Why are the script rules not working?

Question

Yii

Hello!
There is a Users model. It has two scenarios:

const SCENARIO_NEW = self::SCENARIO_DEFAULT;
const SCENARIO_EDIT = 'edit';

SCENARIO_EDIT is not associated with any rule. The SCENARIO_NEW script is specified for the password attribute.
When specifying the SCENARIO_EDIT script, no validation occurs at all. What could be the reason? It is necessary that the validation pass through all fields except password.
ps There are no scripts for attributes.
pss The scenarios method is not overridden.
