"""
Tests for `_verify_report_factoids` and `_annotate_unverified_factoids`.

Acceptance:
  - factoids are extracted from the report
  - verified against positive extracts
  - refuted factoids (verified='false') are appended to the report
  - 'uncertain' is NOT marked inline (too many false positives)
  - without extracts: all factoids stay uncertain, no crash
  - on LLM failure: graceful, the report stays unchanged
