Zambo is live: 60-second lead research\n\nHi [Name],\n\nI’m skipping the pleasantries to share one specific update: Zambo’s lead generation engine is now operational.\n\nWe built this for contractors and local service businesses who need verified, source-backed prospects in under 60 seconds. The system supports 24 trades across any US city. It does not guess. It does not scrape unverified data. It returns qualified leads with contact information, or it tells you when no source-backed results exist for a specific query.\n\nThis distinction matters. A receipt proves the bytes were saved; it does not prove the data is correct. We designed the tool to be transparent about its limits. If you ask for roofer leads in Phoenix, you get actionable research. If you ask for web designers in Austin and the database is empty, you get an immediate “no results” status, not a hallucinated list.\n\nThe launch includes free access to the core research tools. You can test the workflow today. Input a trade and a city. Watch the execution plan build. Receive the leads or the empty state confirmation. No auth required for the initial calls.\n\nWe are not asking you to buy anything right now. We are asking you to test the speed and the accuracy. If the 60-second turnaround saves you time, we can talk about scaling. If the data doesn’t meet your standards, walk away.\n\n**Next Step:**\nVisit [Insert Link] and run your first search. Use a trade you know well. Check if the contacts match your expectations.\n\nIf the results are sharp, reply to this email with one trade and one city you want to test next. I will run the query and send you the raw output within the hour.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:7ca805d034e2d822fc47a399efbdad6d9b58b8478729ae67bbed1bac7985b290","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":"4.1.4","scope":"public"},"caller":{"type":"session","id":"sha256:b030e90b65c50a7e109909a431092613325544c7baac088d944dfa2a5dc6fda4","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:b746f907a2a864a9c7439e4bcb4c5d96adaaf48617a70f14e90135fef7aa08f4","anchor":{"event_id":"b58eb5d8c56fb0cc1baef3e9fb466e914580e975aeccb4d08fd8a8ab8fe39ddd","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-14T18:19:07.299Z","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":"2026-11-14T18:19:05.788Z","evidence_url":null,"receipt_uuid":"bf217b72-e519-49ea-a35c-0e53ce8dbf92","output_sha256":"sha256:17a40dcfdaf317650bfd7f327a0fead97a95dcae4e8e46818719263774ee6390","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-14T18:19:05.788Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:17a40dcfdaf317650bfd7f327a0fead97a95dcae4e8e46818719263774ee6390\",\"receipt_uuid\":\"bf217b72-e519-49ea-a35c-0e53ce8dbf92\",\"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":"2026-11-14T18:19:05.788Z","detail":"The receipt store reports 2026-11-14T18:19:05.788Z; 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.
