bun run check and the fmt script now run Bun's formatter (bun fmt --no-script), which reads .oxfmtrc.json and checks the same 175 files with no differences. The pinned oxfmt stays installed for editors. CI already pins Bun 1.4.4, the first release with bun fmt.

Proof: bun run check exits 0. Format step: 42 ms with oxfmt, 9.6 ms with bun fmt (median of 5 runs).

evals/docs-check was not rerun: the only README change is one sentence about the contributor check command, outside the install and evaluate sections the cases grade. Waived by the maintainer's direction to roll this out.

Summary by CodeRabbit

  • Chores
    • bun run check now uses Bun’s built-in formatter for formatting checks; the other checks remain unchanged.
  • Documentation
    • Updated development instructions to describe the formatting and type-checking commands.
    • The documented minimum Bun version is now 1.4.4.

bun fmt --no-script reads .oxfmtrc.json and checks the same 175 files with no differences. The fmt script and check use it; the pinned oxfmt stays installed for editors. Needs Bun 1.4.4, which CI already pins.
