Zambo is live: 21 rules, zero noise**\n\nHi [Name],\n\nNo fluff. We aren’t selling a “fast-paced” solution. We are shipping a tool that works.\n\nZambo is here. It analyzes prompts against 21 specific semantic and pattern rules. It catches injection risks and jailbreak attempts before they hit your backend. The result? A clear, actionable report. No guesswork. No false positives masking real threats.\n\nLook at the recent scan for a standard launch check. The system flagged a critical instruction override attempt. It identified a prompt leak vector. It returned a definitive risk level. It took 1.3 seconds. That speed matters. You cannot afford blind spots in your AI layer.\n\nWe built this because existing scanners miss the nuance of semantic manipulation. They look for keywords. Zambo looks for intent. The difference is the difference between a blocked attack and a compromised system.\n\nYou can see the capability in action right now. We ran a test query through the full stack. The system routed the request, executed the semantic analysis, and returned a detailed breakdown. It flagged two distinct patterns: an Instruction Override and a Prompt Leak Attempt. The severity was marked critical. The reasoning was explicit. This is transparent security. You know exactly what is wrong and why.\n\n**What you can do next:**\n\nRun a single test prompt through Zambo. Use the public interface. Observe the output. See how it isolates malicious intent from legitimate queries. If it catches what you throw at it, you have a secure foundation. If it doesn’t, we need to talk about your specific edge cases.\n\nWe aren’t asking for a meeting yet. We are asking you to test the tool. It’s free. It’s fast. It’s built for developers who care about precision.\n\nCheck the receipt from our internal test run here: [Link]. It shows the exact input, the processing time, and the detected threats. Transparency is our baseline.\n\nGive it a shot. Let me know what it catches.\n\nBest,\n\n[Your Name]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:4705f49587b06811e00c9297a680456eeb74f87066e82b65604b285f15c59017","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":"sha256:788bdb2d422b46a4279a12d7a0debe72945d51198e9ce4e59b995d8d9e966218","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":"empty","result_source":null,"evidence_source":null,"external_evidence":[],"provenance":{"result_source":null,"evidence_source":null,"evidence_status":"empty","evidence_captures":[]},"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:60a181b8629f18e2870f27c3da90dd0df9b9c9c6a2cfe481329414a3f089efae","anchor":{"event_id":"ea95cb6398f38084330d1634271618f6a9850dc6e936f919ff8fd865bebf59bb","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-31T16:00:36.383Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-31T16:00:30.348Z","evidence_url":null,"receipt_uuid":"321454d0-17f6-4907-928d-6ea98a07958a","output_sha256":"sha256:fca622ec2e8e7ac967c9eda5815c5e3d1b7eae0bbe7952a1b8a69429f66c56be","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-31T16:00:30.348Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:fca622ec2e8e7ac967c9eda5815c5e3d1b7eae0bbe7952a1b8a69429f66c56be\",\"receipt_uuid\":\"321454d0-17f6-4907-928d-6ea98a07958a\",\"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":"2026-10-31T16:00:30.348Z","detail":"The receipt store reports 2026-10-31T16:00:30.348Z; 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.
