Summary

Generating one class runs clearstatcache(), is_dir(), file_exists() and unlink() once per generated rule class, which is wasteful for schemas with many rules. This PR removes that redundant per-class work.

Changes

• src/Schematron/SchematronCompilerService.php
  • The directory setup (clearstatcache(), is_dir(), mkdir()) now runs once per compile() call instead of once per generated class.
  • Removed the per-class clearstatcache().
  • Removed the redundant file_exists() + unlink() pair before file_put_contents() — overwriting already works.
• tests/Schematron/SchematronCompilerServiceTest.php (new) and tests/data/schematron/rules.sch (new fixture)
  • Verify that the output directory is created when missing.
  • Verify generated class files contain the expected validate(), message() and context() code.
  • Verify an existing rule-class file is overwritten.
  • Verify that a non-creatable output path throws a RuntimeException.

Testing

• Full PHPUnit suite passes (composer test); Psalm reports no errors.
• An end-to-end CLI smoke run confirmed class generation and overwrite-on-second-run still work.
