A logical region is (the complete logical schema digest, its declaration
ordinal). Names/formats describe that region; no rank, path, stream offset or
device address enters the identity. Byte coordinates preserve opaque state
and permit splitting a serialized value provided restore joins it before use.
Declaration order is semantic and stable across physical placements.
