 The measured, row-by-row checklist: one row per Lightroom feature, menu item and shortcut, what we
 have and what is missing. It answers *does the feature exist?* (feature breadth). Whether it is good

 | LR-LIB-LABEL | Colour labels | P1 | ✅ | `cmd:photo.label`, `cmd:label.setNames`, `cmd:label.names`, `cmd:dialog.labelNames`, keys 6–9 in `crates/ui-egui/src/shortcuts.rs` | Photo menu and grid context menu (coloured, named), Info-panel swatches, label dot plus translucent colour on square-grid/filmstrip surrounds and photo-grid footers (photo pixels unchanged); colour-label toasts have pale matching backgrounds; setting/clearing through keys (including Shift), menus or Info swatches shows the same bottom toast as ratings, with the colour/custom name; editable label names (undoable, journaled); no purple key (as in Lightroom), no custom extra labels |
 | LR-LIB-KEYWORD | Keywords | P0 | ✅ | `cmd:panel.keywords`, `cmd:photo.setMeta` (`addKeywords`/`removeKeywords`), `cmd:keyword.list`, `cmd:keyword.rename`, `cmd:keyword.delete`, `cmd:keyword.merge`, `cmd:keyword.suggest`, `crates/catalog/src/keywords.rs`, `crates/ui-egui/src/panels/left.rs` | left-panel keyword tree with counts (click filters, children included; context menu rename / merge / delete / add / remove); library-wide ops are one undo step and replay from the op log; suggestions (co-occurring / most used / completions) in the Keywords panel; keywords reorganize by drag and drop in the Keyword List (LRC-LIB-KEYWORDS) |
 | LR-LIB-PEOPLE | People / faces | P2 | 🟡 | `cmd:faces.detect`, `cmd:view.people`, `cmd:view.faceBoxes`, `cmd:photo.removeRegion`, `cmd:photo.setRegion`, `cmd:library.filter`, `crates/ui-egui/src/panels/people.rs`, `crates/catalog/src/query.rs` (`people`), `crates/engine/src/media.rs` (`face_job`), `crates/meta/src/xmp.rs` | MVP: named face regions read from XMP (MWG-RS, read-only, see `docs/xmp-interop.md`; clipped to the photo; Lightroom's `Rotation` of ±π/2 and π handled, mirrored orientations taken as written; boxes follow Rotate Left/Right and flips; a sidecar stating `mwg-rs:Regions`, even empty, replaces the photo's on re-read, one without leaves them) become cards in the People view (View ▸ People, or the People button in the toolbar): a close-up of the person's largest face, name and photo count; a click filters the grid (`person` in `library.filter`, `person:` search token, filter chip). Face boxes in the loupe can be switched off (View ▸ Face Boxes, toolbar) resized with eight drag handles and removed with the × shown on hover (catalog-only and undoable, one undo step per drag; the sidecar is never rewritten for either); no moving a box by dragging it yet. Photo ▸ Detect Faces (`cmd:faces.detect`) finds faces with the YuNet detector (pure Rust, about 200 ms a photo, matches OpenCV's own YuNet on a 45-photo test set; the 232 KB model is a one-time download offered in the same step, never part of LightCraft) and adds them as unnamed boxes; names are suggested from the faces already named (recognition models are opt-in downloads, run on the CPU in a background thread; a face is named only when you confirm it); a person's page shows their cropped faces and the unnamed faces that look like them (LRC-LIB-PEOPLE), with a user-triggered ↑ action or targeted A key to name all shown suggestions at or above one score in one undo step; with recognition on, a background scan finds faces in photos that have none and embeds every face (one to three worker threads, raws through their embedded preview); an Unnamed faces section orders faces by likeness and names a selected group at once; no separated clusters, no manual tagging, no writing regions back |

 | LR-LIB-DELETE | Delete / Recently Deleted | P0 | ✅ | `cmd:photo.delete`, `cmd:photo.restore`, `cmd:photo.deletePermanently` | Delete and Delete Permanently retain surviving selected photos; if none remain, select the next visible survivor (previous at the end) in the current source/filter/sort; permanent deletion removes catalog records, not files on disk; Restore and Delete Permanently in the Photo menu and the photo context menus for photos in Recently Deleted (before, the UI had no way to restore); importing a file that is in Recently Deleted again restores the photo with its edits, rating and albums (issues #298, #706: before, the import skipped it as "already in the library" while the grid showed it deleted) — the review dialog checks it, badges it "Will be restored", counts it as "in Recently Deleted" rather than "already in the library", and its choice Restore them / Import as new / Leave them starts on Restore; with Leave them such a file starts unchecked and Check All and the file-type toggles leave it out, but a click still checks it and it is restored (issue #1285: before, the click did nothing and the "In Recently Deleted" badge was drawn over the checkbox, which now sits above it); dropped files restore too ("Restored 1 photo from Recently Deleted"); a deleted photo matched by content whose file is gone is relinked to the imported file; Photo ▸ Empty Recently Deleted (`cmd:library.emptyRecentlyDeleted`, one undo step, shown while the trash is the source); import takes `onDeleted` restore (default) / skip / fresh for files in the trash (`cmd:library.import`; the report lists `restored`, and with skip flags the duplicate `existingDeleted`); browsing a folder in Local (`cmd:library.browse`), Auto Import and a Lightroom catalog import never restore a deleted photo; no confirmation dialog, no auto-purge after N days (needs a deleted-at date in the catalog); Delete asks first ("Move this photo to Recently Deleted?") from the key, the Photo menu and the photo context menu, on by default and switched off in Settings ▸ General (#1239: before, it was off by default and the context menu never asked); no auto-purge after N days (needs a deleted-at date in the catalog) |
