Why flagged
The record's entry timestamp precedes the instrument acquisition time, indicating data was entered out of sequence. Contemporaneous capture requires recording at the time work is performed.
Source evidence
entry_timestamp 09:02 < acquisition_time 11:47 on the same worksheet.
Suggested remediation
Confirm the true acquisition time from raw instrument metadata and correct the entry timestamp with a documented justification.
