Mogador Gaming Club

Members book a station for a one-hour block, say how many people are coming and pick a game from the club's library. Behind that, an admin area used on the floor: who's on which console tonight, one-tap check-in, no-show marking, slot generation, controller inventory, memberships. Three stations today — two PS4s and a PS3 — on Thursday and Friday evenings at Dar Souiri.

The core constraint isn't capacity, it's exclusivity: one party per console per block. That lives in Postgres as a unique index plus a FOR UPDATE lock inside the booking function, never in application code — two people tapping the same 18:00 slot is the failure that loses a member. Same for membership and seat limits. The app sends intent; the database decides. The lock was proved under real concurrency rather than sequentially.

The admin dashboard is what will answer whether the club is viable before signing a lease — occupancy, no-show rate, refused demand.
