Invite-only v0 · BYOK

Turn a plain-language RWE question into an audit-ready study package.

Protocol, statistical analysis plan, table shells, decision log, audit trace, and SAS / R / Python code — with a human approving every methodological decision at an explicit gate. The engine never guesses, never touches patient data, and never runs on our inference bill: you bring your own API key.

Every choice is cited or gated

No methodological choice ships without a catalog citation, a verified reference, or a human decision. An uncited choice blocks the run.

Generator, reviewer, final QC

A generator can never approve its own work. Reviewer findings become ledgered rework, and final QC blocks release.

Auditable end to end

An append-only ledger records every model call, verdict, and human decision. A broken hash chain blocks export.
