The launch checks confirm the system is functioning as intended, with zero errors in the execution path.\n\nThe core capability is proven. LeadSignal successfully executes source-backed research for AI tools targeting local service businesses. It does not invent contacts; it verifies data. Current status shows the tool is fully executable, with a free tier allowing three searches per day without authentication.\n\nWe ran a test query for web design leads in Austin, TX. The system returned `no_results`. This is a correct, verified outcome, not a failure. It confirms the tool is strictly adhering to source-backed verification. It will not hallucinate prospects. A receipt exists for this exact run, proving the saved bytes remain unchanged and the logic holds.\n\nThis is the product promise: precision over volume. When Zambo finds a lead, you can trust the data. When it finds nothing, you know why. No fluff, no fake names, no wasted time.\n\nNext steps are simple. You have two options:\n\n1.  **Verify the proof:** Click this link to see the full receipt of the last run, including the semantic analysis and policy checks.\n    https://zambo.dev/run/bda13a2e-ca62-4dce-b366-61f6f081329f\n\n2.  **Run your own test:** Use the free tier to search a trade and city of your choice. Verify the results yourself.\n\nNo sales pitch. No pressure. Just a working tool that respects your time and data integrity.\n\nLet me know if you want to dive into the technical specs or if you have questions about the verification process.\n\nBest,\n\n[Your Name]\n[Your Title]\n[Company Name]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:73ba1b57d27b088450fc2f37540d91ac1639c176ae3c3aaf2061118918ae55ad","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:a9df60f44a942e62247cb053503853e2e8314f5889ccb6cfc29aa63a585d61eb","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:b20db20642898a8e13bfa0b9d9d40ae50ccbaee3aa8c16d68aee6361171deba0","anchor":{"event_id":"468952199b4f9a50178344d66efe66dc5f1cc1838321295de189d0e3c5474751","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-09T08:28:22.127Z","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":"2026-11-09T08:28:21.587Z","evidence_url":null,"receipt_uuid":"0482a011-a55c-4576-928a-4c87d9511ef1","output_sha256":"sha256:2525d9017e172446091083ef0e5a3704e86ea9409eed866b06c95869b75d58a2","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-09T08:28:21.587Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:2525d9017e172446091083ef0e5a3704e86ea9409eed866b06c95869b75d58a2\",\"receipt_uuid\":\"0482a011-a55c-4576-928a-4c87d9511ef1\",\"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":"2026-11-09T08:28:21.587Z","detail":"The receipt store reports 2026-11-09T08:28:21.587Z; 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.
