+### 3.3 四阶段工作法（强制，不可跳过任何阶段）
 
-每次改动**必须**按顺序完成以下步骤，不允许跳过：
+任何操作 — 无论是修 bug、加功能、重构、还是回答技术问题 — 都必须按以下 4 个阶段执行。不允许跳过、不允许合并阶段。
 
-1. **定位问题** — 理解根因，不盲目堆补丁
-2. **最小修复** — 只改必要的代码
-3. **自动验证** — `tsc --noEmit` / `cargo check` / `vitest run` 必须通过
-4. **提交推送** — 按 §11 规范提交，**立即 `git push`**，不积压
-5. **文档同步** — 按 §8.3 检查并更新相关文档，提交并推送
+#### 阶段 1: 理解背景（先读 wiki）
 
-**铁律：步骤 4 和 5 是任务完成的硬性条件。不允许"等一下再提交"或"最后一起推送"。**
+**接到任务后，第一件事是阅读 wiki 获取上下文，而不是直接动手。**
+
+1. 读取 `wiki/index.md` — 理解全局架构，利用**症状导航表**快速定位相关模块
+2. 读取对应模块页 — 每个模块页统一 5 节结构：设计决策 → 关键文件+集成契约 → 代码逻辑(不变量) → 活跃问题+陷阱 → 变更记录
+3. 如涉及已知问题，检查模块页的"活跃问题"节（全局索引见 `wiki/known-issues.md`）
+
+**判断标准**: 你能用一句话说清楚"这个改动涉及哪个模块、走哪条数据链路、影响哪些组件"吗？如果不能，你还没读完。
+
+#### 阶段 2: 制定方案（先想清楚再动手）
+
+基于阶段 1 的理解，制定执行方案：
+
+1. **定位根因** — 确认属于哪一类问题（协议/状态/UI/配置/运行时），不盲目堆补丁
+2. **确定影响范围** — 哪些文件需要改？哪些 crate 受影响？有没有上下游依赖？
+3. **列出执行步骤** — 按顺序列出要改的文件和验证点
+4. **预判风险** — 这个改动可能破坏什么？需要跑哪些测试？
+
+**判断标准**: 你能用 3 句话说清楚"改什么、为什么改、改完怎么验证"吗？如果不能，方案还不成熟。
+
+#### 阶段 3: 执行 + 验证
+
+1. **最小修复** — 只改必要的代码
+2. **自动验证** — `cargo check` / `cargo test` / `tsc --noEmit` / `vitest run` 必须通过
+3. **回归测试** — 跑受影响 crate 的全量测试，确认无回归
+
+#### 阶段 4: Wiki 同步 + 提交（立即，不积压）
+
+**Wiki 同步评估（硬门槛，不可跳过）**
+
+代码改完后、提交前，逐条回答以下问题。任何一条为"是"→ 必须更新对应 wiki 页面：
+
+| 评估问题 | 为"是"时更新 |
+|----------|-------------|
+| 这个改动修复或引入了 bug？ | 对应模块页"活跃问题+陷阱"节 + `wiki/known-issues.md` |
+| 这个改动改变了某个模块的行为或设计理由？ | 对应模块页"设计决策"节 |
+| 这个改动增删了文件或改变了目录结构？ | 对应模块页"关键文件"表 |
+| 这个改动影响了跨模块接口（谁调谁、参数形状、触发时机）？ | 涉及双方的"集成契约"表 |
+| 这个改动涉及一个必须始终成立的约束？ | 对应模块页"代码逻辑"节的 ⚡ 不变量 |
+| 这个改动改变了功能链路（前端→后端的完整路径）？ | `wiki/feature-map.md` 索引表 |
+| 这个改动改变了关键数字（命令数/Store数/测试数等）？ | `wiki/index.md` 关键数字表 + `docs/TRUTH.md` |
+
+全部回答完后，无论是否有更新，都追加一条到 `wiki/log.md` + 更新模块页"变更记录"节（保持 5 条）。

+## 15. Karpathy 编码原则
+
+> 源自 Andrej Karpathy 对 LLM 编码问题的观察。偏向谨慎而非速度，简单任务可灵活判断。
+
+### 15.1 Think Before Coding
+
+**Don't assume. Don't hide confusion. Surface tradeoffs.**
+
+- State assumptions explicitly. If uncertain, ask.
+- If multiple interpretations exist, present them — don't pick silently.
+- If a simpler approach exists, say so. Push back when warranted.
+- If something is unclear, stop. Name what's confusing. Ask.
+
+### 15.2 Simplicity First
+
+**Minimum code that solves the problem. Nothing speculative.**
+
+- No features beyond what was asked.
+- No abstractions for single-use code.
+- No "flexibility" or "configurability" that wasn't requested.
+- No error handling for impossible scenarios.
+- If you write 200 lines and it could be 50, rewrite it.
+
+Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify.
+
+### 15.3 Surgical Changes
+
+**Touch only what you must. Clean up only your own mess.**
+
+When editing existing code:
+
+- Don't "improve" adjacent code, comments, or formatting.
+- Don't refactor things that aren't broken.
+- Match existing style, even if you'd do it differently.
+- If you notice unrelated dead code, mention it — don't delete it.
+
+When your changes create orphans:
+
+- Remove imports/variables/functions that YOUR changes made unused.
+- Don't remove pre-existing dead code unless asked.
+
+The test: Every changed line should trace directly to the user's request.
+
+### 15.4 Goal-Driven Execution
+
+**Define success criteria. Loop until verified.**
+
+Transform tasks into verifiable goals:
+
+- "Add validation" → "Write tests for invalid inputs, then make them pass"
+- "Fix the bug" → "Write a test that reproduces it, then make it pass"
+- "Refactor X" → "Ensure tests pass before and after"
+
+For multi-step tasks, state a brief plan:
+
+```
+1. [Step] → verify: [check]
+2. [Step] → verify: [check]
+3. [Step] → verify: [check]
+```
+
+Strong success criteria let you loop independently. Weak criteria ("make it work") require constant clarification.
+
+---
+
+**These guidelines are working if:** fewer unnecessary changes in diffs, fewer rewrites due to overcomplication, and clarifying questions come before implementation rather than after mistakes.
