Open data

The entire research ledger, exactly as this site is built from it. If any of it is useful to you — for a paper, a class, a model, or your own scrutiny — take it. It is dedicated to the public domain.

License

All data on this site is released under CC0 1.0 — no rights reserved. You may copy, modify, distribute and use it, including commercially, without asking and without attribution. Attribution is appreciated but not required.

The one thing we ask, in the spirit of the project: if you build on it, keep the chain of provenance intact — a number is only worth what its source is worth.

Format

Files are .ndjson (one JSON record per line) or a combined .json. Claims reference evidence by ID; evidence references sources by ID; challenges reference claims by ID. The schema is self-describing — every record carries its own field names — and the field meanings are documented in the method.
