- metadata.savePreset / applyPreset / presets / deletePreset: named sets of copyright,
creator, title, caption, place and keywords (text replaces, keywords add; one undo step),
saved with the library; Photo → Metadata Preset (apply, Save Metadata Preset… from the active
photo's copyright, creator and place); Settings → Import applies one to every import
(library.preferences import.metadataPreset).
- stack.split (this photo and those after it become their own stack; single leftovers are
unstacked), stack.moveUp / moveDown; in the Stack menus.

- ↑/↓ over any slider nudge it by ≈ 1/200 of its range (exposure 0.05, most sliders 1,
temperature 50 K; ⇧ ×5), one undo step each; the key doesn't also move the selection.
- ⇧Z picks and moves to the next photo (with ⇧X / ⇧U).
- library.source {kind: missing}: photos whose file can't be found; a "Missing Photos" row
appears in the left panel when there are any (checked every 5 s).
- Loupe context menu: Zoom submenu. Parity: stale rows fixed (compare/survey, per-camera
defaults, paste from previous, capture-time edit).

- library.browse {path, subfolders}: a folder's photos are read in place as "local" photos
(catalog flag, SetLocal op) that only folder views list — not All Photos, albums, date
groups, keyword counts or stats. photo.addToLibrary promotes them; importing the folder for
real promotes instead of reporting duplicates. The browsed folder persists with the view.
- UI: Local section (Pictures, Desktop, Downloads, Home, the browsed folder, Browse Folder…);
folder views get a breadcrumb header (each part opens that folder), Include subfolders and
"Add N to My Photos".
- Renderer: a job that fails (unreadable / missing file) is remembered by slot + key and not
requested again every frame — the grid re-queued it forever (a render loop per broken
file). The loupe says "This photo can't be opened" with the reason; grid cells show "!".
ui.inspect lists pending render slots.
- Headless app.export (MCP, lightcraft-cli run) exports the selection like the desktop app.

- develop.pastePrevious (⌥⌘V): the previously active photo's settings (copy groups) onto the
selection; the session tracks the previous active photo.
- photo.copyMetadata / photo.pasteMetadata {fields?}: title, caption, copyright, creator,
location, keywords.
- Photo Merge with last settings (⇧⌃H, ⇧⌃M, HDR panorama): no dialog, the options of the last
merge of that kind.
- Help → LightCraft Help (F1) opens the docs; F-keys map to native macOS accelerators.
- Parity: stale rows fixed (pet eye, merge submenu/keys, preset on import, profile favourites).

library.devices lists mounted volumes with a DCIM folder (macOS /Volumes, Linux /media and
/run/media, Windows drive letters; LIGHTCRAFT_DEVICE_ROOTS overrides; cached for 2 s).
File → Add from Device opens the import review of a card's DCIM folder, set to copy into the
library.

The before side used plain defaults, so raws lost their import defaults (sharpening, noise
reduction, import preset) in Before/After. It now shows the photo's import state, or a chosen
history step, version or the current settings (beforeAfter.setBefore); View → Before/After
Settings: Copy After's Settings to Before, Copy Before's Settings to After (undoable), Swap,
Reset; History rows: Copy History Step Settings to Before. Crop and orientation always follow
the current settings so both sides line up.

- Built-in export presets (JPEG Small 2048 px, JPEG Large full size, Original + Settings, DNG)
and user presets saved with the library (export.presets / savePreset / deletePreset);
app.export {preset, …overrides} everywhere (desktop, MCP, lightcraft-cli run).
- File → Export with Preset submenu (built-ins, user presets, Custom…); dialog: preset
picker, Save preset, Choose… folder picker, subfolder, if-file-exists (add number /
overwrite / skip), start number, TIFF compression (none / LZW / ZIP); {date} naming token.
- One export_batch for the desktop app and headless MCP (paths, conflicts, sidecars);
ExportOptions::to_json is the exact inverse of from_json.
- ⌘E = Export with Previous (alias); parity: Show in Finder row was stale.

- Resize modes: long edge, short edge, width, height, W x H (either orientation), megapixels,
percent; "don't enlarge" (default on); ppi written to JFIF density / PNG pHYs / TIFF tags.
- Full-size export of a cropped photo now renders the crop at native resolution (it was
upscaled to the uncropped long edge).
- Formats: Original (file copied byte for byte + XMP sidecar with the edits, named after the
output) and DNG (raw photos re-encoded losslessly, edits in the embedded XMP).
- Export dialog: Resize-to dropdown, values, Don't enlarge, Resolution; DNG/Original hide
pixel options.
- lightcraft-cli render goes through the shared exporter (colour space, metadata, ppi) and
takes any app.export option via --opt KEY=VALUE; MCP export schema lists the new params.
- xtask resolves the workspace root at run time (a moved checkout broke ci).

library.importPreview scans/probes (probes reused by the import) and marks duplicates;
library.import gains preset, keywords and albumName and is one undo step; File > Add Photos
opens a review grid (thumbnails, checkboxes, duplicates unchecked), add in place or copy into
the dated Originals folders, batched import with progress; engine + headless tests.

Engine: spot.select / spot.update (move target or source, size, feather, opacity, mode) /
spot.refreshSource (next-best source away from the current one) / spot.delete (selected spot);
spot.add resolves the automatic source (so it has a pin and stays put at every size) and selects
the new spot. Remove tool: pins for targets and the selected spot's source, click to select, drag
to move; Size/Feather/Opacity sliders edit new and selected spots; ⌫ deletes the selected spot
(never the photo), / refreshes its source, [ ] size and Shift+[ ] feather (Masking brush too).
Command tests and headless pointer/keyboard tests.

Settings (Cmd+, / app menu on macOS, Edit elsewhere) with General, Import,
Performance and Interface tabs. App settings (startup view, delete
confirmation, GPU, preview size, filmstrip/grid badges, last library) live in
UiState.settings (ui.json); library settings (raw / non-raw / per-camera
import presets, XMP, thumbnail cache size) go through library.preferences into
prefs.json. Import applies the matching default preset; the photo remembers it
as its import look (unedited; Reset returns to it). Open Library… switches
libraries at runtime.
View modes: F full-screen preview (photo on black, arrows step, I cycles the
info overlay, Esc exits), Cmd+Shift+F window full screen, Cmd+I cycles the
loupe info overlay (off / file + date / exposure), Navigator mini map while
zoomed (click/drag pans).

Fix-ups: diagnostic overlays never populate the view-preview cache; Photo Merge's RenderRequest gets
the new overlay field.

Photo Merge's Create Stack option now puts the merged DNG on top of a
collapsed stack of its sources (Catalog::stack_with_ops), so the grid
shows the result; test in tests_merge (and no stack without the option).
Photo Merge dialogs live in a Photo > Photo Merge submenu.

- engine: `merge.hdr`, `merge.panorama`, `merge.hdrPanorama` (bracket size from
EXIF); MergeJob (Send) with progress/cancel, preview renders through the develop
pipeline (deghost overlay, auto-crop frame); finish writes <name>-HDR/-Pano.dng
next to the first source, imports, selects, applies Auto Settings / auto crop
- ui: Photo Merge dialog (HDR / Panorama / HDR Panorama) with live preview on a
worker thread, background final merge with progress toast; context menu and
Ctrl+H / Ctrl+M (Ctrl now means the physical Control key on macOS)
- cli: `merge hdr|panorama|hdr-panorama`, `synth-merge` for synthetic inputs
- merge::synth: procedural brackets (DNG) and panorama views; docs/merge.md

Resolved: album.create (main's one-liner + smart: None), menus (panels in
the Window menu, main's dialog.newFolder ⇧⌘N, app.showInFinder and
app.exportPrevious placed in the menu layout), shortcuts (native-menu skip
+ main's aliases and UI-over-engine rule; Shift+X/Shift+U aliases go
through the culling path; my Shift+P/X/U flag-and-advance dropped in
favour of the aliases). X and Delete stay egui-handled (contextual keys).

Up to 8 OkLCh samples (pointColor.pick samples the colour after the mixer on a proxy render);
per sample hue/saturation/luminance shift, variance (compress/expand the spread around the
sample) and an overall + per-axis range with soft edges, applied after the colour mixer in
ColorOps and its WGSL twin (equivalence case). Indexed control specs
(pointColor.<i>.hueShift …) so develop.set/controls/MCP address each sample. Visualize range
is a render overlay (RenderRequest::overlay) drawn after either renderer: the sample's own
edit is left out and colours outside the range turn grey. Point Color flyout in the Color
section with swatches, eyedropper, sliders, visualize and delete.

Photo.copy_of / copy_name. photo.virtualCopy (Cmd+') clones the photo with
independent settings and history, names it "Copy N" (numbered per master),
adds it to the original's albums and stacks it (expanded) right after the
original; one undo step for several copies (Session::merge_undo). Copies
never write XMP sidecars. "Copy N" badge in the grid, Info panel line,
copy:yes search token. Also: Info panel stars laid out in a row.

Stack entity in the catalog (AddStack/RemoveStack/SetStack ops with
inverses, validation, snapshot + journal replay property test). Helpers
build ops for group (merging stacks), ungroup, remove, set top, collapse,
and stack_with_ops() for future merge results. Views arrange stack members
together and collapse to the top. Commands stack.* (Cmd+G, Cmd+Shift+G, S,
Shift+S, expand/collapse all, stack.auto with preview); grid/filmstrip
count badges (click to toggle), context menu, Auto-Stack dialog.

`media::develop` renders on the GPU when available (views, render_now, exports;
thumbnails stay on the CPU) and falls back to the CPU otherwise. `app.gpu
{enabled?}` toggles it at runtime, `LIGHTCRAFT_GPU=0` disables it for the process,
`ui.inspect` reports the adapter under perf.gpu.
Performance: dropped device buffers are recycled once their thread has submitted
(fresh 100-300 MB allocations per pass cost as much as the passes), Gaussian
passes ping-pong between two buffers and read all channels of a pixel at once,
and long box radii slide over longer chunks. LIGHTCRAFT_PROFILE prints real GPU
stage timings. render_bench prints CPU and GPU columns and the CPU/GPU difference.
24 MP ARW, loaded machine, min of 7: cold loupe 415 -> 32 ms, exposure drag
22-42 -> 3.9 ms, NR drag (1920) 301+ -> 18 ms, export render 1037+ -> 291 ms;
max 1 LSB difference. docs/gpu-pipeline.md describes the implementation.

- engine::import: expand files/folders recursively (sorted; hidden entries
and the library folder skipped), skip known paths, probe + hash in
parallel (std::thread::scope), skip duplicates by content hash (against
the library and within the batch), add in place or copy into
<library>/Originals/YYYY/YYYY-MM-DD/ with unique names; one undoable op.
- library.import {paths, mode: add|copy, album?} returns
{imported, duplicates[{path, existing, reason}], failed, scanned}.
- probe_bytes records the content hash (SipHash-1-3 128) on every photo.
- system clock for import/edit times on native (Session::with_system_clock).
- app: command-line folders are expanded by the engine (re-importing the
same folder is a no-op); example gen_photos writes procedural test JPEGs
(never committed).
- Measured (200 procedural 2000 px JPEGs, M-series): import 2.25 s; reopen:
library load 1.7 ms, control ready 0.12 s, first thumbnail 0.17 s,
visible grid drawn 0.48 s (thumbnails from the disk cache).

- catalog: Store trait (FsStore: temp+fsync+rename+dir fsync; MemStore),
Journal: CRC-checked JSON-lines op log with sequence numbers + atomic
snapshots; torn final record dropped and truncated, stale records after a
snapshot skipped, mid-log damage preserved as catalog.log.damaged-N.
- PushHistory op so each edit logs one history step (not the full history).
- engine: Session::open_library/persist/close_library; every top-level
command is fsynced before returning; presets.json + view.json;
library.info / library.compact commands.
- app: default library ~/Pictures/LightCraft Library (LIGHTCRAFT_LIBRARY or
--library DIR override), --memory for throwaway sessions, snapshot on quit.
- tests: proptest replay(log)==state with random snapshots/reopens, every
truncation of the last record, stale log, mid-log damage, FsStore, engine
restart without close.
