An X-T30 RAF shot in Acros embeds a black-and-white camera JPEG, so the
per-file look fits only the tone curve, and the colour came from the
neutral "camera RGB ~ sRGB" fallback: a grey sky and muted colours. The
raw decode (lossless compressed) was correct.
Add a hand-kept SAME_SENSOR alias list next to the generated
rawtoaces-data table: the 26.1 MP X-Trans CMOS 4 bodies (X-T30, X-T30 II,
X-Pro3, X100V, X-S10, X-E4) use the X-T3's measured matrices, and their
white balance reads in Kelvin through them.
Photo ▸ Edit In ▸ Open Original in Other Editor handed a photo's stored path
straight to `open` / `xdg-open` / `explorer.exe`, with `Path::is_file()` as the
only check, and Lightroom catalog import kept original paths exactly as the
catalog had them. A crafted `.lrcat` could therefore put `payload.exe`,
`start.lnk`, `run.bat`, `page.hta`, `Evil.app` or `go.command` into the library
and have it run on one user click.
- `lightcraft_engine::open_path`: one gate for every path that leaves
LightCraft for the OS. The extension must be one LightCraft reads
(`import::EXTENSIONS`, which already covers the Edit In copy formats
`tif`/`tiff`/`psd`), it must be a regular file (so a `.app` bundle and any
other folder are out), what a link resolves to must be a read type too, and
what is handed over is the absolute path. A refusal is the sentence shown to
the user.
- Open Original and Edit In go through it; a refused photo is listed in
`skipped` with the reason, and the menu item is greyed out for a record that
can never be opened (extension only, so no disk or share is touched while a
menu is drawn).
- `lightroom_catalog::refuse_non_media` drops such images where the catalog is
read and again where its photos become records, with a warning each, so a
refused entry never becomes an openable library record. A virtual copy of a
refused original goes with it.
Tests: a catalog naming a program (and a virtual copy of it) imports neither
while the catalog's real photos do; a library record naming a program is never
handed to the stub launcher, which records no invocation, and a program
selected beside a photo leaves only the photo, by absolute path. Both fail
before this change.

A DNG whose profile has a LookTable but no ProfileToneCurve (Adobe Standard in
Lightroom-written DNGs) was not tone-fitted and rendered with the near-linear
default tone: flat and ~0.8 EV darker than Lightroom. A look table defines colour,
not tone, and the fit already applies the tables to its proxy. The preview may now
be 10% of the raw's long edge (and 384 px), so Lightroom's 1024 px previews
qualify. Two lossy ILCE-7CM2 DNGs now match Lightroom's mean linear RGB within 3%.
Render cache 65, look version 10.

Lightroom Classic 15.1 writes lossy LinearRaw DNGs (e.g. Denoise output) whose
JPEG XL tiles declare Rec. 2100 primaries with the sRGB transfer curve. These
were rejected ("declared encoding that is not linear RGB") and fell back to the
embedded preview. The tile's samples mean what they would in a lossless tile with
the same header, so the declared curve (sRGB, BT.709, DCI, gamma) is now applied
after the primaries matrix, mirrored and unclipped. PQ / HLG / unknown stay
unsupported.

These files carry no JPEG: their preview is an uncompressed 8-bit RGB
IFD (1217 x 913 in the H4D-40 FFF, 218 x 218 in the CFV 3FR). The
largest such image is handed on by embedded_preview as a small baseline
TIFF, which lightcraft_codecs::decode reads, so 3FR / FFF show a preview
in the grid and loupe before they are developed. No Orientation tag is
written: the raw file's applies, as for JPEG previews without one. The
FFF's 16-bit copy (with a TransferFunction of unknown meaning) is not
used.
decode_raw_preview applied a container-declared colour space by forcing
the JPEG decoder on any owned preview; it now checks for JPEG bytes, so
a wrapped TIFF (or a JPEG XL preview) goes to its own decoder.
Checked on the CC0 H4D-40 FFF and CFV 3FR through
embedded_preview_srgb: right colours, the 3FR upright through its
Rotate90. Tests cover the wrap, the choice among RGB images, a short
strip and truncated files.

An FFF (a 3FR converted on the desktop) has no colour matrix of its own:
the camera's stays in the original 3FR header the FFF carries as a
complete TIFF in private IFD0 tag 0xC51B. The new vendor::hasselblad
reader decodes 3FR / FFF through dng::decode_as and, when the file has
no matrix, takes the matrices from that header, so an FFF no longer
develops with the "camera RGB = sRGB" fallback (H4D-40 as-shot white
moves from xy 0.279, 0.356 to 0.325, 0.336).
RGGB checked against the camera preview on the CC0 H4D-40 FFF and CFV
3FR (raw.pixls.us 931 and 709). Synthetic tests cover the embedded
matrix, an own matrix winning, a missing or damaged header, and
truncated files.

The decoder tried each high-frequency band at its synthesis width and up to
two more columns, keeping the first width whose entropy stream ended exactly.
Two widths can both do that with different coefficients (#899).
Measured on every C-RAW plane in cr3_corpus.rs (CC0 raw.pixls.us files):
each band decodes at exactly one width. A tile with a neighbour on its right
codes bands 5 and 8 (the vertical high-pass of the level-2 and level-1
low-pass columns) at an odd width, so an even band gains one unused column;
no other band is extended. The width now comes from that rule, and a stream
that does not fit it is corrupt (the CR3 falls back to its preview).
All corpus sensor hashes are unchanged. The property-test encoder now codes
bands 5 and 8 the same way. Middle tiles (three or more C-RAW tiles) follow
the left-tile rule; no public file has one.

The Print dialog's Page section gets Lightroom's Page Options for Single Image
and Contact Sheet: the page number at the bottom right, the print settings line
(sharpening, profile, resolution) at the bottom left, and crop marks at the
corners of each photo. They are `print.set {page: {pageNumbers, pageInfo,
cropMarks}}`, saved with templates, drawn in the preview and composed into the
PDF; marks and text turn white on a dark page.
The HDR / Panorama / HDR Panorama dialogs now open with the options of the
last merge of that kind instead of the defaults, and those options are kept
in the library's prefs.json (Session::last_merge) so they survive a restart.
"With Last Settings" and HDR for Each Bracket Set read the same store.

Batches 36's doc conflicts kept main's side of rows both sides had touched; for some, main had not changed the row,
so the PR's update was lost. Restored: LR-VIEW-FILMSTRIP (#1482), KEYC-COMPARE (#1491 + #1555), LR-IMP-LOCAL
(#1547 + #1820), LR-LIB-STACK (#1556), gaps 28 (#1555), 2 (#1029) and 23 (#1038), ROADMAP UI/UX (#1038). The
raw-parity by-maker and by-use tables are re-measured with coverage.py (545 verified, ~94% / ~85%).
