Add missing file upload functionality to V2 API that was removed
during V1 to V2 migration. Update frontend to use v2 API endpoints.
Backend changes:
- Add /api/v2/upload endpoint in main.py for file uploads
- Import necessary dependencies (UploadFile, hashlib, TaskFile)
- Upload endpoint creates task, saves file, and returns task info
- Add UploadResponse schema to task.py schemas
- Update tasks router imports for consistency
Frontend changes:
- Update API_VERSION from 'v1' to 'v2' in api.ts
- Update UploadResponse type to match V2 API response format
(task_id instead of batch_id, single file instead of array)
This fixes the 404 error when uploading files from the frontend.

- Fixed WSL CUDA library path in ~/.bashrc
- Upgraded PaddlePaddle from 3.0.0 to 3.2.1
- Verified fused_rms_norm_ext API is now available
- Enabled chart recognition in ocr_service.py
- Updated CHART_RECOGNITION.md to reflect enabled status
Chart recognition now supports:
✅ Chart type identification
✅ Data extraction from charts
✅ Axis and legend parsing
✅ Converting charts to structured data

Chart Recognition Status Investigation:
- OpenSpec limitation record is ACCURATE but based on old PaddlePaddle 3.0.0 (Mar 2025)
- PaddlePaddle has released multiple updates (3.1.x, 3.2.x, latest: 3.2.2 Nov 2025)
- The fused_rms_norm_ext API MAY now be available in newer versions
Root Cause:
- PaddleOCR-VL chart recognition requires paddle.incubate.nn.functional.fused_rms_norm_ext
- PaddlePaddle 3.0.0 only provided fused_rms_norm (base version)
- Not a compatibility issue - PaddleOCR 3.x is fully compatible with PaddlePaddle 3.x
- Issue is missing API, not version mismatch
What Still Works (Even with Chart Recognition Disabled):
✅ Chart detection and extraction as images
✅ Table recognition (with nested formulas/images)
✅ Formula recognition
✅ Text recognition (OCR core)
What's Disabled:
❌ Deep chart understanding (type, data extraction, axis/legend parsing)
❌ Converting chart content to structured data
Created Files:
1. CHART_RECOGNITION.md - Comprehensive guide explaining:
- Current limitation status and history
- What works vs what's disabled
- How to verify if newer PaddlePaddle versions support the API
- How to enable chart recognition if API becomes available
- Troubleshooting and performance considerations
2. backend/verify_chart_recognition.py - Verification script to:
- Check if fused_rms_norm_ext API is available
- Display current PaddlePaddle version
- Provide actionable recommendations
Next Steps for Users:
1. Run: conda activate tool_ocr && python backend/verify_chart_recognition.py
2. If API is available, enable chart recognition in ocr_service.py:217
3. Update OpenSpec if limitation is resolved in newer versions

Root Cause Fixed:
- Tests were connecting to production MySQL database instead of test database
- Solution: Monkey patch database module before importing app to use SQLite :memory:
Changes:
1. **conftest.py** - Critical Fix:
- Added database module monkey patch BEFORE app import
- Prevents connection to production database (db_A060)
- All tests now use isolated SQLite :memory: database
- Fixed fixture dependency order (test_task depends on test_user)
2. **test_tasks.py**:
- Fixed test_delete_task: Accept 204 No Content (correct HTTP status)
3. **test_admin.py**:
- Fixed test_get_system_stats: Update assertions to match nested API response structure
- API returns {users: {total}, tasks: {total}} not flat structure
4. **test_integration.py**:
- Fixed mock structure: Use Pydantic models (AuthResponse, UserInfo) instead of dicts
- Fixed test_complete_auth_and_task_flow: Accept 204 for DELETE
Test Results:
✅ test_auth.py: 5/5 passing (100%)
✅ test_tasks.py: 6/6 passing (100%)
✅ test_admin.py: 4/4 passing (100%)
✅ test_integration.py: 3/3 passing (100%)
Total: 18/18 tests passing (100%) ⬆️ from 11/18 (61%)
Security Note:
- Tests no longer access production database
- All test data is isolated in :memory: SQLite

Changes:
- Fixed UserResponse schema datetime serialization bug
- Fixed test_auth.py mock structure for external auth service
- Updated conftest.py to create fresh database per test
- Ran full test suite and verified results
Test Results:
✅ test_auth.py: 5/5 passing (100%)

Total: 11/18 tests passing (61%)
Known Issues:
1. Fixture isolation: test_user sometimes gets admin email
2. Admin API response structure doesn't match test expectations
3. Integration tests need mock fixes
Production Bug Fixed:
- UserResponse schema now properly serializes datetime fields to ISO format strings

PaddleOCR-VL chart recognition model requires `fused_rms_norm_ext` API
which is not available in PaddlePaddle 3.0.0 stable release.
Changes:
- Set use_chart_recognition=False in PP-StructureV3 initialization
- Remove unsupported show_log parameter from PaddleOCR 3.x API calls
- Document known limitation in openspec proposal
- Add limitation documentation to README
- Update tasks.md with documentation task for known issues
Impact:
- Layout analysis still detects/extracts charts as images ✓
- Tables, formulas, and text recognition work normally ✓
- Deep chart understanding (type detection, data extraction) disabled ✗
- Chart to structured data conversion disabled ✗
Workaround: Charts saved as image files for manual review

PaddlePaddle 3.0.0b2 has "Illegal instruction" error on current CPU.
Downgrade to stable 2.6.2 which works but uses different API.
Changes:
- Auto-detect PaddlePaddle version at runtime
- Use 'device' parameter for 3.x (device="gpu:0" or "cpu")
- Use 'use_gpu' + 'gpu_mem' parameters for 2.x
- Apply to both get_ocr_engine() and get_structure_engine()
- Log PaddlePaddle version in initialization messages
Current setup:
- paddlepaddle-gpu==2.6.2 (stable, CUDA compiled)
- paddleocr==3.3.1
- paddlex==3.3.9

PaddleOCR 3.x changed the API:
- Removed: use_gpu=True/False and gpu_mem=<value>
- Added: device="gpu:0" or device="cpu"
Changes:
- Updated get_ocr_engine() to use device parameter
- Updated get_structure_engine() to use device parameter
- GPU mode: device="gpu:{gpu_device_id}"
- CPU mode: device="cpu"
This fixes the "ValueError: Unknown argument: gpu_mem" runtime error.
