- Convert to DNG / Copy as DNG: the encoded DNG must decode to the same raw
data, then goes through safe_file::write_new_unique (temp file, sync,
read-back, hard-linked to the first free <stem>.dng / -2 / -3 name, never
replacing a file). On failure no DNG is left, the photo is not relinked
and the raw copy is kept.
- Photo Merge writes its DNG the same way.
- Smart previews are written atomically; smart::is_valid (header + complete
JPEG) decides "built", has_smart_preview and the offline fallback, so a
proxy cut short is rebuilt (reported as `repaired`); moving proxies to a
new folder never deletes a good one in favour of a damaged copy and
copies across drives atomically.
Stacked on the #93 branch (shared lightcraft_catalog::safe_file helper).

- lightcraft_catalog::safe_file: one tested helper for crash-safe writes
(temp file in the same folder, sync, rename, folder sync; temp removed on
failure), write_new/write_new_unique that never replace a file and read
the result back, same_file, and a per-thread fault injection for tests.
- engine::originals::OriginalGuard: refuses a write whose target is a
catalogued photo's original or XMP sidecar (by file identity), whatever
the conflict policy or exact path. Used by run_batch (export, Export with
Previous, control/MCP exact paths), ui.render/ui.screenshot paths, merge
previewPath, MCP render_photo/screenshot paths (new query command
export.checkTarget) and lightcraft-cli render.
- The conflict policy now covers an export's sidecars together with the
file (Unique gives both the same free name, Skip skips when either is
taken).
- export::write_file replaces the plain std::fs::write in the desktop app,
CLI, MCP and engine writers; XMP sidecar writes use the shared helper.

Raw variants the decoder can't read yet (e.g. Nikon Huffman-compressed NEF
from a D3200/D5100) silently fell back to the camera's embedded JPEG, so
users edited a JPEG with the camera's picture style (e.g. Monochrome) baked
in without being told.
- catalog: Photo.preview_only (serde default; old catalogs load), set /
cleared by Op::SetContent with an exact inverse; Photo::develops_raw().
- engine: ProbeInfo.preview_only carries the decoder's Unsupported reason
into import, the import review (previewOnly) and catalog.query
(previewOnly); photo.inspect includes it. photo.reload and photo.relink
re-probe and clear/set it when the file decodes (or not) now.
- source_info: a preview-only raw is a rendered source (relative WB scale,
display tone curve) instead of raw:true/5500 K + filmic tone map on a
display-referred JPEG; import uses the JPEG default preset for it; the
Edit panel shows the rendered-file WB sliders.
- UI: "Preview" badge on grid thumbnails, a pill on the loupe, a notice in
Edit and Info (amber caution token, Info icon drawn in code).
- Tests: catalog serde/undo, engine import -> reopen -> reload/relink,
headless UI badge/notice widgets.

- Smart previews (smart.rs): a ~1 MB proxy per photo in the library's "Smart Previews" folder
(the decoded preview-size source, scaled, sRGB-encoded JPEG behind a one-line header). When
a photo's original is missing (an unplugged drive), its source loads from the proxy: the
photo renders, edits and exports at proxy size. library.smartPreviews {discard?},
photo.smartPreview status; File ▸ Previews ▸ Build / Discard Smart Previews; Info shows
"Original offline · editing the smart preview".
- Photo ▸ Duplicate (photo.duplicate): a real "-copy" file with the same settings, metadata,
rating, flag, label and albums; one undo step.

Op::SetContent records a photo's file facts (size, dimensions, content hash; undoable).
photo.reload re-probes the photos' files and, for those that changed on disk, updates them and
drops their cached sources; render keys now include the file's content key, so the grid and
loupe re-render. The app reloads this session's external-edit copies whenever its window
regains focus (with a toast).

photo.editExternal renders the active photo with its edits as a 16-bit TIFF "<name>-Edit.tif"
(Adobe RGB by default; ProPhoto / P3 / sRGB) next to the original, never overwriting, adds it
stacked on top of the original and selects it. Photo ▸ Edit in External Editor (⇧⌘E, as
observed; the export dialog stays on ⇧E) then opens it in the application set in Settings ▸
General ▸ External Editor, or the system default (desktop: open -a / start / xdg-open,
spawned, never waited for).

- Auto versions: leaving an edited photo keeps its settings as an Auto version (when they
differ from its latest version; 20 kept); saved with the library, not an undo step.
- View ▸ Slideshow (⌥⌘↩, `interval`): the photos in view full screen, wrapping; Space
pauses, ←/→ step, Esc ends.
- Photo ▸ Convert to DNG (photo.convertToDng): lossless DNG next to the raw with the settings
embedded; the photo and its virtual copies are relinked (Relink gains an optional format),
originals kept, undoable. Import: Copy as DNG (`dng`) for copy imports.
- A fine grid over the photo while a geometry slider is dragged.
- View ▸ Show Photo Counts; Help ▸ System Info… (app.systemInfo, JSON for agents).
- Native menus: modified Enter accelerators.
- Parity rows refreshed (target / quick collection, auto sync, location rules, bring to front).
