An off-by-default "Recognise faces" toggle and the face model list in Settings,
with a one-drop install: pick a .onnx (Add a model file…) or drop one on the
window. The engine inspects it (recognised by hash, or described from its
shape), a dialog shows its licence, whether commercial use is allowed, what it
was trained on and what LightCraft had to assume, and Install stays disabled
until "I accept" is ticked. "Get…" opens a model's own page in the browser:
LightCraft never fetches a model itself. A file it cannot use says why.
The models folder is shared by the app, the CLI and the MCP server
(`engine::config`, `$LIGHTCRAFT_FACE_MODELS` overrides `<config>/models`), so a
model installed from one is there for the others. A session has none until a host
asks (`with_default_face_models`), which keeps tests hermetic.
Nothing runs a model yet, and the tab says so. Headless tests cover the whole
flow (the dialog, refusing until accepted, installing, a file it cannot use).

`faces.models.list / inspect / install / remove / select` and `faces.enable`, all
reachable from the UI, CLI, control channel and MCP. Models live in a folder the
host provides (`Session::face_models_dir`): one subfolder each with the model, its
manifest and a record of what the user accepted, plus settings.json.
- install needs `acknowledged: true` (the user has been shown the licence), copies
the file under a .part name, checks the copy's SHA-256 against the original, then
renames; a failure leaves nothing behind.
- ids are validated before they become folder names (and a manifest that disagrees
with its folder is ignored); remove only ever deletes a folder that has a model
manifest. A manifest id can no longer be `.`, `..` or start with a dot.
- inspect describes any .onnx without writing anything; unusable files are an
answer ("unsupported" with the reason), not a crash.
- the list says plainly that running a model is not built in yet.
`faces::synthetic` makes a minimal valid ONNX for tests (and the later self-check).

New L1 crate `lightcraft-faces`, the base of a one-drop model install:
- `ModelManifest` (role, licence with a commercial yes / no / unknown flag and a
plain-language notice, provenance, input preprocessing, output, thresholds)
with strict validation: sizes capped, numbers finite and sane, https-only
addresses, bounded text. A manifest from any source is untrusted.
- `known`: models recognised by SHA-256 (YuNet, SFace, AuraFace v1), with what is
and is not known about their licences and training data.
- `onnx`: a streaming, hostile-input-safe protobuf probe of a model's graph
inputs and outputs. It reads a 248 MB model in about 4 ms and never loads the
weights; truncation at every length and random corruption never panic.
- `suggest`: known hash -> its manifest; an unknown model shaped like a face
embedder -> a draft manifest with the assumptions spelled out; anything else
-> a plain reason it is not supported yet.
- `hash`: streamed SHA-256.
Checked against the real model files with an opt-in test (LC_FACE_MODELS). It
found an old exporter listing every weight as an input, now handled. Running a
model (tract) is not part of this crate yet.

a_window_job_crosses_the_wire_and_renders_the_same_window compared the worker's
CPU render with the engine job's render bit for bit. On a machine with a GPU the
engine job renders there, so the test failed by 1 LSB (on main too); without a
GPU (CI) both run on the CPU. It now checks both sizes and a maximum channel
difference of 3, the bound docs/gpu-pipeline.md documents.

In NRW data version 0104 the u32 at byte 0x20 is the black level in sample units: 200 where the darkest samples of the B700, P950, P1000 and P1100 sit, 0 for the A1000 whose samples reach 0. Used when the maker note has no 0x003d.
Raw-IFD flag 0xf006 = 1 marks RAF samples packed MSB-first into 32-bit little-endian words at any depth; 12-bit files with it (FinePix S1, X-A10, SL1000) were read as an LSB-first stream. Nikon uncompressed 12-bit strips of exactly 1.5 bytes per pixel in a file whose maker note has an NRW data block (COOLPIX B700, P950, P1000, P1100) use the same words in file byte order; without the block (E5700, E8400, E8800) they stay an MSB-first byte stream. Shared unpack_words32_msb and Packing::Words32Msb. RENDER_CACHE_VERSION 15 to 16.
A custom white balance on a raw with a colour matrix (DNGs, and other raws
without a file-local look) re-develops the pixels for the chosen white
through the file's own colour model: lightcraft_raw::color::rebalance
re-evaluates the camera transform at the new white and maps the as-shot
development onto it, so a neutral lit by that white renders neutral and
saturated colours move as the camera's matrices say (DNG spec ch. 6, as
Lightroom does). The decoder passes the colour tags and the white the
pixels were developed for in SourceInfo::camera_color; other photos, and
relative white balances, keep the Bradford adaptation. The eyedropper and
Auto invert the same model (color::neutral_white), so a picked grey card
renders neutral.
The Tint sign is main's (#349): unchanged here. Render cache version 15.

ColorData::baseline_sharpness holds the file's BaselineSharpness (raw IFD
or IFD 0; zero, negative, non-finite or above 16 is ignored) and the DNG
writer writes it back, so a conversion or smart preview keeps it. Merge
outputs leave it unset. Rendering doesn't use it yet.

Read DNG 1.6 semantic masks (SemanticName, SemanticInstanceID,
MaskSubArea; any coding the tile/strip reader decodes, e.g. ProRAW's
lossy-JPEG matte) with lightcraft_raw::semantic_masks, map them onto the
developed image, and carry Apple's sky / portrait / skin / hair / teeth /
glasses mattes in SourceInfo::mattes (SourceInfo is no longer Copy).
Sky, Subject, Background and People components sample them through
orientation, warp (Warp::frame, as geometry.rs) and crop like the image,
so preview = export, instead of the heuristics; files without mattes
render as before. Malformed mask IFDs are skipped, and only the first
MAX_MASKS mask IFDs are decoded, so a file full of them costs bounded
work. The render cache version is bumped once, in the white-balance commit.
The corpus test reads corpus/raw/dng-apple-iphone12pro-proraw.dng, the
name `cargo xtask corpus` downloads it under.

Parse ProfileGainTableMap (DNG 1.6) and ProfileGainTableMap2 (DNG 1.7):
both versions, DNG 1.7 precedence (version 2 in IFD 0, then the raw IFD;
version 1 in the raw IFD, then IFD 0), u8/u16/f16/f32 gains, gamma.
Malformed tags (wrong size, zero or huge grids, non-finite or negative
gains, bad spacing or gamma) are ignored, never allocated for.
Byte order: the specification gives this tag no byte order of its own,
unlike opcode lists, so the payload is read in the file's byte order with
a big-endian fallback; a wrong-order read can't pass the size checks.
The module docs quote the DNG 1.6 "Byte Order" rule.
The map is kept in ColorData, written back by the DNG writer (version 1,
or version 2 when its gamma isn't 1) and dropped from merge outputs, whose
geometry no longer matches the capture's active area. It is not applied
to the render: Lightroom Classic renders Apple ProRAW without it.
Supersedes the parser of #273.
The CC0 iPhone 12 Pro ProRAW from raw.pixls.us joins the corpus.

Compression 52546 tiles and strips decode through jxl-oxide (new
default-on `jxl` feature of lightcraft-raw): bare codestreams and
ISO-BMFF containers, 1 or 3 planes, 8-16-bit integers scaled back
exactly from the codestream's own bit depth, 16-bit floats. Edge tiles
may be coded at their nominal or in-image size. Headers are checked
against the IFD in header-only probing too. A single-chunk JPEG XL
preview IFD (RGB or grey) is offered as the embedded preview.
The decoder's memory is bounded by the tile: 16 bytes per sample (three
times that for a lossy grey tile, which the decoder expands to three
channels) plus 64 KiB; jxl-oxide 0.12 was measured at <= 10.3 bytes per
sample for lossless and <= 13.5 per colour sample for lossy tiles. A
codestream needing more (e.g. extra channels) is an error.
Lossless tiles are checked bit-exact on synthetic CFA and LinearRaw
files (zune-jpegxl as a test-only encoder); lossy tiles are unverified
on a real file.

It replaces the strip under the tree, which could be scrolled out of view
and shifted the rows when it appeared; the header is always visible and
nothing moves.

Dropping on the edge of a row places the album there (album.reorder) with
a line showing where; a folder's middle still means inside. A closed folder
opens only when the drop would go inside it. Sort Contents A–Z and Sort
Albums A–Z (album.sort) appear once a folder is ordered by hand.

Place an album or folder before a sibling of its kind (also in another
folder), or last of its kind, in one undo step; album.sort goes back to
by name for one folder.

Album.order and Op::SetAlbumOrder; album_children lists folders first, then
by place, then by name. Moving an album drops its place and undo restores it.

A folder under the pointer is outlined when the drop is allowed and opens
after resting there; a drop zone under the tree takes an album back to the
top level. The move is album.move, so it is one undo step.

Show a dialog's error and keep it open instead of closing it, open the
folder menu from the triangle too, draw a triangle only on folders that
hold something, reveal even when the section is folded, reuse the
translated Create … labels, and fix a misplaced doc comment.

The dialog.new* commands take the folder to create in, the dialogs
remember it, and the Albums tree opens the folders down to the new row.

- With no window (a mask or point-colour overlay, Visualize Spots, soft
proofing, a window refused for a far read) the loupe renders the whole
frame at the size it is drawn. While a slider drags that meant the
photo's every pixel each draft frame at 1:1 and beyond (24 MP per tick
where 2.5 MP was rendered before #351; mask overlays are on by
default). A drag now drafts at most the canvas size, as the windowed
path does; at rest the zoomed frame is rendered as before.
- The Preview size hint in German, Spanish and Russian; the replaced
'Largest long edge…' text removed from those catalogs.

The desktop app keeps logs/lightcraft.log in its settings folder (#286)
and a failed start names it (#370), but a user still had to find the
folder by hand. The host now hands the UI its log file (Services
.log_file) and Help ▸ Open Log Folder (app.openLogFolder) reveals it
through the existing reveal service: Finder and Explorer select the
file, Linux opens the folder. Off where no log is kept (the web,
--memory, LIGHTCRAFT_NO_PREFS). Translated in de, es, ja, pt-br, ru,
zh-hans and zh-hant; parity row MENU-HELP-LOGFOLDER; What's New and
README note it.
