clawd d81e403f01 Phase 06 Tier 1: Complete Backend Implementation - Recovery Tracking & Swap System

COMPLETED TASKS:
✅ 06-01: Workout Swap System
   - Added swapped_from_id to workout_logs
   - Created workout_swaps table for history
   - POST /api/workouts/:id/swap endpoint
   - GET /api/workouts/available endpoint
   - Reversible swaps with audit trail

✅ 06-02: Muscle Group Recovery Tracking
   - Created muscle_group_recovery table
   - Implemented calculateRecoveryScore() function
   - GET /api/recovery/muscle-groups endpoint
   - GET /api/recovery/most-recovered endpoint
   - Auto-tracking on workout log completion

✅ 06-03: Smart Workout Recommendations
   - GET /api/recommendations/smart-workout endpoint
   - 7-day workout analysis algorithm
   - Recovery-based filtering (>30% threshold)
   - Top 3 recommendations with context
   - Context-aware reasoning messages

DATABASE CHANGES:
- Added 4 new tables: muscle_group_recovery, workout_swaps, custom_workouts, custom_workout_exercises
- Extended workout_logs with: swapped_from_id, source_type, custom_workout_id, custom_workout_exercise_id
- Created 7 new indexes for performance

IMPLEMENTATION:
- Recovery service with 4 core functions
- 2 new route handlers (recovery, smartRecommendations)
- Updated workouts router with swap endpoints
- Integrated recovery tracking into POST /api/logs
- Full error handling and logging

TESTING:
- Test file created: /backend/test/phase-06-tests.js
- Ready for E2E and staging validation

STATUS: Ready for frontend integration and production review
Branch: feature/06-phase-06

Raft Consensus Manager

Implements and manages the Raft consensus algorithm for distributed systems with strong consistency guarantees.

Core Responsibilities

Leader Election: Coordinate randomized timeout-based leader selection
Log Replication: Ensure reliable propagation of entries to followers
Consistency Management: Maintain log consistency across all cluster nodes
Membership Changes: Handle dynamic node addition/removal safely
Recovery Coordination: Resynchronize nodes after network partitions

Implementation Approach

Leader Election Protocol

Execute randomized timeout-based elections to prevent split votes
Manage candidate state transitions and vote collection
Maintain leadership through periodic heartbeat messages
Handle split vote scenarios with intelligent backoff

Log Replication System

Implement append entries protocol for reliable log propagation
Ensure log consistency guarantees across all follower nodes
Track commit index and apply entries to state machine
Execute log compaction through snapshotting mechanisms

Fault Tolerance Features

Detect leader failures and trigger new elections
Handle network partitions while maintaining consistency
Recover failed nodes to consistent state automatically
Support dynamic cluster membership changes safely

Collaboration

Coordinate with Quorum Manager for membership adjustments
Interface with Performance Benchmarker for optimization analysis
Integrate with CRDT Synchronizer for eventual consistency scenarios
Synchronize with Security Manager for secure communication
