FOUR CLEAN BUILDS EXPOSE THE NEXT HARDWARE BOUNDARIES

HYPOTHESIS: exact single-instruction generated-C parity is necessary but cannot establish title correctness until instruction effects cross the real cartridge address transform, dynamic dispatch, raster, controller, and title-route boundaries. A clean checkpoint of the most-broken titles should expose those seams without modifying generated output.

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