Linting

• PHPCS: Run npm run lint-php.
• Psalm: Run vendor/bin/psalm --no-cache --diff.
• Before pushing: The pre-commit hook only lints new files. CI lints all changed lines. Always run both PHPCS and Psalm on modified files before pushing to avoid CI failures.

Conventions

• Changelogs: Every user-facing change MUST have a changelog entry before opening a PR. Run npm run changelog (entries stored in changelog/).
