[no-ci] cuda_core: fix SPDX identifiers and enforce Apache-2.0 headers (#1897)

rwgk · web-flow · commit 23ab9a056340 · 2026-04-14T12:50:13.000-07:00
* Systematically correct SPDX-License-Identifier: Apache-2.0

* toolshed: enforce cuda_core SPDX license policy

Refactor the SPDX checker so package-specific license rules can be enforced cleanly while preserving the existing autofix flow. Keep focused regression coverage alongside the toolshed script instead of in routine package test collection.

Made-with: Cursor

* Remove toolshed/test_check_spdx.py (too much trouble adding it to the CI, but it will bit-rot if untested).

* toolshed: normalize SPDX paths with PureWindowsPath

Use a standard-library path normalizer so repo-prefix checks treat Windows-style paths consistently on any host. Document why os.path.normpath is not suitable for this forward-slash prefix comparison.

Made-with: Cursor
