nx_vqoe_research_fetch.nx -- GROUND video-call QoE BENCHMARKING (operator 2026-07-03: "provide fps and stability and other measurements for video chats ... what benchmarking tools for video audio over distances like belarus and texas exist ... we have had too many false positives that our video chat is really good and we need honest feedback if we need more hardware or different hardware"). Banks the REAL measurement surface over sovereign TLS-1.3 (nx_research_engine, no curl): (1) VIDEO quality metrics: VMAF (Netflix, the industry reference), PSNR, SSIM, subjective methods (2) AUDIO quality: MOS, E-model (ITU G.107), PESQ, POLQA -- the mouth-to-ear standards (3) NETWORK QoE: latency/jitter/loss/goodput, end-to-end delay, QoE frameworks, packet-loss concealment (4) the TOOLS: netem-class network emulation, iperf, RIPE Atlas (REAL measured Texas<->Minsk paths), internet measurement platforms -- what we can consume + what we must build hardware-up (5) the PATH itself: Internet in Belarus (the family's real leg) Idempotent have-skip => resumable.
