## 一、 背景与业务目标 (Background & Objectives)
|
||||
|
||||
### 1.1 业务背景
|
||||
|
||||
在医疗器械 CDMO 全流程协同体系中，一个项目从**策划立项 → 研发设计 → 验证测试 → 注册申报 → 结项归档**，周期通常以月甚至年计。项目工作台的对话流是贯穿全程的决策留痕载体：立项沟通、需求摸底、任务执行、文档审核、交付物上传下载全部沉淀在同一会话中，单会话消息量将随项目推进增长到数千乃至上万条、跨越数十至数百个自然日。
|
||||
|
||||
### 1.2 现状痛点（代码实证根因）
|
||||
|
||||
| # | 根因 | 代码位置 | 用户可感知后果 |
|
||||
| :--- | :--- | :--- | :--- |
|
||||
| 1 | 前端将**全部会话消息**整体存入 localStorage，启动时全量 `JSON.parse`，切换会话时全量 `filter` | `web/src/data/storage.ts` `loadMessages()`；`web/src/App.tsx` `messages.filter(...)` | 打开工作台即全量加载，历史越长首屏越慢；localStorage 5MB 上限迟早溢出 |
|
||||
| 2 | 消息流**全量渲染 DOM（无虚拟化）**，且每次消息变化执行 `scrollIntoView({ behavior: 'smooth' })` 平滑滚动 | `web/src/components/chat/MessageStream.tsx` | 打开旧会话时肉眼可见"从头滚到底"的长滚动过程，体验极差 |
|
||||
| 3 | 历史查询接口按 `created_at ASC + LIMIT/OFFSET` 正序分页 | `internal/ctxmgr/chat_history.go` `GetChatHistory`；`GET /api/v1/chat/messages` | 前端想看到"最新对话"必须从最旧一页页翻到底 |
|
||||
| 4 | 缺乏面向用户的**导航设施**：无按日分片、无分类筛选、无锚点、无搜索、无引用互链、无日期跳转、无每日摘要 | — | 用户"记得当时聊过 X，但找不到在哪"，只能肉眼滚动翻找 |
|
||||
|
||||
### 1.3 设计目标
|
||||
|
||||
1. **首屏直达最新**：打开会话只加载最近 7 天（可配置）消息窗口，且**无滚动动画、瞬时落位**在最新消息处；
|
||||
2. **按日归档分片**：对话历史以自然日为归档与加载单元，向上滚动按日增量加载，滚动位置不跳动；
|
||||
3. **多级导航**：分类筛选（闲聊/咨询/任务/审核/文件/里程碑/系统）、全文/模糊/语义三模搜索、日历日期跳转、每日智能摘要跳转，四类入口统一收敛到**锚点定位协议**；
|
||||
4. **消息引用互链**：用户与智能体双方均可引用历史消息，点击引用即锚点定位；
|
||||
5. **每日智能摘要**：智能体按日生成工作摘要（要点、产出、决策、未决），用户凭摘要跳转到目标日期首条消息；
|
||||
6. **性能可量化**：以明确的 P95 预算约束实现与验收（见第十章）。
|
||||
|
||||
### 1.4 非目标 (Out of Scope)
|
||||
|
||||
- 不改变既有 `chat_summaries`（会话级滚动摘要）的 Prompt 压缩职责，本设计的每日摘要是**面向用户导航的展示物**，二者分工协同（见 4.3）；
|
||||
- 不在本期引入前端路由库与虚拟滚动依赖（P3 再评估，见十一章 P3）；
|
||||
- 不做消息编辑与撤销（软删除策略仅作引用兜底预案，见 4.5）。
|
||||

||||

## 二、 需求梳理与总体思路 (Requirements & Overall Approach)
|
||||
|
||||
### 2.1 原始需求逐条深化
|
||||
|
||||
| # | 原始诉求 | 深化后的设计要点 |
|
||||
| :--- | :--- | :--- |
|
||||
| R1 | 按日归档；进入只加载最近 7 天；直接在最新位置，无滚动过程 | DB 层 `day_key` 分片列 + 专用窗口查询；前端**倒序请求、正序渲染**、`useLayoutEffect` 中一次性 `scrollTop` 落底（`behavior:'auto'`，全程禁用 smooth）；向上触顶按日 prepend 且滚动位置补偿 |
|
||||
| R2 | 分类（闲聊/咨询/任务/审核/上传导出下载）+ 锚点快速定位 | 消息落库时打 `category` 标签（对齐既有 `intent`/`branch`/`metadata`/`project_activities.activity_type` 词表）；存量数据 SQL 回填；锚点 = `chat_messages.id`（天然全局唯一）；分类侧栏 + 分类筛选条 |
|
||||
| R3 | 关键词/模糊/语义搜索 → 锚点定位 | 三模检索：`ILIKE`/`pg_trgm`（关键词+模糊）+ `pgvector`（语义，复用 `context_memory_chunks` 与既有 Embedder 降级体系）；结果按日分组带高亮摘录片段 |
|
||||
| R4 | 对话内引用，点击引用定位锚点 | 双向引用：用户发送时可引用（输入区引用选择器）；智能体回复 metadata 自动携带依据引用；渲染 `QuoteCard`，点击走锚点定位协议 |
|
||||
| R5 | 按日期跳转到当日第一条 | 日历组件（有消息的日期打点）→ 拉取当日窗口 → 定位当日首条消息锚点 |
|
||||
| R6 | 按日智能体摘要 → 跳转目标日期首条 | 新表 `chat_daily_digests`；LLM（`internal/agent` Backend）+ 规则降级双轨；定时 + 懒生成 + 当日节流增量三种时机；摘要时间轴侧栏 |
|
||||
|
||||
### 2.2 体系关系：锚点是公共底座
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────┐
|
||||
│ 四类导航入口（收敛层） │
|
||||
│ 分类筛选 三模搜索 日期跳转 每日摘要 │
|
||||

|
||||

||||

||||

│ 按日消息窗口 (7 天起步, 触顶 │
|
||||
│ 向上按日加载, 滚动位置补偿) │
|
||||
└──────────────────────────────┘
|
||||
```
|
||||
|
||||
**核心抽象**：R2/R3/R5/R6 四个入口与 R4 引用点击，全部收敛到唯一的 `navigateToAnchor(messageId)` 前端服务。"目标消息不在当前已加载窗口"的拉取-插入-定位逻辑**只实现一份**，任何新导航入口零成本复用。
|
||||
|
||||
### 2.3 补充设计建议（编制者增补，已纳入本设计）
|
||||
|
||||
| # | 建议 | 动机 |
|
||||
| :--- | :--- | :--- |
|
||||
| A1 | **首屏落位禁用一切滚动动画** | 现状 `smooth` 滚动是"滚动过程"体验差的直接原因；恢复/落位一律 `auto`，仅新消息到达且用户已在底部时才平滑跟随 |
|
||||
| A2 | **消息 ID 稳定性协议** | 现状前端消息 id 为 `'sys-rej-' + Date.now()` 之类的临时字符串，无法充当锚点；规定：锚点一律使用**服务端数字 id**，SSE 流式期间用临时 id，`done` 事件回传真实 id 后前端原地替换（衔接既有 `sourceUserMessageId` 机制） |
|
||||
| A3 | **里程碑节点导航** | 复用既有 `project_activities.is_milestone`（阶段推进、审批通过、报价确认等不衰减事件），在时间轴侧栏提供"关键节点"入口——长周期项目里用户最想找的往往就是"当时拍板的那个节点"，比分类筛选更精准 |
|
||||
| A4 | **localStorage 窗口化迁移** | 前端不再全量持久化消息；仅缓存当前会话窗口（LRU 3 会话）与输入草稿；历史 SSOT 归数据库（三套环境已有独立 DB，天然支持） |
|
||||
| A5 | **每日摘要与 `chat_summaries` 分工协同** | `chat_summaries`：会话级、机器上下文压缩（喂 Prompt）；`chat_daily_digests`：按日、面向用户导航展示 + 可选注入跨日记忆；摘要向量化沉淀进 `context_memory_chunks`（新 domain `daily_digest`），打通既有语义记忆体系 |
|
||||
| A6 | **聊天记录按日/按分类导出** | 复用前端已有 `docx` / `xlsx` 依赖，导出带锚点编号的日记录/分类记录，满足医疗器械决策追溯与审计合规诉求 |
|
||||
| A7 | **搜索 RBAC 权限边界** | 与三级交付物隐私设计一致：私聊内容仅本人可搜；项目共享会话按角色过滤，搜索在服务端过滤而非前端过滤 |
|
||||
| A8 | **性能预算量化验收** | 所有体验诉求转成 P95 指标（第十章），压测种子数据（90 天 / 12000 条）进入测试方案 |
|

```
|
||||
|
||||
### 数据流关键节点
|
||||
|
||||
1. **写入打标**：`RecordUserMessage` 落库时由应用层计算 `day_key`（统一 `CHAT_TZ`，默认 `Asia/Shanghai`）并依据 `intent`/`branch`/`metadata` 推导 `category`；
|
||||
2. **首屏窗口**：前端打开会话 → `GET /chat/messages/window?days=7`（服务端按 `day_key DESC` 取日集合、每日内取最新 `MAX_MSG_PER_DAY` 条后正序返回）→ 前端渲染后 `scrollTop` 一次性落底；
|
||||
3. **触顶加载**：滚动接近顶部 → `window?before_day={oldest}` → prepend 前按 `scrollHeight` 差值补偿，视口不跳动；
|
||||
4. **锚点定位**：任意入口触发 `navigateToAnchor(id)` → 已在窗口内直接定位；否则 `GET /chat/messages/day?date=&anchor_id=&context=N` 拉目标日及上下文 → 插入窗口 → `scrollIntoView({block:'center', behavior:'auto'})` → 高亮脉冲 1.8s；
|
||||
5. **搜索**：`GET /chat/search` 三模打分 → 按日分组结果（含高亮摘录）→ 点击走 4；
|
||||
6. **每日摘要**：Scheduler 每日 00:10 (CHAT_TZ) 对前一日生成；或懒生成（首次请求未命中时异步触发，返回占位状态）；摘要向量化沉淀 `context_memory_chunks(domain='daily_digest')` 供跨会话语义召回；
|
||||
7. **里程碑**：时间轴侧栏直接读 `project_activities` 中 `is_milestone = true` 事件，`detail.message_id` 关联消息，点击即锚点定位。
|
||||

|
||||
|
||||
## 四、 数据库模式设计 (Database Schema)
|
||||
|
||||
### 4.1 `chat_messages` 增列与索引（迁移脚本新增于 `deploy/postgres/migrations/`）
|
||||
|
||||
```sql
|
||||
-- 按日归档分片键：由应用层写入（避免时区歧义与生成列 IMMUTABLE 争议），统一 CHAT_TZ
|
||||
ALTER TABLE chat_messages
|
||||
ADD COLUMN IF NOT EXISTS day_key DATE,
|
||||
ADD COLUMN IF NOT EXISTS category TEXT NOT NULL DEFAULT 'uncategorized';
|
||||
|
||||
-- 窗口/日查询主索引：(会话, 日, 顺序)
|
||||
CREATE INDEX IF NOT EXISTS idx_chat_messages_sid_day_id
|
||||
ON chat_messages(session_id, day_key DESC, id DESC);
|
||||
-- 分类筛选索引
|
||||
CREATE INDEX IF NOT EXISTS idx_chat_messages_sid_category
|
||||
ON chat_messages(session_id, category, id DESC);
|
||||
|
||||
-- 存量回填（幂等，可重复执行）
|
||||
UPDATE chat_messages
|
||||
SET day_key = (created_at AT TIME ZONE 'Asia/Shanghai')::date
|
||||
WHERE day_key IS NULL;
|
||||
|
||||
UPDATE chat_messages SET category = CASE
|
||||
WHEN intent IN ('CASUAL_CHAT') THEN 'casual'
|
||||
WHEN intent IN ('QUERY_PROGRESS','QUERY_REGULATIONS','SUPPLEMENT_INFO','AMBIGUOUS_FALLBACK') THEN 'consult'
|
||||
WHEN intent IN ('TRIGGER_TASK','ADVANCE_STAGE') OR metadata ? 'task_request' THEN 'task'
|
||||
WHEN intent LIKE 'DOCGOV%' OR metadata ? 'interactive_card' THEN 'review'
|
||||
WHEN metadata ? 'attachments' OR metadata ? 'file_op' THEN 'file'
|
||||
WHEN role = 'system' THEN 'system'
|
||||
ELSE 'uncategorized' END
|
||||
WHERE category = 'uncategorized' OR category = '';
|
||||
```
|
||||
|
||||
> `day_key` 采用**应用层写入**而非 DB 生成列：`RecordUserMessage` / SSE 会话服务写入时统一计算，与项目既有"显式列 INSERT"习惯一致，规避 `AT TIME ZONE` 在生成列中的可移植性争议；回填脚本仅一次性使用。
|
||||
|
||||
### 4.2 分类词表（`category`，与既有体系统一）
|
||||
|
||||
| category | 展示名 | 判定来源（写入时按优先级短路） |
|
||||
| :--- | :--- | :--- |
|
||||
| `milestone` | 里程碑 | `metadata.milestone = true`（由 `RecordActivity(is_milestone=true)` 联动写入） |
|
||||
| `file` | 文件操作 | `metadata.attachments`、`metadata.file_op ∈ {upload, export, download}`（对齐 `project_activities.activity_type`） |
|
||||
| `review` | 审核治理 | DocGov 意图、`metadata.interactive_card`、驳回/批准系统消息 |
|
||||
| `task` | 任务执行 | `intent ∈ {TRIGGER_TASK, ADVANCE_STAGE}` 或 `metadata.task_request` 存在 |
|
||||
| `consult` | 咨询 | `intent ∈ {QUERY_PROGRESS, QUERY_REGULATIONS, SUPPLEMENT_INFO, AMBIGUOUS_FALLBACK}` |
|
||||
| `casual` | 闲聊 | `intent = CASUAL_CHAT` |
|
||||
| `system` | 系统通知 | `role = system` |
|
||||
| `uncategorized` | 未分类 | 兜底（前端归入"全部"） |
|
||||
|
||||
### 4.3 新表 `chat_daily_digests`（按日智能摘要）
|
||||
|
||||
```sql
|
||||
CREATE TABLE IF NOT EXISTS chat_daily_digests (
|
||||
id BIGSERIAL PRIMARY KEY,
|
||||
session_id TEXT NOT NULL REFERENCES chat_sessions(session_id) ON DELETE CASCADE,
|
||||
project_id BIGINT REFERENCES projects(id) ON DELETE SET NULL,
|
||||
day_key DATE NOT NULL,
|
||||
headline TEXT NOT NULL DEFAULT '', -- 一句话日总结 (≤40 字)
|
||||
key_points JSONB NOT NULL DEFAULT '[]'::jsonb, -- 工作要点 (string[])
|
||||
deliverables JSONB NOT NULL DEFAULT '[]'::jsonb, -- 当日产出 [{doc_id,title,state}]
|
||||
decisions JSONB NOT NULL DEFAULT '[]'::jsonb, -- 当日拍板决策 (string[])
|
||||
open_questions JSONB NOT NULL DEFAULT '[]'::jsonb, -- 未决事项 (string[])
|
||||
stage_progress TEXT NOT NULL DEFAULT '', -- 当日阶段推进 (如 V0.1→V0.5)
|
||||
first_message_id BIGINT, -- 当日首条消息 (跳转锚点)
|
||||
last_message_id BIGINT,
|
||||
message_count INT NOT NULL DEFAULT 0,
|
||||
status TEXT NOT NULL DEFAULT 'pending', -- pending|generating|ready|fallback|failed
|
||||
source TEXT NOT NULL DEFAULT '', -- llm | rule (对齐 reply_source 习惯)
|
||||
model TEXT NOT NULL DEFAULT '',
|
||||
token_usage INT NOT NULL DEFAULT 0,
|
||||
digest_version INT NOT NULL DEFAULT 1, -- 当日增量再生成时 +1
|
||||
generated_at TIMESTAMPTZ,
|
||||
updated_at TIMESTAMPTZ NOT NULL DEFAULT now(),
|
||||
UNIQUE (session_id, day_key)
|
||||
);
|
||||
CREATE INDEX IF NOT EXISTS idx_digests_sid_day ON chat_daily_digests(session_id, day_key DESC);
|
||||
```
|
||||
|
||||
**与既有 `chat_summaries` 的分工**：`chat_summaries` 保持"会话级滚动压缩、喂 Prompt"职责不变；`chat_daily_digests` 是按日、面向用户导航的结构化展示物。`DailyDigestGenerator` 生成成功后可将 `headline + key_points` 注入 `RestoreSessionContext` 跨日记忆段作为补充（配置 `DIGEST_INTO_PROMPT`，默认关闭）。
|
||||
|
||||
### 4.4 搜索基础设施
|
||||
|
||||
```sql
|
||||
CREATE EXTENSION IF NOT EXISTS pg_trgm;
|
||||
-- 关键词/模糊检索共用
|
||||
CREATE INDEX IF NOT EXISTS idx_chat_messages_content_trgm
|
||||
ON chat_messages USING GIN (content gin_trgm_ops);
|
||||
```
|
||||
|
||||
- **语义检索**复用既有 `context_memory_chunks`（1024 维 + HNSW + `chunk_hash` 幂等防重），新增两个 domain 取值：
|
||||
- `chat_message`：`reference_id = "msg:{chat_messages.id}"`，选择性向量化——仅对 `role = user` 消息与 `status = completed` 的助手终稿消息异步入库（控制 token 与存储成本）；
|
||||
- `daily_digest`：`reference_id = "digest:{session_id}:{day_key}"`，每日摘要生成后同步沉淀。
|
||||
- **中文全文**：`pg_trgm` 按字符 trigram 处理即可覆盖"关键词包含 + 模糊相似"两档；`zhparser`/`pg_jieba` 分词列为后续可选增强，本期不引入。
|
||||
|
||||
### 4.5 消息软删除预案（引用兜底）
|
||||
|
||||
```sql
|
||||
ALTER TABLE chat_messages
|
||||
ADD COLUMN IF NOT EXISTS deleted_at TIMESTAMPTZ; -- 软删除标记, 默认 NULL
|
||||
```
|
||||
|
||||
窗口/日/搜索查询一律过滤 `deleted_at IS NULL`；被引用消息软删除后，`QuoteCard` 降级为"仅展示快照摘录 + 已删除"样式，不再尝试锚点定位。
|
||||
|

|
||||
|
||||
## 五、 核心组件与接口设计 (Core Components & Interfaces)
|
||||
|
||||
### 5.1 Go 后端：`internal/ctxmgr/chat_window.go`（新增）
|
||||
|
||||
```go
|
||||
// ChatDayBucket 按日消息分片桶
|
||||
type ChatDayBucket struct {
|
||||
DayKey string `json:"day_key"` // "2026-09-10"
|
||||
Count int `json:"count"` // 当日消息总数(未截断)
|
||||
LoadedCount int `json:"loaded_count"` // 本次实际返回条数
|
||||
Truncated bool `json:"truncated"` // 单日超 MAX_MSG_PER_DAY 截断标记
|
||||
FirstMessageID int64 `json:"first_message_id"`
|
||||
LastMessageID int64 `json:"last_message_id"`
|
||||
Messages []ChatMessageRecord `json:"messages"` // 正序
|
||||
}
|
||||
|
||||
// ChatWindowQuery 按日窗口查询参数
|
||||
type ChatWindowQuery struct {
|
||||
SessionID string
|
||||
Days int // 默认 7, 上限 31
|
||||
BeforeDay string // 触顶加载: 早于此日的下一段 (YYYY-MM-DD), 空则取最新
|
||||
}
|
||||
|
||||
// GetChatWindow 获取最近 N 日消息窗口(倒序取日 → 每日取最新 MAX_MSG_PER_DAY 条 → 正序返回)
|
||||
func (m *ContextManager) GetChatWindow(ctx context.Context, q ChatWindowQuery) (*ChatWindowResult, error)
|
||||
|
||||
// GetChatDayMessages 获取指定日全量消息(分页游标), 支持 anchor_id 上下文补齐
|
||||
func (m *ContextManager) GetChatDayMessages(ctx context.Context, sessionID, dayKey string, anchorID int64, beforeID, afterID int64, limit int) (*ChatDayMessagesResult, error)
|
||||
|
||||
// ListChatDates 列出会话有消息的日期及计数(日历打点 + 摘要联动)
|
||||
func (m *ContextManager) ListChatDates(ctx context.Context, sessionID string) ([]ChatDateStat, error)
|
||||
|
||||
// GetChatCategoryStats 会话内分类统计 + 各类首末锚点样例
|
||||
func (m *ContextManager) GetChatCategoryStats(ctx context.Context, sessionID string) ([]ChatCategoryStat, error)
|
||||
|
||||
// DeriveMessageCategory 写入时打标(4.2 词表的 Go 实现, 供 RecordUserMessage 调用)
|
||||
func DeriveMessageCategory(role, intent, branch string, meta map[string]any) string
|
||||
```
|
||||
|
||||
**实现要点**：
|
||||
- `GetChatWindow` 两段查询：`SELECT DISTINCT day_key ... WHERE session_id=$1 AND day_key < $2 ORDER BY day_key DESC LIMIT $3` → 逐日 `ORDER BY id DESC LIMIT MAX_MSG_PER_DAY(300)` 后内存反转，天然复用 `idx_chat_messages_sid_day_id`；
|
||||
- 单日截断不丢锚点能力：`truncated=true` 时前端在 `DayDivider` 显示"本日共 N 条，已加载最新 300 条"，点击后经 `GetChatDayMessages` 游标翻全量；
|
||||
- 内存降级模式（`pool == nil`）沿用既有双轨习惯：`m.messages` 全量切片上做等价窗口切片，保证单测零依赖。
|
||||
|
||||
### 5.2 Go 后端：`internal/ctxmgr/chat_search.go`（新增 ChatSearchService）
|
||||
|
||||
```go
|
||||
// ChatSearchMode 检索模式
|
||||
type ChatSearchMode string // keyword | fuzzy | semantic | hybrid
|
||||
|
||||
// ChatSearchQuery 搜索入参
|
||||
type ChatSearchQuery struct {
|
||||
SessionID string // 会话内搜索(必填)
|
||||
ProjectID int64 // 可选: 项目级跨会话搜索
|
||||
UserID int64 // 调用者(用于 RBAC 私聊过滤)
|
||||
Query string
|
||||
Mode ChatSearchMode // 默认 hybrid
|
||||
Category string // 可选分类过滤
|
||||
DateFrom, DateTo string // 可选日期范围
|
||||
Limit int // 默认 50, 上限 200
|
||||
}
|
||||
|
||||
// ChatSearchHit 搜索命中
|
||||
type ChatSearchHit struct {
|
||||
MessageID int64 `json:"message_id"` // 锚点
|
||||
SessionID string `json:"session_id"`
|
||||
DayKey string `json:"day_key"`
|
||||
Role string `json:"role"`
|
||||
Category string `json:"category"`
|
||||
Excerpt string `json:"excerpt"` // 命中词 ±40 字上下文, 前端高亮
|
||||
Score float64 `json:"score"`
|
||||
MatchedBy string `json:"matched_by"` // keyword|fuzzy|semantic
|
||||
}
|
||||
|
||||
// SearchChatMessages 统一搜索入口: 服务端 RBAC 过滤 + 三模打分 + 归一化融合
|
||||
func (m *ContextManager) SearchChatMessages(ctx context.Context, q ChatSearchQuery) ([]ChatSearchHit, error)
|
||||
```
|
||||
|
||||
**实现要点**：
|
||||
- **keyword**：`content ILIKE '%q%'`（GIN trgm 索引加速），得分按命中段数归一；
|
||||
- **fuzzy**：`similarity(content, q) > 0.30 ORDER BY similarity DESC`（`pg_trgm`）；
|
||||
- **semantic**：`q` 经 `VectorEmbedder` 向量化（生产 bge-m3 / 离线 `DeterministicEmbedder` 降级，复用既有体系）→ `context_memory_chunks WHERE domain='chat_message'` 余弦 TopK，再 JOIN 回 `chat_messages` 取摘录；
|
||||
- **hybrid**：三路结果按 `min-max` 归一后加权（keyword 0.4 / fuzzy 0.2 / semantic 0.4）去重合并；
|
||||
- **RBAC**：私聊会话（`project_id IS NULL` 或私有标记）仅 `user_id` 匹配可命中；项目会话按调用者角色过滤（与三级交付物隐私设计对齐）。
|
||||
|
||||
### 5.3 Go 后端：`internal/ctxmgr/chat_digest.go`（新增 DailyDigestScheduler / Generator）
|
||||
|
||||
```go
|
||||
// DailyDigestInput 单日摘要生成输入
|
||||
type DailyDigestInput struct {
|
||||
SessionID string
|
||||
DayKey string
|
||||
Messages []ChatMessageRecord // 当日全部消息(服务端取)
|
||||
}
|
||||
|
||||
// DailyDigest 摘要产出(即 chat_daily_digests 行的 Go 映射)
|
||||
type DailyDigest struct {
|
||||
SessionID string `json:"session_id"`
|
||||
DayKey string `json:"day_key"`
|
||||
Headline string `json:"headline"`
|
||||
KeyPoints []string `json:"key_points"`
|
||||
Deliverables []DigestDeliverable `json:"deliverables"`
|
||||
Decisions []string `json:"decisions"`
|
||||
OpenQuestions []string `json:"open_questions"`
|
||||
StageProgress string `json:"stage_progress"`
|
||||
FirstMessageID int64 `json:"first_message_id"` // 跳转锚点
|
||||
LastMessageID int64 `json:"last_message_id"`
|
||||
MessageCount int `json:"message_count"`
|
||||
Status string `json:"status"`
|
||||
Source string `json:"source"` // llm | rule
|
||||
DigestVersion int `json:"digest_version"`
|
||||
}
|
||||
|
||||
// GenerateDailyDigest 单日摘要生成: LLM 优先, 规则降级
|
||||
// LLM: agent.Backend (pi-agent + MiniMax), 输出强制 JSON Schema;
|
||||
// 当日消息 > 80 条时 map-reduce: 先按 20 条分段预摘要, 再汇总
|
||||
// 规则降级: 复用 summarizer.go 的确定性抽取思路 (要点=用户消息首句, 决策=metadata.milestone, 产出=file_op)
|
||||
func (m *ContextManager) GenerateDailyDigest(ctx context.Context, sessionID, dayKey string) (*DailyDigest, error)
|
||||
|
||||
// ListDailyDigests 摘要列表查询(时间轴侧栏数据源), status != ready 时可触发懒生成
|
||||
func (m *ContextManager) ListDailyDigests(ctx context.Context, sessionID string, from, to string) ([]DailyDigest, error)
|
||||
|
||||
// StartDailyDigestScheduler 后台调度: 每日 00:10 (CHAT_TZ) 扫描活跃会话生成前一日摘要;
|
||||
// 当日增量: 每 25 条新消息或 30 分钟节流更新一次 status=ready 的当日摘要(digest_version+1)
|
||||
// 参照 internal/bizdev/service.go 心跳 goroutine + stop channel 生命周期模式
|
||||
func (s *Server) StartDailyDigestScheduler(ctx context.Context)
|
||||
```
|
||||
|
||||
**生成时机矩阵**：
|
||||
|
||||
| 时机 | 触发方 | 策略 |
|
||||
| :--- | :--- | :--- |
|
||||
| 定时 | Scheduler 每日 00:10 (CHAT_TZ) | 对所有"前一日有消息"的会话批量生成（并发 worker 2，队列防重） |
|
||||
| 懒生成 | `GET /chat/digests` 未命中 | 异步触发（`status=pending→generating`），接口立即返回占位；前端 60s 轮询或 SSE `digest_ready` 事件通知 |
|
||||
| 当日增量 | Scheduler 节流（25 条/30 分钟） | 重新生成当日摘要，`digest_version+1`，避免频繁全量重算 |
|
||||
| 手动 | `POST /chat/digests/generate` | 用户/管理员强制重生成指定日 |
|
||||
|
||||
**幂等与降级**：`UNIQUE(session_id, day_key)` + `status=generating` 抢占防并发重复；LLM 失败自动落 `source=rule, status=fallback`，连续失败 3 次标记 `failed` 并告警；摘要成功后异步向量化沉淀（`domain='daily_digest'`）。
|
||||
|
||||
---
|
||||
|
||||
## 六、 RESTful API 契约设计 (API Contracts)
|
||||
|
||||
> 全部挂载于 `internal/server/server.go` 既有 `mux.HandleFunc` 模式，前缀 `/api/v1`。既有 `GET /api/v1/chat/messages`（CLI/黑盒脚本在用）**原样保留兼容**，新能力一律新端点。
|
||||
|
||||
### 6.1 按日窗口查询（首屏 / 触顶加载）
|
||||
|
||||
- **路径**：`GET /api/v1/chat/messages/window`
|
||||
- **查询参数**：`session_id`(必), `days`(默认 7, 上限 31), `before_day`(可选, YYYY-MM-DD)
|
||||
- **响应**：
|
||||
```json
|
||||
{
|
||||
"session_id": "sess_1788844000",
|
||||
"days": [
|
||||
{
|
||||
"day_key": "2026-09-10", "count": 38, "loaded_count": 38, "truncated": false,
|
||||
"first_message_id": 1024, "last_message_id": 1089,
|
||||
"messages": [ { "id": 1024, "role": "user", "content": "...", "intent": "SUPPLEMENT_INFO",
|
||||
"branch": "EXPECTATION_HIT", "category": "consult",
|
||||
"metadata": {}, "created_at": "2026-09-10T09:12:00+08:00" } ]
|
||||
}
|
||||
],
|
||||
"has_more_before": true,
|
||||
"oldest_loaded_day": "2026-09-03"
|
||||
}
|
||||
```
|
||||
|
||||
### 6.2 指定日消息 + 锚点上下文（日期跳转 / 锚点补齐 / 单日翻全量）
|
||||
|
||||
- **路径**：`GET /api/v1/chat/messages/day`
|
||||
- **查询参数**：`session_id`(必), `date`(必, YYYY-MM-DD), `anchor_id`(可选), `before_id`/`after_id`(可选游标), `limit`(默认 100)
|
||||
- **语义**：无 `anchor_id` 时返回当日**第一条**起正序 `limit` 条（日期跳转定位当日首条）；有 `anchor_id` 时返回锚点**前后各 `limit/2` 条**上下文。
|
||||
|
||||
### 6.3 会话日期列表（日历打点）
|
||||
|
||||
- **路径**：`GET /api/v1/chat/dates?session_id=`
|
||||
- **响应**：`[ { "day_key": "2026-09-10", "count": 38, "categories": {"task": 12, "review": 5}, "digest_status": "ready" } ]`
|
||||
|
||||
### 6.4 分类统计（分类筛选条）
|
||||
|
||||
- **路径**：`GET /api/v1/chat/categories?session_id=`
|
||||
- **响应**：`[ { "category": "task", "label": "任务执行", "count": 512, "first_message_id": 88, "last_message_id": 1089 } ]`
|
||||
|
||||
### 6.5 消息搜索（三模）
|
||||
|
||||
- **路径**：`GET /api/v1/chat/search`
|
||||
- **查询参数**：`session_id`(必), `q`(必), `mode`(keyword|fuzzy|semantic|hybrid, 默认 hybrid), `category`, `date_from`, `date_to`, `limit`(默认 50, 上限 200), `user_id`(调用者, RBAC)
|
||||
- **响应**：`[ { "message_id": 1030, "day_key": "2026-09-09", "role": "assistant", "category": "task", "excerpt": "...预算<b>200万</b>已确认...", "score": 0.91, "matched_by": "keyword" } ]`（`<b>` 由前端按关键词渲染高亮，服务端只回纯文本摘录 + 命中区间）
|
||||
|
||||
### 6.6 每日摘要列表 / 手动生成
|
||||
|
||||
- **路径**：`GET /api/v1/chat/digests?session_id=&from=&to=`
|
||||
- **响应**：`[ { "day_key": "2026-09-09", "headline": "完成注册路径初筛与报价基准确认", "key_points": ["..."], "deliverables": [{"doc_id":"...","title":"注册路径可行性评估报告","state":"approved"}], "decisions": ["确认国内 NMPA + 欧盟 CE 双路径"], "open_questions": ["型检所排期未定"], "stage_progress": "V0.1→V0.5", "first_message_id": 940, "message_count": 52, "status": "ready", "source": "llm", "digest_version": 2 } ]`
|
||||
- 未命中且 `date < 今天` 时：异步触发懒生成，响应包含 `{"status": "generating"}` 占位行 + `202` 语义由字段表达（HTTP 仍 200，前端轮询）。
|
||||
- **路径**：`POST /api/v1/chat/digests/generate`
|
||||
- **请求**：`{ "session_id": "...", "day_key": "2026-09-09" }` → **响应**：`{ "queued": true }`
|
||||
|
||||
### 6.7 既有端点扩展（引用与打标透传）
|
||||
|
||||
- `POST /api/v1/chat/stream`（SSE）请求体新增可选字段：
|
||||
```json
|
||||
{ "session_id": "...", "message": "...", "user_id": 1, "role": "author",
|
||||
"quote": { "message_id": 1030, "excerpt": "预算200万已确认", "author_name": "张工", "day_key": "2026-09-09" } }
|
||||
```
|
||||
服务端将 `quote` 存入该用户消息 `metadata.quote`；助手回复的 `metadata.quotes`（依据引用数组）随 `done` 事件回传。
|
||||
- `done` 事件 payload 新增 `message_id`（助手消息落库真实 id）与 `user_message_id`，用于前端锚点 ID 原地替换（见 8.1）。
|
||||
|
||||
---
|
||||
|
||||
## 七、 前端架构设计 (Frontend Architecture)
|
||||
|
||||
### 7.1 锚点定位协议 `navigateToAnchor`（唯一公共底座）
|
||||
|
||||
新增 `web/src/engine/anchorNavigator.ts`：
|
||||
|
||||
```typescript
|
||||
export interface AnchorTarget {
|
||||
messageId: number; // 服务端数字 id (chat_messages.id)
|
||||
sessionId: string;
|
||||
highlightMs?: number; // 高亮脉冲时长, 默认 1800
|
||||
}
|
||||
|
||||
export async function navigateToAnchor(
|
||||
target: AnchorTarget,
|
||||
ctx: ChatWindowContext // 由 useChatWindow 提供: 已加载日集合、容器 ref、拉日 API
|
||||
): Promise<void> {
|
||||
// 1. 快路径: 锚点消息已在当前窗口 DOM 中
|
||||
// el = document.getElementById(`chat-anchor-${target.messageId}`)
|
||||
// el.scrollIntoView({ block: 'center', behavior: 'auto' }) ← 全程禁用 smooth
|
||||
// 触发高亮脉冲 class, highlightMs 后移除
|
||||
// 2. 慢路径: 不在窗口 → 调 GET /chat/messages/day?date=&anchor_id=&context=50
|
||||
// 将返回的日分片插入窗口日栈(去重合并, 保持正序),
|
||||
// 等 nextTick DOM 渲染完成后再执行 1 的定位逻辑
|
||||
// 3. 超时兜底: 拉取 > 3000ms 时 toast 提示"正在定位历史消息..."
|
||||
}
|
||||
```
|
||||
|
||||
**DOM 锚点约定**：`MessageBubble` 根元素固定 `id={`chat-anchor-${serverId}`}`；流式临时消息（尚无 serverId）不挂 DOM 锚点。**深链**：定位成功后同步 `location.hash = `#/s/{sessionId}/m/{messageId}``，工作台启动时解析该 hash 自动执行一次 `navigateToAnchor`（团队内分享"结论位置"场景，无需引入路由库）。
|
||||
|
||||
### 7.2 `useChatWindow` 状态机（新增 `web/src/hooks/useChatWindow.ts`）
|
||||
|
||||
```typescript
|
||||
type WindowState =
|
||||
| { phase: 'loading_window' } // 首屏拉 7 日
|
||||
| { phase: 'ready' } // 可交互
|
||||
| { phase: 'loading_older'; oldestDay: string } // 触顶拉更早日
|
||||
| { phase: 'anchoring'; targetId: number }; // 锚点慢路径中
|
||||
|
||||
interface ChatWindowContext {
|
||||
dayStack: ChatDayBucket[]; // 正序日分片栈(渲染顺序)
|
||||
state: WindowState;
|
||||
loadOlder(): Promise<void>; // 触顶加载(滚动补偿)
|
||||
jumpToDate(dayKey: string): Promise<void>; // 日期跳转: 替换为该日窗口再定位首条
|
||||
navigateToAnchor(target: AnchorTarget): Promise<void>;
|
||||
appendLiveMessage(msg: ChatMessage): void; // SSE 新消息(仅收尾落 id 后入栈)
|
||||
}
|
||||
```
|
||||
|
||||
**三条硬规则**：
|
||||
|
||||
1. **首屏瞬时落底**：窗口数据渲染完成后，在 `useLayoutEffect` 中执行 `container.scrollTop = container.scrollHeight`（同步、无动画、无闪烁）。原 `MessageStream` 的 `scrollIntoView({behavior:'smooth'})` **删除**，改为：仅当"新消息到达 && 用户距底部 < 80px"时才 `scrollIntoView({behavior:'smooth'})` 跟随；
|
||||
2. **触顶滚动补偿**：`loadOlder()` 先记录 `prevHeight = container.scrollHeight`，setState prepend 完成后在 `useLayoutEffect` 中 `container.scrollTop += container.scrollHeight - prevHeight`，视口内容零跳动；
|
||||
3. **窗口容量保护**：`dayStack` 上限 31 日 / 3000 条（超限从最早日**出栈**，锚点慢路径可随时找回），防长浏览会话内存膨胀。
|
||||
|
||||
### 7.3 `MessageStream` 改造对照
|
||||
|
||||
| 现状 | 改造后 |
|
||||
| :--- | :--- |
|
||||
| `messages.map` 全量渲染 | 按 `dayStack` 渲染：`DayDivider`（日期 + 条数 + truncated 提示）+ 当日消息 |
|
||||
| 每次变化 `smooth` 滚底 | 仅"新消息 && 用户在底部"时 smooth 跟随；恢复/跳转一律 `auto` |
|
||||
| 无触顶感知 | `onScroll` 监听 `scrollTop < 120` 触发 `loadOlder`（防抖 300ms，加载中不重入） |
|
||||
| 气泡无 DOM id | `id={`chat-anchor-${serverId}`}` + 引用按钮（见 8.2） |
|
||||
| `messages.filter(sessionId)` 全量过滤 | 数据源即当前会话窗口，不再全量 filter |
|
||||
|
||||
### 7.4 `HistoryTimelineRail` 历史导航侧栏（新增 `web/src/components/history/`）
|
||||
|
||||
置于工作台左栏会话列表下方的可展开 Tab（或独立抽屉，与现有 `LeftRail` / `deckDrawerOpen` 交互习惯一致）：
|
||||
|
||||
| 子组件 | 职责 | 数据源 |
|
||||
| :--- | :--- | :--- |
|
||||
| `DigestTimeline` | 每日摘要卡片流：headline、要点折叠、产出/决策徽标、"跳到当日"按钮（→ `jumpToDate` → 定位 `first_message_id`） | `GET /chat/digests` |
|
||||
| `CategoryFilterBar` | 分类 chips（含计数）：点击后**窗口内过滤高亮**（非裁剪）+ "仅看此分类"模式（消息流置灰非目标类，侧栏列出该类全部锚点，点击逐个跳） | `GET /chat/categories` |
|
||||
| `HistoryCalendar` | 轻量手写月历（零新依赖，与现有手写 UI 风格一致）：有消息日期打点（数量映射点径），点选 → `jumpToDate` | `GET /chat/dates` |
|
||||
| `ChatSearchPanel` | 搜索框 + 模式切换（综合/关键词/语义）+ 日期/分类过滤；结果按日分组、摘录高亮、点击 → `navigateToAnchor` | `GET /chat/search` |
|
||||
| `MilestoneList` | 关键节点列表（阶段推进/审批通过/报价确认），点击 → 锚点定位 `detail.message_id` | `project_activities (is_milestone)` 既有接口扩展 |
|
||||
|
||||
### 7.5 前端类型扩展（`web/src/types/workbench.ts`）
|
||||
|
||||
```typescript
|
||||
export interface ChatMessage { // 既有字段全部保留, 新增:
|
||||
serverId?: number; // 服务端数字 id = 锚点; SSE 期间为空, done 后回填
|
||||
dayKey?: string; // "2026-09-10"
|
||||
category?: MessageCategory; // milestone|file|review|task|consult|casual|system|uncategorized
|
||||
quotes?: QuotedMessage[]; // 本条消息携带的引用(用户主动引用 或 助手依据引用)
|
||||
}
|
||||
|
||||
export interface QuotedMessage {
|
||||
messageId: number; // 被引用消息锚点(软删除时仍展示 excerpt)
|
||||
excerpt: string; // 快照摘录(≤80 字, 引用兜底)
|
||||
authorName: string;
|
||||
dayKey: string;
|
||||
deleted?: boolean;
|
||||
}
|
||||
```
|
||||
|
||||
### 7.6 localStorage 存储策略迁移（`web/src/data/storage.ts`）
|
||||
|
||||
| 项 | 迁移前 | 迁移后 |
|
||||
| :--- | :--- | :--- |
|
||||
| 消息持久化 | `STORAGE_KEYS.MESSAGES` 全量存所有会话消息 | **废弃**。仅存 `chat.window.{sessionId}`（当前会话窗口快照，LRU 3 会话，供弱网/二次打开秒显骨架）+ `chat.draft.{sessionId}`（输入草稿与待发送引用） |
|
||||
| 迁移期兼容 | — | 首次启动检测旧 `MESSAGES` 键：调用 `POST /api/v1/chat/messages/import`（P0 提供一次性回填端点，仅 dev/demo 环境启用，生产默认关闭）后清除旧键 |
|
||||
| 会话/交付物 | localStorage | 维持现状（不在本期范围） |
|
||||
|
||||
---
|
||||
|
||||
## 八、 消息 ID 稳定性与引用互链协议 (ID Stability & Quoting)
|
||||
|
||||
### 8.1 锚点 ID 稳定性协议（SSE 临时 id → 服务端真实 id）
|
||||
|
||||
```
|
||||
用户发送 → 前端生成临时 id "tmp-{uuid}" (仅本次会话生命周期, 不落 localStorage)
|
||||
→ POST /chat/stream (SSE)
|
||||
→ done 事件: { message_id: 1090, user_message_id: 1089, ... }
|
||||
→ 前端将两条消息的 id 原地替换: tmp → serverId (React key 同步更新)
|
||||
→ 此后该消息即具锚点资格 (DOM id 挂载, 可被引用/搜索命中/摘要统计)
|
||||
```
|
||||
|
||||
- 服务端：`RecordUserMessage` 已返回影响的 `chat_messages.id`（pgx `RETURNING id` 扩展），SSE `done` 聚合回传（衔接既有 `sourceUserMessageId` 机制）；
|
||||
- 前端：替换期间保持组件状态不重置（按内容指纹匹配替换，避免流式动画闪断）；
|
||||
- 兜底：`done` 丢失真实 id 时（异常流），下一次打开会话经窗口接口自然取回真实 id，临时 id 不持久化故无污染。
|
||||
|
||||
### 8.2 引用交互（双向）
|
||||
|
||||
**用户引用**（InputArea + 引用选择器）：
|
||||
1. 任意气泡 hover 出现"引用"按钮（仅具 `serverId` 的消息）；
|
||||
2. 点击后进入"引用待选"态：输入区上方展示 `QuoteChip`（可移除），支持连续多选（≤3）；
|
||||
3. 选择器内置两级：最近 50 条 + 搜索选择（复用 `ChatSearchPanel` 结果点击即选入）；
|
||||
4. 发送时 `quote[]` 随 SSE body 上行，服务端写入用户消息 `metadata.quote`。
|
||||
|
||||
**智能体引用**（回复依据）：
|
||||
- 助手回复涉及历史结论时（如"基于 9 月 8 日您确认的 200 万预算"），协调层在 `metadata.quotes` 中回填依据消息锚点数组（来源：`RestoreSessionContext` 命中的事实消息 / 案例推荐依据）；
|
||||
- `MessageBubble` 渲染 `QuoteCard`：作者 + 日期 + 摘录快照，点击 → `navigateToAnchor`；
|
||||
- 被引用消息软删除：`deleted=true` 时卡片置灰显示"原消息已删除"，仅展示快照。

## 九、 离线降级与异常处理规范 (Error Handling & Fallback)
|
||||
|
||||
| 故障面 | 降级策略 |
|
||||
| :--- | :--- |
|
||||
| Embedder 服务不可用（语义搜索） | 复用既有 `DeterministicEmbedder`（1024 维语义哈希投影）离线降级，语义档自动退化为"确定性向量召回"，UI 标注"语义检索降级中" |
|
||||
| LLM 摘要失败 | 自动落规则摘要（`source=rule, status=fallback`）：要点=用户消息首句截断、决策=`metadata.milestone`、产出=`file_op`，复用 `summarizer.go` 确定性思路；连续失败 3 次标记 `failed` 并在侧栏展示"摘要暂不可用" |
|
||||
| 数据库不可用 | 沿用 ContextManager 双轨：内存切片等价窗口化（单测零依赖）；摘要/搜索内存版仅支持关键词档；窗口接口返回内存快照 |
|
||||
| 窗口接口超时（弱网） | 前端骨架屏 + `chat.window.{sessionId}` 本地快照秒显，后台静默刷新替换 |
|
||||
| 锚点目标消息不存在（已删/权限外） | 接口 404 → toast"该消息已不存在或无权访问"；引用卡片走快照兜底 |
|
||||
| 单日爆量（任务流 >300 条） | 窗口截断最新 300 条 + `truncated` 标记 + DayDivider 提示"本日共 N 条"，点击经游标翻全量 |
|
||||
| 搜索查询为空/过短（<2 字符） | 400 + 前端禁用搜索按钮，提示最小查询长度 |
|
||||
| localStorage 配额溢出 | 窗口快照写入 try-catch 静默失败（既有 `safeSetItem` 习惯），仅丢快照不丢功能 |
|
||||
|
||||
---
|
||||
|
||||
## 十、 性能预算与验收指标 (Performance Budget)
|
||||
|
||||
| 指标 | 预算（P95） | 测量口径 |
|
||||
| :--- | :--- | :--- |
|
||||
| 会话首屏定位到最新消息 | ≤ 300ms（渲染完成至落底，本地）；≤ 800ms（含网络） | `performance.mark` 打点：window 响应到达 → `scrollTop` 落底完成 |
|
||||
| 触顶加载上一日（1 日分片） | ≤ 500ms | 网络请求发起 → prepend 渲染 + 滚动补偿完成 |
|
||||
| 锚点跳转（已在窗口） | ≤ 50ms | 点击 → `scrollIntoView` 完成 |
|
||||
| 锚点跳转（跨日慢路径） | ≤ 800ms | 点击 → 拉日 + 插入 + 定位 + 高亮启动 |
|
||||
| 搜索（hybrid） | ≤ 1.5s（含 embedding） | 请求发起 → 结果渲染 |
|
||||
| 每日摘要懒生成 | 后台 ≤ 60s，不阻塞任何 UI | 触发 → `status=ready` |
|
||||
| 首屏 DOM 气泡数 | ≤ 300 | `MAX_MSG_PER_DAY × 7` 截断保证 |
|
||||
| `dayStack` 内存 | ≤ 3000 条消息 | 窗口容量保护规则保证 |
|
||||
|
||||
**压测种子**：新增 `scripts/build_long_history_seed.py`（参照既有 `build_neuropulse_demo_seed.py` 风格），生成 1 会话 / 90 天 / 12000 条（含任务流单日 500 条的爆量日），用于上述全部指标的自动化测量。
|
||||

|
||||
|
||||
## 十一、 实施阶段划分 (Phased Implementation)
|
||||
|
||||
> 遵循仓库"按功能层次拆分，过程逐步提交"规范：`feat(db)` → `feat(agent)` → `feat(api)` → `test(...)` → `docs(...)`。
|
||||
|
||||
### P0 — 止血：首屏直达与按日窗口（最高优先级，先解决"打开慢 + 滚动过程"）
|
||||
|
||||
1. `feat(db)`: `day_key`/`category` 增列 + 索引 + 存量回填（4.1）；`RecordUserMessage` 写入打标；
|
||||
2. `feat(agent)`: `GetChatWindow` / `GetChatDayMessages` / `ListChatDates`（内存双轨）；
|
||||
3. `feat(api)`: `GET /chat/messages/window`、`GET /chat/messages/day`、`GET /chat/dates`；
|
||||
4. 前端：`useChatWindow` + `MessageStream` 窗口化改造 + **删除 smooth 落底** + `DayDivider` + 触顶补偿加载 + localStorage 窗口化迁移；
|
||||
5. `test`: `chat_window_test.go` / `chat_window_api_test.go` / `useChatWindow.test.ts` + 压测种子脚本。
|
||||
**P0 验收**：90 天 12000 条种子下，打开会话 P95 ≤ 300ms 落底且**全程无肉眼可见滚动过程**。
|
||||
|
||||
### P1 — 导航体系：锚点 / 分类 / 日期跳转 / 引用
|
||||
|
||||
1. 锚点协议 `anchorNavigator.ts` + DOM id + 深链 hash；
|
||||
2. `GET /chat/categories` + `CategoryFilterBar` + 分类锚点列表；
|
||||
3. `HistoryCalendar` + `jumpToDate`（定位当日首条）；
|
||||
4. SSE `done` 回传真实 id（8.1）+ 用户引用（引用选择器/QuoteChip/上行 quote）+ `QuoteCard` 渲染与点击定位。
|
||||
|
||||
### P2 — 智能层：搜索 / 每日摘要 / 时间轴侧栏
|
||||
|
||||
1. `pg_trgm` + `chat_message` 选择性向量化 + `GET /chat/search` + `ChatSearchPanel`；
|
||||
2. `chat_daily_digests` 表 + `DailyDigestGenerator`（LLM + 规则降级）+ `Scheduler`（定时/懒生成/当日节流增量）+ `GET|POST /chat/digests`；
|
||||
3. `DigestTimeline` + `MilestoneList`（`project_activities` 扩展 `detail.message_id`）；
|
||||
4. 摘要向量化沉淀 `daily_digest` domain（打通语义记忆体系）。
|
||||
|
||||
### P3 — 增强（按需排期）
|
||||
|
||||
1. 虚拟滚动（`@tanstack/react-virtual`，动态高度 Dynamic mode，需评估与触顶补偿/锚点定位的配合）；
|
||||
2. 聊天记录导出（复用已有 `docx`/`xlsx` 依赖：按日/按分类导出带锚点编号的记录，合规审计场景）；
|
||||
3. 未读提醒（协同会话同事新消息 → 时间轴日期轴未读角标）；
|
||||
4. CLI 锚点支持（`bizdev-cli --goto-msg {id}` 简单定位）；
|
||||
5. 结项项目对话冷归档（`chat_messages` 活跃项目热表 → 归档表，配合项目生命周期状态机）。
|
||||

|
||||
## 十二、 质量验收与测试方案 (Test & Quality Gate)
|
||||
|
||||
### 12.1 Go 单元与集成测试（`go test ./...`）
|
||||
|
||||
| 测试文件 | 覆盖 |
|
||||
| :--- | :--- |
|
||||
| `internal/ctxmgr/chat_window_test.go` | 窗口 7 日取数、`before_day` 分段、单日截断、日查询锚点上下文、日期列表、内存双轨等价性 |
|
||||
| `internal/ctxmgr/chat_search_test.go` | keyword/fuzzy/semantic/hybrid 四档、RBAC 私聊过滤、日期与分类过滤、空查询拒绝 |
|
||||
| `internal/ctxmgr/chat_digest_test.go` | LLM 成功路径（stub Backend）、规则降级路径、幂等（重复生成）、当日增量 `digest_version`、懒生成占位 |
|
||||
| `internal/ctxmgr/chat_category_test.go` | `DeriveMessageCategory` 全词表短路优先级、`day_key` 时区归属（CHAT_TZ 边界 00:00 前后消息） |
|
||||
| `internal/server/chat_window_api_test.go` | 6.1–6.6 全端点契约、错误码、SSE `done` 携带 `message_id`/`user_message_id` 与 `quote` 透传 |
|
||||
|
||||
### 12.2 Web 单元测试（`npm test`：`tsx --test` + vitest，遵循现有 test script 排除模式）
|
||||
|
||||
| 测试文件 | 覆盖 |
|
||||
| :--- | :--- |
|
||||
| `web/src/hooks/useChatWindow.test.ts` | 状态机流转、触顶滚动补偿数值、窗口容量出栈、首屏落底调用 |
|
||||
| `web/src/engine/anchorNavigator.test.ts` | 快路径定位、慢路径拉日插入后定位、404 兜底、hash 深链生成与解析 |
|
||||
| `web/src/components/history/DayDivider.test.ts`（及各子组件） | truncated 提示、分类计数渲染、日历打点、QuoteCard 快照兜底 |
|
||||
|
||||
### 12.3 真实 E2E 与性能验收
|
||||
|
||||
1. `scripts/run_history_navigation_e2e.py`（参照 `run_real_e2e_blackbox.py` 风格）：六大用户故事全链路——
|
||||
a. 打开 90 天老会话 → 断言首屏窗口 7 日 + 无滚动动画（前端上报 `performance` 打点）；
|
||||
b. 触顶连续加载至 31 日上限；
|
||||
c. 分类筛选 → 里程碑锚点跳转；
|
||||
d. 搜索"预算" → hybrid 命中 → 锚点定位；
|
||||
e. 引用历史消息发送 → 回复 `QuoteCard` 点击定位；
|
||||
f. 查看每日摘要 → 跳转目标日首条；
|
||||
2. 性能脚本断言第十章全部 P95 预算（超预算即测试失败）；
|
||||
3. 测试报告统一归档 `.doc/test-reports/2026-09-10-chat-history-navigation-test-report.md`。

## 十三、 风险与开放问题 (Risks & Open Questions)
|
||||
|
||||
| # | 风险/问题 | 应对策略 | 状态 |
|
||||
| :--- | :--- | :--- | :--- |
|
||||
| 1 | 时区与跨日边界（凌晨消息归属、服务器 UTC 与业务日不一致） | `CHAT_TZ` 配置统一（默认 Asia/Shanghai），`day_key` 只由应用层一处计算；边界用例进单测 | 已决策 |
|
||||
| 2 | 单日消息爆量（长任务 SSE 产生数百条助手消息） | `MAX_MSG_PER_DAY=300` 截断 + 游标翻全量 + 锚点上下文补齐，双层兜底 | 已决策 |
|
||||
| 3 | 语义搜索成本（全量向量化 token/存储开销） | 选择性向量化（用户消息 + completed 助手终稿 + 每日摘要），失败自动降级确定性向量 | 已决策 |
|
||||
| 4 | 每日摘要质量（LLM 幻觉、要点失真） | 输出强制 JSON Schema + `source` 标注 + 人工"重新生成"入口；摘要仅导航用途不作为合规依据 | 已决策 |
|
||||
| 5 | 前端旧 localStorage 数据迁移（demo 数据 vs 真实数据混杂） | `POST /chat/messages/import` 仅 dev/demo 启用；生产默认走后端种子 | 待评审确认环境开关 |
|
||||
| 6 | 虚拟滚动与锚点定位/触顶补偿的兼容（P3） | 按需专项评估（动态高度测量 + `scrollTo` offset 计算），不阻塞 P0-P2 | 开放 |
|
||||
| 7 | 多端一致（CLI / Web 锚点语义统一） | P3 提供 CLI `--goto-msg`；锚点 id 语义（服务端数字 id）已两端无关 | 开放 |
|
||||
| 8 | 结项冷归档对既有查询的影响（P3） | 归档表与热表同构，查询层加 `project.status` 路由；预留 `deleted_at` 之外的 `archived_at` 扩展位 | 开放 |
|

## 附：与既有能力的复用关系总表
|
||||
|

| 既有能力 | 本设计复用方式 |
|
||||
| :--- | :--- |
|
||||
| `chat_messages` / `chat_sessions` 持久化 | 增列演进，不动主键与既有索引 |
|
||||
| `context_memory_chunks` + pgvector + HNSW | 扩展 domain（`chat_message` / `daily_digest`）承载语义搜索与摘要沉淀 |
|
||||
| `DeterministicEmbedder` 离线降级 | 语义搜索/摘要 embedding 降级直接复用 |
|
||||
| `internal/agent` Backend（pi-agent + MiniMax） | 每日摘要 LLM 生成器注入 |
|
||||
| `summarizer.go` 确定性抽取思路 | 摘要规则降级路径 |
|
||||
| `project_activities`（activity_type / is_milestone） | 分类词表对齐 + 里程碑导航数据源 |
|
||||
| `sourceUserMessageId` / SSE 状态机 | 消息 ID 稳定性协议衔接 |
|
||||
| `docx` / `xlsx` 前端依赖 | P3 聊天记录导出 |
|
||||
| `internal/bizdev/service.go` 心跳 goroutine 模式 | DigestScheduler 生命周期管理 |
