ADR 0625 §1-§3 (accepted 12:45): the seat set stays the root Go module's package; each seat defined whole is a Go
module of its own, since the fingerprint counts a Go module's go.mod and go.sum, so a change of one seat moves only
its importers. A seat's module imports nothing: the registry part's types are written into each registry seat whole,
so no seat module requires a sibling's version.

Each package carries the contracts marker generated-from naming the module's root, where seats/, parts/ and format/
are. No merge-check.sh: the checker runs every repository's tests by Go's convention (ADR 0529).
