-- 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光标改为独立1像素细线，紧贴前后文字，保留真实空格、emoji与私密遮蔽；长文本仍保持光标可见。Android预览及示例编辑框去掉额外字间距。
+- 扩大26键，标准10/9/7三排；圆屏逐排按安全宽度收放，方屏充分利用宽度。
+- 点“abc”进入英文，再点“大写”切到大写，点“小写”恢复小写；按钮显示下一步动作，键面与实际输入同步。
+- 保留1.2.3未完成拼音补全、上下文续词及稳定刷新：全拼/九宫/14键同步支持；完全离线，密码不参与上下文。
 
-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。

 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)。

+# RTOS 1.2.4 光标、26键及大小写验收
+
+2026-11-14，版本1.2.4/10204。光标改为独立1像素细线，前后文字使用连续布局，保留真实空格、Unicode码点及私密遮蔽；长文本按预览宽度预算截取，使光标留在预览内。26键使用明确的10/9/7三排，扩大英文按键并按圆屏高度收放各排宽度。英文切换按钮显示下一步“大写／小写”，按当前状态规范提交字符，避免旧回调大小写错配。
+
+59项引擎和49项UX脚本断言通过。厂商gx v0.10.1/3ed38835、8192KiB内存，普通/QuickApp圆方四配置生产构建通过。104,837组索引、163,238候选完整保留，沿用1.2.3离线补全、上下文续词、候选稳定刷新及密码隔离。
+
+新增tests/console-native.py，使用自行启动、不启用Inspector的独立原生模拟器。将生产components/CrabInput/index.ux逐字节复制到自动运行的测试工程，仅增加测试入口并改变测试工程路由；报告记录生产源码SHA-256及各配置测试包摘要。没有连接或接管其他任务的Inspector14201。
+
+圆屏466×466、方屏390×450的普通/QuickApp四配置各24个状态，共96个原生状态通过。覆盖白蓝/黑绿两套主题，中文、词组、英文、混合emoji、开头/中间/结尾、长文及私密遮蔽光标；实测前文字—光标—后文字额外布局间距均为0px，光标宽1px。每配置检查拼音/英文与大小写的26个按键边界，圆屏逐个检查按键四角不超出半径231px安全区。四配置均通过@system.test真实点击切换并输入qQq，不以直接调用press替代点击。
+
+96张截图为上述原生测试工程的真实画面，未绘制替代UI；它们证明生产键盘组件在测试入口中的布局，不代表完整发布包的全套端到端验收。结果、原始日志、截图与源码摘要随验收ZIP提供。本版没有重跑原84项前后台交互；RTOS真机、固件接入、长期性能/功耗和商店审核未验收。

+# 1.2.4 RTOS原生组件截图
+
+以下画面来自独立原生模拟器测试工程，生产keyboard/index.ux逐字节相同，仅增加自动测试入口。四配置96个状态与96张截图通过，未使用替代绘图。这不是最终发布包的全套端到端验收；完整96张图、原始日志和源码摘要见1.2.4验收ZIP。
+
+UI_PREVIEW.png为本版圆屏英文小写画面。白蓝和黑绿主题、圆方屏26键及光标样例：
+
+![圆屏小写](1.2.4/round-bluewhite-en-lower.png)
+![圆屏大写](1.2.4/round-bluewhite-en-upper.png)
+![方屏全拼](1.2.4/rect-bluewhite-py-lower.png)
+![黑绿英文](1.2.4/round-blackgreen-en-lower.png)
+![圆屏文字中间光标](1.2.4/round-bluewhite-middle.png)
+![方屏文字中间光标](1.2.4/rect-bluewhite-middle.png)
+
+Android本版只有后台原生组件回归，没有前台截图。以下旧图片及旧说明均保留为明确的历史资料。
+
+## 历史截图记录
+
 # 截图版本说明
 
 当前1.2.3在OWW261上运行后台离屏原生组件测试，没有采集本版前台截图。UI_PREVIEW.png及下列图片分别来自历史1.2.2和1.2.0，不作为1.2.3前台视觉验收。
