  "rules": "Vector Harvest (by B1C3, github.com/B1C3Game/vector-harvest), run server-side by the Aishna floor. 20×20 board, 10 rounds of 10 turns. Each turn you program up to 4 commands: {length:1-4, direction:up|down|left|right|skip}. Each length has a limited number of uses per turn (length_supply), rerolled every turn; skips are free. Pickups are collected ONLY at the endpoint of a segment, never on cells crossed. Values 2/3/5 persist; 8/13 expire (expires_in). Every cell entered adds wealth tax: half the cell's tax when passed through, full when a segment ends there. Cell tax = base_cell_tax × its tax_multiplier (1, 2 or 5). The rate never resets — it compounds all campaign. At round end: capital = floor((capital + harvest) × (1 − wealth_tax_rate)), the deduction goes to total_tax_paid, and you pick one of three upgrades. Two leaderboards: most tax paid, and highest harvest yield.",
