Research direction

Start by locating the SLS reader and its field-selection handling, then trace how LogStore records and tags such as __tag__:__path__ are mapped into output fields. Check existing reader tests or examples for field projection; done means establishing whether tag fields are supported and, if not, defining the required behavior and coverage.
