Sector-metric engine. Compute the metrics that anchor valuation in specific industries: SaaS (ARR, NRR, magic number, Rule of 40), marketplaces (take rate, GMV multiple), lending (LTV/CAC), and crypto (NVT, Metcalfe). It returns operating metrics, not a valuation; use them as inputs to calculate_market_multiple or calculate_dcf. Methods: ltv: arpu, gross_margin, churn_rate; cac: sales_marketing_expense, new_customers; arr: subscription_values; nrr: starting_revenue, ending_revenue, expansion_revenue; magic_number: net_new_arr, sales_marketing_expense_prior; rule_of_40: growth_rate, profit_margin; take_rate: revenue, gmv; gmv_multiple: gmv, ev_gmv_multiple; retention: retained_customers, starting_customers; trl: market_size, market_share, margin, exit_multiple, trl_discount; break_even: fixed_costs, asp, variable_cost; gross_margin: asp, variable_cost; token: transaction_volume, price_per_tx, velocity, supply; nvt: market_cap, transaction_volume; metcalfe: n, coefficient. Supply exactly one method with its declared inputs (no defaults). An unknown method, a missing input, or an extra field returns an error envelope (code INVALID_ARGUMENT) instead of raising.
