BASELINE SURVEY

Evidence movement

Initial observation — no prior comparable baseline linked

Evidence-bearing candidate with no account-specific support identified; do not import geometric-model success.

Why it sits here

The supplied formulation identifies no action, field equations, parameter domain, expansion curve, or perturbation prescription. Accordingly, the exact account cannot be identified with any published model. DESI DR2 supplies a useful observational benchmark: BAO alone is well described by flat LambdaCDM, while joint data show a model- and supernova-sample-dependent preference for evolving dark energy [S91].

Principal uncertainty

This is a bounded documentation-and-evidence assessment, not a proof that the proposal fails. A missing model specification could materially change the assessment; observational tensions do not identify its mechanism.

What would change the view?

Revisit when an explicit derivation, reproducible expansion prediction and bounded comparator/discriminator are available. A fit failure or demonstrated degeneracy would then become assessable.
