 The regular `Security Audit` workflow reuses the fingerprinted toolbox image
 when the Docker daemon is persistent, which is the normal case for the
-self-hosted Gitea runner using the host Docker socket. The separate
+self-hosted Gitea runner using the host Docker socket. Trusted push, schedule,
+and manual runs scan all registered repositories; authenticated SSH is used
+only for the private website repository. Pull-request audit runs stay disabled
+while the audit runner exposes its host Docker socket: PR-controlled audit code
+must run on a disposable or rootless runner without host-socket access. The
+separate
 `Security Audit Toolbox Update` workflow runs weekly with
 `SECURITY_AUDIT_UPDATE=1`; it pulls current base images and re-resolves the
 allowed tool version ranges into a refreshed local image.
