 | LR-BEHAV-RENDER-FIDELITY | Rendering matches Lightroom | P1 | 🟡 | `crates/pipeline/src/lib.rs`, `crates/pipeline/src/tone.rs` | every slider exists and works, but the character of the result (tone curve shape, highlight recovery, texture / clarity / dehaze, noise reduction, sharpening, default look) is tuned by eye; there is no systematic side-by-side comparison against Lightroom on the same CC0 raws. Needs a fidelity suite: Lightroom reference renders kept only in the local `plan/` (never committed), compared per slider and preset with a perceptual metric. Tuning that changes how existing settings render ships as a new process version (LRC-DEV-PROCESS, `docs/process-versions.md`) |
 | LR-BEHAV-DRAGDROP | Drag and drop | P1 | ✅ | `crates/ui-egui/src/lib.rs`, `crates/ui-egui/src/panels/grid.rs` (`drag_feedback`), `crates/ui-egui/src/panels/left.rs` (`drop_target`, `album_drag_over`, `top_level_drop_target`, `drag_auto_scroll`) | files → app (a drop-target card while they hover, then the import review); grid photos → an album row (adds the selection, with a count badge while dragging); sidebar album / folder rows → a folder (moves it; its name follows the pointer); a drag of albums or grid photos near the top or bottom edge of the sidebar scrolls it (faster nearer the edge, only while the pointer is over the sidebar) |

 | LR-BEHAV-SIDEBAR-COLLAPSE | Collapsible left-sidebar sections | P2 | ✅ | `crates/ui-egui/src/panels/left.rs` (`section`, `section_header`), `crates/ui-egui/src/sidebar.rs` (`SidebarLayout`), `crates/ui-egui/src/tests/panels.rs` | click the Albums, Local, By Date, Folders or Keywords header (or drive `ui.clickWidget` `sidebarSection:<albums\|local\|byDate\|folders\|keywords>`) to fold or unfold the section; a chevron before the title shows the state; the choice is kept across restarts (`sidebar` in the UI state; the `collapsedSidebar` list of older settings files is still read). the click itself is UI-only, like the By Date / Keywords disclosure triangles, and `cmd:view.sidebarSection` `{section, collapsed}` folds and unfolds for agents; photos dropped on a folded Albums section have no target |
 | LR-BEHAV-SIDEBAR-SECTIONS | Left-sidebar sections share one frame and one arrangement | P2 | ✅ | `crates/ui-egui/src/sidebar.rs` (`SidebarSection`, `SidebarLayout`), `crates/ui-egui/src/panels/left.rs` (`section`, `section_header`, `tree_toggle`), `crates/ui-egui/src/tests/panels.rs` | Albums, Local, By Date, Folders and Keywords are drawn by one `section` frame (the same gap above, header, fold and accessibility name) from one arrangement, `sidebar` in the UI state: a list of `{id, hidden, collapsed}` top to bottom, also settable with `ui.set`. Whatever is read, every section is in it exactly once (unknown and repeated entries are dropped, the rest follow in the usual order), so a damaged or newer settings file never loses the other settings. Rows that open (album folders, Local folders, dates, library folders, keywords) share `tree_toggle`: the same triangle, the same remembered open state, announced as Expand / Collapse. A section with nothing to list (Folders before anything is imported, Keywords before any is added) stays, open, with a one-line note in place of rows (`sidebarEmpty:<id>`) instead of disappearing. `ui.set` reads `sidebar` strictly (`SidebarLayout::parse`): an unknown or repeated section, or a flag that is not true / false, is refused and changes nothing; sections left out follow in the usual order, shown and open; the older `collapsedSidebar` list still folds and unfolds. A section may have one button at the end of its header, declared in one place (`header_button`: an icon, a tooltip, and either an action or a menu): the frame draws it at the visible edge in the header and its pinned copy, keeps its click from folding the section and leaves it room beside a folded section's count. Albums has + (`icon:albumNew`: Create Album / Smart Album / Folder…), Keywords has + (`icon:keywordNew`: Create Keyword Tag, for a keyword inside the default parent, not inside what the Keyword List has picked; once made, Keywords is shown and opened down to it). My Photos (All Photos, Recently Added, Picks, Missing Photos, Recently Deleted) is not a section: it stays on top |
 | LR-BEHAV-SIDEBAR-HIDE | Show and hide left-sidebar sections | P2 | ✅ | `cmd:view.sidebarSection`, `cmd:view.sidebarReset`, `crates/ui-egui/src/sidebar.rs`, `crates/ui-egui/src/panels/left.rs` (`sections_menu`), `crates/ui-egui/src/menus/menubar.rs`, `crates/ui-egui/src/tests/panels.rs` | View ▸ Sidebar Sections lists Albums, Local, By Date, Folders and Keywords in the sidebar's order, each checked while shown; unchecking one takes its header and rows off the sidebar, checking it puts it back where and how it was (still folded if it was). The same list opens with a right-click on any section header (with Hide This Section first; widgets `sidebarMenu:hide`, `sidebarMenu:section:<id>`, `sidebarMenu:reset`) and on the My Photos title (`sidebarTitle`), which is always there, so hidden sections can always come back. Reset Sidebar Sections (enabled once something changed) shows and opens every section in the usual order. `view.sidebarSection` `{section, show?, collapsed?}` flips shown / hidden when neither flag is given and refuses an unknown section or a flag that is not true / false. Hiding the section of what the grid shows (an album, a keyword filter) leaves the grid as it is; an album made while Albums is hidden or folded brings Albums back, open. Kept with the UI state (`sidebar`). My Photos itself can't be hidden |

+- A one-line prompt (Rename Folder, New Folder on Disk, the preset and version names, New Library for a name it can't
+  use, Auto-Tag from Tracklog) that the app refuses, for example a folder name that is taken, now stays open with what
+  you typed and shows the reason, so you can change the name. Before, it closed without a word. A New Folder on Disk
+  that works now says so: “Created folder “Selects” in “2026/Shoot””. Cancel and Esc still close the prompt.
