 作品分析：左侧原“竞品分析”统一为“作品分析”，页面通过“竞品账号”“我的账号”两个 TAB 严格区分作品来源；各 TAB 独立保留筛选与分页。支持所属账号、发布时间和互动阈值筛选，以及发布时间、点赞、评论、分享、收藏、24h 点赞增量升降序；自有作品额外支持观看量，不展示“时间核验状态”筛选。默认最新发布在前，条件变化回到第一页，筛选与排序作用于全部已采集作品后再分页；缺失指标显示“—”，排序放末尾、阈值筛选不将其当作 0。未采集作品不参与分析。
 
-评论聚合：独立页面通过“我的作品评论”“竞品作品评论”两个 TAB 严格区分来源，各 TAB 保留筛选与页码。列表展示评论发布时间、评论者、内容、所属账号（昵称与 UID）及对应作品；支持所属账号筛选，以及最近 1/6/12 小时、1/3/5/7 天筛选，默认最近 1 天。按评论发布时间计算范围，最新评论在前，同时间按评论 ID 倒序；未记录发布时间、未来时间及未采集评论不参与。筛选先作用于全部已采集评论再分页，条件或每页数量变化回到第一页；只读展示，不新增采集机制。
