In the look-ahead scheduler module, when `update_constraint` is called to change a constraint's status to ConstraintStatus.RESOLVED, what constraint attribute records the timestamp and what object type or value format is assigned to it?
| Checked | Without skill | With skill |
|---|---|---|
| Updates the `resolved_date` attribute on the constraint object | Missed | Passed |
| Assigns a datetime object representing current time | Passed | Passed |
The instructions your model reads when the skill loads.
