+## 1.2.5 减少内存、加速查词与等大26键

- 全拼、九宫、14键支持未完成拼音补全，按完整匹配、补全、较短前缀分层，结合词频及当前上下文排序；原始候选完整保留。
- 输入词语后提供离线续写，例如“你好→世界”；使用光标前最多4个连续汉字，最多8个联想，不保存上下文，密码不参与。
- Android复用文字与按键控件并合并同帧刷新；RTOS查询期间保留候选，旧候选在新结果到达前不能提交。
+- RTOS运行索引91,357→2,158 B，缓存3分片/48,000字符；去掉整份词库复制，隐藏释放缓存，过期查询停止后续工作。
+- 候选按需分页，首页只更新3项，展开才创建整数页计划，只生成当前页；RTOS反应式字段40→29。Android取消过期SQLite、后台规划候选页，文字变化复用键盘布局。
+- 26字母统一宽高并放大，标准10/9/7三排，方屏利用全宽，圆屏同步调整留白、候选与底栏。保留光标贴合和大写/小写切换。

-RTOS 53项引擎、42项UX及四配置构建通过。Android 7项Java测试及OWW261后台原生组件3项通过，包括24帧非空绘制、控件复用、补全/续写和密码隔离。本版未重跑前台交互；RTOS原生Inspector被其他任务占用，未接管。截图为明确标记的历史1.2.2界面，不冒充本版视觉验收。
+同一词库、24种全拼/九宫/14键编码，5轮共120次查询：总耗时 227.12 → 194.87 ms，P95 6.70 → 5.01 ms，中位数 1.01 → 1.07 ms；GC后保留堆 1,149,800 → 805,848 B。总耗时减少14.2%，P95减少25.2%，保留堆减少29.9%。中位数略增，不能称所有输入都提速。

+基于CrabKeyboard MIT词库，由herry重写的Android手表原生键盘组件，1.2.5 / 10205。提供可集成的 **AAR**、演示APK和独立接入示例；适用Android 8.1 / API 27及以上。

 应用接入后，点击自己的输入框自动展开内置键盘。**不注册系统输入法、不要求用户切换输入法、不改变系统默认输入法。** 圆屏按每行所在高度计算安全弦宽；4×4完整候选，单字16个一页，词组扩宽或增加行高，候选不显示拼音。九宫、标准QWERTY全拼/英文、14键、数字、三页符号、Unicode删除、按住连删及光标编辑。

 完全离线，无网络或外部存储权限；组件不持久化输入内容，不启用学习。密码输入默认英文并遮蔽预览。页面隐藏/销毁时清除组件会话与候选，宿主输入框中的内容仍由宿主决定如何处理。异步查询按会话序号隔离，旧结果不能回填新的输入框。

+
+1.2.4 去掉预览与示例编辑框的额外字间距，扩大26键；每排继续按实际屏幕弦宽计算安全边界。点“abc”进入英文，随后“大写／小写”按钮显示下一步动作，字母标签与实际输入保持一致。见[本版验收](./VALIDATION_1.2.4.md)。

 1.2.3 增加未完成拼音补全、上下文续写及词频排序；复用预览、按键及候选控件，按帧合并刷新。联想仅在内存中使用当前输入框光标前的中文，不持久化全文，密码内容不参与。见[本版验收](./VALIDATION_1.2.3.md)。

 1.2.2 去掉英文、数字、符号模式未使用的候选栏空位，文字与键盘紧密相接。本版真机间距检查通过；完整测试的限制见[验收记录](./VALIDATION_1.2.2.md)。
