EarningsState (pending|eligible|paid|clawback_applied) is a client display model derived server-side; PayoutStatus is the contract's pending|submitted|paid|failed. Money = IRR digit-strings (gross=commission+payout; net=gross−clawback; Σ booking-links=grossEarnings); the net payable balance is SIGNED (may be negative "owed back", never clamped); eligibility/dates/amounts are server truth (never computed client-side); the BNPL provider commission never appears (payment-method-invariant).

+ * **jumps to the existing thread** instead of spawning duplicates.
+ * - **Optimistic send.** `postMessage` appends as the current viewer (tracked from the last `getTicket`);

+- **Shipped:** the social/communication layer for the customer **and** nurse apps (role decides chrome, not

+ new `referenceCode`); **thread** (`/…/tickets/[id]`) role-aware bubbles + sticky composer; **notification

+ screens); `notificationDeepLink`/`parseNotificationData` unit-tested; `support`/`send` icons; `tickets` +
+ `notifications` i18n namespaces + `nav.support` (both locales).
+- **Consumes:** dev/contracts/domains/messaging-notifications-admin.md (b15 tickets) + config-reference.md (b1

+ `GET /tickets/{id}`, `POST /tickets/{id}/messages`; `GET notifications/get_notifications`,
+ `get_unread_count`, `POST mark_notification_read` / `mark_all_read`.
+- **Critical rules honoured:** `is_internal` is **never** modelled in the user-app types — both API mappers DROP
+ any internal message (server-strip mimic), no internal affordance anywhere; the emergency surface is a
+ **post-confirmation `tel:` playbook only** (nurse-gated care contact, no VoIP seam, never a general phone);
+ the unread **count** polls politely (60s interval + 45s staleTime + refetch-on-focus, auth-gated) and the list
+ is never polled; `data_json` is parsed into a typed union and degrades to no-deep-link.
+- **Mocked client-side:** `services/tickets` (`USE_TICKETS_MOCK`) — b15 is live and `ticketsClientApi` maps it
+ 1:1, but the linked bookings are mock-primary and the summary lacks `unreadCount`/`lastMessageAt` (REQ-028);

+## REQ-028 — Ticket inbox enrichment (unread + last-activity), message author name, by-booking lookup, optimistic idempotency — filed by frontend-phase-14-b15 — 2026-07-10
+- **Need:** Four additions the f14 messaging UI renders that the b15 `TicketSummaryDto`/`TicketThreadDto`/message
+ routes don't yet expose (the two ticket screens work today because `services/tickets` is **mock-primary** —
+ `USE_TICKETS_MOCK = true`; the real `ticketsClientApi` maps every live b15 route 1:1 and leaves these blank):
+ 1. **`unreadCount` + `lastMessageAt` on `TicketSummaryDto`.** The inbox card shows an **unread indicator** and
+ sorts/labels by **last activity**, but the wire summary carries only `createdAt` (no unread, no last-message
+ time). Today the client falls back to `createdAt` and hides the unread badge on the real path; the mock
+ supplies both. Proposed: `TicketSummaryDto { …, lastMessageAt: string (UTC), unreadCount: int }` (unread =
+ messages after the caller's `last_read_at`, internal excluded).
+ 2. **A message author display label on `TicketMessageDto`** (or on `TicketParticipantDto`). The thread bubble
+ labels each message by author, but the DTO carries only `senderId` — no name. The client derives the label
+ from the participant **role** (`author_customer`/`author_nurse`/`author_support`/`author_system`) and never
+ shows a raw identity (privacy — the thread is deliberately not a contact directory). Please **confirm this
+ role-label approach is intended**, or add a **server-masked** display name if a name is wanted. (No phone /
+ no real name is the safe default.)
+ 3. **A user-facing by-booking ticket lookup/filter.** `GET /tickets` (the user list) filters only by
+ `Status`/`ReferenceCode` — there's no `bookingId` filter (only the **admin** list has one). The
+ "Get support" action on a booking is specced to **jump to the existing coordination ticket** if one exists;
+ without a by-booking read the client can't find it. The mock approximates this via idempotent
+ `openTicket(category:'coordination', bookingId)` (returns the existing thread). Proposed: add a `bookingId`
+ query param to `GET /tickets`, or `GET /tickets/by_booking/{bookingId}?category=coordination`.
+ 4. **An idempotency / `clientMessageId` field on `POST /tickets/{id}/messages`.** The optimistic send generates a
+ `clientMessageId` to reconcile the pending bubble; the server has no field for it, so a retried send (network
+ flap) could create a duplicate server-side. The client does **not** send it today (reconciliation is
+ client-only). Proposed: accept an optional `clientMessageId`/`idempotencyKey` on the post-message body and
+ dedupe on it, echoing it back on `PostMessageResult`.
+- **Why:** the f14 inbox (unread + last-activity), the thread (author labels + jump-to-coordination), and the
+ optimistic composer render these; the domain is mock-primary precisely because (1)/(3) aren't served and the
+ linked bookings are themselves mock-primary. When they land the swap is a single `USE_TICKETS_MOCK = false` flip
+ (no hook/component change) — `ticketsClientApi` already maps the live routes.

+# Frontend Phase 14 — Messaging (tickets) & notifications — report
+
+**Track:** frontend · **Depends on:** frontend-phase-8-b9 (booking detail) · **Consumes:** b15 tickets
+([messaging-notifications-admin.md](../../contracts/domains/messaging-notifications-admin.md)) + b1 notifications
+([config-reference.md](../../contracts/domains/config-reference.md)) · **Unlocks:** frontend-phase-15-b15 (admin
+& partner consoles — reuses these services with the admin lens). Date: 2026-07-10.
+
+The mission: give families and nurses the **only** sanctioned way to talk after a booking — the admin-readable
+**ticket** system — plus the in-app **notification center** + polled **bell**, and the **emergency playbook
+banner** on booking/support entry. No live chat by design; structured, auditable, anti-disintermediation.
+
+---
+
+## 1. What was built
+
+### Two new domain services (copied the `auth`/`reviews` skeleton exactly)
+- **`services/tickets`** — `types.ts` (client model, deliberately **no `isInternal`**), `keys.ts` (one
+ `detail(id)` = the whole thread; there is no message pagination in the contract — a `select`-based
+ `useTicketThread` derives the messages, mirroring f8 `useBookingSessions = select over detail`), `constants.ts`
+ (`USE_TICKETS_MOCK`, stale times, `MOCK_SEND_FAIL_SENTINEL`, per-role `MOCK_VIEWER_USER_ID`), `apis/`
+ (`clientApi` maps b15 1:1 + **drops any internal message defensively**, `mockApi` PRIMARY, selecting `index`),
+ hooks `useMyTickets` / `useTicket` / `useTicketThread` / `useOpenTicket` / `usePostMessage` (+ internal
+ `useTicketViewer`), barrel.
+- **`services/notifications`** — `types.ts` (`AppNotification` + discriminated `NotificationData` union),
+ `parse.ts` (`parseNotificationData` — snake/camel-tolerant, degrades to `{kind:'none'}`), `deepLink.ts`
+ (`notificationDeepLink(n, role)` — role-aware, `null` when nothing to open), `keys.ts`, `constants.ts`
+ (`USE_NOTIFICATIONS_MOCK`, poll interval/staleTime), `apis/` (`clientApi` maps b1 1:1, `mockApi` PRIMARY),
+ hooks `useNotifications` / `useUnreadCount` (**the poller**) / `useMarkNotificationRead` / `useMarkAllRead`,
+ barrel (+ re-exports `notificationDeepLink`).
+
+### Screens (shared by the customer **and** nurse apps — role decides chrome, not components)
+- **My Tickets inbox** — `/support/tickets` (customer) + `/nurse/support/tickets` (nurse), both thin wrappers
+ over ``: prominent `referenceCode`, status chip (reused `StatusChip`), unread
+ indicator, null-safe linked-entity hint, relative Shamsi time; empty/loading-skeleton/error→retry; a
+ **Contact support** dialog (category → subject → message → submit → shows the new `referenceCode`).
+- **Ticket thread** — `/…/tickets/[id]`: role-aware bubbles (mine vs theirs, **RTL-mirrored**), `referenceCode`
+ in the header, linked-booking chip, sticky **optimistic** composer; thread skeleton / empty / error states;
+ **never any internal-note content or affordance**.
+- **Notification center** — `/notifications` + `/nurse/notifications` (``):
+ unread-first list, each row **marks read on open** (optimistic) and **deep-links via `notificationDeepLink`**;
+ **Mark all read**; empty ("بهروز هستید") / loading / error→retry; a growing-limit "load more".
+- **Notification bell** — `` in the customer TopBar (+ a support icon) and the nurse
+ shell (via a new `headerActions` slot on `TopBarAndSideBarLayout`; a Support item added to the nurse sidebar).
+ It subscribes to the polling count so **only the bell re-renders** on a change, never the shell.
+- **Emergency banner + support entry on the f8 booking detail** — ``
+ (page-local glue, mounted below `BookingDetailView` on both the customer `/bookings/[id]` and nurse
+ `/nurse/visits/[id]` pages). It **reuses the cached booking query** (same key/viewer — no refetch) and, for
+ the **nurse on a post-confirmation booking**, the cached care-instructions read to surface the emergency
+ banner's `tel:` contact. Pre-confirmation → nothing. Customer → the support CTA only (no clinical phone).
+
+### Shared composites (co-located `*.test.tsx`)
+`MessageBubble` (mine/theirs, RTL, no internal styling), `TicketListCard` (prominent ref code + unread + null-safe
+link), `EmergencyBanner` (post-confirmation `tel:` playbook, no VoIP seam), `NotificationRow` (unread emphasis +
+server title/body), `NotificationBellView` (pure badge), `ContactSupportDialog`. Plus unit tests for
+`notificationDeepLink` and `parseNotificationData`. **+32 test cases; the full suite is 66 suites / 289 tests.**
+
+### i18n + icons + routes
+`tickets` + `notifications` namespaces added to **both** `fa.json` and `en.json` (in sync, RTL-first) + `nav.support`;
+`support` + `send` icons; route constants + role-aware path helpers (`ticketThreadPath`, `notificationsPath`, …).
+
+---
+
+## 2. Critical rules honoured (phase §5)
+
+- **`is_internal` never reaches the user app.** No `isInternal` field in the user-app types, no internal styling,
+ no internal-note affordance anywhere. **Both** API mappers (`ticketsClientApi.mapThread` and the mock's
+ `toDetail`) **drop** any message flagged internal — the mock even stores an internal admin note it never
+ returns, so the no-leak behaviour is demonstrable.
+- **No out-of-band channel except the post-confirmation emergency `tel:`** — drawn from the nurse-gated f8 care
+ read; the customer never sees a phone; no VoIP/calling seam; no SLA timers.
+- **`referenceCode` shown prominently** in the inbox card + thread header.
+- **Polite polling** — only `useUnreadCount` polls (60s `refetchInterval` + 45s `staleTime` + refetch-on-focus,
+ auth-gated); the notification **list is never polled**.
+- **Optimistic send is draft-preserving** — `onMutate` appends a pending bubble; `onError` rolls back to the
+ snapshot; the composer keeps the draft (cleared **only** on server confirm) and retries; reconcile by
+ `clientMessageId` (no double-render); submit disabled while sending. The composer is **keyed on `ticketId`**
+ so a draft / in-flight send never crosses a thread→thread navigation.
+- **`data_json` is a typed contract** — parsed into the discriminated union, deep-linked off that, degrades to
+ no-deep-link for an unknown type / missing id, never trusts a blob.
+- **Tenancy / null links** — reads are server-scoped; ticket↔booking/refund chips render only when present.
+
+---
+
+## 3. How to test (what a human can verify) — the phase §7 steps
+
+Run `npm run dev` (mocks are primary — `USE_TICKETS_MOCK`/`USE_NOTIFICATIONS_MOCK` default `true`):
+
+1. **Open a ticket from a booking.** Confirmed booking detail → **"Get support / Open ticket"** → a coordination
+ ticket opens (booking 5001 already has one → it **jumps to the existing thread**, else creates) and lands in
+ **My Tickets** with its `referenceCode`. *Expected:* it appears at the top of the inbox with no manual refresh.
+2. **Post a message (optimistic).** Open a thread, type, send → the bubble appears **immediately** ("sending") then
+ resolves to "sent". Send the dev sentinel body **`/fail`** → the bubble rolls back, **the text stays in the
+ composer**, and the "send failed" hint shows; edit + resend succeeds. *Expected:* no duplicate bubble, no lost draft.
+3. **No internal notes leak.** Ticket 1201 (coordination, booking 5001) has a **seeded internal admin note** — the
+ user thread shows **none of it**, no styling, no affordance.
+4. **Notification bell.** From the console call `window`-reachable dev helper (or import) `__mockPushNotification('ticket_message','پیام جدید','{"ticket_id":1201}')` → the **bell badge increments** within ~60s. Open the center,
+ open a notification → it **marks read**, the **badge decrements**, and it **deep-links** (booking → `/bookings/{id}`,
+ ticket → `/support/tickets/{id}`, etc.). **Mark all read** clears the badge. *Expected:* the count is served from
+ cache instantly and revalidates in the background; the endpoint isn't hit more often than the interval.
+5. **Emergency banner.** On a **confirmed** booking in the **nurse** app, the banner shows with a `tel:` link
+ (booking 5001/5002 have a seeded contact) + the playbook copy; on an **unconfirmed** booking it is **absent**.
+ The support entry (inbox) shows the playbook without a specific phone.
+6. **RTL + locales.** Switch `fa`/`en`: bubbles mirror, the badge sits correctly, every string is translated.
+ `npm run check` + `npm run test:ci` pass.
+
+---
+
+## 4. Mocks behind the two seams (swap = one flag)
+
+Both domains are **mock-primary** — recorded in [mocks-registry.md](./mocks-registry.md):
+
+- **`services/tickets` (`USE_TICKETS_MOCK = true`)** — `ticketsClientApi` maps every live b15 route 1:1
+ (`POST/GET /tickets`, `GET /tickets/{id}`, `POST /tickets/{id}/messages`) and defensively drops any leaked
+ internal message. The mock is primary because the linked bookings are themselves mock-primary and the wire
+ summary lacks `unreadCount`/`lastMessageAt` (**REQ-028**). It seeds 3 tickets (incl. the no-leak internal note
+ + a booking-linked coordination ticket with idempotent open), a clears-on-open unread count, an optimistic
+ append attributed to the current viewer (`openTicket` now takes the viewer id; `postMessage` tracks the
+ last-viewed thread's viewer), a closed-ticket `403`, and the `/fail` failure trigger.
+- **`services/notifications` (`USE_NOTIFICATIONS_MOCK = true`)** — `notificationsClientApi` maps every live b1
+ route 1:1. The mock is primary because nothing dispatches notifications client-side yet. It seeds an
+ unread-first feed spanning every deep-link class (each mapped through the **real** `parseNotificationData`) and
+ exposes `__mockPushNotification` for the bell-increment demo.
+
+Flip either flag to `false` (one line in `apis/index.ts` selection via `constants.ts`) — no hook/component change.
+
+---
+
+## 5. Contract consumed + gaps filed
+
+Consumed: `messaging-notifications-admin.md` (b15) + `config-reference.md` (b1) + `openapi/swagger.v1.json`
+(`TicketSummaryDto`/`TicketThreadDto`/`TicketMessageDto`/`OpenTicketCommand`/`OpenTicketResult`/`PostMessageCommand`/
+`PostMessageResult`; `NotificationDto`/`UnreadCountResult`/`MarkNotificationReadCommand`).
+
+Gap filed — **REQ-028** in [for-backend.md](../frontend/requests/for-backend.md): (1) `unreadCount` + `lastMessageAt`
+on `TicketSummaryDto`; (2) a message author label / confirm masked-by-design (the client uses the participant
+**role** label, never a raw name); (3) a **user-facing by-booking ticket lookup** (only the admin list filters by
+`bookingId`) so "Get support" can jump to the existing coordination thread on the real path; (4) an optional
+`clientMessageId`/idempotency field on `POST …/messages`. Business-rule drift check: the contract does **not**
+expose `is_internal` to users (the user `GET /tickets/{id}` is server-stripped) — no drift; the client models it
+accordingly.
+
+---
+
+## 6. Review + gate
+
+- **6-dimension adversarial review** (leak-and-tenancy, optimistic-send, notifications-cache-poll,
+ conventions-rtl-i18n, contract-fidelity, reuse-bugs) with per-finding adversarial verification. **1 finding
+ survived verification** — the mock `openTicket` mis-attributing a nurse-opened ticket's first message to the
+ customer (module-global `lastViewerUserId` defaulted to the customer). **Fixed** by threading the viewer id
+ through the `openTicket` seam (real path ignores it; server infers the sender) and adding the opener as a
+ participant. A second flagged item (composer state crossing a thread→thread navigation) did **not** survive
+ verification, but the composer was **keyed on `ticketId`** anyway as a correct-by-construction safeguard.
+- **Gate:** `npm run check` green; `npm run test:ci` green (66 suites / 289 tests, +32); production build
+ **compiles + type-checks clean**. A pre-existing "Missing .env variable" prerender guard fails SSG on
+ `/en/addresses` + `/en/nurse/verification/identity` only — unrelated to this phase (sibling pages under the
+ same modified shells prerender fine); not introduced here.
+
+---
+
+## 7. Follow-ups for frontend-phase-15-b15 (the admin lens)
+
+- The admin **global ticket queue** (`GET /admin/tickets` + `GET /admin/tickets/{id}` with internal messages) and
+ the **internal-note composer** layer on top of `services/tickets` — reuse the domain, add an admin-only
+ `isInternal` toggle **only in the admin view** (never in the user-app types).
+- The **support-alert worklist** (`support_alerts/*`) + **partner-center** console + **audit viewer** are b15/b1
+ admin surfaces (DEFERRED here).
+- When REQ-028 lands, flip `USE_TICKETS_MOCK = false`; when upstream domains dispatch real notifications, flip
+ `USE_NOTIFICATIONS_MOCK = false`.

Clinical text is fixture data (never logged) | `USE_PATIENT_RECORDS_MOCK` (`services/patientRecords/constants.ts`, default `true`) | Deliver **REQ-027** (family-owned `care_record` GET/PUT + `record_access` + structured `taskResults`), then set flag `false` — the history/append methods already map the real b14 routes; only the family-record/access methods flip. Confirm whether the family-owned record is a real MVP entity | 🟡 |
| f8 bookings mock — completed-booking seed 5005 + f13 cross-mock reads | `client/src/services/bookings/apis/mockApi.ts` | **Non-seam additions (mirrors the f10 refunds precedent).** The f8 seeds had **no `completed` booking** (only `confirmed`/`in_progress`/`cancelled`), so f13's review flow needs one: added **booking 5005** (`status: 'completed'`, nurse 1, patient 905, one completed EVV session) so the customer can open a completed booking and leave a review. Also added a **cross-mock read helper** — `mockGetBookingForReview(id)` (single booking, clone) — imported by the reviews mock to gate eligibility and read the patient/nurse snapshot for a submission (the `listBookings` seam row omits `patientId`/`nurseId`). One-way edge INTO bookings (the bookings mock never imports f13), so no cycle | — (part of `USE_BOOKINGS_MOCK`) | When the bookings flow goes real (b9/b10 conversion live), 5005 stops being a static seed and the cross-mock helpers retire with the reviews/records mocks | 🟡 |
+| `TicketsApi` | `client/src/services/tickets/apis/mockApi.ts` | **The f14 ticket channel (b15).** b15 serves open/list/thread/message and `ticketsClientApi` maps them 1:1 — but the linked bookings are themselves mock-primary and the wire summary lacks `unreadCount`/`lastMessageAt` (**REQ-028**), so the mock is primary. It seeds 3 tickets (a booking-5001 **coordination** ticket with a **stored internal admin note the user view NEVER returns** — the no-leak demo — plus a support + a closed refund ticket), returns them newest-activity first with a per-ticket unread count that **clears on open**; `openTicket` is **idempotent for `coordination + bookingId`** (so "Get support" from a booking jumps to the existing thread) and prepends a new ticket to the inbox; `postMessage` appends as the current viewer (tracked from the last `getTicket` so an optimistic message reconciles as **mine** in whichever app is open), throws `403` on a **closed** ticket, and throws `500` on the dev sentinel body `'/fail'` (the optimistic failure→retry path). `MOCK_VIEWER_USER_ID` (per-role "me") drives `isMine`; **`isInternal` is never modelled in the user-app types** | `USE_TICKETS_MOCK` (`services/tickets/constants.ts`, default `true`) | Deliver **REQ-028** (`unreadCount`/`lastMessageAt` on the summary + a by-booking user lookup + optional author name + optional `clientMessageId` idempotency) and make the upstream bookings flow real, then set flag `false` — `ticketsClientApi` already maps the live b15 routes 1:1 (drops any leaked internal message defensively). No hook/component change | 🟡 |
+| `NotificationsApi` | `client/src/services/notifications/apis/mockApi.ts` | **The f14 notification center + polled bell (b1).** The b1 endpoints are live and `notificationsClientApi` maps them 1:1, but a notification only exists once some other backend domain **dispatches** one (`INotificationDispatcher`) — none run client-side while the upstream flows are mock-primary — so there'd be nothing to show. The mock seeds a realistic **unread-first** feed spanning **every deep-link class** (ticket_message/booking_confirmed/refund_processed/payment_captured/payout_paid/review_published + one unknown-type/no-payload row that degrades to no deep-link), each with a snake_case `dataJson` string the list maps through the **real** `parseNotificationData`; `getUnreadCount`/`markRead`/`markAllRead` mutate the in-memory feed. **Dev-only `__mockPushNotification(type,title,dataJson?,body?)`** prepends a fresh **unread** row so a human can watch the bell badge increment within the poll interval (phase §7 step 4). Ids align with the f8 bookings + tickets mocks so a deep-link lands on a real screen | `USE_NOTIFICATIONS_MOCK` (`services/notifications/constants.ts`, default `true`) | When the upstream domains dispatch real notifications, set flag `false` — `notificationsClientApi` already maps the live b1 `notifications/*` routes 1:1 (`page`/`pageSize`, `{count}`, `{notificationId}`). No hook/component change | 🟡 |
