Runmodes are chosen as the startup artifacts are interpreted, and the quickstart jar filename is a built-in way to convey which runmodes should apply. The startup logic looks at the jar’s name to extract runmode tokens, so simply by using a jar whose filename encodes the desired runmodes you control the instance’s behavior without editing config files. This is why identifying the runmode from the quickstart jar filename is the true statement. The other options are not reliable guarantees: runmodes aren’t fixed to author by default, sling.properties alone doesn’t determine the runmode, and while a -r option exists, it isn’t universally the sole or absolute source compared to the filename-based hint in typical startup scenarios.
