RULE VALIDATION

Officially documented: six per-slot genes, clone inheritance, stronger negative genes, two matching positive neighbours replacing a negative, planter-only breeding and same-type plants.

Calculator model: G/Y/H use 0.6, W/X use 1.0, a donor total must strictly exceed the center, and equal winning totals resolve randomly. Facepunch does not publish those exact numeric values or tie behavior.
