about

nx_audio_serve.nx -- the SOVEREIGN audiobook player BRAIN (SC34/35/37), server-side Nishi code (operator: the player capabilities ARE nishi-code APIs, not browser JS). Binds 127.0.0.1 only. The browser is a dumb native <audio> client; THIS daemon does the work: GET /audio/<slug> -> the zero-JS player.html (rendered by nx_audio_render) GET /audio/<slug>/track -> serve the audio bytes; honors `Range: bytes=X-Y` (206) so <audio> seeks/streams GET /audio/<slug>/track?sleep=N -> SLEEP TIMER: caps the served stream to N*BYTES_PER_MIN -> playback ends (SC34) POST /audio/<slug>/bookmark (pos=BYTE) -> stores the position server-side -> 303 (SC35 + SC37 cross-device) GET /audio/<slug>/resume -> returns the stored position {"pos":N} (the client seeks there) (SC37) Reuses the proven nx_vizsla_serve HTTP pattern (handle-mode gate hook + gallery_serve socket idiom). The position store is a per-slug file (reader/<slug>/audio_pos.txt). license_tier: ORIGINAL
