world-evidence-watch

A standing specialist (spec §8a) — run by the recheck loop on a schedule, not in round one. It reruns the trial / literature / ClinVar-relookup specialists against the fixed profile, then diffs against the stored baseline:

new_trials   = current_trial_ids - known_trial_ids
new_pmids    = pubmed.search(genes, mindate=last_checked)
new_biorxiv  = biorxiv.search(genes, since=last_checked)
reclassified = {v: now[v] for v in snapshot if now[v] != snapshot[v]}

• Empty diff -> one calm "No significant changes since your last check." entry.
• Non-empty -> one dated, hedged, cited timeline card per item.
• Update the baseline after each run.

bioRxiv is first-class (earliest signal). Every card passes the code gate.

STATUS: live — re-queries app.trials.search_trials + app.literature. search_literature(since=ctx.last_checked) and returns the current snapshot. The diff/baseline logic lives in app/recheck.py (diff_new_records by source_id), which turns genuinely-new items into hedged timeline cards and updates the baseline. Runs only when BWCLS_LIVE_SOURCES=1; empty snapshot -> calm "no significant changes".
