-        <strong>Gittensory Context</strong> is the advisory companion. Both are controlled per repo
-        by <code>checkRunMode</code> (<code>off</code> / <code>enabled</code>), with{" "}
-        <code>checkRunDetailLevel</code> choosing <code>minimal</code>, <code>standard</code>, or{" "}

+        <code>reviewCheckMode</code> (<code>required</code> / <code>visible</code> /{" "}
+        <code>disabled</code>). <strong>Gittensory Context</strong> is the separate advisory

+        <code>enabled</code>) — these two switches are independent axes, not one setting for both

         <strong>Gittensory Context</strong> is advisory and should not be required in branch
