backend/scripts/run-migrations.js          # KEEP - essential setup
backend/scripts/run-production-migrations.js # KEEP - essential setup
```

### 2. Build and Cache Directories (REMOVE)

#### **Build Artifacts**
```bash
backend/dist/                    # Build output (regenerated)
frontend/dist/                   # Build output (regenerated)
backend/coverage/                # Test coverage (no longer needed)
```

#### **Cache Directories**
```bash
backend/.cache/                  # Build cache
frontend/.firebase/              # Firebase cache
frontend/node_modules/           # Dependencies (regenerated)
backend/node_modules/            # Dependencies (regenerated)
node_modules/                    # Root dependencies (regenerated)
```

### 3. Temporary and Log Files (REMOVE)

#### **Log Files**
```bash

```

#### **Upload Directories**
```bash

```

### 4. Development and IDE Files (REMOVE)

#### **IDE Configuration**

.claude/                         # Claude IDE settings
.kiro/                          # Kiro IDE settings
```

#### **Development Scripts**
```bash
# Root level scripts (mostly cleanup/utility)
cleanup_gcs.sh                   # GCS cleanup script
check_gcf_bucket.sh              # GCF bucket check
cleanup_gcf_bucket.sh            # GCF bucket cleanup
```

### 5. Redundant Configuration Files (REMOVE)

#### **Duplicate Configuration**
```bash
# Root level configs (backend/frontend have their own)
firebase.json                    # Root firebase config (duplicate)

storage.rules                    # Storage rules
package.json                     # Root package.json (minimal)
package-lock.json                # Root package-lock.json
```

### 6. SQL Setup Files (KEEP ESSENTIAL)

#### **Database Setup**
```bash
# KEEP - Essential database setup
backend/supabase_setup.sql       # Core database setup
backend/supabase_vector_setup.sql # Vector database setup
backend/vector_function.sql      # Vector functions

# REMOVE - Redundant

## 💾 Space Savings Estimate

### Files to Remove
- **Test Files**: ~50 files, ~500KB
- **Build Artifacts**: ~100MB (dist, coverage, node_modules)
- **Log Files**: ~200KB (regenerated)
- **Upload Files**: Variable size (using Firebase Storage)
- **IDE Files**: ~10KB
- **Redundant Configs**: ~50KB

### Total Estimated Savings
- **File Count**: ~100 files removed
- **Disk Space**: ~100MB+ saved
- **Repository Size**: Significantly reduced
- **Clarity**: Much cleaner structure

## ⚠️ Safety Considerations

### Before Cleanup
1. **Backup**: Ensure all important data is backed up
2. **Documentation**: All essential documentation is preserved
3. **Configuration**: Essential configs are kept
4. **Dependencies**: Package files are preserved for regeneration

### After Cleanup
1. **Test Build**: Run `npm install` and build process
2. **Verify Functionality**: Ensure system still works
3. **Update Documentation**: Remove references to deleted files
4. **Commit Changes**: Commit the cleanup

---

## 🎯 Benefits of Cleanup

### Immediate Benefits
1. **Cleaner Repository**: Easier to navigate and understand
2. **Reduced Size**: Smaller repository and faster operations
3. **Less Confusion**: No outdated or unused files
4. **Better Focus**: Only essential files remain

### Long-term Benefits
1. **Easier Maintenance**: Less clutter to maintain
2. **Faster Development**: Cleaner development environment
3. **Better Onboarding**: New developers see only essential files
4. **Reduced Errors**: No confusion from outdated files
