## Generation Approach
- **All UI sounds:** Generated via Stable Audio Open with sonic family prefix prompts, then trimmed/normalized/converted via `audio-post pipeline`.
- **Monologue chimes:** Re-generated in Sprint 9 (#453). Insert-tech prefix + Chimes template, 5s SAO generation trimmed to 0.8s.
- **Monologue chimes:** Replaced in Sprint 10 (#327) with manual synthesis. Insert-tech aesthetic: pure sine harmonics, mathematical envelope, no SAO. Previous S9 SAO versions were acknowledged placeholders per D-038 amendment.
