Command: go test ./... -count=1
Exit code: 1

Root package integration failures:
- TestClientServerConn
- TestDirectConnect
- TestPipe
- TestExitNode

Shared error:
netmon.New: route ip+net: netlinkrib: operation not permitted

CLI integration failures:
- TestPipeMode
- TestSOCKSClientKey

Observed behavior:
The client could not discover a usable server address while automatic DERP
region probing ran inside the restricted container. The tests timed out and
the later cleanup path reported a nil pointer. The web and webdemo packages
passed in the same full run.

Interpretation:
This is an environment-limited full-suite result. It is not recorded as an
all-pass result, and it does not prove end-to-end transfer between two devices.
