a C\C++ library and command-line tools for Diff & Patch between binary files or directories(folder); cross-platform; runs fast; create small delta/differential; support large files and limit memory requires when diff & patch.
Reusable binary delta-update engine: apply TRDIFF10/bsdiff+zstd patch chains to a binary, discover chains from a pluggable source (OCI/GHCR or GitHub Releases), and generate+publish patches via a composite GitHub Action. Zero product coupling.
