Sony's lossless-compressed raw (Compression 7, e.g. ILCE-7M4) stores
512×512 tiles as LJ92 frames of 256×256 with four components: each
frame sample is one 2×2 CFA cell (top-left, top-right, bottom-left,
bottom-right). The generic TIFF path reads a frame as a row-major sample
stream (DNG's convention), which interleaved each tile's left and right
halves row by row: vertical bands, scrambled CFA, purple cast.
arw.rs now detects the layout from the first tile's frame header and
places the cells itself; other lossless-JPEG layouts keep the generic
path. Component order verified on a real ILCE-7M4 file (green
differences to the diagonal neighbour cell match those within a cell).
RENDER_CACHE_VERSION bumped so cached thumbnails of affected files are
re-rendered.

Each version is a row with a live thumbnail of its look, name, date and a marker when the
photo has exactly those settings. Resting on a version previews it in the loupe (nothing
changes); click restores, double-click renames, right-click: update with current settings,
rename, set as before, delete. Named / Auto tabs with counts.

- library.missing lists photos whose file isn't where the library expects it; photo.relink
points one at its new location; library.findMissing {folder} relinks every missing photo
whose file (same name and size) is somewhere in a folder, in one undoable step. New
Op::Relink: like a rename in the catalog, but undo/redo never move files.
- UI: File → Find Missing Photos…, photo menu → Locate Missing File… (when the file is gone).
- Renderer: a remembered failure is retried once the catalog changes (a relinked file).

- 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.

- Metadata gains alt text, extended description, sublocation, city, state/province, country:
catalog, photo.setMeta, copy/paste metadata, XMP read/write (Iptc4xmpCore AltText /
ExtDescrAccessibility / Location, photoshop City / State / Country), sidecars and export
(place fields dropped with "remove location").
- Info panel: camera card (camera, lens, size · file size, format badge, focal length,
shutter, aperture, ISO), then title, caption, alt text, extended description, copyright,
creator, file name (rename), file path (reveal), captured (edit), place fields, GPS.
- Text fields keep what is typed across frames and save on focus loss (they were rebound to
the stored value every frame). New pencil icon (drawn in code); dates::display_time.

- 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).

- `cargo xtask parity` adds a weighted-completion line (✅ 1, 🟡 ½, out of scope left out) per
tier to the generated summary: 65.7% of 500 in-scope rows (P0 98.5%, P1 79.9%, P2 11.7%).
- ROADMAP: remaining work by package in agent-hours (≈ 295–540; ≈ 75–130 h wall clock with
4–6 agents), effort-weighted completion ≈ 20–30% for full parity, milestone statuses
refreshed, Totals replaced.

File → Add from Device opens the import review of a card's DCIM folder, set to copy into the
library.

Dragging a grid cell drags the selection (the cell joins it, or replaces it when it wasn't
selected); a "N photos" badge follows the pointer, album rows highlight under it, and a drop
adds the photos to the album. Tested end to end with ui.drag.

- The Diagonal crop overlay was offered but drew nothing. Guides are now polylines from one
testable module (panels/crop_overlay.rs): thirds, grid, golden ratio, 45° diagonals, harmonic
triangle, golden spiral; triangle and spiral mirror (view.cropOverlayOrientation).
- While cropping: O cycles the overlay, ⇧O its orientation, A locks the crop's current shape
or unlocks it (crop.aspect "current" / "toggle", no refit). Crop panel lists all overlays.

- By Date: year → month → day rows with counts and disclosure triangles; a row filters by
that date prefix (catalog date_groups now carries days).
- Settings → Import → Metadata: copyright and creator given to imported photos that don't
carry their own (library.preferences {import: {copyright, creator}}), saved with 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.

- File → Add Folder… (file.addFolder {path?}): folder picker → import review, subfolders
included.
- File → Quit LightCraft (⌘Q / Ctrl+Q) off macOS; the native macOS app menu keeps its own.
- Holding ⌥ while painting a brush mask flips Add/Erase for that stroke.
- Control channel: injected pointer/key events now announce their modifiers to egui
(ModifiersChanged, held from button down to the frame after up), so modifier gestures work

A clipped pixel is never valid at full resolution, so its diffused chromaticity was always the
bilinear sample of the half-resolution pyramid level; the full-resolution chroma field (288 MB
at 24 MP) and its fill pass were wasted work. The pyramid now starts at half resolution straight
from the image. Bit-identical to the previous implementation (kept as a test reference over odd
sizes and clipping densities). 24 MP: 319 -> 145 ms isolated; real CR2/ARW loads 0.8-1.1 s ->
0.3-0.5 s under load. Runs on every full-resolution raw load (1:1 loupe, export).

- Engine: export split into prepare_export (session thread, cheap) and PreparedExport::run
(Send: read/decode/render/encode); run_batch with per-photo progress, cancel and collected
errors; export_batch keeps the stop-at-first-error behaviour for scripted calls.
- Desktop: the Export dialog, Export with Preset (menu and context menu) and Export with
Previous run their batch on a worker thread (app.export {background: true}); a progress
panel shows count / file / Cancel; ui.inspect reports export {running, last}.
- Headless: settle waits for a running export; `lightcraft-cli snapshot` finishes it before
exiting. Web keeps foreground exports (downloads are main-thread).

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.

`lightcraft-cli run [--demo | --library DIR | --connect [ADDR]] [--import PATH]… CMD k=v … CMD …`
runs any engine/UI command or control-protocol method (headless, on a persistent library, or
against the running app) and prints one JSON line per command; non-zero exit on failure,
--keep-going, --script FILE|- for JSON lines. Imported photos are selected (first active) so
the chain acts on them; a library's edits are saved for later invocations. Docs: docs/mcp.md,
README.

- 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).

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.

Auto Mask strokes weight each dab by similarity (log luminance + chromaticity) to the pixel under
its centre and are refined by a cross guided filter on log luminance (max-combined, never removing
paint). Local Noise smooths small-amplitude luminance detail (negative boosts it) and calms colour
noise; Moiré blends chromaticity towards a blurred plane (appended to the GPU mask buffer);
Defringe desaturates purple/green casts on edges. Pixel tests per slider and for the edge
constraint, CPU/GPU equivalence cases, Auto Mask checkbox and Moiré/Defringe sliders in the panel.

RenderRequest gains a sample format (OutputDepth: U8 for previews, U16, F32Linear); deep renders
run the per-pixel stage with the exact sRGB curve and return Rendered::deep alongside the 8-bit
image (GPU stays 8-bit: deep exports render on the CPU). Export encodes deep renders: 16-bit PNG and
TIFF, 32-bit float linear TIFF with a linear ICC profile we generate, 10-bit AVIF (YCbCr planes into
ravif). Output sharpening and watermarks work on deep images. ExportOptions.bitDepth with per-format
defaults (TIFF 16-bit, others 8-bit), export dialog bit depth choice (remembered with the last
export), MCP export schema. Tests: a smooth gradient has 1024 levels in a 16-bit TIFF vs 13 in
8-bit, float TIFF decodes to the same light as 16-bit, per-format depth rules, AVIF 10-bit.

The profile encoder packs tags back to back, so the odd-length description of the
"Adobe RGB (1998) compatible" profile misaligned the copyright tag and macOS ImageIO ignored the
profile in PNG iCCP (sips showed none). Tags are re-laid at aligned offsets; already aligned
profiles (sRGB, P3, ProPhoto, Rec. 2020) are byte-identical.

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).

The selected mask's evaluated alpha is drawn by the renderer as Overlay::Mask (CPU and GPU share the

view.maskPins hides them. CPU/GPU equivalence and headless keyboard/pointer tests.
