The failing GitHub Actions run was caused by stale test assumptions rather than a CLI regression. The install suite now seeds repo-local git identity before helper commits, the codex-agent no-merge assertion no longer hardcodes the role segment, and the metadata suite accepts the current doctor dry-run variable name.

Constraint: CI runners do not provide global git author identity for nested test repos

Rejected: Change runtime branch naming or doctor output to satisfy stale tests | behavior already matches the intended contract

Confidence: high

Scope-risk: narrow

Directive: Keep tests focused on user-visible behavior instead of local variable names or fixed role prefixes

Tested: npm test

Not-tested: live GitHub Actions rerun after merge
