 # Roadmap KSP

@@ -50,7 +50,7 @@ Le roadmap décrit les objectifs à atteindre et les grandes étapes prévues. U
 - [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. Le gate `pre.001` retient `cfg.std.wallet` + composite Wallet Desk, inventory `.kspwallet` root-scoped/symlink-safe, handles VIEW/OWNER côté Rust, identité autorisée + `getBalance`, administration OWNER/import/export déjà possédés par Wallet, CSP/capabilities Tauri minimales et un forecast regranularisé jusqu’à `pre.013`.
+- [ ] `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.002` — crate Tauri et shell Wallet Desk
+
+## Base requise
+
+```text
+0.2.6-pre.001-fix.002 appliquée
+workspace.package.version = 0.2.6-pre.1
+```
+
+Les validations opérateur de `pre.001` sont vertes : `cargo fmt --all`, audit structurel Python, `cargo check --workspace` et `cargo clippy --workspace --all-targets`.
+
+## Type de livraison
+
+```text
+ksp-general-0.2.6-pre.002.zip
+```
+
+Cette tranche est technique : création de crate, Rust/Tauri, frontend et configuration de build. Elle incrémente donc `workspace.package.version` vers `0.2.6-pre.2`.
+
+## Objet
+
+Matérialiser la première application `ksp-app-wallet-desk` sans commencer les fonctionnalités Wallet métier prévues à partir de `pre.003`/`pre.004`.
+
+Le delta fournit :
+
+```text
+crate Rust mixte lib + bin
+single-instance launcher
+normalisation CWD debug workspace
+bootstrap Config + Logging commun
+fallback Logging borné
+splash + main window
+bridge frontend -> Rust -> ksp-logging-lib
+DTO TS-RS foundation
+ports Vite/HMR 1432/1433
+Bootstrap
+Font Awesome
+DataTables Bootstrap 5 + Select
+SimpleBar
+resize-observer-polyfill
+shell Dashboard/Wallets/Create-Import/Details/Security/Diagnostics
+DataTable Wallet réelle mais volontairement vide en pre.002
+capabilities core:default + tracing:default
+CSP null comme Config Desk
+```
+
+## Frontières conservées
+
+`pre.002` ne dépend pas encore de `ksp-wallet-lib` ni de `ksp-onchain-transport-lib`. La seule composition KSP active dans la nouvelle app est celle nécessaire au gabarit desktop :
+
+```text
+ksp-app-wallet-desk
+    -> ksp-config-lib
+    -> ksp-core-lib
+    -> ksp-logging-lib
+    -> Tauri
+```
+
+Aucune logique `.kspwallet`, aucun inventory filesystem, aucun secret Wallet et aucun RPC ne sont simulés dans le frontend.
+
+## Frontend et npm
+
+Le `package.json` reprend la baseline Config Desk :
+
+```text
+@fltsci/tauri-plugin-tracing ^0.3
+@fortawesome/fontawesome-free ^7.3
+@tauri-apps/api ^2.11
+bootstrap ^5.3
+datatables.net-bs5 ^3.0
+datatables.net-select-bs5 ^4.0
+resize-observer-polyfill ^1.5
+simplebar ^6.3
+```
+
+Les outils restent dans `devDependencies`. Aucun script `check` standalone n'est créé. Les scripts `dev` et `build` existent uniquement parce que Tauri les appelle via `beforeDevCommand` et `beforeBuildCommand`.
+
+Lors de l'application de ce delta, l'installation initiale des packages se fait depuis la crate avec :
+
+```bash
+cd crates/ksp-app-wallet-desk
+npm i -D
+cd ../..
+```
+
+Le lockfile npm et `node_modules` restent non versionnés.
+
+## Dépendances auditées
+
+Au `2026-08-20`, les versions actuelles vérifiées incluent :
+
+```text
+@tauri-apps/api 2.11.1
+@tauri-apps/cli 2.11.4
+@fortawesome/fontawesome-free 7.3.1
+datatables.net-bs5 3.0.1
+datatables.net-select-bs5 4.0.0
+resize-observer-polyfill 1.5.1
+simplebar 6.3.3
+```
+
+Les ranges du gabarit couvrent ces versions sans changement de génération.
+
+## Shell et logging
+
+Le splash reprend les paramètres Config-owned existants :
+
+```text
+KSP_DESK_SPLASH_MINIMUM_MS
+KSP_DESK_SPLASH_FADE_MS
+```
+
+Le frontend instrumente :
+
+```text
+chargement main/splash
+navigation
+mise à jour DOM des vues
+initialisation DataTables
+clics d'actions shell
+IPC runtime status
+ordres/animations splash
+```
+
+Les targets frontend sont whitelisted (`frontend`, `main`, `splash`) avant réémission via `ksp-logging-lib`.
+
+## Tests ajoutés
+
+```text
+public API run()
+contrat Tauri ports/windows/beforeDev/beforeBuild/CSP
+baseline dependencies et absence de script npm check
+présence DataTables/Select/SimpleBar/ResizeObserver/Font Awesome
+capabilities initiales core + tracing seulement
+absence window.alert/confirm/prompt/localStorage/sessionStorage
+DTO CommandError sans context arbitraire
+whitelist frontend logging
+contrats splash
+```
+
+## Fichiers principaux ajoutés
+
+```text
+crates/ksp-app-wallet-desk/Cargo.toml
+crates/ksp-app-wallet-desk/build.rs
+crates/ksp-app-wallet-desk/capabilities/default.json
+crates/ksp-app-wallet-desk/package.json

+crates/ksp-app-wallet-desk/src/**
+crates/ksp-app-wallet-desk/frontend/**
+crates/ksp-app-wallet-desk/tests/**
+crates/ksp-app-wallet-desk/unit_tests/**
+```
+
+Les assets fonts/logo/splash/favicon sont repris du gabarit Config Desk.
+
+## Fichiers modifiés hors crate
+
+```text
+Cargo.toml
+ROADMAP.md
+docs/000-README.md
+docs/plans/013-V0_2_6_WALLET_DESK_PLAN.md
+```
+
+## Version technique
+
+```text
+workspace.package.version = 0.2.6-pre.2
+commit = v0.2.6-pre.002
+```
+
+Aucun tag stable.
+
+## Validation opérateur requise
+
+Après application :
+
+```bash
+cd crates/ksp-app-wallet-desk
+npm i -D
+cd ../..
+cargo fmt --all
+python3 scripts/audit_rust_workspace_rules.py
+cargo check --workspace
+cargo clippy --workspace --all-targets
+cargo test -p ksp-app-wallet-desk
+cargo tauri dev -c crates/ksp-app-wallet-desk/tauri.conf.json
+```
+
+Le parcours `cargo tauri dev` doit vérifier visuellement et dans les logs : splash, ouverture de la fenêtre principale, navigation des six vues, DataTable vide fonctionnelle, icônes Font Awesome, scrolling SimpleBar et bridge frontend Logging.
+
+`cargo tauri build -c crates/ksp-app-wallet-desk/tauri.conf.json` **n'est pas exécuté en `pre.002`** : il reste réservé à la toute dernière validation de la release conformément à `KSP-APP-034`.
+
+## Suite
+
+`pre.003` ajoute `cfg.std.wallet`, le composite Wallet Desk, `wallets_directory` global, `wallets_subdirectory` par profil et la préparation/création du répertoire effectif.

 Les validations opérateur du `2026-08-20` ont ensuite confirmé la base `pre.001` : `cargo fmt --all`, `python3 scripts/audit_rust_workspace_rules.py`, `cargo check --workspace` et `cargo clippy --workspace --all-targets` sont verts, sans warning signalé. Le présent plan intègre les corrections documentaires de `pre.001-fix.001` puis `pre.001-fix.002` sans modifier la version Cargo, car aucun fichier code/build/runtime/configuration exécutable n'est touché. `pre.001-fix.002` aligne en particulier le workflow frontend sur la règle KSP : npm direct sert uniquement à installer ou mettre à jour les dépendances ; les cycles dev/build passent exclusivement par Cargo/Tauri.
