Zambo is live (and it found zero leads)\n\nHi [Name],\n\nZambo just launched. I’m not here to tell you it’s a \"game-changer\" or ask for your time. I’m here to show you exactly what it does when you point it at a real, messy task.\n\nI ran a specific test: find public, source-backed prospective customers for an AI tools product launch. No outreach. No invented contacts. Just research.\n\nHere is the unvarnished result:\n\n1.  **The Input:** A request to identify leads in Austin, TX for web design, with a strict instruction to only use verified sources.\n2.  **The Output:** `no_leads`.\n3.  **The Proof:** The system executed the search, checked the provider, and returned zero results. It did not hallucinate a contact to please me. It did not try to bypass the \"no leads\" state. It simply reported the truth: there are no verified leads for that specific query right now.\n\nThis is the core value of Zambo. Most AI tools will make up an answer to keep you happy. Zambo refuses to. It distinguishes between a completed action and a correct answer. A receipt proves the bytes were saved; it does not prove the data is right. Zambo treats this distinction as non-negotiable.\n\nI didn’t send any emails. I didn’t invent any names. I just got a clear, factual answer about the state of the market for that specific niche.\n\nIf you want to see this for yourself, here is the direct link to the execution receipt. It shows the full chain of logic, the tool usage, and the final, accurate result:\n\n[View Execution Receipt](https://zambo.dev/run/6e6e3388-89c9-4b9f-9c83-f919e119d4fb)\n\n**Next Step:**\n\nIf you have a research task that requires absolute accuracy and zero fluff, try Zambo.\n\nUse Zambo to hand this over to [Client Name].\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:c6cd36da97d747b76413c45243c14d06a5defb79406be5d5bd7dec223a08d0c1","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":"sha256:0f8e753385eb6a23e674c5a0fdfe102adcf37b3d5c89d4d92baf297b852db803","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:c0634ac4d3054730d687290854bc484d4a6399c210e8fea287388f15f5200411","anchor":{"event_id":"e1db161c8b930b7ac35c129528c573075252e9ed71fd6a82f3b0c8ebd705848b","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-28T05:37:18.365Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-28T05:37:17.300Z","evidence_url":null,"receipt_uuid":"d967dfb4-e9ee-41a9-ae42-f17564ad2cfe","output_sha256":"sha256:c21eb59f4d494388d1f8e9117a0eef1e3a74d9aef24ba88af354376661baae7a","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-28T05:37:17.300Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:c21eb59f4d494388d1f8e9117a0eef1e3a74d9aef24ba88af354376661baae7a\",\"receipt_uuid\":\"d967dfb4-e9ee-41a9-ae42-f17564ad2cfe\",\"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":"2026-10-28T05:37:17.300Z","detail":"The receipt store reports 2026-10-28T05:37:17.300Z; 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.
