Task Objective:
Empirically stress-test and challenge the mathematical EXP curve generated by `server/world/level_progression_curve.py` and stored in `data/game_design_matrix.db`:
1. Write a standalone verification script in your working directory to challenge:
   - Strict monotonicity: `cumulative_exp(L) > cumulative_exp(L-1)` for all 100 levels.
   - Level 1-20 cumulative EXP ratio: must be < 0.1% of lifetime EXP.
   - Level 99->100 delta EXP ratio: must be >= 30% of cumulative 1-98 EXP and 25-35% of lifetime EXP.
   - Death penalty ratios: verify exact values (1-60: 0.0, 61-80: 0.05, 81-89: 0.10, 90-98: 0.15, 99: 0.25, 100: 0.0).
   - Level gap penalty constants: safe_range = 5, penalty_exp = 0.60, benchmark_exp = 25.
2. Run your challenge script and report empirical findings.
3. State your verdict: APPROVE or REQUEST_CHANGES in `handoff.md`. Notify parent via `send_message`.
