* 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 <[email protected]>
* 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.

AGENTS.md gets a prominent "Never crash" section at the top of the golden
rules (Rule 9 now points to it), docs/contributing.md a short paragraph,
a root clippy.toml lets tests use unwrap/expect/panic/indexing, and the
workspace moves unsafe_code from "deny" to "forbid" (no unsafe exists in
the workspace).
