The keyframe backstop added for the black LG TV only arms while AUs are actually going into the decoder (`fed > fed_at_output`) — deliberately, so an idle stream never asks for anything. That leaves its mirror image uncovered: a session that receives NOTHING. A decoder cannot be starved of output when it was handed no input, so no signal in either loop fires, and the session sits connected — audio, input and the control plane all alive — behind a black surface. That state is what a user just reported as "the stats are all basically 0": fps and Mb/s are counted at AU receipt (`note_received`), so all-zero stats with a drawn overlay means the decode thread started and received nothing. Same bug as the black screen, seen from the HUD. Both loops now watch for it: nothing received 1.5 s into a session ⇒ request a keyframe and log it, re-asking every 2 s while it lasts. Where it can help it does — the host encoding fine while every picture references an IDR this client never saw is precisely a keyframe request away. Where it can't, the log line is the point: "no video received N ms into the session" separates "the host never sent a picture" from "we received AUs and lost them", which no previous black-screen report could distinguish. Not a root cause. The remaining occurrences are still unattributed — this makes the next report diagnosable and recovers the case that is ours to recover.
