Port the Tauri folder-management surface to a new Settings > Local Library
sub-section (index 4); the browse-view gear routes here and pre-selects it.
UI:
- LocalLibrarySettings.slint: folder list (icon, display name, disabled/
unavailable badges, multi-select checkboxes) + toolbar (scan-all/add/edit/
remove icon buttons) + filter + Maintenance (cleanup missing) + two-step
Danger Zone clear. ADR-008: plain bordered icon buttons + square badges.
- LibFolderEditModal.slint: alias, enabled, network override + fs-type,
change-path, accessibility status, last-scanned, scan-this-folder. Mounted
at the AppShell root (overlays the window, ADR-009 by mount order).
- SettingsView gains the section-4 sub-nav + panel; app.slint re-exports the
new globals so the Rust layer can populate them.
Controller (local_library_settings.rs): load/add/remove/edit/save/change-path,
cleanup-missing (stats outside the DB lock), two-step clear, filter, select.
All DB access via qbz-library through library_db::with_db on spawn_blocking;
native dir picker + confirms via rfd. Selection preserved across reloads;
network folders get an async 6s-timeout accessibility check (exists() fallback
on timeout, mirroring Tauri).
Core (qbz-library): network_fs_label() for fs-type parity; separator-safe
delete_tracks_in_folder_prefixed() + remove_folder_with_tracks() (fixes the
prefix-collision bug without changing the legacy fn). Scan engine lands in
Slice B.
cc
Replaces the thin name+counts grid (which was built without a Tauri
review) with the real structure: a two-column master/detail, 1:1 with
the Svelte Artists tab.
Left rail: a merged/deduped, A-Z grouped master list of compact rows
(round avatar + display name + "N albums · M tracks") with a proportional
alpha jump strip and in-place search. The name-merge collapses
normalized-equal spellings into one canonical row (canonical = most
albums, tie by most tracks) and computes accurate unique album counts
from the album set's all_artists, mirroring Tauri's artistMergeResult.
Diacritics are folded best-effort (no unicode-normalization dep).
Right pane: the selected artist's albums, filtered IN PLACE from the
loaded album set by primary/all_artists/multi-credit match (no new
backend call) and rendered via the shared AlbumCollectionView; covers
load through a new LocalArtistAlbumCard artwork target. Clicking an
album opens the local album detail; the play action queues the album.
Custom DB artist images are resolved into the rail model; rendering them
(plus the capped/sequential Qobuz photo fetch) is the remaining image
follow-up — the rail shows the placeholder avatar until then.
cc
Flat mode now has the full toolbar: search, sort (artist/title/year),
group-by (off/letter/artist) and a grid/list view toggle, driven by a
derive_folders() pass that mirrors favorites::derive_albums over the
directory-grouped album set (folders-visible / folders-grouped).
Tree mode is a new two-pane filesystem browser: a flattened FolderNode
list in the left rail (lazy one-level expand via list_folder_children,
collapse drops the descendant block, recursive track counts gate the
chevron) and a detail pane on the right showing the selected folder's
direct tracks plus immediate subfolders, with Play all (recursive) and
per-track play scoped to the folder's direct list. A flat/tree segmented
toggle switches modes; the tree loads its roots lazily on first switch.
Slint has no native TreeView, so the tree is a depth-indented ListView of
visible nodes spliced on expand/collapse. No pills (ADR-008): underline
tabs, small-radius rectangles and an accent selection bar.
cc
LocalLibrary track rows (Tracks tab + local album detail) no longer carry the
favorite or offline-cache columns — they don't apply to local content. Instead
they show a subtle per-source indicator (local -> hard-drive tinted; qobuz
offline / plex -> their mark), small + flat rather than the bold album-card
badge (mirrors Tauri's track-row local indicator). TrackItem gains a `source`
field, set by every constructor (Qobuz surfaces -> "qobuz"; map_local_track ->
local/qobuz/plex); TrackRow gains `show-source`.
Also fixes Qobuz AlbumView: the track list had a Favorite column header but the
rows never rendered the heart (show-favorite defaulted false). AlbumPageView
now sets show-favorite + show-download for Qobuz albums (matching the header)
and the source indicator for local albums, with the column header switched to
match each.
cc
Fills the last empty tab: a full-loaded grid of artists (get_artists_with_filter)
with album/track counts, inline circular cards (placeholder icon for now). All
four Local Library tabs (Albums / Tracks / Folders / Artists) now browse. The
navigate match is exhaustive over LibTab. Artist images, click-to-detail, and
name-merge dedup (Tauri's artistMergeResult) are later slices.
cc
Fills the Folders tab: a full-loaded grid of albums grouped by directory
(get_albums_with_full_filter), via the shared AlbumCollectionView (grid +
source badge), covers loaded from disk, loaded once on first visit. Clicking
a folder album opens its detail + plays it — navigate_local_album and
play_local_album now resolve tracks via fetch_album_tracks_blocking, which
tries the metadata grouping (Albums tab) then the folder grouping (Folders
tab), so both album views work. New ArtworkTarget::LocalFolderCard applies
covers to the folders model.
Tree mode (two-pane lazy folder tree) + folder search/sort are later slices.
cc
Clicking a local album (grid card or a track row's album link) opens its
detail in the shared AlbumPageView. navigate_local_album loads the album's
metadata-grouped tracks (get_album_tracks_metadata) + fills folder covers,
populates AlbumState (title / album-artist or "Various Artists" / cover /
quality / "N tracks · duration" / disc-ordered TrackRows) with a new is-local
flag, and resolves the cover from disk. Play routes to local: the media-action
dispatcher gains a guard — when the album view shows a local album, album play
-> play_local_album, a track row -> play the album from that track; Qobuz
album/track play is untouched (guarded by view==Album && is-local).
cc
Three playback-correctness fixes reported after testing:
- Album/offline cover art now reaches the now-playing bar AND the queue:
fill_missing_covers fills a track's artwork from the folder cover when the
index has no artwork_path (the offline-cache writes cover.jpg into the track
folder but doesn't always backfill the index), applied when building local /
album play queues. The cover that exists on disk shows, not just on the grid.
- Queue-panel art is source-aware: load_artwork routed every cover through an
HTTP fetch, so local file:// covers silently failed. It now parses the url
into an ArtworkRef (Remote vs LocalFile) and decodes local files from disk.
- now-playing/queue current-track mismatch: the poll loop treated ANY track-id
change while playing as a gapless hand-off and advanced the queue pointer,
which falsely fired on a manual new-track play and desynced now-playing from
the queue (erratically, by timing). It now advances only when the new id is
the expected upcoming track (a real gapless next); Qobuz gapless is unchanged.
cc
The Tracks list scrollbar sat inside the 32px content padding (too far into
the content). Move it to the view's true right edge — the position the Albums
grid already uses, which is the standard for chrome-bezel views: a padded
VerticalLayout holds the ListView while the ListScrollbar floats at the
full-width edge.
cc
A Local Library album, or the Tracks list, now plays through with auto-advance
across mixed local/offline sources.
The one change to the shared playback path is additive and provably safe for
Qobuz: play_audible gains a guard at the top — when the CURRENT queue track's
source is "local" (and its id matches), it plays the file from disk via
play_local_file_audible (read -> player.play_data + CUE seek); otherwise it
falls through to the EXISTING offline/Qobuz tier-walk, byte-for-byte unchanged.
Qobuz/offline queue tracks never carry source "local", so their behavior cannot
change. Auto-advance, next/previous and play-all all route through play_audible,
so they become source-aware for free. current_track() releases the queue read
lock before play (no nested lock / deadlock).
- qbz-player: QueueManager::current() (additive).
- qbz-core: QbzCore::current_track() (additive).
- qbz-slint playback.rs: source-aware play_audible + play_local_file_audible
(extracted) + play_local_tracks_now + play_local_album
(get_album_tracks_metadata) + play_local_tracks_from (search_with_filter);
replaces the Stage-1 single-track helper.
- main.rs: album card "play" -> play the album; Tracks row "play" -> play from
that row down the searched list. (play-next / queue still stubbed.)
Built green (cargo check). Local-file gapless isn't wired (local tracks aren't
prefetched, so local/mixed transitions use the simple track-ended -> next path);
Qobuz gapless is unchanged. Runtime smoke-test pending: (1) Qobuz streaming
still plays + advances, (2) an offline album advances, (3) a local album/list
advances.
cc
First source-aware playback stage. Clicking a track in the Local Library
Tracks tab now plays it, mirroring Tauri's v2_library_play_track routing:
- offline-cached (qobuz_download) tracks reuse the shared tier-walk
(after_track_change -> play_track_resolved -> offline resolve -> play_data),
keyed by the Qobuz id;
- local user files are read from disk and handed to the player's play_data
seam (which extracts the sample rate + drives the PROTECTED device init,
untouched), with a CUE seek for virtual tracks.
Additive: play_local_library_track + local_queue_track (mirrors Tauri's
local_track_to_queue_track) are new; the shared Qobuz play_audible path is
unchanged (no regression risk to streaming). Single-track play (a 1-track
queue) — album/queue + auto-advance need a source-aware advancement handler
and land in the next stage. Built green (cargo check -p qbz-slint);
runtime smoke-test pending (a local FLAC + an offline track should play).
cc
Adds the Tracks browse tab. Each page is a search_with_filter_page query
(new paged variant of search_with_filter) appended on scroll-near-bottom, so
the list never materializes the whole table — the documented ~16K-row Tracks
freeze. Reuses the shared TrackRow in a virtualized ListView + ListScrollbar
(the Favorites Tracks pattern) and the Albums controller's generation-guard
(TRACKS_GEN) so a search/retry can't be clobbered by a stale in-flight page.
- qbz-library: search_with_filter_page(query, offset, limit, include_qobuz,
exclude_network) — same ordering as search_with_filter, LIMIT/OFFSET.
- local_library.rs: map_local_track (LocalTrack is Send -> crosses
spawn_blocking; TrackItem built on the UI thread), fetch_tracks_page,
apply/append, reload/ensure/load_more (TRACKS_GEN-guarded).
- LocalLibraryView.slint: Tracks body (ListView + TrackRow, show-artwork off
per Tauri's perf default, show-favorite/show-download off) + a search
toolbar + loading/error/empty states.
- state.slint + main.rs: tracks state/actions + lazy load on first visit +
search/load-more/retry wiring.
Group-by, multi-select/bulk, and per-row playback land with the source-aware
playback slice (track-action is a stub, like Albums). Built green
(cargo check -p qbz-slint); runtime smoke-test pending.
cc
Generalize resolve_album_cover_fallback beyond a single track + cover.jpg:
scan several of the album's tracks (CMAF keeps each track in its own folder,
only some of which may carry a cover), check both the track folder and its
parent (multi-disc layouts keep art one level up), and accept the common
local cover filenames (cover/folder/front, jpg/png). Resolves more on-disk
covers without touching the paged query. Albums whose offline bundle never
saved a cover (segments only) still need an offline-cache cover re-fetch.
cc
Two fixes from the first Albums-grid test pass.
Offline/folder covers (the reported "cover exists in the folder but isn't
shown"): some albums — offline-cached CMAF bundles and folder downloads —
have no artwork_path in the index even though a cover.jpg sits in the track
folder (older offline-cache downloads didn't backfill it). Add a frontend-
agnostic LibraryDatabase::resolve_album_cover_fallback(group_key) that finds
a representative track, derives its folder (the path itself for a CMAF bundle
dir, else the parent), and returns <folder>/cover.jpg when it exists. The
Slint Albums mapper calls it whenever the album has no artwork. Verified
against the live index: it resolves the folder covers that exist on disk
(FLAC-layout + CMAF-with-cover). Older CMAF bundles that never downloaded a
cover (segments only) still show the placeholder — those need a cover
re-fetch (offline-cache maintenance), tracked separately.
Source badge: the Local Library album card now shows the always-visible
source badge inside the artwork (bottom-right) — a hard-drive glyph for local
files, the Qobuz logo for offline copies, the Plex logo for Plex. Added
AlbumCard.show-source-badge (default off; threaded through AlbumCollectionView
/AlbumGrid) + AlbumCard.source; album_map now carries the real source and
map_local_album maps user->local / qobuz_download / plex. Small rounded
square, not a pill (ADR-008). Logos copied into the Slint icon assets.
Built green (cargo check -p qbz-slint); runtime smoke-test pending.
cc
First Local Library data slice. The Albums tab browses the metadata-grouped
local albums via the performant server-paginated path (the same query Tauri's
chunked store uses), reusing the shared AlbumCollectionView grid — no new
rendering. Scales past the documented ~16K-row Tracks freeze by never
materializing the full set.
- local_library.rs: map_local_album (LocalAlbum -> the plain album_map
AlbumCard, Send-safe; the non-Send slint::Image conversion via to_item
happens on the UI thread), local_quality (Hz -> kHz), sort_params; a
blocking fetch_albums_page over LibraryDatabase::get_albums_metadata_page
(spawn_blocking); apply/append + reload/ensure/load_more driven by an
ALBUMS_GEN generation guard so a search/sort/retry can't be clobbered by a
stale in-flight page.
- LocalLibraryView.slint: Albums body reusing AlbumCollectionView (grid,
show-favorite: false), a search + sort toolbar (both server-side), auto
load-more on scroll-near-bottom (DiscoverBrowse pattern), and loading /
error+retry / empty states.
- Local covers: ArtworkTarget::LocalAlbumCard + spawn_local_loads resolve the
on-disk cover path through the source-aware ArtworkRef::LocalFile pipeline;
the target carries the generation so a cover decoded after a reload is
dropped instead of landing on a replaced row.
- state.slint: LocalLibraryState album fields + LocalLibraryActions callbacks.
- main.rs: navigate_local_library lazily loads page 1 on first visit; the
on_albums_* callbacks wire search/sort/load-more/retry (open-album /
open-artist / album-action are TODO no-ops until the detail + playback slices).
List/group/A-Z/quality filters, album detail, and playback are later slices.
include_qobuz_downloads mirrors the show_in_library setting default (true).
Built green (cargo check -p qbz-slint); runtime smoke-test pending.
cc
The shared AlbumCard always rendered the favorite heart (overlay button +
"Add to favorites" menu item). Local Library albums are not Qobuz-favoritable
(Tauri's AlbumCardLibraryLite hides favorite/genre), so the upcoming local
grid needs to suppress it.
Add an additive `show-favorite: bool` (default true) on AlbumCard, threaded
through AlbumCollectionView -> AlbumGrid. The fav overlay button uses
`visible:` (not an `if`) so it stays referenceable by `overlay-on` (keeping
the Qobuz hover-no-flicker behavior intact); the menu item is gated with an
`if`. All existing callers (Discover / Favorites / Label) default to true,
so behavior is unchanged.
cc
The nav-scaffolding view (c50ae171) invented its own chrome: a title+stats
header with no NavButtons (so no back/forward history nav), plus a tab bar
of border-radius:18px pill chips — an ADR-008 violation. Rebuild it 1:1 on
the app's mandatory fixed-chrome header (the same FavoritesView/Discover
use):
- Row 1: NavButtons (back/forward) + "Local Library" title (left), the tab
menu floated right. Tabs are underline tabs (LibTab/LibTabMenu mirroring
FavTab/FavTabMenu) — no pills.
- The settings gear becomes a standalone icon-only circle matching
NavButtons (the one circular shape ADR-008 permits), routing to
Settings > Local Library.
- Row 2 (per-tab actions + toolbar) is established with vertical-stretch:0
so it doesn't inflate while empty; filled per slice (Albums next).
- 1px divider, then a single scrolling content area with a placeholder.
Wiring (select-tab / open-settings, nav, mount) is unchanged — only the
.slint chrome was rebuilt.
cc
Add the frontend-agnostic contract for the source-aware playback context:
- qbz-models: new `source` module with `PlaybackSource` (Qobuz / OfflineCache
/ Local / Plex; parses the existing stringly-typed `source` field, defaults
to Qobuz) and `ArtworkRef` (Remote / LocalFile / PlexThumb / Embedded /
None). `QueueTrack::source_kind()` + `QueueTrack::artwork_ref()` derive both
without changing the wire format. `PlaybackSource::is_qobuz_streamable()`
seeds the Qobuz Connect queue gate (only Qobuz-sourced tracks are castable).
- qbz-slint artwork pipeline: `fetch_and_decode_ref(&ArtworkRef, ...)` resolves
cover bytes per origin — HTTP/Plex through the disk cache, local files read
directly, embedded bytes in place. This fixes the root cause of local/Plex
artwork never reaching the UI (the loader was HTTP-only). The URL-only
`fetch_and_decode` becomes a thin wrapper, so all existing card/row jobs are
unchanged. The now-playing loader now takes an `ArtworkRef` derived from the
queue track, so local-library/Plex covers reach the now-playing bar.
Groundwork for the Local Library Slint port (source-aware playback context
designed in from the start). qbz-models tests pass; qbz-slint cargo check green.
cc
Move the Plex LAN client, hand-rolled XML metadata parsing, and the
SQLite plex_cache.db logic out of src-tauri/src/plex/mod.rs into a new
qbz-plex core crate so it can be shared by every frontend (Tauri, Slint,
TUI) per ADR-006. Plex previously lived entirely in src-tauri (~1715
lines), which blocked the Slint Local Library port from shipping Plex.
The extraction is mechanical: the module was already almost entirely
plain Rust (reqwest + rusqlite + serde + hand-rolled XML). The only
Tauri coupling was a dead plex_play_track command bound to AppState
(unreferenced; the live path is commands_v2::v2_plex_play_track, which
calls plex_resolve_track_media + AppState.player itself). That dead fn
and the vestigial #[tauri::command] attributes are dropped.
src-tauri/src/plex/mod.rs becomes a `pub use qbz_plex::*;` re-export so
every existing crate::plex::* call site compiles unchanged. Full Tauri
workspace cargo check stays green; qbz-plex tests pass.
cc
The Cloudflare proxy funnelled every user's MusicBrainz traffic onto a few
egress IPs, and MusicBrainz rate-limits 1 req/s per IP, so the budget was
shared across the whole userbase and produced 503s that worsen with growth.
MB read access needs no key and authentication does not raise the limit, so
the proxy added only the funnel; going per-IP makes the budget per-user.
- qbz-integrations MusicBrainzConfig default is now use_proxy=false (direct).
- client: handle HTTP 503 + Retry-After (not just 429, which the proxy used
to translate); add parse_retry_after; route search_recording_by_isrc and
search_artist through handle_response_status.
- src-tauri session_lifecycle: MusicBrainz V2 init/teardown pass use_proxy=false.
Slint inherits this via CoreBridge's default-constructed client.
cc
The panel improvised its own title + free-form paragraph + ghost buttons,
breaking the established Settings structure. Rebuilt it like Audio/Playback/
Appearance: a GroupHeader ("OFFLINE CACHE") + SettingRow rows (label +
description + a SecondaryButton control on the right) — Manage offline cache /
Cache folder / Clear offline cache. No panel-level title (the left sub-nav
names the section). Keeps the layout consistent for the offline settings we'll
add here later.
cc
Per user feedback:
- Multi-select: a checkbox on every track row + "Select all"/"Clear" toggle +
a bulk bar ("N selected" / Re-download / Remove). Selection is an in-place
model edit (offline_manager::toggle_select / set_all_selected) with a live
selected-count; bulk reads the checked ids and runs redownload_track /
remove_cached per track.
- Moved the status glyph to the END of the row (albums and tracks) — it read
as "missing art" at the leading edge under the album-grouping model.
- Track rows now show their position number in the leading slot (filling what
looked empty). (Position within the album; the catalog track number isn't in
the cache index.db — a follow-up if the real number is wanted.)
qbz-slint compiles clean.
cc
Closes the v1 gaps in the offline manager toward Tauri parity:
- Album COVERS: rows load the on-disk cover.jpg (per album). Built Send-safely
— the worker passes the cover PATH (string), the image is decoded on the UI
thread (slint::Image is not Send).
- Two-pane layout with an A-Z ARTIST RAIL (left, "All artists" + per-artist
"N albums · M tracks", selectable) + the discography list (right).
- SORT dropdown (A-Z / Recent / Largest / Smallest; Recent uses the DB's
last_accessed_at DESC order) and a "Failed only" toggle. Filter state lives
Rust-side (offline_manager) so rebuild can read it off-thread; mirrored back
onto OfflineManagerState for the UI.
- Limit now PERSISTS to disk (<audio>/offline_limit), restored on activate via
apply_persisted_limit; the manager's edit-limit writes it.
- Manager mutations (remove/redownload/clear) now rebuild on completion
(offline_manager::rebuild made pub, called at the end of each cache op) —
the 500ms timed reload hack is gone.
Deferred (user-accepted): the "track no longer available on Qobuz" case —
offline copy still plays, but warn it can't be re-downloaded / won't work on
Qobuz Connect.
qbz-slint compiles clean.
cc
- offline_cache::cache_album fetches an album's tracks and batches them; wired
to a new ("album","cache") media-action arm + a cloud-download CircleAction in
the AlbumPageView header action row.
- Favorites track rows now enable show-download, so the direct per-row offline
button shows there too (not just album rows / cached tracks).
Rounds out Slice 2: trigger surfaces (per-row button on album+favorites, context
menu everywhere, bulk multi-select, album header), live status (spinner/check/
alert) + seeding, and the unlock padlock. qbz-slint compiles clean.
cc
A cached track now shows its "ready" check when a view is built, persisting
across navigation within the session (was: only live downloads showed state).
- offline_cache.rs: a session-wide CACHED_IDS set (mirrors fav_cache), seeded
from index.db ready rows via load_cached_ids() on login/restore, kept in
sync as downloads complete (mark_cached true) and copies are removed (false).
is_cached(id) reads it.
- The 7 TrackItem builders seed cache-status from is_cached (favorites/search
clone/precompute the id to avoid moving it before the borrow).
- auth.rs calls load_cached_ids after the offline cache activates.
qbz-slint compiles clean.
cc
The queued/downloading state showed a static loader-circle. Split it into its
own `if` arm that continuously rotates via animation-tick (same technique as
LoadingSpinner), isolated so the per-frame tick only drives a row while it is
actually downloading. The idle/ready/failed glyph stays static. Communicates
that the backend is working.
cc
Adds the 6th MultiSelectBar action -> offline_cache::cache_tracks(selected),
mirroring Tauri's bulk caching. Clears the selection after queuing. (Also
retires the cache_tracks dead-code warning.)
cc
The CMAF download opened the SecretBox (OS keyring -> secret-service -> a
synchronous zbus D-Bus round-trip) directly on a tokio async worker, which
panicked ("Cannot start a runtime from within a runtime") and poisoned the
vault mutex — every later attempt then failed and fell back to the legacy
plain-FLAC path. Playback never hit this because load_cmaf_bundle already runs
inside spawn_blocking.
- downloader: wrap the vault open + key wrap in tokio::task::spawn_blocking
(off the async pool), mirroring the playback decrypt path.
- secret_vault: get_or_init recovers a poisoned mutex (into_inner) instead of
wedging the vault for the rest of the session.
Verified at runtime: CMAF bundle now persists (tracks-cmaf/<id>/) and plays
back decrypted; no panic, no legacy fallback.
cc
TrackRow now renders the offline state the controller maintains:
- The offline button is stateful: cloud-download (none, click -> cache) ->
loader-circle accent (queued/downloading) -> circle-check accent (ready,
click -> uncache) -> triangle-alert red (failed, click -> retry). Shown on
surfaces that enable it AND on any row with active cache state.
- The unlock PADLOCK (user-requested, back from Tauri): a pulsing lock glyph
overlays the play cell while the track's CMAF bundle decrypts, driven by the
`unlocking` flag the row_sink toggles on UnlockStart/UnlockEnd. New lucide
lock.svg / lock-open.svg assets.
The context menu's "Make available offline" already routes to caching. Testable
loop: cache a track (album button or context menu) -> watch it download -> play
it offline -> padlock pulses during decrypt. qbz-slint compiles clean.
cc
The Rust half of the trigger/status UI:
- offline_cache.rs: cache_track / cache_tracks / remove_cached + row_sink — a
CacheEventSink that reflects download status (queued/downloading%/ready/failed)
and the unlock padlock onto every visible row, plus terminal toasts. cache_*
pre-flight the limit, insert the queued row, and spawn the shared
spawn_track_cache_download with the core client.
- TrackItem gains cache-status / cache-progress / unlocking; set_row_cache_status
+ set_row_unlocking mirror set_row_favorite (walk the 6 track models + search
hero). All 7 exhaustive initializers updated.
- media-action arms ("track","cache"|"download"|"uncache") dispatch to the
controller; the play path now passes row_sink so UnlockStart/End fire the
padlock state during CMAF decrypt.
Compiles clean. Next: the TrackRow.slint affordance (make-offline button + ring
/ check / warn) and the padlock glyph that render these fields.
cc
- offline.rs: constructs + owns a per-user OfflineCacheState (same index.db +
library.db paths as Tauri, so the offline store is shared across frontends);
activated on login/restore, torn down on logout (hooks in auth.rs).
- playback.rs: play_audible + the gapless trigger now route through QbzCore's
play_track_resolved / fetch_for_gapless_resolved, so an offline-cached track
resolves from disk (decrypt -> play_data) before hitting the network. The
unlock-animation sink is None for now (padlock lands with the Slice 2 UI).
qbz-slint compiles clean. Offline PLAYBACK now works in Slint; the "Make
offline" trigger UI + per-row status + the padlock are next (Slice 2).
cc
The shared tier-walk compose methods both frontends call (player untouched):
- play_track_resolved: offline-first (resolve_offline_bytes -> play_data, warms
L1) else Player::play_track (which already does L1/L2 -> CMAF -> legacy).
- fetch_for_gapless_resolved: L1/L2 (player cache) -> offline -> network; the
offline tier is only tried when the track is NOT in the player cache (the
CMAF decrypt is slow, so a cached copy wins — matches the Tauri gapless order).
Both take the frontend's OfflineCacheState by ref (no duplicate DB handle) and
an optional CacheEventSink for the unlock animation. Compiles green.
cc
Adds qbz_core::offline_resolve::resolve_offline_bytes — the OFFLINE tier of
the playback tier-walk, frontend-agnostic and player-untouched (the user's
locked Slice-1 decision): resolve a track's offline-cached bytes by Qobuz id
(v2 CMAF decrypt via the secret vault, optionally emitting UnlockStart/End
through a sink; v1 plain-FLAC read; None on miss).
qbz-core now depends on qbz-offline-cache (aligns with the long-intended
`offline` feature seam). Both frontends will slot this in before the network
tier: Tauri keeps its hardware/quality gate around the returned bytes; Slint
calls it before Player::play_track. Player's L1/L2 + network path is unchanged.
Next: QbzCore compose methods (play_track_resolved / gapless), wire Slint's
session to construct + own an OfflineCacheState, route the Slint play path
through the resolver, and point Tauri's offline branch at it.
cc
Completes Slice 0. src-tauri now depends on the qbz-offline-cache crate; the
old src-tauri/src/offline_cache/ implementation files are deleted. What remains
in that module is a thin shim: a re-export of the crate plus the Tauri glue.
- offline_cache/mod.rs: pub use qbz_offline_cache::* + tauri_cache_sink (maps
CacheEvent -> the exact legacy offline:caching_*/offline:unlock_* app.emit
shapes, so the Svelte frontend is unchanged) + core_client (resolves the core
qbz_qobuz::QobuzClient from the CoreBridge for the download pipeline).
- Cache/redownload/migration commands: drop the legacy crate::api::QobuzClient
(state.client) + the CoreBridge double-plumb; pass one core client + an
app.emit-backed CacheEventSink. Unused `state: State<AppState>` params dropped.
- Playback + library cached-resolution call sites: pass &tauri_cache_sink(..)
to load_cmaf_bundle_with_ui_events instead of &app_handle.
- session_lifecycle: apply_persisted_limit now reads the persisted value here;
purge takes &library.db directly.
- migration: qobuz_client is the Option-wrapped core client (consistent with the
downloader); None mid-loop is recorded as a per-track failure.
Full src-tauri cargo check passes; behaviour-preserving for the Svelte frontend.
Backend extraction (ADR-006) done — next is Slice 1 (shared tier-walk in core).
cc
Completes the crate extraction (Slice 0 backend half):
- state: OfflineCacheState holder (db/fetcher/cache_dir/limit/semaphore/
library_db + dir-layout helpers + new/init_at/teardown). apply_persisted_limit
now takes Option<u64> (the caller reads it from offline_settings) instead of
borrowing src-tauri's OfflineState, so the struct is frontend-agnostic and
Slint can own one too.
- purge: purge_all_cached_files takes &Mutex<Option<LibraryDatabase>> directly
instead of src-tauri's LibraryState wrapper.
The crate is now self-contained (13 modules, no Tauri). Next: re-wire the
Tauri commands onto it with an app.emit-backed CacheEventSink and delete the
old src-tauri/src/offline_cache/ module.
cc
Moves the download pipeline into the crate and removes its Tauri coupling:
- event: new CacheEvent enum (Started/Progress/Completed/Processed/Failed/
UnlockStart/UnlockEnd) + CacheFormat + the CacheEventSink callback type.
- downloader: StreamFetcher + try_cmaf_offline_download + spawn_track_cache_download
now report through a &CacheEventSink instead of tauri AppHandle::emit. The
CoreBridge param is gone — both the CMAF raw download, metadata fetch, and the
legacy stream-url fallback unify on a single core qbz_qobuz::QobuzClient handle.
TLS uses the workspace rustls (same backend qbz-qobuz uses for all CDN traffic).
- playback: adds load_cmaf_bundle_with_ui_events that emits UnlockStart/UnlockEnd
through the sink (the pure load_cmaf_bundle is unchanged).
Crate compiles headless; 5 unit tests pass. Remaining for Slice 0:
OfflineCacheState + purge, then re-wire the Tauri commands with an
app.emit-backed sink and delete the old src-tauri module.
cc
Continues Slice 0. Moves the near-pure modules, re-pointing the src-tauri
client/library types to the core crates (the make-or-break for a mechanical
extraction — verified the field shapes match):
- metadata: fetch_complete_metadata now takes &qbz_qobuz::QobuzClient (was
crate::api::QobuzClient); body compiles unchanged against qbz_models.
- migration: crate::api::QobuzClient -> qbz_qobuz::QobuzClient,
crate::library::database::LibraryDatabase -> qbz_library::LibraryDatabase,
super::metadata -> crate::metadata.
- playback: the PURE load_cmaf_bundle fn (the UI-events wrapper stays out —
it becomes a CacheEventSink call in the next commit).
Deps added: qbz-models, qbz-library, tokio, reqwest, lofty. Crate compiles.
purge + OfflineCacheState + downloader (CacheEvent) remain.
cc
Slice 0 of the offline-cache port (extraction per ADR-006). Creates the new
qbz-offline-cache workspace crate and moves the tauri-free leaf modules out of
src-tauri/src/offline_cache/ verbatim:
- types: the shared serde DTOs (was inline in offline_cache/mod.rs)
- db: the SQLite cached_tracks index (super:: -> crate::types)
- secret_vault, cmaf_store, path_validator: moved verbatim
- maintenance: super:: refs re-pointed to crate::
src-tauri is untouched and keeps its own copy, so the production build stays
green; the re-point + delete happens at the end of Slice 0. Crate compiles
in isolation and all 5 unit tests pass.
Remaining for Slice 0: playback pure-fn split, metadata/migration/purge
(re-point crate::api/crate::library -> qbz_qobuz/qbz_library), the downloader
+ CacheEvent/CacheEventSink abstraction, the OfflineCacheState struct, then
re-wire the Tauri commands and delete the old module.
cc
The sidepanel left artist list is now always A-Z grouped (derive_artists
groups when group-enabled OR view-mode==sidepanel; the view toggle re-derives)
with letter headers, and an AlphaStrip on its right edge jumps the list
Flickable proportionally (same approach as the album grouping — not exact,
by design). Replaces the flat ListView.
cc
Add the grid<->sidepanel view toggle to the Artists toolbar (group select is
now grid-only, matching Tauri) and the sidepanel two-column layout: a
self-scrolling left list of SidepanelArtistRows (round thumb + name, selected
highlight) that calls select-artist, and a right column with the 5-state
machine (select-hint / loading / error / no-albums / sections). Each release
section renders its title + a flat AlbumCollectionView grid; a footer links to
the full artist page. The other-flick branch now excludes the sidepanel so the
two columns scroll independently.
cc
Wire the sidepanel backend ahead of its UI: select-artist loads the chosen
artist via artist::load_artist (reusing the /artist/page release_type
classifier per the user's decision) and apply_selected_artist maps its
release sections into selected-artist-sections (DiscoverSections) + total;
a FavoriteArtistAlbum artwork target fills the section covers. The
artists-set-view handler flips grid<->sidepanel (persisted as artists_view)
and clears the selection on the way back to grid. card_to_item is now
pub(crate) for reuse.
cc
Add the optional A-Z group toggle to the Artists grid (Group: Off/A-Z
QbzSelect, default Off, persisted via favorites_prefs artists_group).
derive_artists now buckets the filtered set into FavArtistSection letter
groups (# first, then A-Z) and builds the alpha-jump model; the grouped grid
renders per-letter headers + sub-grids and an AlphaStrip on the right that
jumps the Flickable proportionally (mirrors the Albums alpha grouping).
Also renames the favorites view header title "Favorites" -> "Library" to
match Qobuz.
cc
The per-view action+toolbar row is a HorizontalLayout whose sized children
are conditional per tab. When they are absent its auto vertical-stretch
becomes 1, so it split the leftover height with the scrolling content. The
Flickable-based tabs (artists/playlists/labels) have a small content
preferred height, leaving slack the row grabbed -> a giant empty sub-header.
Tracks/Albums looked fine only because their content fills. Pin the row to
vertical-stretch: 0 so the content always absorbs the slack.
cc
Add a Shuffle CircleAction to the Artists row-2 action cluster that opens a
random artist from the visible set (random ARTIST, not a random album —
matches Tauri). Adds favorites::random_visible_artist + the artists-shuffle
handler routing through invoke_open_artist.
cc
Point the artists grid at artists-visible (the search-filtered model) and
add the "No artists match your search" empty state. Add the Artists row-2
toolbar branch with the shared ExpandableSearch wired to artists-search +
search-artists -> derive_artists.
