轮播 feed(marquee_seed,全新): - 新增 marquee_seed 表 + admin CRUD/批量生成/预览;真实比价记录(success 且 0<省额≤300元、按 user 去重)优先,种子兜底混播 - 种子为「生成规则」:用户名可空(空则按脱敏格式随机合成、避开同屏撞名),金额改 [min,max] 区间随机,feed 公平随机抽取(不看 sort_order) - 新增 GET /api/v1/platform/savings-feed(无鉴权);展示时间统一刷新为相对当前的最近时刻 三统计配置(platform_stat_display)增强: - 自增长新增「绝对增量」方式(random_kind=add,每周期 +[step_min,step_max]) - 真实值模式加基数偏移(real_offset,展示=真实+偏移) - 只增不减护栏(allow_decrease 默认关,real/manual 不回退防门面缩水) - 累计节省 real 口径只计 0<单条≤300元防虚高;倍率上限 5.0→1.5;PATCH 支持 apply_now 立即更新 迁移:marquee_seed_table / marquee_seed_range / platform_stat_growth_offset(均可逆,已验证) 文档:API/DB 对应文档同步更新 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
