The maintained Chinese foundation covers:

* What OpenSpec is and why it matters for AI coding.
* The mental model of `specs`, `changes`, artifacts, and archive.
* The basic workflow from proposal to archive.
* How to write artifacts and delta specs.
* Schema extension and applicability boundaries.
