A target that is reviewed by a coach will now have a checklist, which is a series of steps that a student needs to do as part of completing the target and submitting it. Each step can have an action (like short text, long text, file attachment, etc. ) or no action. Each step in the checklist can be optional as well. The target checklist will be stored as a jsonb field (Target#checklist) with the following shape:

 [  
    {  
      "title": "Upload a file for this task",  
      "optional": "false",  
      "kind": "files"  
    },  
     {  
      "title": "Add a short text about the submission",  
      "optional": "true",  
      "kind": "short_text"  
    },  
        {  
      "title": "Add a long text describing the task",  
      "optional": "false",  
      "kind": "long_text"  
    }  
  ]  
}

The student performs each of these steps using the submission interface and on submission, the response will be stored in a jsonb field TimelineEvent#checklist. An example checklist response :

{  
  [  
    {  
      "title": "Upload a file for this task",  
      "answer": "Link to file",  
      "kind": "upload_file", 
      "review": nil,
    },  
     {  
      "title": "Add a short text about the submission",  
      "answer": "The short text by the student",  
      "kind": "short_text",
      "review": nil,  
    },  
        {  
      "title": "Add a long text describing the task",  
      "result": ""   
      "kind": "long_text",
      "status": "verified" / "failed" / "pending" ,  
    }  
  ]  
}

The valid types for kind: ["files", "link", "long_text", "multi_choice", "short_text"]

The coach in his/her review interface will verify a submission against each of these steps in the checklist. Based on the response from the coach the review field for each checklist item will be updated to nil/true/false

• Target reviewed by a coach must have a checklist. The UI should create a default checklist will the most basic steps for any target (maybe long_text + links + attach links).
