- gpu: the test modules share one GPU_LOCK, and timing and vector_mask
take it too, so one process drives one wgpu device at a time.
- ui-egui: the wgpu tests in pattern_preview_canvas, adjust_preview_gpu,
marquee_autoscroll and layout_perf take gpu_lock().
- affinity compound_limits: the child process selects its test by the
module path (compound_limits::<name>); with --exact, the bare name
matches no test and the child passes without running the check.
- xtask scorecard reads crates/io/tests/it/corpus.rs.
- Docs and comments name the new test paths and the --test it filters.
embedded_preview_color_space only read the EXIF ColorSpace, but Nikon bodies
write none: they say Adobe RGB only in the maker note (tag 0x001E: 1 sRGB,
2 Adobe RGB). A Nikon NEF with Adobe RGB selected had its JPEG preview read as
sRGB by the colour fit.
When the EXIF does not state a colour space, the Nikon maker note's is used
(the EXIF still wins, a DNG still states nothing, other makers' maker notes
are not read). The maker-note locator in tiffep.rs is shared. A packed Nikon
NEF with the tag joins the hostile-input seeds, and rawinfo prints the stated
colour space.

Seven public-domain files (raw.pixls.us), one per decode path: Canon
PowerShot SX50 HS as CR2 and as its DNG conversion, Nikon D3 uncompressed
NEF, Sony DSC-RX0 cRAW ARW, Panasonic DC-G9 high-res RW2 (10480x7794,
crop 10368x7776), Olympus E-1 with a GRBG CFA, and the Olympus E-5 as
the documented known-unsupported packed-ORF case (still previews).
xtask grows --pixls (single-file downloads, the server redirects
/data/ to /download/), a sha256-verified manifest and a --update-manifest
path; photocraft-raw gains the corpus feature and oracle tests: format,
make/model, sensor size, CFA, black/white levels and the crop are exact,
developing yields the crop in 16-bit RGB, deterministic, with sane
range coverage.
Two real findings already documented by the tests: the PowerShot CR2 and
the RX0 ARW carry no as-shot white balance we read, so the grey-world
estimate brightens those scenes (the same camera's DNG develops blacks
to ~0). Reading the Canon and Sony maker-note WB tags is the follow-up.
* raw: clean-room camera raw decoder and developer (photocraft-raw)
A new standalone crate (no workspace deps, wasm-safe, no unsafe) written
from TIFF 6.0, TIFF/EP, the DNG 1.7 spec, ITU-T T.81 Annex H and published
demosaicing papers:
- Lossless JPEG (LJ92) decoder: predictors 1-7, point transform, restart
intervals, combined Huffman+extra-bits fast table.
- DNG: uncompressed (8-16 bit, packed) and LJ92, strips and tiles, CFA and
LinearRaw, linearization, black level (repeat, deltas), white level,
active area, default crop, ColorMatrix/CameraCalibration/ForwardMatrix
interpolation by CCT, AnalogBalance, AsShotNeutral/WhiteXY,
BaselineExposure, orientation.
- CR2 (LJ92 slices, SensorInfo borders, ColorData as-shot WB, measured
black) and TIFF/EP raws (NEF/ARW/PEF uncompressed or LJ92, incl. Sony
lossless ARW tiles, Nikon/Sony documented black and WB tags).
- Develop: black/white scaling, WB with highlight clipping, bilinear /
Malvar-He-Cutler / AHD demosaic (rayon bands, sequential on wasm),
camera -> XYZ D50 -> ProPhoto, exposure, gamma 1.8, 16-bit, orientation.
- Embedded JPEG preview finder; clear Unsupported errors for CR3, RAF,
ORF, RW2, vendor-compressed NEF/ARW/PEF, lossy/JXL/float DNG, X-Trans.
- Limits checked before every allocation; testgen feature with an LJ92
encoder and DNG/CR2/TIFF-EP writers; round-trip, colour-reference,
truncation and corruption tests.
Registered as a standalone crate in xtask layers.

* io: open camera raws through photocraft-raw (16-bit ProPhoto), preview fallback
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* raw: DNG GainMap opcode, fuzz targets, stress tools; open raws from the apps
- Apply DNG OpcodeList2 GainMap (lens shading, e.g. phone DNGs); report other opcodes.
- cargo-fuzz targets (develop, ljpeg) and a mutation stress example.
- Raw extensions in the desktop/web open dialogs and the batch folder list.
- file.open returns the import notes (how a raw was developed, preview fallback).
- codecs: the camera raw refusal points at photocraft-raw.
