"""
test_apex_genius_verdicts.py — Tests for APEX PRIME v36Ω GENIUS LAW Verdicts.

Verifies the GENIUS LAW judiciary integration:
1. Hard floors remain absolute gates (VOID regardless of G)
2. GENIUS LAW (G, C_dark) refines verdicts beyond floor checks
3. Decision hierarchy: Hard floors → C_dark VOID → Low G VOID → 888_HOLD → Soft PARTIAL → GENIUS surface → SEAL

Phase 2 (v36.0.0): APEX PRIME uses G/C_dark for verdict decisions.
