Methodology v0.2: computed tiers and first-class N/A grades
Tiers are now derived from a per-requirement checklist rather than assigned, and not-applicable / under-review became first-class grade states excluded from the composite score. Deployer-property vectors on open-weight models (data handling, compliance) moved from graded to not-applicable, changing the composite scores of the tagged models.
