The PR introduces the new teardown modes, but the run-selection guard is wired to the wrong payload shape, so teardown is likely skipped whenever deploy_test_cases is populated.

→ Security Review

Status: ✅ Completed
Suggestions: 0 suggestions

No security-relevant findings in this PR diff. The change only adjusts auto-teardown behavior and adds run-payload metadata without introducing an obvious injection, authz, secret, or exposure issue.

→ Performance Review

Status: ✅ Completed
Suggestions: 0 suggestions

No performance regressions or scalability issues stood out in this diff; the new teardown-mode checks are lightweight and bounded.

Status: ✅ Completed
Suggestions: 1 suggestion

The PR adds new auto-teardown modes and selection gating, but there is no regression coverage for the new branches or the deploy payload field they depend on.
