Synchronize used to run folder.synchronize on the UI thread: the import
of the new files, the existence checks and the sidecar reads all made
the window wait. Confirming now only takes the dialog's scan and hands
its SyncWork to a worker thread; the dialog closes at once, a progress
window ("Synchronizing… n / m", Cancel) shows while it runs, the steps
are committed between frames through execute_fn (auto-write, durable
save, panic guard) and the whole run is one undo step, with a toast
saying what was done. Cancel stops before the next piece; what was done
stays. A stale scan is still refused and made again. Headless `busy`
now waits for the scan and the run.

SyncJob::start readies a synchronize from the session without any
file-system call; SyncWork::run does all of the file work (the import's
probes in batches, whether moved and missing files are still as the scan
found them, reading the sidecars) and hands over SyncSteps; SyncCommit
applies each to the catalog without touching the disk and finish()
makes them one undo step. The app runs the work on a worker thread;
folder.synchronize runs the same halves in turn. Progress (done/total)
and cancel go through SyncProgress, one task from start to end.

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.

The import reused the review's probes for every file it had seen, even
one deleted (or rewritten) since: such a file was added as a photo of a
file that isn't there. A cached probe is now used only while the file
is there with the same size (checked in prepare_files, on the import's
worker thread; the web's files keep their probes).

read_sidecar_op = read and parse the packet (file I/O) + sidecar_op
(build the op from what it says). The split lets a worker thread do the
reading while the UI thread only builds and commits the op. No change in
behaviour.

When a stale scan was made again, the dialog came back with the default
choices, so a ticked "Remove missing" or "Read metadata" was silently
dropped before the next click. The choices now carry over. A saved
dialog without `relink_moved` reads it as on, the engine's default.

A scan was current only while the folder's photo records were the very
same; the face search adding regions in the background replaced them,
so confirming could keep failing as stale while it worked through the
folder. A photo now counts as changed only when something synchronizing
depends on changed: its file, its place in the library, or what a
sidecar is compared with (regions aside).

Moved-file matching only knew photos with a content hash, one per hash:
a photo taken over from a Lightroom catalog (no hash on record) that was
renamed still showed as missing with its file as new, so Remove missing
+ Import new swapped it for a bare copy; a Photo › Duplicate (hash
"<h>:dup<id>") never matched; and of two missing files with the same
content only the first was found.
Hashes now match by the content they stand for, each missing file
claiming one file; a photo with no hash matches by file size and
dimensions, only when exactly one missing file and one unclaimed file
agree. A Local record listed as new no longer carries its
"duplicate"/"existing" marks in the scan.

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.

The docs claimed only a sidecar written here before auto-write was
turned off could be mistaken for an update; in fact the library only
knows when a photo came in or was last developed, so any later rating,
label or metadata change made here can be. Says so, with the headless
fixed clock, the sidecar naming fallback and the walk's limits; the
parity row and what's new also cover relinking moved files, Local
files, offline folders and the `disk` guard. Adds the test that a
sidecar the library auto-wrote is never an update.

The dialog's "Scanning… n / m" counted only the files probed, so it
could sit at m / m while the library's photos were still being checked.
SyncProgress counts both halves (its `files.cancel` still stops the
whole scan).

A scan went stale on any catalog change anywhere (a background import,
a rating elsewhere), and folder.synchronize then scanned again inline:
on the UI thread, and acting on results the person never saw. A scan
now stays current while the folder's own photos are the same records
(Session::take_folder_changes compares them by identity). The dialog
asks with `scanned: true`, which refuses a stale scan instead of
redoing it; the dialog then stays open and scans again in the
background. Agents that just call folder.synchronize still get a fresh
scan.
The app dropped session.folder_changes every frame no dialog was open,
so an agent's folder.scanChanges never reached its folder.synchronize
in the running app; it now only lets go of a scan its dialog made.

Highlight reconstruction rebuilds clipped channels from the chromaticity of
unclipped pixels nearby. Three changes to that colour:
- an unclipped pixel counts by its brightness ((m / 0.8 clip)^4, at most 1),
filled coarse to fine by push-pull, so dark wires across a bright cloud no
longer tint it (the iPhone frame of #548 turned cyan at Highlights -100);
- pixels within 6 px of clipping (partly demosaiced from clipped samples, 25 %
greener than the sky on that frame) give no colour unless nothing else does;
- the rebuilt colour is drawn toward neutral at its brightest channel as more
channels clip ((n - 1 + s) / 2, s rising as the next channel nears its clip).
Binned previews keep each channel the mean of its block and mark blocks with a
clipped sample in a mask (develop_binned_masked, reconstruct_masked), instead
of taking the block maximum: one clipped specular sample no longer becomes a
green speckle at 500 px (HUAWEI PRA-LX1, WAS-LX1A). The denoised twin uses the
same mask. Camera-colour fitting keeps the old binning.
RENDER_CACHE_VERSION 26 (adjust at merge).
The steps to merge were counted from the undo history's length, which
stops growing at its 1000-step limit: with a full history nothing merged,
or only the last part was relabelled "Synchronize Folder" while the
import stayed behind it. Session now counts committed steps
(Session::commits) and Synchronize merges by that count.
Once the import is in, a later part that fails is listed in `failed`
instead of aborting with the import left as a separate step.

A file only browsed in Local was counted as already in the library and
silently dropped; it is now new, and synchronizing brings it into the
library, as an import does.
A photo whose file was renamed or moved within the folder showed as
missing while its file counted as a skipped duplicate, so "Remove
missing" sent the photo and its edits to Recently Deleted and imported
nothing. The scan now matches a missing photo's content hash among the
folder's files and lists it as moved; synchronizing relinks it (on by
default, "Relink photos whose file was renamed or moved"), in the same
undo step.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A folder that isn't there (moved whole, or on a disk that isn't
connected) used to scan as "every photo missing", one tick away from
moving a whole disk to Recently Deleted. The scan (on its worker, so an
asleep share never stalls the UI) now reports it as offline and both
commands refuse it; the dialog says so. A whole disk or a folder holding
disks needs `disk: true`, as Remove Disk from Library does; the disk rows
pass it.

scan_with ran the import scan beside the photo checks in a thread scope
on every target; on wasm32 a thread can't be spawned and Scope::spawn
panics, so Synchronize Folder… crashed the web build. There the two run

Right-click a folder (or a disk other than the startup disk) in the
sidebar's Folders section ▸ Synchronize Folder…: the dialog opens at
once and scans on a worker thread (with progress), then offers Import
new photos / Remove missing photos / Read metadata updates with their
counts (Lightroom Classic's defaults: import only). Synchronize runs
folder.synchronize on exactly the scan shown; closing the dialog
cancels a running scan and lets go of the result. New strings are
translated in every shipped language.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The scan waits on the disk, not the CPU, so its two halves now run at
once: the look for new files (which probes on its own threads) beside
the checks of the library's photos (missing file, newer sidecar), which
run on several threads like the import probes do. A cancelled scan stops
checking. Results keep the photos' order.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
folder.scanChanges keeps its result in the session; folder.synchronize
uses it (once) while it is of the same folder and the catalog has not
changed since, so a scan made on a worker thread is not repeated on the
UI thread and files that arrive after the dialog was shown are left for
the next synchronize. Otherwise it scans again.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A scan compares a library folder (and the folders inside it) with the
disk without changing anything: new files (the import scan's duplicate
rules), missing photos (the Missing Photos rule) and metadata updates
(XMP sidecars saved after the photo came in or was last edited here
that say something the library doesn't). It runs without the session
(SyncInput + scan_with) so the app can scan on a worker thread.
folder.synchronize imports the new files in place and, when asked,
moves missing photos to Recently Deleted and reads the updated
sidecars, all as one "Synchronize Folder" undo step. Only folders the
library holds photos in are accepted, never the startup disk.

Rows below the split row use the existing lossy Huffman path; from the split
row on every pixel is a (bits - 4)-bit word: a complete prefix code for the
difference category followed by the top bits of the T.81 extra bits, dequantised
to the centre of the kept bin, with the usual two-left predictor and an
unclamped running value. The rule was derived by black-box analysis of the 11
CC0 samples (all decode to the same samples as the analysis decoder).
The decoder checks that the fixed-rate section ends within the last byte of the
strip (whole rows plus 0..7 padding bits) and otherwise keeps refusing the file
(preview only), so a file that does not follow the rule is never decoded wrongly.

LRC-LIB-LIBFOLDERS lists folder.label and the Set Color Label menu, with
its limits (no filter or sort by folder label; labels don't follow a

Review fixes. folder_records_follow now drops records left at the
destination even when the moved folder carries none, so an unlabelled
folder renamed onto an old path no longer inherits that path's label.
folder.label {label: none} works once the folder's photos are gone (a
label can no longer get stuck); setting a label still needs photos.
Adds tests for both, undo/redo of a labelled move, and labels replayed
from the journal without a snapshot.

heic-rs reconstructs iPhone HEVC tiles bit-exactly (checked against libde265), but
its colour stage was 2-27 code values off libheif on every iPhone photo: it ignores
the HEVC VUI and assumes BT.709 limited range. lightcraft-heif now converts YCbCr
itself (nclx, else VUI, else H.265 defaults; nearest chroma, bilinear for odd clap
offsets, as libheif), inherits tile ICC/nclx on grids, follows libheif's imir axis
and clap rounding, and outputs 16-bit RGB. Measured on 30 real and synthetic
files: within 1 code value of libheif (pillow-heif 1.8 / libheif 1.23).
Also: HEIF header reader for import (no pixel decode), embedded thumbnail for small
decodes, nclx/VUI colour hint (shared CICP mapping with PNG), clear 4:2:2/4:4:4
Unsupported error, Format::not_decodable as the one source of "why not" (import
reports "HEIC/HEIF support isn't included in this build"), `.heif` imports.

folder.label {path, label} gives a library folder a colour label (or
takes it off) as one undo step; only folders the library holds photos in
are accepted. library.folders reports each row's label. folder.rename and
folder.move commit the folder records with the photos' relinks, so the
labels of the folder and the folders inside it go along and undo/redo
carry them back and forth.

Library folders can now carry what the library knows about them beyond
their photos: FolderRecord (for now a colour label), kept in
Catalog.folder_records under the folder's identity (folder_key) and
changed through Op::SetFolderRecord, one undo step. An empty record is
never kept; a path that names no folder is refused.
folder_records_follow builds the ops that carry a folder's records and
those of its subfolders to its new place on rename or move (dropping
stale records left at the destination), so they can be committed with
the photos' relinks. FolderNode reports the label.

C5060WZ, C7070WZ, SP-510UZ, SP-550UZ, SP-565UZ and SP-570UZ files say
uncompressed 12-bit with many strips whose byte counts sum to exactly
width x height x 1.5. main refused them because the 12-bit branch wanted a
single strip, so they fell to "Olympus compressed ORF" and opened
preview-only. The samples are packed MSB-first, the strips hold two fields
(even output rows, then odd ones) with one gap at the seam, and the last row
of the second field sits right after the last strip. Accepted only when all of
that holds exactly. CFA comes from the Exif tag, white balance from maker-note

Export now leaves out only what it must, and its counts are exact:
- A name starting with a byte-order mark is left out. On the first
line, the reader would take the mark for the file's own.
- A synonym in braces is written, since it reads back. An empty
synonym, or one that repeats another in a different case, is
skipped quietly, as the reader would drop it anyway.
- keyword.export counts and checks for Capture One the keywords it
actually wrote, now returned with the text. It used to guess from
the lines, so a name starting with a brace was missed.

Like the other menu commands, Auto-Tag from Tracklog stamped its toast
with a throwaway context whose clock starts at zero. A while into a

The list format can't hold some names. A name in brackets or braces
would read back as a left-out keyword or a synonym. A line break or a
leading space would split it or break the indentation. A keyword nested
deeper than 64 levels won't read back either. These keywords, and those
inside them, are now left out of the file. keyword.export names them as
`unwritable`, and the toast says which.

Reading a list looked each line up in all the lines before it, and
importing looked each keyword up among every photo's keywords: a
40,000-line list into a 20,000-photo library took nearly two minutes.
Both now use an index built once, and the same import takes about a
second.

- Classic Mac line ends (a lone carriage return) are lines: a whole

The File menu (beside the presets) imports a keyword list file

The UI's menu commands made their toasts with a fresh egui context,
whose clock starts at 0, while the app checks a toast's end against its

- `keyword.export {path?}` writes the keyword list file (Lightroom
Classic's format, which Capture One, Photo Supreme and Bridge read),
or gives its text, and names the keywords Capture One's importer

- `keyword.import {path | text}` reads one (Photo Supreme's Formatted

not UTF-8 is refused.

Photo Supreme's Formatted Vocabulary File (Data ▸ Export to Formatted

a file of that shape pins it down; a real export of 118 keywords read
and wrote back line for line. (Photo Supreme reads Lightroom keyword

A smart preview keeps the colour and tone curves the camera-look fit gave it, so a
fit change (#499, #528, #583) left existing previews with the old look. They now
record LOOK_VERSION in the header; an older one is rebuilt from its original when the
library is opened or Build Smart Previews runs, and kept as it is while the original
is offline.
Lightroom Classic's keyword list files (Metadata ▸ Import / Export
Keywords): a keyword a line, those inside it one tab further in, a
synonym in braces on a line of its own under its keyword, a keyword
left out of export in square brackets.
- `Catalog::keyword_list_text` writes the whole tree that way, by name.
- `keywords::parse_keyword_list` reads one: Windows line ends, a
byte-order mark and blank lines are fine; a line it can't read (two
levels down at once, a synonym of nothing, a "|" in a name, nesting
past 64 levels: a file is input) is an error naming its line.
- `Catalog::import_keywords_ops` adds the keywords the library doesn't
have, with the file's attributes and in the library's spelling of
the levels it has; those it has keep their attributes and gain the
file's synonyms. One undo step.
