/**
 * FIX 2026-08-31 — bug sync attendance e-jurnal → violation alpha:
 * 1. violation lama tidak pernah dihapus saat push koreksi tanpa alpha ($alphaDate null)
 * 2. totalAlpha dihitung untuk semua siswa memakai tanggal global → salah siswa/tanggal
 *
 * Kasus nyata: XII TKJ 3 26-08 HENDIK (sakit) / RAMADANI & RHEDO (hadir) dicatat bolos.
