ject: Zambo is live: proof-backed execution, no hallucinations\n\nHi [Name],\n\nI’m skipping the pleasantries to share what just shipped. Zambo is now live, and it solves a specific problem: verifying that AI actions actually happened.\n\nMost AI tools claim success. Zambo provides receipts.\n\nWhen Zambo executes a task—whether it’s a deep semantic scan or a lead generation query—it generates a unique, verifiable URL. This receipt proves the exact bytes saved and the specific logic executed. It’s not a promise; it’s a digital fingerprint of the work.\n\nWe just ran two live tests to demonstrate this transparency:\n\n1.  **Security Deep Scan:** We analyzed a complex input for injection risks and policy bypasses. The system flagged critical patterns (jailbreak attempts, prompt leaks) with a risk level of \"critical.\" Instead of hiding the error, the tool generated a full audit trail showing exactly which rules triggered and why. The receipt URL remains accessible for any third party to verify the analysis logic.\n\n2.  **Lead Generation:** We queried for web design prospects in Austin. The tool executed the search, found zero source-backed leads, and explicitly reported \"no_results.\" Crucially, it did not invent data to please the user. The receipt confirms the empty state, proving the system prioritizes accuracy over volume.\n\nThis is the core value: **unchanged saved bytes, verified correctness.**\n\nYou don’t need to trust our word. You can click the receipt link and see the raw execution data. Whether you are building AI agents or managing a team that relies on automated workflows, this level of auditability eliminates the \"black box\" anxiety.\n\n**What to do next:**\n\nCopy this email to a colleague who is currently vetting AI tools for their workflow. Ask them to check the receipt structure. If they value verifiable output over generic chat interactions, we should talk.\n\nReply with \"Demo\" if you want to see the live dashboard with these specific receipts attached.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:46b802312df0515135eaeaa71c0916173bce80678186bad65046413265826534","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":"sha256:996e66f93febdadcfa152807f2a1e579fc3172fd0d58b66f8c73f7eb69440d8f","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":"sha256:2835135b8cb8dd401ddc53135170ae7791fdb248cded86255b10e0306dce05bf","anchor":{"event_id":"3b6176bbe37db1586d92bd6dd5b040048d6b03b97616d0f2b2f4cca9bc716315","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-21T09:36:26.411Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-21T09:36:25.856Z","evidence_url":null,"receipt_uuid":"86bf0137-a88a-4c35-80d9-ed2fd86f433f","output_sha256":"sha256:0a8550fb5aa1df8145d08184f6a2658bb90e47f2c147c7122fae7a9bc272bee0","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-21T09:36:25.856Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:0a8550fb5aa1df8145d08184f6a2658bb90e47f2c147c7122fae7a9bc272bee0\",\"receipt_uuid\":\"86bf0137-a88a-4c35-80d9-ed2fd86f433f\",\"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":"2026-10-21T09:36:25.856Z","detail":"The receipt store reports 2026-10-21T09:36:25.856Z; 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.
