- ruff config, offscreen smoke tests for all 7 GUI apps/panels - golden v6 .sras fixtures (complete + 4 truncation variants) generated by the pre-refactor writer, with expected header/frontier JSON - golden geometry fixtures from the pre-refactor _build_scan_params - consistency tests proving current code reproduces the goldens Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Phase 0: assert the pre-refactor implementations reproduce the committed

fixtures. Phase 2 migrates these assertions onto core.sras_format /

core.scan_geometry; the fixtures themselves never change.
