Use when deciding what a paying customer may actually use — the access record that Digistore24 events write to, and the one function the rest of the app asks. Covers why access is not the order table and not the subscription table, how to gate a page or a feature, upgrades where somebody holds two plans at once, and a paused plan after a missed payment. Use it whenever the user asks how to check if someone has paid, how to lock a feature behind a plan, or reports that a cancelled customer lost access too early.
