Update existing Thumb IWRAM continuation lanes from successful DMA reads and writes before the resumed PC+4 snapshot. Keep channel halfword duplication separate from actual lane accesses. Preserve atomic errors, cold-entry diagnostics, IRQ invalidation, and nominal timing.
Add original DMA matrices and resume regressions; update prior invalidation expectations. Record pinned ares and jgenesis evidence and explicit limits for cross-state history, general open bus, and sub-instruction arbitration.
Validated on Darwin arm64: 939 workspace and 870 core/demo tests per debug/release profile, 39 Python tests, native ROM windows, ten window smoke modes, fmt, clippy, and rustdoc. Public ARM/Thumb/memory/BIOS reports remain identical to the previous results.
