+# Agent Note: Web styling system — the token framework and engineering constraints
+
+Status: implemented
+
+> Token-system update (2026-07-22): the framework rulings here (CSS Modules + clsx, no component library, no tailwind, tokens-only colors) remain in force, but the two-layer `--bg-*`/`--text-*` token table and its `web-ui/src/style/global.css` home were replaced by the `--dsw-*` static+alias sheets in `packages/client/ui-theme/src/styles/` (dark = `body[data-ds-dark-theme]` override). Current authority: `missions/tasks/20260721-1520-web-plugin-rfc/architecture.md` §15.
+
+English | [中文](2026-07-19-web-styling-system.zh.md)
+
+> Division of labor: this RFC fixes the framework and constraints (rarely changes); [docs/web-styling.md](../../../../docs/web-styling.md) is the living spec (authoritative token values, the coding-rule checklist, the deviation record — it evolves with the implementation). Token changes and new rules go there; only changes to the framework itself come back here (overturning it requires a new RFC).
+
+## Problem
+
+The GUI has no designer supply; styles are written by an agent and reviewed. Without a machine-checkable token system and coding rules, colors/radii/motion drift as literals across components, and dark mode grows into conditional branches scattered inside components.
+
+## Decision
+
+| # | Decision | Content |
+|---|---|---|
+| 1 | **Visual baseline = Chat alignment** | Every value comes from the Chat front-end survey (brand blue `--accent: #3964fe`, gray scale, bubble/sidebar geometry, shadow tiers…); deviation is allowed but must be recorded in the web-styling.md deviation table |
+| 2 | **Two token layers, not three** | The baseline repo uses static→alias→specific three layers; at our size this compresses to "a semantic layer holding real values directly (comments cite the base palette source) + a handful of component-specific slots (`--bg-sidebar`/`--bubble-bg`)" — two layers, all living in `web-ui/src/style/global.css` |
+| 3 | **Font sizes/spacing are not tokenized** | Same decision as the baseline repo: font sizes are written in px inside components and **always paired with a line height** (16/24, 14/22, 12/18); spacing uses multiples of 4; tokenization covers only colors/radii/motion/font stacks/shadows |
+| 4 | **Borders and interaction states use the opacity scheme** | Borders `rgba(0,0,0,.04/.1)`, hover/active `rgba(38,49,72,.06/.1)` — they hold when layered on any elevation background, no new solid grays |
+| 5 | **Dark mode happens only in the token table** | `:root` holds light real values + `[data-theme='dark']` overrides the same-named variables; **component CSS has zero theme selectors**; when a non-token value genuinely must vary by theme, use the "CSS variable bridge" (the component defines a local variable, the theme block only overrides the variable) |
+
+## Engineering constraints
+
+- **CSS Modules + clsx, no component library, no tailwind**: each component has a same-named `.module.css` in the same directory; class names are camelCase, single-adjective state classes are attached via clsx; components pass `className` through.
+- **`composes` is banned**; `:global` only pierces third-party/cross-package class names and never defines new global classes; global utility classes live only in global.css and stay in the single digits (currently `.scrollable`).
+- **PostCSS plugins are currently zero** (vite has no postcss config; flat CSS suffices — adopting nested/custom-media requires recording it in web-styling.md first); CSS Modules type declarations use the wildcard declare in `css-modules.d.ts` (re-evaluate typed-css-modules per-file generation past 20 components).
+- **Dynamic styles go through the CSS variable bridge**: JS writes only variables (`style={{'--x': v}}`), rules stay in CSS; assembling style objects in TSX for theme/state branches is banned.
+- Transitions are always `var(--dur*) var(--ease)` and only transition opacity/transform/background-color/shadow; scroll containers uniformly use `.scrollable` (writing `::-webkit-scrollbar` inside components is banned).
+
+## The execution shape for agents
+
+The spec is maintained as a **review checklist** (web-styling.md §3, 12 items): each item is a decidable "see X, reject" — not a style suggestion — and writing styles and reviewing styles share the same table.
+
+Entry points for common tasks (operational checklists):
+
+- **Styling a new component**: same-named `.module.css` in the same directory, self-check against web-styling.md §3 item by item; colors/radii/motion reference only §1 tokens.
+- **Adding a token**: first add a row to the web-styling.md §1 table (light value + dark column + base palette source comment) → update both the global.css `:root` and `[data-theme='dark']` blocks → only then reference it in a component.
+- **Deviating from a visual-baseline constant** (the geometry/shadow values of web-styling.md §2): record a row in the §5 deviation table first (date/item/reason), then land the code.
+- **A non-token value that must vary by theme** (gradient endpoints and the like): the component defines a local CSS variable and the theme block only overrides the variable (the variable bridge); component CSS keeps zero `[data-theme]` selectors.
+
+## Division of labor with web-styling.md
+
+| Content | Home |
+|---|---|
+| The five framework rules, engineering constraints, why two layers / why font sizes are not tokenized | This RFC (changing it = a new superseding RFC) |
+| Per-token authoritative values (dark included), visual-baseline constants (sidebar/bubble/session-row/input-card geometry), the RPC four-quadrant direction-marker visual vocabulary, the 12 coding rules, the deviation record | web-styling.md (living document, evolves with the implementation) |
+| Value evidence (deepseekchat file:line) | The survey archive has served its purpose; git history keeps it |
+
+## Consequences
+
+Styles converge machine-checkably: colors/radii/motion/shadows reference only the §1 tokens of web-styling.md, dark mode is a single attribute-selector override table, and review runs off the same 12-item checklist the author self-checks against. The cost accepted: font sizes/spacing rely on the paired-line-height and multiples-of-4 disciplines rather than tokens, and any framework change requires a superseding RFC.
+
+## Alternatives considered
+
+| Rejected | One-line reason |
+|---|---|
+| Tokenizing font sizes/spacing | The baseline repo demonstrates convergence without it (the paired-line-height discipline substitutes); a bloated token table dilutes the authority of the color tokens |
+| Dark mode via `prefers-color-scheme` or in-component branches | Attribute-selector whole-table override keeps components oblivious; system preference can be layered onto the toggle later without touching the token mechanism |

+# RFC: Web 样式体系——token 框架与工程约束
+
+Status: implemented
+
+> token 体系更新（2026-07-22）：本文框架裁决（CSS Modules + clsx、无组件库、无 tailwind、组件只用 token）仍然生效，但两层 `--bg-*`/`--text-*` token 表及其宿主 `web-ui/src/style/global.css` 已被 `packages/client/ui-theme/src/styles/` 的 `--dsw-*` static+alias 双层表取代（暗色=`body[data-ds-dark-theme]` 覆写）。现行权威：`missions/tasks/20260721-1520-web-plugin-rfc/architecture.md` §15。
+
+[English](2026-07-19-web-styling-system.md) | 中文
+
+> 分工：本 RFC 定框架与约束（少变）；[docs/web-styling.md](../../../../docs/web-styling.md) 是活规范（token 权威值、编码规范打勾清单、偏离记录，随实现演进）。改 token/加规则去那边；动框架本身才回这里（推翻须新 RFC）。
+
+## Problem
+
+GUI 无设计师供给，样式由 agent 编写并 review；没有一套机器可对照的 token 体系与编码规范，颜色/圆角/动效会在组件间字面量漂移，暗色主题会长成组件内散落的条件分支。
+
+## Decision（框架五条）
+
+| # | 决策 | 内容 |
+|---|---|---|
+| 1 | **视觉基线 = Chat 对齐** | 取值全部来自对 Chat 前端调研（品牌蓝 `--accent: #3964fe`、灰阶、气泡/侧边栏几何、阴影分级……）；允许偏离但须在 web-styling.md 偏离表记录 |
+| 2 | **token 两层不三层** | 基线仓是 static→alias→specific 三层；我们体量下压成「语义层直接持实值（注释标 base 色板出处）+ 极少数组件专属槽位（`--bg-sidebar`/`--bubble-bg`）」两层，全部住 `web-ui/src/style/global.css` |
+| 3 | **字号/间距不 token 化** | 基线仓同款决策：字号在组件里写 px 且**成对写行高**（16/24、14/22、12/18），间距用 4 的倍数；token 化只覆盖颜色/圆角/动效/字体栈/阴影 |
+| 4 | **边框与交互态用透明度制** | 边框 `rgba(0,0,0,.04/.1)`、hover/active `rgba(38,49,72,.06/.1)`——叠加在任意海拔底色上都成立，不新造实色灰 |
+| 5 | **暗色只在 token 表做** | `:root` 亮色实值 + `[data-theme='dark']` 覆盖同名变量；**组件 CSS 零主题选择器**；确需按主题换非 token 值时用「CSS 变量桥」（组件定义局部变量、主题块只覆写变量） |
+
+## 工程约束
+
+- **CSS Modules + clsx，无组件库、无 tailwind**：每组件同目录同名 `.module.css`；类名 camelCase、状态类单形容词由 clsx 挂载；组件透传 `className`。
+- **禁 `composes`**；`:global` 仅穿透第三方/跨包类名，不定义新全局类；全局工具类只住 global.css 且个位数（现状 `.scrollable`）。
+- **PostCSS 插件现状为零**（vite 无 postcss 配置，平铺 CSS 即够用；引入 nested/custom-media 前需先记入 web-styling.md）；CSS Modules 类型声明用 `css-modules.d.ts` 通配 declare（组件数超 20 再评估 typed-css-modules 逐文件生成）。
+- **动态样式走 CSS 变量桥**：JS 只写变量（`style={{'--x': v}}`），规则留在 CSS；禁止 TSX 内拼样式对象做主题/状态分支。
+- 过渡一律 `var(--dur*) var(--ease)` 且只过渡 opacity/transform/背景色/阴影；滚动容器统一 `.scrollable`（组件内禁写 `::-webkit-scrollbar`）。
+
+## 给 agent 的执行形态
+
+规范以 **review 对照打勾清单**形态维护（web-styling.md §3，12 条）：每条是可判定的「见 X 即打回」，不是风格建议——写样式与 review 样式共用同一张表。
+
+常见事项的入口（操作清单）：
+
+- **写新组件样式**：同目录同名 `.module.css`，对照 web-styling.md §3 逐条自查；颜色/圆角/动效只引 §1 token。
+- **加一个 token**：先进 web-styling.md §1 表补一行（亮色值+暗色列+base 色板出处注释）→ global.css `:root` 与 `[data-theme='dark']` 两块同步 → 再在组件里引用。
+- **偏离视觉基线常数**（web-styling.md §2 的几何/阴影值）：先在 §5 偏离表记一行（日期/项/理由）再落码。
+- **需要按主题变化的非 token 值**（渐变端点等）：组件定义局部 CSS 变量、主题块只覆写变量（变量桥），组件 CSS 保持零 `[data-theme]` 选择器。
+
+## 与 web-styling.md 的分工
+
+| 内容 | 归属 |
+|---|---|
+| 框架五条、工程约束、为何两层/为何不 token 化字号 | 本 RFC（改=新 RFC 供替） |
+| token 逐项权威值（含暗色）、视觉基线常数（侧边栏/气泡/会话列/输入卡片几何）、RPC 四象限方向符视觉词汇、编码规范 12 条、偏离记录 | web-styling.md（活文档，随实现演进） |
+| 取值证据（deepseekchat file:line） | 调研归档已完成使命，git 历史留档 |
+
+## Consequences
+
+样式收敛到机器可对照：颜色/圆角/动效/阴影只引 web-styling.md §1 token，暗色是单一属性选择器覆盖表，review 与自查共用同一张 12 条清单。接受的代价：字号/间距靠成对行高与 4 倍数纪律而非 token；动框架本身须新 RFC 供替。
+
+## Alternatives considered
+
+| 放弃项 | 一句话理由 |
+|---|---|
+| 字号/间距 token 化 | 基线仓实证不 token 化也能收敛（成对写行高纪律替代）；token 表膨胀降低颜色 token 的权威性 |
+| 暗色用 `prefers-color-scheme` 或组件内分支 | 属性选择器整表覆盖让组件零感知；系统偏好可后续在 toggle 层适配，不动 token 机制 |

+# Agent Note: GUI testing system — the three-tier structure
+
+Status: implemented
+
+> Path update (2026-07-22, plugin-system refactor): the three-tier philosophy and golden-path method here remain current; homes moved — object-layer specs now live in `packages/client/runtime/tests/` (was web-runtime), wire specs in `packages/client/connection/tests/`, and the `web-ui` coverage exclusion is gone with the package (component specs are per-plugin jsdom suites under each `packages/client/*/tests/`). Current test-system authority: `missions/tasks/20260721-1520-web-plugin-rfc/architecture.md` §18.
+
+English | [中文](2026-07-20-gui-testing-system.zh.md)
+
+> Division of labor: this note covers only the test structure specific to the GUI (`packages/{client,host}/*` + `apps/web`); repo-wide testing policy (tiering principles, the with-key policy, real-implementation-first, REAL-composition) lives in [docs/testing.md](../../../../docs/testing.md) and is not restated here.
+
+## Problem
+
+The GUI stack spans multiple application shapes, and within one shape multiple runtime environments (the Node host, the data protocol layer, the browser object layer, React/DOM); a single-lane test suite cannot give a meaningful signal. Every link needs effective tests of its own, plus the base capability for full-chain testing.
+
+## Decision
+
+Cut along the architecture's natural test seams into three tiers, bottom-up:
+
+| Tier | Under test | Key technique | File location |
+|---|---|---|---|
+| 1 Protocol isomorphism | `AbstractApiClient` + `toFetchHandler` (bidirectional data / rpcId / zod types / SSE streams / batching / timeouts) | **The full chain at the isomorphic point**: `InProcessApiClient(toFetchHandler(脚本化 impl))` skips the network but genuinely runs the wire serialization — zero browser, pure node env | `packages/host/apiproxy/tests/client-handler.spec.ts` |
+| 2 Object-layer orchestration | `Session`/`SessionManager`/`ConnectionController` (state machines and timing: stitching / dedup / paging / optimistic draft clearing / pendingBuffers / reconnect / backoff) | **The "event sequence in → snapshot out" golden path**: programmable fakes + deferreds controlling timing + fake timers controlling backoff | `packages/client/web-runtime/tests/{session,manager,connection,…}.spec.ts` |
+| 3 Browser smoke | Build artifacts × a real browser (the page boots, one conversation round-trips) | Bare playwright library (chromium headless, no @playwright/test framework), minimal pass-through; fixture level + real-host level (self-skips without a key) | `apps/web/tests/smoke-{fixture,real}.e2e.ts` |
+
+Inter-tier discipline: **each tier tests its own layer, upper tiers never re-test lower ones** — smoke only proves the wiring is alive (the fixture level asserts zero `/api` requests and zero pageerror), interaction detail belongs to the verify scripts (see the lane map), wire semantics to tier 1, data semantics to tier 2. Pure-function layers (lineage/partial/notifier/fold-adapter) are tested directly with zero fakes in the same package's tests/ alongside tier 2.
+
+- **Host side** (apiproxy/runtime/webserver): under the repo-wide `test:coverage` gate, per-file 100%.
+- **Client side**: web-runtime **is already under the per-file 100% gate** (12 defensive unreachable arms carry reasoned `/* v8 ignore */` comments); the `vitest.config.ts` coverage.exclude is down to `packages/client/web-ui/src/**` (temporary — lifted progressively as component specs fill in after the component redo); tests still run, the exclusion only keeps web-ui src out of the thresholds. web-ui takes the **jsdom route (landed)**: jsdom + @testing-library/react entered root devDependencies (dev-only), first spec `web-ui/tests/utils.spec.tsx` (utils pure functions + component RTL render + hook uSES probe); the environment uses the per-file `// @vitest-environment jsdom` pragma, zero impact on the other node-env packages.
+- The exclusion is an **explicitly annotated ruling**, not a silent waiver; the lift path = delete the exclude line + add a justified exclusion or the missing tests.
+
+## Lane map
+
+| Scenario | Command | Content | When to run |
+|---|---|---|---|
+| Baseline | `pnpm run test:gui` | Tier 1+2 vitest (`packages/client packages/host`), seconds-fast, no browser, no server | Casually, after touching any GUI source |
+| Browser end-to-end | `pnpm run test:web` | Rebuilds the front-end dist first, then runs the tier-3 two-level smoke (fixture level + real-host level self-skip) | After touching the build surface/boot/carriage; before delivery |
+| Gate | `pnpm run test:coverage` | The repo-wide gate (host-side GUI packages included, client side excluded) | The PR window |
+
+**Division of labor between the verify scripts and vitest**: verify owns browser black-box regression (sequential steps = a user-operation script, one shared browser session, streaming PASS/FAIL output for the agent to locate the break), vitest owns first-class data-layer semantic assertions (reference stability `toBe`, state-machine timing, wire shapes). The two lanes complement each other, neither absorbs the other — scripts do not migrate to vitest (tearing apart an ordered script is a net loss); promoting one means wrapping a spawn shell hooked into the e2e lane, never rewriting the script body.
+
+## Anti-regression discipline
+
+- **Every bug fix pins an assertion**: a browser-visible bug is pinned into the regression section of its owning verify script (one pin = one report line); a data-layer bug is pinned into the matching spec (precedent: the res-close misjudgment pinned in the webserver bridge suite — pure Node, reproduces in seconds, no longer needs the 12s browser sentinel as the only defense).
+- **All-green on fixture is not done, the real host must pass too**: what the fixture short-circuits is exactly the wire carriage chain (node:http bridge close semantics, real network timing); both empirically confirmed bugs hid there. Changes touching connection/bridge/handler/SSE must run `verify-session-real`.
+- The code-on-disk-is-the-answer reconciliation workflow: when a behavior change lands and turns existing cases red, reconcile on the spot (fix the test or fix the code, with the RFC/contract as arbiter); no red left hanging.
+
+## Consequences
+
+Each lane tests its own tier: touching any GUI source gets seconds-fast `test:gui` feedback, wire/object-layer semantics assert in milliseconds in node env, and the browser carries only wiring-liveness smoke. On the gate surface, the host side is fully under per-file 100%; on the client side web-runtime is under the gate while web-ui waits behind the explicitly annotated exclude. The accepted cost: the inter-tier discipline (upper tiers never re-test lower ones) is upheld by review rather than a machine gate, and web-ui's coverage gap persists until component specs fill in after the component redo.
+
+## Alternatives considered
+
+| Rejected | One-line reason |
+|---|---|
+| Single e2e (everything through the browser) | Browser startup is seconds × N slower and timing is uncontrollable; wire/object-layer invariants can be fully asserted in milliseconds in node env |
+| Migrating the verify scripts to vitest | An ordered script shares one browser session; splitting the cases either formalizes it (sequential + shared page) or re-runs the preamble × N; streaming PASS/FAIL output is exactly the agent's locating interface |
+| Reusing FixtureApiClient in tests | The demo script runs on a real clock, tests need deferred hand-controlled timing — orthogonal purposes; forced reuse chains the tests to the demo's rhythm |
+| A standalone vitest config for GUI packages (once designed as vitest.gui.config.ts) | Package-level tests/ are already scanned by the root include; `vitest run packages/client packages/host` path filtering is the tight loop — zero new config |
+| Deferring hooks/component-layer unit tests (the original ruling) | Once deferred as "components are consumables, revisit after the redo"; overturned by the user on 2026-07-20 — **the jsdom mainline enters coverage** (no browser infrastructure in CI is the decisive reason, playwright demoted to a local enhancement), the RTL dependencies entered devDependencies, the first spec landed |

+# RFC: GUI 测试体系——三层结构
+
+Status: implemented
+
+> 路径更新（2026-07-22，插件体系重构）：本文三层理念与金路径方法仍为现行；家搬了——对象层 spec 现居 `packages/client/runtime/tests/`（原 web-runtime）、wire spec 现居 `packages/client/connection/tests/`，`web-ui` 覆盖豁免随包消亡（组件 spec 为各 `packages/client/*/tests/` 的 jsdom 套件）。测试体系现行权威：`missions/tasks/20260721-1520-web-plugin-rfc/architecture.md` §18。
+
+[English](2026-07-20-gui-testing-system.md) | 中文
+
+> 分工线：本篇只讲 GUI（`packages/{client,host}/*` + `apps/web`）特有的测试结构；全仓测试政策（分层原则、with-key 政策、真实体优先、REAL-composition）见 [docs/testing.md](../../../../docs/testing.md)，不在此复述。
+
+## Problem
+
+GUI 栈需要考虑多种应用形态，同应用形态内的不同运行环境（Node host、数据协议层、浏览器对象层、React/DOM），单一车道的测试给不了有效信号。需要对各环节都进行有效测试，并具备全链路测试的基础能力
+
+## Decision（三层结构）
+
+贴架构天然测试缝切三层，自底向上：
+
+| 层 | 被测物 | 关键手段 | 文件落点 |
+|---|---|---|---|
+| 1 协议同构层 | `AbstractApiClient` + `toFetchHandler`（双向数据/rpcId/ZOD类型/SSE 流/合批/超时） | **同构点全链**：`InProcessApiClient(toFetchHandler(脚本化 impl))` 不过网络但真跑 wire 序列化——零浏览器、纯 node env | `packages/host/apiproxy/tests/client-handler.spec.ts` |
+| 2 对象层编排 | `Session`/`SessionManager`/`ConnectionController`（状态机与时序：缝合/去重/翻页/乐观清稿/pendingBuffers/重连/退避） | **「事件序列进→快照出」黄金路径**：可编程假体 + deferred 控时序 + fake timers 控退避 | `packages/client/web-runtime/tests/{session,manager,connection,…}.spec.ts` |
+| 3 浏览器 smoke | 构建产物 × 真浏览器（页面起得来、一轮对话跑得通） | playwright 裸库（chromium headless，无 @playwright/test 框架）最简跑通；fixture 级 + 真 host 级（无 key self-skip） | `apps/web/tests/smoke-{fixture,real}.e2e.ts` |
+
+层间纪律：**下层各测各的，上层不重测下层**——smoke 只证接线活着（fixture 级断零 `/api` 请求、零 pageerror），交互细节归 verify 脚本（见车道地图），wire 语义归 1 层，数据语义归 2 层。纯函数层（lineage/partial/notifier/fold-adapter）随 2 层同包 tests/ 零假体直测。
+
+- **host 侧**（apiproxy/runtime/webserver）：进全仓 `test:coverage` 门禁，per-file 100%。
+- **client 侧**：web-runtime **已进 per-file 100% 门禁**（12 处防御性不可达臂带理由 `/* v8 ignore */` 注释）；`vitest.config.ts` coverage.exclude 只剩 `packages/client/web-ui/src/**`（暂时——组件重做后随组件 specs 铺满逐步解除），测试照跑，只是不拉 web-ui src 进阈值。web-ui 走 **jsdom 路线（已落地）**：jsdom + @testing-library/react 入 root devDeps（dev-only），首个 spec `web-ui/tests/utils.spec.tsx`（utils 纯函数 + 组件 RTL render + hook uSES 探针）；环境用 per-file `// @vitest-environment jsdom` pragma，node env 的其他包零影响。
+- 排除是**显式注释的裁决**不是静默豁免；解除路径=删 exclude 行 + 补 justified 排除或补测。
+
+## 车道地图
+
+| 场景 | 命令 | 内容 | 何时跑 |
+|---|---|---|---|
+| 基础 | `pnpm run test:gui` | 1+2 层 vitest（`packages/client packages/host`），秒级、无浏览器无 server | 改 GUI 任意源码后随手跑 |
+| 浏览器端到端 | `pnpm run test:web` | 先重建前端 dist，再跑 3 层双级 smoke（fixture 级 + 真 host 级 self-skip） | 改构建面/boot/承载后；交付前 |
+| 门禁 | `pnpm run test:coverage` | 全仓 gate（host 侧 GUI 包在内，client 侧 excluded） | PR 窗口 |
+
+**verify 脚本与 vitest 的分工**：verify 管浏览器黑盒回归（顺序步骤=用户操作剧本，共享一次浏览器会话，PASS/FAIL 流式输出供 agent 定位断点），vitest 管数据层语义一等断言（引用稳定性 `toBe`、状态机时序、wire 形）。两车道互补不收编——脚本不迁 vitest（拆散有序剧本是负收益），转正时包一层 spawn 壳挂 e2e 车道即可，脚本本体不改写。
+
+## 防回归纪律
+
+- **修一个 bug 钉一条断言**：浏览器可见的 bug 钉进所属 verify 脚本的回归节（一钉一行 report）；数据层 bug 钉进对应 spec（先例：res-close 误判钉在 webserver 桥 suite——纯 Node 秒级复现，不再需要 12s 浏览器哨兵作唯一防线）。
+- **fixture 全绿不算完，真 host 也要过**：fixture 短路的恰是 wire 承载链（node:http 桥 close 语义、真网络时序），两次实证 bug 都藏在那里。改动触及连接/桥/handler/SSE 的，`verify-session-real` 必跑。
+- 落盘代码即答案的对表工作流：行为改动落盘打红既有用例时，当场对表校准（改测试还是改代码以 RFC/契约为裁），不留悬红。
+
+## Consequences
+
+各车道各测各层：改任意 GUI 源码有秒级 `test:gui` 反馈，wire/对象层语义在 node env 毫秒级断言，浏览器只承担接线存活冒烟。门禁面上 host 侧全量进 per-file 100%；client 侧 web-runtime 已进门，web-ui 暂留显式注释的 exclude 之后。接受的代价：层间纪律（上层不重测下层）靠 review 而非机器门禁维持；web-ui 的覆盖缺口持续到组件重做后组件 specs 铺满为止。

+## Alternatives considered

+| 单一 e2e （全走浏览器） | 浏览器起步秒级×N 倍慢+时序不可控；wire/对象层不变量在 node env 可毫秒级全断言 |
+| verify 脚本迁 vitest | 有序剧本共享浏览器会话，拆 case 要么形式化（sequential+共享 page）要么重走前置×N；PASS/FAIL 流式输出正是 agent 定位接口 |
+| 测试复用 FixtureApiClient | 演示脚本走真实时钟，测试需要 deferred 手控时序——用途正交，硬复用把测试绑死在演示节奏上 |
+| GUI 包独立 vitest config（曾设计 vitest.gui.config.ts） | 包级 tests/ 本就被根 include 扫到，`vitest run packages/client packages/host` 路径过滤即窄循环——零新 config |
+| hooks/组件层暂缓单测（原裁决） | 曾以「组件是耗材、等重做后再议」暂缓；2026-07-20 用户改判——**jsdom 主线进覆盖率**（CI 无浏览器基建是决定性理由，playwright 降级为本地增强），RTL 依赖入 devDeps、首个 spec 已落 |
