 # Changelog

+## [1.0.8-rc14] - unstable
+
+### Added
+
+* [PostIt] Ajout d'un `BillingQueryDetailsPageViewModel` et de sa page associee pour afficher le detail d'une commande billing depuis l'historique.
+* [PostIt] Ajout d'un mode detail avec section metier (statut, date, description, motif, infos) et section technique repliable (code, client, provision, lieu, prestations).
+* [PostIt] Ajout d'un badge de statut enrichi (couleur + pictogramme) sur le detail d'une commande pour visualiser l'etat en un coup d'oeil.
+* [PostIt] Ajout d'un bloc d'actions rapide en tete du detail (`Retour`, `Ouvrir en edition`) pour eviter le scroll jusqu'au bas de page.
+* [PostIt] Ajout d'un style monospace sur les metadonnees techniques (code billing, client, provision, lieu, prestations) pour faciliter la lecture des identifiants et valeurs brutes.
+
+### Changed
+
+* [PostIt] Le bouton d'ouverture depuis la liste billing ouvre maintenant une page de detail dediee avant l'eventuelle edition.
+* [PostIt] Amelioration UX des pages billing: badges de statut colores, actions remontees en haut de page, et typographie monospace sur les metadonnees techniques.
+
+### Fixed
+
+* [Yavsc.Api] Correction d'un 500 sur le refresh du catalogue d'activites lorsque `Activity.Description` est `NULL` en base (nullabilite explicite + projection null-safe + gardes sur codes vides).
+* [Yavsc.Api] Correction des erreurs 400/500 sur les routes billing (`Rdv`, `Brush`, `MBrush`) en imposant `ClientId` depuis l'utilisateur authentifie et en ignorant les champs server-owned lors de la validation modele.
+* [Yavsc.Api] Correction du `PUT /api/v1/billing/Rdv/{id}`: mise a jour controlee de l'entite existante (et non remplacement brut du graphe JSON), ce qui supprime les `BadRequest` parasites.
+* [Yavsc.Api] Correction PostgreSQL `timestamptz` sur RDV: normalisation UTC de `EventDate` sur `POST/PUT /api/v1/billing/Rdv` pour eviter l'erreur `Cannot write DateTime with Kind=Local`.
+* [Yavsc.Api] Correction du flux FrontOffice accept/reject de query: sauvegarde avec contexte utilisateur et fallback d'injection pour `IBillingService` afin d'eviter les erreurs serveur en environnement de test.
+* [Yavsc.Blogs] Correction des `BadRequest` sur `POST/PUT /api/v1/blogspot` avec payload JSON (PostIt): les proprietes de navigation/serveur (`Author`, `Tags`, `Comments`, audit) ne bloquent plus la validation.
+* [Yavsc.Org] Correction du flux MVC de creation de commentaire: `SaveChangesAsync(userId)` est utilise pour renseigner les champs d'audit requis (`UserCreated`/`UserModified`).
+* [Yavsc.Api.Test] Stabilisation des fixtures de seed billing: remplissage des metadonnees d'audit (`UserCreated`, `UserModified`, dates) pour eviter les echecs SQLite `NOT NULL`.
+
+## [1.0.8-rc13] - unstable
+
+### Added
+
+* [PostIt] Integration d'un selecteur de lieu RDV base sur Mapsui (carte interactive dans le formulaire `Rdv`).
+* [PostIt] Ajout d'un marqueur de position et d'une action de recentrage sur la carte RDV.
+* [PostIt] Ajout d'un service de reverse geocoding pour suggerer une adresse a partir des coordonnees carte.
+* [PostIt] Cache et debounce des resolutions d'adresse RDV pour limiter les appels reseau et lisser l'UX.
+* [PostIt.Tests] Nouvelles non-regressions sur le panneau d'adresse suggeree RDV et le comportement de la carte.
+* [Yavsc.Abstract] Activation de `#nullable enable annotations` sur les fichiers legacy avec annotations nullable.
+* [Yavsc.Server] Activation de `#nullable enable annotations` sur les fichiers legacy avec annotations nullable.
+
+### Changed
+
+* [PostIt] Generalisation de la barre de statut d'action (severite explicite) sur pages principales, dialogues et formulaires billing.
+* [PostIt] Harmonisation des messages de statut utilisateur en francais.
+* [PostIt] Renforcement des gardes de navigation dans les flux de gestion des membres de cercle.
+* [PostIt] Le flux RDV conserve l'adresse saisie manuellement et propose l'adresse resolue comme suggestion explicite.
+* [PostIt] Le flux de geolocalisation RDV tolere les positions proches dans le cache de suggestion d'adresse.
+
+### Fixed
+
+* [PostIt.Desktop] Correction d'un crash au demarrage OIDC (`No authority specified`) via durcissement des valeurs par defaut de configuration d'authentification.
+* [PostIt] Correction de la persistance des settings: l'etat runtime de statut n'est plus serialize dans le JSON utilisateur.
+* [PostIt.Tests] Ajout d'un verrou de non-regression sur le premier chargement des settings.
+* [PostIt] Correction du binding de la date RDV: `DatePicker.SelectedDate` est aligne sur un proxy `DateTimeOffset?` (`EventDateSelection`).
+
+## [1.0.8-rc12] - unstable
+
+### Added
+
+* [PostIt] Nouveau helper d'image `ImageHelper` pour charger des bitmaps depuis les ressources et depuis le web.
+* [PostIt] Affichage de l'avatar XS dans la liste des performers d'activites, avec fallback visuel (initiale utilisateur).
+* [PostIt.Tests] Nouveaux tests autour des URLs avatar et de la source d'autorite.
+* [contrib] Ajout d'un `README.md` utilitaire pour les symboles/icones.
+
+### Changed
+
+* [PostIt] Les avatars ne sont plus relies en string sur `Image.Source`: ils sont telecharges et lies en `Bitmap`.
+* [Yavsc.Api.Client] `ActivityApiClient` accepte une base d'avatar dediee et construit les URLs avatar depuis l'autorite d'identification.
+* [PostIt] Les clients Activites/Billing utilisent maintenant `ApiUrl` en lecture dynamique: un changement via Parametres prend effet sans redemarrer l'application (apres sauvegarde et rafraichissement de la page).
+* [PostIt] Le header de `MainPage` n'utilise plus `ScrollViewer`; remplacement par une barre de commandes basee sur `WrapPanel`.
+* [PostIt] Alignement de la navigation blogs: renommage `PushMainPageAsync` -> `PushBlogsPageAsync` et ajustement de `HomePageViewModel`.
+
+### Fixed
+
+* [PostIt.Android] Correction d'un 404 sur la page Activites au premier lancement: la configuration embarquee pointait `ApiUrl` vers le host Blogs au lieu de l'API metier.
+* [PostIt] Correction du bouton Sauver de la page Parametres: binding vers `SaveCommand` pour persister correctement `ApiUrl`/`BlogsApiUrl`.
+
+## [1.0.8-rc11] - unstable
+
+### Added
+
+nothing
+
+### Changed
+
+* [Yavsc.Api.Test] Mise a jour de `Microsoft.EntityFrameworkCore.Sqlite` vers `10.0.11` afin de supprimer l'alerte NU1903 liee a `SQLitePCLRaw.lib.e_sqlite3` 2.1.11.
+* [Yavsc.Org] Nettoyage de la configuration NuGet pour le restore: suppression du fichier local `Directory.Packages.props` au profit du fichier racine centralise.
+* [Yavsc.Org] Suppression de references de packages redondantes dans le projet, sans impact fonctionnel attendu.
+
+### Fixed
+
+* [Yavsc.Api.Test] Le restore n'emet plus le warning de vulnerabilite `NU1903` sur `SQLitePCLRaw.lib.e_sqlite3`.
+* [Yavsc.Org] Suppression d'une vulnerabilite de severite elevee sur AutoMapper apres publication et consommation de la nouvelle version candidate de `HigginsSoft.IdentityServer8`.
+
+## [1.0.8-rc10] - unstable
+
+### Added
+
+* [PostIt] Une page d'historique des commandes billing permet maintenant d'ouvrir une commande existante.
+* [PostIt] Une vue "Demandes en cours" en lecture seule est disponible pour le performer, filtrée sur les statuts actifs (Inserted, Accepted, InProgress).
+* [Yavsc.Org] Nouvelles entités `Country` et `PerformerCodeInputValidation` pour piloter la validation du code entreprise performer par pays.
+
+### Changed
+
+* [PostIt] La page détail billing se préremplit depuis une commande existante (Rdv, Brush, MBrush) et passe en mode mise à jour.
+* [Yavsc.Org] Le formulaire `Manage/SetActivity` inclut désormais le pays d'exercice (`fr`, `en`, `pt`) et applique la regex associée au champ `SIREN`.
+* [Yavsc.Org] La vérification externe du numéro d'entreprise est conservée uniquement pour le pays `fr`.
+
+### Fixed
+
+* [PostIt] Le flux historique n'est plus limité à une simple liste: l'action d'ouverture charge la commande cible puis navigue vers la page détail.
+* [Yavsc.Org] Le champ `SIREN` n'est plus validé avec une règle unique indépendante du pays d'exercice.

+# Playbook d'usage des agents IA (Yavsc)
+
+Ce playbook normalise l'usage de Copilot, Plan et Explore dans le depot.
+Il privilegie des sorties verifiables: fichiers, commandes tests, risques.
+
+## Quand utiliser quel agent
+
+- Plan: quand la tache est ambigue, transverse ou risquee.
+- Explore: quand il faut cartographier rapidement des zones du code.
+- Copilot: quand les specifications sont claires et localisees.
+
+## Prompt type (base)
+
+Utiliser ce squelette avant toute tache non triviale:
+
+```text
+Contexte: <projet/fichier/fonction>
+Objectif: <resultat observable>
+Contraintes: <style, archi, perimetre>
+Verification: <tests exacts a lancer>
+Sortie attendue: <fichiers modifies + risques>
+```
+
+## 4 scenarios de reference
+
+## 1) Explorer un bounded context
+
+Intention:
+- Comprendre ou implementer un changement dans un BC sans regression laterale.
+
+Prompt minimal:
+```text
+Explore le BC <nom> avec profondeur medium.
+Retour: composants touches, points d'entree, tests existants et risques.
+```
+
+Preuves attendues:
+- Carte des fichiers a modifier.
+- Test(s) smoke/mandatory proposes.
+
+## 2) Ajouter un smoke test
+
+Intention:
+- Couvrir rapidement un endpoint ou une route publique.

+Propose un smoke test pour <route/endpoint> dans le projet de test approprie.
+Respecte les conventions de doc/testing.md.
+```
+
+Preuves attendues:
+- Fichier test cree/modifie.
+- Commande precise pour executer le test cible.
+
+## 3) Corriger une regression backend API
+
+Intention:
+- Corriger un bug sans casser un flux voisin.
+
+Prompt minimal:
+```text
+Planifie puis implemente un fix de <symptome> dans <projet>.
+Ajoute/ajuste un test NonRegression rouge puis vert.
+```

+Cartographie le flux OIDC PostIt: entrypoints, callback, stockage token,
+refresh. Donne points de rupture probables et tests/verification proposes.
+```
+
+Preuves attendues:
+- Liste ordonnee des etapes du flux.
+- Fichiers critiques.
+- Hypotheses testables.
+
+## Anti-patterns a eviter
+
+- Prompt sans objectif verifiable.
+- Demande trop large sans perimetre de fichiers.
+- Validation basee uniquement sur "ca semble correct".

+# Onboarding guide: agents IA + architecture + tests
+
+Ce guide est optimise pour accelerer la prise en main des agents IA
+(Copilot, Plan, Explore) dans Yavsc, avec une verification rapide
+par les tests.
+
+## Resultat attendu
+
+A la fin du parcours, un contributeur doit pouvoir:
+- Identifier les projets impactes par une modification.
+- Choisir l'agent adapte a l'intention de travail.
+- Produire une proposition de changement verifiable par les tests.
+
+## Parcours en 3 modules
+
+## Module A - Comprendre le terrain (30-45 min)
+
+Objectif: acquerir une lecture fiable de l'architecture.
+
+1. Lire [README.md](../README.md) puis [Architecture.md](Architecture.md).
+2. Lire [architecture/decoupage-organisation.md](architecture/decoupage-organisation.md).
+3. Selon le domaine:
+   - Backend/API: [architecture/workflow-multi-parties.md](architecture/workflow-multi-parties.md)
+   - PostIt: [architecture/postit.md](architecture/postit.md) puis [architecture/postit-oidc.md](architecture/postit-oidc.md)
+
+Definition of done:
+- Expliquer en 5 phrases quelles couches sont touchees.
+- Citer le ou les points d'entree applicatifs a verifier.
+
+## Module B - Boucle tests rapide (20-30 min)
+
+Objectif: verifier rapidement sans lancer toute la suite.
+
+1. Lire [testing.md](testing.md).
+2. Lancer les smoke tests d'abord, puis mandatory selon le projet.
+3. N'elargir au test complet que si le scope depasse le BC touche.
+
+Definition of done:
+- Fournir la commande test executee.
+- Expliquer pourquoi ce niveau de test est suffisant.
+
+## Module C - Usage agentique en production (30-40 min)
+
+Objectif: utiliser les agents comme accelerateurs, pas comme boites noires.
+
+1. Plan: decomposer la tache en etapes verifiables.
+2. Explore: collecter le contexte code/doc precise.
+3. Copilot: implementer localement et verifier.
+
+Regles:
+- Toujours donner un contexte explicite (fichier, but, contrainte).
+- Demander des preuves observables (fichiers modifies, tests, risques).
+- Refuser toute sortie non verifiable.
+
+Definition of done:
+- Une tache simple est livree avec:
+  - Plan
+  - Changement local
+  - Preuve par test
+
+## Routine continue (sans echeance fixe)
+
+Rituels recommandes:
+- Hebdo: revue des prompts qui ont bien fonctionne.
+- Mensuel: mise a jour du present guide et du playbook.
+- A chaque incident: ajouter un anti-pattern dans le playbook.
+
+## Check-list de validation
+
+- Le changement indique son impact architecture.
+- Le choix de l'agent est justifie.
+- La preuve test est incluse.
+- Les risques residuels sont explicitement listes.

Paul Schneider	b2fcd165f7	test(oidc): cover discovery regression and consume fixed IdentityServer8 rc007 Add an application-level smoke test for /.well-known/openid-configuration and a direct IResourceStore check so the IdentityServer8 mapper failure is caught from the Yavsc side. Bump HigginsSoft.IdentityServer8 packages to 8.1.0-pazofrc007, which includes the EntityFramework mapper fix removing the failing AutoMapper static initialization. This closes the 500 on OIDC discovery and restores remoting/auth flows that depend on discovery metadata.	2026-08-31 17:35:02 +01:00
