# Change: Fix V2 API UI Integration Issues
## Why
After migrating from V1 batch-based architecture to V2 task-based architecture, several UI pages still reference V1 APIs or have incomplete implementations:
1. Results page (http://127.0.0.1:5173/results) doesn't display task details - uses non-existent V1 `getBatchStatus` API
2. Task History page markdown downloads produce empty files (0 bytes) - OCR service not generating markdown content
3. Task History page "View Details" button navigates to `/tasks/{taskId}` route that doesn't exist
4. Export page (http://127.0.0.1:5173/export) uses non-existent V1 `/api/v2/export` endpoint (404) and lacks multi-task selection
5. Admin Dashboard page loads but may have permission or API issues
These issues were discovered during testing with task ID: `88c6c2d2-37e1-48fd-a50f-406142987bdf` using file `Henkel-84-1LMISR4 (漢高).pdf`.
## What Changes
- Migrate ResultsPage from V1 batch API to V2 task API
- Fix OCR service markdown generation to produce non-empty .md files
- Add task detail page route and component at `/tasks/:taskId`
- Update ExportPage to use V2 download endpoints and support multi-task selection
- Verify and fix Admin Dashboard API integration and permissions
## Impact
- Affected specs: task-management, result-export
- Affected code:
- Frontend: `src/pages/ResultsPage.tsx`, `src/pages/ExportPage.tsx`, `src/App.tsx` (routes), new `src/pages/TaskDetailPage.tsx`
- Backend: `app/services/ocr_service.py` (markdown generation), `app/routers/tasks.py` (download endpoints)

# Result Export - Delta Changes
## ADDED Requirements
### Requirement: Export Interface
The Export page SHALL support downloading OCR results in multiple formats using V2 task APIs.
#### Scenario: Export page uses V2 download endpoints
- **WHEN** user selects a format and clicks export button
- **THEN** frontend SHALL call V2 endpoint `/api/v2/tasks/{task_id}/download/{format}`
- **AND** frontend SHALL NOT call V1 `/api/v2/export` endpoint (which returns 404)
- **AND** file SHALL download successfully
#### Scenario: Export supports multiple formats
- **WHEN** user exports a completed task
- **THEN** system SHALL support downloading as TXT, JSON, Excel, Markdown, and PDF
- **AND** each format SHALL use correct V2 download endpoint
- **AND** downloaded files SHALL contain task OCR results
### Requirement: Multi-Task Export Selection
The Export page SHALL allow users to select and export multiple tasks.
#### Scenario: Select multiple tasks for export
- **WHEN** Export page loads
- **THEN** page SHALL display list of user's completed tasks
- **AND** page SHALL provide checkboxes to select multiple tasks
- **AND** page SHALL NOT require batch ID from upload store (legacy V1 behavior)
#### Scenario: Export selected tasks
- **WHEN** user selects multiple tasks and clicks export
- **THEN** system SHALL download each selected task's results in chosen format
- **AND** downloaded files SHALL be named distinctly (e.g., `{task_id}_result.{ext}`)
- **AND** system MAY provide option to download as ZIP archive for multiple files
### Requirement: Export Configuration Persistence
Export settings (format, thresholds, templates) SHALL apply consistently to V2 task downloads.
#### Scenario: Apply confidence threshold to export
- **WHEN** user sets confidence threshold to 0.7 and exports
- **THEN** downloaded results SHALL only include OCR text with confidence >= 0.7
- **AND** threshold SHALL apply via V2 download endpoint query parameters
#### Scenario: Apply CSS template to PDF export
- **WHEN** user selects CSS template for PDF format
- **THEN** downloaded PDF SHALL use selected styling
- **AND** template SHALL be passed to V2 `/tasks/{id}/download/pdf` endpoint

# Task Management - Delta Changes
## ADDED Requirements
### Requirement: Task Result Generation
The OCR service SHALL generate both JSON and Markdown result files for completed tasks with actual content.
#### Scenario: Markdown file contains OCR results
- **WHEN** a task completes OCR processing successfully
- **THEN** the generated `.md` file SHALL contain the extracted text in markdown format
- **AND** the file size SHALL be greater than 0 bytes
- **AND** the markdown SHALL include headings, paragraphs, and formatting based on OCR layout detection
#### Scenario: Result files stored in task directory
- **WHEN** OCR processing completes for task ID `88c6c2d2-37e1-48fd-a50f-406142987bdf`
- **THEN** result files SHALL be stored in `storage/results/88c6c2d2-37e1-48fd-a50f-406142987bdf/`
- **AND** both `<filename>_result.json` and `<filename>_result.md` SHALL exist
- **AND** both files SHALL contain valid OCR output data
### Requirement: Task Detail View
The frontend SHALL provide a dedicated page for viewing individual task details.
#### Scenario: Navigate to task detail page
- **WHEN** user clicks "View Details" button on task in Task History page
- **THEN** browser SHALL navigate to `/tasks/{task_id}`
- **AND** TaskDetailPage component SHALL render
#### Scenario: Display task information
- **WHEN** TaskDetailPage loads for a valid task ID
- **THEN** page SHALL display task metadata (filename, status, processing time, confidence)
- **AND** page SHALL show markdown preview of OCR results
- **AND** page SHALL provide download buttons for JSON, Markdown, and PDF formats
#### Scenario: Download from task detail page
- **WHEN** user clicks download button for a specific format
- **THEN** browser SHALL download the file using `/api/v2/tasks/{task_id}/download/{format}` endpoint
- **AND** downloaded file SHALL contain the task's OCR results in requested format
### Requirement: Results Page V2 Migration
The Results page SHALL use V2 task-based APIs instead of V1 batch APIs.
#### Scenario: Load task results instead of batch
- **WHEN** Results page loads with a task ID in upload store
- **THEN** page SHALL call `apiClientV2.getTask(taskId)` to fetch task details
- **AND** page SHALL NOT call any V1 batch status endpoints
- **AND** task information SHALL display correctly
#### Scenario: Handle missing task gracefully
- **WHEN** Results page loads without a task ID
- **THEN** page SHALL display helpful message directing user to upload page
- **AND** page SHALL provide button to navigate to `/upload`
