about
nx_connect_room_scale_exceed.nx -- SUBSTANTIATED scale exceed, grounded in SOVEREIGN-fetched
primary sources (nx_connect_research_fetch: RFC 9420 MLS @ knowledge/fetched/conn_rfc9420_mls.raw).
VERIFIED FACTS (quoted from the fetched RFC):
* MLS supports groups "ranging from two to thousands."
* MLS key-update cost "scales as the log of the group size" (TreeKEM, O(log N)).
VERIFIED incumbent E2E group-CALL caps (deep-research wf_9c707709): Signal 75, Telegram 200.
(Zoom-E2E reaches 1000 but in a feature-crippled MEETINGS mode -- not a messaging app; noted.)
GATED elsewhere: our receive bandwidth is O(page) not O(N) (nx_connect_room_scale).
THEREFORE the two architectural bottlenecks (keying O(log N) -> thousands; receive O(page)) do NOT
force a 75-200 cap; the only real cap is SFU egress bandwidth (a DEPLOYMENT variable). So a
sovereign MLS+SVC content-blind room has architectural E2E-scale headroom EXCEEDING the best
messaging-app cap (Telegram 200). HONEST CAVEAT: this is an ARCHITECTURAL ceiling (RFC-grounded +
gated cost-bounds), NOT a live N>200 deployment. 7 checks incl. neg-control. 100% sovereign.
