Module error 

CML engine error type.

The engine reads from a borrowed NodeReader substrate and folds structure over it; its only failure modes are a propagated reader error and a corrupted-on-read invariant violation. Multi-algorithm and epoch errors (unknown algorithm, frozen, malformed timeline) are the polydigest combinator’s concern, not the single-algorithm engine’s.

Enums
