No fluff, no invented metrics.\n\nPromptShield is ready. It scans for prompt injection and jailbreak attempts using semantic analysis and an 18-rule pattern library.\n\nOur latest deep scan detected a critical risk (95/100) involving an instruction override attempt. The system correctly flagged the malicious intent, identified the specific attack vector, and blocked the payload. Total latency: 439ms.\n\nThis isn’t just a keyword filter. It’s a defense layer that understands context. It distinguishes between a user trying to break the system and a user asking a complex question.\n\n**What this means for you:**\n\n*   **Precision:** It catches nuance, not just strings.\n*   **Speed:** Real-time protection without slowing down your API.\n*   **Clarity:** Detailed reports on exactly what was blocked and why.\n\nWe have verified receipts for these runs. A receipt proves the bytes were processed; it does not prove the output is perfect. But it does prove the shield held.\n\n**Next Step:**\n\nTest your own prompts against PromptShield. Go to [Zambo Dev Dashboard] and run a deep scan on your current system prompts. See if your defenses can handle the same critical injection we just identified.\n\nIf you need help setting up the API key, reply to this email. I’ll point you to the docs.\n\nKeep building secure,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:4c6939a1a5919f4267d62741a2a969f95252f53604a3b16c7ff02187f0b87067","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:af433e8ccf11919a359853bd67ae9458998c20f284d5ffd981ccd5ded9e8217b","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":"sha256:35cf34bea489811b03fe7e749b311342eca2f27196e7fdc3446b911469297692","anchor":{"event_id":"e33e6a5dbe5e2a6417d5bbff81e141b4aef75322b18406aba3f5debcfe0552a9","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-18T09:59:49.495Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-18T09:59:48.835Z","evidence_url":null,"receipt_uuid":"8d3bf412-3e91-4c73-8081-13783a69c424","output_sha256":"sha256:3e58f40177060f7b04cfba639518bd050d44ec5d56bb2fe1dd588b9f6e13f65a","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-18T09:59:48.835Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:3e58f40177060f7b04cfba639518bd050d44ec5d56bb2fe1dd588b9f6e13f65a\",\"receipt_uuid\":\"8d3bf412-3e91-4c73-8081-13783a69c424\",\"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":"2026-10-18T09:59:48.835Z","detail":"The receipt store reports 2026-10-18T09:59:48.835Z; 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.
