- core/sras_format.py: THE v6 implementation — create_scan_file (writer, byte-identical to the old one, enforced against the Phase-0 goldens), SrasFile parser with frontier/truncation walk, and zero-copy mmap load_angle/load_row views for multi-GB files - core/scan_geometry.py: ScanPlan/AngleGeometry dataclasses, build_plan (rotated-bbox trig from MainWindow._build_scan_params), travel-limit validate_plan (limits now a StageLimits dataclass, not literals buried in the worker), format_eta + EtaEstimator (bounded deque) - core/config.py: ScanDefaults dataclass replaces the module-import-time dict globals. FIXES: editing any main-window port used to rewrite aui_defaults.json without helios_port, silently reverting the Helios port every time (test_helios_port_survives_partial_update covers it). Also drops the inert laser_freq_hz plumbing — scans always used the LASER_FREQ_HZ constant. - hardware/serial_util.py: shared 8N1 open + scored port enumeration (promoted from t3r_control_panel); helios_laser and the panel use it - sc3_aui_app.py and sras_scan_manager.py migrated onto core (three format implementations down to one); ScanWorker now takes a ScanPlan - tests: byte-identical writer vs golden, frontier over every truncation variant, mmap==eager, geometry vs golden fixtures + invariants, config round-trip. 28 passing.
