Detailed Description

Mutable builder used to assemble an immutable Matrix one column (or one term) at a time.

Note

AI-generated documentation. Verify against the source before relying on it.

Held while the matrix is in flux: tracks the target / source FreeModules, the in-progress column vectors in entries, a shared degree shift deg, and the cols_frozen flag that locks the source free module once the caller commits to a column count. to_matrix() (declared further down) snapshots the current state into a fresh Matrix*, after which the MatrixConstructor can be discarded or refilled.
