- `ExportOptions.hdr` (`hdr` param): photos edited in HDR export as ISO
21496-1 gain map JPEGs (the SDR rendition as the base, the gain map measured
against it as written) or 32-bit float TIFF with highlights above 1.
Other formats and SDR edits export as before.
- Output sharpening and watermarks apply to both renditions.
- `develop.hdr {enabled?, maxEv?}` turns HDR editing on/off and sets the
headroom limit.
Checked on macOS: ImageIO reports both the ISO and the Apple gain map, and
CoreImage's HDR decode of a 3 EV edit reaches 2.95 EV.

Each photo's develop settings record the rendering process they are
interpreted by (`DevelopSettings::process`). There is one process, V1, the
pipeline as it is; nothing renders differently (180 CPU 8/16-bit and GPU
renders of procedural scenes, and the saved settings JSON and hash64, are
byte-identical to main).
Settings saved without the field load as V1 (a field-level serde default),
new settings get the latest (`Default`), and V1 is left out when saving, so
files and preview-cache keys stay as they were. A damaged value (anything
but a whole number up to 2^32 - 1) reads as V1 too, so it never costs the
rest of the settings (an unparsable `lc:settings` sidecar is ignored). Reset moves a photo to the
latest process, section and slider resets don't; virtual copies inherit
it; copy / paste / sync / Auto Sync / presets don't carry it; a number from
a newer LightCraft is kept and renders with the newest known process. The
process is not an edit (Edited badges, import-look checks). The base tone
map is chosen per process in one place (`finish::base_tone`, shared by CPU
and GPU). Photo > Update to Current Process (`develop.updateProcess`) moves
selected photos on an older process to the latest as one undo step. Its
menu enablement follows the selection; a call that names photos (`ids` /
`id`) is validated on those instead, through a new opt-in
`CommandSpec::explicit_targets` (execute checks enablement before the
handler sees `ids`). `develop.get` reports the process. The rule and how to add V2:
docs/process-versions.md.

crop.drag {handle, from, to, start?} runs drag_crop through the command
layer so the UI, CLI, control channel and MCP agree; a locked crop keeps the
shape of its frame. crop.aspect now rejects non-finite, non-positive and
beyond-20:1 ratios and non-numeric arrays instead of storing a degenerate
lock that produced an empty crop.

- develop.quickAdjust {control, delta}: adds a step to every target photo's own value (one undo
step); the Edit panel shows Quick Develop rows (exposure ⅓ / 1 stop, contrast, highlights,
shadows, whites, blacks, clarity, vibrance, temperature) in the grid with several selected.
- library.findSimilar {id?, similarity?}: look-alike photos by their culling signature (cached
per content), most similar first, as a view filter (Filter.only); photo menu entry.
- develop.matchExposure: selected photos' Exposure set so shutter × ISO ÷ aperture² + slider
matches the active photo; photos without exposure data are skipped.
- Impromptu slideshow row marked (View ▸ Slideshow).

lightcraft-pipeline gains lut.rs: a .cube parser (LUT_3D_SIZE, DOMAIN_MIN/MAX, TITLE), a
trilinear lookup and an in-process registry; the finishing stage applies a `lut:` profile to
the display-encoded colour, blended by the profile amount (0–200 %); LUT profiles render on the
CPU. profile.import {paths} reads files, folders and zips, copies each LUT into the library's
Profiles/ folder, lists them in prefs and registers them when the library opens; the profile
browser shows them under their folder / zip name; profile.deleteImported. File ▸ Import
Profiles & Presets…, the file picker and drag & drop take .cube files.

- develop.autoSync (Edit ▸ Auto Sync, ⌥⇧⌘A): an edit of the active photo carries only the
settings that changed to the other selected photos, in one undo step; slider drags sync on
release; spots / red eye and history restores stay per photo. Edit ▸ Sync Settings in the
menu; Edit panel banner while it's on with several photos selected.
- Colour-label sets: built-in Colors / Review sets plus user sets in prefs (label.sets,
applySet, saveSet, deleteSet); listed in Photo ▸ Set Color Label; the names dialog can start
from a set and save one. XMP sidecars and exported originals write the label's name, and
reading resolves custom names back to their colour.
- Crop: ⌘-drag draws a straighten line and keeps the crop tool active.

- develop.autoBwMix (B&W Mixer → Auto): each hue band's colourful pixels are pushed away from
the image's mean lightness (light bands brighter, dark ones darker; bands with almost no
colour untouched), clamped to ±60; switches to B&W; one undo step.
- library.filter {merged: hdr | panorama | hdrPanorama | any}: Photo Merge results recognised
by the "-HDR" / "-Pano" / "-HDR-Pano" names merges write; filter bar type picker lists HDR,
Panoramas, HDR Panoramas.

- 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).

- 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.

- library.selectBy {flag, rating, ratingOp, label, add}; Edit → Select by submenu.
- preset.rename / preset.update (current settings, same groups) / preset.move; preset row
menu: update, rename, move to group (existing or new), delete.
- version.rename / version.update; version button menu: restore, update, rename, set as
before, delete. history.clear (undoable); history row menu: create version from step, clear.
- Keyword chip menu: remove, show photos with keyword, rename / delete keyword.
- A generic one-field dialog (TextPrompt) runs a command with the typed value.

- Edit → Paste Selected Settings… (⇧⌘V): group checklist prefilled with the copied groups;
develop.paste {groups} pastes only the chosen copied groups.
- Edit → Find… (⌘F, view.focusSearch) focuses the search field.
- Photo context menu: Remove from Album (in an album), Create Version, Paste Selected
Settings…, Show in Finder, Export…, Export with Preset.

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).

Auto uses Upright's consensus level angle as the crop angle; sign verified on a tilted test image
and pinned by a test.

- pipeline::upright: own gradient-based line-segment detector (level-line region growing seeded from the
strongest gradients, weighted principal-axis fit, elongation test); vanishing points by RANSAC over
segment pairs + least-squares refinement (smallest eigenvector of Σ w·l·lᵀ)
- corrections as a virtual camera rotation K·R·K⁻¹ (vertical VP → y axis; Full also horizontal VP → x axis
with focal length from VP orthogonality when plausible); Level = rotation; Auto = Full/Vertical when
moderate, else Level; all re-centred
- Guided: guides stored in normalized lens-corrected coordinates; 2+ vertical/horizontal guides define the
vanishing points, a single guide levels
- the analysis runs on the lens-corrected image at 1024 px and the result is stored in
geometry.upright_transform (identical preview/export); settings naming a mode without a transform
(XMP, CLI) are resolved at render time
- commands geometry.upright {mode} (Update = run again) and geometry.guides {guides, add}
- UI: Upright mode buttons, Update, Draw/Clear Guides in the crop panel; on-canvas guide drawing that
follows the warp
- tests: segment detector on known lines; Vertical/Auto/Full fix converging verticals; Level fixes a tilted
horizon; Full fixes both families; guided from two guides; analysis resolution independence; lazy vs
stored transform; engine commands
