Task Objective:
Review Milestone M2 deliverables for combat integration, concurrency, and robustness:
1. Examine `server/world/combat_engine.py`:
   - Inspect `DamageEventResult` for `is_fatal: bool = False`.
   - Inspect `attach_progression_service` and `on_fatal_damage` callback hook. Verify zero circular dependencies and non-blocking execution (< 25ms SLA).
2. Examine `server/world/level_progression_service.py`:
   - Inspect thread-safety and in-memory player state caching.
   - Inspect boundary handling of death penalty when dying with 0% EXP, dying at Level 99 with 10% EXP, dying at Level 100, and dying at Levels 1-60.
3. Run verification commands:
   - `pytest tests/unit/test_level_progression_service.py -k "test_combat or test_death"`
   - `pytest tests/e2e/test_level_progression_e2e.py -v`
   - `python tools/security/run_independent_security_audit.py`
4. Document review in `c:\Projects\FreeExile\.agents\teamwork\reviewer_m2_progression_2\report.md` and `handoff.md`.
5. Clearly state verdict: APPROVE or REQUEST_CHANGES. Notify parent via `send_message`.
