Why flagged

The result was recorded without a verified analyst identity. Records that cannot be traced to a specific, authenticated user fail the Attributable principle and are not defensible during inspection.

Source evidence

Instrument session 7900-S4421 has no logged operator for this acquisition.

Suggested remediation

Re-associate the entry with the authenticated analyst from the instrument session log, or obtain a documented attribution statement countersigned by the QA Manager.
