There was a problem hiding this comment.
This contradicts the new pad_to_align_spec: its postcondition explicitly proves R % A = 0 and that R is no greater than every aligned q ≥ S (zerocopy/src/layout.rs lines 531–532), which establish alignment and minimality. Describing these properties as unproved misstates the verification scope and may lead future maintainers to weaken or duplicate the checked obligations; clarify that the caller theorem inherits both guarantees from padding_lt_alignment.
