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.
Infino searches the files through a fast retrieval index, with subagents that take a question in
plain English and answer it from the rows they find. A file is cited as its path and line.
The arms answer the same question at once, and each panel settles the moment its own arm finishes.
