Second half of lot 1. The catalogue mirror (#547) landed the server's albums locally and the cover cache (#549) made them paintable; nothing showed them. This does.

list_library_albums returns both halves as one sorted list tagged by source, and the source becomes a filter inside the list rather than a section beside it. That is the whole difference between a unified library and two tabs.

Decision 1 is untouched

An album held on both sides appears twice, tagged twice. Unifying the navigation is not deduplicating the catalogue — that is reserved for its own RFC — and the chip on the cover is what says so.

Two things only a run against a real database showed

  • The sort keys have to be normalised on both sides. The local half sorts on canonical_title / canonical_name, forms produced by normalize_name: lowercased, diacritics folded, punctuation dropped. SQLite reproduces none of that — COLLATE NOCASE is ASCII-only — so sorting the remote half on its raw display name put "Björk" and "bjork" in two different places and split one artist in half down the middle of the list. remote_album now carries sort_title and sort_artist through the same function, written by the mirror. Rows from before those columns existed fall back to their display title, and one walk fills them in.
  • A local library filter has to exclude the remote half. The picker chooses among local libraries and a server album belongs to none of them; leaving those rows visible while the user has narrowed to one library reads as the filter having failed.

What a server album does not get

No playlist, no cover picker, no context menu — none of them can accept it. It opens the remote detail view. The filter hides itself when no server is bound: a filter whose second option is permanently empty is worse than no filter, and most profiles are local-only.

Why the ordering is its own clause

album_order_clause sorts on the inner tables' own columns (al.canonical_title, MIN(t.added_at)), which do not exist outside the local half of a union. The new clause sorts on the columns the union projects, so both halves obey one comparison and one collation. A list sorted differently depending on where a row came from would be worse than two lists.

Checks

cargo fmt --check, typecheck, lint, cargo clippy --workspace --all-targets -D warnings on the default feature set and --features sync_v2, cargo test --workspace --features sync_v2 (388 + 226, zero failures) — including 2 new tests on the sort keys. The union query was exercised against a real SQLite database with all 33 profile migrations applied: every ordering, both filters, and the fallback for rows mirrored before the columns existed.

Localised across all 17 locales.

Not in this PR

The Tracks, Artists and Playlists tabs on the same pattern, then retiring the three twin views. The pattern is proven end to end; the rest is replication.

The catalogue mirror landed the server's albums locally; nothing showed
them. This is the half that does: list_library_albums returns both
halves as one sorted list tagged by source, and the source becomes a
filter inside the list rather than a section beside it. That is the
whole difference between a unified library and two tabs.

Decision 1 is untouched. An album held on both sides appears twice,
tagged twice — unifying the navigation is not deduplicating the
catalogue, and the chip on the cover is what says so.

Two things the query had to get right, and only a run against a real
database showed either:

- The sort keys have to be normalised on both sides. The local half
  sorts on canonical_title / canonical_name, forms produced by
  normalize_name — lowercased, diacritics folded, punctuation dropped.
  SQLite reproduces none of that, COLLATE NOCASE being ASCII-only, so
  sorting the remote half on its raw display name put "Björk" and
  "bjork" in two different places and split one artist in half down the
  middle of the list. remote_album now carries sort_title and
  sort_artist through the same function, written by the mirror. Rows
  from before the columns existed fall back to their display title, and
  one walk fills them in.
- A local library filter has to exclude the remote half. The picker
  chooses among local libraries and a server album belongs to none of
  them; leaving those rows visible while the user has narrowed to one
  library reads as the filter having failed.

A server album keeps none of the local gestures — no playlist, no cover
picker, no context menu — because none of them can accept it, and it
opens the remote detail view. The filter hides itself when no server is
bound: a filter whose second option is permanently empty is worse than
no filter, and most profiles are local-only.

The ordering is deliberately its own clause rather than a reuse of the
local one: that sorts on the inner tables' columns, which do not exist
outside the local half of a union. One comparison and one collation for
both halves, or a list sorted differently depending on where a row came
from — which would be worse than two lists.

Localised across all 17 locales.

- Around line 425-429: Update the RFC’s remote-artwork flow description to match
the current contract: remote album browsing returns artwork_hash, LibraryView
passes it to RemoteArtwork, and RemoteArtwork resolves/displays the artwork
rather than resolveArtwork receiving a remote path directly. Document this
component’s role and the renderer’s actual data flow, or adjust the
implementation and RFC together so they describe the same behavior.

In `@src/components/views/LibraryView.tsx`:
- Around line 820-824: Dans LibraryView, déplacez le composant SourceFilter hors
de la branche conditionnelle hasContent afin qu’il reste affiché pour l’onglet
Albums même lorsque la liste est vide. Conservez ses props current, onChange et

- Around line 2013-2017: Update the album card div around the onClick handler to
add role="button", tabIndex={0}, and keyboard activation for Enter and Space,
invoking the same local or remote album action while ignoring events originating
from child buttons.

Three kept, and the middle one is a trap I introduced.

Narrowing the source to a server with nothing mirrored yet empties the
album list, and the whole tab body — the filter included — was inside the
content gate. So the control that caused the emptiness disappeared with
it, leaving no way back to "All". The filter now sits outside the gate.
The sort dropdown stays inside: it cannot cause an empty list, and a sort
control over nothing is noise.

That emptiness also inherited the wrong advice. The generic empty state
offers "Import a folder", which is right for a library with no music and
wrong for a library whose local half is full and whose server half has
not been walked yet — importing adds nothing to the half being looked at.
A narrowed source now says so, and points at the two things that would
actually help.

The album card was a bare div with an onClick, so it could not be reached
by keyboard at all. It now carries role="button" and tabIndex, activates
on Enter and Space, and ignores key presses that started on the "+"
button nested inside it — that button is focusable in its own right and
its keys are its business. Space has its default suppressed so activating
a card does not scroll the page.

And the RFC described the cover cache accurately but stopped one layer
short: the listings carry the hash, not the path, and RemoteArtwork is
what turns one into a cover. Resolving server-side would cost a round
trip per row before a page could be answered, on a list virtualised
precisely so most rows are never looked at.
