Now look at the receipt.\n\nMost AI tools give you a result and call it a day. Zambo gives you the result *and* the cryptographic proof that the bytes saved are exactly what was computed. No hallucinated fixes. No invented customers. Just verifiable execution.\n\nWe just completed a live launch check for a web design prospect in Austin. The system scanned semantic patterns, checked injection risks, and executed a capability search. The output? A clean, source-backed run log.\n\nWhen LeadSignal found no leads, it didn’t fabricate a contact. It returned `no_leads` with a clear quota status and a receipt URL. When the capability search ran, it returned read-only research feeds with explicit side-effect declarations. Every step is auditable. Every claim is backed by a hash.\n\nThis isn’t about replacing your judgment. It’s about giving you a safety net that proves the machine did what it said it would do. If a client asks, “How do I know this data is real?” you don’t guess. You send them the receipt.\n\n**Your next step:**\n\nPick one workflow where data integrity matters—client reporting, code generation, or lead verification. Run it through Zambo. Save the receipt.\n\nIf the output matches your expectations and the proof is solid, keep it. If it fails, you have a documented audit trail to debug, not a black box to blame.\n\nUse Zambo to hand this over to your team today. The tools are ready. The proof is waiting.\n\nBest,\n\n[Your Name]\n[Your Title]\n[Link to Zambo Documentation]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:c02bdcac25e3b67c438db7e46465c542e14877ced5a4b96ca9c0e6a841fd5e03","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:f5b78f36865df50a6b53c5ab8da5139acd1652740e86fda34a63f0498276f245","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":"sha256:79a97437160cb0f4be9094a7b6909debae05738686b92e0122639a6c6b80662e","anchor":{"event_id":"fbad13f3dd6e617bcd81f7497b14c1494fe26bfa9408130f4201e6e030cb3a8f","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-28T03:27:17.663Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-28T03:27:17.100Z","evidence_url":null,"receipt_uuid":"b1e6df3d-6c28-4b3b-8d9b-175dd534d987","output_sha256":"sha256:20b2224fa2570d97e6994eb564d98bea2ed4bd77b583fcecc9c210a32be84703","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-28T03:27:17.100Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:20b2224fa2570d97e6994eb564d98bea2ed4bd77b583fcecc9c210a32be84703\",\"receipt_uuid\":\"b1e6df3d-6c28-4b3b-8d9b-175dd534d987\",\"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":"2026-10-28T03:27:17.100Z","detail":"The receipt store reports 2026-10-28T03:27:17.100Z; 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.
