 # Changelog
 
+## 2026-03-05 - 4.1.11 - fix(mod_compiler)
+flush directory entries before unpack to avoid XFS delayed-log causing partial readdir results
+
+- Add fs import and call child_process.execSync('sync') before unpacking compiled output to force kernel-level sync
+- Add syncDirectoryTree(dir) to recursively open and fsync directory file descriptors and traverse subdirectories
+- Call syncDirectoryTree on the destination directory before performing unpack to ensure TypeScript writeFileSync entries are committed (prevents partial readdir results on XFS)
+- Errors during directory sync are ignored to avoid breaking normal flow
+
 ## 2026-03-05 - 4.1.10 - fix(unpack)
 use atomic renames to flatten nested output and make unpacking more reliable
