Static

Overview

static is the simplest selection algorithm: the route keeps its candidate list, and the selection policy stays fixed.

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

Key Advantages

• Deterministic and easy to reason about.
• No learned selector state or runtime tuning.
• Good default when the candidate order is already intentional.

What Problem Does It Solve?

Sometimes the route just needs a stable winner policy without extra scoring logic. static makes that explicit instead of leaving selection behavior implicit.

When to Use

• one candidate should always win after the route matches
• model ordering is already curated outside the algorithm layer
• you want the simplest possible route-local selection policy
