It doesn’t guess; it verifies. If you are shipping AI content to clients or users, this removes the \"hallucination liability\" from your stack. Note: VeriAI currently requires a manual web flow via https://veriai.site as we finalize our MCP route.\n\nSecond, **Substrate Layer** is a living AI research machine. It runs 51 adversarial lifeforms to stress-test your hypotheses. It’s a read-only research feed that surfaces breakthroughs you might miss in standard LLM outputs. This tool is fully executable in-chat, free on our tier, and requires zero approval overhead.\n\nWe are not claiming these tools are perfect. We are claiming they address the two biggest gaps in current AI workflows: verification and depth.\n\nIf you are open to testing one of these modules, I’d like to set up a 15-minute call to see if they fit your current stack. No sales pitch, just a look at the receipts and the output.\n\nAre you free next Tuesday or Thursday for a quick chat?\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:9073d4fac9f9a92e6c633795fdcd3a82ee7f70ba581ac010408f93bb9010c10b","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:a9608974f830d0ed73c023a5b4ca95f902cb985eeb4b3e07430cb162ddda9311","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":"sha256:034403ba7cf6749866fe83028afd779d750b7c66beee92b6af3017c399a2f63d","anchor":{"event_id":"431224dbae1e0493ec690cb0ff050c9964f578ad6a35d89e829346676909da13","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-20T19:03:13.453Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-20T19:03:12.931Z","evidence_url":null,"receipt_uuid":"39ef74d7-f424-4254-99d7-01e0dcc5afe7","output_sha256":"sha256:7121a61d3ca1632e1493fb13e65d1a2a618e30ebe8dd138004bbd2ba7d40a268","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-20T19:03:12.931Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:7121a61d3ca1632e1493fb13e65d1a2a618e30ebe8dd138004bbd2ba7d40a268\",\"receipt_uuid\":\"39ef74d7-f424-4254-99d7-01e0dcc5afe7\",\"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":"2026-10-20T19:03:12.931Z","detail":"The receipt store reports 2026-10-20T19:03:12.931Z; 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.
