Skill: Resource Bounds / DoS Resistance (CWE-400, CWE-770)

• Loops over user-supplied slices (PodSets, ResourceGroups, Flavors, cohort children, admission checks) without a documented webhook-enforced cap or explicit length check.
• make([]T, n) / make(map[K]V, n) where n comes from user data without a sanity cap.
• Outbound API or HTTP calls without context.WithTimeout (or a bounded inherited reconcile context).
• Invalid .spec.interval-style fields that could wedge the reconciler for the entire kind (CVE-2022-39272 pattern). Failures from invalid CR content must surface to status, not crash-loop.
• New metrics with unbounded label cardinality — workload_name, pod_name, namespace+name composites, annotation values as labels.
