[PlevanTem]

Summary

• Add a validation-methods section to both English and Chinese architecture diagrams.
• Separate deterministic repair-grid checks, visual review of all primary assets, and manifest/export gates, with the scope and checks shown for each.
• Update README and architecture alt text to describe the validation dimensions.

Validation

• git diff --check
• Parsed both SVG files as XML and verified the method labels/content.

Risk

• Documentation and diagrams only; no runtime behavior changed.
