Case contract

Bounded offline decision model: websocket upgrade requires both upgrade and connection tokens. Inputs are already validated protocol fields; the explicit fixtures define the supported policy, not a complete protocol implementation.

Why this case matters

This deterministic websocket and browser transport policies model isolates the websocket-upgrade-requires-both-upgrade-and-connection-tokens policy at a network component boundary.

One recorded failure

Sample boundary fixture
