 No policy was retuned after seeing these scores. Production ANN/hybrid evidence,

 source-specific confidence remain open. The experimental media rating is unchanged.

+Recorded manifests use their exact observed bytes. The initial Git commits
+normalized CRLF JSON while the local run retained CRLF; commit `512ec4e` preserves
