R8.1: document content keeps the file's colours in a dark app

Pages, cells, slides and PDF pages paint as the file says in any appearance; only the chrome around them follows dark mode. The kernel keeps Ely's one light scheme, sent once a view, and MuPDF no longer inverts. Reviews now run gpt-6.1-sol at xhigh. Co-Authored-By: Claude <noreply@anthropic.com>

 - 2026-10-05（用户定）：ElyAgent 的后端与内置模型的登录配置以 Kigi CLI（https://git.zacharyzhang.com/ZacharyZhang-NY/Kigi-CLI，Rust）为基础，以 Rust 依赖直接嵌入，不用 ACP；沿用其提供商登录（订阅账号或 API 密钥）与模型配置。
 - 2026-10-05（用户定）：八个应用都不许卡顿：键入、选择、滚动、文档渲染都要即时（GPUI 的 120 FPS 手感），树莓派 3 上也要流畅。输入延迟与帧时间是验收项，要实测；界面线程不等内核、不持 worker 锁做同步请求，空闲不做事。
 - 2026-10-05：LOK 的输入与事件路径（实测后定）。原样：视图的事件监听长轮询 worker（持 worker 锁最多 50 毫秒，worker 读线程也随之阻塞最多 250 毫秒），按键排在锁后，键入锁等待中位 290 毫秒、最长 9 秒；输入队列在界面执行器上逐条跳回界面线程，每键约一帧，连续键入积压到 1 至 2 秒。现在：worker 有新事件即主动推送（`tag::EVENTS`，推送线程在输出锁下取批，批次即发送时状态），客户端读线程把回复与事件分开，事件存入 `client::Feed`，视图以异步方式等它（`Feed::next`，有新批次时唤醒，不占线程、不碰 worker 锁；原先每个打开的文档阻塞一个后台线程最多一秒，文档多于核数时会饿死输入与图块；监听任务归视图所有，视图释放即停）；每个视图一条后台通道（`view/lane.rs`），输入优先、图块其次，连续执行，界面线程只收落地结果；文档尺寸与页框只在内核报尺寸变化时在后台读；批次弄脏的已显示图块即刻重绘，不等下一帧；视图的 `Reported` 事件只在内核回报或输入落地时发出，滚动与图块到达不触发应用的观察钩子；编辑与光标移动后应用要读的内核列表（ElyDoc 导航、字数、审阅，ElyTable 工作表与几何、单元格规则、格式面板）经 `ely_lok::read_off` 在后台读，一次一个，结果按发起者核对。实测（macOS，`tests/scripts/lag.sh`）：按打字速度键入时输入落地 0 至 1 毫秒，图块 1 至 3 毫秒，按键到新图块 ElyDoc 中位 19 毫秒、ElyTable 3 毫秒；连续快速键入（脚本一次送出近百字）时，各次运行在 3 至 225 毫秒的中位之间摆动：新文档首次键入时内核有一次 150 至 230 毫秒的冷启动（首块图块与拼写等初始化），同一批字排在它之后；原为中位 1 秒、p95 1.9 秒。树莓派 3 未实测（本机无设备）。界面线程不碰 worker：应用对内核的读取、保存与另存为的导出、导出 PDF、比较、邮件合并都经 `Tabs::read_in`（或 `ely_lok::read_off`）在后台执行，回到窗口时按发起的标签与读取时的状态核对；保存导出期间标签状态为“正在保存”，同一标签的后续保存排队到它结束；另存为在写入前按文件身份再查一次目标是否已被别的标签持有；导出期间又有编辑时，“保存后关闭”不关闭，回到关闭询问；关闭标签时的撤销历史也在后台读；邮件合并预览与比较在发起时就保留自己的标签号与工作目录；读取失败不立即重试，等下一次状态变化；载入时一并在后台读版面与撤销历史（`ely_lok::layout`，`LokView::open` 接收版面）。窗口关闭回调先不放行，在后台逐个读标签的撤销历史并关闭（有改动的照常询问），最后一个标签关闭后移除窗口；内核文档的关闭也在后台（2026-10-06 起，原先同步读历史、在界面线程持 worker 锁关闭）。
- 2026-10-04（用户定）：八个应用的内容区一律随系统深浅色：Doc 页面、Table 网格、Show 幻灯片、PDF 页面、邮件正文、Mark 编辑区、Agent 输出。自动颜色随之翻转，文件里写明的颜色照原样；打印与导出 PDF 仍为浅色。各引擎（LOK、MuPDF）接入应用主题，不留引擎默认色。LOK：`ely.xcd` 定义 `COLOR_SCHEME_ELY_DARK` 与 `COLOR_SCHEME_ELY_LIGHT`（文档底色、自动文字色、网格、链接等取 Ely 默认色板；内核自带的深色方案颜色留空、按应用外观取默认值，传方案名不改外观，所以不用它），`LokView` 在主题深浅变化时经有序队列发 `.uno:ChangeTheme`（不算编辑），页面底色深色取 `surface`、浅色取 `paper`；Omarchy 色板与这两套固定色可能略有差别。导出 PDF 实测仍为白底。图块作废时旧图仍显示，新图到达后替换，编辑与主题切换都不闪。
+- 2026-10-04（用户定），2026-10-18 改（用户定）：Doc 页面、Table 单元格、Show 幻灯片、PDF 页面在任何外观下都照文件原色（白底即白底），只有页面四周的界面随深浅色；邮件正文、Mark 编辑区、Agent 输出随系统深浅色。LOK：`ely.xcd` 只有 `COLOR_SCHEME_ELY_LIGHT`（文档底色白、自动文字色黑、网格、链接等）；方案按视图记（LOK 下全局改动只作用于当前视图），每个 `LokView` 首帧经有序队列发一次 `.uno:ChangeTheme`（`ely_lok::SCHEME`，不算编辑），ElyShow 放映与输出的副本同样各发一次；旧版写进内核配置的 `COLOR_SCHEME_ELY_DARK` 已删，内核读不到即退回自动方案，首帧的那次改回 Ely 方案。页面底色 `ely_lok::paper()` 为白，同方案的 `DocColor`。MuPDF 照原样画，不反相。图块作废时旧图仍显示，新图到达后替换，编辑不闪。
 - 2026-10-01：主题。`Appearance` 为系统、浅色、深色。系统档在有 Omarchy 时跟随 Omarchy（`ThemeSettings::omarchy_sync`）。读 Omarchy 的 `$HOME/.local/state/omarchy/current/theme/colors.toml`（Omarchy 写死此路径，不随 `XDG_STATE_HOME`），目录由 `ELY_OMARCHY_DIR` 可改。读法与回退链照 `reference/omarchy/bin/omarchy-theme-color`：松散引号、`colorN`、`purple`、`selection_background`、`theme_type`、`light.mode`、亮度和 382 比。缺的色相用 Ely 自己的色并警告。色板照组件库 `A11yChecker` 的规则收口：正文、状态色、代码色在各自的表面上 4.5:1，焦点与图表色在页面上 3:1；先拉近前景再拉到纯黑白，最后逐项核对，核对不过的主题整套忽略。切换时 Omarchy 先暂存 `next-theme` 再整体替换 `theme`，用文件监视跟随，不用它的钩子。新主题无 `colors.toml` 时退回 Ely 色板。`ELY_APPEARANCE`、`ELY_OMARCHY_SYNC`、`ELY_REDUCE_MOTION` 是覆盖开关，设置页接入前先用环境变量。

 - 2026-10-10：Windows 与 Linux 的内核与 worker（W-01、K-01，用户定：0.1.3 先三端发布）。内核只认合并库（`ffi::KERNEL`：`libmergedlo.dylib`、`libmergedlo.so`、`mergedlo.dll`；`sofficeapp` 在合并构建里是文本占位）；Windows 载入时一并搜索该 DLL 所在的 `program/`。查找次序照旧，Windows 与 Linux 的包内位置是应用旁的 `libreoffice/program`，开发构建为 `engines/lo-src/instdir/program`。worker 的主循环：macOS 照旧以 GCD；Linux 以 unipoll，`runLoop` 的轮询回调里每次答一个请求，内核的唤醒回调往同一队列放信号（`worker/unipoll.rs`；回调的数据指针须非空，VCL 见空即不调用）；Windows 也以 unipoll：LOK 不另起主线程，worker 的主线程跑 `runLoop`（Windows 的消息循环），请求经只收消息的窗口投到这条线程上执行（`worker/messages.rs`），同 macOS 的 GCD；原先 LOK 自起主线程、worker 在另一线程作答，载入表格即死锁。Windows 的循环不调轮询回调，但须传非空的回调，`isUnipoll` 只看它。补丁 `0043-lok-callbacks-flush-inline-everywhere.patch`：回调队列在各平台都即时冲出（原只 macOS），否则请求里等的命令结果与状态要等下一轮主循环才到。`0042-svx-boost-json-needs-no-library.patch`：svxcore 与 sd 定义 `BOOST_ALL_NO_LIB`，MSVC 不再按 Boost 的自动链接索要 `libboost_json`、`libboost_container`。Linux 的内核以 cairo 画图块（worker 设 `SAL_DISABLESKIA`；构建去掉 `--enable-cairo-rgba`，自带的 cairo 要清掉重建），字节为 BGRA，同 macOS 与 Windows；`getTileMode` 只看 cairo 开关，不可信。worker 启动核对在三端都画一段红字，按 BGRA 找不到红色即拒绝。`scripts/apply-lo-patches.sh` 的临时库设 `core.autocrlf false`（Windows 默认转换使任何前缀都对不上）。Windows 的 LibreOffice 在 Cygwin 下构建（`build-libreoffice.sh` 的 CYGWIN 分支：去掉 Unix 专用开关，加 VS 2022，用 `/opt/lo/bin` 的 make，清掉 Git Bash 带进来的 `MSYSTEM`）；构建目录与 Cygwin 排除在 Defender 扫描之外（否则并行 configure 删不掉 `conftest.dir`）。英文词典扩展里的 Lightproof（Python 写的语法检查）在构建后删去：macOS 与 Linux 的内核不带 Python，它本不生效；Windows 必带内置 Python（Cygwin 下 configure 不许去掉），第二次用同一配置启动时初始化它，worker 挂起。worker 以 `SAL_NOLOCK_PROFILE` 运行，`ely.xcd` 关掉 LibreOffice 的文档锁（`Common/Misc/UseLocking`）：被强杀的 worker 留下的锁会让下次启动或载入弹出交互而挂起；每个应用只有一个 worker 用自己的配置，冲突由 Ely 自己核对。三端发布（CI-01）：`.gitea/workflows/release.yml` 在打标签时于三台运行器上执行 `scripts/ci.sh`：macOS 在 Mac mini 的常驻克隆里借用开发克隆 `~/Documents/GitHub/ElyOfficeSuite` 的引擎（`ELY_SHARE`；2026-10-11 起：从零构建 LibreOffice 超过 act_runner 默认的 3 小时，v0.1.3 的 Mac 任务被杀、无 dmg），Windows 在本机运行器上把 `engines` 与 `reference` 接到开发克隆，Linux 由同一台 Windows 运行器经 WSL 构建（服务器上的 Linux 运行器是一次性容器，建不了内核）；各自打包后上传到该标签的发布。Windows 为 NSIS 安装程序，Linux 为 AppImage、deb、rpm 与 Arch 包（引擎构建与打包都经 `packaging/linux/container.sh` 进 Ubuntu 26.04 容器，WSL 里须有 docker；`ELY_SHARE` 的目录一并挂进容器），都由 `packaging/stage.sh` 分装引擎；本提交的源码包只由 Linux 上传（`packaging/source.sh`；macOS 照建供 `release-macos.sh` 核对，不上传，两端并行时不重复；Windows 的检出把符号链接写成文件，不出）；重跑时所传文件有任一同名的已在发布里即失败、什么也不传，写明须先删去哪些（重建的字节不同，更新清单的散列会对不上已在的 dmg）；更新清单只含 macOS（Windows 与 Linux 的自动安装未做）。

 - 2026-10-11：Linux 标题栏按钮（核查 Windows 按钮问题时查出）。macOS 的红绿灯由系统画，不受影响；Linux 为客户端装饰，按钮由组件库画在标题栏的拖动区里，拖动区对任何按下都准备移动窗口，按住按钮时指针动一像素即开始移动窗口，合成器接管指针，松开到不了按钮，点击落空。组件库 3eb4d34：`drag_region` 只在按下未被里面的按钮认领（按钮以 `prevent_default` 认领）时才准备移动；`shell/title_tests.rs` 核对晃动的按下点得动 Linux 的关闭、标题栏空处照样移动窗口（去掉修复时前者失败）。未在真 Linux 桌面上点过。
