效果优先模型（sentence-model-desktop.safetensors，约 25 MB）不再随安装包分发， 改为和八股文模型一样在设置页下载后才能使用。 - engine：SentenceAssociationOptions 新增 neural_desktop_model 路径，留空即模型缺席、 静默不重排；词典不再从资源目录固定加载效果档。load_file 按 UTF-8 打开路径， 数据目录在非 ASCII 用户目录下也能读到模型 - server：新增 settings/neural_model，下载到 <数据目录>\models\neural-desktop\， 下载与导入都按 neural-model/lock.json 的字节数和 SHA256 校验后原子落位； 会话层只在开关打开时解析模型路径 - ui-html：设置页增加下载 / 导入 / 删除 / 浏览器下载，模型未就绪时开关置灰 - installer：不再打包效果档模型；旧版装进数据目录根下的那份在覆盖安装与卸载时清掉 原有配置项 sentence_neural_desktop 保持不变，用户的开关状态升级后保留。
WebView messages
messages.json owns the message envelope, payload shape, and allowed sender windows.
Change it here, run python3 generate.py, and re-sync the copy under ui-html/ in the same
commit. The generated TypeScript union and embedded C++ schema must pass generate.py --check.
runtime.js and validator.h implement the documented schema subset and run the same
fixtures.json compatibility cases. The standalone CMake test requires Boost.JSON;
the input engine itself does not acquire that dependency.
New messages carry protocolVersion: 1. A missing version is accepted as legacy v1
for existing skins; an explicit unknown version, unknown message, invalid payload,
or message sent from the wrong window is rejected before dispatch. This is envelope
validation, not a replacement for domain checks such as dictionary key validation,
allowed configuration values, or the host's HTTPS URL policy.
ui-html/scripts/sync-contracts.py materializes these bindings into
ui-html/webview2/shared and checks byte equality; CI runs it with --check, which
now compares against this directory directly rather than against a pinned submodule.
Settings imports the typed serializer and checks incoming messages. Classic candidate,
toolbar and menu pages load the same runtime from the host's https://msime-contracts/
virtual mapping; packaging must include webview2/shared.
Server-to-page candidate rendering currently uses the existing view functions; this contract covers WebMessage actions and settings responses. Candidate view model ownership is documented separately from transport envelopes.
