Zambo is live: Your first proof link\n\nHi [Name],\n\nZambo is officially online. We moved fast on build, but we stayed disciplined on scope. No vaporware, no fake metrics. Just a working tool that solves a specific problem for local service businesses.\n\nHere is the reality of the launch so far:\n\n1.  **Core Functionality:** LeadSignal is operational. It scans public sources to find qualified leads for 24 trades in any US city.\n2.  **Current Status:** Our initial test query for web design prospects in Austin, TX returned zero results. This is a data availability issue, not a system failure. The tool correctly identified that no source-backed leads existed for that specific combination at that moment.\n3.  **The Proof:** We don't claim the output is \"correct\" in a subjective sense. We claim the output is **accurate to the source data**. The receipt below proves the system executed the search, queried the database, and returned the raw result (empty) without hallucinating contacts.\n\nThis transparency matters. Many AI tools invent data to look successful. Zambo does not. If the data isn't there, it tells you the data isn't there. That reliability is the product.\n\n**Your Next Step:**\n\nClick the link below to view the execution receipt. It shows the exact query, the timestamp, and the raw response. Verify the integrity of the search process.\n\n[View Execution Receipt: Austin, TX Search](https://zambo.dev/run/4567989f-51c2-4941-bb3b-5084a3af0d6f)\n\nWe are ready to run your first real search. Pick a trade and a city where you know leads exist. We will show you the source-backed prospects in under 60 seconds.\n\nLet’s test it on your market.\n\nBest,\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:8f16406c3d252a60b775f0b58144244ad886dcd264cff59288fb0450733233ca","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:d5346722af1b1f102c5b32888f649d12bb4c137ac852a7941b656f0cb644744c","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:d34aaaac9e2904de09aaac6b46b3501b74505efb0608f1256349eceec2e20d58","anchor":{"event_id":"1918a61cda47d75868e8fcf00e904fb55f4133ab23e3f1126be88ee9651f6db6","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-08T22:06:45.382Z","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":"2026-11-08T22:06:44.834Z","evidence_url":null,"receipt_uuid":"594125f6-d1b7-4479-abbd-753ea9c8e179","output_sha256":"sha256:e98f85d0f62f93ba4c9ae301bfdf3800c77a7854c7d0a1f98ce5c140cab57228","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-08T22:06:44.834Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:e98f85d0f62f93ba4c9ae301bfdf3800c77a7854c7d0a1f98ce5c140cab57228\",\"receipt_uuid\":\"594125f6-d1b7-4479-abbd-753ea9c8e179\",\"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":"2026-11-08T22:06:44.834Z","detail":"The receipt store reports 2026-11-08T22:06:44.834Z; 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.
