+
+## FRE-4794: Review silent active run for Code Reviewer
+
+**Assessment: False Positive.** Run `77d215d0` was an orphaned child-process retry on FRE-4638.
+
+- Original process died, Paperclip queued a retry, retry adapter invocation produced zero output
+- Process pid `2139532` confirmed dead since May 4
+- Real review work was completed in prior run `efb2d246` — Code Reviewer reviewed 3 loan sheets, added missing `fetchActiveLoans()`, committed `bba6b29`, declared "Ready for Security Review"
+- No artifacts lost; dead retry that never initialized
+
+**Action:** Closed done as false positive.
+
+## FRE-4793: Review productivity for FRE-4638
+
+**Assessment: False Alarm.** The `long_active_duration` (6h) was driven by the orphaned retry run, not unproductive work.
+
+- Code Reviewer completed review successfully with output and commit
+- Cost: 0 cents
+- Closed done as false alarm
