+- Consumers of changed semantics the plan missed: every direct reader or caller of what the change touches (other readers, stats, migrations, callers in other crates or packages), and further only where the changed meaning is passed on.
 - Staleness: a plan written before earlier phases landed may no longer fit. Read the previous phase's run log and review only when something is off.

+- Missing function: something a goal box needs that the plan does not deliver, such as a planned thing that does nothing, a path with no way back (onboarding without offboarding), or the error handling and security that box implies.
+- A function no box needs is not missing: propose it under the open decisions with a one-line reason instead of adding it to the build plan.
