Five new modules: apps/dsc (bin: parseArgs + node:http static server +
signal shutdown), packages/host/apiproxy (programmatic harness core
composition, agents:[]), packages/client/web-runtime (React-free browser
runtime), packages/client/web-ui (React mount), apps/web (vite build
entry producing dist consumed by apps/dsc via package exports).
Root wiring: apps/* workspace glob, dsh-* paths for host/client groups,
demo:web script, apps/web/dist gitignore. No protocol/API routes yet —
contract lands in step2 (see missions/tasks/20260719-1902-apiproxy-api-design).
Includes the design + implementation archives (spec v2.1, deepseekchat
baseline and harness boot research, implementation run log).
Acceptance: 12/12 passed incl. real-key llm.stream smoke (51 chunks).
feat(gui): apiproxy — four-quadrant RPC contract + fetch carriers, live end to end
Contract layer (src/api/, 14 files): four named wire message types
(ClientRequest / ServerResponse / ServerRequest / ClientResponse) as a
discriminated union over strict bidirectional rpcId (initiator mints,
responder echoes; channel and message fully decoupled — HTTP is the
client->server pipe, SSE the reverse); narrow RpcRequest<P>/
RpcResponse<T> signature forms; RpcMethodMap with RequestPayload<K>/
ResponseValue<K> derivation; typed RpcError details map; approval/
question responses modeled as ClientResponse via a single /api/respond
endpoint (RpcReceipt carrier ack); zod schemas anchored per Wire<T>
against exactOptionalPropertyTypes.
impl/api-proxy.ts: describe/list/create, both SSE streams (frame queue
pump, subscribed baseline, lifecycle frames, signal cleanup); history
pages on message boundaries (tail-back scan, partial included in the
tail page); prompt dispatches queue->agent.send / steer->agent.steer
with rpcId carried through MessageSource; cancel for attached sessions;
cold-session resume deduped via a per-id promise map; host-level
provider/model defaults injected at create/resume.
fetch/: mechanical UNARY_ROUTES table, two-level parse with
path==method check, SSE frames completed to ServerRequest full form;
client mints -> narrows -> envelopes outbound, verifies rpcId echo
inbound, streams SSE frames, four-quadrant onEnvelope tap (debug panel
choke point). Real-browser fixes: URL base resolves to location.origin
(hardcoded internal base broke real pages), browser-safe export paths.
Design archives: contract design.md v2.0 with decision log,
core-coverage audit, comparative studies, step2 impl run log. Probed
end to end over real HTTP: prompt -> live model stream -> history
returns the finished reply.
feat(gui): RpcLog debug panel — fixture-driven milestone, playwright-verified 10/10
web-runtime: rpcLog + ui slices (zustand), four-quadrant RpcLogEntry
(client-request / server-response / server-request / client-response),
onEnvelope tap -> microtask-batched pump with 500-entry ring buffer,
ConnectionController (private state, backoff reconnect), fixture API
with fake envelopes (?fixture switch), bootWebRuntime; contract types
via temporary local copies (api-types.ts, swapped for real imports when
W3 client lands).
web-ui: components/panels/RpcLog five-piece set (badge with unread
count, floating panel, direction glyphs per quadrant, same-rpcId
pair highlighting in two families, JSON payload expand, follow/pause,
clear), App shell, utils/formatRelative, light-theme CSS variables with
dark placeholders.
dsc bin: mime lookup fixed to use the actually-served file (naked
'/?query' no longer falls through to octet-stream download); shutdown
closes SSE keep-alive connections so SIGTERM actually exits.
Acceptance: scripts/verify-rpclog-panel.mjs (chromium headless) ALL
PASS 10/10 over design.md §D 1-6.
pkg: add web scripts for building
feat(gui): session milestone — list + conversation over Session OOP, styled RpcLog v2.1
web-runtime: Session/SessionManager object layer (resident instances,
mux frame routing, lineage flattening), foldSurface adapter with padding
sentinels for paged windows, chunk accumulator for streaming partials,
batched change notification (useSyncExternalStore contract), connection
sinks + reconnect fix (the 300ms self-abort reconnect storm that made
the session list flap is gone), fixture rewritten as a scripted host
(60-turn history, typewriter replay, resident pending approval, child
session); temporary contract copies deleted in favor of real apiproxy
imports.
web-ui: sessions screen (list with lineage indent + selection as
container-local state), conversation view (turn grouping, reasoning
fold, tool cards, steering, pending interaction cards, upward paging
with scroll anchoring), input bar with queue/steer/stop; RpcLog panel
restyled per docs/web-styling.md (tokenized palette, quadrant badge
glyphs now vertical ↑↓⇟⇞, pair highlighting, floating shadow).
docs/web-styling.md: living style guide (tokens, visual baseline,
coding rules, evolution log).
Acceptance: verify-session.mjs 31/31, verify-session-real.mjs 5/5
(real model streaming), verify-rpclog-panel.mjs 10/10.
feat(gui): hostruntime split + repo-wide package prefix rename
Package split (design: 20260720-0101-hostruntime-split-design):
dsh-host-runtime carries bootHost + createApiProxy + startHost()
(RunningHost {api, handler, defaults, ctx, dispose} — the seam Electron
and any future shell reuses; ctx is the official front-door mount
point); dsh-host-webserver carries the node:http static+API bridge
(fixed: abort now keys on res 'close' + writableEnded — req 'close'
fires on body end since Node 16 and was killing every SSE stream
instantly, the reconnect-storm root cause); apps/dsc is now a thin
assembly with web/-p subcommands. dsc -p runs the full isomorphic
carrier chain in process (second real protocol consumer; probed
end-to-end against the live model).
Naming rule (user decree): packages under host/ and client/ carry the
directory prefix in their npm name — dsh-host-apiproxy,
dsh-client-web-runtime, dsh-client-web-ui renamed repo-wide in one
frozen batch; explicit tsconfig paths entries added where the wildcard
no longer matches.
Acceptance: verify-session 31/31, verify-rpclog-panel 10/10,
verify-session-real 7/7 (incl. new 12s connection-stability sentinels),
tsc green, dsc web + dsc -p smoke both pass.
refactor(gui): AbstractApiClient class hierarchy — OO client with inheritable seams
AbstractApiClient (apiproxy) carries every protocol invariant: rpcId
minting, four-quadrant envelope wrap/unwrap, zod parsing, SSE frame
parsing, the payload-direct IApiClient surface (callers no longer mint
rpcIds — the carrier does), and the instance-level envelope observation
pump (batched via microtask; moved off module-level globals in
rpc-log.ts, which is now a pure subscriber mapping envelopes into store
entries — the debug panel observes the connection, it is not part of
it).
Platform subclasses own two abstract seams (doFetch, onEnvelope) plus
three protocol-level virtuals for transportless overrides:
InProcessApiClient (apiproxy; dsc -p uses new InProcessApiClient(
host.handler)), WebApiClient (web-runtime), FixtureApiClient (fixture
now subclasses instead of wrapping). Naming per decree: AbstractApiClient
/ IApiClient; ApiProxy stays the impl-side narrow-form contract.
headless.ts call sites drop rpcRequest wrappers (payload-direct);
split-design archive updated with the naming-rule ledger.
tsc green; verify-session 31/31, verify-rpclog-panel 10/10,
verify-session-real 7/7 (12s connection sentinel count=4); dsc -p smoke
CALLER-OK.
feat(gui): InputBar final form — bug batch, deepseekchat layout, single primary button, running locks input
Squashes the whole InputBar iteration batch: IME/caret/auto-grow/focus/dedup
bug fixes, layout aligned to the deepseekchat baseline, single primary button
with hover flyout, finalized button semantics with the Codex-style icon
circle, and running-state locking where stop is the only mid-turn action.
The same batch carried the Chinese-to-English code comment sweep
(density pruned), folded in here.
docs(gui): purge work-log references from code comments
76 design-doc references cleared across the GUI packages: section
pointers inlined as self-contained constraint statements, pure pointer
comments dropped, milestone codenames and ruling tags out, and the 14
contract file headers switched to the formal RFC (the only sanctioned
external reference). web-styling.md now cites the styling RFC instead
of the disposable research archive. grep for work-log reference
variants is clean across the GUI packages.
docs(gui): file-header comments self-contained — drop RFC filename references
RFC renames/reorgs must not require a source sweep (the 2026-07-20
two-way merge proved it). 11 headers lose only the '(RFC …)' tail and
stay self-contained; api-proxy.ts keeps its minimal-first note.
fix(gui): session streaming — freeze interrupted partials, sweep stale running calls, send force-scrolls
Aborted turns never emit the finalizing assistant/message, so the
accumulated partial and its running tool cards kept rendering below
later messages — the "new message lands above the stopped reply"
illusion. turn/end side effects now freeze content-bearing partials
into interrupted terminal nodes (fractional seq keeps flow order; the
live freeze and history replay converge through applyEventSideEffects,
so a refresh reconstructs identical frozen nodes) and turn running tool
cards into interrupted terminal cards; only content-free partials are
swept outright. ConversationView gains the send-force-scroll rule (own
words must be visible) alongside the pre-update atBottom follow flag.
Regressions pinned as E2-4a–c (real host) and §E1-11h (fixture).
feat(gui): webserver hardening verify script
feat(gui): dark-mode toggle pinned to the sidebar bottom
Interim home before the Settings page exists (the button re-homes with
zero logic change — mechanics live in utils/theme.ts): html[data-theme]
flip + dsc.theme localStorage, stored choice wins over the OS
prefers-color-scheme default, applied in mount() before first paint so
a dark reload never flashes light. Moon/sun inline SVG icon button at
the sidebar's pinned bottom row. Pure front-end local concern: no RPC,
no Session/store involvement. Dark sweep of list/conversation/input
card/RPC panel found no unreadable pairs — no token changes needed.
docs(gui): GUI RFCs and web styling handbook
Layering+RPC protocol and web client architecture RFCs (post-reorg,
developer-facing polish folded in) plus the styling engineering

feat(gui): session persistence surface — cold list, project cwd, legacy no-cwd retirement

docs(gui): doc-sync mechanical fixes — JSDoc on apiproxy/host exports, RFC sketch fences ignore-check, md-wrap paragraphs, drop missions links, web-ui plain-ts entry
chore(gui): module-graph regen + knip clean — drop dead re-exports, internalize createFixtureApi, scan web-ui tsx and verify mjs scripts
build(gui): wire client/host packages into the lib build shape — tsc references + tsdown (web-ui css-external), lib manifests, cordis peer, apiproxy typed subpaths, vite src aliases
test(gui): host-side per-file 100% coverage — apiproxy schema/carrier suites, webserver http-bridge suite, host-runtime composition suite; client/* coverage excluded pending the browser-side testing work item
docs(gui): package READMEs for the five GUI packages — model-experience audit entries, limitations sections
docs(gui): bilingual RFC pairs + client JSDoc completion — translate the three GUI RFCs to English with i18n records and manifest ratchet, Consequences sections both sides, full client/* export JSDoc, regen doc graphs and RFC index
fix(scripts): doc-typecheck built-declarations mode maps /src/* subpath wildcards (apiproxy browser-safe channels)
docs(gui): apply dsh rename across pr-gates docs — READMEs, layering RFC en, web-ui entry comment, i18n re-record
fix(gui): post-rebase lint reconciliation — wrap main-tree long doc comments, read-through narrowing guards, abortError Error normalization, handleUnary generic justification
fix(gui): post-rebase doc/test reconciliation — align host specs with evolved carrier contracts (sentinel rpcId, stream/error surfacing, url-path transport messages, defaults.cwd), Agent Note titles and relocated links, KV Cache effect sections, JSDoc on evolved exports
fix(gui): second-rebase reconciliation to 509db0cb3 — restore api panel exports the baseline suites consume, knip workspace entries for jsdom lane and apps/web smokes, hoist result narrowing, align testing.md to the narrowed web-ui exclusion
fix(test): vitest-scoped tsconfig maps bare imports for tsx specs — with GUI manifests now pointing at lib, an unmapped importer loaded a second copy of the web-runtime singletons
fix(gui): typecheck + lint clean over the tool-card batch — brand callIds and object-form turn/end reason in the view spec, narrow fixture arg stringification, wrap long v8-ignore comments
docs(gui): export JSDoc for tool-card surfaces + testing-note pairing header
docs: rfc for web testing
feat: add tools to host-runtime
fix(gui): dispatch agent/error via agentEvents in host-runtime spec — mounted invariants plugin rejects raw ctx.emit without the scope carrier
fix(gui): restore GUI knip workspaces + scripts/mjs entries and regenerate lockfile after master rebase
fix(gui): post-rebase gate repairs — drop context-node envelope (master unwrapped injected content envelopes), regen event matrix, condense testing.md web-ui exclusion within budget
fix(session): browser-safe deep-equal in surface — node:util import broke the vite bundle
ci(gates): frontend vite build joins pre-push — node: imports in the client closure pass tsc but break the browser bundle
test(tui): drop the checkout-dependent process.cwd() harness default — a long worktree path pushes the footer token counters past the 88-column fake terminal
test(gui): jsdom behavior E2E — conversation main path over fixture runtime, reconnect banner lifecycle
test(gui): jsdom RPC panel behavior — ledger rows, expand, pairing, pause/clear, follow-pause, payload truncation
test(gui): jsdom tier-2 — InputBar guards, reasoning fold, JSON blocks, message variants, theme, create-then-select; act-harden banner case
test(gui): jsdom tier-3 — ConversationView states/paging/force-bottom, ToolCallCard arms, PendingCard, list rows
test(gui): jsdom tails — view-card variants, LogRow directions, registry hygiene, badge overflow, hook ops, mount glue
test(gui): jsdom tails round 2 — call-ref blocks, resume follow, view precedence, failed create, empty-diff arm
test(gui): jsdom final arms — anchor compensation, follow-off, interval ticks, view halves, node-over-running precedence
test(gui): web-ui joins the per-file 100% coverage gate
Annotation-only src changes plus the config swap. The web-ui exclusion is
replaced by a single index.tsx entry (stale byte-identical duplicate of
mount.tsx, nothing imports it; same entry-glue treatment as bin.ts) and the
coverage include gains .tsx.
v8-ignore sites (each with its reason inline):
- ConversationView 3x ref-null guards; InputBar disabled-click guard
- ToolCallCard both-null arms + windowless-custom argsRaw arm
- LogRow css-module key fallbacks (start/stop block); RpcLogBody 3x ref-null guards
- web-runtime drift from the tool-card batch: fixture presenter catch/str
typo-guards, dense-array guards (fold-adapter reset, session rebuild,
fixture backscan), live view-present arm (fixture replays are text-only;
view vocabulary is covered by the history samples)
test(gui): close the PR #443 host-side coverage gaps — apiproxy client abort arms, api-proxy cold/view paths, webserver drain
- apiproxy fetch/client.ts: 3 new cases (pre-aborted signal short-circuits
before transport + string reason mapping, non-Error/string reason falls to
the default AbortError message, signal-less doFetch passthrough)
- runtime/api-proxy.ts: one v8-ignore (summarizeCold cwd arm — list()
filters cwd-less legacy metas) + api-proxy-cold.spec.ts (cold list merge:
mtime source, locate-undefined and vanished-log fallbacks, lineage;
no-persistence/no-factory resume → internal) + 2 view cases (history views
with meta passthrough and orphan/bad-args/presenterless soft-falls,
session/disposed open-call cleanup on the mux stream)
- webserver/index.ts: /api/big fixture drives both drain-wait legs (full
8MiB readback after drain, mid-chunk disconnect wakes via 'close')
feat: app shell
fix: rebase conflicts
fix: coverage
fix(gui): lint clean after rebase — wrap long v8-ignore comments, unconditional v1 detail-block claim
chore(gui): remove browser/probe verify scripts from scripts/
The six GUI acceptance/probe scripts (carrier-errors, rpclog-panel,
session, session-real, webserver-backpressure, webserver-hardening)
leave the repo's scripts/ tree; the three code comments that pointed at
them now describe the coverage lane without naming a script path.
fix(webserver): guard the request callback — one malformed request must not kill the process
The async handle() had no top-level catch, so any throw inside it (a bad
%-escape reaching decodeURIComponent, a client dropping mid-body, a
response stream erroring) became an unhandled rejection and took the whole
process down (audit R1 must-fix). The guard answers 400 when headers are
not out yet, destroys the socket when they are, and reports the failure to
onError (the package never prints). Spec covers all three legs: %-escape
barrage → 400 + server stays alive, non-Error throw wrapped for onError,
mid-stream explosion → socket teardown.

RFC: Web 客户端架构——client cordis 插件树、slot 体系与 React-free 对象层
Status: implemented
English | 中文
分工线:通道无关的分层模型与 RPC 协议(消息模型/类型体系/契约面/客户端基类)见 分层与 RPC 协议 RFC;本篇 = 浏览器侧:client cordis 树如何装载、UI 插件如何经 slot 与服务组合、React-free 对象层如何以不可变快照供给 React。
Problem
浏览器客户端受两股力塑形。其一是流式:事件驱动的对话 UI 里,若业务状态(事件窗口、流式累积、待答交互、连接状态机)散落在 React 组件与全局 store 中,每个 token 分片都会震荡渲染树,且换 UI 库等于重写业务逻辑。其二是模块化:UI 功能(布局、侧栏、对话、主题、语言包)必须是可独立装载的插件——按 host 下发的 manifest(元数据清单)在运行时组合,而非编译进单一 bundle——同时不放弃跨插件边界的编译期类型安全。
Decision
两端都跑 cordis。host 是一棵 cordis 插件树;浏览器里跑第二棵 client 侧 cordis 树,其中每一项 UI 能力都是插件,由壳静态持有的 loader 动态装载。树内 cordis ctx 承载一切运行时事实(服务、store、会话 scope),React 是纯投影:组件对框架零 import,一切经 props 注入,经 useSyncExternalStore(下称 uSES)订阅不可变快照。

每个 UI 插件同时是一个 host 插件(双入口包):node 半边住在 host 的插件树里,由 host Loader 管辖其生命周期;浏览器半边是 tsdown 闭包 bundle,挂在包的 exports["./client"] 下。host webserver 从带 dshClient manifest 字段的已加载插件推导启动清单,注入页面为 window.__DSH_BOOT__——HTML 到手即知要拉什么,零额外往返。
装载链全程:
GET /→ 壳启动,挂ctx.loader(loader 机件由壳静态持有——装载器不能经自己装载;其代码家在packages/client/runtime/src/client/loader/,壳经./loader子路径 import,避免壳 bundle 吞掉 runtime 包其余部分),把纯库实体(react、react-dom、cordis、ui-slots、web-react、ui-primitives)播种进 require 模块表,渲染一张不依赖任何插件的 loading 页。loader.start()读取__DSH_BOOT__。带immediately标记的条目构成先行装载组(connection、runtime、ui-theme、i18n):并行拉取、按组内inject拓扑序 apply,全组就位后才开始装载其余插件。其余插件随后按 inject 序装载。- 每个 bundle 执行
window.DSHClientProxy.loadPlugin({ id, factory })。loader 调factory(require)——bundle 是闭包工厂,external 依赖经注入的require到达,从模块表解析(无全局变量、无 import map;解析不到的标识符即刻大声失败)。factory 返回其模块导出面(含 cordisapply);loader 执行ctx.plugin(apply),随后以包名把该导出面登记进模块表——inject 拓扑保证后装插件可require先装插件。插件 CSS 内联在 bundle 里,注入为<style data-plugin="<id>">(CSS Modules 哈希 + 归属标记 = 隔离)。 await loader.settled()→ 壳从 loading 页一次切换到真 UI。单插件装载失败在 loading 页大声报错;不存在部分可用模式(渐进渲染为后置工作)。
双实例禁令:模块表包若被内联进插件 bundle,会复制运行时身份(两份 React、两套 store 注册表——一次真实白屏 P0 的根因)。tsdown client 预设在构建期把守纯度:模块表包的裸名 import 必须解析为 external(适用时改写为其 /client 形态),其余任何非 inline 安全 wire/类型层的 workspace 泄漏都令构建大声失败(packages/client/tsdown.client.ts,由 scripts/client-bundle-purity.spec.ts 钉住)。
dev 与 prod 同链:插件在 tsdown --watch 下重编译,刷新即重走同一条链;vite 只管壳(apps/web)。类型宇宙在聚合层拆分——根 tsconfig.json 是 host program,tsconfig.client.json 是 client program,因为两侧都在相同键(sessions、loader)上对 cordis Context 做声明合并且服务不同;client 包经纯类型子路径(@deepseek-ai/dsh-session/types 等)消费协议词汇,host 侧的声明合并不会搭车进入 client program。
slot 体系:页面怎么拼
页面是一棵坑位树;谁拥有区域谁声明坑位。契约只有一个家——@deepseek-ai/dsh-client-ui-slots 的 SlotMap 接口,经声明合并扩展。entry 只声明坑的轴与 owner 份额;注册方的注入 props 永不进全局表(「谁注入的放谁那里」):
declare module '@deepseek-ai/dsh-client-ui-slots' { interface SlotMap {
sidebar: { kind: 'single'; scope: 'root'; owner: SidebarOwnerProps }
conversation: { kind: 'single'; scope: 'session'; owner: ConvOwnerProps; children: 'conversation.empty' }
} }
ctx.slots.define('sidebar', { kind: 'single', scope: 'root' }) // declare=类型,define=落账
ctx.slots.register('sidebar', SidebarRoot, { inject: (b) => ({ /* ... */ }) })
- 三型:
single(重复注册即 throw)、list(id/order)、keyed(运行时按 key 分发,重 key 即 throw)。define 之前 register 即 throw。两 scope:root(无会话语境)与session——scope 决定下述注入形态。 - 组件全量 props 一律引用组合,不重抄:注册方组件声明
OwnerOf<K> & StandardOf<K> & OwnInjected——owner 份额从坑位 owner 的包引用、标配份额由框架供给(session 坑:useSession)、注册方自己的注入份额就地声明在组件旁。register<K, I>在调用点强制组合:组件形参位是SlotComponent<ComposedProps<K, NoInfer<I>>>(裸调用签名而非FC——FC 的propTypes静态位对标配份额产生反变噪音),I只从 inject 工厂返回值推断(NoInfer钉死),组件漂移或工厂不匹配都在注册点编译报错。ui-conversation 的注入份额住src/client/contract/slots.ts(ConversationInjected族),各骨架组件的 props 是一行引用组合。 - 转授=手写白名单+可选声明上限:owner 组件经自己的 props 拿到白名单收窄的
slots: ScopedSlots<'a' | 'b'>,调slots.renderSlot(key, props)渲染;把收窄子集递给子组件走narrowSlots(纯类型协变)。越权是编译错误,运行时白名单再兜住纯 JS 调用方。entry 可另声明children: <key>——register 校验组件白名单 ⊆ 声明上限(可选可见层,不强制)。每个被渲染的注册项都包在 per-entry 错误边界里:注册方崩溃(组件或 inject 工厂)只黑自己那一格,装配错误(缺 provider)则重抛——接错线的壳大声失败而不是静默降级。 - props 三源合并(出口组件来做;owner 只写第一份):① owner 供参(身份、展示参数、冻结切片)——按 entry 的 owner 份额强类型,renderSlot 点即精确;② scope 标配注入——session 坑自动获得绑定正确 Session 的
useSession;③ 注册方的inject工厂,session 坑 per-(注册项 × 会话) 调一次、root 坑 per-注册项调一次,以 WeakMap 缓存——切回会话时复用缓存结果。inject 工厂收到装配句柄(SessionBinding { sessionId, session, ctx }或RootBinding { ctx })——apply 世界的对象,永不进入 React。 - 两条供给通道收拢闭环:
RootBindingProvider(壳顶部挂一次)为 root 坑 inject 工厂供给 ctx;createSessionProvider(deps)构造唯一的会话 provider——依赖倒置(useCurrent/resolveBinding/renderBody),web-react 永不 import runtime。它订阅当前会话 id、解析引用恒等的 binding、以key={id}重挂其 body,并把 body 渲染委托给装配方的renderBody闭包(坑位所有权留在 layout;provider 不认识坑名)。
实现的家:注册表纯核在 packages/client/ui-slots(零依赖),出口组件/provider/uSES 桥在 packages/client/web-react。
服务与 scope 寻址
服务是插件对其他插件的唯一 API 面(UI 组件与注入面都不是 API;无人调用的插件不挂服务——ui-trajectory 即最小插件样板:无 ctx 服务,只 merge 视图表)。名册:ctx.connection(api client + 流句柄)、ctx.slots(注册表包装层,发 slots/changed)、ctx.sessions(列表 store、scope 树、binding)、ctx.loader、ctx.theme、ctx.i18n、ctx.layout(导航 + 面板观看态)、ctx.conversation(send/cancel/selection/views/startSession)、ctx.toolviews(具名按工具渲染注册表,带按会话 scope 过滤)。
SlotMap 之外还有两条同 declare-merge 惯例的类型化注册环:视图环(ConversationViewMap——entry 可声明 chromeProps/extraProps 扩展形状;ConvViewPropsOf<Id>/ChromePropsOf<Id> 组合基座+扩展,无声明的视图免费得基座,ui-trajectory 的两个 entry 带真 per-view props)与工具环(tool 名保持开放集——无全局键表;类型强化在 entry 内部:ToolViewProps.block 是 runtime 定义的真 ToolCallBlock union,register 同 slots 一样推断注册方注入份额)。
scope 寻址与 host 侧 agent scope 惯例同构:服务是 root 单例,方法不收 sessionId——它们读调用方 ctx 上的 scope 标(scopeOf(ctx))。在会话 scope 内,ctx.conversation.send('hi', 'queue') 自动打到该会话;跨会话调用换 ctx 定向(ctx.sessions.scope(id)!.conversation.send(...));从 root ctx 直接调 scoped 方法即 throw。client 会话 scope 的铸造方式与 host agent scope 相同(no-op 插件 fiber + scope 键 extend),首次观看时惰性建,只有会话被移除且无人观看才拆——仅 host 会话死亡不拆 scope(冻结为只读视窗)。
数据对象层(packages/client/runtime/src/client/sessions/)
帧从这里进、快照从这里出、fold 坐在中间——React-free(零 React import,grep 可断言):
mux/host 帧(ConnectionController 泵入,sinks 注入)
│
▼
SessionManager.handleMuxEnvelope / handleHostEnvelope
│ 带 sessionId 的帧只投已存在实例(审批/问答 requested 例外:进 pendingBuffers 缓冲)
▼
Session.handleMuxEnvelope ──► events 窗口(seq 连续升序)
│ │ 定稿事件 │ chunk
│ ▼ ▼
│ FoldAdapter PartialAccumulator
│ (→ nodes) (→ partial)
▼
Notifier 微任务合批 ──► ConversationSnapshot 缓存 ──uSES──► 组件
- Session(session.ts):懒建、常驻——建成后在后台持续吃帧,切走切回秒显。操作面:
prompt/cancel(RPC 透传;失败落进快照的promptError)、open(拉尾页 history,幂等)、loadOlder(向上翻页,防重入)、resync(重连 = 清窗口重跑 open)。订阅面:subscribe/getSnapshot(恒返缓存引用)——implements ObservableSnapshot<ConversationSnapshot>,构造时挂useSelector = bindSnapshotSelector(this),Session 本身就是 uSES 源。帧分发是一个 switch:session/event帧按 seq 去重(唯一去重键),open 在途时缓冲,否则追加 + 增量 fold;open/缝合按 seq 合并 live 缓冲并去重,subscribed.lastSeq超出窗口尾则回补一次。 - ConversationSnapshot(conversation.ts):不可变快照契约——
nodes(fold 产物,surface 序)、partial、runningCalls、pending、running、removed、openState、hasMore、promptError等。引用纪律(memo 与 uSES 的前提):顶层对象每变必新;nodes 数组重建但元素引用来自缓存;未变的子结构复用上一快照的引用。 - SessionManager(manager.ts):实例簇 + 帧总入口 + 会话列表。带 sessionId 的帧只投已存在实例(mux 广播不得把每个会话都实例化);例外是审批/问答
requested帧——它们不落 history、open 无法回补,故缓冲进pendingBuffers,实例化时回放。 - Notifier(notifier.ts):两条通知通道,按变更来源取用。
markDirty()(默认;帧驱动一律用它)按微任务合批——N 次变更、一次通知、一次重渲染;flush 先重建快照缓存再通知。notifyNow()(仅用户手势的直接回响)同 tick 重建并通知——受控输入的回响若延到微任务,DOM 会回滚、光标跳尾。帧驱动代码用 notifyNow 会让合批塌回逐帧渲染;禁。 - FoldAdapter / PartialAccumulator:fold 复用核心 SurfaceManager(
@deepseek-ai/dsh-session/surface),垫哨兵事件使 seq > 0 起头的分页窗口满足核心的seq === index断言;跨窗口 replace 时降级为容错线性扫描并置foldDegraded。分片完全不进 fold(O(1) 跳过):累积器把 StreamChunk 折叠成AssistantBlock[],一次增量只换该块引用;定稿消息到达即在同一批内弃掉累积器(提升无闪烁)。成本模型:一个分片 = 一次字符串拼接 + 一个脏标记;帧风暴下未订阅的 Session 只花那个标记。 - ConnectionController(在
packages/client/connection):开 mux/host 双流、for-await 泵入,代际围栏之内指数退避重连(500ms 翻倍至 10s 封顶、抖动、无限重试);sinks 单向注入(Controller 不认识 Session)。重连 = 重建:onConnected→ 列表刷新 + 各已打开会话 resync。对象层只面向IApiClient;Web 承载(HTTP POST 载两个 client→server 象限、SSE 载两个 server→client 象限)与客户端类族归分层 RFC 属地。
React 面(packages/client/web-react)
胶水包就是整条 ctx↔React 边界;组件保持零框架依赖。
createSnapshotStore<T>(init, opts):插件自有数据与壳观看态的 store 引擎——zustand vanilla + 草稿式更新,缺省flush: 'sync'(受控输入要求同 tick 回响),帧驱动 store 可选'raf'合批,可选整值 localStorage 持久化,dev 深冻结。Session 对象与快照 store 同构满足 React 消费的唯一数据契约:ObservableSnapshot<T>(getSnapshot/subscribe)。bindSnapshotSelector(source):把一个源绑定为经 uSES-with-selector 的带类型 selector hook。uSES 契约四条按构造成立:getSnapshot 恒返缓存引用;subscribe 是绑定期闭包(引用永稳);纯 CSR 不传 server snapshot;相等性缺省Object.is,按调用可选shallowEqual。useInvoke(fn):把异步动作包成引用恒定的触发器加 pending 标志;pending 走 per-hook 外部 store 经 uSES 读出(渲染路径零 setState),并发调用计数,invoke 引用永不变。- 相等性协议,全链一致:生产端结构共享;消费端以
Object.is或shallowEqual短路;React.memo浅比较。深比较全链禁止。
目录形态
十二个 packages/client/* 包(ui-slots、ui-primitives、web-react、connection、runtime、ui-layout、ui-sidebar、ui-conversation、ui-trajectory、ui-theme、i18n、web)加 apps/web——vite 应用,壳 boot 导出之上的薄 main。插件包的浏览器半边在 src/client/ 下;一切构建产物落 lib/——node 半边为 lib/index.js/lib/invariant.js,浏览器 bundle 为 lib/client.js(共享 tsdown client 预设两者皆出;无 dist/ 目录,exports["./client"] 指向 ./lib/client.js)。依赖方向:ui-slots ← web-react ← runtime ← ui-*(并列)← web,ui-primitives/ui-theme/i18n 为零依赖旁路。
多域插件包的 client 半边还按未来包边界再拆——ui-conversation 即样板:
src/client/
contract/ the only shared face between domains (types + composed props shares)
service.ts cross-domain orchestration (imports contract only)
skeleton/ domain: shell components (ConversationRoot/InputBar/EmptyState/DetailsPanel)
chat/ domain: the chat view
toolviews/ domain: the tool-row registry and samples
apply.ts the ONLY file allowed to import across domains (assembly point)
index.ts thin re-export shell (contract + apply + components)
域实现文件永不 import 兄弟域——共享面一律走 contract/(如 chat 经 ToolViewResolver 读面接口消费工具注册表,不碰注册表类)。scripts/verify-client-domain-graph.ts 把守分层(contract=0、域=1、apply/index=2;import 只准指向 ≤ 自己的层级;兄弟域边即失败)。将来拆包=每个域目录升格为包+机械改写 import 路径。
怎么开发
- 新 UI 功能 = 新插件包:package.json 声明
dshClient(+inject拓扑),浏览器半边写在src/client/(apply 挂服务/建 store、注册 slot 与 toolview),无 host 逻辑时 node 半边保持空 apply,用共享预设构建。把插件加进 host 配置;清单与装载随之自动跟上。 - 新 slot:契约合并进
SlotMap,owner 处define,经 owner 自己的ScopedSlots白名单渲染;注册方register,按需带 inject 工厂。永不全局导出组件。 - 消费新帧类型:带 sessionId → Session 分发 switch 加一个分支;host 级 → Manager 路由表;UI 需要时给
ConversationSnapshot加字段并守住引用纪律。 - 状态住哪:per-session 且要跨切换存续 → Session 对象 / scope 挂账 store;单视图私有(选中、滚动)→ 组件状态;壳观看态(导航、面板宽、偏好)→
ctx.layout的 store;业务数据 → 永远对象层,永不进观看态 store。 - 通知通道:帧驱动/异步 =
markDirty合批;受控输入需要同 tick 的用户手势直接回响 =notifyNow。
Consequences
token 流不再震荡渲染树:帧风暴对未订阅会话只花一个脏位,对被订阅视图每微任务一次合批重渲染(帧驱动 store 走 raf 合批)。UI 功能以独立插件的粒度装载、失败、停用——一个崩溃的 slot 注册项只黑一张卡,一个装载失败的 bundle 在 UI 切入之前大声报错。接受的代价:loader/模块表机件是团队端到端自持的定制基建;一次成型启动(无渐进渲染)用首屏粒度换装配简单;双类型 program 让「这个文件归哪个聚合」成为开发者偶尔要回答的问题。
Alternatives considered
| Rejected | One-line reason |
|---|---|
| 静态链接的单 SPA bundle | 插件必须由 host 在运行时按配置组合;单体把每个 UI 功能重新耦回一次构建 |
| window 全局变量 / import map 供共享依赖 | DI require 表让共享显式、大声失败、可替换;全局变量静默泄漏身份与版本 |
| 业务数据进 zustand 切片 | 事件窗口/累积器是行为状态机,不是扁平切片;对象层保住快照粒度与合批的可控性 |
| 工具行走字符串键的全局组件注册表 | 工具视图被多个视图共同消费且要按会话差异化——带 scope 过滤的具名服务(ctx.toolviews)才是诚实形态 |
| P-I 就做渐进/Suspense 启动 | 一次成型严格更简单;loader 的按插件状态面已保留,渐进点亮日后可落地而无需重构 |
