Cross-subject containment
Every test packet carries unique canary details. A pass means no information from one subject's packet ever appeared in another subject's output — a single confirmed leak fails the run outright.

Methodology
Controlled synthetic cases; atomic claim grounding vs. the source packet; per-run canary registry for cross-patient containment testing; physician-adjudicated low-confidence, fabrication, containment, and severe-omission claims; severity-weighted tiering. Rates carry 95% Wilson confidence intervals, and tiers gate on the conservative (upper) bound of the interval rather than the point estimate.
