Why flagged
A reported value was edited after it had moved to an approved state, and no change reason was captured. Silent edits to original data break the chain of custody.
Source evidence
Value changed 18.4 → 12.1 µg/L; no entry in change_reason; edit timestamp post-dates approval.
Suggested remediation
Revert to the original instrument value or attach a signed change-control note documenting the reason, prior value, and authorizing reviewer.
Reviewer decision
Awaiting a reviewer. No decision recorded yet.
