Compressed RAF sensor arrays verified on 13 Fujifilm bodies (`docs/raf-compression.md`). ILCE-7RM6 ARW6 12-bit codes verified on 8 CC0 files (FF and APS-C, both compression modes). Sony ILCE-7CR (61 MP): lossless compressed L and M and compressed ARW2 samples of one scene in the corpus (black level, default crop, as-shot gains, lossless vs compressed mosaic agreement, fitted camera look), and all nine public codings (also uncompressed, small and APS-C crop) decode and fit. Grow the CC0 corpus per model and test each sample decodes with plausible colour. Nikon CropArea and untagged-preview colour-space regression tests; private Z 8 crop verified; the Nikon D4, which records no CropArea, gets its image area and white level measured on 148 NEFs against the camera JPEG (optical-black stripes and magenta clipped highlights gone). |

An unedited raw's **grid thumbnail is that camera JPEG itself**, so no sensor decode is scheduled behind it (`Session::embedded_thumb_is_final`, `grid::skips_the_real_render`): drawing a 512 px thumbnail used to decode the whole raw — 45 s a photo at 1.2 MB/s, 8.3 GB for a 149-raw folder — and the queue it built delayed the render the user was waiting for; a cached render as stand-in, an edited photo and a raw without an embedded JPEG still render |
