No PatrolSafe-authored modifications to these components were identified. Vesoft Authenticode signing changed the signed Sharp PE files, while the underlying unsigned content matched upstream. The binary manifest records the shipped paths, hashes and integration model; the source manifest records exact versions, source identities and archive hashes.

GNU licence texts

Copyright notices and other component-specific licence texts remain within the corresponding source archives and the installed release materials.

Corresponding source and relinking material

The prepared compliance package contains the exact LGPL-related source, the complete source set needed to rebuild the statically combined libvips Windows library, pinned build and patch material, GNU licence texts, manifests, checksums and replacement/relinking instructions. It deliberately excludes proprietary PatrolSafe source code.
