+Completion: the facade now copies mutable values directly into the public report,
+without first cloning an intermediate domain report. Provider parameters retain
+the existing JSON-value copy/error handling and pass through the shared target
+projection without another copy; credentials remain excluded. Domain cloning
+continues to serve its separate internal ownership boundary. Focused conversion
+coverage protects retained source values, independently converted results, nested
+maps/slices, optional facts/timings, attempts, credential exclusion, and copy errors.
+Existing public and domain ownership tests remain unchanged. Validation passed
+with `GOWORK=off`: focused ownership tests, `go test -race ./...`, `go vet ./...`,
+the three offline consumer examples, and `git diff --check`.
