  "purpose": "Per-tx fee (fee_microusd = ceil(base_fee_attodollars_per_gas x gas_used / 1e12)) and payment-lane TPS headroom for a supplied payment mix, against the published TIP-1010 mainnet constants (base fee 2e10 attodollars/gas, 500M gas/block, ~94% payment-lane reservation). Successor to model_tempo_gas_economics (art-107), which predates these constants. Every parameter is declared with its TIP-1010 citation and carried as protocol_version so a base-fee governance change is a data re-pin, never a code change. Does not read /docs/api/rpc (outside Tempo's stable API contract). Fixed-point BigInt math, calculator only, zero egress.",
