pub fn hash_binding_at_impl_version(
binding: &Binding,
preparation_impl_version: u32,
) -> StringExpand description
hash_binding under an explicit preparation-implementation version.
The live hash is always PREPARATION_IMPL_VERSION’s; this exists so a
caller can name the hash a prior engine generation keyed its findings on
(the invalidation-by-construction pin, a migration report) without
re-deriving the canonical projection.
