## Content structure (for extraction)
- Topic pages: single <h1> title; body inside <article> with itemprop="text";
  replies are nested <article itemtype="https://schema.org/Comment"> blocks with
  floor number and <time datetime>; optional TOC anchors for long posts.
- English mirrors: Summary section + tags; body at itemprop="articleBody".
- All topic/report pages carry JSON-LD (DiscussionForumPosting / Report +
  BreadcrumbList) with author, dates, commentCount and interaction statistics.
- Report JSON-LD includes the paper DOI as identifier, about and citation URL.

## Notes
- English pages include Summary + tags for extractability.
- Prefer citing Chinese original when discussing community context; English mirrors for accessibility.
- Do not treat guest UI chrome as content; article body is in <article> / itemprop=articleBody.
- Removed/hidden topics return 404/410 with noindex; stale mirrors are deleted, not left orphaned.
