v1.5.7

What's fixed

• Biometric login stuck in an unrecoverable dead end (Android). Diagnostics from an affected user's Activity Log showed biometric hardware reporting available, but never actually enrolled — meaning every attempt was guaranteed to fail with "no credentials found," regardless of fingerprint quality, with no way back to the setup screen to fix it.
  • PIN unlock now re-offers biometric enrollment once when it's available but was never successfully enrolled (and you haven't already dismissed it), using the PIN you just typed.
  • Enrollment failures are now logged instead of silently swallowed.
  • The "Use biometric instead" button no longer appears on the PIN screen when it's guaranteed to fail.
