"""Run the curated query set through federated_search and capture per-source diagnostics.

Produces a JSON corpus (one record per query) suitable for HF Dataset upload.
Each record captures:
  - query + domain + expected_strong_sources
  - per-source raw count (before dedup)
  - deduplicated count
  - top 10 deduplicated papers with title/year/source/url/doi
  - timing (wall-clock seconds per source)
