## 📊 Current Status

### TypeScript Coverage
- **Source code**: 100% TypeScript ✅
- **Unit tests**: 100% TypeScript (24 tests) ✅
- **Test infrastructure**: 100% TypeScript ✅
- **Test runners**: 100% TypeScript (4 files) ✅
- **Integration tests**: 100% TypeScript (8 files) ✅
- **Demo files**: 100% TypeScript (4 files) ✅

### Build & Test Status
- ✅ **TypeScript compilation**: Successful (no errors)
- ✅ **Unit tests**: 24/24 passing (100%)
- ✅ **Build**: Successful
- ✅ **All migrations verified**: Build and tests pass after each migration

### Remaining JavaScript Files (Lower Priority)
- **Middleware tests** (`test/middleware/`): ~10 files
- **Enterprise tests** (`test/enterprise/`): ~5 files
- **Analysis scripts** (`test/analysis/`): ~4 files
- **Tool scripts** (`test/tools/`): ~2 files

These are typically larger, more complex test files that can be migrated incrementally if needed.

## 📦 Package.json Updates
