Subject: [PATCH] Cleanup: debug()-Endpoint entschachtelt
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Die lange verschachtelte current_progress-Ternary in /debug durch klare
lokale Variablen ersetzt; redundante 'if progress'-Checks entfernt
(das Dict wird ohnehin nur bei vorhandenem Progress gebaut). Doppelter
os.path.exists-Aufruf zusammengefasst. Verhalten unverändert.
