What matters now is whether the output is true.\n\nZambo bridges the gap between intent and verifiable reality. It doesn’t just run tasks; it generates cryptographic receipts for every action, ensuring that a completed job is backed by immutable data, not just a chat log.\n\nHere is what the current platform delivers:\n\n1.  **Verified Execution:** Every tool call produces a unique receipt URL. This proves that specific bytes were saved or actions were taken. It confirms the operation occurred, though it does not guarantee the semantic correctness of the result.\n2.  **Honest Limitations:** Our LeadSignal module executed a search for web design prospects in Austin, TX. The result was zero leads. Zambo reported this accurately without inventing contacts. That honesty is the product.\n3.  **Semantic Guardrails:** The system detects and blocks malicious injection attempts. When tested, it flagged critical risks like prompt leaks and instruction overrides, refusing to bypass safety policies.\n\nYou are not buying a magic box. You are buying an audit trail.\n\n**Next Step:**\nReview the sample receipt below to see how verification works in practice. If the proof model aligns with your workflow, reply with “approved” to schedule a 15-minute technical walkthrough.\n\nSample Receipt: https://zambo.dev/run/a1df46e9-ae33-4e8c-9c2b-0ca9dc159a8a\n\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:2869773d9d037d172f1ae9311487d8d380d93f06532ada9feb080f8d1969c93a","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":"sha256:4be9883cc527eaa4b5c45bedd2d8a81d0e0feaa5437e7a7381022d87185b3a8d","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:dbc1a1c527bad55f4e4f458a0e1088eff047f8cabd4ca31568f96e4e21cc2991","anchor":{"event_id":"91f52b5c875232d014891d1feef95bd60f8242a77e62cd69e18296645b418a1c","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-21T22:27:52.451Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-21T22:27:51.922Z","evidence_url":null,"receipt_uuid":"2b0bcd86-5906-4fe0-b082-fc940037354a","output_sha256":"sha256:398ea0e75acdff0bb85cb29df9c243e043d8981f942aeef34d976d9e2ce2eb03","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-21T22:27:51.922Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:398ea0e75acdff0bb85cb29df9c243e043d8981f942aeef34d976d9e2ce2eb03\",\"receipt_uuid\":\"2b0bcd86-5906-4fe0-b082-fc940037354a\",\"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":"2026-10-21T22:27:51.922Z","detail":"The receipt store reports 2026-10-21T22:27:51.922Z; 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.
