## Investigation State
- **Explored paths**:
  - `server/world/level_progression_curve.py` (Line 68-71: Segment 7 delta calculation)
  - `tests/e2e/test_level_progression_e2e.py` (Line 52-55 oracle, Line 135-142 assertion)
  - `server/world/game_design_matrix_seeder.py` (Line 242-265 seeding logic)
  - `server/world/game_design_matrix_service.py` (Line 80-96 seed table management)
  - `tools/lint/verify_game_design_matrix.py` (Sync and validation gate)
  - `.agents/teamwork/challenger_m1_progression_1/challenge_exp_curve.py` (Challenger harness)
  - `data/game_design_matrix.db` (`progression_benchmarks` table)
- **Key findings**:
  - Factor $0.33$ produced $\text{Ratio}_{\text{lifetime}} = \frac{0.33}{1.33} = 24.812030\% < 25.0\%$, triggering Challenger Gate failure.
  - Admissible parameter window: $f \in [1/3, 7/13] \approx [0.333333, 0.538462]$.
  - Factor $0.35$ produces exact values: $sum\_1\_98 = 17,989,242,456$, $deltas[99] = 6,296,234,859$, $total\_lifetime = 24,285,477,315$.
  - Tỷ số so với 1-98: $35.000000\% \ge 30\%$.
  - Tỷ số so với Lifetime: $25.925926\% \in [25.0\%, 35.0\%]$.
  - Strict monotonicity preserved across all 100 levels ($target\_exp(100) > target\_exp(99)$).
  - Delta strictly increasing from Level 1 to 99 ($\Delta_{99} = 6,296,234,859 > \Delta_{98} = 3,330,652,650$).
  - Tutorial budget preserved ($sum\_1\_20 = 3,248,870 = 0.013378\% \ll 0.1\%$).
- **Unexplored areas**: None. Complete mathematical and systemic analysis finalized.

## Key Decisions Made
- Confirmed factor $0.35$ as the optimal canonical value.
- Formulated exact drop-in code snippets for Worker M1 across `level_progression_curve.py` and `test_level_progression_e2e.py`.
- Documented full verification workflow for Challenger M1 and Orchestrator.
