codecov/patch stays pending on GitHub PR even though upload succeeds (status_code=200)

[AAdewunmi]

Describe the bug
codecov/patch remains in a pending state on GitHub PRs even though the Codecov upload step succeeds (Process Upload complete, HTTP 200) and coverage report is generated/uploaded.

Environment (please complete the following information):

• Browser: N/A (issue observed in GitHub Checks/Codecov status integration)
• System: GitHub Actions CI (ubuntu-latest), codecov/codecov-action@v5, Codecov CLI v11.2.6

To Reproduce

1. Open a PR in AAdewunmi/Claims-Fraud-Risk-Scoring-Project (example: PR Codecov uploader fails on Apple ARM64 hardware #141).
2. Run CI workflow with Codecov upload (codecov/codecov-action@v5).
3. Confirm upload logs show success:
   • coverage file found
   • upload request accepted
   • Process Upload complete with status_code=200
4. Wait for check processing and refresh PR checks.
5. Observe codecov/patch stays pending.

Expected behavior
After a successful upload, Codecov should post/update PR status checks (codecov/patch, project status) to completed pass/fail, not remain pending indefinitely.

Screenshots
Attached in issue context:

• Codecov action log showing successful upload (status_code=200, Process Upload complete)
• PR checks showing codecov/patch pending
