G-A2600-005 corpus regression audit + acceptance assessment

Concern: With iter 29's chassis fix in place (full-pipeline regen on every prove), validate that G-A2600-005's F8 bank-switching work hasn't broken any non-F8 ROMs in the Atari corpus. Acceptance #4 ("fix applies to any F8-mapped cartridge") needs to hold against the actual lifted output, not the previously-cached output.

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