forked from unom/punktfunk
The visible "Punktfunk" shortcut's Steam appId is cached in SteamUI localStorage, which lives in Steam's CEF profile — so it survives a plugin uninstall/reinstall. Deleting the shortcut left the key dangling; on the next mount ensure*Shortcut recalled the dead appId, took the reuse branch, and ran SetShortcut* against a non-existent id (silent no-ops). AddShortcut was never reached, so the entry never came back. The same stale-reuse also made the hidden stream shortcut RunGame a dead gameid. Verify the remembered appId still maps to a live shortcut via appStore.GetAppOverviewByAppID before reusing it; a confident miss falls through to AddShortcut. When appStore is unavailable, assume it exists so a false negative can't spawn a duplicate library entry. Also add a "Recreate library shortcut" recovery button to the QAM About section (recreateShortcuts): drops any dead cached keys and re-ensures. Covers deleting the shortcut without reinstalling, where no mount fires the self-heal. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
