The security file [GlobalStreamSettings] section with maxPriorityInherit=50 caps the priority that child job streams can inherit from parents, preventing unbounded escalation that leads to scheduling imbalances during peak loads. This global constraint applies uniformly to all job streams without modifying individual definitions, loading at engine initialization and persisting across plan productions. Unlike general security limits, this targeted setting balances workload fairness while allowing explicit priority overrides where business rules demand them, with validation occurring during job stream enqueueing.
