the Kaltura asset
id and checks downloader liveness, so a mid-match page reload is both safe
and the recovery path for a dead downloader.
- creds stores secrets in the OS vault rather than a gitignored file, and
refuses to run on a backend that does not encrypt.
Protocol notes are in the README: the stream uses a two-stage token chain
(a ~25s hdnts token for the master playlist, a ~24h hdntl token for media),
concurrency is unrestricted, and the live window is ~30s with no DVR.
