The heart on a Qobuz playlist detail was wired to Qobuz /favorite/create,
which does not accept playlist_ids, so it persisted nowhere and never
reflected in the library. Rewire it to the INTERNAL library favorite
(db.set_playlist_favorite, mirroring the Favorites card + Tauri's
v2_playlist_set_favorite) and seed it on open.
Add the two missing actions on a non-owned Qobuz playlist:
- Copy to library: clone it (create + add all tracks, carrying the source
artwork + attribution) as an internal owned copy.
- Follow on Qobuz: subscribe/unsubscribe via new qbz-core passthroughs to
the existing client subscribe_playlist/unsubscribe_playlist.
Surface hearted-but-not-owned playlists in Library>Playlists by merging
the internal favorite ids into the manager list (they don't come back
from get_user_playlists). Copies/follows already appear there (owned /
subscribed). New PlaylistState.is-following / is-copied.
cc
When the queue runs out with InfiniteRadio autoplay on, build a smart
artist radio seeded by the just-finished track and start it, so playback
continues with related music and chains radio -> radio. The toggle, the
AutoplayMode preference and the radio primitives already existed; only
the trigger and the immersive button were missing.
Wire the trigger at the auto-advance queue-end (naturally peer-gated) and
enable the immersive infinity button (binds QueueState.infinite-play +
toggle-infinite-play). Add QueueController::is_infinite_play().
Tauri appends the radio and retries next(); that would replay the old
queue here because QueueManager::next() nulls current_index at the edge,
so this starts the radio fresh via play_tracks to reach the same intended
behavior. Manual-next refill is deferred (needs an explicit peer gate).
cc
The queue footer button fired a correctly-wired callback whose handler
was a stub that only logged "modal pending". Replace it with the faithful
Tauri behavior: resolve the queue's tracks (current + upcoming,
de-duplicated) and open the add-to-playlist picker seeded with them, so
the inline "Create new playlist" row turns the queue into a named
playlist and picking an existing one appends to it.
Add a reusable playlist_picker::open_for_ids(window, runtime, handle,
ids, local) that dedups the open_multi + load + apply idiom; it is also
the entry point the reco-row buttons (P7) reuse.
cc
Qobuz /radio/album and /radio/track return a tracks page that omits
`total`; the strict SearchResultsPage<Track> derive rejected it with
"missing field `total`", breaking AlbumView and Discover For You radio.
Port Tauri's lenient_page_flexible into qbz-models and apply it to
RadioResponse.tracks (now non-optional, matching Tauri); derive Default
on Track so the absent-tracks branch resolves to an empty page. Two new
qbz-models tests cover the missing-total and absent-tracks cases.
Wire ArtistView's previously-dead radio dropdown: both items now carry
ArtistState.id and have handler arms -- "QBZ Radio" -> smart pool
builder, "Qobuz Radio" -> the plain /radio/artist endpoint
(play_artist_radio, no longer dead_code). Add a "QBZ track radio"
track-menu item backed by a new play_smart_track_radio that fetches the
track to seed its performer.
cc
Surface the new Recommendations tab everywhere Discover sub-sections are listed,
and make it opt-out.
- Flyouts: the sidebar section-nav flyout and both header nav flyouts (full text
+ compact icon) now list "Recommendations" alongside Home / Editor's Picks /
For You. The Rust route handler already maps "discover-recommendations"
(strip_prefix + select_tab + ensure_loaded), so no routing change was needed.
- Opt-out: a show_recommendations flag (default on) persisted in the per-user
discover-prefs store (qbz_app), seeded into SettingsState on session start.
Settings > Integrations gains a "Show Recommendations in Discover" toggle whose
description nudges connecting Last.fm + ListenBrainz (MusicBrainz is used
automatically to match releases). Off => the tab pill and every flyout entry
disappear.
- Gating uses two mounted instances per flyout (one with the entry, one without)
because Slint can't type-infer [NavMenuEntry] from a ternary of array literals;
the HomeView pill uses a plain if.
cargo check -p qbz green.
cc
Owner-directed polish after testing the Recommendations tab.
- Full albums only: drop singles/EPs/boxsets/compilations from every album row
(Recommended Albums, Fresh Releases, Deep cuts). Qobuz's `release_type` is the
source of truth ("album" | "single" | "boxset" | "compilation"); when absent,
fall back to tracks_count >= 5. Kills the karaoke single that showed up under
Fresh Releases.
- Slop second layer: reject karaoke / tribute / "made famous by" / "in the style
of" / instrumental-version releases by artist-or-title keyword, applied both
pre-resolution (candidates) and post-resolution (the Qobuz album), so AI-slop
that still wears a full-album shape gets filtered.
- Taller rows in this view only: AlbumCard/ArtistCard/Carousel/ArtistCarousel
grow an overridable `card-height` (defaults unchanged, so Home/Search are
untouched); ExternalRecoView passes 266 to album rows and 256 to artist rows,
whose cards carry the "Similar to…" subtitle (~250px) and were clipping the
Follow chip at the old fixed 220.
cargo check -p qbz green.
cc
Owner-directed polish on the Recommendations tab to make it richer + faster +
non-repetitive.
- Common vs Recent split: the single "Recommended Artists" row over-represented a
recent soundtrack binge (a live preview showed "The Newton Brothers" flooding
the row with 8 film composers while the core metal was buried). Split into two
rows seeded from DIFFERENT periods: "More like the artists you love" (overall
top) and "Based on what you've been into lately" (1-month top) — so recent
one-offs never pollute the core taste. = 7 rows now.
- Round-robin per seed inside each artist row (re-added from the v1 engine; the
rework had dropped it) + per-seed cap, so no single seed floods the carousel.
- Results cache (48h TTL): caches the FULL built rows (serialized
ExternalCarousels) per-user, keyed by connected sources. Tab open within 48h =
INSTANT paint from cache, zero fetch; stale/missing = build + store. Rebuilds
every 48h (fresh rotation) so it's never "eternally the same" and opens stop
being slow. Distinct from the rec->Qobuz resolution cache (30d/7d).
- Toast on a real fetch (cache miss/stale): "Generating recommendations…" so the
wait is communicated; the skeleton stays; no toast on a cache hit.
cargo check -p qbz green (6m44s).

Reworks the 4th Discover tab per owner feedback (the track-heavy v1 surfaced
already-heard artists). Verified against three sources that Last.fm has NO
recommendations API (getRecommendedArtists removed; web is PJAX HTML behind the
website cookie, which the API session key cannot reach) — so recommendations are
replicated from the documented similarity recipe, and ListenBrainz provides the
genuinely clean personalized feeds.
New lineup (each row paints progressively as its builder resolves):
- Recommended Artists (Last.fm artist.getSimilar seeded by last-month top, minus
the heard set; "Similar to X, Y" subtitle on the artist card).
- Recommended Albums (Last.fm artist.getTopAlbums minus your scrobbled albums).
- Fresh Releases (ListenBrainz, from artists you follow).
- Weekly Exploration + Weekly Jams (ListenBrainz curated playlists, by source_patch).
- Deep-cut albums from artists you know (Qobuz catalog, not heard in-app).
- Cold-start fallback: Qobuz editorial top albums + artists.
The "not heard" filter is now ARTIST-level (the v1 bug derived artists from
unheard TRACKS) and compares against the LOCAL reco history + a light Last.fm/LB
top-set, not a full history sweep. Album validation (UPC -> fuzzy text) added.
qbz-integrations gains Last.fm get_artist_top_albums/get_user_top_albums and
ListenBrainz get_created_for_playlists/get_playlist_tracks/get_fresh_releases.
NOTE: the Cloudflare proxy was switched to allow ALL Last.fm read methods
(anything with ".get"), so future reads need NO proxy redeploy — but the live
proxy must be redeployed ONCE with this change or all Last.fm reads keep 400ing.

Adds "Recommendations" as a 4th Discover tab (alongside Home / Editor's Picks /
For You), rendering the qbz-external-reco engine output. NOT part of For You.
- ui: new ExternalRecoState global + ExternalRecoView (4 personalized carousels
C1-C4 with length>0 self-hide gates + the editorial cold-start rows), 4th tab
pill button in HomeView, mount on active-tab == "recommendations", skeleton
gate. Export the global from app.slint.
- bin: external_reco controller — RecoCatalog over QbzCore, per-user resolution
cache lifecycle, LocalHistory from reco_store (known artists + recent plays),
scrobbler-username gate (is_authed), build + apply into ExternalRecoState
(models built on the UI thread; slint::Image is !Send) + artwork jobs.
- bin: 6 ArtworkTarget variants + resolution arms; reco::recent_track_ids
wrapper; home::select_tab + discover_prefs::push_descriptors treat the new tab
like For You (own view, Home/Editor pushed empty); lazy-load hooks at the tab
click + both Discover nav-restore sites.
cargo check -p qbz green. Last.fm reads still need the proxy allowedMethods
deploy (separate qbz-api-proxy repo) before they return data.
cc
New frontend-agnostic crate qbz-external-reco: blends Last.fm + ListenBrainz
recommendation signals into the Discover "External Recommendations" carousels,
validating every candidate against the Qobuz catalog (ISRC direct -> MusicBrainz
inc=isrcs bridge -> fuzzy text scorer, gated) before display. Four carousels
(C1 similar artists / C2 similar tracks you haven't heard, C3 listened-but-not-
recently, C4 deep cuts from known artists) capped at 20 with daily rotation over
a larger cache-backed pool, plus a Qobuz-editorial cold-start fallback (top
albums + artists) when no external source is connected. Round-robin blend across
sources. Resolution cache (per-user SQLite, 30d hits / 7d misses, WAL).
Supporting public read methods added to qbz-integrations:
- Last.fm: get_top_artists / get_top_tracks / get_loved_tracks /
get_recent_tracks / get_similar_tracks (public reads via the Cloudflare proxy).
- ListenBrainz: get_cf_recommendations / get_recent_listens /
get_metadata_recordings (204/404 -> empty, never error).
- MusicBrainz: get_recording_isrcs (the MBID -> ISRC bridge).
Engine is headless and unit-tested (matching + cache); no qbz-ui dependency.
cc
The Slint UI for the artist_vectors suggestions, 1:1 with the Svelte
PlaylistSuggestions component (backend T1-T7 already landed):
- T8: PlaylistSuggestionsState/Actions globals (distinct from the immersive
SuggestionsState) + a controller (crates/qbz/src/playlist_suggestions.rs)
that holds the pool/pagination/dedup and calls core.generate_playlist_suggestions
on a spawned task; wired into main.rs; per-row cover artwork target; suggestions
reset on playlist navigation.
- T9: the Suggested Songs section in PlaylistView.slint (docked after the
virtualized track list), manual activation via a header wand-sparkles button,
per-row Add/Play/info/dismiss + loading/empty states; a Close (x) button hides
the panel (activated is in-out).
- T10: per-playlist dismissed-track store (playlist_suggestions_dismiss.rs),
filtered out of the pool.
- i18n keys added to es/de/fr/pt.
Owner-built and verified working.
cc
Open the per-user ArtistVectorStore (<user>/cache/artist_vectors.db) and install
it on the core (core.set_artist_vectors) at the three session-activation sites
(login, restore, offline entry), next to the sub-plan-1 reco init; drop it on
logout (core.clear_artist_vectors). The store is core-owned (no bin-side static),
so the suggestions engine reads/writes it through QbzCore. Adds qbz-reco as a bin
dependency.
cc
Add QbzCore::generate_playlist_suggestions + a per-user artist_vectors store
field (Arc<tokio::Mutex<Option<ArtistVectorStore>>>) with async
set_artist_vectors / clear_artist_vectors. It resolves each playlist artist NAME
to a confident MusicBrainz id (reusing musicbrainz_resolve_artist; the names come
from the playlist's own Qobuz tracks so they're already canonical, making the
Tauri command's extra Qobuz-name re-fetch unnecessary), then runs the
SuggestionsEngine over the core-owned clients + vector store.
Also aligns the qbz-reco builder/engine handle types to qbz-core's reality (the
plan's by-ref pattern doesn't fit): mb_client = Arc<MusicBrainzClient> (no lock,
Send+Sync); mb_cache = Arc<std::sync::Mutex<...>> (locked only in await-free
windows); Qobuz client = Arc<RwLock<Option<QobuzClient>>> (unwrapped per access).
The vector store stays tokio::Mutex (held across awaits by the engine). No
dependency cycle (qbz-reco does not depend on qbz-core). qbz-core checks clean;
23 qbz-reco tests green.
cc
T5: 1:1 port of the artist_vectors SuggestionsEngine into qbz-reco (~880 lines;
structure matches the Tauri source function-for-function). generate_suggestions:
ensure each seed vector (builder.ensure_vector), gate on a non-empty combined
playlist vector, rank candidates by DIRECT summed relationship weight via
store.get_all_related_artists (NOT cosine/find_nearest, D3), then pull + dedup +
exclude tracks from Qobuz with the validate_qobuz_artist + has_incompatible_genre
gates and optional reason strings. Keeps Tauri's Arc<Mutex>/RwLock ownership
(Send-safe). DTO reconciliation: crate::api -> qbz_qobuz::QobuzClient +
qbz_models::Track (4 Qobuz calls mapped to real signatures, field-by-field).
Adds rand (0.10, workspace) + qbz-models deps. 23 qbz-reco tests green.
cc
T4: 1:1 port of the artist_vectors vector builder into qbz-reco. Keeps Tauri's
Arc<Mutex>/RwLock ownership of the store + MusicBrainz client/cache + Qobuz
client (NOT the plan's by-ref pattern): MusicBrainzCache holds a !Sync rusqlite
Connection, so a borrowed &cache held across the MB-API await would make the
spawned suggestions future !Send. The interleaved short-lived locking (drop the
guard before each await) is the faithful + Send-safe shape. Swaps only
crate::api::QobuzClient -> qbz_qobuz::QobuzClient (get_similar_artists ->
SearchResultsPage<Artist>); the MusicBrainz types already live in
qbz_integrations so extract_relationships ports verbatim. Drops the dead
resolve_qobuz_to_mbid (D3). 21 qbz-reco tests green.
cc
T3: 1:1 port of the artist_vectors vector store into qbz-reco. open_at(base)
opens <base>/cache/artist_vectors.db (WAL) with the 3-table schema kept
byte-identical (CREATE IF NOT EXISTS) for cross-frontend reuse. Ports the
in-memory artist index, get_or_create_idx, set_vector (delete-then-insert per
(artist,source) + metadata nnz), get_vector (SUM GROUP BY), has_fresh_vector,
get_artist_name, and the production ranking get_related_artists /
get_all_related_artists (SUM ORDER BY total_weight DESC). Drops the dead
find_nearest cosine path (D3) and the Tauri State/tokio wrapper (lifecycle in
the frontend/core per ADR-006). 4 store tests, 20 qbz-reco tests green.
cc
T2: 1:1 port of the artist_vectors RelationshipWeights (12 fields, Default, the
band_focused/similarity_focused presets, and the weight_for_mb_relation /
weight_for_source maps) with its tests. The presets are unused in production but
ported verbatim for parity (pub lib API, no dead-code warnings).
cc
New frontend-agnostic crate qbz-reco (ADR-006) for the playlist Suggested Songs
engine (sub-plan 2). T1: 1:1 port of the Tauri artist_vectors SparseVector
(sorted parallel index/value arrays, set/get, dot merge-join, magnitude/
normalize, serde) with its full test suite (13/13 green). Drops the dead
top_k_similar helper (its only caller find_nearest is dropped per epic D3);
keeps cosine_similarity for parity + tests but not for ranking.
cc
Add RecoStore::get_known_artist_ids (artists played >threshold OR favorited;
unit-tested) and union it into the network-discovery 'skip artists I already
know' filter. play_history stays the source of the (id, name) known set:
reco_events has no artist names and the schema is frozen to match Tauri, so
full consolidation (plan D2) would regress the name-based MB candidate filter.
This augments the id set with reco's richer plays+favorites signal instead.
cc
Reorder the resolved favorite albums so the reco-scored favorites lead (taste
order from the trained favorite_album scores), keeping unscored albums in their
original relative order. When reco is cold/disabled the row keeps the original
Qobuz order, so a fresh store never regresses. The reorder flows into the
Favorites, Rediscover, Radio and more-from-library seed (all share fav_albums).
cc
Wire the reco store into the For You favorite-albums branch:
- Genre backfill: when favorite albums resolve (full Album with genre), write
each (genre_id, genre_name) onto its reco events + album-meta via
spawn_blocking. Plays carry no genre, so this makes the engine's get_top_genres
non-empty (Tauri never backfilled, so its top-genres was dead).
- Rediscover: build_rediscover prefers the reco 'forgotten favorites' set
(favorited, not played in 30d, from the Tauri-shared events.db) when warm,
falling back to the local recents heuristic when cold so the row never empties
(non-regressing for fresh stores, better for Tauri-migrants).
cc
Two additive RecoStore queries with unit tests (all 8 reco_store tests green):
- get_forgotten_favorite_album_ids(limit, recency_days): favorite albums not
played within the window. Ported from Tauri db.rs:391-426 but adapted to the
integer created_at schema -- Tauri's datetime('now',..) string compare never
matched the integer column, so the recency filter is a numeric cutoff.
- update_genre_for_album(album_id, genre_id): backfills genre_id onto an
album's still-NULL events. Plays log no genre, so the frontend writes it back
on album resolution; this is what makes get_top_genres non-empty (Tauri
defined the backfill fns but never called them, so its top-genres was empty).
cc
mix_listened_seed_ids now prefers the reco store's scored continue-listening +
favorite track seeds (generous per-bucket limits, deduped, capped at 120) and
falls back to the local recents + Qobuz-favorites derivation when reco is
cold/disabled, so mixes never go empty. Call site unchanged. Drops the now
redundant dead_code allow on reco::home_seeds (W6 is its first consumer).
cc
Replace the 10 TODO(reco-v1) markers with PlaylistAdd logging, one event per
requested Qobuz track id:
- Qobuz->Qobuz (no-dup + dup-fallback), create-and-add online, dup-confirm
add-all and add-new-only, Qobuz->local, create-and-add local (Qobuz branch):
log the FULL requested ids (cloned before any dedup/insert consumes them),
with the Qobuz playlist id when the target is a Qobuz playlist.
- Local-ref adds (2 seams) and the playlist importer are NOT logged: local
refs are not resolvable Qobuz ids (same source gate as plays), and the
importer is a bulk external import Tauri never logged.
cc
Log a reco favorite event at each favorite-add seam, ADD-only and on network
success so un-favorites, rollbacks and bulk syncs never enter the signal:
- track-row heart (main.rs) + now-playing heart (queue.rs) -> track favorite
- album grid-add arm + album-header toggle -> album favorite
- artist follow -> artist favorite (Qobuz id parsed to u64)
Each logs via spawn_blocking off the async path. The album-toggle and artist
seams log from the async block, not the upgrade_in_event_loop UI-thread
closure (where spawn_blocking would panic).
cc
Fire RecoStore::train() fire-and-forget (spawn_blocking) right after the store
is opened on login and session-restore, mirroring Tauri's non-awaited
trainScores. Off-thread, default decay/weight params, no-op when reco is
disabled. Offline entry stays init-only.
cc
Wire the ported, unit-tested RecoStore engine into the session lifecycle and
log plays at the recents chokepoint.
- New crates/qbz/src/reco.rs: per-user store behind a process-global
Mutex<Option<RecoStore>> (mirrors fav_cache); helpers no-op when no session
is open. init_for_user/teardown, home_seeds reader, is_qobuz_source gate,
log_play_gated.
- Lifecycle: init on login/restore/offline-entry next to fav_cache; teardown
on logout.
- playback::record_recent logs each play via spawn_blocking (blocking SQLite
off the async path), gated Qobuz-catalog only (skip local/plex/ephemeral so
unresolvable ids never poison the home seeds; qobuz_download counts).
cc
Feature branches (slint-mvp) no longer auto-run the build on every push — that
burned minutes, and the qbz_ui compile is the expensive one. build-slint.yml now
auto-fires only on push to main; workflow_dispatch keeps it manually triggerable
on any branch.
cc
Adds cargo-deb / cargo-generate-rpm config so the release pipeline can fan out
.deb/.rpm from the prebuilt (stripped) binary — no Tauri bundler needed.
- [package.metadata.deb] + [package.metadata.generate-rpm] in crates/qbz.
- packaging/qbz.desktop (FHS) + packaging/qbz.png (icon) -> /usr/share/{applications,icons}.
- Runtime deps: $auto (ldd) + the dlopen'd GPU/Wayland/D-Bus stack listed by hand
(ldd can't see it). Validated in a 16 GB Ubuntu 24.04 VM: 37 MB .deb, 44 MB .rpm.
cc
Not every album ships a booklet and the in-app PDF reader was clumsy. The album
booklet button now DOWNLOADS the goody PDF (native save dialog, app HTTP client)
instead of rendering it in-app, and the MuPDF rasterizer is dropped entirely:
- crates/qbz/src/booklet.rs: reduced to set/clear URL + download_booklet (fetch
+ save dialog). Removed the reader (open/render/paging/zoom/rotate/close).
- main.rs: the ("album","booklet") action now calls download_booklet; removed the
BookletActions reader wiring block.
- Removed the qbz-booklet crate (MuPDF) from the workspace + qbz deps; Cargo.lock
drops mupdf/mupdf-sys. ~26 MB static MuPDF (~6 MB linked) + its heavy C build
are gone, lightening the build (more headroom under the 16 GB rustc wall).
AlbumBookletModal.slint + the BookletState/BookletActions globals are now unused
(left in place; remove in a UI cleanup pass that recompiles qbz-ui).
cc
The dev box is Gentoo/OpenRC with no systemd, hence no snapd, so it cannot
build or upload snaps. This pipeline keeps everything on GitHub-hosted Ubuntu
runners (which have snapd) instead:
- packaging/snap-slint/snapcraft.yaml: a `plugin: dump` recipe that packages a
PRE-BUILT qbz binary (no compilation), with the Slint runtime stack
(Vulkan/GL via the gnome extension, winit Wayland/X11, alsa/pipewire, mpris).
Kept separate from the Tauri snapcraft.yaml so neither clobbers the other.
- .github/workflows/release-snap.yml: job 1 compiles the binary on a 16 GB
runner using the same MIN-tier + 18 GB swap recipe as build-slint.yml; job 2
downloads it and runs snapcraft `dump` + snapcore/action-publish. The heavy
compile is on a free public runner; the snap packaging is on a runner that
has snapd — neither touches the OpenRC box.
Requires the SNAPCRAFT_STORE_CREDENTIALS secret (generate once via
`snapcraft export-login` on any snapd-capable host). The runtime confinement
(stage-packages/plugs for the non-GTK GPU stack) is a first cut and will need a
real `snapcraft build` + `snap run` on the runner to finalize; it cannot be
tested locally without snapd.
cc
The qbz_ui rustc (generated Slint UI, one ~1.6M-line module) is the build
wall: measured peak demand ~30 GB (RSS+Swap), and it is frontend-bound.
Codegen knobs barely move it (cu=256/opt=2 + -Z threads=1/jobs=1 shave only
~3 GB vs cargo defaults), so the build is made to FIT via RAM+swap, not tuned
down. Extracting feature crates out of the bin does not lower it either: the
bin peaks at only ~4.5 GB; qbz_ui is strictly upstream of it.
- Swap 8 -> 18 GB: 16 GB RAM + ~22 GB swap (~38 GB) comfortably exceeds the
~30 GB demand. 8 GB was an OOM risk (16+4+8 ~= 28 GB < 30 GB).
- Swatinem/rust-cache@v2 (crates -> target, shared-key, save-if slint-mvp):
a controller-only push restores the prebuilt qbz_ui rlib from cache and
rebuilds only the cheap qbz bin. This, not the peak, is the minute saver.
- Pin a dated nightly (was floating @nightly): rustc -V is part of the cache
key, so a floating nightly re-keyed the cache and invalidated every Cargo
fingerprint daily (the from-scratch-every-run waste).
- concurrency cancel-in-progress: a new push to slint-mvp cancels the older
in-flight build instead of stacking ~20-min runs.
cc
New shared crate qbz-slint-common (will also host the artwork primitives via a
dependency-inversion pass). toast.rs is a clean leaf over qbz-ui: only Slint
types (AppWindow, ToastKind, ToastState) + slint core (Timer/Weak). Moved
verbatim; the only edit is the import (`crate::` -> `qbz_ui::`). Bin re-exports
via `pub use qbz_slint_common::toast;` so all 154 call sites across 21 files are
unchanged. slint dep is `default-features = false` (adversarial review: a
default-features slint here would turn on the default renderer for the whole
build via feature unification). `cargo check -p qbz` green.
cc
Both are pure leaves (no bin-module refs, no Slint coupling). Moved verbatim
into qbz-text-utils. Caught by adversarial review: dates.rs needs chrono's
`unstable-locales` feature (Locale + format_localized) and an inline
`qbz_i18n::current_language()` ref (no `use` line — the qbz_models::Track
trap). Bin re-exports via `pub use qbz_text_utils::{dates, strip_html};` so the
14 call sites are unchanged. `cargo check -p qbz` green.
cc
First per-feature crate split off the qbz binary. `dac_wizard.rs` (794 LOC)
was the cleanest candidate: zero cross-feature module deps — it only used
qbz-ui generated types (AppWindow, DacWizardState, …), qbz-audio, qbz-models
and qbz-i18n. Moved verbatim into `qbz-dac-wizard/src/lib.rs` (import
`crate::` -> `qbz_ui::`); the bin now `use qbz_dac_wizard as dac_wizard;` so
its ~20 call sites in main.rs are unchanged. `cargo check -p qbz` green.
cc
Slint cannot split the .slint compilation across crates, but a Slint LIBRARY
crate exposes its generated Rust types to dependent crates (verified with a
minimal proof). So:
- NEW crate `qbz-ui` (lib): owns the whole .slint tree + build.rs + bundled
translations; `slint::include_modules!()` + the generated types (AppWindow,
MiniPlayerWindow, all globals/structs) are re-exported. Translation domain is
now `qbz-ui` (the .po files renamed accordingly).
- `qbz-slint` (bin) -> renamed to `qbz` (package + `[[bin]] name = "qbz"`),
reclaiming the binary name from the retired Tauri app. It depends on `qbz-ui`
and does `pub use qbz_ui::*;` so existing `crate::AppWindow` / `crate::*State`
references resolve unchanged.
This splits the single ~20 GB rustc into two crates (UI/codegen vs the 75k LOC
of logic) — the foundation for lower build peak, incremental caching, and the
upcoming per-feature crate extraction.
Also fixed for the move: qbz-i18n bundled-.po include paths, the font/WGSL
`include_bytes!`/`include_str!` paths (-> ../../qbz-ui/ui/), workspace members,
dev scripts (`-p qbz`), and the CI workflows. `cargo check -p qbz` is green.
cc
The GitHub-hosted private runner is 2 vCPU/8 GB and cannot build qbz-slint
(died at 1h42m). The dev box CAN, so a self-hosted runner (qbz-box) gives a
reliable CI artifact. Manual trigger; uncapped threads=2 (box-proven);
persistent work dir = incremental after first build.
cc
mupdf-sys (via qbz-booklet) links the system third-party libs; the build
got 21 min in and failed on a missing harfbuzz. Add the full mupdf system-lib
set so it links cleanly.
cc
The runner already ships an active /swapfile, so fallocate on it fails with
"Text file busy". Add the extra swap on a fresh path (/swap_extra) and guard
the whole swap block so a hiccup never fails the job — memory was never the
blocker (the prior run died on disk, not OOM).
cc
ubuntu-24.04 has no separate large /mnt disk — it's all on the 72 GB root
(~16 GB free), so the 12 GB swapfile + cargo target overflowed it (protobuf
failed with ENOSPC, not OOM — the build was memory-fine). Free ~25-30 GB of
unused preinstalled toolchains, drop swap to 8 GB, and keep the target on the
default path.
cc
Build-only workflow on ubuntu-24.04 with a 12 GB swapfile and the
lowest-memory rustc settings (serial frontend, codegen-units 256,
opt-level 2, one rustc at a time) so a stock 16 GB runner can compile the
Slint app. Triggers on push to slint-mvp and via workflow_dispatch.
cc
Adds the full keybindings system (26 actions, 5 categories, customizable
and persisted) plus the Ctrl+L "Open Qobuz Link" cross-platform resolver
to the Slint frontend, matching the Tauri implementation 1:1.
- New shared crate qbz-music-link: de-Tauri'd cross-platform link
resolver (Qobuz/Spotify/Apple/Tidal/Deezer/song.link via Odesli) behind
a QobuzSearchBridge trait. src-tauri left untouched.
- src/keybindings.rs: action model, winit shortcut grammar, conflict
detection, ui_prefs persistence, main-window + miniplayer dispatch.
- src/link_resolver.rs: controller + bridge over QbzCore.
- New globals + 3 modals (read-only cheatsheet, customize editor with key
capture, link resolver), hamburger menu entries, and a UiFocusState
text-input guard wired across the app's TextInputs.

The fixed threads=16/opt=3 release build SIGTERM'd at codegen whenever the
desktop held ~8-11 GB (30 GB box, no hibernation, hard-freezes on OOM). Now
scales rustc frontend threads + codegen-units + opt-level to MemAvailable
(FAST >=26G / SAFE 14-26G / MIN <14G), runs under cargo-capped with the cap
matched to free RAM, and adds FAST/THREADS/CODEGEN_UNITS/OPT/CAPPED/NORUN env
overrides. Verified: full release build completed at SAFE tier (threads=2
cgu=256 opt=3, capped ~19.7G) in 55m without freezing.
cc
The public getter was redundant: format-scoped completion gating reads the
download format_id internally via track_status_scoped (s.album_format_id), so the
accessor was never wired and only produced a dead_code warning. No behavior
change. cargo check -p qbz-slint exit-0 in 2m14s; the port code is now
warning-free (the remaining following_state/cached warnings are pre-existing,
unrelated to purchases).
cc
Closes the final-audit gaps for full 1:1 + standards compliance:
- Persist the 4 remaining purchase UI prefs (hide-unavailable, hide-downloaded,
quality-filter, region-notice-seen) per-machine in ui_prefs.json + startup seed,
so filter selections survive restart and the region notice does not reappear
(matches Tauri's persisted prefs).
- Translate the 4 controller toast/error strings into es/de/fr/pt (were
English-only; honors the 5-locale rule). Mexican/neutral Spanish.
- Explicit z:3000/3001 on the format-picker backdrop/popup + filter panel
(ADR-009 >= 3000; previously relied on declaration order).
cargo check -p qbz-slint exit-0.

Slice 12/13. Two persisted UI prefs (show_purchases, nav_tb_purchases, both
default false) in UiPrefs; Show-Purchases toggle drives the show-purchases flag
the S11 nav gates on; 'Purchases in title bar' toggle (nav_tb_purchases, disabled
without a custom titlebar). Implements the source-of-truth section 5.8 placement
truth table: sidebar entry shown iff S && !(T && TB), header entry iff S && T && TB
(closing the S11 per-feature-gating gap) so flipping the toggle moves the Purchases
entry between sidebar and header 1:1 with Tauri. on_appearance_bool persistence +
startup reseed. cargo check -p qbz-slint reached exit-0. Per-machine prefs
(consistent with other Slint appearance prefs).
cc
Slice 11/13. NavEntry::PurchaseDetail(String) + full routing (scope_for/
apply_entry, history recording + update_nav_flags on purchase-album clicks and
the Purchases route), session-restore-safe purchases (id-gated purchase-album),
conditional-mount guard + A.3 reactive reload (back/forward between two purchase
albums re-fetches). Sidebar ShoppingBag row + HeaderBar tabs (full+compact),
gated on show-purchases && !offline, active for both purchases + purchase-album.
nav.rs round-trip history test. Type-check clean (exit-0 not reachable on this
box; SIGTERM at metadata = memory limit).
cc
Restores the purchase-album detail mapper that the Slice-9 detail load path
(qbz-slint purchases.rs:2270) already references but which was left uncommitted
in the working tree (staged-list miss when committing S9). build_purchase_album
maps a fetched Album + purchase listing + downloaded ids + format map into the
detail payload (per-track + album downloaded flags, synthesized format options,
page counts). 5 unit tests; 30 offline-cache purchases tests green.
cc
Slice 10/13. A.2: per-track row play in both purchases views routes to
playback::play_track_now (single track, NO replacePlaybackQueue/setPlaybackContext)
instead of media_action play_track_in_context. A.1: Play-album confirmed on the
regular album fetch+queue path. New mirror_now_playing_to_purchases feeds both
purchases globals' active-track-id + playback-active from the now-playing refresh
(meta apply + poll tick). Folded Slice-9 review fixes: detail + list track titles
trimmed (formatTrackTitle parity), dead PurchaseDetailState.artwork-url removed.
Fixed E0308 (track_id u64). Front-end type-check clean (zero diagnostics).
