- number_rules 新增 mode(date_seq 日期+序号3位按周期重置 / seq 连续6位)与 seq_period 列 - 单号生成按 mode + date_format 拼接，跨日期周期自动重置；启动回填 product→seq - 商品建号接入 number_rules(seq 模式、前缀可配、从现有最大序列号播种，续发连续编号) - 设置屏：加「模式」列、当前序号按周期显示(未开单显0)；编辑弹窗前缀所有类型可改， 有日期的序号系统自动(只读置灰)、可改日期格式，商品编码序号可调大不可调小 - 桌面原型 settings 补「编号规则」面板+编辑弹窗、m-settings 改准；atoms 去数字框原生箭头 - 同步 CONTRACT / screens.mjs / db-schema.html 与 settings fidelity 基准 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Bupi8Kdqkfx2N5acFsHTx5
