The viewer could only parse v2-v4 headers while the app has been writing v6 for some time — it could not open ANY file the current app produces. It now uses core.sras_format directly (v6 only, per user decision). New core/sras_analysis.py (Qt-free): ChannelCalibration, image reducers, and SawPipeline. sras_viewer.py keeps only Qt. Memory (measured, 92 MB synthetic scan, separate processes): old eager path +305 MB read()+slice-copy+astype+float32 mean new mmap path + 31 MB zero-copy view + mean(dtype=) -> identical DC image; old scaled at ~3.3x file size, new at image size - load_angle() returns a read-only mmap view instead of reading the whole data block, then copying it twice - SAW sweeps keep one scalar per pixel (process_shot_metrics) instead of retaining 5 full arrays x pixel count in a results list - CH1 float32 materializes only for pixels passing the DC mask - matched filter caches the template FFT instead of recomputing per pixel - opening a new file drops every reference to the old one (compute/ template/diagnostic workers used to pin the previous multi-GB mapping) Responsiveness: - 250 ms debounce coalesces spinbox storms into one recompute - grating change is a display-time scalar multiply, not a full FFT rerun - colormap/clim reuse the AxesImage (set_data/set_clim) instead of clf() + rebuilding the colorbar; draw_idle() throughout - SAW diagnostics (21 pipeline runs) and CSV export moved off the GUI thread Also: ragged per-angle geometry is respected (v6 angles differ in rows/ frames), truncated scans show only rows present on disk, dead decimation path and v2 fallback branch removed, scipy added to viewer requirements.
