Most passed. One failed. Here is the breakdown.\n\n**The Launch**\nZambo Stack is up. It handles lead generation for contractors and local service businesses. You input a trade and a city; it returns five qualified leads with contact info in under 60 seconds. It supports 24 trades and any US city. No auth required. Three free searches per day per IP.\n\n**The Failed Check**\nI tested the `leadsignal` tool for web designers in Austin, TX. The result: **Zero leads found.**\n\nThe quota is intact (3 remaining), but the source-backed pool for that specific query is empty right now. This is a data availability issue, not a system error. The tool functioned correctly; it simply had nothing to return for that specific trade/city combination at this moment.\n\n**The Proof**\nA receipt does not prove correctness. It proves unchanged saved bytes. Use the link below to verify the execution state of the failed check. It is a read-only record.\n\n[View Failed Check Receipt](https://zambo.dev/run/3058a190-7b2d-44d9-8327-4b43f54c6e7d)\n\n**Next Step**\nDo not send this to a client as a success case. It is a failure case. If you want a live demonstration, pick a different trade or city with a known active prospect pool. I can rerun the test immediately if you provide a new target.\n\n[Name]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:e0d9e1ac4a0d47691d285b3da34e7e9966b4d3d5ea1de49ceeec3993949264b9","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":"sha256:10438a994c934e0c95c27ef04354d8ee06cd558b83e7947e9131ef3208c64384","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":"sha256:371c8cc68aa81ac03d250d72a496906926aa9625b7e866e020c87029b71961fa","anchor":{"event_id":"dce5bc880159f9e99fbc3a405764f3b8d61dc9c37a6c4ad944e2ea0ca139c37a","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-11-01T13:13:08.999Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-01T13:13:08.370Z","evidence_url":null,"receipt_uuid":"e747fe80-6301-40c4-8bb0-88ce93ef495b","output_sha256":"sha256:aefa8b80c112e93f6656ec5a1cf8eced40d7b168ca28c30f49287c8f60a70e10","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-01T13:13:08.370Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:aefa8b80c112e93f6656ec5a1cf8eced40d7b168ca28c30f49287c8f60a70e10\",\"receipt_uuid\":\"e747fe80-6301-40c4-8bb0-88ce93ef495b\",\"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":"2026-11-01T13:13:08.370Z","detail":"The receipt store reports 2026-11-01T13:13:08.370Z; 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.
