libfsverity-dev 1.4-1~exp1build1 (amd64 binary) in ubuntu jammy

 fs-verity is a Linux kernel feature that does transparent on-demand
 integrity/authenticity verification of the contents of read-only files,
 using a hidden Merkle tree (hash tree) associated with the file. The
 mechanism is similar to dm-verity, but implemented at the file level
 rather than at the block device level.
 .
 This package contains the libfsverity development libraries and header files.
