Report #31322

[architecture] Specialized agents failing silently on out-of-domain queries due to blind keyword routing

Require the router agent to output a confidence score; route low-confidence or ambiguous tasks to a generalist fallback agent rather than forcing a specialized agent to handle them.

Journey Context:
Keyword-based routing is brittle. Specialized agents will attempt to answer questions outside their expertise due to sycophancy, producing garbage. A generalist fallback prevents catastrophic failures from over-specialization and handles edge cases gracefully.
