`purge` removes every title this store installed, then the playlists, the thumbnail folders and the store's own directories — what a shell script cannot do, because only state.json knows which files were ours. uninstall.sh runs it before deleting the launcher and the store home, and stops if the engine cannot finish, so you are never left with the files but not the engine that knew about them. What survives on purpose: content you put in the store's folder (directories go only when empty), and a playlist that still holds an entry of yours — only items pointing inside the store's content folder are dropped, and a playlist that ends up empty is deleted while one that does not is rewritten without us. A playlist backup is no longer made while purging. It was being created on the uninstall's first touch of a playlist we had written ourselves, which meant the run reported a backup it had just made — and described it as possibly holding entries that were never ours, which was the opposite of true. install.sh and uninstall.sh are POSIX sh now, checked with dash, so `curl … | sh` works where /bin/sh is not bash. The repository moved from the tools org to stores; the old raw URLs still redirect, but every reference is updated. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
