 ## [Unreleased]
 
+## [1.21.0] - 2026-10-19
+
+### Added
+
+- Post-event feedback, set up in a new Feedback step in the event wizard.
+  - Questions use the form builder.
+  - You pick when it's sent (the default is the morning after the event) and who gets it: everyone who checked in, or everyone registered.
+  - Each person gets a personal link by email (and WhatsApp where they use it).
+  - Anyone who hasn't answered gets one reminder 3 days later.
+  - Answers can be anonymous or named.
+  - "Send now" is available, and the questions lock once people start answering.
+- New form field types: **Rating (1–5 stars)** and **Multiple choice**. They're used for feedback, and can also go on attendee forms (registration page, My Events, the kiosk, manual registration and Supervisor → Forms).
+- New report, **Feedback summary**:
+  - response rate;
+  - average rating per question, with star distribution;
+  - multiple-choice and yes/no breakdowns as bar charts;
+  - a list of text answers (with names unless the form is anonymous).
+  - Select several events to compare their ratings (e.g. Camp 2025 vs Camp 2026). Exports to PDF and Excel like other reports.
+- New `/api/feedback` endpoints and a job every 15 minutes (`FEEDBACK_JOB_ENABLED=false` to turn it off).
+  - Requires the `add_feedback_forms` database migration.
+
+## [1.20.0] - 2026-10-19
+
+### Added
+
+- Sponsor a spot: a new event setting, "Allow sponsorships" (event wizard → Sponsor a spot).
+  - It adds a "Sponsor a spot" button on the event page so people can fund a place for someone who can't afford it.
+  - Sponsors choose one or more whole spots (at the main ticket price) or a custom amount, and pay through Yoco. Guests just give a name and email.
+  - Sponsors can give anonymously, or add a name and a message for the organisers.
+  - An optional goal ("12 of 20 spots sponsored") and public progress bar.
+- Each sponsorship is recorded as a donation tagged to the event, in that event's sponsorship pool.
+  - Supervisors assign pool money to registrations with the existing donation assign/unassign flow, fully or partly.
+  - Under Payments → Donations, sponsorships are labelled, there's an "Only the sponsorship pool" filter, and the sponsor's message is shown.
+  - Who receives help is never shown to sponsors.
+- Sponsors get a "Thank you for sponsoring a spot" receipt.
+  - Automations has a new "Thank Your Sponsors" email for events with sponsorships.
+  - Email attendees can target an event's sponsors (`filter.audience: 'sponsors'`).
+- The Donations breakdown report has sponsorship pool columns per event: received, assigned and remaining.
+- New `/api/sponsorships` endpoints.
+  - Requires the `add_sponsorships` database migration.
+
+## [1.19.0] - 2026-10-19
+
+### Added
+
+- Rooms & groups (Supervisor → Rooms & groups), for camps and lockdowns: put attendees into rooms, cabins, small groups, teams or buses.
+  - Each event can have several allocation sets (e.g. "Rooms" and "Buses"). Each set has groups with an optional capacity, an optional gender restriction and an optional leader (a staff member).
+  - A drag-and-drop board puts people not yet placed on the left and groups, with capacity counters, on the right. Full groups and groups for the other gender won't accept a person.
+  - Auto-allocate fills groups evenly with everyone not yet placed, respecting capacity and gender. It can keep people on the same booking together or spread them out.
+  - Printable lists per group (with leader) and a master list. On youth events they can include medical and emergency details from consent forms; viewing those is recorded in the audit log.
+  - "Show on tickets" prints the group on each person's ticket and shows it in My Events.
+  - Email and WhatsApp attendees can be sent to one group ("Bus 2 leaves at 07:30"). Messages go to whoever booked for the people in it.
+  - Group leaders see their people under Staff → My groups. Medical details are shown to supervisors only.
+- New event setting "Ask each person's gender" (under Named attendees). It adds a gender choice for each named person on the registration page, at the door, on the kiosk, in manual registration and in My Events, and is needed for gender-split rooms.
+- New `/api/allocations` endpoints.
+  - Requires the `add_room_allocation` database migration.
+
+## [1.18.0] - 2026-10-19
+
+### Added
+
+- Ticket transfer. On My Events, "Transfer" hands a ticket to someone else before the event: enter their name and email or phone.
+  - The new holder gets the ticket by email/WhatsApp with a new QR code. If they're new, an inactive account is created and they get an activation link.
+  - The old QR code stops working, so screenshots of it won't scan. Scanning it says who the ticket was transferred to, and offline-mode sync flags it.
+  - For a ticket covering several people, one place is split off to the new holder.
+  - The payer stays responsible for the registration.
+- Transfer rules:
+  - Only before the event starts, and only for tickets that haven't been scanned.
+  - It can be turned off per event (new "Ticket transfer" setting in the event wizard, on by default). Supervisors can always transfer, from At the door → Tickets.
+  - On youth events, the new holder's date of birth, and a parent's details for a minor, are needed, and a new consent request is sent.
+  - The previous holder's attendee form answers and consent medical details are removed.
+  - Every transfer is recorded in the audit log.
+- New endpoints `POST /api/tickets/:id/transfer` and `GET /api/tickets/:id/transfers`.
+  - Requires the `add_ticket_transfer` database migration.
+
+## [1.17.0] - 2026-10-19
+
+### Added
+
+- Offline ticket scanning. While online, staff pick an event and section on the scanner and tap "Enable offline mode". The section (or the whole event) is locked to their device and its tickets are downloaded to the device.
+  - With no connection, scans are checked against that list and queued on the device.
+  - The panel shows when the list was downloaded and how many scans are waiting.
+  - Queued scans sync automatically when the device is back online (or with "Sync now"), and check-in messages go out then.
+  - "Release section" ends offline mode and deletes the list from the device.
+- Only one device can hold a section at a time (a whole-event lock clashes with every section). While a section is locked, other devices see who holds it and can't scan it, online or offline, so a ticket can never be redeemed twice by two offline devices.
+- Syncing is idempotent and never redeems more than is left on a ticket. Anything that needs a person to look goes into a sync report: tickets not found, cancelled registrations, used-up tickets, scans outside the locked section, and check-ins without consent.
+- Supervisor → Offline scanning page: active locks with force release (for a lost or flat phone; its scans still sync if it reconnects, and are flagged), and sync reports to review. Locks, releases, force-releases and syncs are recorded in the audit log.
+- The scanner is installable as an app (web app manifest), and a service worker caches the scanner page and its scripts so it opens with no connection.
+- The app now stays signed in with the last confirmed profile when it's reloaded without a connection, instead of sending the user to the login page.
+- New `/api/scan-locks` endpoints.
+  - Requires the `add_offline_scanning` database migration.
+
+### Changed
+
+- `POST /api/tickets/scan/:qrCode` now accepts `sectionId` and checks it on the server; this was previously only checked in the browser.
+  - It now refuses (423) scans in a section that another device has locked for offline scanning.
+
+## [1.16.0] - 2026-10-19
+
+### Added
+
+- Waitlist for sold-out tickets. A new event setting (event wizard → Visibility) turns it on, with how long offered places are held (24 hours by default) and whether someone can be offered fewer places than they asked for.
+  - Sold-out tickets show "Join waitlist" on the event page, the register page and the events list. Guests can join on events that allow guest registration.
+- When places free up, the next person is emailed/WhatsApped a claim link, and the places are held for them so nobody else can buy them. Places free up through a cancellation (by the person or staff), a smaller booking, or a raised stock limit.
+  - The claim link opens the register page with the places pre-selected, and works without logging in.
+  - Unclaimed offers expire (checked every 10 minutes) and move on to the next person.
+- People can leave a waitlist from My Events, which now lists their waitlists and any places held for them.
+- Supervisor → Waitlist page: the queue per event, with offer now (even over the stock limit), move up/down and remove.
+- The daily summary email shows each event's waitlist count.
+- New `/api/waitlist` endpoints. `POST /api/registrations` accepts `waitlistToken`.
+  - Requires the `add_waitlist` database migration.
+
+### Fixed
+
+- Manual registrations (Manual registration, At the door, the kiosk) and adding places to an existing booking never checked stock, so either could take an option over its stock limit. Both are now checked like a normal registration.
+- Stock is now counted in one place (`utils/stock.js`) for registration checks, `availableCount` and `isSoldOut`, including places held for waitlist offers.
+
+## [1.15.0] - 2026-10-19
+
+### Added
+
+- Parental consent for youth events. A new "Requires parental consent" event setting (event wizard → Visibility) has its own consent text and optional medical info, emergency contact and photo consent questions. It turns on named attendees automatically.
+  - Registering then needs a name and date of birth for every main-ticket place. Anyone under 18 on the event's start date needs a parent or guardian's name, email and phone.
+  - This applies on the registration page, manual registration, at the door, the kiosk, and when editing names in My Events.
+- The parent gets an email and a WhatsApp (always both) with a link to a new consent page (`/consent/<token>`). There they read the text, answer the optional questions, type their full name and confirm they're the parent or guardian, then give or decline.
+  - The system records the time, IP, device, signed name, and the exact consent text and version shown.
+  - Medical and emergency details are stored encrypted.
+  - The registrant and the event's notification recipients are told the outcome.
+- Tickets are still issued, but the scanner blocks check-in until consent is given, showing why. Supervisors can override, and the override is recorded in the audit log. On a youth event, a ticket with no named attendee counts as missing consent.
+- A daily 09:00 job reminds unanswered requests after 2 days, then every 3 days until the event. It also deletes medical and emergency details a set number of days after the event (Site Settings → Legal, default 30). `CONSENT_JOBS_ENABLED=false` turns it off.
+- Supervisor → Parental consent page: consent status per attendee, resend one or all pending requests, re-request consent after the consent text changes, and a printable, confidential medical & emergency list. Every view of the list is recorded in the audit log.
+- New reports: "Parental consent status" and "Medical & emergency list".
+- My Events shows each attendee's consent status, with a "Resend consent" button.
+- Anonymising or closing an account also clears that person's attendees' parent, date-of-birth, medical and emergency details.
+- New endpoints under `/api/consent`. `GET /api/tickets/scan-preview/:qrCode` now returns `consentStatus`, and `POST /api/tickets/scan/:qrCode` accepts `overrideConsent`.
+  - Requires the `add_parental_consent` database migration.
+
+## [1.14.0] - 2026-10-19
+
+### Added
+
+- Group tickets (named attendees). A new "Named attendees" event setting (event wizard → Visibility) lets someone registering several people give each main-ticket place a name, with an optional email and phone. It's offered on the registration page, Manual registration, At the door and the self-service kiosk.
+  - Each named person gets their own single-person ticket, with their name on the ticket PDF, the scanner's confirm screen and the staff ticket list. Places left unnamed share one quantity ticket as before.
+  - The payer chooses whether every ticket comes to them or each person gets their own by email/WhatsApp; anyone without contact details falls back to the payer.
+  - The payer stays the account owner for billing, invoices and payments.
+  - An attendee whose email or phone matches an existing account is linked to it (never when the email and phone belong to two different accounts). Their ticket then appears in their own My Events, marked "Booked by …", and they can open and submit their own attendee form.
+- My Events → registration popup has a new "People" section for adding or changing names and contact details, switching ticket delivery, and sending an attendee a link to fill in their own form (`/forms?registrationId=…&attendeeId=…`). An attendee whose ticket has been scanned can't be removed.
+- Attendee forms now show one block per named person, labelled with their name, and each response is saved against that attendee.
+- New endpoints `PUT /api/registrations/:id/attendees` and `POST /api/registrations/:id/attendees/:attendeeId/send-form-link`. `POST /api/registrations` and `/manual` accept `attendees` and `ticketDelivery`.
+  - Requires the `add_named_attendees` database migration.
+
+### Changed
+
+- Reducing the quantity of a main ticket removes the newest names beyond the new quantity.
+- Check-in confirmations for a named ticket go to that person when the registration sends each person their own tickets.
+- Unauthenticated guest registration now matches an existing account by phone as well as email, and is refused (409) when the email and phone belong to two different accounts, instead of silently reusing whichever account the email matched.
+- Free registrations now issue tickets through the same generator as paid ones, instead of a separate copy of the logic.
+
+### Security
+
+- Registration details (`GET /api/registrations/:id`) hide attendees' email addresses and phone numbers from anyone other than the payer and staff, such as an attendee opening their form link.
+
+## [1.13.0] - 2026-10-19
+
+### Added
+
+- Coupon codes. Supervisors create percentage, fixed-amount or free ("comp") codes under Supervisor → Coupon codes.
+  - Codes can be limited to particular events, ticket options or variants, a date window, total and per-person uses (one per person by default), a minimum number of tickets, and specific people, roles (e.g. Staff and above) or an email domain. Restricted codes need a logged-in account, so they can't be shared around.
+  - By default the better of the code and the early-bird price wins; a code can instead stack on top of early-bird pricing.
+  - People enter codes under "Have a code?" on the registration page and in My Events (for registrations not yet paid in full). Staff can apply them in Manual registration, At the door and the self-service kiosk.
+  - The discount is locked in when it's applied, the same way early-bird prices are. It appears as its own line on invoices, receipts, registration and payment emails, WhatsApp messages and the Yoco checkout.
+  - Editing a registration's items recalculates percentage and free codes; fixed-amount codes keep their amount. Cancelling a registration frees the use. A free code that covers everything marks the registration paid and sends the tickets.
+  - Use limits are enforced under a database lock, so the last available use can't be claimed twice.
+- Staff price: a ticket option or variant can carry a staff price (event wizard → Items & pricing) that Staff and above pay automatically when it's lower than the normal price.
+- New "Discounts (coupon codes)" report (Reports → Financial), showing uses and value given away per code and event. The Finance report's "What was sold" is now shown after discounts.
+- Coupon activity in the admin audit log: codes created, edited and turned off, and codes applied or removed by staff.
+- New endpoints: `POST /api/coupons/validate`, `GET|POST /api/coupons`, `GET|PUT /api/coupons/:id`, `GET /api/coupons/redemptions`, `POST|DELETE /api/registrations/:id/coupon`. `POST /api/registrations` and `/manual` accept `couponCode`.
+  - Registration responses now include `discountTotal` and `subtotalComputed`.
+  - Requires the `add_coupon_codes` database migration (`npm run prisma:deploy` in `backend`).
+
+### Fixed
+
+- Yoco checkout line items priced each item at its most recent price times the whole quantity. When a line spanned several price tranches (some tickets at early-bird, some at full price), the item lines didn't match the amount charged. They now list each price actually charged.
+- The free-registration check on `POST /api/registrations` and `/manual` had the same fault: it used the latest price for the whole quantity instead of the real total.
+
+## [1.12.0] - 2026-10-19
+
+### Added
+
+- Two-factor authentication is now required for Admin and Supervisor accounts. An admin or supervisor without it is sent a code at their next login (by email, or WhatsApp when SMTP isn't set up), and entering it turns two-factor on — the same code step as before, with a note explaining why. Trusted devices don't skip this first code. They can change whether codes come by email or WhatsApp from Profile & Security, but can no longer turn two-factor off (`POST /api/users/2fa/disable` returns 403 for them).
+- Existing admin and supervisor sessions without two-factor are ended on their next request (`401` with `code: "TWO_FACTOR_REQUIRED"`), and the login page explains why. Promoting a user to supervisor or admin also ends their sessions if they don't have two-factor yet, so they enrol at their next login. An admin "Reset 2FA" for a supervisor/admin now means they set it up again at their next login.
+- The requirement is skipped when no channel can deliver a code — no SMTP configured and no WhatsApp — so a fresh install (or the setup wizard, which also gets a short grace period) never locks the first admin out. `TWO_FACTOR_REQUIRED_ROLES=false` turns the requirement off as an emergency switch.
+
+- `FEATURES.md`, a repo-root overview of everything the platform does — roles, public site, events, registration, payments, tickets, messaging, dashboards, cashup, reports, settings, security, background jobs, and a page map.
+
+### Changed
+
+- `info.md` (the overview for prospective churches) brought up to date with features added since it was written — donations, invoices and receipts, cashup and costs, profit reporting, audit trail, scheduled messaging, self-service kiosk, scan points, backups, branding, and privacy controls.
+
+## [1.11.0] - 2026-10-08
+
+### Added
+
+- Optional two-factor authentication. Any user can turn it on from Profile & Security and choose to receive a 6-digit code by email or WhatsApp; the chosen channel is confirmed with a code before it takes effect. At login the code is asked for after the password, expires after 10 minutes and allows 5 attempts, with a "Resend code" option. If a WhatsApp code can't be sent, it falls back to the account's email address.
+- "Trust this device for 30 days" on the code step, so a remembered device skips the code. Trusted devices are forgotten when the password is changed or reset, when sessions are signed out everywhere, and when two-factor is turned off.
+- Admins can reset two-factor authentication for a user who can no longer receive codes ("Reset 2FA" on the Users page). Turning two-factor on or off shows in Account activity.
+- The self-service kiosk asks supervisors with two-factor on for their code at setup. Changing the event now re-confirms the password against the existing kiosk session (`POST /api/users/verify-password`) instead of logging in again.
+
+### Changed
+
+- `POST /api/users/login` returns `{ twoFactorRequired, challengeId, method, destination }` instead of a token for accounts with two-factor on; the token is issued by the new `POST /api/users/login/2fa`. Accounts without two-factor are unaffected. Requires the `add_two_factor` database migration (`npm run prisma:deploy` in `backend`).
+
+## [1.10.6] - 2026-10-08
+
+### Fixed
+
+- The frontend production build (`next build`) no longer hangs or fails when the backend isn't reachable. With no `NEXT_PUBLIC_API_URL`/`API_URL` set, the root layout fetched a relative `/api/settings` URL that never settled during prerender, so every page timed out after 60 seconds; server-side fetches now fail fast when no API base is configured. The home page and the Events page also no longer fail the build when `/api/events` can't be reached — they build with an empty list and fill in on the first revalidation. At runtime a failed fetch still errors, so the last good page keeps being served.
+
+### Security
+
+- Updated dependencies to clear `npm audit` advisories: `express`, `multer`, `proxy-addr`, `qs` and others in the backend, `next` (15.5.27) and `sharp` (0.35.5) in the frontend, and `nodemailer` from 9 to 10 (requires Node.js 20 or newer). The root package now overrides `shell-quote` to a patched release, since every `concurrently` version pins a vulnerable one. Backend production dependencies now report no known vulnerabilities; the remaining advisories are in development tooling (`nodemon`, `jest`, `tailwindcss` 3) and have no non-breaking fix.
+- Dependency install scripts are now explicitly allow-listed via `allowScripts` in the backend and frontend `package.json` (Prisma, `@sentry/cli`, `unrs-resolver`), so npm no longer blocks them.
+
+## [1.10.5] - 2026-10-01
+
+### Fixed
+
+- Events that have already started but not yet finished now show on the home page and the Events page. Both pages were hiding an event as soon as its start time passed; they now keep it listed until its end time, which matches what `GET /api/events` already returns.
+
+## [1.10.4] - 2026-09-01
+
+### Fixed
+
+- "Add to calendar" (`GET /api/events/:id/ics`) always failed with a 400 in production: the `ics` library's `url` field requires a scheme (`https://...`), but `FRONTEND_URL`/`APP_BASE_URL` was configured without one, so `createEvent()` rejected it before generating any output. A missing scheme is now assumed to be `https://` instead of failing.
+
+## [1.10.3] - 2026-08-28
+
+### Fixed
+
+- Creating an event was never recorded in the admin audit log — 1.10.0 added `event_created` as a logged action on the frontend's filter list, but the backend's `createEvent` never actually called `logAdminAction`, only `updateEvent`/`deleteEvent` did. Event creation is now logged the same way.
+- Staff cancelling a registration via `PUT /api/registrations/:id` (the staff status-change endpoint, separate from the owner-facing `DELETE /:id` cancel route) wasn't logged at all — only the `DELETE` path logged `registration_cancelled`. Both paths now log it, verified against all six audit categories promised in 1.10.0 (refunds, donation assign/unassign, manual registrations, staff-initiated cancellations, event create/update/delete, settings changes) with no other gaps found.
+- Added a "Back to dashboard" link to Admin → Audit log, matching the back-link pattern already used on the Cashup page.
+
+## [1.10.2] - 2026-08-28
+
+### Fixed
+
+- Sentry wasn't instrumenting Express (`[Sentry] express is not instrumented` at startup): `express`, `cors`, and `@prisma/client` were required at the top of `backend/src/index.js` before `Sentry.init()` ran, but Sentry's auto-instrumentation patches those modules via a require hook that only works if `Sentry.init()` runs first. `Sentry.init()` now runs immediately after `dotenv.config()`, before any of the libraries it instruments are required.
+
+## [1.10.1] - 2026-08-28
+
+### Security
+
+- Fixed a path-traversal vulnerability in event-image, branding (logo/favicon), and event-attachment uploads: the stored filename embedded the client-supplied `originalname` unsanitized, so a crafted filename (e.g. containing `../`) could write the uploaded file outside the intended `public/uploads` subfolder anywhere the server process could write. Uploaded files are now always saved under a server-generated random name; the original filename is preserved only as display metadata.
+- `express-rate-limit` was declared as a root-only dependency despite being required directly by the backend (`backend/src/index.js`) — a plain `cd backend && npm install`, as documented in the deployment guide, would not have installed it. It's now a proper `backend/package.json` dependency.
+- Bumped `next` (frontend) off a version affected by a critical unauthenticated RCE in the React Flight protocol (GHSA-9qr9-h5gf-34mp) and several other CVEs, and switched it from an exact pin to `^15.5.24` so future patch releases install automatically.
+- Bumped `multer`, `nodemailer`, `jsonwebtoken`, and `uuid` (backend) to versions fixing DoS, SMTP/CRLF-injection, HMAC-verification, and buffer-bounds advisories; added an `overrides` entry so the vulnerable `uuid` nested under `exceljs` is also patched. Ran `npm audit fix` across all three workspaces (root/backend/frontend) — 0 known vulnerabilities remain.
+- `jwt.verify()` now pins `algorithms: ['HS256']` explicitly rather than trusting the algorithm from the token header.
+- Uploaded assets served from `/uploads` now get `Content-Security-Policy: default-src 'none'; sandbox` and `X-Content-Type-Options: nosniff`, so an uploaded SVG containing a `<script>` can no longer execute if opened directly.
+
+## [1.10.0] - 2026-08-28
+
+### Added
+
+- Event detail pages now have an "Add to calendar" button, and registration confirmation emails include an "Add to calendar" link (requires `BACKEND_URL` to be set), both downloading a `.ics` file for the event.
+- SEO: the site now serves a `sitemap.xml` (every public page plus every event) and `robots.txt`, and event/event-list pages have proper Open Graph/Twitter metadata for link previews.
+- Error monitoring via Sentry — set `SENTRY_DSN` (backend) and `NEXT_PUBLIC_SENTRY_DSN` (frontend) to enable; a no-op otherwise. Captures unhandled backend errors/promise rejections and frontend errors.
+- Nightly local database backups (`pg_dump`, gzipped, 02:00, 14-day retention by default) with a new Site Settings → Backups tab to view, manually trigger, and download them. Requires `pg_dump` to be installed on the app server; set `BACKUP_ENABLED=false` to disable. Local-disk only — not uploaded anywhere else.
+- Admin audit trail: refunds, donation assign/unassign, manual registrations, staff-initiated cancellations, event create/update/delete, and settings changes are now logged with who/when/what, viewable at Admin → Audit log.
+- Starter backend test suite (Jest) covering the early-bird tranche pricing logic and donation-balance calculation — the two areas with the most complex money-handling history in this changelog.
+
+## [1.9.5] - 2026-08-27
+
+### Fixed
+
+- The public event-alias route (`/:redirectUrl`, used for short links like `/camp-2025`) is a catch-all matching any unmatched top-level path, so every bot/scanner probe for a nonexistent page (`/wp-login.php`, `/.env`, etc.) was hitting the backend and firing a live database query. Both the frontend route and the `GET /api/events/by-alias/:redirectUrl` endpoint now reject anything that isn't a plausible alias (letters/numbers/hyphens/underscores) before touching the database, instead of forwarding scanner noise straight through — this traffic pattern could exhaust the database connection pool and take the server down under load.
+
+### Added
+
+- PM2 (`ecosystem.config.js`) now restarts either process if it exceeds 500MB of memory, instead of letting an unbounded leak run until the OS OOM-kills it.
+
+## [1.9.4] - 2026-08-26
+
+### Added
+
+- New `TRUST_PROXY` backend env var — set it when the app runs behind a reverse proxy (e.g. nginx on a separate server) so rate limiting reads the real client IP from `X-Forwarded-For` instead of the proxy's. Accepts a hop count, `true`/`false`, or trusted proxy IP(s)/CIDR(s).
+
+## [1.9.3] - 2026-08-26
+
+### Fixed
+
+- The server used to hard-crash (`process.exit(1)`) on any unhandled promise rejection, so a single missed error handler anywhere in the app's fire-and-forget notification code (email/WhatsApp sending) could take the whole server down. It now logs the error and keeps running.
+- Accounts created on someone's behalf (at-the-door walk-in registration, or manual registration from the Admin/Supervisor dashboard) now get their activation link (email or WhatsApp, whichever they have) sent immediately when the account is created, instead of only on their first failed login attempt — matching what the Terms of Use already promised.
+- Manual registration with a real email address used to create the account already active with a fixed, undisclosed password (`Hope123`) — the visitor had no way to know it. That account is now created inactive and gets the same immediate activation link, so the visitor sets their own password — unless a password was supplied directly (see below), in which case it's activated immediately with no link needed.
+- The self-service kiosk's "Create an account" password field never actually worked — the account was always created with a different password behind the scenes, so visitors who set one couldn't log in with it. Manual registration now honours a caller-supplied password and activates the account immediately instead of discarding it.
+- Removed the "Guest (no account)" checkboxes from the Manual Registration pages (both the current one and the legacy form) and the equivalent flag from the at-the-door kiosk — they stopped affecting backend behaviour once every walk-in account started being created inactive with an activation link. The self-service kiosk's own "Create an account" toggle still controls whether that link is sent, since that one is the visitor's own choice rather than staff acting on their behalf.
+
+## [1.9.2] - 2026-08-22
+
+### Fixed
+
+- Contact-only events (no registration possible) were still getting the daily summary email — it now skips them since there's nothing to summarize.
+
+## [1.9.1] - 2026-08-22
+
+### Fixed
+
+- The browser tab title and homepage "Welcome to..." heading always showed the app's built-in default name instead of the organisation name configured in Site Settings → Organisation.
+- The backend's status page (`/`) and API docs page (`/docs`) always showed "Cross Code Events" instead of the configured organisation name.
+
+## [1.9.0] - 2026-08-21
+
+### Added
+
+- Events now have an optional Location field (address), defaulting to the organisation's configured address when creating a new event. Wherever an address is shown — event admin form, public event page, event card listings, the Contact page, and Site Settings → Organisation — there's now a "Directions"/"View on map" link, and the event detail and Contact pages also show an embedded Google Maps view (no API key required).
+
+## [1.8.0] - 2026-08-21
+
+### Added
+
+- Events can now be marked "contact-only" (e.g. baptism) — they appear on the public events list/detail pages with a "Contact us" button (opening a popup with name/phone/email) instead of a Register button, and have no ticket options or registration flow. Configurable from a new toggle in the admin event wizard's Basic Details step.
+- Registration and payment notifications now include a branded PDF: registration confirmations attach an **invoice** (itemized breakdown, early-bird discount, balance due, and — when there's an outstanding balance — a clickable "pay now" link and QR code pointing at a Yoco checkout) whenever the registration isn't fully paid, and payment/donation confirmations attach a **payment receipt** (itemized breakdown plus the amount paid on that transaction). Sent as an email attachment and, over WhatsApp, as the PDF itself (with the existing message text as its caption) in place of the previous text-only send. Both documents pick up the org's configured name/logo/brand color from Site Settings → Branding.
+- The user dashboard's registration detail popup now has an "Invoice" button and, next to each payment, a "Receipt" button — both pop up a small Email/WhatsApp choice and (re)send that document on demand, via two new endpoints (`POST /api/registrations/:id/send-invoice`, `POST /api/payments/:id/send-receipt`), restricted to the registration/payment's own owner. The invoice works regardless of balance, showing "Paid in full" when nothing is owed. The Payment history page (`/dashboard/user/payments`) got the same per-payment "Receipt" button too.
+
+### Fixed
+
+- The user dashboard's "(early bird)" label was a price-comparison heuristic — it fired on any line priced below the option's base price, including plain cheaper variants that were never actually early-bird tickets. It now checks the real applied-tier flag the backend already tracks.
+- Buying more of an already-purchased ticket type after its early-bird tier expired re-priced the *entire* line at the new price instead of adding the new quantity at the new price (e.g. 5 tickets @ R50 + 1 more after the price rose to R100 came out to R600 instead of R350). Each purchase now gets its own price "tranche" recorded against the registration line, so previously-bought tickets keep their original price and only the newly added quantity uses the current price. Registration/reporting pages that showed a single blended price per line now render (or total) each tranche separately.
+- An unpaid (or partially paid) registration's price only ever got refreshed when a payment was actually attempted — an early-bird tier that expired while tickets sat unpaid kept showing its old, no-longer-honoured price (and its "(early bird)" tag) indefinitely on the dashboard until the user tried to pay. Viewing a registration (dashboard, registration detail, or an event's registration list) now refreshes still-outstanding pricing on the spot, same as payment already did.
+- The user dashboard's registration detail popup listed one line per price tranche in raw creation order, so a ticket bought across several separate registrations (e.g. some early-bird, some not) showed as a wall of near-duplicate lines. It now merges tranches with the same item/price/tier into one line and groups early-bird lines together, separately from standard-price lines.
+- Registration confirmation, payment/donation, and reminder emails and WhatsApp messages computed "Total due"/"Balance" by loading a registration without its price tranches, so any line spanning more than one tranche (e.g. some tickets bought at the early-bird price, more added later at full price) fell back to charging the *entire* quantity at the most recent tranche's price — silently wiping out the early-bird discount from the outstanding balance shown to the user. These sends now load tranches and total each line the same tranche-aware way the dashboard already did; the itemized line amounts in those messages (which previously always showed the option's undiscounted base price) are now correct too.
+- Editing an event option's early-bird tiers (even just tweaking one tier's deadline or price) deleted and recreated *every* tier for that option with brand-new ids, including tiers the admin didn't touch. Since past purchases point at a specific tier by id, this silently severed that link on every edit — wiping the "early bird" attribution (and locked-in stock-limit counts, risking oversold tiers) off historical registrations that were never meant to change. Tiers are now upserted by id, so their identity — and everything referencing them — survives an edit; a tier is only ever removed if it's no longer in the saved list *and* has no purchase history against it.
+
+## [1.7.0] - 2026-08-20
+
+### Added
+
+- Site Settings → Branding now supports a full Primary/Secondary/Accent brand color system (previously a single accent color that only recolored the org name in the navbar) applied site-wide — buttons, nav highlights, hover states, and links — plus a favicon upload alongside the existing logo upload, and a live preview panel (with website/email and desktop/mobile views) that updates as colors are picked, before saving. Selecting a logo now also suggests brand colors extracted from it. Outgoing emails' header and call-to-action buttons now pick up the Primary color too, while semantic alert colors (success/warning/danger) stay fixed. The setup wizard's Branding step got the same preview and color-suggestion treatment.
+
+### Fixed
+
+- The setup wizard's logo/favicon upload was silently failing — by the time it ran, the admin account already existed and the upload endpoint required admin auth, but the request never attached the token. It now does, and a failed upload surfaces as a visible error instead of quietly leaving branding unset.
+- A custom favicon saved via Site Settings never actually showed in the browser tab: the site had a static `favicon.ico` in the special Next.js `app/` convention path, which generates its own `<link rel="icon">` tag that always took priority over the admin's saved one. Moved the static file to `public/` so it's just the default fallback, not a competing tag.
+- Every unconfigured-organisation default across the app (org name, email subjects, WhatsApp messages, report file metadata, backend status/API-docs pages, `From:` fallback address) said "Hope Events"/"Hope Family Church" instead of a neutral placeholder — now defaults to "Cross Code" (the platform vendor) consistently. Several email subject lines (login/welcome/activation/password-changed/account-closed) were also fully hardcoded regardless of the configured org name; they now interpolate it dynamically like the email body already did.
+- The optional legal settings (operator name, Information Officer name/email, website URL, effective date, and the Legal pages' own email fallback) defaulted to this project's real founder's name/email/church details — actively misleading if ever shown on another organisation's deployed site before they're configured. These now default to obviously-generic placeholders (e.g. `example.com`, `[not yet configured]`) instead.
+- Added `SETTINGS.md`, a repo-root reference documenting every setting's default behaviour when left unconfigured.
+
+## [1.6.0] - 2026-08-08
+
+### Added
+
+- Supervisors can now unassign a donation that was previously applied to a registration, from a new "Assigned donations" list on the Payments page. This reverses the allocation (the registration's balance goes back up and the donation becomes available again), reverting the registration's status and revoking any tickets issued only because that allocation completed payment — blocked if a ticket has already been scanned. The registrant is notified by email/WhatsApp, mirroring the notification sent when a donation is first applied. The list can be searched (registrant, donor, or event) and filtered by event.
+
+### Fixed
+
+- The internal admin notification for a donation applied to a registration read "Payment recorded" / "Registration payment", indistinguishable from a real incoming payment even though no new money changed hands — it now says "Donation applied" throughout, matching the registrant-facing email's distinct wording.
+
+### Performance
+
+- Reconciling a Yoco card payment or sending a payment link on the supervisor Payments page no longer blocks the response on ticket-PDF generation and email/WhatsApp sends — these now run in the background, matching how manual payments already worked.
+- Registration creation and payment capture now resolve per-option pricing, stock checks, and ticket generation concurrently instead of one option at a time.
+- The supervisor Payments page no longer fires one request per registration to compute outstanding balances (that data was already included in the registrations response); post-action refreshes also run in parallel instead of sequentially.
+- Added indexes for `Registration(createdAt, status)`, `Ticket(createdAt)`, and `Payment(originalPaymentId, isDonation)` to speed up dashboard stats and donation-leg lookups. `GET /api/registrations` now supports optional `page`/`limit` pagination.

+## Roles
+
+Four roles, each including everything the roles below it can do:
+
+| Role | Can do |
+|------|--------|
+| **User** | Browse events, register, pay, donate, view tickets, fill in forms, manage their own profile |
+| **Staff** | Scan tickets, view/print event tickets, view registrations and form responses |
+| **Supervisor** | Create and manage events, record payments/refunds, assign donations, at-the-door desk, manual registration, bulk email/WhatsApp, reports, site banner, self-service kiosk |
+| **Admin** | Manage users and roles, all registrations, event costs and cashup (close/reopen events), audit log, site settings, WhatsApp connection, backups |
+
+---
+
+## Public site
+
+- **Home page** — hero section with the organisation's name and branding, upcoming
+  and in-progress events, and a "Join Us" button (becomes "My Dashboard" when
+  logged in).
+- **Events list** (`/events`) — event cards with picture, dates, location,
+  price, and a Register / Sold Out / Contact us button.
+- **Event detail** (`/events/[id]`) — description, ticket options with
+  variant and early-bird pricing, low-stock and sold-out badges, downloadable
+  attachments, embedded Google Map with "Directions" link, and an
+  **Add to calendar** (`.ics`) button.
+- **Short links** — events can have an alias (e.g. `/camp-2025`) that redirects
+  to the event. Only plausible aliases hit the database, so bot probes are
+  rejected cheaply.
+- **Contact page** (`/contact`) — organisation email, phone, address and map.
+- **Legal pages** — Terms of Use and Privacy Policy, filled from Site Settings.
+- **Site banner** — a site-wide announcement bar set by supervisors.
+- **Lockdown rules** (`/lockdown-rules`) — static rules page for the youth
+  lockdown event.
+- **SEO** — `sitemap.xml` (every public page and event), `robots.txt`, and
+  Open Graph/Twitter link-preview metadata.
+- **Theming** — brand colours, logo and favicon come from Site Settings.
+
+---
+
+## Events
+
+Created and edited by supervisors through a 6-step wizard: **Basic Details →
+Items & Pricing → Sections → Form → Visibility → Attachments**.
+
+- **Basic details** — title, description, start/end dates, registration
+  deadline, picture (upload or URL), location (defaults to the org's address),
+  contact person.
+- **Contact-only events** — for things like baptisms: shown publicly with a
+  "Contact us" popup instead of registration, with no tickets.
+- **Ticket options** — multiple options per event (e.g. Adult, Child, Dinner,
+  T-shirt), each with a price and optional **stock limit**. One option is marked
+  as the main ticket, which is what gets checked in at the door.
+- **Variants** — sub-types of an option (sizes, colours, Adult/Child/VIP), each
+  with an optional price override and its own stock limit.
+- **Early-bird tiers** — deadline- and/or stock-limited cheaper prices per
+  option or variant. Prices are locked in per purchase ("tranches"), so buying
+  more later doesn't re-price what was already bought.
+- **Sections** — named scan points (e.g. "Main hall", "Dinner") limited to
+  certain ticket options, so a scanner at that point only accepts those tickets.
+- **Visibility** — active/inactive, hidden (reachable only by link), scheduled
+  go-live date, require login vs. allow guest registration, or no registration
+  at all.
+- **Attachments** — downloadable files (maps, schedules, waivers) shown on the
+  event page.
+- **Notify recipients** — choose which staff get registration/payment alerts and
+  the daily summary for the event.
+- **Sold-out handling** — an event is sold out when every stock-limited option
+  is exhausted. "X remaining" badges appear at a threshold that scales with
+  capacity.
+
+---
+
+## Registration
+
+- **Online registration** (`/register/[eventId]`) — pick options, variants and
+  quantities; see early-bird prices and stock warnings; fill in the event form.
+- **Guest registration** — when an event doesn't require login, an inactive
+  account is created and an activation link is sent by email or WhatsApp.
+- **Statuses** — Pending, Confirmed, Partially Paid, Paid, Cancelled.
+- **Edit options** — users can add or change items on their registration
+  (not for past or closed events).
+- **Self-cancellation** — allowed only before any payment; admins can cancel
+  any time.
+- **Pricing refresh** — when an unpaid registration is viewed or paid, expired
+  early-bird prices are re-evaluated, and the user is warned if the total
+  changed.
+- **Manual registration** (supervisor) — register someone on their behalf,
+  creating an account if needed. Includes a "Record Payment" tab.
+- **Duplicate-account protection** — if an email and phone belong to two
+  different accounts, the registration is blocked instead of merging them.
+- **Group tickets** — on events with "Named attendees" turned on, someone booking
+  several places can name each person (with optional email/phone). Each named person
+  gets their own ticket and their own attendee form; unnamed places share one ticket.
+  Tickets go all to the payer, or each to the person (falling back to the payer).
+  Attendees matching an existing account see their ticket in My Events. Names can be
+  added or changed later from My Events, and attendees can be sent a link to fill in
+  their own form. Available on the registration page, manual registration, At the
+  door and the kiosk.
+- **Waitlist** — on events with a waitlist, sold-out tickets show "Join waitlist"
+  (on the event page, the register page and the event list). When places free up — a
+  cancellation, a smaller booking or a higher stock limit — the next person is
+  emailed/WhatsApped a claim link and the places are held for them (24 hours by
+  default) so nobody else can buy them. Unclaimed offers expire and move on; people
+  who asked for more than came free can be offered what's free or skipped. Claiming
+  works without logging in. People can leave from My Events.
+- **Parental consent (youth events)** — on events that require it, every attendee
+  gives a date of birth; for anyone under 18, a parent or guardian gets an email and
+  a WhatsApp with a consent link. They read the event's consent text, optionally give
+  medical info, an emergency contact and photo consent, type their name to sign, and
+  give or decline. Tickets are issued but can't be checked in until consent is given
+  (supervisors can override, audited). Reminders go after 2 days, then every 3 days.
+  Medical details are encrypted and deleted a set number of days after the event.
+- **Coupon codes** — percentage, fixed-amount or free (comp) codes, entered under
+  "Have a code?" on the registration page, in My Events (for unpaid registrations),
+  manual registration, At the door and the kiosk. Codes can be limited to events,
+  ticket options or variants, dates, total and per-person uses, a minimum quantity,
+  and specific people, roles or an email domain (restricted codes need a login).
+  Early-bird prices either stack or the better price wins. The discount is locked in
+  when applied and shows on invoices, receipts, emails and the Yoco checkout;
+  cancelling frees the use. Managed from Supervisor → Coupon codes.
+- **Staff price** — a ticket option or variant can have a staff price that Staff and
+  above get automatically, without a code.
+
+---
+
+## Payments, donations & refunds
+
+- **Online card payments via Yoco** — checkout for the full outstanding balance,
+  confirmed by a signed webhook.
+- **Payment links** — supervisors can generate and send a Yoco link for any
+  amount (including partial).
+- **Manual payments** — cash, card, EFT, voucher or other, recorded by staff.
+  Each payment records **who recorded it** as well as who it's for.
+- **Refunds** — negative payments against an original payment, netted against
+  the original method.
+- **Post-event feedback** — a Feedback step in the event wizard.
+  - Questions use the form builder, with new **star rating (1–5)** and **multiple
+    choice** types (also available on attendee forms).
+  - The form goes out at a chosen time to everyone who checked in, or to everyone
+    registered, each with a personal link (`/feedback/<token>`). One reminder goes
+    3 days later to anyone who hasn't answered.
+  - Answers can be anonymous or named. "Send now" is available, and the questions
+    lock once people have answered.
+- **Sponsor a spot** — per-event setting. A "Sponsor a spot" button on the event page
+  lets anyone, including guests, pay for one or more spots (at the main ticket price)
+  or any amount through Yoco. They can give anonymously or add a name and a message.
+  The money is a donation tagged to the event and goes into its sponsorship pool, which
+  supervisors assign to registrations with the usual donation flow.
+  - An optional public progress bar ("12 of 20 spots sponsored") with an optional goal.
+  - Sponsors get a thank-you receipt, and an Automations thank-you can go to all of an
+    event's sponsors.
+  - The Donations breakdown report shows each pool: received, assigned and remaining.
+  - Who is helped is never shown.
+- **Donations** — users can donate from their dashboard (`/dashboard/user/donate`).
+  Supervisors can **assign** a donation (fully or partly) to someone's
+  registration and **unassign** it later. Assignments are kept as separate
+  records, so the original donation never changes.
+- **Yoco reconciliation** — imported Yoco transactions can be matched to a
+  registration, recorded as a donation (optionally choosing the donor), or
+  ignored.
+- **Invoices & receipts** — branded PDFs: an invoice (itemised, early-bird
+  discount, balance due, pay-now link and QR code) and a payment receipt. Sent
+  automatically and re-sendable on demand by email or WhatsApp.
+- **Method normalisation** — Apple Pay / Google Pay / checkout payments count as
+  "Card" in reports and user views.
+
+---
+
+## Tickets & check-in
+
+- **Automatic tickets** — QR-coded tickets are generated when a registration is
+  fully paid (or free), and sent as a PDF by email and/or WhatsApp.
+- **Quantity tickets** — one ticket can cover several people and be redeemed
+  partially (e.g. check in 2 of 3).
+- **Named tickets** — group bookings can give each person their own ticket, shown
+  with their name on the PDF, the scanner and the staff ticket list.
+- **QR scanner** — works in any mobile browser. A preview checks the ticket is
+  for the selected event/section, then a confirmation screen shows holder, type
+  and remaining quantity.
+- **Check-in confirmation** — holders get an email/WhatsApp saying how many were
+  checked in and how many remain.
+- **Scan stats** — recent scans and per-event scan counts.
+- **Offline scanning** — while online, a staff member locks an event section (or the
+  whole event) to their device and downloads its tickets. They can then keep scanning
+  with no connection; scans are queued on the device and sync automatically when it's
+  back online (never redeeming more than is left). Only one device can hold a section,
+  and while it's locked nobody else can scan it, online or offline. Problems found
+  while syncing go into a report for a supervisor. Supervisors can force-release a
+  lost device. The scanner can be added to the home screen (PWA) and opens offline.
+- **Printing** — A4 sheets (8 tickets per page) and A6 single tickets.
+- **Resend** — send tickets to a different email/phone at the door.
+
+---
+
+## Attendee forms
+
+- **Form builder** per event — field types: Yes/No, Text, Paragraph, Number,
+  Date, plus Statement and Heading blocks; required/optional, help text,
+  reordering. The whole form can be marked required.
+- **Drafts** — partially filled forms are auto-saved.
+- **Responses** — view, filter (event, user, past/inactive) and print one
+  response per A4 page. Supervisors can edit responses.
+
+---
+
+## Messaging & notifications
+
+Every user picks a **notification preference**: Email, WhatsApp, or Both.
+
+**Automatic notifications**
+
+| Trigger | Goes to |
+|---------|---------|
+| Registration created / updated | Registrant (with invoice if unpaid) + event notify recipients |
+| Payment recorded / donation applied / unassigned | Registrant (with receipt) + admins |
+| Refund processed | Registrant + admins |
+| Tickets generated | Registrant (ticket PDF) |
+| Ticket checked in | Ticket holder |
+| Daily summary, 07:00, for each live event that hasn't started yet | Registrations inbox + event notify recipients |
+| Account registered, activation, login, password changed/reset, account closed | The account holder |
+
+**Bulk messaging** (supervisor)
+
+- **Email attendees** and **WhatsApp attendees** — filter by status or pick
+  specific attendees, preview, send now or schedule for later.
+- **Placeholders** — `{{name}}`, `{{event.title}}`, `{{event.link}}`,
+  `{{event.start}}`, `{{balance}}`, and `{{payment.link}}` (a live Yoco link for each recipient's
+  outstanding balance).
+- **Broadcasts** — ad-hoc email/WhatsApp to any users or addresses, not tied to
+  one event.
+- **Automations** — schedule a sequence of lifecycle emails for an event
+  (pre-event, final reminder, thank-you, promo for another event).
+- **Manage scheduled** — view, edit or delete queued jobs per channel. Sends
+  run in the background and are purged 24 h after sending.
+
+**WhatsApp** is connected through the WAWP API: an admin links a number in
+Site Settings → WhatsApp (QR code or pairing code), with status, restart and
+logout controls. Disconnected sessions are recovered automatically.
+
+---
+
+## User dashboard (My Events)
+
+- Registrations with status badges, event thumbnails, and Closed/Past/Inactive
+  tags. Past and closed events are hidden by default.
+- Registration detail: itemised bill (early-bird lines grouped), payments,
+  **Invoice** and **Receipt** buttons, edit, cancel, **Make payment**.
+- Upcoming events and tickets side by side, with bulk ticket email/WhatsApp.
+- **Ticket transfer** — hand a ticket to someone else before the event (name plus
+  email/phone). They get a new ticket and QR code, and an inactive account with an
+  activation link if they're new. The old code stops working, and scanning it says it
+  was transferred, both online and in offline-mode sync reports. One place can be split
+  off a ticket covering several people. Billing stays with the payer. It's not allowed
+  once a ticket has been scanned, and it can be turned off per event (supervisors can
+  always transfer, from At the door → Tickets). On youth events the new holder needs
+  their own parental consent, and the previous holder's form answers are removed.
+  Every transfer is in the audit log.
+- **Payment history** (`/dashboard/user/payments`) — paginated, with filters by
+  date, method and payment/refund.
+- **Donate** page.
+- **Forms** — complete outstanding attendee forms.
+- **Profile & Security** — edit details and notification preference, change
+  password, see recent account activity (logins, password changes, device),
+  sign out everywhere, deactivate or delete my data.
+
+---
+
+## Staff tools
+
+- **Staff dashboard** — scan stats and quick actions.
+- **Ticket scanning** (`/dashboard/staff/ticket-scanning`) — camera QR scanner
+  with event and section filters.
+- **Event tickets & printing** (`/dashboard/staff/event-tickets`) — list, search
+  and print an event's tickets.
+
+---
+
+## Supervisor tools
+
+- **Dashboard** — KPIs (active events, revenue, donations, registrations,
+  tickets sold, each vs. the previous month), revenue trend chart, top events,
+  and recent scans. Tiles link to the matching report.
+- **Manage events** — the 6-step event wizard, ticket options, variants,
+  sections, form and attachments.
+- **At the door** — search by name/phone/ticket ID, walk-in registration,
+  payments, a **Check-In** tab for redeeming main tickets by quantity, and
+  ticket printing/resending.
+- **Self-service kiosk** (`/self-service`) — a touchscreen page a supervisor
+  unlocks for an event, where visitors register themselves. Existing accounts
+  are matched by email/phone, and any change to their details needs
+  confirmation.
+- **Manual registration** — register someone on their behalf and record their
+  payment.
+- **Payments** — tabs for Payment, Refund, Donations (assign/unassign),
+  Reconcile (Yoco transactions), and Payment Link.
+- **Coupon codes** (`/dashboard/supervisor/coupons`) — create, edit and turn off
+  discount codes, and see who used each one.
+- **Rooms & groups** (`/dashboard/supervisor/allocations`):
+  - Per event, allocation sets such as "Rooms", "Small groups" or "Buses". Each set
+    has groups with an optional capacity, gender restriction and leader (staff).
+  - A drag-and-drop board, plus auto-allocate: fill evenly, respecting capacity and
+    gender, keeping bookings together or splitting them.
+  - Printable per-group and master lists. On youth events they can include medical
+    details, and viewing those is audited.
+  - The group can show on tickets and in My Events.
+  - Email and WhatsApp attendees can be filtered to one group.
+  - Leaders see their people under Staff → **My groups**.
+  - Works on named attendees. Events can ask each person's gender.
+- **Offline scanning** (`/dashboard/supervisor/offline-scans`) — devices holding
+  offline locks (with force release) and sync reports to review.
+- **Waitlist** (`/dashboard/supervisor/waitlist`) — the queue per event: offer a
+  place now, move people up or down, or remove them.
+- **Parental consent** (`/dashboard/supervisor/consent`) — consent status per
+  attendee on youth events, resend (one or all pending), re-request after the
+  consent text changes, and a printable medical & emergency list (audited).
+- **Email attendees / WhatsApp attendees** — bulk and scheduled messaging.
+- **Forms** — view, filter, edit and print form responses.
+- **Reports** — see [Reports](#reports).
+- **Site banner** (`/set-banner`) — set the announcement bar.
+
+---
+
+## Admin tools
+
+- **Admin dashboard** — same KPIs as supervisor, plus admin quick actions.
+- **Manage users** — server-side search and filters (role, active), paging,
+  edit role and notification preference, revoke sessions, delete or
+  **anonymise** personal data.
+- **Registrations** — all registrations, with filters (event, status, text),
+  status counts, revenue and outstanding totals, and per-registration options,
+  form answers and payments (with who recorded each one).
+- **Cashup** — see below.
+- **Audit log** (`/dashboard/admin/audit-log`) — who did what and when for
+  refunds, donation assign/unassign, manual registrations, staff
+  cancellations, event create/update/delete, settings changes, and coupon codes
+  (created, edited, turned off, applied or removed by staff).
+- **Site settings** — see below.

+## Cashup & event costs
+
+- **Event costs** — once-off or per-item costs (optionally linked to a ticket
+  option), with a "paid from takings" method so cash on hand is correct.
+- **Expected vs. actual** — expected takings per method (cash/card/EFT/other)
+  compared with actual amounts, with variance shown.
+- **Cash denomination counts** — entered per staff member, at any time. The
+  event's actual cash is the sum of these counts.
+- **Payment accountability by staff member** — what each person recorded, by
+  method, with live cash variance.
+- **Close / quick close / reopen** an event — closing locks it from further
+  edits and hides it from the kiosk and user actions. Drafts are saved as you
+  go.
+- **Report tab** — a read-only cashup summary, shown automatically once the
+  event is closed.
+- **Cashup audit trail** — every close/reopen with totals and who did it.
+
+---
+
+## Reports
+
+A full-width workspace with shared filters (events, date range with presets,
+include past/inactive/closed) and a searchable grid of reports, each opening in
+a viewer with its own filters, stat tiles and bar charts.
+
+| Category | Reports |
+|----------|---------|
+| Financial | Payments between dates · Revenue summary (by method) · Revenue detailed · Finance report (revenue & costs, after discounts) · Profit report · Discounts (coupon codes) |
+| Registration | Attendees per event (grouped by option) · Registration type counts · Master orders breakdown · Registration status breakdown (count by registration or ticket quantity) · Parental consent status · Medical & emergency list · Feedback summary (response rate, average ratings, choice breakdowns, comments; compare events) |
+| Ticketing | Ticket usage summary |
+| Donations | Donations breakdown (used / unused per event, plus the sponsorship pool) |
+| Cashup | Cashup reconciliation · Cashup audit trail |
+
+**Export:** Print, branded PDF download, styled Excel (`.xlsx`) workbook,
+Email (to yourself), or WhatsApp (the PDF to your own number). Dashboard tiles
+deep-link into reports with `?report=&range=`.
+
+---
+
+## Site settings & setup wizard
+
+**Setup wizard** (`/setup`) — on a fresh database, walks through organisation
+details, the first admin account and branding. No manual seeding needed.
+
+**Site Settings** (`/dashboard/admin/settings`) — stored in the database and
+applied without a restart. Secrets are encrypted with AES-256-GCM.
+
+| Tab | Contains |
+|-----|----------|
+| Organisation | Name, tagline, contact email/phone, address (with map link) |
+| Branding | Primary/secondary/accent colours, logo, favicon, colours suggested from the logo, live website/email preview on desktop and mobile |
+| Notifications | Registrations inbox and admin notification emails |
+| Email | SMTP host/port/TLS/user/password/from, with a "Test connection" button |
+| Legal | Operator, Information Officer, website, effective date for the Terms/Privacy pages |
+| WhatsApp | WAWP credentials, connect a number, status/restart/logout |
+| Backups | List, run now, download database backups |
+
+See [SETTINGS.md](./SETTINGS.md) for the default of every setting.
+
+---
+
+## Accounts & security
+
+- Register, log in, forgot/reset password, activate account (for accounts
+  created on someone's behalf).
+- JWT authentication (HS256 pinned) with **session revocation** (token
+  versioning) — users can sign out everywhere, and admins can do it for any user.
+- **Two-factor authentication** — a 6-digit login code by email or WhatsApp
+  (10-minute expiry, 5 attempts, resend), with "Trust this device for 30 days".
+  **Required for Admins and Supervisors**: their next login sends a code that turns
+  it on, and they can change the channel but not turn it off (skipped only when no
+  email or WhatsApp channel can deliver a code; `TWO_FACTOR_REQUIRED_ROLES=false`
+  is the emergency switch). Optional for everyone else from Profile & Security.
+  Admins can reset it for a locked-out user, and the kiosk asks for the code at
+  setup.
+- **Login lockout** after repeated failed attempts, plus login rate limiting
+  (`TRUST_PROXY` to read real IPs behind a proxy).
+- **Security event log** — logins, password changes and resets, with device
+  and IP.
+- **Account closure** — deactivate, or anonymise personal data while keeping
+  financial records.
+- **Upload hardening** — server-generated filenames, and uploads served with a
+  sandbox CSP and `nosniff`.
+
+---
+
+## Help system
+
+A floating **"Need help?"** button on every page opens a page-specific guide
+(tabs, quick links). Every page has dedicated content (`frontend/src/content/help/`),
+falling back to a general guide.
+
+---
+
+## Background jobs
+
+| Job | Schedule |
+|-----|----------|
+| Scheduled email/WhatsApp worker | Polls every 30 s (`SCHEDULED_EMAILS_INTERVAL_MS`) and purges sent jobs after 24 h |
+| Daily event summary email | 07:00 daily |
+| Waitlist: expire unclaimed offers, offer freed places | Every 10 minutes (`WAITLIST_JOB_ENABLED=false` to disable) |
+| Post-event feedback forms and their 3-day reminder | Every 15 minutes (`FEEDBACK_JOB_ENABLED=false` to disable) |

+| Database backup (`pg_dump`, gzipped, 14-day retention) | 02:00 daily (`BACKUP_ENABLED=false` to disable) |
+| Temp file cleanup (files older than 7 days in `/temp`) | Daily |
+
+---
+
+## Operations
+
+- **PM2** (`ecosystem.config.js`) runs backend and frontend, restarting either
+  one above 500 MB of memory.
+- **Sentry** error monitoring when `SENTRY_DSN` / `NEXT_PUBLIC_SENTRY_DSN` are
+  set.
+- Unhandled promise rejections are logged and don't crash the server.
+- Backend status page (`/`) and built-in API docs page (`/docs`).
+- Jest tests for early-bird tranche pricing and donation balances.
+- Versioning via git tags and [CHANGELOG.md](./CHANGELOG.md).

+# Site Settings — Defaults Reference
+
+Every setting below is stored as a row in the `AppSetting` key-value table and
+is editable at runtime via **Admin → Site Settings** (or, for the first few,
+the `/setup` wizard on a fresh install). None of them are required — this
+page documents exactly what happens when a given key has never been saved.
+
+Settings changes take effect within 60 seconds everywhere (the backend's
+in-process settings cache TTL) without a server restart.
+
+## Organisation
+
+| Setting | Default when unset | Notes |
+|---|---|---|
+| `org_name` | `"Cross Code"` | Falls back to `ORG_NAME` env var first, then this hardcoded default (the platform vendor's name, used as a neutral placeholder — `org_name` is a required field in the setup wizard, so this fallback is practically unreachable once a site has been set up). Shown in the navbar, email headers/subjects, and WhatsApp messages. |
+| `org_tagline` | `"Connecting community through events"` | Falls back to `ORG_TAGLINE` env var first. Shown under the org name in the email header. |
+| `org_email` | *(blank)* | No fallback in most places. **Exception:** the Terms of Use / Privacy Policy pages default to `privacy@example.com` (an obvious placeholder) if unset — see the Legal section below. |
+| `org_phone` / `org_address` | *(blank)* | No fallback — simply omitted wherever shown if unset. |
+| `app_base_url` | `APP_BASE_URL` or `FRONTEND_URL` env var, else `http://localhost:3001` | Used to build links in emails (password reset, ticket delivery, etc.). Should always be set in production. |
+
+## Branding
+
+| Setting | Default when unset | Notes |
+|---|---|---|
+| `primary_color` | Legacy `accent_color` value if present, else `#4F46E5` (indigo) on the website / `#1e3a5f` (navy) in emails | See [Two different fallbacks](#two-different-fallbacks-for-primary_color) below — this is the one setting with a genuine inconsistency worth knowing about. Drives buttons, links, nav highlights, and the email header/CTA. |
+| `secondary_color` | `210 40% 96.1%` background / near-black text (light gray "wash", shadcn's stock theme) | The Branding tab's color picker *pre-fills* `#8B5CF6` as a suggested starting point, but that's only a UI default — if you never hit Save, the actual site uses the light-gray fallback, not violet. |
+| `accent_color` | `210 40% 96.1%` background / near-black text (same light gray as Secondary) | Same story as Secondary — the picker pre-fills `#EC4899` (pink) as a suggestion only. |
+| `logo_url` | Bundled logo (`frontend/src/app/church_logo.jpg`) | Shown in the navbar. This is still the original Hope Family Church artwork checked into the repo — swap the file (or upload a real logo via the Branding tab) before deploying for a different organisation. |
+| `favicon_url` | `frontend/public/favicon.ico` (the site's original generic favicon) | Shown in the browser tab. |
+
+### Two different fallbacks for `primary_color`
+
+If `primary_color` has *never* been saved (no admin has ever used the new
+3-color Branding tab) **and** there's no legacy `accent_color` value either,
+the website and outgoing emails currently disagree on what "no color" means:
+
+- **Website** (`globals.css` / `tailwind.config.js` static defaults): `#4F46E5`, a bright indigo.
+- **Emails** (`backend/src/utils/email.js` `getOrg()`): `#1e3a5f`, a dark navy — unless overridden by the `EMAIL_HEADER_COLOR` env var.
+
+In practice this only matters on a brand-new install before the setup wizard
+or Branding tab has been saved even once — the wizard always writes
+`primary_color`, so this gap closes itself the moment setup completes.
+
+## Notifications
+
+| Setting | Default when unset | Notes |
+|---|---|---|
+| `reg_notification_emails` | `REGISTRATIONS_EMAIL` env var, else *(blank)* | If truly blank, no internal notification email is sent for new registrations/payments/donations — it's silently skipped, not an error. |
+
+## Email delivery (SMTP)
+
+| Setting | Default when unset | Notes |
+|---|---|---|
+| `smtp_host` | `SMTP_HOST`/`EMAIL_HOST` env var, else *(blank)* | If blank, the app **does not send real email** — it uses nodemailer's `jsonTransport`, which just logs the would-be email to the console. This is the single biggest "nothing is configured" gotcha — ticket/payment/password-reset emails silently don't go anywhere until SMTP is set up. |
+| `smtp_port` | `587` | |
+| `smtp_secure` | `false` | |
+| `smtp_user` / `smtp_pass` | *(blank)* | Stored AES-256-GCM encrypted (key derived from `JWT_SECRET`). |
+| `smtp_from` | *(blank)* | If blank, outgoing mail's `From:` address falls back to the literal `no-reply@crosscode.local`. |
+
+## Legal (Terms of Use / Privacy Policy)
+
+| Setting | Default when unset | Notes |
+|---|---|---|
+| `legal_operator_name` | `"[operator details not yet configured]"` | Deliberately a generic, obviously-incomplete placeholder rather than any real person's or organisation's name. Unlike `org_name`, these legal fields are optional and can realistically stay unset on a live site — defaulting them to Cross Code's (or anyone else's) real identity would misrepresent who's legally responsible for that deployment. |
+| `legal_io_name` | `"[not yet configured]"` | Same reasoning as `legal_operator_name`. |
+| `legal_io_email` | `"io@example.com"` | Rendered as a `mailto:` link, so the placeholder stays a syntactically valid address on the IANA-reserved `example.com` domain rather than a bracketed non-email string that would break the link. |
+| `legal_website_url` | `"example.com"` | Same reasoning — used to build an `https://` link. |
+| `legal_effective_date` | `"[not yet set]"` | Plain text only, no link — a bracketed placeholder is fine here. |
+| `consent_medical_retention_days` | `30` | Youth events: medical and emergency details from parental consent forms are deleted this many days after the event ends (daily 09:00 job). The consent record itself — who agreed, when, to which text — is kept. Set under Site Settings → Legal. |
+| `org_email` (as used on legal pages specifically) | `"privacy@example.com"` | Different fallback than `org_email`'s general default (blank) — also rendered as a `mailto:` link, so it needs to stay a valid-looking address. |
+
+## WhatsApp
+
+| Setting | Default when unset | Notes |
+|---|---|---|
+| `WAWP_ACCESS_TOKEN` / `WAWP_INSTANCE_ID` | `WAWP_ACCESS_TOKEN`/`WAWP_INSTANCE_ID` env vars, else *(blank)* | No hardcoded default — WhatsApp sending is simply unavailable until both are configured (Admin → Site Settings → WhatsApp). |
+
+## Backups
+
+| Setting | Default when unset | Notes |
+|---|---|---|
+| `backup_retain_count` | `14` | How many nightly backups to keep on disk (oldest deleted beyond this count). Editable at Admin → Site Settings → Backups. See `BACKUP_ENABLED` (env var) to turn the nightly job off entirely. |
+
+## Setup state
+
+| Setting | Default when unset | Notes |
+|---|---|---|
+| `setup_complete` | `false` (treated as `"not true"`) | Controls whether `/setup` redirects to `/login` or runs the first-time wizard. Set to `"true"` automatically when the wizard finishes. |

+
+**Required for admins and supervisors.** An admin or supervisor without 2FA gets the same challenge with `"enrolling": true` (trusted devices don't skip it), sent to their email when SMTP is configured, otherwise WhatsApp. Verifying it turns 2FA on with that channel.

+- `POST /api/users/2fa/enable` — `{ "method": "email" | "whatsapp", "password": "..." }` sends a code to that channel and returns `{ challengeId, method, destination }`. WhatsApp needs a valid phone number on the account and a connected WhatsApp session.

+- `POST /api/users/2fa/disable` — `{ "password": "..." }` turns it off. Returns 403 for admins and supervisors, who must keep it on (they can switch channel with `enable`/`confirm`).
+
+An admin or supervisor session without 2FA (from before the requirement, or after a promotion or 2FA reset) is rejected by every protected route with `401 { "code": "TWO_FACTOR_REQUIRED" }`; logging in again enrols them.

+| POST | `/api/sponsorships/checkout` | public (optional login) | `{ eventId, spots? \| amount?, anonymous?, sponsorName?, message?, name?, email? }` → Yoco `redirectUrl`. Guests give a name and email |
+| GET | `/api/sponsorships/event/:eventId/pool` | supervisor+ | `{ received, assigned, remaining, sponsors, spotsFunded, spotPrice, goalSpots }` |
+
+How the money is handled:
+- A spot costs the cheapest paid main ticket.
+- Yoco checkout metadata carries `type: 'sponsorship'`. The webhook records the payment as `isDonation` + `isSponsorship` against the event, together with `sponsorName`, `sponsorMessage` and `sponsorAnonymous`.
+- Pool funds are assigned with `PUT /api/payments/assign-donation`.
+
+Other changes:
+- Event fields: `allowSponsorships`, `sponsorshipGoalSpots`, `showSponsorshipProgress`.
+- `POST /api/events/:id/email-attendees` accepts `filter.audience: 'sponsors'`.
+- `POST /api/automations/schedule` jobs accept `audience: 'sponsors'`.

+

+| POST | `/api/allocations/sets` | supervisor+ | `{ eventId, name, showOnTicket? }` |
+| PUT / DELETE | `/api/allocations/sets/:id` | supervisor+ | Rename / show on tickets; delete |
+| POST | `/api/allocations/sets/:id/groups` | supervisor+ | `{ name, capacity?, gender? ('male'\|'female'), leaderUserId? }` |
+| PUT / DELETE | `/api/allocations/groups/:id` | supervisor+ | Edit (can't drop below current members or break gender); delete (members become unassigned) |
+| PUT | `/api/allocations/sets/:id/assignments` | supervisor+ | `{ attendeeId, groupId }` (null unassigns); enforces capacity and gender |
+| DELETE | `/api/allocations/sets/:id/assignments` | supervisor+ | Clear the set |
+| POST | `/api/allocations/sets/:id/auto` | supervisor+ | `{ mode: 'together' \| 'split' }` — places everyone not yet placed |
+| GET | `/api/allocations/sets/:id/lists?medical=true` | supervisor+ | Groups with members for printing (medical view is audited) |
+| GET | `/api/allocations/my-groups` | staff+ | Groups the caller leads (medical details for supervisors only) |
+
+Related changes:
+- `Event.collectGender` makes a gender (`male` / `female`) required for each named attendee.
+- Email and WhatsApp attendees accept `filter.allocationGroupId`.
+
+## Ticket transfer
+
+| Method | Path | Auth | Description |
+|--------|------|------|-------------|
+| POST | `/api/tickets/:id/transfer` | payer, holder or supervisor+ | `{ name, email?, phone?, dateOfBirth?, parentName?, parentEmail?, parentPhone? }` (date of birth, plus parent details for a minor, on youth events) |
+| GET | `/api/tickets/:id/transfers` | payer, holder or staff+ | Transfer history |
+
+Rules:
+- Only before the event starts, and only for tickets that have never been scanned.
+- `Event.allowTicketTransfer` turns it off for non-supervisors.
+
+What a transfer does:
+- The new holder becomes the ticket's attendee and gets a new QR code. A shared ticket for several places has one place split off into its own ticket.
+- An account is matched by email/phone, or created inactive with an activation link.
+- The previous holder's attendee form answers are deleted, and the medical details on their consent are cleared. A minor on a youth event gets a new consent request.
+
+Old QR codes:
+- `scan-preview` and `scan` return `410 { code: "TICKET_TRANSFERRED" }`.
+- Offline sync reports them as `transferred`.
+- Each transfer is audited as `ticket_transferred`.
+
+## Offline scanning
+
+| Method | Path | Auth | Description |
+|--------|------|------|-------------|
+| GET | `/api/scan-locks?eventId=` | staff+ | Active offline locks for an event |
+| POST | `/api/scan-locks` | staff+ | Lock `{ eventId, sectionId?, deviceId, deviceName? }` to this device (409 if the scope is held elsewhere) |
+| GET | `/api/scan-locks/:id/snapshot?deviceId=` | staff+ | Tickets valid in the lock's scope (lock holder only) |
+| POST | `/api/scan-locks/:id/sync` | staff+ | `{ deviceId, scans: [{ clientScanId, qrCode, qty, scannedAt }] }` — idempotent; returns accepted, duplicates, conflicts |
+| DELETE | `/api/scan-locks/:id` | staff+ | Release (`{ deviceId }`, lock holder only) |
+| POST | `/api/scan-locks/:id/force-release` | supervisor+ | Release a lost device's lock |
+| GET | `/api/scan-locks/reports?eventId=&unreviewed=` | supervisor+ | Sync reports |
+| POST | `/api/scan-locks/reports/:id/review` | supervisor+ | Mark a report reviewed |
+
+How locks work:
+- One device per scope. A whole-event lock (`sectionId` null) clashes with every section lock on that event.
+- `POST /api/tickets/scan/:qrCode` now accepts `sectionId` and `deviceId`. It enforces the section on the server, and returns `423 { code: "SCAN_LOCKED" }` when another device holds a lock covering the ticket.
+
+How syncing works:
+- Synced scans never redeem more than is left on a ticket.
+- Conflicts are recorded in the sync report: `not_found`, `cancelled`, `wrong_scope`, `already_used`, `partly_used` and `consent`.
+- Check-in messages are sent after the sync.
+- Locks, releases, force-releases and syncs are written to the admin audit log.
+
+## Waitlist
+
+Events with `waitlistEnabled` (plus `waitlistOfferHours`, default 24, and `waitlistPartialOffers`, default true) take a queue for sold-out lines.
+
+| Method | Path | Auth | Description |
+|--------|------|------|-------------|
+| POST | `/api/waitlist` | optional | Join: `{ eventId, eventOptionId, variantId?, quantity }` (+ `guestName`, `guestEmail`, `guestPhone` when not logged in on a guest event). Only when the line can't cover the quantity |
+| GET | `/api/waitlist/mine` | user+ | My active entries |
+| DELETE | `/api/waitlist/:id` | user+ | Leave (an open offer moves on) |
+| GET | `/api/waitlist/claim/:token` | public | What a claim link offers |
+| GET | `/api/waitlist/events/:eventId` | staff+ | The queue for an event |
+| POST | `/api/waitlist/:id/offer` | supervisor+ | Offer now (`{ quantity? }`), even over the stock limit |
+| POST | `/api/waitlist/:id/move` | supervisor+ | `{ direction: "up" \| "down" }` |
+| POST | `/api/waitlist/:id/remove` | supervisor+ | Take someone off |
+
+How offers work:
+- Places held for a live offer count as taken everywhere stock is counted: `availableCount`, `isSoldOut` and registration stock checks.
+- Offers are made automatically when places free up: a cancellation, a smaller booking, or a raised stock limit.
+- A job every 10 minutes (`WAITLIST_JOB_ENABLED`, `WAITLIST_JOB_INTERVAL_MS`) expires unclaimed offers and re-offers.
+- Claiming means registering with `POST /api/registrations` plus `waitlistToken`. The token stands in for logging in, and the held places are released to the claimer.
+- Manual registration and adding places to an existing booking are now checked against stock too.
+
+## Parental consent
+
+Youth events (`requiresParentalConsent`, plus `consentText`, `consentCollectMedical`, `consentCollectEmergency` and `consentCollectPhoto` on the event) need every main place named with a `dateOfBirth`. Attendees under 18 on the start date also need `parentName`, `parentEmail` and `parentPhone`. Changing `consentText` bumps `consentTextVersion`.
+
+| Method | Path | Auth | Description |
+|--------|------|------|-------------|
+| GET | `/api/consent/:token` | public | What the parent sees: attendee, event, consent text, fields to fill in |
+| POST | `/api/consent/:token` | public | `{ decision: "give"\|"decline", signedName, isGuardian: true, medical?, emergency?, photoConsent? }` |
+| GET | `/api/consent/events/:eventId` | staff+ | Consent status per attendee, with counts |
+| POST | `/api/consent/requests/:id/resend` | user+ | Re-send one request with a new link (registrant or staff) |
+| POST | `/api/consent/events/:eventId/resend-pending` | supervisor+ | Re-send every pending request |
+| POST | `/api/consent/events/:eventId/rerequest` | supervisor+ | New requests for consent given on older text, and minors with none |
+| GET | `/api/consent/events/:eventId/medical` | supervisor+ | Decrypted medical & emergency list (audited as `medical_list_viewed`) |
+
+How requests work:
+- Requests go to the parent by both email and WhatsApp, whatever anyone's notification preference.
+- Links are random tokens; only an HMAC is stored. They expire when the event ends.
+- The answer stores the signed name, time, IP, device, and the exact text and version shown.
+- Medical and emergency details are AES-256-GCM encrypted. A daily job (09:00, `CONSENT_JOBS_ENABLED=false` to disable) sends reminders (day 2, then every 3 days) and deletes them `consent_medical_retention_days` (default 30) after the event.
+
+Check-in rules:
+- `GET /api/tickets/scan-preview/:qrCode` returns `consentStatus` (`not_required`, `missing`, `pending`, `given` or `declined`).
+- `POST /api/tickets/scan/:qrCode` returns `403 { code: "CONSENT_REQUIRED" }` unless consent is given.
+- Supervisors can pass `overrideConsent: true`, which is audited as `consent_override`.
+
+## Coupons
+
+| Method | Path | Auth | Description |
+|--------|------|------|-------------|
+| POST | `/api/coupons/validate` | optional | Check a code against a basket (`{ code, eventId, options, forUserId? }`) |
+| GET | `/api/coupons` | supervisor+ | List codes with use counts and total discount |
+| POST | `/api/coupons` | supervisor+ | Create a code |
+| GET | `/api/coupons/:id` | supervisor+ | One code with its uses |
+| PUT | `/api/coupons/:id` | supervisor+ | Edit or turn off a code |
+| GET | `/api/coupons/redemptions` | supervisor+ | Uses for the Discounts report (`eventIds`, `from`, `to`) |
+
+- **Types:** `percent` (value 1–100), `fixed` (rand amount), `comp` (free).
+- **Scope:** `eventIds` (none = every event) and `options: [{ eventOptionId, variantId? }]` (none = the whole registration).
+- **Restrictions:** `userIds`, `restrictRoles` and `restrictDomain`. A match on any one is enough, and restricted codes need a known account.
+- **Limits:** `validFrom`, `validUntil`, `maxUses`, `maxUsesPerUser` (default 1) and `minQuantity`.
+- **Early-bird:** `stackEarlyBird: false` means the better price wins; `true` discounts the early-bird price.
+- **Locked amount:** the discount is locked when applied. Editing items recalculates percentage and comp codes, but fixed codes keep their amount. Cancelling releases the use.
+
+Options and variants also accept an optional `staffPrice`, charged automatically to Staff and above when it's lower than the normal price.

+ * - Cancelling a registration releases its redemption, freeing the use.
+ * - Scope: no CouponOption rows = the whole event; otherwise only matching options
+ *   (or one variant of an option).
+ * - stackEarlyBird=false means "best price wins": the coupon is worked out against the
+ *   standard price, and only the part that beats the early-bird price is discounted.
