Two-regime pattern: pre-Flood constant, post-Flood exponential decay with floor. Six competing models were tested via AIC (linear, power law, step function, pure exponential, exponential+floor, logistic). Exponential+floor wins decisively (ΔAIC = 5.3 over pure exponential).
| Model | Form | Result |
|---|---|---|
| Linear | y = mx + b | Rejected |
| Power Law | y = atb | Rejected |
| Step Function | Discrete jump | Rejected |
| Pure Exponential | y = Ae-t/τ | ΔAIC = 5.3 |
| Exponential + Floor | y = Ae-t/τ + Lfloor | BEST FIT |
| Logistic | Sigmoid curve | Rejected |

The asymptotic floor Lfloor is not a free parameter chosen for convenience. It converges from four independent sources spanning 3,400 years — from Moses to modern actuarial science.
These four tests are the gatekeepers between Correspondence and Isomorphism. ALL FOUR must pass for Level 3 classification.
This claim carries its own kill conditions. If any of the following are demonstrated, the isomorphism is demoted or destroyed:
As long as G > 0, there is a nonzero equilibrium. Coherence can't hit zero because grace doesn't quit.
