Zambo has launched.\n\nWe built this because “trust me” isn’t enough in AI. You need receipts.\n\nEvery run generates a verifiable proof of execution. It’s not a vague claim; it’s a link to the exact data that was processed. If the tool fails, you see the error. If it succeeds, you see the source. No black boxes. No guessing.\n\nYou can verify the output directly without taking our word for it. That’s the core promise: transparency you can audit.\n\n**Your next step:**\nClick the receipt link below to inspect a live run. Check the timestamp. Verify the output.\n\n[Link to Receipt]\n\nThis isn’t a demo. It’s the production environment.\n\nIf the proof holds up, you’re ready to move forward. If not, we know exactly where to fix it.\n\nBest,\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:8e8b0ef09d164d1248befac311174cfa61db7c2f4d2740e4b8d0857ba7fd6c21","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:f1c463b0a6e14b1d44e23b8ff493efff5d12eafbd8966b59afb71e5dc3eae46c","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:fdb67ff05c43163fa399ff6a2d93ce6539213001c7d06f5d67a978bc0abfec14","anchor":{"event_id":"39ba87aaf207d77b0449c3db4fda3ca63d9cc432e0e6568e392fba3c203d0af9","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-27T13:41:49.372Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-27T13:41:48.817Z","evidence_url":null,"receipt_uuid":"bbb9544e-c853-4123-99fc-8291855dd492","output_sha256":"sha256:677c47d21f70aabc8894a7e3f402db161d5b90e878b292e306c9d2c14ba9e478","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-27T13:41:48.817Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:677c47d21f70aabc8894a7e3f402db161d5b90e878b292e306c9d2c14ba9e478\",\"receipt_uuid\":\"bbb9544e-c853-4123-99fc-8291855dd492\",\"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":"2026-10-27T13:41:48.817Z","detail":"The receipt store reports 2026-10-27T13:41:48.817Z; 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.
