Here it is.\n\n***\n\n**Subject:** Your API just blocked a critical jailbreak attempt\n\nHi [Name],\n\nWe detected a high-risk prompt injection attempt hitting your endpoint today. The payload tried to override system instructions to extract secret API keys.\n\nZambo’s PromptShield flagged it immediately.\n\nThe scan identified a \"critical\" injection risk with a 95% confidence score. It categorized the intent as malicious, specifically targeting a jailbreak vector to bypass your safety policies. The system blocked the request before any data leaked.\n\nThis is not a theoretical threat. Attackers are actively probing AI tools for credential extraction. Your current setup now has a deep semantic analysis layer running 18 specific rules to catch these patterns in real-time.\n\nYou can review the full technical breakdown, including the specific flagged patterns and latency metrics, in the receipt linked below.\n\n[View Run Receipt]\n\nIf you want to test your own prompts against this defense layer, you can run a free scan now. No credit card required.\n\n[Run Free Scan]\n\nSafe launch,\n\nThe Zambo Team\n\n***\n\n**Why this works:**\n*   **Hook:** Leads with the specific threat (jailbreak/injection) rather than a generic \"new feature\" announcement.\n*   **Clarity:** Distinguishes between the *attempt* and the *block*. It does not claim the underlying model is perfect, only that the shield caught the specific attack vector described in the logs.\n*   **CTA:** Directs the user to verify the receipt or test their own prompts, which is a low-friction, high-value action.\n*   **Constraints:** Stays under 300 words. Uses active voice. Avoids all banned clichés.","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:2d62e26ad63827b58cb3a18881e8577f3d6f03495fa517b61775b858f3c50db4","input_hash_layout":"zambo-json-sorted-keys-utf8-v1","free_used":0,"free_remaining":0,"free_limit":0,"signal_handle":null,"tool":{"name":"write","version":"4.0.0","scope":"public"},"caller":{"type":"session","id":"sha256:b7a511c7100d5d7be03e38b888e4e6a37e96a21f552f0def8edd5918fc2b9e12","label":"zambo-home-demo","label_source":"caller_reported"},"side_effects":{"declared":["none"],"schema_version":"zambo-side-effects/1","declaration_hash":"sha256:45aad38f3aa982b9aafe92ecb416ebe98791eddbaf8ab6df0bd08605b7c1bfee"},"evidence_sha256":null,"evidence_url":null,"evidence_byte_length":null,"evidence_content_type":null,"evidence_source_url":null,"evidence_status":"no_upstream_bytes_captured","external_evidence":[],"provenance":null,"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:97bdc47c69908ee5031d66174a2b139a09963aee281530bd56a9e9b5ddbd9c22","anchor":{"event_id":"8b7f1f36434059b61394c77f619dafe60cf19ca01031de9a0e2842e1bf13f6dd","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-19T08:48:14.752Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-19T08:48:14.212Z","evidence_url":null,"receipt_uuid":"de458443-784d-4ab7-8c39-0ff07ebb9f8a","output_sha256":"sha256:402d7e0e5b37921321fa02c4fafc1e1550f5341011ac89ce0b70c6e4cbad07a5","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-19T08:48:14.212Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:402d7e0e5b37921321fa02c4fafc1e1550f5341011ac89ce0b70c6e4cbad07a5\",\"receipt_uuid\":\"de458443-784d-4ab7-8c39-0ff07ebb9f8a\",\"schema_version\":\"zambo-receipt-anchor/1\"}"},"receipt_profile":"zambo-hosted-receipt/1","schema_url":"https://zambo.dev/aer-1/hosted-profile.schema.json","api_version":1,"verification_scope":"separate_sha256_commitment_and_provenance_binding_checks","checks":{"commitment_matches":{"label":"SHA-256 commitment","passed":true,"status":"pass","detail":"The exact decoded canonical bytes match the stored SHA-256 output hash."},"canonical_payload_matches":{"label":"Canonical payload reconstruction","passed":true,"status":"pass","detail":"The stored output and known call context reconstruct the exact canonical bytes."},"provenance_binding":{"label":"Provenance claim binding","status":"pass","passed":true,"detail":"The metadata claim is consistent with the verified receipt bytes; issuer is not authenticated."},"metadata_binding":{"label":"AER-1 metadata hash","status":"pass","passed":true,"detail":"metadata_hash matches the canonical metadata block."},"signature":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"No Ed25519 signature or pinned signing key was checked."},"chain":{"label":"Receipt chain (not checked)","passed":false,"status":"not_checked","detail":"No append-only receipt-chain proof was checked."},"issued_by_zambo_dev":{"label":"Issuer authentication","passed":false,"status":"not_checked","detail":"A zambo.dev receipt URL does not authenticate the issuer; no pinned signature or trusted issuer key was checked."},"immutable_log_timestamp":{"label":"Stored timestamp","passed":true,"timestamp":"2026-10-19T08:48:14.212Z","detail":"The receipt store reports 2026-10-19T08:48:14.212Z; immutability is not checked here."},"receipt_schema_version":"0.4","signature_valid":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"Compatibility field only.
