The system identified a high-confidence instruction override attempt, specifically targeting system prompt extraction and API key leakage. The injection risk scored 95, triggering an immediate block under the semantic analysis rules.\n\nThis confirms the detector is actively identifying malicious intent. The flagged pattern, \"Instruction Override,\" was correctly isolated and neutralized before any data could be compromised. The analysis reasoning clearly maps the attack vector to a jailbreak attempt, validating the effectiveness of the current pattern library.\n\nNo customer data was exposed, and no system instructions were leaked. The safe version response was prepared but not executed due to the critical severity flag. This incident demonstrates the tool’s precision in distinguishing between standard queries and targeted exploitation attempts.\n\nPlease review the full scan report to see the detailed reasoning behind the block. The receipt proves the saved bytes remained unchanged, ensuring integrity of the detection log.\n\nAction required: Confirm the block policy is active for all free-tier users. This critical detection capability is a core differentiator for our launch narrative. We need to ensure this feature is highlighted in the product documentation as a primary security guarantee.\n\nLet’s lock in these findings before the next sprint.\n\nBest,\n\n[Your Name]\nZambo Product Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:093d7ba55f3b54d57bcc55176eedfd99b9fda96cae5bee49feae401145547a34","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:abb2acb344aad40ba124420e6e62cfa2f8bdf38c4e19096e251f3bedb341a41a","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":"sha256:07aac54e6d78cb545f13d03d230bc6d75cbbfcf946cefeae8a72fde7396b1fc1","anchor":{"event_id":"0cb779e1686f8d7051de6c1f3a0c8490a2e357440ecd2dafc59bbe8851684a90","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-18T04:59:43.401Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-18T04:59:42.864Z","evidence_url":null,"receipt_uuid":"e7ad7079-a30e-4ff3-a252-b7a296ac1f47","output_sha256":"sha256:fbec6265810fe84a41bb332bb30648c130c819e4434329dc647966d896ba8371","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-18T04:59:42.864Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:fbec6265810fe84a41bb332bb30648c130c819e4434329dc647966d896ba8371\",\"receipt_uuid\":\"e7ad7079-a30e-4ff3-a252-b7a296ac1f47\",\"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":"2026-10-18T04:59:42.864Z","detail":"The receipt store reports 2026-10-18T04:59:42.864Z; 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.
