about

nx_audio_session.nx -- concrete audio-session subtype. Extends nx_media_session by embedding it as the FIRST field of the struct, so any `*nx_audio_session` casts safely to `*nx_media_session` for the base portion (classic C inheritance pattern; works because NishiLang structs are byte-flat). Composes: nx_media_session.nx -- base lifecycle + vtable nx_codec.nx -- codec abstraction; encode/decode dispatch nx_audio_capture.nx -- mic capture abstract + null/synth backends nx_audio_playback.nx -- speaker playback abstract + null backend Consumers (audio session is composed by): nx_video_room.nx -- audio + video + chat + signaling nx_call.nx -- 1:1 family/friends call nx_game_voice.nx -- spatial audio in voxels nx_iot_intercom.nx -- kitchen tablet <-> garage nx_cli_meet.nx -- terminal-only audio genealogy_id: nx_media_session_q10 + nx_codec_q10 + nx_voice_codec_v1 + nx_lpc_q15 + nx_voice_frame_q10 lineage_id: nx_audio_session_q10
