• Event: reusable definition such as “Morning Flow”.
• Recurring series: weekly generation rule with start and end dates.
• Event instance: concrete occurrence with a start, end, capacity, status, and audience.
• Product: something purchasable, such as a subscription, class pass, workshop, or drop-in.
• Entitlement: a user’s right to book, potentially limited by remaining classes or expiry.
• Booking: a reservation connecting an attendee to one instance and its payment or entitlement source.
• Payment: purchase attempt and provider result.

Moved or cancelled recurring occurrences are recorded as instance exceptions so the original series remains understandable.
