WHY IT NEEDS A POLICY

Why onpe_sv_refresh needs a policy

The tool performs an incremental UPSERT operation, which creates or modifies records in the local SQLite database. UPSERT (insert or update) is reversible in the sense that data can be overwritten again, placing this in the Write category. It does not delete data irreversibly, execute arbitrary code, or involve financial transactions.
