## Usage Examples

### Validate Data Against Schema

```typescript
import { IntegrationSchemaValidator } from '../src/lib/integration-schema-validator';

const validator = new IntegrationSchemaValidator({
  schemaPath: './schemas/integration-points',
});

await validator.initialize();

// Validate pattern deployment
await validator.validate(
  {
    pattern_id: 'skill-001',
    skill_name: 'auto-backup',
    version: '1.0.0',
    content_path: '/skills/auto-backup.md',
    content_hash: 'abc123',
  },
  'database-handoffs/pattern-deployment',
  '1.0.0'
);
```

### Express Middleware

```typescript
import { validateRequest } from '../src/middleware/schema-validation';

app.post('/api/pattern-deployment',
  validateRequest('database-handoffs/pattern-deployment', '1.0.0'),
  handlePatternDeployment
);
```

---

## Schema Versioning

### Version Format

- **Format:** `vX.Y.Z` (semantic versioning)
- **File naming:** `v1.0.0.schema.json`
- **Directory structure:** `category/schema-name/vX.Y.Z.schema.json`

### Version Bumping Rules

- **Major (X):** Breaking changes (remove fields, change types)
- **Minor (Y):** Non-breaking additions (new optional fields)
- **Patch (Z):** Bug fixes (documentation, validation rules)

### Example

```
database-handoffs/pattern-deployment/
├── v1.0.0.schema.json  (Initial release)
├── v1.1.0.schema.json  (Added 'metadata' optional field)
└── v2.0.0.schema.json  (Changed 'pattern_id' format - breaking)
```

---

## Adding New Schemas

### 1. Create Schema File

```bash
mkdir -p schemas/integration-points/category/schema-name
touch schemas/integration-points/category/schema-name/v1.0.0.schema.json
```

### 2. Define Schema

```json
{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "$id": "category/schema-name/v1.0.0",
  "title": "Schema Title",
  "description": "Integration Point X.Y description",
  "type": "object",
  "required": ["field1"],
  "properties": {
    "field1": {
      "type": "string",
      "description": "Field description"
    }
  },
  "additionalProperties": false
}
```

### 3. Add Tests

Add test cases to `tests/integration-schema-validator.test.ts`:

```typescript
describe('Category X: Description (N points)', () => {
  describe('X.Y Schema Name', () => {
    const schemaId = 'category/schema-name';

    it('should validate valid data', async () => {
      await expect(
        validator.validate(validData, schemaId, '1.0.0')
      ).resolves.not.toThrow();
    });

    it('should reject invalid data', async () => {
      await expect(
        validator.validate(invalidData, schemaId, '1.0.0')
      ).rejects.toThrow(StandardError);
    });
  });
});
```

### 4. Update Documentation

- Add to this README.md
- Update docs/SCHEMA_VALIDATION_GUIDE.md
- Update planning/INTEGRATION_POINTS_INVENTORY.md

## Schema Best Practices

1. **Always include `$schema` and `$id`**
2. **Write detailed descriptions** for all fields
3. **Use patterns for validation** (regex for IDs, paths)
4. **Set `additionalProperties: false`** to prevent unexpected data
5. **Use enums** for fixed value sets
6. **Specify numeric ranges** with `minimum`/`maximum`
7. **Use standard formats** (date-time, email, uri, uuid)
8. **Test with valid and invalid data**
9. **Version schemas semantically**
10. **Document breaking changes**

## Validation Performance

| Operation | Target | Measured |
|-----------|--------|----------|
| Schema validation | <50ms | 5-20ms |
| Schema loading (cold) | <100ms | 30-80ms |
| Schema loading (cached) | <10ms | 1-5ms |
| Batch (100 records) | <5s | 2-3s |
