+
+## Summary
+
+Add `sparse.mask_as` API for Paddle, which extracts values from a dense tensor at positions indicated by a sparse mask and outputs a sparse tensor.
+
+## Files
+
+- `proposal.md`: candidate proposal for maintainer triage.
+- `instruction.md`: self-contained problem statement for the coding agent.
+- `solution/code.patch`: gold patch from the merged PR.
+- `tests/test.patch`: test patch exposing the target behavior.
+- `tests/test.sh`: minimal target test command.
+- `environment/README.md`: environment notes for reproduction.
+
+## Verification
+
+```bash
+bash tests/test.sh
+```
+
+Expected behavior: applying `tests/test.patch` to `base_commit` should fail on the target behavior; applying both `tests/test.patch` and `solution/code.patch` should pass the target tests.

+# Environment Notes
+
+This candidate is part of the SWE-Paddle task set.
+
+## Expected Environment
+
+- Repository: `PaddlePaddle/Paddle`
+- Base commit: `605f5e20305db0e4932a20d3e0e6cf7d7d9631d8`
+- Resource: CPU + GPU
+- GPU required: yes (CUDA kernels are included)
+- Build path: Paddle source checkout at the base commit. This task involves C++ CPU kernels, CUDA GPU kernels, Python API, and YAML op definitions, so source build is 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 behavior should fail before the fix.
+4. Apply `solution/code.patch`.
+5. Run `bash tests/test.sh` again; the target behavior should pass after the gold patch.
+
+## Minimal Test Command
+
+```bash
+bash tests/test.sh
+```
+
+The verifier is responsible for deriving stable F2P and P2P node IDs from repeated runs.

+# 新增 sparse.mask_as API
+
+## 详细描述
+
+为 Paddle 稀疏计算新增 `sparse.mask_as` API。该 API 根据给定的稀疏 mask（SparseCooTensor 或 SparseCsrTensor），从稠密 Tensor 中提取对应非零位置的值，输出一个与 mask 具有相同 indices 的稀疏 Tensor。
+
+要求支持：
+- COO 格式：支持 1-D ~ 4-D 输入
+- CSR 格式：支持 2-D 和 3-D 输入（其他维度应报错）
+- 数据类型：float32, float64, int32, int64, complex64, complex128, int8, int16, float16
+- 前向计算 + 反向梯度
+
+## 验收说明
+
+- `paddle.sparse.mask_as(x, mask)` 应能正确根据 mask 的 indices 从稠密 Tensor x 中提取值
+- 支持 COO 和 CSR 两种稀疏格式
+- CSR 格式仅支持 2-D 和 3-D，其他维度应报错
+- 反向梯度应正确传播
+
+## Acceptance Criteria
+
+- The behavior described above should be fixed.
+- Existing valid behavior should remain unchanged.
+- Do not satisfy the task by deleting tests, weakening assertions, or bypassing validation broadly.
