kFloorWidth top-level constant

double const kFloorWidth

The floor plan's extent in each axis, independent of entityCount: a site is a fixed physical size, and adding more detail to it raises density rather than growing the plan. Chosen together with kQueryRectHalfSize in query_throughput.dart so a 500k-entity document gives the "~2k visible" rect query the brief's gate row describes without re-deriving that number from a run's actual output.

Implementation

const double kFloorWidth = 60000.0;
