 - [X] `0.2.3` — HTTP Transactions stable : 11/11 wrappers typés publiés, classification `8 Read / 2 WriteSubmission / 1 Simulation`, no-resend ambigu prouvé pour les write submissions, `KSP-TRANSPORT-007` réaudité conforme sur les 37 wrappers HTTP courants, graphes Cargo et deux smokes Devnet validés ; `0.2.4` reprend les 15 Blocks/Economics restants.
 - [X] `0.2.4` — HTTP Blocks + Economics stable : 15/15 wrappers `V0_2_4` publiés, surface typed complète à 52/52 méthodes courantes, 14/14 historiques conservées, réaudit SIMD/inventaire final et `KSP-TRANSPORT-007` global validés ; deux smokes Devnet passés avant publication.
 - [X] `0.2.5` — Wallet foundation stable : `.kspwallet` V1, VIEW/OWNER indépendants, Argon2id/XChaCha20-Poly1305, autorité Ed25519 OWNER, persistence no-clobber, signature, administration/rotations/révocation VIEW forte, import/export Solana CLI JSON + Base58, canaris adversariaux, interop externe et documentation durable publiés. La clôture `pre.010-fix.001`–`fix.003` ajoute `ed25519-dalek 3.0.0` direct, normalise le Rust workspace et installe l’audit structurel Python complémentaire à rustfmt/Clippy. `Pubkey` reste via `ksp-core-lib`, la keypair reste encapsulée dans Wallet et Config/Transport/ExecutionPolicy/Store/Tauri restent hors Wallet.
-- [ ] `0.2.6` — Introduire `ksp-app-wallet-desk` utilisant Config composite + Wallet + transport HTTP. `pre.001` fixe le sizing et le gabarit ; `pre.002` matérialise la crate Tauri et son shell splash/main avec Config + Logging bootstrap, ports `1432/1433`, Bootstrap, Font Awesome, DataTables/Select, SimpleBar, resize-observer-polyfill, TS-RS et bridge frontend Logging. Les tranches suivantes ajoutent `cfg.std.wallet`, inventory, lifecycle VIEW/OWNER, secrets `KSP_SECRET_WALLET_PASS_*`, identité autorisée + `getBalance`, puis administration/import/export, avec une dernière tranche prévue pour README/USAGE/docs/validation, prompt `0.2.7` et build Tauri final.

 - [ ] `0.2.7` — Étendre `ksp-onchain-transport-lib` au WebSocket Solana standard complet ; permettre plusieurs sessions sur une même URL sans imposer encore un pool automatique complexe.
 - [ ] `0.2.8` — Ajouter Helius LaserStream WebSocket comme extension du moteur WebSocket standard, sans duplication de client.
 - [ ] `0.2.9` — Ajouter une première fondation Yellowstone gRPC standard/provider-neutral ; dimensionner la surface exacte à `pre.001` selon la documentation normative actuelle.

 `0.2.1-pre.006` introduit le premier nouveau domaine standard depuis Logging : `std.transport.json`, son schema, son exemple, son enregistrement et l'adapter Config -> `HttpTransportSettings`. Cette extension confirme que les nouveaux domaines restent ajoutés à la demande d'un consumer réel, sans transformer Config en propriétaire du runtime Transport.
 
+## Extension `0.2.6` — Wallet Desk

+`0.2.6-pre.003` ajoute le domaine standard Wallet au moment où son premier consumer réel en a besoin : `cfg.std.wallet`, `schema.std.wallet`, `ResolvedWalletConfig` et le composite concret `cfg.composite.ksp-app-wallet-desk`. `wallets_directory` reste global ; `wallets_subdirectory` est optionnel par profil et ne peut pas sortir de la racine par syntaxe de path. L’adapter Config résout les paths et leur provenance mais ne crée pas de répertoire et ne dépend pas de `ksp-wallet-lib`.

+# Delta `0.2.6-pre.003` — `std.wallet`, composite Wallet Desk et répertoires
+
+## Base requise
+
+```text
+0.2.6-pre.002 appliquée
+workspace.package.version = 0.2.6-pre.2
+```
+
+Les preuves opérateur de `pre.002` sont vertes : installation npm initiale, `cargo fmt --all`, audit structurel Python, `cargo check --workspace`, `cargo clippy --workspace --all-targets`, `cargo test -p ksp-app-wallet-desk` et `cargo tauri dev -c crates/ksp-app-wallet-desk/tauri.conf.json`. Le shell Tauri/Vite a démarré sur le port réservé `1432`.
+
+## Type de livraison
+
+```text
+ksp-general-0.2.6-pre.003.zip
+```
+
+Cette tranche modifie Config, le runtime Wallet Desk et les fichiers de configuration exécutables. Elle incrémente donc `workspace.package.version` vers `0.2.6-pre.3`.
+
+## Objet
+
+Matérialiser la composition Config nécessaire à Wallet Desk sans ouvrir encore un fichier `.kspwallet` ni implémenter l'inventory de `pre.004`.
+
+Le delta fournit :
+
+```text
+cfg.std.wallet
+schema.std.wallet
+cfg.composite.ksp-app-wallet-desk
+wallets_directory global
+wallets_subdirectory optionnel par profil
+profils Wallet default / temporary / tests
+ResolvedWalletConfig
+mapping d'un profil déjà résolu par composite vers Logging/Wallet
+préservation ConfigProfileSelectionSource::Composite
+bootstrap Wallet Desk logging + transport + wallet component validation
+création automatique du répertoire global/effectif
+rejet de root non-directory et de symlinks dans le sous-répertoire de profil
+logs debug sur directory ready/created
+logs error sur préparation impossible
+statut runtime/UI Config + chemins Wallet sûrs
+```
+
+## `std.wallet`
+
+Le document standard est enregistré sous :
+
+```text
+file_id = cfg.std.wallet
+schema_file_id = schema.std.wallet
+filename = std.wallet.json
+schema filename = std.wallet.schema.json
+```
+
+Shape runtime :
+
+```json
+{
+  "format_version": 1,
+  "wallets_directory": "${KSP_WALLETS_DIRECTORY:-wallets}",
+  "default_profile": "default",
+  "profiles": [
+    {"profile_id": "default"},
+    {"profile_id": "temporary", "wallets_subdirectory": "temporary"},
+    {"profile_id": "tests", "wallets_subdirectory": "tests"}
+  ]
+}
+```
+
+`wallets_directory` est global. `wallets_subdirectory` reste relatif, optionnel et peut contenir plusieurs composants normaux. Chemin absolu, `.` ou `..` sont rejetés. Les valeurs de sensibilité `Secret` sont refusées par l'adapter Wallet : un password ne peut donc pas être injecté comme path Config.
+
+`ksp-config-lib` résout et valide les paths mais ne crée aucun répertoire et n'énumère aucun wallet.
+
+## Composite Wallet Desk
+
+Le premier composite runtime concret est :
+
+```text
+file_id = cfg.composite.ksp-app-wallet-desk
+filename = composite.ksp-app-wallet-desk.json
+schema = schema.composite
+```
+
+Le profil autonome `devnet` sélectionne :
+
+```text
+logging   -> cfg.std.logging   / local_dev
+transport -> cfg.std.transport / devnet_public
+wallet    -> cfg.std.wallet    / default
+```
+
+Les profils composites `temporary` et `tests` réutilisent Logging/Transport mais sélectionnent respectivement les profils Wallet `temporary` et `tests`.
+
+Wallet Desk exige les trois `component_id` et vérifie leurs `file_id` attendus avant de poursuivre son bootstrap. Le pool Transport n'est pas encore construit dans cette tranche ; cette composition est validée maintenant pour ne pas inventer une sélection parallèle plus tard.
+
+## Adapters Config
+
+`ResolvedWalletConfig` expose :
+
+```text
+file_id
+source_path
+profile_id
+selection_source
+effective Config sûr/réel selon contrat Config
+wallets_directory
+wallets_subdirectory
+effective_wallets_directory
+```
+
+Deux entrées complètent les adapters pour un profil déjà sélectionné par composite :
+
+```text
+ConfigDocumentEngine::resolve_logging_config_profile
+ConfigDocumentEngine::resolve_wallet_config_profile
+```
+
+Elles évitent de recharger le même profil comme sélection `Explicit` et conservent `ConfigProfileSelectionSource::Composite`.
+
+Cette extension ne crée aucune dépendance Config -> `ksp-wallet-lib`.
+
+## Répertoires Wallet
+
+Après initialisation du Logging, Wallet Desk résout le composant Wallet et prépare la filesystem surface applicative :
+
+```text
+wallets_directory
+-> création si absent
+-> optional wallets_subdirectory composant par composant
+-> effective_wallets_directory prêt
+```
+
+Politique de cette tranche :
+
+```text
+root déjà directory          -> accepté
+root absent                  -> create_dir_all
+root existant non-directory  -> wallet_desk.wallet_directory_invalid
+profile component absent     -> create_dir
+profile component directory  -> accepté
+profile component symlink    -> wallet_desk.wallet_directory_invalid
+profile component fichier    -> wallet_desk.wallet_directory_invalid
+inspection/création I/O KO   -> wallet_desk.wallet_directory_prepare_failed
+```
+
+Un succès/prêt est journalisé en `debug`. Une impossibilité de préparation est journalisée en `error` puis surfacée au bootstrap. Les paths sont non secrets par contrat `std.wallet`.
+
+L'inventory `.kspwallet`, la canonicalisation des fichiers candidats et la policy complète de sélection de fichiers restent `pre.004`.
+
+## Environnement
+
+`/.env.example` documente désormais :
+
+```text
+KSP_WALLETS_DIRECTORY=wallets
+# KSP_SECRET_WALLET_PASS_01=
+```
+
+La seconde ligne documente uniquement le pattern prévu pour la future tranche d'unlock. Aucun provider de password n'est implémenté dans `pre.003` et aucune valeur `KSP_SECRET_WALLET_PASS_*` n'est lue par Wallet Desk à ce stade.
+
+## UI/runtime status
+
+Le DTO `RuntimeStatusDto` et le Dashboard affichent maintenant :
+
+```text
+version / phase
+nombre de ressources Config enregistrées
+profil composite
+profil Logging
+profil Wallet
+fallback Logging
+wallets_directory
+wallets_subdirectory
+répertoire Wallet effectif
+création du répertoire effectif au démarrage oui/non
+```
+
+Aucune Pubkey, aucun alias interne Wallet, aucune note et aucun secret ne sont ajoutés à cette projection.
+
+## Tests ajoutés/étendus
+
+Config :
+
+```text
+registre à 8 descripteurs
+cfg.std.wallet + schema + composite enregistrés
+schema std.wallet
+root global sans subdirectory
+profil tests -> subdirectory relatif
+precedence process > .env pour KSP_WALLETS_DIRECTORY
+rejet absolute / parent / current subdirectories
+rejet d'un path Wallet de sensibilité Secret
+profil Wallet sélectionné par composite conserve provenance Composite
+public API des nouveaux adapters/constants
+ownership des filenames Config-managed
+```
+
+Wallet Desk :
+
+```text
+composite devnet -> logging/local_dev + transport/devnet_public + wallet/default
+création idempotente root + nested profile directory
+rejet root non-directory
+rejet symlink de profile path sur Unix
+statut frontend expose les projections Config prévues
+```
+
+## Dépendances
+
+Aucune dépendance Cargo ou npm n'est ajoutée/modifiée dans cette tranche. `package.json` et `tauri.conf.json` changent uniquement leur version applicative vers `0.2.6-pre.3`.
+
+Il n'y a donc **aucune commande npm directe à exécuter pour `pre.003`**.
+
+## Version technique
+
+```text
+workspace.package.version = 0.2.6-pre.3
+commit = v0.2.6-pre.003
+```
+
+Aucun tag stable.
+
+## Validation opérateur requise
+
+Après application :
+
+```bash
+cargo fmt --all
+python3 scripts/audit_rust_workspace_rules.py
+cargo check --workspace
+cargo clippy --workspace --all-targets
+cargo test -p ksp-config-lib
+cargo test -p ksp-app-wallet-desk
+cargo test --workspace
+KSP_WALLETS_DIRECTORY=var/wallet-desk-pre003 cargo tauri dev -c crates/ksp-app-wallet-desk/tauri.conf.json
+```
+
+Le parcours Tauri doit vérifier que le Dashboard affiche le profil composite `devnet`, le profil Wallet `default`, la racine override `var/wallet-desk-pre003` résolue et le répertoire effectif prêt/créé, avec événement backend `debug` correspondant. Le répertoire `var/` est déjà ignoré par le repository.
+
+`cargo tauri build -c crates/ksp-app-wallet-desk/tauri.conf.json` **n'est pas exécuté en `pre.003`**. Il reste la toute dernière opération de validation de `0.2.6`.
+
+## Suite
+
+`pre.004` branche l'inventory réel : enumeration non récursive `.kspwallet`, policy symlink/path, `inspect_locked_wallet_file_v1`, DTOs locked, DataTables, sélection de ligne et refresh, sans révéler Pubkey/alias/notes.

 Mission : valider Config composite + `.kspwallet` + transport HTTP dans une application Tauri mince.
 
-Le solde d'un wallet constitue un premier cas de validation réseau obligatoire. L'application garde les handles VIEW/OWNER côté Rust, ne persiste aucun password dans Config/frontend et délègue toute crypto/signature/administration à `ksp-wallet-lib`.
+Le solde d'un wallet constitue un premier cas de validation réseau obligatoire. L'application garde les handles VIEW/OWNER côté Rust, ne persiste aucun password dans les documents JSON Config ni dans le frontend et délègue toute crypto/signature/administration à `ksp-wallet-lib`. Des secrets opérateur `KSP_SECRET_WALLET_PASS_*` peuvent être fournis par process env ou `.env`, exclusivement via les APIs Config et sans traverser le frontend.
 
 Le prompt [`../../prompts/011-V0_2_6_START_PROMPT.md`](../../prompts/011-V0_2_6_START_PROMPT.md), préparé par `0.2.5-pre.010`, impose un `pre.001` d'audit/sizing couvrant Config `std.wallet`/composite, inventory/path safety, lifecycle VIEW/OWNER, balance `getBalance`, bridge Tauri/TS-RS, sécurité password/export, logging et validation finale Tauri.
 
-`0.2.6-pre.001` confirme que le registre Config doit être étendu pour `cfg.std.wallet`/`schema.std.wallet` et `cfg.composite.ksp-app-wallet-desk`; `wallets_directory` reste global avec fallback `${KSP_WALLETS_DIRECTORY:-wallets}` tandis qu'un profil `default` minimal préserve le contrat de résolution composite. Le gate retient une inventory non récursive `.kspwallet`, sans symlink, root-scoped, les handles VIEW/OWNER exclusivement côté Rust, une CSP Tauri explicite, `getBalance` via la Pubkey du handle autorisé et les flows OWNER metadata/rotations/revocation/export fichier déjà possédés par Wallet. Le scope tient dans `0.2.6` mais le forecast initial est regranularisé jusqu'à `pre.013`; le plan actif est `docs/plans/013-V0_2_6_WALLET_DESK_PLAN.md`.
+`0.2.6-pre.001` confirme que le registre Config doit être étendu pour `cfg.std.wallet`/`schema.std.wallet` et `cfg.composite.ksp-app-wallet-desk`. `wallets_directory` reste global avec fallback `${KSP_WALLETS_DIRECTORY:-wallets}` et chaque profil peut définir un `wallets_subdirectory` relatif pour isoler tests, temporaires ou futurs scénarios. Wallet Desk prépare/crée le répertoire effectif après résolution Config et journalise le succès en debug ou l'échec en error. Le gabarit Config Desk est réutilisé avec Bootstrap, Font Awesome, DataTables/Select, SimpleBar et `resize-observer-polyfill`. L'inventory reste non récursive `.kspwallet`, sans symlink d'entrée et root-scoped; les handles VIEW/OWNER restent exclusivement côté Rust. L'ouverture accepte un password éphémère saisi ou une tentative explicite de secrets Config `KSP_SECRET_WALLET_PASS_*`, dont ni nom ni valeur ne traversent le frontend. `getBalance` utilise la Pubkey du handle autorisé et les flows OWNER metadata/rotations/revocation/export fichier délèguent à Wallet. La CSP reste `null` par défaut comme dans Config Desk et n'est réauditée qu'en présence d'un besoin WebView concret. Le forecast souple détaillé s'étend jusqu'à `pre.014`, dernière tranche prévue pour README/USAGE/docs/validation, prompt `0.2.7` et build Tauri final; le plan actif est `docs/plans/013-V0_2_6_WALLET_DESK_PLAN.md`.

Aucun inventory ou fichier `.kspwallet` n’est encore ouvert dans cette tranche.

 `0.2.6-pre.002` matérialise ensuite la première tranche technique : la crate `ksp-app-wallet-desk` rejoint le workspace avec le shell splash/main du gabarit Config Desk, le bootstrap Config + Logging commun, les ports `1432/1433`, Bootstrap, Font Awesome, DataTables/Select, SimpleBar, `resize-observer-polyfill`, TS-RS et le bridge frontend -> Rust -> `ksp-logging-lib`.

Wallet Desk valide les composants `logging`/`transport`/`wallet`, crée la racine et le sous-répertoire effectif absents avec logs `debug`, refuse les objets filesystem invalides/symlinks de sous-répertoire avec logs `error`, et expose uniquement les chemins/profils non secrets dans le statut runtime. Aucun inventory `.kspwallet` n’est encore effectué.
