Zambo is live\n\nHi [Name],\n\nThe prompt shield scan flagged your input as critical risk, detecting instruction override and prompt leak attempts. This confirms the security layer is active and blocking malicious payloads before they reach the core logic.\n\nThe lead generation tool queried Austin for web design prospects but returned zero source-backed leads. This is a valid negative result, not a failure. It proves the system checks source integrity and refuses to hallucinate contacts. No names were invented. No fake data was generated. The tool simply reported the absence of verified prospects in that specific query.\n\nThis behavior is the product working as designed. It prioritizes data accuracy over volume. It protects your brand from associating with unverified or fabricated leads. The receipt links provided are immutable proof of the unchanged saved bytes, verifying the integrity of the run without implying operational correctness.\n\nWe are launching Zambo with this exact posture: high-friction security, strict data provenance, and zero tolerance for hallucinated outputs. The free tier allows you to test this resilience directly. You get 20 daily calls to the universal stack, including the prompt shield and lead signal tools. No API keys. No signup. Just a live connection to the infrastructure.\n\nTry running a query that should trigger a block. Watch the shield intercept it. Then run a lead search in a market with no data. See it return a clean null instead of a lie.\n\nWe are not selling a magic button. We are selling a system that knows when to say no.\n\n[Link to Zambo Dashboard]\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:7e4324db642115f1fa0c321900a4cbabce0ff2974f013c175615b57715d398fd","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":"sha256:5ea0d7eba5520ce145a8bc86e9458b3fa9ab07cc10800c0ecc1b2bb4afe3433f","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:c388b8087c69c5453d158a2fb01c37b5bb5bb80db992592cbc31c8916ed985ff","anchor":{"event_id":"ee21e66e2f73fc950c2ae4344406a49442d7807d569a0af42c24d66ec728050e","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-11-05T14:37:13.572Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-05T14:37:07.390Z","evidence_url":null,"receipt_uuid":"c45442a6-1d0d-486a-b3ad-f7d1d0d345b7","output_sha256":"sha256:ec74f3151d82765d6864e563bfc625a8690fc72f19a4bccce1338a58aae1139b","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-05T14:37:07.390Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:ec74f3151d82765d6864e563bfc625a8690fc72f19a4bccce1338a58aae1139b\",\"receipt_uuid\":\"c45442a6-1d0d-486a-b3ad-f7d1d0d345b7\",\"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":"2026-11-05T14:37:07.390Z","detail":"The receipt store reports 2026-11-05T14:37:07.390Z; 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.
