Slot: Maximum Distance to Station (Metres) (linkage_max_distance_to_station_m)

Maximum distance to a station for nearest-station strategies; values beyond this distance get null.

Tier: conditionally_core

Why this slot matters

For nearest-station strategies this cutoff decides whether a distant monitor still counts as "nearby"; beyond it the assignment is meaningless and should be null. Without the cutoff, values assigned from stations tens of kilometres away are indistinguishable from tight matches, silently degrading exposure quality.

In plain terms

Some methods take the reading from the closest measuring station. This is the farthest a station may be from the home before the match is considered too unreliable and no value is assigned.
