## Mission: Phase 2 White-Box Adversarial Stress Testing (Tier 5)
Conduct white-box adversarial stress testing on the complete map redesign implementation:

### 1. Key Adversarial Stress Targets:
1. Procedural Generation & Compression:
   - Extreme seeds (`0`, `-1`, `2**31 - 1`, `2**32 - 1`, float seeds, string seeds).
   - Corrupted binary payloads (truncated byte arrays, invalid magic bytes, mismatched header sizes).
2. Runtime Tile Collision & Physics:
   - High-speed movement vectors ($dx = 100, dy = 100$) against corner pinch colliders.
   - Sliding along non-orthogonal walls and boundaries.
3. Fog of War & Minimap:
   - Corrupted or truncated `localStorage` Base64 strings.
   - Extreme zoom levels, dynamic window resizing, and rapid pause/unpause toggles.
4. AI Pathfinding & Combat Encounter:
   - Massive concurrent monster chase steering across complex obstacles.
   - Rapid multi-pack wipes, Boss Gate breach transitions, and waypoint safe zone boundary thrashing.

### 2. Verification Commands:
Execute and verify:
- `pytest tests/e2e/test_poe2_map_system_e2e.py -v` (81/81 tests)
- `pytest tests/unit/test_encounter_zones.py -v` (16/16 tests)
- `pytest tests/unit/test_tile_collision.py -v` (11/11 tests)
- `pytest tests/unit/test_fog_and_minimap.py -v` (14/14 tests)
- `pytest tests/unit/test_waypoint_safe_radius.py -v` (17/17 tests)
- `pytest tests/unit/test_monster_poise_and_leash.py -v` (10/10 tests)
- `node tools/perf/map_render_benchmark.js` (Must PASS, 0 stationary re-bakes)
- `node --expose-gc tools/perf/stress_test_grid_pathfinder.js` (Must PASS)
- `python tools/lint/check_code_and_doc_hygiene.py --strict` (0 hard cap violations)
- `pytest tests/unit/ -q` (all 1220 unit tests)

Write `handoff.md` in your directory with:
- Stress test results and empirical observations.
- Any uncovered failure modes or report `NO REMAINING GAPS`.
- Explicit verdict: `APPROVE` or `REQUEST_CHANGES`.
Send a message back to parent when complete.
