Zambo is live: Proof over promises\n\nWe built Zambo because you deserve receipts, not vague assurances.\n\nYou’ve seen the demos. You’ve read the marketing copy. Now you can verify the work. Zambo executes tasks and generates immutable receipts—cryptographic proofs that specific bytes were saved and unchanged. A receipt doesn’t claim the output is “correct” or “perfect.” It proves the code exists, the data is static, and the action happened as logged.\n\nWe are launching today with two core capabilities:\n\n1.  **Substrate Breakthroughs:** A read-only research feed from our adversarial AI engine. It surfaces 51 distinct lifeforms generating live insights. No manual setup. No data leakage. Just clean, executable research.\n2.  **LeadSignal:** A precision outreach tool that finds source-backed prospects. It refuses to invent leads. If it finds no verifiable contacts, it tells you zero results. No filler. No hallucinated names.\n\nWe ran a test search for web design prospects in Austin, TX. The result? Zero leads. The system reported this accurately and preserved your quota. That is the standard. We prioritize integrity over volume.\n\nYou can audit every run. Click any receipt link to view the exact execution trail. If the bytes don’t match the log, the run failed. We don’t hide failures. We document them.\n\n**Your next step:**\n\nTest the integrity claim yourself. Run a single, low-stakes query through Zambo. Check the receipt. Verify the timestamp and the hash. If the proof holds, you have a tool you can trust in production. If it doesn’t, walk away. We’d rather lose a user than earn a false one.\n\nThe link is in your dashboard. The free tier is active. No credit card required.\n\nRun the test. Check the receipt.\n\nBest,\n\nThe Zambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:8263861f2e83ce707f6a2bd0a9eb9f97e707902e2c5003baa123cf2ff8c43a88","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:eb9b3a59b8cc9f08d642ed68e6d113118ec75c159471386f8023546db2b04ccf","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":"sha256:6365f0ef7d35f720a4a1d020a04574e8b2320b08163284479d31daf6669f3847","anchor":{"event_id":"6f185d37ceaf8145831cac2a271b53bb29320a81ca01fc23a3382be883d7bc44","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-25T22:30:27.118Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-25T22:30:26.546Z","evidence_url":null,"receipt_uuid":"cc4036ba-c61f-4abd-bec8-2a7531d8a426","output_sha256":"sha256:61c5c842af93a1aa68d45b58f9f8ce1208eea04a3d00583cc8799594a23f08b5","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-25T22:30:26.546Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:61c5c842af93a1aa68d45b58f9f8ce1208eea04a3d00583cc8799594a23f08b5\",\"receipt_uuid\":\"cc4036ba-c61f-4abd-bec8-2a7531d8a426\",\"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":"2026-10-25T22:30:26.546Z","detail":"The receipt store reports 2026-10-25T22:30:26.546Z; 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.
