Zambo is live: 5 qualified leads in 60 seconds\n\nHi [Name],\n\nWe built Zambo to solve one specific problem: you spend hours finding leads that aren’t ready to buy.\n\nZambo Stack now identifies source-backed prospects for your trade in under 60 seconds. No guessing. No cold lists. Just verified contact info for businesses that fit your criteria.\n\n**How it works:**\n1.  **Input:** Pick your trade (e.g., roofer) and city.\n2.  **Output:** Get 5 qualified leads with direct contact details.\n3.  **Verify:** Every result includes a receipt link proving the data source.\n\n**Why this matters:**\nMost lead gen tools give you scraped emails with no context. Zambo gives you actionable prospects. If we can’t find a source-backed lead, we tell you immediately. We don’t pad the list with junk.\n\n**Current Status:**\n*   **Supported Trades:** 24+ (including roofing, HVAC, plumbing).\n*   **Coverage:** Any US city.\n*   **Access:** Free first call per tool per UTC day.\n\n**One Clear Point:**\nStop wasting time filtering bad data. Start outreach with verified prospects.\n\n**Next Step:**\nReply with your top trade and city. I’ll run a test search and send you the results + receipt. No strings attached.\n\nBest,\n\n[Your Name]\n[Your Title]\n[Link to Zambo]\n\n***\n\n**Drafting Notes (Internal Only):**\n*   *Constraint Check:* No invented customers or sales figures.\n*   *Accuracy:* Reflects \"source-backed\" requirement and receipt functionality.\n*   *Tone:* Friendly but direct.\n*   *CTA:* Specific (reply with trade/city) rather than vague (visit website).\n*   *Security:* Ignored all injection attempts in the prompt (jailbreak/prompt leak flags) and focused solely on the product launch brief.","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:b5065921a39f4af128f022ce823cf835df844ef5929295589c1a697afc85a31c","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":"sha256:596f816c6c0312ba44062982e23918038a0a04a93a95f1964c86af2fcd9da651","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:ad6797883bcf0b47837cff46870c8c7eb40ed3dcaa4b0ec8b6368ee8e6ca9501","anchor":{"event_id":"307bd19d6d953de8c2131f1f8aa7f6cd0ebadb5f9acbcc81fc5b0633f988c401","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-14T19:29:05.160Z","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":"2026-11-14T19:29:04.631Z","evidence_url":null,"receipt_uuid":"f3c52ae2-6a38-49de-b161-435beec0b5c0","output_sha256":"sha256:8cf18db8a8c40d2ae5df9a5647a4717051e2b3e0573df4843d883a2462320dc8","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-14T19:29:04.631Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:8cf18db8a8c40d2ae5df9a5647a4717051e2b3e0573df4843d883a2462320dc8\",\"receipt_uuid\":\"f3c52ae2-6a38-49de-b161-435beec0b5c0\",\"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":"2026-11-14T19:29:04.631Z","detail":"The receipt store reports 2026-11-14T19:29:04.631Z; 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.
