We skipped the usual launch hype for something more useful: verifiable proof of work.\n\nMost AI tools promise magic; Zambo provides a trail. Whether you are researching market gaps or verifying output integrity, every action generates a timestamped receipt. It documents exactly what ran, what was found, and what remains unchanged. No black boxes. No \"trust me, bro.\"\n\nWe are currently processing research feeds and lead signals. If a query returns zero results, we log that null state. If a tool executes, we capture the execution plan and the receipt URL. This transparency ensures that when you review a campaign, you are looking at data, not generated confidence.\n\nFor example, a recent scan for Austin web design leads executed fully. The system found no source-backed contacts. Instead of inventing prospects to look busy, Zambo logged the \"no_leads\" status and preserved your quota. That log is your receipt. It proves the system checked, found nothing, and kept your data clean.\n\nThis is the core value proposition: immutable records of AI actions. You get a clear audit trail that distinguishes between a tool’s capability and its actual output.\n\n**Next Step:**\nReview the attached sample receipt from our latest run. Note how it links directly to the execution context without exposing PII or system internals.\n\nIf this level of verifiable transparency fits your current workflow, let’s schedule a 10-minute demo. I can show you how to generate these logs for your specific use case.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:472120f39372b1e3e67fdc370c1091ff0064f3b5861c733785def3d4df3e98c5","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":"sha256:614055b915350e3ca20b44d5dd5b4ea6f4afc8829663daa95c261378c11190e2","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":"sha256:723fbee67fc7310b5cd927bd02d0f0834f1e4fbd14f096985220c95e3d428eef","anchor":{"event_id":"285cf5e77da6a1905d6ad80ec1d0cf9cc6f5e4b15fb0a511eb57eac4b1a0013a","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-22T02:27:45.698Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-22T02:27:45.166Z","evidence_url":null,"receipt_uuid":"e0163d23-9062-426e-b619-c8a3d43dda32","output_sha256":"sha256:a0b8c4a8150bb6a6dd27b174ab2ab490081ed35d45926bee0aaa8505da6ffd6c","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-22T02:27:45.166Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:a0b8c4a8150bb6a6dd27b174ab2ab490081ed35d45926bee0aaa8505da6ffd6c\",\"receipt_uuid\":\"e0163d23-9062-426e-b619-c8a3d43dda32\",\"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":"2026-10-22T02:27:45.166Z","detail":"The receipt store reports 2026-10-22T02:27:45.166Z; 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.
