C5060WZ, C7070WZ, SP-510UZ, SP-550UZ, SP-565UZ and SP-570UZ files say
uncompressed 12-bit with many strips whose byte counts sum to exactly
width x height x 1.5. main refused them because the 12-bit branch wanted a
single strip, so they fell to "Olympus compressed ORF" and opened
preview-only. The samples are packed MSB-first, the strips hold two fields
(even output rows, then odd ones) with one gap at the seam, and the last row
of the second field sits right after the last strip. Accepted only when all of
that holds exactly. CFA comes from the Exif tag, white balance from maker-note
entries 0x1017/0x1018, black 0. RENDER_CACHE_VERSION 27 (adjust at merge).
Three CC0 raw.pixls.us files of one ILCE-7CR (61 MP) scene: lossless
compressed L and M (subsampled YCbCr) and compressed ARW2. A raw corpus
test pins model, colour-filter layout, black level, white level, as-shot
gains and default crop, and checks that the lossless and compressed
mosaics agree inside the crop (green block correlation 0.9976). An engine
corpus test checks each gets a fitted camera look, not the neutral
fallback. All nine public codings decode and fit (mean dE76 1.59 against
their camera JPEGs).

proxies() fitted the decoded camera JPEG into the sensor proxy's box,
which keeps the JPEG's own aspect and can round a pixel short: an
ILCE-7RM4's 1616x1080 preview, decoded at 384x257, fits a 192x128
profile proxy as 191x128, and collect_pairs rejected the mismatch. So
`lightcraft-cli calibrate` skipped every file from this camera and no
profile could be written.
Resize the JPEG to exactly the sensor proxy's size instead; proxies()
has already rejected references whose aspect differs by more than 2%.
Where fitting already landed on the proxy's size the result is
identical (fit is resize at a rounded size), so working renders don't
change: 34 real ILCE-7RM4 ARWs render bit-identically. On 923 files
from one trip calibrate goes from 0 to 843 accepted.

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.

Quantile matching fits the held-out pixels slightly worse than the conditional-median fit it replaced. On 7 of 1023 archive files (compacts, bridge cameras, early Micro Four Thirds) the look passed the acceptance gates only with the old curve, and the quantile curve lost it. The search now runs with the quantile fit first (all pixels, away from edges, with and without the camera profile) and, only when no look passes, runs again with the earlier conditional-median plus isotonic fit, restored as fit_tone_conditional. The gates are unchanged, so no file loses its look relative to the previous fit, and the quantile curve is used wherever it passes. Tests: the flat-step test stays; a synthetic photo whose JPEG carries per-pixel noise misses the gates with the quantile fit and passes with the fallback, and the order of the two is checked.
crs crop edges are normalized to the stored (unrotated) image, while
LightCraft's crop rectangle lives in the oriented frame. Catalog import
applied them unchanged, so crops on portrait photos (EXIF 6 or 8) landed
along the wrong axes.
Read Lightroom's orientation code (Adobe_images.orientation: AB, BC, CD,
DA and the mirrored BA, CB, DC, AD) and map the rectangle into the
oriented frame with Orientation::map_norm_rect; a mirrored orientation
also mirrors the straighten angle. The code comes from the catalog, so
this works while the originals are still missing at import time.

Lightroom Classic catalogs store the crop edges and straighten angle in
their develop settings but, unlike XMP, never a HasCrop flag. The shared
crs mapper only applies a crop when crs:HasCrop is True, so every crop in
an imported catalog was dropped and reported as unmapped.
Infer HasCrop in the catalog path when any crop field is present. The XMP
path is unchanged: there HasCrop="False" with crop fields means the crop
is switched off.

The per-photo look fitted its tone curve as the camera JPEG's median per
scene-luminance bin followed by isotonic pooling. On lens-corrected, sharpened
JPEGs of busy scenes neighbouring bins disagree by more than the gap between
them, so pooling produced flat steps: 13 of 31 segments on a CC0 Z 6II sample,
flat segments in 9 of 13 fitted Nikon Z / ILCE-7 samples. Each step maps a
range of scene tones to one output tone, which renders as posterised patches
with hard edges (issue #475, also #211, #454), and the conditional medians
flatten both ends of the curve.
Quantile matching (sorted scene quantiles against sorted JPEG quantiles) is
increasing by construction and insensitive to misregistration. On the same 13
files no fit has a flat segment, all still pass the gates, held-out RMS within
0.005 of before. Regression test: a misregistered synthetic JPEG.
The one-strip Sony ARW layout was accepted when the raw strip was 1.00-1.25x width x height bytes. The DSLR-A200, A230 and A350 sample files carry strips of 1.06x, 1.23x and 1.04x, passed that test and decoded as colour noise. Every file that decodes correctly (108 in the test archive) has a strip of exactly width x height bytes, so the layout is now accepted only then; the rest report "Sony ARW version 1 / packed compressed variant" and open from the embedded preview like the A290/A380. Part of #461 (not a decoder). RENDER_CACHE_VERSION 16 -> 19.
Renders a raw's DNG ProfileGainTableMap (Apple ProRAW's local tone mapping)
when the photo's Profile option "Camera local tone mapping" is on
(`profile.camera_local_tone`, off by default: Lightroom Classic renders
ProRAW without it). Built on #427's parser; supersedes the decode-time
applier of the first version of #273.
- raw/gaintable: GainTableMap::gain / evaluator (GainEval) per DNG 1.7.1:
bilinear between tables with edges replicated, input clamp(weights .
(R,G,B,min,max))^gamma in linear ProPhoto after the baseline exposure,
index input x MapPointsN clamped to the last point. Saturating cell
math; maps whose sizes don't match their gains aren't evaluated.
SourcePlacement: where a developed source sits in the active area.
- pipeline/local_tone: the gain per output pixel in the scene-linear
stage, before the white balance, mapped back through the frame (crop,
user orientation, warp) and the EXIF orientation. lin_needs_cpu routes
the stage to the CPU when it's on (CPU and GPU match); lin_key includes
it. SourceInfo::local_tone carries the map from the decoder.
- develop: Profile::camera_local_tone (omitted from JSON when off, so
existing settings and their hashes are unchanged); Profile row checkbox
when the source has a map; translations.
- RENDER_CACHE_VERSION 17. Docs: parity row and What's New as an opt-in.
Off renders pixel-identical to main on two iPhone 15 Pro ProRAWs (12 and
48 MP). On adds ~60-75 ms to the scene-linear stage at 1536x2048 on a
2-core VM, the same for both files (cost follows output pixels).

Samsung SRW raws whose raw IFD (private compression 32769 or 32770) stores the samples uncompressed are decoded from the sensor data: 12-bit samples packed two in three bytes (bit order told apart from the samples; NX5, NX10, NX11 and NX20, NX200, NX210, NX1000, NX1100) and 16-bit little-endian words (EX1, WB2000). CFA layout from the raw IFD's CFAPattern; framing, white balance, black and saturation levels from the maker note (value offsets relative to the note; the vectors are stored offset by its EncryptionKey); a one-direction Exif picture size crops to the centre of the framing; black from dark rows or columns when the file states none; saturation plateau below the stated level wins. Compressed codings (32770 with fewer bytes, 32772, 32773) stay preview only with that reason. srw is imported from folders; SRW takes the file-local camera look. RENDER_CACHE_VERSION 17.
sRAW and mRAW store subsampled YCbCr in a lossless-JPEG frame cut into
slices of whole MCUs. Reuse the subsampled lossless decoder added for
Sony M/S ARW with Canon's per-component sequential prediction, re-chop
the stream into image planes, and convert to linear white-balanced RGB
with chroma gains measured per file against the camera's own IFD2 RGB.
Render cache version 17.
Every demo-photo source load evaluated the procedural scene from scratch. A 24 MP demo
original costs ~200 CPU-seconds (AlpineLake, the photo the Detail tests open), and #323
added ~30 loupe tests that each load it at 1:1, Before and After separately. On the 4-vCPU
FreeBSD VM the ui-egui lib tests went from 1198 s to 3046 s, and the tests' 120 s/300 s
waits expired (loupe windows, fixture thumbnails starved of the shared rayon pool, the demo
detail snapshot).
Demo scene pixels are now generated once per (scene, size) and shared: concurrent loads
wait for one generation (Before/After at 1:1 no longer generate the original twice) and
the most recent results are kept up to half the memory budget. Locally, pinned to 4 CPUs,
the ui-egui lib suite now finishes in 155 s; without the change it had done 231 of 338
tests after 25 minutes.

TIFF raws that describe a full-resolution CFA IFD with DNG's tags (levels, crop, AsShotNeutral) but carry no DNG version tag are read by the DNG reader (RawFormat::CfaTiff, dng::decode_as). RGGB when the file states no CFAPattern. Lossless JPEG scans with a predictor selection value above 7 are rejected with that reason and stay preview-only. .3fr and .fff are imported from folders.
