Steps
Call IStats::RequestUserStatsAndAchievements() to pull the current state before making any local changes
Read or update integer/float stats with GetStat/SetStatInt/SetStatFloat, and unlock achievements with SetAchievement
Call IStats::StoreStatsAndAchievements() to push changes to GOG Galaxy's backend -- local changes are not persisted until this call succeeds
Use ClearAchievement with the achievement's API key to reset an achievement during testing
Verify listener callbacks for both retrieve and store operations to detect and retry failures
Known gotchas
Forgetting to call StoreStatsAndAchievements after Set calls means changes are lost on the next session
You must always retrieve stats first -- writing before a successful RequestUserStatsAndAchievements can overwrite server state with stale local defaults
