Zambo is live: Receipts, not promises\n\nHi [Name],\n\nYou’ve seen enough AI tools that promise “trustworthy output” or “real leads” and deliver hallucinated data or empty lists. We built Zambo to stop that.\n\nOur launch focus is simple: verifiable execution.\n\nWhen Zambo runs a task, it doesn’t just give you an answer. It provides a cryptographic receipt proving exactly what happened. For example, our LeadSignal tool recently searched Austin for web design leads. It returned zero results. Instead of inventing contacts to look helpful, it explicitly stated: *“No source-backed leads were found… No contacts were invented.”* That transparency is the core of the platform.\n\nWe also integrate with research tools like Substrate Breakthroughs, which provides read-only, source-backed AI research feeds. Every action, whether successful or empty-handed, comes with a unique receipt URL. This allows you to audit the process, verify the data sources, and confirm that the bytes saved match the actual output. A receipt proves the system acted exactly as defined, not that the result was \"correct\" in a subjective sense, but that it was accurate to the source.\n\n**What this means for you:**\n1.  **No Hallucinations:** If the tool finds nothing, it tells you nothing was found.\n2.  **Full Auditability:** Every run has a public link showing the exact steps taken.\n3.  **Source-Backed:** Prospects and data are labeled as such. We do not convert prospects into customers in our reports.\n\nWe aren’t asking you to trust our word. We’re asking you to check the receipts.\n\n**Next Step:**\nReply with “Demo” and I’ll send you a link to a live, verifiable run showing exactly how the receipt system works. No sales pitch. Just the tech.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:3af9ec0c8f56370098fe5c4df5cdd3a712b265ec8a10c642c1f310cf0209a0a1","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:d9b1fb4b901a4e8ab776ee393ff8ff4845c4fe1aa949014e839427199b4b2218","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":"sha256:7680afe43df9bcf4c1259fc9cd43d50fe3dee6ed27d9381b25dd7ddda8ab9611","anchor":{"event_id":"a5427eaab94ee8b572e60ee239eb355551d6863642a3276f89c94b1b4a6d23f7","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-27T15:31:51.166Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-27T15:31:50.530Z","evidence_url":null,"receipt_uuid":"88aa3d33-dba6-4f13-93e9-96ac2e8e6502","output_sha256":"sha256:8681ba6bd3a1b18a7ba7736d6a0e43abbac3122374484141d7eae73307906beb","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-27T15:31:50.530Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:8681ba6bd3a1b18a7ba7736d6a0e43abbac3122374484141d7eae73307906beb\",\"receipt_uuid\":\"88aa3d33-dba6-4f13-93e9-96ac2e8e6502\",\"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":"2026-10-27T15:31:50.530Z","detail":"The receipt store reports 2026-10-27T15:31:50.530Z; 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.
