majiayu000 Scaffold the rule using the built-in script:
pnpm create-rule <name> <scope> <description><name>: kebab-case rule name (e.g.,vehicle-validation)<scope>: processor group (mass-id,credit-order, ormass-id-certificate)<description>: short description of what the rule validates

---name: create-rule-processordescription: Scaffold a new rule processor, implement the evaluation logic, and write tests.---
1. **Scaffold the rule** using the built-in script:
```bash
pnpm create-rule <name> <scope> <description>
```
- `<name>`: kebab-case rule name (e.g., `vehicle-validation`)
- `<scope>`: processor group (`mass-id`, `credit-order`, or `mass-id-certificate`)
- `<description>`: short description of what the rule validates
This creates the standard file structure:
```
{rule-name}/
├── {rule-name}.processor.ts
├── {rule-name}.lambda.ts
├── {rule-name}.processor.spec.ts
├── {rule-name}.lambda.e2e.spec.ts
├── {rule-name}.test-cases.ts
├── index.ts
├── project.json
└── jest.config.ts
```
2. **Implement the processor**: In `{rule-name}.processor.ts`, implement the `evaluateResult()` method. The processor extends `ParentDocumentRuleProcessor<RuleSubject>`.
3. **Write test cases**: In `{rule-name}.test-cases.ts`, define shared test data using `@faker-js/faker` and `zocker`. Never use real data (no real company names, tax IDs, addresses, etc.).
4. **Write unit tests**: In `{rule-name}.processor.spec.ts`, test the core evaluation logic using the shared test cases.
5. **Write e2e tests**: In `{rule-name}.lambda.e2e.spec.ts`, test the Lambda handler end-to-end.
6. **Apply to a methodology** (if needed):
```bash
pnpm apply-methodology-rule <methodology> <rule> <scope>
```
Example: `pnpm apply-methodology-rule carbon-organic vehicle-validation mass-id`
7. **Verify**: Run `pnpm lint:affected && pnpm ts:affected && pnpm test:affected` to confirm everything passes.
