      summary: PR analysis data
      description: Returns the app size analysis results and any performance test analysis results, as well as PR comments. This endpoint should be used in favor of `/comment`, as it provides a superset of the data. Further, instead of returning a 4xx response when it's not ready yet (which is what /comment does), it will return a 200 response and indicate within the JSON which jobs are still in progress. Must specify either `sha` or `emergeId`.
