The quarterly cost model

ADR-0008, amended by ADR-0009 (tentative): the quarter's cost lines are signed data; the fee is that cost, less any public donations, split evenly among the paying members and rounded down, the same for every product including Simca Logistics. There is no opening multiple, no 10x limit and no margin on top. It starts high when few share it and falls as members join. There is no launch premium, no surplus and no per-member ceiling, and never a percentage of revenue. The calculator exists as library code with MOCK numbers (currency XXX); a mock model cannot become a price table.
