This tribal sovereignty action involves civil rights (4.2) due to denial of membership/benefits to Freedmen descendants based on ancestry, and rule_of_law (3.5) as it affects legal status and rights within tribal jurisdiction. Policy_change mechanism adds 1.25x modifier. Single_state/narrow scope reduces to 0.75x. Severity multipliers: durability 1.15 (administrative blocks can persist), reversibility 1.1 (requires policy reversal), precedent 1.2 (affects tribal membership standards). Base: (3.5×0.18 + 4.2×0.14)×1.25×0.75×1.52 = 12.3. B-score: Layer1 moderate outrage (3) around racial exclusion, limited meme_ability (1), some novelty (2), moderate media appeal (2.5) = 4.7×0.55. Layer2: minor mismatch (1), pattern_match (2) with historical tribal-Freedmen tensions = 1.8×0.45×1.0 = 0.81. Total B: 3.4. Delta: +5.8. Neither list qualifies (A<25, B<25).
