This commit resolves several physics-related issues that were causing
unexpected behavior in ship and asteroid movement:
**Physics Sleep System**
- Fixed abrupt stops by preventing Havok from putting bodies to sleep
- Added PhysicsActivationControl.ALWAYS_ACTIVE for ship and asteroids
- Made ship sleep behavior configurable via shipPhysics.alwaysActive
- Sleep was causing sudden velocity zeroing at low speeds
**Center of Mass Issues**
- Discovered mesh-based physics calculated offset CoM: (0, -0.38, 0.37)
- Override ship center of mass to (0, 0, 0) to prevent thrust torque
- Applying force at offset CoM was creating unwanted pitch rotation
- Added debug logging to track mass properties
**Input Deadzone Improvements**
- Implemented smooth deadzone scaling (0.1-0.15 range)
- Replaced hard threshold cliff with linear interpolation
- Prevents abrupt control cutoff during gentle inputs
- Added VR mode check to disable keyboard fallback in VR
**Configuration System**
- Added DEFAULT_SHIP_PHYSICS constant as single source of truth
- Added tunable parameters: linearDamping, angularDamping, alwaysActive
- Added fuel consumption rates: linearFuelConsumptionRate, angularFuelConsumptionRate
- Tuned for 1 minute linear thrust, 2 minutes angular thrust at 60Hz
- All physics parameters now persist to localStorage
**Other Fixes**
- Changed orbit center to STATIC motion type (was ANIMATED)
- Fixed linear force application point (removed offset)
- Added ship initial velocity support from level config
- Changed physics update from every 10 frames to every physics tick
- Increased linear input threshold from 0.1 to 0.15

Add linear-clamped scoring system that rewards speed, accuracy, fuel
efficiency, and hull integrity. Scores are always positive with a 0.5x
multiplier floor for refueling/repairs.
Scoring Components:
- Create scoreCalculator module with configurable scoring logic
- Time multiplier: Exponential decay from par time (0.1x to 3.0x)
- Accuracy multiplier: Linear 1.0x to 2.0x based on hit percentage
- Fuel efficiency: Linear with 0.5x floor (handles refueling >100%)
- Hull integrity: Linear with 0.5x floor (handles deaths/repairs >100%)
- Star rating system: 0-3 stars per category (12 stars max)
Integration:
- Add calculateFinalScore() to GameStats
- Support parTime in level config metadata
- Auto-calculate par time from difficulty level in Level1
- Recruit: 300s, Pilot: 180s, Captain: 120s, Commander: 90s, Test: 60s
- Display comprehensive score breakdown on status screen
Status Screen Updates:
- Increase mesh size from 1.5x1.0m to 1.5x2.25m (portrait orientation)
- Increase texture from 1024x768 to 1024x1536 (fit all content)
- Add score display section with:
- Final score in gold with thousand separators
- Score multiplier breakdown for each category
- Unicode star ratings (★★★) per category
- Total stars earned (X/12)
Formula:
finalScore = 10,000 × time × accuracy × fuel × hull
All multipliers ≥ 0.5, ensuring scores are never negative even with
multiple refuels/deaths. System rewards balanced excellence across all
performance metrics.

Root cause: The old Sound API (new Sound()) is incompatible with
AudioEngineV2 in BabylonJS 8.32.0, causing silent failures where the
explosion.mp3 file was never fetched from the network.
Audio System Fixes:
- Migrate explosion sound from Sound class to AudioEngineV2.createSoundAsync()
- Use StaticSound with spatial property instead of old Sound API
- Configure audio engine with listenerEnabled and listenerAutoUpdate
- Attach audio listener to camera for proper 3D positioning
Spatial Audio Implementation:
- Use spatialEnabled: true with spatial-prefixed properties
- Attach sound to explosion node using sound.spatial.attach()
- Properly detach and cleanup after explosion finishes (850ms)
- Configure exponential distance model with 500 unit max distance
Technical Changes:
- Replace new Sound() with await audioEngine.createSoundAsync()
- Change _explosionSound type from Sound to StaticSound
- Update imports: Sound → StaticSound
- Use sound.spatial.attach(node) instead of attachToMesh()
- Use sound.spatial.detach() for cleanup
- Remove incompatible getVolume() calls
Audio Engine Configuration:
- Add CreateAudioEngineAsync options for spatial audio support
- Attach listener to camera after unlock in both level flows
- Enable listener auto-update for VR camera movement tracking
This fixes the explosion sound loading and enables proper 3D spatial
audio with distance attenuation.

Modified physics recorder to automatically save all captured data to IndexedDB:
- Auto-saves every 10 seconds in batches (non-blocking)
- Creates unique session ID for each gameplay session
- Buffers snapshots between saves to minimize IndexedDB writes
- Saves any remaining buffered data on disposal
- All data preserved indefinitely in browser storage
Technical implementation:
- Auto-save buffer collects snapshots between 10-second intervals
- performAutoSave() copies buffer and clears immediately (non-blocking)
- Async save happens in background without impacting frame rate
- Session ID format: "session-{timestamp}" for easy identification
- Ring buffer (30s) still available for quick exports
Recording flow:
1. Recording starts when XR pose is set
2. Every frame adds snapshot to ring buffer AND auto-save buffer
3. Every 10 seconds, auto-save buffer is flushed to IndexedDB
4. On disposal, any remaining buffered frames are saved
5. All data accessible via existing storage APIs
Performance: Minimal impact - saves happen async every 10s, not per frame.
