Degeneracy Graph Determinant: Recurrence

Abstract

Occupied-degree reindexing turns the arbitrary-depth source square into a block-triangular pruning recurrence.

The recurrence owner supplies the canonical bottom and column equivalences, the actual pruning matrix, its low-block and triangular identities, and the signed determinant recurrence. No determinant sign is hidden in an ordering convention: fiber orientation and pruning permutation signs are explicit declarations.
