+# EDR Passenger — Playwright UI E2E
+
+Browser E2E for the passenger platform. **Track A** = portal booking combinations; **Track B** =
+backoffice config → portal propagation. Scenario matrix: `docs/ui-e2e-test-matrix.md`.
+
+## Status
+
+**Track A + Track B implemented and green** — 27 passing specs, 1 documented skip (UA-7). Full suite
+runs deterministically in ~1.8 min (`workers:1`, one seeded DB shared serially). The whole booking
+flow is factored into `fixtures/booking-flow.ts` — `bookTrip(page, opts)` drives an arbitrary
+passenger mix, nationality, trip type, promo, and payment method end to end (search → select →
+passengers → seats → review → pay → confirmation), capturing the price at each hop; `bookOneAdult` is
+a thin back-compat wrapper.
+
+### Coverage vs `docs/ui-e2e-test-matrix.md`
+
+**Track A — booking combinations** (`specs/portal`, `specs/guest`):
+
+| ID | Spec | What it proves |
+|----|------|----------------|
+| UA-1 | `ua1` | one-way 1A ETB WALLET — full money chain equal, CONFIRMED |
+| UA-1b | `ua1b-usd-divergence` | 🔴 USD card display fare diverges 100× from internal `baseFareMinor` |
+| UA-2 | `ua2-usd-booking` | 🔴 USD booking — reviewed total (ETB) vs stored total (USD) diverge 100× |
+| UA-3 | `ua3-djf` | DJF booking settles via forged gateway payment |
+| UA-3w | `ua3-djf` | 🔴 DJF WALLET — reviewed (DJF) vs stored (ETB) diverge |
+| UA-4 | `ua4-child-free` | first child <5 free → total = one adult fare, free child not seated |
+| UA-5 | `ua5-second-child-paid` | 1A+2C → second child pays full fare (2 seats) |
+| UA-6 | `ua6-round-trip` | 🔴 round-trip inbound leg has availability but no priced coach (booking blocked) |
+| UA-8 | `ua8-promo-drop` | ✅ valid promo now applied server-side; booking stored at the discounted total (H-13 fixed & guarded) |
+| UA-11 | `ua11-expired-promo` | expired promo ignored → full fare booked |
+| UA-13 | `ua13-forged-total` | ✅ client-forged `reviewedTotalMinor=1` now REJECTED 4xx, nothing stored (C-1 fixed & guarded) |
+| UA-14 | `ua14-forged-seat-fare` | ✅ guest forged `seatFareMinor=0` now REJECTED 4xx, nothing stored (C-1 fixed & guarded) |
+| UA-15 | `ua15-telebirr-shortpay` | ✅ short-paid gateway settlement now REFUSED — booking stays unconfirmed (C-4 fixed & guarded) |
+| UA-16 | `ua16-family-mix` | 2A+3C → two children free, one paid (3 seats) |
+
+**Track B — config → portal propagation & validation gaps** (`specs/backoffice`, `specs/propagation`):
+
+| ID | Spec | What it proves |
+|----|------|----------------|
+| PB-1 | `pb-config-propagation` | FX-rate change propagates live to portal USD pricing |
+| PB-2 / PB-2b | `pb-config-propagation` | seat-class base-price change propagates live; `basePrice` field drives the fare |
+| PB-4 | `pb-config-propagation` | station added in backoffice appears in the portal station list |
+| PB-7 | `config-validation` | 🔴 promo created with backoffice UI field names is inert (field-name mismatch) |
+| PB-10 | `pb-config-propagation` | ✅ deleting an FX rate now FAILS CLOSED (no priced fare) instead of a silent 1.0 collapse (M-5/H-2 fixed & guarded) |
+| BC-7 | `pb-config-propagation` | ✅ negative seat-class base price now REJECTED (400, DTO `@Min(0)`) (M-1 fixed & guarded) |
+| BC-8 | `config-validation` | ✅ promo over 100% now REJECTED (400, DTO `@Max(100)`) (M-2 fixed & guarded) |
+| BC-9 | `config-validation` | ✅ negative seat-hold duration now REJECTED (400, whitelisted typed `/config` DTO) (M-3 fixed & guarded) |
+| BC-10 | `config-validation` | 🔴 schedule with a past departure accepted (M-4) |
+| BC-11 | `pb-config-propagation` | ✅ non-admin passenger now FORBIDDEN (403) from FX writes; admin still allowed (C-8 fixed & guarded) |
+
+### Deferred (documented, not silently omitted)
+
+- **UA-7** (round-trip berth) — `specs/portal/ua7-berth.spec.ts` is `test.skip` with the reason: needs
+  a bed CoachType + reverse-leg pricing, both backend prerequisites (see UA-6 for the reverse-leg gap).
+- **UA-9 / UA-10 / UA-12 / UA-17** — the matrix moves these to the API-level harness (over-100% /
+  over-subtotal promos, loyalty over-redeem, DJF×promo negative total): no reachable browser path
+  (server clamps `reviewedTotalMinor` ≥ 0; the portal never calls the loyalty/fare-quote path).
+- **PB-3/5/6/8/9, BC-1…BC-6** — additional config surfaces and delete-referenced/mid-flight/staleness
+  variations of the finding classes already covered above; the matrix marks several as deferrable.
+
+**Gateway settlement:** the real telebirr gateway is unreachable in the test env (`/payments/initiate`
+502s), so gateway rows (UA-3, UA-15) create the booking through the real browser flow and then inject
+settlement via `POST /internal/payments/mark-paid` — exactly the matrix's settlement-injection plan.
+
+Portal testids used: `result-select-btn`, `coach-option`, `continue-passenger-details`,
+`pay-method-{TYPE}`. Everything else (passengers form + DOB modal, seats auto-assign, review, payment)
+is driven via name/placeholder/role selectors — no further source edits were needed.
+
+**Seed note:** `Passenger.id` is set EQUAL to the IAM user id — see the comment in `seed-ui.ts`
+(`UI_IDS.passenger`) and the SUSPECTED FINDING below. Each coach seeds 48 seats so a full serial run
+never exhausts availability across specs.
+
+## Suspected finding (surfaced while building UA-1)
+
+`POST /bookings` (authenticated) overrides `passengerId` with the JWT user id
+(`bookings.controller.ts:528-532`, "never trust the request body"). The service only resolves an
+iamUserId → Passenger when it is **non-UUID** (`bookings.service.ts:773`). IAM user ids are UUIDs, so
+the resolver never fires and `booking.create` uses the iamUserId directly as `passengerId` → FK
+violation unless `Passenger.id == iamUserId`. This is why the seed aligns them. **Verify against a
+real IAM-authenticated booking** — if `req.user.id` is genuinely the iamUserId in production,
+authenticated portal bookings may be broken (guest path unaffected). Candidate for `docs/ISSUES.md`.
+
+## Prerequisites — the running stack
+
+The suite drives a live stack. `global-setup.ts` seeds + mints auth, but assumes the apps are
+already up. Bring them up once (leave running across test runs):
+
+```bash
+# 1. Infra: test Postgres (5544) + RabbitMQ (5672, payment vhost)
+bash e2e/prepare.sh              # postgres + migrations
+docker compose -f e2e/docker-compose.yml up -d rabbitmq-e2e
+
+# 2. Build the shared types package (nest build needs the dist)
+pnpm --filter @edr/types build
+
+# 3. passenger-api on :4000 against the 5544 DB, with org+staff seeding on
+#    (apps/edr-passenger-api/.env sets DATABASE_URL=…5544, PORT=4000,
+#     RABBITMQ_ENABLED=false, FAYDA_ENABLED=false, SEED_EDR_PASSENGER_ORG=true,
+#     SEED_PASSENGER_STAFF=true, DEFAULT_PASSWORD=Test@1234)
+( cd apps/edr-passenger-api && pnpm dev )        # background
+
+# 4. Web apps (each has .env.local → NEXT_PUBLIC_API_URL=http://localhost:4000)
+( cd apps/edr-passenger-web/portal && pnpm dev )      # :5174, background
+( cd apps/edr-passenger-web/backoffice && pnpm dev )  # :5184, background
+```
+
+> `playwright.config.ts` now declares a `webServer` block that auto-boots api/portal/backoffice and
+> **reuses** them if already running, so steps 3–4 are optional in local dev. Gateway rows settle via
+> the internal `mark-paid` endpoint, so `apps/edr-payment-api` (:3003) is **not** required.
+
+## Run
+
+One command (infra → build → boot → seed+auth → run → open report):
+
+```bash
+bash e2e-ui/run.sh                                  # all projects; args pass through to playwright
+bash e2e-ui/run.sh --headed                         # watch it in a real browser
+SLOWMO=500 bash e2e-ui/run.sh --headed              # slow every action by 500ms
+bash e2e-ui/run.sh --project=portal ua4             # one project / filter by title
+```
+
+Or, against an already-running stack:
+
+```bash
+pnpm test:e2e:ui                                    # all projects
+pnpm test:e2e:ui -- --project=guest --project=backoffice   # smoke only
+```
+
+HTML report → `e2e-ui-report/index.html`.
+
+## Layout
+
+```
+e2e-ui/
+  playwright.config.ts     projects: portal (passenger auth), guest (none),
+                           backoffice (staff auth), propagation (cross-app)
+  global-setup.ts          seeds test DB (seed-ui.ts) + mints staff.json via real /login
+  fixtures/
+    data.ts                station IDs, sample depart date, results deep-link helper
+    storage/staff.json      generated staff storageState (gitignored)
+  specs/{guest,portal,backoffice,propagation}/*.spec.ts
+```
+
+Seed lives with the API harness: `apps/edr-passenger-api/test/fixtures/seed-ui.ts` (extends
+`seed-core.ts` with a bookable Train/Schedule/Coach/Seats, enabled PaymentMethods WALLET+TELEBIRR,
+promos, funded wallet). Run standalone: `npx ts-node test/fixtures/seed-ui.ts`.
+
+## Auth model (grounded in the app)
+
+- **Portal (passenger)**: `localStorage.auth_token` only, no server gate. (passenger storageState is
+  a Phase 3 item — smoke uses the `guest` project.)
+- **Backoffice (staff)**: middleware requires the `auth_token` **cookie**; API guards check the
+  session's permissions. `global-setup` logs in as the seeded `passenger.admin@edr.local` through
+  the real `/login` UI and snapshots both. No hand-crafted tokens.
