- Stop is a no-op when the collected player unit is already gone (raw systemctl stop exits 5 on the Frame; verified 2026-09-29). - Surface systemd-run stderr when the player can't start. - Keep the copy error if the cleanup ssh also fails; reject upload names that the play path can never accept. - Allow 60 s for play (ffprobe 30 s + systemd-run 15 s remote). - Docs: four-hour cap is unconditional; no delete action yet; fix a garbled timing sentence.
