* feat(eval): add report quality evaluation module
Addresses issue #773 - How to evaluate generated report quality objectively.
This module provides two evaluation approaches:
1. Automated metrics (no LLM required):
- Citation count and source diversity
- Word count compliance per report style
- Section structure validation
- Image inclusion tracking
2. LLM-as-Judge evaluation:
- Factual accuracy scoring
- Completeness assessment
- Coherence evaluation
- Relevance and citation quality checks
The combined evaluator provides a final score (1-10) and letter grade (A+ to F).
Files added:
- src/eval/__init__.py
- src/eval/metrics.py
- src/eval/llm_judge.py
- src/eval/evaluator.py
- tests/unit/eval/test_metrics.py
- tests/unit/eval/test_evaluator.py
* feat(eval): integrate report evaluation with web UI
This commit adds the web UI integration for the evaluation module:
Backend:
- Add EvaluateReportRequest/Response models in src/server/eval_request.py
- Add /api/report/evaluate endpoint to src/server/app.py
Frontend:
- Add evaluateReport API function in web/src/core/api/evaluate.ts
- Create EvaluationDialog component with grade badge, metrics display,
and optional LLM deep evaluation
- Add evaluation button (graduation cap icon) to research-block.tsx toolbar
- Add i18n translations for English and Chinese
The evaluation UI allows users to:
1. View quick metrics-only evaluation (instant)
2. Optionally run deep LLM-based evaluation for detailed analysis
3. See grade (A+ to F), score (1-10), and metric breakdown
* feat(eval): improve evaluation reliability and add LLM judge tests
- Extract MAX_REPORT_LENGTH constant in llm_judge.py for maintainability
- Add comprehensive unit tests for LLMJudge class (parse_response,
calculate_weighted_score, evaluate with mocked LLM)
- Pass reportStyle prop to EvaluationDialog for accurate evaluation criteria
- Add researchQueries store map to reliably associate queries with research
- Add getResearchQuery helper to retrieve query by researchId
- Remove unused imports in test_metrics.py
* fix(eval): use resolveServiceURL for evaluate API endpoint
The evaluateReport function was using a relative URL '/api/report/evaluate'
which sent requests to the Next.js server instead of the FastAPI backend.
Changed to use resolveServiceURL() consistent with other API functions.
* fix: improve type accuracy and React hooks in evaluation components
- Fix get_word_count_target return type from Optional[Dict] to Dict since it always returns a value via default fallback
- Fix useEffect dependency issue in EvaluationDialog using useRef to prevent unwanted re-evaluations
- Add aria-label to GradeBadge for screen reader accessibility
* feat(web): add multi-format report export (Markdown, HTML, PDF, Word, Image)
* fix: correct import order for docx (lint error)
* fix(web): address Copilot review comments for multi-format export
- Add i18n support for dropdown menu items (en/zh)
- Add DOMPurify for HTML sanitization (XSS protection)
- Fix async handling for canvas.toBlob with Promise wrapper
- Add toast notifications for export errors
- Fix Tooltip + DropdownMenuTrigger nesting (accessibility)
- Ensure container cleanup in finally block
* fix(web): enhance markdown parsing for PDF and Word export
- Add list support (bullet and numbered) for PDF export
- Add parseInlineMarkdown helper for Word export to handle bold, italic, code, links
- Add list support for Word export (bullet and numbered)
- Address Copilot review comments from PR #756
* fix(web): address PR review feedback for multi-format export
- Extract PDF formatting magic numbers into PDF_CONSTANTS
- Add Tooltip wrapper for download dropdown button
- Reduce triggerDownload cleanup timeout from 1000ms to 100ms
- Use marked.Lexer.lexInline for robust markdown parsing
- Add console.warn for image export cleanup errors
- Add numbering config for Word document ordered lists
- Fix CSS class typo: px-5pb-20 -> px-5 pb-20
- Remove unreachable dead code in parseInlineMarkdown

Add defensive checks before removeChild to prevent 'Failed to execute removeChild' error when the element has already been removed from DOM. Wrap URL.revokeObjectURL in finally block to ensure proper resource cleanup.
