Subject: [PATCH 1/9] fix(api): avoid NRE in MailSender on rdv query
 notifications

The API did not bind the Smtp section and its appsettings lacked
Site.Owner, so MailSender threw a NullReferenceException and
PostQuery returned 500. Bind Smtp in the API, add Owner/Smtp to the
api appsettings template, and log/skip sending when mail
configuration is incomplete.

 ## Limitations
 
-* **Aujourd'hui** : une prestation par commande, sur un axe client → prestataire unique, sans sous-traitance. **Cible roadmap** : montages multi-parties (plusieurs clients et/ou plusieurs fournisseurs collaborant autour d'un même projet, avec sous-traitance validée par le client) — voir la [ROADMAP](../ROADMAP.md).
 * **Annulation : partielle et non testée.** Côté client, `HairCutCommandController.ClientCancel` / `ClientCancelConfirm` supprime la commande **sans déclencher de refund PayPal** ni logique arrhes vs avance ; aucune action d'annulation côté prestataire. La description du README (arrhes +20%, avance non-annulable) **n'est pas implémentée**. Cible : câbler `RefundTransaction` et le workflow complet, voir [ROADMAP](../ROADMAP.md).
 * **Réclamation post-prestation : aucun support applicatif.** Passée la date de la prestation, le client n'a aucun chemin dans l'UI pour signaler un litige — aucune route, aucun contrôleur, aucun modèle. La fonctionnalité de conciliation est planifiée au **Jalon 5** (cf. [doc/ddd-exploration-2026-06-14.md](../doc/ddd-exploration-2026-06-14.md)) : double vue client/prestataire, dossier de conciliation, décision. En attendant, tout passe par e-mail au propriétaire de l'installation.
 * **Paiement : PayPal uniquement, via l'API NVP/SOAP.** Aucun autre PSP n'est intégré (pas de Stripe, pas d'Adyen). L'API NVP/SOAP que PayPal a dépréciée au profit de REST reste fonctionnelle mais n'est plus recommandée par PayPal ; aucune migration n'est planifiée à court terme.
-* **Périmètre métier étroit.** Pas de saisie de structures de projets complexes ; pas de ticketing associé à la prestation.
 * **Collecte centralisée.** Tous les paiements PayPal transitent par le compte du propriétaire de l'installation — c'est le seul identifiant configuré côté PSP. Les professionnels apparaissent comme tierces parties du point de vue PayPal.
 * **Pas de gestion de paie.** Aucune édition de fiche de paye, ni paiement en masse. Seuls les paiements unitaires sus-cités sont supportés.

+### Reseau de versionnement / git flow pour le CHANGELOG
+
+Regle obligatoire:
+- La section courante du CHANGELOG représente la prochaine version a publier, pas un tag deja créé.
+- Un tag deja publie bloque définitivement la section correspondante du CHANGELOG.
+- Au commit suivant, si la modification impacte le CHANGELOG, il faut incrémenter la version exposée dans le changelog (version du prochain tag attendu), par exemple: `1.0.8-rc30 -> 1.0.8-rc31`.
+
+Ordre a respecter a chaque commit qui modifie le produit:
+1. Verifier si le dernier tag du CHANGELOG existe deja; si oui, incrémenter la version de la section suivante au lieu de re-écrire la dernière section bloquée.
+2. Ouvrir une nouvelle section du CHANGELOG avec ce numero de version incrémenté.
+3. Apres seulement, alimenter cette section avec la description du changement.
+
+En pratique: la version du CHANGELOG est la version "future" a tagger, et elle est incrémentée avant l'écriture de la description; le tag n'est pas créé avant la section, il est seulement établi ensuite lors de la publication effective.
+
 ## Check-list de validation
 
 - Le changement indique son impact architecture.

+# Notifications Yavsc : serveur, Web et PostIt
+
+Ce document décrit les mécanismes de notification actuellement présents
+dans le dépôt. Le terme « notification » recouvre plusieurs flux distincts :
+
+1. les **annonces persistées** en base, affichées dans le site Web et sur
+   l'accueil de PostIt ;
+2. les **messages temporaires de l'interface Web**, attachés à une réponse
+   MVC par `ViewBag.Notify` ;
+3. les **événements temps réel** du chat et les événements métier diffusés par
+   SignalR.
+
+Ces flux n'ont ni le même stockage, ni le même cycle de vie, ni les mêmes
+clients.
+
+## Vue d'ensemble
+
+| Flux | Serveur / transport | Web | PostIt |
+|---|---|---|---|
+| Annonce persistée | Entité `Notification` en base, API HTTP | Affichée dans le layout et masquable | Liste sur `HomePage`, chargée par HTTP et masquable |
+| Message d'interface | Liste de portée requête dans `ViewBag.Notify` | Affichée comme alerte dans le layout | Non consommé |
+| Événement de chat | Hub SignalR authentifié à `/chathub` | Le site Web n'en consomme pas dans ses vues MVC | `notifyUser` et `notifyRoom` alimentent les journaux du chat |
+| Événement métier `push` | SignalR vers les connexions actives, plus e-mail | Pas de consommateur identifié dans les vues Web | Pas de gestionnaire `push` dans le client PostIt actuel |
+
+Les notifications persistées sont donc différentes d'une notification système
+native (notification du navigateur ou du système d'exploitation). Le client
+PostIt affiche une liste dans sa page d'accueil ; il ne demande pas de
+permission de notification native.
+
+## 1. Annonces persistées
+
+### Modèle et stockage
+
+L'entité partagée [`Notification`](../../src/Yavsc.Abstract/Messaging/Notification.cs)
+est enregistrée dans la table `Notification` via `ApplicationDbContext`.
+Elle contient :
+
+- `Id`, identifiant généré ;
+- `title` et `body`, obligatoires, limités respectivement à 1 024 et 512
+  caractères ;
+- `icon`, `sound`, `tag`, `color`, propriétés optionnelles ;
+- `click_action`, obligatoire, utilisé comme libellé d'action dans les
+  interfaces ;
+- `Target`, chaîne de ciblage. Les valeurs documentées par le modèle sont
+  `null` (tout le monde), `user/{UserId}`, `pub/{topic}` et
+  `administration`.
+
+Le masquage d'une annonce pour un utilisateur connecté est stocké dans
+`DismissClicked`, avec une clé composée de l'identifiant utilisateur et de
+l'identifiant de notification. Le même avis peut ainsi être masqué
+indépendamment par chaque utilisateur.
+
+### API
+
+[`NotificationsApiController`](../../src/Yavsc.Api/Controllers/Administration/NotificationsApiController.cs)
+expose les deux routes GET suivantes, sous le préfixe `/api/v1` :
+
+| Route | Accès | Résultat |
+|---|---|---|
+| `GET /api/v1/notifications` | Anonyme ou authentifié | Notifications visibles à l'appelant, non masquées |
+| `GET /api/v1/notifications/me` | Anonyme ou authentifié | Même action et mêmes règles que la route sans suffixe |
+
+La réponse est une liste JSON triée par `Id` décroissant. L'API exclut les
+notifications masquées par l'utilisateur authentifié, puis applique les
+règles d'audience : cible vide, cible `pub/…`, cible correspondant à
+`user/{identifiant courant}`, ou cible `administration` pour un administrateur.
+Une requête anonyme n'a ni identifiant utilisateur ni rôle administrateur.
+
+[`DismissClicksApiController`](../../src/Yavsc.Api/Controllers/Administration/DismissClicksApiController.cs)
+est réservé aux utilisateurs authentifiés :
+
+| Route | Effet |
+|---|---|
+| `GET /api/v1/dismiss` | Liste les identifiants masqués par l'utilisateur |
+| `POST /api/v1/dismiss/click/{notificationId}` | Masque l'avis pour l'utilisateur ; l'opération est idempotente |
+| `DELETE /api/v1/dismiss/click/{notificationId}` | Rétablit l'avis s'il était masqué ; renvoie `404` sinon |
+
+Le POST renvoie `404` si l'identifiant de notification n'existe pas. Le modèle
+de réponse est [`DismissedNotification`](../../src/Yavsc.Abstract/Messaging/DismissedNotification.cs).
+
+### Création et notifications métier
+
+Le contrôleur MVC
+[`NotificationsController`](../../src/Yavsc.Org/Controllers/Communicating/NotificationsController.cs)
+permet la gestion CRUD des enregistrements de notification.
+
+Le service [`YavscMessageSender`](../../src/Yavsc.Server/Services/YavscMessageSender.cs)
+crée aussi une notification persistée, ciblée sur `user/{id}`, pour les
+événements `RdvQueryEvent` et `ClientEstimateSignedEvent`. L'enregistrement
+est effectué avant l'envoi d'e-mail. Le même service tente ensuite d'envoyer
+un e-mail si l'adresse est disponible et confirmée, puis diffuse l'événement
+`push` aux connexions SignalR actives de l'utilisateur.
+
+Cette diffusion `push` est conditionnée par la présence de connexions actives ;
+l'avis stocké en base reste, lui, disponible lors d'une récupération ultérieure
+par l'API.
+
+## 2. Site Web
+
+### Annonces persistées sur l'accueil
+
+[`HomeController.Index`](../../src/Yavsc.Org/Controllers/HomeController.cs)
+charge les notifications non masquées et les place dans `ViewBag.Notify`.
+[`_Layout.cshtml`](../../src/Yavsc.Org/Views/Shared/_Layout.cshtml) les rend
+comme des alertes Bootstrap avec icône, titre, corps et action. Le titre et le
+corps passent par les composants Markdown du site.
+
+Le clic sur l'action appelle `POST /Home/DismissNotification/{id}` via
+[`site.js`](../../src/Yavsc.Org/wwwroot/js/site.js) :
+
+- pour un utilisateur connecté, le masquage est enregistré dans
+  `DismissClicked` ;
+- pour un visiteur anonyme, les identifiants sont conservés dans la session
+  Web (`clicked`).
+
+La route renvoie `404` si l'avis n'existe pas et `204` après le masquage.
+Comme l'API, l'accueil Web filtre `Target` : les cibles `user/{id}` ne sont
+visibles qu'à l'utilisateur correspondant, et la cible `administration`
+uniquement aux administrateurs. Un visiteur anonyme ne reçoit que les
+notifications publiques (`Target` vide ou préfixe `pub/`).
+
+### Messages temporaires par requête
+
+Les helpers [`NotifyInfo`, `NotifyWarning` et `Notify`](../../src/Yavsc.Org/Helpers/ControllerHelpers.cs)
+ajoutent des objets à `ViewBag.Notify`. Ce mécanisme n'écrit pas en base :
+il ne vit que dans la réponse MVC qui rend le layout. Les méthodes
+`NotifyInfo` et `NotifyWarning` partagent actuellement le même rendu générique
+`alert-info`.
+
+## 3. PostIt
+
+[`NotificationsApiClient`](../../src/Yavsc.Api.Client/NotificationsApiClient.cs)
+construit les routes à partir de la base d'API de l'hôte métier configuré.
+Il fournit les méthodes de lecture publique et authentifiée, ainsi que les
+opérations de lecture, masquage et restauration.
+
+Sur [`HomePage`](../../src/PostIt/PostIt/Views/Layout/HomePage.axaml),
+[`HomePageViewModel`](../../src/PostIt/PostIt/ViewModels/Layout/HomePageViewModel.cs)
+charge la liste :
+
+- sans session valide, il appelle la route publique
+  `GET /api/v1/notifications` ;
+- avec une session valide, il appelle
+  `GET /api/v1/notifications/me` avec le client HTTP authentifié.
+
+Le chargement est lancé à l'ouverture de la page et relancé lorsque l'état de
+connexion change. Un compteur de version ignore les réponses obsolètes si un
+chargement plus récent a déjà commencé. L'interface distingue l'état de
+chargement, la liste vide et l'erreur de chargement ; l'utilisateur peut aussi
+actualiser manuellement.
+
+Le bouton d'une notification utilise `click_action` comme libellé et masque
+l'élément. En session authentifiée, PostIt appelle
+`POST /api/v1/dismiss/click/{id}` avant de retirer l'élément de la liste. Si
+l'appel échoue, l'élément reste affiché et une erreur est présentée. Sans
+session, l'élément est retiré de la liste locale, sans persistance du
+masquage côté serveur.
+
+## 4. Événements temps réel
+
+### Hub du chat
+
+Le hub [`ChatHub`](../../src/Yavsc.Server/Hubs/ChatHub.cs) est publié par
+Yavsc.Api à la racine sous `/chathub` (et non sous `/api/v1`) et porte
+`[Authorize]`. Il s'appuie sur SignalR et sur `IConnexionManager` pour suivre
+les utilisateurs et les salons.
+
+Les événements de notification émis par le hub comprennent notamment :
+
+| Événement SignalR | Données | Utilisation PostIt |
+|---|---|---|
+| `notifyUser` | `type`, identifiant ou nom cible, message | Ajout au journal système |
+| `notifyRoom` | `type`, salon, utilisateur ou détail | Ajout au journal du salon ; met à jour la liste d'utilisateurs sur `UserJoin` |
+| `joint` | `ChatRoomInfo` | Initialise la vue du salon rejoint |
+| `ReceiveMessage` | message avec nom, salon et corps | Ajoute le message à l'historique du salon |
+| `notifyUserInRoom` | `type`, salon, message | Pas de gestionnaire correspondant dans `ChatViewModel` actuellement |
+
+Les constantes de types du chat sont déclarées dans
+[`NotificationTypes`](../../src/Yavsc.Abstract/Messaging/NotificationTypes.cs).
+Les messages `notifyUser` et `notifyRoom` ne sont pas enregistrés en base :
+ils décrivent l'état temps réel de connexion, de salon ou les erreurs de
+conversation.
+
+Le [`ChatViewModel`](../../src/PostIt/PostIt/ViewModels/Chat/ChatViewModel.cs)
+ouvre le hub avec le jeton d'accès PostIt, tente un renouvellement silencieux
+du jeton, et active la reconnexion automatique. Après reconnexion, il rejoint
+à nouveau le salon sélectionné, car la connexion SignalR précédente et ses
+groupes ne sont plus actifs. Les callbacks mettent à jour les collections sur
+le thread UI d'Avalonia.
+
+### Événement métier `push`
+
+En plus des événements du chat, `YavscMessageSender` utilise le même contexte
+SignalR pour émettre `push` avec le topic et une charge utile sérialisée. Ce
+nom d'événement est distinct de `notifyUser` et `notifyRoom`. Aucun
+gestionnaire `push` n'est présent dans le client PostIt actuel : les annonces
+métier persistées sont visibles dans PostIt lors du prochain chargement ou
+rafraîchissement HTTP.
+
+## 5. Points d'attention pour les évolutions
+
+- Conserver les règles d'audience alignées entre l'API et le site Web ; en
+  particulier, appliquer un filtrage `Target` côté Web avant d'exposer les
+  avis dans le layout.
+- Ne pas confondre masquage utilisateur (`DismissClicked`) et suppression
+  globale de la notification : le masquage API est par utilisateur.
+- Les sessions anonymes du site Web et PostIt n'ont pas le même comportement :
+  le site Web conserve le masquage en session, tandis que PostIt ne le garde
+  que dans la liste affichée jusqu'au prochain rechargement.
+- Ajouter un nouveau type de cible ou un nouvel événement temps réel implique
+  d'examiner séparément son filtrage, son transport et les clients qui
+  l'écoutent.
+- Les références à GCM et le nom historique de `YavscMessageSender` ne
+  signifient pas que PostIt reçoit une notification native hors ligne : le
+  chemin observé ici est l'e-mail, l'événement SignalR temps réel et la
+  notification persistée récupérée par HTTP.
+

Subject: [PATCH 9/9] fix(android): correct camera frame rotation and recorder
 timestamps

Rotate camera frames before encoding while accounting for Camera2 texture transforms. Align camera timestamps with MediaRecorder and cover capture duration, tracks and rotation with regression tests. Include LibVLC ProGuard rules and update documentation and changelog.

+
+### Added
+
+### Changed
+
+### Fixed
+
+* [PostIt.Android] Avoid applying camera sensor rotation twice: account for the rotation already included in Camera2's SurfaceTexture matrix before rotating encoder input, while retaining portrait output dimensions.
+* [PostIt.Android] Fix zero-second camera captures after adding OpenGL rotation: align Camera2 timestamps with the recorder's monotonic clock, preserve frame intervals, ignore duplicate frames and start camera requests only after the encoder is ready. Add a real Camera2/microphone regression check for segment duration and H.264/AAC tracks.
+* [PostIt.Android] Keep the `VideoLAN.LibVLC.Android` JNI/native bindings alive in Release builds with a ProGuard rule set so the bundled `libvlc`/`libc++_shared` libraries are not stripped.
+* [PostIt.Android] Rotate camera frames before H.264 encoding using an OpenGL surface, based on sensor orientation, lens facing and display rotation at capture start. Portrait captures swap the encoded dimensions; live MPEG-TS/HLS and replays no longer depend on an ineffective MP4-only orientation hint. Restore compilation by reading display orientation from the activity rather than the capture service.

+Ce test detecte notamment les captures de zero seconde dues au decalage entre
+l'horloge Camera2 et celle de MediaRecorder. Les fichiers restent dans le
+repertoire prive indique par le resultat pour verification locale.
+Le resultat inclut les angles capteur/ecran et la premiere matrice
+SurfaceTexture recue. Les tests unitaires couvrent notamment la matrice
+reelle `[0,-1,0,0,-1,0,0,0,0,0,1,0,1,1,0,1]` : pour un capteur a 90 degres
+et un ecran a 0, elle porte deja la rotation et ne doit pas recevoir 90 degres
