They invent facts to fill gaps, leaving you to verify every output. That’s a tax on your time.\n\nZambo changes the workflow. It doesn’t just generate text; it executes tasks and proves them.\n\nEvery action Zambo takes returns a cryptographic receipt. This isn’t a marketing claim. It’s a technical guarantee that the exact bytes sent match the bytes saved. If the tool claims it updated your database, the receipt confirms it. If it claims it found a lead, the receipt links to the source. If it fails, you see the failure immediately.\n\nThis matters because trust is the bottleneck in AI adoption. You can’t scale if you have to manually audit every interaction. Zambo removes that audit layer.\n\nWe are launching with a focus on transparency:\n*   **Source-Backed Research:** We distinguish between facts and guesses. Prospects are labeled as prospects, not customers.\n*   **Immutable Logs:** You can trace any output back to its origin.\n*   **No Black Boxes:** If the system encounters a security flag or a dead end, it reports it. It doesn’t hide errors.\n\nWe are not selling \"magic.\" We are selling verifiable automation.\n\n**Next Step:**\nI’d like to show you a live run. I will execute a standard research task in Zambo, generate the receipt, and send it to you. You can click the link and verify the data yourself. No sales pitch, just proof of work.\n\nReply with \"Show me\" and I’ll send the receipt within the hour.\n\nBest,\n\n[Your Name]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:de8b4c545985aa34f43b3ecadf8e63a5d2fcc86652eea21390ed046944880504","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:eb2bb54cf5376a0e0e32bc2882405062960e92bf1f42185b2bd2d9cd67ef1d63","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":"sha256:49315e21f1f074b232d8686feb2b1d9b359624beefadc46474014c7449077a77","anchor":{"event_id":"51d9fd1d155ecdf6bf8f223c85cd745dd23dae06956f8fa3495f7bd3086a144d","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-26T12:15:22.959Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-26T12:15:22.418Z","evidence_url":null,"receipt_uuid":"5be599a8-515c-4fe2-bef3-c958a17346fd","output_sha256":"sha256:0e7a342223e9b761c1bcf6395a7946e42473b15bc36cc182db5e097e79efb8fa","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-26T12:15:22.418Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:0e7a342223e9b761c1bcf6395a7946e42473b15bc36cc182db5e097e79efb8fa\",\"receipt_uuid\":\"5be599a8-515c-4fe2-bef3-c958a17346fd\",\"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":"2026-10-26T12:15:22.418Z","detail":"The receipt store reports 2026-10-26T12:15:22.418Z; 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.
