+# Agent Note: One carrier-level browser-trust boundary for the whole /api surface
+
+Status: implemented
+
+English | [中文](2026-07-28-api-browser-trust-boundary.zh.md)
+
+## Problem
+
+The web GUI host serves `/api` over plain HTTP (default `127.0.0.1:3080`, `--host 0.0.0.0` supported), and the surface includes remote-code-execution-grade methods — `session.prompt` drives an agent that runs bash. A browser turns the operator into a confused deputy against such a local API in two classic ways: a malicious page fires a "simple" cross-site POST (`text/plain` — sent without a CORS preflight) whose side effects execute even though the response stays unreadable, and a DNS-rebound origin talks to the socket as if same-origin, making CORS inapplicable entirely, with only the `Host` header betraying the attacker's domain. Before this decision the system's only browser-trust check (`isTrustedNativeDialogRequest`: loopback socket + same-origin + loopback Host) guarded exactly one cosmetic route — `host.pickDirectory`, whose native dialog pops on the host's screen — while every consequential method was unguarded. Guarding per-RPC also could not survive the upcoming in-app directory browser, whose whole point is serving legitimately remote clients that a loopback rule would refuse.
+
+## Decision
+
+Enforce browser trust once, at the carrier, for the entire `/api` prefix — two halves in two stacked PRs:
+
+- **Media-type fence (dsh-host-apiproxy)**: every `/api` POST must declare `application/json`, else 415 before parsing. Cross-site "simple" requests thereby stop existing: any cross-site attempt is forced into a CORS preflight this server never answers.
+- **Authority fence (dsh-client-connection, `src/api-request-trust.ts`)**: every request must present a `Host` that is loopback or matches a `trustedHosts` entry (exact on `host:port`, any port on port-less entries, WHATWG-normalized; rebinding defense). Deliberately no shortcut for unmarked requests: over plain HTTP a browser attaches neither `Origin` nor Fetch-Metadata to reads (EventSource, images, navigations — those headers go only to trustworthy destinations), so an unmarked request may be a rebound browser read whose response the page can read, and Host is the one header rebinding cannot forge; non-browser clients pass via loopback, the derived LAN IP literals, or a declared authority. An attached `Origin` must equal the Host authority; `sec-fetch-site: cross-site` is refused outright. A `trustedHosts` entry that is not a bare, canonical authority fails the plugin load — WHATWG parsing would otherwise quietly authorize the hostname inside a typo or broaden an exact-port grant. `host.pickDirectory` loses its bespoke guard and rides the same fence.
+
+Two boundaries stay deliberately out of scope: reachability is the webserver binding's policy (`host: 127.0.0.1 | 0.0.0.0`), and authentication for genuinely remote deployments is deferred work recorded in the connection README — the fence is a confused-deputy defense, not an auth layer. The old guard's loopback-socket check was dropped rather than generalized: with binding expressing reachability and `trustedHosts` naming remote authorities, the socket address adds nothing a header fence does not already cover.
+
+## Alternatives considered
+
+- **Per-RPC guards (status quo extended).** Rejected: the guard list trails the method list forever, the highest-value methods were already unguarded, and a loopback rule on browse RPCs would break the remote deployments they exist for.
+- **CORS headers + credential omission.** Rejected: we never want cross-origin reads at all, so answering preflights only widens the surface; refusing them is strictly stronger and simpler.
+- **Auth tokens now.** Rejected for this change: token minting/storage/rotation is real product surface; the fence closes the browser-deputy holes today without pre-deciding the auth design.
+
+## Consequences
+
+- Any future `/api` method is covered by construction; there is no per-route trust decision left to forget.
+- Non-loopback deployments must have their serving authorities trusted or requests are refused. The dsh CLI keeps its advertised `--host 0.0.0.0` LAN URL working by deriving the machine's LAN IP literals into the connection row (port-less entries — an IP-literal Host cannot be a rebound name, and the bound port may be OS-assigned) and offers `dsh web --trusted-host` for named authorities; compositions the CLI does not boot declare `trustedHosts` themselves. Non-browser automation rides the same fence: loopback, a derived LAN IP, or a declared authority passes; an undeclared DNS alias is refused.
+- Clients must label POST bodies `application/json` (ours always did; raw-fetch tests gained the header).
+- The trusted-network assumption of an unauthenticated `0.0.0.0` deployment is now documented instead of implicit.

+# Agent Note：整个 /api 面共用一道载体级浏览器信任边界
+
+状态：已实现
+
+[English](2026-07-28-api-browser-trust-boundary.md) | 中文
+
+## 问题
+
+Web GUI 宿主以纯 HTTP 提供 `/api`（默认 `127.0.0.1:3080`，支持 `--host 0.0.0.0`），而这个面上有远程代码执行级别的方法——`session.prompt` 驱动的 agent 可以运行 bash。浏览器会用两种经典方式把操作者变成攻击此类本地 API 的"混淆代理人"：恶意页面发出跨站"简单请求" POST（`text/plain`——不经 CORS 预检即发出），其副作用照常执行、只是响应不可读；以及 DNS rebinding 后的源以"同源"身份直连 socket，CORS 整体失效，只有 `Host` 头会暴露攻击者的域名。在本决策之前，系统里唯一的浏览器信任检查（`isTrustedNativeDialogRequest`：回环 socket + 同源 + 回环 Host）只守着一个装饰性的路由——`host.pickDirectory`，其原生对话框弹在宿主屏幕上——而所有真正要命的方法都在裸奔。按 RPC 逐个设防也活不过即将到来的应用内目录浏览器：它存在的意义就是服务合法的远程客户端，回环规则恰恰会拒绝它们。
+
+## 决策
+
+在载体层对整个 `/api` 前缀一次性执行浏览器信任检查——两半各占一个栈式 PR：
+
+- **媒体类型栅栏（dsh-host-apiproxy）**：每个 `/api` POST 必须声明 `application/json`，否则在解析前以 415 拒绝。跨站"简单请求"由此不复存在：任何跨站尝试都被逼进一次本服务器从不应答的 CORS 预检。
+- **权威栅栏（dsh-client-connection，`src/api-request-trust.ts`）**：每个请求的 `Host` 都必须是回环地址，或与某个 `trustedHosts` 条目匹配（带端口的 `host:port` 条目精确匹配，不带端口的条目匹配任意端口，均经 WHATWG 归一化；rebinding 防御）。刻意不为无标记请求开捷径：明文 HTTP 下浏览器的读取（EventSource、图片、导航——这些头只发给可信目标）既不带 `Origin` 也不带 Fetch-Metadata，因此无标记请求可能是被重绑页面发起且响应可被读走的读取，而 Host 是重绑唯一伪造不了的请求头；非浏览器客户端经由回环地址、推导的 LAN IP 字面量或已声明的权威通过。若带 `Origin` 则必须与 Host 权威完全一致；`sec-fetch-site: cross-site` 一律拒绝。不是纯的、规范形权威的 `trustedHosts` 条目会让插件加载失败——否则 WHATWG 解析会悄悄授权笔误里的 hostname，或放大精确端口授权。`host.pickDirectory` 失去专属守卫，与其他请求同栅而行。
+
+两条边界刻意留在范围之外：可达性归 webserver 绑定配置（`host: 127.0.0.1 | 0.0.0.0`）管辖；真正远程部署的认证是延期工作，记录在 connection README——这道栅栏是混淆代理人防御，不是认证层。旧守卫的回环 socket 检查被放弃而非泛化：绑定表达可达性、`trustedHosts` 点名远程权威之后，socket 地址提供不了头部栅栏覆盖不到的任何东西。
+
+## 曾考虑的替代方案
+
+- **按 RPC 设防（延续现状）。** 否决：守卫清单永远追着方法清单跑，价值最高的方法本来就没被守住，而 browse RPC 上的回环规则会破坏它们为之存在的远程部署。
+- **CORS 头 + 省略凭据。** 否决：我们根本不想要任何跨源读取，应答预检只会扩大暴露面；拒绝预检严格更强也更简单。
+- **现在就上认证令牌。** 在本变更中否决：令牌的签发/存储/轮换是真实的产品面；栅栏今天就能封死浏览器代理人漏洞，无需预先决定认证设计。
+
+## 后果
+
+- 未来任何 `/api` 方法天然在覆盖范围内；不存在会被遗忘的按路由信任决定。
+- 非回环部署的服务权威必须获得信任，否则请求会被拒绝。dsh CLI 通过把本机 LAN IP 字面量推导进 connection 行（不带端口的条目——IP 字面量 Host 不可能是被重绑的域名，且绑定端口可能由操作系统分配）来保住它广告出的 `--host 0.0.0.0` LAN URL，并提供 `dsh web --trusted-host` 声明具名权威；CLI 不参与引导的组合自行声明 `trustedHosts`。非浏览器自动化走同一道栅栏：回环地址、推导的 LAN IP 或已声明的权威可通过；未声明的 DNS 别名会被拒绝。
+- 客户端必须给 POST 体标注 `application/json`（我们自己的客户端一向如此；裸 fetch 测试补上了该头）。
+- 无认证 `0.0.0.0` 部署的"信任网络"假设从隐含变为成文。

+# Agent Note: Consolidated TUI presentation and navigation
+
+Status: implemented
+
+English | [中文](2026-07-28-consolidated-tui-presentation.zh.md)
+
+## Problem
+
+The terminal UI accumulated independent presentation rules that interacted poorly: palette roles aliased one another or inverted emphasis on light terminals; tool-card framing, output, and exit markers repeated or competed; injected context was parsed as XML and could not fold reliably; and `/resume` excluded sessions outside the current workspace even when the launcher could reach them. Each symptom appeared local, but the durable decision is one terminal-reading model: a small inspectable palette, status-led cards with recessed bodies, content-independent transcript folding, and workspace-aware navigation.
+
+## Decision
+
+### Palette
+
+`paletteSpec(scheme)` is the single table of SGR codes, close codes, and purposes. `createPalette` derives every wrapper from it and `/palette` prints the same table in the running terminal. Components do not emit their own SGR sequences except for the fixed startup brand gradient. Every close resets every SGR group its open sets.
+
+Duplicate roles are merged: `muted` into `dim`, `added` into `success`, `removed` into `error`, and the unused second accent is removed. `dim` uses `2;39` and closes with `22;39` on both schemes so recessed text stays relative to the terminal foreground rather than becoming a fixed heavy gray on light backgrounds. Colors and attributes are branded separately in TypeScript, allowing attribute/color composition while rejecting nested colors whose reset would discard the outer color.
+
+### Tool cards
+
+A tool card has one colored `Tool / <name>` status header over one dim body. Presenter titles, terminal commands and cwd rows, output, XML text, and fold markers use that body tone. Diff colors remain because red and green carry meaning, and signal markers remain errors.
+
+`renderUnknownXml` receives an explicit body styler for unknown tool results. Terminal presenters parse and remove the model-facing final exit or signal marker before returning `TerminalResultView.output`; the TUI renders the structured status once as its own pill. Truncation, timeout, and sandbox lines remain in the body because the pill does not represent them.
+
+### Injected context and folding
+
+Injected context renders as prose in `ContextCardComponent`, not through the XML tree renderer. Exact matched outer `<system-reminder>` lines are stripped, but mismatched, unpaired, or inline tag-like text remains verbatim. Model-facing content is unchanged. Folding uses the shared `preview` helper after body assembly, so it depends only on row count, never parser success or payload characters.
+
+`Ctrl+O` cycles collapsed, expanded, and hidden. Tool cards disappear in the hidden state together with their card-owned leading gap. Context cards participate in collapsed and expanded states but fall back to collapsed while tools are hidden, because injected instructions are not disposable tool traffic.
+
+### Cross-workspace resume
+
+The resume picker summarizes all records and owns a current-workspace/all-workspaces scope toggled with Tab. It defaults to the current workspace, adds workspace labels only in the broader scope, and refuses records without a cwd because there is no directory to enter.
+
+`TuiResumeHost.handoff` receives the selected `SessionId` and the cwd re-read during preflight. The CLI changes directory before disposing the current app, so an unreachable directory fails while the terminal can still recover; `execve` then inherits the selected workspace. The launcher also supplies the exit message rather than asking the TUI to reconstruct launcher syntax.
+
+## Alternatives considered
+
+**Keep separate notes and local fixes for each visual symptom.** Rejected: the decisions share one reading hierarchy and repeatedly superseded each other. One owner makes the final palette, card, context, and navigation rules clear without requiring readers to reconstruct chronology.
+
+**Keep aliases and enforce presentation by convention.** Rejected: aliases imply distinctions that do not exist, and nested color resets or incomplete SGR closes fail silently. A single table plus types makes the contract inspectable and mechanically checked.
+
+**Retain framing/output color splits inside tool cards.** Rejected: real cards mixed default foreground, cyan commands, dim cwd, unstyled XML, and dim output. The status header already provides the scan anchor; one recessed body removes noise. Diff colors are the narrow semantic exception.
+
+**Parse or repair injected context as XML.** Rejected: reminder frames are prompting conventions around arbitrary prose containing raw ampersands, comparisons, and placeholder angle brackets. Repairing or escaping it would either guess structure or alter model-visible text.
+
+**Hide context cards with tool cards.** Rejected: context carries injected instructions, not recoverable execution detail. The hidden phase therefore removes only tool traffic.
+
+**Keep resume restricted to one workspace or infer cwd after boot.** Rejected: the restriction forces manual relaunch, while restored header cwd does not control filesystem and shell resolution. The target directory must cross the host seam before process replacement.
+
+**Drop the TUI exit pill or remove model-facing exit markers.** Rejected: the pill is the scannable UI status, while the text marker is the model's status signal. The presenter consumes the marker when constructing the structured view so both audiences receive one representation.
+
+## Consequences
+
+The transcript reads as colored status headers over recessed detail, context presentation is stable for arbitrary prose, and one shortcut controls transcript density. The public `TuiTheme.muted` role is removed; extensions use `dim`. The palette and `renderUnknownXml` contracts are stricter, adding small compile-time friction in exchange for preventing silent style loss.
+
+Cross-workspace resume can move every path-resolving tool to another directory. A missing or inaccessible cwd prevents handoff. The broader picker also makes concurrent access to a shared session store easier to reach; cross-process session locking remains separate work.
+
+The terminal presenter still treats a final output line exactly matching its exit-marker grammar as structured status, so a command that intentionally prints such a line can lose it from the card body. This residual is documented by `dsh-tool-bash`.
+
+## Testing
+
+TUI unit and keyless terminal snapshots cover palette enumeration, light/dark roles, legal and illegal style composition, uniformly dim card bodies, semantic diff colors, marker-free terminal output with one exit pill, prose-preserving context frames, content-independent folding, the three-state Ctrl+O cycle, model filtering, and both resume scopes. CLI handoff tests cover passing the re-read cwd and rejecting directory-entry failure before teardown. Tool-bash tests pin result-marker emission, parse, and stripping as one round trip.

+# Agent Note: 统一的 TUI 呈现与导航
+
+Status: implemented
+
+[English](2026-07-28-consolidated-tui-presentation.md) | 中文
+
+## Problem
+
+终端 UI 逐步积累了多套彼此干扰的呈现规则：调色板角色互为别名，或在浅色终端中颠倒强调层级；工具卡片的框架、输出和退出标记重复或争夺注意力；注入上下文被当作 XML 解析，无法可靠折叠；`/resume` 即使能通过启动器访问其他工作区，也会排除不属于当前工作区的会话。每个症状看似局部，但持久决策只有一个终端阅读模型：精简且可检查的调色板、以状态为首且正文内收的卡片、与内容无关的记录折叠，以及感知工作区的导航。
+
+## Decision
+
+### 调色板
+
+`paletteSpec(scheme)` 是 SGR 开始码、结束码和用途的唯一表。`createPalette` 从该表派生所有包装器，`/palette` 在运行中的终端打印同一张表。除固定的启动品牌渐变外，组件不自行发出 SGR 序列。每个结束码都重置对应开始码设置的所有 SGR 组。
+
+重复角色被合并：`muted` 并入 `dim`，`added` 并入 `success`，`removed` 并入 `error`，未使用的第二强调色被移除。`dim` 在两种配色方案中都使用 `2;39`，并以 `22;39` 结束，使内收文本相对于终端前景色变暗，而不会在浅色背景上变成固定的深灰色。TypeScript 分别标记颜色和属性，允许属性与颜色组合，同时拒绝会因重置而丢失外层颜色的嵌套颜色。
+
+### 工具卡片
+
+工具卡片由一行带颜色的 `Tool / <name>` 状态标题和一块统一的 dim 正文组成。呈现器标题、终端命令及 cwd 行、输出、XML 文本和折叠标记都使用正文色调。差异颜色继续保留，因为红绿承载语义；信号标记也继续作为错误显示。
+
+`renderUnknownXml` 对未知工具结果显式接收正文样式器。终端呈现器在返回 `TerminalResultView.output` 前解析并移除面向模型的末尾退出或信号标记；TUI 只把结构化状态呈现一次。截断、超时和沙箱信息继续留在正文中，因为状态标记不表达这些事实。
+
+### 注入上下文与折叠
+
+注入上下文由 `ContextCardComponent` 按普通文本呈现，不经过 XML 树渲染器。仅移除精确配对的外层 `<system-reminder>` 行；不匹配、单边或正文内类似标签的文本都原样保留。面向模型的内容不变。折叠在正文组装完成后使用共享 `preview` 辅助函数，因此只取决于行数，不依赖解析是否成功或载荷包含哪些字符。
+
+`Ctrl+O` 在折叠、展开和隐藏之间循环。隐藏状态会连同卡片自有的前导间距一起移除工具卡片。上下文卡片参与折叠和展开状态，但工具隐藏时回到折叠状态，因为注入指令不是可丢弃的工具流量。
+
+### 跨工作区恢复
+
+恢复选择器汇总所有记录，并维护可用 Tab 切换的当前工作区/所有工作区范围。默认范围是当前工作区；只有更宽范围才显示工作区标签。没有 cwd 的记录会被拒绝，因为没有可进入的目录。
+
+`TuiResumeHost.handoff` 接收选中的 `SessionId` 和预检时重新读取的 cwd。CLI 在释放当前应用前切换目录，因此无法访问的目录会在终端仍可恢复时失败；随后 `execve` 继承所选工作区。退出提示也由启动器提供，而不是让 TUI 反推启动器命令语法。
+
+## Alternatives considered
+
+**为每个视觉症状保留独立 Agent Note 和局部修复。** 否决：这些决策共享同一阅读层级，而且彼此多次取代。由一份记录统一拥有最终的调色板、卡片、上下文和导航规则，读者无需重建变更顺序。
+
+**保留别名，并依靠约定执行呈现规则。** 否决：别名暗示并不存在的差异；嵌套颜色重置或不完整的 SGR 结束会静默失败。单一表格加类型约束使契约可检查且可机械验证。
+
+**保留工具卡片内部的框架/输出颜色分层。** 否决：真实卡片会混用默认前景、青色命令、dim cwd、无样式 XML 和 dim 输出。状态标题已经提供扫描锚点；统一内收正文能消除噪声。差异颜色是狭窄的语义例外。
+
+**把注入上下文继续解析或修复成 XML。** 否决：提醒框架只是包裹任意普通文本的提示约定，其中会包含原始 `&`、比较表达式和尖括号占位符。修复或转义要么猜测结构，要么改变模型可见文本。
+
+**随工具卡片一起隐藏上下文卡片。** 否决：上下文承载注入指令，不是可恢复的执行细节。因此隐藏阶段只移除工具流量。
+
+**把恢复限制在一个工作区，或在启动后推断 cwd。** 否决：前者迫使用户手动重启；后者恢复的会话头 cwd 并不控制文件系统和 shell 的路径解析。目标目录必须在进程替换前跨过主机接口。
+
+**移除 TUI 退出状态标记，或移除面向模型的退出标记。** 否决：前者是便于扫描的 UI 状态，后者是模型的状态信号。呈现器在构造结构化视图时消费文本标记，使两类受众各看到一种表示。
+
+## Consequences
+
+记录现在表现为带颜色的状态标题和内收细节；上下文对任意普通文本都稳定呈现；一个快捷键控制记录密度。公共 `TuiTheme.muted` 角色被移除，扩展改用 `dim`。调色板和 `renderUnknownXml` 契约更严格，以少量编译期摩擦换取对静默样式丢失的防护。
+
+跨工作区恢复会把所有依赖路径解析的工具移动到另一个目录。cwd 缺失或不可访问时不能交接。更宽的选择范围也使共享会话存储的并发访问更容易触达；跨进程会话锁仍是独立后续工作。
+
+终端呈现器仍会把与退出标记语法完全一致的最后一行输出视为结构化状态，因此命令有意打印这种行时，卡片正文可能丢失该行。`dsh-tool-bash` 已记录这一残余限制。
+
+## Testing
+
+TUI 单元测试和无密钥终端快照覆盖调色板枚举、浅色/深色角色、合法与非法样式组合、统一 dim 卡片正文、保留语义的差异颜色、仅有一个退出状态且正文无标记、普通文本上下文框架、与内容无关的折叠、Ctrl+O 三态循环、模型过滤和两种恢复范围。CLI 交接测试覆盖传递重新读取的 cwd，并在释放前拒绝目录切换失败。tool-bash 测试把结果标记的生成、解析和移除固定为同一轮往返契约。

+# client/ — web-GUI browser half
+
+English | [中文](README.zh.md)
+
+The browser side of the dsh web GUI: shell kernel, module system, wire consumer, React-free object services, the slot system, and the `ui-*` feature-plugin roster. Authoring rules live in [AGENTS.md](AGENTS.md); the host half is [`host/`](../host/README.md). All **product** packages, named `@deepseek-ai/dsh-client-<name>`.
+
+| Package | Role | ctx key / slot |
+|---|---|---|
+| `web/` | Shell kernel: `AppWebEntry` runs the two-stage boot over the host-pushed entry graph | (boots the tree) |
+| `modules/` | Client module system: browser peer of Node's ESM loader as a lazy CJS table under the vendored cordis Loader | (module face) |
+| `web-react/` | Shell-side React glue: `createSlotRenderer` + `SessionProvider` render seats | (renderer install) |
+| `connection/` | Wire consumer both ends: browser `ctx.connection` (shared api client + stream loop) and the node half mounting the `/api` route with its browser-trust fence | `ctx.connection` |
+| `runtime/` | Client cordis boot and React-free object services: slots, Sessions, Workspaces, per-session bindings | `ctx.slots` `ctx.sessions` `ctx.workspaces` |
+| `hmr/` | Dev-only hot reload for fetch-arrival client plugins (`--dev` graphs) | (dev entry) |
+| `locale/` | Browser locale preference (`zh`/`en`) plus the ns×locale dictionary registry | `ctx.locale` |
+| `ui-slots/` | Slot registry pure core: SlotMap merging, single `register` API, the four-share props family | (types + core) |
+| `ui-theme/` | Theme preference over the `--dsw-*` token stylesheets (`light`/`dark`/`system`) | `ctx.theme` |
+| `ui-primitives/` | Pure React atoms: icons, Button/Pill/Menu/Modal/Input, markdown family | (component library) |
+| `ui-layout/` | Shell three-column AppFrame; declares `sidebar` / `conversation` / `details` / `conversation.empty` | `ctx.layout` |
+| `ui-sidebar/` | Sidebar shell: Workspace/session rail, search, collapse; declares `sidebar.workspaces` | (slot host) |
+| `ui-workspace/` | Shared Workspace picker: browser region + hero picker over the same creation flow | (fills `sidebar.workspaces`, `conversation.hero.workspace`) |
+| `ui-conversation/` | Conversation domain: skeleton, chat view, input dock, per-tool row slots | (slot host) |
+| `ui-trajectory/` | Trajectory/Waterfall view tabs; the minimal pure-consumer plugin exemplar | (fills `conversation.view`) |
+| `ui-command/` | Command surface: session-keyed directory cache, `/` source, three-kind dispatch | `ctx.command` |
+| `ui-slash/` | Input trigger pipeline: `/` and `@` detection, grouped candidate menu, source roster | `ctx.slash` |
+| `ui-skill/` | `/`-trigger skill reference source over the `skill.list` RPC | (registers into `ctx.slash`) |
+| `ui-subagent/` | `@`-trigger subagent reference source over the sessions snapshot | (registers into `ctx.slash`) |
+| `ui-model/` | Model selection: `/model` popupSelect + the composer model seat over `ModelService` | `ctx.models` |
+| `ui-question/` | Web `ask_user_question`: host half mounts the tool, browser half fills the composer seat | (fills `conversation.composer`) |
+| `ui-settings/` | Settings shell: trigger chrome + modal panel; declares the `settings.*` slots | (slot host) |
+| `ui-settings-general/` | Settings ownerless copy: chrome content + General section skeleton | (fills `settings.*`) |
+| `ui-models/` | Models settings nav entry (content column lands in a later phase) | (fills `settings.section`) |
+
+Feature UI composes only through the slot system (`ctx.slots.register`) — the [slot system standard](../../.agents/notes/implemented/architecture/2026-07-22-slot-type-chain-implementation.md) is the definitive model; the [web client architecture note](../../.agents/notes/implemented/architecture/2026-07-19-gui-web-client-architecture.md) owns the loading chain and object layer.

 Wire consumer layer: the client plugin's apply mounts `ctx.connection` (shared api client + single-consumer stream-loop starter); the export face carries the wire contract types, the `AbstractApiClient` seam, and the loop's sink/config types. The platform subclasses (WebApiClient/FixtureApiClient), the ConnectionController loop, and the fixture data source are package-internal — apply selects and drives them; tests reach them via src. Contract: api-contracts v3 §3.
 
+## /api browser-trust fence
+
+The node half guards every request under `/api` before bridging (`src/api-request-trust.ts`). Every request — browser-marked or not — must present a `Host` that is a loopback authority or matches a `trustedHosts` entry: exact on `host:port` entries, any port on port-less entries, both sides compared through WHATWG normalization (DNS-rebinding defense). There is deliberately no shortcut for requests without browser markers: over plain HTTP a browser attaches neither `Origin` nor Fetch-Metadata to reads (EventSource, images, navigations — those headers go only to trustworthy destinations), so an unmarked request may still be a rebound browser read with a readable response, and Host is the one header rebinding cannot forge; non-browser clients pass the same fence via loopback, the CLI-derived LAN IP literals, or a declared authority. When markers are present, an attached `Origin` must equal the Host authority, and an explicit `sec-fetch-site: cross-site` marker is refused. A `trustedHosts` entry that is not a bare, canonical `host[:port]` authority — one WHATWG parsing reads back exactly as written — fails the plugin load loudly: parsing would otherwise quietly authorize the hostname inside `harness.internal/path`, or broaden a dangling-colon or zero-padded port to an any-port grant. Failures answer plain 403 before any RPC dispatch. A non-loopback (`--host 0.0.0.0`) deployment therefore needs its serving authorities trusted: the dsh CLI derives the machine's LAN IP literals itself and its `--trusted-host` flag declares named ones, so `trustedHosts` in cordis.yml is for compositions the CLI does not boot. The fence is deliberately not an authentication layer — reachability policy stays with the webserver binding, and auth remains deferred work. Decision record: [the api browser-trust boundary Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-api-browser-trust-boundary.md).

 ## Keyless fixture
 
 Any `fixture` query parameter selects the in-memory carrier. `fixture=empty` starts with no Workspace or Session; `fixturePrompt=reject` rejects prompts before acceptance; `fixtureAttach=fail` publishes a Session but rejects its Workspace attachment; `fixtureSessionCreate=drop-response` publishes and frames a Session before dropping the create response; and `fixtureFrames=workspace-first` reverses the default session-first create-frame order. Workspace creation by name/path and caller-preallocated SessionIds remain deterministic enough for assembled Web tests to reconcile list and frame arrival.

 协议消费层：客户端插件的 apply 会挂载 `ctx.connection`（共享 API 客户端 + 单消费方流循环启动器）；导出表层携带协议契约类型、`AbstractApiClient` seam，以及循环的 sink／配置类型。平台子类（WebApiClient/FixtureApiClient）、ConnectionController 循环和 fixture 数据源都属于包内部：apply 负责选择并驱动它们，测试则通过 src 访问。契约：api-contracts v3 §3。
 
+## /api 浏览器信任栅栏
+
+node 半侧在桥接前守卫 `/api` 下的每个请求（`src/api-request-trust.ts`）。每个请求——无论是否带浏览器标记——`Host` 都必须是回环地址权威，或与某个 `trustedHosts` 条目匹配：带端口的 `host:port` 条目精确匹配，不带端口的条目匹配任意端口，两侧均经 WHATWG 归一化后比较（DNS rebinding 防御）。刻意不为无浏览器标记的请求开捷径：明文 HTTP 下浏览器的读取（EventSource、图片、导航——这些头只发给可信目标）既不带 `Origin` 也不带 Fetch-Metadata，因此无标记请求仍可能是被重绑页面发起的、响应可被读走的读取，而 Host 是重绑唯一伪造不了的请求头；非浏览器客户端经由回环地址、CLI 推导的 LAN IP 字面量或已声明的权威通过同一道栅栏。当标记存在时，`Origin` 必须与 Host 权威完全一致；显式的 `sec-fetch-site: cross-site` 标记一律拒绝。不是纯的、规范形 `host[:port]` 权威的 `trustedHosts` 条目——即 WHATWG 解析读回后与原文不完全一致的——会让插件加载大声失败：否则解析会悄悄授权 `harness.internal/path` 这类笔误里的 hostname，或把悬空冒号、补零端口放大成任意端口授权。失败在任何 RPC 分发之前以纯 403 应答。因此非回环（`--host 0.0.0.0`）部署需要让自己的服务权威被信任：dsh CLI 会自行推导本机的 LAN IP 字面量，其 `--trusted-host` flag 用于声明具名权威，所以 cordis.yml 中的 `trustedHosts` 面向 CLI 不参与引导的组合。这道栅栏刻意不承担认证职责——可达性策略归 webserver 绑定配置，认证仍是延期工作。决策记录：[api 浏览器信任边界 Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-api-browser-trust-boundary.md)。
+
 ## 无密钥 fixture
 
 任何 `fixture` 查询参数都会选择内存载体。`fixture=empty` 启动时不含 Workspace 或 Session；`fixturePrompt=reject` 在接受前拒绝提示词；`fixtureAttach=fail` 发布 Session 但拒绝将其附加到 Workspace；`fixtureSessionCreate=drop-response` 在丢弃创建响应前发布 Session 并为其发出帧；`fixtureFrames=workspace-first` 则反转默认的 Session 优先创建帧顺序。按名称／路径创建 Workspace 以及由调用方预先分配 SessionId，均具有足够的确定性，组装后的 Web 测试可以据此协调列表与帧的到达。

+# host/ — web-GUI host half
+
+English | [中文](README.zh.md)
+
+The host side of the dsh web GUI: the API gateway every client shape shares, and the plain HTTP server it rides on. The browser side lives in [`client/`](../client/README.md); the composed application is [`apps/cli`](../../apps/cli/cordis.yml) serving [`apps/web`](../../apps/web/). All **product** packages.
+
+| Package | Role | ctx key |
+|---|---|---|
+| `apiproxy/` | The shared API gateway: the zero-Node TS wire contract (`src/api/`), the fetch carrier pair (`toFetchHandler` host-side, `AbstractApiClient` client-side), and the host implementation over `ctx.agents`/`ctx.workspace` | `ctx.apiProxy` |
+| `webserver/` | Plain HTTP route-registration carrier: `node:http` server listening on activation; routes register as named `exact`/`prefix` handlers | `ctx.httpServer` |
+
+`apiproxy` is transport-agnostic by design — it registers no routes; carriers wrap `ctx.apiProxy` themselves. The HTTP carrier route (with its `/api` browser-trust fence) is mounted by [`client/connection`](../client/connection/README.md)'s node half, which is why that package lives in the client group: it owns both ends of the wire.

Responses always echo the matching request's `rpcId` and never mint a new one. Method parameter/return structures live only in the domain interface signatures (`SessionsApi`, `HostApi`, `EventsApi`); `RpcMethodMap` registers the methods and every other position derives via `RequestPayload<K>`/`ResponseValue<K>`. Zod schemas anchor `satisfies z.ZodType<Wire<T>>` and parse at two levels: envelope first, business payload second, dispatched per method. Business errors ride `RpcResult`'s error branch (`RpcErrorDetailsMap` closes the code set); HTTP status expresses only the carrier.

 Workspace and Session lists are separate reconnect baselines. `workspace.create` creates a unique name or adopts an existing directory, `workspace.delete` removes only the Workspace registration, `session.create` accepts an optional preallocated Session id, and `host/workspace-changed`, `host/workspace-removed`, plus `host/session-added` carry committed increments in either arrival order. Registration deletion preserves the directory and session logs; its Sessions remain in `session.list` and become Ungrouped. `SessionSummary.blank` and the `host/session-added` frame carry the derived zero-events bit: clients hide blank sessions and reuse them per workspace, flip blank on the first `host/session-status(running:true)`, and treat `session.list` as the reconnect authority; cold summaries are never blank because lazy persistence keeps never-appended sessions out of `list()`.

-Plain HTTP route-registration plugin (default-exported `WebServerService`, config `{host, port, distIndex}`): a `node:http` server that listens on activation and provides `ctx.webServer` — `register(route)` adds a named `exact`/`prefix` route (duplicate `(kind, path)` throws: route patterns are a composition-level contract, so a collision is a misconfiguration; the returned disposer removes the route), `tapIndex(transform)` adds an index.html transform applied in registration order, and `port` reads the listening port (the OS-assigned value when `port` is 0).

+Plain HTTP route-registration plugin (default-exported `HttpServerService`, config `{host, port, distIndex}`): a `node:http` server that listens on activation and provides `ctx.httpServer` — `register(route)` adds a named `exact`/`prefix` route (duplicate `(kind, path)` throws: route patterns are a composition-level contract, so a collision is a misconfiguration; the returned disposer removes the route), `tapIndex(transform)` adds an index.html transform applied in registration order, and `port` reads the listening port (the OS-assigned value when `port` is 0). The match order is fixed — exact over the whole table, then longest prefix, then the static dist fallback with the locked semantics: traversal outside the dist root is 403, any miss falls back to `index.html` with HTTP 200 (SPA routing), unknown extensions ship as octet-stream, non-GET/HEAD is 405. Registration order carries no request-facing semantics.
 
 The package knows no harness concepts: the `/api` bridge is the connection plugin's route, plugin bundles and the HMR event stream are the modules/hmr plugins' routes. `host` accepts only `127.0.0.1` (default posture) and `0.0.0.0` (deliberate network exposure); `distIndex` is an assembly fact the composing app resolves and injects, never self-resolved (dist location is workspace knowledge of the app). Web (browser) shape only — Electron loads dist over `file://` and carries fetch over an IPC bridge, not this server. This package never prints; the URL line belongs to the shell.

 When optional `ctx.sessionReferences` is mounted, the same `@` menu also offers metadata-only session candidates, inserts `@[label](dsh-session:<payload>)`, and prepares the selected snapshots before dispatch. Session references remain structured because the model has no filesystem-like tool for retrieving session snapshots later. Preparation disables duplicate submission and restores the editor input on failure. The TUI chooses `agent.steer()` or `agent.followup()` from the status after that asynchronous preparation, so idle follow-ups still dispatch `agent/prompt-submit` while in-turn steering joins at a checkpoint without that hook.
 
-While the agent is running, ordinary editor submissions call `agent.steer()`; otherwise they call `agent.followup()`. A slash at the start of the submitted line enters `ctx.commands` instead: known commands execute directly, unknown commands produce a warning, and neither path automatically reaches the model. A command producer may explicitly schedule agent work; [`dsh-plan-mode`](../../plan/plan-mode/README.md#model-and-human-surfaces) uses that contract for `/plan [message]`. The TUI registers `/help`, `/model`, `/clear`, `/reasoning`, `/tools`, `/redraw`, `/reload`, `/resume`, `/status`, and `/exit` as agent-scoped definitions; every other effective command joins autocomplete and `/help` dynamically, as do `/skill:` completions. A status line above the editor reports the turn phase the TUI derives from session events — waiting for the first token, thinking, responding, or executing tools — with the elapsed time in that phase and the running step total, refreshed each second, and ends with the `Enter sends steering, Esc cancels` hint; while steering messages wait to reach the model it inserts a `N queued ·` badge before the hint that clears as each drains. Ctrl+C or Escape cancels a running turn. Tool cards collapse long bodies into a configurable head/tail preview; Ctrl+O toggles every card between its preview and full output. Ctrl+R toggles reasoning, Ctrl+L redraws, and Ctrl+D exits while idle.

An injected-context card renders its message as prose with the producer's outer reminder frame stripped, so neither the fold nor the frame stripping depends on the payload's syntax. Ctrl+R toggles reasoning, Ctrl+L redraws, and Ctrl+D exits while idle.
 
-`/model` opens the advisory `ctx.llm` catalog as a keyboard selector: Up/Down moves, Shift+Tab cycles the focused model's adapter-advertised reasoning efforts in display order, Enter selects the model and effort, and Escape closes it.

The selector renders the exact advertised effort list—including `off` when present—and does not synthesize, clamp, or transfer an effort between models. `/model <model>` still selects an unambiguous model id directly, while `/model <provider>/<model>` selects an exact target and uses its adapter default when one exists. The configured target or latest logged request header initializes the selector, and an unlisted current model remains visible because catalogs are advisory. Selection is local to this TUI session.

 `/reload` (EXPERIMENTAL, dev-only) re-reads every file-backed loader config tree and applies the diff to the running app — the HMR watcher's config path, invoked manually; it needs the cordis Loader in the context and degrades to a warning without one, runs only while the agent is idle, and refuses re-entry while a reload is in flight. Module-source hot reload remains watcher-owned. When a `skills` service is mounted, `/skill:<name> [instructions]` loads that skill's instructions into the conversation as a user turn; autocomplete lists the model-invocable skills, and any skill (including a model-disabled one) is loadable by its exact name.

Missing titles, models, cache input, or context capacity are labeled instead of inferred. The card is terminal-only and does not duplicate the compact footer.

The current session, a session already live in this runtime, an unreadable log, a mismatched cwd, or a session whose logged provider has no current adapter remains visible but disabled. Selection repeats those checks and requires the current agent to be idle before flushing the current session.

+`/resume` opens a full-viewport keyboard selector instead of a centered dialog. Two scopes cover the same candidate set: the current workspace, which it opens on, and all workspaces, which Tab toggles to. The scope line under the search field names the active scope and the count the other holds, and each row in the all-workspaces scope also reports its own workspace. Toggling clears the search and selection so the highlighted row always belongs to the visible list.

+Selection repeats those checks and requires the current agent to be idle before flushing the current session. The TUI then stops the terminal UI and calls the optional host-owned `TuiRuntime.handoffResume` with the selected id and the workspace re-read at preflight: process cwd, not the restored session header, is what filesystem and shell tools resolve against, so the host must enter that directory. Where `process.execve` is available, the shipped `dsh` host chdirs into it before disposing the app and replacing its process, and rejects an unreachable directory while the terminal can still be restored. Resume restores the same `SessionId`, transcript, title, todos, and durable goal; goal activation remains disarmed and the TUI asks for human confirmation or `/goal resume`.
+
+The exit line is launcher-owned, not configurable. A launcher provides `TUI_GOODBYE_MESSAGE_KEY` on the boot context — for the shipped `dsh`, the command that resumes this session — and exiting prints it verbatim after the terminal is released; absent, exiting prints nothing. Only the launcher knows how it was invoked, so only it can name a command that works. The TUI escapes terminal controls before rendering and never executes the text. A launcher that also supplies `MAIN_SESSION_ID_KEY` fixes which session the mounted app binds to, so resume survives any config-level patch.
+
+A launcher can seed a fresh session's first turn by providing `INITIAL_SKILL_KEY` (the skill name) on the boot context; the TUI auto-invokes it exactly as a typed `/skill:<name>`, once the chat is live. The shipped `dsh migrate`/`dsh upgrade` set it and only for a fresh session, so a resumed session never re-invokes the skill; an unknown name is reported as a notice.

 ## Color
 
-The palette uses the standard 16-color ANSI foregrounds and SGR attributes, which every terminal remaps to its active color scheme, so it stays readable on light and dark backgrounds alike. Body text keeps the terminal's default foreground rather than a fixed shade. Grouped regions (user prompts, assistant replies, tool cards) are separated by a bold, underlined role header in the role color and blank-line spacing rather than a filled block or a per-line prefix, so a mouse drag-select copies the message text without any leading bar or indent; a tool card's status (pending, error, success) shows in its colored, underlined title glyph and title. The question panel emphasizes its active row with bold accent text, while selectors use reverse video. These treatments are foreground-only, so they never collide with the terminal background. Set `color: false` to strip all styling.
+Every SGR code the TUI emits lives in one table, `paletteSpec` in `components/theme.ts`, which `createPalette` derives its wrappers from and `/palette` prints; no component writes an escape of its own. The table holds only the standard 16-color ANSI foregrounds and SGR attributes, which every terminal remaps to its active color scheme, so the TUI stays readable on light and dark backgrounds alike — the startup banner's brand gradient is the one deliberate exception. Body text keeps the terminal's default foreground rather than a fixed shade.
+
+There is one role per visual meaning: `dim` is the single recessed tone and `accent` the single emphasis color, while `success` and `error` double as a diff's added and removed lines. Colors and attributes are separately typed, so `bold(accent(x))` compiles and `accent(error(x))` does not — SGR has no color stack, so nesting one color inside another silently drops the outer color at the inner one's close. Attributes occupy independent SGR groups and compose with any color in either order. Run `/palette` to see every role as your terminal renders it, with its SGR pair.

Inside a tool card, the whole body — presenter title, a terminal `$` command and cwd, and the tool's own output — renders in one dim tone, so only the status-colored header carries color and the body reads as one recessed block instead of a run of competing shades; an injected-context card's prose is the same tone as its header.

+- **Resume has no cross-process session lock** — the selector rejects sessions known to be live in its own runtime, but another process can resume the same persisted id before or during handoff. The all-workspaces scope makes this reachable in one step, since a session another host is driving in a different directory is now selectable. Deployments that can run concurrent hosts must coordinate ownership outside the TUI.
 - **One configured session owns the transcript and editor** — questions from other agents can still use the shared overlay provider, but session rendering and prompt input remain bound to `sessionId`.
 - **Tool cards are text terminal presentations** — terminal, diff, and generic cards use tool-owned titles/content, but session content currently has no image block for inline image rendering.
 - **Non-TTY operation is intentionally unsupported** — app bundles that need automation must compose a one-shot or server front door (`dsh-cli-demo`, `dsh-acp`) rather than expecting an internal fallback.

+获得焦点的搜索字段紧跟搜索 glyph 开始，并发出 pi-tui 的 cursor marker，使终端 IME 组合保持锚定在字段内。候选项按最近记录的活动排序，可按日志支持的标题或会话 id 搜索，在所有工作区作用域中还可按工作区标签搜索；每行报告 current/live/persisted 状态、上一轮次结果、近期提供方／模型，以及存在时的持久目标阶段。Up/Down 与 Page Up/Page Down 导航，Enter 恢复，Escape 会先清除非空搜索，再次按下才取消，Ctrl+C 则直接取消。当前会话、已在本运行时中活跃的会话、不可读日志、没有可运行的已记录工作区的会话，或日志所记提供方没有当前适配器的会话仍会显示，但不可选择；不同于当前工作区的工作区属于作用域而非禁用原因，因为恢复会进入该目录。
+
+选择时会重复这些检查，并要求当前 agent 空闲，随后 flush 当前会话。TUI 接着停止终端 UI，并以所选 id 和在预检时重新读取的工作区调用由宿主持有的可选 `TuiRuntime.handoffResume`：文件系统与 shell 工具解析所依据的是进程 cwd，而非恢复出的会话头部，因此宿主必须进入该目录。存在 `process.execve` 时，发布的 `dsh` 宿主会先 chdir 进入该目录，再对 app 执行 dispose 并替换自身进程，并在终端仍可恢复时拒绝不可达的目录。恢复操作保留相同的 `SessionId`、transcript、标题、todo 和持久目标；目标激活仍保持解除，TUI 会要求用户确认或执行 `/goal resume`。
+
+退出时打印的行由启动器拥有，不可通过配置指定。启动器在启动上下文上提供 `TUI_GOODBYE_MESSAGE_KEY`（对于随附的 `dsh`，即恢复本会话的命令），释放终端后退出会原样打印它；未提供时退出不打印任何内容。只有启动器知道自己是如何被调用的，因此只有它能给出可用的命令。TUI 在渲染前会转义终端控制字符，且绝不执行该文本。若启动器同时提供 `MAIN_SESSION_ID_KEY`，则会固定已挂载应用绑定的会话，因此恢复功能不受配置层修补影响。
+
+启动器可通过在启动上下文上提供 `INITIAL_SKILL_KEY`（skill 名称）来播种全新会话的首轮；聊天就绪后，TUI 会像用户手动键入 `/skill:<name>` 一样自动调用它。随附的 `dsh migrate`/`dsh upgrade` 会设置该键，且仅对全新会话设置，因此恢复的会话绝不会重复调用该 skill；未知名称会以通知形式报告。

 ## 颜色
 
-Palette 使用标准 16 色 ANSI 前景色和 SGR 属性，每个终端都会将其重新映射到当前配色方案，因此浅色与深色背景下都保持可读。正文使用终端默认前景色，而非固定色调。成组区域（用户提示词、assistant 回复、工具卡片）通过以角色色渲染的粗体带下划线角色标题和空行分隔，而非填充背景块或逐行前缀，因此用鼠标框选复制时不会带上任何左侧竖条或缩进；工具卡片的状态（进行中、错误、成功）由其彩色带下划线的标题字形与标题体现。问题面板使用粗体强调色文本突出活跃行，选择器则使用反色。所有效果都只作用于前景色，因此不会与终端背景冲突。设置 `color: false` 可移除所有样式。
+TUI 发出的所有 SGR 代码都集中在一个表中，即 `components/theme.ts` 内的 `paletteSpec`；`createPalette` 从该表派生包装层，`/palette` 则打印该表，任何组件都不会自行写入转义序列。该表仅包含标准 16 色 ANSI 前景色和 SGR 属性；每个终端都会将它们重新映射到当前配色方案，因此 TUI 在浅色与深色背景下都保持可读——启动 banner 的品牌渐变是唯一一个有意保留的例外。正文使用终端默认前景色，而非固定色调。
+
+每种视觉语义只对应一个角色：`dim` 是唯一的弱化色调，`accent` 是唯一的强调色，`success` 和 `error` 还分别充当 diff 的新增行与删除行。颜色和属性分属不同类型，因此 `bold(accent(x))` 可以通过编译，`accent(error(x))` 则不行——SGR 没有颜色栈；在一种颜色内嵌套另一种颜色时，内层颜色闭合时会静默丢弃外层颜色。各属性占用彼此独立的 SGR 组，可以按任一顺序与任何颜色组合。运行 `/palette` 可查看每个角色在你的终端上的实际渲染效果及其 SGR 码对。

+成组区域（用户提示词、assistant 回复、工具卡片）通过以角色色渲染的粗体带下划线角色标题和空行分隔，而非填充背景块或逐行前缀，因此用鼠标框选复制时不会带上任何左侧竖条或缩进；工具卡片的状态（进行中、错误、成功）由其彩色带下划线的标题字形与标题体现。在工具卡片内部，整个正文——presenter 标题、终端 `$` 命令与 cwd，以及工具自身的输出——统一以同一种暗色渲染，因此只有带状态色的表头携带颜色，正文读作一个整体弱化的区块，而不是一串互相竞争的色调；注入上下文卡片的正文与其表头也是同一种色调。diff 卡片的 `+`/`-` 行与 `[signal …]` 标记保留颜色，因为那里的颜色本身就是语义，而非强调。问题面板使用粗体强调色文本突出活跃行，选择器则使用反色。所有效果都只作用于前景色，因此不会与终端背景冲突。设置 `color: false` 可移除所有样式。
