The version a sidecar carrying a IdentityMapSidecar.keyProperty is
written under (issue #4955). A version-1 consumer ignores unknown fields and
applies the entries under its own GlobalId scheme; for a map whose keys were
taken under an authored property that is precisely the silent misapplication
the key-scheme check exists to prevent, so such a map is stamped a version the
old consumer refuses outright. A map with no keyProperty stays version 1,
byte-identical to before.
