Zambo is live (and honest about what it can do)\n\nHey [Name],\n\nCutting the fluff: Zambo is officially out.\n\nWe built this because finding qualified leads for local service businesses shouldn’t require a PhD in data scraping or a marketing budget. Zambo Stack takes a trade and a city, then returns five source-backed prospects with contact info in under 60 seconds. No ghost data. No hallucinations.\n\nHere is the reality check on where we are right now.\n\nWe tested the system. We ran a query for web designers in Austin, TX. The result was zero matches. The tool reported \"no_results\" and stopped there. It did not invent a roster. It did not guess. It simply told us the truth about that specific moment.\n\nThat is the core promise. A receipt proves the bytes saved were unchanged; it does not prove the data is correct. We are not selling you magic. We are selling you a fast, transparent research engine that respects the source. If the data isn’t there, you know immediately. You don’t waste time chasing ghosts.\n\nFor this launch, we are keeping the scope tight. You get 24 trades and any US city. You get three free searches per day per IP. No auth walls slowing you down. If the tool finds leads, you get the draft message. If it doesn’t, you get a clean exit.\n\nWe are not claiming to have solved lead gen overnight. We are claiming to have built a tool that doesn’t lie to you when the answer is \"no.\"\n\nWant to see it run on your niche?\n\nReply with your trade and city. I will run the search and send you the live receipt link so you can verify the output yourself. No pitch. Just the data.\n\nBest,\n\n[Your Name]\nZambo Founder","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:54855648d6fa88a563a808ca695bde58a626e9d906c3cb117f507c0a396695ec","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":"sha256:9236bcd077142a6456ce9f68b2bd46003be0209a3d8cd44114bf189cd927cd88","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":"empty","result_source":null,"evidence_source":null,"external_evidence":[],"provenance":{"result_source":null,"evidence_source":null,"evidence_status":"empty","evidence_captures":[]},"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:14bda4e08f609df9a5186db010c6c2acb6ee36d747f9d0cbbd09fb869374e81a","anchor":{"event_id":"7b6dec5f2a2577f2aaf83871f407d5686126737679355a7e7b5e4dd7a955ad17","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-09T11:45:34.500Z","published_at_semantics":"Relay confirmation time (accepted acknowledgement or exact-event read-back); not the signed event's created_at.","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-09T11:38:21.244Z","evidence_url":null,"receipt_uuid":"4cd1b880-0e50-4dab-8f87-92f5bfbb9aac","output_sha256":"sha256:7e0342de293cb7d77e04fbadff5775a984efc4b4a0b2a2b289d5f1c0b26cd2f9","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-09T11:38:21.244Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:7e0342de293cb7d77e04fbadff5775a984efc4b4a0b2a2b289d5f1c0b26cd2f9\",\"receipt_uuid\":\"4cd1b880-0e50-4dab-8f87-92f5bfbb9aac\",\"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":"2026-11-09T11:38:21.244Z","detail":"The receipt store reports 2026-11-09T11:38:21.244Z; 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.
