The only in-scope test file changed is x-pack/solutions/security/test/security_solution_cypress/cypress/screens/agent_builder.ts, which adds two new constant selector definitions (ENTITY_ATTACHMENT_CARD_ACTIONS, ENTITY_ATTACHMENT_OPEN_ENTITY_ANALYTICS_ACTION). This is a deterministic, mechanical addition of CSS selector constants — no new tests, no timing changes, no unskipped tests, no new async interactions. A single CI pass is sufficient to validate this change; no flaky test runner nudge is warranted.
