+# 公交窄体双字号优化验收
+
+两款独立字格：类似公交窄体（推荐16px）8×16，类似公交窄体（推荐32px）16×32。每款6884码位，含6763个GB2312汉字。32px中文骨架来源GNU Unifont18.0.01，16px来源Fusion Pixel Font；官方材料、许可、锁定wheel、字模与修订理由随源码保存。正常构建离线完成，不读取Downloads附件。
+
+## 证据
+
+- glyphs-16、glyphs-32：全码位像素图册、audit.json和公交文字样张。全库无空字（空格除外）、灰阶和越格；重复仅ASCII空格/全角空格。
+- comparison：旧16、优化16、旧16直接放大、新32的四路比较，以及六类代表字。旧款仅作历史对照，没有登记为第三款可选字体。
+- 网页站名对比、网页包围字对比、网页密集字对比、字体选择器截图：实际后端文字层预览及选择器，不以浏览器原生字体代替帧。
+- visual-review.json：14页小字、27页大字及分类图的视觉复核记录和局限。
+
+## 本机验证
+
+字体/目录/模板/动图/图层/API定向回归89项通过；新增32→64px整数放大后，放大专项4项通过。Node字体选择器和场景模型24项通过。在含中文及空格的隔离目录新建venv，使用随交付wheel离线安装并重建，两款TTF及manifest字节一致，全字库像素校验通过。
+
+## 已验证经验
+
+Unifont BDF 的BITMAP行尾空格须先去除；单纯cmap覆盖检查不能发现空字。共享像素轮廓边需要抵消，避免FreeType灰阶接缝。字体版本使用缩略图辅助stamp及URL参数，不能修改作品修订号。板端完整测试多份字体占用使/run tmpfs不足，生产未切换；改用任务专属/var/tmp保存测试产物后重测。稳定要求与经验已补入测试相关资料/如何测试/核桃派点阵屏控制服务测试流程.md。
+
+## 边界
+
+分类规则生成与独立网格改绘分别记录，不把全部字形声称为逐字手工设计。16px复杂汉字仍需要简化；32px的硼、牖、鼬等少见密集字仍较拥挤，需要结合词语辨识。没有真实用户辨识率实验。主要站名和分类字的结构细节优于旧款直接放大；不能据此推断所有字同等易读。
+
+本轮不修改Android、不导出OTA/IMG、不推进VERSION，不启动摄像头或实屏测试图案。
+
+## 部署
+
+板端候选90项中89项通过，1项Node跨语言测试在板端跳过（本机已通过）。候选通过后保护运行目录，备份替换文件与登记字体，切换真实systemd服务。部署记录见deployment-result.json：446个其他持久文件摘要不变，变化仅为两款新增字体和摘要一致的旧字体删除。现有设备作品没有引用被更新字体，受影响缩略图数量为0；缩略图重建和不改修订的路径由候选测试验证。
+
+设备验证见device-verification.json与device-frames：15组最终帧与本机逐像素一致；旧摘要别名与优化16px相同。真实systemd服务重启后两款仍可选，持久数据摘要不变。22个部署代码/字体/登记/来源校验文件与本机摘要一致，旧程序资源不再存在。rollback.tar.gz为历史回滚备份，未登记为可选字体。更新前完整持久文件摘要保存在本项目被忽略的受保护本机材料中，不进入公开日志。
+
+cleanup-and-hashes.json登记已清理的板端目录：/run/matrix-screen-controller/bus-fonts-v2-20261012、/var/tmp/qms-bus-fonts-v2-tests-20261012，以及/var/tmp/qms-bus-fonts-v2-rollback.tar.gz。未清理其他设备材料。此前被策略拒绝的本机临时清理未重试或换方法绕过；本轮受保护基线和调试材料继续留在项目本机测试环境.local中。
