and, why, when I move the app in question into

/Users/redacted/working_dir/

, in which other apps are found (I assume by:

} else {
      for (const auto& path : kSystemSearchPaths) {
        genApplicationsFromPath(path, apps);
      }

      // List all users on the system, and walk common search paths with homes.
      auto homes = osquery::getHomeDirectories();
      for (const auto& home : homes) {
        for (const auto& path : kHomeDirSearchPaths) {
          genApplicationsFromPath(home / path, apps);
        }
      }
