NEXUS POS — PHASE 19.09.9 PRODUCTION UPDATE
Runtime: 20261001.267

1. Back up production Nexus files and databases.
2. Install the production bridge ZIP through Super Admin > Updates, or use Manual Maintenance and extract it into the Nexus root.
3. config/database.php is intentionally excluded from the production bridge.
4. Sign out and sign back in after the update so the Bookshop session-shop state starts cleanly.
5. Before choosing a shop, a multi-shop Bookshop Admin Dashboard should show all accessible shops.
6. Open an operational navigation item and choose a shop.
7. Return to Dashboard: only the selected/locked shop must be visible, including Sales, Stock and Attention Centre.
8. Other shop figures and Shop Comparison panels must not be shown while that session shop is locked.
9. The shop remains locked until logout. After logout/login, Admin may choose another shop.

No SQL/database migration is required.
