Paper-note translation brief

Task

Translate one Chinese paper note into academic English.

Paths

• Read ONLY: _posts/zh/{CAT}/{YYYY-MM-DD-title}.md
• Write ONLY: _posts/{CAT}/{same-filename}.md (create {CAT} dir if needed)

Frontmatter rules

Keep layout, title, categories, tags, proceedings, date (and any other non-lang fields). Set:

• lang: en
• alt_url: /zh/{cat-lowercase}/{slug}/ where slug is the filename stem after the date with spaces → hyphens (same as Chinese permalink but without /zh prefix swapped: use Chinese file’s alt_url path under /zh/... — i.e. English alt_url = Chinese permalink)
• Do NOT include permalink on the English file (default / {cat} / {slug} / is correct)
• Remove Chinese-only fields if any

Body rules

• Academic English suitable for a research reading note
• Preserve all Markdown structure, headings, lists, tables, HTML <div> image blocks, links, URLs, and math ($...$ / $$...$$)
• Keep figure/table captions meaningful in English
• Do not invent facts, numbers, or citations; do not drop sections
• Keep paper/model names, acronyms, and code identifiers unchanged
• Blockquote paper links at top: translate labels like 论文地址 → Paper, 论文实现 → Code / Implementation

Done criteria

• English file exists at the target path
• No remaining Chinese prose (except unavoidable proper nouns)
• Frontmatter alt_url points to the Chinese permalink
