Playback failed in Jellyfin the day after deployment, for uncached videos only. The handler blocked on the full download-and-mux before sending anything at all -- not even response headers -- so a 46-minute upload sat silent for 79 seconds and the client gave up. The proxy counted it a success, which is why /healthz and doctor both looked fine. Yesterday's "DirectPlay verified" only ever ran against videos already pulled during testing, so the first-play path was never exercised. The output is already a fragmented MP4, so it is readable while being written; a finished file only buys a correct duration and working seeks. Cap the wait at --first-byte-grace (12s, explicit in the unit) and stream whatever has not muxed by then. Measured: 156s -> 12.0s TTFB on a 66-minute upload, with ranges on a complete file unchanged. The cost is a first play with no seek bar when the grace is missed. Every later play of that video is perfect. Also fixes a hang found while testing this: the streaming loop waited on "finished and good" rather than "finished", so a producer that died after writing some bytes held the connection for the full 45s stall timeout and then dropped it. The stale yt-dlp warning pointed at youtube-automate's venv, the tree we are decommissioning; it now names ytstream's. /healthz reports the serving mode and grace. Eight new proxy tests, 353 passing.
