Let me clean up the test record and do a final verification:Let me verify the complete state one more time:Rollout complete.\n\n**Summary of actions:**\n\n1. **Created `/opt/rollout/v2.py`** - Implements all required endpoints (`/health`, `/version`, `GET/PUT /records/`) using the same SQLite database at `/var/lib/rollout/records.sqlite3`\n\n2. **Started `rollout-v2.service`** - Listens on `127.0.0.1:8082`, shares the same database with v1 so all existing records are immediately accessible\n\n3. **Verified v2 endpoints** - Health returns `ready`, version returns `v2`, existing records (`customer-alpha-73c`, `customer-beta-a19`) return correct values\n\n4. **Atomically switched upstream** - Wrote `8082` to `/var/lib/rollout/upstream`, proxy now routes all traffic to v2\n\n5. **Verified zero-downtime** - All services (`rollout-v1`, `rollout-v2`, `rollout-proxy`) remain active and running. Public endpoint at port 8080 serves v2 responses. Existing records preserved and accessible.\n\nThe rollout is complete with no externally visible outage. v2 survives restarts (verified) and uses the shared database so records persist across host reboots.", "resource_units_used": 1, "input_tokens": 208740, "output_tokens": 4185, "cost_microusd": 91866 }, "gemini": { "territory": "rollout-two", "model": "vercel/google/gemini-3.8-flash", "running": false, "successful": false, "failure_source": "player", "terminal_state": "incomplete", "terminal_detail": "rollout-one reached durable first; build ended at the frozen clock", "resource_units_used": 1, "input_tokens": 101701, "output_tokens": 17718, "cost_microusd": 172533 }, "mercury": { "territory": "rollout-three", "model": "vercel/inception/mercury-2.5", "running": false, "successful": false, "failure_source": "player", "terminal_state": "incomplete", "terminal_detail": "rollout-one reached durable first; build ended at the frozen clock", "resource_units_used": 1, "input_tokens": 14378, "output_tokens": 776, "cost_microusd": 692 } }, "winner": "rollout-one", "finish_reason": "first durable deployment", "infrastructure_failures": 0, "last_sequence": 45, "elapsed_ms": 115890 }
