/**
* Standalone Adversarial Stress-Test Script for Milestone M2
* Diablo II Web DRLG Engine: Wilderness Connectivity & Transverse Barricades
*
* Requirements:
* 1. Stress-test Act 4 Lava Fissure flood-fill reachability across 50+ distinct seeds:
* - Perform full BFS flood-fill reachability from entrance across the 3 strategic rock bridges.
* - Assert walkable floor reachability >= 90% holds 100% of the time across all seeds.
* 2. Stress-test Act 5 Transverse Barricades across 50+ distinct seeds:
* - Assert barricades span horizontally across X in [8..W-8] when height > width with military gate at hubX.
* - Assert barricades span vertically across Y in [8..H-8] when width >= height with military gate at hubY.
* - Assert gates are open (no wall collision mask) and walkable.
* - Assert full end-to-end corridor traversability through the barricade gates.
*
* Act I's outdoor levels are generated by the DRLG port (src/game/drlg), not by generateWilderness;
* tests/drlg-act1-oracle.test.ts (bit-exact against native D2MOO) and tests/drlg-act1-invariants.test.ts
* cover them.
*
* Archetype: EMPIRICAL CHALLENGER
