+    // that aren't columns (e.g. the risk register's project/discipline/
+    // sequence tracking-number components, composed server-side or set via the
+    // add-row form) are NOT inline-fillable, so the client must not block on
+    // them — the server validates those (and composes them) authoritatively.
