From 38d21cf2e008b7fba34d6ee0e321c12047dd6e23 Mon Sep 17 00:00:00 2001 From: Honey Date: Sun, 21 Jun 2026 14:10:08 +0200 Subject: [PATCH] fix(backend): remove title keyword filter for Japanese tracks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Japanese Art Tracks on YTM/YouTube are often romanized ("Souiunatsu" for "そういう夏") — the Japanese keyword filter in --match-filter always rejected the correct video. Channel + duration are sufficient quality gates for JP tracks.
