Describe the bug

When generating SPDX output with west spdx, several files—especially from Zephyr or external modules—show NOASSERTION or empty fields, even though these files include valid license and copyright comments.

Regression

• This is a regression.

Steps to reproduce

1. Generate SPDX using west spdx
2. Inspect the SPDX output (e.g. modules-deps.spdx, zephyr.spdx)
3. Notice missing copyright/license data

Relevant log output

Impact

Annoyance – Minor irritation; no significant impact on usability or functionality.

Environment

• Zephyr
• west
