Mammotion YUKA 3000: Crosses boundary / enters no-go zone after update

What this fault means

The mower crosses a previously reliable map boundary or no-go zone after a software change.

Safety: Stop the mower and follow the manufacturer safety instructions before physical inspection.

Step-by-step checks

1. Stop the mower and verify the map itself has not shifted.
2. Confirm current positioning quality before editing zones.
3. Record firmware/app versions and the exact crossing location.
4. Test a short supervised task after restart/update completion.
5. Only redraw the boundary if the map geometry is actually wrong; otherwise report a reproducible navigation regression.
