Zambo solves this by prioritizing verifiable execution over creative guessing.\n\nWe are launching Zambo as a research engine that distinguishes between verified execution and unverified claims. The platform runs semantic scans and pattern checks to ensure every output is grounded in source-backed data. If a tool cannot be executed or verified, Zambo flags it explicitly rather than inventing a result.\n\nThis approach matters because trust is the barrier to adoption. By providing receipts for every run, Zambo allows teams to audit the logic behind AI outputs. You get clarity on what was actually done versus what was merely suggested.\n\n**Next Step:**\nRequest a demo to see how Zambo handles your specific research workflows. We will walk through a live execution plan, showing you exactly how the system validates sources and blocks unverified outputs.\n\n[Schedule Demo Link]\n\nBest,\n\n[Your Name]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:8809c1c8462a72cd08e545909e06f65fa734dffebf3d77180a3061060e6581da","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":"sha256:3740dcf344d704fea4b1026958ebd2120e2cb1225c6e65a78d2ffd3862460501","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:b2b61e6f9c729a0141dcb2bb84a4560d0a5ed3d1a2b26645fa4f5d81581ce8f0","anchor":{"event_id":"4a9575c1f9ccd13784d34774fbfb0bc65dd761f9983ed29176e6a2828ad5c33e","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-27T09:51:49.118Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-27T09:51:48.587Z","evidence_url":null,"receipt_uuid":"2cda9e32-3e0e-4092-ad93-b972c7c2adf6","output_sha256":"sha256:63d93d8dc1c1daef2dad5fe971c505b3bd18522f0ff864d16c3b4f0fe565a23c","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-27T09:51:48.587Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:63d93d8dc1c1daef2dad5fe971c505b3bd18522f0ff864d16c3b4f0fe565a23c\",\"receipt_uuid\":\"2cda9e32-3e0e-4092-ad93-b972c7c2adf6\",\"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":"2026-10-27T09:51:48.587Z","detail":"The receipt store reports 2026-10-27T09:51:48.587Z; 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.
