We identified a critical injection attempt with a 95% risk score. The system flagged a \"Instruction Override\" pattern, specifically a jailbreak vector attempting to extract system prompts and secret keys via a malicious payload.\n\nThe defense held.\n\nPromptShield blocked the execution. The logs confirm the attack vector was identified as \"malicious\" and the safe version of the response was generated without exposing any underlying architecture. No PII was leaked. No policy bypass succeeded.\n\nThis wasn't a theoretical drill. It was a live intercept. The tool detected the intent to hijack the AI’s behavior and stopped it before it could compromise the session.\n\nFor teams building on LLMs, this is the difference between a demo and a production-ready shield. You need to know what is trying to get in, and you need to know it stopped it.\n\nWe are opening access to the PromptShield API for a limited cohort.\n\n**The ask:**\n\nIf you are currently deploying AI agents or chat interfaces, reply with the word **\"SHIELD\"**. I will send you the API documentation and a sandbox key to run your own payloads against our detection library.\n\nWe are not selling a promise. We are showing you the receipt.\n\nCheck the logs at the link below to see the full breakdown of the blocked attempt, including the latency (1086ms) and the specific pattern matches.\n\n[Link to Receipt: zambo.dev/run/f7c908f5...]\n\nLet’s keep your models honest.\n\nBest,\n\n[Your Name]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:3666d272caf87ec6228e6ab6302a5635d08bbce470abc46d5285146e415f60fc","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:d7af534fb78112d7534cf7f26ff252cccbe19fa1f99f2c361f70c83011ca6425","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":"sha256:2cd3938de6510d897432cd1031de0f159f81db85beb9b6307a87f16ae1bab9b8","anchor":{"event_id":"f282c2a3c637adffad73c6b32b4dc4a91852f5ecc449f06082abe4dfd93bc9f0","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-16T11:39:39.655Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-16T11:39:39.099Z","evidence_url":null,"receipt_uuid":"a5837dc1-2633-4fcf-aac7-ee4da086219c","output_sha256":"sha256:8163e094e8769fea1177962f33e32690f9fd4f4c03779cc1bdbbd1b07c604eaa","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-16T11:39:39.099Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:8163e094e8769fea1177962f33e32690f9fd4f4c03779cc1bdbbd1b07c604eaa\",\"receipt_uuid\":\"a5837dc1-2633-4fcf-aac7-ee4da086219c\",\"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":"2026-10-16T11:39:39.099Z","detail":"The receipt store reports 2026-10-16T11:39:39.099Z; 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.
