Doug Lovett Note 2026-05-21:
The business api now gets all filing ledger client documents from the DRS. Outstanding is the work to add these documents to the ledger, possibly conditional on user access role (staff only) and DRS document type/filing type. A DRS document may not be associated with a filing. In colin I believe these client documents show up in the ledger history as "document image" links if they are scanned.

BA work may be needed to determine by filing type/document type which documents show up in the ledger for clients/staff.
