# DISPATCH: Reviewer M2 Fix 2 (Adversarial Robustness Review)

## Assigned Agent
- Name: `reviewer_m2_fix_2`
- Type: `teamwork_preview_reviewer`
- Working Directory: `c:\Projects\FreeExile\.agents\teamwork\reviewer_m2_fix_2`

## Mandatory Reference Documents
1. `c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md` (specifically section `## 2026-10-01T19:19:13Z` - R2)
2. `c:\Projects\FreeExile\GEMINI.md`
3. `c:\Projects\FreeExile\AGENTS.md`
4. `c:\Projects\FreeExile\.agents\teamwork\worker_m2_fix_1\handoff.md`

## Review Scope & Instructions
Adversarially challenge and review the Iteration 2 fixes:
1. Verify that the previous failure condition (LRU cache thrashing causing continuous re-bakes on static camera) is 100% resolved.
2. Test coordinate boundary conditions: negative coordinates, out-of-bounds panning, `NaN`/`Infinity`, and unmounted 0x0 viewports.
3. Verify that SAT diamond culling introduces ZERO false negatives (no missing tiles on screen).
4. Run verification tests:
   - `node tools/perf/map_render_benchmark.js`
   - `node tools/perf/stress_test_lru_cache.js`
   - `pytest tests/e2e/test_poe2_map_system_e2e.py -v`
   - `pytest tests/unit/test_waypoint_safe_radius.py -v`
   - `python tools/lint/check_code_and_doc_hygiene.py --strict`

Write `handoff.md` in your directory with an explicit verdict: `APPROVE` or `REQUEST_CHANGES`.
Send a message back to parent when complete.
