SW19 is mostly Merton but partly Wandsworth, and the page said only Merton. The cause was one field doing two jobs: _parent_authority takes the modal authority, which is right for a 301 target and wrong as a statement about where a place is. This is not a corner case. A quarter of viable outcodes (425 of 1,760) and a third of viable towns (263 of 783) cross an authority boundary — Bedford the town spans Bedford and Central Bedfordshire. Place now carries `authorities`, every authority holding at least a tenth of the schools and at least two of them, largest first. parent_authority stays single and unchanged, because a redirect still needs one target. The share threshold exists because GIAS carries postcode errors: EN6 lists two Shropshire schools among fourteen in Hertfordshire, and a bare "any authority present" rule would print those as though they were real. A place too small or too fragmented to clear the threshold still names its largest, so the page never goes silent about where it is.
