 # CHANGELOG — kb-app-demo-desktop

+## `0.5.3-pre.005`
+
+- centralise la résolution et la préparation du Store des profils Devnet dans `demo_devnet_common`, utilisé par Solana Core, SPL et Metadata au lieu de rattacher ce contrat partagé à `demo_execution_solana_core` ;
+- ajoute des traces `frontendDebug` explicites pour les clics et invocations de chargement des journaux SPL Token/ATA ainsi que pour la préparation des profils SPL/Metadata, afin de distinguer la réutilisation normale du Store partagé d’une absence de requête ;
+- corrige la préparation automatique des profils Execution Devnet afin qu’elle utilise elle aussi le `ks_store::Store` partagé par profil : l’ouverture d’une seconde fenêtre Devnet et le premier chargement de journal ne rouvrent plus un pool PostgreSQL ni ne relancent `schema_initialize` après que le profil a déjà été préparé ;
+- réutilise désormais un `ks_store::Store` partagé par profil pour toutes les surfaces Execution Devnet : les lectures de journaux et exécutions successives ne recréent plus un pool PostgreSQL ni ne relancent `schema_initialize` à chaque commande, tout en conservant le Store du profil actif séparé des profils Devnet ;
+- corrige la restauration des boutons de navigation Store après le chargement initial parallèle de Replay Candidates : chaque contrôleur déjà chargé retrouve son état `Premier/Précédent/Suivant` une fois toutes les opérations concurrentes terminées, sans exiger un second clic sur `Charger` ;
+- supprime les champs éditables de limite des listings de consultation Store : cinq listes Replay Candidates, annotations de transactions, journal SPL Token et journal ATA ; la taille backend est fixée à 500 lignes par bloc ;
+- ajoute une navigation Store supérieure `Premier bloc / Bloc précédent / Bloc suivant` indépendante de la pagination locale DataTables ;
+- recalcule `totalRows` et `totalBlocks` à chaque chargement ou navigation ; tout bouton `Charger` repart du bloc 1 avec les filtres courants, tandis que `Premier/Précédent/Suivant` rafraîchissent également le nombre de blocs ;
+- invalide les curseurs mémorisés dès qu’un filtre serveur change et exige alors un nouveau chargement du premier bloc ;
+- étend DataTables jusqu’à 500 lignes affichables localement dans le bloc courant ;
+- applique le même contrôleur de blocs aux annotations de Decode Replay et aux journaux SPL Token/ATA ; leurs comptages backend utilisent exactement les filtres serveur visibles, y compris les contraintes de payload, sans `OFFSET` ;
+- termine le nettoyage des identifiants frontend `refreshSql*` / `copySql*` au profit de `refreshStore*` / `copyStore*` ;
+- conserve `demo_config` et le splash sur les résumés Store backend-agnostiques déjà introduits, sans noms physiques d’objets PostgreSQL.
+
 ## `0.5.3-pre.004`

 - aligne la limite maximale de la fenêtre technique de candidats replay Store sur la nouvelle borne interactive backend-agnostique de 500 lignes ;

 Les commandes Tauri sont des adaptateurs minces. La logique réutilisable appartient à `ks-pipeline`, `ks-pipeline-demo-scenarios`, `ks-lib`, `ks-store` et `ks-onchain-transport`.

-Depuis `0.5.3-pre.002`, l'application conserve une façade `ks_store::Store` unique dans `AppState`. Les commandes ne construisent plus de `PostgresStore` et les payloads de configuration/diagnostic ne transportent plus de champs PostgreSQL/SQLite concrets. Les anciennes surfaces `demo_sql_*` sont renommées en `demo_store_*` dès `pre.002`; la refonte fonctionnelle finale de leurs tableaux et compteurs reste planifiée en `pre.005`.
+Depuis `0.5.3-pre.002`, l'application conserve une façade `ks_store::Store` unique dans `AppState`. Les commandes ne construisent plus de backend concret et les payloads de configuration/diagnostic ne transportent plus de champs PostgreSQL/SQLite concrets. Depuis `0.5.3-pre.005`, les listings de consultation Store utilisent des blocs fixes de 500 parcourus par curseurs : Replay Candidates, annotations de transactions et journaux SPL Token/ATA partagent le même principe. Chaque chargement recalcule le nombre total de blocs pour les filtres actifs. Lorsqu’une vue utilise DataTables, sa pagination/son tri/son filtre restent strictement locaux au bloc déjà chargé.

 Les campagnes Devnet/Testnet réutilisables appartiennent à `ks-pipeline-demo-scenarios`. Le desktop conserve leurs adaptateurs UI/Tauri, la sélection opérateur, la progression, les payloads TS-RS et la présentation ; `0.5.4` doit retirer les orchestrations réutilisables qui subsistent encore localement.

 # TODO — kb-app-demo-desktop

 ## Évolutions générales

- [ ] `0.5.3` — finaliser en `pre.005` la présentation des surfaces `demo_store_*`, puis aligner `demo_config` et le splash sur les modèles/compteurs du nouveau baseline sans exposer de noms physiques ; le renommage technique est terminé en `pre.002`.
+- [x] `0.5.3-pre.005` — finaliser les listings de consultation Store avec blocs fixes de 500, curseurs stables, total de blocs recalculé à chaque chargement/navigation et pagination DataTables locale lorsqu’elle existe ; Replay Candidates, annotations et journaux SPL Token/ATA suivent le même contrat, tandis que `demo_config` et le splash consomment les résumés génériques/sanitisés sans noms physiques.
 - [ ] `0.5.4` — réduire les panneaux d'exécution à l'adaptation UI/Tauri en déplaçant toute orchestration de campagne encore réutilisable vers `ks-pipeline-demo-scenarios`.
 - [ ] UX — empêcher les doubles déclenchements pendant une préparation, simulation ou soumission active.
 - [ ] Observabilité — afficher explicitement les comptes relus et les projections matérialisées.

 # Utilisation de kb-app-demo-desktop

 - exécution Solana Core ;
 - exécution SPL.

+## Pagination des listings Store
+
+Les listings de consultation Store n’exposent plus de champ `limit` éditable lorsqu’ils utilisent la borne interactive de 500. Le backend charge un bloc fixe de 500 lignes maximum et recalcule `totalRows`/`totalBlocks` à chaque action `Charger`, `Premier bloc`, `Bloc précédent` ou `Bloc suivant`.
+
+Le curseur reste opaque et n’est jamais saisi par l’opérateur. Modifier un filtre serveur invalide les curseurs mémorisés et impose de recharger le premier bloc. Lorsqu’une vue utilise DataTables, sa pagination, son tri et son filtre restent locaux aux lignes du bloc courant et ne modifient jamais la pagination Store.
+
+Cette règle s’applique aux Replay Candidates, aux annotations de transaction et aux journaux SPL Token/ATA. Les limites métier de backfill, de campagne decode/Core ou de requêtes RPC restent indépendantes et peuvent demeurer configurables.
+
 ## Interface Tauri publique

 Les commandes Tauri constituent l’interface applicative frontend/backend. Elles ne sont pas des APIs Rust publiques pour les autres crates.
