NEXUS POS — PHASE 19.09.4 PRODUCTION UPDATE
Runtime: 20260930.262

1. Back up the production Nexus files and databases.
2. Upload/extract this update over the Nexus project root.
3. The production update does NOT include config/database.php, so hosting database credentials remain untouched.
4. Let the Nexus updater remove the obsolete High-End Hospitality files listed in nexus-release.json delete_paths.
5. Sign out and sign back in after deployment.
6. Create a fresh Restaurant test client first and verify Orders → Kitchen → Cashier before using it for a live client.

FAILED OLD RESTAURANT ATTEMPT
If an earlier failed Hospitality setup left a partial client database, remove ONLY that failed Restaurant database (or use a fresh database name) before retrying. Never remove the Nexus control database.

This release restores Restaurant R7 and preserves all Bookshop Phase 19.09–19.09.3 changes.
