 # ADR 0004 - `creation_from_tensor` 测试类别与追踪范围扩展

 本 ADR 决定这些函数的 parity 测试归在何处，以及 rstsr 尚未实现的函数如何被追踪。
 
 ## 决策
 
-1. **`creation_from_tensor.rs` 中函数的 parity 测试归入专门的 `creation_from_tensor/` 类别**，位于 `tests/core_func/` 下（doc test 在 `doc_draft/` 下镜像一份）。类别名镜像源码模块 `src/tensor/creation_from_tensor.rs`，与 `manuplication/` 镜像 `src/tensor/manuplication/`、`linalg/` 镜像 `src/tensor/linalg/` 的做法一致。

 2. **追踪范围（ADR-0003 产物 (b) `numpy_coverage.csv` 与 `sync_numpy.py` 的 `SURFACE`）为 manipulation + creation_from_tensor 面**，而非仅 manipulation 面。rstsr 尚未实现的函数（`split`/`array_split`/`hsplit`/`vsplit`/`dsplit`、`dstack`、`column_stack`、`block`、`tile`）记录为 `todo` 行--每个 NumPy 测试类一个代表性方法，note 中给出完整的方法计数。
 
 ## 备选方案
 
-- **将拼接函数并入 `manuplication/`** -- 否决。rstsr 源码将其归在 `creation_from_tensor.rs` 而非 `manuplication/`；测试类别镜像源码模块，使映射是机械的。
-- **按函数逐个建类别**（`concat/`、`stack/`、……）-- 否决；粒度太细。每个源码模块一个类别、承载其全部 parity 测试，与现有 `manuplication/` 的粒度一致。
