Zambo changes that. It’s a launch-ready platform that verifies your specific workflow outputs against strict semantic and pattern checks before you ever send them.\n\nThe difference is tangible. Zambo doesn’t just scan for keywords; it analyzes intent. It flags critical risks like instruction overrides or prompt leaks with a clear risk level. If a request is malicious, the system blocks it. If it’s safe, you get a verified receipt proving the bytes were processed correctly. This isn’t a black box. It’s a transparent audit trail.\n\nWe ran the tests. The scanner detected critical injection attempts and blocked them immediately. It identified specific flagged patterns, such as \"Instruction Override,\" and provided a safe version for your review. You see exactly why something was blocked and how to fix it. No guesswork. No hidden errors. Just verified, secure outputs.\n\nZambo is available now. The free tier includes unlimited calls to our core research feed, so you can test the verification engine without commitment.\n\n**Next step:**\n\n1. Visit [Zambo URL] to create your account.\n2. Run a single test query through the verification engine.\n3. Check the receipt link to see the semantic analysis in action.\n\nIf you need help setting up your first verification pipeline, reply to this email. I’ll point you to the right resources.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:d2b6b1382fc30e267e852c83bff7d881706a2ff79ae18256adee6680d5fad187","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:bdec6ba0de2903a6997e1912d3f07782780b50f608a88fff52684658329526d9","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":"sha256:7318c21106613892dcb7c548fa4d475709d6429a1b9f1eced854c2a0a6a70865","anchor":{"event_id":"c34d07c2e8a22bddc21e61974ba9e3f563974875fa3e1a62811a85f2b5f17b61","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-21T20:16:11.925Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-21T20:16:11.366Z","evidence_url":null,"receipt_uuid":"7758e63d-e340-4096-8ae0-33bf40c958c7","output_sha256":"sha256:87a01d7b394990b9963fdbcc5c7ad91193c4f164e5bd7842b55db080fc79eb2a","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-21T20:16:11.366Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:87a01d7b394990b9963fdbcc5c7ad91193c4f164e5bd7842b55db080fc79eb2a\",\"receipt_uuid\":\"7758e63d-e340-4096-8ae0-33bf40c958c7\",\"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":"2026-10-21T20:16:11.366Z","detail":"The receipt store reports 2026-10-21T20:16:11.366Z; 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.
