The CLI snapshot test and the headless resize test sent Cmd+Plus to change egui's
interface scale; with the keys handed to View > Zoom they no longer did. A
ui.zoomFactor control request (0.5-3, documented) sets the scale explicitly.

Canon's SensorInfo left border is not where light starts: on every corpus
body 10-36 columns left of it already hold image (EOS 6D: masked columns
0-70, border 84), and the black level was averaged over all of them. The
6D read 2591 instead of 2047 (4 % of the range), so CR2s rendered dark with
crushed shadows; 40D +141, 5DS R +131, 5D Mark II +73. The masked run is
now measured from the data: columns whose mean stays within 1/256 of the
range of the leftmost columns', minus a two-column margin.
Against Lightroom Classic (EOS 6D still life, 2000 px, ΔE00): base 7.63 ->
5.23 (p95 24.7 -> 11.3); mean over 86 edit variants abs 9.13 -> 6.19,
effect 3.09 -> 2.75.

The ORF decoder supplies the as-shot white balance (ImageProcessing
WB_RBLevels) and no colour matrix, like ARW, NEF, RW2, RAF, CR2/CR3, PEF
and SRW, but ORF was left out of camera_preview::file_local_look and the
catalog's relative_wb, so it rendered with the neutral fallback matrix:
flat, grey and dark. It now gets the same guarded fit to its camera JPEG
and white balance relative to the as-shot look. Corpus (held-out RMS
against the fallback, all accepted): E-1 0.126 -> 0.014, E-400 0.087 ->
0.022, XZ-2 0.061 -> 0.023; compressed ORFs still open from their preview.
Against Lightroom Classic (CC0 E-1 kit, 2000 px, ΔE00): unedited render
11.25 -> 8.30; mean over 86 variants abs 12.10 -> 9.48, effect 3.44 ->
2.80. Every other kit's unedited render is byte-identical.

Sensor-clipped pixels are rebuilt at raw decode. The tone map rolls them off to
white at Neutral, so any colour they carry shows only when Highlights, a negative
Exposure or Whites darkens them. They took colour from the nearest unclipped pixel
(dark foliage, lens fringes along branches, pixels demosaiced from clipped samples),
left two clipped channels at their white-balance-scaled clip levels (red or pink),
and were neutral only in camera RGB, not after the colour model (a look fitted to
the camera's JPEG, a camera profile).
- highlight::reconstruct_with: chromaticity only from bright unclipped content away
from edges and from the clip, through a normalised push-pull pyramid; a neutral
estimate blended in where reliable content is scarce at every scale up to a
quarter of the long edge, applied only as far as the pixel lies past the nearest
near-clip unclipped pixels (so a surface still runs into clipping without a
step); clipped pairs keep the estimate's ratio at their clip floors; partly
clipped pixels fade into the clipped neutral on their way from the first channel
clipping to the last; fully clipped pixels become the colour model's neutral.
Pixels without a clipped channel are left exactly as they were.
- engine: the decode colour step as CameraColourModel, with clipped_white, which
keeps the camera's neutral for nearly singular or implausible models.
- Tests in raw (continuity along a ramp through every clip, also as lines 1 to 16
rows thick with no reliable colour, on canvases 32 to 1024 rows), engine
(pipeline renders at Highlights -100, #523's edit and Exposure -2 through the
first clip, over the same sweep; a CC0 ILCE-7RM4 corpus file added to
RAW_SAMPLES) and the GPU equivalence suite.
- Render cache version 27.

High Efficiency NEFs (HE / HE★, Z 8, Z 9, Z 6III, Z f) keep compression
34713 but carry a JPEG XS-based codestream (SOC + CAP, FF10 FF50) and no
maker-note 0x0096 table. They fell through to "Nikon compressed NEF
without a linearization table", so the Preview only notice gave Z f users
no hint why their raw wasn't decoded or that Lossless compressed NEFs work.
Detect the codestream before asking for the table and report "Nikon High
Efficiency NEF" with the workaround. Add a synthetic regression test, CC0
Z f HE + Lossless samples to the corpus (raw.pixls.us) with a corpus test,
and list HE NEF among the format gaps in parity.md and ROADMAP.md.
No decoder: the format has no public specification and the existing
decoders (LibRaw, rawler) are LGPL and derived from Nikon's binaries.
