Real fixes: split over-long functions (lock-decision chain, manual sync, validation, phone verification, status), hoist a dead lazy import, context-manage Xvfb and temp dirs, add encodings, share the silent-failure argv loop. lock_grab_handoff read lock._recovery, which gatelock's LockWindow does not have (its public property is recovery); a contract test now checks every attribute the handoff reads against the real class.

"""HTTP fallback for phone verification: find the app's server, fetch JSON.
|
|
|
|
Split out of :mod:`screen_locker._phone_verification` to keep every file under
|
|
the 250-line cap. Composed back into ``PhoneVerificationMixin`` there, so
|
|
callers see no change.
|
|
|
|
Used when adb cannot reach the phone but it is on the same wifi: the workout
|
|
app serves the same JSON over ``WORKOUT_HTTP_PORT``.
