#!/usr/bin/env bash
# stress_test.sh — The Only Script That Matters
#
# Runs the four-layer falsification suite for the Sovereign Array Stack.
# Every layer corresponds to a named theorem in ArrayLang/.
#
# Usage:
#   ./stress_test.sh              # all layers
#   ./stress_test.sh --layer 0    # Lean kernel only
#   ./stress_test.sh --layer 1    # property falsifier only
#   ./stress_test.sh --layer 3    # NP attack only (quick)
#   ./stress_test.sh --install    # install Python deps
#
# Pre-push hook:
#   echo './stress_test.sh' >> .git/hooks/pre-push && chmod +x .git/hooks/pre-push
#
# Pass criteria:
#   Layer 0 — 0 sorry, 0 custom axioms, all reductions terminate
#   Layer 1 — 0 counterexamples @ 100k shrunk examples
#   Layer 2 — Alive2: Verified (or skip if toolchain absent)
#   Layer 3 — 0 soundness violations on random 3-SAT instances
