Zambo just launched, and it solves a specific pain point: verifying that AI outputs are actually correct, not just plausible.\n\nMost tools give you a receipt that says \"saved.\" That’s not enough. Zambo provides cryptographic trust scores and read-only research feeds that prove the data integrity of your AI workflows. We are not inventing results or faking metrics. If a tool call returns zero leads, we show you the zero. If a scan flags a critical security risk, we show you the flag.\n\nThis launch is about transparency. We built Zambo so you can hand over complex tasks with proof attached, rather than guessing if the backend did what it said it did.\n\n**Your next step:**\n\nUse Zambo to verify one current workflow. Run a simple check on a recent output or a prospective lead list. You will see exactly what we found, with the receipts to back it up. No sales pitch, just the data.\n\nReady to see the proof?\n\n[Link to Verify Your First Workflow]\n\nBest,\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:d14bc6d4ff782f471a90072d14decbb9b943d66efb33df7c67311817ff142474","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:a8ebb522300536be5154db33df2f81efafb14336336acf72786442018dbcca6a","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":"sha256:86407cf34e32f1d71da3b57a6c2aa9c1be3a9737751340a1b5b18263476940a9","anchor":{"event_id":"f69f0266a2b0b199dea857c6981d237b3da54dfd1a6e0372b880db8ab813bd10","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-24T00:38:41.836Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-24T00:38:41.287Z","evidence_url":null,"receipt_uuid":"9b8807e0-23a0-4ef9-817e-b693fb961f3b","output_sha256":"sha256:ec541d5d476ee2bfd90586611f97df73e864fe4ad078db21e86f0ed168b7d219","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-24T00:38:41.287Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:ec541d5d476ee2bfd90586611f97df73e864fe4ad078db21e86f0ed168b7d219\",\"receipt_uuid\":\"9b8807e0-23a0-4ef9-817e-b693fb961f3b\",\"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":"2026-10-24T00:38:41.287Z","detail":"The receipt store reports 2026-10-24T00:38:41.287Z; 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.
