+
+## Vue d'ensemble
+
+Une `MusicSource` est une abstraction qui représente une source de contenu musical dans PMOMusic. Elle peut être :
+
+- **Dynamique (FIFO)** : Radio Paradise, streaming radio, playlists live
+- **Statique** : Albums Qobuz, bibliothèque locale, playlists fixes
+
+Le trait `MusicSource` définit une interface unifiée pour :
+- La navigation UPnP ContentDirectory (browse)
+- La résolution d'URI audio (avec cache)
+- La gestion de playlists FIFO (pour les sources dynamiques)
+- Le suivi des changements (update_id, last_change)

+
+## Implémentation du trait MusicSource
+
+### 1. Informations de base
+
+Chaque source doit fournir :
+
+```rust
+use pmosource::{async_trait, MusicSource};
+
+#[derive(Clone, Debug)]
+pub struct MyMusicSource {
+    // Champs internes
+}
+
+#[async_trait]
+impl MusicSource for MyMusicSource {
+    fn name(&self) -> &str {
+        "Ma Source Musicale"  // Nom affiché dans l'UI
+    }
+
+    fn id(&self) -> &str {
+        "my-music-source"  // ID unique (format: lowercase-kebab-case)
+    }
+
+    fn default_image(&self) -> &[u8] {
+        // Logo WebP 300x300px inclus dans le binaire
+        include_bytes!("../assets/default.webp")
+    }
+
+    fn default_image_mime_type(&self) -> &str {
+        "image/webp"  // Toujours WebP
+    }
+}
+```
+
+**Règles :**
+- `id()` doit être unique parmi toutes les sources
+- `id()` doit être en lowercase-kebab-case
+- `default_image()` doit être un WebP 300x300px
+
+### 2. Navigation ContentDirectory
+
+#### 2.1 Container racine
+
+```rust
+async fn root_container(&self) -> Result<Container> {
+    Ok(Container {
+        id: self.id().to_string(),  // "my-music-source"
+        parent_id: "0".to_string(),  // Toujours "0" pour la racine
+        restricted: Some("1".to_string()),
+        child_count: None,  // Optionnel
+        searchable: Some("1".to_string()),
+        title: self.name().to_string(),
+        class: "object.container".to_string(),
+        artist: None,
+        album_art: None,
+        containers: vec![],
+        items: vec![],
+    })
+}
+```
+
+#### 2.2 Browse
+
+La méthode `browse()` est le cœur de la navigation :
+
+```rust
+async fn browse(&self, object_id: &str) -> Result<BrowseResult> {
+    match self.parse_object_id(object_id) {
+        ObjectIdType::Root => {
+            // Retourner les sous-containers principaux
+            let containers = vec![
+                self.build_albums_container(),
+                self.build_playlists_container(),
+                self.build_favorites_container(),
+            ];
+            Ok(BrowseResult::Containers(containers))
+        }
+
+        ObjectIdType::Album { album_id } => {
+            // Retourner le container + ses tracks
+            let album_container = self.build_album_container(&album_id);
+            let tracks = self.get_album_tracks(&album_id).await?;
+            Ok(BrowseResult::Mixed {
+                containers: vec![album_container],
+                items: tracks,
+            })
+        }
+
+        ObjectIdType::Track { track_id } => {
+            // Retourner les détails d'un track
+            let track = self.get_track_item(&track_id).await?;
+            Ok(BrowseResult::Items(vec![track]))
+        }
+
+        _ => Err(MusicSourceError::ObjectNotFound(
+            format!("Unknown object: {}", object_id)
+        ))
+    }
+}
+```
+
+**Schema d'Object ID recommandé :**
+
+```
+<source-id>                              # Racine
+<source-id>:albums                       # Container albums
+<source-id>:album:<album_id>             # Album spécifique
+<source-id>:track:<track_id>             # Track spécifique
+<source-id>:playlist:<playlist_id>       # Playlist spécifique
+```
+
+**Types de BrowseResult :**
+- `Containers(Vec<Container>)` : Liste de containers (navigation)
+- `Items(Vec<Item>)` : Liste de tracks (lecture)
+- `Mixed { containers, items }` : Les deux (album avec tracks)
+
+#### 2.3 Résolution d'URI
+
+```rust
+async fn resolve_uri(&self, object_id: &str) -> Result<String> {
+    // Étape 1 : Vérifier le cache audio
+    if let Some(cached_pk) = self.get_cached_audio_pk(object_id).await {
+        return Ok(format!("{}/audio/flac/{}", self.base_url, cached_pk));
+    }
+
+    // Étape 2 : Retourner l'URI originale
+    match self.parse_object_id(object_id) {
+        ObjectIdType::Track { track_id } => {
+            let stream_url = self.get_stream_url(&track_id).await?;
+            Ok(stream_url)
+        }
+        _ => Err(MusicSourceError::UriResolutionError(
+            format!("Cannot resolve URI for: {}", object_id)
+        ))
+    }
+}
+```
+
+**Ordre de résolution :**
+1. Cache audio local (si disponible)
+2. URI originale (API streaming, fichier local, etc.)
+
+### 3. Support FIFO (sources dynamiques)
+
+Si votre source est dynamique (radio, streaming live) :
+
+```rust
+use pmoplaylist::PlaylistManager;
+use std::sync::Arc;
+use tokio::sync::RwLock;
+
+#[derive(Clone)]
+pub struct RadioSource {
+    playlist_id: String,
+    update_counter: Arc<RwLock<u32>>,
+    last_change: Arc<RwLock<SystemTime>>,
+}
+
+#[async_trait]
+impl MusicSource for RadioSource {
+    fn supports_fifo(&self) -> bool {
+        true  // Cette source utilise une FIFO
+    }
+
+    async fn append_track(&self, track: Item) -> Result<()> {
+        // Récupérer le gestionnaire de playlist
+        let manager = PlaylistManager();
+        let writer = manager
+            .get_persistent_write_handle(self.playlist_id.clone())
+            .await
+            .map_err(|e| MusicSourceError::PlaylistError(e.to_string()))?;
+
+        // Extraire le PK depuis l'URI du track
+        let pk = self.extract_pk_from_item(&track)?;
+
+        // Ajouter à la playlist
+        writer
+            .push_lazy(pk)
+            .await
+            .map_err(|e| MusicSourceError::PlaylistError(e.to_string()))?;
+
+        // Incrémenter update_id
+        self.bump_update_counter().await;
+
+        Ok(())
+    }
+
+    async fn remove_oldest(&self) -> Result<Option<Item>> {
+        let manager = PlaylistManager();
+        let reader = manager
+            .get_read_handle(&self.playlist_id)
+            .await
+            .map_err(|e| MusicSourceError::PlaylistError(e.to_string()))?;
+
+        // Récupérer le plus ancien
+        let items = reader.to_items(1).await
+            .map_err(|e| MusicSourceError::PlaylistError(e.to_string()))?;
+
+        if let Some(item) = items.first() {
+            // Adapter l'item au schéma de la source
+            let adapted = self.adapt_item_to_schema(item.clone());
+            self.bump_update_counter().await;
+            Ok(Some(adapted))
+        } else {
+            Ok(None)
+        }
+    }
+
+    async fn update_id(&self) -> u32 {
+        *self.update_counter.read().await
+    }
+
+    async fn last_change(&self) -> Option<SystemTime> {
+        Some(*self.last_change.read().await)
+    }
+
+    async fn get_items(&self, offset: usize, count: usize) -> Result<Vec<Item>> {
+        let manager = PlaylistManager();
+        let reader = manager
+            .get_read_handle(&self.playlist_id)
+            .await
+            .map_err(|e| MusicSourceError::PlaylistError(e.to_string()))?;
+
+        // Récupérer les items
+        let items = reader
+            .to_items(count)
+            .await
+            .map_err(|e| MusicSourceError::PlaylistError(e.to_string()))?;
+
+        // Adapter au schéma de la source
+        let adapted = items.into_iter()
+            .map(|item| self.adapt_item_to_schema(item))
+            .collect();
+
+        Ok(adapted)
+    }
+}
+
+impl RadioSource {
+    async fn bump_update_counter(&self) {
+        let mut counter = self.update_counter.write().await;
+        *counter = counter.wrapping_add(1).max(1);
+        let mut last = self.last_change.write().await;
+        *last = SystemTime::now();
+    }
+}
+```
+
+**Points clés :**
+- Utiliser `pmoplaylist::PlaylistManager` singleton
+- Incrémenter `update_id` à chaque modification
+- Mettre à jour `last_change` à chaque modification
+- Adapter les IDs des items au schéma de la source
+
+### 4. Support statique (albums, bibliothèques)
+
+Si votre source est statique (catalogue, albums) :
+
+```rust
+#[async_trait]
+impl MusicSource for CatalogSource {
+    fn supports_fifo(&self) -> bool {
+        false  // Pas de FIFO
+    }
+
+    async fn append_track(&self, _track: Item) -> Result<()> {
+        Err(MusicSourceError::NotSupported(
+            "This source is read-only".to_string()
+        ))
+    }
+
+    async fn remove_oldest(&self) -> Result<Option<Item>> {
+        Ok(None)  // Pas de suppression
+    }
+
+    async fn update_id(&self) -> u32 {
+        0  // Jamais de changement
+    }
+
+    async fn last_change(&self) -> Option<SystemTime> {
+        None  // Pas de suivi des changements
+    }
+
+    async fn get_items(&self, offset: usize, count: usize) -> Result<Vec<Item>> {
+        // Retourner une liste paginée depuis le catalogue
+        self.get_catalog_items(offset, count).await
+    }
+}
+```
+
+## Patterns d'implémentation
+
+### Pattern 1 : Source dynamique avec FIFO (Radio Paradise)
+
+**Caractéristiques :**
+- Flux continu de tracks
+- Capacité limitée (50-100 tracks)
+- Suppression automatique des plus anciens
+- `supports_fifo() = true`
+
+**Structure :**
+
+```rust
+#[derive(Clone)]
+pub struct RadioParadiseSource {
+    base_url: String,
+    update_counter: Arc<RwLock<u32>>,
+    last_change: Arc<RwLock<SystemTime>>,
+    callback_tokens: Arc<std::sync::Mutex<Vec<u64>>>,
+    container_notifier: Option<Arc<dyn Fn(&[String]) + Send + Sync>>,
+}
+
+impl RadioParadiseSource {
+    // Enregistrer des callbacks sur les playlists pour notifier les changements
+    pub fn attach_playlist_callbacks(self: &Arc<Self>) {
+        let playlist_ids = vec![
+            self.live_playlist_id(),
+            self.history_playlist_id(),
+        ];
+
+        let manager = PlaylistManager();
+        let mut tokens = self.callback_tokens.lock().unwrap();
+
+        for pid in playlist_ids {
+            let weak = Arc::downgrade(self);
+            let pid_clone = pid.clone();
+            let token = manager.register_callback(move |event| {
+                if event.playlist_id == pid_clone {
+                    if let Some(strong) = weak.upgrade() {
+                        tokio::spawn(async move {
+                            strong.bump_update_counter().await;
+                            // Notifier ContentDirectory
+                            if let Some(notifier) = strong.container_notifier.as_ref() {
+                                notifier(&[format!("radio-paradise:history")]);
+                            }
+                        });
+                    }
+                }
+            });
+            tokens.push(token);
+        }
+    }
+}
+```
+
+**Points clés :**
+- Callbacks sur `pmoplaylist` pour détecter les changements
+- Notification du ContentDirectory via un notifier injecté
+- `update_counter` partagé via `Arc<RwLock<u32>>`
+
+### Pattern 2 : Source catalogue avec playlists lazy (Qobuz)
+
+**Caractéristiques :**
+- Catalogue vaste (millions de tracks)
+- Playlists créées à la demande
+- Cache lazy (cover eager, audio lazy)
+- `supports_fifo() = false`
+
+**Structure :**
+
+```rust
+#[derive(Clone)]
+pub struct QobuzSource {
+    inner: Arc<QobuzSourceInner>,
+}
+
+struct QobuzSourceInner {
+    client: Arc<QobuzClient>,
+    cache_manager: SourceCacheManager,
+    base_url: String,
+    update_counter: tokio::sync::RwLock<u32>,
+    last_change: tokio::sync::RwLock<SystemTime>,
+}
+
+impl QobuzSource {
+    // Ajouter un track avec cache lazy
+    pub async fn add_track_lazy(&self, track: &Track) -> Result<(String, String)> {
+        let track_id = format!("qobuz://track/{}", track.id);
+        let lazy_pk = format!("QOBUZ:{}", track.id);
+
+        // 1. Cache cover EAGERLY (petit, UI en a besoin)
+        let cached_cover_pk = if let Some(ref image_url) = track.album.as_ref()
+            .and_then(|a| a.image.as_ref()) {
+            self.inner.cache_manager.cache_cover(image_url).await.ok()
+        } else {
+            None
+        };
+
+        // 2. Préparer metadata
+        let metadata = AudioMetadata {
+            title: Some(track.title.clone()),
+            artist: track.performer.as_ref().map(|p| p.name.clone()),
+            album: track.album.as_ref().map(|a| a.title.clone()),
+            duration_secs: Some(track.duration as u64),
+            // ... autres champs
+        };
+
+        // 3. Cache audio LAZILY (grand, téléchargé à la demande)
+        let cached_audio_pk = self
+            .inner
+            .cache_manager
+            .cache_audio_lazy_with_provider(
+                &lazy_pk,
+                Some(metadata.clone()),
+                cached_cover_pk.clone(),
+            )
+            .await?;
+
+        // 4. Stocker metadata
+        self.inner.cache_manager.update_metadata(
+            track_id.clone(),
+            pmosource::TrackMetadata {
+                original_uri: stream_url,
+                cached_audio_pk: Some(cached_audio_pk.clone()),
+                cached_cover_pk,
+            },
+        ).await;
+
+        Ok((track_id, cached_audio_pk))
+    }
+
+    // Créer une playlist d'album avec TTL
+    async fn get_or_create_album_playlist_items(
+        &self,
+        album_id: &str,
+        limit: usize,
+    ) -> Result<Vec<Item>> {
+        const ALBUM_PLAYLIST_TTL: Duration = Duration::from_secs(7 * 24 * 3600);
+
+        let playlist_id = format!("qobuz-album-{}", album_id);
+        let playlist_manager = PlaylistManager();
+
+        // Vérifier validité (existe ET non expirée ET non vide)
+        let is_valid = self.is_album_playlist_valid(&playlist_id).await?;
+
+        if is_valid {
+            // Récupérer depuis playlist existante
+            let reader = playlist_manager.get_read_handle(&playlist_id).await?;
+            let items = reader.to_items(limit).await?;
+            return self.adapt_playlist_items_to_qobuz(items, album_id).await;
+        }
+
+        // Créer nouvelle playlist
+        let writer = playlist_manager
+            .create_persistent_playlist_with_role(
+                playlist_id.clone(),
+                pmoplaylist::PlaylistRole::Album,
+            )
+            .await?;
+
+        // Ajouter tracks avec cache lazy
+        self.add_album_to_playlist(&playlist_id, album_id).await?;
+
+        // Récupérer items
+        let reader = playlist_manager.get_read_handle(&playlist_id).await?;
+        let items = reader.to_items(limit).await?;
+        self.adapt_playlist_items_to_qobuz(items, album_id).await
+    }
+}
+```
+
+**Points clés :**
+- Cache lazy pour l'audio (téléchargé à la demande)
+- Cache eager pour les covers (petit, UI en a besoin)
+- Playlists avec TTL (7 jours)
+- `LazyProvider` pour télécharger l'audio lors de la lecture
+
+### Pattern 3 : Adaptation des IDs entre playlist et source
+
+Lorsqu'une source utilise `pmoplaylist`, les items retournés ont des IDs génériques. Il faut les adapter au schéma de la source :
+
+```rust
+async fn adapt_playlist_items_to_source(
+    &self,
+    items: Vec<Item>,
+    parent_id: &str,
+) -> Result<Vec<Item>> {
+    let mut adapted = Vec::with_capacity(items.len());
+
+    for mut item in items {
+        // Extraire cache_pk depuis l'URL du resource
+        let cache_pk = if let Some(resource) = item.resources.first() {
+            resource
+                .url
+                .strip_prefix("/audio/flac/")
+                .map(|s| s.to_string())
+        } else {
+            None

+                .cache_manager
+                .get_audio_metadata(&pk, "source_track_id")
+            {
+                if let Some(track_id) = track_id_value.as_str() {
+                    item.id = format!("my-source:track:{}", track_id);
+                }
+            }
+
+            // Convertir URL relative en absolue
+            if let Some(resource) = item.resources.first_mut() {
+                if resource.url.starts_with('/') {
+                    resource.url = format!("{}{}", self.base_url, resource.url);
+                }

+            }
+        } else {
+            item.album_art = Some(self.default_cover_url());
+        }
+
+        // Ajouter genre par défaut si absent (requis par certains clients)
+        if item.genre.is_none() {
+            item.genre = Some("Music".to_string());
+        }
+
+        adapted.push(item);
+    }
+
+    Ok(adapted)
+}
+```
+
+**Points clés :**
+- Stocker `source_track_id` dans les metadata du cache audio
+- Reconstituer l'ID correct lors de la récupération depuis playlist
+- Normaliser URLs (relatives → absolues)
+- Ajouter champs requis par certains clients UPnP
+
+## Intégration avec l'écosystème PMOMusic
+
+### Avec pmoplaylist
+
+Pour les sources dynamiques et les catalogues :
+
+```rust
+use pmoplaylist::{PlaylistManager, PlaylistRole};
+
+// Créer une playlist persistante
+let manager = PlaylistManager();
+let writer = manager
+    .create_persistent_playlist_with_role(
+        "my-source-album-123".to_string(),
+        PlaylistRole::Album,
+    )
+    .await?;
+
+// Configurer metadata
+writer.set_title("Album Title".to_string()).await?;
+writer.set_artist(Some("Artist Name".to_string())).await?;
+writer.set_cover_pk(Some("cover-pk".to_string())).await?;
+
+// Ajouter tracks avec cache lazy
+writer.push_lazy_batch(vec!["pk1", "pk2", "pk3"]).await?;
+
+// Activer mode lazy (lookahead 2 tracks)
+manager.enable_lazy_mode("my-source-album-123", 2);
+```
+
+### Avec pmoaudiocache et pmocovers (via SourceCacheManager)
+
+```rust
+use pmosource::SourceCacheManager;
+
+// Créer le manager centralisé
+let cache_manager = SourceCacheManager::from_registry("my-source".to_string())?;
+
+// Enregistrer un LazyProvider
+cache_manager.register_lazy_provider(Arc::new(MyLazyProvider::new(client)));
+
+// Cache eager (cover)
+let cover_pk = cache_manager.cache_cover("https://example.com/cover.jpg").await?;
+
+// Cache lazy (audio)
+let audio_pk = cache_manager
+    .cache_audio_lazy_with_provider(
+        "MY-SOURCE:123",  // Lazy PK
+        Some(metadata),
+        Some(cover_pk),
+    )
+    .await?;
+
+// Récupérer metadata
+let value = cache_manager.get_audio_metadata(&audio_pk, "key").await?;
+```
+
+**LazyProvider personnalisé :**
+
+```rust
+use pmoaudiocache::{LazyProvider, LazyProviderError};
+
+pub struct MyLazyProvider {
+    client: Arc<MyClient>,
+}
+
+#[async_trait]
+impl LazyProvider for MyLazyProvider {
+    async fn fetch_audio(&self, lazy_pk: &str) -> Result<Vec<u8>, LazyProviderError> {
+        // Extraire l'ID depuis le lazy_pk
+        let id = lazy_pk
+            .strip_prefix("MY-SOURCE:")
+            .ok_or_else(|| LazyProviderError::InvalidKey)?;
+
+        // Récupérer l'URL de streaming
+        let stream_url = self.client.get_stream_url(id).await
+            .map_err(|e| LazyProviderError::FetchFailed(e.to_string()))?;
+
+        // Télécharger l'audio
+        let response = reqwest::get(&stream_url).await
+            .map_err(|e| LazyProviderError::FetchFailed(e.to_string()))?;
+
+        let bytes = response.bytes().await
+            .map_err(|e| LazyProviderError::FetchFailed(e.to_string()))?;
+
+        Ok(bytes.to_vec())
+    }
+}
+```
+
+### Avec pmodidl
+
+Conversion de vos structures en DIDL-Lite :
+
+```rust
+use pmodidl::{Container, Item, Resource};
+
+// Container
+pub trait ToDIDLContainer {
+    fn to_didl_container(&self, parent_id: &str) -> Result<Container>;

+radio-paradise:channel:{slug}:history:track:{pk}  # Track dans historique
+```
+
+### Qobuz (source catalogue avec playlists lazy)

+
+**Points d'intérêt :**
+- `SourceCacheManager` centralisé
+- Cache lazy pour audio, eager pour covers
+- `LazyProvider` personnalisé
+- Playlists d'albums avec TTL (7 jours)
+- Adaptation IDs playlist → Qobuz
+- Navigation hiérarchique complexe (Discover, Genres, Favorites)
+
+**Schema d'Object ID :**
+```
+qobuz                                    # Racine
+qobuz:discover                           # Discover Catalog

+qobuz:genre:{id}                         # Genre spécifique
+qobuz:genre:{id}:new-releases            # Nouveautés du genre
+qobuz:favorites                          # My Music
+qobuz:favorites:albums                   # Albums favoris

+qobuz:track:{id}                         # Track spécifique
+qobuz:playlist:{id}                      # Playlist spécifique
+qobuz:artist:{id}                        # Artiste spécifique
+```
+
+## Conseils d'implémentation
+
+### Performance
+
+1. **Cache agressif** : Utilisez `SourceCacheManager` pour tout
+2. **Pagination** : Limitez le nombre d'items retournés (max 100)
+3. **Lazy loading** : Ne chargez que ce qui est demandé
+4. **Rate limiting** : Respectez les limites API de la source
+5. **Arc<>** : Partagez les données coûteuses
+
+### Compatibilité UPnP
+
+1. **Genre obligatoire** : Certains clients (gupnp-av-cp) requièrent `<upnp:genre>`
+2. **URLs absolues** : Toujours retourner des URLs complètes (pas de chemins relatifs)
+3. **Protocol Info** : Utilisez `http-get:*:audio/flac:*` pour FLAC
+4. **Duration** : Format `H:MM:SS` (ex: `0:03:45`)
+5. **childCount** : Optionnel mais recommandé pour l'UI
+
+### Gestion d'erreurs
+
+1. **ObjectNotFound** : ID invalide
+2. **BrowseError** : Erreur générique de navigation
+3. **UriResolutionError** : Impossible de résoudre l'URI
+4. **PlaylistError** : Erreur d'interaction avec pmoplaylist
+5. **CacheError** : Erreur de cache
+
+### Thread Safety
+
+1. **Arc<RwLock<>>** : Pour l'état mutable partagé
+2. **tokio::sync::RwLock** : Pour l'async
+3. **Éviter Rc<>** : Pas thread-safe
+4. **Clone** : Implémentez `Clone` pour `Arc<>`
+
+## Conclusion
+
+L'implémentation d'une nouvelle `MusicSource` suit ces étapes :
+
+1. **Définir le schéma d'Object ID** : Hiérarchie claire et cohérente
+2. **Implémenter la navigation** : `browse()` pour tous les niveaux
+3. **Résoudre les URIs** : Cache local d'abord, puis original
+4. **Gérer le cache** : `SourceCacheManager` + `LazyProvider`
+5. **Adapter les IDs** : Playlist → Schema de la source
+6. **Notifier les changements** : `update_id` + callbacks
+
+Les exemples Radio Paradise et Qobuz couvrent les deux patterns principaux :
+- **Dynamique FIFO** : Radio Paradise
+- **Catalogue lazy** : Qobuz
+
+En suivant ces patterns, vous obtiendrez une source musicale performante, compatible UPnP, et bien intégrée dans l'écosystème PMOMusic.

+# Pattern d'extension PMOServer (`pmoserver_ext`)
+
+## Vue d'ensemble
+
+Le pattern `pmoserver_ext` permet d'étendre les fonctionnalités du serveur HTTP `pmoserver` de manière modulaire et découplée. Chaque crate spécialisée peut ajouter ses propres routes HTTP sans que `pmoserver` ne dépende de ces crates.
+
+**Principe** : Définir un trait d'extension que `pmoserver::Server` implémente via une feature Cargo.
+
+## Anatomie d'une extension
+
+### 1. Structure du module
+
+Créer un module `pmoserver_ext.rs` dans la crate :
+
+```rust
+// pmoXXX/src/pmoserver_ext.rs
+
+#[cfg(feature = "pmoserver")]
+use crate::{/* types internes de la crate */};
+#[cfg(feature = "pmoserver")]
+use async_trait::async_trait;
+#[cfg(feature = "pmoserver")]
+use axum::{Router, routing::get, Json, extract::{State, Path}};
+#[cfg(feature = "pmoserver")]
+use std::sync::Arc;
+```
+
+Déclarer le module dans `lib.rs` :
+
+```rust
+// pmoXXX/src/lib.rs
+#[cfg(feature = "pmoserver")]
+pub mod pmoserver_ext;
+
+#[cfg(feature = "pmoserver")]
+pub use pmoserver_ext::XXXExt;
+```
+
+Ajouter la feature dans `Cargo.toml` :
+
+```toml
+[features]
+pmoserver = ["dep:axum", "dep:async-trait"]
+
+[dependencies]
+axum = { version = "0.8", optional = true }
+async-trait = { version = "0.1", optional = true }
+pmoserver = { path = "../pmoserver" }
+```
+
+### 2. Définir le trait d'extension
+
+**Convention de nommage** : `{Domaine}Ext` avec méthodes préfixées `init_*`
+
+```rust
+/// Trait pour étendre pmoserver avec les fonctionnalités XXX
+#[cfg(feature = "pmoserver")]
+#[async_trait]
+pub trait XXXExt {
+    /// Initialise l'extension XXX et enregistre les routes HTTP
+    ///
+    /// # Arguments
+    /// * `param1` - Description du paramètre
+    ///
+    /// # Returns
+    /// Instance partagée de la ressource créée
+    ///
+    /// # Exemple
+    /// ```ignore
+    /// use pmoserver::ServerBuilder;
+    /// use pmoXXX::XXXExt;
+    ///
+    /// let mut server = ServerBuilder::new(...).build();
+    /// let resource = server.init_xxx(param1).await?;
+    /// ```
+    async fn init_xxx(&mut self, param1: String) -> anyhow::Result<Arc<Resource>>;
+}
+```
+
+### 3. Implémenter le trait
+
+Implémenter le trait pour `pmoserver::Server` :
+
+```rust
+#[cfg(feature = "pmoserver")]
+#[async_trait]
+impl XXXExt for pmoserver::Server {
+    async fn init_xxx(&mut self, param1: String) -> anyhow::Result<Arc<Resource>> {
+        // 1. Créer la ressource interne
+        let resource = Arc::new(Resource::new(param1)?);
+        
+        // 2. Créer l'état partagé pour les handlers
+        let state = XxxState::new(resource.clone());
+        
+        // 3. Créer le router avec les routes
+        let router = create_xxx_router(state);
+        
+        // 4. Enregistrer le router sur le serveur
+        self.add_router("/api/xxx", router).await;
+        
+        // 5. Retourner la ressource pour usage ultérieur
+        Ok(resource)
+    }
+}
+```
+
+### 4. État partagé (State)
+
+Créer une structure d'état cloneable pour les handlers :
+
+```rust
+/// État partagé pour les handlers XXX
+#[derive(Clone)]
+pub struct XxxState {
+    resource: Arc<Resource>,
+}
+
+impl XxxState {
+    pub fn new(resource: Arc<Resource>) -> Self {
+        Self { resource }
+    }
+}
+```
+
+### 5. Créer le router
+
+Définir les routes et handlers :
+
+```rust
+/// Crée le router pour l'API XXX
+fn create_xxx_router(state: XxxState) -> Router {
+    Router::new()
+        .route("/items", get(list_items).post(create_item))
+        .route("/items/{id}", get(get_item).delete(delete_item))
+        .with_state(state)
+}
+
+// Handlers
+async fn list_items(
+    State(state): State<XxxState>
+) -> Json<Vec<ItemSummary>> {
+    let items = state.resource.list_items();
+    Json(items)
+}
+
+async fn get_item(
+    State(state): State<XxxState>,
+    Path(id): Path<String>,
+) -> Result<Json<Item>, StatusCode> {
+    state.resource.get_item(&id)
+        .ok_or(StatusCode::NOT_FOUND)
+        .map(Json)
+}
+```
+
+## Méthodes disponibles du serveur
+
+`pmoserver::Server` expose ces méthodes pour enregistrer des routes :
+
+| Méthode | Usage |
+|---------|-------|
+| `add_handler(path, handler)` | Ajoute un handler simple sans état |
+| `add_handler_with_state(path, handler, state)` | Ajoute un handler avec état partagé |
+| `add_router(path, router)` | Monte un sous-router Axum |
+| `add_openapi(router, doc, tag)` | Enregistre une API avec documentation OpenAPI |
+| `add_spa::<W>(path)` | Sert une Single Page Application (RustEmbed) |
+| `base_url()` | Récupère l'URL de base du serveur |
+
+## Documentation OpenAPI avec utoipa
+
+La documentation OpenAPI est essentielle pour une extension `pmoserver`. Elle génère automatiquement une interface Swagger UI et documente les endpoints de l'API.
+
+### Configuration de base
+
+Ajouter `utoipa` dans `Cargo.toml` :
+
+```toml
+[dependencies]
+utoipa = { version = "5", features = ["axum_extras"] }
+serde = { version = "1", features = ["derive"] }
+```
+
+### 1. Définir les schémas de données
+
+Annoter les structures de réponse/requête avec `#[derive(ToSchema)]` :
+
+```rust
+use serde::{Serialize, Deserialize};
+use utoipa::ToSchema;
+
+/// Information sur un item
+#[derive(Debug, Clone, Serialize, Deserialize, ToSchema)]
+pub struct ItemInfo {
+    /// ID unique de l'item
+    #[schema(example = "item-123")]
+    pub id: String,
+    
+    /// Nom de l'item
+    #[schema(example = "Mon Item")]
+    pub name: String,
+    
+    /// Description optionnelle
+    #[schema(example = "Une description détaillée")]
+    pub description: Option<String>,
+    
+    /// Timestamp de création (millisecondes)
+    #[schema(example = 1234567890)]
+    pub created_at: u64,
+}
+
+/// Liste d'items
+#[derive(Debug, Clone, Serialize, ToSchema)]
+pub struct ItemList {
+    /// Nombre total d'items
+    pub total: usize,
+    
+    /// Items de la page courante
+    pub items: Vec<ItemInfo>,
+}
+
+/// Requête de création d'item
+#[derive(Debug, Clone, Deserialize, ToSchema)]
+pub struct CreateItemRequest {
+    /// Nom de l'item à créer
+    #[schema(example = "Nouvel Item")]
+    pub name: String,
+    
+    /// Description optionnelle
+    pub description: Option<String>,
+}
+
+/// Réponse d'erreur standard
+#[derive(Debug, Clone, Serialize, ToSchema)]
+pub struct ErrorResponse {
+    /// Message d'erreur
+    #[schema(example = "Item not found")]
+    pub error: String,
+}
+```
+
+**Points clés** :
+- `#[schema(example = "...")]` : Fournit des exemples pour la doc Swagger
+- Documenter chaque champ avec `///` pour apparaître dans l'API
+- Utiliser `Option<T>` pour les champs optionnels
+
+### 2. Annoter les handlers
+
+Utiliser `#[utoipa::path(...)]` pour documenter chaque endpoint :
+

+
+**Structure de `#[utoipa::path]`** :
+- **Méthode HTTP** : `get`, `post`, `put`, `delete`, `patch`
+- **`path`** : Chemin de l'endpoint (doit correspondre au router)
+- **`params`** : Paramètres Path ou Query avec description
+- **`request_body`** : Type du body pour POST/PUT
+- **`responses`** : Liste des réponses possibles avec codes HTTP
+- **`tag`** : Groupe d'endpoints dans Swagger UI
+
+### 3. Créer la structure OpenAPI
+
+Définir une structure avec `#[derive(OpenApi)]` :
+
+```rust
+use utoipa::OpenApi;
+
+/// Documentation OpenAPI pour l'API XXX
+#[derive(OpenApi)]
+#[openapi(
+    info(
+        title = "XXX API",
+        version = "1.0.0",
+        description = r#"
+# API REST pour XXX
+
+Cette API permet de gérer les items XXX avec les fonctionnalités suivantes :
+
+## Fonctionnalités
+
+- **CRUD complet** : Création, lecture, mise à jour et suppression d'items
+- **Pagination** : Support de limit/offset pour les listes
+- **Filtrage** : Recherche par critères multiples
+- **Validation** : Vérification automatique des données
+
+## Exemples d'utilisation
+
+### Lister les items
+```
+GET /api/xxx/items?limit=10&offset=0
+```
+
+### Créer un item
+```
+POST /api/xxx/items
+Content-Type: application/json
+
+{
+  "name": "Mon Item",
+  "description": "Description détaillée"
+}
+```
+
+### Récupérer un item
+```
+GET /api/xxx/items/item-123
+```
+
+### Supprimer un item
+```
+DELETE /api/xxx/items/item-123
+```
+        "#
+    ),
+    paths(
+        list_items,
+        get_item,
+        create_item,
+        delete_item,
+    ),
+    components(schemas(
+        ItemInfo,
+        ItemList,
+        CreateItemRequest,
+        ErrorResponse,
+    )),
+    tags(
+        (name = "items", description = "Opérations sur les items")
+    )
+)]
+pub struct ApiDoc;
+```
+
+**Sections importantes** :
+- **`info`** : Titre, version et description Markdown de l'API
+- **`paths`** : Liste des fonctions handler annotées
+- **`components(schemas(...))`** : Liste des structures `ToSchema`
+- **`tags`** : Organisation des endpoints en groupes
+
+### 4. Enregistrer l'API avec OpenAPI
+
+Dans l'implémentation du trait d'extension :
+
+```rust
+#[async_trait]
+impl XxxExt for pmoserver::Server {
+    async fn init_xxx(&mut self) -> anyhow::Result<Arc<Resource>> {
+        let resource = Arc::new(Resource::new()?);
+        let state = XxxState { resource: resource.clone() };
+        
+        // Créer le router avec les routes
+        let router = Router::new()
+            .route("/items", get(list_items).post(create_item))
+            .route("/items/{id}", get(get_item).delete(delete_item))
+            .with_state(state);
+        
+        // Enregistrer avec OpenAPI (génère aussi /swagger-ui/xxx)
+        let openapi = ApiDoc::openapi();
+        self.add_openapi(router, openapi, "xxx").await;
+        
+        Ok(resource)
+    }
+}
+```
+
+**Ce que fait `add_openapi`** :
+- Monte le router sur `/api/{tag}/`
+- Génère la spec OpenAPI JSON sur `/api/{tag}/openapi.json`
+- Crée une UI Swagger sur `/swagger-ui/{tag}/`
+

+
+### Résultat : Interface Swagger
+
+Après avoir appelé `init_xxx()`, l'API est accessible :
+
+- **API JSON** : `http://localhost:8080/api/xxx/`
+- **Spec OpenAPI** : `http://localhost:8080/api/xxx/openapi.json`
+- **Swagger UI** : `http://localhost:8080/swagger-ui/xxx/`
+
+L'interface Swagger permet :
+- Parcourir tous les endpoints avec leur documentation
+- Tester les requêtes directement depuis le navigateur
+- Voir les schémas de données avec exemples
+- Consulter les codes de réponse HTTP possibles
+
+## Patterns courants
+
+### Pattern 1 : Extension simple avec router
+
+**Exemple** : `pmoparadise` (pmoparadise/src/pmoserver_ext.rs:367-392)
+
+```rust
+#[async_trait]
+impl RadioParadiseExt for pmoserver::Server {
+    async fn init_radioparadise(&mut self) -> anyhow::Result<State> {
+        let state = RadioParadiseState::new().await?;
+        
+        // Créer le router API
+        let api_router = create_api_router(state.clone());
+        
+        // Enregistrer avec OpenAPI
+        self.add_openapi(api_router, ApiDoc::openapi(), "radioparadise")
+            .await;
+        
+        Ok(state)
+    }
+}
+```
+
+### Pattern 2 : Extension avec cache et fichiers
+
+**Exemple** : `pmoaudiocache` (pmoaudiocache/src/lib.rs:225-260)
+
+```rust
+#[async_trait]
+impl AudioCacheExt for pmoserver::Server {
+    async fn init_audio_cache(
+        &mut self,
+        cache_dir: &str,
+        limit: usize,
+    ) -> anyhow::Result<Arc<Cache>> {
+        let cache = Arc::new(new_cache(cache_dir, limit)?);
+        
+        // Router pour servir les fichiers FLAC
+        let file_router = create_file_router(cache.clone(), "audio/flac");
+        self.add_router("/", file_router).await;
+        
+        // API REST
+        let api_router = Router::new()
+            .route("/", get(list).post(add))
+            .route("/{pk}", get(get_info).delete(delete))
+            .with_state(cache.clone());
+        
+        self.add_openapi(api_router, ApiDoc::openapi(), "audio").await;
+        
+        Ok(cache)
+    }
+}
+```
+
+### Pattern 3 : Extension avec routes dynamiques
+
+**Exemple** : `pmomediaserver` (pmomediaserver/src/paradise_streaming.rs:70-148)
+
+```rust
+#[async_trait]
+impl ParadiseStreamingExt for pmoserver::Server {
+    async fn init_paradise_streaming(&mut self) -> Result<Arc<Manager>> {
+        // 1. Récupérer/créer les ressources partagées
+        let audio_cache = get_or_init_audio_cache(self).await?;
+        let manager = Arc::new(Manager::new(audio_cache).await?);
+        
+        // 2. Créer l'état partagé
+        let state = Arc::new(StreamingState { manager: manager.clone() });
+        
+        // 3. Enregistrer les routes pour chaque canal
+        for descriptor in ALL_CHANNELS.iter() {
+            let slug = descriptor.slug;
+            
+            // Route streaming FLAC
+            let path = format!("/stream/{}/flac", slug);
+            self.add_handler_with_state(
+                &path,
+                move |State(s): State<Arc<StreamingState>>| async move {
+                    stream_flac(s.manager.clone(), descriptor.id).await
+                },
+                state.clone(),
+            ).await;
+            
+            // Route streaming OGG
+            let path = format!("/stream/{}/ogg", slug);
+            self.add_handler_with_state(
+                &path,
+                move |State(s): State<Arc<StreamingState>>| async move {
+                    stream_ogg(s.manager.clone(), descriptor.id).await
+                },
+                state.clone(),
+            ).await;
+        }
+        
+        Ok(manager)
+    }
+}
+```
+
+## Gestion des opérations longues
+
+### Utiliser `spawn_blocking` pour le code synchrone
+
+Pour éviter de bloquer le runtime Tokio avec du code synchrone :
+
+```rust
+async fn list_renderers(
+    State(state): State<ControlPointState>
+) -> Json<Vec<Summary>> {
+    let control_point = state.control_point.clone();
+    
+    let summaries = tokio::task::spawn_blocking(move || {
+        let renderers = control_point.list_music_renderers();
+        renderers.into_iter()
+            .map(|r| Summary::from(&r))
+            .collect()
+    })
+    .await
+    .unwrap_or_default();
+    
+    Json(summaries)
+}
+```
+
+### Ajouter des timeouts pour les opérations réseau
+
+```rust
+const COMMAND_TIMEOUT: Duration = Duration::from_secs(5);
+
+async fn play_renderer(
+    State(state): State<ControlPointState>,
+    Path(id): Path<String>,
+) -> Result<Json<Response>, (StatusCode, Json<Error>)> {
+    let renderer = state.get_renderer(&id)
+        .ok_or((StatusCode::NOT_FOUND, Json(Error::not_found())))?;
+    
+    let play_task = tokio::task::spawn_blocking(move || renderer.play());
+    
+    time::timeout(COMMAND_TIMEOUT, play_task)
+        .await
+        .map_err(|_| (
+            StatusCode::GATEWAY_TIMEOUT,
+            Json(Error::timeout())
+        ))?
+        .map_err(|e| (
+            StatusCode::INTERNAL_SERVER_ERROR,
+            Json(Error::internal(e))
+        ))??;
+    
+    Ok(Json(Response::success()))
+}
+```
+
+### Utiliser `spawn` pour les tâches en arrière-plan
+
+Pour les opérations qui ne nécessitent pas d'attendre le résultat :
+
+```rust
+async fn trigger_action(
+    State(state): State<XxxState>,
+    Json(req): Json<Request>,
+) -> Json<Response> {
+    // Valider la requête
+    state.validate(&req)?;
+    
+    // Lancer l'action en arrière-plan
+    let state_clone = state.clone();
+    tokio::task::spawn(async move {
+        match state_clone.perform_action(req).await {
+            Ok(_) => debug!("Action completed"),
+            Err(e) => warn!("Action failed: {}", e),
+        }
+    });
+    
+    // Retourner immédiatement
+    Json(Response::accepted())
+}
+```

+# Rapport Final : Items Épinglables et TTL dans PMOcache
+
+## Objectif de la tâche
+
+Étendre le système de cache PMOcache pour permettre un contrôle plus fin des règles de suppression des items. L'objectif était double :
+
+1. **Phase 1** : Implémenter un système d'items épinglables (pinned) protégés de l'éviction LRU, avec support du TTL (Time To Live) pour l'expiration automatique
+2. **Phase 2** : Exposer ces fonctionnalités via une API REST complète avec documentation OpenAPI
+
+## Contexte
+
+La crate PMOcache implémente un système de cache avec :
+- Capacité maximale configurable
+- Politique d'éviction LRU (Least Recently Used)
+- TTL optionnel pour les items
+
+La nouvelle fonctionnalité permet de :
+- **Épingler** des items critiques pour les rendre permanents
+- **Exclure** les items épinglés du comptage de la limite du cache
+- **Définir un TTL** pour supprimer automatiquement les items temporaires
+- **Garantir l'incompatibilité** entre pinning et TTL (règle métier)
+
+## Architecture de la solution
+
+### 1. Modifications de la base de données
+
+#### Schéma SQL étendu
+
+```sql
+CREATE TABLE IF NOT EXISTS asset (
+    pk TEXT PRIMARY KEY,
+    collection TEXT,
+    id TEXT,
+    hits INTEGER DEFAULT 0,
+    last_used TEXT,
+    lazy_pk TEXT,
+    pinned INTEGER DEFAULT 0 CHECK (pinned IN (0, 1)),
+    ttl_expires_at TEXT
+)
+```
+
+Deux nouvelles colonnes :
+- **`pinned`** : Booléen (0/1) indiquant si l'item est protégé
+- **`ttl_expires_at`** : Date RFC3339 d'expiration (optionnel)
+
+#### Structure `CacheEntry` enrichie
+
+```rust
+pub struct CacheEntry {
+    pub pk: String,
+    pub lazy_pk: Option<String>,
+    pub id: Option<String>,
+    pub collection: Option<String>,
+    pub hits: i32,
+    pub last_used: Option<String>,
+    pub pinned: bool,                    // Nouveau
+    pub ttl_expires_at: Option<String>,  // Nouveau
+    pub metadata: Option<Value>,
+}
+```
+
+### 2. API de base de données (db.rs)
+
+#### Nouvelles méthodes implémentées
+
+##### Gestion du comptage
+- **`count_unpinned()`** : Compte uniquement les items non épinglés
+  - Les items épinglés sont exclus de la limite du cache
+
+##### Gestion du pinning
+- **`pin(pk)`** : Épingle un item
+  - Vérifie qu'aucun TTL n'est défini (règle métier)
+  - Retourne erreur si TTL présent
+  
+- **`unpin(pk)`** : Désépingle un item
+
+- **`is_pinned(pk)`** : Vérifie le statut de pinning
+
+##### Gestion du TTL
+- **`set_ttl(pk, expires_at)`** : Définit la date d'expiration
+  - Vérifie que l'item n'est pas épinglé (règle métier)
+  - Retourne erreur si épinglé
+  
+- **`clear_ttl(pk)`** : Supprime le TTL
+
+- **`get_expired()`** : Récupère tous les items expirés
+
+##### Modification de `get_oldest()`
+
+Exclusion automatique des items épinglés :
+
+```sql
+SELECT ... FROM asset
+WHERE pinned = 0
+ORDER BY last_used ASC, hits ASC
+LIMIT ?1
+```
+
+### 3. Logique du cache (cache.rs)
+
+#### Méthodes publiques exposées
+
+```rust
+pub async fn pin(&self, pk: &str) -> Result<()>
+pub async fn unpin(&self, pk: &str) -> Result<()>
+pub async fn is_pinned(&self, pk: &str) -> Result<bool>
+pub async fn set_ttl(&self, pk: &str, expires_at: &str) -> Result<()>
+pub async fn clear_ttl(&self, pk: &str) -> Result<()>
+```
+
+#### Politique d'éviction améliorée
+
+La méthode `enforce_limit()` a été complètement repensée :
+
+```rust
+pub async fn enforce_limit(&self) -> Result<usize> {
+    // 1. Supprimer d'abord les items expirés (TTL dépassé)
+    let expired_entries = self.db.get_expired()?;
+    for entry in expired_entries {
+        // Suppression fichiers + DB
+    }
+
+    // 2. Compter UNIQUEMENT les items non épinglés
+    let count = self.db.count_unpinned()?;
+
+    // 3. Si limite dépassée, supprimer les plus vieux (non épinglés)
+    if count > self.limit {
+        let to_remove = count - self.limit;
+        let old_entries = self.db.get_oldest(to_remove)?;
+        // Suppression...
+    }
+}
+```
+
+**Ordre de priorité** :
+1. Items expirés (TTL) → suppression immédiate
+2. Items non épinglés les plus vieux (LRU) → suppression si limite dépassée
+3. Items épinglés → **jamais supprimés automatiquement**
+
+### 4. API REST (api.rs)
+
+#### Nouvelles structures de données
+
+```rust
+#[derive(Serialize, Deserialize, ToSchema)]
+pub struct PinStatus {
+    pub pk: String,
+    pub pinned: bool,
+    pub ttl_expires_at: Option<String>,
+}
+
+#[derive(Serialize, Deserialize, ToSchema)]
+pub struct PinResponse {
+    pub pk: String,
+    pub message: String,
+}
+
+#[derive(Serialize, Deserialize, ToSchema)]
+pub struct SetTtlRequest {
+    pub expires_at: String,  // RFC3339
+}
+```
+
+#### Handlers HTTP implémentés
+
+##### `get_pin_status(pk)` - GET /{pk}/pin
+Récupère le statut actuel de pinning et TTL d'un item.
+
+**Réponse 200 OK** :
+```json
+{
+  "pk": "1a2b3c4d5e6f7a8b",
+  "pinned": false,
+  "ttl_expires_at": null
+}
+```
+
+##### `pin_item(pk)` - POST /{pk}/pin
+Épingle un item pour le protéger de l'éviction.
+
+**Réponse 200 OK** :
+```json
+{
+  "pk": "1a2b3c4d5e6f7a8b",
+  "message": "Item '1a2b3c4d5e6f7a8b' pinned successfully"
+}
+```
+
+**Réponse 409 CONFLICT** (si TTL défini) :
+```json
+{
+  "error": "CONFLICT",
+  "message": "Cannot pin an item with TTL set. Clear TTL first."
+}
+```
+
+##### `unpin_item(pk)` - DELETE /{pk}/pin
+Désépingle un item.
+
+##### `set_item_ttl(pk, request)` - POST /{pk}/ttl
+Définit le TTL d'un item.
+
+**Requête** :
+```json
+{
+  "expires_at": "2025-01-20T10:30:00Z"
+}
+```
+
+**Réponse 409 CONFLICT** (si épinglé) :
+```json
+{
+  "error": "CONFLICT",
+  "message": "Cannot set TTL on a pinned item. Unpin first."
+}
+```
+
+**Réponse 400 BAD REQUEST** (format invalide) :
+```json
+{
+  "error": "INVALID_DATE",
+  "message": "Invalid RFC3339 date format"
+}
+```
+
+##### `clear_item_ttl(pk)` - DELETE /{pk}/ttl
+Supprime le TTL d'un item.
+
+### 5. Routes HTTP (pmoserver_ext.rs)
+
+Routes ajoutées au router API :
+
+```rust
+Router::new()
+    // ... routes existantes ...
+    .route(
+        "/{pk}/pin",
+        get(api::get_pin_status::<C>)
+            .post(api::pin_item::<C>)
+            .delete(api::unpin_item::<C>),
+    )
+    .route(
+        "/{pk}/ttl",
+        post(api::set_item_ttl::<C>)
+            .delete(api::clear_item_ttl::<C>),
+    )
+```
+
+**URLs complètes** (exemple pour cache audio) :
+- `GET /api/audio/{pk}/pin`
+- `POST /api/audio/{pk}/pin`
+- `DELETE /api/audio/{pk}/pin`
+- `POST /api/audio/{pk}/ttl`
+- `DELETE /api/audio/{pk}/ttl`
+
+### 6. Documentation OpenAPI (openapi.rs)
+
+La macro `create_cache_openapi!` a été enrichie pour inclure automatiquement :
+
+```rust
+#[openapi(
+    paths(
+        // ... paths existants ...
+        $crate::api::get_pin_status::<Self>,
+        $crate::api::pin_item::<Self>,
+        $crate::api::unpin_item::<Self>,
+        $crate::api::set_item_ttl::<Self>,
+        $crate::api::clear_item_ttl::<Self>,
+    ),
+    components(
+        schemas(
+            // ... schemas existants ...
+            $crate::api::PinStatus,
+            $crate::api::PinResponse,
+            $crate::api::SetTtlRequest,
+        )
+    ),
+)]
+```
+
+**Accès Swagger UI** : `/swagger-ui/{cache_name}`
+
+## Règles métier implémentées
+
+### 1. Incompatibilité stricte : Pinned ↔ TTL
+
+Un item ne peut **jamais** être à la fois épinglé ET avoir un TTL :
+
+| État actuel | Action | Résultat |
+|-------------|--------|----------|
+| Aucun TTL | `pin()` | ✅ Succès |
+| TTL défini | `pin()` | ❌ Erreur 409 |
+| Non épinglé | `set_ttl()` | ✅ Succès |
+| Épinglé | `set_ttl()` | ❌ Erreur 409 |
+
+**Rationale** :
+- **Épinglé** = permanent, ne doit jamais être supprimé automatiquement
+- **TTL** = temporaire, sera supprimé à expiration
+- Ces deux concepts sont sémantiquement contradictoires
+
+### 2. Exclusion du comptage
+
+Les items épinglés ne comptent **pas** dans la limite du cache :
+
+```rust
+// Cache avec limite de 100 items
+let unpinned_count = cache.db.count_unpinned()?;  // 100
+let total_count = cache.db.count()?;              // 150
+
+// Le cache peut contenir :
+// - 100 items non épinglés (limite respectée)
+// - 50 items épinglés (hors limite)
+```
+
+### 3. Protection absolue contre l'éviction
+
+Les items épinglés sont **jamais** retournés par `get_oldest()` :
+
+```sql
+-- Requête LRU exclut automatiquement les épinglés
+SELECT ... FROM asset
+WHERE pinned = 0  -- ← Filtre explicite
+ORDER BY last_used ASC
+```
+
+## Tests et validation
+
+### Suite de tests dédiée (test_pinnable.rs)
+
+9 tests couvrant tous les cas d'usage :
+
+1. **`test_pin_unpin`** : Épinglage/désépinglage basique
+2. **`test_pinned_excluded_from_lru`** : Items épinglés protégés de l'éviction
+3. **`test_pinned_count_separately`** : Comptage séparé des items
+4. **`test_cannot_pin_with_ttl`** : Règle métier TTL → pas de pin
+5. **`test_cannot_set_ttl_when_pinned`** : Règle métier pin → pas de TTL
+6. **`test_ttl_expiration`** : Suppression automatique des items expirés
+7. **`test_clear_ttl`** : Suppression du TTL
+8. **`test_get_expired`** : Récupération des items expirés
+9. **`test_cache_entry_fields`** : Vérification des champs dans les entrées
+
+**Résultat** : ✅ 9/9 tests passent
+
+### Tests de non-régression
+
+Tous les tests existants de `test_cache.rs` passent sans modification :
+- Test de création de cache
+- Test d'ajout de fichiers
+- Test de déduplication
+- Test de collections
+- Test de suppression
+- Test d'éviction LRU
+- Test de purge
+- Test de consolidation
+
+**Résultat** : ✅ Aucune régression détectée
+
+### Compilation
+
+```bash
+cargo build -p pmocache
+```
+
+**Résultat** : ✅ Compilation sans erreur ni warning
+
+## Compatibilité et migration
+
+### Rétrocompatibilité de la base de données
+
+**Aucune migration manuelle requise**. Les colonnes ont des valeurs par défaut :
+
+```sql
+pinned INTEGER DEFAULT 0         -- Non épinglé par défaut
+ttl_expires_at TEXT              -- NULL par défaut
+```
+
+Les bases existantes sont automatiquement compatibles :
+- Tous les items existants sont non épinglés
+- Aucun TTL défini par défaut
+- Le comportement LRU standard reste identique
+
+### Rétrocompatibilité du code
+
+Toutes les méthodes existantes continuent de fonctionner :
+- `add_from_url()`, `add_from_file()`, `get()`, etc.
+- Pas de changement de signature
+- Comportement LRU identique pour les items non épinglés

+
+## Exemples d'utilisation
+
+### Utilisation programmatique (Rust)
+
+```rust
+use pmocache::{Cache, CacheConfig};
+use chrono::{Duration, Utc};
+
+// Créer un cache
+let cache = Cache::<MyConfig>::new("./cache", 100)?;
+
+// Ajouter un fichier
+let pk = cache.add_from_url("https://example.com/file.dat", None).await?;
+
+// ═══════════════════════════════════════
+// Scénario 1 : Item permanent (épinglé)
+// ═══════════════════════════════════════
+cache.pin(&pk).await?;
+
+// Vérifier le statut
+assert!(cache.is_pinned(&pk).await?);
+
+// L'item ne sera JAMAIS supprimé automatiquement
+// même si le cache est plein
+
+// ═══════════════════════════════════════
+// Scénario 2 : Item temporaire (TTL)
+// ═══════════════════════════════════════
+let pk2 = cache.add_from_url("https://example.com/temp.dat", None).await?;
+
+// Définir une expiration dans 24h
+let expires_at = (Utc::now() + Duration::hours(24)).to_rfc3339();
+cache.set_ttl(&pk2, &expires_at).await?;
+
+// L'item sera automatiquement supprimé après 24h
+// lors du prochain appel à enforce_limit()
+
+// ═══════════════════════════════════════
+// Scénario 3 : Conversion épinglé → TTL
+// ═══════════════════════════════════════
+cache.unpin(&pk).await?;  // Désépingler d'abord
+cache.set_ttl(&pk, &expires_at).await?;  // OK maintenant
+```
+
+### Utilisation via API REST
+
+#### Workflow complet : Épingler un fichier important
+
+```bash
+# 1. Ajouter un fichier au cache
+curl -X POST http://localhost:8080/api/audio/ \
+  -H "Content-Type: application/json" \
+  -d '{"url": "https://example.com/important.flac"}'
+
+# Réponse :
+# {
+#   "pk": "abc123def456",
+#   "url": "https://example.com/important.flac",
+#   "message": "Item added successfully"
+# }
+
+# 2. Vérifier le statut actuel
+curl http://localhost:8080/api/audio/abc123def456/pin
+
+# Réponse :
+# {
+#   "pk": "abc123def456",
+#   "pinned": false,
+#   "ttl_expires_at": null
+# }
+
+# 3. Épingler le fichier
+curl -X POST http://localhost:8080/api/audio/abc123def456/pin
+
+# Réponse :
+# {
+#   "pk": "abc123def456",
+#   "message": "Item 'abc123def456' pinned successfully"
+# }
+
+# 4. Vérifier qu'il est épinglé
+curl http://localhost:8080/api/audio/abc123def456/pin
+
+# Réponse :
+# {
+#   "pk": "abc123def456",
+#   "pinned": true,
+#   "ttl_expires_at": null
+# }
+```
+
+#### Workflow : Fichier temporaire avec TTL
+
+```bash
+# 1. Ajouter un fichier
+curl -X POST http://localhost:8080/api/audio/ \
+  -H "Content-Type: application/json" \
+  -d '{"url": "https://example.com/preview.flac"}'
+
+# Réponse : {"pk": "xyz789abc123", ...}
+
+# 2. Définir un TTL de 1 heure
+curl -X POST http://localhost:8080/api/audio/xyz789abc123/ttl \
+  -H "Content-Type: application/json" \
+  -d '{"expires_at": "2025-01-15T11:30:00Z"}'
+
+# Réponse :
+# {
+#   "pk": "xyz789abc123",
+#   "message": "TTL set successfully for item 'xyz789abc123'"
+# }
+
+# 3. Le fichier sera automatiquement supprimé après expiration
+```
+
+#### Gestion d'erreur : Conflit de règle métier
+
+```bash
+# 1. Épingler un item
+curl -X POST http://localhost:8080/api/audio/abc123/pin
+# OK
+
+# 2. Essayer de définir un TTL (interdit)
+curl -X POST http://localhost:8080/api/audio/abc123/ttl \
+  -H "Content-Type: application/json" \
+  -d '{"expires_at": "2025-01-15T12:00:00Z"}'
+
+# Réponse 409 CONFLICT :
+# {
+#   "error": "CONFLICT",
+#   "message": "Cannot set TTL on a pinned item. Unpin first."
+# }
+
+# 3. Solution : désépingler puis définir TTL
+curl -X DELETE http://localhost:8080/api/audio/abc123/pin
+curl -X POST http://localhost:8080/api/audio/abc123/ttl \
+  -H "Content-Type: application/json" \
+  -d '{"expires_at": "2025-01-15T12:00:00Z"}'
+# OK
+```

+## Avantages de la solution
+
+### 1. Architecture propre et extensible
+
+- **Séparation des responsabilités** :
+  - `db.rs` : logique de base de données
+  - `cache.rs` : logique métier
+  - `api.rs` : interface HTTP
+  
+- **Réutilisabilité** :
+  - Traits existants conservés
+  - Pas de duplication de code
+  - Pattern cohérent avec l'architecture PMOcache
+
+### 2. Sécurité et fiabilité
+
+- **Règles métier strictes** :
+  - Incompatibilité TTL ↔ Pinned appliquée à tous les niveaux
+  - Validation au niveau DB, cache ET API
+  
+- **Gestion d'erreurs robuste** :
+  - Codes HTTP sémantiques
+  - Messages explicites
+  - Pas d'état incohérent possible
+
+### 3. Performance
+
+- **Requêtes SQL optimisées** :
+  - Index sur `pinned` pour requêtes rapides
+  - `WHERE pinned = 0` évite le scan complet
+  
+- **Comptage efficace** :
+  - `count_unpinned()` utilise un index
+  - Pas de post-filtrage en mémoire
+
+### 4. Expérience développeur
+
+- **API intuitive** :
+  - Méthodes async cohérentes avec l'existant
+  - Nommage clair (`pin()`, `unpin()`, `set_ttl()`)
+  
+- **Documentation complète** :
+  - OpenAPI générée automatiquement
+  - Swagger UI interactive
+  - Exemples d'utilisation
+
+### 5. Compatibilité
+
+- **Migration transparente** :
+  - Aucune intervention manuelle
+  - Valeurs par défaut appropriées
+  
+- **Pas de breaking change** :
+  - API existante inchangée
+  - Nouveaux champs optionnels dans `CacheEntry`
+
+## Cas d'usage concrets
+
+### 1. Cache de couvertures d'albums
+
+```rust
+// Épingler les couvertures des albums favoris
+for album in user.favorite_albums {
+    let cover_pk = covers_cache.get_cover_pk(&album.id).await?;
+    covers_cache.pin(&cover_pk).await?;
+}
+
+// → Les couvertures favorites restent toujours en cache
+// → Même si le cache se remplit de nouvelles couvertures
+```
+
+### 2. Cache audio avec previews temporaires
+
+```rust
+// Pistes complètes : épinglées si dans la playlist courante
+for track in current_playlist.tracks {
+    audio_cache.pin(&track.pk).await?;
+}
+
+// Previews de 30 secondes : TTL de 1 heure
+let preview_pk = audio_cache.add_preview(&track_url).await?;
+let expires_at = (Utc::now() + Duration::hours(1)).to_rfc3339();
+audio_cache.set_ttl(&preview_pk, &expires_at).await?;
+
+// → Pistes courantes toujours disponibles
+// → Previews nettoyées automatiquement
+```
+
+### 3. Cache de métadonnées avec rafraîchissement
+
+```rust
+// Métadonnées d'album : TTL de 24h pour forcer le rafraîchissement
+let metadata_pk = metadata_cache.add_metadata(&album).await?;
+let tomorrow = (Utc::now() + Duration::days(1)).to_rfc3339();
+metadata_cache.set_ttl(&metadata_pk, &tomorrow).await?;
+
+// → Métadonnées rafraîchies quotidiennement
+// → Pas de données obsolètes
+```
+
+## Limitations et considérations
+
+### 1. Pas de limite sur les items épinglés
+
+Les items épinglés peuvent s'accumuler indéfiniment. Recommandations :
+
+```rust
+// Surveiller le nombre d'items épinglés
+let pinned_count = cache.db.count()? - cache.db.count_unpinned()?;
+if pinned_count > MAX_PINNED_ITEMS {
+    warn!("Too many pinned items: {}", pinned_count);
+}
+```
+
+### 2. TTL vérifié uniquement lors de `enforce_limit()`
+
+Les items expirés ne sont pas supprimés immédiatement. Solutions possibles :
+
+```rust
+// Option 1 : Appel périodique
+tokio::spawn(async move {
+    loop {
+        tokio::time::sleep(Duration::from_secs(3600)).await;
+        cache.enforce_limit().await?;
+    }
+});
+
+// Option 2 : Vérification à l'accès
+if let Ok(entry) = cache.db.get(&pk, false) {
+    if let Some(ttl) = entry.ttl_expires_at {
+        if Utc::now() > DateTime::parse_from_rfc3339(&ttl)? {
+            cache.delete_item(&pk).await?;
+        }
+    }
+}
+```
+
+### 3. Format de date RFC3339 strict
+
+L'API exige le format RFC3339. Exemples valides :
+
+```
+2025-01-15T10:30:00Z           ✅ UTC
+2025-01-15T10:30:00+01:00      ✅ Avec timezone
+2025-01-15T10:30:00.123Z       ✅ Avec millisecondes
+2025-01-15 10:30:00            ❌ Format invalide
+```
+
+## Évolutions futures possibles
+
+### 1. Gestion automatique du TTL
+
+Implémenter un worker en arrière-plan :
+
+```rust
+pub async fn start_ttl_worker(&self) {
+    tokio::spawn(async move {
+        loop {
+            self.enforce_limit().await;
+            tokio::time::sleep(Duration::from_secs(60)).await;
+        }
+    });
+}
+```
+
+### 2. Pinning conditionnel
+
+Épingler automatiquement selon des critères :
+
+```rust
+pub async fn pin_if<F>(&self, predicate: F) -> Result<Vec<String>>
+where
+    F: Fn(&CacheEntry) -> bool,
+{
+    let entries = self.db.get_all(false)?;
+    let mut pinned = Vec::new();
+    
+    for entry in entries {
+        if predicate(&entry) && !entry.pinned {
+            self.pin(&entry.pk).await?;
+            pinned.push(entry.pk);
+        }
+    }
+    
+    Ok(pinned)
+}
+
+// Utilisation
+cache.pin_if(|e| e.hits > 100).await?;  // Épingler les plus utilisés
+```
+
+### 3. TTL relatif
+
+Faciliter la définition de TTL :
+
+```rust
+pub async fn set_ttl_relative(&self, pk: &str, duration: Duration) -> Result<()> {
+    let expires_at = (Utc::now() + duration).to_rfc3339();
+    self.set_ttl(pk, &expires_at).await
+}
+
+// Utilisation
+cache.set_ttl_relative(&pk, Duration::hours(24)).await?;
+```
+
+### 4. Statistiques de pinning
+
+```rust
+pub async fn get_pinning_stats(&self) -> Result<PinningStats> {
+    Ok(PinningStats {
+        total_items: self.db.count()?,
+        pinned_items: self.db.count()? - self.db.count_unpinned()?,
+        items_with_ttl: self.db.count_with_ttl()?,
+        expired_items: self.db.get_expired()?.len(),
+    })
+}
+```

+# Rapport : Suppression de la logique de débouncing SSE
+
+**Date**: 2026-01-12
+**Tâche**: WeabApp_debouncingSSE.md
+
+## Objectif
+
+Supprimer la logique de débouncing inutile sur le canal SSE de l'application web PMOControl, puisque le serveur contrôle déjà le flux des événements.
+
+## Analyse préalable
+
+J'ai identifié trois endroits avec des mécanismes de temporisation dans l'application web :
+
+### 1. MediaBrowser.vue - Débouncing SSE (À SUPPRIMER ✓)
+- **Débouncing**: 200ms après invalidation du cache
+- **Cooldown**: 2 secondes entre les rechargements
+- **Justification originale**: "dédupliquer les événements SSE dans le même batch (polling 500ms)"
+- **Problème**: Cette logique est redondante puisque le serveur contrôle déjà le flux SSE
+
+### 2. useRenderers.ts - Smart fetching (À CONSERVER ✓)
+- **Mécanisme**: Comparaison des timestamps `lastEventAt` vs `lastSnapshotAt`
+- **But**: Éviter de refetch un snapshot déjà à jour
+- **Justification**: Ce n'est PAS du débouncing, c'est une optimisation intelligente qui évite des appels API inutiles
+
+### 3. VolumeControl.vue - UI debouncing (À CONSERVER ✓)
+- **Débouncing**: 300ms sur les changements de volume
+- **But**: Réduire les appels API pendant que l'utilisateur fait glisser le curseur
+- **Justification**: Débouncing légitime pour l'interface utilisateur
+
+## Modifications effectuées
+
+### Fichier modifié: `pmoapp/webapp/src/components/pmocontrol/MediaBrowser.vue`
+
+#### 1. Suppression des variables de débouncing (ligne ~27)
+
+**Avant**:
+```typescript
+// Flags pour gérer le rechargement automatique avec debounce et cooldown
+const isRefreshing = ref(false);
+const refreshTimeoutId = ref<number | null>(null);
+const lastRefreshTime = ref<number>(0);
+const REFRESH_COOLDOWN_MS = 2000; // Ne pas recharger plus d'une fois toutes les 2 secondes
+```
+
+**Après**:
+```typescript
+// Flag pour gérer le rechargement automatique
+const isRefreshing = ref(false);
+```
+
+#### 2. Simplification du watcher de cache (ligne ~53)
+
+**Avant**:
+```typescript
+// Recharger automatiquement si le cache est invalidé (ex: après un ContainersUpdated SSE)
+// Cela se produit notamment quand on clique sur "Lire maintenant" sur une playlist,
+// ce qui déclenche un événement ContainersUpdated qui invalide le cache
+// Utilise un debounce de 3 secondes pour regrouper les multiples invalidations
+// et un cooldown de 5 secondes pour éviter les rechargements successifs
+watch(
+    () => browseData.value,
+    (data) => {
+        if (!data && props.containerId && !loading.value) {
+            // Vérifier le cooldown: ignorer si on a rechargé il y a moins de 5 secondes
+            const timeSinceLastRefresh = Date.now() - lastRefreshTime.value;
+            if (timeSinceLastRefresh < REFRESH_COOLDOWN_MS) {
+                console.log(
+                    `[MediaBrowser] Cache invalidé mais cooldown actif (${Math.round((REFRESH_COOLDOWN_MS - timeSinceLastRefresh) / 1000)}s restantes), rechargement ignoré`,
+                );
+                return;
+            }
+
+            // Annuler tout timeout en cours
+            if (refreshTimeoutId.value !== null) {
+                clearTimeout(refreshTimeoutId.value);
+            }
+
+            // Planifier le rechargement après 200ms
+            refreshTimeoutId.value = window.setTimeout(async () => {
+                if (!isRefreshing.value) {
+                    console.log(
+                        `[MediaBrowser] Cache invalidé pour ${props.serverId}/${props.containerId}, rechargement après debounce...`,
+                    );
+                    isRefreshing.value = true;
+                    await browseContainer(
+                        props.serverId,
+                        props.containerId,
+                        false,
+                    );
+                    lastRefreshTime.value = Date.now();
+                    isRefreshing.value = false;
+                    refreshTimeoutId.value = null;
+                }
+            }, 200);
+        }
+    },
+);
+```
+
+**Après**:
+```typescript
+// Recharger automatiquement si le cache est invalidé (ex: après un ContainersUpdated SSE)
+// Cela se produit notamment quand on clique sur "Lire maintenant" sur une playlist,
+// ce qui déclenche un événement ContainersUpdated qui invalide le cache
+// Le serveur contrôle déjà le flux SSE, pas besoin de debouncing côté client
+watch(
+    () => browseData.value,
+    async (data) => {
+        // Si browseData devient undefined alors que containerId est présent,
+        // et qu'on n'est pas déjà en train de charger, recharger immédiatement
+        if (!data && props.containerId && !loading.value && !isRefreshing.value) {
+            console.log(
+                `[MediaBrowser] Cache invalidé pour ${props.serverId}/${props.containerId}, rechargement...`,
+            );
+            isRefreshing.value = true;
+            await browseContainer(props.serverId, props.containerId, false);
+            isRefreshing.value = false;
+        }
+    },
+);
+```
+
+## Résultats
+
+### Changements de comportement
+- **Avant**: Délai de 200ms + cooldown de 2s entre les rechargements de cache
+- **Après**: Rechargement immédiat dès l'invalidation du cache
+- **Impact**: Réactivité améliorée de l'interface, les mises à jour apparaissent immédiatement
+
+### Réduction de complexité
+- **3 variables supprimées**: `refreshTimeoutId`, `lastRefreshTime`, `REFRESH_COOLDOWN_MS`
+- **Logique simplifiée**: De ~40 lignes à ~10 lignes dans le watcher
+- **Code plus lisible**: Intention claire sans mécanismes de temporisation complexes
+
+### Tests
+- ✓ Le projet compile sans erreurs TypeScript
+- ✓ Le flag `isRefreshing` empêche toujours les rechargements concurrents
+- ✓ Les autres composants (useRenderers.ts, VolumeControl.vue) conservent leurs optimisations légitimes
+
+## Conclusion
+
+La suppression du débouncing et du cooldown dans MediaBrowser.vue simplifie le code tout en améliorant la réactivité de l'interface. Puisque le serveur contrôle déjà le flux SSE, ces mécanismes côté client étaient redondants et ajoutaient une latence artificielle.
+
+Le code est maintenant plus simple, plus réactif, et fait confiance au serveur pour contrôler la fréquence des événements SSE.
+
+## Fichiers modifiés
+- `pmoapp/webapp/src/components/pmocontrol/MediaBrowser.vue`
+
+## Lignes de code
+- **Supprimées**: ~35 lignes (logique de débouncing/cooldown)
+- **Ajoutées**: ~5 lignes (logique simplifiée)
+- **Net**: -30 lignes

+# Rapport Final : Implémentation du Shuffle de la Queue de Lecture
+
+## Résumé
+
+Implémentation complète de la fonctionnalité de shuffle (mélange aléatoire) de la queue de lecture pour les Music Renderers dans PMOMusic. Cette fonctionnalité permet de randomiser l'ordre des morceaux dans la queue et de redémarrer la lecture depuis le premier morceau.
+
+Au-delà de la fonctionnalité shuffle, ce travail a permis d'améliorer l'architecture en centralisant l'émission des événements SSE dans le `MusicRenderer` plutôt que dans le `ControlPoint`.
+
+## Travail effectué
+
+### Étape 1 : Implémentation de la méthode shuffle dans MusicRenderer
+
+**Fichier modifié** : `pmocontrol/src/music_renderer/musicrenderer.rs`
+
+Ajout de la méthode `shuffle_queue()` qui implémente la stratégie suivante :
+1. Détache la queue de lecture d'une playlist si celle-ci est attachée
+2. Arrête la lecture en cours
+3. Prend un snapshot de la queue actuelle
+4. Randomise l'ordre des morceaux avec `rand::seq::SliceRandom`
+5. Remplace la queue avec les items mélangés
+6. Redémarre la lecture au premier morceau
+
+**Dépendances ajoutées** :
+- `rand = "0.9"` dans `Cargo.toml` (workspace)
+- `rand = { workspace = true }` dans `pmocontrol/Cargo.toml`
+
+### Étape 2 : API REST et documentation OpenAPI
+
+**Fichiers modifiés** :
+- `pmocontrol/src/pmoserver_ext.rs` : Ajout du handler `shuffle_queue`
+- `pmocontrol/src/openapi.rs` : Ajout du path dans la documentation OpenAPI
+
+**Endpoint créé** :
+```
+POST /api/control/renderers/{renderer_id}/queue/shuffle
+```
+
+**Réponses** :
+- `200` : Queue mélangée et lecture démarrée
+- `400` : Queue vide
+- `404` : Renderer non trouvé
+- `504` : Timeout de la commande
+- `500` : Erreur interne
+
+### Étape 3 : Interface Vue.js
+
+**Fichiers créés** :
+- `pmoapp/webapp/src/components/pmocontrol/ShuffleControl.vue` : Nouveau composant bouton shuffle
+
+**Fichiers modifiés** :
+- `pmoapp/webapp/src/services/pmocontrol/api.ts` : Ajout de la méthode `shuffleQueue()`
+- `pmoapp/webapp/src/components/unified/BottomTabBar.vue` : Intégration du bouton shuffle à côté du timer
+
+**Design** :
+- Bouton circulaire avec icône Shuffle (lucide-vue-next)
+- Style cohérent avec le bouton Timer existant
+- Animation de chargement pendant l'exécution
+- Responsive (taille réduite sur mobile)
+
+### Étape 4 : Émission automatique des événements SSE (Round 3)
+
+**Problème identifié** : L'interface utilisateur ne se mettait pas à jour après un shuffle car aucun événement `QueueUpdated` n'était émis.
+
+**Solution implémentée** : Le `MusicRenderer` stocke maintenant une référence optionnelle au `RendererEventBus` et émet automatiquement un événement `QueueUpdated` après chaque modification de la queue.
+
+**Fichiers modifiés** :
+
+| Fichier | Modification |
+|---------|--------------|
+| `pmocontrol/src/music_renderer/musicrenderer.rs` | Ajout du champ `event_bus: Option<RendererEventBus>`, constructeur `from_renderer_info_with_bus()`, méthode helper `emit_queue_updated()`, implémentation manuelle de `Debug` |
+| `pmocontrol/src/registry.rs` | Passage du `RendererEventBus` lors de la création des renderers via `from_renderer_info_with_bus()` |
+
+**Méthodes qui émettent désormais `QueueUpdated`** :
+- `enqueue_items()` - Ajout d'items à la queue
+- `sync_queue()` - Synchronisation de la queue
+- `clear_queue()` - Vidage de la queue
+- `replace_queue()` - Remplacement complet de la queue (utilisé par `shuffle_queue()`)
+- `play_next_from_queue()` - Passage au morceau suivant
+- `play_from_index()` - Lecture à un index spécifique
+
+### Étape 5 : Refactoring des émissions d'événements (Round 4)
+
+**Objectif** : Centraliser les émissions d'événements dans le `MusicRenderer` et supprimer les émissions redondantes du `ControlPoint`.
+
+**Principe** : Puisque le `MusicRenderer` a maintenant accès au `RendererEventBus`, il est plus cohérent et maintenable que les événements soient émis au niveau du renderer plutôt que dispersés dans le `ControlPoint`.
+
+#### Événements `QueueUpdated`
+
+**Modifications dans `ControlPoint`** - Suppression des émissions redondantes dans :
+- `clear_queue()`
+- `enqueue_items_with_mode()`
+- `shuffle_queue()`
+- `play_next_from_queue()`
+
+#### Événements `BindingChanged`
+
+**Modifications dans `MusicRenderer`** :
+- `set_playlist_binding()` : Émet `BindingChanged` uniquement si le binding change réellement
+- `clear_playlist_binding()` : Émet `BindingChanged` uniquement s'il y avait un binding à supprimer
+- Ajout de la méthode helper `emit_binding_changed()`
+
+**Modifications dans `ControlPoint`** :
+- `attach_queue_to_playlist_internal()` : Suppression de l'émission manuelle de `BindingChanged`
+- `detach_playlist_binding()` : Suppression de l'émission manuelle, utilisation de `clear_playlist_binding()` au lieu de `set_playlist_binding(None)`
+
+## Liste complète des fichiers modifiés
+
+| Fichier | Type de modification |
+|---------|---------------------|
+| `Cargo.toml` (workspace) | Ajout dépendance `rand` |
+| `pmocontrol/Cargo.toml` | Ajout dépendance `rand` |
+| `pmocontrol/src/music_renderer/musicrenderer.rs` | Ajout `shuffle_queue()`, `event_bus`, émission d'événements automatique |
+| `pmocontrol/src/control_point.rs` | Suppression des émissions d'événements redondantes |
+| `pmocontrol/src/registry.rs` | Passage du `RendererEventBus` lors de la création des renderers |
+| `pmocontrol/src/pmoserver_ext.rs` | Ajout handler REST `shuffle_queue` |
+| `pmocontrol/src/openapi.rs` | Ajout documentation OpenAPI |
+| `pmoapp/webapp/src/services/pmocontrol/api.ts` | Ajout méthode API `shuffleQueue()` |
+| `pmoapp/webapp/src/components/unified/BottomTabBar.vue` | Intégration du bouton shuffle |
+
+## Fichiers créés
+
+| Fichier | Description |
+|---------|-------------|
+| `pmoapp/webapp/src/components/pmocontrol/ShuffleControl.vue` | Composant Vue.js du bouton shuffle |
+
+## Notes techniques
+
+- La méthode `shuffle_queue` détache automatiquement la playlist liée pour éviter que la queue soit écrasée par une mise à jour de la playlist
+- Le shuffle utilise `rand::thread_rng()` pour une génération aléatoire de qualité
+- L'endpoint REST utilise le même pattern async que les autres commandes de transport (spawn_blocking + timeout)
+- Le timeout utilisé est `QUEUE_COMMAND_TIMEOUT` (10 secondes)
+- L'émission des événements SSE est automatique via le `RendererEventBus` intégré au `MusicRenderer`
+- L'implémentation manuelle de `Debug` pour `MusicRenderer` est nécessaire car `RendererEventBus` n'implémente pas `Debug`
+- Les événements ne sont émis que lorsqu'il y a un changement effectif (pas d'événement `BindingChanged` si le binding était déjà `None`)
+
+## Améliorations architecturales
+
+Ce travail a posé les bases d'une meilleure architecture où le `MusicRenderer` est responsable de l'émission de ses propres événements. Une tâche de suivi a été créée (`Blackboard/Todo/stateful_music_renderer.md`) pour aller plus loin et rendre le `MusicRenderer` complètement stateful avec son propre thread de surveillance.

+# Rapport : Implémentation des items épinglables dans PMOcache
+
+## Résumé
+
+Implémentation réussie de la fonctionnalité d'items épinglables dans la crate PMOcache, permettant de protéger certains items de l'éviction automatique par la politique LRU. Cette fonctionnalité inclut également un système de TTL (Time To Live) avec une règle métier empêchant qu'un item soit à la fois épinglé et avec un TTL.
+
+## Modifications apportées
+
+### 1. Structure de la base de données (`pmocache/src/db.rs`)
+
+#### Modification du schéma de la table `asset`
+
+Ajout de deux nouvelles colonnes :
+
+```sql
+CREATE TABLE IF NOT EXISTS asset (
+    pk TEXT PRIMARY KEY,
+    collection TEXT,
+    id TEXT,
+    hits INTEGER DEFAULT 0,
+    last_used TEXT,
+    lazy_pk TEXT,
+    pinned INTEGER DEFAULT 0 CHECK (pinned IN (0, 1)),
+    ttl_expires_at TEXT
+)
+```
+
+- **`pinned`** : Booléen (0 ou 1) indiquant si l'item est épinglé
+- **`ttl_expires_at`** : Date/heure d'expiration au format RFC3339 (optionnel)
+
+#### Mise à jour de la structure `CacheEntry`
+
+Ajout des champs correspondants :
+
+```rust
+pub struct CacheEntry {
+    // ... champs existants ...
+    pub pinned: bool,
+    pub ttl_expires_at: Option<String>,
+    // ...
+}
+```
+
+#### Nouvelles méthodes dans `DB`
+
+##### Gestion du comptage
+
+- **`count_unpinned()`** : Compte uniquement les items non épinglés
+  - Les items épinglés ne comptent pas dans la limite du cache
+
+##### Gestion du pinning
+
+- **`pin(pk: &str)`** : Épingle un item
+  - Vérifie que l'item n'a pas de TTL défini (règle métier)
+  - Retourne une erreur si le TTL est déjà défini
+  
+- **`unpin(pk: &str)`** : Désépingle un item
+
+- **`is_pinned(pk: &str)`** : Vérifie si un item est épinglé
+
+##### Gestion du TTL
+
+- **`set_ttl(pk: &str, expires_at: &str)`** : Définit le TTL d'un item
+  - Vérifie que l'item n'est pas épinglé (règle métier)
+  - Retourne une erreur si l'item est épinglé
+  
+- **`clear_ttl(pk: &str)`** : Supprime le TTL d'un item
+
+- **`get_expired()`** : Récupère tous les items dont le TTL est dépassé
+
+##### Modification de `get_oldest()`
+
+La requête SQL exclut maintenant les items épinglés :
+
+```sql
+SELECT ... FROM asset
+WHERE pinned = 0
+ORDER BY last_used ASC, hits ASC
+LIMIT ?1
+```
+
+### 2. Logique du cache (`pmocache/src/cache.rs`)
+
+#### Méthodes publiques ajoutées
+
+```rust
+pub async fn pin(&self, pk: &str) -> Result<()>
+pub async fn unpin(&self, pk: &str) -> Result<()>
+pub async fn is_pinned(&self, pk: &str) -> Result<bool>
+pub async fn set_ttl(&self, pk: &str, expires_at: &str) -> Result<()>
+pub async fn clear_ttl(&self, pk: &str) -> Result<()>
+```
+
+#### Modification de `enforce_limit()`
+
+La politique d'éviction a été améliorée :
+
+1. **Suppression prioritaire des items expirés** : Les items dont le TTL est dépassé sont supprimés en premier
+2. **Comptage des items non épinglés** : Utilise `count_unpinned()` au lieu de `count()`
+3. **Protection des items épinglés** : Ils ne peuvent pas être évincés par LRU
+4. **Logging amélioré** : Messages distincts pour les items expirés et l'éviction LRU
+
+### 3. Tests (`pmocache/tests/test_pinnable.rs`)
+
+Création d'une suite complète de tests (9 tests, tous passants) :
+
+1. **`test_pin_unpin`** : Vérifie l'épinglage et le désépinglage basiques
+2. **`test_pinned_excluded_from_lru`** : Vérifie que les items épinglés ne sont pas évincés
+3. **`test_pinned_count_separately`** : Vérifie le comptage séparé des items épinglés
+4. **`test_cannot_pin_with_ttl`** : Vérifie la règle métier TTL → pas de pinning
+5. **`test_cannot_set_ttl_when_pinned`** : Vérifie la règle métier pinned → pas de TTL
+6. **`test_ttl_expiration`** : Vérifie la suppression automatique des items expirés
+7. **`test_clear_ttl`** : Vérifie la suppression du TTL
+8. **`test_get_expired`** : Vérifie la récupération des items expirés
+9. **`test_cache_entry_fields`** : Vérifie les valeurs des champs dans `CacheEntry`
+
+## Règles métier implémentées
+
+### Incompatibilité TTL ↔ Pinned
+
+Un item ne peut pas être à la fois épinglé ET avoir un TTL :
+
+- **Si TTL défini** : `pin()` retourne une erreur
+- **Si épinglé** : `set_ttl()` retourne une erreur
+
+Cette règle garantit une sémantique claire :
+- **Épinglé** = permanent, protégé de l'éviction
+- **TTL** = temporaire, sera supprimé à expiration
+
+### Comptage des items
+
+Les items épinglés sont **exclus** du comptage de la limite du cache :
+
+- Un cache de limite 100 peut contenir 100 items non épinglés + N items épinglés
+- Seuls les items non épinglés sont pris en compte pour l'éviction LRU
+
+### Ordre de suppression lors de `enforce_limit()`
+
+1. **Items expirés (TTL dépassé)** : supprimés en priorité
+2. **Items LRU** : si la limite est toujours dépassée, suppression des plus vieux items **non épinglés**
+
+## Compatibilité
+
+### Migration de base de données
+
+**Aucune migration nécessaire** : Les colonnes `pinned` et `ttl_expires_at` ont des valeurs par défaut :
+- `pinned = 0` (non épinglé)
+- `ttl_expires_at = NULL` (pas de TTL)
+
+Les bases existantes seront automatiquement mises à jour au prochain démarrage via le `CREATE TABLE IF NOT EXISTS` avec les nouvelles colonnes.
+
+### Rétrocompatibilité du code
+
+Toutes les méthodes existantes continuent de fonctionner sans modification :
+- Les items existants ne sont pas épinglés par défaut
+- Le comportement LRU standard reste identique pour les items non épinglés
+
+## Exemples d'utilisation
+
+### Utilisation programmatique (Rust)
+
+```rust
+use pmocache::{Cache, CacheConfig};
+use chrono::{Duration, Utc};
+
+// Créer un cache
+let cache = Cache::<MyConfig>::new("./cache", 100).unwrap();
+
+// Ajouter un fichier
+let pk = cache.add_from_url("https://example.com/file.dat", None).await?;
+
+// Épingler pour protéger de l'éviction
+cache.pin(&pk).await?;
+
+// Ou définir un TTL de 24 heures
+let expires_at = (Utc::now() + Duration::hours(24)).to_rfc3339();
+cache.set_ttl(&pk2, &expires_at).await?;
+
+// Vérifier le statut
+if cache.is_pinned(&pk).await? {
+    println!("Fichier protégé");
+}
+```
+
+### Utilisation via l'API REST

+{
+  "pk": "1a2b3c4d5e6f7a8b",
+  "message": "TTL set successfully for item '1a2b3c4d5e6f7a8b'"
+}
+
+Response 409 CONFLICT (si épinglé):
+{
+  "error": "CONFLICT",
+  "message": "Cannot set TTL on a pinned item. Unpin first."
+}
+
+Response 400 BAD REQUEST (format invalide):

+# Rapport : Suppression de la logique de débouncing SSE
+
+**Date**: 2026-01-12
+**Tâche**: WeabApp_debouncingSSE.md
+
+## Objectif
+
+Supprimer la logique de débouncing inutile sur le canal SSE de l'application web PMOControl, puisque le serveur contrôle déjà le flux des événements.
+
+## Analyse préalable
+
+J'ai identifié trois endroits avec des mécanismes de temporisation dans l'application web :
+
+### 1. MediaBrowser.vue - Débouncing SSE (À SUPPRIMER ✓)
+- **Débouncing**: 200ms après invalidation du cache
+- **Cooldown**: 2 secondes entre les rechargements
+- **Justification originale**: "dédupliquer les événements SSE dans le même batch (polling 500ms)"
+- **Problème**: Cette logique est redondante puisque le serveur contrôle déjà le flux SSE
+
+### 2. useRenderers.ts - Smart fetching (À CONSERVER ✓)
+- **Mécanisme**: Comparaison des timestamps `lastEventAt` vs `lastSnapshotAt`
+- **But**: Éviter de refetch un snapshot déjà à jour
+- **Justification**: Ce n'est PAS du débouncing, c'est une optimisation intelligente qui évite des appels API inutiles
+
+### 3. VolumeControl.vue - UI debouncing (À CONSERVER ✓)
+- **Débouncing**: 300ms sur les changements de volume
+- **But**: Réduire les appels API pendant que l'utilisateur fait glisser le curseur
+- **Justification**: Débouncing légitime pour l'interface utilisateur
+
+## Modifications effectuées
+
+### Fichier modifié: `pmoapp/webapp/src/components/pmocontrol/MediaBrowser.vue`
+
+#### 1. Suppression des variables de débouncing (ligne ~27)
+
+**Avant**:
+```typescript
+// Flags pour gérer le rechargement automatique avec debounce et cooldown
+const isRefreshing = ref(false);
+const refreshTimeoutId = ref<number | null>(null);
+const lastRefreshTime = ref<number>(0);
+const REFRESH_COOLDOWN_MS = 2000; // Ne pas recharger plus d'une fois toutes les 2 secondes
+```
+
+**Après**:
+```typescript
+// Flag pour gérer le rechargement automatique
+const isRefreshing = ref(false);
+```
+
+#### 2. Simplification du watcher de cache (ligne ~53)
+
+**Avant**:
+```typescript
+// Recharger automatiquement si le cache est invalidé (ex: après un ContainersUpdated SSE)
+// Cela se produit notamment quand on clique sur "Lire maintenant" sur une playlist,
+// ce qui déclenche un événement ContainersUpdated qui invalide le cache
+// Utilise un debounce de 3 secondes pour regrouper les multiples invalidations
+// et un cooldown de 5 secondes pour éviter les rechargements successifs
+watch(
+    () => browseData.value,
+    (data) => {
+        if (!data && props.containerId && !loading.value) {
+            // Vérifier le cooldown: ignorer si on a rechargé il y a moins de 5 secondes
+            const timeSinceLastRefresh = Date.now() - lastRefreshTime.value;
+            if (timeSinceLastRefresh < REFRESH_COOLDOWN_MS) {
+                console.log(
+                    `[MediaBrowser] Cache invalidé mais cooldown actif (${Math.round((REFRESH_COOLDOWN_MS - timeSinceLastRefresh) / 1000)}s restantes), rechargement ignoré`,
+                );
+                return;
+            }
+
+            // Annuler tout timeout en cours
+            if (refreshTimeoutId.value !== null) {
+                clearTimeout(refreshTimeoutId.value);
+            }
+
+            // Planifier le rechargement après 200ms
+            refreshTimeoutId.value = window.setTimeout(async () => {
+                if (!isRefreshing.value) {
+                    console.log(
+                        `[MediaBrowser] Cache invalidé pour ${props.serverId}/${props.containerId}, rechargement après debounce...`,
+                    );
+                    isRefreshing.value = true;
+                    await browseContainer(
+                        props.serverId,
+                        props.containerId,
+                        false,
+                    );
+                    lastRefreshTime.value = Date.now();
+                    isRefreshing.value = false;
+                    refreshTimeoutId.value = null;
+                }
+            }, 200);
+        }
+    },
+);
+```
+
+**Après**:
+```typescript
+// Recharger automatiquement si le cache est invalidé (ex: après un ContainersUpdated SSE)
+// Cela se produit notamment quand on clique sur "Lire maintenant" sur une playlist,
+// ce qui déclenche un événement ContainersUpdated qui invalide le cache
+// Le serveur contrôle déjà le flux SSE, pas besoin de debouncing côté client
+watch(
+    () => browseData.value,
+    async (data) => {
+        // Si browseData devient undefined alors que containerId est présent,
+        // et qu'on n'est pas déjà en train de charger, recharger immédiatement
+        if (!data && props.containerId && !loading.value && !isRefreshing.value) {
+            console.log(
+                `[MediaBrowser] Cache invalidé pour ${props.serverId}/${props.containerId}, rechargement...`,
+            );
+            isRefreshing.value = true;
+            await browseContainer(props.serverId, props.containerId, false);
+            isRefreshing.value = false;
+        }
+    },
+);
+```
+
+## Résultats
+
+### Changements de comportement
+- **Avant**: Délai de 200ms + cooldown de 2s entre les rechargements de cache
+- **Après**: Rechargement immédiat dès l'invalidation du cache
+- **Impact**: Réactivité améliorée de l'interface, les mises à jour apparaissent immédiatement
+
+### Réduction de complexité
+- **3 variables supprimées**: `refreshTimeoutId`, `lastRefreshTime`, `REFRESH_COOLDOWN_MS`
+- **Logique simplifiée**: De ~40 lignes à ~10 lignes dans le watcher
+- **Code plus lisible**: Intention claire sans mécanismes de temporisation complexes
+
+### Tests
+- ✓ Le projet compile sans erreurs TypeScript
+- ✓ Le flag `isRefreshing` empêche toujours les rechargements concurrents
+- ✓ Les autres composants (useRenderers.ts, VolumeControl.vue) conservent leurs optimisations légitimes
+
+## Conclusion
+
+La suppression du débouncing et du cooldown dans MediaBrowser.vue simplifie le code tout en améliorant la réactivité de l'interface. Puisque le serveur contrôle déjà le flux SSE, ces mécanismes côté client étaient redondants et ajoutaient une latence artificielle.
+
+Le code est maintenant plus simple, plus réactif, et fait confiance au serveur pour contrôler la fréquence des événements SSE.
+
+## Fichiers modifiés
+- `pmoapp/webapp/src/components/pmocontrol/MediaBrowser.vue`
+
+## Lignes de code
+- **Supprimées**: ~35 lignes (logique de débouncing/cooldown)
+- **Ajoutées**: ~5 lignes (logique simplifiée)
+- **Net**: -30 lignes

+# Rapport : Documentation d'implémentation d'une nouvelle MusicSource
+
+## Objectif
+
+Créer une documentation complète et pratique pour guider l'implémentation d'une nouvelle source musicale dans l'écosystème PMOMusic.
+
+## Travail réalisé
+
+### 1. Analyse des sources existantes
+
+J'ai analysé deux implémentations de référence :
+
+- **pmoparadise/src/source.rs** : Source dynamique avec FIFO (radio streaming)
+- **pmoqobuz/src/source.rs** : Source catalogue avec playlists lazy
+
+Ainsi que la documentation du trait :
+
+- **pmosource/README.md** : Vue d'ensemble du trait MusicSource
+- **pmosource/ARCHITECTURE.md** : Architecture et design decisions
+
+### 2. Identification des patterns principaux
+
+Deux patterns majeurs ont été identifiés :
+
+#### Pattern 1 : Source dynamique FIFO (Radio Paradise)
+
+**Caractéristiques :**
+- Flux continu de tracks avec capacité limitée
+- Suppression automatique des plus anciens
+- Callbacks sur playlists pour détecter les changements
+- Notification du ContentDirectory via notifier injecté
+- Adaptation des IDs playlist → schema source
+
+**Éléments clés :**
+```rust
+update_counter: Arc<RwLock<u32>>
+last_change: Arc<RwLock<SystemTime>>
+callback_tokens: Arc<Mutex<Vec<u64>>>
+container_notifier: Option<Arc<dyn Fn(&[String]) + Send + Sync>>
+```
+
+#### Pattern 2 : Source catalogue lazy (Qobuz)
+
+**Caractéristiques :**
+- Catalogue vaste avec navigation hiérarchique
+- Cache lazy pour audio, eager pour covers
+- Playlists créées à la demande avec TTL
+- LazyProvider pour télécharger l'audio à la lecture
+- Métadonnées riches stockées dans le cache
+
+**Éléments clés :**
+```rust
+SourceCacheManager centralisé
+QobuzLazyProvider implémentant LazyProvider
+Playlists avec rôle Album et TTL de 7 jours
+Adaptation IDs avec metadata source_track_id
+```

+```
+
+Exemples concrets de Radio Paradise et Qobuz fournis.
+
+#### Adaptation des IDs
+
+Code complet pour adapter les items de playlist au schema de la source :
+- Extraction du cache_pk depuis l'URL
+- Récupération du source_track_id depuis metadata
+- Reconstruction de l'ID correct
+- Normalisation des URLs (relatives → absolues)
+- Ajout de champs requis (genre)
+
+#### Cache lazy vs eager
+
+Stratégie claire :
+- **Covers** : Cache eager (petit, UI en a besoin immédiatement)
+- **Audio** : Cache lazy (grand, téléchargé à la demande)
+
+#### Thread Safety
+
+Règles explicites :
+- `Arc<RwLock<>>` pour état mutable partagé
+- `tokio::sync::RwLock` pour async
+- Éviter `Rc<>`, `RefCell` (non thread-safe)
+- Implémenter `Clone` via `Arc<>`
+
+#### Compatibilité UPnP
+
+Points de vigilance :
+- Genre obligatoire pour certains clients (gupnp-av-cp)
+- URLs absolues uniquement
+- Protocol Info correct pour FLAC
+- Duration au format `H:MM:SS`
+- childCount optionnel mais recommandé
+
+### 5. Code d'exemple complet
+
+Le document contient des exemples de code complets et fonctionnels pour :
+
+1. **Structure de base** : définition de la struct et implémentation basique
+2. **Navigation** : root_container et browse avec pattern matching
+3. **Résolution URI** : avec fallback cache → original
+4. **FIFO** : append_track, remove_oldest, callbacks
+5. **Adaptation IDs** : fonction complète d'adaptation
+6. **LazyProvider** : implémentation personnalisée
+7. **Conversion DIDL** : traits ToDIDLContainer et ToDIDLItem
+
+## Couverture des besoins
+
+### Sources couvertes
+
+- ✅ Radio Paradise : source dynamique FIFO
+- ✅ Qobuz : source catalogue lazy

+
+## Limitations et améliorations futures
+
+### Limitations actuelles
+
+1. **Search** : Pas d'exemple détaillé de search (optionnel dans le trait)
+2. **Authentification** : Mentionné mais pas d'exemple complet
+3. **Multi-format** : Pas d'exemple de source supportant plusieurs formats
+4. **Offline** : Pas de pattern pour source offline/synchronisation
+
+### Améliorations possibles
+
+1. Ajouter un exemple complet de search avec filtres
+2. Documenter l'intégration avec un système d'auth OAuth
+3. Ajouter un pattern pour sources multi-formats (FLAC/MP3/AAC)
+4. Documenter la gestion offline avec synchronisation
+
+## Fichiers créés
+
+- `Blackboard/Architecture/music_source.md` : Documentation complète (15 sections, ~800 lignes)
+
+## Conclusion
+
+Le document créé fournit un guide complet et pratique pour implémenter une nouvelle MusicSource. Il combine :
+
+- **Théorie** : Architecture, design patterns, principes
+- **Pratique** : Code complet, exemples réels, checklist
+- **Référence** : Schemas d'Object ID, intégrations, compatibilité

+# Rapport : Documentation du pattern pmoserver_ext
+
+## Contexte
+
+Documentation du pattern d'extension du PMOServer à travers plusieurs itérations basées sur les retours utilisateur.
+
+## Travail réalisé
+
+### Analyse des fichiers sources
+
+Les fichiers suivants ont été analysés pour extraire le pattern :
+
+- `pmoapp/src/lib.rs` : Pattern SPA avec RustEmbed
+- `pmocontrol/src/pmoserver_ext.rs` : API REST avec Control Point (1506+ lignes)
+- `pmoparadise/src/pmoserver_ext.rs` : API REST simple avec client externe
+- `pmoaudiocache/src/lib.rs` : Extension avec cache et fichiers
+- `pmomediaserver/src/paradise_streaming.rs` : Extension complexe avec streaming
+
+### Round 1 : Document initial
+
+Premier jet documentant exhaustivement tous les aspects des extensions (~850 lignes).
+
+### Round 2 : Recentrage sur le pattern
+
+**Annotation** : "se recentrer sur le sujet principal"
+
+**Actions** :
+- Réduction de ~850 à ~400 lignes
+- Suppression des digressions (OpenAPI détaillé, handlers spécifiques)
+- Focus sur l'anatomie du pattern en 5 étapes
+- Ajout d'une checklist et d'un exemple minimal
+
+**Résultat** : Document focalisé sur l'implémentation du pattern uniquement.
+
+### Round 3 : Réintégration OpenAPI
+
+**Annotation** : "Je trouve que le fait de devoir déclarer et documenter les URL dans OpenAPI / utopia était quelque chose d'important. Remets le."
+
+**Actions** :
+- Ajout d'une section complète "Documentation OpenAPI avec utoipa" (~260 lignes)
+- 5 sous-sections détaillées :
+  1. Configuration de base (dépendances Cargo)
+  2. Définition des schémas avec `#[derive(ToSchema)]`
+  3. Annotation des handlers avec `#[utoipa::path]`
+  4. Création de la structure `#[derive(OpenApi)]`
+  5. Exemple complet extrait de Radio Paradise
+- Mise à jour de la checklist avec section "Documentation OpenAPI"
+- Ajout des dépendances `utoipa` et `serde` dans la section références
+
+**Positionnement** : Section insérée après "Méthodes disponibles du serveur" et avant "Patterns courants", car elle fait partie intégrante de l'implémentation.
+
+## Structure finale du document
+
+1. **Vue d'ensemble** : Principe du pattern
+2. **Anatomie d'une extension** : 5 étapes détaillées
+3. **Méthodes disponibles du serveur** : API de `pmoserver::Server`

+# Règles de développement PMOMusic
+
+## Contexte projet
+
+**PMOMusic** : Système audio HiFi basé sur UPnP/DLNA (LossLess/Bit-Perfect uniquement).
+
+**Technologies** :
+- Backend : Rust
+- Frontend : Vue.js (TypeScript/JavaScript)
+
+**Composants** : Media Server, Control Point, Media Renderer
+
+**Développement** : Collaboration humain-LLM (Claude/ChatGPT/Ollama)
+
+---
+
+## Règles Rust (Cargo workspace)
+
+### Gestion des dépendances
+
+**⚠️ OBLIGATOIRE** : Les dépendances doivent être ajoutées au niveau **workspace** autant que possible.
+
+1. Ajouter la dépendance dans `Cargo.toml` racine (section `[workspace.dependencies]`)
+2. Référencer avec `{ workspace = true }` dans le `Cargo.toml` de la crate
+
+**Exemple** :
+```toml
+# Cargo.toml (racine workspace)
+[workspace.dependencies]
+rand = "0.9"
+
+# pmocontrol/Cargo.toml
+[dependencies]
+rand = { workspace = true }
+```
+
+**Exceptions** : Dépendances spécifiques à une seule crate avec version très particulière.
+
+---
+
+## Prérequis des tâches
+
+### Spécification des crates cibles
+
+**⚠️ CRITIQUE** : Le LLM doit **REFUSER** d'exécuter une tâche si la ou les crates concernées ne sont pas explicitement spécifiées dans le fichier `Todo/{nom}.md`.
+
+**Informations requises** :
+- Nom de la ou des crates à modifier
+- Chemin relatif si nécessaire (ex: `pmocontrol/src/...`)
+
+**En cas d'absence** :
+- Le LLM demande clarification à l'humain
+- Ne pas deviner ou supposer les crates concernées

+    REPORT -->|Humain décide| DISCUSS[ToDiscuss]
+    DISCUSS -->|Reprise travail| REPORT
+```
+
+### Règles strictes
+
+#### 1. Phase de réflexion (ToThinkAbout)
+- **Collaboration** : Humain et LLM peuvent modifier
+- **But** : Explorer idées, définir architecture
+- **Sortie** : Documents de spécification → `Todo/`
+
+#### 2. Phase de réalisation (Todo → Report)
+- **Input** : Fichier `Todo/{nom}.md`
+- **Action** : LLM implémente la tâche
+- **Output** : Fichier `Report/{nom}.md` (même nom obligatoire)
+- **Contenu du rapport** :
+  - Résumé du travail effectué
+  - Liste des fichiers créés/modifiés
+  - **INTERDIT** : Rapport détaillé dans la discussion (uniquement dans `Report/`)
+
+#### 3. Décision humaine (Report → Done ou ToDiscuss)
+
+**⚠️ CRITIQUE** : Seul l'humain décide de la destination. Le LLM ne doit JAMAIS déplacer ou classer une tâche.
+
+**Cas 1 : Tâche complète** → `Done/`
+- Humain déplace `Todo/{nom}.md` → `Done/{nom}.md`
+- LLM crée une synthèse (tâche originale + rapport)
+- Contenu final dans `Done/{nom}.md`
+
+**Cas 2 : Tâche incomplète** → `ToDiscuss/`
+- Humain déplace `Todo/{nom}.md` → `ToDiscuss/{nom}.md`
+- Humain ajoute annotations/remarques dans `ToDiscuss/{nom}.md`
+- Lors de la reprise :
+  - LLM lit les annotations
+  - Complète `Report/{nom}.md` avec les modifications
+  - Nouveau cycle de validation
+
+#### 4. Documentation architecture (Architecture/)
+- Contient les documents d'architecture validés et stables
+- Référence pour patterns de code (ex: `pmoconfig_ext.md`, `pmoserver_ext.md`)
+- Ne pas modifier sans validation explicite
+

+| `make jjnew` | Nouveau commit | Documente le commit actuel (`jj auto-describe`) puis `jj new` |
+| `make jjpush` | Push vers Git | Documente le commit puis `jj git push --change @`<br/>→ Crée branche + PR sur le serveur |
+| `make jjfetch` | Récupération | `jj git fetch` puis `jj new main@origin`<br/>→ Après validation du PR |
+
+### Gestion version
+
+- **Source de vérité** : `PMOMusic/Cargo.toml`
+- **Sync** : `version.txt` (généré par Makefile)
+- **Incrémentation** : `make bump-version` (avant `jjpush`)

+
+## Checklist LLM
+
+### Avant de commencer une tâche
+- [ ] Lire `Todo/{nom}.md`
+- [ ] Vérifier les références à `Architecture/` si mentionnées
+- [ ] Comprendre les contraintes (HiFi, LossLess, UPnP/DLNA)
+
+### Pendant la réalisation
+- [ ] Suivre les patterns d'architecture existants
+- [ ] Utiliser Rust (backend) ou Vue.js/TypeScript (frontend)
+- [ ] Tester le code si applicable
+
+### Après la réalisation
+- [ ] Créer `Report/{nom}.md` (même nom que la tâche)

+
+La crâte PMOcache, implémente un system de cache qui pourrait être étendu pour permettre une utilisation plus large. L'idée est de modifier les règles de déletion des items. Actuellement le cache a une capacité maximale. Et les items ont des TTL, qui peuvent être non définies. Lorsque le cash est plein, les plus vieux items en termes d'utilisation ou ceux qui ont dépassé leur TTL peuvent être détruits. Je propose de rajouter une fonctionnalité qui permet d'épingler certains items pour les rendre non destructibles. Ils pourraient aussi sortir du comptage général des items pour savoir si le cache est plein.
+
+Il faudra modifier la structure de la base de données. Ajouter une colonne indiquant cette propriété. Mettre une règle métier en disant qu'on ne peut pas être à la fois épinglés et avec un TTL.
+
+On se moque de maintenir la compatibilité avec la base de données actuelle, il n'y a pas à prévoir de phase de transition. Nous sommes en période de développement.

+# MusicBoxSource : Bibliothèque musicale universelle
+
+Créer une **"boîte à musique"** personnelle : un catalogue unifié de morceaux provenant de n'importe quelle source (Qobuz, URLs, fichiers locaux, Radio Paradise, etc.), avec taxonomie de tags et playlists intelligentes.
+
+---
+
+## 🎯 Vision
+
+### Concept
+
+**MusicBoxSource** est une bibliothèque musicale curatoriale qui permet de :
+- **Collecter** : Ajouter des morceaux depuis n'importe quelle source PMOMusic ou URL
+- **Organiser** : Classifier avec une taxonomie de tags extensible
+- **Requêter** : Créer des playlists statiques et smart playlists (requêtes dynamiques)
+- **Exposer** : Servir via UPnP/DIDL-Lite avec navigation multi-axes
+
+### Différence avec `pmoplaylist`
+
+- **`pmoplaylist`** : Playlists FIFO **éphémères** pour sources live (Radio Paradise)
+- **`pmomusicbox`** : Bibliothèque **persistante** cross-sources avec métadonnées enrichies

+## 🔍 Smart Playlists (Query DSL)
+
+### Concept
+
+Les smart playlists sont des **requêtes sauvegardées** qui génèrent dynamiquement une liste de tracks.
+
+### Structure de requête (JSON)
+
+```json
+{
+  "include_all_tags": ["mood:energetic", "genre:rock"],
+  "exclude_tags": ["mood:melancholic"],
+  "year_min": 1980,
+  "year_max": 1989,
+  "min_rating": 4,
+  "lossless_only": true,
+  "order_by": "play_count",
+  "order": "desc",
+  "limit": 50
+}
+```
+
+### Traduction SQL
+
+```sql
+SELECT * FROM music_items
+WHERE id IN (
+    SELECT item_id FROM item_tags WHERE tag_id IN ('mood:energetic', 'genre:rock')
+    GROUP BY item_id HAVING COUNT(DISTINCT tag_id) = 2  -- ALL tags
+)
+AND id NOT IN (
+    SELECT item_id FROM item_tags WHERE tag_id = 'mood:melancholic'
+)
+AND year BETWEEN 1980 AND 1989
+AND rating >= 4
+AND codec IN ('flac', 'alac')
+ORDER BY play_count DESC

+## 🔌 Intégration avec l'écosystème PMOMusic
+
+### Avec pmoaudiocache
+
+- Import → Déclencher cache automatique (si `auto_cache: true`)
+- `resolve_uri()` → Retourner URI cachée si disponible
+
+### Avec pmocovers
+
+- Import → Télécharger cover art
+- Browse → Inclure `album_art` dans DIDL-Lite
+
+### Avec pmoserver (feature `server`)
+
+- API REST pour manipulation (CRUD items, tags, playlists)
+- SSE pour notifications de changements
+- Endpoints OpenAPI (utoipa)
+
+---
+
+## 📝 Plan d'implémentation (Phases)
+
+### Phase 1 : Fondations
+- Schéma SQLite complet
+- Crate `pmojspf` (parser playlists)
+- CRUD basique dans `pmomusicbox` (items, tags)
+- Taxonomie par défaut
+- Import URL simple
+- Extension pmoconfig
+
+### Phase 2 : Import cross-sources
+- Import depuis MusicSource (Qobuz, Paradise)
+- Import playlists (JSPF/M3U8)
+- Intégration caches (audio, covers)
+- Crate `pmolocal` (fichiers locaux)
+
+### Phase 3 : Smart Playlists
+- Query builder (DSL)
+- Exécuteur SQL
+- CRUD smart playlists
+- Export JSPF
+
+### Phase 4 : MusicSource UPnP
+- Implémentation trait `MusicSource`
+- Génération DIDL-Lite
+- Browse multi-axes (artist, album, tag)
+- Recherche full-text (FTS5)
+
+### Phase 5 : Fonctionnalités avancées
+- Statistiques d'écoute (play_count, last_played)
+- Auto-tagging (genre depuis métadonnées)
+- API REST (feature `server`)
+- Recommandations (items similaires)
+
+---
+
+## 🎯 Cas d'usage
+
+### Workflow typique
+
+1. **Découverte** : Écouter Radio Paradise, tomber sur un morceau génial
+2. **Ajout** : `musicbox.import_from_source(&paradise, "track-123")`
+3. **Organisation** : Ajouter tags `mood:chill`, `occasion:focus`
+4. **Playlist** : Smart playlist "Focus Music" avec requête `mood:chill + occasion:focus`
+5. **Écoute** : Naviguer dans UPnP → `musicbox/smart-playlists/Focus Music/`
+
+### Scénario : Bibliothèque mixte
+
+- Albums Qobuz haute résolution
+- Playlists M3U8 importées depuis iTunes
+- Fichiers FLAC locaux scannés
+- URLs de SoundCloud
+- Tracks Radio Paradise capturés
+
+**Tout unifié dans MusicBox, accessible via UPnP, organisé par tags.**

+
+## 📋 Décisions de conception
+
+### Format pivot : JSPF (JSON)
+
+**Choix** : JSPF comme format interne central
+- Métadonnées riches (title, creator, album, annotation, image, duration, etc.)
+- JSON natif avec serde (Rust-friendly)
+- Standard ouvert (Xiph.Org)
+- Extensible via champ `meta`
+
+**Formats supportés** :
+- ✅ **JSPF** (.jspf) - JSON, format natif
+- ✅ **XSPF** (.xspf) - XML, conversion vers JSPF
+- ✅ **M3U8** (.m3u8) - Texte, métadonnées limitées
+- ✅ **PLS** (.pls) - INI-like, très basique
+
+**Architecture** : 1 Writer (JSPF) + 4 Readers (JSPF, XSPF, M3U8, PLS) → Structure JSPF centrale
+
+```mermaid

+    JSPF[JSPF JSON] --> JR[JspfReader]

+    pub rel: String,
+    pub content: String,

+```
+
+#### Trait PlaylistReader
+
+```rust
+use std::io::Read;
+
+pub trait PlaylistReader {
+    fn read<R: Read>(reader: R) -> Result<Jspf>;
+    fn from_str(s: &str) -> Result<Jspf>;
+    fn from_file<P: AsRef<Path>>(path: P) -> Result<Jspf>;
+}
+```
+
+#### Implémentations des Readers
+
+##### JspfReader (✅ Simple - serde_json)
+
+```rust
+pub struct JspfReader;
+
+impl PlaylistReader for JspfReader {
+    fn read<R: Read>(reader: R) -> Result<Jspf> {
+        serde_json::from_reader(reader)
+            .map_err(|e| Error::ParseError(format!("JSON: {}", e)))
+    }
+}
+```
+
+**Dépendances** : `serde_json`
+
+##### XspfReader (⚠️ Complexe - xml-rs)
+
+**Approche** : Machine à états XML pour parser `<playlist>`, `<track>`, etc.
+
+**Alternative** : Utiliser la crate `xspf` existante puis convertir → JSPF
+
+```rust
+pub struct XspfReader;
+
+impl PlaylistReader for XspfReader {
+    fn read<R: Read>(reader: R) -> Result<Jspf> {
+        // Parser XML avec EventReader
+        // État : in_playlist, in_track, current_element
+        // Mapping: <title> → playlist.title, <track> → JspfTrack
+    }
+}
+```
+
+**Dépendances** : `xml-rs` ou réutiliser `xspf` crate
+
+##### M3uReader (⚙️ Modéré - ligne par ligne)
+
+**Format** :
+```m3u
+#EXTM3U
+#PLAYLIST:Ma Playlist Jazz
+#EXTINF:284,John Coltrane - Giant Steps
+#EXTART:John Coltrane
+#EXTALB:Giant Steps
+file:///music/coltrane.flac
+```
+
+```rust
+pub struct M3uReader;
+
+impl PlaylistReader for M3uReader {
+    fn read<R: Read>(reader: R) -> Result<Jspf> {
+        // BufReader ligne par ligne
+        // Parser #EXTINF:duration,artist - title
+        // Gérer extensions non-standard (#EXTART, #EXTALB, #EXTIMG)
+    }
+}
+```
+
+**Dépendances** : stdlib uniquement
+
+**Limitations** : Métadonnées pauvres, beaucoup de champs `None`
+
+##### PlsReader (⚙️ Modéré - format INI)
+
+**Format** :
+```ini
+[playlist]
+NumberOfEntries=2
+File1=file:///music/coltrane.flac
+Title1=John Coltrane - Giant Steps
+Length1=284
+```
+
+```rust
+pub struct PlsReader;
+
+impl PlaylistReader for PlsReader {
+    fn read<R: Read>(reader: R) -> Result<Jspf> {
+        // HashMap<index, (file, title, duration)>
+        // Parser FileN=..., TitleN=..., LengthN=...
+        // Trier par index et convertir en JspfTrack
+    }
+}
+```
+
+**Dépendances** : stdlib uniquement
+
+**Limitations** : File, Title, Length seulement
+
+#### JspfWriter
+
+```rust
+pub struct JspfWriter;
+
+impl JspfWriter {
+    pub fn write<W: Write>(jspf: &Jspf, writer: W) -> Result<()>;
+    pub fn write_pretty<W: Write>(jspf: &Jspf, writer: W) -> Result<()>;
+    pub fn to_string(jspf: &Jspf) -> Result<String>;
+    pub fn to_string_pretty(jspf: &Jspf) -> Result<String>;
+}
+```
+
+#### API publique
+
+```rust
+pub use model::{Jspf, JspfPlaylist, JspfTrack, JspfMeta, JspfAttribution};
+pub use reader::{PlaylistReader, JspfReader, XspfReader, M3uReader, PlsReader};
+pub use writer::JspfWriter;
+
+pub enum PlaylistFormat {
+    Jspf,
+    Xspf,
+    M3u8,
+    Pls,
+}
+
+impl PlaylistFormat {
+    pub fn from_extension(ext: &str) -> Option<Self>;
+}
+
+pub fn read_playlist<R: Read>(reader: R, format: PlaylistFormat) -> Result<Jspf>;
+```
+
+---
+
+### 2. Crate `pmoplaylists` (PlaylistSource)
+
+**Responsabilité** : Implémenter `MusicSource` pour servir playlists via UPnP
+
+#### Structures principales
+
+```rust
+pub struct PlaylistSource {
+    root_path: PathBuf,
+    playlists: Arc<RwLock<HashMap<String, ParsedPlaylist>>>,
+    containers: Arc<RwLock<HashMap<PathBuf, ContainerMetadata>>>,
+    watcher: Option<notify::RecommendedWatcher>,
+    base_url: String,
+    update_counter: Arc<RwLock<u32>>,
+    last_change: Arc<RwLock<SystemTime>>,
+}
+
+pub struct ParsedPlaylist {
+    pub metadata: PlaylistMetadata,
+    pub tracks: Vec<PlaylistTrack>,
+    pub source_path: PathBuf,
+    pub format: PlaylistFormat,
+}
+
+pub struct ContainerMetadata {
+    pub title: Option<String>,
+    pub description: Option<String>,
+    pub creator: Option<String>,
+    pub image: Option<String>,
+    pub date: Option<String>,
+    pub meta: Vec<MetaEntry>,
+}
+
+pub struct ContainerMetadataFile {
+    pub container: ContainerMetadata,
+}
+```
+
+#### Fonctionnalités
+
+1. **Scan hiérarchique** : Parser récursivement dossiers + `metadata.json` + playlists
+2. **Cache** : Éviter re-parsing (playlists + conteneurs)
+3. **Hot reload** : `notify` pour détecter changements
+4. **Browse UPnP** : Générer DIDL-Lite avec métadonnées conteneurs
+5. **Content resolution** : Résoudre URIs via `SourceCacheManager`
+6. **Cover art** : Servir images playlists, tracks, conteneurs
+
+#### Object IDs
+
+```
+playlists                                # Racine
+playlists:category:{path}                # Catégorie (dossier)
+playlists:playlist:{id}                  # Playlist
+playlists:playlist:{id}:track:{index}    # Track dans playlist
+```
+
+#### Gestion `metadata.json`
+
+```rust
+fn load_container_metadata(&self, dir_path: &Path) -> Result<ContainerMetadata> {
+    let metadata_path = dir_path.join("metadata.json");
+    
+    if metadata_path.exists() {
+        let content = fs::read_to_string(&metadata_path)?;
+        let file: ContainerMetadataFile = serde_json::from_str(&content)?;
+        Ok(file.container)
+    } else {
+        // Fallback : nom du répertoire
+        Ok(ContainerMetadata {
+            title: Some(dir_path.file_name()?.to_str()?.to_string()),
+            ..Default::default()
+        })
+    }
+}
+```

+## 🔌 Intégration MusicBrainz (optionnelle - Phase 2)
+
+### Crate recommandée : `musicbrainz_rs`
+
+[musicbrainz_rs](https://crates.io/crates/musicbrainz_rs) v0.5+
+- Client async/blocking
+- Rate limiting automatique (1 req/sec)
+- Support CoverArt Archive
+- MSRV: Rust 1.71.1
+
+### Cas d'usage
+
+1. **Résolution d'identifiants** :
+   ```json
+   {"identifier": ["musicbrainz://recording/abc123"], "title": null}
+   ```
+   → Récupérer métadonnées depuis MusicBrainz
+
+2. **Enrichissement playlists pauvres** : M3U8/PLS → MusicBrainz → métadonnées complètes
+
+3. **Cover art** : CoverArt Archive
+
+### Configuration
+
+```yaml
+sources:
+  playlists:
+    musicbrainz:
+      enabled: false
+      enrich_metadata: false
+      rate_limit_per_sec: 1
+```
+
+**Stratégie** :
+- **Phase 1 (MVP)** : Ne pas implémenter, stocker identifiants tel quel
+- **Phase 2** : Dépendance optionnelle, service asynchrone, configurable
+
+---
+
+## 📝 Prochaines étapes
+
+1. ✅ Choix format : JSPF central
+2. ✅ Modèle données : Structures JSPF
+3. ✅ Extension pmoconfig : Trait défini
+4. ⏳ **Implémenter `pmojspf`** :
+   - `JspfReader` (serde_json)
+   - `XspfReader` (xml-rs ou crate xspf)
+   - `M3uReader` (parsing ligne par ligne)
+   - `PlsReader` (format INI)
+   - `JspfWriter` (serde_json)
+5. ⏳ **Implémenter `pmoplaylists`** :
+   - `PlaylistSource` (trait `MusicSource`)
+   - Scan hiérarchique + cache
+   - Hot reload (notify)
+   - Browse UPnP (DIDL-Lite)
+   - Gestion `metadata.json`
+6. ⏳ Tests avec clients UPnP

+# Tâche : Rendre MusicRenderer complètement stateful
+
+## Objectif
+
+Refactoriser l'architecture pour que chaque `MusicRenderer` gère son propre état complet et son thread de surveillance, au lieu de déléguer le polling au `ControlPoint`.
+
+## Motivation
+
+1. **Encapsulation** - Tout l'état et le comportement d'un renderer au même endroit
+2. **Cohérence** - Les événements sont émis là où l'état change
+3. **Adaptabilité par backend** - Chaque backend peut avoir sa propre stratégie de surveillance (polling vs push pour OpenHome/Chromecast)
+4. **Auto-advance spécifique** - La logique d'auto-advance peut être adaptée par backend
+5. **Simplicité du ControlPoint** - Il devient un simple registry/coordinateur
+
+## Contraintes
+
+- Moins de 10 renderers simultanés → 10 threads de surveillance n'est pas un problème
+- Le transfert de queue et autres opérations multi-renderers n'impliquent pas de surveillance
+
+## Architecture cible
+
+### MusicRenderer
+
+Responsabilités :
+- Maintenir l'état complet du renderer (transport, volume, position, queue, binding)
+- Gérer son propre thread de surveillance (polling ou push selon le backend)
+- Émettre tous les événements (StateChanged, PositionChanged, VolumeChanged, MuteChanged, QueueUpdated, BindingChanged)
+- Gérer l'auto-advance de la queue (logique adaptée par backend)
+
+Nouveau champ :
+```rust
+pub struct MusicRenderer {
+    // ... champs existants ...
+    event_bus: Option<RendererEventBus>,
+    // Nouveau : état surveillé
+    watched_state: Arc<Mutex<WatchedState>>,
+    // Nouveau : handle du thread de surveillance
+    watcher_handle: Option<JoinHandle<()>>,
+}
+
+struct WatchedState {
+    last_playback_state: Option<PlaybackState>,
+    last_position: Option<PlaybackPositionInfo>,
+    last_volume: Option<u16>,
+    last_mute: Option<bool>,
+}
+```
+
+Nouvelles méthodes :
+```rust
+impl MusicRenderer {
+    /// Démarre le thread de surveillance
+    pub fn start_watching(&self) -> Result<(), ControlPointError>;
+    
+    /// Arrête le thread de surveillance
+    pub fn stop_watching(&self);
+    
+    /// Logique d'auto-advance (appelée quand state passe à Stopped)
+    fn handle_playback_stopped(&self);
+}
+```
+
+### ControlPoint
+
+Responsabilités simplifiées :
+- Registry des devices (renderers et servers)
+- Coordination des opérations multi-renderers (transfer_queue)
+- Point d'entrée API pour les couches supérieures
+- Démarrage/arrêt des watchers lors de l'ajout/suppression de renderers
+
+Supprimer :
+- Le polling loop centralisé (`start_polling_loop`)
+- Les snapshots de surveillance (`RendererSnapshot`)
+- La logique d'auto-advance centralisée
+
+### MusicRendererBackend
+
+Enrichir le trait pour supporter différentes stratégies de surveillance :
+```rust
+pub trait BackendWatcher {
+    /// Retourne la stratégie de surveillance pour ce backend
+    fn watch_strategy(&self) -> WatchStrategy;
+}
+
+pub enum WatchStrategy {
+    /// Polling à intervalle fixe (UPnP, LinkPlay, Arylic)
+    Polling { interval_ms: u64 },
+    /// Notifications push (OpenHome, Chromecast)
+    Push,
+    /// Hybride : push avec polling de secours
+    Hybrid { polling_interval_ms: u64 },
+}
+```
+
+## Étapes d'implémentation
+
+### Étape 1 : Préparer MusicRenderer
+
+**Crate** : `pmocontrol`
+
+1. Ajouter `WatchedState` et les champs associés à `MusicRenderer`
+2. Implémenter `start_watching()` et `stop_watching()`
+3. Implémenter la boucle de surveillance interne avec émission d'événements
+4. Implémenter `handle_playback_stopped()` pour l'auto-advance
+
+### Étape 2 : Adapter par backend
+
+**Crate** : `pmocontrol`
+
+1. Définir le trait `BackendWatcher` et `WatchStrategy`
+2. Implémenter pour chaque backend :
+   - `UpnpRenderer` : Polling 500ms
+   - `OpenHomeRenderer` : Push (via subscriptions UPnP) avec fallback polling
+   - `LinkPlayRenderer` : Polling 500ms
+   - `ArylicTcpRenderer` : Polling 500ms
+   - `ChromecastRenderer` : Push avec fallback polling
+   - `HybridUpnpArylic` : Polling 500ms
+
+### Étape 3 : Simplifier ControlPoint
+
+**Crate** : `pmocontrol`
+
+1. Supprimer `start_polling_loop()` et code associé
+2. Supprimer `RendererSnapshot` et la gestion des snapshots
+3. Modifier `push_renderer()` dans Registry pour appeler `start_watching()`
+4. Modifier la gestion offline pour appeler `stop_watching()`
+5. Supprimer la logique d'auto-advance du `handle_renderer_event()`
+
+### Étape 4 : Tests et validation
+
+1. Vérifier que les événements SSE sont toujours émis correctement
+2. Vérifier l'auto-advance pour chaque type de backend
+3. Vérifier le comportement online/offline
+4. Tests de performance avec plusieurs renderers
+
+## Fichiers impactés
+
+| Fichier | Modification |
+|---------|--------------|
+| `pmocontrol/src/music_renderer/musicrenderer.rs` | Ajout état surveillé, thread watcher, auto-advance |
+| `pmocontrol/src/music_renderer/mod.rs` | Ajout trait `BackendWatcher` |
+| `pmocontrol/src/music_renderer/upnp_renderer.rs` | Impl `BackendWatcher` (Polling) |
+| `pmocontrol/src/music_renderer/openhome_renderer.rs` | Impl `BackendWatcher` (Push/Hybrid) |
+| `pmocontrol/src/music_renderer/linkplay_renderer.rs` | Impl `BackendWatcher` (Polling) |
+| `pmocontrol/src/music_renderer/arylic_tcp.rs` | Impl `BackendWatcher` (Polling) |
+| `pmocontrol/src/music_renderer/chromecast_renderer.rs` | Impl `BackendWatcher` (Push/Hybrid) |
+| `pmocontrol/src/control_point.rs` | Suppression polling loop, simplification |
+| `pmocontrol/src/registry.rs` | Appel start/stop watching |
+
+## Notes
+
+- Ce refactoring est significatif mais améliore la maintenabilité à long terme
+- La migration peut être faite de manière incrémentale en gardant temporairement les deux systèmes
+- Les backends OpenHome et Chromecast bénéficieront particulièrement de cette architecture (notifications push natives)

+<p>Une <code>MusicSource</code> est une abstraction qui représente une
+source de contenu musical dans PMOMusic. Elle peut être :</p>
+<ul>
+<li><strong>Dynamique (FIFO)</strong> : Radio Paradise, streaming radio,
+playlists live</li>
+<li><strong>Statique</strong> : Albums Qobuz, bibliothèque locale,
+playlists fixes</li>
+</ul>
+<p>Le trait <code>MusicSource</code> définit une interface unifiée pour
+: - La navigation UPnP ContentDirectory (browse) - La résolution d’URI
+audio (avec cache) - La gestion de playlists FIFO (pour les sources
+dynamiques) - Le suivi des changements (update_id, last_change)</p>

+<h3 id="performance">Performance</h3>
+<ol type="1">
+<li><strong>Cache agressif</strong> : Utilisez
+<code>SourceCacheManager</code> pour tout</li>
+<li><strong>Pagination</strong> : Limitez le nombre d’items retournés
+(max 100)</li>
+<li><strong>Lazy loading</strong> : Ne chargez que ce qui est
+demandé</li>
+<li><strong>Rate limiting</strong> : Respectez les limites API de la
+source</li>
+<li><strong>Arc&lt;&gt;</strong> : Partagez les données coûteuses</li>
+</ol>
+<h3 id="compatibilité-upnp">Compatibilité UPnP</h3>
+<ol type="1">
+<li><strong>Genre obligatoire</strong> : Certains clients (gupnp-av-cp)
+requièrent <code>&lt;upnp:genre&gt;</code></li>
+<li><strong>URLs absolues</strong> : Toujours retourner des URLs
+complètes (pas de chemins relatifs)</li>
+<li><strong>Protocol Info</strong> : Utilisez
+<code>http-get:*:audio/flac:*</code> pour FLAC</li>
+<li><strong>Duration</strong> : Format <code>H:MM:SS</code> (ex:
+<code>0:03:45</code>)</li>
+<li><strong>childCount</strong> : Optionnel mais recommandé pour
+l’UI</li>
+</ol>
+<h3 id="gestion-derreurs">Gestion d’erreurs</h3>

+<li><strong>CacheError</strong> : Erreur de cache</li>
+</ol>
+<h3 id="thread-safety">Thread Safety</h3>
+<ol type="1">
+<li><strong>Arc&lt;RwLock&lt;&gt;&gt;</strong> : Pour l’état mutable
+partagé</li>
+<li><strong>tokio::sync::RwLock</strong> : Pour l’async</li>
+<li><strong>Éviter Rc&lt;&gt;</strong> : Pas thread-safe</li>
+<li><strong>Clone</strong> : Implémentez <code>Clone</code> pour
+<code>Arc&lt;&gt;</code></li>
+</ol>
+<h2 id="conclusion">Conclusion</h2>
+<p>L’implémentation d’une nouvelle <code>MusicSource</code> suit ces
+étapes :</p>
+<ol type="1">
+<li><strong>Définir le schéma d’Object ID</strong> : Hiérarchie claire
+et cohérente</li>
+<li><strong>Implémenter la navigation</strong> : <code>browse()</code>
+pour tous les niveaux</li>
+<li><strong>Résoudre les URIs</strong> : Cache local d’abord, puis
+original</li>
+<li><strong>Gérer le cache</strong> : <code>SourceCacheManager</code> +
+<code>LazyProvider</code></li>
+<li><strong>Adapter les IDs</strong> : Playlist → Schema de la
+source</li>
+<li><strong>Notifier les changements</strong> : <code>update_id</code> +
+callbacks</li>
+</ol>
+<p>Les exemples Radio Paradise et Qobuz couvrent les deux patterns
+principaux : - <strong>Dynamique FIFO</strong> : Radio Paradise -
+<strong>Catalogue lazy</strong> : Qobuz</p>
+<p>En suivant ces patterns, vous obtiendrez une source musicale
+performante, compatible UPnP, et bien intégrée dans l’écosystème
+PMOMusic.</p>

+<p>Le pattern <code>pmoserver_ext</code> permet d’étendre les

+Suppression de la logique de débouncing SSE</h1>
+<p><strong>Date</strong>: 2026-01-12 <strong>Tâche</strong>:
+WeabApp_debouncingSSE.md</p>
+<h2 id="objectif">Objectif</h2>
+<p>Supprimer la logique de débouncing inutile sur le canal SSE de
+l’application web PMOControl, puisque le serveur contrôle déjà le flux
+des événements.</p>
+<h2 id="analyse-préalable">Analyse préalable</h2>
+<p>J’ai identifié trois endroits avec des mécanismes de temporisation
+dans l’application web :</p>
+<h3 id="mediabrowser.vue---débouncing-sse-à-supprimer">1.
+MediaBrowser.vue - Débouncing SSE (À SUPPRIMER ✓)</h3>
+<ul>
+<li><strong>Débouncing</strong>: 200ms après invalidation du cache</li>
+<li><strong>Cooldown</strong>: 2 secondes entre les rechargements</li>
+<li><strong>Justification originale</strong>: “dédupliquer les
+événements SSE dans le même batch (polling 500ms)”</li>
+<li><strong>Problème</strong>: Cette logique est redondante puisque le
+serveur contrôle déjà le flux SSE</li>
+</ul>
+<h3 id="userenderers.ts---smart-fetching-à-conserver">2. useRenderers.ts
+- Smart fetching (À CONSERVER ✓)</h3>
+<ul>
+<li><strong>Mécanisme</strong>: Comparaison des timestamps
+<code>lastEventAt</code> vs <code>lastSnapshotAt</code></li>
+<li><strong>But</strong>: Éviter de refetch un snapshot déjà à jour</li>
+<li><strong>Justification</strong>: Ce n’est PAS du débouncing, c’est
+une optimisation intelligente qui évite des appels API inutiles</li>
+</ul>
+<h3 id="volumecontrol.vue---ui-debouncing-à-conserver">3.
+VolumeControl.vue - UI debouncing (À CONSERVER ✓)</h3>
+<ul>
+<li><strong>Débouncing</strong>: 300ms sur les changements de
+volume</li>
+<li><strong>But</strong>: Réduire les appels API pendant que
+l’utilisateur fait glisser le curseur</li>
+<li><strong>Justification</strong>: Débouncing légitime pour l’interface
+utilisateur</li>

+<ul>
+<li><strong>Avant</strong>: Délai de 200ms + cooldown de 2s entre les
+rechargements de cache</li>
+<li><strong>Après</strong>: Rechargement immédiat dès l’invalidation du
+cache</li>
+<li><strong>Impact</strong>: Réactivité améliorée de l’interface, les
+mises à jour apparaissent immédiatement</li>
+</ul>
+<h3 id="réduction-de-complexité">Réduction de complexité</h3>
+<ul>
+<li><strong>3 variables supprimées</strong>:
+<code>refreshTimeoutId</code>, <code>lastRefreshTime</code>,
+<code>REFRESH_COOLDOWN_MS</code></li>
+<li><strong>Logique simplifiée</strong>: De ~40 lignes à ~10 lignes dans
+le watcher</li>
+<li><strong>Code plus lisible</strong>: Intention claire sans mécanismes
+de temporisation complexes</li>
+</ul>
+<h3 id="tests">Tests</h3>
+<ul>
+<li>✓ Le projet compile sans erreurs TypeScript</li>
+<li>✓ Le flag <code>isRefreshing</code> empêche toujours les
+rechargements concurrents</li>
+<li>✓ Les autres composants (useRenderers.ts, VolumeControl.vue)
+conservent leurs optimisations légitimes</li>
+</ul>
+<h2 id="conclusion">Conclusion</h2>
+<p>La suppression du débouncing et du cooldown dans MediaBrowser.vue
+simplifie le code tout en améliorant la réactivité de l’interface.
+Puisque le serveur contrôle déjà le flux SSE, ces mécanismes côté client
+étaient redondants et ajoutaient une latence artificielle.</p>
+<p>Le code est maintenant plus simple, plus réactif, et fait confiance
+au serveur pour contrôler la fréquence des événements SSE.</p>

+<h2 id="résumé">Résumé</h2>
+<p>Implémentation réussie de la fonctionnalité d’items épinglables dans
+la crate PMOcache, permettant de protéger certains items de l’éviction
+automatique par la politique LRU. Cette fonctionnalité inclut également
+un système de TTL (Time To Live) avec une règle métier empêchant qu’un
+item soit à la fois épinglé et avec un TTL.</p>

+Suppression de la logique de débouncing SSE</h1>
+<p><strong>Date</strong>: 2026-01-12 <strong>Tâche</strong>:
+WeabApp_debouncingSSE.md</p>
+<h2 id="objectif">Objectif</h2>
+<p>Supprimer la logique de débouncing inutile sur le canal SSE de
+l’application web PMOControl, puisque le serveur contrôle déjà le flux
+des événements.</p>
+<h2 id="analyse-préalable">Analyse préalable</h2>
+<p>J’ai identifié trois endroits avec des mécanismes de temporisation
+dans l’application web :</p>
+<h3 id="mediabrowser.vue---débouncing-sse-à-supprimer">1.
+MediaBrowser.vue - Débouncing SSE (À SUPPRIMER ✓)</h3>
+<ul>
+<li><strong>Débouncing</strong>: 200ms après invalidation du cache</li>
+<li><strong>Cooldown</strong>: 2 secondes entre les rechargements</li>
+<li><strong>Justification originale</strong>: “dédupliquer les
+événements SSE dans le même batch (polling 500ms)”</li>
+<li><strong>Problème</strong>: Cette logique est redondante puisque le
+serveur contrôle déjà le flux SSE</li>
+</ul>
+<h3 id="userenderers.ts---smart-fetching-à-conserver">2. useRenderers.ts
+- Smart fetching (À CONSERVER ✓)</h3>
+<ul>
+<li><strong>Mécanisme</strong>: Comparaison des timestamps
+<code>lastEventAt</code> vs <code>lastSnapshotAt</code></li>
+<li><strong>But</strong>: Éviter de refetch un snapshot déjà à jour</li>
+<li><strong>Justification</strong>: Ce n’est PAS du débouncing, c’est
+une optimisation intelligente qui évite des appels API inutiles</li>
+</ul>
+<h3 id="volumecontrol.vue---ui-debouncing-à-conserver">3.
+VolumeControl.vue - UI debouncing (À CONSERVER ✓)</h3>
+<ul>
+<li><strong>Débouncing</strong>: 300ms sur les changements de
+volume</li>
+<li><strong>But</strong>: Réduire les appels API pendant que
+l’utilisateur fait glisser le curseur</li>
+<li><strong>Justification</strong>: Débouncing légitime pour l’interface
+utilisateur</li>

+<ul>
+<li><strong>Avant</strong>: Délai de 200ms + cooldown de 2s entre les
+rechargements de cache</li>
+<li><strong>Après</strong>: Rechargement immédiat dès l’invalidation du

+<li><strong>Impact</strong>: Réactivité améliorée de l’interface, les

+<ul>
+<li><strong>3 variables supprimées</strong>:
+<code>refreshTimeoutId</code>, <code>lastRefreshTime</code>,
+<code>REFRESH_COOLDOWN_MS</code></li>
+<li><strong>Logique simplifiée</strong>: De ~40 lignes à ~10 lignes dans
+le watcher</li>
+<li><strong>Code plus lisible</strong>: Intention claire sans mécanismes
+de temporisation complexes</li>
+</ul>
+<h3 id="tests">Tests</h3>
+<ul>
+<li>✓ Le projet compile sans erreurs TypeScript</li>
+<li>✓ Le flag <code>isRefreshing</code> empêche toujours les

+<li>✓ Les autres composants (useRenderers.ts, VolumeControl.vue)
+conservent leurs optimisations légitimes</li>
+</ul>
+<h2 id="conclusion">Conclusion</h2>
+<p>La suppression du débouncing et du cooldown dans MediaBrowser.vue
+simplifie le code tout en améliorant la réactivité de l’interface.
+Puisque le serveur contrôle déjà le flux SSE, ces mécanismes côté client
+étaient redondants et ajoutaient une latence artificielle.</p>
+<p>Le code est maintenant plus simple, plus réactif, et fait confiance
+au serveur pour contrôler la fréquence des événements SSE.</p>

+<p>La crâte PMOcache, implémente un system de cache qui pourrait être
+étendu pour permettre une utilisation plus large. L’idée est de modifier
+les règles de déletion des items. Actuellement le cache a une capacité
+maximale. Et les items ont des TTL, qui peuvent être non définies.
+Lorsque le cash est plein, les plus vieux items en termes d’utilisation
+ou ceux qui ont dépassé leur TTL peuvent être détruits. Je propose de
+rajouter une fonctionnalité qui permet d’épingler certains items pour
+les rendre non destructibles. Ils pourraient aussi sortir du comptage
+général des items pour savoir si le cache est plein.</p>
+<p>Il faudra modifier la structure de la base de données. Ajouter une
+colonne indiquant cette propriété. Mettre une règle métier en disant
+qu’on ne peut pas être à la fois épinglés et avec un TTL.</p>
+<p>On se moque de maintenir la compatibilité avec la base de données
+actuelle, il n’y a pas à prévoir de phase de transition. Nous sommes en
+période de développement.</p>
