No membership is published since release 6 (issue 1945 notes 42, 47), so a seat-holding module placed now cannot
serve its seat or pull asks (mesh-build-go on ace, 2026-10-25). The operator decided at 22:31 that the grants part
publishes them from the first milestone: its principal, module mesh-grants, may publish mesh.assignment.*.* and no
stream definition. The SDK's copy of this composer gets the same line, so the two stay byte-equal.
Research 072 (the controller, NATS-native): this moves the memberships of its Bus row to the grants part.
