Gates recorded (nvenc-subframe-slice-output.md Phase 3): loss-harness curve identical streamed-vs-whole; adversarial security review clean; live .21 3-leg A/B — streamed 0 corrupted frames, p99 8527→5363 µs vs sliced-whole, first_slice_us ~500 µs of a ~1250 µs encode reaching the send thread; wire bytes rate-governed under CBR + 1-frame VBV (the ~1-2 % slice-header cost is absorbed by rate control, not added to the wire). GameStream: plane has zero code diff (own RTP packetizer; shares only untouched send_pacing); a live Moonlight re-test joins the standing owed Moonlight item. - resolve_slices(codec, default): env 1..=32 wins (1 = the NEW explicit single-slice escape), else the backend default — 4 on Linux direct-NVENC, 1 elsewhere. resolve_subframe(default_on): PUNKTFUNK_NVENC_SUBFRAME tri-state (0 = never, 1 = force, unset = backend default). - Linux nvenc_cuda: resolves both ONCE in query_caps — the sub-frame default is gated on the GPU's SUBFRAME_READBACK cap so an unsupporting GPU never has enableSubFrameWrite forced into its init params — and feeds the same resolved values to build_config, build_init_params (open AND in-place reconfigure) and the chunked-poll latch. - Windows: env-only as before (async path untouched, byte-identical config for unset env); LowLatencyConfig.slices + the explicit subframe param replace the shared env reads. - Tests: chunked e2e now runs at the DEFAULTS (no knobs); the fallback test becomes the escape test (SLICES=1 disarms; SUBFRAME=0 disarms while 4-slice encode continues on the plain poll path).
