# duplicate_checker.py v5.0
|
|
# Build timestamp is injected into logfile name.
|
|
|
|
# --- FEATURES v5.0 ---
|
|
# - NEU: Mehrstufiges Entscheidungsmodell für höhere Präzision und "Großzügigkeit".
|
|
# - Stufe 1: "Golden Match" für exakte Treffer.
|
|
# - Stufe 2: "Kernidentitäts-Bonus & Tie-Breaker" zur korrekten Zuordnung von Konzerngesellschaften.
|
|
# - Stufe 3: Neu kalibrierter, gewichteter Score für alle anderen Fälle.
|
|
# - Intelligenter Tie-Breaker, der nur bei wirklich guten und engen Kandidaten greift.
