Backend (app/api.py):
- GET /api/benchmark/models — returns installed models grouped by adapter
type (ZeroShotAdapter, RerankerAdapter, GenerationAdapter, Unknown);
reads _MODELS_DIR via app.models so test overrides are respected
- GET /api/benchmark/run — add model_names query param (comma-separated);
when set, passes --models <names...> to benchmark_classifier.py
- GET /api/stats — add benchmark_results field from benchmark_results.json
Frontend:
- BenchmarkView: collapsible Model Selection panel with per-category
checkboxes, select-all per category (supports indeterminate state),
collapsed summary badge ("All models (N)" or "N of M selected");
model_names only sent when a strict subset is selected
- StatsView: Benchmark Results table (accuracy, macro_f1, weighted_f1)
with best-model highlighting per metric; hidden when no results exist
