…labels Restore test_print_calldata_gas_analysis from 7bea56e with improvements: - Add resource counts to Table 3 (1 CU = 2 resources, using Compliance._RESOURCES_PER_COMPLIANCE_UNIT) - Parametrize gas limits in _logMaxCUsTable (dynamic array instead of hardcoded 36M/60M) - Replace cryptic scheme labels (4/16, 10/40, etc.) with descriptive names: Current(EIP-2028), PectraFloor(EIP-7623), Glamsterdam(EIP-7976), FlatRate(EIP-7976-alt) - Add plain-English captions to all tables explaining what each measures - Add pricing scheme reference and Fusaka context (EIP-7935 60M block limit, EIP-7825 per-tx gas cap) to notes Refs #459

test_print_calldata_gas_analysisto measure how many compliance units (CUs) and resources can fit in a block under current and proposed calldata gas pricing schemes.Key results (aggregated proof mode, current EIP-2028 pricing):
Under worst-case Glamsterdam flat rate (64 gas/byte), capacity drops ~46% but still allows 147 CUs / 294 resources per 60M block. Pectra floor never binds for ARM txns (execution gas dominates by 6-20x).
Gas limits are file-level constants (
BLOCK_GAS_LIMIT_CURRENT,BLOCK_GAS_LIMIT_FUSAKA,TX_GAS_CAP_EIP7825) for easy tweaking. The linear model (R^2 = 0.9954 agg, 1.0 reg) is validated with out-of-sample predictions.Full results: https://gist.github.com/jonaprieto/cb1f13d487144a91c7c5244debb21cd7
