- Ped speech plays: speech manager -> library -> the living world's two streams, with queue / interrupts and the
near / far lines by distance; levels and filters from the retail mechanism (filters equal to the recomp's, gain
median within 0.5 %). Silent and logged when the opt-in speech decode is absent.
- NPC skater: wheels and clothing on its own instance and a bail grunt; tricks, treatment and footsteps stay off for
NPCs as in retail.
- Per-model ped data (shoe class, voice, far threshold) and traffic engine records per model exported by setup;
traffic relative-speed input and front / rear sound points; world hosts process before the mixer tick.
- Test mod: opt-in (off by default), higher world-object limits (48 per mod, 128 total), a per-second summary log.
- Specs published in docs/hails-additions/audio-specs/; code comments point at them; test data paths behind env vars
(no .local defaults).
