This page separates what has been done from what is planned.
A working platform: federated model training across institutional nodes, a governed data catalogue and access-request workflow, differentially private aggregate queries with statistical disclosure control, provenance tracking, and a tamper-evident audit trail — with multi-factor authentication and institution-level tenant isolation throughout. See Trust & Security for the full control set.
A single archived cohort, contributed by a partner institution, moved through governance review, curation, and harmonisation — then made available to approved researchers through the platform's controlled environment, with a citable data descriptor publication for the contributing team.
