caoqianming e695e04de7 fix(resm): 识别 Elsevier 摘要预览 PDF, 避免误标全文 ... Elsevier Article API 对未授权/in-press 文章, application/pdf 端点会返回仅含 摘要的 1 页预览 PDF (魔数仍是 %PDF、体积也不小), 而全文 XML 可正常获取。旧逻辑 只校验魔数+体积, 误将预览页落库并置 has_fulltext_pdf=True。 - tasks.py: 新增 _pdf_page_count / _is_elsevier_preview_pdf (优先 pypdf, 退化 字节扫描), _elsevier_fetch_pdf 与 save_pdf_from_elsevier 落库前排除 1 页预览页, 打 fail_reason=elsevier_pdf_preview_only; 补抓队列 qs_pdf 排除该标记避免无限重试 - 新增管理命令 fix_preview_pdf: 扫描存量误标记录, 回退 has_fulltext_pdf; 无 XML 全文者一并回退 has_fulltext, 让其重进下载链 - requirements.txt: 增加 pypdf>=4.0.0 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>		2026-06-29 08:54:07 +08:00
