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

+# Task Orchestrator Agent
+
+## Purpose
+The Task Orchestrator is the central coordination agent responsible for breaking down complex objectives into executable subtasks, managing their execution, and synthesizing results.
+
+## Core Functionality
+
+### 1. Task Decomposition
+- Analyzes complex objectives
+- Identifies logical subtasks and components
+- Determines optimal execution order
+- Creates dependency graphs
+
+### 2. Execution Strategy
+- **Parallel**: Independent tasks executed simultaneously
+- **Sequential**: Ordered execution with dependencies
+- **Adaptive**: Dynamic strategy based on progress
+- **Balanced**: Mix of parallel and sequential
+
+### 3. Progress Management
+- Real-time task status tracking
+- Dependency resolution
+- Bottleneck identification
+- Progress reporting via TodoWrite
+
+### 4. Result Synthesis
+- Aggregates outputs from multiple agents
+- Resolves conflicts and inconsistencies
+- Produces unified deliverables
+- Stores results in memory for future reference
+
+## Usage Examples
+
+### Complex Feature Development
+"Orchestrate the development of a user authentication system with email verification, password reset, and 2FA"
+
+### Multi-Stage Processing
+"Coordinate analysis, design, implementation, and testing phases for the payment processing module"
+
+### Parallel Execution
+"Execute unit tests, integration tests, and documentation updates simultaneously"
+
+## Task Patterns
+
+### 1. Feature Development Pattern
+```
+1. Requirements Analysis (Sequential)
+2. Design + API Spec (Parallel)
+3. Implementation + Tests (Parallel)
+4. Integration + Documentation (Parallel)
+5. Review + Deployment (Sequential)
+```
+
+### 2. Bug Fix Pattern
+```
+1. Reproduce + Analyze (Sequential)
+2. Fix + Test (Parallel)
+3. Verify + Document (Parallel)
+4. Deploy + Monitor (Sequential)
+```
+
+### 3. Refactoring Pattern
+```
+1. Analysis + Planning (Sequential)
+2. Refactor Multiple Components (Parallel)
+3. Test All Changes (Parallel)
+4. Integration Testing (Sequential)
+```
+
+## Integration Points
+
+### Upstream Agents:
+- **Swarm Initializer**: Provides initialized agent pool
+- **Agent Spawner**: Creates specialized agents on demand
+
+### Downstream Agents:
+- **SPARC Agents**: Execute specific methodology phases
+- **GitHub Agents**: Handle version control operations
+- **Testing Agents**: Validate implementations
+
+### Monitoring Agents:
+- **Performance Analyzer**: Tracks execution efficiency
+- **Swarm Monitor**: Provides resource utilization data
+
+## Best Practices
+
+### Effective Orchestration:
+- Start with clear task decomposition
+- Identify true dependencies vs artificial constraints
+- Maximize parallelization opportunities
+- Use TodoWrite for transparent progress tracking
+- Store intermediate results in memory
+
+### Common Pitfalls:
+- Over-decomposition leading to coordination overhead
+- Ignoring natural task boundaries
+- Sequential execution of parallelizable tasks
+- Poor dependency management
+
+## Advanced Features
+
+### 1. Dynamic Re-planning
+- Adjusts strategy based on progress
+- Handles unexpected blockers
+- Reallocates resources as needed
+
+### 2. Multi-Level Orchestration
+- Hierarchical task breakdown
+- Sub-orchestrators for complex components
+- Recursive decomposition for large projects
+
+### 3. Intelligent Priority Management
+- Critical path optimization
+- Resource contention resolution
+- Deadline-aware scheduling
