 # Changelog
 
+## 2026-03-05 - 4.1.19 - fix(mod_fs)
+use synchronous rm to avoid XFS metadata corruption when removing directories
+
+- Replaced async fs.promises.rm with synchronous fs.rmSync in removeDirectory to avoid observed XFS metadata corruption affecting sibling entries under libuv thread-pool and signal pressure
+- Retains previous options: recursive, force, maxRetries, retryDelay
+- Adds inline comment documenting the rationale for using a synchronous removal
+
 ## 2026-03-05 - 4.1.18 - fix(mod_compiler)
 add diagnostic logging of output directory states after compilation and after import-path rewriting to aid debugging
