Never below 1, TNA's guideline.), TNA_DISCOVERY_DAILY_BUDGET (Requests a day (UTC) before tools refuse. At most 3000, TNA's guideline.), TNA_DISCOVERY_CONTACT (An email address or URL appended to the User-Agent, so The National Archives can reach whoever runs the server.), TNA_DISCOVERY_STATE_DIR (Directory for the day's call count, the one file the server writes (a date and a number).).
