Zambo addresses this by providing a read-only research feed that surfaces high-signal insights without requiring you to build your own scraping infrastructure.\n\nWe are currently in our initial launch phase. We are not selling anything yet. Instead, we are identifying a small group of prospective partners who are actively working with AI research tools to refine our product based on real-world usage patterns.\n\nYour profile suggests a strong fit for this early group. We are looking for feedback on how the current research feed integrates into existing workflows. This is not a sales pitch. It is an invitation to test the core functionality of the Substrate Layer tool, which is free to access during this launch window.\n\nIf this aligns with your current priorities, reply with \"Interested.\" I will send a direct link to the tool and a one-page overview of the data structure. No commitment required.\n\nIf this isn’t relevant right now, no response is needed.\n\nBest,\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:0686498c8cf88508d706af14af2ffd558dc58caa6d6b92621fd77c04756955c4","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":"sha256:4a840f7b0abe92a031fb92467d785199ffbca269ee7ceeb6e8d80e4aa6726c2d","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:d1380582f03e685eaa2ad2c341201844fc5f1a70f214b6fe92611dbecd7c5af9","anchor":{"event_id":"be9ff82a1b9b120ec394845aa9cebcadb67e4c967ab37b85ad1c7e88c2531bd0","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-20T12:12:21.921Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-20T12:12:21.368Z","evidence_url":null,"receipt_uuid":"c7cd4103-7f20-457f-ae23-84fb55f83e5f","output_sha256":"sha256:ec9a52a335c8969d49e6fb3ab9eefd3a2a75fb48bc3a59bf88cdf2b4fc71d016","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-20T12:12:21.368Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:ec9a52a335c8969d49e6fb3ab9eefd3a2a75fb48bc3a59bf88cdf2b4fc71d016\",\"receipt_uuid\":\"c7cd4103-7f20-457f-ae23-84fb55f83e5f\",\"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":"2026-10-20T12:12:21.368Z","detail":"The receipt store reports 2026-10-20T12:12:21.368Z; 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.
