+# Issue #680 Verification — Fleet-Ops Genome Already Implemented
+
+**Date:** 2026-04-14  
+**Verified by:** Sprint auto-implementation (issue #807)  
+**Status:** ✅ Already implemented on `main`
+
+## Summary
+
+The fleet-ops genome deliverable requested in issue #680 already exists on `main`.
+This document records the verification evidence and closes the stale issue.
+
+## Existing Artifact
+
+- **Genome document:** `genomes/fleet-ops-GENOME.md`
+- **Regression test:** `tests/test_fleet_ops_genome.py`
+
+The genome document contains:
+- Project overview grounded in a fresh clone of `fleet-ops` at commit `38c4eab`
+- Mermaid architecture diagram
+- Structural analysis of Ansible playbooks, Python microservices, cron jobs, and docker-compose sandbox
+- Key abstractions, API surface, test coverage gaps, security considerations, and deployment notes
+- Concrete metrics: 97 source files, 12 test files, 29 config files, 16,658 lines
+- Test results: 158 passed, 1 failed, 2 errors
+
+## Prior PR Trail (Closed Unmerged)
+
+The issue remained open because earlier linking PRs were closed without merging:
+
+- **PR #697** — closed unmerged
+- **PR #770** — closed unmerged
+
+Since the artifact landed on `main` through other means, those PRs became stale.
+
+## Verification Commands
+
+```bash
+# Confirm artifact exists
+ls -la genomes/fleet-ops-GENOME.md
+ls -la tests/test_fleet_ops_genome.py
+
+# Run regression tests
+python3 -m pytest -q tests/test_fleet_ops_genome.py
+
+# Syntax check
+python3 -m py_compile tests/test_fleet_ops_genome.py
+```
+
+## Conclusion
+
+No new content is needed. Issue #680 is resolved by the existing implementation.
+This PR adds the verification doc and a test to lock the evidence trail.
