The engine repository: a retrieval engine that stores data on object storage and runs SQL, full-text search and vector search over it. One file (a "superfile") is a valid Parquet file with BM25 and vector indexes spliced in; the supertable layer composes many superfiles into a queryable table with snapshot-isolated reads and an atomic-commit manifest.

Both arms see the same files and get the same question. File Tools opens them one by one, the way a model typically does today. Infino searches them through a fast retrieval index, with subagents that take a question in plain English. Questions that send an agent across many files are where they come apart; one answered from a single named file usually comes out level.

The arms answer the same question at once, and each panel settles the moment its own arm finishes.
