### What `MessageTraceInput` — the trace query request shape — had no test. This adds 2 tests. ### What is pinned - **the convenience constructor defaults the custom trace topic to `null`** (the broker default); - the full constructor carries the custom trace topic. ### Verification - New tests on unmodified code: **2/2 green**, checkstyle clean. - Discriminating mutation: the convenience default changed to empty string (red — `null` is the broker-default signal, not ``). - Restored: 2/2 green. Test-only change; no product code touched. -- This is an automated message from the Apache Git Service.
