experiment showed that unconditional touching-footprint dissolve can merge
whole urban blocks and therefore must pass the same independent gates before
it can replace native instances.
The compact-roof variant therefore merges a connected group only when it has
at most 12 source footprints and fills at least 55% of its axis-aligned
envelope. Larger or irregular connected groups retain their native instances
and are marked `native_instance_complex_touch_group`. These fixed criteria
prevent administrative row-house chains from becoming one ambiguous detector
box while keeping the experiment deterministic and auditable.
