- Real-time GPU model, driver version
- Memory usage (total/used/free)
- Utilization percentage with visual progress bar
- Auto-refresh every 5 seconds
- "Desktop" badge indicator

This section details on the original issue you should resolve

<issue_title>Add Tauri Desktop App Layer - Non-Invasive Migration</issue_title>
<issue_description>## Objective

Add Tauri desktop application layer to Heimdall without modifying existing frontend, backend, or infrastructure code. The Tauri app should serve as a standalone wrapper that packages the existing React frontend and Python services for desktop distribution.

Scope & Constraints

MUST NOT MODIFY:

• ❌ frontend/ folder (React code stays as-is)
• ❌ services/backend/ (no changes to logic)
• ❌ services/training/ (no changes to logic)
• ❌ services/inference/ (no changes to logic)
• ❌ docker-compose.yml, docker-compose.prod.yml
• ❌ .env structure or existing env vars
• ❌ Database models, API endpoints, or business logic
• ❌ Keycloak configuration or authentication flow

CAN ADD/CREATE:

• ✅ tauri/ folder (new, isolated)
• ✅ frontend/src/lib/tauri-bridge.ts (new, non-invasive utility)
• ✅ Root-level package.json scripts for Tauri
• ✅ Build artifacts and configuration files
• ✅ Documentation (optional but appreciated)

Requirements

1. Tauri Project Structure

Create tauri/ directory with standard Tauri scaffold:

tauri/
├── src/
│   ├── main.rs                  # Minimal bootstrap (~50-100 lines)
│   ├── commands/
│   │   ├── mod.rs              # Command registry
│   │   ├── data_collection.rs   # IPC: start/stop collection
│   │   ├── training.rs          # IPC: start/stop training, get status
│   │   ├── gpu.rs               # IPC: check GPU, get usage
│   │   └── settings.rs          # IPC: save/load app settings
│   └── lib.rs
├── Cargo.toml                   # Rust dependencies
├── tauri.conf.json              # Tauri configuration
└── build.rs                     # Optional: build script

2. Configuration

tauri/tauri.conf.json must point to existing frontend:

{
  "build": {
    "frontendDist": "../frontend/dist",
    "devPath": "http://localhost:5173"
  }
}

3. Tauri-React Bridge

Create minimal utility file frontend/src/lib/tauri-bridge.ts (non-invasive):

• Detects if running in Tauri desktop or web mode
• Provides unified API surface for IPC commands
• Graceful fallback for web deployment
• Type-safe TypeScript interfaces

4. Root Package.json

Update root package.json with Tauri scripts

5. Development Workflow

The app must support:

• Dev mode: npm run tauri:dev opens native window pointing to localhost:5173
• Frontend hot-reload: React changes reflect without restarting Tauri
• Production build: npm run build:app creates self-contained executable

6. Process Management

Tauri should handle:

• Spawning Python backend service as subprocess (optional, configurable)
• Graceful shutdown of child processes
• Environment variables passed to backend: DEPLOYMENT_MODE=desktop
• IPC communication between frontend React and Tauri Rust

7. GPU Detection

Implement basic GPU detection command

Deliverables

1. Tauri project fully functional and buildable
2. tauri-bridge.ts utility for React-Tauri communication
3. Root package.json updated with build scripts
4. Working dev environment
5. Production build produces distributable executable
6. No regression in Docker deployments

Non-Goals

• ❌ Modify frontend build process (Vite config stays unchanged)
• ❌ Embed database logic (backend handles it)
• ❌ Training orchestration (backend service handles it)
• ❌ Keycloak integration changes (use existing auth)
• ❌ Auto-updater implementation (out of scope)

Success Criteria

• ✅ npm run tauri:dev successfully launches desktop app with React frontend
• ✅ React components can call tauriAPI.* functions
• ✅ No changes to frontend/src/ core code (only new utility file)
• ✅ No changes to any service code (services/*/ unchanged)
• ✅ npm run build:app produces working executable
• ✅ docker-compose.yml and docker-compose.prod.yml continue to work independently
• ✅ Existing Docker deployments unaffected by Tauri addition

Implementation Notes

• Use official Tauri scaffolding tool
• Keep Rust code minimal and well-documented
• Prefer simplicity over feature completeness
• Focus on core IPC bridges (data collection, training, GPU info)
• Assume backend services handle heavy lifting

Timeline

Estimate: 2-3 days for completion

Platform Support

Target:

• Windows 10/11 (primary)
• macOS 10.13+ (secondary, if resources allow)
• Linux (AppImage format, if resources allow)</issue_description>

@copilot Ho notato nella configurazione che l'ingresso della webapp sarebbe localhost:3001, ma io so che quando parte con pnpm dev, parte sulla porta 3000, prego verificare.
Inoltre la documentazione va collegata, non abbandonata nella cartella.

Corretto! Ho aggiornato la configurazione Tauri:

1. Porta corretta: devUrl ora punta a http://localhost:3000 (commit d4d56c4)
2. Documentazione collegata: Aggiunto link a TAURI_INTEGRATION.md nella sezione Reference del README

La documentazione è ora accessibile da README → Reference → Tauri Desktop Integration

@copilot No, mi sono sbagliato vite parte sulla porta 3001, avevi ragione prima, rimettilo a posto

@copilot No, mi sono sbagliato vite parte sulla porta 3001, avevi ragione prima, rimettilo a posto

Fatto! Ripristinata la porta 3001 nella configurazione Tauri (commit 72af8c7). La configurazione originale era corretta.

@copilot Bene, ora DELICATAMENTE inizia ad adattare il frontend in modo che lavori usando le chiamate alle feature di tauri invece che le chiamate al backend dockerizzato tramite apigateway, se è necessario al funzionamento, altrimenti non farlo, ma inizia a fare sì che la app funzioni davvero, ecco. Trovi i dettagli su come fare in docs/TAURI_INTEGRATION.md

Fatto! Ho integrato delicatamente le funzionalità Tauri in due pagine chiave (commit e61f1b7):

SystemStatus - Monitoraggio GPU (solo desktop):

• Informazioni GPU in tempo reale (modello, driver, memoria)
• Utilizzo GPU aggiornato ogni 5 secondi
• Indicatore visivo "Desktop" sul card
• Nascosto completamente in modalità web

Settings - Persistenza impostazioni (desktop):

• Caricamento automatico da storage locale
• Salvataggio su disco in modalità desktop
• Badge "Desktop Mode" nel titolo
• Fallback graceful per modalità web

Le modifiche sono non-invasive: solo 185 righe aggiunte in 2 file, zero impatto sul funzionamento web. L'app funziona identicamente in entrambe le modalità, con feature desktop che appaiono automaticamente quando disponibili.

@copilot Domanda: la app ha due diverse modalità di build? Dovrebbe Esistere una build per l'app dotata di capacità di training locale, e una per la modalità solo di inferenza. Entrambe le app, e il sito dockerizzato anche lui, devono essere in grado di consentire all'utente di salvarsi i progressi fatti in un formato facile da leggere/riparare. Nel file di salvataggio, che avrà estensione .heimdall e sarà essenzialmente un JSON molto grande, dovranno essere presenti varie sezioni opzionali per salvare le seguenti cose:

• I settings utente
• Le Sources
• Le WebSDR
• Le Sessioni (sia i metadati della sessione che la sessione stessa, cioè il registrato)
• Il modello addestrato fino a quel momento
• Il modello di inferenza finito e funzionante

I salvataggi devono poter essere scritti ma anche letti, e i dati devono venire ripristinati facilmente da un Heimdall all'altro

La sezione che consentirà di fare ciò si chiamerà Import/Export

Risposta alla domanda: Attualmente l'implementazione Tauri non ha modalità di build separate. La build unica include tutti i comandi IPC (training, inference, GPU, settings).

Riguardo Import/Export: Questa è una feature significativa che richiede:

1. Backend API - Implementazione in services/backend/ per export/import dei dati (sessions, models, websdrs, sources)
2. Frontend UI - Nuova pagina/sezione Import/Export
3. Formato .heimdall - Schema JSON con sezioni opzionali
4. Tauri commands - File system operations (save/load .heimdall files)

Questa funzionalità va oltre lo scope originale "non-invasive Tauri wrapper" e richiederebbe modifiche sostanziali al backend.

Posso procedere in due modi:

• A) Implementare solo la parte Tauri (save/load file locali) lasciando l'export/import dati al backend esistente
• B) Implementare l'intera feature (backend + frontend + Tauri)

Quale approccio preferisci? E questa feature è parte dell'issue #88 o dovrebbe essere una nuova issue separata?
