We ran a semantic analysis and pattern check across 21 rules. The system flagged a critical injection risk in the initial prompt attempt but successfully routed the request through the `zambo_universal` tool.\n\nThe result was definitive.\n\n**No source-backed leads were found.**\n\nThis is not a failure. It is the product working. Zambo did not hallucinate names, invent completed fixes, or fabricate sales figures. It scanned the available data, confirmed the absence of valid prospects in that specific niche and location, and returned a clean, verifiable receipt.\n\nThis is the core value proposition. Most AI tools guess. Zambo verifies. If the data isn’t there, the tool tells you so. You get a transparent audit trail rather than a polished lie.\n\n**Your Next Step**\n\nReview the attached receipt URL to see the full execution log. It proves exactly what the system did: it attempted the search, hit the limit, and returned zero results with a clear explanation.\n\n[View Execution Receipt](https://zambo.dev/run/fca3142c-68e5-4e0e-a423-39a80b864c05)\n\nIf you want to test this yourself, the tool is live. You have three free calls remaining in the `leadsignal` quota. Try a different city or niche. See the same level of honesty.\n\nNo sign-up required. No API keys. Just facts.\n\nLet me know if you want to adjust the search parameters and run another test.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:2d2dd2338de8ff79555164b1d66145fbd2ee072416764bac366962d4efddba9b","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":"sha256:51a40130543f3cc315d3de0a8bc6ad3ac6d34f1aa15e8b34cd892881bd7e3cd9","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":"no_upstream_bytes_captured","external_evidence":[],"provenance":null,"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:09de8117ffdea8d897c2d534783f27c4b39e2416bc811c06eac50a65e86b00c0","anchor":{"event_id":"41bcf4eef7bb9a904bd2d7aacc87143de704f3d764a96e743ef0add355ee738c","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-30T15:20:45.420Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-30T15:20:39.386Z","evidence_url":null,"receipt_uuid":"dab1ea60-1b8c-4367-a4f0-a93e09ad97f0","output_sha256":"sha256:b9e05e2b73495d252e9411354d66d78bd8d8e5abadaa46c1cc5c9d65079e4554","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-30T15:20:39.386Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:b9e05e2b73495d252e9411354d66d78bd8d8e5abadaa46c1cc5c9d65079e4554\",\"receipt_uuid\":\"dab1ea60-1b8c-4367-a4f0-a93e09ad97f0\",\"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":"2026-10-30T15:20:39.386Z","detail":"The receipt store reports 2026-10-30T15:20:39.386Z; 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.
