Sending a post request to update

{
  "completed": true
}

only updates that field

{
  "completed": true,
  "completed_at": null,
  "created_at": "2026-01-01T17:31:38.129044",
  "description": null,
  "id": 40,
  "principles": [],
  "project_id": null,
  "tags": [],
  "title": "Test task",
  "updated_at": "2026-01-01T17:31:38.267634",
  "user_id": 2
}

note the "completed at" field is null.

Instead of sending a post request to update, make a new endpoint, something like tasks/{{id}}/complete so the logic to complete can all go in there. Otherwise we'll have to jam additional "update this field if this" logic into the update endpoint.
