 ## Verified behaviours worth remembering
 - **Never scp generated configs** (`mediamtx.yml`, `copyparty.conf`, `Caddyfile`, `dump-users.txt`, `.env`): a template copy wiped all streamers once. They are gitignored now; `*.example.*` are reference only.
 - Caddy runs in a container: anything it serves from disk must be a mount (`/srv/live` was missing → 404).
+- MediaMTX stamps recording filenames in its container clock: without `TZ` it is UTC and the plugin reads names as Eastern (4 h off). `TZ=America/New_York` is set on the container.
 - MediaMTX 1.21 refuses to start without `webrtcAdditionalHosts` or `webrtcIPsFromInterfaces`; configure.py writes the public host in.
 - Jellyfin honours provider-supplied season numbers on a Shows library (day seasons appeared). Next check: Monday 04:10 ET should fold them into a week season.
 - A stream indexed by Jellyfin while still recording has no duration and skips to the next episode on seek — fixed by recording into `.live/` so nothing sees a file until it is finished and flat.
