 - [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.

+# 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.

Le forecast souple est détaillé jusqu’à `pre.014`, dernière tranche prévue pour README/USAGE/docs/validation, prompt `0.2.7` et build Tauri final. `0.2.6-pre.002` matérialise la crate `ksp-app-wallet-desk` et son shell Tauri splash/main avec Config + Logging bootstrap, ports `1432/1433`, Bootstrap, Font Awesome, DataTables/Select, SimpleBar, `resize-observer-polyfill`, TS-RS et bridge frontend Logging ; `0.2.6-pre.003` ajoute `cfg.std.wallet`/`schema.std.wallet`, le composite concret Wallet Desk, les adapters Config capables de préserver une sélection composite, les profils Wallet `default`/`temporary`/`tests` et la préparation automatique du répertoire global/effectif par l’application. L’inventory `.kspwallet` reste réservé à `pre.004`.

+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`.
