LR-IMP-FORMATS: uncompressed Leaf MOS is a raw, the Hasselblad Lunar decodes as an ARW (#1275)
An uncompressed Leaf Aptus 22 MOS keeps its 16-bit mosaic in IFD0 (compression 1, BlackIsZero, one sample per pixel) with no Make tag and no CFA photometric, so `probe` returned None and the file imported as a greyscale image of the mosaic. Leaf's data block, tag 0x8606 (LeafData in the ExifTool EXIF tag-name documentation), now marks such an IFD0 as a raw: OtherTiff, preview only with the reason, as the lossless-JPEG MOS already is. A rendered RGB image that kept the block stays an image. The Hasselblad Lunar is a Sony NEX-7 that writes an ARW under Make HASSELBLAD; only SONY files reached the ARW reader, so it opened as its preview. A HASSELBLAD file with Sony's raw coding (an IFD with compression 32767 or the tone-curve tag 0x7010, which no 3FR / FFF has) now goes there and decodes like a NEX-7: black 512, the SR2SubIFD white balance. The Tag2010 white-balance fallback, the one table arw.rs keys by model, takes the body from the maker note's SonyModelID (0xb001) when the file is not Sony-branded. Docs: the Lunar is verified in docs/raw/evidence.tsv (236 verified), raw-parity.md, parity-checklist.md, gaps.md and whats-new.md. RENDER_CACHE_VERSION 61 -> 62: a Lunar's thumbnails were rendered from its preview. Co-Authored-By: Claude Opus 5.5 <[email protected]>

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 |

### Leaf and Hasselblad raws
|
||||
- The Hasselblad Lunar's raws (a Sony NEX-7 inside) now develop from their sensor data with every editing tool,
|
||||
instead of opening as their embedded preview. Photos imported earlier switch over with Photo ▸ Reload from Disk.
|
||||
- An uncompressed Leaf Aptus 22 MOS no longer opens as a dark, colourless picture of its sensor mosaic: it imports
|
||||
as a raw and shows its embedded preview (preview only, with the reason), as the compressed MOS files do.
