-Go version: 1.26.4. Testing uses `testify` (assert/require). Tests are table-driven with subtests. Mock pattern: embed `mock.Mock` and call `m.MethodCalled()` (see `k8s_test.go`). Protocol packet tests use hex fixture files in `testdata/` (e.g., `handshake-status.hex`). Test setup for route tests calls `NewRoutes()` and restores the global `Routes` singleton with defer.
