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.
