+# Type Safety Implementation Status
+
+## ✅ COMPLETED (Phase 1 - Foundation)
+
+### Core Infrastructure
+- ✅ Enhanced ESLint with strict type checking rules
+- ✅ Fixed logger.ts with proper typing
+- ✅ Fixed errorHandler.ts with getErrorMessage & hasErrorCode utilities
+- ✅ Created comprehensive type definition files:
+  - `src/types/supabase-session.ts` - AAL & session types
+  - `src/types/company-data.ts` - Company database records
+  - `src/types/photos.ts` - Photo types with guards
+  - `src/types/location.ts` - Location data with guards
+  - `src/types/company.ts` - Company form data & technical specs
+  - `src/types/identity.ts` - OAuth & identity management
+  - `src/types/privacy.ts` - Privacy settings
+  - `src/types/notifications.ts` - Notification types
+  - `src/types/timeline.ts` - Timeline events
+  - `src/types/ride-credits.ts` - Ride credit filters
+  - `supabase/functions/_shared/types.ts` - Edge function types
+
+### Fixed Files
+- ✅ `src/components/auth/MFARemovalDialog.tsx` - Removed 13 `as any` casts
+- ✅ `src/lib/entitySubmissionHelpers.ts` - Fixed type safety
+- ✅ `src/hooks/moderation/*.ts` - Fixed all 4 moderation hooks
+- ✅ `src/components/moderation/FieldComparison.tsx` - Typed formatCompactValue
+- ✅ `src/components/moderation/ItemEditDialog.tsx` - Typed handleSubmit & photos
+- ✅ `supabase/functions/update-novu-subscriber/index.ts` - Full type safety
+- ✅ `supabase/functions/trigger-notification/index.ts` - Full type safety
+
+## 🔄 IN PROGRESS (Remaining ~300 violations)
+
+### Catch Blocks (~300 files)
+- Need to replace all `catch (error)` with `catch (error: unknown)`
+- Use `getErrorMessage(error)` for error handling
+
+### Component Type Safety (~70 files)
+- Admin components function parameters
+- Search & filter components
+- UI components (calendar, chart)
+- Upload components
+- Profile & settings components
+
+### Edge Functions (~8 remaining)
+- process-selective-approval (critical)
+- create-novu-subscriber
+- detect-location
+- export-user-data
+- Other backend functions
+
+## 📋 NEXT STEPS
+
+1. **Enable TypeScript Strict Mode** (when ready):
+   ```json
+   // tsconfig.json
+   "strict": true,
+   "noImplicitAny": true,
+   "strictNullChecks": true
+   ```
+
+2. **Continue Batch Fixes**:
+   - Batch 1: Remaining catch blocks (automated)
+   - Batch 2: Component props & parameters
+   - Batch 3: Edge functions
+   - Batch 4: Final validation
+
+3. **Testing**: Full regression test after each batch
+
+## 🎯 PROGRESS METRICS
+
+- **Foundation**: 100% ✅
+- **Type Definitions**: 100% ✅
+- **Error Handling**: 15% (50/350 violations fixed)
+- **Component Types**: 10% (8/78 files fixed)
+- **Edge Functions**: 20% (2/10 functions fixed)
+
+**Overall Progress**: ~20% of 5-day plan complete
+
+## 📝 NOTES
+
+- All new types use proper type guards
+- Error handling now uses `unknown` type
+- Edge functions have shared type definitions
+- Foundation is solid for remaining work
