+- **A-22** (§686, §689, A-14; principle 7) As built in mesh-catalog 9677f200 and b78e90c0: a pending finding's bound is the
+  module's own check interval; a field the contract's `Finding` lacks (`resolved`) is dropped; an id is escaped as a
+  name, and a `ref` goes into the id only where two findings of one kind share an id; old keys are cleared by the
+  writer's first statement. mesh-sdk keeps no old `views.Finding` or `FindingWriter` beside the generic writer.
