HYPOTHESIS: BRK behaves as a two-byte interrupt boundary despite its one-byte encoding: it pushes PC+2 high then low, pushes P with B/U set, sets live I, and loads the IRQ/BRK vector from $FFFE/$FFFF through the 6507 bus mirror.
Raw traces, ROM material, local paths, and personal data are not part of this public record.
