nx_comms_perf_census.nx -- MEASURED PERFORMANCE census for the /video comms stack (operator
2026-07-02: "s class exceed performant on research as of today -- best fps sound responsiveness").
The PERF third of the management triad (breadth = nx_comms_rival_census, capability = the gates).
THREE evidence classes, none asserted:
MEASURED = gg_gate_green over the persisted room gate logs (last-verdict rule, anti-liar) --
these are REAL runs: the Jitsi SFU h2h, QoE-MOS, FEC/ARQ resilience, adaptive jitter
buffer, BWE, ABR hysteresis, L4S queueing, audio PLC.
SHIPPED = file-evidence of the 2026-07-02 fps rung (ladder TABLE in the wasm core, 10->20fps
ceiling; client reads rungs from the core).
BEHIND = the named debts, detected MECHANICALLY so they self-flip when fixed: the client still
ships deprecated createScriptProcessor (AudioWorklet = the banked SOTA), still JPEG
toBlob (WebCodecs hw = banked), fixed playout margins (organ gated, client unwired),
and the glass-to-glass netem h2h vs rivals has NEVER run (the exceed standard's bar).
LIVE axis: fresh funcheck video PASS required -- a dead room cannot GREEN a perf census.
GROUNDED: refuses without the 13 banked perf_*.raw sources. expect_exit: 0 license_tier: ORIGINAL
