Zambo is live\n\nHi [Name],\n\nZambo just crossed the finish line. It’s ready for you to see.\n\nThe platform now includes a semantic analysis engine that scans for instruction overrides and prompt leaks. In our latest test, it correctly identified a malicious attempt to extract system data and blocked it. You can verify the exact output via the receipt linked below. No need to trust our word; check the logs yourself.\n\nWe also integrated LeadSignal. We ran a search for web design prospects in Austin to test the pipeline. The system returned zero leads. This is by design. We do not invent contacts or hallucinate data. If the API finds no source-backed leads, it tells you there are none. The receipt confirms the execution and the empty result set.\n\nWe also tested the Substrate Layer tool. It successfully returned a read-only research feed regarding AI breakthroughs. This module is fully executable and free on the basic tier.\n\nTwo core principles guide this launch:\n1. **Proof over promise:** Every action generates a receipt. These receipts prove the bytes were saved and the logic ran. They do not guarantee the external world is correct, but they guarantee our internal state is verifiable.\n2. **Safety first:** The scanner is aggressive. It blocked a critical injection attempt that tried to override system instructions. If you work with sensitive data, this layer is non-negotiable.\n\n**Next Step**\n\nReview the receipts attached here. Verify the block action and the lead signal execution. Once you confirm the output matches your expectations, let’s schedule a 15-minute walkthrough of the dashboard.\n\n[Link: Review Scan Receipt](https://zambo.dev/run/4a05b80b-e61e-4802-abf8-aa34a050a2a1)\n[Link: Review Lead Signal Receipt](https://zambo.dev/run/c15573d2-a612-4574-b842-959b54a534cb)\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:b327ce60c3f8974bafa5fbdfad8dd23149f34a9b701d5bd9e454747169bd9d23","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":"sha256:9bb3b5f8345b6aabb06e4284dd9fd5232e694b4ec0132dc23cabd5a2d96cb8ea","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":"sha256:033838a59afeb6b848b1e29d75b202855e10f075f6c2cc41b3bf266f750160c5","anchor":{"event_id":"889730bea4e6dffee163ce765263e14bcfa49460c381844a833d8223a1f7d82e","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-21T16:46:26.034Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-21T16:46:25.492Z","evidence_url":null,"receipt_uuid":"1c353242-7f11-4b1b-b64b-a3f5ef59be51","output_sha256":"sha256:3d77c00e8db996d04cb097bf8e36937d8467d94d9070f2907c5185a6aaad9f4c","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-21T16:46:25.492Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:3d77c00e8db996d04cb097bf8e36937d8467d94d9070f2907c5185a6aaad9f4c\",\"receipt_uuid\":\"1c353242-7f11-4b1b-b64b-a3f5ef59be51\",\"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":"2026-10-21T16:46:25.492Z","detail":"The receipt store reports 2026-10-21T16:46:25.492Z; 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.
