grounding: C2 attestation configuration decided - word-trigrams win
Three-way calibration over 553 labeled claims under the pre-stated rule: word-trigram unattested share (AUC 0.694) beats every tokengrams stream configuration at the current reference scale - char n=12..24 plateau at 0.677-0.640, GPT-2 token n=3..8 at 0.646-0.588, and the QUIP-canonical char n=30/50 SATURATE (~100% unattested for accepted and rejected alike): our 230M-char reference sits ~4 orders below the web-scale corpora that configuration presumes, so contrast lives at coarse word granularity. Engine (tokengrams) settled regardless; queued follow-ups: u32 word-id stream so the winning signal serves from the base engine (retiring the hand-rolled sqlite), and a full-corpus reference rebuild + re-test, since reference size binds the finer signals. Breadth-corpus re-test still gates production thresholds. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_012AgUm5EcRKbT3duVFMbrQD
