This is it.\n\nZambo is now live. It executes complex workflows—research, signal detection, and semantic analysis—and returns verifiable receipts for every action. No black boxes. No \"trust us.\" Just hard data on what ran, what it found, and what it didn’t.\n\nThe core value is transparency. When Zambo runs a lead signal search, it doesn’t guess. If it finds no source-backed leads, it says so explicitly and provides a receipt proving the query executed with zero results. We do not invent customers. We do not hallucinate success. We provide the artifacts you need to audit the work.\n\nFor example, a recent scan for web design prospects in Austin, TX, returned zero leads. The system executed the trade, checked the quota, and confirmed no results. The receipt remains available for your review. That honesty is the product.\n\nWe also scanned a potential prompt injection attack. The system flagged it as critical, identified the specific override patterns, and blocked the malicious intent before any data leaked. It didn’t just \"handle\" the error; it dissected the threat vector and documented the defense.\n\nThis is how you build trust in an AI era. You don’t just ask for confidence. You demand evidence.\n\n**Next Step:**\nReview the attached receipts to verify the execution logs. If the data holds up to your scrutiny, let’s talk about integrating Zambo into your current operations.\n\nReply with “Interested” to schedule a 15-minute technical demo.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:2813f4c0b4694365edc5729566b69f584f3e8229f4c152636bb6d128a3bd48b4","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:b63d9c9264c7dd990315229982d849e916d5ce89bb1d6748fd9c0a527b36f699","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:e89274700cd910d96146a7160b2d7b01941113e2dbb783213d329b4cb5b55a1c","anchor":{"event_id":"966ac0c0a6dfbfd2d3d01088bf74096009643fdf20b90f2d8cbfa56effc315fe","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-21T16:16:28.249Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-21T16:16:25.863Z","evidence_url":null,"receipt_uuid":"0fd61f23-acb8-4d0d-8c70-7a9ceac7afbc","output_sha256":"sha256:5bfeb249657681529055858fc77f66c3bf2f4493374b89ad1ce720fd5413f39c","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-21T16:16:25.863Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:5bfeb249657681529055858fc77f66c3bf2f4493374b89ad1ce720fd5413f39c\",\"receipt_uuid\":\"0fd61f23-acb8-4d0d-8c70-7a9ceac7afbc\",\"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":"2026-10-21T16:16:25.863Z","detail":"The receipt store reports 2026-10-21T16:16:25.863Z; 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.
