The production ordered-write path and TIA beam journal previously disagreed about when a 6507 write became visible. atari2600_bus_write_cycle exposed the mapped write before advancing the bus slot, and the journal stored only a pre-write cycle ordinal.

Raw traces, ROM material, local paths, and personal data are not part of this public record.
