- lensfun's data/db (CC BY-SA 3.0) is fetched by the desktop app on first
run into <config dir>/lensfun, pinned to commit 43f9e001 by name, size and
SHA-256, staged until every file is verified, with an activity row (never
bundled). LIGHTCRAFT_LENSFUN_URL lists other mirrors; LIGHTCRAFT_LENSFUN_DIR
still wins. lens.downloadDatabase / lens.databaseStatus for agents.
- The database is read per folder and again after a download; when it
changes, library raws without a profile whose lens it knows are probed in
the background and get it (untouched photos switch the correction on as
import would); ticking Enable Lens Corrections looks those photos up again
(library.refreshLensProfiles).
- EmbeddedLens records its source (file / lens database); the Optics panel
says "Profile: <lens> (lens database)", "Profile: from the file" or
"No lens profile found for <lens>." (13 locales).
- Tests: pinned download and refusal of a wrong file, the lookup and its
edited / untouched rules, and presets / Copy-Paste / Sync carrying only the
switch and amounts, each photo keeping its own lens's profile.
