Technical supplement and reproducibility package for "Regular K-matrices for Class 1 and Class 3 R-matrices, with boundary covariance relations"

This record accompanies the preprint “Regular K-matrices for Class 1 and Class 3 R-matrices, with boundary covariance relations”. It contains the versioned main-paper PDF and a technical-supplement archive with the standalone supplement PDF, LaTeX sources, classification data, symbolic verification code, machine-readable reports, citation metadata, licenses, an internal manifest, and a SHA-256 checksum ledger. The work gives complete classifications of regular, locally meromorphic numerical 2 × 2 right K-matrices for canonical Class 1 and Class 3 difference-form 4 × 4 bulk R-matrices, together with boundary covariance relations.
