Purpose of the PR

No issue; the Chinese site is missing a page the English site has.

What changed

• Add content/cn/community/maturity.md, a Chinese translation of the Apache maturity assessment that already lives at content/en/community/maturity.md (moved there in feat: generate maturity to frontend #440). Same structure, same table IDs, same links, with internal links pointing to /cn/docs/... and /cn/community/....
• Clean up the English page: every table row was padded with non-breaking spaces (966 characters across 18 lines), which inflated the source and made the tables awkward to diff or edit. They are now plain spaces.
• Add the maturity page to HREFLANG_FALLBACKS in scripts/versioning.py and dist/validate-site-output.py so multi-version builds where older branches only carry the English maturity assessment resolve the fallback cleanly.

How verified

• hugo 0.168.0 extended (pinned in hugo.yaml) with go 1.27.3 passes strict build (--panicOnWarning --printPathWarnings --gc --minify); both /community/maturity/ and /cn/community/maturity/ render.
• scripts/validate-links.sh and pytest (290 passed, 1 skipped) pass.
• grep confirms no U+00A0 remains in either page.

Blocking: no. Summary: The Chinese page matches the English source row for row, and the English edit is whitespace-only. Three leftovers still send readers to English docs or mark the page as untranslated.

[bitflicker64]

Minor: This page links to the English docs on lines 27, 29, 45, 57, 66 and 69, though each target has a Chinese page under /cn/docs/. Point these links at the /cn/docs/... paths, as other content/cn pages do.

[bitflicker64]

Minor: data/landing/community/cn.yaml still calls this assessment 英文版, while its /community/maturity/ link renders as /cn/community/maturity/ once this page exists. Drop 英文版 from that sentence.

[bitflicker64]

Minor: HREFLANG_FALLBACKS in dist/validate-site-output.py and scripts/versioning.py still maps community/maturity/index.html to /cn/, so a full dist/validate-site-output.py run reports an hreflang mismatch for this page. Remove both entries.

[bitflicker64]

Blocking: no. Score: 9/10. Summary: content/cn/community/maturity.md matches the English page row for row, and the English edit only replaces padding with plain spaces. The Chinese doc links, the 英文版 label and the HREFLANG_FALLBACKS entries from the earlier review are fixed at this head.

Summary

The Chinese community entry still opens the English assessment.

Evidence

The unchanged absolute link renders to the English URL on the live site; the PR changes the label but retains that link. The landing Markdown rendering path does not localize the URL.

Validation notes

The PR-head local build could not run with the installed older Hugo; historical multi-version assembly was inspected statically.

⚠️ Link the Chinese assessment from the Chinese landing page

This Markdown link still points to /community/maturity/. The landing Markdown renderer preserves that URL, so visitors following it from the Chinese community page reach the English assessment even though the new Chinese page is available. Please change the target to /cn/community/maturity/.
