FOSMVVM ViewModel Generator

Generate ViewModels following FOSMVVM architecture patterns.

Conceptual Foundation

For full architecture context, see FOSMVVMArchitecture.md | OpenClaw reference

A ViewModel is the bridge in the Model-View-ViewModel architecture:

┌─────────────┐      ┌─────────────────┐      ┌─────────────┐
│    Model    │ ───► │    ViewModel    │ ───► │    View     │
│   (Data)    │      │  (The Bridge)   │      │  (SwiftUI)  │
└─────────────┘      └─────────────────┘      └─────────────┘

Key insight: In FOSMVVM, ViewModels are:

Created by a Factory (either server-side or client-side)
Localized during encoding (resolves all @LocalizedString references)
Consumed by Views which just render the localized data

First Decision: Hosting Mode

This is a per-ViewModel decision. An app can mix both modes - for example, a standalone iPhone app with server-based sign-in.

The key question: Where does THIS ViewModel's data come from?

Data Source	Hosting Mode	Factory
Server/Database	Server-Hosted	Hand-written
Local state/preferences	Client-Hosted	Macro-generated
ResponseError (caught error)	Client-Hosted	Macro-generated

Server-Hosted Mode

When data comes from a server:

Factory is hand-written on server (ViewModelFactory protocol)
Factory queries database, builds ViewModel
Server localizes during JSON encoding
Client receives fully localized ViewModel

Examples: Sign-in screen, user profile from API, dashboard with server data

Client-Hosted Mode

When data is local to the device:

Use @ViewModel(options: [.clientHostedFactory])
Macro auto-generates factory from init parameters
Client bundles YAML resources
Client localizes during encoding

Examples: Settings screen, onboarding, offline-first feat...

A **ViewModel** is the bridge in the Model-View-ViewModel architecture:

```
┌─────────────┐      ┌─────────────────┐      ┌─────────────┐
│    Model    │ ───► │    ViewModel    │ ───► │    View     │
│   (Data)    │      │  (The Bridge)   │      │  (SwiftUI)  │
└─────────────┘      └─────────────────┘      └─────────────┘
```

**Key insight:** In FOSMVVM, ViewModels are:
- **Created by a Factory** (either server-side or client-side)
- **Localized during encoding** (resolves all `@LocalizedString` references)
- **Consumed by Views** which just render the localized data

## First Decision: Hosting Mode

**This is a per-ViewModel decision.** An app can mix both modes - for example, a standalone iPhone app with server-based sign-in.

**The key question: Where does THIS ViewModel's data come from?**

| Data Source | Hosting Mode | Factory |
|-------------|--------------|---------|
| Server/Database | Server-Hosted | Hand-written |
| Local state/preferences | Client-Hosted | Macro-generated |
| **ResponseError (caught error)** | **Client-Hosted** | Macro-generated |

### Server-Hosted Mode

When data comes from a server:
- Factory is **hand-written** on server (`ViewModelFactory` protocol)
- Factory queries database, builds ViewModel
- Server localizes during JSON encoding
- Client receives fully localized ViewModel

**Examples:** Sign-in screen, user profile from API, dashboard with server data

### Client-Hosted Mode

When data is local to the device:
- Use `@ViewModel(options: [.clientHostedFactory])`
