Root cause: transient setup-phase failures (slow Kibana response, container killed by CI). These are environment issues, not package problems.

Fix: elastic/elastic-package#3888 (PR elastic/elastic-package#3919) implements setup-phase re-attempt — when a test fails during policy creation, agent enrollment, or service startup, it is re-attempted from scratch. Data-validation failures (real signal) are never re-attempted.

Closing as we have public issue for tracking.
