1"""Live network integration test — 3-hour bootstrap and verification.
2
3Phases:
41. Bootstrap (0-30 min): Reseed, connect to first peers, exchange RouterInfo
52. Exploration (30-90 min): Discover more peers, stabilize routing tables
63. Verification (90-150 min): Attempt .i2p site resolution
74. Sustained (150-180 min): Maintain connections, verify stability
8
9Polls every 60 seconds and logs:
10- Peer count (connected / known)
11- NetDB size
12- Connection status (reachable / firewalled / unknown)
13- .i2p site resolution results
14
15Exit code 0 if: connected to >=5 peers AND resolved >=1 .i2p site
