nx_comms_perf_fetch.nx -- THIN structured COMMS-PERFORMANCE research source organ. COMPOSES nx_research_engine. Operator 2026-07-02: "s class exceed performant on research as of today so that we get the best fps sound responsiveness". Grounds the PERF ladder on REAL sourced SOTA (Rule 4): AUDIO responsiveness (Web Audio quantum/AudioWorklet vs the deprecated ScriptProcessor our client uses; echo cancellation; audio-latency science), VIDEO fps (WebCodecs hw encode vs our JPEG-toBlob; requestVideoFrameCallback; OffscreenCanvas; Motion-JPEG characteristics; frame-rate science), NETWORK smoothness (jitter/packet-delay-variation = the NetEQ problem; end-to-end delay), and the MEASUREMENT yardsticks (QoE; VMAF = the metric for the rival h2h).
