Catalog date runs (stacks never split), Sort.group (auto/day/month/year/none) in the sort
menus, library.groups query, sticky headers, header click selects the group; layout unit
tests and a headless test.

- engine: QuickJob — what to show the moment a photo opens: the loupe's last render for the
current settings (kept by Session::loupe_job under a size-independent "view" key in the
preview cache, memory + disk with a library; the disk JPEG is written off the render
thread via PreviewCache::put_deferred), else the embedded camera JPEG of a raw that still
has its import look (import::has_import_look), else a thumbnail-level render.
- Grid / filmstrip: an unedited raw without a thumbnail shows its cached thumbnail, else its
embedded preview (Slot::ThumbQuick) at once; the real rendered thumbnail follows at
background priority (same cache keys, so it still ends up matching the develop render;
edited photos render directly).
- Loupe (detail, compare, filmstrip selection): Slot::Preview holds the stand-in until
Slot::Main has the photo; the full render then replaces it in place (no blank frame).
- files::embedded_preview_srgb + PreviewLoader hook (desktop/CLI/MCP and web).
- ui.inspect → loupe {photo, source: render|cached|embedded|small|thumb|none, pending}.
Real app (24 MP raws, loaded machine): first image 15–90 ms (thumbnail, then embedded
preview), full render 0.2–0.5 s (was 1.0–2.4 s with nothing shown before it).

The catalog Store on the web is an in-memory mirror (apps/lightcraft-web/src/files.rs) loaded
from browser storage at start-up and flushed in the background in modification order (so a
snapshot always lands before the log reset that follows it). Storage is OPFS when writable from
the main thread (createWritable), else IndexedDB (?store=idb forces it); ?reset clears it.
Imported originals are stored as originals/<content hash> and referenced as
web/<hash>/<name>; the main thread keeps a bounded memory cache and loads misses (and the
active photo) asynchronously. view.json and ui.json are saved every second when changed.
Engine: Session::open_library_in(LibraryStores) opens a library from any Store (presets, view
and prefs go through it too); Session::save_view; Copy imports into a non-disk library add.
JS automation API: lightcraft.command(id, paramsJson) (+ web.stats).

- pipeline::optics::Warp: one inverse map (lens-corrected → source) inside the single geometry resample:
manual radial distortion, embedded DNG WarpRectilinear (per plane), per-channel lateral CA scale,
radial vignetting gain (manual + embedded FixVignetteRadial); all in normalized radii
- automatic lateral CA estimate: radial edge profiles matched sub-pixel per plane, robust LSQ fit of
displacement = α·r (cached per source)
- defringe: purple/green hue ranges (OkLab hue) desaturated next to high-contrast edges, width relative
to the image long edge
- "Enable Lens Corrections" applies only lens data embedded in DNGs (opcodes are no longer baked at decode;
stored on the photo record, on by default at import when present). No LCP data anywhere.
- new controls: optics.caRed/caBlue, defringe hue ranges; Optics panel: Manual sub-section, Defringe flyout
- tests: barrel grid straightened, CA removal (auto + manual), embedded corrections toggle/scale, preview vs
export resolution independence, CA estimator accuracy, orientation of embedded lens data

- 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).
