<objective>
Build subscriber portal authentication (login via account number) and read-only account/billing/payment endpoints scoped to the logged-in subscriber.

Purpose: PORT-01, PORT-02, PORT-04 — subscribers can self-serve to view their bills, payments, and plan details.
Output: Portal auth provider, PortalService, portal API routes, passing tests.
</objective>

<task type="auto">
  <name>Task 1: Portal authentication — subscriber login via account number</name>
  <files>src/lib/auth-options.ts, src/middleware.ts, prisma/schema.prisma</files>
  <action>
**Schema change (prisma/schema.prisma):**
Add a `passwordHash` field to the Subscriber model:
```
passwordHash  String?
```
This is nullable because existing subscribers may not have portal access yet. Only subscribers with a passwordHash can log in.

Run `npx prisma db push` to apply (same pattern as all prior schema changes).

**Auth options (src/lib/auth-options.ts):**
Add a SECOND CredentialsProvider to the providers array with id `"portal-credentials"`:
- Accepts `{ accountNumber, password, tenantId }` (tenantId is required to scope the lookup — subscriber account numbers are unique per tenant)
- Looks up Subscriber by `@@unique([tenantId, accountNumber])` where passwordHash is not null
- Verifies password with bcrypt.compare
- On success, returns a user-shaped object with:
  - `id`: subscriber.id
  - `email`: subscriber.email || subscriber.accountNumber (NextAuth requires email field)
  - `tenantId`: subscriber.tenantId
  - `roles`: [Role.CLIENT]
  - `isSuperAdmin`: false
  - `firstName`: subscriber.firstName
  - `lastName`: subscriber.lastName
  - Plus a custom field `subscriberId`: subscriber.id (to distinguish portal users from staff users)
- The JWT callback must persist `subscriberId` into the token
- The session callback must expose `subscriberId` on session.user

**Important:** Keep the existing staff CredentialsProvider unchanged. The portal provider is additive.

**NextAuth type extension (src/types/next-auth.d.ts):**
Add `subscriberId?: string` to the Session user interface and JWT interface.

**Middleware (src/middleware.ts):**
Add `/portal/login` to the matcher exclusion pattern so unauthenticated subscribers can reach the login page. Pattern update: add `portal/login` to the negative lookahead alongside `login|signup`.

Also exclude `/api/portal/auth` from the auth requirement so the portal login API call works.
  </action>
  <verify>`npx prisma db push` succeeds; `npx tsc --noEmit` compiles without errors</verify>
  <done>Subscriber can authenticate via account number + password through NextAuth portal-credentials provider; JWT carries subscriberId; middleware allows portal login page access</done>

  <name>Task 2: PortalService and portal API endpoints with tests</name>
  <files>src/lib/services/portal-service.ts, src/app/api/portal/account/route.ts, src/app/api/portal/invoices/route.ts, src/app/api/portal/payments/route.ts, src/lib/__tests__/portal-service.test.ts</files>
  <action>
**PortalService (src/lib/services/portal-service.ts):**
All methods take a TenantPrismaClient and subscriberId — data is ALWAYS scoped to that single subscriber.

1. **getPortalAccount(db, subscriberId)** — Returns subscriber profile with plan details:
   - Query Subscriber with include: { servicePlan: true }
   - Return: { accountNumber, firstName, lastName, email, phone, address, status, activatedAt, plan: { name, speed, monthlyPrice, billingType }, creditBalance, billingDay }

2. **getPortalInvoices(db, subscriberId, options?: { page, limit })** — Returns paginated invoices:
   - Query Invoice where subscriberId, ordered by periodStart DESC
   - Include invoiceLines for detail
   - Return: { invoices: Invoice[], total: number, page: number }
   - Default: page=1, limit=10

3. **getPortalPayments(db, subscriberId, options?: { page, limit })** — Returns paginated payment history:
   - Query Payment where subscriberId, ordered by createdAt DESC
   - Return: { payments: Payment[], total: number, page: number }
   - Default: page=1, limit=20

**API Routes:**

All portal API routes use a custom `withPortalAuth` helper (create it in the same file or a shared portal middleware file). This helper:
- Gets the session via getCurrentUser()
- Checks session.user.subscriberId exists (must be a portal user, not staff)
- Returns 401 if no session, 403 if not a portal user
- Passes subscriberId to the handler

**GET /api/portal/account** — calls getPortalAccount, returns subscriber profile + plan
**GET /api/portal/invoices** — calls getPortalInvoices with pagination from query params
**GET /api/portal/payments** — calls getPortalPayments with pagination from query params

**Integration Tests (src/lib/__tests__/portal-service.test.ts):**
Setup: Create tenant, create subscriber with passwordHash (use bcrypt.hashSync), create service plan, generate invoices, record payments.

Tests (minimum 5):
1. `getPortalAccount returns subscriber with plan details` — verify all fields present
2. `getPortalInvoices returns paginated invoices` — create 3 invoices, request page 1 limit 2, verify pagination
3. `getPortalPayments returns paginated payment history` — create 2 payments, verify list
4. `getPortalAccount scoped to subscriberId only` — create 2 subscribers, verify each can only see their own data
5. `getPortalInvoices includes invoice line items` — verify invoiceLines are included

Cleanup: payments -> paymentAllocations -> invoiceLines -> invoices -> journalEntryLines -> null reversesEntryId -> journalEntries -> subscribers -> servicePlans -> tenantSettings -> accountingPeriods -> accounts -> users -> tenant
  </action>
  <verify>`npx vitest run src/lib/__tests__/portal-service.test.ts` — all tests pass</verify>
  <done>Portal endpoints return subscriber-scoped account, invoice, and payment data; 5+ tests pass; PORT-01, PORT-02, PORT-04 satisfied</done>
</task>

- `npx prisma db push` applies Subscriber.passwordHash
- `npx tsc --noEmit` passes
- `npx vitest run src/lib/__tests__/portal-service.test.ts` — all tests pass
- Portal auth uses account number (not email) per CONTEXT.md decision
</verification>

<success_criteria>
- Subscriber authenticates via account number + password
- Portal API endpoints return only the logged-in subscriber's data
- Account overview includes plan details, balance, and billing day
- Invoice and payment history are paginated
- PORT-01, PORT-02, PORT-04 requirements satisfied
