[recmo]

On 2026-07-13 in 61744fa “Merge pull request #470 from worldfnd/feat/base-field-witness-commit”:

run the challenge-bearing fixtures on the base-leaf field once a
base-field LogUp construction is available.

//! Base-compatible fixtures run on the canonical base-leaf `GoldilocksField`.
//! The challenge-bearing fixtures (LogUp, multi-challenge) place extension
//! challenge values in the witness, so they run on `GoldilocksEfField`, whose
//! base and extension fields coincide.
//!
//! TODO: run the challenge-bearing fixtures on the base-leaf field once a
//! base-field LogUp construction is available.
