+## 2026-03-05 - 4.1.17 - fix(tsunpacker)
+use synchronous fs operations in tsunpacker to avoid readdir race conditions
+
+- Replaced async fs.promises.readdir/rename/rm/rmdir loops with fs.readdirSync/renameSync/rmSync/rmdirSync
+- Removed readdir retry loops that attempted to handle partial/stale readdir results
+- Updated comment to document rationale: avoid race conditions under signal pressure and XFS metadata lag
+- Note: function remains async but now performs blocking sync filesystem calls which may block the event loop during unpack
+
 ## 2026-03-05 - 4.1.16 - fix(mod_unpack)
