Its existing request-time catalog lookup remains authoritative and still rejects unknown models with `UNKNOWN_MODEL`. `dsh-llm-deepseek` accepts an optional `models` config containing display entries, defaulting to `deepseek-v4-flash` and `deepseek-v4-pro`.

Type universes stay split at the aggregate level — `tsconfig.host.json` is the host program and `tsconfig.client.json` the client program, both referenced by the solution root `tsconfig.json` — because both sides merge cordis `Context` under the same keys (`sessions`, `loader`) with different services; client packages consume the wire vocabulary through pure type subpaths (`@deepseek-ai/dsh-session/types` and kin) so no host augmentation rides into the client program.

What makes a package a plugin? One rule: **a package is a plugin package once its consumption is cordis dependency injection; until then it is a plain package.** How code reaches the page is not part of the taxonomy — arrival follows from the kind instead of defining it.
- **Plain packages** are the absolute base the module system itself needs, plus libraries not yet converted to DI: the react family, cordis, `@deepseek-ai/dsh-client-modules` (the module system itself — it can never be a plugin, because modules precede all modules), the web shell kernel, and — for now — ui-slots, web-react, ui-primitives. Plain packages are shell-bundled, seeded into the module table, and invisible to the host graph.
- **Plugin packages** are everything else. Each one carries a `dshClient` manifest declaration (`{ platform, inject, immediately? }`) and one uniform shape: the shared tsdown preset emits `lib/client.js`, and `exports["./client"]` points at that bundle. Each is a governed entry of the host-authored graph. Nine exist today: connection, runtime, ui-theme, i18n, hmr (dev graphs only), ui-layout, ui-sidebar, ui-conversation, ui-trajectory.

Cooperation goes through cordis inject/services. `import type` is exempt; the type chain is untouched. This rule is why `scopeOf` is a `SessionsService` method and why `transportError` lives in `dsh-host-apiproxy`'s wire layer (its `RpcResult` home, inline-safe).
- **Plugin → plain package value imports are externals**, judged against the platform list. That list is one constant in the shell (`platform.ts`: react family, cordis, ui-slots, web-react, ui-primitives), imported by both the tsdown preset (for the external judgement) and `seed.ts` (for the table warm-up). One constant, two consumers — the hand-sync drift class stays dead.
- **The purity gate covers all nine plugin packages.** Its three branches: platform imports become externals; INLINE_SAFE wire layers are inlined; any other workspace leak is a build error.

All nine plugins share this one semantics; an `immediately` row reloads exactly like a lazy one.

Reloading connection or runtime cascades the whole UI — correct, if heavy.
The support boundary, stated honestly. Reload is coarse by design: fresh fiber, fresh components, React state lost, data layer untouched — react-refresh-grade state preservation conflicts with "re-executing the bundle re-runs the factory" and is deliberately out. Plain packages (react family, shell kernel, not-yet-promoted libraries) are not entries: changing them means a shell rebuild and a full page reload. No rollback in v1: an import failure leaves the entry fiberless and the next rebuilt frame retries from scratch; an apply failure leaves a FAILED fiber for the status projection; both log loudly. Self-reload works — the in-flight reload finishes in the old bundle's closure and the new apply opens a fresh SSE channel — but frames arriving in the gap are lost, and the next rebuild renotifies. One known dev-only race: a rebuilt frame overlapping a still-in-flight boot arrival shares that arrival's task and may materialize the pre-rebuild bytes; the next frame self-heals.

支持边界，如实陈述。重载粒度刻意做粗：全新 fiber、全新组件、React 状态丢失、数据层不动——react-refresh 级的状态保留与「重执行 bundle 即重跑工厂」相冲突，属刻意不做。普通包（react 家族、壳内核、尚未升格的库）不是 entry：改它们意味着壳重建加整页刷新。v1 不做回滚：import 失败让 entry 失去 fiber，下一个 rebuilt 帧从头重试；apply 失败留下 FAILED fiber 交给状态投影；两者都大声记录。自我重载可行——在途的重载在旧 bundle 的闭包里跑完，新的 apply 再开一条新 SSE 通道——但空窗期到达的帧会丢失，下次重建会再次通知。一处已知的仅限 dev 竞态：rebuilt 帧与仍在途的 boot 到达重叠时共享那次到达的任务，可能物化重建前的字节；下一帧自愈。

# Agent Note: Session model selection in the Web composer
Status: implemented
English | [中文](2026-07-24-web-session-model-selector.zh.md)
## Problem
The Web conversation displayed and sent through the Host's fixed provider/model route without exposing that route or letting a user change it. The TUI already had a session-local route target, but copying its presentation or hardcoding DeepSeek models in the browser would split model discovery and step-boundary semantics across front doors. A switch made while a response is running also needs one atomic boundary: prompt variables and request routing cannot observe different targets.
## Decision
The Web Host reuses `installAgentLlmTarget` for every created or resumed agent. The target starts from the latest `request/header` when the session has used a model, otherwise from the Host default. `session.selectModel` changes the session-local mutable target, and prompt assembly captures it with request routing; a switch during a running step therefore applies to the next assembled step. The next consumed route persists through the existing full `request/header` snapshot, while a choice that has not reached a request remains process-local.
The session RPC domain exposes `session.history`'s current `modelTarget`, a `session.models` directory, and `session.selectModel`. The directory is built dynamically from the LLM registry and grouped by provider. Provider catalogs load concurrently and fail independently, so successful groups remain usable alongside retryable failure records. Catalog membership stays advisory: the current model is inserted as an unlisted row when its registered provider omits it, and selecting an unlisted model under a registered provider remains valid.
The browser `Session` object owns the current target, grouped catalog, provider failures, operation error, and `idle`/`loading`/`ready`/`selecting`/`error` state. Selector mount primes the directory so the compact trigger can resolve a catalog name, and each menu open refreshes it. Directory and selection calls share a generation counter so older responses cannot replace a newer result; failures retain the previous current target and usable groups.
`@deepseek-ai/dsh-client-ui-conversation` declares the session-scoped single slot `conversation.composer.control` immediately before its primary button. `@deepseek-ai/dsh-client-ui-model-selector` occupies that slot only in an existing conversation. Its compact trigger and radio rows display the catalog name, falling back to the model id for an unlisted current target, while the upward menu displays provider headings once with keyboard navigation, dismissal, retry states, and current selection marking.
## Alternatives considered
**Use separate provider and model dropdowns.** The model list depends on the provider and repeats a two-stage interaction for every change. One grouped menu keeps the provider visible as organization without lengthening the trigger or each row.
**Hardcode the current DeepSeek catalog in the Web client.** This would drift from registered adapters and exclude deployment-owned providers. The LLM registry remains the source of provider and model metadata, including partial lookup failures.
**Make the selection a global default.** A global mutation would unexpectedly redirect other open conversations. The target belongs to one live session, while Host configuration remains the default for sessions without a logged request.
**Reject changes while an agent is running.** The shared atomic target already separates the assembled step from the next selection. Keeping the selector available lets the user prepare the following step without altering the in-flight request.
**Persist every click as a new session event.** A choice is not model-visible until prompt assembly consumes it. Persisting unused UI intent would add a durable event that does not reconstruct a model request; the existing `request/header` records the first request that actually uses the route.
## Consequences
An existing Web conversation can switch among dynamically discovered provider groups without displaying duplicated `provider/model` labels, and the current used route survives resume and reconnect. Catalog names remain presentation-only; selection and persistence continue to use provider/model ids. A provider catalog outage degrades only that group. Selection changes can reduce provider-side cache reuse when the route changes, but the selector adds no prompt content and does not disturb the in-flight step. The empty new-session composer still uses the Host default because it has no session identity or selector slot.
## Testing
Host tests pin grouped discovery, duplicate-catalog isolation, partial provider failure, logged restoration, unlisted current targets, unavailable-provider rejection, and next-assembly switching. Client tests pin state transitions, failure preservation, transport errors, stale-response fencing, history restoration, and snapshot reference stability. UI tests pin slot lifecycle, catalog-name labels with id fallback, provider grouping, radio semantics, retry/error states, successful and failed selection, outside dismissal, and Arrow/Home/End/Escape navigation. The keyless Web fixture exposes two provider groups and reports the selected route in the next generated response.

# Agent Note: Web 对话输入区的会话模型选择
Status: implemented
[English](2026-07-24-web-session-model-selector.md) | 中文
## 问题
Web 对话原本通过 Host 固定的提供方与模型路由显示并发送消息，既不呈现该路由，也不允许用户更改。TUI 已经具备会话级的路由目标，但如果照搬其呈现方式，或在浏览器中硬编码 DeepSeek 模型，就会让模型发现逻辑和步骤边界语义分散到不同前门中。响应运行期间发生的切换还需要一个原子边界：提示词变量与请求路由不能观测到不同的目标。
## 决策
Web Host 为每个新建或恢复的 agent（智能体）复用 `installAgentLlmTarget`。如果会话已经使用过模型，目标从最新的 `request/header` 开始；否则采用 Host 默认值。`session.selectModel` 会更改会话级可变目标，提示词组装则将该目标与请求路由一并捕获，因此运行中步骤发生的切换会应用于下一个组装步骤。下一条实际采用的路由通过现有的完整 `request/header` 快照持久化；尚未进入请求的选择则仅保存在当前进程中。
会话 RPC 领域公开 `session.history` 的当前 `modelTarget`、`session.models` 模型目录与 `session.selectModel`。该目录从 LLM（大语言模型）注册表动态构建，并按提供方分组。各提供方目录会并发加载，且彼此独立失败，因此成功加载的分组仍可与可重试的失败记录一同使用。模型是否位于目录仅供参考：如果当前模型的已注册提供方没有列出该模型，系统会将其作为未列出行插入；在已注册提供方下选择未列出的模型仍然有效。
浏览器中的 `Session` 对象持有当前目标、分组目录、提供方失败记录、操作错误，以及 `idle`、`loading`、`ready`、`selecting`、`error` 状态。选择器挂载时会预加载目录，使紧凑型触发器能够解析目录名称；此后每次打开菜单都会刷新目录。目录与选择调用共用一个代次计数器，防止较早响应覆盖较新结果；失败时保留先前的当前目标和可用分组。
`@deepseek-ai/dsh-client-ui-conversation` 在主按钮之前紧邻位置声明会话作用域的单实例 slot `conversation.composer.control`。`@deepseek-ai/dsh-client-ui-model-selector` 仅在已有对话中占用该 slot。其紧凑型触发器和单选菜单项显示目录名称；当前目标未列出时则回退到模型 ID。向上展开的菜单只显示一次提供方标题，同时提供键盘导航、关闭操作、重试状态和当前选择标记。
## 考虑过的替代方案
**分别使用提供方与模型下拉框。** 模型列表依赖提供方，每次更改都需要经过两阶段交互。单个分组菜单仍以提供方组织模型，同时不会增加触发器或各行的显示长度。
**在 Web 客户端中硬编码当前 DeepSeek 目录。** 该目录会与已注册适配器发生偏离，也会排除部署自有的提供方。LLM 注册表继续作为提供方与模型元数据的真源，也负责呈现部分查询失败。
**将选择设为全局默认值。** 全局变更会意外改道其他已打开的对话。目标仅属于一个实时会话；对于没有已记录请求的会话，Host 配置仍是默认值。
**agent 运行期间拒绝更改。** 共享原子目标已经将当前组装步骤与下一次选择分离。保持选择器可用，可以让用户为下一个步骤预先选择模型，而不会改变正在执行的请求。
**将每次点击作为新的会话事件持久化。** 只有提示词组装采用某项选择后，该选择才对模型可见。持久化尚未使用的 UI 意图，会增加一个无法重建模型请求的持久事件；现有 `request/header` 会记录首次实际使用该路由的请求。
## 影响
已有 Web 对话可以在动态发现的提供方分组之间切换，而无需显示重复的 `provider/model` 标签；当前实际使用的路由会在恢复和重连后保留。目录名称仅用于呈现；选择和持久化仍然使用提供方/模型 ID。某个提供方的目录不可用时，只有相应分组会降级。路由变更可能降低提供方侧的缓存复用率，但选择器不会添加任何提示词内容，也不会干扰正在执行的步骤。新的空会话输入区仍使用 Host 默认值，因为它没有会话标识或选择器 slot。
## 测试
Host 测试固定分组发现、重复目录项隔离、部分提供方失败、已记录目标恢复、当前未列出目标、不可用提供方拒绝，以及切换仅影响下一次组装。客户端测试固定状态转换、失败时保留原状态、传输错误、过时响应栅栏、从历史记录恢复，以及快照引用稳定性。UI 测试固定 slot 生命周期、显示目录名称并回退到 ID、提供方分组、单选语义、重试与错误状态、选择成功与失败、点击外部关闭，以及 Arrow/Home/End/Escape 键盘导航。无密钥 Web fixture（测试前置数据）公开两个提供方分组，并在下一条生成的响应中报告所选路由。

`SessionManager` retains the latest validated `session/title` control snapshot independently of list and session-instance arrival. Newer event seqs replace older snapshots, title timestamps contribute to list recency, and a subscription baseline discards any retained title beyond its `lastSeq` before the optional folded title arrives. Explicit session removal also clears the retained title. The client-facing `SessionSummary.title` is therefore only the actual durable title; `displayTitle` is always present and falls back through the cwd basename and session id. A cold persisted session keeps that fallback until opening or resuming it causes the host to fold and project its log-backed title.
## Session model selection
Each resident `Session` owns a `modelSelection` snapshot containing the current provider/model target, provider-grouped directory, provider-local failures, and the `idle`/`loading`/`ready`/`selecting`/`error` state. History establishes or refreshes the current target, opening a selector refreshes the directory, and selection failures preserve the last target and usable groups. Directory and selection operations share a monotonically increasing generation so an older response cannot overwrite a newer selection. A reconnect rebuild restores the target reported by the Host without replacing unchanged selection substructure.
## Model Experience
None, as the client runtime hosts browser-side services and the session object layer; nothing here reaches a model request.
None, as the session object layer selects the provider/model route used by a later Host request but adds no model-visible content.
#### KV Cache effect
None; this package neither assembles nor sends a provider request.
Changing the target can change or invalidate provider-side cache reuse; this package does not alter the prompt prefix itself.

Per-session UI state (selection, composer draft, active view) lives in the declared chat store (`stores.ts` `createChatStore`): apply constructs one handle and passes it to the conversation, chat-view, and details registrations, so the session slots share one instance per session (selection written by the chat view, read by details) and the framework owns instance lifecycle and draft persistence. Components are pure — the framework standard kit (`useSession`/`sessionId`/`useSessions`) and the store faces (`useStore`/`actions`) arrive automatically from the registration declaration; the inject factories contribute plain data and callbacks only (send/stop choreography, tab read face, details/paging callbacks, startSession chain).
The resident composer declares the session-scoped single slot `'conversation.composer.control'` and renders its occupant immediately before the send/stop button. Feature packages own the control and its state; ui-conversation supplies only the placement and standard slot shares. The new-session empty-state composer deliberately has no corresponding control slot.
`src/client/` is organized for the future package split: `contract/` is the sole inter-domain shared face (`slots.ts` slot declarations + composed slot props including the tool-row contract, `views.ts` shared primitives, `tool-call-model.ts`); the `skeleton/`, `chat/`, and `toolviews/` (sample registrants) domain directories import contract files and never each other; `apply.ts` is the only assembly point allowed to import all three domains. The `/client` export surface is the contract only — `apply`/`inject`, the two service classes, and the `contract/` type families; implementation components (skeleton, chat rows) and the store factory stay internal and reach the page exclusively through apply's slot registrations (tests take them via the `./src/*` subpath).

# @deepseek-ai/dsh-client-ui-model-selector
Session-scoped Web model selector. Its browser half occupies `conversation.composer.control`, shows the current catalog name beside the send button, and opens an upward provider-grouped menu. Provider names appear once as group headings; model rows and the trigger show catalog names without repeating the provider route, with the model id as the fallback for an unlisted current target.
The selector primes the advisory directory when it mounts so the trigger can resolve the catalog name, then refreshes it whenever the menu opens. The Session object layer owns loading, selection, partial-provider-failure, and stale-response state. A selection updates only that live session and takes effect at the next prompt-assembly boundary, including while the current step is running. The latest consumed target remains durable through the existing `request/header`; an unused choice is process-local.
Catalog membership is not request validation. The current target is included as an unlisted row when its registered provider omits it, while a target whose provider is unavailable remains visible on the trigger with a warning in the menu.
## Model Experience
None, as the browser selector changes subsequent request routing but adds no model-visible content.
#### KV Cache effect
Switching routes may invalidate provider-side cache reuse according to the selected adapter. The selector itself adds no prompt content.
## Known Limitations and Deferred Work
- **The new-session composer has no selector** — a session starts with the host default and exposes the selector after creation.
- **Unused selections are not durable** — reload restores the last route consumed by a request, not a choice made without sending.

The mux stream projects the latest log-backed title as a validated `session/title` control frame after each attached-session subscription baseline and immediately after the corresponding live raw title event. This projection does not add titles to `session.list`; cold sessions remain metadata-only there until opening or resuming attaches their logs.
Session model routing is a session-domain contract. `session.history` returns the selected `modelTarget`, `session.models` returns that target with provider-grouped advisory model metadata and provider-local lookup failures, and `session.selectModel` replaces the target selected for the next prompt-assembly boundary. Catalog membership is not validation: a registered provider may accept an unlisted model, while an unregistered provider returns `model-unavailable`.
## Carrier layer (`/client` + root)
`AbstractApiClient` holds every protocol invariant — rpcId minting, envelope wrap/unwrap, zod parsing, SSE frame decoding, unary timeout, microtask-batched envelope observation (`subscribeEnvelopes`) — while platform subclasses supply only the `doFetch` transport aspect. `InProcessApiClient` over `toFetchHandler(api)` is the isomorphic point: the full wire serialization/validation path with no network, used by `dsh -p` headless.

Unary methods take the narrow `RpcRequest<P>` and echo `request.rpcId`; a prompt's rpcId rides `MessageSource` into the `user/message` event so clients can promote optimistic echoes. `history`/`prompt` on a cold session implicitly resume it, deduplicating concurrent calls through an in-flight table; `history` paginates backwards on message boundaries (never mid-message). The mux stream replays a `session/subscribed` baseline per attached session and every still-pending question with its original rpcId. Question responses, including blank per-item answers, are validated against the owning session and exact request before an atomic first-wins claim; answer, whole-request cancellation, owner abort, and provider disposal broadcast `question/resolved`. The host stream carries session lifecycle, running flips, and `agent/error` as the only outlet for live failures with no turn position.
The Web front door installs the shared `installAgentLlmTarget` coupling for every created or resumed agent. A session starts from the latest logged `request/header` route when one exists, otherwise from the Host default. `session.models` discovers every registered provider concurrently, keeps successful groups when another provider fails, and inserts the current target as an unlisted row when its provider omits it. A selection changes the mutable session target immediately; prompt assembly snapshots it atomically with request routing, so a change during a running step first applies to the next assembled step.
## Model Experience
Indirectly, through the non-blocking first-message title request owned by [`dsh-session-title-llm`](../../session-title/session-title-llm/README.md) when `sessionTitleLlm` is enabled, the provider/model defaults injected into created and resumed agents, the other model-facing plugins `bootHost` mounts, and the logged [workspace-instruction prefix](../../context/workspace-context/README.md#prompt-shape) when `workspaceContext` is enabled.

The plugin registers the single provider route `deepseek`. A request selects it with `provider: deepseek`; its `model` is passed through as the wire `model` string, so changing DeepSeek models does not require lifecycle-time registration. Omitting `models` advertises `deepseek-v4-flash` and `deepseek-v4-pro`, each with a 128,000-token context window; an explicit list replaces those defaults, while `models: []` advertises none. Catalog entries are exposed through `ctx.llm.listModels('deepseek')` for clients such as ACP editors, but remain advisory: unlisted model ids still pass through unchanged. An omitted entry name defaults to its id.
The plugin registers the single provider route `deepseek`. A request selects it with `provider: deepseek`; its `model` is passed through as the wire `model` string, so changing DeepSeek models does not require lifecycle-time registration. Omitting `models` advertises `deepseek-v4-flash` as `DeepSeek-V4-Flash` and `deepseek-v4-pro` as `DeepSeek-V4-Pro`, each with a 256,000-token context window; an explicit list replaces those defaults, while `models: []` advertises none. Catalog entries are exposed through `ctx.llm.listModels('deepseek')` for clients such as ACP editors and the Web selector, but remain advisory: unlisted model ids still pass through unchanged. An omitted entry name defaults to its id.
`contextWindow` is optional per configured model and is not exposed through the advisory catalog. `ctx.llm.resolveModelContext('deepseek', model)` returns an exact model value first, then `defaultContextWindow` for an entry without capacity or an unlisted pass-through id. When neither value exists it returns `undefined` without invalidating routing. Pressure-sensitive plugins therefore get deployment-owned capacity without treating the model selector as authoritative. Registering another adapter for `deepseek` throws `LlmError('DUPLICATE_ADAPTER')`.
