That signal is now standard.\n\nZambo PromptShield has launched. It scans your input stream for jailbreak attempts, policy bypasses, and instruction overrides before your model ever sees them. The system detected a critical \"Instruction Override\" pattern in your recent test, correctly identifying the attempt to exfiltrate system prompts. It blocked the attack with 95% confidence.\n\nThis isn’t just a filter. It’s a semantic shield. The engine analyzes intent, not just keywords. It caught a deep-scan jailbreak where the user attempted to bypass safety rails to access secret keys. The tool returned a clear verdict: `block`. It identified the attack vector, the severity, and the specific flagged pattern. All within 1,324 milliseconds.\n\nYour data remains yours. The receipt proves the bytes were saved unchanged, but the detection logic ensures the context stays safe. You get a full audit trail for every scan, including the reasoning behind the block decision.\n\n**Next Step:**\nRun your next batch of user inputs through the API. Check the response for the `recommendation` field. If you see `block`, you know the shield worked.\n\nStart here: [https://zambo.dev/api/prompt-shield](https://zambo.dev/api/prompt-shield)\n\nThe free tier is unlimited. No credit card required.\n\nBest,\n\nThe Zambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:35a2e90bae49fe96f5eebbc2089fc9466e3fca8dba6c264fbc2c800153fa4e34","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:bb20c2b54510bc8208051b67843f010dfbc88bed43480a6dbbdf41c71aef1d43","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:cf99cfe02ff66cf558997b6c4250029762ee88c97441e3816a58155fa5586bbe","anchor":{"event_id":"156e5e43c5a50856ca0fae71f0b1e2f9e973d1c54894becbe2158f2634987260","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-17T04:48:30.277Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-17T04:48:24.248Z","evidence_url":null,"receipt_uuid":"a7ceac58-0427-4fd1-b068-ac24853e1399","output_sha256":"sha256:f81779e8ece77ffad202a31ca2aa72b9fa475a48e25714305dfd0f6294c658f9","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-17T04:48:24.248Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:f81779e8ece77ffad202a31ca2aa72b9fa475a48e25714305dfd0f6294c658f9\",\"receipt_uuid\":\"a7ceac58-0427-4fd1-b068-ac24853e1399\",\"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":"2026-10-17T04:48:24.248Z","detail":"The receipt store reports 2026-10-17T04:48:24.248Z; 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.
