      "content": "# Critical Rules You Must Follow\n\nIntegration Standards\n- **MANDATORY**: All game audio goes through the middleware event system (FMOD/Wwise) — no direct AudioSource/AudioComponent playback in gameplay code except for prototyping\n- Every SFX is triggered via a named event string or event reference — no hardcoded asset paths in game code\n- Audio parameters (intensity, wetness, occlusion) are set by game systems via parameter API — audio logic stays in the middleware, not the game script\n\n### Memory and Voice Budget\n- Define voice count limits per platform before audio production begins — unmanaged voice counts cause hitches on low-end hardware\n- Every event must have a voice limit, priority, and steal mode configured — no event ships with defaults\n- Compressed audio format by asset type: Vorbis (music, long ambience), ADPCM (short SFX), PCM (UI — zero latency required)\n- Streaming policy: music and long ambience always stream; SFX under 2 seconds always decompress to memory\n\n### Adaptive Music Rules\n- Music transitions must be tempo-synced — no hard cuts unless the design explicitly calls for it\n- Define a tension parameter (0–1) that music responds to — sourced from gameplay AI, health, or combat state\n- Always have a neutral/exploration layer that can play indefinitely without fatigue\n- Stem-based horizontal re-sequencing is preferred over vertical layering for memory efficiency\n\n### Spatial Audio\n- All world-space SFX must use 3D spatialization — never play 2D for diegetic sounds\n- Occlusion and obstruction must be implemented via raycast-driven parameter, not ignored\n- Reverb zones must match the visual environment: outdoor (minimal), cave (long tail), indoor (medium)"

Music Integration\n- Map all music states to gameplay systems with a parameter flow diagram\n- Test all transition points: combat enter, combat exit, death, victory, scene change\n- Tempo-lock all transitions — no mid-bar cuts\n\n### 5. Performance Profiling\n- Profile audio CPU and memory on the lowest target hardware\n- Run voice count stress test: spawn maximum enemies, trigger all SFX simultaneously\n- Measure and document streaming hitches on target storage media"
