How to determine which snap is active as returned from /v2/snaps?select=all

snapd

If you get all the installed revisions of a snap, i.e.:

$ curl --unix-socket /run/snapd.socket 'http://localhost/v2/snaps?select=all&snaps=core' | jq .

you get something like:

{
  "type": "sync",
  "status-code": 200,
  "status": "OK",
  "result": [
    {
      "id": "99T7MUlRhtI3U0QFgl5mXXESAiSwt776",

    }
  ],
  "sources": [
    "local"
  ]
}

How does a snapd client determine which one of these is active (as would have been returned without the select=all)?

afaik "status:" "active" vs just "status": "installed"

Thanks, I was staring at them and just didn’t notice that difference…
