 * Delegates to `isoTimestamp` rather than re-parsing, which is the
 * whole point: an offset-less stamp is read as UTC so every translator
 * (the FUSE attr fold, the runtime bridge, python's twins) answers the
 * same epoch, instead of drifting by the host's UTC offset the way a
 * bare `Date.parse`/`new Date` does. Null (missing or unparseable
 * stamp) is distinct from 0, which is the real answer for
 * 1970-01-01T00:00:00Z; a wire with no validity channel collapses the
 * two at its own boundary.

 * a metadata write visible to a guest and to a mount alike. A backend
 * that reports no mode keeps the default rw-r--r-- / rwxr-xr-x pair;
 * there are no permissions to read on an object store.
 *
 * A link is the exception in both halves: its type bits are S_IFLNK and
 * its permission bits are always 0777, because no POSIX system consults
 * the bits on a symlink. An overlay mode a `chmod -h` wrote is
 * therefore not reported here (ownership is, since `chown -h` does
 * change what `ls -l` shows). Mirrors python's posix_mode.
