The dialog was seeding rotation_deg/shift_mm from self._alignment_result whenever it was non-None, with no way to tell whether that result came from a user's own manual Save or from the automatic Fusion -> Angle Alignment run. The automatic path's translation comes from FFT phase correlation - the exact thing manual mode exists to work around - so opening Manual Alignment after running the automatic pass silently inherited its unreliable shifts on top of the (correct) analytic rotation, reproducing the same scattered-scan symptom under a "manual" label. Manual mode should always start from identity (each angle's centroid already coincides with every other's, per the prior pivot fix) unless the user previously used this same dialog to save their own deliberate translation - which is exactly what the sidecar file already records. Seed exclusively from load_manual_alignment() and drop the self._alignment_result branch entirely; the automatic result is never an appropriate seed for a manual editing session.
