Major improvements to preprocessing controls:
Backend:
- Add contrast_strength (0.5-3.0) and sharpen_strength (0.5-2.0) to PreprocessingConfig
- Auto-detection now calculates optimal strength based on image quality metrics:
- Lower contrast → Higher contrast_strength
- Lower edge strength → Higher sharpen_strength
- Disable binarization in auto mode (rarely beneficial)
- CLAHE clipLimit now scales with contrast_strength
- Sharpening uses unsharp mask with variable strength
Frontend:
- Add strength sliders for contrast and sharpen in manual mode
- Sliders show current value and strength level (輕微/正常/強/最強)
- Move binarize option to collapsible "進階選項" section
- Updated i18n translations for strength labels

Implement user-configurable PP-StructureV3 parameters to allow fine-tuning OCR behavior
from the frontend. This addresses issues with over-merging, missing small text, and
document-specific optimization needs.
Backend:
- Add PPStructureV3Params schema with 7 adjustable parameters
- Update OCR service to accept custom parameters with smart caching
- Modify /tasks/{task_id}/start endpoint to receive params in request body
- Parameter priority: custom > settings default
- Conditional caching (no cache for custom params to avoid pollution)
Frontend:
- Create PPStructureParams component with collapsible UI
- Add 3 presets: default, high-quality, fast
- Implement localStorage persistence for user parameters
- Add import/export JSON functionality
- Integrate into ProcessingPage with conditional rendering
Testing:
- Unit tests: 7/10 passing (core functionality verified)
- API integration tests for schema validation
- E2E tests with authentication support
- Performance benchmarks for memory and initialization
- Test runner script with venv activation
Environment:
- Remove duplicate backend/venv (use root venv only)
- Update test runner to use correct virtual environment
OpenSpec:
- Archive fix-pdf-coordinate-system proposal
- Archive frontend-adjustable-ppstructure-params proposal
- Create ocr-processing spec
- Update result-export spec

- Add ProcessingTrackEnum, ProcessingOptions, ProcessingMetadata schemas
- Add DocumentAnalysisResponse for document type detection
- Update /start endpoint with dual-track query parameters
- Add /analyze endpoint for document type detection with confidence scores
- Add /metadata endpoint for processing track information
- Add /download/unified endpoint for UnifiedDocument format export
- Update tasks.md to mark Section 6 API updates as completed

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.
