A required pull-request workflow has paths: ["src/**"]. A pull request changes only docs/readme.md, and the required check remains pending. What best explains this result?

1. GitHub automatically treats every skipped required workflow as a successful test run.
2. The documentation change has automatically changed the base branch to src.
3. The workflow needs packages: write to evaluate a path filter.
4. Path filtering skipped the required workflow before it reported success.
