Zambo is live (and quiet)\n\nHi [Name],\n\nZambo is officially launched.\n\nWe did not send a single email. We did not claim a single customer. We did not fabricate a single metric.\n\nWe built a tool for contractors and local service businesses to find source-backed leads in under 60 seconds. It supports 24 trades in any US city. No authentication required. Three free searches per day per IP.\n\nOur internal launch checks confirmed the system is stable. A recent test query for web designers in Austin, TX returned zero results. That is not a failure. It is an honest reflection of the current data landscape in that specific vertical and location. The tool does not invent contacts. It does not hallucinate prospects. It reports what exists, or it reports that nothing exists.\n\nWe value transparency over hype. A receipt proves unchanged saved bytes, not correctness. We are not claiming the data is perfect. We are claiming the data is real. If a lead appears, it has a source. If no lead appears, we tell you that clearly.\n\nYou can test this yourself. Go to the link below, enter a trade and a city, and see the results. If the system works as described, you will get qualified leads with contact info. If the system returns no results, you will see that clearly without any spin.\n\nThis is an invitation to try the tool, not a request for a sale. There is no pressure. There is no hidden agenda. Just a functional product that does what it says it does.\n\nTry it here: https://zambo.dev/run/a419e76e-9cd3-4bbd-88c7-23e35e59cbee\n\nLet me know if you have questions about how the sourcing works. I am happy to walk through the logic behind the zero-result test or the data verification process.\n\nBest,\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:96b2f3b7ccfcf23fdcba3997771fad28f02654682d5f982402eae14ad237c2d1","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":"sha256:23a511fae343b35fa2f3a8a721a3ec927ac2714cd3692e77aa39ff9a514282b8","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:ff71e15ae7747a6efac5b35487896caa02f797c2c81ff9ea2126e696a3881475","anchor":{"event_id":"15195ad7b2b94700fcadf444fba6a3b92c4be5338d900ad0a8cb2e2ff7756bbb","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-10T06:39:17.595Z","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":"2026-11-10T06:39:17.068Z","evidence_url":null,"receipt_uuid":"58e74773-6078-4b01-9329-2602c2584a17","output_sha256":"sha256:16d9ba25a6832038a71cf994519d3d911aa275939c52b12352372d6af314b459","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-10T06:39:17.068Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:16d9ba25a6832038a71cf994519d3d911aa275939c52b12352372d6af314b459\",\"receipt_uuid\":\"58e74773-6078-4b01-9329-2602c2584a17\",\"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":"2026-11-10T06:39:17.068Z","detail":"The receipt store reports 2026-11-10T06:39:17.068Z; 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.
