 Validation: review the affected GoDoc together. Reuse the passing shared-capacity
 and cross-view prepared-handle tests; no new behavior or test matrix is needed.
 
+Completion: Engine, WithNamespaces, PrepareExecution, RunPrepared, and the
+prepared-handle GoDoc now distinguish independent constructions from shared
+namespace views. They describe shared clients/capacity and handle ownership,
+with captured selections unchanged by the invoking view. No runtime behavior
+was changed. Reviewed rendered `go doc` output; the existing shared-capacity and
