 - **A-9** (CT15, §476, §493, §530; principle 8) The `bodies` types are named `TakeInTaken`, `TakeInPending`,
   `TakeInMerge`, `TakeInMember` and `TakeInEntry`, as built in mesh-delivery f38e45fd..1c09de8d.
+- **A-10** (§276, §498; principles 1 and 7, and who may do what is no question) A holder says a seat event through one
+  mesh-sdk call, `Conn.EmitSeat(seat, event, body)`, publishing on `mesh.seat.<seat>.event.<event>`; the grants part
+  grants every holder publish of its held seats' event subjects.
+- **A-11** (GR10; principle 7) A wait's `version` is the holder's own running fingerprint, as the indexer names it.
+- **A-12** (GR10, §276; principle 4) `grants_release` ends the granting wait: the held entries go on, the wait is said
+  ended with `how` `released`, and no `acting-part-late` is raised for it.
+- **A-13** (§461, §439, §383; principle 7) mesh-sdk's writer forms its four subjects itself, in §383's form
+  `mesh.stream.<module>.event.<event>.<node>`, from its module and node, through one function
+  `views.FindingSubjects(module, node)`; a module passes no subjects.
+- **A-14** (§580; principles 7 and 8) A finding that told several findings of one kind on one id apart by a `ref` puts that
+  part into its id (`<id>.<ref>`, each escaped as §73 escapes a name); a kind stays a fixed word of its bundle's list. The
+  key's scope and id and the subject's scope and id are set equal, as before.
