Task Objective:
Review Milestone M2 deliverables for correctness, architecture, and type safety:
1. Examine:
   - `server/world/level_progression_types.py`
   - `server/world/level_progression_service.py`
   - `server/world/combat_engine.py`
   - `tests/unit/test_level_progression_service.py`
   - `tests/e2e/test_level_progression_e2e.py`
2. Verify:
   - Immutable models with `@dataclass(slots=True, frozen=True)` and property aliases.
   - Strict typing (mypy clean with 0 errors).
   - Code length constraints: all logic files <= 350-500 lines, functions <= 50 lines.
   - Level gap penalty: Delta <= 5 (1.0), Delta > 5 (exp(-0.60 * (Delta - 5))), Delta >= 10 (<= 0.05).
   - Level cap at 100: zero overflow past Level 100 cumulative EXP.
   - Tiered death penalty: 1-60: 0.0, 61-80: 0.05, 81-89: 0.10, 90-98: 0.15, 99: 0.25, 100: 0.0.
   - Safe floor at 0%: never de-levels (`de_leveled = False`).
3. Run verification commands:
   - `pytest tests/unit/test_level_progression_service.py -v`
   - `pytest tests/e2e/test_level_progression_e2e.py -k "test_f03 or test_f04 or test_f05"`
   - `python -m mypy --explicit-package-bases --follow-imports=silent server/world/level_progression_types.py server/world/level_progression_service.py server/world/combat_engine.py tests/unit/test_level_progression_service.py`
   - `python tools/lint/check_code_and_doc_hygiene.py --strict`
4. Document review in `c:\Projects\FreeExile\.agents\teamwork\reviewer_m2_progression_1\report.md` and `handoff.md`.
5. Clearly state verdict: APPROVE or REQUEST_CHANGES. Notify parent via `send_message`.
