GPU ingest pipeline (direct follow-ons to #161)

#164 — HLS preview → h264_nvenc (remove the last CPU encoder)
#165 — GPU deinterlace (yadif_cuda/bwdif_cuda) — needs ffmpeg rebuilt with CUDA filters
#166 — live NVENC/GPU encode telemetry on the Cluster screen
#167 — per-recorder GPU affinity (replace NVIDIA_VISIBLE_DEVICES=all)

These four together are the path to the 8-signals-per-node capacity goal (design §5).

Operator safety / UX

#163 — recorder codec presets + codec/container/audio validation guard (prevents the silent-broken-master footguns: PCM-in-MP4, HEVC-in-MXF)

Multi-vendor capture

#168 — source-backend abstraction for Deltacast/AJA (land before the hardware, design §6)

#162 — bug: local-spawn recorder stop lacks finalize grace → corrupt MP4 / stuck-live

Validated & shipped this session

#161 merged to main: NVENC All-Intra HEVC capture, GPU sidecar passthrough, validated codec config + Dockerfile fix. Confirmed end-to-end on the L4 (SDI → hevc_nvenc master with live GPU utilization → h264 proxy → browser playback). Regression sweep (SRT/RTMP/SDI/upload/playback) 5/5 green.

Still needs a human

Confirm Premiere can edit the growing fragmented-MOV over SMB (file-level growing property proven; Premiere-specific behavior unverified).
ZXP→UXP swap on the home-page Premiere Pro button (queued, post-merge).

Feature ideas surfaced while building/validating the All-Intra HEVC NVENC ingest path (#161, now merged to main).
