Close FRE-5081: mark ghost run 14acabf9 evaluation as false positive

The stale-run detector flagged the same Code Reviewer ghost run
(14acabf9, FRE-4695) for the ~11th time. Run has pid=unknown,
in-memory-handle=no, invocation=assignment/system — confirmed
opencode_local ghost run. Documented in Code Reviewer's AGENTS.md
as expected behavior. Root fixes tracked in FRE-4990 and FRE-5042.

 ## Status
 The dedup fix from FRE-4846/FRE-4966 does NOT prevent duplicate evaluations for already-resolved originFingerprints. Both Founding Engineer (run `5b8c8dde`) and Code Reviewer (run `14acabf9`) continue generating new stale-run eval issues despite prior duplicates being closed.
 
-Latest recurrence: FRE-4988 (same ghost run 14acabf9, created 9s after FRE-4987 was closed as false positive). FRE-4966 deployed fix commit `cda0f3dd` but did not prevent this. Follow-up tracked in FRE-4990.
+Latest recurrence: FRE-5015 (same ghost run 14acabf9, 16th+ instance). FRE-4966 deployed fix commit `cda0f3dd` but did not prevent this. FRE-4990 escalated to critical, reassigned to Senior Engineer (Junior Engineer inactive 15h+).
 
 ## Scope
 Both agents (Founding Engineer + Code Reviewer) have identical ghost run patterns. Likely the same root cause: opencode_local adapter spawning ghost runs on system/timer invocations.
