4. **Performance**: Batch operations and memory pooling for efficiency
### GPU Integration Requirements
1. **Compute shaders**: WGSL implementations for parallel operations
2. **Buffer management**: Efficient GPU memory allocation and data transfer
3. **Adaptive dispatch**: CPU fallback for small problems, GPU for large scale
4. **Platform detection**: Graceful degradation when GPU unavailable
### Testing Requirements
1. **WASM**: wasm-bindgen-test for browser environment testing
2. **GPU**: Conditional testing that skips when GPU unavailable
3. **Integration**: Cross-crate compatibility testing
4. **Performance**: Benchmarks comparing CPU/GPU/WASM performance

## Testing Coverage Status
### Current Test Infrastructure
- **Unit tests**: All main crates have comprehensive unit tests
- **Integration tests**: Cross-crate compatibility testing
- **WASM tests**: Limited to amari-core and amari-network
- **GPU tests**: Conditional tests that skip in CI environments
### Coverage Gaps
- **WASM**: Most crates lack web-specific testing
- **GPU**: Performance benchmarks missing
- **Cross-platform**: Limited testing on different GPU vendors
- **Memory**: Memory usage and leak testing incomplete
## Technical Debt
### WASM
- Outdated relativistic bindings need API updates
- Missing error handling patterns in some modules
- Performance optimization opportunities in batch operations
### GPU
- Some pipeline objects created but never used (dead code warnings)
- Limited fallback strategies for GPU initialization failures
- Missing memory usage monitoring and optimization
### General
- Workspace dependency warnings for default-features
- Inconsistent feature flag patterns across crates
- Documentation gaps for integration examples
