Module constants 

On-chain protocol constants matching polygon.move:31-42. These are HARDCODED — no Config struct, no runtime parameters.

Constants

AREA_DIVISOR

Divisor to convert twice_area_fp2 to whole square meters: 2 * SCALE^2.

MAX_PARTS

Maximum number of convex parts per polygon.

MAX_VERTICES_PER_PART

Maximum vertices per convex part (admin-configurable on-chain, here hardcoded to protocol default).

MAX_WORLD

Maximum world coordinate (Earth circumference in Web Mercator, scaled).

MIN_COMPACTNESS_PPM

Minimum compactness ratio in parts-per-million for isoperimetric validation. Formula: 8_000_000 * twice_area >= MIN_COMPACTNESS_PPM * L1_perimeter^2

MIN_EDGE_LENGTH

Minimum edge length in fixed-point units (1 meter).

MIN_EDGE_LENGTH_SQUARED

Minimum edge length squared (used to avoid sqrt). 1_000_000^2.

SCALE

Scaling factor: 1 meter in fixed-point space (= 1_000_000 units).
