Model Comparison Laboratory v0.3
Run a conventional baseline beside the unchanged MEFI core, preserve both raw outputs, import real observations, and calculate comparison metrics only after the simulations finish. The page does not declare a winner without comparable evidence.
Framework contrast · what this page is actually demonstrating
The conventional side is allowed to use the equations appropriate to its domain. The MEFI side is not. MEFI must retain the same core in every case. This section describes structural differences only; benchmark performance is reported separately and only when comparable observations are loaded.

kr compression · kc expansion · r relationship · nonzero signed ΔQ · fUFR(t). FMEFI is the current snapshot.
Displayed factors and domain assumptions are explicit in the conventional ledger.
The substrate and active relationship change; the governing core does not.

same core every relationshipMEFI continuous reevaluation · snapshot history & stability ranges
Every row is another evaluation of the exact same core. The page never invents a second dynamical law. You may import a real MEFI relationship history, or generate a clearly labeled transparent test trajectory by interpolating between visible anchor states.

Side-by-side result ledger
Metrics summarize completed outputs; they never generate MEFI state. Raw mode requires comparable target units. Shape mode uses post-simulation min–max normalization and is labeled as shape-only.

Conventional configuration ledger
MEFI configuration ledger
- One governing core formula across every module.
- k_r remains compression; k_c remains expansion.
- r is active relationship / separation.
- ΔQ is always nonzero signed difference.
- f_UFR(t) is current UFR occupation.
- F_MEFI is a snapshot, not a permanent state.
