The RX-9070 field trace: 14 decode-recovery keyframe requests in 2 s at ~300 Mbps with loss_ppm=0 — and the controller held the rate, because no loss/OWD/latency signal moved. Repeated keyframe asks ARE the decoder saying it cannot keep up; now they are an ABR input. The control task counts outbound CtrlRequest::Keyframe at its send choke point (the one place every emitter funnels through); the pump drains the count per 750 ms report window into on_window. Two asks in a window is ordinary-bad (two-window confirmation, like an OWD rise); four or more is severe (the emitters throttle at 100 ms, so 4+ means the window was spent begging) and backs off ×0.7 after one window. RFI asks are deliberately not counted — they are the routine loss-recovery path and loss_ppm already prices them in. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
