+# Issue #680 Verification — fleet-ops Genome Already Implemented
+
+**Date:** 2026-06-20  
+**Status:** VERIFIED — deliverable exists on `main`  
+**Closes:** #680, #807
+
+## Summary
+
+Issue #680 requested creation of a curated genome document for the `fleet-ops` repository. This deliverable already exists on `main`:
+
+- **Artifact:** `genomes/fleet-ops-GENOME.md`
+- **Regression test:** `tests/test_fleet_ops_genome.py`
+
+## Evidence
+
+| Check | Result |
+|---|---|
+| `genomes/fleet-ops-GENOME.md` exists | ✅ |
+| Contains all required sections | ✅ |
+| Contains grounded findings (real files, metrics) | ✅ |
+| Document is substantial (≥120 lines, ≥7000 chars) | ✅ |
+| `tests/test_fleet_ops_genome.py` exists | ✅ |
+| Tests pass | ✅ 3 passed |
+
+### Verification command
+
+```bash
+python3 -m pytest -q tests/test_fleet_ops_genome.py
+```
+
+## Prior PR Trail (closed/unmerged)
+
+| PR | Status | Notes |
+|---|---|---|
+| #697 | Closed | Original genome delivery PR; closed unmerged |
+| #770 | Closed | Second attempt; closed unmerged |
+
+Both PRs were closed without merging, which left issue #680 open despite the content already being on `main`. This verification document closes the stale issue by recording the existing implementation rather than regenerating duplicate content.
