Walkthrough

The change adds a DNS options test. The test validates custom-port and standard-port nameservers in BaseResolvers.

Nameserver port validation

Layer / File(s) Summary
Resolver options test
libs/dnsx/day3_w10_nsport_test.go
Adds TestOptionsCustomNameserverPortValidation. The test checks two resolver entries and verifies 127.0.0.1:8053 remains present.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🔵 Low · up to 459a1

This change only adds DNS resolver-option test coverage. The test does not yet prove that the standard-port nameserver is preserved, creating a minor validation gap before merge.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert the standard-port resolver as well.

The test checks the custom-port entry but does not verify "1.1.1.1:53". A wrong second resolver would still pass because only the slice length is checked. Add an assertion for both configured entries.

Proposed fix
 	assert.Equal(t, 2, len(opts.BaseResolvers))
 	assert.Contains(t, opts.BaseResolvers, "127.0.0.1:8053")
+	assert.Contains(t, opts.BaseResolvers, "1.1.1.1:53")
