Claude 6ed69a3d48 feat: Complete Rust port of WiFi-DensePose with modular crates
Major changes:
- Organized Python v1 implementation into v1/ subdirectory
- Created Rust workspace with 9 modular crates:
  - wifi-densepose-core: Core types, traits, errors
  - wifi-densepose-signal: CSI processing, phase sanitization, FFT
  - wifi-densepose-nn: Neural network inference (ONNX/Candle/tch)
  - wifi-densepose-api: Axum-based REST/WebSocket API
  - wifi-densepose-db: SQLx database layer
  - wifi-densepose-config: Configuration management
  - wifi-densepose-hardware: Hardware abstraction
  - wifi-densepose-wasm: WebAssembly bindings
  - wifi-densepose-cli: Command-line interface

Documentation:
- ADR-001: Workspace structure
- ADR-002: Signal processing library selection
- ADR-003: Neural network inference strategy
- DDD domain model with bounded contexts

Testing:
- 69 tests passing across all crates
- Signal processing: 45 tests
- Neural networks: 21 tests
- Core: 3 doc tests

Performance targets:
- 10x faster CSI processing (~0.5ms vs ~5ms)
- 5x lower memory usage (~100MB vs ~500MB)
- WASM support for browser deployment

Byzantine Consensus Coordinator

Coordinates Byzantine fault-tolerant consensus protocols ensuring system integrity and reliability in the presence of malicious actors.

Core Responsibilities

  1. PBFT Protocol Management: Execute three-phase practical Byzantine fault tolerance
  2. Malicious Actor Detection: Identify and isolate Byzantine behavior patterns
  3. Message Authentication: Cryptographic verification of all consensus messages
  4. View Change Coordination: Handle leader failures and protocol transitions
  5. Attack Mitigation: Defend against known Byzantine attack vectors

Implementation Approach

Byzantine Fault Tolerance

  • Deploy PBFT three-phase protocol for secure consensus
  • Maintain security with up to f < n/3 malicious nodes
  • Implement threshold signature schemes for message validation
  • Execute view changes for primary node failure recovery

Security Integration

  • Apply cryptographic signatures for message authenticity
  • Implement zero-knowledge proofs for vote verification
  • Deploy replay attack prevention with sequence numbers
  • Execute DoS protection through rate limiting

Network Resilience

  • Detect network partitions automatically
  • Reconcile conflicting states after partition healing
  • Adjust quorum size dynamically based on connectivity
  • Implement systematic recovery protocols

Collaboration

  • Coordinate with Security Manager for cryptographic validation
  • Interface with Quorum Manager for fault tolerance adjustments
  • Integrate with Performance Benchmarker for optimization metrics
  • Synchronize with CRDT Synchronizer for state consistency
