Basis: the store page was read on 5 Sep 2026; the account does not own this game, so its files have not been read and no anti-cheat, launcher or online service can be detected from them. Store notices have been polled since 3 Sep 2026, so a row with no dated change was already on the page then. Kernel-level is a property of the product (the table and its sources); a missing row means not detected, never none. Data by SteamPeaks.com.
