+> **Progressive insight — 2026-10-01.** The decision stands; these are the facts of its building.
+
+- The controller's half: mesh-controller 188 — the membership, its subject, the assignments stream
+  read directly, a module's account granted its own membership and nothing else of the stream, a
+  membership published after each push.
+- The runtime's half: mesh-tools 23 — the one address derived, the membership read and followed,
+  exactly the issued subjects served and re-served, the derived shape with a log line until one is
+  issued, a seat's verbs implemented under the seat's name and never listed as the module's, the
+  listing carrying subjects and the console composing none. A claim may now name the verbs it
+  serves for its seat (mesh-controller 186), so a holder's own tools need not be the seat's.
+- What the first roll-out taught: the controller's own grant did not name the assignments it issues,
+  so the first memberships were refused by the server and every runtime kept the derived shape —
+  which is exactly the fallback this record asked for, and exactly why nobody noticed
+  ([issue 183](../04-ISSUES/183-the-controller-could-not-publish-the-memberships-it-issued/00-report.md)).
+  The SDK's `invokeTool` still composes a subject; it reaches a membership through the runtime's
+  broker, which does, so the caller-side rule is met there and not yet in the SDK's own words.
