Which Maratha official was in charge of royal correspondence, responsible for managing the Royal Household and maintaining the daily court diary?

कौन सा मराठा अधिकारी शाही पत्राचार का प्रभारी था, जो राजघराने के प्रबंधन और दैनिक अदालती डायरी (दरबारी दैनिकी) बनाए रखने के लिए जिम्मेदार था?

In Shivaji's Ashtapradhan council, the Sachiv (also called Surnis or Chitnis) was responsible for royal correspondence, checking official letters and looking after the accounts of the royal household and court records. Of the options, the Amatya looked after revenue and accounts, the Sumant (Dabir) after foreign affairs, and the Danadhyaksha (Pandit Rao) after religious matters and charity, so only the Sachiv fits the description.
