### Proposed Category
Compliance

### Additional Context
This extension is powered by a real API backend deployed on Tencent Cloud SCF. The same backend powers our ClawHub skills (cn-seo-optimizer, cn-geo-monitor, china-data-compliance) which have been battle-tested with real users. China compliance is a unique niche with no existing spec-kit extensions covering it.
