Task Objective:
Review the Milestone M1 implementation:
1. Review `server/world/level_progression_curve.py`, `server/world/game_design_matrix_schema.py`, `server/world/game_design_matrix_types.py`, `server/world/game_design_matrix_service.py`, `server/world/game_design_matrix_seeder.py`, and `data/game_design_matrix.db`.
2. Verify correctness, architecture, type safety (strict typing, frozen slots dataclasses), and code length compliance (all logic files <= 350-500 lines).
3. Execute verification commands:
   - `python tools/lint/verify_game_design_matrix.py --sync`
   - `pytest tests/unit/test_game_design_matrix.py`
   - `pytest tests/e2e/test_level_progression_e2e.py -k "test_f01 or test_f02 or test_f04"`
   - `python tools/lint/check_code_and_doc_hygiene.py --strict`
4. Document your review in `c:\Projects\FreeExile\.agents\teamwork\reviewer_m1_progression_1\report.md` and `handoff.md`.
5. Clearly state your final verdict: APPROVE or REQUEST_CHANGES. Notify parent via `send_message`.
