Adminator	fb44ec7afe	student_id-FK-Migration Stufe 1+2: Name-Joins -> student_sessions.student_id ... - student_sessions: neue Spalte student_id (+Index), backfilled aus (class_id,display_name) - Session::createStudent setzt student_id (per Lookup, falls nicht uebergeben) - alle Joins students<->student_sessions von display_name auf student_id umgestellt: Benchmark.php, live.php (5x), results.php (4x + runs), modules.php, profile.php, progress.php (answers+runs) - verlustfrei verifiziert (alt-Join == neu-Join, class 99/102) Robuster gegen Umbenennung/Doppelnamen, indexierbare Joins.
