Equal quality retains server preference order.

Case contract

Bounded offline decision model: equal quality retains server preference order. Inputs are already validated protocol fields; the explicit fixtures define the supported policy, not a complete protocol implementation.

Why this case matters

This deterministic content negotiation model isolates the equal-quality-retains-server-preference-order policy at a network component boundary.

One recorded failure
