Zambo Launch: Security First, Hype Last\n\nHi [Name],\n\nMost AI tools promise magic. We provide receipts.\n\nZambo is live. We are skipping the \"fast-paced world\" fluff and focusing on one critical problem: your prompts are leaking, and your models are being jailbroken.\n\nOur PromptShield API detects semantic injection attacks with 18 specific rules. It doesn’t just scan text; it analyzes intent. If a user tries to override system instructions or extract PII, we flag it as critical risk. No false positives from buzzwords. No guesswork. Just binary safety signals you can integrate in milliseconds.\n\nWe know you’re likely testing competitors or building your own heuristics. That’s fine. But heuristics break the moment a new attack vector emerges. Our pattern library updates as threats evolve, ensuring your guardrails stay ahead of the bad actors.\n\nWe are not asking you to buy a subscription today. We are asking you to verify our claims against your own threat model.\n\n**Your Next Step:**\n\nCheck the technical documentation at [Link to Docs]. Specifically, review the \"Deep Scan\" mode output examples. If the logic holds up to your security standards, reply to this email with a single word: **Test**.\n\nWe will provision a free, unlimited access key immediately. No credit card. No sales call. Just a live API endpoint to pressure-test against your current defenses.\n\nIf this doesn’t solve your injection risk concerns, delete this email. We respect your time and your inbox.\n\nIf it does, let’s see what breaks.\n\nBest,\n\n[Your Name]\nFounder, Zambo\n[Link to Website]\n\n***\n\n**Note to Sender:**\n*   **Personalization:** Replace `[Name]` with the actual recipient. If you have a specific prospect (e.g., a CTO at a fintech startup), reference their specific product in the second paragraph to prove you did research, but keep it to one sentence.\n*   **Link Placeholder:** Replace `[Link to Docs]` with the actual URL for your PromptShield API documentation.\n*   **Constraint Check:** This email is under 300 words. It contains no invented customers or sales figures. It positions competitors as \"prospects\" by inviting them to test, not by claiming they have already bought.","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:1c37813934a9cdcd6f6a530804e10c3927325d16713c701678f32c15bee63442","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:e6781ba6e4cd499f18afb97c057706f18c3a507a94e1503ff0d8de626bbaf76c","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":"sha256:2d28f1a09d1b581732d712b9c1c8d584ebbf6972236d0247a02362d9d3abcadb","anchor":{"event_id":"3a7559da2d2b37c998c33f2a0b23550894c24712e00091127261024030906e33","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-20T01:56:41.626Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-20T01:56:41.087Z","evidence_url":null,"receipt_uuid":"51774b74-d0ed-4f3d-868a-61a70da501b6","output_sha256":"sha256:728ee870867ca7ad3d88eb84cd9aee02f34478fcfdfcc7114d9583237de64cd7","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-20T01:56:41.087Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:728ee870867ca7ad3d88eb84cd9aee02f34478fcfdfcc7114d9583237de64cd7\",\"receipt_uuid\":\"51774b74-d0ed-4f3d-868a-61a70da501b6\",\"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":"2026-10-20T01:56:41.087Z","detail":"The receipt store reports 2026-10-20T01:56:41.087Z; 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.
