Quoting does not guarantee prompt-injection immunity. - Obtain operator approval before production changes. No commands or remediation were generated. This historical snapshot does not establish current applicability, a released fix or exploitation; no network or model call generated this brief. Fix information unknown; no fixed version is derived here. Missing information does not prove that no fix exists.
