First PyPI release: pip install factgate
A hallucination gate whose verdict is a comparison, not a judgement.
- Parameter-free verdict layer: VERIFIED / BLOCK / HELD by comparison alone, fail-closed
- Proof harness (
scripts/harden.py): 19 checks including an independent exact-rational oracle and 12 mutation tests, each proving one defence can fail - Measured: 0/366 leaks on the adversarial corpus, 99% routing coverage over 10 blind-authored domains
- Two supervised pilots: 110 answers across 4 documents, every verdict hand-confirmed, 0 trust breaches, 58% mean reviewer-load reduction
- Three first-time authors wrote clean fact sets from the docs alone, first try
