+
+## Summary
+
+Improve the torch proxy compatibility layer so enabling the proxy automatically exposes public `paddle.compat` overrides through the corresponding `torch` namespace, including overrides located in nested submodules.
+
+## Why This Is A Good SWE-Paddle Candidate
+
+- It comes from a merged Paddle compatibility PR and represents a refactoring-oriented task rather than a conventional bug fix.
+- The expected behavior is externally observable through the proxy namespace instead of implementation-specific source structure.
+- The task covers both automatic override registration and nested module proxying while preserving existing fallback behavior.
+- The production change is Python-only and can be verified deterministically on CPU without building Paddle native extensions.
+
+## Files
+
+- `proposal.md`: candidate proposal for maintainer triage.
+- `instruction.md`: self-contained task statement.
+- `solution/code.patch`: production-only Gold patch.
+- `tests/test.patch`: independent regression tests.
+- `tests/test.sh`: minimal target test command.
+- `environment/README.md`: reproduction environment notes.
+- `README.md`: task overview and verification entrypoint.
+
+## Verification
+
+```bash
+bash tests/test.sh
+```
+
+Expected behavior: with only `tests/test.patch` applied to the Base commit, the existing proxy fallback test passes while the new compatibility-override tests fail. After applying `solution/code.patch`, all target tests pass.

+# Environment Notes
+
+This candidate is part of the SWE-Paddle community task set.
+
+## Expected Environment
+
+- Repository: `PaddlePaddle/Paddle`
+- Base commit: `b5efb98a163a2be2505e72266841e64b88254a8a`
+- Resource: CPU
+- GPU required: no
+- Build path: Paddle source checkout at the base commit. This Python-only task executes the checkout proxy module with controlled Python modules; a Paddle native source build is not required.
+
+## Run Order
+
+1. Check out `PaddlePaddle/Paddle` at the base commit.
+2. Apply `tests/test.patch`.
+3. Run `bash tests/test.sh`; the target compatibility behavior should fail before the change.
+4. Apply `solution/code.patch`.
+5. Run `bash tests/test.sh` again; all target tests should pass.
+
+## Minimal Test Command
+
+```bash
+bash tests/test.sh
+```
+
+The verifier is responsible for deriving stable F2P and P2P node IDs from repeated runs.

+# 完善 Torch Proxy 对兼容接口的覆盖行为
+
+## 详细描述
+
+启用 Paddle 的 Torch Proxy 后，`paddle.compat` 中公开提供的兼容接口应能够通过对应的 `torch` 命名空间直接访问，无需调用方逐一配置。
+
+当前代理对这类兼容接口的处理不完整。特别是当接口位于嵌套模块中时，通过父级模块访问或使用 import 语句导入，可能无法得到预期的兼容实现。
+
+请完善 Torch Proxy 的接口覆盖行为，确保公开的兼容接口在对应命名空间中正确生效，同时保持现有的接口覆盖和默认代理行为不变。
+
+## 验收说明
+
+* 启用 Torch Proxy 后，`paddle.compat` 各子模块公开提供的接口应能够通过对应的 `torch` 命名空间访问
+* 未公开的兼容接口不应被暴露到 `torch` 命名空间
+* 嵌套模块中的兼容接口通过属性访问时，应返回对应的兼容实现
+* 嵌套模块中的兼容接口通过 import 语句导入时，应返回对应的兼容实现
+* 已有的接口覆盖行为不得发生变化
+* 对于没有兼容实现或已有覆盖的属性，现有的默认代理行为不得发生变化
+
+## 技术要求
+
+* 熟悉 Python import system、模块代理和动态属性访问机制
+* 理解 Paddle Torch compatibility layer 的模块映射方式
+* 了解嵌套模块的加载、导入和属性解析过程
+* 测试应验证运行时可观察行为，不依赖源码文本、局部变量名或特定的内部数据结构

+# Task Proposal: PaddlePaddle__Paddle-76522
+
+## 1. 来源信息
+
+- Instance ID：`PaddlePaddle__Paddle-76522`
+- PR 链接：https://github.com/PaddlePaddle/Paddle/pull/76522
+- PR 标题：`[Compat] Auto register compat module overrides when enable torch proxy`
+- `base_commit`：`b5efb98a163a2be2505e72266841e64b88254a8a`
+- Gold commit：`20d9626540daf86096cc5bd11c9b84b398ce7138`
+- merged 时间：`2025-11-24`
+- 你的身份：熟悉该模块的 contributor
+- 后续联系人：TBD
+
+## 2. 问题一句话
+
+完善 Torch Proxy 的兼容接口覆盖机制，使其在启用时自动注册 `paddle.compat` 中公开提供的接口，并确保嵌套模块中的兼容实现能够通过对应的 `torch` 命名空间正确访问。
+
+## 3. 为什么适合作为 SWE-Paddle 样本
+
+- **真实性**：任务来自已合入的 Paddle PR #76522，不是人工构造的需求。
+- **类型多样性**：该任务属于 compatibility layer 的功能完善，可补充 SWE-Paddle 中以常规 bug fix 为主的任务分布。
+- **可观察性**：兼容接口是否被自动注册、嵌套模块是否返回预期实现，以及未覆盖属性是否保持原有代理行为，都可以通过运行时对象身份稳定验证。
+- **边界清楚**：production change 集中在 `python/paddle/compat/proxy.py`，原 PR 中的测试改动可以与 Gold production patch 清晰分离。
+- **环境友好性**：核心逻辑涉及 Python 模块导入、属性访问和代理行为，可以在 CPU 环境中直接运行 checkout 源码，无需 GPU 或 Paddle native source build。
+
+## 4. 任务类型和标签
+
+- 任务类型：`feature_enhancement`
+- 执行后端：`cpu`
+- 设备范围：`cpu_only`
+- 模块标签：`[compat, torch_proxy, import_system, module_proxy, api_compatibility]`
+
+## 5. 验证思路
+
+- 目标测试命令：`bash tests/test.sh`
+- 目标测试文件：`test/swe_paddle/test_pr76522_torch_proxy_compat_overrides.py`
+- 修复前预期：没有兼容接口覆盖的属性应继续按原有逻辑返回 Paddle 模块中的对应对象；自动注册 `paddle.compat` 公开接口以及嵌套模块覆盖相关测试应失败。
+- 修复后预期：应用 production Gold patch 后，P2P 与全部 F2P 均应 pass；公开兼容接口能够通过属性访问和 import 语句从对应的 `torch` 命名空间获得。
+- P2P 候选：没有兼容实现的属性继续返回原始 Paddle 对象；已有的 Torch Proxy override 行为保持不变。
+- F2P 候选：启用 proxy 时自动注册 `paddle.compat` 中公开导出的接口；嵌套模块中的兼容接口能够通过父模块属性访问和直接 import 正确生效；未公开接口不会被注册。
+
+## 6. 环境与资源
+
+- 资源需求：CPU
+- Paddle 来源：`PaddlePaddle/Paddle` source checkout at `base_commit`
+- 是否能提供 Docker：暂无
+- patch 类型：Python-only
+- 最小测试命令：`bash tests/test.sh`
+- 是否有 oracle 日志：由 SWE-Paddle verifier 结果另行维护
+
+## 7. 风险自查
+
+- 泄露风险：`instruction.md` 只描述兼容接口自动生效、嵌套模块访问和默认代理行为等运行时结果，不透露 Gold patch 中的类设计、注册过程或内部数据结构。
+- 环境风险：测试不依赖真实 PyTorch 安装，也不要求历史 Paddle wheel 与 source checkout 完全匹配。
+- flaky 风险：测试使用受控的 Python 模块和确定性的对象身份断言，不依赖网络、GPU、多进程或随机行为。
+- 拆分风险：兼容接口自动注册和嵌套模块覆盖共同构成 Torch Proxy 兼容行为的完整改进，且集中在同一 production 文件中，适合作为单个任务。
