From b431107abd0869bd4282fc58922efbb671f814ee Mon Sep 17 00:00:00 2001 From: SBCrumb Date: Fri, 26 Sep 2025 13:39:41 -0400 Subject: [PATCH] feat: Complete clean TV NFO processing implementation v2.0.0 - New EpisodeNFOManager class with video filename matching - NFO files now match video filenames instead of S01E01.nfo format - Clean TVSeriesProcessor with proper Sonarr API integration - Proper date lookup: database -> Sonarr import history -> airdate fallback - Updated manual scan endpoint to use new clean processor - Removed all migration logic and nfo_migration_required sources This is a complete rewrite of TV episode processing with focus on: 1. NFO filenames matching video files 2. Proper dateadded field population from Sonarr 3. Clean separation of concerns 4.
