 **Concurrent views converge without stale replacement.** The acknowledgement write omits `expectedRevision` deliberately: every tab writes the same version to one path, so the operation is idempotent and preserves sibling fields instead of rebuilding the section. `settings/document-updated` becomes `host/settings-changed`; an already mounted tab refetches and advances when another tab or an external editor commits the current version. The API proxy exposes this one product namespace through a closed allowlist beside configurable-provider namespaces, without treating its changes as model-catalog invalidations.
 
-**The welcome modal is scan-first and has one completion path.** Its hierarchy is a declaration title, one status sentence, one emphasized feedback callout, one consequence sentence, and a restrained quotation; the notice version changes whenever that authored copy changes materially. It renders no close icon or secondary action, installs no Escape handler, and assigns no click handler to the mask. Its mask starts below the 80 px top chrome and preserves `position:absolute`, zero left/right/bottom offsets, `rgba(0, 0, 0, 0.24)`, and `backdrop-filter: blur(2px)`. Continue is the sole button and receives initial focus.
+**Onboarding temporarily owns the viewport as one continuous stage.** A solid product surface replaces the complete application view through a body-level portal and marks the underlying app root inert; the exact required mask remains mounted behind that surface with `position:absolute`, zero left/right/bottom offsets, `top:80px`, `rgba(0, 0, 0, 0.24)`, and `backdrop-filter: blur(2px)`. Welcome and conditional credential setup render as successive pages in this stage instead of independent modals. Both pages reuse the Web UI's black `BrandWordmark`. The welcome page preserves the four authored paragraphs verbatim under the `内测声明` title; every paragraph uses one 16/28 body scale, and only the requested action clause inside the final paragraph receives a subtle 500 weight. A short staggered opacity/vertical entrance supplies pacing without blocking interaction and disappears under reduced motion. The title receives initial focus, Continue is the sole button, and no close, Escape, or mask-click path exists.

 **并发视图无需陈旧的整体替换即可收敛。** 确认写入有意省略 `expectedRevision`：每个标签页都向同一路径写入相同版本，因此该操作是幂等的，并会保留同级字段，而不是重建整个分节。`settings/document-updated` 会转为 `host/settings-changed`；另一个标签页或外部编辑器提交当前版本后，已挂载的标签页会重新拉取状态并推进。API 网关在可配置提供方 namespace 之外，通过封闭的允许列表暴露这一个产品 namespace，同时不会把它的变更视为模型目录失效事件。
 
-**欢迎模态窗口以便于扫读为先，且只有一条完成路径。** 其信息层级依次为声明标题、一句状态说明、一则重点突出的反馈提示、一句影响说明和一则克制的引语；只要这份文案发生实质变化，就同步提升通知版本。界面不渲染关闭图标或次要操作，不安装 Escape 处理器，也不为遮罩添加点击处理器。遮罩从顶部 80 px 的界面框架下方开始，并保留 `position:absolute`、left/right/bottom 偏移量为零、`rgba(0, 0, 0, 0.24)` 和 `backdrop-filter: blur(2px)`。「继续」是唯一按钮，并会获得初始焦点。
+**引导流程会暂时接管视口，形成一个连续阶段。** 纯色产品界面通过挂载到 `body` 的 portal 取代完整的应用视图，并将底层应用根节点标记为 inert；严格符合要求的遮罩仍挂载在该界面后方，并保留 `position:absolute`、left/right/bottom 偏移量为零、`top:80px`、`rgba(0, 0, 0, 0.24)` 和 `backdrop-filter: blur(2px)`。欢迎页和按条件显示的凭据设置页在这一阶段中依次呈现，而不是各自作为独立的模态窗口。两个页面都复用 Web UI 的黑色 `BrandWordmark`。欢迎页在 `内测声明` 标题下逐字保留既定的四段文案；所有段落统一采用 16/28 的正文字号与行高，只有最后一段中指定的行动语句使用较为克制的 500 字重。短暂的错落式透明度与纵向位移动画营造出舒缓节奏，但不会阻碍交互，并会在用户启用减少动态效果时禁用。初始焦点落在标题上，「继续」是唯一按钮，且不存在关闭、Escape 或点击遮罩的退出路径。

 Settings ownerless-copy and product-onboarding plugin: registers everything on the Settings surface that belongs to no single feature — the shell's trigger/header/close chrome content, the General section (Permission/Tool Call skeleton rows + the `settings.general.item` slot declaration), the `settings` dictionaries, and the first ordered welcome step. Feature-owned rows (Language, Appearance), sections (Models), and conditional onboarding steps stay with their feature packages.
 
-`src/onboarding-copy.ts` is the single editable owner of the complete Chinese and English notice plus `WELCOME_NOTICE_VERSION`. The Host half registers `ui-onboarding` in the user-settings seam; the browser compares `welcomeNoticeVersion` for exact equality and writes the current value only after Continue succeeds. The path mutation is idempotent across tabs and preserves sibling settings, while `host/settings-changed` makes an externally acknowledged notice advance without a reload. A different version deliberately presents the notice again. The welcome UI has no close, Escape, mask-click, or secondary path, and none of its copy or acknowledgement enters a Session log or model request.

-Settings shell plugin: a pure composition face. It occupies `sidebar.settings` with the trigger chrome and modal settings panel, and declares the slots registrants fill: `settings.trigger` / `settings.header` / `settings.close` (chrome content), `settings.section` (one page per feature), and `settings.onboarding` (ordered feature-owned steps on the empty Hero). The shell ships no copy and reads no locale state — all text arrives from registrants (ui-settings-general owns chrome, General, and the product welcome step; features own their sections, rows, and conditional onboarding steps).

-The shell projects the onboarding ledger into ascending order and mounts exactly one step at a time. The active registrant receives its id, `complete()`, and an `openSection(id)` callback; completing or skipping transfers ownership to the next entry. Registrants own durable completion, capability readiness, copy, and mutations, so two independently registered dialogs cannot stack and the shell does not become a second configuration fact source.
