Lots of Library albums showed no cover. Two cases, both common for new singles from playlist syncs:

• No MusicBrainz ID. A new single MusicBrainz doesn't list yet has no release group, and the cover lookup stopped there without trying anything else.
• Dead cover link. When the release group's saved cover link returned 404, Aurral counted it as a temporary failure and kept retrying the same link.

Now, when an album has no release group or its release-group cover won't download, Aurral asks Deezer for that artist and album title. Deezer is only asked when the release-group lookup hasn't already asked it, so there are no duplicate calls and no new BrainzMash calls. A cover found this way is saved like any other, including the cover.jpg beside Aurral-downloaded tracks, so the lookup runs once.

Proof: one new case in album-artwork.test.ts covers both, failing on main. The file now stubs Deezer with an empty catalogue so other tests don't reach it. pnpm run check, pnpm test (perf baseline unchanged), and pnpm run test:integration pass.
