Routing signals

• Data sensitivity: public, internal, personal, or secret.
• Expected difficulty: simple, medium, strong reasoning, or multimodal.
• Latency tolerance: interactive, batch, or overnight review.
• Need for citations, traceability, or human review.

Start with few rules. A router with ten clear policies usually works better than one with a hundred exceptions nobody understands.
