get_canonical_mode_rows(self, signature, ordering): 

Canonical sparse row bytes, shared across checked-position maps.

The bounded cache holds only distinct mode-tuple reorderings. Thus interning equivalent predicates does not reconstruct the full resonance-mode x projection-map Cartesian product for every plan.
