nx_live_xlate_call.nx

nx_live_xlate_call.nx -- the CALL-LEVEL live-translation router for a 2-party video call. Each peer has a locale; a spoken utterance (recognized text) is translated into the LISTENER's language so each person reads the other in their own script. Same-locale = passthrough. Composes nx_mt_ruen. This is the deterministic, on-device call logic for "a girl in Belarus (RU) talking to a boy in Texas (EN)". The audio->text step (ASR) is the declared interface + RESEARCHER long-pole (V-ASR-1); transport is the existing relay (cross-NAT by construction). license_tier: ORIGINAL
