Function scan_unscanned_references 

pub async fn scan_unscanned_references(
    pool: &PgPool,
    vault: &Vault,
) -> AppResult<u64>

Scans the current versions that were stored before reference tracking existed (or before their format was known) for referenced CAD files. Returns how many versions were scanned.

Invariants

• Permission: none (maintenance task of the server, no actor).
• Locks: none.
• Audit / notifications / webhooks: none.
• Atomic: one transaction per version (references::store_file_references stores the names and sets references_scanned), so an interrupted run can be repeated.
