test_bal_invalid_hash_mismatch()

Documentation for tests/amsterdam/eip7928_block_level_access_lists/test_block_access_lists_invalid.py::test_bal_invalid_hash_mismatch@87aba1a3.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip7928_block_level_access_lists/test_block_access_lists_invalid.py::test_bal_invalid_hash_mismatch --fork Amsterdam

Test that clients reject blocks where the BAL hash in the header does not match the actual BAL content.

Unlike other invalid BAL tests which corrupt the BAL content while keeping the header hash consistent with the corrupted data, this test keeps the BAL valid but injects a wrong hash into the header via rlp_modifier.
