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 pre-edit
+
+Execute pre-edit validations and agent assignment before file modifications.
+
+## Usage
+
+```bash
+npx claude-flow hook pre-edit [options]
+```
+
+## Options
+
+- `--file, -f <path>` - File path to be edited
+- `--auto-assign-agent` - Automatically assign best agent (default: true)
+- `--validate-syntax` - Pre-validate syntax before edit
+- `--check-conflicts` - Check for merge conflicts
+- `--backup-file` - Create backup before editing
+
+## Examples
+
+### Basic pre-edit hook
+
+```bash
+npx claude-flow hook pre-edit --file "src/auth/login.js"
+```
+
+### With validation
+
+```bash
+npx claude-flow hook pre-edit -f "config/database.js" --validate-syntax
+```
+
+### Manual agent assignment
+
+```bash
+npx claude-flow hook pre-edit -f "api/users.ts" --auto-assign-agent false
+```
+
+### Safe editing with backup
+
+```bash
+npx claude-flow hook pre-edit -f "production.env" --backup-file --check-conflicts
+```
+
+## Features
+
+### Auto Agent Assignment
+
+- Analyzes file type and content
+- Assigns specialist agents
+- TypeScript → TypeScript expert
+- Database → Data specialist
+- Tests → QA engineer
+
+### Syntax Validation
+
+- Pre-checks syntax validity
+- Identifies potential errors
+- Suggests corrections
+- Prevents broken code
+
+### Conflict Detection
+
+- Checks for git conflicts
+- Identifies concurrent edits
+- Warns about stale files
+- Suggests merge strategies
+
+### File Backup
+
+- Creates safety backups
+- Enables quick rollback
+- Tracks edit history
+- Preserves originals
+
+## Integration
+
+This hook is automatically called by Claude Code when:
+
+- Using Edit or MultiEdit tools
+- Before file modifications
+- During refactoring operations
+- When updating critical files
+
+Manual usage in agents:
+
+```bash
+# Before editing files
+npx claude-flow hook pre-edit --file "path/to/file.js" --validate-syntax
+```
+
+## Output
+
+Returns JSON with:
+
+```json
+{
+  "continue": true,
+  "file": "src/auth/login.js",
+  "assignedAgent": "auth-specialist",
+  "syntaxValid": true,
+  "conflicts": false,
+  "backupPath": ".backups/login.js.bak",
+  "warnings": []
+}
+```
