**Last visited**: 2026-10-01T20:25:00Z
**Current status**: Milestone M2 Forensic Integrity Audit complete. Verdict: CLEAN. Handoff report generated.
**Completed steps**:
1. Read ORIGINAL_REQUEST.md (§R2) and PROJECT.md (Development mode confirmed).
2. Inspected source code of `tile_map_renderer.js` (278 lines), `world_renderer.js` (452 lines), and `map_render_benchmark.js` (154 lines).
3. Verified zero hardcoded outputs, zero facade functions, zero fake timing loops.
4. Empirically verified dynamic memory computation of `getMemoryUsage()` (8,388,608 bytes empty -> 8,399,408 bytes with 120x90 grid).
5. Empirically verified LRU cache invariance: 4 slots strictly allocated on init, 0 leaks, 0 new canvas allocations during continuous pan.
6. Empirically verified dirty flag chunk re-baking: 4 initial bakes, 0 bakes on clean frame, exactly 1 bake on dirty chunk invalidation.
7. Verified edge case resilience against NaN, Infinity, negative, and extreme coordinates.
8. Independently executed `node tools/perf/map_render_benchmark.js`: PASS (FPS ~57,015 >= 30, blits 4.4 <= 6, RAM 8.01 MB <= 8.02 MB).
9. Independently executed `pytest tests/e2e/test_poe2_map_system_e2e.py -v`: 81/81 PASS (100% across Tiers 1-4).
10. Independently executed `pytest tests/unit/test_waypoint_safe_radius.py -v`: 17/17 PASS.
11. Independently executed `pytest tests/unit/test_wilderness_map_generator.py -v`: 26/26 PASS.
12. Independently executed `python tools/lint/check_code_and_doc_hygiene.py --strict`: PASS (0 hard cap violations).
13. Independently executed `python tools/security/run_independent_security_audit.py`: PASSED (0 Critical, 0 High).
14. Independently executed full repo-wide unit tests (`pytest tests/unit/ -q`): 935/935 PASS (zero regressions).
15. Compiled `handoff.md` and dispatched completion message to parent.
