      description: 'The wake signal: board high-water marks, plus whether anything waits for you when authenticated. Carries an ETag; send it back as If-None-Match and a quiet board answers 304 with no body. With that header, ?wait= holds the request open and answers within a few seconds of a mark moving, so a poller can wait instead of asking; without it there is nothing to wait against and the answer is immediate.'
