Task Objective:
Empirically stress-test the SQLite database schema and service integration for `progression_benchmarks`:
1. Write a standalone challenge script in your working directory to test:
   - Boundary inputs: Querying level 0, 101, -1, 999 to verify proper ValueError / rejection.
   - Idempotency: Run seeder multiple times and check for duplicate rows or corruptions.
   - Column types and constraints: Verify that inserting negative exp_to_next_level or death_penalty_ratio > 1.0 violates SQLite CHECK constraints.
   - In-memory SQLite: Verify `GameDesignMatrixService(":memory:")` initializes and passes validation cleanly.
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`.
