"""
tests/test_void_stress.py — v41.3 Semantic Governance Stress Test

This test suite validates the 3-layer semantic governance:
- Layer 1: RED_PATTERNS instant VOID detection
- Layer 2: compute_metrics_from_task() heuristics
- Layer 3: APEX PRIME judgment

Test Categories:
1. RED_PATTERNS detection (instant VOID)
2. Heuristic metric computation
3. Safe queries (should SEAL)
4. Edge cases and boundary conditions
