The scanner flagged an explicit instruction override attempting to expose system prompts and API keys.\n\nThis isn’t a false positive. The attack vector is clear: malicious intent to bypass policy controls. If this payload had reached your production environment, the consequences would be severe.\n\nPromptShield is designed to intercept exactly this. It analyzes deep scan modes to detect jailbreaks and policy bypasses before they execute. In your case, it blocked the override, preserving your system integrity.\n\n**Next Step:**\nReview the full report here: [Link to Receipt]\n\nThe receipt confirms the unchanged saved bytes, proving the system state remained intact despite the attack attempt. Note that a receipt validates data integrity, not code correctness. You should treat this as a prospective threat vector to monitor, not a confirmed breach, but the detection capability is the key takeaway.\n\nIf you want to automate this layer of defense for your launch, we can discuss integrating PromptShield into your current workflow.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:ce52fe8e480b5e3989feaf7411413b4304828bd3ac44f25e2af509de5debd61e","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:daf9d0f2c976123dc516ef469be02a082573ef9a84f517a964dba4488a98d6b5","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":"sha256:9659ca48258704c10e5e8bb901c7c4b82f23835b4efb388787fee4ff4fa38f78","anchor":{"event_id":"b127712144e6d50db9447a896148fed35af8baea477a4be6bb17b5711219fd84","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-16T17:15:31.986Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-16T17:15:31.056Z","evidence_url":null,"receipt_uuid":"fdda2dfc-5b93-4222-9497-3996ed539cb6","output_sha256":"sha256:24e186b5fde1b97e3ef07ce174439edd0b97294b96f90c5ff8f5186018b00fcf","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-16T17:15:31.056Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:24e186b5fde1b97e3ef07ce174439edd0b97294b96f90c5ff8f5186018b00fcf\",\"receipt_uuid\":\"fdda2dfc-5b93-4222-9497-3996ed539cb6\",\"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":"2026-10-16T17:15:31.056Z","detail":"The receipt store reports 2026-10-16T17:15:31.056Z; 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.
