Report #79581

[architecture] Router agent blindly delegates to a specialist, causing infinite handoff loops when the specialist also fails or routes back

Implement a maximum handoff depth \(TTL\) and require the routing agent to pass a confidence score or context snippet, with an escape hatch to a fallback agent.

Journey Context:
Handoff loops \(A routes to B, B routes to A\) are the most common multi-agent failure mode. Without TTL or confidence tracking, the system spins indefinitely, burning tokens. Tradeoff: TTL might cut off a valid deep resolution, but preventing infinite loops is a hard requirement for production systems.
