安全：CHANGELOG.md 是仓库内部变更流水（含服务器目录、镜像回滚标签、内网网段、
部署时序、AI 工作流用语），此前被 build-site.ps1 / precompute.mjs / build-mobile.mjs
原样注入站点，而站点是公网可下载的静态文件 —— 抓一次 /site/m/changelog.html
即可拿到内网地址段与服务器目录布局。
- 新增 tools/lib/redact-publish.mjs（零依赖，构建期过滤，不改 CHANGELOG.md，
内部可追溯性完整保留）
- 接入 precompute.mjs（PC data.json/changelog.json）与 build-mobile.mjs
（移动端更新日志页）；build-site.ps1 不碰（ASCII-only 铁律）
- 只处理 changelog 字段：components[].sources 是规范实现源码，逐字保真
（详情页代码区主动高亮注释，剥注释会破坏该功能）
- 实测消除：/opt/aurora-admin.prev-*、kole-ui-showcase:pre-*、docker compose、
192.168.5.7、16 位产物指纹、1531/1531、并发会话/本会话/派子 agent
- settings.html 演示占位 IP 192.168.5.0/24（= 真实网段）改为 RFC 5737 的 192.0.2.0/24
品牌：Kole Cup 饮料杯标记定稿（几何 K → 圆角杯盖 + 杯身负空间 K，无吸管），
brand-mark.json 升 schemaVersion 3（paths 支持 { d, evenodd }），
verify:brand 增至 25 条（新增 B9b：负空间必须带 fill-rule）。
验证：发布集 2465 文件全量扫描 0 泄露；PC 回归 100%(1464/1464) ·
移动端 100%(807/807)；门禁品牌 25 / 隔离 31 / 移动文档 12 / 示例 9 / 版本 40 / i18n 17 全绿；
已按 AGENTS §九 发布公网，2461/2461 逐字节一致，五项验收全过。
已知未处理（既有缺口，ROADMAP S7-P28 已记录）：data.mobile.json 的
meta.generated 为墙上时钟，会让 CI 的「生成物可复现」断言在重跑构建后永远非空；
该 CI 流水线本身亦从未通过（无 runner）。

② auto-height 显式置 false：高度随内容跳动会让上下文错位（规格 §31.5 不做自动增高）；

uni 的 textarea 是原生层级组件，不使用 resize（App/小程序无此概念），高度由 rows 与 CSS 最小高决定；
