Read before acting on this dossier: scores come from a deterministic rubric grader whose agreement with an independent LLM judge is provisional (kappa 0.156 measured 2026-06-27, n=97, lenient reference-free judge — not a validation). The deployment tier above is operator-declared at run time, not verified; sovereign-lane scores grade written answers about deployment topics, not deployment capability. Category scores at n=25 carry wide confidence intervals (typically ±8–12 pts) — differences under ~15 pts are usually not separable. This dossier is measurement evidence, not a procurement recommendation or a regulatory compliance finding.
