Task Objective:
Empirically stress-test and challenge `server/world/level_progression_service.py`:
1. Write a standalone empirical challenge harness `challenge_level_progression.py` in your working directory to challenge:
   - Level Gap Exponential Decay: test Delta from 0 to 50. Verify Delta <= 5 is exactly 1.0, Delta > 5 strictly follows exp(-0.60 * (Delta - 5)), and Delta >= 10 yields <= 0.05.
   - Level Transition & Cap: simulate player gaining 1 EXP, 1,000 EXP, 10,000,000 EXP. Test multi-level transitions (e.g. Level 1 jumps to Level 5 if massive EXP given). Test Level 99 to 100 transition. Test kills at Level 100 awarding exactly 0 EXP.
   - Tiered Death Penalty Matrix: simulate player deaths across all 100 levels. Verify exact penalty percentages (1-60: 0%, 61-80: 5%, 81-89: 10%, 90-98: 15%, 99: 25%, 100: 0%).
   - Safe Floor Invariant: test dying at 0% EXP (loses 0, remains at same level), dying at 5% EXP when penalty is 25% (loses only 5%, clamped to 0%, de_leveled = False).
   - Polymorphic parameter calls: call `award_monster_exp` with positional args `(player_id, monster_level, zone_level, base_exp)` and keyword args.
2. Run your challenge script and report empirical output.
3. State verdict: APPROVE or REQUEST_CHANGES in `handoff.md`. Notify parent via `send_message`.
