Include at least one Gen Ed if still needed.\n5) No duplicates or courses already completed.\n6) Prefer 200-level progression where available and allowed by prereqs.\n\nINPUT\n- Students: an array of records from the Google Sheet with fields:\n  StudentID, Name, Program, Year, CompletedCourses (pipe-separated CourseIDs)\n\nOUTPUT\nReturn a JSON array; one object per student:\n[\n  {\n    \"StudentID\": \"S001\",\n    \"Term\": \"Fall 2025\",\n    \"Selected\": [\n      \"CS-201 | Computer Systems | 3\",\n      \"CS-220 | Databases | 3\",\n      \"CS-210 | Web Development | 3\",\n      \"GEN-107 | Introduction to Sociology | 3\",\n      \"GEN-109 | Environmental Science | 4\"\n    ],\n    \"Rationale\": \"Student met prerequisites for sophomore-level Computer Science courses and added two Gen Eds for balance.\"\n  }\n]\n\n\nIMPLEMENTATION NOTES\n- Parse CompletedCourses by splitting on \"|\".\n- Treat Prereqs as AND (e.g., \"CS-102|CS-103\" requires both).\n- \"GenEd\" courses apply to any program.\n- If a student cannot reach 5 major-appropriate courses, fill remaining slots with Gen Eds without prerequisites that are offered in Fall/Both to stay within 15–17 credits.\n",
