You need proof.\n\nVeriAI assigns a cryptographic trust score to any AI-generated output. It’s a hard line between \"looks right\" and \"is right.\"\n\nWe’ve integrated this directly into Zambo. When you generate code, copy, or analysis, you get a tamper-evident receipt. If someone alters the bytes later, the signature breaks. You’ll know immediately.\n\nThis matters for two reasons:\n1. **Auditability:** You can prove exactly what your model produced at timestamp X.\n2. **Integrity:** You stop guessing if a downstream process corrupted the data.\n\nI’m not asking you to buy anything yet. I’m asking you to run one test.\n\n**The CTA:**\nGenerate any simple text block through Zambo. Check the receipt link in the footer. Try to edit one character manually. Watch the validation fail.\n\nThat’s the whole product. No dashboards to learn. No API keys to manage. Just a binary signal: trusted or compromised.\n\nIf this solves a compliance headache you’ve been carrying, reply with \"demo\" and I’ll walk you through the integration in 15 minutes. If it’s not relevant, ignore this email. No hard feelings.\n\nBest,\n\n[Your Name]\n[Your Title]\n[Company Name]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:370d842b8fe79494c6da36fea830916a808a2ab67bf1e267666cc18758c7f978","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:c575d8d87c51d1dcf303fa03a4b78767c221e678e1943a94f146c04a3ddf080e","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:d59c2bde45cd75f0d5704fbb070358c9ccac0306e07eb6b5ff57aee701a7792a","anchor":{"event_id":"18081f453f1d45d34a9a624610bd98a7891d1fcc5c7cb0a34b6ac75646b5476b","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-16T14:20:45.950Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-16T14:20:39.921Z","evidence_url":null,"receipt_uuid":"2d7159b4-eb1c-4da4-b2c4-c76e0d25e34b","output_sha256":"sha256:7b9aa3641bff69087b99ae352a42c6190511279a9fd45af9d42a0f23186fc3fa","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-16T14:20:39.921Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:7b9aa3641bff69087b99ae352a42c6190511279a9fd45af9d42a0f23186fc3fa\",\"receipt_uuid\":\"2d7159b4-eb1c-4da4-b2c4-c76e0d25e34b\",\"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":"2026-10-16T14:20:39.921Z","detail":"The receipt store reports 2026-10-16T14:20:39.921Z; 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.
