The attack vector was a jailbreak trying to bypass safety policies.\n\nPromptShield caught it.\n\nHere is the breakdown:\n*   **Status:** Blocked.\n*   **Mode:** Deep semantic analysis.\n*   **Flagged Pattern:** Instruction Override (Severity: Critical).\n*   **Intent:** Malicious.\n*   **Latency:** 1,262ms.\n\nThe receipt confirms the saved bytes are unchanged, proving the integrity of your original data.
