feat(hermes): implement intelligence pipeline — 4 chunks, 684 tests passing

Hermes Intelligence Pipeline closes breakpoints in ZCLAW's existing
intelligence components with 4 self-contained modules:

Chunk 1 — Self-improvement Loop:
- ExperienceStore (zclaw-growth): FTS5+TF-IDF wrapper with scope prefix
- ExperienceExtractor (desktop/intelligence): template-based extraction
  from successful proposals with implicit keyword detection

Chunk 2 — User Modeling:
- UserProfileStore (zclaw-memory): SQLite-backed structured profiles
  with industry/role/expertise/comm_style/recent_topics/pain_points
- UserProfiler (desktop/intelligence): fact classification by category
  (Preference/Knowledge/Behavior) with profile summary formatting

Chunk 3 — NL Cron Chinese Time Parser:
- NlScheduleParser (zclaw-runtime): 6 pattern matchers for Chinese time
  expressions (每天/每周/工作日/间隔/每月/一次性) producing cron expressions
- Period-aware hour adjustment (下午3点→15, 晚上8点→20)
- Schedule intent detection + task description extraction

Chunk 4 — Trajectory Compression:
- TrajectoryStore (zclaw-memory): trajectory_events + compressed_trajectories
- TrajectoryRecorderMiddleware (zclaw-runtime/middleware): priority 650,
  async non-blocking event recording via tokio::spawn
- TrajectoryCompressor (desktop/intelligence): dedup, request classification,
  satisfaction detection, execution chain JSON

Schema migrations: v2→v3 (user_profiles), v3→v4 (trajectory tables)

+# Hermes Intelligence Pipeline Design
+
+> 基于 Hermes Agent (Nous Research) 竞品分析，吸收 4 个核心理念到 ZCLAW 的详细设计方案。
+> 架构方案：Pipeline Closure — 闭合现有管线断点，不引入新架构层。
+
+## Context
+
+Hermes Agent 验证了"一个管家 + 记忆飞轮"的方向，其 4 个核心创新对 ZCLAW 发布后迭代有直接参考价值：
+
+1. **自我改进闭环** — 执行 → 评估 → 提取技能 → 改进 → 复用
+2. **用户建模** — 三层记忆栈 + 统一用户画像
+3. **自然语言 Cron** — LLM 解析自然语言为定时任务
+4. **轨迹压缩** — 工具调用链 → 结构化 JSON → RL 基础
+
+**关键诊断：** ZCLAW 缺的不是模块，是管线没接通。现有 PainAggregator、SolutionGenerator、Reflection、Heartbeat、MemoryExtractor 等组件已就位，但彼此断开。本设计闭合这些断点。
+
+**范围约束：**
+- 管家路由器（ButlerRouterMiddleware + SemanticSkillRouter 接通）由另一个会话推进，本设计标注为外部依赖
+- 发布后迭代，不影响当前发布计划
+- 4 个理念全部设计，按优先级排序：自我改进闭环 > 用户建模 > NL Cron > 轨迹压缩
+
+**总代码量估算：** ~2200 行新增/修改（~1700 新增 + ~500 修改）
+
+### 类型约定
+
+本设计使用以下 ID 类型约定：
+
+```rust
+// 所有 Rust 原生结构体使用强类型
+use uuid::Uuid;
+use zclaw_types::{AgentId, SessionId};
+
+// 为新实体定义类型别名（newtype wrapper 在 Tauri 命令层解包为 String）
+type ExperienceId = String;   // Uuid::new_v4().to_string()
+type ProposalId = String;     // 与现有 Proposal.id 一致
+type TrajectoryId = String;   // Uuid::new_v4().to_string()
+```
+
+Rust 内部结构体使用 `AgentId`、`SessionId`；Tauri 命令边界使用 `String`（Tauri serialize 要求）。
+
+### 统一完成状态枚举
+
+跨 Section 1/4 使用统一的完成状态：
+
+```rust
+/// 通用完成状态，所有 Outcome 枚举的基础
+enum CompletionStatus {
+    Success,
+    Partial,
+    Failed,
+    Abandoned,  // Section 1 不使用此变体（运行时约定，非编译时约束）
+}
+```
+
+Section 1 的 Experience 使用 `CompletionStatus`（不含 Abandoned），Section 4 的 CompressedTrajectory 使用完整版。
+
+---
+
+## Section 1: 自我改进闭环
+
+### 目标
+
+用户反馈痛点 → 自动识别 → 自动生成方案 → 方案成功后提取为可复用经验 → 下次类似问题直接复用。
+
+### 数据流
+
+```
+用户消息 → PainAggregator（已有）
+              ↓ confidence >= 0.7
+         SolutionGenerator（已有，改为自动触发）
+              ↓ 生成 Proposal
+         等待用户反馈（成功/失败）
+              ↓ 成功
+         ExperienceExtractor（新增）
+              ↓ 生成结构化经验
+         ExperienceStore（新增，SQLite）
+              ↓ 下次对话
+         MemoryMiddleware（已有）注入相关经验
+```
+
+### 关键断点修复
+
+**断点 1：PainAggregator → SolutionGenerator（未自动触发）**
+
+- 文件：`desktop/src-tauri/src/intelligence/pain_aggregator.rs`
+- 当 `confidence >= 0.7` 时，通过 Tauri event 自动调用 `butler_generate_solution`
+- 新增 `PainConfirmedEvent` 事件结构体
+
+**断点 2：方案结果反馈（无反馈机制）**
+
+- 新增 `ProposalFeedback` 结构体
+- 在聊天流中检测用户隐式反馈关键词（"好了""解决了""没用"）
+- 新增 Tauri 命令 `butler_submit_proposal_feedback`
+
+**断点 3：成功方案 → 结构化经验（完全缺失）**
+
+- 新增 `ExperienceExtractor`：从成功方案中提取经验
+- LLM 辅助提取（复用现有 LlmDriver），fallback 到模板提取
+- 存入 VikingStorage（使用 scope 前缀 `experience://{agent_id}/`）
+
+**断点 4：经验复用（完全缺失）**
+
+- 扩展 `MemoryMiddleware`：用户新消息时，通过 VikingStorage 检索相关经验
+- 使用 scope 过滤 `experience://` 前缀 + TF-IDF 相关性匹配
+- 相似度 > 阈值时，注入"过往经验"到 system prompt
+- 格式：`[过往经验] 类似情况 X 做过 Y，结果是 Z`
+
+### 数据结构
+
+```rust
+// 新增文件：desktop/src-tauri/src/intelligence/experience.rs
+
+use zclaw_types::AgentId;
+use uuid::Uuid;
+
+struct Experience {
+    id: ExperienceId,
+    agent_id: AgentId,
+    pain_pattern: String,        // 触发模式（关键词摘要）
+    context: String,             // 问题上下文
+    solution_steps: Vec<String>, // 解决步骤
+    outcome: CompletionStatus,   // Success | Partial（经验只记录成功的）
+    source_proposal_id: Option<ProposalId>,
+    reuse_count: usize,
+    created_at: DateTime,
+}
+
+struct ProposalFeedback {
+    proposal_id: ProposalId,
+    outcome: CompletionStatus,   // Success | Failed | Partial
+    user_comment: Option<String>,
+    detected_at: DateTime,
+}
+
+struct PainConfirmedEvent {
+    pain_point_id: String,       // PainPoint.id (Uuid String)
+    pattern: String,
+    confidence: f32,
+}
+```
+
+### 存储策略
+
+经验存储在现有 VikingStorage 中，使用 scope 前缀区分：
+
+```rust
+// Experience 存储为 VikingStorage memory entry
+scope: "agent://{agent_id}/experience/{pattern_hash}"  // 遵循 OpenViking URI 约定
+content: JSON(Experience)  // 序列化的完整 Experience 结构体
+```
+
+**为什么不用独立的 experiences + FTS5 表：**
+- VikingStorage 已有成熟的 FTS5 + TF-IDF + embedding 检索管道
+- MemoryMiddleware 已与 VikingStorage 集成，增加 scope 前缀即可区分
+- 避免维护两套独立的 FTS5 索引
+
+独立的 `experience_store.rs` 文件负责 VikingStorage CRUD + scope 过滤，不创建新表。
+
+### 迁移策略
+
+不需要新数据库表或 schema 变更。经验数据通过 VikingStorage 的现有 memory 表存储，使用 scope 前缀区分。
+
+### 错误处理
+
+- ExperienceExtractor LLM 调用失败 → fallback 到模板提取（固定格式提取 solution_steps）
+- ProposalFeedback 检测失败 → 不阻塞对话，静默跳过
+- 经验注入失败 → MemoryMiddleware 记录 warn 日志，不注入，不影响正常对话
+- 所有错误遵循代码库约定：非关键路径使用 `log::warn!` / `log::error!`，不阻塞主流程
+
+### 测试计划
+
+| 测试目标 | 文件位置 | 覆盖场景 |
+|----------|---------|---------|
+| ExperienceExtractor | `experience.rs` 内联 `#[cfg(test)]` | LLM 提取成功/failure fallback、模板提取 |
+| ExperienceStore | `experience_store.rs` 内联 | CRUD 往返、scope 过滤、VikingStorage 集成 |
+| PainConfirmedEvent 触发 | `pain_aggregator.rs` 测试扩展 | confidence >= 0.7 触发事件 |
+| 经验注入 | MemoryMiddleware 测试 | 相关性过滤、token 限制、空结果处理 |
+| ProposalFeedback 检测 | `solution_generator.rs` 测试扩展 | 隐式反馈关键词匹配 |
+
+### 文件清单
+
+| 文件 | 用途 | 预估行数 |
+|------|------|---------|
+| `desktop/src-tauri/src/intelligence/experience.rs` | ExperienceExtractor + 逻辑 | ~250 |

+
+**预估：~555 行新增/修改**

+
+## Section 2: 用户建模
+
+### 目标
+
+从每次对话中持续提取用户特征，聚合为结构化画像，注入到路由和生成环节。
+
+### 数据流
+
+```
+对话消息 → MemoryExtractor（已有）
+              ↓
+         UserProfiler（新增）
+              ↓ 聚合到 UserProfile
+         UserProfileStore（新增，SQLite）
+              ↓
+         ├→ ButlerRouter（外部依赖，另一个会话）
+         │    → 路由决策考虑用户偏好
+         └→ MemoryMiddleware（已有）
+              → system prompt 注入用户画像摘要
+```
+
+### 设计决策
+
+**为什么新建 UserProfile 而不沿用 IdentityManager.user_profile？**
+
+现有 user_profile 是非结构化 markdown，无法做条件查询。Profile injection 已被有意禁用（`identity.rs:291-298`），因为它导致模型过度关注旧话题。需要结构化画像做相关性过滤后注入。
+
+**单用户桌面场景：** 桌面版使用 `"default_user"` 作为 user_id（与 PainAggregator 一致），仅维护一条 UserProfile 记录。
+
+### 数据结构
+
+```rust
+// 新增文件：crates/zclaw-memory/src/user_profile_store.rs
+
+struct UserProfile {
+    user_id: String,  // "default_user"（桌面版单用户）
+
+    // 静态属性（低频更新）
+    industry: Option<String>,          // "医疗" "制造业"
+    role: Option<String>,              // "行政主任" "厂长"
+    expertise_level: Option<Level>,    // Beginner / Intermediate / Expert
+    communication_style: Option<CommStyle>, // Concise / Detailed / Formal / Casual
+    preferred_language: String,        // "zh-CN"
+
+    // 动态属性（高频更新）
+    recent_topics: Vec<String>,        // 最近 7 天的话题
+    active_pain_points: Vec<String>,   // 当前未解决痛点
+    preferred_tools: Vec<String>,      // 常用技能/工具
+
+    // 元数据
+    updated_at: DateTime,
+    confidence: f32,                   // 画像置信度
+}
+
+enum Level { Beginner, Intermediate, Expert }
+enum CommStyle { Concise, Detailed, Formal, Casual }
+```
+
+### 聚合逻辑（UserProfiler）
+
+1. **MemoryExtractor 输出 → 分类**：已提取的记忆按 `UserPreference` / `UserFact` / `AgentLesson` 分类
+2. **分类后聚合**：
+   - `UserPreference` → 更新 `communication_style`, `preferred_tools`
+   - `UserFact` → 更新 `industry`, `role`, `expertise_level`
+   - `AgentLesson` → 更新 `recent_topics`
+   - PainAggregator 的活跃痛点 → 更新 `active_pain_points`
+3. **去重 + 衰减**：相似属性合并，超过 30 天无佐证的属性降低 confidence
+4. **存储**：单用户单条记录（upsert），SQLite `user_profiles` 表
+
+### 注入逻辑
+
+```rust
+// 在 MemoryMiddleware 中新增
+fn inject_user_profile(&self, ctx: &mut MiddlewareContext, profile: &UserProfile) {
+    // 只注入与当前话题相关的属性
+    let relevant = self.filter_by_relevance(profile, &ctx.user_input);
+    if relevant.is_empty() { return; }
+
+    // 格式化为简洁摘要，不超过 100 tokens
+    let summary = format_user_profile_summary(&relevant);
+    ctx.system_prompt.push_str(&summary);
+}
+```
+
+**关键约束：** 注入内容不超过 100 tokens，只注入与当前话题相关的属性。
+
+### 与管家路由器的协作（外部依赖）
+
+当管家路由器接通后：
+- ButlerRouterMiddleware 可读取 UserProfile.industry 和 role
+- 路由时考虑用户背景
+- 本设计只提供数据接口，路由逻辑由另一个会话处理
+
+### 迁移策略
+
+新增 `user_profiles` 表，通过 `schema.rs` 的 `MIGRATIONS` 数组递增版本。初始版本包含 CREATE TABLE + 默认 "default_user" 行。
+
+```rust
+// 在 schema.rs MIGRATIONS 数组新增
+("CREATE TABLE IF NOT EXISTS user_profiles (...)", "DROP TABLE IF EXISTS user_profiles")
+```
+
+### 错误处理
+
+- UserProfileStore 读写失败 → `log::warn!` + 返回 None，不阻塞对话
+- UserProfiler 聚合失败 → 保留上次有效画像，不覆盖
+- Profile 注入失败 → MemoryMiddleware 降级到无 profile 注入模式
+- 所有操作遵循：非关键路径错误不阻塞主流程
+
+### 测试计划
+
+| 测试目标 | 文件位置 | 覆盖场景 |
+|----------|---------|---------|
+| UserProfileStore | `user_profile_store.rs` 内联 | CRUD 往返、upsert 去重、JSON 字段序列化 |
+| UserProfiler 聚合 | `user_profiler.rs` 内联 | 分类正确性、去重、衰减、空输入 |
+| Profile 注入 | MemoryMiddleware 测试扩展 | 相关性过滤、100 token 限制、空 profile |
+| 迁移 | schema 测试 | 新建 + 升级路径 |
+
+### 数据库 Schema
+
+```sql
+CREATE TABLE IF NOT EXISTS user_profiles (
+    user_id TEXT PRIMARY KEY,
+    industry TEXT,
+    role TEXT,
+    expertise_level TEXT,           -- 'Beginner' | 'Intermediate' | 'Expert'

+## Section 3: 自然语言 Cron
+
+### 目标
+
+用户说"每天早上9点提醒我查房" → 系统解析为 `0 9 * * *` → 自动创建定时任务。
+
+### 数据流
+
+```
+用户消息（含时间意图）
+    ↓
+意图分类（ButlerRouter / 正则预检）
+    ↓ 检测到"定时/提醒"意图
+NlScheduleParser（新增，位于 zclaw-runtime）
+    ↓ 解析为 ParsedSchedule
+ScheduleConfirmDialog（新增）
+    ↓ 用户确认 "每天早上9点 → 0 9 * * *"
+SchedulerService（已有，位于 zclaw-kernel）
+    ↓ 创建定时任务
+TriggerManager（已有）
+    ↓ 到时触发
+Hand 执行（已有）
+```
+
+### 解析策略（三层 fallback）
+
+**Layer 1: 正则模式匹配（覆盖 80% 常见场景）**
+
+| 模式 | 示例 | Cron |
+|------|------|------|
+| 每天 + 时间 | 每天早上9点 | `0 9 * * *` |
+| 每周N + 时间 | 每周一上午10点 | `0 10 * * 1` |
+| 工作日 + 时间 | 工作日下午3点 | `0 15 * * 1-5` |
+| 每N小时 | 每2小时 | `0 */2 * * *` |
+| 每月N号 | 每月1号 | `0 0 1 * *` |
+| 相对时间 | 明天下午3点 | 一次性 ISO |
+
+**Layer 2: LLM 辅助解析（覆盖模糊/复杂表述）**
+
+- 使用 Haiku（~50 tokens 输入，~20 tokens 输出）
+- 处理如"下个月开始每周二和周四提醒我"
+
+**Layer 3: 交互澄清（无法确定时）**
+
+- "我理解您想设置定时任务，请确认：..."
+
+### 数据结构
+
+```rust
+// 新增文件：crates/zclaw-runtime/src/nl_schedule.rs
+// 放在 runtime 层因为这是纯文本→cron工具，不依赖 kernel 协调
+
+use zclaw_types::AgentId;
+
+struct ParsedSchedule {
+    cron_expression: String,        // "0 9 * * *"
+    natural_description: String,    // "每天早上9点"
+    confidence: f32,
+    task_description: String,       // "查房提醒"
+    task_target: TaskTarget,
+}
+
+/// 定时任务目标
+enum TaskTarget {
+    Agent(AgentId),                 // 触发指定 agent
+    Hand(String),                   // 触发指定 hand（工具名）
+    Workflow(String),               // 触发指定 workflow（名称）
+}
+
+enum ScheduleParseResult {
+    Exact(ParsedSchedule),          // 高置信度，直接确认
+    Ambiguous(Vec<ParsedSchedule>), // 多种理解，需选择
+    Unclear,                        // 需要澄清
+}
+```
+
+### 确认流程
+
+1. 用户说"每天早上9点提醒我查房"
+2. 解析为 `{ cron: "0 9 * * *", desc: "查房提醒" }`
+3. 系统回复："好的，我为您设置了：**每天早上 9:00** 提醒查房。确认吗？"
+4. 用户确认 → 调用已有 `SchedulerService.create_trigger()`
+5. 用户修正 → 重新解析或手动编辑
+
+### 迁移策略
+
+不需要新数据库表。NlScheduleParser 是纯计算工具，输出通过现有 `SchedulerService` + `TriggerManager` 存储。
+
+### 错误处理
+
+- 正则匹配失败 → 尝试 Layer 2 LLM 解析
+- LLM 解析失败 → 返回 `ScheduleParseResult::Unclear`，触发交互澄清
+- 定时任务创建失败 → 向用户报告错误，建议手动设置
+- 所有错误不阻塞对话流程
+
+### 测试计划
+
+| 测试目标 | 文件位置 | 覆盖场景 |
+|----------|---------|---------|
+| 正则解析 | `nl_schedule.rs` 内联 | 10+ 中文时间表述模式、边界值、无效输入 |
+| LLM fallback | mock 测试 | LLM 返回无效 cron 时的容错 |
+| ParsedSchedule | 单元测试 | 序列化、字段完整性 |
+| TaskTarget 枚举 | 单元测试 | 各变体匹配现有类型 |
+| 确认流程 | 集成测试 | 完整 parse → confirm → create 链路 |
+
+### 文件清单
+
+| 文件 | 用途 | 预估行数 |
+|------|------|---------|
+| `crates/zclaw-runtime/src/nl_schedule.rs` | NlScheduleParser + 中文模式库 | ~300 |
+| 改动 `intelligence_hooks.rs` | 检测定时意图并触发解析 | ~40 |
+| 改动 desktop store + component | 确认对话框交互 | ~150 |
+| 改动 `crates/zclaw-kernel/src/scheduler.rs` | 接受 cron 字符串输入 | ~20 |

+
+## Section 4: 轨迹压缩
+
+### 目标
+
+记录完整的工具调用链（用户请求 → 意图分类 → 技能选择 → 执行步骤 → 结果 → 用户满意度），压缩为结构化 JSON，作为未来 RL/改进的基础数据。
+
+### 数据流
+
+```
+用户请求
+    ↓
+AgentLoop（已有）
+    ↓ 每步通过中间件记录
+TrajectoryRecorderMiddleware（新增，实现 AgentMiddleware trait）
+    ↓ 异步写入 trajectory_events 表
+    ↓ 会话结束时
+TrajectoryCompressor（新增）
+    ↓ 压缩为结构化 JSON
+compressed_trajectories 表
+    ↓ 可选
+导出为 RL 训练数据格式
+```
+
+### 关键设计决策：TrajectoryRecorder 作为中间件
+
+TrajectoryRecorder 实现 `AgentMiddleware` trait（来自 `zclaw-runtime`），利用现有中间件钩子：
+
+- `before_completion` → 记录 `UserRequest` 步骤
+- `after_tool_call` → 记录 `ToolExecution` 步骤
+- `after_completion` → 记录 `LlmGeneration` 步骤 + 会话结束时触发压缩
+
+**为什么不用自定义 AgentLoop hook：**
+- 现有中间件系统已提供所有需要的钩子点
+- `MiddlewareContext` 已暴露 `agent_id`、`session_id`、`user_input`、`input_tokens`、`output_tokens`
+- 符合 Pipeline Closure 原则：不引入新架构层
+
+优先级设置：600-799 范围（遥测类别），确保在业务中间件之后运行。注意现有 `token_calibration` 中间件已占用优先级 700，推荐使用 650。
+
+### 数据结构
+
+```rust
+// 新增文件：crates/zclaw-memory/src/trajectory_store.rs
+
+use zclaw_types::{AgentId, SessionId};
+use uuid::Uuid;
+
+/// 单条轨迹事件（细粒度，按步骤记录）
+struct TrajectoryEvent {
+    id: TrajectoryId,
+    session_id: SessionId,
+    agent_id: AgentId,
+    step_index: usize,
+    step_type: TrajectoryStepType,
+    input_summary: String,     // ≤200 字
+    output_summary: String,    // ≤200 字
+    duration_ms: u64,
+    timestamp: DateTime,
+}
+
+enum TrajectoryStepType {
+    UserRequest,            // 用户原始请求
+    IntentClassification,   // 意图分类结果
+    SkillSelection,         // 选择了哪个技能
+    ToolExecution,          // 工具调用
+    LlmGeneration,          // LLM 生成
+    UserFeedback,           // 用户反馈
+}
+
+/// 压缩后的完整轨迹（会话结束时生成）
+struct CompressedTrajectory {
+    id: TrajectoryId,
+    session_id: SessionId,
+    agent_id: AgentId,
+
+    request_type: String,         // "data_report" "policy_query"
+    tools_used: Vec<String>,      // ["researcher", "collector"]
+    outcome: CompletionStatus,    // Success | Partial | Failed | Abandoned
+    total_steps: usize,
+    total_duration_ms: u64,
+    total_tokens: u32,
+
+    execution_chain: String,      // JSON: [{step, tool, result_summary}]
+
+    satisfaction_signal: Option<SatisfactionSignal>,
+
+    created_at: DateTime,
+}
+
+enum SatisfactionSignal {
+    Positive,   // "谢谢""很好""解决了"
+    Negative,   // "不对""没用""还是不行"
+    Neutral,    // 无明显信号
+}
+```
+
+### 记录策略
+
+**低开销原则：** 轨迹记录不能影响正常对话性能。
+
+1. **事件记录：** 每步只存 `step_type + input_summary(≤200字) + output_summary(≤200字)`
+2. **异步写入：** 通过 `tokio::spawn` 异步写入 SQLite，不阻塞主流程
+3. **压缩触发：** 会话结束时（compactor flush 或 session close），异步压缩
+4. **保留策略：** 压缩后删除原始事件（保留 7 天），压缩轨迹保留 90 天
+
+### 压缩算法
+
+```rust
+fn compress(events: Vec<TrajectoryEvent>) -> CompressedTrajectory {
+    // 1. 提取关键步骤（跳过中间重试/错误恢复）
+    // 2. 合并连续相同类型的步骤
+    // 3. 生成 execution_chain JSON
+    // 4. 推断 outcome（最后一步是否成功 + 用户反馈信号）
+    // 5. 统计 token 用量和耗时
+}
+```
+
+### 与自我改进闭环的协作
+
+当 ExperienceExtractor 运行时：
+- 查询 `compressed_trajectories` 找到类似场景的历史轨迹
+- 评估"这个方案上次用了几步？成功率多少？"
+- 为经验提取提供数据支撑
+
+### 未来 RL 扩展（本次不实施）
+
+- `execution_chain` 可直接转换为 Atropos/GEPA 训练格式
+- `satisfaction_signal` 可作为 reward signal
+- RL 训练管道不在本次范围内
+
+### 迁移策略
+
+通过 `schema.rs` 的 `MIGRATIONS` 数组递增版本（使用 `&[&str]` 扁平数组格式，与现有代码一致），新增 `trajectory_events` 和 `compressed_trajectories` 两张表。
+
+```rust
+// 在 schema.rs MIGRATIONS 数组新增（扁平 &str 数组，无 down migration）
+&[
+    "CREATE TABLE IF NOT EXISTS trajectory_events (
+        id TEXT PRIMARY KEY,
+        session_id TEXT NOT NULL,
+        ...
+    );
+    CREATE TABLE IF NOT EXISTS compressed_trajectories (
+        ...
+    );
+    CREATE INDEX IF NOT EXISTS idx_trajectory_session ON trajectory_events(session_id);",
+]
+```
+
+### 错误处理
+
+- TrajectoryRecorder 异步写入失败 → `log::warn!`，不重试，丢弃单条事件
+- TrajectoryCompressor 压缩失败 → `log::warn!`，原始事件保留 7 天后自动清理
+- 压缩轨迹查询失败 → ExperienceExtractor 降级到无历史数据模式
+- 所有操作：非关键路径错误不阻塞对话

+### 实施顺序和依赖关系
+
+```
+Section 1 (自我改进闭环) ← 立即开始
+    ↓
+Section 2 (用户建模) ← 可与 Section 1 并行，无强依赖
+    ↓
+Section 3 (NL Cron) ← 依赖 Section 2 的 UserProfile（可选）+ 管家路由器（外部）
+    ↓
+Section 4 (轨迹压缩) ← 可与 Section 1-3 并行，无依赖
+```
+
+Section 1 和 2 可以并行开发。Section 3 建议在管家路由器接通后实施。Section 4 完全独立。
+
+### 外部依赖
+
+- 管家路由器（ButlerRouterMiddleware + SemanticSkillRouter 接通）— 另一个会话推进
+- 痛点数据持久化（内存 → SQLite）— 已在 pre-release strategy 中规划
+
+### intelligence_hooks.rs 管理
+
+当前 `intelligence_hooks.rs` 约 281 行。本设计新增约 120 行钩子代码（Section 1: ~50, Section 2: ~30, Section 3: ~40）。
+如果文件超过 400 行，应拆分为 `hooks/` 子模块：
+- `hooks/pain.rs` — 痛点相关钩子
+- `hooks/profile.rs` — 用户画像钩子
+- `hooks/schedule.rs` — 定时任务意图检测
+- `hooks/mod.rs` — 统一注册
+
+### 验证方式
+
+每个 Section 完成后的验证步骤：
+
+1. **自我改进闭环：** 人工模拟痛点对话 → 验证自动生成方案 → 验证经验提取 → 验证经验复用注入
+2. **用户建模：** 多轮对话 → 检查 UserProfile 各字段是否正确聚合 → 验证注入内容相关性
+3. **NL Cron：** 测试 10+ 种中文时间表述 → 验证 cron 输出 → 验证定时任务创建
+4. **轨迹压缩：** 完整对话流程 → 检查 trajectory_events 记录 → 验证压缩结果 → 检查异步写入无阻塞
