 An open-source, local-first AI research workbench. Describe a research goal in plain language; scientific AI agents read your files, search the web, run Python and R, and query scientific data sources, then return reports, tables, and figures. Every artifact is stored as an immutable, checksummed version with a **Provenance** record exposing the producing code, referenced inputs, execution history, and environment inventory.
