A raw without colour matrices of its own now gets DNG ColorMatrix1/2 and ForwardMatrix1/2 for its model when the model is one of the 52 cameras in rawtoaces-data (Academy Software Foundation, Apache-2.0): 22 Canon, 11 Nikon, 11 Sony, 3 Fujifilm and 5 others, plus the other names its alias list gives (Rebel T3i and Kiss X5 for the EOS 600D; bodies it lists as sharing a sensor). tools/spectral_camera_table.py fits, under Standard Illuminant A and D65, a white-preserving 3x3 to the measured spectral sensitivities over rawtoaces-data's 190 training reflectances and writes crates/raw/src/spectral_table.rs. No number comes from Adobe or from a raw decoder. lightcraft_raw::spectral looks a camera up by Exif make and model; the DNG colour model does the rest. camera_preview::starting_colour takes the first available of: the file's own matrices, a camera profile for the model (fitted to the JPEG for tone), the spectral matrices, the file-local JPEG fit, the neutral fallback. A profiled model whose profile fit fails takes its spectral matrices. White balance stays relative to the as-shot look for every raw without matrices of its own, so Photo::relative_wb and the controls are unchanged; calibrate still pools covered models. Tests: one per precedence step (synthetic), the table's lookup, aliases and DNG shape, and a corpus test of the order on ILCE-7M4 (profile), EOS 5D Mark III and D5100 (spectral), EOS 7D (own fit) and a DNG. The ILCE-7RM2 and GFX100S corpus tests now expect the spectral matrices. Attribution in assets/ATTRIBUTION.md and NOTICE. RENDER_CACHE_VERSION 23. Co-Authored-By: Claude Opus 5.5 <[email protected]>

Notes
- Fonts authored or published by Adobe (Source Sans/Serif/Code, Source Han, …) are not used, even though some are OFL-licensed: the asset rule excludes anything from Adobe. Source Sans 3 was removed on 2026-09-30 and replaced by Inter.
- CJK fonts (BIZ UDPGothic, BIZ UDMincho, Shippori Mincho, Noto Sans CJK SC) are not in this repository. They live in
storytold/craft-fonts, with their licences and attribution in its
ATTRIBUTION.md, and are embedded only in builds made with the optionalCRAFT_FONTS_DIRbuild input (all official releases). Never commit font files here; add new fonts to craft-fonts (craftrulesstandards/fonts.md).
