understanding wp doctor custom input file

The wp doctor documentation shows this unclear example for using custom input files to run custom checks.

The input YAML file:

plugin-w3-total-cache:
  check: Plugin_Status
  options:
    name: w3-total-cache
    status: uninstalled

The command and results, per the documentation:

$ wp doctor check --fields=name,status --all --config=doctor.yml
+-----------------------+--------+
| name                  | status |
+-----------------------+--------+
| plugin-w3-total-cache | error  |
+-----------------------+--------+

The precise nature of some values is ambiguous. I’d love to update the documentation but need to understand the details first. My assumptions and questions:

plugin-w3-total-cache: appears to be the name of the check
check: Plugin_Status unclear what this is: perhaps the name of the check for wp doctor’s internal information? I cannot find Plugin_Status in precisely that format anywhere.
options: self-evident
name: w3-total-cache the slug of the plugin being checked
status: uninstalled the status to verify; in the example, because the status in the results is error it appears that that the plugin is installed because uninstalled failed.

If someone can verify my understanding and clarify my confusion, I’ll write it up and submit it.
