Если выше показаны заголовки ответа бэкенда, то я в первую очередь
не вижу, почему бы этому файлу кэшироваться. То есть - каковы
причины для возникновения HIT?

В отсутствии явно заданных заголовков Cache-Control / Expire /
X-Accel-Expire - единственная возможная причина кэширования это
директива proxy_cache_valid, если она в конфиге есть - то
вероятнее всего отвечает на оба вопроса.
