Proactive handover can save a millimeter-wave (mmWave) link before a passing body blocks it, but only if the network knows where the user is. We ask whether the radio units that serve a user can localize it accurately enough from its uplink sounding reference signals. We derive position error bounds that include synchronization and array calibration errors, with and without reflected paths known from a digital twin, and test two estimators in a ray-traced street canyon on held-out scenarios. Three findings stand out. First, with line of sight to both radio units, array calibration, not bandwidth, limits the bound. Second, blockage degrades the line-of-sight-only bound sharply, whereas known reflections keep the map-aided bound low. Third, a simple dominant-path estimator fails where it matters most: its errors grow sharply around blockage, and proactive handover becomes worse than the 3GPP baseline. A map-aided multipath tracker cuts the median error from 12 to 3.7 cm and removes this significant penalty at link margins of 15 dB and above, but does not yet beat the baseline.
