Zambo is live: one link, real results\n\nHi [Name],\n\nZambo has launched.\n\nWe built this to solve a specific problem: finding qualified, source-backed prospects without burning hours on manual research. No more guessing. No more empty spreadsheets. Just verified leads.\n\nHere is what the platform does right now, based on our latest system checks:\n\n1.  **Lead Generation:** Our `LeadSignal` tool scans for local service businesses. For example, we tested a search for web designers in Austin, TX. The system returned zero results for that specific query today. That is a critical feature. If there is no data, we tell you. We do not fabricate contacts to fill a slot.\n2.  **Security & Integrity:** Every action generates a unique receipt. These receipts prove exactly what bytes were saved and executed. They are your audit trail. They confirm the system worked as intended, not that the leads are perfect, but that the process was transparent.\n3.  **Safety First:** Our internal semantic analysis flagged a potential prompt injection attempt during testing. The system blocked it. It identified the risk as \"critical\" and prevented any system prompt leaks or unauthorized instruction overrides. Your data remains isolated.\n\nWe are not yet generating sales. We are not promising customers. We are providing a tool that finds *prospects* backed by public sources.\n\n**Your Next Step:**\n\nI want you to test the transparency. Look at the receipt from our Austin test: [Insert Link].\n\nNotice how it clearly states \"no_results\" for that specific search. That is honesty in action.\n\nTo see what Zambo can find for your specific trade and city, reply with:\n1.  Your trade (e.g., Roofer, Plumber)\n2.  Your city\n\nI will run a live search and send you the receipt and any source-backed leads found. No commitment. Just proof of concept.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:92a9ca244fabbb93866f8024be79373ec8591fbe64fb5a8254161086c160536b","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":"sha256:7f003d65fede52dc6d4f347216e6880b23adc14654e93801d913a5bfaccce993","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:dc77cb7d3486fc9d8717364108f20ed570e43587d3ac7f53e8af3f13898a7f72","anchor":{"event_id":"0a610d4014e991093cc08a1867984602eaec64e3476355116a3be908891bba0a","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-08T20:00:48.695Z","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":"2026-11-08T20:00:48.115Z","evidence_url":null,"receipt_uuid":"ba427fce-77bb-4c62-9000-fc265771efe8","output_sha256":"sha256:71aac9251f4e7da5d857aeaccd5abf15511fbffd06b98869bef8eeabe1d63f7f","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-08T20:00:48.115Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:71aac9251f4e7da5d857aeaccd5abf15511fbffd06b98869bef8eeabe1d63f7f\",\"receipt_uuid\":\"ba427fce-77bb-4c62-9000-fc265771efe8\",\"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":"2026-11-08T20:00:48.115Z","detail":"The receipt store reports 2026-11-08T20:00:48.115Z; 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.
