 ## 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:** Currently PLACEHOLDER (Sprint 7). Redo scheduled next audio sprint (#453). Design brief below captures target register.
+- **Monologue chimes:** Re-generated in Sprint 9 (#453). Insert-tech prefix + Chimes template, 5s SAO generation trimmed to 0.8s.
 
 ## Assets
 
 | ID | Filename | Status | Bus | Method | Duration | Prompt/Notes | Sprint |
 |----|----------|--------|-----|--------|----------|-------------|--------|
-| UI-001 | `cursor_hover.ogg` | draft | UI Sounds | SAO | 50-100ms | Subtle tick/ping on entity hover (D-056). Insert-tech: clean, precise, synthetic. Almost subliminal — notice if missing, not if present. Needs trim to target duration (#453). | S7 #440 |
-| UI-002 | `implant_open.ogg` | draft | UI Sounds | SAO | 150-250ms | Rising tone when insert UI opens (radial menu, inventory, stance). Neural lattice powering up. Frequency sweep, harmonic shimmer. Needs trim (#453). | S7 #440 |
-| UI-003 | `fog_recognition.ogg` | draft | UI Sounds | SAO | 300-400ms | Warm organic chime at onset of cognitive delay (D-060). Character recognizing a person. Unresolved tone. Needs trim (#453). | S7 #440 |
-| UI-004 | `weapon_aim.ogg` | draft | UI Sounds | SAO | 100-150ms | Harder click/lock for weapon aim state. Mechanical, deliberate. SKETCH ONLY — no weapons in Sprint 7. Needs trim (#453). | S7 #440 |
-| UI-005 | `sfx_monologue_chime.ogg` | draft | UI Sounds | SAO | 500-1000ms | PLACEHOLDER. Soft crystalline tone, neural lattice surfacing a thought. Quiet, non-intrusive. Redo in next audio sprint (#453). See design brief below. | S7 #440 |
-| UI-006 | `sfx_monologue_chime_urgent.ogg` | draft | UI Sounds | SAO | 500-1000ms | PLACEHOLDER. Sharper variant for contradiction/anomaly. Brighter, more insistent. Redo in next audio sprint (#453). See design brief below. | S7 #440 |
-| UI-007 | `sfx_weapon_aim_lock.ogg` | draft | UI Sounds | SAO | 300-500ms | Sharp targeting lock-on confirmation for weapon aim. Clinical/dangerous, harder than general entity lock. Descending digital sweep with metallic precision click. | S8 #440 |
-| UI-008 | `sfx_stance_change.ogg` | draft | UI Sounds | SAO | 200-400ms | Soft mechanical mode-switch click for stance toggle (Walk/Sprint/Careful/Crouch). Subtle digital detent, nearly subliminal. Fires frequently — fatigue-safe. | S8 #440 |

 **Quality bar:** If the urgent chime feels like a quest marker ping, it has failed. If it feels like Ubisoft, it has failed. The delta between normal and urgent = "someone thinking quietly" vs "someone's eyes going slightly wide."
 
-**Placeholder spec (Sprint 7):**
-- Normal: pure sine 1.2kHz, 600ms, gentle attack, natural decay. Conservative volume.
-- Urgent: sine 1.2kHz + harmonic 2.4kHz, 400ms, sharper attack, 15% louder.
-- Deliberately undersized — obviously temporary. Ugly placeholders get replaced.
+**Sprint 9 generation spec:**
+- Normal: SAO 5s generation (insert-tech prefix + chimes template), CFG 7, 100 steps. Trimmed to 0.8s (attack + initial decay). LUFS normalized to -16.
+- Urgent: SAO 5s generation (insert-tech prefix + chimes template, sharper/brighter descriptors), CFG 8, 100 steps. Trimmed to 0.8s. Stronger attack (-6.3dB peak vs -15.3dB normal), more sustained energy.
