-Models settings plugin: the provider configuration page and official-DeepSeek first-run routing overlay. It joins three wire domains into one shared snapshot — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time.
+Models settings plugin: the provider configuration page and official-DeepSeek conditional onboarding step. It joins three wire domains into one shared snapshot — `llm.providers` (the configurable-provider directory with each route's live/dormant state), `settings.describe` (serialized schemas, layered redacted values, secret slots), and `credentials.describe` (value-free configured/source/writable badges) — and renders provider rows with one editor card at a time.

 Rows are the *configured* providers (their profile resolves in the owning namespace); a whole-section provider whose key is not configured anywhere (the first-run DeepSeek posture) renders as its open setup card instead of a row, and the add flow is a card carrying the dormant-directory provider select — a bare-mounted `llm-pi-ai` offers its whole installed catalog before any route exists. The editor is a hand-written card per adapter family: the primary field is a single **API key** input — the page never asks for an environment-variable name; a typed key stores **write-only** through `credentials.set` under the profile's reference, deriving `<ROUTE>_API_KEY` when the profile has none, and the pi-ai profile records that derivation as `apiKeyEnv`, so `settings.yaml` never carries a key value. The collapsed 自定义设置 fold carries the curated extras — `baseURL` for both families (the deepseek placeholder shows the public endpoint), plus `reasoningEffort` (deepseek) or `reasoning` (pi-ai); every other profile field stays owned by `settings.yaml`. A row is deletable only when the user layer alone carries it (removal restores the composition base).

-The first-run overlay projects `deepseek-official` readiness from that same joined snapshot. A configured literal `apiKey` secret sidecar or configured credential reference suppresses the prompt, including a read-only launch-environment credential. A mounted adapter with a missing writable reference shows one action that opens Settings on the Models section, whose existing setup card exclusively owns key input and `credentials.set`; the overlay never holds a secret. An absent adapter is skipped because browser navigation cannot mount Cordis plugins, while an unusable settings or credential capability produces a deployment diagnostic with the same route to Models.
+The DeepSeek step projects `deepseek-official` readiness from that same joined snapshot after earlier onboarding steps complete. A configured literal `apiKey` secret sidecar or configured credential reference completes the step without rendering, including a read-only launch-environment credential. A mounted adapter with a missing writable reference shows one action that opens Settings on the Models section, whose existing setup card exclusively owns key input and `credentials.set`; the step never holds a secret. An absent adapter is skipped because browser navigation cannot mount Cordis plugins, while an unusable settings or credential capability produces a deployment diagnostic with the same route to Models.

 Every edit lands as `settings.mutate` path ops against the stored section — a set per changed field, an unset per cleared one, and a single unset for a deleted row. The page only ever holds the REDACTED descriptor, so it names the fields it can see rather than rebuilding a section: a stored literal secret it never received is mentioned by no op and survives. Each write carries the `revision` the card opened at, so a concurrent write from another tab or an external `settings.yaml` edit is refused as `settings-conflict` and the card asks the user to reopen instead of replaying its stale snapshot. The page refetches on the pushed invalidations (`settings/changed`, `credentials/changed`, `models/changed`, and `connection/reset`) once it has loaded, so an external `settings.yaml` edit, a second tab, or a settings-born route converges without polling.

-模型设置插件：提供方配置页和 DeepSeek 官方首次使用跳转浮层。它把三个协议领域汇聚为一个共享快照：`llm.providers`（可配置提供方目录，含每条路由的存活／休眠状态）、`settings.describe`（序列化 schema、分层脱敏值、secret 槽位）与 `credentials.describe`（不含值的 configured/source/writable 徽标）；页面据此渲染提供方行，一次只展开一张编辑卡片。
+模型设置插件：提供方配置页和按条件显示的 DeepSeek 官方首次使用引导步骤。它把三个协议领域汇聚为一个共享快照：`llm.providers`（可配置提供方目录，含每条路由的存活／休眠状态）、`settings.describe`（序列化 schema、分层脱敏值、secret 槽位）与 `credentials.describe`（不含值的 configured/source/writable 徽标）；页面据此渲染提供方行，一次只展开一张编辑卡片。

 行是*已配置*的提供方（其 profile 在所属 namespace 中解析得出）；密钥未在任何地方配置的整分节提供方（DeepSeek 的首次运行姿态）会渲染为其展开的设置卡片而非一行，「新增」流程则是一张承载休眠目录提供方选择框的卡片——裸挂载的 `llm-pi-ai` 在任何路由存在之前就能提供其完整的已安装 catalog。编辑器是每个适配器家族各一张的手写卡片：主字段是单独一个 **API 密钥**输入框——页面从不询问环境变量名；键入的密钥经 `credentials.set` 以**只写**方式存入 profile 的引用之下，profile 没有引用时便派生 `<ROUTE>_API_KEY`，pi-ai profile 会把这次派生记录为 `apiKeyEnv`，因此 `settings.yaml` 从不携带密钥值。收起的「自定义设置」折叠区承载精选的额外字段——两个家族都有 `baseURL`（deepseek 的占位符显示公共端点），另加 `reasoningEffort`（deepseek）或 `reasoning`（pi-ai）；其余每个 profile 字段仍归 `settings.yaml` 所有。只有当某行仅由用户层承载时它才可删除（删除会还原组合 base）。

-首次使用浮层从同一个联接快照得出 `deepseek-official` 的就绪状态。若 `apiKey` 字面量对应的 secret 槽位标记为已设置，或凭据引用已配置，浮层就不再显示，其中包括来自启动环境且只读的凭据。适配器已挂载、引用可写但尚未配置时，浮层只显示一个操作按钮，用于打开「设置」的 Models 分区；密钥输入和 `credentials.set` 仅由该分区已有的设置卡片负责，浮层绝不持有 secret。适配器缺失时直接跳过，因为浏览器导航无法挂载 Cordis 插件；设置或凭据能力不可用时则显示部署诊断，并提供同一个前往 Models 的入口。
+前序首次使用引导步骤完成后，DeepSeek 步骤会从同一个联接快照得出 `deepseek-official` 的就绪状态。若 `apiKey` 字面量对应的 secret 槽位标记为已设置，或凭据引用已配置，该步骤会直接完成而不渲染，其中包括来自启动环境且只读的凭据。适配器已挂载、引用可写但尚未配置时，该步骤只显示一个操作按钮，用于打开「设置」的 Models 分区；密钥输入和 `credentials.set` 仅由该分区已有的设置卡片负责，该步骤绝不持有 secret。适配器缺失时直接跳过，因为浏览器导航无法挂载 Cordis 插件；设置或凭据能力不可用时则显示部署诊断，并提供同一个前往 Models 的入口。

 每一次编辑都以 `settings.mutate` 的路径 op 落到已存分节上——每个变更字段一条 set、每个清空字段一条 unset、删除整行则是单独一条 unset。页面自始至终只持有**脱敏后**的 descriptor，因此它点名自己看得见的字段，而不是重建分节：一个它从未收到过的已存字面机密不会被任何 op 提及，也就得以留存。每次写入都携带该卡片打开时的 `revision`，因此来自另一个标签页或对 `settings.yaml` 的外部编辑所产生的并发写入会以 `settings-conflict` 被拒绝，卡片会请用户重新打开，而不是把自己的陈旧快照重放上去。页面加载完成后会在推送的失效事件（`settings/changed`、`credentials/changed`、`models/changed` 与 `connection/reset`）上重拉，因此外部的 `settings.yaml` 编辑、第二个标签页或 settings 新生的路由都无需轮询即可收敛。

+
+`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.

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 supplies onboarding registrants only two navigation facts: whether the session surface is the empty Hero and an `openSection(id)` callback that opens the panel on a registered section. Registrants own capability readiness, dismissal, copy, and mutations; the shell therefore does not become a second configuration fact source.
+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.
