Charset default is not inferred from an unrelated media type · case 04

Charset default is not inferred from an unrelated media type.

Case contract

Bounded offline decision model: charset default is not inferred from an unrelated media type. 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 charset-default-is-not-inferred-from-an-unrelated-media-type policy at a network component boundary.
