- `DevelopSettings.hdr`: enabled, headroom limit (`max_ev`) and SDR-rendition
offsets (brightness, contrast, highlights, shadows, whites, clarity), with
control specs (`hdr.maxEv`, `hdr.sdr*`) and copied with the Light group.
- `ToneMap::hdr` / `display_hdr`: the SDR curve through the midtones, with
highlights lifted up to `2^max_ev`; identical to the SDR tables at peak 1.
- `OutputDepth::F32Hdr`: unclamped linear output up to the peak. The finish
stage carries the peak through highlight desaturation, gamut mapping,
encoding, curves, grain and LUT profiles; with HDR off every branch is the
SDR code path, bit for bit.
- `settings_for`: every non-HDR render (CPU and GPU) uses the SDR rendition.

preset, background, resize, subfolder, conflict, tiffCompression and
dngCompression were in the export tool's schema (and so passed the new
argument check) but were dropped before reaching app.export.

std::process::exit skipped eframe's on_exit (ui.json, close_library) and the
may_close check, so changes still in memory could be lost on Cmd+Q.

The earlier text quoted the 13 investigation files (held-out RMS within 0.005); the whole CC0 archive shows a worst increase of 0.013 and 7 files that need the conditional-median fallback.
With a CropAngle, Lightroom's CropLeft/CropTop and CropRight/CropBottom
are the top-left and bottom-right corners of the tilted crop on the
stored image, and its angle turns the other way to LightCraft's. The
import treated the edges as an axis-aligned rectangle in the rotated
frame and kept the angle's sign, so straightened crops came out the
wrong shape and size.
Carry the two corners through the orientation and then LightCraft's
straighten rotation (angle = -CropAngle, mirrored orientations flip it
back), using the stored image's aspect from fileWidth/fileHeight. On a
real catalog every one of 223 straightened crops now matches the frame
of Lightroom's export, and the content difference falls to that of
unstraightened crops.
