# ForgeFlow 0.10.4

## Permanent packaged updater handshake repair

- Binary and source update helpers now use a Windows PowerShell 5.1-compatible atomic status replacement with a real temporary backup path.
- A deterministic overwrite fallback preserves lifecycle reporting on filesystems that do not implement atomic replacement.
- The binary helper exposes a side-effect-free handshake-only verification mode exercised by the real Windows PowerShell executable during tests.
- existing installations with the defective helper require this one-time installer upgrade; every subsequent packaged update uses the repaired helper automatically.
- Startup failures retain request-scoped status and helper-log evidence instead of collapsing into an unexplained exit-code message.
