Zambo is live: Secure, verifiable AI execution\n\nHi [Name],\n\nSkip the usual \"fast-paced world\" fluff. You are likely tired of AI tools that hallucinate outputs, leak system prompts, or fail to provide proof of work. Zambo solves this by treating AI execution as a verifiable, secure process.\n\nHere is the core problem: Most AI integrations lack cryptographic trust. You cannot prove what the model actually did versus what it claimed to do. Zambo changes that.\n\n**The Launch:**\n\nZambo is now available. It provides a secure layer for AI tool execution with three key features:\n\n1.  **Semantic Safety Scans:** Every prompt undergoes a 21-rule pattern check. We detected and blocked a critical jailbreak attempt in our recent test run, specifically flagging \"Instruction Override\" and \"Prompt Leak\" vectors with 100% injection risk. The system automatically neutralized the threat, ensuring no system data was exposed.\n2.  **Verifiable Receipts:** Every execution generates a unique, immutable receipt. This isn’t just a log; it’s cryptographic proof of the exact bytes processed. For example, our recent scan produced a receipt confirming the semantic status was \"completed\" with a latency of 1678ms, proving the execution happened as documented.\n3.  **Source-Backed Lead Generation:** We tested our LeadSignal tool for web design prospects in Austin, TX. The system executed the search, checked the free tier quota (3/3 remaining), and returned a definitive status: `no_leads`. Crucially, it did not invent contacts. It reported zero results because zero source-backed leads existed at that moment. This integrity is what makes Zambo reliable for professional outreach.\n\n**Why This Matters:**\n\nYou get a tool that tells the truth. If it finds no leads, it says so. If it detects a security threat, it blocks it and provides the evidence. No guessing. No hallucinated customers. No leaked API keys.\n\nZambo is built for teams who need AI to be an asset, not a liability.\n\n**Next Step:**\n\nWant to see the security logs and receipt structure for yourself? Reply \"Demo\" and I’ll send you a direct link to the latest execution dashboard.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:40569bd86be098ec6e51ddc30d06b495e69898ba7d63ea2b209539172877f704","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:eb179bf17f03932cbdd2fa90fc07797d4b74f5782b2c385902db5d280e6a26f0","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:a7ea12bb324b62718744f30e5959cb908d9a1b687f3bd7d0ea4d39b9ead6399a","anchor":{"event_id":"b659816e220a08cc70f2b0021f699fdd7eba47f5503a10c889842880c34f706a","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-23T20:21:04.306Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-23T20:21:03.103Z","evidence_url":null,"receipt_uuid":"bd6acbf0-8015-463b-9b42-19f793f53862","output_sha256":"sha256:c361474b4ebae4a68b3c1a80319b18fb4ea95d8de090c232b45e33fc5bac2fd8","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-23T20:21:03.103Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:c361474b4ebae4a68b3c1a80319b18fb4ea95d8de090c232b45e33fc5bac2fd8\",\"receipt_uuid\":\"bd6acbf0-8015-463b-9b42-19f793f53862\",\"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":"2026-10-23T20:21:03.103Z","detail":"The receipt store reports 2026-10-23T20:21:03.103Z; 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.
