 ## [Unreleased]
 
+## [1.37.2] - 2026-10-23
+
+### Added
+
+- **Payment status checks** for when a provider's notification never arrives. Payments → Reconcile has a new "Waiting for payment" list: online checkouts from the last 14 days with no payment yet, each with "Check status" (and "Check all"). For PayFast it looks the payment up in PayFast's transaction history and, if PayFast received it, records it exactly as the notification would have (same amount check, tickets and emails). A background job does this every 15 minutes for checkouts between 10 minutes and 3 days old (`payment-status`, switch off with `PAYMENT_STATUS_JOB_ENABLED=false`). Yoco's API has no way to look a payment up, so Yoco checkouts show "can't check" — find them in the Yoco portal and record them with Reconcile, as before.
+- **Test connection** on the PayFast settings card: checks the saved merchant ID and passphrase with PayFast.
+
+## [1.37.1] - 2026-10-23
+
+### Changed
+
+- **No "Pay online" when it can't be used.** When no payment provider is switched on, or the amount is under the R15 minimum, the registration success page, My Events ("Make payment" and "Make donation"), the donate page, "Sponsor a spot", the donation box on the register form and the supervisor Payment Link tab no longer offer online payment. Where it helps, they say why and to pay at the event instead.
+- Roadmap: SnapScan and Zapper are dropped (Yoco and PayFast are enough); later releases move up two versions — POPIA toolkit is next as 1.38.0.
+
+## [1.37.0] - 2026-10-23
+
+### Added
+
+- **PayFast.** A second online payment provider (card, instant EFT and more). Switch it on in Site settings → Payments, then enter the merchant ID, merchant key and salt passphrase from your PayFast (or Sandbox) dashboard and choose Sandbox or Live. Payments are confirmed by PayFast's notification (ITN) at `/api/webhooks/payfast`, which is checked the way PayFast requires: the signature, that it came from PayFast, that PayFast confirms it, and that the amount matches the checkout. PayFast starts switched off.
+- **Choosing how to pay.** When more than one provider is on, payers choose on a new "Pay online" page (`/pay/…`). Payment links in emails, WhatsApp and invoices go there too, so they work for every provider.
+- Payer-facing wording no longer says Yoco: "Pay online" after registering, a neutral redirect message, and the Terms and Privacy pages name both providers (Yoco or PayFast), including that PayFast may receive your name and email to fill in its payment page.
+- A payment of a different amount from the checkout (e.g. changed along the way) isn't recorded automatically: it waits in "Unreconciled Online Payments" with a note explaining why.
+
+## [1.36.0] - 2026-10-23
+
+### Added
+
+- **Site settings → Payments** (replaces the Yoco tab): turn each online payment provider on or off and set their order. The first one enabled and set up is used by default. Yoco's keys and webhook settings are on the same tab. Yoco is the only provider for now; PayFast, SnapScan and Zapper follow in the next releases. If no provider is on and set up, online payments are off and people pay at the door.
+
+### Changed
+
+- Online payments go through one payment provider layer (`backend/src/payments`). Yoco works exactly as before: the same checkout, the same webhook URL (`/api/webhooks/yoco`) and the same reconciliation.
+- **Online payments must be at least R15**, for every kind of online payment (balance, part-payment, donation, sponsorship). A smaller balance is paid at the door.
+- Payments record which provider took them (`provider`, e.g. "yoco"); existing online payments are marked as Yoco. The payment method (card, Apple Pay…) is unchanged, so cashups and reports add up as before. Provider fees are still never deducted or added — they're handled at cashup.
+- Yoco transactions are now "provider transactions" (`/api/provider-transactions`, with `/api/yoco-transactions` still working). The Payments page's reconcile list is called "Unreconciled Online Payments" and shows the provider. The database table is renamed in place, so stored transactions are kept.
+- The checkout endpoint is now `POST /api/payments/checkout` (with an optional `provider`); `/api/payments/yoco-checkout` still works.
+
+## [1.35.1] - 2026-10-23
+
+### Added
+
+- **Waitlist per session.** On pick-sessions events, a full session shows "Join waitlist" in the session list, and the waitlist works per session: when a place in that session frees up, the next person waiting for it gets the offer. Offers never run past the session's start, and nobody is offered a session that has started or was cancelled. The claim link ticks the session for them. My Events, the claim page and the supervisor Waitlist page show which session an entry is for.
+- **"All sessions" tickets on pick-sessions events let people choose their sessions.** When an event's "How people book" is "Pick sessions", every ticket now shows the session list. A ticket set to "All sessions" is still one ticket at one price, whatever is ticked. The ticket then only scans on the ticked sessions (online and offline), and the attendance register, certificates, session reminders and session capacity follow them. Tickets and the ticket email list the ticked dates. A ticket set to "Pick sessions" is still charged per session. Events booked as "The whole course" show no session list. Bookings made before this cover every session, as before.
+- **Session picker at the door.** The At the door "Select items" pop-up now has the session picker for per-session tickets, so walk-ins can be booked straight in. For a new attendee, a place in today's session is selected by default when there's room.
+
+### Changed
+
+- Per-session tickets show their list of sessions straight away (on the registration page, Manual registration, At the door and the self-service kiosk). Before, the list only appeared after pressing "+", so it wasn't obvious you could choose sessions. Ticking a session sets the quantity to 1.
+
+### Fixed
+
+- Per-session stock limits on pick-sessions tickets weren't being enforced, and the public event page lost all stock information on events with such a ticket.
+- The offline-scanning service worker served the app's script files from its cache first, for good. On a development server, where those files keep their names when they change, a browser that had opened the scanner kept running old code on every page, even after a hard reload. It now fetches them from the network and uses the cache only when offline. Its cache is renamed, so old copies are cleared.
+- At the door, editing a registration that has per-session tickets could no longer be saved ("below the quantity already issued").
+- Whole-course tickets: the waitlist now also counts room in sessions that have a capacity, so it no longer says "places available" when a session is full. Places held for waitlist offers now count towards session capacity.
+
+## [1.35.0] - 2026-10-23
+
+### Added
+
+- **Pick sessions.** A multi-day event can let people choose which sessions to come to — day passes for a conference, or a weekly drop-in class. In the event wizard choose "How people book: Pick sessions", then in Items & Pricing set a ticket to "Pick sessions (price per session)". People tick the sessions they want when they register; each session is its own line and its own ticket, at the per-session price (early-bird and staff prices apply per session; late-joiner pricing doesn't). A session can be booked until it starts (staff can book until it ends). Whole-course tickets can still be sold alongside, and stop selling when the course starts.
+- **Session capacity**: in pick-sessions events each session can have a capacity, covering picked places plus whole-course tickets. Full sessions can't be ticked. A per-session ticket's stock limit is places per session.
+- Picked-session tickets only scan on their own session ("This ticket is for Class 2 (2026-11-11)…"), on and offline. The attendance register shows one row per person with a dash for sessions they didn't book, and completion and certificates count the sessions they booked. Session reminders go only to the people booked on that session. Tickets, printouts and the ticket email show the session's date.
+- The session picker is on the public registration page, Manual registration and the self-service kiosk.
+- The roadmap to 2.0 and a handover note are now in the repo: `docs/ROADMAP-v2.md`, `docs/HANDOVER.md` (plus the previous round's spec, `docs/FEATURES-ROUND-1.md`).
+
+### Changed
+
+- Per-session tickets can't be changed from My Events' "edit booking" (book more sessions by registering again); they still count towards the total. At the door, per-session tickets are booked from Manual registration (the page says so).
+
+## [1.34.0] - 2026-10-22
+
+### Added
+
+- **Background jobs page** (Admin → Site Settings → Background jobs): every scheduled job with its schedule, next run and last 10 runs (start, finish, result or error), and a "Run now" button (recorded in the audit log).
+- **End-to-end tests** with Playwright (`npm run test:e2e`): they start their own backend and frontend against a separate, freshly seeded database and cover the public pages, free and paid registration through payment, ticket, check-in and cashup, multi-day check-in with the attendance register and certificates, creating a multi-session event in the wizard, the self-service kiosk, and the jobs page.
+- **CI workflow** (`.gitea/workflows/ci.yml`): backend tests, frontend lint, typecheck and build, and the end-to-end tests on every push and pull request. It runs once a Gitea Actions runner is registered.
+- **Deploy script** (`scripts/deploy.sh <tag>`): backs up the database, checks out the tag, installs, migrates, builds and reloads PM2, going back to the previous version if a step fails before the reload. CI runs it over SSH for `v*` tags once the `DEPLOY_*` secrets are set.
+
+### Changed
+
+- Timed background jobs (daily summary, waitlist, feedback, session reminders and certificates, consent, analytics rollup, backup, temp cleanup) now run on a job queue in Postgres (pg-boss) instead of in-process timers. Each runs once per schedule even with more than one server process, failed runs are retried, and a slow run never overlaps the next. Schedules are cron, in `APP_TIMEZONE` (Africa/Johannesburg by default) rather than the server's clock; change one with `JOB_SCHEDULE_<NAME>`, or turn all jobs off with `JOBS_ENABLED=false`. The existing `*_ENABLED` flags still work; the old `*_JOB_INTERVAL_MS` settings are replaced by the schedules. If the queue can't start, the jobs run on timers as before.
+- The server lets a running job finish before it stops or restarts.
+
+### Fixed
+
+- At the door, the Check-In tab counted every past session's check-in on a multi-day ticket, so from the second session the ticket showed as fully used. It now counts only today's session.
+
+## [1.33.0] - 2026-10-22
+
+### Added
+
+- **Multi-day events.** An event can run over several sessions, e.g. every Wednesday 18:30–20:30 for 5 weeks. In the event wizard choose "Multiple sessions", create the dates from a repeat pattern (daily or weekly, every N, on chosen weekdays, for a number of sessions or until a date), then edit any session's label, times or location, add one-off dates, or cancel a session (kept for history). People register and pay once and get one ticket for every session.
+- The event page shows the schedule (past sessions greyed out, the next one highlighted, cancelled ones struck through). Event cards show "5 sessions · Wed 4 Nov – Wed 2 Dec", and multi-day events stay listed until their last session, sorted by their next one. Calendar files have one entry per session. Ticket PDFs, printed tickets and the ticket email give the session range.
+- **Late joining**: a multi-day event closes registration when its first session starts, unless late joining is on (until session N, set per event). Late joiners pay full price, a pro-rata price for the sessions still to come (rounded to the nearest R10, at least R10), or a fixed late price — main tickets only, and never more than the normal price. The event and registration pages say when the late price applies.
+- **Per-session check-in**: a multi-day ticket is checked in once per session. The scanner uses today's session (staff can pick another), shows the session on the confirm screen, and says "Already checked in for Week 3 at 18:42" on a second scan. Each event chooses whether check-in is open the whole day of a session (the default) or only from 2 hours before it until it ends. Offline mode downloads the list for today's session, and synced scans count for the session at their scan time.
+- **Session reminders**: optional per event — 1 hour, 3 hours and/or 1 day before each session, by email and/or WhatsApp (each person's notification preference still applies). Off by default.
+- **Attendance register** (Dashboard → Attendance): attendees × sessions with ticks, totals per session, completion, search and filters (completed, not completed, missed the last two sessions), and Excel/PDF export. Supervisors can tick someone present or absent, recorded in the audit log. Also works for single-date events (one "Checked in" column).
+- **Completion certificates**: optional per event, in the wizard's new Attendance step. Four designs (Classic, Modern, Church, Kids) with the site logo and colour, your title and wording ({name}, {event}, {sessionsAttended}, {totalSessions}, {endDate}), an optional signature name, role and image, and who qualifies (every session, at least N sessions, or at least N%). "Preview certificate" shows a sample. Certificates are issued automatically when the event ends (and can be sent automatically), or from the attendance register: issue now, issue to one person anyway, send, download all as one PDF, or revoke. People download theirs under My Certificates on My Events. Each has a code and QR code that anyone can check on the public page `/certificates/verify/<code>`, which shows only the name, event and dates.
+- Saving an event where sessions moved or were cancelled offers a "Message attendees" link, since registrants aren't told automatically.
+- A background job every 5 minutes sends due session reminders and issues certificates (`SESSION_JOBS_ENABLED=false` to turn it off). The church's timezone for "today" defaults to Africa/Johannesburg (`APP_TIMEZONE` to change).
+
+### Changed
+
+- The event wizard has a ninth step, Attendance, for late joining, check-in window, session reminders and certificates.
+
+## [1.32.0] - 2026-10-22
+
+### Added
+
+- Event cards on the home page and events list show a diagonal "Early bird" ribbon in the top-right corner while the event has an early-bird tier running (deadline not passed and places left on that tier). It isn't shown when the event is sold out, registration is closed or not open yet, or the event is contact-only.
+
+## [1.31.1] - 2026-10-22
+
+### Added
+
+- Settings → Organisation has a "Google Search Console verification" field. Paste the HTML tag from Search Console and the site outputs it on every page, so each deployment can verify its own domain without uploading a file.
+
+## [1.31.0] - 2026-10-22
+
+### Added
+
+- The registration funnel's traffic source works without tagged links: visits from Facebook, Instagram, Google, X, LinkedIn and other sites are recognised from where the visitor came from (and Facebook's/Google's click ids). Links without a tag used to count as "direct". WhatsApp still only shows from tagged links (`?utm_source=whatsapp`), since it doesn't pass that on.
+- The event page's Share button shares the link tagged `?utm_source=share`, and Save QR encodes it tagged `?utm_source=qr`, so those visits show separately.
+- Event pages tell search engines about the event in Google's event format (schema.org `Event`): name, dates, venue, picture, organiser, ticket prices in Rand and whether it's sold out. Google can then show events with their date, venue and ticket link in search results and in its event listings. Contact-only events are listed without tickets.
+
+### Changed
+
+- Event pages, the events list and the home page tell search engines their one official address, so `?utm_source=…`, `?src=…` and alias links all count towards the same page in search rankings. Shared event links also carry the event's address.
+
+## [1.30.1] - 2026-10-22
+
+### Changed
+
+- All tickets now share the design of the tickets printed from the user dashboard: rounded white cards with a light border and soft shadow, the date beside the event name, and the QR code in the middle. This covers the PDF sent by email and WhatsApp (now 6 per page, so the QR codes are bigger) and printing from Event Tickets (staff) and At the door (supervisor). Printed names are now escaped, so a name with `<` or `&` prints correctly.
+
+## [1.30.0] - 2026-10-22
+
+### Added
+
+- The register form asks for an optional **Donation amount** under the ticket options. Pick a suggested amount (worked out from the ticket total), enter a custom amount (min R15), or choose None. The donation shows in the total and is paid in the same Yoco checkout as the tickets. It's recorded as a separate donation to the event, so it never counts towards the registration's balance.
+
+### Fixed
+
+- Event pages with a waitlist crashed with "Attempted to call soldOutLines() from the server". The sold-out helper now lives in `lib/waitlist.ts` so the server page can call it.
+
+## [1.29.1] - 2026-10-21
+
+### Changed
+
+- The Coupon codes page matches the Bundle deals page and works on phones. Codes show as cards with the discount, events, uses, restrictions, dates and limits. On phones, the edit form and the list of uses open full-width from the bottom, and the discount type is picked from three buttons.
+- The coupons list hides codes that are off, expired or used up unless you tick "Show codes that are off, expired or used up". Search also matches event names.
+- When creating or editing a code, the Events list shows upcoming events only, soonest first, with a search box and a "Show past events" option. Past events already on the code stay listed so they can be unticked.
+
+## [1.29.0] - 2026-10-21
+
+Run `npm run prisma:deploy` in the backend when deploying. This release adds a migration.
+
+### Added
+
+- Bundle deals now come in four types, chosen when you create one:
+  - **Exact set**: these tickets in these numbers for one price, e.g. 2 adults + 3 kids for R220. This is how bundles worked before.
+  - **Pick any**: any mix of the qualifying tickets for a set price, e.g. any 4 of Adult or Child for R250, so 2 + 2 and 4 + 0 both count.
+  - **Buy X get Y free**: in every set of qualifying tickets the cheapest are free, e.g. buy 3, get 1 free.
+  - **Group discount**: from a group size up, every qualifying ticket costs less (a price per ticket or a percentage off), e.g. 10+ tickets: R70 each. It applies once, to the whole group, and never makes a ticket dearer.
+- The deals list and the "Complete bundle" cards on the register form, at the door, manual registration and the kiosk describe each type in one line, e.g. "Any 4 of Adult, Child for R250". For a group discount the button reads "Complete group" and adds the tickets still needed.
+- `npm run set-demo`: Family Fun Day also has a pick-any deal, "Lunch for four" (any 4 lunch packs for R220).
+
+## [1.28.3] - 2026-10-21
+
+### Fixed
+
+- Bundle deals edit form: each ticket row's quantity box filled the whole row, which pushed the ticket picker off the side and added a sideways scrollbar. The quantity box is narrow again, with the ticket picker beside it.
+
+## [1.28.2] - 2026-10-21
+
+### Changed
+
+- The Bundle deals page has a new layout that works on phones. It shows upcoming events only, soonest first, with a "Show past events" option. Bundles show as cards with their tickets, price, saving, uses and dates. On a phone, the edit form opens full-width from the bottom, and its price section shows the standard price, the bundle price and the saving side by side.
+
+## [1.28.1] - 2026-10-21
+
+### Added
+
+- At the door, manual registration and the self-service kiosk now list the event's bundle deals and show the same bundle cards as the register form: once a ticket from a bundle is picked, **Complete bundle** tops up the ticket numbers, and **+** adds another full set.
+
+### Fixed
+
+- At the door now has the same "← Back to dashboard" link as the other dashboard pages.
+- At the door's "less than already paid" warning shows the total after bundle deals.
+
+## [1.28.0] - 2026-10-21
+
+Run `npm run prisma:deploy` in the backend when deploying. This release adds a migration.
+
+### Added
+
+- **Bundle deals**: sell a set of tickets together for one price, e.g. 5 Adult + 3 Child for R500 instead of R550. Supervisors set them up per event under Dashboard → **Bundle deals**: the tickets and quantities (one variant or any variant), the price, optional dates, and on/off.
+- Bundles apply automatically, with no code, as many times as a registration's tickets allow; leftover tickets are charged as usual. A bundle only applies when it's cheaper than the tickets at the prices actually charged, early-bird and staff prices included. When several compete, the one that saves the most is used first. This works for online registration, manual registration, at the door and on the kiosk.
+- The event page and the register form list the event's deals, and every basket shows the saving live. On the register form, once a ticket from a bundle is picked, the bundle appears with what's missing and a **Complete bundle** button that tops up the ticket numbers. Once it's complete, **+** adds another full set. Invoices, receipts, emails, WhatsApp messages and the Yoco payment page show it as its own line, e.g. "Bundle: Family deal ×2".
+- The Discounts report lists bundle deals next to coupon codes. Each bundle shows how often it's been used and the total saving given.
+- `npm run set-demo`: Family Fun Day sells a **Family deal** bundle (2 adults + 3 kids for R220) in place of the old Family pass ticket.
+
+### Changed
+
+- Coupon codes now work out after bundle deals, on what's left. Registration.discountTotal now holds bundle and coupon discounts together, with the bundle part in the new `bundleDiscount`.
+- Removing a code from a registration keeps its bundle deal. When an early-bird tier expires before payment and prices change, bundle deals are worked out again and coupon amounts are kept.
+- Registrations keep a bundle they already have, even after it's turned off or its dates pass. Deleting a bundle that has been used turns it off instead.
+
+## [1.27.1] - 2026-10-21
+
+### Added
+
+- `npm run set-demo` also stages ten completed events from the past year, with door sales recorded by staff, staff cash counts, check-ins, refunds, donations and post-event feedback. Their cashups go through every path: a quick close; full closes with card fees, a cash deposit fee, a written-off shortfall, cash kept on hand and an unaccounted amount; a close, reopen and re-close; pending EFT money that was later received and some still outstanding; and one event left open with the cash counted, ready for a live cashup. Funnel stats older than 90 days are stored as daily totals, the way the app rolls them up. See `backend/DEMO_DATA.md`.
+
+## [1.27.0] - 2026-10-21
+
+Run `npm run prisma:deploy` in the backend when deploying. This release adds a migration.
+
+### Added
+
+- Cashups now record where each payment method's money ended up. For cash, card, EFT and other, the expected takings are split into what's **in the bank**, **cash on hand**, and **pending** (on the card machine or Yoco report, or with a proof of payment), with a reference for the pending amount. Card fees, bank charges, cash shortfalls and other losses are **written off** with a reason. Each method shows what's still **unaccounted**. Closing with an unaccounted amount is allowed after a warning, and the amount comes off profit, as variance did before.
+- When staff have counted the cash, cash on hand is worked out for you: the count, less what reached the bank and any deposit fee written off as a bank charge.
+- Pending money on a closed event can be marked **received** or **written off** later from the cashup screen, without reopening the event. Each one is logged with who did it and when.
+- Reopening an event starts the next cashup from the last one, with any pending money settled since folded in.
+- Write-offs show as **Bank & card charges** on the cashup screen and in the Cashup, Finance and Profit reports. The Cashup report has new In bank, On hand, Pending, Written off and Unaccounted columns.
+
+### Changed
+
+- Net profit now subtracts write-offs as their own line instead of showing card fees and bank charges as missing income. The net figure is the same.
+- Every dashboard page uses the same back link: the small "← Back to dashboard" link above the page title, as on the Waitlist page. The grey Back buttons are gone. Site settings, profile, donate and manual registration, which had no way back, now have one too.
+
+## [1.26.1] - 2026-10-21
+
+### Added
+
+- `npm run set-demo` in the backend replaces the database contents with demo data for showing the platform to other churches. It keeps the site settings and the admin account, and stages six upcoming events with registrations, payments, tickets, a waitlist, camp cabins, coupons, costs and funnel stats. See `backend/DEMO_DATA.md`.
+
+## [1.26.0] - 2026-10-21
+
+### Changed
+
+- Upgraded Prisma from 5.22 to 7.10. Prisma 7 connects through the `@prisma/adapter-pg` driver adapter (node-postgres) instead of the Rust query engine. The database URL moved from `schema.prisma` to the new `backend/prisma.config.js`, which loads `backend/.env` itself. All Prisma clients are now created in `src/config/db.js`, and the server shares one client instead of opening two connection pools. No schema or migration changes.
+- Prisma 7 checks TLS certificates on database connections. A `DATABASE_URL` that uses SSL with a self-signed or otherwise invalid certificate now fails to connect where Prisma 5 accepted it.
+- `npm run dev` in the backend now uses Node's built-in `node --watch` instead of `nodemon`.
+- The frontend now passes ESLint with no errors or warnings, down from 1,137, and `next build` runs ESLint again. It was skipped before (`eslint.ignoreDuringBuilds`), which is how the issues built up.
+  - API data is now typed. `src/types` describes the records the backend returns, modelled on the Prisma schema, and `apiFetch` returns `unknown` unless the caller names a type, so untyped responses no longer pass silently.
+  - Effects list everything they depend on. Data loaders are wrapped in `useCallback`, so a page reloads when its inputs change instead of showing stale data.
+  - The pricing helpers that were copied into several pages now live in `src/lib/pricing.ts`.
+
+### Fixed
+
+- Internal links on the home page, the 404 page and "Forgot your password?" now navigate client-side instead of reloading the whole page.
+- Changing the page size on Admin → Users fetched the list twice; it now fetches once.
+- At the door, the refund history now shows a refund's reason. The page was reading a field that doesn't exist, so the reason never appeared.
+- In the Master Orders report, a ticket option named like one of the fixed columns (e.g. "name") could overwrite that column's value.
+- Removed code that could never run: an unreachable "Pay with Yoco" button on the registration form, an unused attendee-forms block on the registration success page, unused export helpers in Reports, and fonts that were downloaded but never applied.
+
+### Security
+
+- Backend `npm audit` now reports 0 vulnerabilities:
+  - Patched `follow-redirects` (pulled in by `axios`) to 1.16.1, which fixes leaking credential headers on cross-origin redirects.
+  - Removed `nodemon`, the only backend package that pulled in `braces`.
+  - Jest's coverage loader now uses `js-yaml` 4, which drops the `sprintf-js` advisory.
+- Frontend: overrode `postcss-selector-parser` to 7.1.7, used by the Tailwind 3 build. The generated CSS is byte-identical. The remaining frontend findings (7 high) are all the same `braces` advisory (GHSA-vfj7-8cjw-p6xm). It has no patched release, comes in only through build and lint tools (Tailwind 3 and `eslint-config-next`), and only ever handles glob patterns from our own config, never user input.
+
+## [1.25.1] - 2026-10-20
+
+### Fixed
+
+- On mobile, the cookie consent banner now sits above the bottom navigation bar instead of being hidden behind it.
+- The floating help button moves up above the cookie consent banner while it is showing, so the banner no longer covers it.
+

+## Multi-day events & attendance
+
+An event with `scheduleType: "sessions"` runs on several dates (e.g. every Wednesday for
+5 weeks). People register and pay once and get one ticket; check-in is per session.
+`startDate`/`endDate` always follow the first and last active session.
+
+Create/update fields (`POST`/`PUT /api/events`):
+
+| Field | Notes |
+|-------|-------|
+| `scheduleType` | `single` (default) or `sessions`. Switching back to `single` is refused once there are session check-ins |
+| `attendanceMode` | `whole` (default) or `pick` — people choose sessions. Not allowed with `requiresParentalConsent` |
+| `sessions` | `[{ id?, label?, startsAt, endsAt, location?, cancelled?, capacity? }]` — the full list. Rows left out are deleted (refused when they have check-ins — send `cancelled: true` instead). The event and its sessions save together, so a refused change saves nothing |
+| `lateJoinEnabled`, `lateJoinUntilSessionIndex` | Registration stays open until that session (index into the sent list, sorted by start) starts; otherwise it closes when the first session starts |
+| `latePricing`, `lateFixedPrice` | `full`, `prorata` (price × sessions left ÷ sessions, nearest R10, at least R10) or `fixed` (only ever lowers the price). Main tickets only |
+| `checkInWindow` | `whole_day` (default — any time on the session's date, in `APP_TIMEZONE`, default Africa/Johannesburg) or `session_only` (2 h before start until the end) |
+| `sessionReminders` | `null` (off) or `{ offsets: [60 \| 180 \| 1440], channels: ["email", "whatsapp"] }` |
+| `certificatesEnabled`, `certificateConfig` | `{ template: classic \| modern \| church \| kids, title, body ({name} {event} {sessionsAttended} {totalSessions} {endDate}), signatureName, signatureRole, signatureImage, rule: { type: all \| count \| percent, value }, sendOnIssue }` |
+
+Event options take `sessionMode: "all" | "pick"` (`POST /api/events/:id/options`, `PUT /api/events/options/:id`).
+In a pick-mode event, a `pick` option is bought per session: registration lines send
+`sessionIds: [...]` (`POST /api/registrations`, `/manual`, coupon/bundle quotes), and each
+session becomes its own registration line (`RegistrationOption.sessionId`) and ticket.
+Capacity counts picked places plus whole-course main tickets; a pick option's
+`stockLimit` is per session. `PUT /api/registrations/:id/options` refuses pick options and
+leaves picked lines untouched. An `all` option in a pick-mode event may also send
+`sessionIds`: it stays one line and one ticket at one price, with the sessions kept in
+`RegistrationOption.sessionIds` (empty = every session). That ticket only scans on those
+sessions, and capacity, reminders, the register and certificates follow them; adding more
+of the same ticket to a registration merges the sessions. Pick-mode events stay open until the last session starts
+(`wholeCourseClosesAt` gives when whole-course tickets stop). Single-event responses add
+`booked` and `placesLeft` per session and `sessionAvailability` per pick option.
+
+Responses for events include `sessions[]` (with `cancelled` and `hasCheckIns`),
+`registrationClosesAt`, `nextSession` and `lateJoin: { active, mode, sessionsLeft, totalSessions, fixedPrice }`.
+`PUT` also returns `sessionChanges: { added, moved, cancelled, restored, removed }`.
+
+Scanning: `GET /api/tickets/scan-preview/:qr?sessionId=` and `POST /api/tickets/scan/:qr`
+(`{ sessionId? }`) default to today's session and return `session` plus `remaining` for it;
+`sessionError` / 400 `NO_SESSION` when no session is open for check-in. Offline snapshots
+are for the session running when downloaded; synced scans count for the session at their scan time.

+# Demo data
+
+`npm run set-demo` replaces everything in the database with a realistic set of demo data,
+for showing the platform to other churches. It stages six upcoming events with
+registrations, payments, tickets and people, and ten completed events from the past year
+with door sales, check-ins, feedback and cashups. That way every dashboard, report,
+check-in and cashup screen has something to show.
+
+> **This deletes real data.** Run it only against a database you're happy to wipe, such
+> as a dedicated demo deployment. It is not something to run on a live church site.
+
+---
+
+## Running it
+
+```bash
+cd backend
+npm run set-demo            # shows the database it will wipe and asks you to type "demo"
+npm run set-demo -- --yes   # no prompt (for scripts)
+```
+
+The script uses `DATABASE_URL` from `backend/.env`. To point it at another database
+for one run, set it in the environment first. A value already in the environment wins
+over `.env`:
+
+```bash
+DATABASE_URL="postgresql://user:pass@host:5432/hope_demo" npm run set-demo
+```
+
+It takes about five seconds and is safe to re-run as often as you like. Each run wipes the
+previous demo and creates it again.
+
+### Before you run it
+
+- The admin account must already exist. By default that's `joshua@crosscode.co.za`.
+  To keep a different account, set `DEMO_ADMIN_EMAIL`:
+  ```bash
+  DEMO_ADMIN_EMAIL="admin@example.org" npm run set-demo
+  ```
+  If the account isn't found, the script stops before changing anything.
+- Migrations must be up to date (`npm run prisma:deploy`).
+
+---
+
+## What it keeps and what it clears
+
+| Kept | Cleared |
+|---|---|
+| Site settings (`AppSetting`): org name, branding, SMTP, Yoco, WhatsApp, legal pages | Every event, with its options, variants, early-bird tiers, sections, forms, costs and cash-ups |
+| The admin account, including its login history, trusted devices and 2FA | Every other user |
+| Migration history | Registrations, payments, tickets, scans, coupons, waitlists, consents, cabins, feedback, analytics, audit log |
+| Uploaded files on disk (`public/uploads`) | Queued scheduled emails/WhatsApps (`data/scheduled-emails.json`) |
+
+The wipe and the new data are written in one database transaction. If that fails,
+nothing changes. The past events' cashups run straight afterwards, through the same
+code as the cashup screen. If one of those fails, re-run the script.
+
+---
+
+## What it creates
+
+### Upcoming events
+
+All dates are worked out from the day you run it, so these events are always upcoming.
+Registrations are spread over the past month, as if sign-ups have been coming in.
+The data is generated from a fixed seed, so every run looks the same.
+
+| When (from today) | Event | Shows off |
+|---|---|---|
+| ~1½ weeks, Sat 07:30 | **Men's Breakfast: Built to Last** | **Sold out** (60 places), 5 people on the **waitlist**, card / cash / EFT payments recorded by staff, 2 cancelled registrations |
+| ~2½ weeks, Sat 10:00 | **Family Fun Day** | Adult and child tickets with a **bundle deal** (Family deal: 2 adults + 3 kids for R220 instead of R280, used by about a third of registrations) and a **pick-any** deal (Lunch for four: any 4 lunch packs for R220), a non-ticket **add-on** (lunch pack), a fixed-amount **coupon** (`FUNDAY20`), entry and food-stall check-in sections |
+| ~5 weeks, Fri–Sat | **Rooted Women's Conference** | Two **early-bird tiers** (one already expired, one still open) plus a Saturday-only ticket, T-shirt **variants** (S–XXL), a **required sign-up form** (dietary needs, workshop choice, prayer requests), a 20% **group coupon** (`ROOTED20`) used by 4 registrations |
+| ~7 weeks, Mon–Thu | **Ignite Summer Camp** | **Named attendees** (campers aged 12–17), signed **parental consent**, gender collected, **deposits and part-payments**, campers placed in boys' and girls' **cabins** with staff leaders, **sponsor-a-spot** donations towards a 10-spot goal |
+| ~8 weeks, Sun 19:00 | **Carols by Candlelight** | A **free event** with group tickets (1–6 people), plus general **donations** |
+| ~14 weeks, Fri–Sun | **Marriage Enrichment Weekend** | Room-type **variants with limited stock**, early-bird prices per room type, a per-person spa add-on, R1 000 EFT deposits |
+
+Each event also gets:
+
+- A cover photo (from Unsplash, which `next.config` already allows) and a contact person.
+- **Costs**, both once-off and per item, so the profit view and cash-up have figures.
+- About 30 days of **funnel analytics** (views → started → submitted → paid) by source
+  (WhatsApp, Facebook, Instagram, email, direct) and device.
+
+Paid registrations have tickets with QR codes, the same way the app issues them once
+payment is complete. Part-paid and pending ones don't have tickets yet.
+
+### Past events
+
+Ten completed events spread over the past year, for showing cashups and the historical
+reports. Each one has:
+
+- Online sales in the five weeks before the event, with a few unpaid no-shows.
+- **Door sales** on the day, recorded by the staff team (cash and card machine).
+- **Check-ins**: about 90% of tickets scanned, with the odd group arriving short.
+- **Staff cash counts** with note and coin denominations.
+
+Some events also have refunds, donations and post-event feedback.
+
+The cashups cover every path through the cashup screen:
+
+| When | Event | Cashup to demo |
+|---|---|---|
+| ~11 months ago | **Church Family Picnic** | **Quick closed** (no settlement) |
+| 24 Dec | **Christmas Eve Candlelight Service** | Free event with card and cash **donations**. Card settled net of **Yoco fees**, collection banked |
+| Easter Sunday | **Easter Sunrise Service & Breakfast** | Cash banked less a **cash deposit fee** (bank charge), card fees, a **refund** |
+| Mother's Day | **Mother's Day Brunch** | **Closed with R50 cash short → reopened → recounted → closed again.** The history shows all three steps |
+| ~3½ months ago | **Youth Winter Camp** | Deposits and balances. **EFT pending** (POPs) at close, later **marked received** without reopening |
+| ~2½ months ago | **Men's Golf Day** | Card-heavy, card fees written off, a refund |
+| ~2 months ago | **Kids Holiday Club** | Cash-heavy door sales. **R20 cash shortfall written off**, **R500 kept on hand** as float |
+| ~6 weeks ago | **Women's High Tea** | Closed with **R30 unaccounted**, shown in red |
+| ~4 weeks ago | **Missions Fundraiser Dinner** | **R2 600 EFT still pending** (POP received, not cleared). Shows "Mark received" / "Write off" |
+| ~10 days ago | **Worship Night** | **Still open, with the cash already counted.** Use it to do a cashup live in the demo |
+
+Easter, the Youth Camp, the Holiday Club and the High Tea have **feedback forms** with
+ratings and comments. Funnel stats older than 90 days are stored as daily totals, the
+way the app rolls them up overnight, so the funnel report covers the whole year.
+
+### Totals
+
+A typical run gives roughly:
+
+| | |
+|---|---|
+| Users | 130 (plus the admin) |
+| Registrations | ~700 (paid, part-paid, pending, cancelled and refunded) |
+| Payments | ~640, including donations, sponsorships and refunds |
+| Tickets | ~780, with ~490 check-ins |

+## Logging in
+
+Every demo account uses the password **`Demo@1234`**.
+
+| Role | Email | Good for showing |
+|---|---|---|
+| Supervisor | `lerato.khumalo@example.com` | Event setup, reports, coupons, viewing cashups |
+| Staff | `sipho.dlamini@example.com` | At-the-door payments and check-in scanning |
+| Staff | `anri.botha@example.com` | |
+| Staff | `daniel.pillay@example.com` | |
+
+Closing, reopening and settling pending money in a cashup are admin-only, so do the
+live Worship Night cashup as your own admin account.
+
+The other 126 people are ordinary members (role `user`), with emails like
+`thandi.mokoena@example.com`. Log in as one of them to show the member view: their
+registrations, tickets and payments. Any registrant's email from an event's attendee
+list works.
+
+Your own admin account keeps its existing password.
+
+---
+
+## Safety
+
+- **Nothing is sent.** The script writes straight to the database and never calls the
+  email, WhatsApp or Yoco code.
+- **Nothing can reach a real person later.** Demo people use `@example.com` addresses
+  (a reserved domain that can't receive mail) and have **no phone numbers**, so
+  reminders or broadcasts sent during a demo go nowhere. All parental consents are
+  already signed, so no consent reminders go out.
+- Card payments have made-up Yoco ids (`demo_…`). They don't exist in Yoco, so leave
+  the demo site's Yoco settings in test mode or empty.
+
+---
+
+## Customising
+
+Everything lives in [`scripts/set-demo.js`](scripts/set-demo.js). There is one
+`build…()` function per event (`buildMensBreakfast`, `buildYouthCamp`, …), and
+`main()` decides which ones run. To change an event's name, prices, ticket types or
+number of registrations, edit its function. To add an event, write a new `build…()`
+and add it to the list in `main()`. `addBundle(event, { name, price }, [[option, quantity], …])`
+adds a bundle deal. Registrations added after it get the deal automatically, worked out
+the same way as the app does it.
+
+The past events are in `buildPastEvents()`, one spec each: dates, ticket types, costs,
+how many people bought online and at the door, and a `cashup` that says how it was
+closed. Supported closes:
+- `'quick'`
+- `'full'`, with `lines` saying where the money ended up
+- `'reclose'`
+- `'none'`, which leaves the event open
+
+A full close can add `later` to settle pending money after closing. The helpers
+`cardLine`, `eftLine` and `cashLine` build the usual settlements: card net of Yoco fees,
+EFT with an optional pending POP, and cash banked with an optional float, deposit fee or
+shortfall.

+ *   one backend process is running (PM2 cluster, two servers on one database).
+ * - Every run is recorded (state, start/end, result or error), shown on the admin
+ *   Background jobs page, which can also run a job straight away.
+ * - A run that fails is retried, and a slow run never overlaps the next one.
+ *
+ * Each job can be switched off with its env flag (e.g. WAITLIST_JOB_ENABLED=false), and
+ * its schedule changed with JOB_SCHEDULE_<NAME> (cron, e.g. JOB_SCHEDULE_WAITLIST="*\/5 * * * *").
+ * JOBS_ENABLED=false turns all of them off (used by the end-to-end tests).
+ * If the queue can't start (e.g. the database user can't create the pgboss schema), the
+ * same jobs run on in-process timers instead, as before.

+/**
+ * Bundle deals — tickets sold together at a better price. Four kinds:
+ * - exact: these tickets in these numbers for a set price, e.g. 5 Adult + 3 Child for R500.
+ * - mix:   any `setSize` of the qualifying tickets for a set price, e.g. any 4 for R250.
+ * - free:  any `setSize` qualifying tickets with the cheapest `freeCount` free, e.g.
+ *          buy 3 get 1 free (setSize 4, freeCount 1).
+ * - group: `setSize` or more qualifying tickets, all of them at `price` each
+ *          (groupPricing per_ticket) or `price`% off (percent).
+ *
+ * Rules:
+ * - Applied automatically: no code needed. exact, mix and free apply as many times as
+ *   the registration's items allow; leftover items are charged as usual. A group
+ *   discount applies once, to every qualifying ticket.
+ * - Best price wins: a bundle only counts when it beats what its items cost at the
+ *   prices actually charged (early-bird, staff price), so it never makes anything
+ *   dearer. A group discount never raises a ticket's price. The most expensive matching
+ *   units go into a bundle first, and when several bundles compete the one saving the
+ *   most is applied first.
+ * - A bundle item with no variant matches any variant of its option.
+ * - Coupons are worked out after bundles, on what's left: bundled units are passed on
+ *   to the coupon code at their share of the bundle price (see utils/coupons.js).
+ * - The discount is stored on Registration.bundleDiscount (and included in
+ *   discountTotal), with one RegistrationBundle row per bundle used.
+ * - A registration keeps any bundle it already has, even after the bundle is switched
+ *   off or its dates pass, so editing a registration never takes a deal away.

+ * Multi-day events — one event running on several dates ("sessions"), e.g. every

+ *
+ * Rules:
+ * - Event.startDate/endDate always mirror the first active session's start and the last
+ *   active session's end, so everything that only reads those keeps working.
+ * - A cancelled session is kept (it may have check-ins) but is hidden from the schedule
+ *   and left out of totals. A session with check-ins can't be deleted, only cancelled.
+ * - Check-in is once per session. "Whole day" accepts a scan any time on the session's
+ *   date (in the church's timezone); "session only" from 2 h before the start until the end.
+ * - Registration closes when the first session starts, or — with late joining — when
+ *   session N starts. A registration deadline, if set, still wins when it's earlier.
+ * - Late pricing applies to main tickets only, for people registering after the first
+ *   session has started: pro-rata on the sessions left (nearest R10), or a fixed price.
+ * - "Pick sessions" events (attendanceMode pick): options with sessionMode `pick` are
+ *   bought per session — one registration line (and ticket) per session, priced per
+ *   session, bookable until that session starts. `all` options cover every session and
+ *   follow the whole-course rules above. A session's capacity counts picked places plus
+ *   whole-course main tickets (and places held for waitlist offers); a pick option's stock
+ *   limit is places per session. The waitlist for a pick option is per session.
+ *   `all` options on such an event also let people tick the sessions they'll come to
+ *   (RegistrationOption.sessionIds): one line, one ticket and one price, but the ticket
+ *   scans, counts towards capacity and gets reminders for those sessions only. No

+
+## 1. Coupon codes
+
+Discount codes applied at registration. The main use case is **staff
+registering for events** at a reduced or free rate, but codes also work for
+promos, leaders, and volunteers.
+
+**Who:** Supervisors create and manage codes. Users enter them at checkout.
+Supervisors can also apply them in Manual registration, At the door and the
+kiosk.
+
+### Code settings
+
+| Setting | Options |
+|---------|---------|
+| Code | Unique text, case-insensitive (e.g. `STAFF50`) |
+| Discount type | Percentage · Fixed amount · Comp (100% free) |
+| Scope | Whole event · Specific ticket option(s) · Specific variant(s) |
+| Events | One event, several events, or all events |
+| Valid from / until | Optional date window |
+| Max total uses | Optional |
+| Max uses per user | Optional (default 1) |
+| Min quantity | Optional (e.g. 4+ tickets) |
+| Restricted to | Anyone · Specific users · Roles (e.g. Staff and above) · Email domain |
+| Stack with early-bird | Yes (apply on top of early-bird price) / No (best price wins) |
+| Active | On / off toggle |
+
+### How it works
+
+- The user enters a code on the registration page. It is validated server-side
+  and the discount shows as its own line before payment.
+- The discount is stored as a **separate discount line on the registration**,
+  with its value **locked at apply time**, the same way early-bird tranches
+  are locked. Pricing refresh never re-prices an applied coupon, even if the
+  code later expires or is disabled.
+- **Restricted codes** (by user, role or domain) need the user to be logged
+  in. Guest registration can't use them. This stops staff codes leaking in
+  group chats.
+- **Role-based staff pricing (optional):** a ticket option can also carry a
+  "Staff price" that applies automatically for Staff+ users without a code.
+
+### Edge cases
+
+- **Edit options:** percentage codes recalculate over the new item total.
+  Fixed-amount codes stay fixed. Comp codes cover only in-scope options.
+- **Cancellation / refund:** a cancelled registration releases its use count.
+- **Discount can't go below R0.** A comp code on a fully covered registration
+  marks it Paid and generates tickets.
+- **Concurrency:** check use limits inside a transaction so the last use
+  can't be claimed twice.
+
+### Plumbing
+
+- Invoices and receipts show the code and discount line.
+- **New report: Discounts.** Uses per code, total value given away, per event.
+- Finance and profit reports subtract discounts from expected revenue.
+- **Audit log:** code created, edited, disabled, and manually applied by staff.
+

+  createdAt       DateTime @default(now())
+  releasedAt      DateTime?        // set on cancellation
+}
+```
+
+---
+
+## 2. Waitlist
+
+When an event or ticket option is sold out, users can join a waitlist instead
+of hitting a dead end.
+
+**Who:** Users join. Supervisors view and manage the queue.
+
+### How it works
+
+- Sold-out options show a **"Join waitlist"** button instead of "Sold Out".
+- The user picks an option, variant and quantity. Login is required if the
+  event requires login. Otherwise a guest account is created as usual.
+- When stock frees up (a cancellation, a refund, or a supervisor raising the
+  stock limit), the **next person in line** gets an email/WhatsApp with a
+  **claim link**.
+- The claim link **reserves the stock for a set time** (default 24 h, set per
+  event). If it isn't used in time, the offer moves to the next person.
+- A claimed offer goes through normal registration and payment, with
+  early-bird and coupon rules applied as usual.
+
+### Supervisor tools
+
+- A waitlist tab per event shows position, person, option, quantity, joined
+  date and offer status.
+- Supervisors can manually offer a spot to someone, reorder the queue, or
+  remove an entry.
+- Supervisors can toggle the waitlist on or off per event.
+
+### Edge cases
+
+- Reserved-but-unclaimed stock counts as sold until the offer expires, so the
+  public site doesn't oversell.
+- If an offer is for quantity 3 and only 2 free up, offer the 2 with a note,
+  or skip to the next person who fits. This is configurable per event.
+- Users can leave the waitlist from their dashboard.
+- Add the waitlist to the Daily summary (count per event).
+
+---
+
+## 3. Group tickets
+
+One payer registers **several named attendees**, each with their own ticket
+and their own form response. For example, a parent registers three kids for
+camp.
+
+**This is optional.** The payer can still choose to receive all tickets
+themselves.
+
+### How it works
+
+- On the registration page, a toggle reads **"Registering for other people?"**
+- For each attendee: name, plus optional email/phone, plus the event form if
+  there is one.
+- **Ticket delivery choice per registration:**
+  - **Send all tickets to me** (default), so the payer gets every ticket.
+  - **Send each person their own ticket**, using their email/WhatsApp. If an
+    attendee has no contact details, their ticket falls back to the payer.
+- Tickets are **individual, named tickets** rather than a quantity ticket, so
+  each one can be checked in, transferred or allocated to a room/group
+  separately.
+- The payer stays the account owner for billing, invoices and payments.
+
+### Edge cases
+
+- Works alongside the existing quantity tickets, since an event can allow
+  either.
+- If an attendee's email/phone matches an existing account, link the ticket
+  to that account (with the same duplicate-account protection as today).
+- Attendee forms: each attendee has their own response. The payer can fill
+  them in, or each attendee can get a link to fill in their own.
+- Feeds into parental consent (one consent request per minor attendee) and
+  group/room allocation.
+
+---
+
+## 4. Offline scanning
+
+Lets the scanner keep working when venue Wi-Fi or mobile data drops.
+
+> ⚠️ **Rules: offline mode is per section, and only one device can scan a
+> section offline at a time.**
+> While offline, devices can't see each other's scans. If two devices scanned
+> the same section offline, the same ticket could be redeemed twice. Locking
+> each section to a single device removes that risk without needing conflict
+> resolution.
+
+### How it works
+
+1. **Before going offline (while online):** a staff member picks an event and
+   section and taps **"Enable offline mode"**.
+2. The server **locks that section to this device** and records the device ID
+   and the staff member. Other devices see "Offline-locked by [name] on [device]"
+   and can't scan that section, online or offline, until it's released.
+3. The device **downloads a snapshot** of every ticket valid for that section
+   (ticket ID, holder name, type, quantity remaining) into IndexedDB.
+4. **While offline:** scans validate against the local snapshot and update
+   remaining quantities locally. Every scan is queued with a timestamp.
+5. **When back online:** queued scans sync to the server automatically. Any
+   conflicts (for example, a ticket transferred or cancelled while offline)
+   show in a **sync report** for a supervisor to review.
+6. Staff tap **"Release section"** to end offline mode and unlock the section.
+
+### Rules and edge cases
+
+- One section can only be locked to one device at a time. Other sections of
+  the same event can be locked to other devices.
+- A supervisor can **force-release** a lock if a phone dies or goes missing.
+  Unsynced scans on that device are lost unless the device reconnects later,
+  in which case they sync and are flagged.
+- **Snapshot age:** show "Ticket list downloaded at 17:42". Tickets bought
+  after that time won't be on the device, and the scanner shows "Not found in
+  offline list. Check at the door desk."
+- The snapshot is stored only for the lock's duration and cleared on release.
+- Check-in confirmation messages to holders are sent after sync, not
+  instantly.
+- **Audit log:** lock, release, force-release, and sync with scan count.
+- Built as a **PWA** (service worker caches the scanner page and assets).
+
+---
+
+## 5. Parental consent (youth events)
+
+For youth events, a parent or guardian must give consent before an attendee
+under 18 can attend. The parent gets an **email and a WhatsApp** with a link
+to review and give consent.
+
+### Event setup
+
+- New event setting: **"Youth event: requires parental consent"**.
+- Supervisors write the **consent text** (indemnity, activities, photo
+  permission, transport, medical treatment authorisation) in the event wizard.
+- Optional extra sections on the consent page: **medical info** (allergies,
+  medication, conditions, medical aid), **emergency contact**, and **photo
+  consent** (Yes/No, recorded separately).
+
+### How it works
+
+1. During registration, each attendee gives their **date of birth**. If they
+   are under 18, **parent/guardian name, email and phone** are required.
+2. On registration, the parent gets an **email and a WhatsApp** (always both,
+   regardless of anyone's notification preference) with a unique, secure
+   consent link.
+3. The consent page shows the event details, attendee name and consent text.
+   The parent fills in any medical/emergency fields, **types their full name**
+   as a signature, ticks "I am the parent/legal guardian", and taps
+   **Give consent** (or **Decline**).
+4. The system records the timestamp, IP address, device, typed name and the
+   **version of the consent text** they agreed to.
+5. The registrant and the event's notify recipients get a confirmation.
+
+### Rules
+
+- **Tickets are generated but marked "Consent pending"** until consent is
+  given. Scanners show a clear warning and block check-in for that ticket
+  (supervisors can override, with an audit log entry).
+- **Reminders:** automatic reminder email/WhatsApp after 2 days, then every
+  3 days until the event, or until consent is given or declined.
+- **Declined consent:** notifies the registrant and supervisors. The
+  registration stays but can't be checked in. A supervisor handles the refund.
+- **Consent links expire** at the event's end date, and can be resent from
+  the registration detail screen.
+- If the consent text is edited after some parents have consented, they keep
+  their record of the old version. Supervisors can choose to re-request
+  consent.
+
+### Supervisor tools
+
+- **Consent status column** on registrations and At the door (Pending /
+  Given / Declined).
+- **New reports:** Consent status per event, and **Medical & emergency list**
+  (printable, for camp leaders). Access to the medical list is restricted to
+  Supervisor+ and logged.
+- Bulk "Resend consent request" to everyone still pending.
+
+### Privacy
+
+Under POPIA, processing a child's personal information needs the consent of a
+competent person (parent/guardian). Medical data is special personal
+information. Store it encrypted, restrict access, include it in the existing
+anonymise/delete flows, and delete it a set period after the event.
+
+---
+
+## 6. Sponsor a spot
+
+A public donation flow linked to a specific event, so people can fund a spot
+for someone who can't afford it (bursaries).
+
+### How it works
+
+- A new event setting: **"Allow sponsorships"**. This adds a **"Sponsor a
+  spot"** button on the event page.
+- Sponsors choose: **one full spot** (the main ticket price), **multiple
+  spots**, or **a custom amount**. Payment goes through Yoco as usual.
+- A sponsor can be anonymous, or add a name and message.
+- The money is recorded as a **donation tagged to the event**, and lands in a
+  **sponsorship pool** for that event.
+- Supervisors assign pool funds to registrations using the existing donation
+  assign/unassign flow, fully or partly.
+- An optional public progress bar shows "12 of 20 spots sponsored".
+
+### Plumbing
+
+- Sponsors get a receipt. They can optionally get a thank-you after the event
+  through Automations.
+- The Donations breakdown report gains a sponsorship pool column (received,
+  assigned, remaining) per event.
+- Recipients' identities are never shown to sponsors.
+
+---
+
+## 7. Ticket transfer
+
+Users can hand their ticket to someone else before the event.
+
+### How it works
+
+- From My Events, a user taps **Transfer** on a ticket, and enters the new
+  holder's name and email/phone.
+- The new holder gets the ticket by email/WhatsApp. If they don't have an
+  account, an inactive one is created with an activation link (same as guest
+  registration).
+- The **old QR code is invalidated** and a new one is issued, so screenshots
+  of the old ticket won't scan.
+- The original payer stays responsible for the registration (billing doesn't
+  move).
+
+### Rules
+
+- Allowed only before the event starts, and only for unredeemed tickets
+  (partially redeemed quantity tickets can't be transferred).
+- Can be disabled per event. Supervisors can always transfer.
+- If the event needs a form or parental consent, the new holder must complete
+  their own.
+- **Audit log:** transfer from, to, by whom and when. Offline scanning sync
+  flags any scan of a transferred ticket's old code.
+
+---
+
+## 8. Post-event feedback form
+
+An automatic survey sent after the event.
+
+### How it works
+
+- In the event wizard, a new **Feedback** step reuses the form builder, plus
+  new field types: **Rating (1–5 stars)** and **Multiple choice**.
+- Supervisors pick a **send time** (e.g. the morning after the event ends).
+  It's sent by the existing scheduled job to everyone who **checked in**, or
+  to all registrants, as chosen.
+- Responses can be anonymous or named (per event setting).
+- One automatic reminder after 3 days for anyone who hasn't responded.
+
+### Reporting
+
+- **New report: Feedback summary.** Response rate, average rating per
+  question, multiple-choice breakdown (bar charts), and a list of text
+  answers. Exports to PDF/Excel like other reports.
+- Ratings can be compared across events (e.g. Camp 2025 vs Camp 2026).
+
+---
+
+## 9. Group / room allocation
+
+Assign attendees to cabins, rooms, small groups, teams or buses. Built for
+camps and lockdowns.
+
+### How it works
+
+- Per event, supervisors create **allocation sets**, e.g. "Rooms", "Small
+  groups", "Buses". An event can have several sets.
+- Each set has **groups** with an optional **capacity**, an optional
+  **gender restriction** and an optional **leader** (a staff user).
+- **Drag-and-drop** board: unassigned attendees on the left, groups on the
+  right, with capacity counters.
+- **Auto-allocate:** fill groups evenly, respecting capacity and gender, and
+  optionally keeping registrations together (siblings) or splitting them
+  (friends).
+- Works per attendee, so it relies on group tickets (named attendees).
+
+### Outputs
+
+- Printable lists per group (with leader), and a master list.
+- Optionally show the group/room on the attendee's ticket and in My Events.
+- Group leaders (staff) can see their group's list, including medical
+  info if they're allowed to.
+- Bulk message by group ("Bus 2 leaves at 07:30").
+
+---
+
+## 10. Registration funnel stats
+
+Shows where people drop off between seeing an event and paying.
+
+### Funnel stages (per event)
+
+1. **Event page views** (unique visitors)
+2. **Registration started** (opened the registration page)
+3. **Registration submitted**
+4. **Paid** (fully paid or free)
+
+### How it works
+
+- Lightweight first-party tracking (no third-party analytics). Log page views
+  and stage events with an anonymous session ID. No personal data until the
+  user logs in or registers.
+- **New report: Registration funnel.** Count and conversion % at each stage,
+  over a date range, with a daily trend chart.
+- Optional breakdowns: by traffic source (UTM tags or short link alias, e.g.
+  `/camp-2025` vs direct), by device (mobile/desktop), and by ticket option.
+- A dashboard tile shows conversion % for active events.
+
+### Privacy
+
+Respect cookie consent. Aggregate raw page-view data after 90 days.
+
+---
+
+## 11. 2FA for Admins and Supervisors
+
+Two-factor authentication, **required** for Admin and Supervisor accounts.
+
+### How it works
+
+- **Method:** authenticator app (TOTP, e.g. Google Authenticator, Microsoft
+  Authenticator). WhatsApp code can be offered as a backup method since WAWP
+  is already set up.
+- **Enrolment:** on the next login after being given the Supervisor/Admin
+  role, the user must set up 2FA by scanning a QR code and confirming a code.
+- **Recovery codes:** 10 one-time codes shown once at setup, downloadable.
+- **Remember this device** for 30 days (optional, per login).
+- Optional for Staff and User roles, from Profile & Security.
+
+### Admin controls
+
+- Admins can **reset another user's 2FA** (e.g. a lost phone). This revokes
+  their sessions and forces re-enrolment.
+- Security event log entries: 2FA enabled, disabled, reset, recovery code
+  used, failed code attempts.
+- Failed 2FA attempts count toward the existing login lockout.
+- The setup wizard enrols the first admin in 2FA.
+
+---
+
+## 12. Admin "impersonate user"
+
+Lets an Admin see the site exactly as a specific user sees it, to debug
+problems ("my ticket isn't showing").
+
+### How it works
+
+- From Manage users, an Admin taps **Impersonate** on a user and must enter a
+  **reason** (required).
+- A short-lived session is created (max 30 minutes) that acts as the user.
+- A **bright banner on every page**: "Viewing as [Name]. [End impersonation]".
+
+### Safety rules
+
+- **Read-only by default.** Payments, refunds, cancellations, password/email
+  changes, deleting data, giving consent and sending messages are blocked
+  while impersonating.
+- Can't impersonate another Admin.
+- Requires 2FA to be active on the admin's account.
+- **Audit log:** start, end, reason, and every page/action during the
+  session.
+- Optional: notify the user that an admin viewed their account (an
+  organisation-level setting).
+
+---
+
+## Suggested build order
+
+| Phase | Features | Why |
+|-------|----------|-----|
+| 1 | 2FA, Coupon codes | Security first. Coupons are self-contained and give an immediate win for staff. |
+| 2 | Group tickets | Foundation for consent, transfer and room allocation (named attendees). |
+| 3 | Parental consent, Waitlist | The biggest wins for youth events. |
+| 4 | Offline scanning, Ticket transfer | Door-day reliability. Transfer must exist before offline sync handles it. |
+| 5 | Group/room allocation, Sponsor a spot | Camp-specific and bursary support. |
+| 6 | Feedback form, Funnel stats, Impersonate user | Insights and support tooling. |
+
+Each phase should add matching help content (`frontend/src/content/help/`),
+audit log entries, a CHANGELOG entry, and updates to FEATURES.md and
+SETTINGS.md.

+# Handover — where things stand and how to carry on
+
+Last updated: 2026-10-23, after **1.37.2**. The plan itself is in
+[ROADMAP-v2.md](./ROADMAP-v2.md) (decisions table at the end); the previous round of
+features is in [FEATURES-ROUND-1.md](./FEATURES-ROUND-1.md).
+
+## Done so far (road to 2.0)
+
+| Version | What |
+|---------|------|
+| 1.32.0 | Early-bird ribbon on event cards |
+| 1.33.0 | Multi-day events phase A — sessions, late joining + late pricing, per-session check-in, attendance register, session reminders, certificates (4 templates, verify page) |
+| 1.34.0 | Background jobs on pg-boss (admin Background jobs page), Playwright e2e tests, Gitea CI workflow, `scripts/deploy.sh` |
+| 1.35.0 | Multi-day events phase B — "pick sessions" (per-session tickets and prices, session capacity) |
+| 1.37.2 | Payment status checks (PayFast transaction history; job every 15 min; Payments → Reconcile → Waiting for payment), PayFast Test connection |
+| 1.37.1 | "Pay online" hidden when no provider is on or under R15; SnapScan/Zapper dropped from the roadmap |
+| 1.37.0 | PayFast (signed form, ITN checks), `ProviderCheckout` with amount checks, the "Pay online" page (`/pay/<id>`) where payers choose a provider |
+| 1.36.0 | Payment provider interface (`backend/src/payments`) with Yoco behind it, `ProviderTransaction`, `Payment.provider`, Site settings → Payments (on/off and order per provider), R15 minimum |
+| 1.35.1 | Waitlist per session, session picker at the door, "All sessions" tickets let people tick sessions at one price; fixes (per-session stock limits, offline service worker serving stale scripts) |
+
+## Next up
+
+1. **1.38.0–1.39.0 — POPIA toolkit** (spec §3 in the roadmap).
+2. **1.40.0 + Hub v1** — install/update tooling and the Hope Events Hub (separate repo
+   `joshua/hope-events-hub`).
+
+## Working on this repo
+
+- **Release routine:** branch `feat/<name>` → commit → bump with
+  `npm version X.Y.Z --no-git-tag-version` in `.`, `backend` and `frontend` → add the
+  `## [X.Y.Z] - date` heading under `[Unreleased]` in CHANGELOG.md → `git merge --no-ff`
+  into `main` → `git tag vX.Y.Z` → `git push origin main <branch> vX.Y.Z`. One minor
+  version per feature.
+- **Changelog:** add entries to `[Unreleased]` as you go, in plain language.
+- **Docs to keep in step:** CHANGELOG.md, FEATURES.md, README.md, SETTINGS.md,
+  backend/API_DOCUMENTATION.md, the `/docs` route list in `backend/src/index.js`, and
+  in-app help in `frontend/src/content/help/` (register new pages in `registry.ts`).
+- **Prisma migrations:** `npx prisma migrate dev --create-only --name x` against a local
+  DB. Prisma 7 keeps adding an unrelated `_EventNotifyRecipients` primary-key/index
+  change — delete those two blocks from the generated SQL. It also rewrites the comment
+  in `migration_lock.toml`; `git checkout` that file back. New `AdminAuditAction` values
+  need a migration.
+- **Server Node version:** the deployment notes install Node 20, so dependencies must
+  support Node 20 (that's why pg-boss is pinned to 10.x).
+- **Pushing:** pushing from some shells fails with "Failed to authenticate user" (a stale
+  saved credential); pushing from your own terminal works.
+
+## Tests
+
+- Backend unit tests: `cd backend && npm test` (Jest).
+- PayFast e2e (`e2e/payfast.spec.ts`) pays into a real PayFast sandbox account and is skipped
+  unless `E2E_PAYFAST_MERCHANT_ID`, `E2E_PAYFAST_MERCHANT_KEY` and `E2E_PAYFAST_PASSPHRASE` are
+  set (from the Sandbox dashboard). PayFast's documented public test merchant (10000100) no
+  longer accepts payments. ITNs can't reach localhost; they're covered by unit tests
+  (`backend/tests/payments.test.js`) — to try one for real, use a tunnel, a public
+  `BACKEND_URL` and `PAYFAST_SKIP_IP_CHECK=true`.
+- End-to-end: `npm run test:e2e` from the repo root (first time: `npm install` and
+  `npx playwright install chromium`). They start their own backend (5100) and
+  frontend (3100) against `<your DATABASE_URL database>_e2e`, which is dropped and
+  re-seeded every run (`e2e/support/prepare-db.js`). The DB user must be able to
+  create databases. ~5 minutes in dev mode.
+  Locally, Playwright reuses servers already running on 5100/3100. If the run times out
+  waiting for the frontend (the home page returns 500 until the e2e backend is up), start
+  them yourself — `node e2e/support/prepare-db.js`, then the backend from `backend/`
+  with `PORT=5100`, the e2e `DATABASE_URL`, `JOBS_ENABLED=false`,
+  `TWO_FACTOR_REQUIRED_ROLES=false`, and `npx next dev -p 3100` from `frontend/` with
+  `NEXT_DIST_DIR=.next-e2e NEXT_PUBLIC_API_URL=http://localhost:5100` — then run
+  `npx playwright test`. Don't edit frontend files while it runs.
+- **Careful with ad-hoc scripts against a dev/test database that has SMTP set up:**
+  registrations and check-ins send real email/WhatsApp. Use made-up `@test.local`
+  people only.
+- CI: `.gitea/workflows/ci.yml` runs everything once a Gitea Actions runner is
+  registered (none yet). Tag deploys need the `DEPLOY_HOST`, `DEPLOY_USER`,
+  `DEPLOY_SSH_KEY` (+ optional `DEPLOY_PATH`) secrets.
+
+## Where the multi-day code lives
+
+- `backend/src/utils/sessions.js` — all session rules (dates, check-in window, late
+  pricing, pick sessions, capacity, grouping); unit tests in `backend/tests/sessions.test.js`.
+- `backend/src/utils/certificates.js`, `sessionReminders.js`,
+  `controllers/attendanceController.js` (register + certificates API).
+- `backend/src/jobs/index.js` — the background job registry.
+- Frontend: `src/lib/sessions.ts`, `src/components/events/ScheduleEditor.tsx`,
+  `SessionPicker.tsx`, `SessionSchedule.tsx`, `src/app/dashboard/supervisor/attendance/`.
+
+## Where the payment code lives
+
+- `backend/src/payments/index.js` — the provider registry and the `PaymentProvider` interface
+  (documented at the top), provider on/off and order (AppSetting `payment_providers`), the R15
+  minimum, and `createCheckout`. Tests: `backend/tests/payments.test.js`.
+- `backend/src/payments/providers/yoco.js` — Yoco: checkouts, webhook signature check, webhook
+  parsing. Keys/webhook admin stays in `utils/yoco.js` + `controllers/yocoController.js`.
+- `backend/src/payments/webhook.js` — shared webhook processing (Payment with `provider`,
+  donation split, registration status, tickets, emails, `ProviderTransaction`).
+- `backend/src/payments/checkouts.js` — registration checkouts (balance, part, + donation).
+- `backend/src/payments/status.js` — status checks for notifications that never arrived
+  (`payment-status` job, Payments → Reconcile → "Waiting for payment"). PayFast looks payments
+  up in its transaction history (`findPayments`); Yoco's Checkout API documents no lookup, so
+  Yoco checkouts are "can't check". Tests: `backend/tests/paymentStatus.test.js`.
+- **Adding a provider:** write `providers/<id>.js` with the same interface, add it to
+  `PROVIDERS` in `index.js`, mount `handleProviderWebhook('<id>')` at `/api/webhooks/<id>`
+  (`routes/webhookRoutes.js`), and give it a settings card in
+  `frontend/src/components/admin/PaymentsTab.tsx`. New providers start switched off.
+- `Payment.method` stays the wallet type (card, apple_pay…) because cashups bucket on it;
+  the provider is `Payment.provider`.
+
+## Known gaps / follow-ups
+
+- At the door, per-session tickets are booked on new registrations only; editing an
+  existing registration leaves its booked sessions as they are (the backend refuses
+  changes to picked lines). "Add & charge" for a session at the scanner isn't built.
+- Ticket scanning by camera isn't covered by the e2e tests (headless browsers have no
+  camera); scans are tested through the API.

+# Hope Events — Road to 2.0.0
+
+Planned features and platform work to take Hope Events from 1.32.x to 2.0.0.
+Each section covers what the feature does, who uses it, how it fits the
+existing platform, and the edge cases to handle. See [FEATURES.md](../FEATURES.md)
+for what already exists, and [FEATURES-ROUND-1.md](./FEATURES-ROUND-1.md) for the
+previous round (1.12.0 – 1.23.0). Where to pick up: [HANDOVER.md](./HANDOVER.md).
+
+**Theme for 2.0:** turn a feature-rich church app into a product that can be
+sold — trustworthy (POPIA), flexible (multi-day events, several payment
+providers), and maintainable (tests, CI, typed backend, versioned API).
+
+**Status (2026-10-23):** all features in this document are approved. Shipped
+so far: 1.32.0 early-bird ribbon on event cards; 1.33.0 multi-day events
+phase A (sessions, late joining, per-session check-in, attendance register,
+reminders, certificates); 1.34.0 job queue (pg-boss), Playwright E2E tests, Gitea CI
+workflow (waiting for a runner) and deploy script; 1.35.0 multi-day events phase B
+(pick sessions, per-session capacity), with 1.35.1 adding the per-session waitlist, the session
+picker at the door and session choice on "All sessions" tickets; 1.36.0 payment provider interface
+(Yoco moved behind it, Site settings → Payments); 1.37.0 PayFast and the "Pay online" page;
+1.37.1 "Pay online" hidden when it can't be used; 1.37.2 payment status checks for missing
+notifications. SnapScan and Zapper are dropped — Yoco and PayFast are enough (2026-10-23).
+**Next: 1.38.0 POPIA toolkit.**
+
+**Repositories:**
+
+| Repo | What |
+|------|------|
+| `joshua/hope-events` (this repo) | The church app. Everything in this document except the Hub app itself — including the Hub *client* (licence step, "Connect to Hub", heartbeat, licence checks) |
+| `joshua/hope-events-hub` (new) | The Hub app (§13): its own versions, CHANGELOG, releases and server |

+
+## 1. Multi-day events (sessions)
+
+One event that runs over several dates, e.g. **"Alpha Course — every Wednesday
+18:30–20:30 for 5 weeks"**, a 3-day conference, or a camp with an evening
+session each day. People register and pay **once**, get **one ticket**, and are
+checked in **per session**.
+
+> Not the same as [Event series](#6-event-series-and-cloning). A series groups
+> *separate* events (Camp 2026, Camp 2027) that each have their own
+> registrations. Sessions are dates *inside one* event.
+
+**Who:** Supervisors set up the schedule. Users see it on the event page, in
+their tickets and in their calendar. Staff check in per session.
+
+### Event setup
+
+New **Schedule** section on the event form:
+
+| Setting | Options |
+|---------|---------|
+| Schedule type | Single date (today's behaviour) · Multiple sessions |
+| Pattern builder | Repeat **daily / weekly / every N weeks** on chosen weekday(s), start date, time from–to, **number of sessions** or **until date** |
+| Generated sessions | Editable list: change date/time/location/label of any one session, delete, or add an extra one-off date |
+| Session label | Optional, e.g. "Week 1 — Is there more to life?" (defaults to "Session 1, 2, …") |
+| Session location | Optional; falls back to the event location |
+| Attendance mode | **Whole course** (one registration covers all sessions) · **Pick sessions** (see phase B below) |
+| Late joining | Per event: Off (registration closes when the first session starts) · Allow until the start of session N |
+| Late-joiner price | Per event, only when late joining is on: Full price · **Pro-rata** (price × remaining sessions ÷ total sessions, rounded to the **nearest R10**, e.g. R183 → R180, R185 → R190) · Fixed late price |
+| Check-in window | Per event: **Whole day** (default — any time on the session's date, in case someone was let in without being scanned) · Session time only (2 h before start until the session ends) |
+| Session reminders | Per event, **off by default**: when on, choose timing (e.g. 3 h before, the day before at 18:00, or both) and channels (email / WhatsApp) |
+| Certificates | Per event, **off by default**: when on, choose a template and the completion rule (see [Certificates](#certificates)) |
+
+The pattern builder is only a helper: it generates rows, then the session list
+is the source of truth. Typing "every Wednesday for 5 weeks" and then skipping
+a public holiday is just deleting one row.
+
+### How it works
+
+- `Event.startDate` / `endDate` **stay** and are kept in sync automatically
+  (first session start, last session end). Everything that already reads them —
+  consent age checks, transfer cut-off, early-bird, feedback timing, ICS,
+  listings, sitemap — keeps working unchanged. Only places that need
+  per-session behaviour are updated.
+- **Public event page:** shows the full schedule, with past sessions greyed out
+  and a "Next session" highlight. Event cards show "5 sessions · Wed 4 Nov –
+  Wed 2 Dec".
+- **Event listings:** a multi-session event stays "upcoming / running" until
+  its **last** session ends, and sorts by its **next** session.
+- **Tickets (PDF, email, WhatsApp):** list all session dates. One QR code.
+- **Calendar (ICS):** one VEVENT per session (not an RRULE, so edited or
+  skipped sessions are exact).
+- **Check-in:** the scanner auto-selects today's session (on a day with more
+  than one session, the one happening now or next), with a dropdown to
+  override. Whether a scan is accepted depends on the event's **check-in
+  window** (whole day or session time only). A ticket can be checked in
+  **once per session** (per person for group tickets). Scanning again in the
+  same session shows "Already checked in for Session 3 at 18:42".
+- **Manual check-in:** supervisors can tick someone as present for a session
+  from the attendance register afterwards (e.g. let in without a scan), logged
+  in the audit log with who marked it.
+- **Reminders:** off by default; when switched on for the event, a reminder
+  goes out before **each** session (email/WhatsApp, via the scheduled-message
+  worker), e.g. "See you tonight at 18:30".
+- **Late joiners:** when late joining is on, the registration page shows which
+  sessions are left and the late price ("3 of 5 sessions left — R180").
+- **Changes:** moving or cancelling a session after people registered prompts
+  the supervisor to notify registrants (pre-filled broadcast), and updates the
+  ICS/tickets.
+
+### Phase B: pick sessions (drop-in)
+
+Second step, released separately. Lets people register for **some** sessions,
+e.g. a conference where each day is sold separately or a weekly drop-in class.
+
+- Ticket options can be scoped to sessions: "Day pass (pick days)" priced per
+  session, "Full conference pass" covering all.
+- Optional **capacity per session** on top of the option stock limit.
+- The ticket stores which sessions it covers; scanning on a session it doesn't
+  cover shows "Not registered for this session" (with "Add & charge" at the
+  door for supervisors).
+- Waitlist works per session when sessions have their own capacity.
+
+### Reporting
+
+- **Attendance register:** grid of attendees × sessions with ticks, totals per
+  session, attendance % per person. Export to Excel and PDF.
+- **Completion filter:** "attended at least 4 of 5" — useful for certificates
+  and for follow-up ("missed the last 2 weeks").
+- Daily summary email includes "Sessions today".
+- Funnel stats unchanged (they are per event).
+
+### Certificates
+
+Optional completion certificates (PDF), chosen per event.
+
+- **3–4 built-in templates**, e.g. *Classic* (border, serif), *Modern* (clean,
+  accent colour bar), *Church* (logo-led, scripture line), *Kids* (playful,
+  for children's programmes). All use the site logo and brand colour from Site
+  settings.
+- **Event settings:** Certificates on/off · Template · Title ("Certificate of
+  Completion") · Body text with placeholders (`{name}`, `{event}`,
+  `{sessionsAttended}`, `{totalSessions}`, `{endDate}`) · Signature name and
+  role (optional uploaded signature image) · **Completion rule**: attended at
+  least N sessions or N % (default: all sessions).
+- **Preview** button in the event form renders a sample PDF.
+- **Who gets one:** attendees meeting the completion rule after the last
+  session. Supervisors can issue/withdraw one manually (audit logged).
+- **Delivery:** download from My Events, bulk download (ZIP) from the
+  attendance register, and optional email/WhatsApp send.
+- Each certificate has a short verification code + QR linking to a public
+  "certificate valid" page (name, event, date only).
+- Generated with `pdfkit`, like tickets and receipts (`utils/pdfDocs.js`).
+- Also usable on single-date events (completion = checked in).
+
+### Edge cases
+
+| Case | Behaviour |
+|------|-----------|
+| Delete a session that has check-ins | Blocked; offer **Cancel session** instead (kept for history, hidden from schedule, excluded from attendance %) |
+| Switch Multiple → Single after registrations | Allowed only if no session check-ins exist |
+| Ticket transfer | Allowed until the **first** session starts (current rule). Optional later: allow mid-course transfers with check-in history kept on the original holder |
+| Parental consent | Age is measured at the first session (current `startDate` rule) |
+| Medical details deletion | Runs after the **last** session (end date), as today |
+| Feedback form | Sent after the last session |
+| Cashup | Still per event. At-the-door cash per session is captured with the session on the payment so reports can split it |
+| Offline scanning | Session list and per-session usages are part of the offline lock bundle; sync keeps the session id per scan |
+| Timezones | Sessions stored as UTC instants, same as `Event.startDate` today (see `icsUtils.js`) |
+| Session overlaps / out of order | Allowed (conferences have parallel tracks later), list always sorted by start |
+| Kiosk / At the door | Shows the current session; check-in counts against it |

+
+- Session CRUD + pattern generator in `backend/src/utils/sessions.js` with
+  Jest tests (DST-free but still test month boundaries, skipped dates, "until"
+  vs "count").
+- Scan endpoint takes an optional `sessionId`; defaults to the current session.
+- Help content, audit log entries (session created/moved/cancelled),
+  CHANGELOG, FEATURES.md, SETTINGS.md.

+## 2. Payment providers: PayFast
+
+Add **PayFast** next to Yoco, and let the admin **enable one or both** in Site
+settings. At checkout the user picks from the enabled ones. (Shipped in
+1.36.0–1.37.2. SnapScan and Zapper were planned too, but dropped on 2026-10-23:
+two providers are enough.)
+
+**Who:** Admins configure providers. Users choose at payment. Supervisors
+reconcile.
+
+### Site settings → Payments
+
+| Setting | Options |
+|---------|---------|
+| Providers | Yoco · PayFast — each with an **Enabled** toggle |
+| Credentials | Per provider (merchant id/key, API key, passphrase, webhook secret…), stored encrypted (`utils/encryption.js`, same as WhatsApp) |
+| Mode | Live / Sandbox per provider (where supported) |
+| Display order / default | Which one is shown first. Default order: Yoco · PayFast |
+| Minimum amount | **R15 for all providers** (one site-wide minimum for online payments) |
+
+**Fees are not handled automatically.** Payments are recorded at the full
+amount paid; provider fees are not deducted, estimated or added to the payer's
+total. Fees are dealt with by people during **cashup**, as today. There is no
+"pass fee to payer" option.
+
+"Test connection" button per provider, like the WhatsApp setup.
+
+### How it works
+
+- A single **PaymentProvider interface** in the backend:
+  `createCheckout`, `handleWebhook` (verify signature → mark paid),
+  `getTransaction`, `refund` (if the provider supports it via API),
+  `listTransactions` (for reconciliation).
+- Yoco is moved behind the same interface first (no behaviour change), then
+  PayFast is added.
+- `Payment.method` gets the provider name; `YocoTransaction` is generalised to
+  `ProviderTransaction` (`provider` column) so the existing reconciliation page
+  works for all providers.
+- Refunds: if the provider has no refund API, the supervisor refunds in the
+  provider's portal and records it here (existing manual refund flow).
+
+### Edge cases
+
+- Provider disabled while a checkout is in progress → webhook still accepted
+  and processed.
+- Duplicate / late webhooks → idempotent on the provider's transaction id.
+- Webhook never arrives → "Check payment status" button and a periodic
+  reconcile job.
+- Amount mismatch (user edits amount in app) → payment held as "needs review".
+- Only enabled providers appear in kiosk / self-service.
+- Amount below R15 → online payment options hidden, with a message to pay at
+  the door / contact the organiser.
+- **Before building each one:** get the documentation links from Joshua and
+  confirm current API docs for webhooks, sandbox, refunds and QR deep-link
+  support.
+
+---
+
+## 3. POPIA toolkit
+
+Tools that make the platform **POPIA-ready** out of the box. This is the main
+selling point for other churches and organisations: "your attendee data is
+handled properly, and you can prove it."
+
+> This is tooling to support compliance, not legal advice. Wording and
+> retention periods should be checked by whoever is the customer's
+> Information Officer.
+
+**Who:** Admins (and the appointed Information Officer) manage it. Users get
+self-service privacy tools.
+
+### For users (data subjects)
+
+- **Privacy centre** in My account:
+  - **Download my data** — JSON + readable PDF of profile, registrations,
+    payments, tickets, form answers, consents, messages sent.
+  - **Correct my data** — edit profile; request correction of locked records.
+  - **Delete my account** — creates a deletion request (see below).
+  - **Communication preferences** — email / WhatsApp / marketing opt-in with
+    timestamps (extends the existing notification preferences).
+- **Unsubscribe link** in every bulk email and an opt-out keyword for bulk
+  WhatsApp. Opted-out users are skipped automatically in broadcasts.
+- **Privacy notice acceptance** — versioned; users accept the current version
+  at registration, and are asked again when it changes.
+
+### For admins
+
+| Tool | What it does |
+|------|--------------|
+| Information Officer | Name, contact details, shown on privacy notice and contact page |
+| Privacy notice editor | Versioned text, published version history |
+| Consent log | Who consented to what, when, which notice version, how (web, kiosk, WhatsApp) |
+| Data requests inbox | Access, correction and deletion requests with status, due dates and audit trail |
+| Deletion workflow | Admin approves → personal info is **anonymised**; financial records kept (amounts, dates) but unlinked from the person, as tax law requires them to be kept |
+| Retention policies | Per data category (inactive accounts, form answers, medical details, analytics, audit log, backups): keep for N months, then anonymise/delete via nightly job. Sensible defaults shipped |
+| Operator register | List of third parties that process data (Yoco/PayFast/…, WhatsApp provider, email provider, Sentry, hosting) with purpose; feeds the privacy notice |
+| Access log | Who exported or viewed personal data in bulk (exports, attendee lists, medical details) |
+| Breach register | Record a security compromise, affected users, actions taken; templates for notifying users and the Information Regulator |
+| Children's data | Already covered by parental consent; flagged as special/children's info in reports |
+| POPIA readiness page | Checklist with score: officer set, notice published, retention set, operators listed, unsubscribe working… |
+
+### Edge cases
+
+- Deletion of a user with an open registration / upcoming event → request
+  waits until after the event, or the admin cancels and refunds first.
+- Anonymised users still count in historic reports ("Deleted user").
+- Backups contain deleted data until they age out — stated in the notice;
+  backup retention is one of the retention policies.
+- Impersonation and exports must be logged in the access log.
+
+---
+
+## 4. Kids check-in with security labels
+
+A secure check-in/check-out flow for children's ministry and youth events.
+**Builds on sessions (§1), attendees, parental consent and allocation groups.**
+
+**Who:** Parents check in children (self-service kiosk or staff desk).
+Kids-ministry staff run rooms. Supervisors set up rooms.
+
+### How it works
+
+- Parent finds their family (phone number / QR from My account) and ticks the
+  children being dropped off. New children can be added on the spot.
+- The system prints **two labels**:
+  - **Child label:** name, room, allergy/medical icons, short pickup code.
+  - **Parent label:** the same pickup code.
+- **Check-out** requires scanning or typing the matching code. A mismatch
+  alerts the room leader.
+- Rooms come from allocation groups (age/grade rules), with **ratios** (e.g.
+  1 leader per 5 toddlers) and live room counts.
+- **Page a parent:** room leader taps "Call parent" → WhatsApp/SMS to the
+  parent ("Please come to the Toddlers room").
+- Attendance per child per session feeds the attendance register.
+
+### Plumbing / edge cases
+
+- Label printing via browser print with label-size CSS (Dymo / Brother label
+  printers, 62 mm and 89×36 mm presets); PDF fallback.
+- Allergies and medical info come from the consent/medical fields; respect
+  the medical-info deletion rules.
+- Custody notes ("Do not release to …") visible to room leaders only.
+- Works on the existing offline-scanning foundations for flaky Wi-Fi.
+
+---
+
+## 5. Volunteer / serving rosters
+
+Plan who serves where, for an event or each session.
+
+- **Serving roles** per event/session: Welcome, Parking, Kids, Sound, Kitchen…
+  with the number of people needed.
+- Volunteers **sign up** for open slots, or supervisors **assign** people.
+- Reminders via email/WhatsApp before their slot; "can't make it" → swap
+  request to others in the role.
+- **Volunteer check-in** on the day (separate from attendee check-in).
+- Volunteers can get a free/discounted ticket automatically (uses coupons/comp).
+- Reports: roster sheet per session, fill rate, hours served per person.
+
+---
+
+## 6. Event series and cloning
+
+- **Clone event:** copy an event with its options, variants, early-bird tiers,
+  forms, consent text, feedback form, cost template, allocation groups and
+  sessions (dates shifted to the new start). No registrations.
+- **Series:** group separate events (Camp 2025, Camp 2026; monthly Men's
+  Breakfast) on one series page, with "Next in this series" and a series
+  follow/notify option.
+- **Year-on-year reports:** registrations, income and attendance compared
+  across events in a series.
+- **Season pass:** a bundle across events in a series (extends event bundles).
+
+---
+
+## 7. Apple and Google Wallet tickets
+
+- "Add to Apple Wallet" / "Add to Google Wallet" buttons next to the PDF
+  ticket, in email and in My Events.
+- Pass shows event, date (next session for multi-day), location, holder name,
+  QR code.
+- Passes **update** when the event/session changes (time, venue, cancelled).
+- Requires an Apple Developer account (pass signing certificate) and a Google
+  Wallet issuer account; both configured in Site settings and **optional** —
+  hidden when not configured.
+
+---
+
+## 8. Outbound webhooks
+
+Let other systems react to what happens in Hope Events.
+
+- Admin adds endpoints and picks events: `registration.created`,
+  `registration.paid`, `registration.cancelled`, `payment.refunded`,
+  `ticket.checked_in`, `user.created`, `event.published`…
+- Payloads signed with HMAC (secret per endpoint), retries with back-off,
+  delivery log with "Resend".
+- Enables integrations (ChurchSuite, Planning Center, Google Sheets via
+  Zapier/Make) without building each one. Native integrations can follow later.
+
+---
+
+## 9. Admin dashboard, command palette, bulk actions
+
+- **Dashboard** as supervisors' home: today's events/sessions, check-ins so
+  far, money in (today/week), pending items (unreconciled payments, consent
+  outstanding, waitlist offers, data requests), alerts.
+- **Command palette (Ctrl+K):** jump to any event, user, registration,
+  ticket or setting; quick actions ("New event", "Find payment R450").
+- **Bulk actions** on registration/attendee lists: message, export, mark
+  paid, move option, cancel, allocate.
+- **Saved filters** per user on list pages.
+
+---
+
+## 10. Languages (Afrikaans first)
+
+- i18n framework on the frontend (e.g. `next-intl`); English + Afrikaans.
+- User language preference; emails, WhatsApp messages and PDFs sent in the
+  user's language, with per-language templates.
+- Event content stays as typed by the supervisor (optional translated title /
+  description fields later).
+
+---
+
+## 11. Accessibility pass (WCAG 2.2 AA)
+
+- Audit public pages, registration, payment, My Events and the kiosk.
+- Keyboard navigation, focus states, labels, colour contrast (light and
+  dark), screen-reader names for icon buttons, error messages linked to
+  fields.
+- Automated `axe` checks in the Playwright suite so it doesn't regress.
+
+---
+
+## 12. Multi-campus (one install per church)
+
+**Decision: one install per church.** Each customer gets their own install
+and database (the `/setup` wizard already makes this possible). This gives
+full data separation — which also helps the POPIA story — and lets each
+church run on a different server. **True multi-tenant is out of scope.**
+
+**Multi-campus** is in scope: one church with several campuses inside one
+install.
+
+### Setup
+
+- Site settings → **Campuses**: off by default. When on, admins add campuses
+  (name, address, contact, optional logo/colour accent, default location for
+  events).
+- Single-campus churches never see campus fields anywhere.
+
+### How it works
+
+- **Events** belong to one campus, or to **All campuses** (church-wide
+  conferences, camps).
+- **Public site:** campus filter on the events list, remembered per visitor;
+  campus shown on event cards and tickets. Optional campus landing pages
+  (`/campus/<slug>`).
+- **Users** can set a home campus (used as the default filter and for
+  broadcasts). Accounts stay shared across campuses — one login for the
+  church.
+- **Campus-scoped roles:** a supervisor or staff member can be limited to
+  one or more campuses (sees and manages only those events, registrations,
+  scanning, cashups). Admins and unscoped supervisors see everything.
+- **Reports, cashup, dashboard, funnel stats:** filter by campus plus a
+  church-wide total.
+- **Broadcasts:** target "everyone at campus X".
+- **Kids check-in rooms** and **volunteer roles** are per campus.
+- **Notification recipients** per campus (e.g. the campus pastor gets that
+  campus's daily summary).
+
+### Edge cases
+
+- Turning campuses off with campus data present → hidden, not deleted.
+- Deleting a campus with events → blocked; archive instead.
+- Moving an event to another campus → scoped supervisors of the old campus
+  lose access; logged in the audit log.
+
+### Data model (sketch)
+
+```prisma
+model Campus {
+  id        String   @id @default(uuid())
+  name      String
+  slug      String   @unique
+  address   String?
+  isActive  Boolean  @default(true)
+  order     Int      @default(0)
+  events    Event[]
+}
+// Event.campusId String? (null = all campuses)
+// User.homeCampusId String?
+// UserCampusScope { userId, campusId } — empty = unscoped
+```
+
+### Running many installs
+
+Because every church is a separate install, a few tools make that manageable:
+
+- **Install script:** fresh server → Node, Postgres, PM2, reverse proxy,
+  `.env`, migrations, then `/setup` in the browser.
+- **Update script:** pull a tagged version, back up the database, run
+  migrations, build, restart; roll back on failure.
+- **Version and health:** current version shown in admin and on a `/health`
+  endpoint (version, DB, jobs, last backup), reported to the
+  [Hub](#13-central-management-platform-hope-events-hub).
+
+---
+
+## 13. Central management platform (Hope Events Hub)
+
+A separate app, run by Joshua, to see and manage **every Hope Events
+install** from one place: who the customers are, which version each runs,
+whether they're healthy, basic usage stats, and their **licence** status.
+
+**Who:** Joshua (and any future support staff). Customers never log in to it.
+
+### Separate app, separate repo, separate server
+
+- **Its own git repository:** `joshua/hope-events-hub` on the same Gitea
+  server (c-git.crosscode.co.za), with its own semver tags, CHANGELOG and
+  deploys. It is never shipped to churches, so none of its code (customers,
+  licence signing key, other churches' data) ends up on a customer's server.
+- Same stack (Next.js + Express + Prisma + Postgres) so it's familiar.
+- **What lives where:**
+  - Hub repo: dashboard, customers, licences, licence **signing** (private
+    key — only ever on the Hub server), `/api/installs/register` and
+    `/api/installs/heartbeat` endpoints, alerts.
+  - Hope Events repo: the Hub **client** — licence step in `/setup`,
+    "Connect to Hub" in Site settings, heartbeat job, licence verification
+    with the Hub's **public** key, read-only mode, banners.
+- **The contract between them** (register / heartbeat payloads, licence token
+  format) is versioned with a `protocolVersion` field and documented in both
+  repos (`docs/hub-protocol.md`). The Hub accepts the current and previous
+  protocol version, so churches on older versions keep reporting while they
+  wait to update.
+- Runs on its own server/domain (e.g. `hub.<your-domain>`). If the Hub is
+  down, **no church install is affected**.
+- Hope Family Church's own site is the first registered install.
+
+### Registration (setup → Hub)
+
+1. The `/setup` wizard gets a **Licence** step: the customer enters the
+   **licence key** Joshua issued (created in the Hub first).
+2. When setup completes, the install sends `POST /api/installs/register`
+   with: licence key, site name, URL, admin contact, version, server info
+   (Node/Postgres version, OS), timezone, enabled features.
+3. The Hub checks the key, links the install to the customer, and returns an
+   **install id + install secret** (stored encrypted in AppSettings) and a
+   **signed licence token**.
+4. Existing installs (already past setup) get a **"Connect to Hub"** button
+   in Site settings → Licence.
+
+All later calls are signed with the install secret (HMAC) and go over HTTPS.
+
+### Heartbeat (install → Hub)
+
+- Every 15 minutes (job queue) the install POSTs a heartbeat:
+  - **Health:** version, uptime, DB OK, job queue OK, last successful
+    backup, disk free, last error count (from Sentry or local logs), pending
+    migrations.
+  - **Basic stats (aggregate counts only):** users, active/upcoming events,
+    registrations and tickets (30 days / all time), check-ins, WhatsApp/email
+    sent, enabled payment providers, campuses on/off.
+  - **Optional (off by default, customer chooses):** payment totals.
+- **Install → Hub only.** The install pushes; the Hub never needs to reach
+  into the install, so it works behind firewalls and the Hub has no access
+  to church data.
+- **No personal information is ever sent** (no names, emails, phones,
+  attendee data). Listed in the install's POPIA operator register and
+  privacy notice as "aggregate usage statistics to the software provider".
+
+### Hub dashboard
+
+- **Installs list:** customer, URL, version (flag if behind the latest tag),
+  licence status, last heartbeat (red if > 1 h ago), health status.
+- **Install detail:** health history, stats charts, version history,
+  licence history, notes, contacts.
+- **Alerts** (email/WhatsApp to Joshua): install offline > 1 h, backup
+  failed or older than 48 h, disk low, errors spiking, licence expiring.
+- **Releases:** latest version and changelog; installs see "Update
+  available" in their admin.
+- **Customers:** contact details, plan, licence(s), billing notes.
+
+### Licences
+
+| State | What the install does |
+|-------|----------------------|
+| **Active** | Everything works |
+| **Grace** (expired or Hub unreachable) | Everything works; admins see a banner "Licence needs renewing — X days left". Default 14 days |
+| **Suspended** | **Read-only:** no new events, no new registrations or payments. Existing tickets **still scan**, and admins can still view and **export all data** |
+| **Revoked** | Same as suspended, with a permanent banner |
+
+- Joshua turns a licence on/off, sets expiry dates and plan in the Hub; the
+  install picks up the change on its next heartbeat.
+- The licence is a **signed token** (Ed25519: the Hub signs with its private
+  key, installs only hold the public key). Installs verify it **offline**, so
+  a Hub outage never switches a church off, and a token can't be faked by
+  editing the database.
+- **Never a hard kill:** a church must always be able to scan tickets for
+  events people already paid for, and get its own data out (POPIA access
+  rights). Suspension blocks *new* activity only.
+- Optional plan limits later (e.g. number of campuses, WhatsApp) carried in
+  the token.
+
+### Things to be aware of
+
+- Code runs on the customer's server, so a determined developer could patch
+  out the licence check. Real protection is the **contract** plus updates and
+  support only being available to valid licences — the licence check keeps
+  honest customers honest.
+- The Hub should not offer remote commands (run updates, impersonate,
+  database access) in v1: it's the most valuable target an attacker could
+  hit, so keeping it read-only toward installs keeps every church safe if it
+  is ever compromised. Remote "trigger update" can be revisited later.
+- The Hub itself needs 2FA, backups and the same audit log approach.
+
+### Data model (Hub, sketch)
+
+```prisma
+model Customer { id, name, contactName, email, phone, notes, licences, installs }
+model Licence  { id, customerId, key, plan, status, expiresAt, graceDays, issuedAt }
+model Install  { id, customerId, licenceId, name, url, secretHash, version,
+                 lastHeartbeatAt, health Json, registeredAt }
+model Heartbeat { id, installId, receivedAt, version, health Json, stats Json }
+                 // rolled up to daily after 30 days
+model InstallEvent { id, installId, type, message, createdAt } // alerts, version changes
+```
+

+
+## 14. Foundations (platform work)
+
+Not visible to users, but this is what makes 2.0 a safe product to sell and
+keep adding to.
+
+| Item | What |
+|------|------|
+| CI (Gitea Actions) | Lint, typecheck, Jest, build on every push; deploy on tag |
+| Playwright E2E | Register → pay (sandbox) → ticket → scan → cashup; multi-day check-in; kiosk |
+| Job queue | Move `setInterval` jobs out of `index.js` into `pg-boss` (uses Postgres): retries, no double runs, job history in admin |
+| Split big controllers | `registrationController` (2.3k lines), `eventController`, `paymentController` → services by domain. Done **as each feature touches them**, not as a big-bang rewrite |
+| TypeScript backend | Incremental (`allowJs`), new code in TS first; share zod schemas/types with the frontend |
+| API v2 | `/api/v2` with consistent errors, pagination and an OpenAPI spec (replaces the hand-written API docs). `/api` (v1) kept during the transition |
+| Dependencies | Express 5, native `fetch` instead of `node-fetch`, password hashing upgrade with rehash-on-login |
+
+---
+
+## Suggested build order
+
+| Phase | Version | Features | Why |
+|-------|---------|----------|-----|
+| 0 | 1.32.0 ✅ | **Early-bird ribbon** on event cards (shipped 2026-10-22) | Quick win |
+| 1 | 1.33.0 ✅ | **Multi-day events — phase A** (sessions, whole-course tickets, late joining + late pricing, per-session check-in with whole-day window, attendance register, optional reminders, certificates) | Requested first; touches registration/tickets/scanning, so it shapes later work |
+| 2 | 1.34.0 ✅ | CI + Playwright E2E + job queue | Safety net before the riskiest work (payments). Session reminders move to the queue |
+| 3 | 1.35.0 ✅ | Multi-day events — phase B (pick sessions, per-session capacity) | Builds on phase A, now with E2E coverage |
+| 4 | 1.36.0 ✅ – 1.37.2 | Payment provider interface (Yoco moved behind it) → PayFast, then hiding "Pay online" when it can't be used and payment status checks (SnapScan and Zapper dropped) | Payment code gets split out of the big controller as part of this |
+| 5 | 1.38.0 – 1.39.0 | **POPIA toolkit** (user privacy centre + unsubscribe first, then admin tools, retention jobs, readiness page) | Main selling point; retention jobs use the job queue |
+| 6 | 1.40.0 + Hub v1 | Install/update scripts, `/health`, licence step in `/setup`, "Connect to Hub", heartbeat, licence states — plus the **Hub** app (separate repo) | Must exist before the first church is sold; Hope Family Church registers as install #1 |
+| 7 | 1.41.0 | **Multi-campus** | Kids rooms and volunteer roles are per campus, so campuses come first |
+| 8 | 1.42.0 – 1.43.0 | Kids check-in, Volunteer rosters | Depend on sessions and campuses |
+| 9 | 1.44.0 – 1.46.0 | Event series & cloning, Wallet passes, Outbound webhooks | Smaller, independent wins |
+| 10 | 1.47.0 – 1.49.0 | Admin dashboard/Ctrl+K/bulk actions, Afrikaans, Accessibility pass | Polish before the big release |
+| 11 | 1.50.0 | TypeScript backend + OpenAPI + `/api/v2` alongside v1 | The breaking-change groundwork |
+| 12 | **2.0.0** | v1 API removed, migration guide, marketing site/docs for selling | The release |
+
+Each phase should add matching help content (`frontend/src/content/help/`),
+audit log entries, Jest tests, a CHANGELOG entry, and updates to FEATURES.md
+and SETTINGS.md — same as the previous round. Branch → merge → tag → push per
+feature.
+
+---
+
+## Decisions (2026-10-22)
+
+| # | Question | Decision |
+|---|----------|----------|
+| 1 | Pick sessions in the first release? | No — whole-course first (1.33.0), pick sessions as a separate release (1.35.0) |
+| 2 | Late joining and late price | Set **per event**: late joining on/off (until session N), and the late price (full / pro-rata / fixed) |
+| 3 | Check-in window | Per event, **whole day** by default (any time on the session's date); "session time only" as the alternative |
+| 4 | Certificates | Yes — four templates (Classic, Modern, Church, Kids); the event creator chooses whether to issue certificates and which template |
+| 5 | Session reminders | Off by default, configurable per event |
+| 6 | Selling model | **One install per church** — data separation, any server. No multi-tenant. **Multi-campus** inside an install is in scope |
+| — | Pro-rata rounding | Nearest R10 |
+| — | Multi-campus | In scope (§12), inside one install |
+| — | Central management | **Hope Events Hub** in its **own git repo** (`joshua/hope-events-hub`): installs register on setup, send heartbeats (health, version, aggregate stats), licences switched on/off centrally |
+| 7 | Payment provider order | Yoco · PayFast. Joshua can supply documentation links |
+| — | SnapScan, Zapper | Dropped (2026-10-23): Yoco and PayFast are enough. Later versions moved up by two |
+| — | Provider fees | Not deducted or estimated automatically; handled by people during cashup. No "pass fee to payer" |
+| — | Minimum online payment | R15 for all providers |
+| — | Scope | All features in this document approved; POPIA toolkit and kids check-in are highlights |
+| — | Early-bird ribbon | Added before everything else; shipped as 1.32.0, all later versions moved up by one |
+
+## Still open
+
+Hub (needed before phase 6, not before 1.33.0):
+
+1. Hub domain and server, and where licence keys come from (created by hand
+   in the Hub per customer?).
+2. Grace period length (proposed 14 days) and suspended = read-only (tickets
+   still scan, data export still works) — agreed?
+3. Should payment totals be in the heartbeat at all (opt-in per customer), or
+   counts only?
+4. Licence plans/tiers (e.g. limits on campuses or WhatsApp), or one plan for
+   now?
