Pull request overview
This PR updates the main CI workflow to avoid workflow-level paths-ignore (which can prevent required checks from registering), and instead introduces a “changes” pre-job that decides whether to run heavy CI based on whether any non-documentation files changed.
Changes:
- Remove workflow-level
paths-ignorefrom.github/workflows/cicd_tests.ymlso checks always register on PRs. - Add a
changesjob that computes arun_testsoutput by diffing changed files and treatingdocs/**,*.md, and*.rstas docs-only. - Gate heavy jobs (
static-checks,min-dep,full-dep,packaging) onneeds.changes.outputs.run_tests.

Inline comments:
In @.github/workflows/cicd_tests.yml:
- Around line 52-54: The read-only checkout in the workflow still persists Git
credentials, which is unnecessary for this job. Update the actions/checkout step
in the CI workflow to explicitly disable credential persistence by setting
persist-credentials to false alongside fetch-depth, so the checkout does not
store the token in git config.
- Around line 47-51: The changes job in the workflow is missing an explicit
permissions block, so it inherits broader default GITHUB_TOKEN access than
needed. Add a least-privilege permissions setting to the changes job itself,
keeping only the read access required for diffing repository files. Update the
job definition near the changes and steps keys so the permissions are scoped
directly to that job.
- Around line 61-72: The PR diff in the workflow step is interpolating
github.base_ref directly into the shell script, which triggers
template-injection concerns. Update the changed-files logic to pass
github.base_ref into the step via env and read it as a shell variable inside the
script instead of embedding it in base_ref assignment and git fetch. Keep the
existing behavior in the pull_request branch, but ensure both the base_ref
calculation and fetch call use the env-backed variable rather than a GitHub
expression.
- Around line 58-84: The changes-detection step in cicd_tests.yml can fail
closed under set -euo pipefail when git fetch or git diff errors, which prevents
the changes job from setting a safe default. Update the shell logic around the
changed_files computation so any diff-detection failure in the current changes
job path falls back to run_tests=true instead of exiting, and add a timeout to
the fetch/diff operation; keep the fix localized to the workflow step that uses
github.event_name, git fetch, git diff, and the run_tests output.

🌐 Web query:
GitHub Actions skipped job required status check branch protection treated as success or failure
💡 Result:
GitHub treats a skipped job as a successful status for the purposes of branch protection [1][2][3]. When a job is skipped—for example, due to a conditional if expression—it reports its status as "Success," meaning it will not block a pull request from merging even if that job is configured as a required status check [1][2][4]. However, the behavior differs depending on why the job was skipped: 1. Job-level conditionals: If a job within a workflow is skipped because its if condition evaluated to false, it is treated as a success [5][2]. This can lead to unintended results if you rely on that job to validate your code [6]. 2. Workflow-level filtering: If an entire workflow is skipped due to path filtering, branch filtering, or a commit message, the associated checks will remain in a "Pending" state [7][2][8]. Because they never report a status, they will block the pull request from merging if they are configured as required [7][2][8]. 3. Dependency chains: If a job is skipped because a prerequisite job failed, it is also treated as a success [6][2]. To prevent this, you can use the always() conditional expression in your job's if field to ensure the job runs (and reports a failure) even if its dependencies failed [6][2][8]. For required checks that depend on conditions, it is generally recommended to avoid using path or branch filtering if the workflow is required for merging [8]. Instead, consider using the always() function to ensure that downstream jobs explicitly report a failure status if required upstream tasks do not succeed [6][2].

Fail open when diff detection breaks .github/workflows/cicd_tests.yml:58-84
git fetch/git diff under set -euo pipefail can fail the changes job, which skips every needs: changes test job. Skipped required checks pass, so a transient diff error can let untested changes merge. Default run_tests=true on diff failures and add a timeout.

Hi @SID-6921 thanks for this contribution but I don't see this helping enough for what I had wanted in the issue. From the script it looks like this will only detect when appropriate files are changed, what I had experimented with here was checking that Python files have actual code changes, such that docstring or comment changes don't trigger testing. I think that's important, and the issues from Copilot and Coderabbit are relevant to look at also. I think my implementation could use work to prevent failure allowing tests to be skipped as well, but skipping tests for docstring changes is also desired. If you wanted to update from these comments I can re-review, otherwise I'd prefer to close this PR.

Why
Workflow-level paths-ignore can prevent required checks from appearing at all for doc-only PRs, which blocks mergeability. With this change, checks are always created, and heavy jobs are skipped only when changes are docs-only.
