Walkthrough

The pull request adds a Go test that verifies an RFC 5424 syslog message starts with the expected priority and version header.

Changes

Syslog header validation

Layer / File(s)	Summary
RFC 5424 header test pkg/server/syslog_rfc5424_test.go	Adds TestSyslogRFC5424MessageHeader to verify that a sample message starts with <165>1.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: 🟠 High · up to 4e82a

The newly added syslog test file has a malformed string literal, so the server test package no longer compiles and its test suite cannot run. This should be corrected before merging; no production behavior is otherwise changed.

Escape the structured-data quotes so the test compiles.

gofmt reports expected ';', found abc at line 9. Use a raw string literal or escape the inner quotes.

Proposed fix

-	rawMsg := "<165>1 2026-09-10T20:00:00.000Z host.example.com app - ID47 [interactsh@123 token="abc"] probe message"
+	rawMsg := `<165>1 2026-09-10T20:00:00.000Z host.example.com app - ID47 [interactsh@123 token="abc"] probe message`
