The gpu-session TrackedEncoder wrapper delegates every Encoder method by hand, so the new reconfigure_bitrate fell through to the trait's false default and EVERY bitrate change silently took the rebuild+IDR path — the live .21 A/B caught it (host log said 'rebuilt', never 'in place'). Also: - punktfunk-probe --rebitrate KBPS:SECS — headless mid-stream SetBitrate validator (cursor-wiggles so a damage-driven idle desktop keeps publishing frames through the switch). Live-verified on .21: one NVENC session open, then 'encoder bitrate reconfigured in place (adaptive bitrate — no IDR)' at 20→60 Mbps. - on-hardware nvenc_cuda reconfigure smoke test (20→60→10 Mbps in place, zero IDRs — green on the RTX 5070 Ti). - BitrateChanged doc no longer claims the switch costs an IDR.
