Systemic CI failure: PHP 8.2 (2 events)

Summary

Brief recovery attempted after the original alert combined unrelated failures.

Worker Guidance

Goal

Classify the reported PHP 8.2 failures accurately and avoid an unsupported shared-workflow change. The historical SSO assertions are already resolved on main by commit f4e9ab38 (fix: align SSO test defaults (#1749)). The remaining PHP 8.2 failure on PR #1745 is an exit-137 termination that also affects PHP 8.4 and 8.5 on that PR; it is not evidence of the original cross-PR systemic condition.

Files Scope

No repository files are authorized for this issue. This recovery confirms that the original signal does not identify a shared implementation change.

Files to Inspect First

1. .github/workflows/tests.yml — PHP matrix and PHPUnit invocation.
2. tests/WP_Ultimo/SSO/SSO_Coverage_Test.php — historical assertion fixed by #1749.
3. tests/WP_Ultimo/SSO/SSO_Extended_Test.php — historical assertion fixed by #1749.

Implementation Steps

1. Verify f4e9ab38 is reachable from origin/main; do not duplicate the SSO test fix.
2. Verify PR #1745's latest PHP matrix still reports exit 137 for PHP 8.2, 8.4, and 8.5 while PHP 8.3 succeeds.
3. Record this issue as a non-actionable false systemic grouping. Do not change .github/workflows/tests.yml; diagnose the remaining PR-specific failure on its source PR.

Verification

git merge-base --is-ancestor f4e9ab38 origin/main
gh pr view 1745 --repo Ultimate-Multisite/ultimate-multisite --json headRefName,headRefOid,statusCheckRollup
gh run view 33536861986 --repo Ultimate-Multisite/ultimate-multisite --job 99953421296 --log-failed

Runtime Testing

Risk: low (issue triage only). Runtime execution is not required because this issue authorizes no source or workflow modification. Existing reproduction context is the PHP 8.2 exit-137 log and the superseded SSO assertions above.

aidevops.sh v3.32.296 automated scan.

Start with .github/workflows/tests.yml and the two SSO test files, then verify commit f4e9ab38 on origin/main. Inspect PR #1745 and the referenced failed job to confirm the exit-137 matrix results. Done means documenting this as a non-actionable grouping without changing the workflow; any remaining failure belongs to PR #1745.
