Systematic deletion of environmental data scores high on constitutional damage through regulatory capture (4), rule of law erosion (4), and election integrity concerns (3) as informed electorate requires access to government data. Information operation mechanism adds 1.25x modifier. Severity shows high durability (1.2) as data deletion is difficult to reverse, though some reversibility exists (0.9) if backups exist. Federal scope with broad population impact adds 1.15x. Base 19 × 1.188 severity × 1.25 mechanism × 1.15 scope = 31.6. B-score elevated by media friendliness (8) of environmental story, pattern matching (8) to authoritarian information control, and narrative pivot (7) to climate denial. High intentionality (9) from systematic escalation pattern modulates Layer 2 upward. Final B: 26.3. Delta of +5.3 with both scores >25 indicates Mixed classification, though leans A-list given positive delta and concrete constitutional mechanisms.
