Preparing a clear audio handoff

[Gracejify]

My archive contains generated song drafts exported at different points over the past few months. A few titles appear on several exports, with filenames that do not explain the differences. My first step is preserving the originals and recording the purpose of every proposed revision. A phrase I used in my search was remove suno artifacts but that label does not prove a revision improved the recording. Is a folder structure, a filename convention, or a spreadsheet easiest to maintain over time? I also need a way to distinguish a format conversion from a change made to the audio itself. For each file I can record the export date, source version, format, and reason for keeping it. I would rather maintain a small useful record than a complicated system I stop updating. A practical naming example that remains understandable a year later would be helpful.
