+# ForgeFlow 0.6.1
+
+## Windows source updater reliability
+
+- Fixes the Windows PowerShell 5.1 STARTED-handshake failure caused by replacing an already existing status file with `Move-Item -Force`.
+- Uses `System.IO.File.Replace` with an overwrite-copy fallback for deterministic status persistence.
+- Adds a handshake-only verification mode used by the local bootstrap overlay.
+- Keeps ForgeFlow open when startup cannot be proven and now includes the helper log tail in the visible error.
+- Requires the status `updateId` to match the current request, preventing an old status file from being accepted.
+- Records the actual restart PID after a successful update or rollback.
