Open Library given a Lightroom Classic catalog folder, one of its .lrdata /
.lrcat-data folders, Backups/, the .lrcat or its -wal/-shm/.lock files used to
create an empty LightCraft library inside Lightroom's folder (or, for the
.lrcat file, close the current library and then fail). Now:
- engine: lightroom_folder::lightroom_catalog_at (names only, top-level scan
bounded to 10 000 entries, never fails); Session::open_library refuses those
places with EngineError::LightroomCatalog {path, catalog} before creating
anything. A LightCraft library (catalog.snap / catalog.log) always wins.
- app: app.openLibrary checks before closing the current library, keeps it,
returns {opened: false, lightroomCatalog, path} and shows a dialog with
Import Lightroom Catalog… (file.importLightroom with the catalog found) and
Cancel. The library problem window gets the error instead.
- Lightroom import status keeps the catalog path after the task ends.
- CLI --library explains how to import instead.
