Zambo Launch: Zero Results, Full Transparency**\n\nWe just ran our first live lead generation test for a web design prospect in Austin.\n\nThe result? Zero hits.\n\nThis isn’t a failure. It’s a feature. Our `leadsignal` tool returned `no_results` because we refuse to hallucinate leads. We don’t guess. We don’t inflate numbers. We only return source-backed data. In this specific market window, there were no verified, public sources matching the criteria.\n\nThat’s why you should care about the receipt: [https://zambo.dev/run/87b3dc2e-8054-4f22-86f6-df73e0b72e38](https://zambo.dev/run/87b3dc2e-8054-4f22-86f6-df73e0b72e38)\n\nThis link proves exactly what happened. It shows the query, the tool used, the quota status, and the empty result set. No spin. No \"potential\" customers disguised as sales. Just raw, auditable output.\n\nMost AI tools promise magic. They give you plausible-sounding fiction. Zambo gives you the truth, even when the truth is \"no leads right now.\" That reliability is the core of our launch. We are building a stack where every claim has a provenance certificate. If a tool says it found a lead, you can click the receipt and verify the source. If it found nothing, you see exactly why.\n\nWe are currently in a deep-scan phase. Our semantic analysis flagged a critical injection risk in a test input, correctly blocking an attempt to override system instructions. That’s the same engine protecting your data integrity.\n\n**What we need from you:**\n\nClick the receipt link above. Verify the data. Tell us if the transparency resonates.\n\nWe are not selling you a miracle. We are selling you a provable workflow.\n\n[https://zambo.dev/run/87b3dc2e-8054-4f22-86f6-df73e0b72e38](https://zambo.dev/run/87b3dc2e-8054-4f22-86f6-df73e0b72e38)\n\nBest,\n\nThe Zambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:b30781a05551dacc2feb3546caa9c488fceb019d54239d815cc1dc2f6c6216b5","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":"sha256:65dee7d571eaade2c5808fe7382a3345ba7f348270727867d6e48c464d67f364","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:f503a12b01bdcc38ffe410f180639cfdc34242dc95c56c0c2b7d730f40281aae","anchor":{"event_id":"8c213a2d0988c378f41159494eddfafe9df3a4e5b269ca90088fdce931b08126","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-30T13:50:46.523Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-30T13:50:40.493Z","evidence_url":null,"receipt_uuid":"3729702b-55ab-4a31-82d9-8b145dbd5e43","output_sha256":"sha256:ae0848f85c1f42d503f05cd50c6a250e1ada7a69f8352ef8a17ef909f79c1071","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-30T13:50:40.493Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:ae0848f85c1f42d503f05cd50c6a250e1ada7a69f8352ef8a17ef909f79c1071\",\"receipt_uuid\":\"3729702b-55ab-4a31-82d9-8b145dbd5e43\",\"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":"2026-10-30T13:50:40.493Z","detail":"The receipt store reports 2026-10-30T13:50:40.493Z; 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.
