Metadata for 451 calculator capabilities in the current code candidate, generated from the same registry used by the website. It includes stable IDs, formula versions, risk labels, source review dates, canonical URLs, and indexing decisions.
Research you can inspect and reproduce
We publish the calculation metadata, source trail, method, and limitations behind our research work. Finished artifacts and planned work are labeled separately.
Public artifacts
A public study design for measuring formula agreement, unit safety, boundary handling, and citation support across models. No complete result set or leaderboard is published yet.
STEM and construction toolkits
Reusable teaching and planning materials are on the roadmap. There is no downloadable toolkit or partner case study to cite today.
The evidence chain
- Freeze the source set. Record the public source, publisher, and review date before making a claim.
- Separate derivation from drafting. Formula and unit checks are evaluated independently from explanatory copy.
- Run deterministic tests. Normal, boundary, invalid, precision, and regression cases exercise production calculation code.
- Publish the boundary. Risk labels, limitations, versions, and the absence of human expert review remain visible.
Propose a reproducible project
Teachers, public-interest organizations, and subject publishers can propose a calculator based on a public method. A backlink is never required, and proposals do not imply endorsement or an existing partnership.
