Announces Verifiable Work Layer for AI, Enabling Auditable Byte‑Savings**  \n\n**SAN FRANCISCO, CA – Oct. 14, 2026** – Zambo, the platform that records AI‑generated work as immutable receipts, launches a production‑ready layer that proves saved computational bytes remain unchanged. The service goes live today and is immediately accessible via the Zambo dashboard. By attaching a cryptographic receipt to each optimization, teams can verify that reductions in data size do not alter original content.\n\nThe new layer integrates the ProvibeCode audit tool, offering a free “teaser” scan of public repositories and a paid Zambo Pass ($29 /mo) for full reports. A receipt from a recent audit (https://zambo.dev/run/35abb01e-7c42-4366-9da1-277c66a9b033) confirms that byte‑saving calculations are recorded without claiming correctness. Likewise, Signal’s trust‑passport lookup (https://zambo.dev/run/bc9e1bb0-d049-40c1-a6d2-b54583d92cf4) validates the provenance of the AI agents that performed the work.\n\nZambo’s research module, scored 62 by its internal universal metric, reduces manual synthesis time to 15 minutes. The module’s “fastest win”—a three‑model adversarial debate—generates robust insights in under ten minutes (receipt: https://zambo.dev/run/126b8504-5953-4c3b-bcf0-42156a1d7c51). Matched products such as SUBSTRATE LAYER, PROOFFORGE, and VERIAI can now be certified with a single, auditable step.\n\n“Transparency has been a blind spot in AI development,” said **Dr. Maya Patel, Chief Product Officer, Zambo**. “Our verifiable work layer turns every byte‑saving into a provable fact, letting engineers and stakeholders move forward with confidence.”\n\n**About Zambo**  \nZambo builds the verifiable work layer that records AI actions as cryptographically signed receipts. By turning every computation into an auditable artifact, Zambo empowers developers to certify efficiency, compliance, and trustworthiness across the AI lifecycle.\n\n**Media Contact**  \nLaura Chen, Director of Communications  \nPhone: +1 415‑555‑0198  \nEmail: [REDACTED_EMAIL]  \n\n*Live cryptocurrency prices (BTC $81,769, ETH $2,433.87, SOL $104.61) were retrieved from CoinGecko at 19:28 GMT, Oct 14, 2026 (receipts: https://zambo.dev/run/605e053e-bcf2-45e3-953d-8847a4ab8f54, https://zambo.dev/run/886961e3-6f4a-4662-8ef5-64ec265","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:de57e2dc650baa29bba8dd2b0cc6f3e71afe130c1ea77ff08f9e9a1988b3984f","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:eece4ea553751810e3552963bb19b790c66e62c041706ec55f8498fb07d4cca7","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":"sha256:56f04f2ba64e2155b6d078762c88bdbc267de13264ccc9ee38c458bc9ac0d601","anchor":{"event_id":"577c546666b8e776923415fd20b0d1f35745e5afd51b391aa08c67558cbaccb9","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-14T19:28:22.567Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-14T19:28:21.999Z","evidence_url":null,"receipt_uuid":"bdb655d9-a1a1-4e05-bf86-e3209b66e87b","output_sha256":"sha256:873dddaa4139c03338f26b599b9809963fa8145f966c7dc353a320043f4a3026","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-14T19:28:21.999Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:873dddaa4139c03338f26b599b9809963fa8145f966c7dc353a320043f4a3026\",\"receipt_uuid\":\"bdb655d9-a1a1-4e05-bf86-e3209b66e87b\",\"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":"2026-10-14T19:28:21.999Z","detail":"The receipt store reports 2026-10-14T19:28:21.999Z; 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.
