Branch feature/split-multiple-users, 18 commits against main (54 files, +2914 / −993).

Request money: split between several users

• Request money from several users at once and split it by factor, percentage or fixed amount; unset shares are calculated automatically and can be reset per person; optionally include your own share
• The simple form stays the default, splitting is enabled via the "Single / Group" toggle; negative automatic shares are marked with a warning icon

Amount fields: dot and comma

• New DecimalInput component replaces type="number": accepts both dot and comma as decimal separator; at most 4 decimal places are shown

Keycloak / LDAP

• Old LDAP usernames ("firstname.lastname") are replaced with the Keycloak display name ("Firstname Lastname") on Keycloak login and once at server start; other names are left unchanged
• Admin rights (LABEATS_ADMIN) are synced with the user's groups on every Keycloak login; without a groups claim the stored value is kept

Sign-out after update

• Every build gets a SESSION_BUILD_ID; sessions from older builds are rejected, so every container update signs all users out once. Restarting the same image signs nobody out.

Group orders

• Individual items are only reserved (transaction type 4, "reserved purchase") and charged when the order is settled; they can be cancelled until the order closes. Reservations count towards the balance check for users who are not creditworthy.
• Shopper: "I'm going shopping" / sign off, set automatically when the order closes or is settled or by a new button; only one Person can be the shopper but you can take it from some else.
• Category filter for the order window (admins and shopper)
• Reworked settlement: adjustable prices for individual items, "Total / group items only" toggle, separate button; admins can always revert a settlement, the person who settled it for 2 h
• Recurring orders: "hours before" (ordersStartsAt, default 72 h)

Deposit

• Items can have a deposit amount; the buy tab shows a separate "+ deposit" button for it, booked as a regular purchase without category markups
• Deposit as a column in the inventory; inventory sortable by name, price, deposit and account

Statistics

• Profile: tiles for ranking, total spending, procurement, weekly/monthly average, deposit and top 3 items
• New admin page "Statistics" with totals only: revenue, active users, deposit, outstanding balances, overdrafts, best-selling items

Notification dot

• Red dot on the account tab (on mobile on the menu icon) when someone has collected money from you; it disappears once the account page has been opened

Minor UI fixes

• Top-up button in the header uses the nav color,
• filter buttons in the buy tab are consistent and persistent,
• the creditworthy checkbox in the user popup resets when switching users
• changed & more consistant grey shades

Cleanup and booking bugs

• Security: removed user.getCtx, which returned the LDAP bind password without login
• Undo now also books the item price/deposit back from the clearing account
• Undo, transfers, closing/reverting group orders are protected against double execution
• Fees without a target clearing account are rejected instead of being lost; no negative prices when closing a group order
• LDAP user data no longer logged, cron errors are logged; dead code and debug logs removed; npm audit fix
• README: instructions for local development

Deployment notes

• 4 migrations, applied automatically via prisma migrate deploy in the entrypoint:
  • add_orders_starts_at_to_template: new column, default 72
  • add_item_deposit: new column, default 0
  • add_grouporder_shopper_and_filter: rebuilds the GroupOrder table and backfills the shopper of closed orders with the recipient of the settlement.
  • add_user_retractions_seen_at: marks all existing money collections as seen so nobody sees a stale red dot after the update
• All users are signed out once after deployment (new build ID).
• src/instrumentation.ts renames old LDAP usernames once at server start. This is transitional code and can be removed (together with syncKeycloakNames in src/server/syncKeycloakNames.ts) once all accounts have been migrated. Renaming on login is not affected.
• Individual items that were still charged directly at purchase before the update are booked back from the clearing account when a settlement is reverted, so old orders remain revertible.
• The entrypoint script does not abort if a migration fails: the app still starts, but with an incompletely migrated schema. Check the output of prisma migrate deploy in the container log after deploying.

Walkthrough

The pull request updates group-order purchasing and billing, deposit purchases, money requests, account statistics, and authentication. It also changes database fields, development setup, session validation, and interface views.

Changes: Group-order lifecycle

Layer / File(s)	Summary
Group-order data and scheduling prisma/schema.prisma, prisma/migrations/*, src/components/Forms/GrouporderTemplateForm.tsx, src/pages/api/cron/trigger.ts, src/pages/admin/grouporders.tsx	Group orders gain shopper and category-filter fields. Templates gain a start offset and default category. The cron job calculates order creation timing from template deadlines.
Reservations and group-order controls src/server/api/routers/groupOrders.ts, src/server/api/routers/items.ts, src/pages/grouporders/*, src/components/FormElements/GroupOrderDetailView.tsx, src/components/PageComponents/TransactionList.tsx	The endpoints and pages add quantity-aware reservations, shopper and category controls, reservation cancellation, separate item lists, and shopper details. Transaction type 4 receives a label.
Split billing and revert operations src/components/FormElements/GroupOrderSplit.tsx, src/helper/generalFunctions.ts, src/helper/globalTypes.ts, src/helper/generalFunctions.test.ts	Split billing supports group and individual costs, payer selection, and price overrides. Shared helpers calculate splits and check the revert window. Closing checks the expected total and books reservations.
Category and reservation fee data prisma/schema.prisma, prisma/migrations/*, src/helper/dataProcessing.ts, src/server/api/routers/groupOrders.ts	Transactions store category markup and destination snapshots. The migration backfills fee records for eligible group-order transactions.

Change: Feature

Deposits and item purchasing

Layer / File(s)	Summary
Deposit fields and purchase flow prisma/schema.prisma, prisma/migrations/*, src/components/Forms/ItemForm.tsx, src/components/General/BuyItemCard.tsx, src/pages/buy.tsx, src/server/api/routers/items.ts	Items gain a deposit field. The item form edits it, and the purchase interface and item router support deposit-only purchases.
Inventory sorting src/components/PageComponents/InventoryOverview.tsx	The inventory table sorts by name, price, deposit, or account, and displays positive deposits.

Transfers and retraction requests

Layer / File(s)	Summary
Group requests and transaction updates src/components/PageComponents/GetMoney.tsx, src/pages/split.tsx, src/server/api/routers/transactions.ts, src/server/api/routers/user.ts, src/server/helper/dbCallHelper.ts, prisma/schema.prisma, prisma/migrations/*	The request form supports group participants and split modes. The retraction mutation accepts multiple requests. Transaction operations account for reserved funds, and user endpoints track unseen retractions.
Retraction notices and decimal inputs src/pages/account.tsx, src/components/Layout/Header.tsx, src/components/General/DecimalInput.tsx, src/components/Forms/CategoryForm.tsx, src/components/PageComponents/SendMoney.tsx, src/pages/admin/clearingAccounts.tsx	The account page marks retractions as seen, and the header displays the unseen count. DecimalInput replaces native numeric inputs in several forms.
User balances and form state src/pages/all-users.tsx, src/components/PageComponents/UserOverview.tsx	The user overview adds search, sorting, balance formatting, and request states. The selected-user form receives a key based on the selected user.

User and admin statistics

Layer / File(s)	Summary
Statistics calculations and queries src/server/helper/statistics.ts, src/server/helper/statistics.test.ts, src/server/api/routers/transactions.ts, src/server/api/routers/user.ts	New helpers calculate averages, date-bounded totals, and item rankings. User and admin queries return sales, deposit, activity, balance, and ranking data.
Statistics cards and navigation src/components/PageComponents/RankingCard.tsx, src/pages/me/index.tsx, src/pages/admin/stats.tsx, src/components/Layout/Header.tsx	The profile and admin pages display statistics cards and item rankings. The header adds a link to the admin statistics page.

Authentication and identity synchronization

Layer / File(s)	Summary
Session build and admin claims next.config.mjs, src/proxy.ts, src/server/sessionBuild.ts, src/server/sessionBuild.test.ts, src/server/auth.ts, src/server/syncKeycloakAdmin.ts, src/server/syncKeycloakAdmin.test.ts	JWTs record a build ID, and the proxy checks it. Keycloak group claims determine and synchronize admin status.
Keycloak name synchronization src/instrumentation.ts, src/server/auth.ts, src/server/syncKeycloakNames.ts, src/server/syncKeycloakNames.test.ts, src/server/ldap.ts	Sign-in and Node.js instrumentation run name synchronization. Helpers extract Keycloak names and update LDAP-style names. LDAP logs no longer serialize user records.

Runtime setup and shared presentation

Layer / File(s)	Summary
Development and database setup .env.example, README.md, eslint.config.mts, scripts/screenshots/seed.ts, src/server/db.ts	The README adds development setup instructions. SQLite URLs pass through unchanged, screenshot seeding uses the selected path, and ESLint ignores .next/**.
Shared layout and card styling src/styles/globals.css, src/components/Layout/Layout.tsx, src/components/General/BuyItemCardBig.tsx, src/components/PageComponents/TransactionList.tsx, src/pages/top-up.tsx, src/components/Layout/Header.tsx	The root background variable is added, the layout uses minimum viewport height, and selected cards and navigation styles change.

Hey,
danke für die Erweiterungen!

Ein paar Dinge:

1. Category fees can disappear before settlement — P1

The new flow delays charging a reserved item until the group order is settled. To calculate its fees later, settlement reads the categories associated with that purchase.

However, the category relationship can point to only one purchase. Buying another item with the same category moves that relationship to the newer purchase.

For example:

1. Alice reserves an item with a €0.50 category fee.
2. Bob reserves another item using that category.
3. The category association moves from Alice’s reservation to Bob’s.
4. At settlement, Alice’s reservation no longer has the category information needed to charge her fee.
   An ordinary purchase can also displace the association. The result is missing charges and too little money credited to the clearing account. Previously, fees were calculated immediately, before a later purchase could change the relationship.

Suggested fix: save the applicable fees and their destination accounts separately for every reservation, so subsequent purchases cannot change them.

2. A reservation can arrive after the order has settled — P2

Checking whether an order is open and creating the reservation happen separately. Another request can close and settle the order between those steps.

For example:

1. Alice clicks to reserve an item; the server checks that the order is open.
2. The shopper closes and settles the order.
3. Alice’s request resumes and creates the reservation without checking again.
   That reservation missed settlement, but cancellation is now blocked because the order is closed. Its amount can remain reserved against Alice’s available balance, reducing what she can spend or transfer.

Suggested fix: make checking the order’s state and creating the reservation one coordinated operation that cannot race with closure or settlement.

3. Editing a category can empty an order’s item list — P2

Editing a category creates a replacement category with a new ID and moves its items to that replacement. An existing group order’s filter still points to the old ID.

For example, an order is filtered to “Drinks.” An admin edits that category. All drinks now belong to its replacement, while the order continues filtering by the old category. Consequently, no items match, and the old category also disappears from the selector.

This disrupts ordering until the shopper or an admin resets the filter; it does not delete the items.

Suggested fix: update affected order filters when replacing a category, or have filters refer to a category identity that remains stable across edits.

4. Block settlement when the total is too low.
   If individual reservations total €10 but the shopper enters a €5 overall receipt total, the interface marks the amount invalid yet still allows settlement. The shared portion is clamped to zero, and €10 is charged anyway. Disable submission for this case and validate the expected total on the server.

Inline comments:
Review comments at @src/components/FormElements/GroupOrderSplit.tsx:
- Around line 426-429: Disable the “Abrechnen” button in the close-group-order
flow when totalAmount is NaN or totalAmountTooLow is true. Update the button
that calls setCloseGroupOrderModalOpen so invalid or insufficient totals cannot
be confirmed.

Review comments at @src/components/Forms/ItemForm.tsx:
- Around line 132-140: Update the deposit field’s onChange handling in
Controller to convert an empty input value from DecimalInput to undefined or 0
before validation, while preserving normal numeric values.

Review comments at @src/instrumentation.ts:
- Line 6: Remove the await syncKeycloakNames(prisma) call from the server
startup flow in instrumentation.ts, and move the account rename work into a
one-time batched migration that does not block server readiness on each restart.

Review comments at @src/server/api/routers/groupOrders.ts:
- Around line 421-424: Update the reserved-buy fee calculations in close and
revertClosed to use mapping.item.categories instead of mapping.categories, and
include each mapping’s item with its categories in both queries that load the
orders or transaction. Keep the existing fee calculation inputs and other query
includes unchanged.

Review comments at @src/server/db.ts:
- Line 15: Update the database URL handling in the Prisma configuration so
existing installations using DATABASE_URL="file:./db.sqlite" continue resolving
to prisma/db.sqlite; preserve this legacy path behavior rather than silently
opening a different project-root database.

Review comments at @src/server/syncKeycloakAdmin.ts:
- Around line 11-12: Update isAdminFromGroups to return undefined when groups is
not an array or contains any non-string entry; preserve the existing admin-group
check for arrays containing only strings so malformed claims do not revoke admin
access.
