Widget Coherence for ServiceNow Service Portal

Service Portal widgets MUST have perfect communication between Server Script, Client Controller, and HTML Template. This is not optional - widgets fail when these components don't talk to each other correctly.

The Three-Way Contract

Every widget requires synchronized communication:

1. Server Script Must:

• Initialize ALL data.* properties that HTML will reference
• Handle EVERY input.action that client sends via c.server.get()
• Return data in the format the client expects

2. Client Controller Must:

• Implement EVERY method called by ng-click in HTML
• Use c.server.get({action: 'name'}) for server communication
• Update c.data when server responds
