Solutions

1. Use one of gstz (公示通知), xswh (学术文化), jyzd (就业指导).
2. Cross-check against the route description table.
3. Treat each njust/* route as having an independent code set.

Example fix

// before
const info = map.get(type);
if (!info) {
    throw new InvalidParameterError('invalid type');
}

// after — caller: GET /njust/dgxg/gstz | xswh | jyzd

const VALID = new Set(['gstz','xswh','jyzd']);
function buildNjustDgxgUrl(type) {
  if (!VALID.has(type)) throw new Error(`invalid type '${type}'. Valid: ${[...VALID].join(', ')}`);
  return host + MAP[type] + '/list.htm';
}

const isDgxgType = (t: string): t is 'gstz'|'xswh'|'jyzd' => VALID.has(t);

When it happens

Trigger: Calling /njust/dgxg/:type with a value outside the route's map — typo or a code from a sibling route.

Common situations: User copies a code from njust/eoe or njust/cs that is not valid here; typo; docs drift.
