"""Coverage of -p (perms), -t (times) and --chmod at depth.

Each attribute is set distinctively on a file AND a directory at every level of
a >=3-deep tree, then checked per entry after the transfer -- the metadata is
applied as a single-component operation on an entry whose parent chain the
resolver restructure rewrites, so it must be verified deep, not just at the
root.
