- alembic 0008:articles 加 is_short_news/external_id/source_ref/content_hash (UNIQUE);sources.kind 加 'api_push';api_tokens 加 purpose + source_id - SourceKind.API_PUSH enum;Article/ApiToken model 加新字段 - enrichment_article 短新闻跳过 format/image; enrichment_loop SQL 加 is_short_news 路径(并入'可 enrich' 条件) - 入库侧由 commit 2(ingest 接口)负责:写 body_zh_text=body_text, format/image/commentary_meituan_status='n/a', classify/commentary_status='pending'(带 tags 时 classify='ok') 无迁移爆炸半径:articles.url 保持 NOT NULL,短新闻合成 api-push:// 占位
