TimeLoweringProof

eqiora::time

Struct TimeLoweringProof 

pub struct TimeLoweringProof { /* private fields */ }
Description

Backend-neutral witness for canonical Relation → first-order lowering.

The witness records facts proven from Operator IR, not solver output. Its constructor derives the admitted equation class. A full monomial Jacobian normalizes to an explicit ODE; every other non-zero-rank constant matrix remains a full or rank-deficient mass matrix.
