-## 1.2.4 光标贴合、26键扩大与大小写切换
+## 1.2.5 减少内存、加速查词与等大26键
- 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。
+- 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。
- 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。
+- 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。
- 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。
+- 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。
 - 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 **59项引擎、49项UX及四配置生产构建通过**。独立原生测试工程中，生产键盘组件源码逐字节相同，圆/方普通及QuickApp四配置共96个状态全部通过，光标额外布局间距0px、26个按键边界合格；各配置均实际点击输入`qQq`。96张原生截图随验收ZIP提供。
+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。
-Android **7项Java测试及OWW261后台原生组件4项通过**，包含24帧非空绘制/控件复用、补全/续词、密码隔离、实际大小写切换和圆屏边界。Release APK/AAR、生产签名及API27元数据通过。上述是组件回归，未代替最终发布APK的前台端到端验收；本版未重跑原前台交互。RTOS截图来自明确标记的原生测试工程，Android截图为历史资料。
+这是Windows Node/V8的对比，数值随主机负载变化；不是Glyphix MCU/真实手表的内存、帧率或触控延迟。原始报告及执行脚本随源码/验收ZIP提供。

 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。
 1.2.5 取消过期SQLite查询，后台只创建整数分页计划，当前页才生成候选单元；文字更新复用键盘布局。26字母等宽等高并扩大触控区，圆方屏安全边界通过，保留大小写切换。8项Java和7项后台原生组件测试通过；验证范围见[本版验收](./VALIDATION_1.2.5.md)。

 # Android 1.2.5 内存、刷新及等大26键验收
 2026-11-14，版本1.2.5/10205，最低Android8.1/API27。
 候选分页只保留整数页起点，后台线程计算页计划，当前页才生成单元对象；不再每次查词创建所有候选页。取消旧Future同时通过CancellationSignal取消SQLite读取。预编译中文上下文正则。键盘结构未变时只更新文字及候选事件，不重建Placements或逐键重设样式；仍按帧合并刷新并复用控件，避免输入闪动。
 26字母维持标准10/9/7三排，以三排安全弦宽计算统一单元宽度，方屏充分使用宽度，缩小间距并增加高度。所有字母等宽等高（像素取整最多1px），保留明确的大写/小写按钮和qQq实际输入。圆屏同步保留底部操作区。
 8项Java测试通过，包含12,000候选的按需分页、全量顺序及完整性。Release APK/AAR、宿主、后台组件测试APK构建通过，SQLite无损回读104,837组索引/163,238候选。lint 0错误：演示1项备份声明警告，组件2项测试依赖提示。最终APK为1.2.5/10205，API27、zipalign、原生产证书1名签名者和v2签名通过。APK SHA-256：b61729cb9698be794c2eb406d3eb3c9c770ad727e67d6f2fdf722aa9f220eea2。
 OWW261 Android11/API30上7项后台离屏原生组件测试通过：24帧实际measure/layout/draw文字非空、控件不重建；相同尺寸连续24次文字/候选更新只创建一次布局；补全/续词只提交一次；密码上下文隔离；实际点击大小写切换输入qQq；模拟圆形466/192与方形466、390×450、192尺寸的26键等大、全部控件矩形及圆屏按钮四角边界；取消词库查询及后续恢复。
 测试未打开Activity、切换前台或修改系统默认输入法，使用debug组件，16个运行时class与发布AAR逐字节相同。最终APK没有安装到共享手表，原9项前台交互未重跑；这些组件测试不代替发布APK前台端到端视觉验收。没有新的Android前台截图。没有Android进程内存、真实打字延迟、长期功耗测量；另一款实体方表和商店审核未验收。

 初期两位编码分片曾触发原生模拟器内存回收，已改为四位编码分片。验收保持既有 `--memory-profile 8192`，没有通过增大模拟器内存规避问题。模拟器耗时不能替代真机帧率、延迟或功耗结论。

 # RTOS 1.2.5 内存、查词及等大26键验收
 2026-11-14，版本1.2.5/10205，8192 KiB原生模拟器配置。
 运行索引从91,357 B审计meta.json改为2,158 B的存在位图runtime.json；完整meta、原始词库和第三方声明保留。缓存限制3个分片及48,000个JSON字符，真正LRU，大分片不缓存，页面隐藏释放；清理期间的旧异步读取不能重新填满缓存。宿主同步工具同时复制运行索引。
 移除全词库entries/frequencies复制，26键直接定位输入前缀，九宫/14键保留相关分片消歧。补全只保留12个最优且未被完整匹配覆盖的候选，保留零词频补全。过期查询在读文件后结束。全部匹配结果仍可分页浏览；只有当前最多3项首页候选进入响应式数据，展开时建立整数页起点，翻页只创建当前最多16个单元；反应式字段40降至29。
 26字母维持10/9/7三排，三排使用一致的宽高。方屏利用全宽；圆屏调整上下留白、候选栏与模式栏，扩大字母触控区且保留完整底部操作。独立1px光标和大写/小写行为保持。
 ## 算法与构建
 59项引擎、49项UX、组件同步测试及普通/QuickApp四配置生产构建通过。词库保留104,837组索引、163,238候选，两种索引完整回读一致。24种编码的完整匹配及补全与1.2.4逐项一致；12,000个混合候选恢复为原顺序，808页且当前页最多15项；7,291个运行索引存在位与审计清单完全一致。另验证完整匹配/补全去重、零词频补全、旧清单兼容与清理隔离。
 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。
 这是Windows Node/V8的对比，数值随主机负载变化；不是Glyphix MCU/真实手表的内存、帧率或触控延迟。原始报告及执行脚本随源码/验收ZIP提供。
 ## 原生组件与视觉
 生产CrabInput组件逐字节复制到独立自动测试入口工程，报告保留组件和路由摘要。圆/方普通和QuickApp四配置共96状态/96张原生截图通过。检查8种文本/光标/私密状态、两主题与全拼/英文26键；26键宽高取整误差最多1px。模式切换与空格/删除/完成按钮同时检查矩形及圆屏四角安全边界；人工核对圆屏底部控件没有被父容器裁切。每配置实际点击字母和大小写按钮提交qQq。未使用或接管Inspector。
 这些是原生测试工程的组件回归，不是RTOS真实手表或最终发布包全套端到端验收。原84项整包前后台交互未重跑；RTOS真机、长期性能/功耗和商店审核未验收。

 # 1.2.5 RTOS原生组件截图
 以下是独立原生模拟器测试工程的真实画面，生产CrabInput组件逐字节复制，仅增加自动验收入口。圆/方普通及QuickApp四配置96状态/截图通过，26个字母等宽等高（像素取整误差最多1px），模式及底部按钮均检查边界；每配置实际点击大小写按钮输入qQq。完整日志、几何、96张图及源码摘要见本版验收ZIP。
 UI_PREVIEW.png为本版圆屏英文画面。不是RTOS真机或最终发布包的全套前台端到端验收。

 性能对比见[PERFORMANCE.json](1.2.5/PERFORMANCE.json)，是Windows Node/V8结果，不能当作MCU/手表内存或帧率。
 Android本版只有后台离屏原生组件回归，未提供新的前台截图。
