ci(release): build Windows NSIS installer on tag

Adds a build-windows job to the release workflow, cross-compiling the Windows NSIS installer from Linux via the builder image (MSVC target + cargo-xwin, no toolchain installs). Wires its artifacts into create-release alongside Linux and Android. TRACES: UR-003 | DR-004
feat(build): cross-platform desktop packaging; bump to 0.1.0

+# Desktop packaging (Linux, Arch, Windows)
+
+How to produce distributable desktop packages for JellyTau. All three flows can
+run in Docker so no host toolchain setup is required. Outputs land in `./dist`.
+
+## One builder image (shared with CI)
+
+The deb/rpm and Windows-cross flows build on the **unified registry builder**
+([../Dockerfile.builder](../Dockerfile.builder) →
+`gitea.tourolle.paris/dtourolle/jellytau-builder`), the same image CI uses. It
+carries every packaging tool: Android SDK/NDK, `rpm`/`file` (Linux bundler),
+`cargo-xwin` + `lld` + `llvm` + `nsis` + the `x86_64-pc-windows-msvc` rust target
+(Windows). There is **one** dependency source of truth — no per-stage tool
+installs.
+
+The desktop stages in [../Dockerfile](../Dockerfile) are thin `FROM
+${BUILDER_IMAGE}` environments; the actual build runs at container-run time on
+your bind-mounted source (like the `dev` service), so source edits need no image
+rebuild.
+
+**If you changed `Dockerfile.builder`** (e.g. added a tool), rebuild and push it
+first, or the packaging flows use the stale registry image:
+
+```bash
+scripts/build-builder-image.sh           # build + push :latest to the registry
+# ...or iterate locally without pushing:
+docker build -f Dockerfile.builder -t jellytau-builder:latest .
+BUILDER_IMAGE=jellytau-builder:latest bun run docker:build:windows
+```
+
+Arch uses a separate `archlinux` image ([../Dockerfile.arch](../Dockerfile.arch))
+because `makepkg` is Arch-specific — it is not part of the unified builder.
+
+| Target | Format | Docker command | Functional? |
+|--------|--------|----------------|-------------|
+| Debian/Ubuntu, Fedora | `.deb`, `.rpm` | `bun run docker:build:linux` | ✅ yes |
+| Arch Linux | `.pkg.tar.zst` | `bun run docker:build:arch` | ✅ yes |
+| Windows | NSIS installer + `.exe` | `bun run docker:build:windows` | ✅ yes (unsigned) |
+
+## Linux: deb + rpm
+
+Tauri's bundler produces these natively. The build runs on the existing Ubuntu
+builder image ([../Dockerfile](../Dockerfile), `desktop-linux-build` stage):
+
+```bash
+bun run docker:build:linux            # deb + rpm -> ./dist
+# or, on a host with the Tauri Linux deps installed:
+BUNDLES="deb,rpm" scripts/build-desktop-linux.sh
+```
+
+Runtime dependency: the app links libmpv (audio) and WebKitGTK (webview + HTML5
+transcoded video). The deb/rpm declare these.
+
+> Note: `appimage` is also a valid Tauri target if you want a portable bundle —
+> add it to `BUNDLES`.
+
+## Arch Linux: pacman package
+
+**Tauri has no `pacman` bundle target** (as of tauri-cli 2.9.x — valid targets
+are deb/rpm/appimage/msi/nsis/app/dmg). So we ship a hand-written PKGBUILD in
+[../packaging/arch/PKGBUILD](../packaging/arch/PKGBUILD) and build it with
+`makepkg` on an Arch base image ([../Dockerfile.arch](../Dockerfile.arch)):
+
+```bash
+bun run docker:build:arch             # .pkg.tar.zst -> ./dist
+```
+
+The PKGBUILD is AUR-ready: swap its `source=()` for a release tarball/VCS URL to
+publish. Runtime deps: `webkit2gtk-4.1`, `mpv`, `gtk3`, `libayatana-appindicator`.
+
+`makepkg` refuses to run as root, so the Docker stage builds as a non-root
+`builder` user. Because the image `COPY`s the source at build time, the
+`arch-build` compose service does **not** bind-mount the repo — rebuild the image
+to pick up source changes.
+
+## Windows: NSIS installer cross-compiled from Linux
+
+Produces a working (unsigned) NSIS installer + `.exe` via the official Tauri
+cross-compile path — the `x86_64-pc-windows-msvc` target driven by `cargo-xwin`.
+Video plays via WebView2 and audio via the webview `<audio>` backend. See
+[build-windows.md](build-windows.md) for the full explanation.
+
+```bash
+bun run docker:build:windows                     # NSIS installer + .exe -> ./dist
+WIN_BUNDLES=none bun run docker:build:windows     # exe only, skip bundling
+```
+
+The Docker `windows-cross` stage is a thin layer over the builder, which carries
+`cargo-xwin` + `lld` + `llvm` + `nsis` + the `x86_64-pc-windows-msvc` target.
+Cross-compilation is Tauri's "last resort" path (less tested than building on
+Windows); a `windows-latest` CI job is the fallback if it misbehaves.

+# Windows build
+
+JellyTau targets Linux and Android primarily, but a working Windows build —
+including an **NSIS installer cross-compiled from Linux** — is produced by the
+Docker tooling. It is not yet a first-class release target (no code signing / CI
+job / SMTC lockscreen), but it runs and plays media.
+
+## How playback works on Windows
+
+- **Video** — renders through the webview HTML5 `<video>` element (hls.js) on
+  *every* platform; on Windows that is WebView2 (Chromium/Edge), which plays HLS +
+  h264 fine. No Windows-specific code.
+- **Audio-only (music)** — the native audio backends are libmpv (Linux) and
+  ExoPlayer (Android); neither exists on Windows. Instead
+  `create_player_backend()` in [../src-tauri/src/lib.rs](../src-tauri/src/lib.rs)
+  uses `WebviewAudioBackend` on non-Linux/non-Android targets: it hands the stream
+  URL to a webview `<audio>` element (see
+  [../src/lib/services/webviewAudio.ts](../src/lib/services/webviewAudio.ts)),
+  which reports state back through the same `player_report_*` round-trip the video
+  path uses. Pure Rust + Tauri events.
+
+## Cross-compiling from Linux (MSVC + cargo-xwin)
+
+We use the [official Tauri cross-compile path](https://v2.tauri.app/distribute/windows-installer/):
+the **MSVC** target (`x86_64-pc-windows-msvc`) driven by
+[`cargo-xwin`](https://github.com/rust-cross/cargo-xwin), which downloads the MSVC
+CRT / Windows SDK headers and links with `lld`. MSVC is the target Tauri
+officially supports for Windows (mingw/GNU is not), and — unlike GNU — it lets the
+Tauri CLI bundle the **NSIS installer from a Linux host**.
+
+> Why not mingw/GNU? The GNU target *does* link a valid `.exe`, but the Tauri CLI
+> gates `--bundles` by the host OS unless it recognizes a real Windows build.
+> `--runner cargo-xwin --target x86_64-pc-windows-msvc` is what flips it into
+> Windows mode and enables the `nsis`/`msi` bundlers on Linux.
+
+The builder image ([../Dockerfile.builder](../Dockerfile.builder)) bakes in the
+whole toolchain: the `x86_64-pc-windows-msvc` rust target, `cargo-xwin`, `lld`,
+`llvm`, and `nsis`.
+
+```bash
+bun run docker:build:windows            # NSIS installer + .exe -> ./dist
+WIN_BUNDLES=none bun run docker:build:windows   # exe only, skip bundling
+```
+
+Or directly on a host that has the toolchain:
+
+```bash
+scripts/build-windows-cross.sh                    # nsis installer + exe
+WIN_BUNDLES=none scripts/build-windows-cross.sh   # exe only
+```
+
+Under the hood the build runs:
+
+```bash
+tauri build --runner cargo-xwin --target x86_64-pc-windows-msvc --bundles nsis
+```
+
+Outputs:
+- `.exe` — `src-tauri/target/x86_64-pc-windows-msvc/release/jellytau.exe`
+- NSIS installer — `.../release/bundle/nsis/*-setup.exe`
+
+(both copied to `./dist` when `OUTPUT_DIR` is set).
+
+## Caveats
+
+- **Cross-compilation is a last resort** per Tauri's own docs — it's less tested
+  than building on Windows. If it misbehaves, a `windows-latest` CI job or a
+  Windows VM building natively (`tauri build --bundles nsis`) is the fallback.
+- **Code signing is not wired up** — the installer is unsigned, so Windows
+  SmartScreen will warn on first run.
+
+## Outstanding for a first-class Windows release
+
+1. Gapless/crossfade + SMTC (lockscreen) — currently no-ops in the webview audio
+   path.
+2. Downloaded (`Local` source) file playback needs `convertFileSrc` on the
+   frontend; streaming works today.
+3. Code signing + a Windows packaging CI job.

+# Spec: Audio equalizer
+
+**Status:** Accepted
+**Requirements:** UR-027 → DR-030 (EQ UI), IR-020 (MPV EQ integration).
+**UX spec:** n/a (extends the Settings › Audio section, ux-flows §8.1 instant-apply).
+**Supersedes / revises:** —
+
+## Summary
+
+Add a graphic audio equalizer to playback. Users pick a preset (Flat, Rock,
+Pop, Jazz, Classical, Bass Boost, Treble Boost, Vocal) or set custom per-band
+gains, from a new block in Settings › Audio. On Linux the gains apply live via
+MPV's audio-filter chain; the settings persist and re-apply on the next track
+and at startup, exactly like crossfade/gapless/normalize do today. Android is a
+no-op for now (documented parity gap, same as those three features).
+
+## Motivation
+
+UR-027 is one of the few still-unbuilt audio features. The audio-settings
+pipeline it needs already exists — `AudioSettings` + `set_audio_settings` on the
+`PlayerBackend` trait, the `player_set_audio_settings` command, and the Settings
+› Audio UI with instant-apply. Crossfade, gapless, and volume normalization all
+ride that pipeline. The equalizer is the same shape: N more fields on
+`AudioSettings`, an `af` filter on the MPV backend, one more block in the
+settings panel. No new command, no new state machine.
+
+## Layer assignment
+
+| Logic / responsibility | Layer | Why it belongs there |
+|------------------------|-------|----------------------|
+| EQ band count, centre frequencies, gain range/clamping | Rust | Domain of the audio engine; the bands must match what the MPV filter expects. Changing the DSP must not require a frontend change. |
+| Preset name → per-band gain curve | Rust | A preset *is* a domain gain curve, not a label. It changes with the audio engine's band layout, never with the UI. Placing it in the frontend would be the scoped-search taxonomy mistake again (values that look like config but are domain data). |
+| Translating gains → MPV `af` filter string | Rust | Platform playback detail; lives with the other `set_audio_settings` filter code in `mpv_backend.rs`. |
+| Persisting the chosen settings, re-pushing on load | Rust/existing | Same path crossfade/etc. already use; the controller re-applies `AudioSettings` per track. |
+| Rendering band sliders, the preset chips, live readouts | Frontend | Pure presentation; changes only if the settings UI is redesigned. |
+| Which preset chip is highlighted; instant-apply on change | Frontend | Presentation/input handling (UR-057), the same as the normalize preset picker. |
+
+Tie-breaker note: the preset→curve map is the one tempting boundary leak. It goes
+in Rust because a preset is a set of band gains defined *by the band layout*,
+which is an engine property. The frontend only ever names a preset and renders
+the resulting gains; it never defines them.
+
+## Design
+
+### `AudioSettings` (Rust, `settings.rs`)
+
+Add two fields (both `#[serde(rename_all = "camelCase")]` via the existing
+struct attribute):
+
+```rust
+/// Equalizer enabled. When false, no `af` EQ filter is applied.
+pub equalizer_enabled: bool,
+/// Per-band gains in dB, one per FIXED band (see EQ_BANDS). Length is
+/// validated/normalised to EQ_BANDS.len(); clamped to [-12, +12] dB.
+pub equalizer_bands: Vec<f32>,
+```
+
+Fixed 10-band ISO layout (domain constant in `settings.rs`):
+
+```rust
+pub const EQ_BANDS: [f32; 10] =
+    [31.0, 62.0, 125.0, 250.0, 500.0, 1000.0, 2000.0, 4000.0, 8000.0, 16000.0];
+pub const EQ_GAIN_MIN: f32 = -12.0;
+pub const EQ_GAIN_MAX: f32 = 12.0;
+```
+
+- `Default`: `equalizer_enabled: false`, `equalizer_bands: vec![0.0; 10]` (flat).
+- New `with_equalizer_normalised(self)` clamps each gain to `[EQ_GAIN_MIN,
+  EQ_GAIN_MAX]` and pads/truncates the vec to 10 bands. Applied in the command
+  alongside `with_crossfade_clamped` (add that call too — it's currently missing).
+- Backward compat: both fields `#[serde(default)]` so old persisted JSON loads.
+
+### Presets (Rust, `settings.rs`)
+
+```rust
+#[derive(specta::Type, Serialize, Deserialize, Clone, Copy, PartialEq)]
+#[serde(rename_all = "camelCase")]
+pub enum EqPreset { Flat, Rock, Pop, Jazz, Classical, BassBoost, TrebleBoost, Vocal }
+
+impl EqPreset {
+    /// The 10-band gain curve (dB) for this preset.
+    pub fn gains(&self) -> [f32; 10] { /* table */ }
+}
+```
+
+Preset selection is a *frontend* convenience: tapping a chip sets
+`equalizer_bands = preset.gains()` and pushes settings. The curve tables live in
+Rust; the frontend reads them via a tiny `player_get_eq_presets` command
+returning `Vec<(EqPreset, Vec<f32>)>` (or a map), so the frontend never encodes
+the numbers. (If exposing the whole table is awkward through specta, expose
+`player_eq_preset_gains(preset) -> Vec<f32>` instead — pick at implement time.)
+
+### MPV application (Rust, `mpv_backend.rs::set_audio_settings`)
+
+Build an `equalizer` / `anequalizer` filter from the bands and set the `af`
+property. When `equalizer_enabled` is false or all gains are 0, clear the EQ
+filter (leave any other `af` entries intact). Use `af add`/`af remove` or a
+rebuilt `af` string; keep it isolated so it doesn't stomp a future crossfade
+filter. Errors map to `PlayerError` like the gapless code.
+
+### No new persistence table
+
+`AudioSettings` is already round-tripped by the frontend settings store and
+re-pushed via `player_set_audio_settings` on change and on load. The two new
+fields ride along. `NullBackend`/Android inherit the trait default (no-op).
+
+### Wire summary
+
+- Command names unchanged: `player_set_audio_settings`,
+  `player_get_audio_settings` (now carry the EQ fields).
+- New (optional) read-only command for preset curves — kebab n/a (it's a
+  command): `player_get_eq_presets` (or `player_eq_preset_gains`).
+- Regenerate `bindings.ts` from the Rust types; never hand-edit.
+
+## Out of scope
+
+- Android/ExoPlayer EQ (parity gap tracked with crossfade/gapless/normalize).
+- Per-track or per-library EQ profiles — one global profile only.
+- Automatic loudness/room correction; only manual bands + presets.
+- Changing the crossfade/normalize TODOs in `set_audio_settings` beyond wiring
+  the missing `with_crossfade_clamped` call.
+
+## Acceptance criteria
+
+- [ ] Settings › Audio has an Equalizer block: enable toggle, preset chips, 10
+      band sliders with live dB readouts, instant-apply (no Save button).
+- [ ] Choosing a preset sets the bands from the Rust-defined curve; editing a
+      band switches the highlighted preset to "Custom" (frontend-only label).
+- [ ] Gains clamp to [-12, +12] dB; the band vector always normalises to 10.
+- [ ] On Linux, enabling EQ audibly changes output and persists across tracks
+      and app restart; disabling clears the filter without affecting other audio.
+- [ ] Old persisted settings (no EQ fields) load without error, defaulting flat.
+- [ ] `bun run check` and `bun run test` pass.
+- [ ] `cargo fmt` clean, `cargo clippy` clean, `bun run test:rust` passes.
+- [ ] `bun run check:boundary` passes (no preset curve numbers in the frontend).
+- [ ] New requirement-implementing code carries `// TRACES:` comments.
+- [ ] `bindings.ts` regenerated.
+
+## Testing
+
+- Rust (`settings.rs`): default is flat + disabled; `with_equalizer_normalised`
+  clamps out-of-range gains and pads/truncates band length; serialization
+  round-trips the camelCase fields; backward-compat load of pre-EQ JSON; each
+  preset returns a 10-length curve; Flat is all zeros.
+- Rust IPC param naming for any new command (camelCase rule per CLAUDE.md).
+- Frontend (`settings` page or an extracted helper): selecting a preset sets the
+  expected band array; editing a band flips the label to Custom; enable toggle
+  gates the sliders. Keep DSP untested on the frontend (it's Rust's).
+
+## TRACES
+
+- `AudioSettings` EQ fields + normalise + presets: `UR-027 | DR-030` (+ unit tests)
+- MPV EQ filter application: `UR-027 | IR-020`
+- Settings EQ UI block: `UR-027 | DR-030`
+- Preset-curve command: `UR-027 | DR-030`
+
+## Notes for the implementer
+
+- A parallel Claude session is active in this repo (it has touched
+  `tauri.conf.json`, `Dockerfile`, `package.json`, home components, and added
+  build scripts, and the Rust build is currently broken by its
+  `tauri.conf.json` bundle-target change). `git diff` before "repairing"
+  anything you didn't write; keep EQ changes isolated to `settings.rs`,
+  `mpv_backend.rs`, `backend.rs` (trait default already covers it),
+  `commands/player/settings.rs`, and the settings page.
+- Mirror the volume-normalization block in the settings page for the toggle +
+  preset-picker pattern; mirror the gapless code in `set_audio_settings` for the
+  MPV property handling.
+- Confirm the exact MPV filter name available in the linked libmpv
+  (`equalizer` vs `anequalizer`/`superequalizer`) before committing the filter
+  string; gate cleanly if unavailable.

 ### 5B.2 Episode Focus View — section order

@@ -695,6 +698,38 @@ The same principle as §5B.2: **episodes come before cast and similar shows.**
 The reason a user opens a series page is to pick an episode; discovery content
 is secondary and sits underneath.

+### 5B.5 Home-card interaction — tap opens, long-press plays
+
+Cards on the Home screen carousels (Next Movie, Next Episode, Continue
+Watching, Recently Added, …) **do not play on tap.** A plain tap opens the
+item; playback is the deliberate, second gesture.
+
+| Card kind | Tap (short) | Long-press (~500 ms hold) |
+|-----------|-------------|---------------------------|
+| Movie | Movie detail page (`/library/<id>`) | Confirm → play now (`/player/<id>`) |
+| Episode | Series Episode Focus View (`/library/<seriesId>?episode=<id>`, per §5B.1) | Confirm → play now (`/player/<id>`) |
+| Series / Season / Album / Artist / Playlist / Folder | Detail page (`/library/<id>`) | Same as tap (no single "play now" target) |
+| Channel / live leaf | Player (`/player/<id>`) — no detail page exists | Confirm → play now |
+
+Rationale and rules:
+
+- **Tap is navigation, not commitment.** Previously a tap on a movie/episode
+  jumped straight into the player, which made it easy to lose your place in a
+  half-watched item or start a stream you only meant to inspect. Tap now lands
+  on the detail/focus page, where Play is an explicit button.
+- **Long-press is the shortcut for "just play it."** It surfaces a native
+  confirm (`Play "<name>" now?`) before starting playback, so an accidental
+  hold never blows away a resume position silently.
+- **The long-press must not fight the carousel.** Detection cancels if the
+  pointer moves more than ~10 px (a horizontal scroll of the row), so holding
+  to scroll never triggers play.
+- **Episodes still obey §5B.1** — a home tap on an episode opens the series
+  Focus View, never a bare Episode page, so the series context loads.
+
+This behavior lives in `MediaCard` (`onLongPress` prop + pointer-based
+detection) so any surface can opt in; today the Home carousels are the only
+opt-in. Grids and other surfaces keep tap-to-open with no long-press.

+//! Webview audio backend — audio-only playback for platforms without a native
+//! audio backend (currently Windows).
+//!
+//! ## Why this exists
+//! All *video* already renders through the webview HTML5 `<video>` element on
+//! every platform (see `VideoPlayer.svelte`); libmpv/ExoPlayer only ever drive
+//! *audio-only* (music) playback. On Windows there is no native audio backend,
+//! so `create_player_backend()` used to fall back to `NullBackend` and music was
+//! silent.
+//!
+//! This backend fills that gap without any C dependency (so it still
+//! cross-compiles from Linux): instead of decoding audio itself, it hands the
+//! stream URL to a frontend `<audio>` element via a `WebviewAudioLoad` event and
+//! then drives play/pause/seek/stop through `ControlCommand` events — exactly the
+//! round-trip the HTML5 video path already uses. The `<audio>` element reports
+//! its real state/position back through the `player_report_*` commands, so the
+//! Rust `PlayerController` remains the single source of truth (the controller's
+//! `report_html5_*` methods fold those reports into the normal event pipeline).
+//!
+//! Because the reported state flows through the event pipeline (not through this
+//! backend's `position()`/`state()` pollers — the timer loop does not poll the
+//! backend for HTML5-rendered media), this backend only needs to keep a
+//! best-effort local mirror for direct `player_get_state` queries.

Windows cross-compiles from Linux via the official Tauri path — the x86_64-pc-windows-msvc target driven by cargo-xwin — and produces an NSIS installer (nsis via tauri.conf.json targets, since the CLI rejects --bundles nsis on a Linux host). Verified end to end: builds jellytau.exe + jellytau_x64-setup.exe. Unifies everything on one registry builder image (Dockerfile.builder): Android SDK/NDK, rpm/file, clang(+clang-cl)/lld/llvm/nsis, cargo-xwin and the msvc target. Packaging tools sit in a trailing layer so tool changes rebuild in ~1min instead of ~15. Desktop stages are thin FROM ${BUILDER_IMAGE} layers; Arch uses a separate archlinux image. CLAUDE.md: CI must install no system toolchains — everything lives in the image. Bumps version 0.0.18 -> 0.1.0 (Windows support + webview audio + equalizer).

dtourolle	d4e2cd120c	feat(player): webview audio backend for platforms without a native one Adds WebviewAudioBackend, used on non-Linux/non-Android targets (e.g. Windows) where there is no libmpv/ExoPlayer. Instead of decoding, it emits a WebviewAudioLoad event with the stream URL; a frontend <audio> element (WebviewAudioAdapter + webviewAudio service) plays it and reports state/position back through the existing player_report_* round-trip, so the Rust PlayerController stays the single source of truth. Play/pause/ seek reach the element via the existing ControlCommand event. All video already renders in the webview on every platform, so this completes audio-only playback for Windows (video via WebView2, audio via <audio>). Pure Rust + Tauri events, so it still cross-compiles from Linux. Regenerates bindings.ts (adds webview_audio_load; also carries the equalizer EQ bindings).

dtourolle	c543f90ad3	feat(audio): graphic equalizer with presets and custom bands Adds a 10-band graphic equalizer to AudioSettings (enabled flag + per-band dB gains, normalised to 10 entries and clamped to range). Presets return gain curves; the settings page gains EQ UI. libmpv applies the filter on Linux (Android parity pending). Old persisted settings without EQ fields load as disabled + flat. Also includes the requirements/traceability/ux-flows doc updates for this feature and the home long-press routing (UR-058/DR-087). TRACES: UR-027 \| IR-020, DR-030 \| UT-079, UT-080, UT-081, UT-082	2026-07-24 23:49:13 +02:00
dtourolle	589f08b873	feat(home): tap opens detail, long-press plays from home cards Home carousel cards route a tap to the item's detail / Episode Focus View and a ~500ms long-press to a confirm-then-play flow. MediaCard gains an onLongPress prop with pointer-based detection (cancelled on >10px move so carousel scroll is unaffected, trailing click suppressed). Episode taps route to /library/<seriesId>?episode=<id>; the bare-episode detail page links back to its parent series/season. TRACES: UR-058 \| DR-087	2026-07-24 23:49:03 +02:00
dtourolle	e2c9d68311	docs(downloads): mark UR-055/056 Done; fix colliding UT ids The browsable Downloaded library + Transfers split + on-disk usage (`f25deba`, plus today's grouping/perf fixes) fully implement UR-055 and UR-056, but the requirements doc still listed them and DR-081..085 as Planned. Flip to Done. Also fix UT-id collisions: the downloaded-browse and formatBytes tests reused UT-046..050 (already assigned to smart-cache/playlist tests in the matrix). Reassign to UT-071..078 and register them in §4, including the new music/TV container-rollup and orphan-leaf regression tests.	2026-07-24 22:22:43 +02:00
dtourolle	57b24f8c74	fix(offline): Downloaded browse groups by container and loads on large libraries Two bugs on the Downloaded browse surface (UR-055/UR-056): 1. Grouping — browsing a downloaded library listed individual leaves (songs, episodes) instead of their containers. The library-level match in `get_downloaded_items` selected every downloaded item on the server; add a NOT EXISTS clause so the top level shows only albums/series/movies, with leaves still reachable by drilling in. Regression tests for music + TV. 2. "Loading your downloads…" hung on large libraries. The disk-usage partiality query did an OR-based self-join over the entire synced catalog (O(items^2), unindexable). Narrow it to downloaded containers first via a CTE, and add the missing idx_items_season index (migration 020 + base schema) — parent_id/album_id/series_id were already indexed. Also annotate the existing backend tests that cover the IT-016/IT-017 end-to-end offline-listing scenarios with their trace IDs.	2026-07-24 21:42:12 +02:00
dtourolle	6391720d23	docs(offline): mark UR-052 offline-listing feature and its tests Done The DR-079/DR-080 root-cause fixes for issue #10 landed in 8f4f651; the requirements doc still listed UR-052 (and DR-078/079/080, UT-068/069/070, IT-016/017) as Broken/Partial/Pending. Flip them to Done and regenerate the traceability matrix. Existing backend tests already cover the IT-016/017 end-to-end scenarios (annotated with their IDs in the code commits).	2026-07-24 21:41:57 +02:00
dtourolle	90f03dd142	fix(player): show background-audio button on all Android video playback 🏗️ Build and Test JellyTau / Run Tests (push) Successful in 11m49s Details Publish Documentation / Build & publish docs to gitea-pages (push) Successful in 10m18s Details Traceability Validation / Check Requirement Traces (push) Successful in 1m2s Details Build & Release / Run Tests (push) Successful in 10m46s Details 🏗️ Build and Test JellyTau / Android Compile Check (push) Successful in 7m16s Details Build & Release / Build Linux (push) Successful in 24m59s Details Build & Release / Build Android (push) Successful in 33m5s Details Build & Release / Create Release (push) Successful in 17s Details The audio-only (background-audio) button was gated on the AndroidBackgroundAudio JS-bridge probe, resolved once as a const at mount. The bridge is injected into the WebView asynchronously and races component mount, so on some loads the probe returned false and never recovered, hiding the button on 'some videos' at random. Gate on platform() === 'android' instead (synchronous, stable), matching the convention in VolumeControl. toggleBackgroundAudio() already no-ops if the bridge is momentarily absent. Bump version to 0.0.18.	2026-07-24 20:32:08 +02:00
