From 44cdde8b005c0bee5bec52b5d38ba50961b76e5c Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 8 Mar 2026 20:09:32 +0000 Subject: [PATCH 1/2] Skip conversion when converted file already exists in source library MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When a device requires a different file type (e.g. mp3) and the source library already contains a file with that extension (e.g. track.mp3 alongside track.aiff), convert_file would still attempt to transcode the original. Add a check so that if the source directory already has a file with the target extension, the conversion is skipped — the existing source file will be picked up by the sync loop and copied directly instead. https://claude.ai/code/session_012Aej1UZqDBLaQW2rZ799zo --- lib/wavesync/scanner.rb | 5 ++ test/wavesync/scanner_test.rb | 91 +++++++++++++++++++++++++++++++++++ 2 files changed, 96

definitions Follow the same pattern as analyzer_test.rb: require real Audio, UI, and Scanner files, then use mocha class-level stubs to control behavior rather than defining fake stub classes inline.
