Hybrid

Overview

hybrid is a selection algorithm that combines several ranking signals into one weighted score.

It aligns to config/algorithm/selection/hybrid.yaml.

Key Advantages

• Blends multiple selectors instead of committing to only one.
• Makes weighting explicit and easy to audit.
• Supports gradual migration between ranking policies.

What Problem Does It Solve?

No single selector is always enough. hybrid lets one route combine feedback, semantic matching, and cost-aware routing without duplicating combination logic elsewhere.

When to Use

• one route should combine several ranking signals
• you want a weighted transition between older and newer selectors
• the final choice should reflect both quality and operational cost

Configuration
