Profession skill-up colors: Skill passes the hard cap · case 04

Crafting at 300 raises skill to 301.

Member previewVariant 4 · 3 implementations · 8 checks per implementation

Case contract

recipe_levels = [learn, yellow, green, gray]. Skill below learn cannot craft (error "too low"). Per roll (0..99), while skill < 300: chance 100 below yellow (orange), 75 below green, 25 below gray, else 0; the skill goes up when roll < chance and the color is re-evaluated each craft.

Why this case matters

Game economies leak or destroy currency when one crafting or pricing rule is off by one boundary, rounding stage or state update; the defect is observable in exact integer outcomes.

One recorded failure

This sample comes from the broken implementation of a controlled reproducer.
