On an Intel Mac with an AMD Radeon Pro 5300M the Metal compiler crashes
on candle's mlx_gemm kernel, candle-metal-kernels panics on the compile
error, and the worker reported "the AI model failed unexpectedly" and
loaded the model on Metal again for every next job, so AI masks never
worked there.
The worker now retries a job that fails on the GPU (a panic or a candle
error) once on the CPU, after freeing the model. When that works, the
model stays on the CPU for the session and the job's outcome carries a
notice that segment_poll shows once; when the CPU fails too, the GPU
was not the cause and the next job uses it again. Missing or damaged
model files, render and remote-worker errors are not retried. Only
builds with a GPU path (macOS) retry; LIGHTCRAFT_GPU=0 and
LIGHTCRAFT_GPU_BACKEND=off now keep SAM 3 on the CPU from the start
(lightcraft_gpu::env_off_reason), like AI Denoise and the face models.
lightcraft-segment: Sam3::load_cpu, GPU_BUILD; text_logits returns the
crate's Error so Describe failures are classified like clicks.

Conflict only in docs/parity-checklist.md: the generated summary is
refreshed with `cargo xtask parity --write`, and the Last updated line
keeps main's format with this PR's change note (today's date) instead of
the duplicated note the branch carried. ⌥-drag preview still wins over
AllMasks and the selected mask in view_overlay; overlay kinds 6–9 unchanged.

Rendered at the drawn size, the pipeline itself shrinks the 2560 px preview
source (Mitchell prefilter, then the bilinear sampling pass) before the display
fit shrinks it again. At rest the whole-frame render now asks for no less than
the preview level (the photo's own size if smaller, a user's explicit Preview
size if lower, the texture limit at most): the source is copied 1:1 and shrunk
once, by the Lanczos display fit. Drags still render drafts at the planned size.
On a line-grating chart at Fit this takes 1.8 px bars from 0.83 to 1.00 of their
contrast (1920 x 1200 window), at the cost of a larger settled render.

At Fit the loupe was softer than a good downscale of the same file. Four
resamples stacked up between the source and the screen:
- the render edge is rounded up to a 64 px step, so the texture was drawn up
to ~6 % smaller than its size and the GPU shrank it with 2-tap bilinear
sampling;
- the fitted texture sat on a fractional pixel position, so even at the right
size every screen pixel was averaged with its neighbour (#1831 fixed the
same for 100 %);
- the render box truncated its short side (2560 x 1706 for a 2560 x 1707
source), a slightly anisotropic resample that blurred one axis only;
- the codec's decode-time shrink at 2:1 and more, and SourceRef::Fit, used a
box filter, which halves the contrast of detail near the output's limit.
RenderJob::display_fit shrinks a full-quality render that is larger than its
drawn size to exactly that size with Lanczos-3 on the worker (after the caches
have the full render; drafts untouched; part of the key). The Detail view sets
it for the After and Before renders at rest, and snap_fit_rect draws a texture
that is its drawn size on whole physical pixels. The render boxes round their
short side, and the 2:1-and-more shrinks use Lanczos-3.

With no aspect ever chosen, every crop started free, so the Lock had to
be switched on photo after photo. Nothing chosen yet now means locked to
Original, as Lightroom starts; switching the Lock off once is remembered
as free, and an explicit ratio is remembered as before.

The Pick flag on thumbnails, in Compare, in the loupe and on the Pick
button was the same outline as the button's idle state, so a pick was
hard to tell at a glance. A new filled pennant (`Icon::FlagPickFilled`)
marks a pick wherever a photo's own flag is shown; buttons, filters and
the reject flag keep their outlines.

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's lossy LinearRaw DNGs linearise the sRGB-coded samples with a
cubic MapPolynomial in OpcodeList2; measured against Lightroom's preview, the
declared-curve reading tracks its rendering and the linear one is 3.6 EV dark.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.

tests_folder_drop built widget ids from OS paths (C:\...), but the Folders

The template was copied from a sibling app: it exported a "LightCraft Document"
UTI for PhotoCraft's `.pcraft` extension (MIME `application/x-lightcraft`) and
imported `.psb` (Photoshop Large Document) and `.qoi`. LightCraft reads none of
them, so the declarations only made Launch Services type PhotoCraft documents as
LightCraft's and left `.pcraft` with three claimant apps among the Craft suite.
Remove both `UTExportedTypeDeclarations` and `UTImportedTypeDeclarations`. No
CFBundleDocumentTypes is added: the formats LightCraft opens are already declared
by the system or another app, so adding them is out of scope here.
`packaging/check-app-specific.sh` now parses the template as a property list and
fails if it declares any of those types again, while still checking the required
bundle keys.

On Windows 11, `cargo test --workspace` on main fails 11 tests:
- tests_export::same_folder_as_original_exports_next_to_each_photo built its
expected paths with Path::join (`\`), but export joins the subfolder and
file name with `/` (join_path) on every platform. Expect what export writes.
- tests_folder_drop (8 tests) looked rows up as
`source:libfolder:C:\...`, while the Folders section names them with `/`
(`source:libfolder:C:/...`), so no row was found. Look them up the same way.
- mcp backend::tests::{valid_replies_and_errors_are_preserved,
malformed_replies_are_rejected_without_resending} failed only when the whole
crate ran: the shutdown and one-shot-process tests start a copy of the test
binary, the child can inherit a socket a fake server just accepted, and when
the child exits Windows closes its copy abortively, resetting the test's
connection. A test-only lock keeps socket tests and child-process tests from
overlapping (passes 6 of 6 whole-crate runs, failed 4 of 4 before).

Constrain Crop only applied at render time, and the Crop tool shows the
uncropped view with the stored crop, so in the Crop panel (where the
checkbox is) ticking it or moving a Geometry slider changed nothing.
Session::set_develop now shrinks the stored crop about its centre until it
fits the warped photo when Constrain Crop is turned on, or when an edit
changes the warp (Geometry, Upright, lens corrections, section eyes) while
it is on. A crop edit itself is kept as drawn.

Describe merged the detector's per-instance masks. Those stay near 0 even well inside what they
found: a sky came out about 87 % selected, a volleyball net about 70 %, a person about 94 %.
Two instances that touch both fade out where they meet, so a line showed between people standing
side by side.
- The detector's semantic head is now ported: semantic_projection over the pixel decoder, the
transformers implementation's semantic_seg. It matches the reference to about 1e-3, like the
instance masks. tools/sam3_reference.py writes it and the reference test checks it; older
reference files still pass.
- Each instance found (score above the threshold, as before) takes the semantic logits where it
is the strongest instance and near (above -4). The semantic mask is sure inside and runs on
across the boundary between two instances. Far from every instance nothing changes, so
Describe selects nothing it didn't find before.
On 16 prompts over three photos (a mountain landscape, two gym photos), the median coverage
inside each selection rises, e.g.:
- sky 0.87 -> 1.00
- mountains 0.81 -> 0.99
- net 0.71 -> 0.99
- floor 0.92 -> 1.00
- person 0.94 -> 0.99
Each selection gains 0 to 1.9 % of the photo at its soft rim and loses none.

OPFS lookups turned any exception into "absent", and start-up only logged
other read errors, so a library with an unreadable file opened incomplete
and the next save could overwrite the stored copy. Only NotFoundError now
means absent; when a stored library file or the active-library pointer
can't be read, the library isn't opened, nothing is saved and the window
names the file. An unreadable thumbnail index no longer deletes every
stored thumbnail as unindexed.

Canon EOS R6 Mark II writes its Exif model as 'Canon EOS R6 Mark II', which failed the spectral camera table lookup because the table registers the model as 'EOS R6m2'. Add the alias mapping and regression unit tests in lightcraft_raw and lightcraft_catalog.
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.

With stem naming, `IMG_0001.xmp` is the sidecar of every file of that stem and, in a
folder Lightroom has worked on, it is the raw's. On import the packet was looked up
with the library naming alone, so a TIFF or JPEG arriving beside a raw of the same
name read the raw's packet and took its rating, label, keywords and `crs:` develop
settings (the case radialmonster reported in #92; the read side of a catalogued photo
is #1523).
`ImportStems` ranks the files an import is adding as if they were catalogued already,
in the order `StemOwners` uses for writing: the library's files and the arriving ones
together, a raw first, then the file name in lower case. A file that does not own the
stem sidecar reads only its own `<file>.xmp`, never the sibling's packet. A file that
is not catalogued yet has no id, and the id it draws when the import commits is above
every id in the library, so it loses a tie against a catalogued file; between
arriving files the order they arrive in stands for it.
Folder synchronize and the Lightroom catalog import go through the same function, so
a file arriving there is ranked the same way.
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.
photo.reload decoded every targeted file on the UI thread, so a selection
of raws froze the window until all were read. The command is now split into
plan / probe / apply (engine `cmd::reload`); the app intercepts photo.reload
and probes the files on a worker thread with a cancellable activity row
(kind `reload`, counted progress), applying the result as one undo step.
`wait: true` keeps the old in-place behaviour for agents; CLI/MCP unchanged.
