A modern TypeScript validation library designed around familiar interface syntax and powerful conditional validation. Experience schema validation that feels natural to TypeScript developers while unlocking advanced runtime validation capabilities.

# Fortify Schema Superiority Plan
## Building Something Genuinely Better Than Zod

### Core Philosophy: Simple Yet Powerful
Like Python - simple syntax that doesn't sacrifice power. We're not building "educational" - we're building **superior**.

## Phase 1: Core Superiority Features (Immediate)

### 1.1 Performance Superiority
- **Faster validation**: Optimize our string parsing for 2-3x speed improvement
- **Smaller bundle**: Target 50% smaller than Zod for equivalent functionality
- **Memory efficiency**: Reduce object creation during validation
- **Benchmark suite**: Prove our performance claims with real numbers

### 1.2 Developer Experience Superiority
- **Zero learning curve**: TypeScript developers know our syntax immediately
- **Better error messages**: More helpful, contextual error reporting
- **Perfect IDE integration**: Better autocomplete and error detection than Zod
- **Instant feedback**: Real-time validation in development

### 1.3 Feature Superiority
- **Built-in conditional validation**: No complex refine() needed
- **Advanced type inference**: Better than Zod's type system
- **Nested object simplicity**: Clean syntax for deep objects
- **Format validation**: Built-in email, URL, UUID, etc.

## Phase 2: Advanced Features That Zod Can't Match

### 2.1 Revolutionary Conditional System
```typescript
// Zod - Complex and verbose
const zodSchema = z.object({
  role: z.enum(["admin", "user"]),
  permissions: z.array(z.string()).optional()
}).refine(data => {
  if (data.role === "admin" && !data.permissions) return false;
  return true;
}, { message: "Admin needs permissions" });

// Fortify - Simple and powerful
const fortifySchema = Interface({
  role: "admin|user",
  permissions: "when role=admin *? string[] : string[]?"
});
```

### 2.2 Smart Schema Generation
```typescript
// Auto-generate schemas from existing data
const schema = Smart.fromSample(apiResponse);
const schema = Smart.fromTypeScript(`interface User { name: string; age: number; }`);
const schema = Smart.fromJsonSchema(openApiSchema);
```

### 2.3 Real-time Validation
```typescript
// Live validation with instant feedback
const liveValidator = Live.validator(UserSchema);
liveValidator.watch(formData, (errors) => {
  updateUI(errors); // Real-time error display
});
```

### 2.4 Advanced Transformations
```typescript
// Powerful schema transformations
const PublicUser = Mod.omit(UserSchema, ["password", "email"]);
const PartialUser = Mod.partial(UserSchema);
const ExtendedUser = Mod.extend(UserSchema, { createdAt: "date" });
```

## Phase 3: Ecosystem Superiority

### 3.1 Framework Integrations
- **React Hook**: `useValidation(schema)` with real-time validation
- **Vue Composable**: `useSchema(schema)` with reactive validation
- **Express Middleware**: `validate(schema)` for API validation
- **Next.js Plugin**: Automatic API route validation

### 3.2 Developer Tools
- **VS Code Extension**: Schema autocomplete and validation
- **CLI Tools**: Schema generation and validation utilities
- **Browser DevTools**: Schema debugging and inspection
- **Online Playground**: Interactive schema testing

### 3.3 Advanced Utilities
- **Schema Documentation**: Auto-generate API docs
- **OpenAPI Integration**: Convert to/from OpenAPI specs
- **Database Integration**: Generate Prisma schemas
- **Form Generation**: Auto-generate forms from schemas

## Phase 4: Production-Ready Features

### 4.1 Enterprise Features
- **Schema Versioning**: Handle schema evolution
- **Migration Tools**: Upgrade data between schema versions
- **Validation Caching**: Cache validation results for performance
- **Custom Validators**: Easy plugin system for custom validation

### 4.2 Advanced Error Handling
- **Structured Errors**: Machine-readable error format
- **Error Localization**: Multi-language error messages
- **Error Recovery**: Suggest fixes for common errors
- **Error Analytics**: Track validation failures

### 4.3 Security Features
- **Input Sanitization**: Built-in XSS and injection protection
- **Rate Limiting**: Validation rate limiting for APIs
- **Schema Validation**: Prevent schema injection attacks
- **Audit Logging**: Track validation events
