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

+# hook post-task
+
+Execute post-task cleanup, performance analysis, and memory storage.
+
+## Usage
+
+```bash
+npx claude-flow hook post-task [options]
+```
+
+## Options
+
+- `--task-id, -t <id>` - Task identifier for tracking
+- `--analyze-performance` - Generate performance metrics (default: true)
+- `--store-decisions` - Save task decisions to memory
+- `--export-learnings` - Export neural pattern learnings
+- `--generate-report` - Create task completion report
+
+## Examples
+
+### Basic post-task hook
+
+```bash
+npx claude-flow hook post-task --task-id "auth-implementation"
+```
+
+### With full analysis
+
+```bash
+npx claude-flow hook post-task -t "api-refactor" --analyze-performance --generate-report
+```
+
+### Memory storage
+
+```bash
+npx claude-flow hook post-task -t "bug-fix-123" --store-decisions --export-learnings
+```
+
+### Quick cleanup
+
+```bash
+npx claude-flow hook post-task -t "minor-update" --analyze-performance false
+```
+
+## Features
+
+### Performance Analysis
+
+- Measures execution time
+- Tracks token usage
+- Identifies bottlenecks
+- Suggests optimizations
+
+### Decision Storage
+
+- Saves key decisions made
+- Records implementation choices
+- Stores error resolutions
+- Maintains knowledge base
+
+### Neural Learning
+
+- Exports successful patterns
+- Updates coordination models
+- Improves future performance
+- Trains on task outcomes
+
+### Report Generation
+
+- Creates completion summary
+- Documents changes made
+- Lists files modified
+- Tracks metrics achieved
+
+## Integration
+
+This hook is automatically called by Claude Code when:
+
+- Completing a task
+- Switching to a new task
+- Ending a work session
+- After major milestones
+
+Manual usage in agents:
+
+```bash
+# In agent coordination
+npx claude-flow hook post-task --task-id "your-task-id" --analyze-performance true
+```
+
+## Output
+
+Returns JSON with:
+
+```json
+{
+  "taskId": "auth-implementation",
+  "duration": 1800000,
+  "tokensUsed": 45000,
+  "filesModified": 12,
+  "performanceScore": 0.92,
+  "learningsExported": true,
+  "reportPath": "/reports/task-auth-implementation.md"
+}
+```
