# Completed Steps
- 2026-10-05: The Chrome end-to-end suite drives the private key export screen
as it drives the recovery phrase screen
([#253](https://git.eeqj.de/sneak/AutistMask/issues/253)): the correct
password shows the key, leaving by the settings gear empties the screen, and
leaving while the password is still being checked never puts the key on it.
The cases use the imported key wallet rather than the HD one. Leaving drops
the address the screen was showing, and an HD wallet's key cannot be derived
without it, so on an HD wallet a late decrypt fails by itself and would never
exercise the check that discards it. The screen cannot yet be opened twice in
one popup session ([#460](https://git.eeqj.de/sneak/AutistMask/issues/460)),
so the cases reopen the popup before the second open.
- 2026-10-05: The StateRecovery screen is driven in a real browser under the
shipped CSP, in both end-to-end suites
([#361](https://git.eeqj.de/sneak/AutistMask/issues/361)). A stored record
