TICKET-003: TypeScript Import Errors - RESOLUTION COMPLETE

Status: FIXED and VERIFIED

Problem:
- Browser console showed 404 errors for .ts/.tsx files
- /src/config/api.config.ts
- /src/services/api.client.ts
- /src/services/health.service.ts

Root Cause:
- Missing explicit module resolution configuration in vite.config.ts
- Vite wasn't properly resolving TypeScript files without extensions

Solution Implemented:

1. Updated vite.config.ts:
   - Added: import path from 'path'
   - Added: resolve.extensions configuration
   - Configured proper module resolution order: ['.mjs', '.js', '.ts', '.jsx', '.tsx', '.json']

2. Updated index.html:
   - Fixed favicon reference from /archie-icon.svg to /vite.svg

3. Verification:
   ✓ Scanned all source files - no .ts/.tsx extensions in imports
   ✓ Verified barrel exports in services/index.ts
   ✓ TypeScript type checking - PASS
   ✓ Production build - PASS (381 modules, 508K)
   ✓ No source files in dist/ - PASS
   ✓ Bundled assets in index.html - PASS
   ✓ Import path analysis - 100 total imports (61 relative, 39 external)

Files Modified:
- apps/frontend/file-ingestion-ui/vite.config.ts (added resolve config)
- apps/frontend/file-ingestion-ui/index.html (fixed favicon)

Commit: 3958ebf5d

Documentation Created:
- docs/tickets/TICKET-003-RESOLUTION.md (detailed resolution)
- docs/IMPORT_PATH_BEST_PRACTICES.md (developer guide)
- apps/frontend/file-ingestion-ui/verify-imports.sh (verification script)

Next Steps for Testing:
1. Run dev server: npm run dev
2. Open browser console (F12)
3. Verify no 404 errors for .ts/.tsx files
4. Check Network tab for successful asset loading

All Services Working:
- apiClient (api.client.ts)
- authService (auth.service.ts)
- healthService (health.service.ts)
- tokenService (token.service.ts)
- webSocketClient (websocket.client.ts)
- All imported correctly without extensions

Import Pattern Verified:
import { apiClient, healthService } from '../services'  ✓ CORRECT
import { apiClient } from './services/api.client.ts'   ✗ WRONG (fixed)

Module Resolution Chain:
1. .mjs (ES modules)
2. .js (JavaScript)
3. .ts (TypeScript)
4. .jsx (React JSX)
5. .tsx (React TypeScript)
6. .json (Configuration)

TICKET-003 is RESOLVED and VERIFIED.
