AngularJS Codebase Modernization Audit

1. Map the module's structure

Given a description of an AngularJS module (controllers, services, directives), diagram what depends on what.

• Every controller's $scope dependencies are identified
• Every shared service and what depends on it is identified

2. Identify a real performance concern

Find at least one genuine digest-cycle performance issue in the described module.

• The issue references a specific real AngularJS performance concept from this course (e.g. watcher count, missing one-time binding)
• A concrete fix is proposed (e.g. applying :: to a specific binding)

3. Propose an incremental migration plan for one feature

Describe how ngUpgrade could migrate one specific feature to modern Angular first.

• The plan identifies which specific feature migrates first and why
• The plan describes how AngularJS and Angular would coexist during the transition

4. Justify the overall strategy

Recommend incremental migration or a full rewrite for the described module, with reasoning.

• The recommendation references real factors from this course (module size, team capacity, architectural health)
• The recommendation is not simply 'keep it on AngularJS indefinitely'
