The answer is NO, they cannot be deleted without a trace. Key Points: 1. Transaction logs capture activity All user actions (including table access via URI) are recorded in transaction logs and can be searched. 2. No log entries = no observed access If specific tables (e.g., flows, integrations) are not seen in logs, there is no evidence they were accessed via standard transactions. 3. Deletions are typically tracked: When auditing is enabled: Deleting a record creates entries in audit tables (e.g., sys_audit_delete).Audit systems retain metadata like who deleted the record and when. 4. Deleting logs is non-trivial Requires knowledge of the record (Sys ID) and elevated (admin) accessDeletion actions themselves can be logged and traced (if auditing is enabled) Summary: If a record is deleted from the transactional logs, the action must first be performed by users with high-privileged roles such as security_admin or admin. Additionally, when transactional log records are deleted, those entries are retained in the Deleted Records table. If a user then deletes the records from the Deleted Records table as well, that action is again captured by the transactional logs, resulting in a continuous, non-erasable audit trail. Logs provide reliable visibility into activity.Lack of entries suggests no observed access.Deletions generally leave audit traces.Completely removing all traces is difficult and requires high privilege and multiple steps.
