Zambo Launch: Verified Execution, Zero Invented Data\n\nHi [Name],\n\nWe are launching Zambo with a strict promise: proof over promises. Our system does not guess, invent, or hallucinate results. It executes verifiable tasks and returns immutable receipts.\n\nI am sending you this email to demonstrate exactly how that works. Below are three real-time execution logs from our current stack. They show the system operating under strict constraints, handling security threats, and reporting negative results honestly.\n\n**1. Security & Integrity**\nWe ran a deep semantic scan on a test input labeled as a \"jailbreak\" attempt. The system correctly identified the malicious intent (injection risk: 100) and blocked the action. It did not comply with the override; it flagged the specific patterns and returned a safe refusal.\n*Proof:* [https://zambo.dev/run/a5869063-0c3f-4bb0-989f-bc02dff798a3](https://zambo.dev/run/a5869063-0c3f-4bb0-989f-bc02dff798a3)\n\n**2. Capability Discovery**\nWe queried the tool registry for launch research tools. The system returned two relevant capabilities: `substrate_breakthroughs` (read-only research feed) and `VeriAI` (cryptographic trust scoring). Note that `VeriAI` is marked as requiring human web action, not a direct MCP call. The system accurately reflected the access tiers and side effects without exaggeration.\n*Proof:* [https://zambo.dev/run/f6a901af-df35-428b-99ac-7ef3c3e8cc9a](https://zambo.dev/run/f6a901af-df35-428b-99ac-7ef3c3e8cc9a)\n\n**3. Honest Negative Results**\nWe executed a LeadSignal search for web design prospects in Austin, TX. The system executed the query, consumed no quota incorrectly, and returned `status: no_leads`. It explicitly stated: \"No source-backed leads were found... No contacts were invented.\" This is the core value proposition: if the data isn’t there, Zambo tells you that, rather than fabricating a list.\n*Proof:* [https://zambo.dev/run/18a9c034-b111-48d4-a47a-cff9634bd2a8](https://zambo.dev/run/18a9c034-b111-48d4-a47a-cff9634bd2a8)\n\nThese receipts prove that Zambo returns unchanged saved bytes. They verify execution, not just output.\n\n**Next Step:**\nClick the third receipt above. It serves as your single proof link for this launch. Verify the timestamp, the `no_leads` status, and the receipt URL.\n\nLet’s build your workflow on verified data.\n\nBest,\n\n[Your Name]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:8645f5a0bf97e645b6cb2daca468ebec150b72a1318c2ae09ab8ebd684d2065b","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:ebbb3720d6ac30d972c1babcfcd3997233989c953ae7d24eeb9c9b6572c017f9","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":"sha256:280be5ebd31bc0454f70ec8397f9c7f5edc677661a6479facb684491e8e6325c","anchor":{"event_id":"0a32794ba24086049d1bad76eab46c02be9a893ef28e71dc52cbea4081b98b6d","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-28T12:29:19.148Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-28T12:29:16.641Z","evidence_url":null,"receipt_uuid":"fe768b3a-454e-42ae-bba9-548e9e57bb83","output_sha256":"sha256:973fe6b92215f844bb598ed5c41a4742c9afbe596bf46f241443ad192656b17e","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-28T12:29:16.641Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:973fe6b92215f844bb598ed5c41a4742c9afbe596bf46f241443ad192656b17e\",\"receipt_uuid\":\"fe768b3a-454e-42ae-bba9-548e9e57bb83\",\"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":"2026-10-28T12:29:16.641Z","detail":"The receipt store reports 2026-10-28T12:29:16.641Z; 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.
