[1.1.2] - 2026-08-22

Added

  • Multi-exposure (ME) scanning for OpticFilm 8200i SE (GL128): short and long colour passes with host SNR/IVW merge into the deliverable ScanImage.rgb.
  • MeScanDebug and Scanner.last_me_debug for lab-only bracket planes, fusion stats, and pass alignment shifts (not part of the public ScanImage type).
  • Scan Lab (tools/scanlab/): PyQt6 bring-up GUI (mock or real SE), prescan crop, IR pass, ME tabs, USB log, pcap decode, calib cache controls, and adaptive quiet-drain toggle.
  • docs/negpy-integration.md: integrator guide for scan orientation, ScanImage contract, and NegPy migration notes.
  • Adaptive quiet USB drain default on GL128 (DEFAULT_IMAGE_USB_PACE_S, line-aligned throttle in bulk acquire).
  • tools/audit_me_bracket: bracket TIFF audit; --align reports estimated pass shift and post-align luma residual.
  • Mock scanner tests and expanded geometry / pipeline test coverage.
  • opencv-python-headless in the lab dependency group for ME/IR pass registration in Scan Lab.

Fixed

  • Scan orientation on mirror_x models (8200i SE): left–right correction in ImagePipeline.assemble(); prescan crop no longer applies a compensating X flip.
  • ME shadow colour fringes from short/long misregistration: improved OpenCV phase-correlation alignment (AREA downsampling, ROI refinement), merge guard at misaligned edges, and chunked IVW merge to avoid float32 OOM at 3600+ dpi.
  • High-PPI memory use in the image pipeline (integer oversample sums, chunked host calib / film-base makeup / border clamp).
  • 8200i SE IR scans: correct colour DVDSET handling, flattened green IR plane on ScanImage.ir, grayscale preview in Scan Lab.
  • Scan Lab: crop UI limited to Prescan tab; missing busy_changed worker signal; effective crop status in status bar.

Changed

  • ScanImage slimmed to NegPy-facing fields only (rgb, dpi, device_model, optional ir). ME bracket data moved to Scanner.last_me_debug.
  • ME short/long planes stay linear on the bracket; film-base makeup runs once on the merged deliverable.
  • Non-SE bring-up: short Y travel clamps, USB planar RGB toggle, and SANE-aligned session improvements for experimental models.

Notes for integrators

  • Forward-only orientation fix: scans saved before 1.1.2 may still appear mirrored on disk; rescan if orientation matters.
  • NegPy / other apps: consume ScanImage.rgb / ir as returned; do not apply an extra [:, ::-1] flip or prescan crop mirror compensation. See docs/negpy-integration.md.
  • Breaking: removed ScanImage ME fields (rgb_short, rgb_long, exposure_*, merge_*, align_shift_*). Use Scanner.last_me_debug for bracket inspection.
