SURFRAME

The product is a signed container format (.surx) for queryable datasets with Ed25519 signatures, encrypted columns, and an audit trail, solving undetected edits to training sets, evals and deliverables as they move through vendors, buckets and pipelines. It is for developers, data teams and IT teams in B2B organizations that need to prove which exact dataset trained a model or was delivered. Unlike a SHA-256 checksum that only reports that bytes changed, it names the exact entry modified and proves authorship, and is positioned to complement versioning and storage layers rather than replace them.
