# Ghost Run Investigation

## Issues
- FRE-4849: Investigate Founding Engineer recurring ghost/stale run pattern (in_progress, Senior Engineer)
- FRE-4846: Deploy stale_active_run_evaluation fix (done)

## 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.

## 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.

## Known Ghost Runs (Active Issues Generated)
- Code Reviewer run `14acabf9` (FRE-4695): generated FRE-4981 through FRE-4988 (8 issues)
- Founding Engineer run `5b8c8dde`: repeated pattern
