Fitted with `lightcraft-cli calibrate` to 144 usable ILCA-99M2 ARWs (of
150, seven shooting days, Standard creative style, DRO Auto) and their
in-camera JPEGs; aggregate colour statistics only.
On 30 withheld photos (profile fitted to the other 120) mean dE76 against
the camera JPEG goes 5.11 -> 4.87; 25 of 30 improve, the worst
regression is 0.24. All 150 photos stay accepted. The public raw.pixls.us
ILCA-99M2 file, not used for fitting, stays accepted (5.57 -> 5.73).
A corpus test checks that this public sample's fit keeps exactly the
built-in profile's matrix and table; the ILCE-7CR test now shares its
body. LOOK_VERSION 5 -> 6, as the profile changes the fit of this model.
Setting up Synchronize Folder, an import review or an import made a table
of every photo in the library on the session's thread before the first
file was looked at, and naming one photo's sidecar worked out who owns
every shared sidecar name in the library. In a library of 3.5 million
photos (`scan_setup_bench`, release, a folder of 500): 5.8 s before a
Synchronize scan, 2.6 s before an import review, 1.7 s before an import,
2.4 s for each sidecar written.
- A scan keeps the library as it is (photos are shared, not copied) and
looks up the files it finds (`library_files`) and the contents it probes
(`library_hashes`) on its own thread.
- An import looks the library up with its first files
(`ImportJob::look_up_library`), from the library and the options as they
were when it was set up.
- The owners of shared sidecar names are worked out for the photos asked
about (`StemOwners::among`): all five callers name only those photos.
- Synchronize Folder names its photos' sidecars in the scan, after it has
seen that the folder is there.
Now 0.9 s, 0.05 s, 0.05 s and under 1 s. What is found, and how sidecars
are named, is unchanged: the tests hold the owners against the table of
the whole library as it was made before, and the key made without
allocating against the key, for every string of up to six of the
characters that decide it.

Conflict in panels/dialogs.rs: keep upstream's PQ/HLG HDR curve choice
and route both labels through i18n::tr. Czech for the new strings:
8 catalog entries (import, missing files, GPU notice, mask overlays),
3 format strings (other editor, identical copies) and the HLG label.

Photos imported before focus points were read got one only through Reload from Disk, which
hashes whole files on the UI thread. Now:
- lightcraft_meta::focus::read_header reads only what the decoder looks at: IFD0 (Make,
Model), the Exif IFD, the maker note's IFD and the focus tags' values (a JPEG: its segments
up to the Exif one), walked round by round and decoded with the whole-file code from a
buffer of the file's length holding just those ranges. Bounded rounds, bytes (2 MB) and
size (1 GB). One 32 KB read per α1 / A7S III ARW; on 109 real files (83 with a point)
it gives the whole-file read's point for every one.
- A background job (crates/engine/src/focus_scan.rs) reads photos with no point from a
supported body (by the stored camera; nothing else is opened), ARW or JPEG, one at a
time in path order, with a "Reading focus points" activity row (Cancel::Flag). The UI's
per-frame focus.pump gives it the face scan's pace (paused while dragging or typing) and
starts it once per library opening. Commits every 200 photos or 3 s as system ops (no
undo step, no sidecar write), only meta.focus, only on photos that still have none at the
same path. "Looked, none" goes to focus-scanned.bin beside the library, headed by the
decoder's tag so a decoder knowing more bodies starts afresh; unreadable files are retried
at the next opening.
- photo.readFocusPoints {ids?, wait?} (Photo > Read Focus Points) runs it on demand.
Measured cold on a 5400 rpm USB drive: 200 α1 / A7S III ARWs in 1.9 s (~100 photos/s,
32 KB each), so 58,796 raws take about 10 minutes instead of re-reading 2.25 TB.
Soft-delete and remove-folder now unstack in the same undo step as Recently Deleted, so leftover members show 1/2 not 3/3. Restore-from-trash does not restack.

`embedded_preview_srgb` (the loupe stand-in and the grid thumbnail of an unedited raw) decoded the
largest embedded JPEG whatever the size asked for: a 512 px thumbnail of a Sony A7R VI ARW decoded
its 9984 x 6656 JPEG (5.6 MB) although the file holds a 1616 x 1080 one (0.3 MB).
`lightcraft_raw::embedded_preview_covering(bytes, min_edge)` returns the smallest of a TIFF-based
raw's JPEGs whose long edge is at least `min_edge` and that is a copy of the largest one: aspect
ratio within 1 % (not a letterboxed thumbnail of another shape) and the same number of components
(not the grey semantic masks of an iPhone ProRAW DNG); else the largest, as `embedded_preview`.
The colour-space handling stays in `decode_raw_preview` (a `covering` argument); an unsupported
raw's editing source and the camera-look fit keep the largest JPEG, so a source never depends on
its size level.
On 120 raws of every make in the corpus at 256 / 512 / 1600 px: wherever the largest JPEG is still
chosen the output is identical byte for byte; where a smaller one is (Sony, Nikon, Panasonic,
Adobe DNG) orientation matches, the size is equal or 1-2 px off, mean difference <= 4.7 / 255.
- Rebased onto #1020: its plan route (`preview_window` -> `planned_preview`) now takes the box size and picks
with `embedded_preview_covering` too, so a TIFF raw read through the sparse plan gets the whole file's JPEG.

Calibration's header runs section.calibration, now a registered command (no menu

Verified on 54 ILCE-7RM6 photos, the CA planes made the render worse: our
demosaic already hides about 70 % of the lens CA (the render shows 0.29x
the raw-CFA CA) while the post-demosaic warp moves R and B by 0.84x the
table, so the corner R/G and B/G CA went from rms 0.032 / max 0.125 px
(off) to 0.052 / 0.219 px (on) at 1440 px; only the 16-35 mm improved.
warp_opcode takes a lateral_ca flag; lens_opcodes passes false, so a Sony
ARW gets the one-plane distortion warp. The CA conversion stays live and
tested (FF and APS-C examples, both lossless corpus files' tables). The
follow-up is to warp the CFA colour planes before demosaic. The doc,
tracker (docs/parity-checklist.md), docs/gaps.md, docs/raw-parity.md and
whats-new say distortion applied, CA parsed and off
by default, vignetting not applied; the one-plane default costs 24 -> 45 ms
in the sample stage at 1920 px (three planes: 112 ms).

Read the autofocus point from Sony maker notes (FocusLocation 0x2027, FocusFrameSize
0x2037, FocusMode 0x201b, AFAreaModeSetting 0x201c, AFTracking 0x2021 and the area mode
used from the enciphered 0x9402 block), for the ILCE-1 and ILCE-7SM3, whose layout was
checked against ExifTool's output on 333 real ARWs. Manual focus, centre-only Multi
reports and unchecked bodies give no point. The box is stored on the upright photo as
Meta.focus (omitted when unknown; no catalog format change), filled at import and by
Reload from Disk.
View > Show Focus Point (Alt+F) draws it in Detail, Compare and Survey through rotation
and crop; View > Zoom to Focus Point (on by default) makes Toggle Zoom centre on it; the
Info panel shows "AF-C · Wide · Animal Eye Tracking". photo.inspect returns meta.focus.
docs/sony-ilce7rm6-lens-corrections.md records the three Sony tables, the
measured conventions with their residuals, the conversion to
WarpRectilinear and its fit gate, the model allowlist and how to extend
it, the measurement method, the verification and the limits.
Verified locally on 54 ILCE-7RM6 photos with four lenses. The corrected
render lines up with the camera JPEG within 0.679 px at 1440 px at the
corners and edge midpoints of the 33 measurable photos shot with
in-camera correction on (up to 17.3 px uncorrected). The 13 controls show
the model's own shift. Every fit passes the 0.25 px gate (margin 0.075).
Lateral CA stays within 0.3 px, but applied after demosaic it raises the
render's corner CA (rms 0.032 -> 0.052 px); the doc and tracker say so.
Its "Two conventions" section sets these conventions next to the
ILCE-7RM4A's (vendor::arw_lens, docs/sony-lens-corrections.md, #498):
on the 34 measurable ILCE-7RM6 photos that formula gives 1.429 / 0.319 px
(max / rms) against 0.596 / 0.143, failing only on the 24-70 GM II and
fitting the 100 mm and 200-600 better; no single unit fits every lens
under either, and what would settle it (Sony On/Off exports of a wide
zoom, more lenses). docs/sony-lens-corrections.md gains a pointer to it.
Tracker rows LR-EDIT-OPTICS-PROFILE (one note for both bodies) and
LR-IMP-CAMERA-COVERAGE in docs/parity-checklist.md, gap 8 in
docs/gaps.md, the lens-profile section of docs/raw-parity.md (lens score
unchanged), whats-new (lossless ARWs now; Compressed / Compressed HQ once
the ARW 6.0 decoder, #625, lands) and the colour-fit follow-up note are

A windowed render dehazes with the whole frame's airlight, estimated on a 384 px proxy of the frame
(`local::frame_airlight`). Every window asked for that proxy again, so every pan of a 1:1 view and every
slider step while zoomed sampled the whole original down to it on the CPU: ~200 ms of CPU on a 64 MP raw.
The proxy (taken before white balance) is now kept for the last 4 (source fingerprint, frame, size); white
balance, the dark channel and the percentile still run on it every time. Same pixels: the GPU window of
`render_bench` is byte-identical.
`optics::fingerprint` indexed the first pixel of an empty image; it now hashes only the dimensions then.
render_bench ONLY=window GPU_ONLY=1 on a 64 MP Sony ILCE-7RM6 raw (RTX 4070 Ti SUPER, 4-CPU quota), CPU time:
pan 208-212 -> 9-11 ms, exposure change 200-204 -> 4 ms, NR change 211-217 -> 13 ms.

Grid thumbnails looked much more denoised than the loupe. `nr_params` sized
the radii from the output's scale relative to the source buffer it was given,
not the original: a 256-px cell drawn from the 512-px thumbnail level used
half the full-size radius on pixels that each average ~23 sensor pixels, and
below 0.4x (0.35x for colour) the radius stopped shrinking at all. The
guided filter's eps (the variance treated as noise) also stayed at its
full-size value although downscaling divides the noise variance by 1/scale²,
so texture in small previews was flattened as noise.
- `SourceInfo::native_long` (filled by the engine from the catalog's photo
size, kept when the decoder supplies its own facts, carried to web
workers) and `Plan::detail_scale` = output pixels per original pixel
(from `px_per_long`, so a crop no longer changes it).
- `nr_params(s, scale)`: radii x scale with no floor, eps x scale². Below
1 px the smallest blur the box Gaussian makes is blended in by the ratio
of variances (`blur::box_sigma`); a fade under 1% skips the filter.
At scale 1 the parameters are unchanged: 1:1 views and full-size exports
render as before. The GPU takes the same parameters.
- RENDER_CACHE_VERSION 63: cached thumbnails are redrawn.
Measured on a 1536x1024 noisy synthetic scene (tests_nr_scale.rs), error
of the preview against the full-size render scaled down, as a fraction of
leaving NR off, luminance NR 50 at preview scales 0.5 / 0.33 / 0.25 /
0.167 / 0.1 / 0.05: before 0.53 / 0.70 / 1.04 / 2.26 / 3.87 / 6.07, after
0.28 / 0.37 / 0.66 / 0.90 / 0.99 / 1.00. A 256-px render from the 512-px
level now matches one from the original (mean 0.07 LSB vs 0.71 before).

Measured against the darkest frame on real ARW brackets, each frame is linear to 1 % up to the clip far from
clipped pixels, but within 2 px of them the +2 EV frame's green reads 3–5 % low: demosaicing interpolates it from
clipped photosites. That frame carries the most weight (k = 4) and those pixels were unclipped themselves, so they
kept it, and bright windows took a magenta tinge.
A frame's weight now goes by its brightest channel within 1 px (3 × 3; wider margins changed nothing more). On two
real interior brackets (ILCE-7M3, 0 / −2 / +2 EV), bright pixels whose green against red and blue is over 10 % below
the darkest frame's, in camera RGB: dining room 0.32 % → 0.08 %, kitchen 2.86 % → 0.28 %. Rendered at −3 EV with
main's colour tags (#1123), window pixels with G < 0.85·min(R, B) go 50 → 3 and 16 → 10 (the darkest frame alone:
2 and 205); most of the visible magenta those brackets showed before came from the missing colour tags. Test: a
bracket whose +2 EV frame has 5 % less green next to its clipped pixels merges without the deficit (fails before:
−1.96 %).

The HDR merge has the same cause as the panorama: its result took the
reference frame's colour tags, and a raw whose white balance is only in the
vendor's multipliers (CR2, NEF, ARW...) has no AsShotNeutral in them.
merge_hdr now takes the median multipliers of all its inputs (the rule of
consensus_multipliers: the mean of the middle two for an even count; missing,
non-finite and non-positive values do not vote) and sets the result's
AsShotNeutral to their reciprocal, as stitch does. With no multipliers (DNG
sources) the reference frame's tags are kept, as before. HdrResult carries the
multipliers so that the brackets of an HDR panorama vote as frames of their own
when the merged brackets are stitched (the engine passes them on).
In the app and the CLI the neutral from starting_colour_tags (#965) is already
there for frames balanced alike, so those renders do not change.
Tests: an HDR merge of raw-style frames gets the median AsShotNeutral (odd and
even counts, missing and unusable multipliers ignored) and the written DNG says
it; without multipliers the reference frame's colour is unchanged.
A raw whose white balance is only in the vendor's multipliers (CR2, NEF, ARW...)
has no AsShotNeutral of its own. Loading a frame dropped the multipliers and
stitch copied the first frame's colour tags, so a panorama of frames that reach
the stitcher without a neutral wrote a DNG with neither AsShotNeutral nor
AsShotWhiteXY, and a viewer had no white to start from (a strong colour cast
until White Balance > Auto).
Frames now carry the multipliers (Frame::wb_multipliers, filled from the decoded
raw; load_frame_with is split so a decoded raw can be tested without a file).
stitch takes the median R/G and B/G of the multipliers of the frames that are in
the panorama (the mean of the middle two for an even count; frames without
multipliers, or with non-finite or non-positive ones, do not vote) and sets the
result's AsShotNeutral to their reciprocal, green = 1. The source's
AsShotWhiteXY is dropped with it: a reader takes it before the neutral and the
DNG spec makes the two exclusive. With no multipliers anywhere (DNG sources) the
first frame's tags are kept, as before.
In the app and the CLI a raw without colour matrices already gets a neutral from
starting_colour_tags (#965). For frames balanced alike the new neutral renders
the same (checked in the engine crate); it differs when the camera balanced the
frames differently: the panorama follows the median instead of the first frame.
Tests: the frame carries the multipliers; the consensus for odd and even counts,
with missing and unusable values; stitching raw-style frames gives the median
AsShotNeutral, ignores frames outside the panorama and leaves the colour as it
was without multipliers; the written DNG, read back with the raw reader, has the
reciprocal AsShotNeutral and the white balance the source's multipliers give.
Held-out and library-wide calibrate runs on real CR3s (calibrate's CR3 /
CR2 input is #1073): profiles change little (R7 2.52 -> 2.57, R6 Mark II
6.12 -> 6.09 mean dE), so none is bundled; notes the CRX adaptive QP
172/175 files that stay preview-only. The catalog test pins that an EOS
R6 Mark II (Exif "Canon EOS R6m2") edits in Kelvin through its measured
matrices and an EOS R7 stays relative.

A Lightroom preset's crs:Look (name, group, UUID, amount; the Look table
in .lrtemplate files) is kept as profile.look and resolved against the
user's imported profiles by name, the group breaking ties. Lightroom's six
basic profiles map to ours; its own creative/camera profiles and profiles
not imported yet are reported per preset. References are resolved again
after profile.import / profile.deleteImported, so profiles and presets can
be imported in either order.

- The two halves of each stream are independent bit streams: they now decode in parallel
(`decode_stream`) instead of one after the other inside each of a tile's 13 streams.
- The vertical inverse 5/3 runs its rows in parallel. The horizontal pass lifts each row in place
(`lift_row`, scratch space reused per thread), rows in parallel, instead of allocating two vectors
per row and copying the result back; a test checks it against the vertical pass, row by row.

- The vertical inverse 5/3 lifts whole rows at once (`inverse_lift` with samples `w` values wide)
instead of gathering each column through a strided iterator and scattering it back: the same
integer arithmetic, sequential memory. The horizontal pass is the same function with w = 1.
- `0^n 1` codes are counted with one `leading_zeros` over the next MAX_DPT + 1 bits instead of bit by
bit (same bits consumed, same errors); each line reserves its values up front.
- Colour reconstruction reads plane rows as slices and runs over rows in parallel (it was one
thread per tile: 4 threads on a full-frame file whatever the machine).
Best of 5 on 4 CPUs, previous and new decoder alternating: ILCE-7RM6 FF HQ 0.56 → 0.46 s,

(docs/arw6-compression.md → Timings). The decoded mosaic is identical (hash of every sample) on
the 8 ARW6 corpus files and 2 private full-frame photos (ISO 100, ISO 12800); the pinned corpus
sums still match.
