 # Changelog
 
+## 2026-03-05 - 4.1.16 - fix(mod_unpack)
+handle partial readdir results from signal-interrupted getdents64 when unpacking to ensure sibling removal and nested moves complete
+
+- Loop readdir calls for destination directory until only the source folder remains to avoid partial-listing leftovers
+- Loop readdir calls for nested directory and repeatedly rename entries until the nested directory is empty
+- Prevents leftover files and incomplete moves when readdir returns partial results under signals
+
+## 2026-03-05 - 4.1.15 - fix(mod_unpack)
+flatten nested output directory without temporary rename steps to avoid race conditions
+
+- Replace rename-rm-rename strategy with: remove sibling entries in destination, move nested source entries up into the destination, then remove the now-empty nested folder.
+- Avoid creating temporary sibling directories and avoid removing the destination directory to reduce filesystem race conditions and metadata lag issues (XFS/NFS/etc.).
+- Remove removed removeEmptyDirectory helper and stop using FsHelpers.move/removeDirectory in unpack; import and use fs.promises methods (readdir, rm, rename, rmdir) directly.
+
+## 2026-03-05 - 4.1.14 - fix(fs)
+replace execSync and fsync workarounds with atomic async FsHelpers operations to avoid XFS races and shell dependencies
+
+- Removed child_process.execSync usage and shell mv/rm commands in mod_unpack and mod_compiler.
+- Removed syncDirectoryTree and fsync-based workaround from the compiler module.
+- Use FsHelpers.move and FsHelpers.removeDirectory (async rename/remove) for atomic filesystem operations during unpack.
+- Await performUnpack directly and simplify unpack flow to improve portability and reliability on XFS and other filesystems.
+
 ## 2026-03-05 - 4.1.13 - fix(mod_unpack)
 Use child_process.execSync (mv/rm) to perform unpack atomically, replacing async fs operations and logs to avoid ENOENT/partial directory listings on XFS
