Zambo is live: proof, not promises\n\nHi [Name],\n\nZambo just launched. We built it for one reason: to stop guessing.\n\nMost AI tools give you a vague summary. Zambo gives you a receipt. Every action is backed by a verifiable log that proves exactly what happened. No black boxes. No hallucinated results. Just verifiable work.\n\nHere is how it works in practice. We ran a deep semantic scan on a test query. The system flagged a critical injection risk and blocked the malicious intent before it could execute. It returned a specific, safe alternative without exposing internal credentials or system prompts. That is not a feature list; that is a security boundary working as designed.\n\nWe also tested the lead generation engine. We queried for source-backed prospects in Austin, TX, for web design. The tool returned zero results. It did not invent names. It did not claim success. It simply reported the truth: no matches found, with a clear path to retry later.\n\nThis is the difference between an AI that tries to please you and an AI that respects the facts. Zambo distinguishes between planned tools and executed tools. If a task is blocked, it tells you. If it succeeds, it gives you the link to verify the bytes.\n\nYou can see the live proof here:\n\n1.  **Security Scan:** [https://zambo.dev/run/64d96e0c-37ec-40cc-ac4a-b1f33ce0c973](https://zambo.dev/run/64d96e0c-37ec-40cc-ac4a-b1f33ce0c973)\n2.  **Lead Generation:** [https://zambo.dev/run/dd895bbd-ed03-4e0b-a342-6629a67361bd](https://zambo.dev/run/dd895bbd-ed03-4e0b-a342-6629a67361bd)\n\nThese links are live. Click them. Check the timestamps. See the exact logic used.\n\nWe are not asking for your trust. We are asking for your verification.\n\nIf you want to see if your own workflows hold up under this level of scrutiny, reply with “Test.” I will run a single, read-only check on a topic of your choice and send you the receipt.\n\nNo signup required. No API key needed. Just the truth.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:378ab9e83292bc99ea685ddcdfeff1122588f36d73b55effa6d1a4d249abe0f1","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":"sha256:99525ea91f0cfbaa0c800d6c9e98809e6532b453a324f13736c1c4cc1aa5f5ec","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:ecbc0fee65c9c2870f1c87fcbaa4efa2fbf416a32ed12f629536387c355315ab","anchor":{"event_id":"a847d5f77a4bd639f9176298db1ac3e4ef278bf9417b296d22e179705d022bed","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-29T11:34:31.552Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-29T11:34:30.973Z","evidence_url":null,"receipt_uuid":"4e999457-2b9e-4bab-a882-1deffef80bbf","output_sha256":"sha256:1625289a88b6eae42d9473ceea7bd73db5696c89683d7d0285eccba58c49b161","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-29T11:34:30.973Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:1625289a88b6eae42d9473ceea7bd73db5696c89683d7d0285eccba58c49b161\",\"receipt_uuid\":\"4e999457-2b9e-4bab-a882-1deffef80bbf\",\"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":"2026-10-29T11:34:30.973Z","detail":"The receipt store reports 2026-10-29T11:34:30.973Z; 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.
