   judged afresh, uses one mesh-sdk form of the writer that observes from its own state: it seeds what it holds from the
   state's keys before it starts, keeps them under its own lock, and its `Observe` answers them, so no part writes that
   adapter (the watchman's copy moves there; the assigner, builder and indexer use it).
+- **A-30** (§383, §686; principle 3) Every module whose writer publishes declares the events it says
+  (`finding-written`, `finding-cleared`, `findings-stated`) in its manifest; none publishes an event it does not declare.
+- **A-31** (A-14, A-22; principles 3 and 7) A module whose old finding keys end in no kind it owns (gitea's package
+  registry, distribution) deletes those old keys once at its start, in its own code, so no stale finding stays; the
+  writer's rule is unchanged.
+- **A-32** (A-29; principle 7) A part that keeps its open findings in memory (artifact-store-tools, mesh-config,
+  distribution, gitea's package registry) uses the held writer of A-29, so a restart neither drops nor rewrites them.
