## Mission
Empirically stress-test the remediated encounter zone architecture, pack leashing, full test suite non-regression, and performance benchmark:
1. Re-test Ambush Minion Wall Fallback:
   Run randomized tests on POIs placed in 1-tile wide dead-ends and against walls. Verify 0 minions spawn in blocked tiles.
2. Re-test Pack Clear Idempotency:
   Simulate 100 rapid AoE pack clears. Verify `zoneEncounterProgress` strictly preserves `clearedPacks <= totalPacks`.
3. Non-Regression & Benchmark:
   - `pytest tests/unit/test_encounter_zones.py -v` (16/16 PASS)
   - `pytest tests/unit/test_waypoint_safe_radius.py -v` (17/17 PASS)
   - `pytest tests/unit/test_monster_poise_and_leash.py -v` (10/10 PASS)
   - `pytest tests/unit/test_fog_and_minimap.py -v` (14/14 PASS)
   - `pytest tests/unit/test_tile_collision.py -v` (11/11 PASS)
   - `pytest tests/e2e/test_poe2_map_system_e2e.py -v` (81/81 PASS)
   - `node tools/perf/map_render_benchmark.js` (Must PASS with 0 stationary re-bakes)
   - `pytest tests/unit/ -q` (all unit tests must PASS)
   - `python tools/lint/check_code_and_doc_hygiene.py --strict` (0 violations)
