This Supreme Court petition represents substantive constitutional action targeting humanitarian protections for a specific migrant population. A-score: Election driver (3.5) reflects immigration as key political issue; rule_of_law (3.0) for challenging established protection framework; separation (2.5) for executive branch seeking judicial override; civil_rights (4.0) HIGH for direct impact on vulnerable population's legal status and due process rights. Policy_change mechanism with federal scope yields 1.15×1.2 modifiers. Severity multipliers: durability 1.2 (Supreme Court decisions create lasting precedent), reversibility 1.1 (difficult to reverse high court rulings), precedent 1.15 (could affect broader asylum/protection frameworks). Base 24.86 × 1.518 = 38.7. B-score: Layer1 generates moderate hype (outrage_bait 6.5 for targeting vulnerable migrants, media_friendliness 7.0 for clear narrative). Layer2 strategic value (mismatch 5.0, timing 6.0 for political moment). Intentionality 7/15 (political timing, narrative alignment, policy signaling) yields 0.55 weight. Final B: 22.6. Delta: +16.1 clearly exceeds +10 threshold with A≥25, qualifying as List A constitutional damage event with real legal mechanism and measurable civil rights impact.
