A constraint-based course scheduler for 7 Purdue engineering majors. Models each degree as a dependency graph, solves for the fastest path to graduation, and mathematically verifies the result against a combinatorial lower bound, so "optimal" isn't just a claim. Includes a 3D orbitable critical-path view, weekly timetable with .ics export, and GPA projection. No account, no framework, runs entirely in your browser.
