Test block-level two-dimensional gas accounting under EIP-8037.

Verify that the block header gas_used equals max(block_regular_gas_used, block_state_gas_used) across single-block, multi-block, and mixed-transaction scenarios.

Test Functions Overview

Name	Type	Cases (Amsterdam)	Description
test_base_fee_per_gas_follows_dominant_dimension	blockchain_test	4	Verify the child block's base fee follows the bottleneck dimension.
test_block_2d_gas_boundary_exact_fit	blockchain_test	4	Verify a block is valid when state gas dominates regular gas.
test_block_2d_gas_tx_gas_limit_exceeds_regular_remaining	blockchain_test	2	Verify a block is valid when a later tx's gas_limit exceeds the
test_block_gas_refund_eip7778_no_block_reduction	blockchain_test	1	Verify block gas accounting for SSTORE 0→x→0 refund paths.
test_block_gas_used_call_new_account	blockchain_test	1	Verify block.gas_used includes state gas from CALL creating accounts.
test_block_gas_used_create_tx	blockchain_test	1	Verify block.gas_used includes intrinsic state gas from CREATE txs.
test_block_gas_used_mixed_txs	blockchain_test	2	Verify block.gas_used with mixed STOP and SSTORE transactions.
test_block_gas_used_regular_dominates	blockchain_test	1	Verify block.gas_used = block_regular_gas when state gas is zero.
test_block_gas_used_state_dominates	blockchain_test	4	Verify block.gas_used = block_state_gas when state > regular.
test_cumulative_block_state_gas_boundary	blockchain_test	2	Probe the block state-gas inclusion gate with spill-funded usage.
test_multi_block_dimension_flip	blockchain_test	1	Verify gas_used across blocks where dominant dimension flips.
test_receipt_cumulative_differs_from_header_gas_used	blockchain_test	1	Verify receipt cumulative_gas_used can diverge from header
test_tx_gas_limit_block_boundary	blockchain_test	48	Reject tx whose gas_limit exceeds the block gas_limit.
test_tx_inclusion_at_regular_gas_block_limit_small	blockchain_test	2	Probe the regular-gas inclusion boundary with a small-gas tx.
