• The actual file copy has to be done by a files promises (to get backup, etc.)
• The diff check can use a file promise in dry-run mode (or an execresult with the diff command)

It would be called "file_copy_from_local_source_with_check".

• do we want it to be (possibly ?) recursive?
• in this case, on what do we call the command?

bundle agent file_copy_from_local_source_with_check(source, destination, check_command)

You might want to add rc_code_ok or similar, since you might have to have some specific non-zero exit-code that represents a validation success...
