## What's Planned (Not Started)
### Security Audit
- **Current state**: Security properties under research
- **Cryptographic analysis**: Not yet completed
- **Formal verification**: Not yet performed
- **Timeline**: Future release (post-1.0)
### Performance Optimization
- **Profiling**: Limited profiling done
- **Bottleneck analysis**: Ongoing
- **Optimization passes**: Planned
- **Timeline**: Ongoing through 1.0
### Production Hardening
- **Stability**: API stabilization needed
- **Backward compatibility**: Not yet guaranteed
- **Production testing**: Needs validation
- **Timeline**: 1.0 release goal
### Advanced Features
- **Package isolation**: Design exists, not implemented
- **Selective decryption**: Concept phase
- **Differential updates**: Future enhancement
- **Timeline**: Post-1.0
## Known Issues
### Test Failures (Infrastructure)
- **Issue**: 4 tests fail due to disk space (OS error 28)
- **Tests affected**: `qa_comprehensive.rs` tests
- **Impact**: Infrastructure only, not code defects
- **Resolution**: Tests pass with sufficient disk space
### Deprecation Warnings
- **Issue**: `SparseVec::from_data()` deprecated
- **Impact**: Warnings in benchmarks and some tests
- **Severity**: Low - functionality unaffected
- **Resolution**: Migration to `encode_data()` planned
### API Instability
- **Issue**: APIs subject to change in alpha phase
- **Impact**: Breaking changes may occur
- **Severity**: Expected for alpha release
- **Resolution**: Will stabilize for 1.0
## Performance Characteristics (Preliminary)
These are preliminary measurements, not guaranteed:
- **Small files (<1KB)**: ~1-5ms encoding/decoding
- **Medium files (1-100KB)**: ~5-50ms encoding/decoding
- **Large files (>1MB)**: Varies, hierarchical encoding recommended
- **Memory usage**: ~100-500MB typical for 10,000 dimension vectors
- **Dimension**: Currently 10,000 with ~1% sparsity
**Note**: Performance optimization is ongoing. These numbers may change significantly.
## API Stability Roadmap
### Current (v0.20.0-alpha)
- **Unstable**: Breaking changes expected
- Core types and operations may change
- CLI interface may evolve
### Target (v1.0)
- **Stable**: Semantic versioning guarantees

### Planned Path
1. **v0.20.x-alpha**: Feature development, API refinement
2. **v0.90.0-beta**: API freeze, testing focus
3. **v1.0.0**: Stable release with guarantees
