WHY IT NEEDS A POLICY

Why remnote_append_journal needs a policy

The 'append' operation creates or modifies data in a reversible manner (appending to a journal), making this a Write action rather than Read (which would only retrieve data) or Destructive (which would be irreversible deletion).

From the tool's definition Tool name is 'remnote_append_journal' and description states 'Append content to today', indicating it modifies an existing journal entry by adding content to it, which is a reversible write operation.
