WHY IT NEEDS A POLICY

Why create-ledger needs a policy

Creating a ledger master is a reversible write operation that modifies core financial configuration. It is not destructive (the ledger can be deleted or marked inactive), not financial (it doesn't move money, only creates an accounting container), and not execute (it doesn't run arbitrary code).

From the tool's definition Tool description states it 'creates a new GL ledger master in Tally Prime' — a permanent addition to the chart of accounts that modifies the financial master data structure.
