Cell F14 (ENG-2592). !#if directive gating (ENG-2578), third-party so the Standard gate cannot mask it. Ours after Networking #213 drops the env_safari block; a build before #213 applies it (red first). Brave's rows are source: its components strip the branch.
Rows, rules and Brave's verdicts are in pages/network-fixtures.json. The runner grades from CDP, never from this page.
