- Restored print() output in 6 generator/cosim scripts that ruff T20 had silently stripped, leaving dead 'for _var: pass' stubs and orphaned expressions. Files restored from pre-ruff commit and re-linted with T20/ERA/ARG/E501 per-file-ignores. - Removed 5 dead/self-blessing scripts (compare.py, compare_doppler.py, compare_mf.py, validate_mem_files.py, LUT.py). - Added test_mem_validation.py: 60 pytest tests validating .mem files against independently-derived ground truth (twiddle factors, chirp waveforms, memory addressing, segment padding). - Updated CI cross-layer-tests job to include test_mem_validation.py. - All 150 tests pass (61 GUI + 29 cross-layer + 60 mem validation).
