nx_comms_rival_fetch.nx

nx_comms_rival_fetch.nx -- THIN structured COMMS-RIVAL research source organ. COMPOSES nx_research_engine (sovereign fetch->extract->bank). Operator 2026-07-02: "benchmark our codec, streaming, etc against the best like jitsi and zoom and telegram and discord and have all of their features like texting and contacts". So: ground the rival-benchmark census on REAL sourced rival products/architectures -- never assumptions (Rule 4). The four named rivals + their protocol depth (MTProto, Signal Protocol, Matrix) + the SFU implementations (videobridge/mediasoup/janus/BBB = the sfu-multiparty long-pole yardsticks) + the IM feature-matrix pages (texting/contacts/presence parity). Already banked, NOT refetched: webrtc/opus/av1/vp9/avc/hevc/mls/stun/nat/simulcast/svc/quic/moq (knowledge/fetched/conn_*, codec_*, p2pdist_*). Banks clean .txt -> knowledge/library/. expect_exit: 0 license_tier: ORIGINAL
