Constant RENDERED_MANIFEST_SCHEMA 

pub const RENDERED_MANIFEST_SCHEMA: &str = "pgroles.manifest.v1";

Schema identifier for the YAML body emitted by render-bundle. Bumped only on incompatible changes to the PolicyManifest serialization shape. Recorded in the header so --check failures after a pgroles upgrade can be diagnosed as “schema bump → re-render required” rather than mystery drift, and so consumers parsing the rendered file can detect mismatches.
