Every rule book, down to the individual provision.
Full text of official rules across many sports, decomposed to the provision and cited to source. Trace a rule across decades, search the corpus as structured legal-style text, or read an edition as it was published.

Parse coverage is the share of editions decomposed to rule level. Sports at 0% are cataloged with source documents preserved; the nightly pipeline has not reached them yet.
Research layers
A live query API over the SQLite FTS5 index, filterable by sport, series, year range, and unit type, with every result deep-linking into the reader. The index already exists; the query API is next.
Current status →Compare two editions side by side, or step one rule through successive years of a series, keyed on titles across renumbering.
Not yet availableCoded overlays on the text: concepts, coding schemes, and confidence. Overlays never modify the underlying provisions.
Methods & citation →Built for citation.
Every rule node, edition, and series carries a stable identifier, provenance back to the canonical source document, and a copy-stable permalink. See the methods page for corpus construction and fidelity.
