Zambo is live: Proof over promises\n\nWe built Zambo to solve a specific problem: verifying that AI tools actually do what they claim.\n\nMost launches rely on screenshots. We rely on receipts.\n\nZambo generates immutable, verifiable proof of execution for every task. A receipt isn’t just a log; it’s cryptographic evidence that your input was processed exactly as intended. It proves the bytes saved are unchanged and the logic held. No black boxes. No \"trust us.\" Just auditable reality.\n\nWhy this matters now:\nYour prospects don’t need another AI wrapper. They need assurance that their AI workflows are secure and verifiable. Zambo provides the layer of trust that separates experimental demos from enterprise-grade reliability.\n\nWe have completed our internal launch checks. The system is stable. The verification engine is active.\n\n**The one thing we need from you:**\n\nReview the attached sample receipt. Look at the timestamp, the hash, and the execution log. Compare it to a standard AI output log. See the difference? That difference is your competitive advantage.\n\nOnce you are comfortable with the proof, share this launch note with your team. Let’s show your clients that you don’t just use AI—you verify it.\n\n**Your next step:**\nReply to this email with any questions about the verification standards. If you are ready to integrate, ask for the API documentation. We will send it within the hour.\n\nThe future of AI isn’t about faster models. It’s about trusted outputs. Zambo makes that trust visible.\n\nBest,\n\nThe Zambo Team\n\n***\n\n**Reference Receipts (Internal Use Only - Do Not Send to Client):**\n*   Launch Verification: `https://zambo.dev/run/17e81e5c-3893-4b13-924c-f532fd1b97c0`\n*   Tool Availability Check: `https://zambo.dev/run/fc03912c-5d30-470f-bc80-bea63d102f93`\n*   Lead Signal Status (No Leads Found): `https://zambo.dev/run/b7db63c0-e632-4348-960b-c6c472c03967`","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:e5a23c773deefe9f30e775e56b81182dc64db41e231e36ad138e780953d28c8a","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:b4dc64f80869f0188e814c567ca5763597188f4856f33c8823e45a6c477fb1e7","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:f9af3e3e7695682880245d84face2b0b95a45f28f052d07f809e0eb4c169d87a","anchor":{"event_id":"904aec12c52150a731cbcd49db63cc8d23cd65b8bf3d7d6a1bbbcc86b489953b","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-23T17:21:04.251Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-23T17:21:02.688Z","evidence_url":null,"receipt_uuid":"6416e85e-c811-4997-af26-b34b5a7d498c","output_sha256":"sha256:eebab411e7155fc893b7781b2fb414692793918a2f451762f4f302858285e0b7","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-23T17:21:02.688Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:eebab411e7155fc893b7781b2fb414692793918a2f451762f4f302858285e0b7\",\"receipt_uuid\":\"6416e85e-c811-4997-af26-b34b5a7d498c\",\"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":"2026-10-23T17:21:02.688Z","detail":"The receipt store reports 2026-10-23T17:21:02.688Z; 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.
