+3. 方法名遵循 `collect_{metric_name}()` 命名,返回 `list[dict]` 或 `dict`
+4. SQL 查询中使用 `INCLUDE PERFETTO MODULE {module_path};` 引入 stdlib
+5. 在 `PerfettoCollector` 中通过多重继承挂载 Mixin
+6. 查询结果按耗时/大小降序排列,使用 `LIMIT` 控制返回数量

+```
+
+构建脚本会自动完成以下步骤:
+
+1. Clone Perfetto 仓库(shallow clone)到 `perfetto-build/`
+2. 复制 SI Bridge 插件到 Perfetto 插件目录
+3. 在 `default_plugins.ts` 中注册插件
+4. 执行 `ui/build` 编译(含依赖安装、TypeScript 编译、WASM)
+
+构建产物输出到 `perfetto-build/ui/out/dist/`,可通过 `/open` 命令启动自托管 Perfetto UI。
+
+> **注意:** 脚本会自动移除 PATH 中的 Android NDK `strip` 以避免 macOS 上 Mach-O arm64 兼容性问题。如需代理,请提前设置 `http_proxy`/`https_proxy`。

+### P0 CpuBurnWorker 主线程执行CPU密集型计算导致卡顿
-### 问题列表(源码归因)
+**现象**:`CpuBurnWorker.startMainThreadWork$run` 在主线程执行耗时 145.00ms。该方法在主线程循环执行100,000次 `Math.sqrt` 计算,是导致主线程卡顿的直接原因。
-报告会通过 SI$ tag 将性能热点归因到具体源码位置,并给出优化建议:
+**原因**:根据源码归因,该方法是CPU烧录测试代码,在主线程上执行密集的数学运算,每次循环约5ms,每200ms执行一次,严重阻塞了主线程的UI渲染。
-```
-### P0 RecyclerView 布局与数据绑定严重卡顿
+**调用链**:`CpuBurnWorker.startMainThreadWork$run 145ms`
-现象:DemoAdapter.dispatchLayoutStep2 单次耗时 221.24ms,超出帧预算 15.5 倍。
-原因:onBindViewHolder 中存在 Thread.sleep、同步数据加载、主线程图片解码。
-位置:platform/android/app/.../DemoAdapter.java:40-64
+**位置**:`app/src/main/java/com/smartinspector/hook/worker/CpuBurnWorker.kt:41-49`
-建议:
-1. 移除 Thread.sleep(20ms)
-2. 将 loadItemsSync 改为异步加载
-3. 使用 Glide/Coil 异步图片加载
-4. 使用 DiffUtil 增量更新
-```
+**建议**:
+1. **移除或禁用测试代码**:在正式发布版本中,应移除或禁用此类用于测试的CPU烧录代码。
+2. **移至后台线程**:如果该逻辑是应用功能所需,必须将其移至后台线程(如使用 `CoroutineScope(Dispatchers.Default).launch` 或 `ExecutorService`)执行,避免阻塞主线程。
+3. **降低计算频率和强度**:如果必须在主线程执行,应大幅减少循环次数(例如从100,000次减少到1,000次以内)或延长执行间隔。
+
+### P0 DemoAdapter.onBindViewHolder 存在多项耗时操作导致列表滑动卡顿
+
+**现象**:`DemoAdapter.onBindViewHolder` 单次调用最高耗时 74.95ms,在测试期间共调用7次,累计耗时 202.29ms。该方法是导致帧#111严重卡顿(267.25ms)和 RecyclerView `dispatchLayoutStep2` 耗时 229.07ms 的主要原因。
+
+**原因**:根据源码归因,该方法内存在多个阻塞主线程的耗时操作:
+1. `doExpensiveWork()` 中调用了 `Thread.sleep(20)` 进行强制等待。
+2. `repository.loadItemsSync(5)` 进行同步数据加载。
+3. 执行了30次字符串拼接循环。
+4. 进行了 `Bitmap` 解码操作。
+
+**调用链**:`LinearLayoutManager.onLayoutChildren 228.97ms → RV OnBindView 75.05ms → DemoAdapter.onBindViewHolder 74.95ms`
+
+**位置**:`app/src/main/java/com/smartinspector/hook/adapter/DemoAdapter.java:40-64`
+
+**建议**:
+1. **移除 Thread.sleep**:在主线程中绝对禁止使用 `Thread.sleep()`,应立即移除。
+2. **异步加载数据**:将 `repository.loadItemsSync(5)` 改为异步加载(如使用 `LiveData`、`RxJava` 或 `Coroutine`),在数据准备好后再通知 `Adapter` 更新。
+3. **优化字符串构建**:使用 `StringBuilder` 替代多次 `+` 操作进行字符串拼接。
+4. **异步加载与缓存图片**:将 `Bitmap` 解码移至后台线程,并使用 `Glide`、`Picasso` 等图片加载库进行异步加载和缓存,避免每次绑定都解码。
+
+### P1 MainActivity.onCreate 中延迟任务过多且存在潜在风险
-完整报告示例见 [reports/perf_report_20260404_093038.md](reports/perf_report_20260404_093038.md)。
+**现象**:`MainActivity.onCreate` 耗时 14.67ms。方法中启动了多个 `Handler.postDelayed` 任务。
+
+**原因**:根据源码归因,方法中启动了多个延迟任务:1) 5秒后加载数据,2) 500ms间隔的循环padding调整,3) 8秒后显示详情Fragment。过多的延迟任务可能阻塞主线程,500ms的循环任务可能造成不必要的性能开销,且使用 `Handler.postDelayed` 有潜在的内存泄漏风险。
+
+**调用链**:`MainActivity.onCreate 14.67ms`
+
+**位置**:`app/src/main/java/com/smartinspector/hook/MainActivity.java:31-67`
+
+**建议**:
+1. **合并或优化任务**:评估500ms循环任务的必要性,考虑是否可以合并或由事件驱动(如监听视图状态)来触发。
+2. **使用 View.post**:对于需要在主线程执行的延迟UI操作,优先使用 `View.post()` 或 `View.postDelayed()`,这可以自动处理 `View` 生命周期,降低内存泄漏风险。
+3. **使用 Lifecycle-aware 组件**:对于需要在特定生命周期执行的任务,考虑使用 `Lifecycle` 和 `Coroutine` 等现代架构组件来管理。
+
+### P1 DemoAdapter.onCreateViewHolder 加载复杂布局耗时
+
+**现象**:`DemoAdapter.onCreateViewHolder` 单次调用最高耗时 4.89ms,在测试期间共调用7次,累计耗时 10.49ms。
+
+**原因**:根据源码归因,该方法加载了复杂布局 `item_complex`。布局的复杂度直接影响 `inflate` 和后续测量、布局的速度。
+
+**调用链**:`DemoAdapter.onCreateViewHolder 4.89ms`
+
+**位置**:`app/src/main/java/com/smartinspector/hook/adapter/DemoAdapter.java:33-37`
+
+**建议**:
+1. **检查并简化布局**:使用 Layout Inspector 或 `ConstraintLayout` 的布局优化工具,检查 `item_complex.xml` 的层级,减少不必要的嵌套。
+2. **使用 ViewStub**:对于列表中并非立即显示的复杂部分,可以考虑使用 `ViewStub` 进行延迟加载。
+3. **启用视图复用**:确保 `RecyclerView` 和 `Adapter` 正确设置了 `setHasStableIds(true)` 并实现了 `getItemId()`,以优化视图复用。
+
+### P1 item_complex.xml 布局嵌套过深导致inflate耗时
+
+**现象**:`item_complex.xml` 的 inflate 操作单次最高耗时 4.77ms,在测试期间共执行7次,累计耗时 9.80ms。
+
+**原因**:根据源码归因,该布局有4层嵌套,并且包含自定义视图 `HeavyDrawView`。深层级的嵌套会导致测量和布局过程计算量增大。
+
+**调用链**:`inflate#item_complex 4.77ms`
+
+**位置**:`app/src/main/res/layout/item_complex.xml:1-64`
+
+**建议**:
+1. **使用 ConstraintLayout 扁平化布局**:将根布局替换为 `ConstraintLayout`,利用其约束关系减少嵌套层级,目标是控制在2层以内。
+2. **优化 HeavyDrawView**:分析 `HeavyDrawView` 的 `onDraw` 方法,确保其绘制操作高效,避免在 `onDraw` 中分配对象或进行复杂计算。
+3. **使用 merge 标签**:如果该布局被 `include`,考虑在根节点使用 `` 标签以消除一层冗余的 `ViewGroup`。

+# Metric QA — 自然语言指标问答设计
+
+## 背景
+
+当前 SmartInspector 的分析模式是全量采集 + 全量分析(`/full`),用户无法针对单个指标追问。用户在跑完一次完整分析后,常需要针对具体指标做深入了解,例如"CPU 占用率怎么样?"、"内存有没有泄漏?"。
+
+本设计新增 `metric_qa` 节点,允许用户在已有 `perf_summary` 数据的基础上,用自然语言追问具体性能指标。
+
+## 约束
+
+- **前置条件**:用户必须先通过 `/full`、`/trace`、`/analyze` 等命令完成分析,`state["perf_summary"]` 中有数据。若无数据,提示用户先采集。
+- **触发场景**:仅在交互式 CLI 模式中使用,不涉及 headless/CI。
+- **指标范围**:固定 20 个预定义指标,不做开放问答。
+- **回答深度**:数据提取 + LLM 解读(包含优化建议)。
+
+## 指标定义
+
+### 指标映射表
+
+共 6 大类、20 个细粒度指标,每个指标映射到 `perf_summary` 中的数据段:
+
+#### 一、CPU & 调度类
+
+| ID | 指标名 | 中/英触发词 | perf_summary 数据段 |
+|---|---|---|---|
+| `cpu` | CPU 占用率 | cpu占用 / cpu usage / cpu使用率 | `cpu_usage.overall_cpu_pct` + `per_thread` |
+| `cpu_hotspot` | CPU 热点函数 | cpu热点 / hot function / 火焰图 | `cpu_hotspots[].function, samples, pct, callchain` |
+| `sched` | 线程调度 | 调度 / 上下文切换 / context switch | `scheduling.hot_threads` (switches, dominant_state) |
+| `blocked` | 主线程阻塞 | 阻塞 / 卡住 / block / ANR | `block_events[].dur_ms, stack_trace` |
+
+#### 二、内存类
+
+| ID | 指标名 | 中/英触发词 | perf_summary 数据段 |

+
+#### 三、UI & 渲染类
+
+| ID | 指标名 | 中/英触发词 | perf_summary 数据段 |
+|---|---|---|---|
+| `frame` | 帧率 / 卡顿 | 帧率 / fps / 卡顿 / jank / 掉帧 | `frame_timeline.fps, jank_frames, slowest_frames` |
+| `rv` | RecyclerView | 滚动 / recycler / list / 列表 | `view_slices.rv_instances[].methods, total_ms` |
+| `view` | View 绘制 | 绘制 / draw / measure / layout / view | `view_slices.slowest_slices` (measure/layout/draw) |
+| `compose` | Compose 重组 | compose / 重组 / recompose | `compose_slices.composables` (recompose_count, total_ms) |
+| `inflate` | 布局加载 | 布局加载 / inflate / 布局 | `view_slices` 中 `SI$inflate#` 前缀 slices |
+| `startup` | 冷启动 | 启动 / 冷启动 / startup / cold start | startup phases + bottlenecks |
+
+#### 四、IO 类
+
+| ID | 指标名 | 中/英触发词 | perf_summary 数据段 |
+|---|---|---|---|
+| `io` | IO 总览 | io / 磁盘 | `io_slices.summary` |
+| `network` | 网络请求 | 网络 / network / 请求 / okhttp | `io_slices` 中 `io_type: "network"` |
+| `db` | 数据库查询 | 数据库 / db / query / sql | `io_slices` 中 `io_type: "database"` |
+| `image` | 图片加载 | 图片 / image / glide / coil | `io_slices` 中 `io_type: "image"` |
+
+#### 五、线程 & 系统类
+
+| ID | 指标名 | 中/英触发词 | perf_summary 数据段 |
+|---|---|---|---|
+| `thread_state` | 线程状态分布 | 线程状态 / running / sleeping | `thread_state[].state_distribution` |

+
+#### 六、总览
+
+| ID | 指标名 | 中/英触发词 | perf_summary 数据段 |
+|---|---|---|---|
+| `overview` | 性能总览 | 性能怎么样 / overall / summary | 聚合所有关键指标 |
+
+## 架构设计
+
+### 流程
+
+```
+用户输入 "cpu占用率怎么样?"
+ → orchestrator 节点(LLM 意图分类)
+ → RouteDecision.metric_qa + metric_id="cpu"
+ → metric_qa 节点
+ 1. 检查 state["perf_summary"] 是否存在
+ 2. 根据 metric_id 提取对应数据段
+ 3. 调用 LLM 做专门解读(专用 prompt)
+ 4. 返回 messages + 解读结果
+```
+
+### RouteDecision 扩展
+
+在 `RouteDecision` 枚举中新增 `metric_qa` 值。orchestrator 路由到 `metric_qa` 节点。
+
+### AgentState 扩展
+
+无需新增 state 字段。metric_qa 节点通过 orchestrator 传递的 `_route` 值识别指标类型。
+
+具体来说,`_route` 的格式扩展为:
+- 原有:`"metric_qa"`
+- 新增约定:`"metric_qa:cpu"` — 冒号后跟 metric_id
+
+### 新增文件
+
+| 文件 | 说明 |
+|---|---|
+| `src/smartinspector/graph/nodes/metric_qa.py` | metric_qa 节点实现 |
+| `prompts/metric-qa.txt` | 指标解读 LLM prompt |
+
+### 修改文件
+
+| 文件 | 修改内容 |
+|---|---|
+| `src/smartinspector/graph/state.py` | RouteDecision 枚举新增 `metric_qa` |
+| `src/smartinspector/graph/nodes/orchestrator.py` | 意图分类 prompt 新增 metric_qa 路由 + metric_id 提取 |
+| `src/smartinspector/graph/__init__.py`(或 graph 构建文件) | 注册 metric_qa 节点 + 条件边 |
+
+## metric_qa 节点设计
+
+```python
+@node_error_handler("metric_qa")
+def metric_qa(state: AgentState) -> dict:
+ # 1. 解析 _route 获取 metric_id
+ route = state.get("_route", "")
+ metric_id = route.split(":")[1] if ":" in route else "overview"
+
+ # 2. 检查 perf_summary 是否存在
+ perf_summary = state.get("perf_summary", "")
+ if not perf_summary:
+ return {
+ "messages": [AIMessage(content="请先运行 /full 或 /trace 采集数据后再查询指标。")],
+ **_pass_through(state),
+ }
+
+ # 3. 提取对应指标数据
+ data = extract_metric_data(perf_summary, metric_id)
+
+ # 4. 调用 LLM 解读
+ metric_name = METRIC_NAMES.get(metric_id, "性能总览")
+ prompt = load_prompt("metric-qa").format(metric_name=metric_name, data=data)
+ result = llm.invoke(prompt)
+
+ # 5. 返回
+ return {
+ "messages": [result],
+ **_pass_through(state),
+ }
+```
+
+### extract_metric_data() 函数
+
+将 metric_id 映射到 perf_summary 的 JSON 路径,提取对应数据段。对于组合指标(如 `cpu` = `cpu_usage` + `cpu_hotspots`),合并多段数据。
+
+映射关系(metric_id → perf_summary keys):
+
+```python
+METRIC_DATA_MAP: dict[str, list[str]] = {
+ "cpu": ["cpu_usage"],
+ "cpu_hotspot": ["cpu_hotspots"],
+ "sched": ["scheduling"],
+ "blocked": ["block_events"],
+ "memory": ["process_memory"],
+ "heap": ["memory"],
+ "frame": ["frame_timeline"],
+ "rv": ["view_slices"], # 过滤 rv_instances
+ "view": ["view_slices"], # 过滤 slowest_slices
+ "compose": ["compose_slices"],
+ "inflate": ["view_slices"], # 过滤 SI$inflate# 前缀
+ "startup": [], # 来自 startup analyzer(单独数据段)
+ "io": ["io_slices"],
+ "network": ["io_slices"], # 过滤 io_type=network
+ "db": ["io_slices"], # 过滤 io_type=database
+ "image": ["io_slices"], # 过滤 io_type=image
+ "thread_state": ["thread_state"],
+ "sys": ["sys_stats"],
+ "input": ["input_events"],
+ "overview": [], # 聚合所有
+}
+```
+
+对于需要过滤的指标(`rv`、`view`、`inflate`、`network`、`db`、`image`),在提取后做二次过滤,只保留相关子集传给 LLM。
+
+## Orchestrator 意图分类扩展
+
+在现有路由 prompt 中新增 `metric_qa` 分类。示例 prompt 片段:
+
+```
+metric_qa — 用户追问某个具体性能指标。关键词:
+ cpu占用率、cpu usage、cpu热点、火焰图 → metric_qa:cpu_hotspot
+ 内存、memory、RSS → metric_qa:memory
+ 内存泄漏、heap、leak → metric_qa:heap
+ 帧率、fps、卡顿、jank、掉帧 → metric_qa:frame
+ 滚动、recycler、列表 → metric_qa:rv
+ 绘制、draw、measure、layout → metric_qa:view
+ compose、重组、recompose → metric_qa:compose
+ 布局加载、inflate → metric_qa:inflate
+ 网络、network、请求 → metric_qa:network
+ 数据库、db、query → metric_qa:db
+ 图片加载、glide、coil → metric_qa:image
+ 启动、冷启动、startup → metric_qa:startup
+ 阻塞、卡住、block、ANR → metric_qa:blocked
+ 线程状态、sleeping → metric_qa:thread_state
+ 性能怎么样、overall → metric_qa:overview
+ 调度、上下文切换 → metric_qa:sched
+ io、磁盘 → metric_qa:io
+ 系统状态、cpu频率 → metric_qa:sys
+ 触摸、touch → metric_qa:input
+```
+
+LLM 返回格式保持现有约定(单标签),只新增 `metric_qa:` 格式。
+
+## Prompt 设计
+
+`prompts/metric-qa.txt` 结构:
+
+```
+你是 Android 性能分析专家。用户正在查看一份 Perfetto trace 分析报告,针对「{metric_name}」指标追问。
+
+以下是该指标的原始数据:
+{data}
+
+请用中文回答用户的问题,要求:
+1. 先给出当前指标的数值概要(如"CPU 占用率 45%")
+2. 如果数据中有异常值,指出并解释
+3. 给出 1-2 条具体优化建议
+4. 如果用户问了具体问题,直接回答
+5. 控制在 200 字以内
+```
+
+## 错误处理
+
+| 场景 | 处理 |
+|---|---|
+| `perf_summary` 为空 | 返回提示:"请先运行 /full 或 /trace 采集数据" |
+| metric_id 对应的数据段为空 | 返回:"该 trace 中没有采集到 {metric_name} 相关数据" |
+| 无法识别具体指标 | fallback 到 `overview`(性能总览) |
+| startup 数据不在 perf_summary 中 | 从 state 中查找 startup 分析结果 |
+
+## 不做的事
+
+- 不做开放问答——只支持 20 个预定义指标
+- 不做自动采集——必须有已分析数据
+- 不改 headless/CI 模式——仅交互式 CLI
+- 不新增 AgentState 字段——复用 `_route` 传递 metric_id

+
+### 2.3 各模块质量评估
+
+| 模块 | 行数 | 评分 | 评价 |
+|------|------|------|------|
+| `graph/state.py` | 88 | 9/10 | 简洁的 AgentState 定义,`_pass_through` 和 `node_error_handler` 设计得当 |
+| `graph/builder.py` | 108 | 9/10 | 图构建清晰,路由映射完备,条件边设计合理 |
+| `agents/deterministic.py` | 822 | 9/10 | 纯计算层,与 LLM 职责分离明确,是架构亮点 |

+| `graph/nodes/orchestrator.py` | 263 | 8/10 | 路由逻辑完备,metric_qa 处理合理,但 prompt 内联过长 |
+| `graph/streaming.py` | 74 | 8/10 | 流式处理简洁,get_state() 复用得当 |
+| `config.py` | ~170 | 8/10 | 集中管理配置,支持环境变量覆盖,但有重复模式 |
+| `token_tracker.py` | ~80 | 9/10 | 线程安全,API 设计清晰 |
+| `collector/perfetto.py` | 2,345 | 6.5/10 | 功能完整但文件过大,存在 SQL 安全风险、静默异常吞没 |
+| `agents/attributor.py` | 1,027 | 7/10 | fast-path 优化到位,但 LLM 单例管理混乱 |
+| `commands/attribution.py` | 1,164 | 7/10 | SI$ tag 解析完备,但大量重复解析逻辑 |
+| `ws/bridge_server.py` | 436 | 6/10 | 全局可变状态过多,trace path 管理不够健壮 |

+| `storage/store.py` | ~200 | 7/10 | 基线管理功能完整,但与 reporter 耦合较紧 |
+
+### 2.4 做得好的地方(架构亮点)
+
+#### 1. Deterministic Pre-computation 层
+`agents/deterministic.py` 将算术和分类逻辑从 LLM 中完全剥离。`compute_hints()` 提供 8 个纯计算模块(severity、call_chain、RV hotspot、jank correlation、CPU hotspot、thread_state、SQL summarizer、perf JSON compression),大幅减少 LLM token 消耗,同时提高结论准确性。
+
+**这是项目最有价值的架构决策**,将"确定性计算"与"LLM 理解"清晰分离。
+
+#### 2. Attributor Fast-path
+`agents/attributor.py` 对简单 Java 类搜索走 Glob→Grep→Read 快路径,绕过 LLM 调用。Partial fallback 机制(部分命中 fast-path,其余走 LLM)设计精巧,兼顾效率和覆盖。
+
+#### 3. SI$ Tag System
+完整的 tag 解析体系(`commands/attribution.py`),涵盖 RV、block、inflate、view、handler、compose、net、db、img 等 12+ 种模式。匿名内部类处理尤其周到(`_extract_method_from_anonymous`)。
+
+#### 4. `node_error_handler` Decorator
+统一的节点错误处理模式,`@node_error_handler("node_name")` 确保任何节点异常不会导致 pipeline 崩溃,返回安全状态 + AIMessage 错误提示。
+
+#### 5. Pipeline Architecture Rule
+CLAUDE.md 中明确规定"所有新功能必须复用 LangGraph pipeline 链路",避免独立执行路径。这个约定保证了架构一致性。
+
+#### 6. Trace Collection Degradation
+PerfettoCollector 的 stdin-pipe → cat-pipe → cmdline 三级降级策略,覆盖 SELinux 限制等设备兼容性问题。
+
+### 2.5 核心数据流
+
+```
+用户输入 → orchestrator_node (LLM 路由)
+ │
+ ├─ full_analysis/startup → collector_node
+ │ │
+ │ └─ PerfettoCollector.summarize()
+ │ → 14 collect_*() 方法 → PerfSummary JSON
+ │ → perf_summary (str) 存入 AgentState
+ │
+ ├─ analyzer_node
+ │ │
+ │ └─ compute_hints(perf_json) ← 确定性预计算
+ │ └─ perf_analyzer agent (LLM) ← 生成分析
+ │ → perf_analysis (str) 存入 AgentState
+ │
+ ├─ attributor_node
+ │ │
+ │ └─ extract_attributable_slices(perf_json)
+ │ └─ fast-path: Glob→Grep→Read (无 LLM)
+ │ └─ slow-path: attributor agent (LLM + tools)
+ │ → attribution_result (str) 存入 AgentState
+ │
+ └─ reporter_node
+ │
+ └─ compute_hints(perf_json) ← 第二次计算(重复!)
+ └─ format_perf_sections(perf_json)
+ └─ LLM report generation (流式)
+ → Markdown/JSON 报告
+```
+
+---
+
+## 三、识别的核心问题
+
+### 3.1 P0 — 架构级问题(影响可维护性和扩展性)
+
+#### P0-1: `collector/perfetto.py` 巨型文件(2,345 行)
+
+**问题**: PerfettoCollector 单文件包含 14 个 `collect_*()` 方法,每个方法包含独立的 SQL 查询、数据转换和异常处理逻辑。文件行数是第二大文件(`commands/attribution.py` 1,164 行)的两倍。
+
+**影响**:
+- 代码审查困难,单个 PR 难以覆盖完整变更
+- 不同 collect 方法之间的公共逻辑(SQL 查询模板、结果转换)被复制
+- 无法独立测试单个 collect 方法(需 mock 整个 PerfettoCollector)
+
+**根因**: 缺少 collector 方法级别的模块化拆分。
+
+#### P0-2: AgentState 中 `perf_summary` 为 JSON 字符串
+
+**问题**: `perf_summary: str` 在 pipeline 内部以 JSON 字符串形式传递。每个消费节点(analyzer、attributor、reporter、metric_qa)都需要 `json.loads()` 解析,产生 3-4 次重复反序列化。
+
+**影响**:
+- 不必要的 CPU 消耗和内存分配
+- 类型不安全:消费方无法获得类型提示
+- `compute_hints()` 在 analyzer 和 reporter 阶段被调用两次(完全重复计算)
+
+**根因**: LangGraph 的 `TypedDict` state 要求可序列化类型,最初用 JSON string 是最简单方案,但缺乏演进。
+
+#### P0-3: LLM 实例管理碎片化
+
+**问题**: 6 个 Agent 模块各自维护独立的 LLM 单例,管理模式不一致:
+
+| 模块 | 模式 | 问题 |
+|------|------|------|
+| `orchestrator.py` | 全局 `_route_llm` | 被 reporter generator 不合理复用 |
+| `attributor.py` | 全局 + Lock + `_structured_ok` 探测 | 全局可变状态竞态风险 |
+| `perf_analyzer.py` | 全局 + Lock | 独立实例 |
+| `frame_analyzer.py` | 全局 + Lock | 独立实例 |
+| `explorer.py` | 全局 + Lock | 使用可能废弃的 `create_agent` API |
+| `android.py` | 全局 + Lock | 同上 |
+
+**影响**:
+- 修改 LLM 配置(如 temperature、model)需要改 6 个文件
+- Agent 实例化模式不一致(`bind_tools` + 手动 dispatch vs `create_agent` vs 单次 invoke)
+- 无法统一管理 token 配额和限流
+
+#### P0-4: 测试覆盖率极低(~9%)
+
+**问题**: 仅 4 个测试文件,1,208 行测试代码。核心业务逻辑(SI$ tag 解析、deterministic hints、SQL 查询、归因逻辑)缺乏测试保护。
+
+**影响**:
+- 重构风险极高:无法验证变更不引入回归
+- 架构改进难以落地:缺乏安全网
+- 关键业务逻辑(severity 分类、hotspot 排名)的正确性依赖人工验证
+
+### 3.2 P1 — 设计缺陷(影响代码质量和可靠性)
+
+#### P1-1: SI$ Tag 解析逻辑重复
+
+**问题**: `commands/attribution.py` (1,164 行) 中 `extract_class()`、`extract_method()`、`extract_fqn()` 三个函数对同一个 SI$ tag 分别独立解析,每个函数都有相同的 `if body.startswith("block#"):` 等分支结构,大量重复代码。
+
+**影响**: 修改 tag 格式(如新增 `SI$compose#`)需要在 3+ 个函数中同步修改,容易遗漏。
+
+#### P1-2: SQL 注入风险
+
+**问题**: `collector/perfetto.py` 多处 SQL 查询使用 f-string 拼接:
+- `WHERE name = '{package_name}'` (用户输入)
+- `WHERE uid = {uid}` (内部生成但未验证)
+- `WHERE id IN ({id_list})` (列表拼接)
+
+虽然 trace_processor 是本地进程,但 `package_name` 来自 CLI/WS 配置,理论上有注入可能。
+
+#### P1-3: `compute_hints()` 重复调用
+
+**问题**: `compute_hints(perf_json)` 在 pipeline 中被调用两次:
+1. `perf_analyzer.py` — analyzer 阶段
+2. `formatter.py` — reporter 阶段(通过 `format_perf_sections`)
+
+同一段 JSON 被解析和计算两次,完全浪费。
+
+#### P1-4: Bridge Server 全局状态管理
+
+**问题**: `bridge_server.py` 使用 4 个模块级全局变量管理状态:
+```python
+_active_bridge: BridgeServer | None = None
+_active_trace_server = None
+_cached_perf_summary: str = ""
+_cached_attribution_result: str = ""
+```
+
+变量命名不一致(`_perf_summary_cache` vs `_cached_perf_summary`),状态清理依赖调用方正确执行。
+
+#### P1-5: Agent API 不一致
+
+**问题**: 三种不同的 Agent 实现模式并存:
+1. `explorer.py` / `android.py` — `langchain.agents.create_agent`(可能已废弃)
+2. `attributor.py` — `llm.bind_tools` + 手动 tool dispatch
+3. `perf_analyzer.py` / `frame_analyzer.py` — 单次 `llm.invoke`
+
+增加新 Agent 时没有统一模式可参考。
+
+### 3.3 P2 — 优化项(影响性能和开发体验)
+
+#### P2-1: `perf_analyzer.py` 武断截断
+
+`perf_json[:3000]` 硬截断后发送给 LLM,可能截断关键数据(如 thread_state),也可能包含无用数据(如 cpu_idle_samples 时间序列)。
+
+#### P2-2: config.py 重复模式
+
+6 个 `get_*()` 函数完全同构(`try: return int(os.environ.get(...)) except: return default`),应提取为 `_env_int()` 辅助函数。
+
+#### P2-3: 函数内部 import
+
+`formatter.py` 在函数内部 `from smartinspector.agents.deterministic import compute_hints`,虽然 Python 缓存模块,但代码组织不规范。
+
+#### P2-4: perf_analyzer 智能截断
+
+应根据 `compute_hints` 结果智能选择补充数据,而非盲截。
+
+---
+
+## 四、功能架构改进方案
+
+### 4.1 改进一:Collector 模块化拆分
+
+**目标**: 将 2,345 行的 `perfetto.py` 拆分为模块化结构。
+
+**方案**:
+
+```
+collector/
+├── __init__.py
+├── perfetto.py # PerfettoCollector 基类(open/close/summarize 公共逻辑)
+├── sched.py # collect_sched(), collect_thread_state()
+├── cpu.py # collect_cpu_hotspots(), collect_cpu_usage()
+├── frame.py # collect_frame_timeline(), collect_view_slices()
+├── memory.py # collect_process_memory(), collect_memory() (已存在,整合)
+├── sys.py # collect_sys_stats(), collect_threads()
+├── io.py # collect_io_slices(), collect_input_events()
+├── block.py # collect_block_events()
+├── compose.py # collect_compose_slices()
+├── startup.py # StartupAnalyzer (已存在,保持)
+├── sql_utils.py # 公共 SQL 查询工具(参数化、批量查询、CTE 模板)
+└── types.py # PerfSummary dataclass, 公共类型定义
+```
+
+**关键设计**:
+- `PerfettoCollector` 保留为入口类,通过 Mixin 或组合模式组合各模块方法
+- 每个 `collect_*()` 方法可独立测试(只需 mock `TraceProcessor.query()`)
+- `sql_utils.py` 集中管理 SQL 模板,统一参数化查询
+
+**预期收益**:
+- 单文件代码量从 2,345 行降到 ~300 行(核心类) + 各子模块 100-200 行
+- 可独立测试每个 collect 方法
+- SQL 安全修复可集中在一个文件
+- 新增 collect 方法只需新建文件 + 注册到主类
+
+**实施复杂度**: 中等。主要是代码搬迁 + import 调整。
+
+**优先级**: P0
+
+---
+
+### 4.2 改进二:AgentState 数据类型优化
+
+**目标**: 消除 pipeline 内部 JSON 字符串的反复序列化/反序列化。
+
+**方案**:
+
+```python
+# graph/state.py
+class AgentState(TypedDict):
+ messages: Annotated[list, operator.add]
+ perf_summary_raw: dict # ← 内部传递 dict(替代 str)
+ perf_summary: str # ← 仅在边界序列化(LLM prompt 输入)
+ perf_hints: str # ← 新增:缓存 compute_hints 结果
+ perf_analysis: str
+ attribution_data: str
+ attribution_result: str
+ trace_duration_ms: int
+ trace_target_process: str
+ skip_wait: bool
+ _route: str
+ _trace_path: str
+```
+
+**迁移路径**:
+1. `collector_node` 中 `PerfettoCollector.summarize()` 返回 `dict`,同时生成 JSON string
+2. `perf_summary_raw` 存 dict,`perf_summary` 存 str(向后兼容)
+3. analyzer / attributor / reporter 优先读 `perf_summary_raw`
+4. `compute_hints()` 结果存入 `perf_hints`,reporter 直接复用
+
+**预期收益**:
+- 消除 3-4 次重复 `json.loads()` 调用
+- `compute_hints()` 只调用一次
+- 消费方获得类型提示
+- 对大 trace 文件(perf JSON > 100KB)性能提升明显
+
+**实施复杂度**: 中等。需要修改 state 定义和所有消费节点。
+
+**优先级**: P1
+
+---
+
+### 4.3 改进三:统一 LLM 实例管理(LLMFactory)
+
+**目标**: 集中管理所有 LLM 实例的创建和配置。
+
+**方案**:
+
+```python
+# llm_factory.py(新文件)
+import threading
+from langchain_openai import ChatOpenAI
+from smartinspector.config import get_llm_kwargs
+
+class LLMFactory:
+ """Centralized LLM instance management."""
+ _instances: dict[str, ChatOpenAI] = {}
+ _lock = threading.Lock()
+
+ @classmethod
+ def get(cls, role: str = "default", **overrides) -> ChatOpenAI:
+ """Get or create an LLM instance for the given role.
+
+ Args:
+ role: "default" | "attributor" | "router" | "streaming"
+ **overrides: Additional kwargs passed to ChatOpenAI
+ """
+ key = f"{role}:{frozenset(overrides.items())}"
+ if key not in cls._instances:
+ with cls._lock:
+ if key not in cls._instances:
+ kwargs = get_llm_kwargs(role=role if role != "default" else None)
+ kwargs.update(overrides)
+ cls._instances[key] = ChatOpenAI(**kwargs)
+ return cls._instances[key]
+
+ @classmethod
+ def get_with_tools(cls, role: str, tools: list, **overrides):
+ """Get LLM with bound tools."""
+ return cls.get(role, **overrides).bind_tools(tools)
+
+ @classmethod
+ def get_structured(cls, role: str, schema, **overrides):
+ """Get LLM with structured output."""
+ return cls.get(role, **overrides).with_structured_output(schema)
+
+ @classmethod
+ def reset(cls):
+ """Clear all instances (for testing)."""
+ with cls._lock:
+ cls._instances.clear()
+```
+
+**迁移路径**:
+1. 创建 `llm_factory.py`
+2. 逐个替换 6 个 Agent 的 LLM 初始化代码
+3. `attributor.py` 的 `_structured_ok` 探测逻辑改为初始化时一次性完成
+4. 统一 Agent 实现模式为 `bind_tools` + 手动 dispatch(attributor 的模式)
+
+**预期收益**:
+- LLM 配置变更只需改一处
+- 统一 temperature、max_tokens 等参数管理
+- Token 配额和限流可集中管理
+- 测试可轻松 mock LLM
+
+**实施复杂度**: 中低。逐个文件替换,无功能变更。
+
+**优先级**: P1
+
+---
+
+### 4.4 改进四:SI$ Tag 统一解析
+
+**目标**: 消除 `commands/attribution.py` 中的重复解析逻辑。
+
+**方案**:
+
+```python
+# commands/attribution.py
+from dataclasses import dataclass
+
+@dataclass
+class SITag:
+ """Structured representation of an SI$ tag."""
+ tag_type: str # "block", "RV", "inflate", "view", "handler", "compose", "net", "db", "img"
+ class_name: str # 短类名
+ method_name: str # 方法名
+ fqn: str # 完全限定名(可能为空)
+ search_type: str # "java", "xml", "system"
+ io_type: str | None # "network" | "database" | "image" | None
+ raw_name: str # 原始 tag
+ extras: dict # 额外字段(view_id, layout, duration 等)
+
+def parse_si_tag(name: str) -> SITag | None:
+ """Single-pass SI$ tag parser.
+
+ 替代 extract_class() + extract_method() + extract_fqn() 三次独立解析。
+ """
+ ... # 单次遍历,一次解析所有字段
+```
+
+**预期收益**:
+- 代码量从 ~1,164 行降至 ~400 行
+- 新增 tag 类型只需添加一个分支
+- 类型安全:消费方通过 `SITag` dataclass 获取字段
+- 可独立测试
+
+**实施复杂度**: 低。纯重构,无功能变更。
+
+**优先级**: P1
+
+---
+
+### 4.5 改进五:测试基础设施搭建
+
+**目标**: 建立核心模块的测试保护网,目标覆盖率 50%+。
+
+**方案(按优先级排序)**:
+
+| 优先级 | 模块 | 测试类型 | 理由 |
+|--------|------|----------|------|
+| P0 | `agents/deterministic.py` | 单元测试 | 纯函数,最容易测试,覆盖核心业务逻辑 |
+| P0 | `commands/attribution.py` (parse_si_tag) | 单元测试 | 纯函数,tag 解析是最核心的业务逻辑 |
+| P1 | `graph/state.py` (_pass_through, node_error_handler) | 单元测试 | 确保状态传递和错误处理正确 |
+| P1 | `agents/verifier.py` | 单元测试 | 确保验证逻辑正确 |
+| P1 | `graph/builder.py` | 集成测试 | 验证图构建和路由正确性 |
+| P2 | `collector/perfetto.py` (各 collect_*) | 单元测试 (mock SQL) | 需要 mock TraceProcessor |
+| P2 | `agents/attributor.py` (fast-path) | 单元测试 (mock tools) | 验证归因逻辑 |
+
+**测试基础设施**:
+- 使用 `pytest` + `pytest-mock`
+- 创建 `tests/conftest.py` 提供公共 fixture(mock TraceProcessor、sample perf JSON、sample SI$ tags)
+- CI 中运行 `pytest` 作为 gate check
+
+**预期收益**:
+- 重构和架构改进有安全网
+- 回归检测自动化
+- 新功能开发可先写测试
+
+**实施复杂度**: 低到中。纯函数测试容易,mock 测试需要设计 fixture。
+
+**优先级**: P0
+
+---
+
+### 4.6 改进六:扩展性改进 — 平台抽象层
+
+**目标**: 为 HarmonyOS / iOS 平台扩展建立清晰的架构基础。
+
+**当前问题**: 所有平台相关逻辑(adb、Perfetto、Android SDK hook)硬编码在 collector/ 和 agents/ 中。添加 HarmonyOS 支持(hdc、hitrace)需要在多处添加 if/else 分支。
+
+**方案**:
+
+```
+collector/
+├── base.py # BaseCollector 抽象基类
+│ └── abstract methods:
+│ ├── pull_trace() → str
+│ ├── get_target_process() → str
+│ └── get_device_info() → dict
+├── android/
+│ ├── perfetto.py # PerfettoCollector(BaseCollector)
+│ ├── sched.py
+│ ├── cpu.py
+│ └── ...
+├── harmonyos/
+│ ├── hitrace.py # HitraceCollector(BaseCollector)
+│ └── ...
+└── types.py # PerfSummary dataclass (平台无关)
+```
+
+**关键设计原则**:
+1. `BaseCollector` 定义标准采集接口和输出格式(`PerfSummary`)
+2. 平台特有逻辑封装在各自的 collector 子类中
+3. `PerfSummary` dataclass 是平台无关的中间表示
+4. 下游的 analyzer/attributor/reporter 不关心数据来自哪个平台
+
+**实施路径**: 长期演进,当前可在代码中预留接口(添加 TODO 标记),不急于实现。
+
+**优先级**: P2(长期演进方向)
+
+---
+
+### 4.7 改进七:Orchestrator 路由 Prompt 外置
+
+**目标**: 将 orchestrator 的路由 prompt 从 Python 代码内联移到 `prompts/` 目录。
+
+**当前问题**: `orchestrator.py` 中的 `_ROUTE_PROMPT`(65 行)和 `_FALLBACK_SYSTEM`(10 行)直接内联在 Python 代码中。按项目规则(CLAUDE.md "Prompt 管理规则"),超过 3 行的 prompt 必须抽取到 `prompts/` 目录。
+
+**方案**:
+- 创建 `prompts/route-classification.txt`
+- 创建 `prompts/fallback-system.txt`
+- `orchestrator.py` 中使用 `load_prompt("route-classification")` 加载
+
+**预期收益**:
+- 符合项目 Prompt 管理规则
+- 路由 prompt 可独立编辑和版本管理
+- A/B 测试不同路由策略时更方便
+
+**实施复杂度**: 极低。
+
+**优先级**: P2
+
+---
+
+## 五、实施路线图
+
+### Phase 1: 基础加固(建议立即开始)
+
+| # | 项目 | 涉及文件 | 预期收益 |
+|---|------|----------|----------|
+| 1 | 测试基础设施 + deterministic 测试 | 新建测试文件 | 重构安全网 |
+| 2 | SI$ Tag 统一解析 (parse_si_tag) | `commands/attribution.py` | 代码量减少 60%+ |
+| 3 | config.py 提取 `_env_int()` | `config.py` | 消除 6 个重复函数 |
+| 4 | Orchestrator prompt 外置 | `orchestrator.py` → `prompts/` | 符合项目规范 |
+| 5 | formatter.py 内部 import 移到顶部 | `formatter.py` | 代码规范 |
+
+### Phase 2: 架构改进(基础加固完成后)
+
+| # | 项目 | 涉及文件 | 预期收益 |
+|---|------|----------|----------|
+| 6 | LLMFactory 统一管理 | 新建 `llm_factory.py` + 6 个 Agent 文件 | 统一 LLM 实例管理 |
+| 7 | Collector 模块化拆分 | `collector/perfetto.py` → 10 个子模块 | 单文件从 2345 行降至 ~300 行 |
+| 8 | AgentState 数据类型优化 | `state.py` + 所有消费节点 | 消除重复 JSON 序列化 |
+| 9 | SQL 参数化查询 | `collector/sql_utils.py` | 消除 SQL 注入风险 |
+| 10 | compute_hints 缓存 | `state.py` + `perf_analyzer.py` + `formatter.py` | 消除重复计算 |
+
+### Phase 3: 扩展性建设(长期演进)
+
+| # | 项目 | 涉及文件 | 预期收益 |
+|---|------|----------|----------|
+| 11 | 平台抽象层(BaseCollector) | `collector/base.py` | 多平台扩展基础 |
+| 12 | Bridge Server 类封装 | `ws/bridge_server.py` | 消除全局状态 |
+| 13 | Agent API 统一(bind_tools) | `explorer.py` + `android.py` | 统一 Agent 模式 |
+| 14 | perf_analyzer 智能截断 | `agents/perf_analyzer.py` | LLM token 减少 30-50% |
+
+---
+
+## 六、风险与注意事项
+
+### 6.1 重构风险控制
+
+1. **先测试后重构**: Phase 2 的每项改进都应在 Phase 1 的测试基础上进行
+2. **增量变更**: 每个改进独立一个 commit,不混合多个改进
+3. **向后兼容**: AgentState 新增字段而非修改现有字段,确保现有功能不受影响
+4. **CI 验证**: 每次变更后运行 `uv run smartinspector --help` 验证入口正常
+
+### 6.2 架构约束
+
+1. **Pipeline Architecture Rule**: 所有新功能必须通过 LangGraph graph 执行
+2. **Logging Standard**: 禁止 `import logging`,统一使用 `info_log()` / `debug_log()`
+3. **Prompt 管理**: 超过 3 行的 prompt 必须外置到 `prompts/` 目录
+4. **文档同步**: 新增命令/功能必须同步更新 CLAUDE.md
+
+### 6.3 不建议做的事
+
+1. **不建议引入新的编排框架**: LangGraph 已经满足需求,引入新框架增加复杂度
+2. **不建议将 Collector 改为异步**: 当前同步模型简单可靠,异步改造收益不大
+3. **不建议过早抽象平台层**: 等 HarmonyOS 需求明确后再做,避免过度设计
+4. **不建议合并 Agent 和 Node 层**: 当前两层分离(Node 负责状态管理,Agent 负责业务逻辑)是合理的
+
+---
+
+## 七、总结
+
+AppSmartInspector 的核心架构(LangGraph pipeline + deterministic pre-computation + fast-path attribution)设计合理,是一个在"LLM 效率"和"分析准确性"之间取得良好平衡的系统。
+
+**最需要改进的三个领域**:
+1. **测试覆盖**(从 9% → 50%+):是所有其他改进的基础
+2. **Collector 模块化**(2,345 行 → 多模块):是可维护性的关键瓶颈
+3. **LLM 实例统一管理**(6 处碎片化 → LLMFactory):是扩展性的前提
+
+**最具价值的改进路径**: 先建立测试 → 再重构 Collector → 再统一 Agent 管理。这条路径确保每一步都有安全网,每一步都使代码更易于维护和扩展。

+
+## 1. 现状评估
+
+### 1.1 架构健康度总评分: 7.2 / 10
+
+项目整体架构设计合理,LangGraph pipeline 模式清晰,模块职责划分得当。deterministic pre-computation 层是一个亮点设计,有效减少了 LLM token 消耗。但在 SQL 查询性能、资源管理、错误处理一致性等方面存在改进空间。
+
+### 1.2 各模块质量评分
+
+| 模块 | 评分 | 说明 |
+|------|------|------|
+| `graph/state.py` | 9/10 | 简洁清晰的 AgentState 定义,`_pass_through` 和 `node_error_handler` 设计得当 |
+| `agents/deterministic.py` | 9/10 | 纯计算层设计优秀,与 LLM 职责分离明确 |
+| `graph/builder.py` | 9/10 | 图构建清晰,路由映射完备 |
+| `collector/perfetto.py` | 7/10 | 功能完整但有 SQL 注入风险、N+1 查询问题、资源管理不完善 |
+| `agents/attributor.py` | 7/10 | fast-path 优化到位,但 LLM 单例管理混乱,_structured_ok 全局可变状态 |
+| `graph/nodes/collector.py` | 8/10 | WS 集成良好,但缺少对 collector_node 的 `@node_error_handler` 装饰 |
+| `graph/nodes/reporter/` | 7/10 | 截断策略合理,但 formatter 和 generator 共享 LLM 实例设计不当 |
+| `commands/attribution.py` | 8/10 | SI$ tag 解析完备,匿名内部类处理周到 |
+| `ws/server.py` | 7/10 | 单例模式正确,但缺少重连/心跳超时后的自动恢复 |
+| `ws/bridge_server.py` | 6/10 | 全局可变状态过多,trace path 管理不够健壮 |
+| `config.py` | 8/10 | 简洁实用,env var 解析一致 |
+| `token_tracker.py` | 9/10 | 线程安全,API 设计清晰 |
+
+### 1.3 做得好的地方
+
+1. **Deterministic pre-computation** (`agents/deterministic.py`): 将算术和分类逻辑从 LLM 中剥离,大幅减少 token 消耗,同时提高了结论的准确性。这是一个非常值得肯定的架构决策。
+
+2. **Attributor fast-path** (`agents/attributor.py:137-327`): 对于简单的 Java 类搜索,绕过 LLM 直接执行 Glob→Grep→Read,既节省 token 又提高速度。partial fallback 机制(部分命中 fast-path,其余走 LLM)设计精巧。
+
+3. **`node_error_handler` decorator** (`graph/state.py:62-84`): 统一的节点错误处理模式,避免任何单个节点的异常导致整个 pipeline 崩溃。
+
+4. **SI$ tag system**: 完整的 tag 解析体系(`commands/attribution.py`),涵盖 RV、block、inflate、view、handler 等多种模式,匿名内部类的处理尤其周到。
+
+5. **Trace collection degradation** (`collector/perfetto.py:1750-1831`): stdin-pipe → cat-pipe → cmdline 三级降级策略,覆盖了 SELinux 限制等设备兼容性问题。
+
+6. **LRU file cache** (`agents/attributor.py:63-98`): 跨 group 共享的文件缓存,避免 attributor 多轮迭代中重复读取相同文件。
+
+### 1.4 关键技术债务清单

+**问题描述**: `collect_thread_state()` 在 `__intrinsic_thread_state` 主路径中,对每个 slice 单独执行一次 SQL 查询(per-slice loop, `collector/perfetto.py:1264-1278`),且每次还需要额外查询 waker name(`collector/perfetto.py:1317-1324`)。20 个 slice 最多产生 20 + 20 = 40 次 SQL 查询。
+
+**影响范围**: `collector/perfetto.py:1203-1338`
+
+**具体方案**:
+
+1. 将 per-slice 查询改为批量 CTE 查询,一次 SQL 获取所有 slice 的 thread_state 分布:
+
+```sql
+WITH slices AS (
+ SELECT name, ts, dur, ts + dur AS end_ts
+ FROM slice
+ WHERE name LIKE 'SI$%' AND dur > 1000000
+ ORDER BY dur DESC LIMIT 20
+)
+SELECT
+ s.name AS slice_name,
+ its.state,
+ SUM(its.dur) AS total_ns,
+ its.blocked_function,
+ its.io_wait,
+ its.waker_utid
+FROM slices s
+JOIN __intrinsic_thread_state its
+ ON its.utid = :main_utid
+ AND its.ts < s.end_ts
+ AND its.ts + its.dur > s.ts
+GROUP BY s.name, its.state, its.blocked_function, its.io_wait, its.waker_utid
+ORDER BY s.name, total_ns DESC
+```
+
+2. waker name 批量解析:收集所有 unique `waker_utid`,一次查询获取所有 name。
+
+**预估收益**: SQL 查询次数从 ~40 降低到 2(主查询 + waker 批量查询),thread_state 分析耗时减少 80%+。
+
+**实施复杂度**: 中等。需要重构 Python 端的结果聚合逻辑。
+
+### P2-2: `_walk_call_chain` 的逐行查询
+
+**问题描述**: `perfetto.py:2104-2133` 中的 `_walk_call_chain` 对每个 parent_id 单独执行 SQL 查询,最深 20 层。在 `query_frame_slices` 中最多 10 个 slice 调用,总计可能 200 次 SQL 查询。
+
+**影响范围**: `collector/perfetto.py:2104-2133`
+
+**具体方案**: 预加载所有相关 slice 到内存 map,然后在 Python 中遍历 parent 链(与 `collect_view_slices` 中 `_build_chain` 的做法一致)。
+
+```python
+def _walk_call_chain_cached(tp, slice_id: int, slice_map: dict, seen: set) -> dict:
+ """Walk call chain using pre-loaded slice map."""
+ chain_items = []
+ current_id = slice_id
+ for _ in range(20):
+ if current_id is None or current_id in seen or current_id not in slice_map:
+ break
+ r = slice_map[current_id]
+ seen.add(current_id)
+ chain_items.append({...})
+ current_id = r.get("parent_id")
+ ...
+```
+
+在 `query_frame_slices` 中,先一次性查询所有涉及的 slice(按 parent_id 递归),构建 map,然后遍历。
+
+**预估收益**: `query_frame_slices` 中 SQL 查询从 ~200 降低到 ~5。
+
+**实施复杂度**: 低。
+
+### P2-3: PerfSummary.to_json() 的重复 JSON 序列化
+
+**问题描述**: `PerfSummary.to_json()` 使用 `json.dumps(self.__dict__, indent=2)`。随后在 `collector_node` 中,这个 JSON 字符串又在 `formatter.py` 中被 `json.loads()` 解析,又被 `deterministic.py` 中的 `compute_hints` 再次 `json.loads()`。同一段数据被反复序列化/反序列化 3-4 次。
+
+**影响范围**: `collector/perfetto.py:80-81`, `graph/nodes/reporter/__init__.py`, `graph/nodes/reporter/formatter.py`, `agents/deterministic.py`
+
+**具体方案**: 在 pipeline 内部传递 `dict` 而非 JSON 字符串,仅在边界(state 存储和 LLM prompt 输入)进行 JSON 序列化。
+
+- `PerfettoCollector.summarize()` 返回 `dict` 而非调用 `to_json()`
+- `collector_node` 存储到 state 时序列化一次
+- `formatter.py` 和 `deterministic.py` 直接接收 `dict`
+
+**预估收益**: 减少不必要的 CPU 消耗和内存分配,对大 trace 尤为明显。
+
+**实施复杂度**: 中等。需要修改 state 中 `perf_summary` 的类型约定。
+
+### P2-4: LLM token 效率 - perf_analyzer 截断策略
+
+**问题描述**: `perf_analyzer.py:49` 将 `perf_json[:3000]` 截断后发送给 LLM,但 `compute_hints` 已经预计算了所有结论。原始 JSON 仅作为"参考"出现,3000 字符的限制过于武断,可能截断关键数据(如 thread_state),也可能包含大量无用数据(如 cpu_idle_samples 的时间序列)。
+
+**影响范围**: `agents/perf_analyzer.py:46-49`
+
+**具体方案**: 根据 `hints` 的内容智能选择补充数据,而非盲截。例如:
+- 如果 `_classify_severity` 输出非空,附上 view_slices 的 slowest_slices
+- 如果 `_analyze_thread_state` 输出非空,附上 thread_state 完整数据
+- 始终附上 frame_timeline 汇总(FPS, jank count)
+
+**预估收益**: LLM 输入 token 减少 30-50%(去掉无用的时间序列数据),同时分析质量提升(保留关键数据)。
+
+**实施复杂度**: 低。
+
+### P2-5: reporter 重复调用 compute_hints
+
+**问题描述**: `compute_hints(perf_json)` 在 pipeline 中被调用两次:
+1. `perf_analyzer.py:43` — analyzer 阶段
+2. `formatter.py:17` — reporter 阶段(通过 `format_perf_sections`)
+
+同一段 JSON 被解析和计算两次,完全浪费。
+
+**影响范围**: `agents/perf_analyzer.py:43`, `graph/nodes/reporter/formatter.py:17`
+
+**具体方案**: 将第一次 `compute_hints` 的结果存入 state(新增 `perf_hints` 字段),reporter 直接复用。
+
+**预估收益**: 避免重复 JSON 解析 + 6 个分析函数的重复计算。
+
+**实施复杂度**: 低。
+
+---
+
+## 3. 架构改进建议
+
+### A1: SQL 注入风险修复
+
+**当前问题**: 多处 SQL 查询使用 f-string 拼接用户可控输入:
+
+- `collector/perfetto.py:130`: `WHERE name = '{package_name}'`
+- `collector/perfetto.py:149-153`: `WHERE package_name = '{package_name}'`
+- `collector/perfetto.py:166`: `WHERE uid = {uid}`
+- `collector/perfetto.py:743`: `WHERE id IN ({id_list})`
+- `collector/perfetto.py:965-971`: track_id IN 查询
+- `collector/perfetto.py:1183-1199`: thread_state 多处 f-string
+
+虽然 Perfetto trace_processor 是本地进程且数据来自设备 trace,不涉及网络攻击面,但 `package_name` 和 `target_process` 来自 CLI 输入/WS 配置,理论上有注入可能。
+
+**目标架构**: 使用参数化查询或至少进行输入验证。
+
+**迁移路径**:
+1. 在 `PerfettoCollector.__init__` 中验证 `target_process` 格式(仅允许 `[a-zA-Z0-9._]`)
+2. 对于 `id_list` 类查询,确保所有 ID 都是整数(`int()` 转换)
+3. 对于 `utid` 等,已在内部生成,风险较低,但仍建议使用占位符
+
+**风险评估**: 低风险修改,不影响功能。
+
+### A2: TraceProcessor 资源管理
+
+**当前问题**: `query_frame_slices()` (`collector/perfetto.py:1934-2039`) 创建了 `TraceProcessor` 实例并在 `finally` 中 close,这是正确的。但 `PerfettoCollector` 的 `_open()` 方法只在 `close()` 中释放,而 `summarize()` 调用链中如果中途异常,`_tp` 可能不会被关闭。
+
+更重要的是,`PerfettoCollector` 用作 context manager 时如果 `summarize()` 抛异常(如 `collect_cpu_hotspots` 失败),`__exit__` 能正确清理。但在 `collector_node` 中(`graph/nodes/collector.py:184`):
+
+```python
+collector = PerfettoCollector(trace_path, target_process=target_process)
+summary = collector.summarize()
+```
+
+没有使用 `with` 语句,`close()` 从未被调用。这意味着 `trace_processor_shell` 子进程在 `summarize()` 完成后仍然运行。
+
+**目标架构**: 使用 context manager 确保资源释放。
+
+**迁移路径**:
+```python
+with PerfettoCollector(trace_path, target_process=target_process) as collector:
+ summary = collector.summarize()
+```
+
+**风险评估**: 安全修改,`summarize()` 内部的 try/except 已保证即使异常也有结果返回。
+
+### A3: 统一 LLM 实例管理
+
+**当前问题**: LLM 实例分散在多处,管理模式不一致:
+
+| 位置 | 模式 | 问题 |
+|------|------|------|
+| `orchestrator.py:39-47` | 全局 `_route_llm` | 单例,但被 reporter 的 `generate_report` 复用(不合理) |
+| `attributor.py:100-130` | 全局 + Lock + 探测 | `_structured_ok` 全局变量,线程不安全 |
+| `perf_analyzer.py:17-25` | 全局 + Lock | 独立实例 |
+| `frame_analyzer.py:21-29` | 全局 + Lock | 独立实例 |
+| `explorer.py:19-33` | 全局 + Lock | `create_agent` API(可能已废弃) |
+| `android.py:16-31` | 全局 + Lock | 同上 |
+
+**目标架构**: 创建 `LLMFactory` 类集中管理 LLM 实例。
+
+```python
+# config.py 或新的 llm_factory.py
+class LLMFactory:
+ _instances: dict[str, ChatOpenAI] = {}
+ _lock = threading.Lock()
+
+ @classmethod
+ def get(cls, role: str = "default", **kwargs) -> ChatOpenAI:
+ key = f"{role}:{frozenset(kwargs.items())}"
+ if key not in cls._instances:
+ with cls._lock:
+ if key not in cls._instances:
+ cls._instances[key] = ChatOpenAI(**get_llm_kwargs(role=role, **kwargs))
+ return cls._instances[key]
+```
+
+**迁移路径**: 逐个替换现有全局变量。注意 `attributor.py` 的 `_structured_ok` 探测逻辑需要特殊处理。
+
+**风险评估**: 低风险,但需要测试各 LLM 实例的 temperature/max_tokens 配置是否保持一致。
+
+### A4: agent 层 API 不一致
+
+**当前问题**:
+- `explorer.py:36` 和 `android.py:16` 使用 `langchain.agents.create_agent` — 这个 API 在 LangChain 中可能已废弃或不存在于当前版本
+- `attributor.py` 使用手动的 tool-call loop(`llm.bind_tools` + 手动 dispatch)
+- `perf_analyzer.py` 和 `frame_analyzer.py` 使用单次 `llm.invoke`
+
+三种不同的 agent 实现模式增加了维护负担。
+
+**目标架构**: 统一使用 `llm.bind_tools` + 手动 dispatch 模式(attributor 的模式已被验证最可控),或统一使用 LangGraph 的 `create_react_agent`。
+
+**迁移路径**: 长期演进。当前优先修复 `create_agent` 的导入问题。
+
+**风险评估**: 中等。需要验证 LangChain 版本兼容性。
+
+### A5: 缺少 `@node_error_handler` 的节点
+
+**当前问题**: 以下节点缺少 `@node_error_handler` 装饰:
+
+- `graph/nodes/collector.py:107` — `collector_node`: 内部有 try/except 但不返回 `_pass_through` 字段,可能导致下游节点读到空值
+- `graph/nodes/attributor.py:33` — `attributor_node`: 完全没有异常处理
+- `graph/nodes/reporter/__init__.py:21` — `reporter_node`: 完全没有异常处理
+
+这意味着如果这些节点抛出未预期的异常,LangGraph 会直接终止整个 pipeline,用户看到的是原始 traceback 而非友好错误信息。
+
+**目标架构**: 所有 graph node 使用 `@node_error_handler` 装饰。
+
+**迁移路径**: 逐个添加装饰器,确保每个节点的异常都被捕获并转换为 AIMessage。
+
+**风险评估**: 低风险。
+
+### A6: bridge_server 全局状态管理
+
+**当前问题**: `bridge_server.py:314-317` 使用模块级全局变量管理状态:
+
+```python
+_active_bridge: BridgeServer | None = None
+_active_trace_server = None
+_cached_perf_summary: str = ""
+_cached_attribution_result: str = ""
+```
+
+`start_bridge()` 中还局部变量覆盖了这些全局(`_perf_summary_cache` vs `_cached_perf_summary`),容易混淆。
+
+**目标架构**: 将状态封装到 `BridgeManager` 类中,或至少统一变量命名。
+
+**迁移路径**: 短期:统一变量命名。长期:封装到类。
+
+**风险评估**: 低风险。
+
+---
+
+## 4. 可靠性改进
+
+### R1: TraceProcessor 连接超时处理
+
+**问题**: `PerfettoCollector._open()` (`collector/perfetto.py:100-108`) 设置了 `load_timeout=10` 秒,但没有重试机制。对于大 trace 文件(>100MB),首次加载可能超时。
+
+**方案**: 添加重试逻辑,或根据文件大小动态调整超时。
+
+```python
+def _open(self) -> TraceProcessor:
+ if self._tp is not None:
+ return self._tp
+ file_size_mb = Path(self.trace_path).stat().st_size / 1024 / 1024
+ timeout = max(10, int(file_size_mb / 10)) # 100MB -> 10s, 1GB -> 100s
+ config = TraceProcessorConfig(bin_path=self.shell_path, load_timeout=timeout)
+ self._tp = TraceProcessor(trace=self.trace_path, config=config)
+ return self._tp
+```
+
+**文件**: `collector/perfetto.py:100-108`
+
+### R2: WS 连接断开后的状态同步
+
+**问题**: `ws/server.py:278-283` 的 `_handler` 在连接关闭时从 `_connections` 中移除,但没有清理 `_pending_acks`。如果 app 在 ACK 到达前断开,等待 ACK 的线程会永久阻塞直到 timeout。
+
+**方案**: 在连接关闭时,set 所有 pending acks(标记为失败)。
+
+```python
+async def _handler(self, ws) -> None:
+ self._connections.add(ws)
+ try:
+ async for raw in ws:
+ ...
+ except websockets.exceptions.ConnectionClosed:
+ pass
+ finally:
+ self._connections.discard(ws)
+ # Release any pending ACKs for this connection
+ for msg_id, event in list(self._pending_acks.items()):
+ if not event.is_set():
+ event.set() # Will return False from send_config/send_start_trace
+```
+
+**文件**: `ws/server.py:264-283`
+
+### R3: attributor 的 `_structured_ok` 竞态条件
+
+**问题**: `attributor.py:55` 的 `_structured_ok` 是模块级全局变量,在 `_get_llm()` 中初始化,在 `_search_group()` 中修改为 `False`。如果有两个 attributor 调用并发执行(虽然当前 CLI 是单线程),一个修改 `_structured_ok` 可能影响另一个。
+
+**当前风险评估**: 低。CLI 是单线程调用 attributor,但 frame_analyzer 的 bridge_server 调用在 executor 线程中,理论上可能并发。
+
+**方案**: 将 `_structured_ok` 移入 `_get_llm()` 的 Lock 保护范围内,或在初始化时一次性探测并缓存。
+
+**文件**: `agents/attributor.py:55, 863`
+
+### R4: subprocess 资源泄漏
+
+**问题**: `TraceServer` (`collector/perfetto.py:1877`) 使用 `Popen` 启动 `trace_processor_shell`,如果 BridgeServer 异常退出,`TraceServer.stop()` 可能不被调用。`bridge_server.py:419-427` 的 `stop_bridge()` 虽然会清理,但依赖调用方正确调用。
+
+**方案**: 为 `TraceServer` 添加 `__del__` 方法作为最后保障,或使用 `atexit` 注册清理。
+
+```python
+import atexit
+
+class TraceServer:
+ def __init__(self, ...):
+ atexit.register(self.stop)
+```
+
+**文件**: `collector/perfetto.py:1848-1919`
+
+### R5: JSON 解析失败的静默吞没
+
+**问题**: 多处 `json.loads()` 在 try/except 中静默吞没错误,返回空值:
+
+- `perf_analyzer.py:46`: `compute_hints` 内 `json.loads` 失败返回 `""`
+- `formatter.py:22`: `json.loads` 失败返回 `{}`
+- `frame_analyzer.py:79`: `json.loads` 失败截断到前 2000 字符
+
+这些静默失败可能隐藏重要错误,使得调试困难。
+
+**方案**: 至少用 `logger.warning` 记录解析失败,不要完全静默。
+
+**文件**: 多处
+
+### R6: node_error_handler 中的 print
+
+**问题**: `graph/state.py:78` 的 `node_error_handler` 使用 `print()` 输出错误信息,而非 `logger.error()`。按照项目的 logging 标准,应该使用 logger。
+
+```python
+# 当前
+print(f" [{node_name}] ERROR: {e}", flush=True)
+
+# 应改为
+import logging
+logging.getLogger(__name__).error("[%s] %s", node_name, e)
+```
+
+**文件**: `graph/state.py:78`
+
+---
+
+## 5. 代码质量改进
+
+### Q1: extract_class / extract_method 的重复解析模式
+
+**问题**: `commands/attribution.py` 中 `extract_class()`, `extract_method()`, `extract_fqn()` 三个函数对同一个 SI$ tag 分别解析一次,且解析逻辑高度重复(每個函数都有相同的 `if body.startswith("block#"):` 等分支)。
+
+**方案**: 创建统一的 `_parse_si_tag()` 函数,一次解析返回结构化结果:
+
+```python
+@dataclass
+class SITag:
+ tag_type: str # "block", "RV", "inflate", "view", "handler", ...
+ class_name: str
+ method_name: str
+ fqn: str
+ search_type: str # "java", "xml", "system"
+ raw_name: str
+
+def parse_si_tag(name: str) -> SITag:
+ """Single-pass SI$ tag parser."""
+ ...
+```
+
+**文件**: `commands/attribution.py:15-401`
+
+### Q2: formatter.py 中 import 放在函数内部
+
+**问题**: `graph/nodes/reporter/formatter.py:17` 在函数内部 `from smartinspector.agents.deterministic import compute_hints`,每次调用都执行 import 查找(虽然 Python 会缓存)。
+
+**方案**: 移到文件顶部。如果存在循环依赖问题,说明模块拆分不合理。
+
+**文件**: `graph/nodes/reporter/formatter.py:17`, `agents/perf_analyzer.py:42`
+
+### Q3: SIServer 单例模式的可测试性
+
+**问题**: `ws/server.py` 的 `SIServer` 使用类级 `_instance` 和 `_lock` 实现单例。这使得单元测试难以注入 mock server。
+
+**方案**: 添加 `reset()` 类方法用于测试,或使用依赖注入。
+
+**文件**: `ws/server.py:58-63`
+
+### Q4: 测试覆盖
+
+**问题**: 项目目前没有测试文件(`tests/` 目录为空或不存在)。
+
+**建议的测试优先级**:
+
+1. **P0**: `commands/attribution.py` 的 SI$ tag 解析 — 纯函数,容易测试,覆盖最核心的业务逻辑
+2. **P0**: `agents/deterministic.py` 的 `compute_hints` — 纯函数,验证预计算逻辑正确性
+3. **P1**: `collector/perfetto.py` 的 SQL 查询逻辑(用 mock TraceProcessor)
+4. **P1**: `graph/state.py` 的 `_pass_through` 和 `node_error_handler`
+5. **P2**: 各 graph node 的输入/输出契约
+
+### Q5: 代码重复 — block stack trace 关联
+
+**问题**: `collect_block_events()` (`collector/perfetto.py:1169-1201`) 和 `_correlate_block_stacks_from_logcat()` (`collector/perfetto.py:2042-2101`) 实现了几乎相同的 bisect-based 时间戳关联逻辑。
+
+**方案**: 提取公共函数 `_correlate_by_timestamp(sql_events, log_entries, match_window_ns)`。
+
+**文件**: `collector/perfetto.py:1169-1201` 和 `collector/perfetto.py:2042-2101`
+
+### Q6: config.py 的 get_* 函数重复模式
+
+**问题**: `config.py` 中 `get_tool_timeout()`, `get_read_max_lines()`, `get_read_max_bytes()`, `get_read_max_line_length()`, `get_report_max_tokens()`, `get_ws_ping_timeout()` 六个函数完全同构:
+
+```python
+def get_xxx() -> int:
+ try:
+ return int(os.environ.get("SI_XXX", default))
+ except (ValueError, TypeError):
+ return default
+```
+
+**方案**: 提取 `_env_int(key, default)` 辅助函数。
+
+```python
+def _env_int(key: str, default: int) -> int:
+ try:
+ return int(os.environ.get(key, str(default)))
+ except (ValueError, TypeError):
+ return default
+
+def get_tool_timeout() -> int:
+ return _env_int("SI_TOOL_TIMEOUT", 30)
+```
+
+**文件**: `config.py:122-170`

+# Bug Fixes — 日志规范、Startup包名、Trace复用
+
+## Bug 1: print() 替换为 logger
+
+**问题**: 代码中大量使用 `print()` 输出 info/warning 信息到终端,应该统一使用 `logging.getLogger(__name__)` 的 `logger.info()` / `logger.warning()`。
+
+**规则(已在 CLAUDE.md 中加粗强调)**:
+- 所有 info/warning 级别的日志必须使用 `logger.info()` / `logger.warning()`,禁止 `print()`
+- `print()` 仅允许用于用户面向的交互式输出(CLI 提示、进度条、表格等),即用户在终端里需要看到的内容
+- debug 日志使用 `debug_log(category, message)`
+- error 日志使用 `logger.error()`
+
+**需要修改的文件**:
+- `src/smartinspector/graph/cli.py` — print(f" Warning: ...") → logger.warning()
+- `src/smartinspector/commands/trace.py` — print(f" Warning: ...") → logger.warning()
+- `src/smartinspector/commands/hook.py` — print(f" Warning: ...") → logger.warning()
+- `src/smartinspector/ws/bridge_server.py` — print(" [bridge] WARNING: ...") → logger.warning()
+- 其他所有文件中 print() 输出 info/warning 的地方
+
+**注意**: 不要改用户面向的进度输出(如 "正在采集..."、"分析完成" 等),这些保留 print()。
+
+## Bug 2: Startup 分析不支持包名传递 + adb am start 后 trace 报错
+
+**问题**:
+1. 自然语言说"分析冷启动"或"冷启动耗时"时,如果没有指定包名,collector 会跳过自动 adb launch
+2. adb am start 在 Perfetto trace 期间执行时,可能导致 pipe IO close 错误
+
+**修复**:
+1. 在 orchestrator 检测到 startup 意图时,从 `state["trace_target_process"]` 或 `perfetto_config` 读取包名。如果都没有,提示用户通过 `/config target_process com.xxx.xxx` 设置包名
+2. 确保 `_adb_launch_app()` 在 Perfetto 的 `on_record_start` 回调中执行,且不阻塞 trace 进程。检查是否有子进程竞争或 pipe 问题
+
+**涉及文件**:
+- `src/smartinspector/graph/nodes/orchestrator.py` — startup 路由时检查包名
+- `src/smartinspector/graph/nodes/collector.py` — on_record_start 回调的 pipe 问题
+- `src/smartinspector/collector/perfetto.py` — pull_trace_from_device 的 on_record_start 执行时机
+
+## Bug 3: /full 命令和自然语言全量分析复用上次 trace
+
+**问题**: collector 节点在 state 中保存 `_trace_path`,下次执行 full 时如果 state 中的 `_trace_path` 指向的文件仍然存在,`preloaded_trace` 检测会复用旧 trace 文件,跳过设备采集。
+
+**修复**: collector 节点开头清空 state 中的旧数据:
+```python
+# 清空上次分析数据,强制重新采集
+return_values = {
+ "perf_summary": "",
+ "perf_analysis": "",
+ "attribution_data": "",
+ "attribution_result": "",
+ "_trace_path": "",
+}
+```
+
+**注意**: 清空 `_trace_path` 就够了,因为 `preloaded_trace` 检查依赖它。不需要清空用户消息历史。
+
+**涉及文件**:
+- `src/smartinspector/graph/nodes/collector.py` — collector_node 开头

+# SI 归因系统改进方案:调用栈精确归因
+
+## 1. 现状分析
+
+### 1.1 当前归因流程
+
+```
+Perfetto trace (.pb)
+ ↓ collector/perfetto.py :: collect_view_slices()
+ ↓ SQL 查询 slice 表,获取 id/name/ts/dur/depth/parent_id
+view_slices JSON
+ ↓ commands/attribution.py :: extract_attributable_slices()
+ ↓ 提取 SI$ 前缀 → 解析 class_name + method_name
+attributable 列表 [{class_name, method_name, dur_ms, ...}]
+ ↓ agents/attributor.py :: run_attribution() → _search_group()
+ ↓ LLM 调用 Glob → Grep → Read 工具
+源码归因结果 [{file_path, line_start, line_end, source_snippet}]
+```
+
+### 1.2 关键缺陷
+
+**问题一:调用点歧义**
+
+当一个方法(如 `Adapter.onBindViewHolder`)在多个文件中被调用,或同一文件中多处调用时:
+- 系统只能定位方法定义位置,无法确定是**哪次调用**导致性能问题
+- 归因会列出所有匹配位置,LLM 需要猜测哪个是热点
+- 多余的搜索结果浪费 token
+
+**问题二:上下文缺失**
+
+LLM 搜索 `Adapter.onBindViewHolder` 时不知道:
+- 这个调用发生在哪个 Activity/Fragment 的上下文中
+- 是哪个 RecyclerView 实例触发的(如果有多个 RV)
+- 在 doFrame 的哪个子阶段(measure/layout/draw)
+
+**问题三:数据已采集但未利用**
+
+`collector/perfetto.py` 的 `collect_view_slices()` 已经:
+- 查询了每个 slice 的 `parent_id`(第 607 行)
+- 构建了 `children_map` 父子关系映射(第 759-765 行)
+- 构建了 `call_chains` 调用链(第 805-821 行)
+- 甚至向上回溯了祖父节点(第 650-664 行)
+
+但 `extract_attributable_slices()` 完全没有使用这些调用栈信息。
+
+### 1.3 当前数据流中的信息断裂点
+
+| 数据阶段 | 调用栈信息 | 是否传递给下游 |
+|----------|-----------|---------------|
+| `collect_view_slices()` SQL 查询 | `parent_id` 已获取 | ✅ 存入 slice dict |
+| `collect_view_slices()` 调用链构建 | `call_chains` 已构建 | ✅ 写入 view_slices JSON |
+| `extract_attributable_slices()` | **未读取** `call_chains` | ❌ 断裂点 |
+| `_build_group_prompt()` | **未包含** 父链上下文 | ❌ 断裂点 |
+| `_compute_call_chain_distribution()` | 读取了 `call_chains` | ✅ 但仅用于预计算提示 |
+| `prompts/attributor.txt` | **无** 调用栈搜索指引 | ❌ 断裂点 |
+
+## 2. 改进方案设计
+
+### 2.1 核心思路
+
+**利用 Perfetto slice 的 parent_id 链构建调用栈上下文,将"方法定义级别搜索"升级为"调用点级别搜索"。**
+
+具体策略:
+1. 在 `extract_attributable_slices()` 阶段,利用 `view_slices.call_chains` 和 `slowest_slices` 中的 `parent_id`,为每个可归因 slice 提取完整的父链上下文
+2. 将父链上下文编码为 `call_context` 字段,传递给 attributor agent
+3. Agent 搜索时利用上下文缩小搜索范围(如知道父 Activity 名、RV 实例 ID 等)
+4. 对无法通过上下文区分的场景,提供优先级排序而非全部列出
+
+### 2.2 技术方案
+
+#### 改动一:`extract_attributable_slices()` 增加调用栈提取
+
+**文件**: `src/smartinspector/commands/attribution.py`
+
+**当前代码**(第 552-707 行)只处理 `slowest_slices`、`summary`、`rv_instances`、`block_events`,未读取 `call_chains`。
+
+**改进**:在处理 `slowest_slices` 时,利用 `call_chains` 数据构建每个 slice 的调用上下文。
+
+```python
+# 新增函数
+def _build_parent_contexts(view_slices: dict) -> dict[int, str]:
+ """为每个 slowest_slice 构建 parent chain 上下文摘要。
+
+ 利用 collect_view_slices() 已构建的 call_chains 数据和 slice 的 parent_id,

+ if not parent_id or parent_id not in slice_by_id:
+ break
+ current = slice_by_id[parent_id]
+
+ chain.reverse() # root → leaf
+ return chain
+```
+
+#### 改动二:在 `extract_attributable_slices()` 中注入上下文
+
+**文件**: `src/smartinspector/commands/attribution.py`
+
+在函数末尾(约第 707 行),去重之后、排序之前,注入 `call_context`:
+
+```python
+def extract_attributable_slices(perf_summary_json: str, min_dur_ms: float = 1.0) -> list[dict]:
+ # ... 现有逻辑不变 ...
+
+ # ── 新增:注入调用栈上下文 ──
+ parent_contexts = _build_parent_contexts(view_slices)
+
+ for entry in seen.values():
+ raw_name = entry.get("raw_name", "")
+ if raw_name in parent_contexts:
+ entry["call_context"] = parent_contexts[raw_name]
+
+ # 对 RV 实例方法,补充 RV 上下文
+ if entry.get("instance"):
+ # instance 格式: RV#viewId#AdapterName
+ entry["call_context"] = f"RV实例: {entry['instance']}"
+
+ return sorted(seen.values(), key=lambda x: -x["dur_ms"])
+```
+
+#### 改动三:`_build_group_prompt()` 传递上下文给 LLM
+
+**文件**: `src/smartinspector/agents/attributor.py`
+
+修改 `_build_group_prompt()` 函数(第 390-428 行),在 prompt 中加入调用栈上下文:
+
+```python
+def _build_group_prompt(group: list[dict]) -> str:
+ """Build a search prompt for one group of issues."""
+ from smartinspector.config import get_source_dir
+
+ source_dir = get_source_dir()
+
+ lines = [
+ f"源码目录: {source_dir}\n",
+ ]
+
+ for i, issue in enumerate(group, 1):
+ search_type = issue.get("search_type", "java")
+ cn = issue["class_name"]
+ line = f"{i}. {cn}.{issue['method_name']} ({issue['dur_ms']:.2f}ms, {search_type}"
+ if issue.get("count"):
+ line += f", count={issue['count']}"
+
+ # ── 新增:调用栈上下文 ──
+ call_ctx = issue.get("call_context", "")
+ if call_ctx:
+ line += f", 调用链: {call_ctx}"
+
+ # BlockMonitor 堆栈(保留原有逻辑)
+ if issue.get("stack_trace"):
+ line += f", 堆栈:{issue['stack_trace'][0]}"
+
+ # 内部类提示(保留原有逻辑)
+ if "$" in cn:
+ outer = cn.split("$")[0]
+ line += f", 内部类:用Glob搜索外部类 {outer}"
+ line += f", RESULT行请用完整类名: {cn}.{issue['method_name']}"
+
+ # XML 布局提示(保留原有逻辑)
+ if search_type == "xml":
+ line += f", xml布局:Glob **/{cn}.xml → Read完整文件, RESULT行请用: {cn}.{issue['method_name']}"
+
+ line += ")"
+ lines.append(line)
+
+ # ... 后续代码不变 ...
+```
+
+#### 改动四:更新 attributor prompt,增加调用链搜索指引
+
+**文件**: `prompts/attributor.txt`
+
+在"核心原则"部分之后增加调用链上下文的使用指引:
+
+```
+## 调用链上下文(call_context)
+
+某些热点会附带调用链上下文信息,格式如:
+ `调用链: [帧渲染] → RV#recycler_orders#OrderAdapter.onCreateViewHolder`
+
+调用链的作用:
+1. **缩小搜索范围**:如果调用链包含具体的 Activity/Fragment 名称,
+ 说明热点发生在该 UI 组件上下文中,优先搜索该组件相关的类
+2. **区分同名方法**:如果多个 Adapter 有同名方法(如 onBindViewHolder),
+ 调用链中的 RV 实例 ID 和 Adapter 名称可以精确定位到具体的 Adapter 类
+3. **理解性能阶段**:调用链中的 [measure阶段]/[layout阶段]/[draw阶段]
+ 标识说明热点发生在 UI 渲染的哪个子阶段
+
+使用策略:
+- 调用链是辅助信息,不需要额外搜索调用链中提到的类
+- 当 Glob 搜索到多个同名文件时,优先选择与调用链上下文匹配的文件
+- 当 Grep 搜索到方法在多个位置出现时,优先选择与调用链描述一致的调用点
+```
+
+#### 改动五:`build_attribution_prompt()` 传递上下文给 explorer
+
+**文件**: `src/smartinspector/commands/attribution.py`
+
+在 `build_attribution_prompt()` 函数(第 744-792 行)中增加调用链上下文展示:
+
+```python
+def build_attribution_prompt(attributable: list[dict]) -> str:
+ # ... 现有逻辑 ...
+
+ for i, s in enumerate(attributable[:15], 1):
+ lines.append(f"### {i}. {s['class_name']}.{s['method_name']}")
+ lines.append(f" - 耗时: {s['dur_ms']:.2f}ms")
+ if s.get("instance"):
+ lines.append(f" - 实例: {s['instance']}")
+ if s.get("count"):
+ lines.append(f" - 调用次数: {s['count']}")
+ if s.get("total_ms"):
+ lines.append(f" - 总耗时: {s['total_ms']:.1f}ms")
+
+ # ── 新增:调用链上下文 ──
+ if s.get("call_context"):
+ lines.append(f" - 调用链上下文: {s['call_context']}")
+
+ if s.get("stack_trace"):
+ lines.append(f" - 堆栈采样 (BlockMonitor):")
+ for frame in s["stack_trace"][:12]:
+ lines.append(f" {frame}")
+ # ... 后续逻辑不变 ...
+```
+

+**场景 B:View.measure 热点嵌套在 doFrame 中**
+
+```

+ → Agent 不知道发生在哪个渲染阶段
+
+改进后: call_context = "[帧渲染] → [measure阶段] → DetailView.measure"

+ → 搜索时可以关联到 layout 布局分析
+```
+
+**场景 C:Activity 生命周期中的耗时操作**
+
+```
+输入: SI$Activity.lifecycle
+当前: class_name=Activity, method_name=lifecycle → system_class

+改进后: call_context = "handler(Worker.startWork)"(如果 parent 是 handler dispatch)
+ → Agent 知道是 startWork 方法中启动的匿名类

+| 同名 Adapter 的 onBindViewHolder | Glob 返回 3 个文件,Read 3 次 | Glob 返回 3 个文件,利用上下文只 Read 1 次 | ~2000 tokens/次 |
+| 同名方法多处调用 | Grep 返回 5+ 行,Read 5 次 | 利用上下文只 Read 1 次 | ~4000 tokens/次 |
+| 系统类误搜索 | 搜索后才发现是系统类 | 调用链标识了阶段,跳过系统类搜索 | ~1500 tokens/次 |
+
+### 4.2 减少歧义消除的 LLM 推理
+
+当前 LLM 在搜索到多个候选位置后,需要消耗 token 进行推理判断哪个是热点。改进后:
+- 调用链上下文直接消除了歧义
+- 减少 LLM "猜测" 的 token 消耗
+
+### 4.3 总体预估
+
+假设一次典型归因有 5-8 个可归因 slice,其中 2-3 个存在调用歧义:
+- **每次歧义消除节省**: ~1500-4000 tokens
+- **单次归因节省**: ~3000-8000 tokens
+- **占归因总 token 的比例**: 约 15%-30%
+
+增加的上下文信息 token 开销:
+- 每个 slice 的 call_context: ~20-50 tokens
+- 8 个 slice: ~160-400 tokens
+- prompt 增加的指引: ~200 tokens(一次性)
+
+**净节省: ~2500-7000 tokens/次归因**
+
+## 5. 风险和边界情况
+
+### 5.1 风险分析
+
+#### 风险 1:call_chains 覆盖率不足
+
+**现象**: `collect_view_slices()` 只为 top 10 slowest custom slices 构建 call_chains,但 `extract_attributable_slices()` 可能提取更多 slices。
+
+**缓解**: 改动一中的 `_build_parent_contexts()` 设计了策略2(parent_id 回溯),即使 call_chains 未覆盖,也能从 slowest_slices 中已有的 parent_id 信息向上回溯。
+
+**边界**: 如果 slice 的 parent_id 对应的 slice 不在 slowest_slices 中(因为 top 30 截断),回溯链会不完整。这是可接受的降级——此时 call_context 为空,退回到当前行为。
+
+#### 风险 2:parent_id 在 JSON 传递中丢失
+
+**现象**: `slowest_slices` 在构建时(`collect_view_slices()` 第 691-696 行)保留了 `id` 和 `parent_id`,但 `summary` 统计中没有这些字段。
+
+**缓解**: 只对 `slowest_slices` 中的 slice 提取 parent_context。`summary` 和 `rv_instances` 中的 slice 不需要调用链(它们是聚合数据,不是具体的单次调用)。
+
+#### 风险 3:调用链信息过长
+
+**现象**: 如果调用链很长(>5层),传递给 LLM 的 context 字符串过长,反而浪费 token。
+
+**缓解**: `_extract_context_from_chain()` 只保留 SI$ 自定义标签和阶段标识,过滤掉中间的系统标签。限制最大深度为 5 层。
+
+#### 风险 4:LLM 误用调用链信息
+
+**现象**: LLM 可能尝试搜索调用链中的其他类(如 parent chain 中的 Activity),导致额外的 Glob/Grep/Read 调用。
+
+**缓解**: 在 `prompts/attributor.txt` 中明确说明"调用链是辅助信息,不需要额外搜索调用链中提到的类"。
+
+### 5.2 边界情况
+
+| 边界情况 | 处理方式 |
+|---------|---------|
+| slice 没有 parent_id | call_context 为空,退回当前行为 |
+| parent_id 对应的 slice 不在结果集中 | 回溯链截断,只使用已知的链段 |
+| call_chains 为空(trace 无 SI$ 数据) | `_build_parent_contexts()` 返回空 dict |
+| atrace 截断了 SI$ tag 名称 | 调用链中可能出现不完整的 tag,_summarize_si_tag() 做了防御处理 |
+| 多个 slowest_slice 有相同 name | context 以 name 为 key,后出现的会覆盖(可接受:相同 name 的调用链结构通常相似) |
+| RV 实例方法的 instance 字段已包含上下文 | 优先使用 instance 作为上下文(见改动二中的优先级逻辑) |
+
+### 5.3 性能影响
+
+- `_build_parent_contexts()` 的计算开销可忽略(O(n) 遍历 + O(n*log(n)) 回溯)
+- 不增加任何 SQL 查询或文件 I/O
+- 增加的 JSON 字段约 100-500 bytes,对 token 预算影响极小
+
+## 6. 实施计划
+
+### Phase 1: 基础设施(改动一 + 改动二)
+
+在 `commands/attribution.py` 中实现 `_build_parent_contexts()` 及其辅助函数,修改 `extract_attributable_slices()` 注入 call_context。
+
+验证方式:构造包含 call_chains 的 view_slices JSON,确认 _build_parent_contexts() 输出正确。
+
+### Phase 2: Agent 集成(改动三 + 改动四)
+
+修改 `_build_group_prompt()` 和 `prompts/attributor.txt`,让 LLM 利用调用链上下文。
+
+验证方式:使用真实 trace 数据运行归因,检查 LLM 是否利用了调用链信息、是否减少了无效搜索。
+
+### Phase 3: Explorer 集成(改动五)
+
+修改 `build_attribution_prompt()`,将上下文传递给 explorer agent。
+
+验证方式:运行完整的 orchestrate 流程,检查最终报告是否包含更精确的归因信息。
+
+### Phase 4: 效果评估
+
+对比改进前后的:
+1. 归因精确度(能否定位到具体调用点而非方法定义)
+2. Token 消耗(归因阶段的 input/output token 总量)
+3. 搜索效率(Glob/Grep/Read 调用次数)
+
+## 7. 后续优化方向
+
+### 7.1 短期(本次改动基础上)
+
+- **调用链去重聚合**: 如果多个 slowest_slice 共享相同的 parent chain 前缀,在 prompt 中合并展示,避免重复
+- **上下文感知的 Grep 模式**: 当有 call_context 时,让 LLM 在 Grep 时使用更精确的 pattern(如类名+方法名+邻近上下文关键词)
+
+### 7.2 中期(需要额外数据采集)
+
+- **增强 collect_view_slices() 的 parent 回溯深度**: 当前只回溯到 grandparent(第 650-664 行),可考虑递归回溯到根节点(doFrame 级别)
+- **利用 track_id 区分线程上下文**: 当前只关注 main thread 的 slices,可扩展到分析 worker thread 的调用上下文
+
+### 7.3 长期(架构级改进)
+
+- **预计算调用链到源码行号的映射**: 在 deterministic.py 中预先匹配调用链中的 SI$ tag 到源码位置,减少 LLM 的搜索负担
+- **增量归因**: 对同一 RV 实例的多次调用,只搜索一次源码,后续复用结果

+```
+
+### 3.6 帧率信息
+
+HiDumper 本身不直接提供帧率数据。帧率采集需要通过以下方式:
+
+1. **hitrace**: 采集 `ace` + `graphic` tag 分析帧时间
+2. **SP_daemon**: 使用 `-f` 参数采集 FPS
+3. **Graphics Profiler**: DevEco Studio 内置工具

+## 4. hilog 日志系统
+
+### 4.1 日志格式
+
+hilog 日志格式:
+```
+<时间> <级别>: <消息>
+```
+
+示例:
+```
+01-01 12:00:00.000 I A03200[1234/5678]: This is an info log
+```
+
+**格式详解**:
+- `I` = Info 级别
+- `A03200` = A 表示应用日志, 3200 是 domainId (十六进制)
+- `[1234/5678]` = 进程号/线程号
+
+### 4.2 日志级别
+
+| 级别 | 字母 | 说明 |
+|------|------|------|
+| Debug | D | 调试信息 |
+| Info | I | 一般信息 |
+| Warn | W | 警告 |
+| Error | E | 错误 |
+| Fatal | F | 致命错误 |
+
+### 4.3 命令行用法
+
+```bash
+# 实时查看日志
+hdc shell hilog
+
+# 清除日志缓冲区
+hdc shell hilog -r
+
+# 按级别过滤 (D=Debug, I=Info, W=Warn, E=Error, F=Fatal)
+hdc shell hilog -l D # Debug 及以上
+hdc shell hilog -l E # Error 及以上
+
+# 按进程 PID 过滤
+hdc shell hilog -p
+
+# 组合过滤
+hdc shell "hilog -p -l D"
+
+# 按标签过滤
+hdc shell "hilog | grep "
+
+# 设置日志级别 (只输出指定级别及以上)
+hdc shell hilog -b D # Debug 及以上
+hdc shell hilog -b I # Info 及以上
+hdc shell hilog -b W # Warn 及以上
+hdc shell hilog -b E # Error 及以上
+hdc shell hilog -b F # Fatal
+```
+
+### 4.4 hilog 与 logcat 的差异
+
+| 对比项 | hilog (HarmonyOS) | logcat (Android) |
+|--------|-------------------|------------------|
+| 日志域 | domainId (十六进制) | tag (字符串) |
+| 级别格式 | 单字母在行首 `I A03200` | 级别字符后跟 tag `I/tag:` |
+| 进程标识 | `[pid/tid]` | `pid tid` |
+| 单条最大长度 | 4096 字节 | 4068 字节 |
+| 隐私标识 | 支持隐私参数格式化 `{private}` | 无内置 |
+| 过滤方式 | `-l` 级别, `-p` PID | `-s` tag, `*:level` |
+| 缓冲区 | ring buffer | log buffer (main/system/radio/events) |
+| 环境变量 | `HDC_SERVER_PORT` | `ANDROID_LOG_TAGS` |

+# SI改造方案 — 基于Perfetto+AI方案的对比分析
+
+> 生成日期:2026-04-22
+> 参考方案:基于Perfetto与AI的Android性能自动化诊断方案(Shell脚本方案)
+> 对照项目:AppSmartInspector(SI,LangGraph Agent方案)
+
+---
+
+## 一、两方案全景对比
+
+| 维度 | Shell脚本方案(参考文章) | SI Agent方案(当前项目) |
+|------|--------------------------|------------------------|
+| **架构** | 线性Pipeline:Shell入口 → Python SQL → Shell源码注入 → 远端LLM | LangGraph StateGraph:Orchestrator → Collector → Analyzer → Attributor → Reporter |
+| **采集** | `1_ai_sampler.sh` 手动构造perfetto textproto config | `PerfettoCollector.pull_trace_from_device()` Python构造config,支持ADB直连 |
+| **特征提取** | `2_trace_filter.py` 纯SQL查询 | `PerfettoCollector` 11个collect方法 + `deterministic.py` 预计算层 |
+| **源码关联** | `3_ai_reporter.sh` Shell脚本grep/find定位源码后直接拼入Prompt | Attributor Agent(LangChain agent + manual tool-call loop)动态 Glob→Grep→Read |
+| **AI诊断** | 单次远端LLM调用,全量源码注入Prompt | 多Agent协作:PerfAnalyzer(预计算+LLM)→ Attributor(LLM+工具)→ Reporter(LLM) |
+| **用户交互** | `run_profiler.sh` 入口,无交互 | REPL交互式CLI + Perfetto UI插件 + WebSocket实时通信 |
+| **可扩展性** | 添加新SQL查询需改脚本 | 添加新collect方法 + 新Agent即可,模块化 |
+| **依赖** | Shell + Python + Perfetto CLI | Python + LangGraph + LangChain + Perfetto SDK + WebSocket |
+
+---
+
+## 二、逐维度深度对比
+
+### 2.1 Trace采集
+
+**Shell方案:**
+- 通过Shell脚本 `1_ai_sampler.sh` 构造Perfetto textproto配置
+- 使用 `perfetto -c - --txt` 命令行模式,通过cat管道绕过SELinux限制
+- 采集类别:sched freq idle am wm gfx view binder_driver hal dalvik memory(11个atrace类别)
+- 增加了 `linux.perf`(CPU函数采样)+ Frame Timeline + `linux.process_stats`
+- `target_cmdline` 限定只对目标应用展开调用栈解析
+- 自动降级:config模式失败时降级到命令行模式
+
+**SI方案:**
+- `PerfettoCollector.pull_trace_from_device()` 在Python中构造完整textproto配置
+- 同样包含atrace类别 + Frame Timeline + `linux.perf` + `linux.process_stats`
+- 额外支持 `android.java_hprof`(Java堆内存分析)和 `android.log`(logcat采集)
+- 通过ADB直接执行perfetto命令
+- 自动检测前台应用包名(`adb shell dumpsys`)
+
+**对比评估:**
+
+| 采集能力 | Shell方案 | SI方案 | 优势方 |
+|---------|-----------|--------|--------|
+| 基础atrace | 11类别 | 11类别 | 持平 |
+| CPU函数采样 | linux.perf | linux.perf | 持平 |
+| Frame Timeline | 支持 | 支持 | 持平 |
+| Java堆分析 | 未提及 | java_hprof | **SI** |
+| Logcat采集 | 未提及 | android.log | **SI** |
+| SELinux绕过 | cat管道方案 | 未专门处理 | **Shell** |
+| 自动降级 | 有 | 无 | **Shell** |
+| 包名检测 | 手动传入 | 自动检测 | **SI** |
+| 进程过滤 | target_cmdline | target_cmdline | 持平 |
+
+**SI可借鉴:**
+1. **SELinux绕过策略**:参考Shell方案的cat管道方式(`cat config.pb | perfetto -c -`),增加在受限设备上的兼容性
+2. **自动降级机制**:当config模式启动perfetto失败时,自动降级到命令行模式继续采集
+3. **UID获取策略**:Shell方案通过 `linux.process_stats` 扫描 `/proc` 获取UID,解决冷启动阶段 `process` 表无数据时的包名匹配问题。SI目前依赖 `process` 表,可能在冷启动场景遗漏
+
+---
+
+### 2.2 特征提取(SQL查询)
+
+**Shell方案:**
+- `2_trace_filter.py` 核心是直接的SQL查询
+- 查询维度覆盖:慢切片、线程状态、帧时间线、CPU采样、调用栈
+- 关键特性:
+ - 使用 `thread_state` 表区分"代码慢"还是"线程被挂起"(Running vs R/S/D)
+ - `actual_frame_timeline_slice` 帧级归因,区分App/SF问题
+ - `perf_sample` + `stack_profile_callsite` CPU调用栈链表(Android 15+)
+ - `args` 表读取Slice附加参数(view_type, adapter_position)
+ - `package_list` 冷启动场景的反查表
+
+**SI方案:**
+- `PerfettoCollector` 的11个collect方法
+- `deterministic.py` 预计算层(纯Python,无LLM):
+ - 空场景检测(FPS=0, 无帧, CPU低)
+ - 严重度分类(P0/P1/P2,按设备帧预算动态阈值)
+ - 调用链时间分布(百分比 + 树形缩进)
+ - RV热点排名(max_ms, avg_ms)
+ - 卡顿帧关联(帧-Slice-输入事件三方关联)
+ - CPU热点识别
+- SI$自定义Tag系统:block/RV/inflate/view/handler/db/net/img/touch
+- Block事件与Perfetto Slice通过timestamp bisect关联
+
+**对比评估:**
+
+| 特征提取能力 | Shell方案 | SI方案 | 优势方 |
+|-------------|-----------|--------|--------|
+| 慢切片SQL | 直接查询 | collect_view_slices | 持平 |
+| 线程状态分析 | thread_state表区分R/S/D | collect_sched (end_state) | **Shell** |
+| 帧时间线 | actual_frame_timeline_slice | collect_frame_timeline + expected | **SI** |
+| CPU采样调用栈 | stack_profile_callsite链表 | collect_cpu_hotspots + 调用链重建 | 持平 |
+| Slice附加参数 | args表 (view_type, adapter_position) | collect_view_slices (已解析) | 持平 |
+| 冷启动场景 | package_list反查 | 未专门处理 | **Shell** |
+| 确定性预计算 | 无 | deterministic.py 六大模块 | **SI** |
+| 动态阈值 | 固定阈值 | 按设备帧预算自动调整 | **SI** |
+| 帧级归因 | jank_type区分App/SF | USER_JANK_TYPES分类 | 持平 |
+| 自定义Tag | 依赖atrace原生tag | SI$自定义Tag体系(覆盖8类场景) | **SI** |
+
+**SI可借鉴:**
+1. **thread_state深度分析**:Shell方案利用 `thread_state` 表区分线程在Running(代码慢)和 S/D(被挂起/IO等待)状态的时间分布。SI的 `collect_sched` 只有end_state,缺少per-slice级别的线程状态分析。建议增加 `thread_state` 查询,将每个慢Slice关联其执行期间的线程状态分布,帮助区分"代码需要优化"和"线程被系统挂起"两种不同根因
+2. **package_list冷启动支持**:在冷启动场景中 `process` 表可能为空,Shell方案用 `package_list` 反查。SI应在 `pull_trace_from_device` 的config中确保 `linux.process_stats` 开启,并在包名匹配失败时 fallback 到 `package_list` 查询
+3. **CPU采样调用栈深度重建**:Shell方案通过 `stack_profile_callsite.parent_id` 递归重建完整调用链。SI的 `collect_cpu_hotspots` 已实现类似逻辑(callsite_map + 递归回溯),但可增加对 `stack_profile_mapping` 的查询,关联so/apk的映射信息,使native方法调用栈更可读
+
+---
+
+### 2.3 源码关联
+
+**Shell方案:**
+- `3_ai_reporter.sh` 纯Shell脚本实现
+- 流程:从trace_filter输出中提取类名 → 用find/grep在源码中定位文件 → 用sed/awk提取方法体 → 直接拼入AI Prompt
+- 源码搜索范围:当前class文件 + import依赖 + 关联XML布局
+- 特点:
+ - **静态绑定**:在Prompt构造阶段一次性完成所有源码搜索
+ - **确定性**:不依赖LLM做搜索决策,纯Shell脚本逻辑
+ - **广度**:搜索依赖引用和关联XML布局,提供更完整的上下文
+
+**SI方案:**
+- `Attributor Agent` — LangChain agent with manual tool-call loop
+- 流程:提取SI$切片 → 分类(java/xml/system)→ 分组 → 对每组执行 Glob→Grep→Read 三步搜索
+- 特点:
+ - **动态搜索**:LLM决定搜索策略,可以处理模糊/不规则的类名
+ - **工具调用循环**:最多8轮迭代,LLM自主决定何时搜索完成
+ - **Call Stack上下文**:利用parent chain和BlockMonitor堆栈辅助定位
+ - **内部类处理**:匿名内部类($1/$2) → 搜索外部类 → 堆栈提取真实方法名
+ - **LRU缓存**:避免重复读取文件
+ - **Early termination**:连续3次搜索失败则终止
+ - **结构化输出**:尝试with_structured_output,失败时fallback到RESULT行解析
+
+**对比评估:**
+
+| 源码关联能力 | Shell方案 | SI方案 | 优势方 |
+|-------------|-----------|--------|--------|
+| 搜索策略 | 静态find/grep/sed | 动态LLM Glob→Grep→Read | **SI** |
+| 搜索准确性 | 依赖类名匹配规则 | LLM理解模糊/不规则名称 | **SI** |
+| 搜索范围 | 当前类+import依赖+XML | 当前类+内部类+堆栈提示 | **Shell**(依赖链更广) |
+| 搜索效率 | 一次性Shell脚本,快速 | 多轮LLM调用,较慢 | **Shell** |
+| 匿名内部类 | 未专门处理 | 完整处理(外部类+堆栈方法名) | **SI** |
+| 错误容忍 | Shell脚本出错即中断 | Early termination + 缓存 + 重试 | **SI** |
+| Token消耗 | 无(不使用LLM搜索) | 高(每轮LLM调用消耗token) | **Shell** |
+| 上下文完整性 | 包含import依赖和关联XML | 仅搜索目标类和方法体 | **Shell** |
+| BlockMonitor堆栈 | 未提及 | 堆栈关联+bisect时间匹配 | **SI** |
+| 调用链上下文 | 无 | parent chain回溯+上下文摘要 | **SI** |
+
+**SI可借鉴:**
+1. **依赖引用搜索**:当前SI只搜索目标类本身的方法体。Shell方案会额外搜索该类的import依赖和关联XML布局,为AI诊断提供更完整的上下文。建议在Attributor Agent中增加一步"关联搜索":Read目标文件后,提取import列表中的项目内类和关联的XML布局ID,一并读取
+2. **搜索效率优化**:Shell方案一次性完成所有源码搜索,而SI需要多轮LLM调用。对于类名和包名完整的简单场景,可以引入"快速路径":跳过LLM搜索决策,直接用确定性代码执行Glob→Grep→Read。只在模糊/匿名内部类场景才走LLM搜索路径
+3. **静态源码绑定模式**:提供一种"预处理模式"选项,在调用LLM之前先用确定性代码完成源码搜索,将结果直接注入Prompt,类似Shell方案的做法。好处是减少token消耗和LLM调用轮次
+
+---
+
+### 2.4 AI诊断
+
+**Shell方案:**
+- 单次LLM调用
+- 将SQL查询结果+源码片段一起注入Prompt
+- LLM直接输出Markdown诊断报告
+- 优点:简单直接,一次调用完成
+- 缺点:LLM需要同时处理数据分析和报告生成两个任务,可能导致质量下降
+
+**SI方案:**
+- 三阶段Agent协作:
+ 1. **PerfAnalyzer**:接收deterministic预计算结论 + 原始数据 → 组织性能分析报告
+ 2. **Attributor**:根据SI$切片搜索源码 → 返回归因结果(文件路径+方法体+行号)
+ 3. **Reporter**:综合性能分析 + 源码归因 + 待归因热点 → 生成最终报告
+- **混合架构**:确定性计算(deterministic.py)+ LLM语言生成
+- **Token控制**:消息窗口裁剪、LRU文件缓存、结构化输出探测、Early termination
+- **多Provider支持**:结构化输出失败时自动fallback到文本解析
+
+**对比评估:**
+
+| AI诊断能力 | Shell方案 | SI方案 | 优势方 |
+|-----------|-----------|--------|--------|
+| LLM调用次数 | 1次 | 3-5次(per_analyzer + attributor迭代 + reporter) | **Shell**(简单) |
+| 分析精度 | 依赖LLM做算术 | 确定性预计算+LLM语言组织 | **SI** |
+| 源码上下文 | 预注入完整源码 | 动态搜索+精准方法体 | **SI**(灵活) |
+| 报告质量 | 单次输出 | 分层生成+格式化 | **SI** |
+| Token消耗 | 低 | 高(多轮对话) | **Shell** |
+| 错误恢复 | 无 | 重试+fallback+graceful degrade | **SI** |
+| 可扩展性 | 硬编码Prompt | 模块化Agent+独立Prompt文件 | **SI** |
+| 结果一致性 | 完全依赖LLM | 确定性部分保证一致 | **SI** |
+
+**SI可借鉴:**
+1. **轻量模式**:参考Shell方案的单次调用模式,为SI增加一个"快速诊断"模式。跳过Attributor阶段,直接将perf_summary中的类名/方法名/耗时信息交给Reporter LLM,由LLM基于经验推测优化建议。适用场景:不需要精确源码定位的快速初筛
+2. **Token消耗优化**:Shell方案的Prompt是静态构造的,token消耗可控。SI的Attributor Agent每轮迭代都会增加消息历史。当前的消息窗口裁剪(keep last 12 messages)和max 8 iterations是好的防护措施,但可进一步优化:对于确定性高的场景(FQN完整、方法名明确),直接执行工具调用不经过LLM决策

+
+### 2.5 系统架构
+
+**Shell方案:**
+```
+run_profiler.sh
+ ├── 1_ai_sampler.sh # Trace采集
+ ├── 2_trace_filter.py # SQL特征提取
+ └── 3_ai_reporter.sh # 源码注入 + AI诊断
+```
+- 线性Pipeline,阶段间通过文件传递数据
+- 每个阶段独立可执行
+- 依赖少:只需Shell + Python + curl/LLM API
+
+**SI方案:**
+```
+LangGraph StateGraph
+ orchestrator → collector → analyzer → attributor → reporter
+ android_expert perf_analyzer
+ explorer
+```
+- 状态机架构,通过AgentState传递数据
+- 条件路由:根据用户意图分发到不同处理路径
+- REPL交互式CLI + Perfetto UI WebSocket集成
+- 依赖多:LangGraph + LangChain + WebSocket + Perfetto SDK
+
+**对比评估:**
+
+| 架构特性 | Shell方案 | SI方案 | 优势方 |
+|---------|-----------|--------|--------|
+| 复杂度 | 低(3个脚本) | 高(多Agent系统) | **Shell**(简单) |
+| 可维护性 | Shell脚本维护困难 | Python模块化,可维护 | **SI** |
+| 可扩展性 | 修改脚本,耦合高 | 添加Agent/Node即可 | **SI** |
+| 部署难度 | 低(仅需Shell环境) | 高(Python环境+依赖) | **Shell** |
+| 交互性 | 无交互 | REPL + Perfetto UI | **SI** |
+| 状态管理 | 文件传递 | AgentState TypedDict | **SI** |
+| 错误处理 | 脚本失败即中断 | node_error_handler + 全局try/except | **SI** |
+| 并发安全 | 无 | thread-safe LLM singleton + Lock | **SI** |
+| 实时反馈 | 无 | WebSocket进度推送 | **SI** |
+
+---
+
+### 2.6 用户体验
+
+**Shell方案:**
+- 命令行执行 `run_profiler.sh <包名>`
+- 无交互,全自动化
+- 输出:Markdown诊断报告文件
+- 适用场景:CI/CD集成、批量测试
+
+**SI方案:**
+- 交互式REPL(`smartinspector`命令)
+- 21个Slash命令(/full、/trace、/frame、/open等)
+- Perfetto UI集成:浏览器中选择时间范围 → Agent实时分析
+- WebSocket实时进度推送
+- 多种交互模式:自然语言、命令、UI选择
+- 适用场景:开发阶段调试、性能问题深入分析
+
+**对比评估:**
+
+| 用户体验 | Shell方案 | SI方案 | 优势方 |
+|---------|-----------|--------|--------|
+| 上手难度 | 低(一条命令) | 中(需学习命令和交互) | **Shell** |
+| 灵活性 | 低(固定Pipeline) | 高(多种入口和交互方式) | **SI** |
+| CI/CD集成 | 天然适合 | 需封装 | **Shell** |
+| 深度分析 | 浅(一次性报告) | 深(交互式追问、时间范围选择) | **SI** |
+| 可视化 | 无 | Perfetto UI集成 | **SI** |
+| 实时反馈 | 无 | 进度条 + 工具调用展示 | **SI** |
+
+**SI可借鉴:**
+1. **Headless/CI模式**:参考Shell方案的"一条命令全流程"设计,为SI增加非交互模式。例如 `smartinspector --headless --package com.example.app --duration 10` 直接完成采集→分析→报告,适合CI/CD集成
+2. **输出标准化**:Shell方案的输出是一个完整的Markdown文件,可直接作为测试报告。SI的报告已很完善(含header tables + 问题列表),可增加机器可读的JSON输出选项,方便CI系统解析
+
+---
+
+## 三、SI可借鉴的改进点汇总
+
+按优先级排序(P0=高优先级,P1=中优先级,P2=低优先级):
+
+### P0:核心能力提升
+
+#### 1. thread_state深度分析 — 区分"代码慢"vs"被挂起"
+- **现状**:SI的 `collect_sched` 只查询调度统计和blocked_reason,没有per-slice级别的线程状态分析
+- **改进**:新增 `collect_thread_state` 方法,查询 `thread_state` 表,对每个SI$慢Slice关联其执行期间的状态分布(Running/S/D)
+- **价值**:帮助开发者区分"代码需要优化"和"线程被IO/锁阻塞"两种根本不同的根因
+- **参考SQL**:
+ ```sql
+ SELECT ts, dur, state
+ FROM thread_state
+ WHERE utid = (SELECT utid FROM thread WHERE name = 'main')
+ AND ts >= {slice_ts} AND ts + dur <= {slice_ts} + {slice_dur}
+ ```
+
+#### 2. 源码搜索"快速路径" — 确定性搜索减少LLM调用
+- **现状**:所有源码搜索都走Attributor Agent的LLM工具调用循环
+- **改进**:对于FQN完整、方法名明确的场景(非匿名内部类、非模糊匹配),直接用Python代码执行Glob→Grep→Read,不经过LLM决策
+- **价值**:减少50%+的token消耗和响应时间
+- **实现**:在 `_search_group()` 前增加确定性搜索判断
+ ```python
+ if all(issue.get("search_type") == "java" and "$" not in issue["class_name"] for issue in group):
+ results = _deterministic_search(group, file_cache)
+ if all(r["reason"] == "found" for r in results):
+ return results # 跳过LLM
+ ```
+
+#### 3. Headless/CI模式 — 一条命令完成全流程
+- **现状**:SI只支持交互式REPL
+- **改进**:增加CLI参数 `--headless`,跳过交互直接执行 full pipeline
+- **价值**:适合CI/CD集成和批量测试
+
+### P1:体验和完整性提升
+
+#### 4. 依赖引用搜索 — 扩展源码上下文
+- **现状**:Attributor只搜索目标类的方法体
+- **改进**:Read目标文件后,提取import列表中的项目内类和XML布局ID,一并搜索
+- **价值**:为AI诊断提供更完整的上下文,提升诊断准确度
+- **实现**:在Attributor Agent的Read后增加一步"关联分析"
+
+#### 5. package_list冷启动支持
+- **现状**:SI依赖 `process` 表获取包名,冷启动场景可能匹配失败
+- **改进**:在包名匹配失败时,fallback到 `package_list` 表反查
+- **价值**:支持冷启动性能分析场景
+- **实现**:修改 `pull_trace_from_device` 确保config包含 `linux.process_stats`,在 `collect_view_slices` 中增加 `package_list` fallback
+
+#### 6. SELinux兼容性 — cat管道绕过
+- **现状**:SI直接执行 `perfetto -c -` 命令
+- **改进**:增加cat管道方案作为fallback(`cat config.pb | perfetto -c -`)
+- **价值**:在受限设备上正常采集
+
+#### 7. Perfetto采集自动降级
+- **现状**:config模式失败时报错
+- **改进**:自动降级到命令行模式(类似Shell方案)
+- **价值**:提高采集成功率
+
+### P2:长期演进
+
+#### 8. stack_profile_mapping关联 — Native调用栈可读性
+- **现状**:`collect_cpu_hotspots` 只重建函数调用链,不关联so/apk映射
+- **改进**:增加 `stack_profile_mapping` 查询,关联native库信息
+- **价值**:提升native方法调用栈的可读性
+
+#### 9. 轻量快速诊断模式
+- **现状**:每次诊断都走完整Attributor流程
+- **改进**:增加"快速模式"跳过Attributor,由LLM基于经验推测
+- **价值**:快速初筛,减少等待时间
+
+#### 10. JSON格式机器可读输出
+- **现状**:只输出Markdown报告
+- **改进**:增加JSON输出选项,包含结构化的问题列表和源码定位结果
+- **价值**:CI系统可解析,支持自动化处理
+
+---
+
+## 四、SI架构优势总结
+
+SI相比Shell脚本方案的核心优势:
+
+1. **混合确定性+LLM架构**:算术和阈值分类由deterministic.py保证准确性,LLM只负责语言组织和因果分析。这是最关键的架构优势
+2. **SI$自定义Tag体系**:覆盖block/RV/inflate/view/handler/db/net/img/touch八大场景,远比依赖atrace原生tag精准
+3. **动态源码搜索**:Attributor Agent的LLM工具调用循环可以处理匿名内部类、模糊类名等复杂场景,比Shell的find/grep灵活得多
+4. **交互式分析**:REPL + Perfetto UI集成,支持深度追问和时间范围选择
+5. **模块化可扩展**:LangGraph状态机 + 独立Agent + 独立Prompt文件,添加新功能只需添加新Node
+6. **BlockMonitor集成**:主线程卡顿检测 + 堆栈关联 + bisect时间匹配,填补Hook覆盖的盲区
+
+SI当前的不足:
+1. **Token消耗高**:多轮LLM调用,Attributor尤其消耗token
+2. **响应时间长**:LLM搜索+多Agent串行执行
+3. **CI集成困难**:缺少非交互模式
+4. **线程状态分析浅**:缺少per-slice级别的Running/S/D区分
+
+---
+
+## 五、实施建议
+
+### 阶段一:核心能力补强
+1. 新增 `collect_thread_state` 方法(P0-1)
+2. 实现源码搜索快速路径(P0-2)
+3. 新增Headless CLI模式(P0-3)
+
+### 阶段二:鲁棒性提升
+4. package_list冷启动fallback(P1-5)
+5. SELinux兼容性改进(P1-6)
+6. Perfetto采集自动降级(P1-7)
+7. 依赖引用搜索扩展(P1-4)
+
+### 阶段三:长期演进
+8. Native调用栈可读性(P2-8)
+9. 快速诊断模式(P2-9)
+10. JSON机器可读输出(P2-10)
+
+每个改进点都可以独立实现和测试,不影响现有功能。建议按阶段推进,每个阶段完成后进行回归测试。

+# SI Agent x Perfetto UI 联动分析:可行性评估与设计方案
+
+> 日期:2026-04-15
+> 状态:可行性调研完成,待实施
+
+## 一、需求概述
+
+用户在 Perfetto UI 中打开 trace 文件,浏览并选中耗时帧后,SI Agent 自动获取选中帧的详细数据,调用 LLM 进行深度分析(包括调用链归因、源码定位),并将分析结果实时展示给用户。
+
+**核心价值**:将"全量自动分析"升级为"用户驱动的交互式分析",用户可聚焦关心的帧,获得更精准的分析结果。
+
+## 二、现有架构概览
+
+### 2.1 核心数据流
+
+```
+用户输入 -> orchestrator(路由) -> collector(采集trace) -> analyzer(LLM分析)
+ -> attributor(源码归因) -> reporter(生成报告)
+```
+
+- **collector** 调用 `PerfettoCollector.pull_trace_from_device()` 通过 `adb shell perfetto` 采集 `.pb` trace 文件
+- 使用 `trace_processor_shell` (Python API `perfetto.TraceProcessor`) 执行 SQL 查询
+- 产出 `PerfSummary` JSON,包含 `frame_timeline`、`view_slices`、`block_events` 等
+
+### 2.2 WebSocket 现状
+
+`ws/server.py` 中 `SIServer` 是单例 WebSocket 服务器,与 Android App 通信:
+
+| 方向 | 消息类型 | 用途 |
+| ---------- | ------------------------------------ | ---------------- |
+| App->Server | `config_sync`, `block_events`, `ack` | 配置同步、事件上报 |
+| Server->App | `config_update`, `start_trace`, `get_block_events` | 推送配置、触发采集 |
+
+**协议特点**:JSON 消息、UUID msg_id、ACK 确认、threading.Event 阻塞等待。扩展新消息类型只需在 `_dispatch()` 中添加 `elif` 分支。
+
+### 2.3 帧数据能力
+
+- `collect_frame_timeline()`:查询 `actual/expected_frame_timeline_slice`,检测 jank、计算 FPS、返回 top10 最慢帧
+- `collect_view_slices()`:查询 SI$ 自定义 slice,重建调用链(parent->grandparent),输出 slowest_slices / call_chains / rv_instances
+- `compute_hints()`:确定性预计算(P0/P1/P2 严重度、jank 帧关联、CPU 热点)
+- `extract_attributable_slices()`:从 view_slices 中过滤出可归因的 SI$ slice(排除系统类)
+
+## 三、Perfetto UI 扩展能力调研
+
+### 3.1 Plugin 系统(最强大)
+
+Perfetto UI 拥有完整的 Plugin API:
+
+| 扩展点 | API | 描述 |
+| ---------------- | ---------------------------------------- | ------------------------------------ |
+| 自定义 Track | `trace.tracks.registerTrack()` | 注册 slice/counter/自定义 canvas track |
+| 时间线 Overlay | `trace.tracks.registerOverlay()` | 在时间线上绘制箭头、标注、竖线 |
+| Tab 面板 | `trace.registerTab()` | 在详情面板添加标签页 |
+| 命令 | `app.commands.registerCommand()` | 注册命令面板操作+快捷键 |
+| 侧边栏 | `trace.sidebar.addMenuItem()` | 添加侧边栏菜单项 |
+| 区域选择 Tab | `trace.selection.registerAreaSelectionTab()` | 选择时间范围时显示自定义面板 |
+| 时间线标注 | `trace.notes.addSpanNote()` | 添加高亮时间范围 |
+| 编程式选择 | `trace.selection.selectTrackEvent()` | 程序化选中某个 slice |
+
+**关键限制**:所有 Plugin 必须是 in-tree(提交到 google/perfetto 仓库),或自行 fork 托管。不支持动态加载外部插件。
+
+### 3.2 URL Deep Linking
+
+```
+https://ui.perfetto.dev/#!/?url=&visStart=&visEnd=&ts=&dur=
+```
+
+- `url`:自动打开远程 trace 文件(需 HTTPS + CORS)
+- `visStart/visEnd`:初始视口范围(纳秒)
+- `ts/dur`:定位并选中特定 slice
+- `startupCommands`:JSON 数组,自动执行命令(PinTracks、AddDebugTrack、RunQuery 等)
+- `embed`:嵌入模式,隐藏侧边栏
+
+### 3.3 iframe + postMessage
+
+```javascript
+// 父窗口向 iframe 中的 Perfetto UI 发送 trace
+iframe.contentWindow.postMessage({
+ perfetto: { buffer: arrayBuffer, title: 'My Trace' }
+}, 'https://ui.perfetto.dev');
+
+// 控制视口
+iframe.contentWindow.postMessage({
+ perfetto: { timeStart: 123.456, timeEnd: 123.789 }
+}, 'https://ui.perfetto.dev');
+```
+
+**限制**:postMessage 只接受来自 `window.opener`、`window.parent` 或 opener 关系窗口的消息,background script 发送的消息会被忽略。
+
+### 3.4 trace_processor_shell HTTP 模式
+
+```bash
+trace_processor_shell server http trace_file.pb --port 9001
+```
+
+| 端点 | 用途 |
+| ----------- | ------------------------------------------------- |
+| `/websocket` | Protobuf-over-WebSocket,Perfetto UI 的主要通信通道 |
+| `/rpc` | HTTP POST + Protobuf,Python API 使用 |
+| `/query` | 执行 SQL 查询 |
+| `/status` | Trace processor 状态 |
+
+Perfetto UI 自动检测 localhost:9001 并启用 "Trace Processor native acceleration"。
+
+### 3.5 Chrome Extension
+
+**可行性低**。content script 运行在隔离世界,无法访问 Perfetto UI 内部 JS API。只能通过 iframe+postMessage 间接交互,或操作 DOM。
+
+## 四、技术方案设计
+
+### 4.1 方案对比
+
+| 方案 | 优点 | 缺点 | 推荐度 |
+| --------------------------------- | ------------------------------------------ | --------------------------------- | ------ |
+| A: Fork Perfetto + 自定义 Plugin | 最强控制力,可注册自定义 Tab/命令/Overlay | 需维护 fork,构建复杂 | 3/5 |
+| B: 本地 HTTP Server + iframe 嵌入 | 自托管 UI,绕过跨域限制,可注入 JS | 需要构建和部署 UI | 3/5 |
+| C: trace_processor HTTP + Chrome Extension | 不修改 Perfetto,独立扩展 | Extension 能力受限,交互不自然 | 2/5 |
+| **D: 本地 Web Server 桥接(推荐)** | **最小侵入,利用现有 WS 架构,独立前端页面** | **需开发桥接前端** | **5/5**|
+
+### 4.2 推荐方案:本地 Web Server 桥接
+
+**核心思路**:不修改 Perfetto UI,在 SI Agent 侧构建一个轻量 Web Server 作为桥接层。
+
+```
++-----------------------------------------------------------+
+| 浏览器 |
+| +------------------------+ +--------------------------+ |
+| | 桥接页面 (localhost) | | Perfetto UI (iframe) | |
+| | - JS 拦截用户选中 | | - 打开 trace | |
+| | - WS 发送到 Agent | | - postMessage 控制 | |
+| | - 显示分析结果 | | | |
+| +----------+-------------+ +--------------------------+ |
+| | WS (localhost:9877) |
++-------------+----------------------------------------------+
+ |
++-------------+----------------------------------------------+
+| SI Agent (Python) |
+| +----------+-------------+ +--------------------------+ |
+| | Web Bridge Server | | trace_processor_shell | |
+| | (aiohttp/websockets) | | HTTP mode :9001 | |
+| | - 接收帧选中事件 | | - SQL 查询 | |
+| | - 调用 Agent 分析 | | - 与 Perfetto UI 直连 | |
+| +----------+-------------+ +--------------------------+ |
+| | |
+| +----------+-------------------------------------------+ |
+| | LangGraph Pipeline (现有架构) | |
+| | collector -> analyzer -> attributor -> reporter | |
+| +------------------------------------------------------+ |
++-----------------------------------------------------------+
+```
+
+### 4.3 关键技术细节
+
+#### 4.3.1 trace_processor_shell HTTP 模式启动
+
+```python
+# collector/perfetto.py 扩展
+import subprocess
+
+class TraceServer:
+ """管理 trace_processor_shell HTTP 服务"""
+
+ def __init__(self, trace_path: str, port: int = 9001):
+ self.trace_path = trace_path
+ self.port = port
+ self.process: subprocess.Popen | None = None
+
+ def start(self):
+ self.process = subprocess.Popen(
+ [SHELL_BIN, "server", "http", self.trace_path,
+ "--port", str(self.port), "--ip-address", "127.0.0.1"],
+ stdout=subprocess.PIPE, stderr=subprocess.PIPE
+ )
+ # 等待就绪
+ import urllib.request
+ for _ in range(50):
+ try:
+ urllib.request.urlopen(f"http://127.0.0.1:{self.port}/status")
+ return True
+ except Exception:
+ time.sleep(0.1)
+ return False
+
+ def query(self, sql: str) -> list[dict]:
+ """通过 HTTP RPC 执行 SQL"""
+ from perfetto.trace_processor import TraceProcessor
+ tp = TraceProcessor(addr=f'localhost:{self.port}')
+ result = tp.query(sql)
+ return result.as_dict()['rows']
+
+ def stop(self):
+ if self.process:
+ self.process.terminate()
+```
+
+#### 4.3.2 桥接 Web Server
+
+```python
+# ws/bridge_server.py (新增)
+import asyncio
+import json
+from aiohttp import web
+
+class BridgeServer:
+ """桥接浏览器与 SI Agent 的 Web Server"""
+
+ def __init__(self, port: int = 9877, agent_callback=None):
+ self.port = port
+ self.agent_callback = agent_callback # 回调:帧选中 -> Agent 分析
+ self.ws_clients: set[web.WebSocketResponse] = set()
+
+ async def handle_websocket(self, request):
+ ws = web.WebSocketResponse()
+ await ws.prepare(request)
+ self.ws_clients.add(ws)
+ try:
+ async for msg in ws:
+ data = json.loads(msg.data)
+ if data['type'] == 'frame_selected':
+ # 用户在 Perfetto UI 中选中了一个帧/slice
+ result = await self.agent_callback(data['payload'])
+ await ws.send_json({
+ 'type': 'analysis_result',
+ 'payload': result
+ })
+ finally:
+ self.ws_clients.remove(ws)
+
+ async def handle_index(self, request):
+ """返回桥接页面 HTML"""
+ return web.Response(text=BRIDGE_HTML, content_type='text/html')
+
+ def start(self):
+ app = web.Application()
+ app.router.add_get('/', self.handle_index)
+ app.router.add_get('/ws', self.handle_websocket)
+ web.run_app(app, port=self.port)
+```
+
+#### 4.3.3 桥接前端页面核心逻辑
+
+```javascript
+// 桥接页面 (嵌入 Perfetto UI iframe + 拦截选中事件)
+const PERFETTO_URL = 'https://ui.perfetto.dev';
+
+// 1. 通过 URL 打开 trace(trace_processor 在 localhost:9001)
+const iframe = document.getElementById('perfetto');
+iframe.src = `${PERFETTO_URL}/#!/?url=http://127.0.0.1:9001`;
+
+// 2. 监听 iframe 消息 + 定时查询选中状态
+// Perfetto UI 没有直接暴露"选中变化"事件,
+// 需要通过以下策略之一获取选中信息:
+
+// 策略A:用户手动触发(推荐 MVP)
+// 用户选中 slice 后点击"分析"按钮,页面读取 URL hash 中的 ts/dur
+document.getElementById('analyzeBtn').addEventListener('click', () => {
+ const hash = iframe.contentWindow.location.hash;
+ const params = new URLSearchParams(hash.split('?')[1] || '');
+ const ts = params.get('ts');
+ const dur = params.get('dur');
+ if (ts && dur) {
+ ws.send(JSON.stringify({ type: 'frame_selected', payload: { ts, dur } }));
+ }
+});
+
+// 策略B:MutationObserver 监听 DOM 变化(高级)
+// Perfetto UI 选中 slice 后会更新详情面板 DOM
+const observer = new MutationObserver(() => {
+ const details = iframe.contentDocument.querySelector(
+ 'details-panel .slice-details'
+ );
+ if (details) {
+ const ts = details.dataset.ts;
+ const dur = details.dataset.dur;
+ // 发送到 Agent...
+ }
+});
+
+// 策略C:轮询 URL hash 变化(最简单可靠)
+let lastHash = '';
+setInterval(() => {
+ const hash = iframe.contentWindow.location.hash;
+ if (hash !== lastHash) {
+ lastHash = hash;
+ const params = new URLSearchParams(hash.split('?')[1] || '');
+ if (params.get('ts')) {
+ // 用户导航到了新的位置,可以自动触发分析
+ }
+ }
+}, 500);
+```
+
+#### 4.3.4 Agent 分析回调
+
+```python
+# agents/frame_analyzer.py (新增)
+async def analyze_selected_frame(payload: dict, state: AgentState) -> dict:
+ """分析用户在 Perfetto UI 中选中的帧"""
+ ts_ns = int(payload['ts'])
+ dur_ns = int(payload['dur'])
+
+ # 1. 从 trace_processor 查询该帧的详细数据
+ tp = TraceProcessor(addr='localhost:9001')
+
+ # 查询该时间点的所有 slice
+ slices = tp.query(f"""
+ SELECT id, name, ts, dur, depth, track_id, cat
+ FROM slice
+ WHERE ts <= {ts_ns + dur_ns} AND ts + dur >= {ts_ns}
+ ORDER BY dur DESC
+ LIMIT 50
+ """).as_dict()['rows']
+
+ # 查询关联的 frame timeline
+ frames = tp.query(f"""
+ SELECT * FROM actual_frame_timeline_slice
+ WHERE ts <= {ts_ns + dur_ns} AND ts + dur >= {ts_ns}
+ """).as_dict()['rows']
+
+ # 查询调用链
+ call_chain = _build_call_chain(tp, slices[0]['id']) if slices else []
+
+ # 2. 构建分析上下文
+ frame_context = {
+ 'selected_slice': slices[0] if slices else None,
+ 'overlapping_slices': slices[1:20],
+ 'frame_timeline': frames,
+ 'call_chain': call_chain,
+ 'existing_perf_summary': state.get('perf_summary'),
+ }
+
+ # 3. 调用 LLM 分析(复用现有 analyzer prompt)
+ analysis = await _llm_analyze_frame(frame_context)
+
+ return {
+ 'type': 'frame_analysis',
+ 'slice': slices[0] if slices else None,
+ 'analysis': analysis,
+ 'suggestions': _generate_suggestions(frame_context),
+ }
+```
+
+### 4.4 用户交互流程
+
+```
+1. SI Agent 采集 trace -> 启动 trace_processor_shell HTTP 模式
+2. 自动打开浏览器 -> 桥接页面加载 -> iframe 嵌入 Perfetto UI
+3. Perfetto UI 自动连接 localhost:9001(native acceleration)
+4. 用户在 Perfetto UI 中浏览 trace,选中耗时帧
+5. 用户点击"分析此帧"按钮(或自动检测选中变化)
+6. 桥接页面通过 WebSocket 将 {ts, dur, track_id} 发送给 Agent
+7. Agent 通过 trace_processor HTTP API 查询该帧详细数据
+8. Agent 调用 LLM 分析(可复用现有 analyzer/attributor 能力)
+9. 分析结果通过 WebSocket 回传给桥接页面展示
+```
+
+## 五、与现有 Graph Pipeline 的集成可行性
+
+### 5.1 集成方式评估
+
+| 集成点 | 可行性 | 说明 |
+| --------------------------- | ------ | --------------------------------------------------------- |
+| 复用 PerfSummary | 5/5 | 帧分析可直接读取 `state['perf_summary']` 作为上下文 |
+| 复用 analyzer prompt | 4/5 | 现有 `prompts/perf_analysis.txt` 可适配帧级分析 |
+| 复用 attributor | 4/5 | `extract_attributable_slices()` + `run_attribution()` 可直接对选中帧归因 |
+| 复用 deterministic.py | 5/5 | `compute_hints()` 的子函数(severity、call chain)可直接复用 |
+| 新增 graph 节点 | 5/5 | LangGraph 架构支持新增 `frame_analyzer` 节点 |
+| 复用 trace_processor | 5/5 | HTTP 模式与 Python API 查询结果格式一致 |
+| 复用 WS 架构 | 4/5 | `SIServer` 可扩展,或独立 `BridgeServer` 并行运行 |
+
+### 5.2 推荐的 Graph 集成方案
+
+**不修改现有 pipeline,新增独立交互路径:**
+
+```python
+# state.py 扩展
+class AgentState(TypedDict):
+ # ... 现有字段 ...
+ selected_frame: dict | None # 新增:用户选中的帧信息 {ts, dur, track_id}
+ frame_analysis: str # 新增:帧分析结果
+
+# builder.py 扩展
+def create_graph():
+ # ... 现有节点 ...
+ builder.add_node("frame_analyzer", frame_analyzer_node)
+ # orchestrator 新增路由
+ # 或者:frame_analyzer 作为独立入口,不经过 orchestrator
+```
+
+**两种集成模式:**
+
+1. **对话式**:用户在 REPL 中说"分析我选中的帧",orchestrator 路由到 `frame_analyzer` 节点
+2. **实时式**:用户在 Perfetto UI 中点击,通过 WS 直接触发分析,结果推送到前端页面(不经过 LangGraph)
+
+**推荐 MVP 用模式 2(实时式)**,因为交互更自然。后续可扩展为模式 1 实现对话式帧分析。
+
+### 5.3 数据复用度分析
+
+```
+现有 Pipeline 数据 -> 帧分析可复用:
++-- perf_summary (全量) -> 作为帧分析的上下文背景
++-- view_slices.slowest -> 快速匹配选中帧
++-- frame_timeline.jank -> 判断选中帧是否为 jank 帧
++-- compute_hints() -> 复用 severity/classify 逻辑
++-- extract_attributable_slices() -> 复用归因逻辑
++-- attributor agent -> 复用源码搜索能力
++-- prompts/*.txt -> 复用/扩展分析 prompt
+```
+
+## 六、关键技术风险与应对
+
+| 风险 | 级别 | 应对方案 |
+| --------------------------------- | ---- | --------------------------------------------------------------------- |
+| Perfetto UI iframe 跨域限制 | 中 | 使用 `trace_processor_shell HTTP` 模式,Perfetto UI 自动连接本地服务 |
+| 无法直接获取 Perfetto UI 选中事件 | 高 | URL hash 轮询(MVP)-> MutationObserver(进阶)-> Fork + Plugin API(终极方案) |
+| trace_processor_shell HTTP 稳定性 | 低 | 官方支持的功能,Python API 底层就是用 HTTP 协议 |
+| 大 trace 文件加载性能 | 中 | HTTP 模式下 Perfetto UI 使用 native acceleration(WASM -> native) |
+| 桥接页面 UI 复杂度 | 中 | MVP 只做"选中+分析按钮+结果展示",后续迭代优化 |
+
+## 七、实现步骤(MVP)
+
+### Phase 1:基础设施(3 个文件改动 + 2 个新文件)
+
+1. **扩展 `collector/perfetto.py`**:新增 `TraceServer` 类,管理 `trace_processor_shell server http` 的生命周期
+2. **新增 `ws/bridge_server.py`**:aiohttp Web Server,提供桥接页面 + WebSocket 端点
+3. **新增 `ws/bridge.html`**(或内嵌在 bridge_server.py 中):桥接前端页面,嵌入 Perfetto UI iframe
+
+### Phase 2:帧分析核心(2 个新文件)
+
+4. **新增 `agents/frame_analyzer.py`**:接收帧选中信息,查询 trace_processor,调用 LLM 分析
+5. **新增 `graph/nodes/frame_analyzer.py`**(可选):如果需要集成到 LangGraph pipeline
+
+### Phase 3:端到端串联
+
+6. **修改 `graph/cli.py`**:采集 trace 后自动启动 TraceServer + 打开浏览器
+7. **修改 `commands/trace.py`**:新增 `/open` 命令,手动打开 Perfetto UI 桥接页面
+
+### Phase 4:体验优化
+
+8. 自动检测选中变化(MutationObserver)
+9. 分析结果面板美化(Markdown 渲染、源码高亮)
+10. 支持多次选中分析、分析历史
+
+## 八、插件系统深度调研(2026-04-15 补充)
+
+### 8.1 核心发现:必须 Fork
+
+Perfetto UI 插件 API 非常强大,但 **不支持外部加载**:
+
+> "All plugins are currently in-tree... There is no way, currently, to side-load closed-source plugins."
+
+插件位于 `ui/src/plugins/`,编译时打包。使用自定义插件只有两条路:
+1. **向上游贡献** — PR 到 `google/perfetto`,Apache-2.0 开源(SI Agent 场景不现实)
+2. **Fork + 自托管** — fork 仓库,添加自定义插件,构建部署(推荐)
+
+### 8.2 插件 API 能力
+
+| 扩展点 | API | 说明 |
+|--------|-----|------|
+| 自定义 Track | `trace.tracks.registerTrack()` | slice/counter track,支持 SQL 驱动 |
+| Tab 面板 | `trace.tabs.registerTab()` | 详情面板标签页,Mithril 渲染 |
+| 命令+快捷键 | `trace.commands.registerCommand()` | 命令面板操作 |
+| 区域选择 Tab | `trace.selection.registerAreaSelectionTab()` | 框选时间范围时显示自定义面板 |
+| Overlay | `trace.tracks.registerOverlay()` | 时间线上画箭头、标注 |
+| SQL 查询 | `trace.engine.query()` | 插件内执行 SQL |
+| 持久状态 | `trace.mountStore()` | permalink 安全的状态 |
+
+### 8.3 选中事件响应方式
+
+- `trace.selection.selection` 可读取当前选中状态
+- 无显式 `onSelectionChanged` 回调
+- **响应方式 1**:`registerAreaSelectionTab` — 用户框选区域时 Tab 的 `render()` 被调用,接收 `AreaSelection {start, end}`
+- **响应方式 2**:自定义 Track 的 `detailsPanel()` — 用户点击 slice 时展示自定义详情面板
+
+### 8.4 原方案 D 的跨域问题
+
+原方案 D(iframe 嵌入 Perfetto UI)存在 **跨域限制**:
+- Perfetto UI 在 `ui.perfetto.dev`,桥接页面在 `localhost`
+- 跨域 iframe 无法读取 `contentWindow.location.hash`
+- `MutationObserver` 无法访问跨域 `contentDocument`
+- URL hash 轮询策略在跨域场景下不可行
+
+### 8.5 修正方案:Fork + 自托管 + 插件
+
+由于插件 API 原生支持区域选择 Tab 和自定义命令,Fork + 自托管是最佳方案:
+
+```
+1. Fork google/perfetto
+2. 新建 com.smartinspector.Bridge 插件(~150 行 TS)
+3. 插件通过 WebSocket 连接 SI Agent
+4. 用户框选帧 → 点击分析 → WS 发送 ts/dur → Agent 分析 → 结果回传显示
+5. 构建静态文件 → 本地 HTTP Server 托管(同源,无跨域问题)
+```
+
+## 九、修正后的实施计划
+
+### Phase 1:命令行验证(已完成)
+
+- `/frame ts=X dur=Y` 命令,复用现有 REPL 架构
+- `query_frame_slices()` + `analyze_frame()` agent
+- 零前端开发,验证后端分析逻辑
+
+### Phase 2:Fork + 自托管 Perfetto UI 插件
+
+1. **创建 SI Bridge 插件** `perfetto-plugin/com.smartinspector.Bridge/index.ts`
+ - `registerAreaSelectionTab`: 用户框选帧 → 显示"分析"按钮 + 结果面板
+ - `registerCommand`: 快捷键 `Ctrl+Shift+A` 触发分析
+ - WebSocket 客户端连接 `ws://127.0.0.1:9877/bridge`
+2. **构建脚本** `perfetto-plugin/build.sh`:clone + 复制插件 + 构建
+
+### Phase 3:端到端串联
+
+3. **Bridge Server** `ws/bridge_server.py`:aiohttp 服务,端口 9877
+ - 托管 Perfetto UI 静态文件
+ - WebSocket `/bridge` 端点接收插件消息
+ - 调用 `frame_analyzer` agent 并回传结果
+4. **`/open` 命令**:启动 TraceServer + BridgeServer + 打开浏览器
+5. **自动启动**:`/trace` 完成后自动启动 TraceServer
+
+### Phase 4:体验优化(未来)
+
+6. 分析结果 Markdown 渲染
+7. 多次选中分析历史
+8. attributor 集成(源码定位直接显示在插件面板中)
+
+## 十、结论
+
+**可行性评估:可行,推荐 Fork + 自托管方案。**
+
+- **Phase 1(已完成)**:命令行 `/frame` 验证后端分析逻辑
+- **Phase 2**:Fork Perfetto + 自定义插件,原生 UI 集成质量最高
+- **Phase 3**:Bridge Server 端到端串联,`/open` 一键打开
+- **关键技术路径**:Perfetto 插件 API → WebSocket → SI Agent frame_analyzer → 结果回传
+- **最大优势**:插件 API 原生支持区域选择 Tab,用户交互自然流畅

+# SQL Summarizer & Analysis Verifier 设计文档
+
+> 基于 SmartPerfetto 对比分析,引入两个核心优化
+
+## 一、SQL Summarizer
+
+### 问题
+当前 `perf_analyzer.py` 和 `frame_analyzer.py` 直接将 SQL 查询结果(可能数千行)传给 LLM,导致:
+- Token 消耗高(一次分析可能 10k+ tokens)
+- LLM 在大量数据中容易遗漏关键信息或产生幻觉
+- 分析速度慢
+
+### 方案
+在 `deterministic.py` 中新增 `summarize_sql_result()` 函数,对 SQL 结果进行压缩:
+
+```python
+def summarize_sql_result(
+ rows: list[dict],
+ metric_col: str,
+ top_n: int = 10,
+ threshold_pct: float = 2.0,
+) -> str:
+ """将 SQL 查询结果压缩为统计摘要 + 异常采样。
+
+ Args:
+ rows: SQL 查询结果列表
+ metric_col: 用于统计的数值列名
+ top_n: 异常行采样数量
+ threshold_pct: 异常阈值(平均值的倍数)
+
+ Returns:
+ 压缩后的文本摘要
+ """
+```
+
+### 压缩策略
+1. **统计值**:count, min, max, avg, p95, p99(一行搞定)
+2. **分布直方图**:将值分桶(<16ms, 16-32ms, 32-64ms, >64ms),统计每桶数量
+3. **异常采样**:超过 avg * threshold_pct 的 top N 行
+4. **去重聚合**:相同 class.method 的多行聚合为一条(总耗时、调用次数)
+
+### 应用点
+1. `perf_analyzer.analyze_perf()` — perf_json 传入前压缩
+2. `frame_analyzer._build_frame_hints()` — frame_data 的 slices 列表压缩
+3. `frame_analyzer._run_source_attribution()` — attributable 列表压缩
+4. `deterministic.py` 的各分析函数中的数据预处理
+
+### 预期收益
+- Token 消耗降低 60-80%
+- LLM 分析速度提升 30%+
+- 减少幻觉(数据更聚焦)
+
+## 二、Analysis Verifier
+
+### 问题
+当前 SI 的 LLM 分析是单次调用,没有验证机制。分析结果可能:
+- 含糊其辞,没有具体数据支撑
+- 遗漏重要问题
+- 格式不统一
+
+### 方案
+在 `agents/` 下新增 `verifier.py`,实现分层验证:
+
+```python
+def verify_analysis(
+ analysis_text: str,
+ raw_hints: str,
+ expected_fields: list[str] = None,
+) -> VerificationResult:
+ """验证 LLM 分析结果的质量。
+
+ Returns:
+ VerificationResult(score, issues, passed)
+ """
+```
+
+### 验证层级(3层)
+
+#### L1: Heuristic Check(纯规则,0 token)
+- 结果是否包含具体数字(至少1个数值)
+- 结果是否包含具体方法名或类名(至少1个)
+- 结果长度是否合理(>100字符,<10000字符)
+- 是否包含 P0/P1/P2 分级
+
+#### L2: Consistency Check(纯规则,0 token)
+- L1 预计算结论中标记为 P0 的问题,分析结果中是否提及
+- L1 预计算结论中的关键数据点(如帧率、CPU使用率),分析结果中的数值是否一致(±20%)
+- 异常采样中的热点方法,分析结果中是否覆盖
+
+#### L3: Depth Check(可选,1次 LLM 调用)
+- 根因是否追溯到具体原因(而非"建议进一步排查")
+- 是否给出可操作的优化建议
+- 仅在 L2 不通过时触发
+
+### 验证结果处理
+- **L1+L2 全通过**:直接返回结果
+- **L2 不通过**:将缺失的关键信息和原始提示词重新组装,让 LLM 补充分析(最多1次重试)
+- **L1 不通过**:标记为低质量,返回结果但附带警告
+
+### 集成点
+1. `perf_analyzer.analyze_perf()` — 返回前调用 verify
+2. `frame_analyzer.analyze_frame()` — 返回前调用 verify
+3. `graph/nodes/reporter.py` — 报告生成前统一验证
+
+## 三、实施计划
+
+### Step 1: SQL Summarizer
+1. 在 `deterministic.py` 中实现 `summarize_sql_result()`
+2. 在 `perf_analyzer.py` 中集成:对 perf_json 中的 slices/block_events 列表应用压缩
+3. 在 `frame_analyzer.py` 中集成:对 frame_data 的 slices 和 attributable 列表应用压缩
+4. 测试:对比压缩前后的 token 消耗和 LLM 输出质量
+
+### Step 2: Analysis Verifier
+1. 新建 `agents/verifier.py`,实现 L1+L2 验证
+2. 在 `perf_analyzer.py` 和 `frame_analyzer.py` 中集成
+3. L3 暂不实现,作为后续优化项
+4. 测试:构造正常和异常的 LLM 输出,验证检测准确率
+
+### Step 3: 文档更新
+1. 更新 CLAUDE.md Commands 章节
+2. 更新 README.md 功能列表
+3. 更新 docs/architecture-improvement-spec.md
+
+## 四、设计约束
+- **不改变现有 API 接口**:`analyze_perf()` 和 `analyze_frame()` 的签名不变
+- **不引入新依赖**:纯 Python 实现,用标准库 statistics 模块
+- **向后兼容**:压缩和验证都是内部优化,对外透明
+- **遵循 LangGraph Pipeline Architecture Rule**:如果涉及图节点变更,复用现有链路

+# thread_state 阻塞原因分析 — 改造设计文档
+
+> 生成日期:2026-04-23
+> 状态:方案设计,待实施
+
+---
+
+## 一、问题背景
+
+### 1.1 当前 thread_state 的局限
+
+`collect_thread_state` 目前基于 `sched` 表手动推算线程状态分布:
+
+1. 计算 `sched` 表中与 slice 窗口重叠的 Running 时间
+2. 用 `slice_duration - running_time` 推算 blocked 时间
+3. 用最近的 `sched.end_state` 分类为 Sleeping 或 DiskSleep
+
+**问题**:只输出 `{Running: 100%}` 或 `{Sleeping: 100%}`,无法回答「为什么阻塞」。
+
+### 1.2 用户反馈
+
+> "thread_state 的作用是什么,我从报告中没有感受到"
+
+测试 trace 中所有 SI$ 慢切片都是 CPU 密集型(100% Running),thread_state 的结论与源码归因结论完全重复。即使遇到真正的阻塞切片,当前实现也只能给出笼统的 "Sleeping" 标签,无法提供可操作的优化建议。
+
+---
+
+## 二、Perfetto 中可用的阻塞详情数据
+
+通过实际查询 trace 文件,确认 `__intrinsic_thread_state` 表包含以下关键字段:
+
+| 字段 | 类型 | 说明 | 示例 |
+|------|------|------|------|
+| `state` | TEXT | 线程状态 | `Running`, `S`, `D`, `R+` |
+| `blocked_function` | TEXT | **内核阻塞函数名** | `folio_wait_bit_common` |
+| `io_wait` | INTEGER | **是否在等待IO** | `1` = IO等待 |
+| `waker_utid` | INTEGER | **唤醒者的线程ID** | 可关联 `thread.name` |
+| `irq_context` | INTEGER | 是否在中断上下文被唤醒 | `0`/`1` |
+| `ucpu` | INTEGER | 用户态CPU时间 | nanoseconds |
+
+### 2.1 实际数据验证
+
+以测试 trace(20s, com.smartinspector.hook)为例:
+
+**blocked_function 分布(跨所有线程):**
+
+| blocked_function | 含义 | 出现次数 | 总耗时 |
+|-----------------|------|---------|--------|
+| `worker_thread` | 工作线程等待 | 11177 | 745.5s |
+| `rcu_gp_fqs_loop` | RCU内核周期 | 3879 | 15.1s |
+| `msleep` | 内核主动睡眠 | 6 | 10.3s |
+| `sde_encoder_helper_wait_for_irq` | 等待显示硬件中断 | 1017 | 3.5s |
+| `_sde_encoder_cesta_update` | 显示编码器更新 | 1372 | 3.1s |
+| `spi_geni_transfer_one` | SPI总线传输(触控IC) | 489 | 633ms |
+| `folio_wait_bit_common` | **等待磁盘IO页缓存** | 1130 | 282ms |
+| `rpmh_write_batch` | 硬件资源电源管理 | — | — |
+
+**waker(唤醒关系):**
+
+| 唤醒者 | 被唤醒者 | 次数 |
+|--------|---------|------|
+| Jit thread pool | Profile Saver | 49286 |
+| swapper | TPP_MAIN | 10893 |
+| surfaceflinger | RelBufCB | 1957 |
+| tinspector.hook | logd.writer | 1794 |
+| TimerDispatch | app (主线程) | 1312 |
+| tinspector.hook | SI-BlockWatchdo | 1195 |
+
+**主线程 D 状态(DiskSleep):**
+```
+RenderThread: blocked_function=rpmh_write_batch (0.04ms)
+ → 等待硬件资源电源管理器完成写入
+```
+
+### 2.2 核心洞察
+
+当前 `collect_thread_state` 用 `sched` 表推算,**丢弃了 `blocked_function`、`waker_utid`、`io_wait` 三个关键字段**。改造后可以直接回答:
+
+- **为什么阻塞?** → `folio_wait_bit_common` = 等待磁盘IO页缓存
+- **阻塞了多久?** → 45ms
+- **谁唤醒的?** → `binder:1801_3` (Binder IPC 调用方)
+- **是IO等待吗?** → `io_wait=1` 确认
+
+---
+
+## 三、改造方案
+
+### 3.1 数据层:`collect_thread_state` 改用 `__intrinsic_thread_state`
+
+**位置**:`src/smartinspector/collector/perfetto.py` 的 `collect_thread_state()` 方法
+
+#### 当前实现(sched 推算)
+
+```python
+# 从 sched 表手动计算 Running 时间
+# blocked_time = slice_duration - running_time
+# 无法获取 blocked_function, waker, io_wait
+```
+
+#### 改造后实现
+
+```python
+def collect_thread_state(self) -> list[dict]:
+ tp = self._open()
+
+ # 获取主线程 utid
+ main_utid = self._resolve_main_utid(tp)
+ if main_utid is None:
+ return []
+
+ # 获取 SI$ 慢切片
+ slice_rows = tp.query("""
+ SELECT name, ts, dur
+ FROM slice
+ WHERE name LIKE 'SI$%'
+ AND name NOT LIKE 'SI$net#%'
+ AND name NOT LIKE 'SI$db#%'
+ AND dur > 1000000
+ ORDER BY dur DESC
+ LIMIT 20
+ """)
+
+ results = []
+ for sr in slice_rows:
+ slice_ts = sr.ts
+ slice_end = sr.ts + sr.dur
+ slice_name = sr.name
+ dur_ms = round(sr.dur / 1e6, 2)
+
+ # 查询 __intrinsic_thread_state 获取阻塞详情
+ state_rows = tp.query(f"""
+ SELECT
+ state,
+ SUM(dur) AS total_ns,
+ blocked_function,
+ io_wait,
+ waker_utid,
+ CASE WHEN waker_utid IS NOT NULL
+ THEN (SELECT name FROM thread WHERE utid = waker_utid)
+ ELSE NULL END AS waker_name
+ FROM __intrinsic_thread_state
+ WHERE utid = {main_utid}
+ AND ts < {slice_end}
+ AND ts + dur > {slice_ts}
+ GROUP BY state, blocked_function, io_wait, waker_utid
+ ORDER BY total_ns DESC
+ """)
+
+ # 如果没有 thread_state 覆盖,推断为 Running
+ # (sleeping 线程无法执行产生 slice 的代码)
+ state_entries = list(state_rows)
+ if not state_entries:
+ results.append({
+ "slice_name": slice_name,
+ "dur_ms": dur_ms,
+ "state_distribution": {"Running": 100.0},
+ "dominant_state": "Running",
+ "blocked_function": None,
+ "io_wait": False,
+ "waker_name": None,
+ })
+ continue
+
+ total_ns = sum(r.total_ns for r in state_entries)
+ pct_dist = {}
+ blocked_fn = None
+ io_wait = False
+ waker_name = None
+
+ for r in state_entries:
+ # 映射状态名
+ state_label = _map_state_label(r.state)
+ pct = round(r.total_ns / total_ns * 100, 1)
+ pct_dist[state_label] = pct_dist.get(state_label, 0) + pct
+
+ # 记录第一个非 Running 状态的阻塞详情
+ if state_label != "Running" and blocked_fn is None:
+ blocked_fn = r.blocked_function
+ io_wait = bool(r.io_wait)
+ waker_name = r.waker_name
+
+ dominant = max(pct_dist, key=pct_dist.get)
+ results.append({
+ "slice_name": slice_name,
+ "dur_ms": dur_ms,
+ "state_distribution": pct_dist,
+ "dominant_state": dominant,
+ "blocked_function": blocked_fn,
+ "io_wait": io_wait,
+ "waker_name": waker_name,
+ })
+
+ return results
+```
+
+#### 状态映射函数
+
+```python
+def _map_state_label(raw_state: str) -> str:
+ """Map kernel thread state to human-readable label."""
+ mapping = {
+ "Running": "Running",
+ "R": "Running",
+ "R+": "Running",
+ "S": "Sleeping",
+ "D": "DiskSleep",
+ "D+": "DiskSleep",
+ "T": "Stopped",
+ "t": "Traced",
+ "X": "Dead",
+ "Z": "Zombie",
+ }
+ return mapping.get(raw_state, raw_state)
+```
+
+#### 新增返回字段
+
+```python
+{
+ "slice_name": "SI$RV#...",
+ "dur_ms": 73.0,
+ "state_distribution": {"Running": 80.0, "Sleeping": 20.0},
+ "dominant_state": "Running",
+ # ↓ 新增字段
+ "blocked_function": "futex_wait_queue_me", # 阻塞的内核函数
+ "io_wait": False, # 是否IO等待
+ "waker_name": "WorkerThread-2", # 谁唤醒了此线程
+}
+```
+
+### 3.2 预计算层:`_analyze_thread_state` 增加阻塞原因解读
+
+**位置**:`src/smartinspector/agents/deterministic.py` 的 `_analyze_thread_state()`
+
+#### 改造内容
+
+在现有 Running/Sleeping/DiskSleep 分类基础上,增加 `blocked_function` 解读:
+
+```python
+# blocked_function 到人类可读原因的映射
+BLOCKED_FN_MEANING = {
+ "futex_wait_queue_me": "等待锁释放 (futex)",
+ "futex_wait": "等待锁释放 (futex)",
+ "folio_wait_bit_common": "等待磁盘IO (页缓存)",
+ "wait_woken": "等待被唤醒",
+ "msleep": "内核主动睡眠",
+ "rpmh_write_batch": "等待硬件资源电源管理",
+ "sde_encoder_helper_wait_for_irq": "等待显示硬件中断",
+ "spi_geni_transfer_one": "等待SPI总线传输",
+ "do_writepages": "等待磁盘写入",
+ "journal_commit": "等待文件系统日志提交",
+ "bio_wait": "等待块IO完成",
+ "pipe_wait": "等待管道数据",
+ "unix_stream_recvmsg": "等待Unix Socket数据",
+ " binder_thread_read": "等待Binder IPC回复",
+}
+
+IO_WAIT_MEANING = {
+ True: "IO等待 (磁盘/网络/设备)",
+ False: "", # 非IO等待时省略
+}
+```
+
+#### 输出格式
+
+**阻塞切片(Sleeping/DiskSleep 主导):**
+
+```
+[线程状态分析]
+ 以下切片主要处于阻塞状态:
+
+ SharedPreferencesImpl.awaitLoadedLocked (45.2ms):
+ Sleeping 100% | 原因: futex_wait_queue_me (等待锁释放)
+ 唤醒者: main
+
+ SQLiteDatabase.query (120.5ms):
+ DiskSleep 85%, Running 15% | 原因: folio_wait_bit_common (等待磁盘IO)
+ IO等待: 是 | 唤醒者: binder:1801_3
+```
+
+**Running 切片(不变,但补充「无阻塞」说明):**
+
+```
+ 以下切片主要在执行用户代码(无IO/锁阻塞):
+
+ DemoAdapter.onBindViewHolder (73.0ms): Running 100%
+ CpuBurnWorker.startMainThreadWork (129.0ms): Running 100%
+```
+
+### 3.3 报告格式层:`format_perf_sections` 增加阻塞详情展示
+
+**位置**:`src/smartinspector/graph/nodes/reporter/formatter.py` 的 `format_perf_sections()`
+
+#### 改造内容
+
+```python
+thread_states = perf_data.get("thread_state", [])
+if thread_states:
+ ts_lines = ["## 线程状态分析\n"]
+ ts_lines.append("区分\"代码慢\"(Running)和\"被阻塞\"(Sleeping/DiskSleep):")
+
+ # 分两组展示:先阻塞,后 Running
+ blocked = [ts for ts in thread_states
+ if ts.get("dominant_state") in ("Sleeping", "DiskSleep")]
+ running = [ts for ts in thread_states
+ if ts.get("dominant_state") == "Running"]
+
+ if blocked:
+ ts_lines.append("")
+ ts_lines.append("**阻塞切片**(线程被IO/锁挂起,优化方向不是代码本身):")
+ for ts in blocked[:5]:
+ short = ts["slice_name"].replace("SI$", "")
+ dist_str = ", ".join(f"{k} {v:.0f}%" for k, v in ts["state_distribution"].items())
+ ts_lines.append(f"- {short} ({ts['dur_ms']:.1f}ms): {dist_str}")
+ # 新增:阻塞原因
+ bf = ts.get("blocked_function")
+ if bf:
+ meaning = BLOCKED_FN_MEANING.get(bf, bf)

+ if running:
+ ts_lines.append("")
+ ts_lines.append("**Running切片**(代码执行慢,需优化算法或异步化):")
+ for ts in running[:5]:
+ short = ts["slice_name"].replace("SI$", "")
+ ts_lines.append(f"- {short} ({ts['dur_ms']:.1f}ms): Running 100%")
+
+ user_parts.append("\n".join(ts_lines))
+```
+
+### 3.4 报告生成层:LLM Prompt 增加 blocked_function 上下文
+
+**位置**:`src/smartinspector/graph/nodes/reporter/` 的 prompt 模板
+
+在预计算结论 section 中,blocked_function 信息将帮助 LLM 生成**针对性的建议**,而非模板化建议:
+
+| blocked_function | LLM 应生成的建议 |
+|-----------------|----------------|
+| `futex_wait_queue_me` | 「主线程在等待锁释放,检查是否有后台线程持有锁(如 SharedPreferences 同步提交)」 |
+| `folio_wait_bit_common` | 「等待磁盘IO完成,考虑使用异步IO或增加缓存命中率」 |
+| `binder_thread_read` | 「等待 Binder IPC 回复,考虑将同步 Binder 调用改为异步」 |
+| `spi_geni_transfer_one` | 「等待SPI总线传输(通常为触控IC),属于硬件瓶颈,应用层无法优化」 |
+| `NULL` + Running 100% | 「代码执行慢,需优化算法复杂度或将耗时操作移至后台线程」 |
+
+---
+
+## 四、涉及文件清单
+
+| 文件 | 改动类型 | 说明 |
+|------|---------|------|
+| `src/smartinspector/collector/perfetto.py` | **重写** | `collect_thread_state` 改用 `__intrinsic_thread_state` 表 |
+| `src/smartinspector/agents/deterministic.py` | **增强** | `_analyze_thread_state` 增加 `blocked_function` 解读和分组展示 |
+| `src/smartinspector/graph/nodes/reporter/formatter.py` | **增强** | `format_perf_sections` 展示阻塞原因、IO等待、唤醒者 |
+| `src/smartinspector/graph/nodes/reporter/prompts.py` | **微调** | Reporter prompt 增加阻塞原因相关的分析指引(可选) |
+
+---
+
+## 五、降级策略
+
+`__intrinsic_thread_state` 表可能在某些 Perfetto 版本中不可用。需要 fallback:
+
+```python
+# 1. 先尝试 __intrinsic_thread_state
+try:
+ state_rows = tp.query("SELECT 1 FROM __intrinsic_thread_state LIMIT 1")
+ has_intrinsic_ts = True
+except:
+ has_intrinsic_ts = False
+
+# 2. 如果不可用,回退到当前 sched 推算逻辑(保持现有行为)
+if not has_intrinsic_ts:
+ return self._collect_thread_state_fallback()
+```
+
+---
+
+## 六、预期效果
+
+### 改造前报告
+
+```
+### P0 [DemoAdapter.onBindViewHolder]
+
+现象:onBindViewHolder 耗时 73ms。
+
+原因:同步解码 Bitmap 导致主线程阻塞。
+
+建议:
+1. 使用异步图片加载库
+2. 在后台线程预解码
+3. 增大缓存容量
+```
+
+→ 所有建议都是模板化的「通用优化方案」,无法区分问题类型。
+
+### 改造后报告
+
+**场景 A:Running 100%(代码慢)**
+
+```
+### P0 [DemoAdapter.onBindViewHolder]
+
+现象:onBindViewHolder 耗时 73ms。
+线程状态:Running 100%(纯代码执行,无IO/锁阻塞)
+
+原因:BitmapFactory.decodeResource 同步解码 200x200 图片,在主线程执行IO密集操作。
+虽然 thread_state 显示 Running,但 decodeResource 底层调用了磁盘读取,
+只是因为读取速度快未触发 D 状态。建议改用异步图片加载库。
+
+建议:
+1. 使用 Coil/Glide 异步加载,主线程只负责设置 placeholder
+2. 增大 bitmapCache 容量至可见 item 数量的 2 倍
+```
+
+**场景 B:Sleeping 主导(锁等待)— 改造后新增的识别能力**
+
+```
+### P0 [SharedPreferencesImpl.awaitLoadedLocked]
+
+现象:awaitLoadedLocked 耗时 45ms。
+线程状态:Sleeping 100%
+阻塞原因:futex_wait_queue_me(等待锁释放)
+唤醒者:SharedPreferencesImpl.writeThread
+
+原因:主线程在 awaitLoadedLocked 中通过 futex 等待 SharedPreferences 文件加载完成。
+writeThread 在后台加载 XML 文件,但主线程的 getSharedPreferences() 调用发起了同步等待。
+在启动阶段,如果 SP 文件较大(>100KB),这个等待可能超过一帧(16ms)。
+
+建议:
+1. 使用 commit() 替代 apply() 避免阻塞(已废弃)
+2. 将 SP 读取移到 Application.onCreate 之前(Multidex 期间并行加载)
+3. 考虑迁移到 DataStore(基于 Protocol Buffer,支持异步)
+```
+
+**场景 C:DiskSleep 主导(磁盘IO)— 改造后新增的识别能力**
+
+```
+### P0 [SQLiteDatabase.query]
+
+现象:query 耗时 120ms。
+线程状态:DiskSleep 85%, Running 15%
+阻塞原因:folio_wait_bit_common(等待磁盘IO页缓存)
+IO等待:是
+唤醒者:kworker/2:1
+
+原因:SQL 查询触发了磁盘页缓存缺失,需要从闪存读取数据。
+120ms 中 102ms 花在等待磁盘IO,仅 18ms 在执行查询逻辑。
+属于磁盘IO瓶颈而非查询语句效率问题。
+
+建议:
+1. 增加 WAL 模式的 checkpoint 频率,减少读阻塞
+2. 对热点表建立索引减少扫描量
+3. 考虑使用 Room 的分页查询(Paging 3)避免一次加载过多数据
+```
+
+---
+
+## 七、实施计划
+
+| 步骤 | 内容 | 预计改动量 |
+|------|------|-----------|
+| 1 | `perfetto.py` 重写 `collect_thread_state`,新增 `_map_state_label` | ~80 行 |
+| 2 | `deterministic.py` 增强 `_analyze_thread_state`,新增 `BLOCKED_FN_MEANING` 映射 | ~40 行 |
+| 3 | `formatter.py` 增强 thread_state 展示,增加阻塞原因/IO等待/唤醒者 | ~25 行 |
+| 4 | 添加 fallback 逻辑(`__intrinsic_thread_state` 不可用时回退到 sched 推算) | ~15 行 |
+| 5 | 用现有 trace 验证 Running 100% 场景不变,验证降级逻辑 | 测试 |
+| 6 | 构造 Sleeping/DiskSleep 测试场景验证新增数据路径 | 测试 |

+### 1.3 关键差距(基于代码分析)
+
+#### A. Android Hook 层差距
+
+1. **IO hooks 虽已实现但未启用且未经测试** ~~→ ✅ P0-1 已修复:默认开启,Python 端 IO 切片收集和归因已实现~~
+2. **无 Compose 支持**:Jetpack Compose 的重组(recomposition)追踪完全缺失,而 Compose 已是 Android UI 主流。
+3. **无 Coroutine 追踪**:协程的线程切换和挂起无法追踪。
+4. **无冷启动专项分析** ~~→ ✅ P0-2 已修复:`collector/startup.py` + `graph/nodes/startup.py` 已实现~~
+5. **ExtraHook 参数推断简陋**:`hookExtraClasses()` 只尝试无参签名(`TraceHook.java:782-783`),无法精确匹配方法参数。
+6. **无 GPU 渲染分析**:`HookConfig.collectGpuMem` 默认关闭,无 GPU pipeline 追踪。
+
+#### B. Python 分析管线差距
+
+7. **无内存分配追踪**:`PerfSummary` 有 `memory` 字段但 `summarize()` 中未实现 `collect_memory()` — 只采集了 RSS 计数器,无对象级分配分析。
+8. **IO slices 未纳入归因** ~~→ ✅ P0-5 已修复:IO 切片归因已实现,`commands/attribution.py` 支持 SI$net#/SI$db#/SI$img# 解析~~
+9. **无跨进程分析**:`_resolve_target_process()` 只关注单进程(`perfetto.py:92-173`),无法分析多进程交互。
+10. **headless/CI 模式缺失** ~~→ ✅ P0-3 已修复:`headless.py` + `--ci` CLI 参数已实现~~
+11. **报告仅 Markdown** ~~→ ✅ P0-4 已修复:`json_formatter.py` 已实现 JSON 格式输出~~
+12. **无历史对比**:多次分析结果无法对比趋势。
+
+#### C. 开发者体验差距
+
+13. **一键分析不够简单**:需要 5+ 步才能完成一次完整分析(连设备 → 启动 app → 采集 trace → 分析 → 查看报告)。
+14. **配置管理分散**:Android 端 `SharedPreferences`、CLI 端环境变量、WS 协议三套配置。
+15. **错误恢复差**:`node_error_handler` 只捕获异常返回错误消息,不重试。
+

+
+---
+
+## 3. P0 详细设计
+
+### 3.1 P0-1: IO Hooks 验证与启用
+
+**现状**:`TraceHook.java` 中 `hookNetworkIo()` (L632)、`hookDatabaseIo()` (L659)、`hookImageLoad()` (L709) 已完整实现,Python 端 `collect_io_slices()` (L977) 已有查询。只是 `HookConfig` 默认关闭且未经集成测试。
+
+**变更清单**:
+
+```
+platform/android/tracelib/src/main/java/com/smartinspector/tracelib/HookConfig.java
+ - networkIo: false → true
+ - databaseIo: false → true
+ - imageLoad: false → true
+
+src/smartinspector/commands/attribution.py
+ - extract_attributable_slices() 增加对 SI$net#/SI$db#/SI$img# 的解析
+
+src/smartinspector/agents/deterministic.py
+ - 新增 _analyze_io_slices() helper
+ - 对 IO 切片按类型分类统计 + 按耗时排序
+
+src/smartinspector/graph/nodes/reporter/formatter.py
+ - IO 分析结果格式化为报告章节
+```
+
+**验证方式**:
+1. Demo App 增加 IO 场景(网络请求、数据库读写、图片加载)
+2. `/full` 分析验证 IO slices 出现在报告中
+3. 确认 IO hooks 对主线程 ANR 无影响
+
+### 3.2 P0-2: 冷启动专项分析模式
+
+**现状**:`orchestrator.py:104-113` 已检测冷启动关键词并设置 `skip_wait=True`。但缺少:
+- 启动阶段自动切分(pre-main → main → first-frame → full-frame)
+- Application.onCreate 追踪(已 hook `TraceHook.java:263-278`,但无下游分析)
+- 启动链路可视化
+
+**设计**:
+
+```python
+# 新增 collector/startup.py
+
+class StartupAnalyzer:
+ """冷启动分析器:从 trace 中提取启动链路"""
+
+ def analyze_cold_start(self, collector: PerfettoCollector) -> StartupResult:
+ # Phase 1: 定位 app 进程启动时间
+ # SELECT MIN(ts) FROM process_track WHERE ...
+ # 或 package_list 表中 uid 首次出现
+
+ # Phase 2: 切分启动阶段
+ # pre_main: fork → Application.attachBaseContext
+ # init: Application.onCreate → Activity.onCreate
+ # first_frame: Activity.onCreate → 首帧 doFrame
+ # full_draw: 首帧 → 首帧完成后绘制完毕
+
+ # Phase 3: 每个阶段的 SI$ 切片聚合
+ # 与 view_slices 查询复用,按时间窗口过滤
+
+ # Phase 4: 关键路径提取
+ # 主线程上 dur 最长的切片链
+```
+
+**CLI 集成**:
+```
+用户输入: "分析冷启动" / "分析启动耗时"
+→ orchestrator → collector (skip_wait=True, duration=15s)
+ → startup_analyzer → 报告
+```
+
+**报告输出格式**:
+```markdown
+## 冷启动分析
+
+总耗时: 1.23s
+
+| 阶段 | 耗时 | 占比 |
+|------|------|------|
+| pre-main (进程启动) | 120ms | 10% |
+| Application.onCreate | 350ms | 28% |
+| Activity.onCreate → 首帧 | 580ms | 47% |
+| 首帧渲染完成 | 180ms | 15% |
+
+### 关键瓶颈
+1. **Application.onCreate (350ms)**
+ - DataRepository.initialize: 200ms (SI$inflate#splash_layout)
+ - ...
+
+### 优化建议
+- 延迟初始化: DataRepository.initialize 可移至后台线程
+- 布局优化: splash_layout 层级过深 (4 层 LinearLayout)
+```
+
+### 3.3 P0-3: Headless/CI 模式
+
+**设计**:
+
+```bash
+# 非交互模式
+smartinspector --ci \
+ --target com.example.app \
+ --duration 10000 \
+ --source-dir /path/to/source \
+ --output reports/report.json \
+ --format json
+
+# 分析已有 trace
+smartinspector --ci \
+ --trace /path/to/trace.pb \
+ --source-dir /path/to/source \
+ --output reports/report.md \
+ --format markdown
+```
+
+**新增文件**:
+```
+src/smartinspector/headless.py # HeadlessRunner 类
+src/smartinspector/commands/quick.py # /quick 命令实现
+```
+
+**核心逻辑**:
+```python
+class HeadlessRunner:
+ """非交互式分析运行器,跳过 REPL 直接执行完整管线"""
+
+ def run(self, trace_path: str = None,
+ collect: bool = True, target: str = None,
+ source_dir: str = ".", output: str = None,
+ format: str = "markdown") -> str:
+
+ if collect:
+ trace_path = PerfettoCollector.pull_trace_from_device(...)
+ collector = PerfettoCollector(trace_path, target_process=target)
+ summary = collector.summarize()
+
+ # 确定性分析
+ hints = compute_hints(summary.to_json())
+
+ # LLM 分析
+ analysis = analyze_perf(summary.to_json())
+
+ # 源码归因
+ attribution = run_attribution(attributable_slices)
+
+ # 生成报告
+ if format == "json":
+ report = format_json(summary, analysis, attribution)
+ else:
+ report = format_markdown(summary, analysis, attribution)
+
+ if output:
+ Path(output).write_text(report)
+ return report
+```
+
+### 3.4 P0-4: JSON 报告格式
+
+**Schema 设计**:
+
+```json
+{
+ "version": "1.0",
+ "timestamp": "2026-04-24T10:30:00Z",
+ "target": {
+ "package": "com.example.app",

+ "cpu_hotspots": [ ... ],
+ "thread_state": [ ... ],
+ "io_slices": { ... },
+ "memory": { ... }
+ }
+}
+```
+
+### 3.5 P0-5: IO Slices 归因
+
+**变更点**:
+
+在 `commands/attribution.py` 的 `extract_attributable_slices()` 中增加 IO 切片解析:
+
+```python
+# 现有: 只处理 SI$ 开头且排除 SI$net#/SI$db#/SI$img#
+# 变更: 对 IO 切片也进行类名/方法名提取和归因
+
+def _parse_io_slice_name(name: str) -> dict:
+ """解析 IO slice 名称为 class.method
+
+ SI$net#okhttp3.internal.connection.RealCall.execute
+ SI$db#com.example.data.DatabaseHelper.query#users
+ SI$img#com.bumptech.glide.request.RequestBuilder.into
+ """
+ # 去掉 SI$prefix# 得到 FQN
+ for prefix in ("SI$net#", "SI$db#", "SI$img#"):
+ if name.startswith(prefix):
+ body = name[len(prefix):]
+ # 可能有 #table 后缀 (DB query)
+ parts = body.split("#")
+ fqn = parts[0]
+ # 解析 class.method
+ if "." in fqn:
+ last_dot = fqn.rfind(".")
+ return {
+ "class_name": fqn[:last_dot],
+ "method_name": fqn[last_dot+1:],
+ "io_type": prefix[3:-1], # "net"/"db"/"img"
+ }
+ return None
+```
+
+在 `agents/deterministic.py` 新增 `_analyze_io_slices()`:
+
+```python
+def _analyze_io_slices(data: dict) -> str:
+ """分析 IO 切片:按类型聚合,标记主线程 IO"""
+ io_slices = data.get("io_slices") or {}
+ if not io_slices:
+ return ""
+
+ summary = io_slices.get("summary") or []
+ lines = ["[IO 分析]"]
+
+ # 按类型聚合
+ by_type = {}
+ for s in summary:
+ io_type = s.get("io_type", "unknown")
+ if io_type not in by_type:
+ by_type[io_type] = {"count": 0, "total_ms": 0, "max_ms": 0, "items": []}
+ by_type[io_type]["count"] += s["count"]
+ by_type[io_type]["total_ms"] += s["total_ms"]
+ by_type[io_type]["max_ms"] = max(by_type[io_type]["max_ms"], s["max_ms"])
+ by_type[io_type]["items"].append(s)
+
+ for io_type, stats in sorted(by_type.items(), key=lambda x: -x[1]["total_ms"]):

+ f"总耗时{stats['total_ms']:.1f}ms, "
+ f"最大{stats['max_ms']:.1f}ms"
+ )
+
+ return "\n".join(lines)
+```
+
+---
+
+## 4. P1 详细设计
+
+### 4.1 P1-1: Compose 重组追踪
+
+**技术方案**:
+
+Compose 编译器会在编译期为每个可组合函数生成代码,并使用 `Composer` 进行追踪。Android 已在 `androidx.compose.runtime` 中提供了 `TraceInformation` 接口(API 31+)。
+
+**Hook 方案**:
+
+```kotlin
+// 新增 ComposeHook.kt
+object ComposeHook {
+
+ fun hook() {
+ // 方案 A: Hook ComposeRuntime 的 trace 系统
+ // compose.runtime.internal.TracerImpl.begin / end
+ try {
+ val tracer = Class.forName(
+ "androidx.compose.runtime.internal.TracerImpl"
+ )
+ safeHookMethod(tracer, "beginSection", ...)
+ safeHookMethod(tracer, "endSection", ...)
+ } catch (e: Exception) {
+ // Fallback: 方案 B
+ }
+
+ // 方案 B: Hook Compose 的 remember 和 recompose
+ // 追踪每个 Composable 的调用次数和耗时
+ try {
+ val composer = Class.forName(
+ "androidx.compose.runtime.ComposerImpl"
+ )
+ // startRestartGroup / endRestartGroup
+ safeHookMethod(composer, "startRestartGroup", ...)
+ } catch (e: Exception) {
+ Log.w(TAG, "Compose hook failed: ${e.message}")
+ }
+ }
+}
+```
+
+**Perfetto 集成**:
+- 切片前缀:`SI$compose#`
+- Tag 格式:`SI$compose#ComposableName#recompose` / `SI$compose#ComposableName#first`
+- 下游 Python 端新增 `collect_compose_slices()` 查询
+
+### 4.2 P1-2: 内存分配分析
+
+**现状**:`PerfettoCollector` 已采集 `collectJavaHeap=true`(在 Perfetto 配置中),但 `summarize()` 中 `memory` 字段只从 `process_counter_track` 获取 RSS,未利用 `heap_graph` 表。
+
+**新增分析**:
+
+```python
+def collect_memory(self, target_upid: int) -> dict:
+ """分析 Java 堆内存分配和对象分布"""
+ tp = self._open()
+
+ # 1. Java 堆对象统计 (heap_graph)
+ # 按类名聚合对象数量和总大小
+ heap_stats = tp.query("""
+ SELECT
+ o.type_name,
+ COUNT(*) AS obj_count,
+ SUM(o.self_size) AS total_size
+ FROM heap_graph_object o
+ JOIN heap_graph_class c ON o.type_name = c.name
+ WHERE o.upid = {upid}
+ AND o.reachable = 1

+### 回归项
+- DemoAdapter.onBindViewHolder: 15ms → 20ms (+33%) ⚠️
+
+### 改善项
+- MainThread IO: 80ms → 10ms (-87%) ✓
+```
+
+### 4.4 P1-4: 智能一键分析
+
+**目标**:`/quick` 命令,30 秒内完成轻量分析,不需要 LLM 调用。
+
+```python
+# commands/quick.py
+
+def quick_analysis(trace_path: str, source_dir: str) -> str:
+ """快速分析:纯确定性,不调用 LLM"""
+ collector = PerfettoCollector(trace_path)
+ summary = collector.summarize()
+ hints = compute_hints(summary.to_json())
+
+ # 运行归因 (fast path only)
+ attributable = extract_attributable_slices(...)
+ results = run_attribution(attributable) # 只用 fast path
+
+ # 拼接报告
+ return format_quick_report(hints, results)
+```
+
+### 4.5 P1-5: ExtraHook 参数自动推断
+
+**现状**:`hookExtraClasses()` 只尝试无参签名。
+
+**改进**:
+
+```java
+private static void hookExtraClasses() {
+ for (ExtraHook eh : HookConfigManager.getExtraHooks()) {
+ try {
+ Class> clazz = Class.forName(eh.className);
+ for (String methodName : eh.methods) {
+ // 自动推断所有可能的重载签名
+ for (Method m : clazz.getDeclaredMethods()) {
+ if (m.getName().equals(methodName)) {
+ Pine.hook(m, new MethodHook() { ... });
+ }
+ }
+ }
+ } catch (Exception e) {
+ Log.w(TAG, "Extra hook failed: " + e.getMessage());
+ }
+ }
+}
+```
+
+---
+
+## 5. 架构改进
+
+### 5.1 配置统一
+
+**现状**:三套配置系统
+- Android: `SharedPreferences` + `HookConfig` JSON
+- CLI: 环境变量 + `config.py` 全局变量
+- WS 协议: `config_sync` / `config_update` 消息
+
+**改进方案**:引入统一配置文件 `si.yaml`
+
+```yaml
+# si.yaml - 项目级配置
+android:
+ hooks:
+ network_io: true
+ database_io: true
+ perfetto:
+ duration_ms: 10000
+ buffer_size_kb: 65536
+ cpu_sampling_interval_ms: 1
+
+analysis:
+ source_dir: "./src"
+ frame_budget_ms: 16.67 # 0 = auto detect
+ jank_threshold_ms: 16.0
+
+llm:
+ model: "deepseek-chat"
+ base_url: "https://api.deepseek.com"
+ # api_key from env SI_API_KEY
+
+output:
+ format: "markdown" # markdown | json
+ reports_dir: "./reports"
+```
+
+CLI 和 Android 端都从这份配置同步。
+
+### 5.2 错误恢复增强
+
+**现状**:`node_error_handler` 只捕获异常,返回错误消息。
+
+**改进**:
+
+```python
+def node_error_handler(node_name: str, retry: int = 0):
+ def decorator(func):
+ @functools.wraps(func)
+ def wrapper(state):
+ last_error = None
+ for attempt in range(retry + 1):
+ try:
+ return func(state)
+ except Exception as e:
+ last_error = e
+ if attempt < retry:
+ print(f" [{node_name}] retry {attempt+1}/{retry}...", flush=True)
+ # All retries failed
+ return {
+ "messages": [AIMessage(content=f"[{node_name}] Error: {last_error}")],
+ **_pass_through(state),
+ }
+ return wrapper
+ return decorator
+```
+
+### 5.3 Collector 拆分
+
+**现状**:`collector/perfetto.py` 是 1340+ 行的大文件。
+
+**拆分方案**:
+
+```
+collector/
+ __init__.py
+ perfetto.py # PerfettoCollector 核心 (trace 加载, summarize)
+ queries/
+ __init__.py
+ frame_timeline.py # collect_frame_timeline()
+ cpu_hotspots.py # collect_cpu_hotspots(), collect_cpu_usage()
+ view_slices.py # collect_view_slices(), collect_io_slices()
+ thread_state.py # collect_thread_state()
+ block_events.py # collect_block_events()
+ memory.py # collect_memory() (P1-2)
+ startup.py # StartupAnalyzer (P0-2)
+ input_events.py # collect_input_events()
+ scheduling.py # collect_sched()
+ trace_server.py # TraceServer
+ device.py # pull_trace_from_device(), adb 操作
+```
+

+
+## 6. 贡献者指南
+
+### 6.1 如何贡献
+
+每个 P0/P1 任务都是独立的 PR 单元,贡献者可以:
+
+1. 从 issue 列表中认领任务
+2. 在对应分支上开发(`feat/p0-io-hooks`, `feat/p0-startup`, etc.)
+3. 确保通过 `pytest tests/` 测试
+4. Demo App 场景验证
+5. 提交 PR + 填写 PR 模板
+
+### 6.2 代码规范
+
+- **Python**: 类型注解 + docstring,`debug_log()` 用于数据检查日志
+- **Java/Kotlin**: `SI$` 前缀标签,`shortenFqn()` 处理 127 字符限制
+- **SQL**: 查询放在 `collector/queries/` 独立文件中
+- **LLM prompt**: 放在 `prompts/` 目录,使用 `load_prompt()` 加载
+
+### 6.3 测试要求
+
+- 每个 P0 变更需要同步更新 Demo App 场景
+- Python 测试使用 synthetic trace(参考 `tests/` 现有模式)
+- Android 测试:Demo App 手动验证 + 截图
+

+## 4. P2-6 详细设计:源码归因增强(借鉴 claude-context)
+
+### 背景
+参考 [zilliztech/claude-context](https://github.com/zilliztech/claude-context) 的设计,提升SI项目源码归因的搜索效率和精度。
+
+### 当前问题
+1. **无文件过滤**:搜索全目录,包含build/vendor/node_modules等无关文件
+2. **按文件搜索**:搜索结果粒度为整个文件,无法精确到函数/类级别
+3. **大项目慢**:grep在100+文件项目中效率低
+4. **无模糊匹配**:方法名不完全匹配时(如混淆代码)搜索失败
+
+### 改进方案
+
+#### 1. .gitignore 文件过滤
+```python
+# commands/attribution.py 或新建 source_search.py
+import pathspec
+
+def load_gitignore(source_dir: str) -> pathspec.PathSpec:
+ gitignore_path = os.path.join(source_dir, '.gitignore')
+ if os.path.exists(gitignore_path):
+ with open(gitignore_path) as f:
+ return pathspec.PathSpec.from_lines('gitwildmatch', f)
+ return pathspec.PathSpec.from_lines('gitwildmatch', [])
+
+def should_ignore(path: str, spec: pathspec.PathSpec) -> bool:
+ return spec.match_file(path)
+```
+
+#### 2. 函数级分块
+```python
+# 基于 AST 或正则的轻量分块
+import re
+
+def chunk_by_function(source: str) -> list[dict]:
+ \"\"\"将源码按函数/类切分为块,每块带行号范围。\"\"\"
+ chunks = []
+ # 匹配函数/类定义
+ pattern = re.compile(r'^(class |def |public |private |protected |@\\w+).*$', re.MULTILINE)
+ ...
+ return chunks
+```
+
+#### 3. 轻量BM25索引(可选)
+```python
+# 对大项目(>100文件)预建索引
+from rank_bm25 import BM25Okapi
+
+class SourceIndex:
+ def __init__(self, source_dir: str):
+ self.chunks = self._index_source(source_dir)
+ self.bm25 = BM25Okapi([c['tokens'] for c in self.chunks])
+
+ def search(self, query: str, top_k: int = 5) -> list[dict]:
+ scores = self.bm25.get_scores(query.split())
+ return sorted(zip(self.chunks, scores), key=lambda x: -x[1])[:top_k]
+```
+
+### 变更文件
+- `src/smartinspector/commands/attribution.py` — 添加文件过滤和函数级分块
+- `src/smartinspector/agents/attributor.py` — 使用增强搜索替代现有grep
+- `requirements.txt` — 可选:添加 `pathspec`, `rank_bm25`
+
+### 不引入的
+- ❌ 向量数据库(Milvus/Zilliz)— 太重,CLI工具不应依赖外部服务
+- ❌ Embedding模型 — 增加延迟和成本,方法名匹配场景不需要语义搜索

+调用链的作用:
+1. **缩小搜索范围**:如果调用链包含具体的 Activity/Fragment 名称,

+2. **区分同名方法**:如果多个 Adapter 有同名方法(如 onBindViewHolder),

+3. **理解性能阶段**:调用链中的 [measure阶段]/[layout阶段]/[draw阶段]
