表不删除，但新会话模块不得 import 或访问它们。 + +### 1.2 共享 TypeScript 类型 + +共享类型放在 `lib/thread-chat/contracts/`，由 API、仓储和客户端共同引用；DB row 类型不得直接泄露给 React。核心定义如下： + +```ts +import type { UIMessage, UIMessageChunk, UITool } from "ai" + +export type MessageStatus = + | "generating" + | "completed" + | "stopped" + | "failed" + +export interface ThreadChatMessageMetadata { + messageId: string + threadId: string + modelId?: string +} + +export interface ThreadChatDataParts { + quote: { text: string } + "research-activity": WebResearchActivity + "research-route": ResearchRoute + "research-plan": ResearchPlan + "artifact-progress": MarkdownGenerationProgress +} + +export interface ThreadChatTools { + createMarkdownArtifact: UITool< + CreateMarkdownArtifactInput, + CreateMarkdownArtifactOutput + > + // 搜索/深读工具按现有实际 tool set 继续声明；禁止 unknown 后再手写强转。 +} + +export type ThreadChatUIMessage = UIMessage< + ThreadChatMessageMetadata, + ThreadChatDataParts, + ThreadChatTools +> +export type ThreadChatUIMessageChunk = UIMessageChunk< + ThreadChatMessageMetadata, + ThreadChatDataParts +> + +export interface ProjectDTO { /* id, titles, rootThreadId, archive/timestamps */ } +export interface ThreadDTO { /* topology, frozen context, titles, model */ } +export interface MessageDTO { + id: string + projectId: string + threadId: string + sequence: number + role: "user" | "assistant" + parts: ThreadChatUIMessage["parts"] + status: MessageStatus + modelId: string | null + replacesMessageId: string | null + supersededAt: string | null + feedback: "up" | "down" | null + error: { code: string; message: string } | null + createdAt: string + finishedAt: string | null +} +export interface ArtifactDTO { /* sourceMessageId + existing artifact fields */ } + +export interface ProjectBootstrapDTO { + project: ProjectDTO | null + threads: ThreadDTO[] + messages: MessageDTO[] // 含 superseded，但 selector 默认不显示 + artifacts: ArtifactDTO[] + activeGenerationIds: string[] +} +``` + +`ThreadChatDataParts` 的实际 key 必须由现有 Markdown Artifact 与 web research 契约逐项迁移；生成中 UI 可携带 `transient: true` 的 `artifact-progress`，持久化 checkpoint/finalize 前统一剥离 transient parts。用户消息以 text/file/data-quote parts 表达；system prompt 只在服务端通过 `instructions/system` 注入。 + +命令类型全部由 Zod v4 strict schema 派生：`StartProjectCommand`、`SendMessageCommand`、`ForkThreadCommand`、`EditLatestTurnCommand`、`RetryMessageCommand`、`StopMessageCommand`、`SetFeedbackCommand`、`RenameProjectCommand`、`SetProjectArchivedCommand`、`DeleteProjectCommand`。它们统一包含 `commandId`，创建类命令还包含客户端 UUID；响应统一为： + +```ts +type CommandResponse = + | { ok: true; replayed: boolean; data: T } + | { ok: false; error: ApiErrorDTO } + +interface GenerationAcceptedDTO { + project: ProjectDTO + thread: ThreadDTO + userMessage?: MessageDTO + assistantMessage: MessageDTO + streamUrl: string +} +``` + +流传输只增加应用 envelope，不发明新的消息内容协议： + +```ts +type StreamEvent = + | { type: "snapshot"; message: ThreadChatUIMessage; throughSeq: number } + | { type: "chunk"; seq: number; chunk: ThreadChatUIMessageChunk } + | { type: "terminal"; message: MessageDTO } + | { type: "heartbeat"; at: string } +``` + +### 1.3 API + +新 API 使用 `/api/thread-chat/v1` 命名空间，避免复用包含整树与计费耦合的 `/api/chat`。所有 handler 使用 Next.js 16 原生 `Request`/`Response`/`ReadableStream`，动态参数通过 `await ctx.params` 读取，默认 Node.js runtime 且禁用缓存。 + +| Method + path | 请求/响应 | 原子行为 | +|---|---|---| +| `GET /projects?archived=false` | Project 列表 | owner-scoped，按 updated_at 排序 | +| `GET /projects/:projectId` | `ProjectBootstrapDTO` | 返回完整规范化投影；合法但未创建的新 URL 返回 `project:null` 空壳 | +| `POST /projects/:projectId/start` | IDs、首条 text/files、modelId | 原子创建 Project、根 Thread、user Message、assistant Message、命令收据；提交后启动 Session | +| `PATCH /projects/:projectId` | rename/archive command | 只更新 custom title 或 archive；返回 ProjectDTO | +| `DELETE /projects/:projectId` | delete command | owner lock 后级联删除；重复删除返回同一回执 | +| `PATCH /threads/:threadId` | model/title command | 更新下一轮模型或自定义标题，不改变历史 Message modelId | +| `POST /threads/:threadId/messages` | user/assistant IDs、text/files、modelId | 分配两个连续 sequence，创建 turn，提交后启动 Session | +| `POST /threads/:threadId/forks` | sourceMessageId、anchor、newThreadId、可选首轮 IDs/text | 锁 Project 脚注计数，冻结上下文；有首轮时同事务创建并启动生成 | +| `POST /messages/:messageId/edit` | 新 user/assistant IDs、text、commandId | 仅最新活跃 user turn；soft-supersede 旧 turn，追加新 turn | +| `POST /messages/:messageId/retry` | newAssistantMessageId、commandId | 仅最新活跃 assistant；soft-supersede 目标，追加新 assistant | +| `POST /messages/:messageId/stop` | commandId | 写 `stop_requested_at` 并请求 Session abort；终态则返回现状 | +| `PUT /messages/:messageId/feedback` | commandId、`up/down/null` | 只允许 owner 对 assistant Message 设置互斥反馈 | +| `GET /messages/:messageId` | `MessageDTO` | 断流/刷新后的权威轮询端点 | +| `GET /messages/:messageId/stream` | SSE `StreamEvent` | 仅活跃或宽限期内 Session；先 snapshot，再 chunk/terminal | +| `GET /artifacts/:artifactId` | `ArtifactDTO` | owner-scoped drawer 延迟读取（bootstrap 也带摘要/现有所需内容） | + +错误码稳定为 `VALIDATION_ERROR`、`NOT_FOUND`、`COMMAND_ID_CONFLICT`、`STATE_CONFLICT`、`MODEL_NOT_ALLOWED`、`SESSION_NOT_AVAILABLE`、`GENERATION_FAILED`。owner 不匹配与资源不存在都对外表现为 404。命令成功但 Session 已不在内存时，返回的 Message ID 仍可轮询；不得因 SSE 不可用再次执行命令。 + +`GET .../stream` 使用 fetch 读取 SSE，客户端明确关闭自动重连。响应头包含 `Content-Type: text/event-stream`、`Cache-Control: no-cache, no-transform`、`X-Accel-Buffering: no`，并定时发送 heartbeat。连接取消只注销 subscriber，不把 `request.signal` 传给 `streamText`。 + +### 1.4 前端 Store + +保留“单一外部 store + React selector”架构，改为 `zustand/vanilla` 的规范化状态；不引入 Immer。Store 分成业务实体和工作区 UI 两个 slice，但由一个 facade 暴露给现有组件： + +```ts +interface ConversationEntityState { + project: ProjectDTO | null + threadsById: Record + messagesById: Record + messageIdsByThread: Record // 始终按 sequence + artifactsById: Record + artifactOrder: string[] + streamByMessageId: Record + optimisticByCommandId: Record +} + +interface WorkspaceUiState { + view: "columns" | "canvas" + openThreadIds: string[] + selectedThreadId: string + recents: string[] + canvas: CanvasUiSnapshot + panelSizes: PanelSizeSnapshot + expandedNodes: string[] +} +``` + +业务 actions：`hydrateProject`、`upsertProject/Thread/Message/Artifact`、`applyStreamSnapshot`、`applyStreamChunk`、`reconcileTerminalMessage`、`markBackgroundGeneration`、`begin/commit/rollbackOptimisticCommand`、`removeProject`。流 chunk 通过 AI SDK v7 的 UI Message reducer 归并，不再维护 `text += delta`、独立 Markdown 临时字段或 web research 旁路字段。 + +关键 selectors： + +- `selectVisibleMessages(threadId)`：只投影 `supersededAt === null` 的当前时间线；生成中优先使用 `liveMessage.parts`，终态使用 MessageDTO.parts。 +- `selectAllMessageEntities(threadId)`：供 frozen context、来源与调试使用，不直接渲染版本选择器。 +- `selectThreadTree()`、`selectChildren(threadId)`、`selectLineage(threadId)`：从 ThreadDTO 的 parent 关系派生。 +- `selectForkMarkers(messageId)`、`selectSourceProvenance(threadId)`：从 `forkMessageId/anchor/footnote` 派生，旧来源被 supersede 后仍可解析。 +- `selectArtifactsForMessage/Project`：从规范化 Artifact 关系派生。 +- `selectDisplayTitle`：`customTitle ?? autoTitle ?? existing fallback`。 + +工作区 slice 继续按 Project ID 写 localStorage，仅保存布局/打开列/画布/面板状态。它绝不保存业务 Message 或覆盖 bootstrap。命令层使用客户端 UUID 乐观插入临时实体，响应成功后以 DTO 校正；失败只回滚对应 command patch。 + +### 1.5 模块拆分与依赖方向 + +```text +lib/thread-chat/ + domain/ + types.ts # 领域 ID、状态、TextAnchor、Artifact 等纯类型 + state-machine.ts # generating -> terminal 与

+## 2. Context + +动机见 [proposal.md](./proposal.md)。当前 `branch_trees.state` 同时保存拓扑、消息、Artifact 和工作区派生状态，`branch_generations` 又保存一次生成的快照、结果、心跳与 billing 状态；浏览器还维护 active leaf/variant 与流临时字段。三个层面都能改变“当前回复”，是竞态根源。 + +项目实际为 Next.js 16.3.1、React 19、Drizzle/Postgres、`ai@^7.0.14`、`@ai-sdk/react@^4` 与 `zustand@^5`。Next.js 16 Route Handler 使用 Web API；AI SDK v7 中模型 `TextStreamPart`、传输 `UIMessageChunk` 和最终 `UIMessage.parts[]` 是三层不同类型。设计必须以安装版本类型声明为准，不使用已废弃的 `StreamTextResult.toUIMessageStream()` 路径。 + +部署目标是用户完全控制的 VPS，并明确固定一个 Next.js 进程/副本。因此进程内 Session 可接受；多实例容错、跨进程续传不是本次目标。HTTP/SSE 连接仍然是不可靠的，不能拥有模型任务。 + +## 3.

AND status='generating'`；任何 Retry/Stop/finalize 重入都返回已存在的权威行。Retry 在事务中先校验目标仍为最新活跃 assistant，再创建 B 并 soft-supersede A；B 失败后的新命令创建 C。相同 command ID 只回放 B/C 的创建收据。 + +替代方案是保留 Message + Generation 两层和 active leaf。它能提供版本切换，但这正是已决定移除的 UX，并会延续两套身份与 merge 逻辑，所以拒绝。 + +### D2：分支保存 Message ID 冻结上下文 + +创建分支时，在锁定 Project/父 Thread 的事务中计算： + +```text +child.fork_context = + parent.fork_context + + parent 当前时间线中从开头到 sourceMessage（含）的 Message IDs +``` + +该数组只在创建时写一次。子 Thread 自己的后续上下文为 `fork_context` 对应的历史 Message，加上子 Thread 当前时间线。上下文编译从数据库按 ID 读取 `parts[]`，忽略这些历史行是否已 supersede；缺失/跨项目 ID 是数据完整性错误，不静默换成新回复。 + +替代方案是在每次调用时沿父线程“当前回复”重算，会让 X 随 A→B 漂移，与已确认的“X 和 B 无关”冲突。 + +### D3：数据库事务先提交，Session 后启动 + +创建生成命令的事务顺序为：owner lock → idempotency receipt 检查 → 状态校验 → 原子 sequence 分配 → 写 Message/关系/收据 → commit。提交成功后，同一请求进程立即调用 `SessionStore.start()`；它先把 Session 放入 Map，再启动且持有 task Promise。启动同步失败或任务异常都走唯一 finalize service 收敛为 failed。 + +不能在数据库事务内等待模型，也不能先调用模型再写 Message。前者长时间占锁，后者在写入失败时产生无法归属的付费执行。commit 与 Session 注册间的进程崩溃是单进程无 durable queue 的已知窗口；下一次进程初始化会把该 `generating` 行标为 failed，用户可 Retry。 + +### D4：使用 AI SDK v7 的 UI Message pipeline，而非 textStream + +生成引擎调用 `streamText`，只把 Session 自己的 `AbortController.signal` 作为 abortSignal。使用独立函数： + +```text +streamText(...).stream -> TextStreamPart +toUIMessageStream({ stream, ... }) -> UIMessageChunk +readUIMessageStream({ stream, ... }) -> evolving UIMessage snapshots +``` + +`toUIMessageStream` 固定 `responseMessageId=assistantMessage.id`，开启 reasoning/sources，并通过 `onEnd({ responseMessage, isAborted, finishReason })` 提供协议级终结事实。Session 顺序处理每个 chunk：先经 AI SDK reducer 更新完整 snapshot，再编号并广播，保证新订阅获得的 snapshot 覆盖所有已广播 chunk。`runGeneration` 在流消费退出后仅调用一次 finalize；异常、abort 和正常结束都映射到同一个收口函数。 + +替代方案 `result.textStream` 会丢失工具、来源、推理和 data parts；手写多个字段又会重建当前问题。实例方法 `result.toUIMessageStream()` 在安装版本已标记废弃，不采用。 + +### D5：Session 使用 globalThis 单例 Map，但明确单进程约束 + +`SessionStore` 以 `globalThis` Symbol 保存，避免开发 HMR 重复实例；Session 包含 messageId、status、snapshot、eventSeq、AbortController、subscriber Set、finishedAt、task Promise。task Promise 在 Store 内立即附加 catch，任何 handler 不拥有它，也不需要 Next.js `after()` 保活。 + +订阅方法在同一同步临界段完成“加入 subscriber → 发送 snapshot/throughSeq → 发送之后的事件”；JS 单线程与 snapshot-before-broadcast 规则避免 subscribe race。终态 Session 保留 5 分钟（常量可调）后清理；cleanup 比较 `now - finishedAt >= ttl`，只删终态、无订阅者的 Session，timer 调用 `unref()`。 + +这个选择不适用于 PM2 cluster、多容器或滚动双副本。部署 Gate 必须检查只有一个副本和一个 Node 进程。 + +### D6：断流不重连，轮询数据库终态 + +首次命令接受后客户端建立一次 fetch-SSE。断开时 abort 本地 reader、保留 live snapshot、标记 background，并以退避间隔轮询 `GET /messages/:id`（建议 1s、2s、2s，之后 3s，上限 5s）。不发送 Last-Event-ID，不自动 reconnect，不要求服务器 replay。 + +Session 在生成中每 750–1000ms 对变更后的非 transient `parts[]` 做节流 checkpoint，条件仍为 `status='generating'`；finalize 强制 flush 最终 parts。这样刷新可看到最近快照，最终一定由 terminal row 覆盖。断流页面保留的内存快照若比 DB checkpoint 更新，不被较旧的 generating poll 覆盖；只有序号/更新时间更新或终态才能前进。 + +### D7：后台消费方唯一终结，Stop 只 abort + +Stop 命令先 owner/state 校验，幂等写 `stop_requested_at`，再查找 Session 并调用 abort。它不直接把 Message 改成 stopped。`runGeneration` 从 AI SDK `isAborted` 判断 stopped，而不是捕获字符串形态的 AbortError；模型恰好先完成时 CAS 使 completed 获胜。若 Session 已丢失而行仍 generating，Stop 可通过同一“无 Session 遗留收敛”服务将其标为 failed，而不是伪造 stopped。 + +### D8：Artifact 是独立记录，UI 协议仍保留工具 parts + +工具输入/输出按 UI Message tool part 原样保存在 Message；可打开的 Markdown 等长期产物同时写 `artifacts`，tool output 持有 artifactId。生成期间只在 Session snapshot 展示临时进度；finalize 从验证后的最终 tool outputs 收集 Artifact，并与 Message 终态同事务 upsert。不存在“先写 Artifact、Message 失败后孤立”的路径。 + +### D9：标题保持双轨和一次触发，不复用计费链路 + +Project 与 Thread 都保存 auto/custom 字段。主 Thread 的自定义标题同时作为 Project 导航标题；selector 按现有优先级展示。首次有效 turn 提交后由独立 title service 异步尝试一次，`title_generation_attempted` 无论成功失败均置 true；标题模型调用不得经过余额或扣费逻辑。 + +### D10：旧计费代码保留但物理隔离 + +为避免超出本次 UX 范围，billing 页面与表可暂时留在仓库；新 `/api/thread-chat/v1`、application、streaming 和 title service 通过依赖扫描测试禁止 import 计费模块。`provider_usage` 只保存提供商原始字段，字段名和代码不得出现 cost、credits、billingStatus、charged 等解释。旧 `/api/chat` 不作为新 ThreadChat 调用入口。 + +### D11：测试沿用项目现有 Node 脚本，并增加协议/并发分层 + +仓库已有大量 `node --import tsx` 与数据库脚本，且没有直接测试框架依赖；本 change 不为架构改造额外引入 Vitest。纯领域、contracts、Store 和 stream reducer 用现有 Node assert 脚本；仓储/命令/竞态用随机测试用户和事务清理的 Postgres 脚本；真实 UI 必须按仓库规则用 `ego-browser nodejs` 对 localhost 做验收。旧版本切换、billing 和整树持久化测试在 cutover Gate 删除或改写，不能作为新契约通过的假信号。 + +## 5. 并发与状态流程 + +### 5.1 Send + +```text +client optimistic IDs + -> POST command + -> DB transaction + command receipt + generating assistant + -> JSON accepted + -> SessionStore.start(messageId) + -> one-shot SSE snapshot/chunks + -> checkpoint while generating + -> finalize CAS + Artifact transaction + -> terminal event / polling convergence +``` + +如果重复 POST 到达：命令表返回同一 assistant ID；若 Session 尚活跃则可订阅，否则轮询数据库，绝不二次 `streamText`。 + +### 5.2 Retry/Regenerate + +锁定目标 Thread 与 Message，要求目标是最新可见 assistant 且已终态；同事务分配一个新 sequence、创建 B(`replaces=A`)、设置 A.superseded_at、写收据。A 的 status/parts/Artifact 不变。任何以 A 为来源的分支不更新。非幂等的第二个新 command 在 A 已 supersede 后返回 409。 + +### 5.3 Edit latest user + +只支持现有 UX 中的最新 user turn。事务 soft-supersede 原 user 和当前 assistant（如有），追加新 user 与新 assistant 两行。旧 assistant 若仍 generating，提交后请求其 Session abort；旧 Session 的 finalize CAS 仍可把旧行终结，但旧行保持 superseded，不影响新时间线。 + +### 5.4 Process initialization + +新进程在接受 ThreadChat 命令前初始化 singleton，并把数据库中所有 `generating` Message 视为上一个进程遗留，条件更新为 failed（错误码 `PROCESS_RESTARTED`）。由于部署保证只有一个进程，不需要 lease/heartbeat 判断另一个实例是否仍活跃。初始化必须是一次性 Promise，所有路由 await 它，避免并发首请求重复 sweep。 + +## 6.

It provides a unified API across model providers for text generation, structured output, tool calling, agents, embeddings, and framework UI integrations. + +- Repository: https://github.com/vercel/ai +- Documentation: https://ai-sdk.dev/docs + +## Critical: Do Not Trust Your Own Memory + +Whatever you remember about the AI SDK is likely outdated. The SDK changes frequently across versions - APIs are renamed, removed, and added. Your training data almost certainly contains obsolete APIs, deprecated patterns, and model IDs that no longer exist. UI hooks like `useChat` are among the most frequently changed APIs, so be especially careful with client code. + +**Never write AI SDK code from memory.** Always verify every API, option, and pattern against the documentation and source code for the version that is actually installed in the project. + +## Use the Bundled, Version-Matched Docs + +The `ai` package ships its full documentation and source code inside `node_modules`. These always match the installed version, so trust them over anything you remember. + +1. Ensure `ai` is installed. If `node_modules/ai/` does not exist, install **only** the `ai` package using the project's package manager (e.g. `pnpm add ai`). Install provider packages (e.g. `@ai-sdk/openai`) and framework packages (e.g. `@ai-sdk/react`) later, when the task requires them. +2. Read and grep the bundled docs at `node_modules/ai/docs/` and the source at `node_modules/ai/src/`. +3. Provider and framework packages bundle their own docs at `node_modules/@ai-sdk//docs/`. +4. If something isn't in the bundled docs, search https://ai-sdk.dev/docs. You can append `.md` to any docs page URL to get its markdown, and search via `https://ai-sdk.dev/api/search-docs?q=your_query`. +5. If you cannot find support for an answer in the docs or source, say so explicitly — do not guess. + +## AI Gateway: The Fastest Way to Start + +The Vercel AI Gateway is the fastest way to get started with the AI SDK. It provides access to models from OpenAI, Anthropic, Google, and other providers through a single API, without installing provider packages or managing multiple API keys. + +To set it up: + +1. Authenticate with OIDC (for Vercel deployments) or get an AI Gateway API key. +2. Provide it to your app via the `AI_GATEWAY_API_KEY` environment variable. +3. Reference models with `provider/model` strings. + +For exact setup, authentication, and usage, read the bundled guide and the AI Gateway docs. + +### Choosing a Model + +Never use model IDs from memory — models are released and retired frequently. Fetch the current list before writing code that references a model. Do not truncate the list (e.g. with `head`) so you can find the newest models: + +```bash +# All available models +curl -s https://ai-gateway.vercel.sh/v1/models | jq -r '.data[].id' + +# Filter by provider (e.g. anthropic, openai, google) +curl -s https://ai-gateway.vercel.sh/v1/models | jq -r '[.data[] | select(.id | startswith("anthropic/")) | .id] | reverse | .[]' +``` + +When multiple versions of a model exist, prefer the one with the highest version number. + +## Building and Consuming Agents + +Use the SDK's built-in agent abstraction (such as `ToolLoopAgent`) rather than hand-rolling tool-calling loops. For end-to-end type safety, infer the UI message type from your agent definition when consuming it on the client (e.g. with `useChat`). Consuming an agent is framework-specific: check `package.json` to detect the stack, then follow the matching quickstart. + +Look up the current agent, tool, and type-safety APIs in the bundled docs (`node_modules/ai/docs/`, especially the agents section) or at https://ai-sdk.dev/docs. + +## DevTools + +AI SDK DevTools captures your AI SDK calls - requests, responses, tool calls, token usage, and multi-step runs - so you can inspect exactly what your agents do.

Fork 使用 `forkContext` 冻结来源消息，并校验来源是否仍在当前时间线。 +- 写命令具有 `commandId`，`executeIdempotentCommand` 能避免同一请求重复执行。 +- Attachment 已有上传状态、类型、大小和 PDF 内容处理。 +- Artifact 已能由模型工具创建，并关联 `projectId` 与 `sourceMessageId`。 +- `compileModelContext` 已是统一的模型上下文编译入口。 +- 当前 Agent Evaluation 已包含同 Thread 事实、更正、长上下文、冻结分支和跨 Project 不泄漏等场景。 + +这意味着 Project 应沿着现有的 Domain Command、规范化状态和统一上下文编译边界扩展，而不是另建一套平行聊天系统。 + +### 2.2 主要差距 + +| 目标能力 | 当前状态 | 主要差距 | 风险 | +|---|---|---|---| +| Project Contract | Project 主要只有标题、归档和时间字段 | 没有 Target、Instructions、Pinned Memory 及版本语义 | 高 | +| Project File | Attachment 更接近消息附件 | 缺少逻辑 File、版本、替换、归档、派生和引用语义 | 高 | +| Artifact | 单条记录直接保存内容 | 缺少稳定身份、Revision、Head、Fork、Revert、并发冲突 | 高 | +| Operation | 有幂等 Command Receipt | Receipt 不是面向用户和 Agent 的领域活动记录 | 高 | +| 跨 Thread 引用 | 有 Fork 和 Quote | 没有一等 `@Thread/@File/@Artifact` Reference | 高 | +| 支线汇总 | 可以创建多个 Fork | 没有阶段快照、可汇总状态、来源包和冲突模型 | 高 | +| Memory | 评测中已有“记住事实”的概念 | 尚无 Project Memory 领域对象、确认流程和作用域 | 中高 | +| Agent 上下文 | 主要由冻结消息、当前 Thread、Attachment、Quote 组成 | 尚未选择性装配 Contract、Reference、Memory、Activity | 高 | +| Evaluation | 以回答文本和运行终态为主 | 缺少资源状态、版本和副作用断言 | 中高 | + +--- + +## 三、外部产品基准 + +### 3.1 Claude Projects + +Claude Projects 的长处是： + +- Project Instructions 与 Project Knowledge 作为项目级上下文； +- 项目文件可以在多个聊天中复用； +- Artifacts 能把独立产物从聊天正文中分离出来； +- 项目内容超过上下文窗口后使用 RAG 检索。 + +它暴露出的设计问题也很明确： + +- Project Knowledge、聊天历史、Artifact 和 Memory 的边界对普通用户不够直观； +- Artifact 更接近聊天内产物，版本和跨聊天协作语义不够强； +- 多条聊天如何形成正式、可追踪的阶段成果，缺少显式工作流； +- 项目级共享知识容易被用户理解成“模型自动知道项目里的一切”。 + +ThreadChat 不应简单复制“共享文件 + Instructions”，而应利用自身分支结构，把引用和汇总做成一等能力。 + +### 3.2 ChatGPT Projects + +ChatGPT Projects 的优势是把 Project Memory 与项目内聊天历史联系得更紧，用户在同一 Project 中开启新聊天时，系统能够引用项目内的其他对话和文件。 + +这种体验自然，但存在一个工程风险：如果“引用过去聊天”没有显式来源、版本和范围，用户很难知道某个回答究竟受哪些旧对话影响。ThreadChat 应保留这种连续感，同时增加可见来源和显式固定版本。 + +### 3.3 Perplexity Spaces、NotebookLM、Notion + +这些产品提供了三个值得借鉴的方向： + +- Perplexity Spaces：把共享搜索、文件和协作组织到一个主题空间中。 +- NotebookLM：强调回答基于指定来源；外部来源变化时需要显式重新同步，而不是静默变化。 +- Notion Enterprise Search：强调可选择的来源范围、引用和权限边界。 + +共同启示是：**来源范围必须可见，更新传播必须可控。** + +### 3.4 差异化机会 + +ThreadChat 最有价值的差异不是“也支持 Project 文件”，而是： + +```text +一条主线 +→ 基于具体段落分叉多条支线 +→ 每条支线形成可发布的阶段结论 +→ 支线之间显式引用 +→ 主线按明确版本汇总 +→ 用户可追踪每项结论来自哪里 +``` + +这是普通线性聊天 Project 最难自然表达的工作模式。 + +--- + +## 四、推荐的总体机制 + +### 4.1 五类不同对象 + +| 对象 | 回答的问题 | 示例 | +|---|---|---| +| Current State | 现在是什么 | Artifact 当前 Head 是 Revision 4 | +| Revision / Version | 当时是什么 | Revision 2 的内容和来源 | +| Operation | 发生了什么 | 用户将 Head 从 Revision 3 更新到 Revision 4 | +| Memory | 未来应继续影响 Agent 的什么 | 项目决定所有公开 API 使用 REST | +| Contract | Agent 必须遵守什么 | 不允许静默覆盖原始资料 | + +如果把这些概念混在一起，会出现两类错误： + +- 把所有历史操作都塞给模型，导致噪声、旧状态竞争和成本持续增长； +- 只保存最终状态，导致来源、修改原因和并发冲突无法解释。 + +### 4.2 推荐组合 + +```text +权威状态表 + 保存逻辑对象及其当前 Head + +不可变版本表 + 保存 Contract、File、Artifact、Thread Snapshot 的历史内容 + +显式 Reference + 保存引用对象、固定版本、创建来源和刷新关系 + +Project Operation Ledger + 保存有业务意义的操作，不作为状态唯一来源 + +Activity Summary + 从 Operation 中筛选与当前任务相关的近期变化 + +Memory + 保存经确认、未来应继续影响 Agent 的语义事实 +``` + +### 4.3 为什么不采用完整 Event Sourcing + +完整 Event Sourcing 要求当前状态主要由历史事件重放得到，并引入事件版本迁移、顺序、快照、重建、最终一致性和历史兼容等长期成本。 + +ThreadChat 当前真正需要的是： + +- 不可变历史； +- 资源来源追踪； +- 并发修改检测； +- 用户可见活动； +- Agent 能读取近期相关变化； +- 必要时恢复旧版本。 + +这些目标使用“正常状态 + 不可变版本 + 只追加操作记录”即可满足。完整 Event Sourcing 会扩大实现面，但不会显著改善首版用户价值。 + +--- + +## 五、Project Contract + +### 5.1 职责边界 + +Contract 在产品上由三部分组成： + +| 部分 | 作用 | 典型内容 | +|---|---|---| +| Target | 定义当前 Project 要达成什么 | “完成一份可提交投资委员会的研究 Memo” | +| Instructions | 定义工作方式和约束 | “所有结论必须保留来源；不要修改原始文件” | +| Pinned Memory | 保存用户确认的重要事实或决策 | “估值口径统一使用投后估值” | + +Pinned Memory 可以在 UI 上和 Contract 放在同一区域，但底层不应等同于 Instructions： + +- Instructions 具有规范性，告诉 Agent 应该怎么做； +- Memory 具有事实性，告诉 Agent 已经确认了什么。 + +### 5.2 版本策略 + +推荐 Contract 整体拥有版本历史，并允许查看每次修改的差异和操作人。原因是 Target、Instructions、Pinned Memory 共同定义 Project 的工作环境；后续需要回答“某个 Thread 当时遵循哪个 Contract”。 + +但三个区域在 Spec 阶段仍可采用独立编辑入口，避免用户为了新增一条 Memory 而重写整个 Contract。 + +### 5.3 对既有 Thread 的影响 + +Contract 更新后： + +- 新一轮模型调用读取当前 Contract； +- 已经生成的消息和已发布的 Thread Snapshot 不被改写； +- 高风险情况下，可记录某次生成使用的 Contract Version，便于复现； +- 如果更新使某个旧结论失效，系统提示“该结论基于旧 Contract”，而不是静默重算。 + +--- + +## 六、Project Files + +### 6.1 File 不是单次上传记录 + +推荐区分： + +```text +File + 用户理解的稳定资源，例如“2026 年预算.xlsx” + +File Version + 某次上传的不可变二进制及其解析结果 +``` + +Attachment 可以继续承担上传和消息引用，但成为 Project 长期资产后，应归属一个稳定 File 身份。 + +### 6.2 更新、替换与另存为 + +建议产品语义： + +- **上传新版本**：在同一 File 下增加 File Version，并更新当前版本。 +- **另存为新文件**：创建新的 File 身份。 +- **移出 Project**：不再作为项目资产参与检索，但可保留历史引用。 +- **归档**：不在常用列表展示，历史引用仍有效。 +- **永久删除**：高风险操作；如果存在历史引用，需明确告知影响或先执行保留策略。 + +### 6.3 Agent 对原始文件的操作 + +默认规则： + +```text +Agent 不原地修改用户上传的 File Version。 +``` + +当用户说“把这份 PDF 改写成更简洁的版本”时，合理结果是创建一个 Derived Artifact，而不是改写 PDF 原件。 + +只有用户明确要求“将新版本作为这个逻辑 File 的当前版本”，并且系统支持对应格式的安全写入时，才增加新的 File Version。 + +### 6.4 引用策略 + +历史 Thread 对 File 的引用绑定明确 File Version。File 有新版本后： + +- 旧 Thread 仍使用原版本； +- UI 标记“该 File 已有新版本”； +- 用户可显式刷新引用； +- 刷新操作产生新的 Reference 或 Reference Revision，不重写历史消息。 + +--- + +## 七、Artifact 生命周期 + +### 7.1 推荐模型 + +```text +Artifact + 稳定逻辑身份：标题、类型、当前 Head、归档状态 + +Artifact Revision + 不可变内容：正文、语言、来源、父 Revision、创建者、时间 +``` + +Markdown、HTML、CSS、JS、TS 和普通 Note 可以共享同一生命周期；格式差异主要体现在内容类型、渲染器和验证器，而不是每种格式各自建立版本系统。 + +### 7.2 Create、Revise、Fork、Revert + +| 动作 | 语义 | +|---|---| +| Create | 创建 Artifact 和首个 Revision | +| Revise | 基于当前或指定 Revision 生成新 Revision，并尝试更新 Head | +| Fork | 从指定 Revision 创建新的 Artifact 身份 | +| Revert | 创建一个内容等同于旧 Revision 的新 Revision，并将其设为 Head | +| Archive | 隐藏 Artifact，但保留历史和引用 | + +Revert 不应直接把 Head 指针悄悄拨回旧版本；创建新的恢复 Revision 更容易保留操作历史。 + +### 7.3 并发修改 + +两个 Thread 同时修改同一 Artifact 时，不能采用“最后一次写入获胜”。推荐使用 Expected Head： + +```text +B1 读取 Revision 3 +B2 读取 Revision 3 +B1 提交 Revision 4，Head = 4 +B2 提交时仍声明 expectedHead = 3 +系统发现当前 Head 已是 4 +→ 拒绝静默覆盖 +→ 提供重新基于 4 修改、Fork 或人工合并 +``` + +这类条件写入与 Git 的 compare-and-swap 思路一致，能够把冲突暴露在提交边界。 + +### 7.4 来源追踪 + +每个 Artifact Revision 至少应能追溯： + +- 创建它的 Project； +- 来源 Thread； +- 来源 Message 或 Agent Run； +- 父 Artifact Revision； +- 使用的 File Version、Artifact Revision、Thread Snapshot； +- 创建者是用户还是 Agent； +- 所依据的 Contract Version。 + +具体字段属于 Spec 阶段，但 Research 阶段确认：**来源追踪是 Revision 的属性，而不只是 Artifact 的属性。** + +--- + +## 八、Project Operation 与 Activity + +### 8.1 为什么 Command Receipt 不够 + +现有 `conversation_commands` 适合解决写请求幂等：相同 `commandId` 和相同内容可以重放，相同 `commandId` 被用于不同命令时拒绝。 + +但它不等同于 Project Operation： + +- Receipt 面向请求执行； +- Operation 面向领域事实和用户理解； +- Receipt 可以因内部实现变化而变化； +- Operation 应使用稳定的业务语义。 + +两者应保持分离，但可以在同一事务中写入，使业务状态、Receipt 和 Operation 原子提交。 + +### 8.2 应记录的操作 + +首版建议记录： + +```text +contract.revised +file.created +file.version_added +file.archived +artifact.created +artifact.revised +artifact.forked +artifact.reverted +artifact.archived +reference.created +reference.refreshed +thread.snapshot_published +convergence.created +memory.candidate_created +memory.promoted +memory.superseded +write.conflict_detected +``` + +### 8.3 不应进入领域操作记录的行为 + +- 打开 Tab； +- 鼠标悬停； +- 滚动位置； +- 尚未提交的输入框内容； +- 本地展开或折叠； +- 只发生文本选择但没有创建 Fork/Reference。 + +这些最多属于产品 Telemetry。只有产生业务状态变化的行为才进入 Project Operation。 + +### 8.4 EventSource 的正确位置 + +推荐链路： + +```text +用户或 Agent 执行命令 +→ 服务端事务提交权威状态、Revision、Operation +→ 服务端通过 SSE 发布轻量通知 +→ 浏览器 EventSource 接收并更新界面 +``` + +EventSource 解决的是“浏览器如何及时知道服务器有变化”。它不负责长期保存、不保证 Agent 已知晓，也不能作为唯一事实来源。 + +### 8.5 Agent 如何知道最近操作 + +LLM 不应自动接收整个 Operation Ledger。推荐提供两个受控入口： + +1. 上下文编译器按任务需要加入一小段“近期相关变化摘要”； +2. Agent 在需要检查更新、冲突或来源时调用 Activity 工具。 + +示例： + +```text +- Thread B3 发布了新的阶段总结 Snapshot 5。 +- Artifact“数据模型”已从 Revision 2 更新至 Revision 3。 +- 当前 Thread 仍引用 Revision 2。 +``` + +这个摘要是从 Operation 和当前状态计算出的任务视图，不是 Memory。 + +--- + +## 九、Operation 与 Memory 的边界 + +### 9.1 三者关系 + +```text +Operation：发生了什么 +Memory：未来应该记住什么 +Contract：未来必须遵守什么 +``` + +例如： + +```text +Operation +用户将“架构方案”更新为 Revision 4。 + +可能的 Memory Candidate +项目已经决定 Artifact 采用不可变 Revision。 + +Pinned Memory +用户确认：后续所有正式 Artifact 必须保留历史版本。 + +Instruction +Agent 修改正式 Artifact 前必须显示差异，并禁止静默覆盖。 +``` + +### 9.2 推荐的记忆流程 + +```text +对话、Artifact 或 Operation 中出现潜在长期事实 +→ Agent 或规则创建 Memory Candidate +→ 用户确认，或命中已明确授权的策略 +→ Active / Pinned Memory +→ 后续被新事实替代时标记 Superseded +``` + +### 9.3 本轮建议的记忆层级 + +| 层级 | 作用域 | 说明 | +|---|---|---| +| Personal Memory | 用户级 | 跨 Project 的稳定偏好；本轮不细化 | +| Project Pinned Memory | Project | 用户明确确认的重要事实、口径、决策 | +| Project Working Memory | Project | 可更新的工作状态，不保证永久有效 | +| Project Decisions / Knowledge | Project | 已形成来源的正式结论，可由 Artifact 或 Snapshot 支撑 | +| Thread Memory | Thread | 只影响本支线的阶段事实和局部假设 | +| Current Working Context | 单次生成 | 当前消息、显式引用、临时选择，不持久化为 Memory | + +Operation/Activity 不作为 Memory 层级；它们可以成为产生 Memory Candidate 的证据。 + +--- + +## 十、跨 Thread 引用与汇总 + +### 10.1 Reference 必须是一等对象 + +仅把 `@B1` 展开成一段文本会丢失来源和版本。Reference 至少要表达： + +```text +引用者：当前 Thread / Message / Artifact Revision +被引用对象：Thread / File / Artifact / Memory +固定版本：Thread Snapshot / File Version / Artifact Revision +创建时间与创建者 +引用目的或选区 +是否已有更新 +刷新后指向哪个新版本 +``` + +### 10.2 `@Thread` 的默认含义 + +不建议默认把整个 Thread 原始历史全部塞入上下文。推荐解析顺序： + +1. 若用户指定某条消息或选区，引用该明确内容； +2. 若 Thread 已发布阶段 Snapshot，默认引用最新已发布 Snapshot； +3. 若没有 Snapshot，提示用户先生成/发布总结，或临时生成一个明确标记的摘要； +4. 只有用户明确要求审查全过程时，才读取更大范围的原始历史。 + +Thread Snapshot 是可引用的阶段成果，不等同于 Memory；它保留本支线当时的结论、证据、假设、冲突和未解决问题。 + +### 10.3 支线变化如何传播 + +```text +B1 发布 Snapshot 2 +A 引用 Snapshot 2 +B1 后续发布 Snapshot 3 +A 仍保留 Snapshot 2 +系统显示“B1 已有新 Snapshot” +用户选择刷新后，A 创建对 Snapshot 3 的新引用 +``` + +不自动刷新，是为了保证历史可重现并避免支线悄悄改变其他 Thread 的回答。 + +### 10.4 五条支线汇总的默认流程 + +假设主线 A 分出 B1—B5： + +```text +B1—B5 分别研究 +→ 每条支线发布一个阶段 Snapshot +→ A 创建 Convergence Bundle +→ Bundle 固定五个 Snapshot ID +→ Agent 读取五份结构化阶段结论 +→ 标识共识、冲突、证据缺口和过期来源 +→ 生成主线总结或新的 Artifact Revision +→ 结果保留对五个来源 Snapshot 的追踪 +``` + +Convergence Bundle 的价值是让“这次汇总究竟用了哪些版本”成为显式事实。用户也可以直接 `@B1 @B2 ...`，系统在后台把它们解析成同一组固定 Snapshot。 + +### 10.5 `@Thread` 与总结 Artifact 的关系 + +两条路径都应支持： + +- `@Thread`：适合探索中、尚未形成正式文档的支线；默认读取已发布 Snapshot。 +- `@Artifact`：适合已经形成正式成果的支线；引用明确 Artifact Revision。 + +普通用户默认使用 `@Thread` 更自然；正式交付、审计和反复修改时，Artifact Revision 更稳定。二者最终都通过统一 Reference 机制进入上下文。 + +--- + +## 十一、Agent 资源访问与可预测行为 + +### 11.1 读取策略 + +Agent 默认可以读取： + +- 当前 Project Contract； +- 当前 Thread 及冻结继承上下文； +- 用户本轮显式 `@` 的资源； +- 与本轮任务直接相关的 Pinned Memory； +- 为检查冲突所需的资源当前 Head 和相关 Activity。 + +Agent 不应无差别读取整个 Project 的所有文件、聊天、Artifact 和操作历史。 + +### 11.2 操作权限矩阵 + +| 操作 | 默认策略 | +|---|---| +| 读取显式引用资源 | 直接允许 | +| 创建新的 Artifact | 明确请求时允许，完成后清楚反馈 | +| 基于 Artifact 创建新 Revision | 显示目标 Artifact、父 Revision 和差异；校验 Expected Head | +| Fork Artifact | 允许，但必须说明会创建新对象而不是修改原件 | +| 增加 File Version | 需要明确目标 File；高价值资料建议确认

11.3 模糊指令的处理 + +用户说“改一下这个文档”时，Agent 必须先解析明确目标： + +- 当前打开的 Artifact 是哪个； +- 当前显示的是哪个 Revision； +- 用户想更新原 Artifact、Fork 新 Artifact，还是生成派生版本； +- Head 是否已在其他 Thread 中更新。 + +如果界面状态能够唯一确定目标，可直接执行并在操作结果中回显；如果不能唯一确定，才需要用户选择。 + +### 11.4 操作结果反馈 + +每个持久化写操作都应明确告诉用户： + +```text +已创建 / 已修改什么 +旧版本与新版本 +是否改变当前 Head +是否影响其他 Thread +是否产生过期引用 +是否存在冲突或需要后续处理 +``` + +这比只显示“完成”更能建立可预测性。 + +--- + +## 十二、模型上下文装配 + +推荐在现有 `compileModelContext` 之上逐层加入： + +```text +1. 稳定的 Agent System Prompt +2. 当前 Project Contract +3. 与任务相关的 Pinned Memory +4. 当前 Thread 的冻结继承上下文 +5. 当前 Thread 消息 +6. 用户本轮显式 Reference 的固定内容 +7. 必要的近期相关变化摘要 +8. 当前用户消息 +``` + +关键原则： + +- 权威状态优先于原始 Operation； +- 显式引用优先于全 Project 搜索； +- 固定版本优先于“总是取最新”； +- Activity 只在与任务相关时进入； +- Memory 必须携带作用域和状态； +- 旧版本可以被引用，但必须标记其版本与过期状态； +- 跨 Project 内容必须在所有读取路径上做所有权校验。 + +--- + +## 十三、核心风险验证 + +### 实验 1：是否需要完整 Event Sourcing + +**问题：** 不把事件作为唯一状态来源，能否实现审计、恢复、并发和 Agent 活动感知？ + +**方法：** 用 Artifact 修改流程对比三种方案：只保存当前内容、完整 Event Sourcing、当前状态 + Revision + Operation。 + +**结论：** 第三种方案已覆盖首版关键需求；完整 Event Sourcing 增加事件重放和版本迁移成本，却不产生同等用户价值。 + +**影响：** Spec 阶段不设计全系统事件重放；Operation 是附加的领域事实记录。 + +### 实验 2：Operation 能否替代 Memory + +**问题：** 是否可以把用户操作直接作为 LLM 长期记忆？ + +**方法：** 构造“重命名、打开、归档、更新文档、确认技术决策”等操作，判断哪些应影响未来回答。 + +**结论：** 大多数操作没有长期语义；直接作为 Memory 会引入大量噪声。只有从操作或内容中提炼出的稳定事实，才应进入 Candidate—确认流程。 + +### 实验 3：自动跟随最新版本是否更友好 + +**问题：** Reference 是否应总是解析到资源最新 Head？ + +**方法：** B1 引用 Artifact Revision 2 后，B2 将 Head 更新到 Revision 3，再复现 B1 历史回答。 + +**结论：** 自动跟随会改变历史语义，并导致无法复现。固定版本 + 更新提示 + 显式刷新更可靠。 + +### 实验 4：最后写入获胜是否足够 + +**问题：** 两条 Thread 同时修改 Artifact，能否让后提交者直接覆盖？ + +**方法：** 两者都基于 Revision 3 修改；B1 先提交 Revision 4，B2 随后提交。 + +**结论：** 最后写入获胜会静默丢失 B1 工作。Expected Head 校验能够在提交边界发现冲突。 + +### 实验 5：汇总是否可以只读取五条 Thread 的最后一条消息 + +**问题：** A 汇总 B1—B5 时，读取每条支线最后一条消息是否足够？ + +**结论：** 不足。最后一条消息可能只是追问、失败响应或局部修改。需要可发布 Snapshot，明确保存结论、证据、假设、冲突和未解决问题。 + +--- + +## 十四、Project 行为评测 + +### 14.1 评测模型需要扩展 + +当前评测主要输入消息和附件，并断言回答内容、路由、工具与终态。Project 评测还需要： + +- 初始 Project 状态； +- Contract Version； +- Files 与 File Versions； +- Artifacts 与 Revisions/Head； +- References； +- Thread Snapshots； +- 预期 Operation； +- 预期最终状态和禁止副作用。 + +具体测试 Schema 属于 Spec 阶段。 + +### 14.2 P0 场景 + +1. **原始 File 不可覆盖**：要求 Agent 修改上传文件，结果必须创建派生 Artifact 或新 File Version。 +2. **Artifact 更新产生新 Revision**：旧 Revision 保留，Head 正确更新。 +3. **并发冲突**：Expected Head 过期时拒绝静默写入。 +4. **固定 Reference**：来源更新后，历史 Thread 仍读取旧版本并显示更新提示。 +5. **跨 Thread 不隐式污染**：B1 的新结论不自动进入 B2。 +6. **五支线汇总**：结果包含全部五个 Snapshot 来源，并指出冲突和缺失。 +7. **Operation 不自动成为 Memory**：普通重命名或归档不影响未来回答。 +8. **Memory 晋升需要确认**：Candidate 未确认前不作为 Pinned Memory 使用。 +9. **跨 Project 无泄漏**：任何 File、Artifact、Reference、Activity、Memory 读取都受 Project 所有权限制。 +10. **模糊修改目标**：存在多个同名 Artifact 时不得静默选择错误对象。 + +### 14.3 关键指标 + +- Resource target accuracy； +- Revision correctness； +- Reference freshness awareness； +- Conflict detection rate； +- Source completeness； +- Forbidden mutation rate； +- Cross-project leakage rate； +- Memory promotion precision； +- Convergence conflict recall； +- User-visible operation explanation completeness。 + +--- + +## 十五、风险与偏差预期 + +| 风险点 | 可能偏差 | 发现方式 | 纠偏路径

十六、需要在后续阶段拍板的决策点 + +| 阶段 | 决策点 | 需要判断什么 | +|---|---|---| +| Spec | Contract 版本粒度 | 整体版本与局部编辑如何结合 | +| Spec | File 与 Attachment 关系 | 何时从消息附件晋升为 Project File | +| Spec | Artifact Head 与 Revision | 并发条件、Fork、Revert 的精确状态转换 | +| Spec | Reference 生命周期 | 创建、过期、刷新、删除的行为 | +| Spec | Thread Snapshot 结构 | 必须包含哪些结论、证据、假设和未解决问题 | +| Spec | Operation 保存期限 | 哪些长期保留，哪些只用于近期 Activity | +| Spec | Memory 授权策略

+ +--- + +## 十七、未解决的不确定性 + +1. **Thread Snapshot 何时生成。** 可以由用户主动发布、Agent 在阶段结束时提议，或系统按规则创建；首版应避免每轮自动生成。 +2. **File 新版本的格式支持。** 文本、Markdown 和代码易于处理，PDF、Office、图片需要不同的转换和验证策略。 +3. **Artifact 多文件结构。** 当前 Artifact 偏单内容；未来代码工作台可能需要 Artifact Bundle 或 Workspace，但不应阻塞单文件 Revision 首版。 +4. **Memory 的自动晋升。** 本轮只确认 Candidate—确认—生效框架，抽取、排序、衰减和冲突合并另做专题。 +5. **Activity 的实时基础设施。** 单实例可从数据库提交后推送；多实例是否采用 Postgres LISTEN/NOTIFY、Redis 或消息系统，应由部署规模决定。 +6. **团队协作权限。** 当前以单用户 Project 为主要假设；多人编辑需要进一步增加角色、资源权限和操作者身份模型。 + +这些不确定性不会推翻总体方向，可以在 Spec 或后续专题中逐步消除。 + +--- + +## 十八、进入 Spec 阶段的建议顺序 + +### S0：定义不变量 + +先把以下规则写成规范和验收条件： + +- 原始 File Version 不可变； +- Artifact Revision 不可变； +- 跨 Thread Reference 固定明确版本； +- 写入校验 Expected Head； +- Operation 不自动成为 Memory； +- 未确认 Candidate 不进入 Pinned Memory； +- 所有资源读取必须校验 Project 所有权。 + +### S1：先打通最小资源闭环 + +```text +Project Contract ++ File/File Version ++ Artifact/Artifact Revision/Head ++ Operation +``` + +目标是完成“创建—修改—查看历史—冲突—恢复—活动记录”的单 Project 闭环。 + +### S2：加入 Reference 和 Thread Snapshot + +打通： + +```text +@File Version +@Artifact Revision +@Thread Snapshot +过期提示 +显式刷新 +``` + +### S3：加入多支线 Convergence + +支持多个 Reference 的结构化汇总、来源追踪和冲突展示。 + +### S4：加入 Memory Candidate + +先做用户确认的 Project Pinned Memory，再研究自动抽取、检索和衰减。 + +### S5：扩展 Evaluation + +把资源状态、Operation 和禁止副作用加入现有 Agent Evaluation Harness。 + +--- + +## 十九、最终建议 + +ThreadChat 的 Project 应被定义为： + +> 一个以 Contract 约束工作方向、以 File 和 Artifact 承载长期资产、以 Thread 承载探索过程、以显式 Reference 连接不同分支、以 Operation 记录变化、以 Memory 沉淀已确认语义的长期 AI 工作空间。 + +最关键的产品原则不是“让 Agent 尽可能知道更多”，而是： + +```text +让 Agent 知道正确的当前状态， +知道本轮明确引用的来源， +知道哪些变化与当前任务相关， +并且让用户始终能够解释一次修改影响了什么。 +``` + +这套设计既保留 Claude/ChatGPT Projects 的连续工作体验，又利用 ThreadChat 的分叉结构解决现有线性 Project 难以解决的来源追踪、多支线研究和可靠汇总问题。 + +--- + +## 参考资料 + +### 当前代码基线 + +-

关联文档：`docs/project/01-project-workspace-research.md` +> 文档性质：对“多个研究方向存在前后依赖，最终方案藏在深层子 Thread 中”的核心用户场景做补充研究；供后续 Spec 阶段消费。 + +## 0. 30 秒结论 + +用户补充的场景说明，ThreadChat 不能只提供“在输入框里 `@` 另一个 Thread”的能力，还需要建立一套**阶段成果交接机制**： + +```text +原始讨论树 +→ 用户确认某个子 Thread 的结论 +→ 发布为某个方向的阶段成果 +→ 下游方向绑定该成果的明确版本 +→ 上游更新时，下游显示可能过期 +→ 用户显式更新、比较或保留旧版本 +→ 主线按真实依赖版本汇总 +``` + +推荐结论： + +1. **Thread 是探索过程，阶段成果才是下游依赖的稳定输入。** 下游方向不应默认依赖上游整棵讨论树。 +2. **阶段成果可以来自任意深层子 Thread。** 用户可把 A1.3 中确定的方案“发布为方向 1 的当前阶段成果”，不要求结论必须出现在方向 1 的根 Thread。 +3. **`@` 与依赖关系要分开。** `@A1` 是本轮一次性引用；“方向 2 依赖方向 1”是持续关系，需要版本绑定和过期检测。 +4. **依赖绑定固定成果版本，不实时跟随。** 方向 2 基于方向 1 的 v2 开始设计后，即使方向 1 发布 v3，也不会静默改写方向 2 的上下文，只会标记“上游已更新”。 +5. **Artifact 是正式交付物，但不应成为唯一交接方式。** 轻量研究可以直接发布结构化阶段成果；复杂方案可以同时关联一份 Markdown/代码 Artifact Revision。 +6. **主线汇总必须读取依赖关系。** 如果方向 2 使用的是方向 1 v2，而方向 1 当前已是 v3，系统必须显示版本不一致，不能假装五个方向天然一致。 +7. **阶段成果不是 Memory。** 它是有来源、有版本、有适用范围的项目成果；只有其中长期有效的决定被用户明确提升后，才进入 Project Memory 或 Pinned Memory。 + +--- + +## 一、核心用户故事 + +主线 Thread A 中，AI 提出五个存在顺序依赖的研究方向： + +```text +方向 1 → 方向 2 → 方向 3 + ├→ 方向 4 + └→ 方向 5 +``` + +用户分别创建五条 Thread： + +```text +A +├── A1：方向 1 +├── A2：方向 2 +├── A3：方向 3 +├── A4：方向 4 +└── A5：方向 5 +``` + +方向 1 的研究过程又继续分叉： + +```text +A1 +├── A1.1：方案甲 +├── A1.2：方案乙 +└── A1.3：方案丙 + ├── A1.3.1：数据模型细化 + └── A1.3.2：迁移策略细化 +``` + +最终，真正被接受的方向 1 方案可能是在 A1.3 或 A1.3.2 中确定的，而不是 A1 根 Thread 的最后一条回答。 + +随后用户进入 A2 设计方向 2。方向 2 的正确性依赖方向 1 的最终选择和改造细节，因此必须准确取得： + +- 方向 1 最终采用了什么方案； +- 哪些前提和约束已经确认； +- 哪些接口、数据模型和边界会影响方向 2； +- 结论来自哪些子 Thread、Message 和 Artifact； +- 方向 2 使用的是方向 1 的哪个版本； +- 方向 1 后来发生变化时，方向 2 是否需要重新评估。 + +这个需求不是普通“聊天记忆”，而是**有版本、有来源、有依赖关系的成果交接**。 + +--- + +## 二、为什么只有 `@Thread` 不够 + +如果 A2 中简单写： + +```text +@A1，请基于方向 1 继续设计方向 2。 +``` + +系统仍然不知道： + +1. 应读取 A1 根 Thread，还是读取其所有后代？ +2. A1.1、A1.2、A1.3 中哪一条是最终采用方案？ +3. 被否决的讨论是否应该进入上下文？ +4. 是否需要连同 A1.3.1、A1.3.2 的细节一起读取？ +5. 当前结论是否已经被用户确认？ +6. A2 后续每一轮是否都应重新读取 A1 的最新状态？ +7. A1 更新后，历史中的 A2 是否自动改变解释？ + +如果默认总结整个子树，容易把被否决方案、早期假设和最终方案混在一起；如果只读根 Thread，又可能漏掉真正的最终结论。 + +因此，`@Thread` 必须有一个稳定、可解释的默认目标： + +> 当 Thread 已有用户确认的阶段成果时，`@Thread` 默认引用该阶段成果；只有用户显式选择时，才引用原始 Thread、指定 Message、子树摘要或最近对话。 + +--- + +## 三、推荐增加“阶段成果”概念 + +### 3.1 阶段成果解决什么问题 + +阶段成果是一个从探索过程提炼出的、可供后续工作依赖的版本化结果。 + +它回答： + +```text +这个方向目前被接受的结论是什么？ +这个结论基于哪些讨论和材料？ +它会约束哪些后续方向？ +还有哪些问题没有解决？ +``` + +推荐使用产品名称： + +```text +阶段成果（Published Outcome） +``` + +它不是普通 Thread Summary： + +| 对象 | 作用 | 是否权威 | 是否需要用户确认 | +|---|---|---:|---:| +| 自动 Thread Summary | 帮助快速理解讨论 | 否 | 否 | +| 阶段成果 | 作为后续方向的正式输入 | 是，在指定范围内 | 是 | +| Artifact | 人类可阅读、编辑和交付的正式文件 | 取决于用户是否采用该 Revision | 通常是 | +| Project Memory | 在未来广泛影响 Agent 的长期事实或偏好 | 是 | 是或明确授权 | + +### 3.2 阶段成果可以从深层子 Thread 发布 + +用户在 A1.3.2 中确定最终方案后，可以执行： + +```text +发布为“方向 1”的阶段成果 +``` + +发布时，用户选择或确认： + +- 成果归属：方向 1； +- 来源范围：A1.3、A1.3.1、A1.3.2 中的指定 Message； +- 关联 Artifact：例如 `direction-1-design.md` Revision 4； +- 核心结论； +- 已确认约束； +- 对下游方向的影响； +- 未解决问题。 + +方向 1 根 Thread 随后显示： + +```text +当前阶段成果：v3 +来源：A1.3.2 +关联 Artifact：direction-1-design.md r4 +``` + +这样，用户进入 A2 时无需记住“最终方案究竟藏在哪条深层子 Thread 中”。 + +### 3.3 阶段成果需要版本，而不是原地覆盖 + +如果方向 1 后续补充研究并改变方案，应发布 v4，而不是重写 v3。 + +```text +方向 1 阶段成果 +├── v1：采用方案甲 +├── v2：改为方案丙 +├── v3：确定数据模型 +└── v4：修改迁移策略 +``` + +每个版本保留自己的来源 Thread、Message、Artifact Revision 和发布时间。 + +--- + +## 四、区分三种不同关系 + +### 4.1 一次性引用 + +用户在某条消息中输入： + +```text +@方向1 +``` + +含义是： + +> 在本轮生成中引用方向 1 当前选定的阶段成果版本。 + +它是 Message 级引用，适合临时比较、提问和综合。 + +### 4.2 持续依赖 + +用户声明： + +```text +方向 2 依赖方向 1 的阶段成果 v3。 +``` + +含义是： + +- 方向 2 的设计前提包含方向 1 v3； +- 方向 2 后续可以持续显示这一依赖； +- 当方向 1 发布 v4 时，方向 2 被标记为“上游可能已变化”； +- 系统不会自动把方向 2 切换到 v4； +- 用户需要选择保留 v3、比较 v3/v4、更新依赖或重新评估方向 2。 + +它是 Thread 或方向级关系，不只是某一条 Message 的附件。 + +### 4.3 相关关系 + +有些 Thread 只是相关，但不存在前置约束，例如： + +```text +方向 4 与方向 5 需要相互参考。 +``` + +这种关系不应触发“上游过期”的强提醒。 + +首版至少应区分： + +```text +depends_on：有方向和版本约束 +related_to：只表示相关 +``` + +是否增加 `contradicts`、`blocks`、`validates` 等关系，可留到后续阶段。 + +--- + +## 五、依赖更新必须显式，不做实时同步 + +### 5.1 为什么不能自动同步 + +假设方向 2 已基于方向 1 v3 讨论了几十条消息。方向 1 发布 v4 后，如果系统自动把方向 2 的历史上下文替换为 v4，会出现： + +- 方向 2 过去回答的前提被悄悄改变； +- 用户无法重现当时为何得出某个结论； +- 方向 2 中的一部分设计可能兼容 v4，另一部分不兼容； +- 模型无法区分“当时依据”和“现在依据”； +- 主线汇总时无法判断版本错位。 + +因此推荐： + +```text +依赖固定版本 ++ 监测上游新版本 ++ 显示过期状态 ++ 用户显式更新 +``` + +### 5.2 推荐的更新动作 + +方向 1 从 v3 更新到 v4 后，方向 2 显示： + +```text +上游“方向 1”已从 v3 更新为 v4。 +当前方向仍基于 v3。 +``` + +提供四种动作： + +1. **继续使用 v3**：当前设计保持不变； +2. **查看差异**：比较 v3 和 v4 对方向 2 的影响； +3. **更新依赖**：从当前时点开始使用 v4，并留下更新记录； +4. **创建评估分支**：从方向 2 当前状态分叉，研究迁移到 v4 的影响。 + +不允许静默更新。 + +--- + +## 六、Artifact 在交接中的角色 + +### 6.1 不强制每个方向都生成 Artifact + +如果每一次支线研究都必须先写 Markdown，用户成本会很高。简单方向可以直接发布结构化阶段成果。 + +因此推荐两级模式： + +```text +轻量交接：阶段成果 +正式交接：阶段成果 + Artifact Revision +``` + +### 6.2 什么时候建议生成 Artifact + +以下情况应优先生成 Artifact： + +- 方案包含较长的设计说明； +- 下游需要精确接口、代码、表格或迁移步骤； +- 结论需要人工编辑； +- 需要导出或外部分享； +- 多个下游方向会反复引用； +- 需要对比 Revision Diff。 + +### 6.3 Artifact 不是阶段成果本身 + +Artifact 是内容载体；阶段成果表达的是“Project 当前采用什么”。 + +例如： + +```text +Artifact：direction-1-design.md r4 +阶段成果：方向 1 v3，采用该 Artifact r4，并附带两条尚未解决的风险 +``` + +Artifact 后来生成 r5，不代表方向 1 自动采用 r5。用户需要明确发布新的阶段成果，或者明确把阶段成果更新为引用 r5。 + +这能避免“文件编辑了一次，所有依赖 Thread 都被静默改变”。 + +--- + +## 七、`@` 的推荐解析语义 + +### 7.1 `@方向1` + +默认解析顺序： + +1. 方向 1 当前已发布阶段成果； +2. 如果没有，显示可选择的自动 Summary； +3. 用户可以改为引用指定 Thread、子树、Message 或 Artifact。 + +系统应在输入框中显示结构化引用卡，而不是只留下纯文本标题： + +```text +@方向1 · 阶段成果 v3 · 固定版本 +``` + +### 7.2 `@A1.3.2` + +表示用户明确引用某条深层 Thread。 + +推荐提供： + +- 当前阶段成果； +- 最近一轮； +- 指定 Message； +- 自动子树摘要； +- 从该 Thread 发布新的阶段成果。 + +### 7.3 `@direction-1-design.md` + +表示引用 Artifact。必须显示具体 Revision： + +```text +@direction-1-design.md · r4 +``` + +用户可以主动选择“最新 Revision”，但发送消息时仍解析并固定为一个明确 Revision，避免历史引用漂移。 + +--- + +## 八、方向 2 如何获得方向 1 的上下文 + +方向 2 第一次绑定方向 1 v3 时，系统应生成一个受控的交接上下文，至少包含： + +```text +方向 1 阶段成果 v3 +- 核心结论 +- 已确认约束 +- 对方向 2 的明确影响 +- 关联 Artifact Revision +- 未解决问题 +- 来源 Thread / Message +``` + +不应默认注入： + +- 方向 1 全部原始聊天； +- 已否决方案的完整内容； +- 无关工具调用； +- 所有子 Thread 的重复讨论； +- 整个 Project 的操作日志。 + +方向 2 的初始依赖版本应成为其可重现的工作前提。上游新版本通过过期状态和显式更新进入，而不是回写历史。 + +--- + +## 九、五个方向汇总回主线 + +主线 A 最终汇总 A1—A5 时，系统不能只读取“每个方向当前最新成果”，还需要读取每个方向实际使用的依赖版本。 + +例如： + +```text +方向 1 当前成果：v4 +方向 2 当前成果：v2，但它基于方向 1 v3 +方向 3 当前成果：v1，基于方向 2 v2 +``` + +这时汇总系统必须指出： + +```text +方向 2 仍基于方向 1 v3，而方向 1 当前已是 v4。 +方向 2 和其下游方向 3 可能需要重新评估。 +``` + +推荐的汇总顺序： + +1. 固定每个方向要采用的阶段成果版本； +2. 读取依赖关系； +3. 按依赖顺序检查版本是否一致； +4. 标记过期依赖、冲突和缺失成果； +5. 用户决定先重新评估，还是带风险继续汇总； +6. 生成主线 Convergence Bundle； +7. 主线继续讨论或生成综合 Artifact。 + +因此，依赖关系不仅帮助 A2 读取 A1，也帮助最终主线判断五个方向是否真的可以被合并。 + +--- + +## 十、与 Operation、Memory、Contract 的边界 + +### 10.1 Operation + +以下动作应形成 Project Operation： + +```text +thread.outcome.published +thread.outcome.superseded +thread.dependency.added +thread.dependency.marked_stale +thread.dependency.updated +artifact.revision.adopted_by_outcome +convergence.created +``` + +Operation 用于审计、活动展示和过期状态计算，不直接作为长期 Prompt 内容。 + +### 10.2 Memory + +阶段成果中的某项决定可能具有 Project 长期价值，例如： + +```text +所有 Artifact 更新必须创建不可变 Revision。 +``` + +但它不会因为出现在阶段成果中就自动成为 Memory。 + +推荐流程： + +```text +阶段成果中的决定 +→ Agent 建议“提升为 Project Memory” +→ 用户确认 +→ Active / Pinned Memory +``` + +### 10.3 Contract + +只有真正长期约束整个 Project 的内容，才应写入 Contract，例如： + +```text +原始 File 不允许被 Agent 静默覆盖。 +``` + +某个方向的具体实现方案通常属于阶段成果或 Project Decision，不应不断改写 Contract。 + +--- + +## 十一、Agent 行为边界 + +### 11.1 Agent 可以做什么 + +- 根据用户选择的 Message 和 Artifact 草拟阶段成果； +- 识别某个子 Thread 的结论可能影响哪些下游方向； +- 建议建立 `depends_on`； +- 在上游更新后分析差异和影响范围； +- 为主线生成依赖一致性检查； +- 建议将稳定决定提升为 Memory。 + +### 11.2 Agent 不能静默做什么 + +- 自动把一条模型回答发布为权威阶段成果； +- 自动把下游依赖切换到上游最新版本； +- 自动用最新 Artifact Revision 替换历史引用； +- 自动把某条支线结论写入 Project Memory； +- 自动认定一个深层子 Thread 是最终采用方案； +- 在冲突未解决时声称所有方向已经一致。 + +--- + +## 十二、首版产品流程建议 + +### 12.1 发布阶段成果 + +在任意 Thread 或 Artifact 中提供： + +```text +发布为阶段成果 +``` + +发布预览至少显示： + +- 归属方向； +- 核心结论； +- 采用的来源； +- 关联 Artifact Revision； +- 对下游的影响； +- 未解决问题。 + +用户确认后才生效。 + +### 12.2 在下游引用 + +A2 输入： + +```text +@方向1，基于这个结果继续设计方向 2。 +``` + +引用卡显示： + +```text +方向 1 · 阶段成果 v3 · 固定版本 +``` + +用户可选择“同时建立持续依赖”。 + +### 12.3 上游更新 + +方向 1 发布 v4 后，A2 显示： + +```text +依赖已过期：当前使用 v3，上游最新为 v4。 +``` + +用户选择比较、更新、保留或创建评估分支。 + +### 12.4 回到主线汇总 + +A 中选择 A1—A5，系统先展示： + +- 每个方向的成果版本； +- 依赖链； +- 过期关系； +- 冲突和缺失结果。 + +确认后再进入综合讨论或生成总方案 Artifact。 + +--- + +## 十三、实施优先级的调整 + +这个场景提高了以下能力的优先级： + +### P0 + +1. 结构化 `@Thread/@Artifact` 引用； +2. 引用固定 Snapshot/Revision； +3. 从指定 Thread 和 Message 生成阶段成果草稿； +4. 用户确认后发布阶段成果； +5. `@Thread` 默认引用阶段成果。 + +### P1 + +1. `depends_on` 关系； +2. 上游新版本后的过期提示； +3. 阶段成果关联 Artifact Revision； +4. 更新依赖和创建评估分支； +5. 主线依赖一致性检查。 + +### P2 + +1. 自动识别潜在下游影响； +2. 多方向 Convergence Bundle； +3. 更丰富的关系类型； +4. 从阶段成果推荐 Memory Candidate； +5. 依赖图可视化。 + +这意味着，完整自动 Memory 系统不应排在 `@`、阶段成果和依赖交接之前。对于用户描述的真实工作方式，**先让成果能够被可靠地发布、引用和传递，比先让 Agent 自动记住更多内容更重要。** + +--- + +## 十四、核心风险与验证 + +| 风险 | 可能偏差 | 发现方式 | 纠偏路径 | +|---|---|---|---| +| 自动 Summary 被误当成权威结论 | 下游使用了未确认方案 | 检查成果是否有用户确认状态 | 自动 Summary 与 Published Outcome 强制区分 | +| `@Thread` 展开整个子树 | 被否决方案和重复内容污染上下文 | 记录实际引用范围 | 默认只引用已发布阶段成果 | +| 上游更新自动影响下游 | 历史无法重现 | 重放下游生成使用的依赖版本 | 固定版本并显式更新 | +| Artifact Head 自动替换阶段成果中的 Revision | 文件一次编辑改变多个 Thread | 检查引用 Revision 是否漂移 | 发布时固定 Artifact Revision | +| 深层子 Thread 的成果无法归属上层方向 | 用户仍需记忆成果藏在哪里 | 测试从 A1.3.2 发布到 A1 | 允许跨层发布并显示来源 | +| 汇总忽略依赖版本错位 | 生成内部不一致的总方案 | 汇总前执行依赖一致性检查 | 阻止无提示合并，显式列出风险 | +| 阶段成果被滥用为 Memory | 大量短期结论污染所有 Thread | 审计成果与 Memory 写入链路 | 需要独立提升动作 | + +--- + +## 十五、建议新增的评测场景 + +### 场景 1：深层子 Thread 发布成果 + +```text +A1.1 与 A1.2 被否决；A1.3.2 确定最终方案。 +用户将 A1.3.2 发布为方向 1 成果。 +``` + +断言： + +- 方向 1 当前成果指向新版本； +- 来源包含 A1.3.2； +- 被否决方案不会成为成果正文； +- 原始 Thread 历史不被改写。 + +### 场景 2：下游固定依赖 + +```text +方向 2 基于方向 1 v3 开始。 +方向 1 后来发布 v4。 +``` + +断言： + +- 方向 2 仍记录 v3； +- 显示上游已更新； +- 不自动注入 v4； +- 更新依赖需要显式操作。 + +### 场景 3：Artifact Revision 不漂移 + +```text +方向 1 v3 采用 Artifact r4。 +Artifact 后来生成 r5。 +``` + +断言： + +- 方向 1 v3 仍引用 r4； +- r5 不自动替换； +- 可以发布方向 1 v4 来采用 r5。 + +### 场景 4：主线发现版本错位 + +```text +方向 2 基于方向 1 v3；方向 1 当前为 v4。 +用户在 A 中汇总五个方向。 +``` + +断言： + +- 系统发现版本错位； +- 清楚指出受影响的方向； +- 不声称汇总结果完全一致； +- 用户可选择先重新评估或带风险继续。 + +### 场景 5：一次性引用不自动建立依赖 + +```text +A2 中通过 `@方向1` 临时比较方案，但用户没有选择“建立依赖”。 +``` + +断言： + +- 当前 Message 固定引用成果版本； +- A2 不产生持续依赖关系； +- 上游更新不触发强过期状态。 + +--- + +## 十六、进入 Spec 前的建议决策 + +这次补充场景使以下决策应在 Spec 最前面明确： + +1. “方向”是否只是一个被标记的 Thread，还是新增独立 Workstream 对象； +2. 阶段成果归属于 Thread、方向，还是通用 Project Scope； +3. 深层子 Thread 发布成果时，由谁选择来源范围； +4. `@Thread` 在没有阶段成果时的回退行为； +5. 持续依赖是否需要用户显式勾选； +6. 依赖更新后，是向当前 Thread 追加一条结构化上下文，还是建立新的基线； +7. 主线汇总遇到过期依赖时，是阻止、警告还是允许带风险继续。 + +Research 阶段的推荐方向是： + +> 首版不必新增完整 Workstream 管理系统。优先把“方向”实现为一个可被标记的 Thread 范围，并允许其阶段成果来源于任意后代 Thread。等依赖、负责人、状态、里程碑等需求真正出现后，再评估是否提升为独立 Workstream 对象。 + +--- + +## 十七、最终判断 + +用户描述的真实场景表明，ThreadChat 的核心价值不只是“能分叉”，而是： + +```text +能在深层分叉中完成探索， +把被接受的结果发布回一个稳定方向， +让后续方向按明确版本继续， +并在主线汇总时知道每一步究竟基于什么。 +``` + +因此推荐把产品主链路从： + +```text +Fork → Chat → @Thread +``` + +升级为： + +```text +Fork +→ Explore +→ Publish Outcome +→ Reference / Depend +→ Detect Staleness +→ Re-evaluate +→ Converge +``` + +这套链路比“把更多聊天自动塞进 Memory”更能解决复杂 Project 的长期连续性和可预测性问题，也是 ThreadChat 相比线性聊天 Project 最有机会形成差异化的部分。 From 7875a99844e5bb6eb43f7afa0f08151c0e6bc623 Mon Sep 17 00:00:00 2001 From: zilin Date: Mon, 31 Aug 2026 04:11:15 +0800 Subject: [PATCH 040/141]

文档性质：汇总当前讨论结果，明确已经确定的产品边界、暂定方案和后续需要深度调研的问题。本文供下一轮 Research 和后续 Spec 阶段消费，不定义最终数据库字段和接口。 + +## 0. 本轮结论 + +当前方案从较复杂的“阶段成果发布、持续依赖、依赖过期传播、专门汇总对象”收敛为更小的产品模型： + +```text +普通 Thread 探索 +→ 生成 Outcome Markdown Artifact +→ 在其他 Thread 中结构化 @ 引用 +→ 模型基于明确引用继续推理或综合 +→ 必要时生成新的 Outcome / 最终 Artifact +``` + +首版核心只保留两项新能力： + +1. **结构化 `@` 引用**：支持引用 `Thread`、`Message`、`Artifact` 三类实体。 +2. **Outcome Markdown**：复用现有 Markdown Artifact 工具和基础设施，为“当前结论、方案交接、阶段总结”提供更严格的工具描述和生成规则。 + +首版明确不建立： + +- `depends_on` 持续依赖关系； +- 独立的 `ThreadOutcome` 领域实体； +- Thread “发布完成”或“已交接”状态； +- 专门的 Convergence / 汇总对象； +-

`depends_on`、独立阶段成果实体和专门汇总流程的建议做了收敛修正。02 文档保留为问题探索记录，当前产品方向以本文为准。 + +--- + +## 一、当前讨论结果 + +### 1.1 Project 的总体定位 + +Project 不是简单的聊天分组，而是一个长期 AI 工作空间。当前仍采用以下总体结构： + +```text +Project +├── Contract +│ ├── Target +│ ├── Instructions +│ └── Pinned Memory +├── Files +├── Artifacts +├── Threads / Messages +├── Structured References +├── Operations / Activity +└── Memory（后续专题） +``` + +其中： + +- **Contract** 提供项目级方向和稳定规则； +- **Files** 是用户上传的原始资料； +- **Artifacts** 是对话中生成、可跨 Thread 复用的工作成果； +- **Reference** 是把其他 Thread、Message、Artifact 带入当前消息的显式机制； +- **Operation** 记录发生过的业务操作； +- **Memory** 保存未来应继续影响 Agent 的事实、偏好和决策。 + +Operation 不等于 Memory，Outcome 也不自动等于 Memory。 + +### 1.2 Contract + +当前认可的产品结构仍是： + +```text +Project Contract +├── Target +├── Instructions +└── Pinned Memory +``` + +- `Target` 是项目灯塔，描述最终要达成什么； +- `Instructions` 是项目级工作方式和约束； +- `Pinned Memory` 是用户明确要求长期保留的重要事实、偏好和决策。 + +Pinned Memory 在产品界面中可以属于 Contract，但底层是否与 Target、Instructions 共用同一种版本机制，仍需后续专题判断。 + +### 1.3 Files + +Files 是用户上传的原始资料，例如 PDF、Word、Excel、Markdown、图片、代码和数据文件。 + +当前原则： + +1. 用户上传的原始 File Version 不由 Agent 原地覆盖； +2. 用户更新资料时，倾向于在同一逻辑 File 下增加新版本； +3. Agent 对原始资料进行改写时，通常生成 Derived Artifact； +4. 历史消息引用的是当时确定的 File Version，不随最新版静默变化。 + +File 的详细版本、替换、删除和派生语义仍待深度调研。 + +### 1.4 Artifacts + +Artifacts 是对话中生成的长期成果，例如： + +- Markdown 文档； +- JavaScript / TypeScript； +- HTML / CSS； +- Python 和其他代码文件； +- JSON、配置文件； +- 后续可能支持的表格和可交互预览。 + +当前倾向是： + +```text +Artifact = 稳定逻辑身份 +Artifact Revision = 一次不可变内容版本 +Artifact Head = 当前最新版 +``` + +该模型能让 `@Artifact` 固定到明确版本，并避免多个 Thread 静默覆盖彼此。 + +但首版 Artifact Revision 的具体范围、并发策略和用户更新体验仍需专题调研。 + +--- + +## 二、为什么不先做 `depends_on` + +用户的真实场景是： + +```text +主线 A 提出五个方向 +→ 方向 1 在深层子 Thread 中确定方案 +→ 方向 2 需要使用方向 1 的结果 +→ 最后回到 A 综合多个方向 +``` + +最初考虑通过： + +```text +方向 2 depends_on 方向 1 v3 +``` + +建立持续依赖关系。但这会迅速引入： + +- 依赖创建、解除和替换； +- 上游更新后的过期状态； +- 用户保留旧版本或升级到新版本； +- 依赖环检测； +- 传递依赖； +- Thread 归档、Artifact Fork 后的关系处理； +- 历史消息与当前依赖版本不一致； +- 大量组合测试。 + +对用户而言，“一次性引用”和“持续依赖”也很难直观区分。 + +当前判断是： + +> 用户真正需要的是把某个已整理结果可靠地带到另一个 Thread，而不是先管理一张项目依赖图。 + +因此首版改为： + +```text +在上游生成 Outcome Artifact +→ 下游通过 @Artifact 明确引用 +``` + +如果上游 Outcome 后来生成新 Revision，历史引用继续固定旧 Revision。用户需要新版本时再次 `@`，或者同时引用新旧两个版本进行比较。 + +未来若用户频繁需要“每轮持续携带同一个 Artifact”，优先考虑更直观的： + +```text +固定到当前 Thread +``` + +而不是直接引入 `depends_on`。 + +--- + +## 三、结构化 `@` 引用 + +### 3.1 支持的三类实体 + +MVP 支持： + +```text +@Thread +@Message +@Artifact +``` + +不把 `@` 当成纯文本，也不让模型自行决定调用哪个读取工具。 + +推荐链路： + +```text +用户在 Composer 输入 @ +→ 前端搜索当前 Project 中可引用实体 +→ 用户选择明确对象 +→ Composer 保存结构化引用 +→ Send Command 提交文本和引用 +→ 服务端校验归属与权限 +→ 服务端固定 Message / Thread Snapshot / Artifact Revision +→ Context Compiler 按顺序展开 +→ 模型收到明确、可重放的上下文 +``` + +这样引用目标由用户确定，而不是依赖模型是否正确调用工具。 + +### 3.2 `@Message` + +语义：引用一条明确 Message。 + +适合： + +- 一条准确结论； +- 一段代码； +- 一次模型解释； +- 不值得生成独立 Artifact 的轻量信息。 + +当前倾向：历史引用固定原 Message。即使该 Message 后续通过 Retry 或 Edit 产生新版本，旧引用也不自动切换。 + +待调研： + +- 是否支持引用整条 Message 和选中段落两种模式； +- 当前已有 Quote/TextAnchor 是否可以直接复用； +- 被 supersede 的 Message 在引用搜索和历史展示中如何处理。 + +### 3.3 `@Artifact` + +语义：引用一个明确的 Artifact Revision。 + +适合： + +- Outcome； +- 方案文档； +- 研究报告； +- Spec； +- 代码文件； +- 最终交付物。 + +UI 可以允许用户选择“最新版”，但发送消息时必须解析为确定的 Revision。 + +例如用户看到： + +```text +@方向1方案总结.md · 最新版 +``` + +消息落库时保存： + +```text +artifactId +artifactRevisionId +``` + +历史消息不会随着 Artifact Head 更新而变化。 + +### 3.4 `@Thread` + +语义需要保持克制。 + +当前建议： + +1. 只引用目标 Thread 自己的有效时间线； +2. 不自动递归包含其子 Thread； +3. 发送时冻结为 Thread Snapshot； +4. Thread 后续新增消息不改变旧 Snapshot； +5. Thread 太长时，不应静默生成不可见摘要冒充完整 Thread。 + +长 Thread 的可选处理方式待调研，候选包括： + +- 最近一轮； +- 当前有效时间线； +- 用户选择若干 Message； +- 显式生成 Outcome Artifact； +- 用户可见并确认的 Thread 摘要。 + +当前产品方向优先鼓励： + +> 轻量信息引用 Message；复杂交接生成 Outcome Artifact；`@Thread` 作为方便但边界明确的补充能力。 + +### 3.5 多引用综合 + +用户可以在主线 A 中输入： + +```text +@方向1总结.md +@方向2总结.md +@方向3结论.md +@方向4方案.md +@方向5风险.md + +综合以上结果，形成最终方案。 +``` + +这只是一次普通模型任务： + +```text +当前 Thread 上下文 ++ 多个结构化引用 ++ 用户综合指令 +``` + +模型可以直接回复，也可以继续调用 Markdown Artifact 工具生成最终文档。 + +首版不建立专门的“汇总对象”或“合并状态机”。 + +--- + +## 四、Outcome 的产品定义 + +### 4.1 Outcome 不是新领域实体 + +Outcome 的最小定义是： + +```text +一个用途为阶段总结的普通 Markdown Artifact +``` + +例如： + +```text +Artifact kind = markdown +Artifact metadata.purpose = outcome +``` + +Outcome 不意味着： + +- Thread 已完成； +- Thread 已发布； +- 用户正式接受了全部内容； +- 当前方向进入某种状态； +- 必须创建 Handoff 记录； +- 必须绑定用户手动选择的 Message ID； +- 必须生成依赖关系。 + +用户只需像普通聊天一样说： + +```text +帮我把当前已确定的方案总结成 Markdown。 +``` + +系统生成一个可在 Project 中复用的 Markdown Artifact。 + +### 4.2 Outcome 与交接（Handoff）的关系 + +语义上建议这样理解： + +```text +Outcome Artifact += 被交接的工作成果 + +@ Reference += 传递成果的方式 + +Handoff += 上游创建成果，并由下游明确引用的完整用户行为 +``` + +因此： + +```text +生成 Outcome +≠ 已完成交接 +``` + +只有它在其他 Thread 中被 `@` 使用后，才发生了基于 Artifact 的交接。 + +首版不需要 Handoff 数据库实体或状态机。 + +### 4.3 Outcome 工具如何复用 Markdown 工具 + +当前建议：模型侧可以拥有一个更明确的工具别名或专用描述，但底层完全复用 Markdown Artifact 实现。 + +候选方式： + +#### 方式 A：相同工具名，动态切换描述 + +```text +createMarkdownArtifact +``` + +普通文档请求使用普通描述；Outcome 请求使用严格的总结描述。 + +优点：工具数量最少。 +风险：工具意图和评测记录不够清晰。 + +#### 方式 B：模型侧独立工具别名，底层共用实现 + +```text +createMarkdownArtifact +createOutcomeMarkdownArtifact +``` + +两者使用相同输入： + +```text +title +content +``` + +两者复用： + +- 同一 Zod Schema； +- 同一流式工具输入处理； +- 同一 Artifact 创建服务； +- 同一 Markdown UI； +- 同一 Revision 基础设施。 + +差别只有： + +- 工具名称； +- 工具描述； +- `metadata.purpose = outcome`； +- 单独的 Outcome 评测。 + +当前更倾向方式 B，但需要通过实验验证两个近似工具是否会增加模型误调用。为降低冲突，同一轮通常只挂载其中一个工具。 + +--- + +## 五、Outcome 为什么容易总结错误 + +普通“总结聊天”很容易出现： + +1. 把 Assistant 的建议写成用户已确认决定； +2. 把已经被后续否决的旧方案写成当前方案； +3. 面对冲突时擅自拍板； +4. 为了文档完整补充对话中没有的设计； +5. 混淆继承背景、当前分支结论和显式引用资料； +6. 生成流水账，遗漏真正影响后续工作的约束； +7. 忽略较早但已经明确确认的关键决定。 + +因此 Outcome 不是普通摘要，而更接近： + +```text +从当前有效上下文中提取当前权威工作状态 +``` + +### 5.1 默认总结范围 + +当前暂定范围： + +```text +当前 Thread 的冻结继承上下文 ++ 当前 Thread 的有效时间线 ++ 当前用户消息显式 @ 的 Message / Thread Snapshot / Artifact Revision +``` + +默认不包括： + +- 未显式引用的兄弟 Thread； +- 当前 Thread 的子 Thread； +- Project 中全部其他 Artifacts； +- 未显式引用的 Files； +- 已被 supersede 的旧 Message； +- 失败生成； +- 模型自行推测的 Project 信息。 + +用户不需要手动选择 Message ID，服务端根据当前有效上下文自动确定范围。 + +### 5.2 信息权威顺序 + +暂定判断顺序： + +```text +用户最新明确更正 +> +用户明确确认的选择 +> +后续讨论明确以其为前提的工作方向 +> +Assistant 提出的方案建议 +> +模型为了补全结构所做的推断 +``` + +后两类不能直接写成“已确认”。 + +尤其需要坚持： + +> Assistant 提出建议后，用户没有反驳，不等于用户已经确认。 + +### 5.3 Outcome 的信息分类 + +推荐至少区分： + +1. 已确认结论； +2. 已确认的改造细节； +3. 对后续步骤的约束； +4. 当前工作假设； +5. 已否决或已被替代的方案； +6. 未解决问题； +7. 来源说明。 + +某个分类没有足够依据时，可以省略或明确写“当前没有已确认内容”，不能为了填满模板而编造。 + +### 5.4 推荐 Markdown 结构 + +```markdown +# 阶段总结：方向 1 + +## 本次总结范围 + +## 已确认结论 + +## 已确认的改造细节 + +## 对后续步骤的约束 + +## 当前工作假设 + +## 已否决或已被替代的方案 + +## 未解决问题 + +## 来源说明 +``` + +该结构是推荐模板，不要求每个章节都必须存在。 + +### 5.5 生成前校验 + +Outcome 工具描述应要求模型在生成前完成： + +```text +冲突检查： +是否把两个互相冲突的方案都写成已确认？ + +时序检查： +是否使用了已被后续更正或替代的旧结论？ + +证据检查： +每条“已确认”内容是否确实能从当前上下文得到支持？ +``` + +不要求向用户展示模型完整思考过程，最终只输出校验后的文档。 + +--- + +## 六、Provenance：首版记录多少来源信息 + +用户不需要操作 Message ID，但系统仍应自动保留基础来源。 + +当前 Artifact 已经拥有： + +```text +projectId +sourceMessageId +``` + +这能回答： + +- Artifact 属于哪个 Project； +- 它由哪次 Assistant Message 生成； +- 它来自哪个 Thread； +- 生成失败或内容异常时如何定位。 + +对于 Outcome MVP，暂时不要求用户手动选择： + +```text +sourceMessageIds +sourceRange +acceptedByUser +publishedAt +handoffState +directionId +``` + +但仍需深度调研： + +1. 仅 `sourceMessageId` 是否足够支持后续来源解释； +2. 是否应自动保存本轮使用的结构化 Reference IDs； +3. 是否需要记录 Outcome 的输入 Thread Snapshot； +4. 是否需要为每条已确认结论建立 Evidence Mapping； +5. 来源信息应展示给用户多少，避免 UI 过重。 + +--- + +## 七、Operations 与 Memory + +### 7.1 Operation + +建议继续区分业务操作和记忆。 + +可能记录的操作包括： + +```text +artifact.created +artifact.revision.created +reference.created +file.version.added +contract.updated +memory.pinned +``` + +Operation 用于： + +- 用户活动记录； +- 来源审计； +- UI 实时更新； +- Agent 在需要时了解近期相关变化。 + +EventSource / SSE 只负责把操作结果实时传到浏览器，不是权威存储，也不会自动让 LLM 知道用户操作。 + +### 7.2 Memory + +Outcome 或一次 `@` 引用不会自动写入 Memory。 + +后续 Memory 专题至少需要区分： + +```text +Personal Memory +Project Pinned Memory +Project Working Memory +Thread Memory +Artifact-derived Knowledge +Current Working Context +``` + +当前只确定： + +- Pinned Memory 需要用户明确确认； +- Agent 可以提出 Memory Candidate； +- Operation 不能直接当成 Memory； +- Outcome 中的某条长期决策可以被用户另行提升为 Project Memory。 + +--- + +## 八、MVP 用户故事 + +### 8.1 深层子 Thread 形成方向 1 的结果 + +```text +A +└── A1 + └── A1.3 + └── A1.3.2 +``` + +用户在 A1.3.2 中说： + +```text +请把当前已经确定的方案、改造细节、 +对后续步骤的约束和未解决问题整理成 Markdown。 +``` + +模型生成： + +```text +方向1方案总结.md · r1 +purpose = outcome +``` + +### 8.2 方向 2 使用方向 1 的结果 + +用户进入 A2： + +```text +@方向1方案总结.md · r1 + +基于这个方案设计方向 2。 +``` + +这条消息永久绑定 r1。 + +### 8.3 方向 1 后来更新 + +用户继续研究并生成： + +```text +方向1方案总结.md · r2 +``` + +A2 的历史消息仍然引用 r1。 + +用户需要重新评估时可以： + +```text +@方向1方案总结.md · r1 +@方向1方案总结.md · r2 + +比较两个版本，并判断方向 2 是否需要调整。 +``` + +### 8.4 主线综合多个方向 + +用户回到 A： + +```text +@方向1方案总结.md · r2 +@方向2方案总结.md · r3 +@方向3调研结论.md · r1 +@方向4方案总结.md · r2 +@方向5风险分析.md · r1 + +综合成最终实施方案，并生成 Markdown 文档。 +``` + +模型正常综合并生成新的 Artifact。 + +该流程不需要独立汇总实体、依赖图或 Thread 状态机。 + +--- + +## 九、当前已经确定的决策 + +### D1. Project Contract + +继续采用： + +```text +Target + Instructions + Pinned Memory +``` + +### D2. 原始 Files + +原始 File Version 不由 Agent 原地覆盖。 + +### D3. Outcome + +Outcome 是带 `purpose=outcome` 的普通 Markdown Artifact，不是独立领域实体。 + +### D4. Outcome 的用户操作 + +生成 Outcome 是一次普通用户消息和普通 Artifact 工具调用，不要求用户选择 Message ID，不改变 Thread 状态。 + +### D5. Handoff + +Handoff 是“上游生成 Artifact、下游通过 `@` 使用”的行为语义，不建立 Handoff 实体。 + +### D6. Reference + +MVP 支持： + +```text +@Thread +@Message +@Artifact +``` + +引用必须结构化保存，并由服务端验证。 + +### D7. 历史稳定性 + +`@Artifact` 固定明确 Revision；`@Thread` 固定明确 Snapshot；`@Message` 固定明确 Message。 + +### D8. 汇总 + +多方向汇总是模型针对多个结构化引用执行的普通综合任务，不建立专门 Convergence 实体。 + +### D9. 依赖关系 + +首版不实现 `depends_on` 和项目依赖图。 + +### D10. Memory + +Outcome、Reference 和 Operation 不自动进入长期 Memory。 + +--- + +## 十、当前暂定、需要验证的假设 + +### H1. Outcome 工具 + +模型侧使用独立的 `createOutcomeMarkdownArtifact`，底层完全复用 Markdown Artifact 实现，可能比动态修改同一个工具描述更容易评测和观察。 + +### H2. 工具挂载 + +同一轮只挂载普通 Markdown 工具或 Outcome Markdown 工具中的一个，以减少近似工具选择冲突。 + +### H3. `@Thread` + +`@Thread` 默认只引用目标 Thread 自身有效时间线，不递归包含子 Thread。 + +### H4. Thread Snapshot + +Thread 引用在发送时冻结，不跟随目标 Thread 后续新增内容。 + +### H5. Artifact Revision + +Artifact 需要稳定身份和不可变 Revision，才能让历史 `@Artifact` 可重放。 + +### H6. Outcome 范围 + +Outcome 默认使用当前 Thread 有效上下文和本轮显式 References，不自动读取 Project 中其他内容。 + +### H7. Outcome 正确性 + +通过严格的工具描述、分类模板、时序和冲突检查，可以在不增加复杂工作流的情况下达到可接受正确率。 + +以上假设都需要通过专题调研或最小实验验证。 + +--- + +## 十一、待深度调研的问题 + +### R1. Outcome 正确性与评测方法【P0，深度】 + +核心问题： + +1. 模型如何可靠区分“用户确认”“当前假设”“Assistant 建议”和“已否决方案”？ +2. 分支中最新决定如何覆盖继承上下文的旧决定？ +3. 多个明确引用内容冲突时，Outcome 应如何表达？ +4. 单次工具调用是否足够，还是需要“先提取结构化状态，再渲染 Markdown”的两步方案？ +5. 是否需要为结论附带轻量证据引用？ +6. 不同模型上的稳定性差异有多大？ + +建议验证： + +- 建立 30—50 个合成对话案例； +- 覆盖更正、否决、未确认、分支覆盖、引用冲突和信息缺失； +- 比较普通摘要 Prompt、严格 Outcome Prompt、两步结构化提取三种方案； +- 评估已确认结论准确率、错误确认率、遗漏率和幻觉率。 + +### R2. `@` Composer 与用户交互【P0，深度】 + +核心问题： + +1. 如何在同一个 `@` 搜索框中清楚区分 Thread、Message 和 Artifact？ +2. Message 如何被用户找到：按当前页面选中、按搜索结果，还是按引用最近内容？ +3. Artifact 是否展示 Head、Revision、来源 Thread 和类型？ +4. 用户选择“最新版”时，发送前如何让其知道最终固定的是哪个 Revision？ +5. 多个 References 如何排序、删除和预览？ +6. 移动端 Composer 的交互如何保持可用？ + +建议验证： + +- 做交互原型； +- 用 5—8 个真实任务测试用户是否能正确选择目标实体； +- 重点观察同名 Artifact、深层 Thread 和长标题场景。 + +### R3. `@Thread` 的范围与长上下文处理【P0，深度】 + +核心问题： + +1. 默认是完整有效时间线、最近一轮还是用户选择范围？ +2. 长 Thread 超出预算时如何处理，才能避免静默丢信息？ +3. Thread Snapshot 是否保存 Message IDs，还是保存规范化内容副本？ +4. Snapshot 中的附件、工具结果和 Artifact References 如何展开？ +5. 是否允许用户显式选择“包含子 Thread”，以及是否值得首版支持？ + +建议方向： + +- 首版不递归子 Thread； +- 对过长 Thread 引导用户生成 Outcome，或显式选择 Message； +- 不在后台静默总结整个 Thread 冒充原文。 + +### R4. Reference 的持久化与上下文装配【P0，深度】 + +核心问题： + +1. Reference 保存为 Message Part、独立关联表，还是两者结合？ +2. 客户端提交哪些 ID，服务端如何验证并冻结版本？ +3. 上下文中引用内容放在用户消息之前还是作为独立服务端 Context？ +4. 多引用如何去重、排序和控制 Token 预算？ +5. 被引用 Message/Artifact 后续归档或删除时，历史如何重放？ +6. 如何禁止跨用户、跨 Project 泄漏？ + +需要结合当前： + +- `ThreadChatUIMessage.parts`； +- `compileModelContext`； +- `forkContext`； +- `conversationCommands`； +- Attachment 解析链路。 + +### R5. Artifact Revision 生命周期【P0，深度】 + +核心问题： + +1. 一个 Artifact 的稳定身份如何创建？ +2. “更新这个文档”默认产生新 Revision，还是创建新 Artifact？ +3.

number +``` + +建议限制： + +```ts +PROJECT_TARGET_MAX_CHARS = 4_000 +PROJECT_INSTRUCTIONS_MAX_CHARS = 20_000 +``` + +Target 和 Instructions 允许为空；服务端统一 trim，空字符串落库为 `null`。`contractVersion` 从 `0` 开始，每次成功保存整份 Contract 后加一。 + +本次不建立 `project_contract_revisions`。用户需要的是先获得稳定的项目方向，不是审计每次 Contract 修改。递增版本只用于并发控制和生成快照标识，不提供历史浏览或回退。 + +弃选把 Target、Instructions、Pinned Memory 存为一个自由 JSON：当前两类字段的语义、限制和模型注入位置明确，独立列更便于校验、查询和迁移；Pinned Memory 尚未进入 MVP，不应提前污染 Contract 结构。 + +### D2：Contract 使用显式保存与乐观并发，不使用无提示自动覆盖 + +新增幂等 `UpdateProjectContractCommand`： + +```ts +{ + commandId: UUID + expectedContractVersion: number + target: string + instructions: string +} +``` + +服务端在锁定 owner-scoped Project 后检查 `expectedContractVersion`。版本不一致时返回可恢复的 state conflict，客户端保留本地草稿并提示用户重新加载最新设置，不能静默以旧页面覆盖新值。 + +Project Panel 使用“编辑 → 保存/取消”模式。保存成功后以服务端 DTO 替换客户端状态。Contract 不采用逐字符自动保存，避免用户尚未完成编辑时就改变后续模型行为。 + +Archived Project 只能查看 Contract；除取消归档外，不接受 Contract、File 或对话写入。 + +### D3：Target 与 Instructions 作为服务端拥有的 Project Context + +Generation 初始化时读取 Project 的当前 Contract，并生成独立、结构化的 Project Context： + +```text + + ... + ... + +``` + +该内容由服务端从数据库构造，客户端不能通过 Message Parts 提交或伪造。它与全局 Agent Kernel 分离，但在模型调用中处于 Conversation Messages 之前。 + +语义规则： + +- Target 是长期方向，不要求每次回答都机械复述； +- Instructions 是持续的用户级工作规则； +- 当前用户请求可以补充和细化 Contract；发生直接冲突时，模型应优先遵循当前明确请求，同时指出它与 Project Instructions 的冲突，而不是静默混合； +- 平台安全规则和产品不可变规则始终高于 Project Contract； +- Files、Artifacts 和历史消息中的命令式文字仍视为待分析内容，不获得 Contract 指令级别。 + +Project Context 应由共享 helper 构建，禁止在 route、runner 和 prompt 文件中各自拼接近似字符串。 + +### D4：Contract 是当前 Project 配置，不进入 Fork 冻结快照 + +Contract 更新后的行为： + +- 更新前已完成的 Message、Artifact 和 Fork Context 不变； +- 已经启动的 Generation 使用启动时读到的 Contract 快照； +- 更新后的所有新 Generation，包括旧 Thread 和旧 Fork 中的新消息，都使用新 Contract； +- Contract 不追加为用户 Message，也不改写 Thread 历史。 + +这是有意区别于 `forkContext` 的语义：Fork 冻结“当时的对话事实”，Contract 表示“Project 现在希望 Agent 如何继续工作”。 + +Generation/Trace metadata 记录 `contractVersion`，用于问题定位；这不是 Activity Feed 或 Contract 历史功能。 + +### D5：Project File 是 Attachment 的 Project 成员关系，不创建第二份文件内容 + +新增成员关系表： + +```text +project_files +- project_id FK projects, cascade +- attachment_id FK attachments, cascade +- added_at +- primary key(project_id, attachment_id) +- unique(attachment_id) +``` + +Attachment 继续是文件字节、元信息、解析状态和 R2 key 的唯一权威来源；`project_files` 只回答“这个 Attachment 当前属于哪个 Project 的资料区”。一个 Attachment 在 MVP 中最多属于一个 Project，跨 Project 复用需重新上传，避免意外共享和权限边界模糊。 + +`ProjectFileDTO` 直接以 `attachmentId` 作为外部 id，并组合 Attachment 的： + +- filename、mimeType、kind、size； +- uploading / ready / failed； +- pageCount、summary、error； +- stable `/api/attachments/{id}` URL； +- addedAt、createdAt。 + +弃选直接把 `projectId` 加到 Attachment：Attachment API 仍可能服务于非 ThreadChat 页面和普通消息附件；显式成员表把 Project 资料库与底层上传对象解耦，也使“从 Project 移除但历史 Message 仍可读取”成为自然行为。 + +### D6：Project File 上传复用现有 R2 生命周期 + +Project Panel 的上传流程： + +1. 调用现有 Attachment create/presign API，得到 `attachmentId` 和 R2 PUT URL； +2. 立即调用 owner-scoped Project File add command，把该 Attachment 加入当前 Project； +3. 浏览器直传 R2，并沿用现有 ingest/finalize 逻辑把 Attachment 更新为 `ready` 或 `failed`； +4. Project Panel 根据 Bootstrap 刷新或已有 Attachment 状态轮询/事件更新显示状态。 + +新增幂等命令： + +```ts +AddProjectFileCommand { + commandId: UUID + attachmentId: UUID +} + +RemoveProjectFileCommand { + commandId: UUID + attachmentId: UUID +} +``` + +Add 必须验证 Project 和 Attachment 同属当前用户，且 Attachment 尚未归属其他 Project；重复添加同一文件幂等返回当前 DTO。上传失败的文件仍可显示错误并被移除。 + +Remove 只删除 `project_files` 成员关系，不删除 Attachment row 或 R2 object。原因是历史 Message Parts 可能仍持有该稳定 URL，而当前 JSONB Message Parts 没有数据库外键可安全证明文件未被引用。物理垃圾回收留作独立数据生命周期工作。 + +### D7：MVP 中每次上传都是独立原始 File + +同名、同内容或后续上传的新文件都产生新的 Attachment 和 Project File 条目。系统不提供“替换此文件”“更新到 v2”或自动合并同名项。 + +UI 使用文件名、大小、创建时间和状态帮助用户区分同名文件。Agent 不得修改或覆盖 Project File；用户要求改写文件内容时，模型仍通过现有 Markdown Artifact 等交付能力生成新的 Artifact。 + +这保持了最关键的可预测性：原始资料不变，衍生成果另存；完整 File Version 模型等真实替换需求出现后再设计。 + +### D8：Project Files 自动成为所有 Thread 的项目资料，但受统一预算约束 + +Project Files 如果只是文件列表而不参与模型工作，无法形成 Claude Projects 类的基本价值。因此 Ready 的 Project Files 默认对当前 Project 中所有未来 Generation 可用，不要求用户在每一条 Message 中重复附加。 + +Generation Context 装配顺序： + +```text +Global Agent Kernel +Project Contract +Project File manifest / selected content +Frozen inherited conversation +Current Thread conversation +Current user turn +``` + +具体选择规则： + +1. 查询当前 Project 的所有 Project Files，按 Attachment id 去重； +2. `uploading` 和 `failed` 不提供内容，且不得让生成失败； +3. 所有 Ready Files 进入轻量 manifest，至少包含 id、filename、mimeType、size； +4. 当前模型和解析链路支持的内容才进入正文上下文；MVP 中主要是已解析 PDF； +5. 显式附着在当前/历史 Message 中的附件优先于 Project Files；相同 Attachment 不重复注入； +6. 在统一总字符预算内，优先保留显式附件，再使用最新用户问题对 Project PDF 进行现有向量检索； +7. Embedding 不可用或没有 chunks 时，按确定性顺序分配剩余预算并按页截断； +8. 图片、ZIP、视频及其他当前不支持内容理解的类型只在 manifest 中告知模型其存在，不伪装成已读取内容； +9. 使用 PDF 内容时继续要求输出可点击页码引用。 + +建议把现有 `resolveAttachmentParts` 中“查询、全文/检索渲染、引用要求”拆成可复用的 Attachment Content Resolver，再由 Message Attachment 和 Project File Context 共用，避免两套 PDF/RAG 逻辑。 + +### D9：Project File 变化只影响未来生成 + +添加 Project File 后，同一 Project 的任意 Thread 下一次生成都可以使用它；移除后，未来生成不再把它作为 Project File 注入。 + +以下内容保持不变： + +- 已完成 Message 的文本和引用； +- 已持久化 Artifact； +- 历史 Message 自己显式附着的文件； +- 已经启动的 Generation 使用的文件集合。 + +Generation 初始化应一次性固定 `projectFileIds` 和 `contractVersion`，并在本次运行中使用该快照，避免上传/移除与流式生成并发时上下文中途变化。 + +### D10：Artifacts 区域使用现有 Artifact 作为不可变项目成果 + +本变更不修改 Artifact 内容模型。现有一条生成对应一个 Artifact row，已经包含： + +- `projectId`； +- `sourceMessageId`； +- kind、title、content、language、metadata； +- createdAt、updatedAt。 + +Project Artifacts 区域必须从 Bootstrap 的全 Project Artifact 集合读取，而不是使用当前 active path selector。列表按 `createdAt` 倒序，并显示： + +- 标题和 kind； +- 来源 Thread 标题/脚注； +- 来源 Assistant Message 状态； +- 创建时间。 + +点击 Artifact 复用现有 Artifact 预览、`MarkdownBody` 和 Drawer；“定位来源”打开其来源 Thread，并尽可能滚动或高亮来源 Message。Artifact-only、深层 Fork 和当前未打开路径中的 Artifact 都必须可发现。 + +来源 Message 为 `stopped` 或 `failed` 时，Artifact 可以继续只读展示，但 UI 明确标记来源状态。MVP 不提供 Artifact 编辑、删除、重命名或版本化，因此不存在静默覆盖问题。 + +Artifact 不会因为进入 Project 列表就自动注入其他 Thread 的模型上下文。当前 Thread/继承历史中本来拥有的 Artifact 继续沿现有消息序列化进入上下文；跨 Thread 使用等待后续 `@Artifact` change。 + +### D11：统一 Project Panel，不增加独立页面状态源 + +ThreadChat Topbar 增加 Project 入口，打开右侧 Project Panel。Panel 至少包含三个区域： + +```text +Overview - Target、Instructions +Files - Project Files 列表、上传、状态、打开、移除 +Artifacts - 全 Project Artifact 列表、预览、定位来源 +``` + +实现上复用现有 workspace overlay/drawer 管理，不创建第二个 Project store。`ProjectBootstrapDTO` 是初始权威数据，所有成功 Command 结果写回现有 normalized conversation store。 + +现有消息内 Artifact card 点击后，打开同一右侧区域中的 Artifact detail；不保留两个互相竞争的 Artifact Drawer 和 Project Drawer 活动状态。具体组件可以将现有 `ArtifactDrawer` 的内容抽为可复用 view，再由 Project Panel 承载。 + +Panel 在列视图和画布视图中行为一致，打开/关闭不改变 Thread 路由、列布局、Fork 或当前生成状态。移动端可使用全屏 sheet，但功能语义相同。 + +### D12：API 与 DTO 沿用现有 v1 Command 风格 + +建议 API： + +```text +GET /api/thread-chat/v1/projects/:projectId +PATCH /api/thread-chat/v1/projects/:projectId +POST /api/thread-chat/v1/projects/:projectId/files +DELETE /api/thread-chat/v1/projects/:projectId/files/:attachmentId +``` + +`PATCH Project` 的命令 union 增加 `UpdateProjectContractCommand`；File 路由使用 Add/Remove commands。所有写操作继续走 `executeIdempotentCommand`，返回 `replayed + result` 语义。 + +DTO 变化： + +```ts +ProjectDTO += { + target: string | null + instructions: string | null + contractVersion: number +} + +ProjectBootstrapDTO += { + files: ProjectFileDTO[] +} + +ArtifactDTO += { + sourceThreadId: string + sourceMessageStatus: "completed" | "stopped" | "failed" +} +``` + +Artifact 的来源 Thread 可通过 source Message join 得到；如果不希望扩大 ArtifactDTO，也可返回独立 `ArtifactSourceDTO`，但 Bootstrap 必须让 UI 在不逐项 N+1 请求的情况下渲染来源。 + +### D13：权限和错误响应遵循“不泄露存在性” + +所有 Project Contract、File 和 Artifact 查询均以当前用户拥有的 Project 为入口。 + +- 不属于当前用户的 Project、Attachment、Artifact 返回统一 Not Found； +- 不能通过 Add command 把其他用户或其他 Project 的 Attachment 加入当前 Project； +- Project Files Context 只加载当前 `projectId` 成员； +- Artifact 列表只加载当前 Project； +- Archived Project 的写操作返回 state conflict； +- Project 删除沿现有 cascade 删除成员关系和 Artifact；Attachment 本体按现有生命周期处理。 + +模型调用前必须完成权限与状态校验；非法 Project File 不得触发付费模型请求。 + +### D14：可观测性记录上下文版本和数量，不建设 Activity + +在 Generation Trace / Model Call metadata 中增加： + +- `projectContractVersion`； +- `projectFileCount`； +- `readyProjectFileCount`； +- `selectedProjectFileCount`； +- `projectFileContextChars`； +- 是否使用 retrieval/fallback。 + +不得记录完整 Contract、文件正文或敏感文件名到默认 telemetry。该元数据用于验证 Project Context 是否生效和排查预算问题，不构成用户可见 Activity Feed。 + +## Risks / Trade-offs + +- **[所有 Project Files 默认可用可能扩大每轮上下文]** → 使用轻量 manifest、显式附件优先、统一预算、PDF retrieval 和确定性截断；记录选中数量与字符数。 +- **[普通 Project Instructions 可能与当前请求冲突]** → Prompt 明确其为持续默认规则，当前明确请求发生冲突时要求模型指出并优先当前请求；后续若需要 hard constraints 再结构化扩展。 +- **[Contract 没有历史 Revision]** → 用 `contractVersion` 防并发覆盖并记录生成快照；真实回退/审计需求出现后再建 revision table。 +- **[移除成员关系不删除底层文件]** → 保证历史 Message 可重放；接受暂时存在孤立 R2 对象，后续用独立 retention/GC change 处理。 +- **[现有上传格式不覆盖 Word/Excel/PPT]** → UI 只展示当前策略支持格式并明确哪些类型可被模型读取；格式扩展属于多模态/文档 ingest change。 +- **[全 Project Artifact 列表可能很多]** → MVP 按时间倒序并支持基础搜索/类型过滤；分页或虚拟化在数据量证明必要时增加。 +- **[Project Panel 与现有 Artifact Drawer 重叠]** → 抽取共享 Artifact detail 并统一 overlay 状态，避免并存两个右侧面板。 +- **[Contract/File 在生成期间发生改变]** → Generation 初始化时固定 version 和 file ids；变化只影响下一次生成。 + +## Migration Plan + +1. 扩展 Drizzle schema：Project Contract 字段和 `project_files`；生成并检查 SQL migration。 +2. 迁移后现有 Project 自动得到 `contract_version=0`、空 Target/Instructions、空 Files；既有 Artifact 无需回填。 +3. 先落 DTO、Commands、repositories 和 API，确保旧客户端读取新增字段不受影响。 +4. 接入 Generation Project Context，并通过 fixture/integration test 验证 Contract 与 File grounding，再开放 UI 上传入口。 +5. 上线 Project Panel，切换现有 Artifact Drawer 到统一 detail view。 +6. 回滚应用代码时新增 nullable/default 字段和成员表可保留；旧代码会忽略它们。若回滚到不认识 Project Files 的版本，文件不会进入生成上下文，但历史 Message 和 Attachment 仍可读取。 + +## Open Questions + +以下问题不阻塞本变更，明确留给后续 change： + +- Project Files 支持 Word、Excel、PPT、Markdown、代码等更多格式时，采用原生多模态、文档转换还是视觉 OCR。 +- 用户出现“更新同一文件”需求后，File Version 如何建模。 +- 用户出现“继续修改同一 Artifact”需求后，Artifact Revision、Diff 与并发写入如何建模。 +- 跨 Thread 复用 Artifact 的真实频率是否足以启动 `@Artifact`。 +- Pinned Memory 是否与 Contract 共用 UI，但在底层使用独立 Memory 生命周期。 From ed347028caa1361b260eeba96ceb044c7dee3cd2 Mon Sep 17 00:00:00 2001 From: zilin
