[synthesis] Recursive delegation depth overflow in hierarchical agents

Enforce max delegation depth \(2 levels\); require sub-agents return structured output, never spawn new agents

Journey Context:
Hierarchical patterns \(AutoGen, CrewAI\) allow agents to delegate indefinitely. Without depth tracking, context windows explode and stack traces become unreadable. Hard depth limits force flat architectures or explicit workflow graphs rather than emergent recursion. The failure mode is 'agent A delegates to B which delegates to C...' until context limit hit with no actual work done.
