feat: add Log Viewer to Web UI for browsing evaluation results#1191
Merged
Conversation
Add a new Log Viewer tab to the existing Web UI that lets users browse
locally stored evaluation outputs from the logs directory.
Backend (server.py):
- GET /logs/runs - scan logs directory and list all evaluation runs
- GET /logs/runs/{run_id}/results - return full results JSON for a run
- GET /logs/runs/{run_id}/samples/{task} - paginated sample browsing
- Path traversal protection and proper error handling
Frontend:
- New LogViewer.tsx component with left panel (run list) + right panel
(results metrics table, config summary, paginated sample viewer)
- Tab navigation in header to switch between Evaluate and Log Viewer
- Sample cards with color-coded sections: Input (neutral), Target (green),
Filtered Responses (blue), plus metric badges
- Consistent styling with existing monochrome design system
Add Load Image button to each sample card in the Log Viewer. Clicking it fetches the corresponding row from HuggingFace datasets server API (by dataset_path, split, doc_id from task config) and renders image columns inline. Images are cached in component state to avoid re-fetching. Backend: new GET /logs/dataset-row endpoint that proxies HF datasets server API with optional Bearer token auth. Frontend: configs field on RunResults interface, taskConfig memo, loadSampleImage callback, violet-styled Load Image button, inline image display with column name label, error display for failed loads.
… run switch and hide image load errors
