Nexus POS — Bookshop Savings Phase 19.10.4 (runtime 20261020.276)
1. Back up your installation and both databases.
2. Install the LOCALHOST UPDATE ZIP over the Nexus project root, preferably from Phase 19.10.3.
3. Refresh the browser once (Ctrl+Shift+R).
4. Sign in as Bookshop Administrator. Open Settings > Expenses to seed/setup presets.
5. Open Accounts > Payment Registers. Test saving with a test amount in an open business day.
6. Grant reg.saving and (if necessary) reg.saving.reverse to selected staff in Bookshop Settings > Permissions.
7. Verify existing receipt animation, Cash Out, and P&L still work before production.
No manual SQL import required. Previous savings entered under Expenses require a separate audited reclassification process, not an automatic database edit.
