What is the correct order of execution for client-side code in ServiceNow?

Explanation:
The sequence is about how ServiceNow loads and runs different client-side pieces in a form, with dependencies in mind. UI Script provides global helpers and utilities, so it must load first to be available to every other client-side code. After those utilities are ready, the main form logic runs through a Client Script (onLoad, onChange, onSubmit) that implements the core behavior of the form and can rely on the functions defined in the UI Script. UI Policy Actions are the actual changes applied to fields (such as making a field visible, mandatory, or read-only) and should occur after the policy conditions have been considered. The UI Policy Script contains the policy’s conditional logic and is evaluated in this stage to determine when those actions should apply, finalizing the policy-driven behavior for the current state of the form. This order ensures dependencies are met and policy-driven UI changes reflect the most up-to-date form state.
