## Overview

The product is a PHP alumni monitoring and tracer-study web application. Alumni register, maintain profiles and employment data, answer tracer surveys, and use job listings and applications; the Alumni Office approves accounts, manages jobs and applications, communicates with graduates, and analyzes tracer outcomes for reports. The map preserves README capabilities even where their page implementations were not sampled. Relationships are limited to README statements and visible imports/calls; unsampled domain links are omitted rather than inferred.
