The system returned zero source-backed prospects.\n\nThis confirms the tool is functioning as designed: it only outputs verified, real-world data. It does not hallucinate contacts or fill gaps with fake leads. When the database is empty, the tool says so. That is the feature, not a bug.\n\nZambo’s value lies in its refusal to guess. For contractors and local service businesses, a single wrong email address can damage a reputation. We built Zambo to prioritize accuracy over volume. If we cannot verify a lead, we do not show it to you.\n\nThe receipt for this specific empty search is attached below. It proves the system executed the query and returned a clean, honest result.\n\nWe are ready to launch with that same integrity.\n\nCTA: Reply with \"GO\" to approve the launch timeline.\n\nBest,\n\n[Your Name]\nFounder, Zambo\n\nReceipt: https://zambo.dev/run/f85a674d-35c3-44e1-a684-5d1c195bec0f","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:266dbb258d2eb922a6959eb70d5f7fb55c05a1f23b188932a92b8fa5433cfe7c","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":"sha256:327ee69228e917d2a6d341e4445dd026a76e496c2f19c41cf439514fc7ee24d4","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":"sha256:251a494c8fddb79069219daa2f8e6f542b1bdc845be875668db76e3032b287f0","anchor":{"event_id":"ef68b1cbfe1a7919371b3eafa7a4874b59fbd54f648cac1a88cc250cf8541857","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-09T06:18:22.576Z","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":"2026-11-09T06:18:22.062Z","evidence_url":null,"receipt_uuid":"c4e56c18-59b6-481f-9881-16af6c5f1200","output_sha256":"sha256:1626c222abf77ab0f0e515af66ef075b277b0ca256f1c644aa134e467a2eb8f0","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-09T06:18:22.062Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:1626c222abf77ab0f0e515af66ef075b277b0ca256f1c644aa134e467a2eb8f0\",\"receipt_uuid\":\"c4e56c18-59b6-481f-9881-16af6c5f1200\",\"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":"2026-11-09T06:18:22.062Z","detail":"The receipt store reports 2026-11-09T06:18:22.062Z; 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.
