 - **A-70** (§572, A-45; the rule that a process answers no call) The builder's tools bundle serves `reserved` and
   `builder_versions`, following the catalog half's view itself as other bundles follow views; the builder's process
   serves no call.
+- **A-73** (§588, §369; principle 7) To publish again, the builder takes each artifact's kind and package name from the
+  catalog entry of the reserved commit, and sends the registry seat's `publish` with the digest and no parts: the
+  holder takes the bytes from the artifact store, addressed by digest (A-50). "Not stored" is the holder's refusal;

+- **A-74** (§700; principle 1, no module names another) The indexer reads the router's `asks` through the seat
+  `operator-channel`: its manifest `uses` that seat, and the bucket is formed from the seat's holder on the seat list
+  and the contract's `StateAsks`, never a module's name in code; the teller's and the node-engine's `messenger_asks`
+  constant goes the same way in their own change.
