NEXUS POS — PHASE 19.09.8 PRODUCTION UPDATE
Runtime: 20261001.266

1. Back up the production Nexus files and databases.
2. Install the production bridge ZIP through Super Admin > Updates (or extract it into the Nexus root if you are doing a manual maintenance deployment).
3. Do NOT replace config/database.php. It is intentionally excluded from the production package.
4. core/control_database.php IS intentionally included because it contains platform schema/feature-seeding logic, not deployment credentials.
5. Sign back in to Super Admin after the update.
6. Open Dashboard Cards in the Super Admin sidebar.
7. Choose a Bookshop client and manage Sales, Stock and Attention Centre cards.
8. Bookshop Administrators automatically see every card enabled for their client. Non-admin staff receive individual cards from Bookshop Settings > Permissions.

No separate SQL migration is required. Opening Super Admin runs the safe control-schema ensure routine.
