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

+# Self-Healing Workflows
+
+## Purpose
+Automatically detect and recover from errors without interrupting your flow.
+
+## Self-Healing Features
+
+### 1. Error Detection
+Monitors for:
+- Failed commands
+- Syntax errors
+- Missing dependencies
+- Broken tests
+
+### 2. Automatic Recovery
+
+**Missing Dependencies:**
+```
+Error: Cannot find module 'express'
+→ Automatically runs: npm install express
+→ Retries original command
+```
+
+**Syntax Errors:**
+```
+Error: Unexpected token
+→ Analyzes error location
+→ Suggests fix through analyzer agent
+→ Applies fix with confirmation
+```
+
+**Test Failures:**
+```
+Test failed: "user authentication"
+→ Spawns debugger agent
+→ Analyzes failure cause
+→ Implements fix
+→ Re-runs tests
+```
+
+### 3. Learning from Failures
+Each recovery improves future prevention:
+- Patterns saved to knowledge base
+- Similar errors prevented proactively
+- Recovery strategies optimized
+
+**Pattern Storage:**
+```javascript
+// Store error patterns
+mcp__claude-flow__memory_usage({
+  "action": "store",
+  "key": "error-pattern-" + Date.now(),
+  "value": JSON.stringify(errorData),
+  "namespace": "error-patterns",
+  "ttl": 2592000 // 30 days
+})
+
+// Analyze patterns
+mcp__claude-flow__neural_patterns({
+  "action": "analyze",
+  "operation": "error-recovery",
+  "outcome": "success"
+})
+```
+
+## Self-Healing Integration
+
+### MCP Tool Coordination
+```javascript
+// Initialize self-healing swarm
+mcp__claude-flow__swarm_init({
+  "topology": "star",
+  "maxAgents": 4,
+  "strategy": "adaptive"
+})
+
+// Spawn recovery agents
+mcp__claude-flow__agent_spawn({
+  "type": "monitor",
+  "name": "Error Monitor",
+  "capabilities": ["error-detection", "recovery"]
+})
+
+// Orchestrate recovery
+mcp__claude-flow__task_orchestrate({
+  "task": "recover from error",
+  "strategy": "sequential",
+  "priority": "critical"
+})
+```
+
+### Fallback Hook Configuration
+```json
+{
+  "PostToolUse": [{
+    "matcher": "^Bash$",
+    "command": "npx claude-flow hook post-bash --exit-code '${tool.result.exitCode}' --auto-recover"
+  }]
+}
+```
+
+## Benefits
+- 🛡️ Resilient workflows
+- 🔄 Automatic recovery
+- 📚 Learns from errors
+- ⏱️ Saves debugging time
