Zambo is live: Proof over promises\n\nYour AI tools stack likely faces a specific problem: verifying that your automated workflows actually executed as intended.\n\nZambo solves this by treating every action as a verifiable event. We don’t just run tasks; we generate immutable receipts for them. If a tool call happens, you see the exact bytes saved, the status, and the source. If it fails, the receipt shows the error, not a vague “success” flag.\n\nThis matters because a receipt proves unchanged saved bytes, not necessarily correctness. It distinguishes between “the system ran” and “the system did what you wanted.” In the current AI landscape, that distinction is the difference between trust and liability.\n\nWe are not launching with a list of finished customers. We are launching with a transparent, source-backed verification layer. Our initial checks confirm that when we request research, we get read-only feeds. When we scan for security risks, we get detailed risk labels, not generic warnings. The system is built to show its work.\n\nYou can verify this yourself. The platform operates on a simple principle: no invented findings, no hidden logic. If you need to know if an AI agent actually completed a task, Zambo provides the digital paper trail.\n\n**Next Step:**\nRun one of your recurring workflows through Zambo today. Compare the output against your current logs. If the receipts match your expectations, keep using it. If they don’t, you’ve found a critical gap before your clients did.\n\n[Link to Launch Page]\n\nThe future of AI operations isn’t about faster models. It’s about provable actions.\n\nBest,\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:263bde2e87da86836d59604b91b23853ee3d33d56a14d5dd01df9eaa3b8ecdc1","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":"sha256:99dc96c2fa6db5c1ce8542e5f7d3ed5b36a175ad6d01de41a87266d25c5b4b05","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:d7ef3c356d39b39987a03510e1bf13136f0e0e7695dc56d3085676e1a6e8f3d3","anchor":{"event_id":"df543be899e77367a8b921f6acc75e4ea56fd168cf56d802ea31ca75dae9fc19","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-22T08:17:45.598Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-22T08:17:45.055Z","evidence_url":null,"receipt_uuid":"5aa5eaaf-d9fe-44ed-b253-ba9804d61d8b","output_sha256":"sha256:068137101c65381cc56bc52518785c0050d731a9252e8450acae7604fa64cfd0","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-22T08:17:45.055Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:068137101c65381cc56bc52518785c0050d731a9252e8450acae7604fa64cfd0\",\"receipt_uuid\":\"5aa5eaaf-d9fe-44ed-b253-ba9804d61d8b\",\"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":"2026-10-22T08:17:45.055Z","detail":"The receipt store reports 2026-10-22T08:17:45.055Z; 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.
