A-score 24.4: Multi-state coordination on book bans creates moderate constitutional concern. Civil_rights (4.0) reflects First Amendment/intellectual freedom issues in public education. Rule_of_law (3.5) captures judicial process being used to normalize censorship. Election (2.5) and capture (2.5) reflect coordinated GOP state action. Norm_erosion_only mechanism reduces modifier to 0.85 (no formal policy yet, just amicus brief). Multi-state scope adds 1.25x. Severity multipliers: durability 1.15 (precedent-setting coordination), reversibility 1.05 (can be challenged), precedent 1.2 (21-state brief is significant). B-score 28.6: Layer1 (14.3): High outrage_bait (8.0) on book banning/censorship, strong media_friendliness (7.5) for culture war narrative, moderate meme_ability (6.5), lower novelty (4.0) as book ban debates ongoing. Layer2 (12.85): Pattern_match (8.0) fits established culture war playbook, narrative_pivot (7.0) shifts from substantive issues, mismatch (6.0) between brief's impact and attention. Intentionality 9/15 (coordinated timing, culture war framing) yields 0.55 weight. Delta: -4.2 (B exceeds A). Both scores near threshold (A=24.4, B=28.6), delta within mixed range, qualifies as Mixed event with B-list lean due to culture war amplification exceeding actual constitutional damage from an amicus brief.
