Summary

Formatting now uses oxfmt instead of prettier. The prettier devDependency (and its aube-lock.yaml entries) is gone; oxfmt is a mise-managed tool.

What changes for contributors

• oxfmt is a new tool in mise.toml and mise.lock; mise install provides it. Its pinned npm lock lives under .mise/locks/oxfmt/, which mise.lock references.
• aubr format:write runs oxfmt "**/*.ts" and aubr format:check (used by aubr lint and CI) runs oxfmt --check "**/*.ts". The file scope is the same as before.
• .prettierrc.json and .prettierignore are replaced by .oxfmtrc.json, produced with oxfmt --migrate=prettier: same options (single quotes, no semicolons, no trailing commas, arrowParens: avoid, 80 columns) and the same ignores (dist/, node_modules/, coverage/). sortPackageJson is turned off so package.json key order is left alone.
• CLAUDE.md describes aubr format:write as oxfmt.

To format by hand: aubr format:write, or oxfmt "**/*.ts".

Formatting differences

None: oxfmt leaves every existing .ts file unchanged with this config, so there is no reformat commit and dist/ is identical (rebuilt with aubr package, no diff).

ESLint has no prettier plugin or eslint-config-prettier, so nothing there needed changing.

Verification

• aubr all (format, ESLint, tests, rollup package) passes and leaves dist/ unchanged.
• aubr typecheck passes.

Note

Low Risk
Tooling-only swap with no application or runtime code changes; main risk is contributors missing mise-installed oxfmt or subtle formatter differences despite equivalent config.

Overview
Code formatting moves from Prettier to oxfmt: the prettier devDependency and its aube-lock.yaml entries are removed, and formatting is supplied by a mise-managed oxfmt tool (mise.toml, mise.lock, plus a pinned npm lock under .mise/locks/oxfmt/0.73.0/).

format:write and format:check (used by lint and the build pipeline) now run oxfmt on **/*.ts instead of Prettier. .prettierignore is dropped; ignores and migrated Prettier-style options live in .oxfmtrc.json (ignorePatterns for dist/, node_modules/, coverage/, and sortPackageJson: false). CLAUDE.md documents oxfmt for aubr format:write.

Contributors need mise install (or equivalent) to get oxfmt; aube install no longer installs a formatter.
