Why This Matters

this mixin is simple but still easy to break because it returns raw dicts.

Read First

• app/services/tracer_client/tracer_logs.py

Scope

1. Add direct tests for parameter construction.
2. Test both the trace_id and run_id call paths.
3. Keep the tests small and focused.

Tests / Coverage

• tests/services/tracer_client/test_tracer_logs.py
• cover default size
• cover trace_id precedence
• cover run_id fallback

Acceptance Criteria

• parameter-building behavior is covered directly
• the mixin can be refactored safely later
• the tests stay lightweight
