Zambo is live: Proof over promises**\n\nHi [Name],\n\nMost AI tools ask for trust. Zambo asks for receipts.\n\nWe just launched a workflow engine that doesn’t just execute tasks—it verifies them. Every action generates a cryptographic receipt proving exactly what happened, byte-for-byte. No black boxes. No \"trust me, it worked.\" Just verifiable output.\n\nRight now, our test runs show two distinct paths for our early users:\n\n1.  **Deep Semantic Scanning:** We ran a 21-rule pattern check on a complex prompt. The system flagged a critical injection risk and a prompt leak attempt in under 1.1 seconds. It didn’t just warn you; it identified the specific attack vector (`instruction_override`) and provided a safe, sanitized version of your intent.\n2.  **Grounded Lead Research:** We queried for web design prospects in Austin. The system executed the search, found zero real leads, and explicitly stated: *“No contacts were invented.”* It saved you time by confirming the market gap rather than hallucinating fake data to please you.\n\nThis is the core of the Zambo Pass. You get unlimited free calls to the `substrate_breakthroughs` tool, which acts as a living research feed. It returns source-backed data or tells you when the data isn’t there.\n\n**Your Next Step:**\n\nReply with **“TEST.”**\n\nI’ll send you a link to run a single, free verification scan on one of your current workflows. You’ll see the receipt, the latency, and the exact breakdown of what was flagged. If it doesn’t save you an hour of debugging or prevent a data leak, you don’t have to talk to me again.\n\nNo pitch deck. No sales call. Just a link and a result.\n\nBest,\n\n[Your Name]\nFounder, Zambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:ae0b43f88e7d692a376bebeceeece50ab9ae4f1aa2c6996e7529ec34bac2042c","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":"sha256:9e31102f725e5230b2da88e133fe89d82218cd96a16998c315643699e7bddc68","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:c25c574b2cbb211954d57e91853d53fe8c106db700a8171d91d559290c6d23a0","anchor":{"event_id":"e1b2aefbc6676b6ca6f72d9c517437c15c83624e893cc5544e5992a815531846","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-26T18:37:51.485Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-26T18:37:50.928Z","evidence_url":null,"receipt_uuid":"54b635c8-5a97-4449-b7dd-2296ac59d34a","output_sha256":"sha256:e44102b7ccb465af1a56fa90df35b45ca54730f83aa03f9a9a9574f422210437","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-26T18:37:50.928Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:e44102b7ccb465af1a56fa90df35b45ca54730f83aa03f9a9a9574f422210437\",\"receipt_uuid\":\"54b635c8-5a97-4449-b7dd-2296ac59d34a\",\"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":"2026-10-26T18:37:50.928Z","detail":"The receipt store reports 2026-10-26T18:37:50.928Z; 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.
