Builds on the flat HookFeeV2 model: - hook_api.macro: HOOK_API_COST(name, cost, amendment) per API, loaded into the import whitelist and charged per import call in Guard.h - sfHookGasPrice on FeeSettings / SetFee / validations, voted through FeeVote and exposed in server_info, ledger streams and validations - hook_gas_price config knob (FeeSetup) and genesis FeeSettings value - hookCostToFee(view, cost) prices cost units with the ledger's gas price - jtx Env applies features before the app is built so genesis FeeSettings see them; hash-order dependent tests updated accordingly
