Comparing CSM interaction, central engine, and hybrid models
| Test | CSM | Engine | Hybrid |
|---|---|---|---|
| Rph contracts | FAIL | PASS | PASS |
| T sustained >20kK | FAIL | PASS | PASS |
| LX consistent | FAIL | PASS | PASS |
| Tests Passed | 0/3 | 3/3 | 3/3 |
| Score | 22.84 | 4.73 | 4.67 |
Interaction alone is INSUFFICIENT. A central engine is REQUIRED.
LR test: p = 0.006 (rejects interaction-only at >99% confidence)
