-# ANALYST Agent Rule
-
-This rule is triggered when the user types `@analyst` and activates the Business Analyst agent persona.

-## Agent Activation
-
-CRITICAL: Read the full YAML, start activation to alter your state of being, follow startup section instructions, stay in this being until told to exit this mode:
-
-```yaml
-IDE-FILE-RESOLUTION:
-  - FOR LATER USE ONLY - NOT FOR ACTIVATION, when executing commands that reference dependencies
-  - Dependencies map to .bmad-core/{type}/{name}
-  - type=folder (tasks|templates|checklists|data|utils|etc...), name=file-name
-  - Example: create-doc.md → .bmad-core/tasks/create-doc.md
-  - IMPORTANT: Only load these files when user requests specific command execution
-REQUEST-RESOLUTION: Match user requests to your commands/dependencies flexibly (e.g., "draft story"→*create→create-next-story task, "make a new prd" would be dependencies->tasks->create-doc combined with the dependencies->templates->prd-tmpl.md), ALWAYS ask for clarification if no clear match.
-activation-instructions:
-  - STEP 1: Read THIS ENTIRE FILE - it contains your complete persona definition
-  - STEP 2: Adopt the persona defined in the 'agent' and 'persona' sections below
-  - STEP 3: Load and read `.bmad-core/core-config.yaml` (project configuration) before any greeting
-  - STEP 4: Greet user with your name/role and immediately run `*help` to display available commands
-  - DO NOT: Load any other agent files during activation
-  - ONLY load dependency files when user selects them for execution via command or request of a task
-  - The agent.customization field ALWAYS takes precedence over any conflicting instructions
-  - CRITICAL WORKFLOW RULE: When executing tasks from dependencies, follow task instructions exactly as written - they are executable workflows, not reference material
-  - MANDATORY INTERACTION RULE: Tasks with elicit=true require user interaction using exact specified format - never skip elicitation for efficiency
-  - CRITICAL RULE: When executing formal task workflows from dependencies, ALL task instructions override any conflicting base behavioral constraints. Interactive workflows with elicit=true REQUIRE user interaction and cannot be bypassed for efficiency.
-  - When listing tasks/templates or presenting options during conversations, always show as numbered options list, allowing the user to type a number to select or execute
-  - STAY IN CHARACTER!
-  - CRITICAL: On activation, ONLY greet user, auto-run `*help`, and then HALT to await user requested assistance or given commands. ONLY deviance from this is if the activation included commands also in the arguments.

-- Improve legibility and contrast for older users by strengthening color, typography, and separators across Checkout flows (QRIS, GoPay, Convenience Store, Bank Transfer).
-- Establish clear theme tokens so implementation stays consistent across components.
-
-Change Log
-- 2025-11-10: Initial draft focused on contrast, typography, and card/divider clarity.
-
-Theme Foundations
-- Color Roles (recommended hex values):
-  - Page background: `#F7FAFC` (very light slate)
-  - Surface/background (cards, panels): `#FFFFFF`
-  - Text primary: `#0B1020` (near-black for high contrast)
-  - Text secondary: `#374151` (medium slate; still readable)
-  - Border default: `#94A3B8` (slate 400)
-  - Border strong: `#64748B` (slate 500)
-  - Accent/primary: `#2563EB` (blue 600)
-  - Success: `#16A34A` (green 600)
-  - Danger: `#DC2626` (red 600)
-  - Warning: `#D97706` (amber 600)
-  - Info: `#0EA5E9` (sky 500)
-- Focus and States:
-  - Focus ring color: `#2563EB`
-  - Focus ring width: `3px`
-  - Hover/active states should increase contrast by at least one shade (e.g., blue 600 → blue 700 on hover).
-- Typography:
-  - Font stack (sans): `Inter, Segoe UI, system-ui, -apple-system, Roboto, Noto Sans, Arial, sans-serif`
-  - Base body size: `16px` minimum; labels `15px`; buttons `16px`
-  - Headings: `H4 20px`, `H3 24px`, `H2 28px` (line-height ~1.3)
-  - Body line-height: `1.5` for readability
-  - Avoid ultra-light weights; prefer `400–600` for body/labels
-- Separators and Borders:
-  - Default divider: `1.5px` `#94A3B8`
-  - Strong divider: `2px` `#64748B` for section breaks and card boundaries
-  - Cards: visible 2px border, subtle shadow `0 1px 2px rgba(0,0,0,0.08)`
-- Spacing Scale (base):
-  - `4px` units; common spacing: `8/12/16/24/32px`
-  - Minimum interior padding for cards: `16–24px`
-
-Accessibility Standards
-- Contrast:
-  - Normal text contrast ≥ `4.5:1`; large text (≥18px) ≥ `3:1`
-  - Verify accent on white and on light surfaces meets ratios
-- Touch Targets:
-  - Minimum hit area: `44x44px` for interactive elements
-  - Minimum tap spacing: `8px` around grouped actions
-- Focus & Keyboard:
-  - Always-visible focus outline with `3px` ring in accent color
-  - Skip links available on long forms
-- Motion & Feedback:
-  - Respect reduced motion; avoid aggressive animations
-  - Provide textual or icon feedback in addition to color changes
-
-Component Guidance
-- Cards/Panels:
-  - Use strong border (`2px #64748B`) for outer frame when content density is high
-  - Title uses `H4/H3` with primary text color; subtitle uses secondary
-  - Interior dividers use default border (`1.5px #94A3B8`)
-- Buttons:
-  - Primary: solid `#2563EB` with white text; hover `#1D4ED8`
-  - Secondary: outline with strong border and primary text
-  - Disabled: `#CBD5E1` background, `#64748B` text; maintain contrast
-  - Focus: `3px` accent ring outside button
-- Inputs:
-  - Label size `15–16px` and primary text color; never rely on placeholder as label
-  - Field border default; on focus switch to strong border and accent ring
-  - Error state uses danger color and text hint; icon optional
-- Lists/Selection (e.g., store selection):
-  - Row height ≥ `48px`; radio/checkbox minimum `24px`
-  - Selected state uses strong border and light accent background (`blue-50`)
-
-Implementation Notes
-- CSS Variables (define once):
-  ```css
-  :root {
-    --color-bg-page: #F7FAFC;
-    --color-bg-surface: #FFFFFF;
-    --color-text-primary: #0B1020;
-    --color-text-secondary: #374151;
-    --color-border-default: #94A3B8;
-    --color-border-strong: #64748B;
-    --color-accent: #2563EB;
-    --color-success: #16A34A;
-    --color-danger: #DC2626;
-    --color-warning: #D97706;
-    --color-info: #0EA5E9;
-    --focus-ring-width: 3px;
-    --focus-ring-color: #2563EB;
-    --shadow-card: 0 1px 2px rgba(0,0,0,0.08);
-    --border-width-default: 1.5px;
-    --border-width-strong: 2px;
-    --font-family-sans: Inter, Segoe UI, system-ui, -apple-system, Roboto, Noto Sans, Arial, sans-serif;
-    --font-size-body: 16px;
-    --font-size-label: 15px;
-    --font-size-button: 16px;
-    --font-size-h4: 20px;
-    --font-size-h3: 24px;
-    --font-size-h2: 28px;
-    --line-height-body: 1.5;
-  }
-  ```
-- Tailwind Theme (high-level):
-  - Map CSS variables to custom colors via CSS-in-JS or add a custom palette in `tailwind.config.*` aligned to the hex values above
-  - Increase `ringWidth` default to `3`, add `ringColor` for focus, and define `borderWidth` scale with `1.5` and `2`
-- Component Application:
-  - Replace `border-gray-200/300` with `border-[#94A3B8]` for dividers
-  - Use `border-[2px]` + `border-[#64748B]` for card frames when needed
-  - Set `text-[#0B1020]` as default text and avoid pure black for softer rendering
-
-Validation Checklist
-- Body text ≥16px and headings per spec
-- Divider visibility validated on standard laptop and low-contrast displays
-- All critical actions meet contrast and focus outline requirements
-- Component states (hover, active, disabled, error) meet color and contrast standards
- 
-Instruksi Langkah Pembayaran
-- Tujuan: Menyajikan cara bayar yang jelas tanpa Step Wizard. Fokus pada daftar langkah ringkas untuk tiap metode (QRIS, GoPay, Transfer Bank via Mobile/Internet Banking/ATM, Convenience Store).
-- Prinsip Penyajian:
-  - Judul panel: "Cara Bayar" + nama metode/bank (mis. "Cara Bayar: BCA Mobile", "Cara Bayar: ATM BNI", "Cara Bayar: QRIS").
-  - Gunakan daftar bernomor (1., 2., 3.) dengan jarak antar langkah `12–16px` dan body `16–18px`.
-  - Kalimat singkat, langsung, maksimal ±100 karakter per langkah.
-  - Gunakan teks primer `#0B1020`; hindari abu-abu pucat untuk keterbacaan.
-  - Divider opsional antar kelompok langkah memakai border default `#94A3B8`.
-  - Ikon langkah opsional; jangan menggantikan teks instruksi.
-

-# Integrasi Midtrans Credit Card (Core API + 3DS)
-
-Dokumen ini merangkum integrasi kartu kredit/debit menggunakan Midtrans Core API dan 3DS, sebagaimana diimplementasikan dalam proyek ini.
-
-## Prasyarat
-
-- Akun Midtrans Sandbox dengan `Client Key` dan `Server Key`.
-- Dependensi backend: `express`, `cors`, `dotenv`, `midtrans-client` terpasang.
-- Dependensi frontend: loader skrip `MidtransNew3ds` via util `midtrans3ds.ts`.
-
-## Konfigurasi Environment
-
-- Frontend (`.env.local`):
-  - `VITE_MIDTRANS_CLIENT_KEY="<client key sandbox>"`
-  - `VITE_MIDTRANS_ENV="sandbox"` atau `production`
-  - `VITE_API_BASE_URL="http://localhost:8000/api"`
-
-- Backend (`.env`):
-  - `MIDTRANS_SERVER_KEY="<server key sandbox>"`
-  - `MIDTRANS_CLIENT_KEY="<client key sandbox>"` (opsional, untuk referensi log)
-  - `MIDTRANS_IS_PRODUCTION=false`
-
-## Alur Frontend
-
-1. Memuat skrip `MidtransNew3ds` dinamis via `ensureMidtrans3ds()` saat mount `CardPanel`.
-2. Mengambil input pengguna: `card_number`, `expiry (MM/YY)`, `cvv`.
-3. Validasi minimal: panjang nomor kartu (13–19), bulan 01–12, CVV 3–4.
-4. Tokenisasi kartu: `getCardToken({ card_number, card_exp_month, card_exp_year, card_cvv })`.
-5. Mengirim `token_id` ke backend melalui `postCharge` dengan payload:
-
-```json
-{
-  "payment_type": "credit_card",
-  "transaction_details": { "order_id": "<orderId>", "gross_amount": <amount> },
-  "credit_card": { "token_id": "<tokenId>", "authentication": true, "save_token_id": true|false }
-}
-```
-
-6. Menangani 3DS: jika respons berisi `redirect_url`, panggil `authenticate3ds(redirect_url)` (SDK akan mengarahkan ke challenge 3DS dan kembali lagi).
-7. Mengaktifkan tombol "Cek Status Pembayaran" ketika charge sukses (`capture/settlement`) atau setelah 3DS dimulai (state `locked`).
-
-## Alur Backend
-
-- Endpoint `POST /api/payments/charge`
-  - Menggunakan `midtrans-client` CoreApi.
-  - Meneruskan payload dari frontend, memastikan `credit_card.authentication = true`.
-  - Mengembalikan respons Midtrans termasuk `transaction_status` dan `redirect_url` jika 3DS diperlukan.
-
-- Endpoint `GET /api/payments/:orderId/status`
-  - Memanggil `core.status(orderId)` untuk mendapatkan status terbaru transaksi.
-  - Digunakan oleh UI untuk halaman status pembayaran.
-
-## Menjalankan Proyek
-
-- Backend: `npm run server` (default pada `http://localhost:8000`).
-- Frontend: `npm run dev` lalu buka `http://localhost:5173` (atau port alternatif yang dipilih Vite).
-
-Pastikan `VITE_API_BASE_URL` menunjuk ke `http://localhost:8000/api` agar frontend memanggil backend yang tepat.
-
-## Catatan Keamanan
-
-- Jangan pernah mengekspos `MIDTRANS_SERVER_KEY` di frontend atau file publik.
-- Token kartu (`token_id`) hanya diproduksi di frontend melalui `MidtransNew3ds` dan dikirim ke backend yang memegang `serverKey`.
-
-## Referensi
-
-- Midtrans Docs: Credit Card with 3DS (Core API).
-- Contoh: `coreApiSimpleExample.js` untuk pola panggilan Core API.
-
-## Webhook & ERP Callback
-
-- Endpoint webhook Midtrans: `POST /api/payments/webhook` (server Express)
-  - Verifikasi `signature_key = sha512(order_id + status_code + gross_amount + MIDTRANS_SERVER_KEY)`.
-  - Menerima notifikasi status dan menandai sukses untuk `settlement` (umum) atau `capture` dengan `fraud_status=accept` (kartu).
-- ERP Notification (opsional, via env feature flag):
-  - Konfigurasi `.env` backend:
-    - `ERP_NOTIFICATION_URL="https://apibackend.erpskrip.id/paymentnotification/"`
-    - `ERP_CLIENT_ID="<dari ERP>"`
-    - `ERP_MERCANT_ID="<dari ERP>"`
-    - `ERP_ENABLE_NOTIF=true`
-  - Payload dikirim saat sukses:
-    ```json
-    {
-      "data": {
-        "mercant_id": "<id>",
-        "status_code": "200",
-        "nominal": "<gross_amount>",
-        "client_id": "<id>"
-      },
-      "signature": "sha512(mercant_id + status_code + nominal + client_id)"
-    }
-    ```

-# Panduan QA End-to-End: Payment Link
-
-Dokumen ini menjelaskan alur end-to-end Payment Link yang tersedia di proyek, mencakup konfigurasi, endpoint backend, format token, langkah QA dengan contoh request, hingga troubleshooting dan integrasi frontend.
-
-## Ringkasan Alur
-- ERP/eksternal membuat Payment Link via `POST /createtransaksi` dan menerima `url` serta `token`.
-- Frontend membuka halaman `Pay` di route `pay/:token`, lalu me-resolve token via `GET /api/payment-links/:token`.
-- Pengguna memilih metode pembayaran (sesuai `allowed_methods` dan toggle runtime), kemudian frontend memanggil `POST /api/payments/charge`.
-- Status pembayaran dapat dicek via `GET /api/payments/:orderId/status` dan disinkronkan via webhook `POST /api/payments/webhook`.
-
-## Prasyarat & Konfigurasi
-- Backend: jalankan `node server/index.cjs` (default port `8000`).
-- Frontend: jalankan `npm run dev` (contoh dev port: `5175`).
-- Penyesuaian environment penting:
-  - `EXTERNAL_API_KEY`: API Key luar untuk `POST /createtransaksi`. Jika tidak diset, di dev akan diizinkan tanpa key.
-  - `PAYMENT_LINK_SECRET`: secret untuk penandatanganan token Payment Link (HMAC SHA-256). Default dev: `dev-secret`.
-  - `PAYMENT_LINK_TTL_MINUTES`: waktu kedaluwarsa token (default: `30`).
-  - `PAYMENT_LINK_BASE`: base URL untuk halaman `Pay` (default: `http://localhost:5174/pay`). Sesuaikan ke port frontend yang aktif (misal `http://localhost:5175/pay`).
-  - `PORT`: port backend (default: `8000`).
-  - `ERP_NOTIFICATION_URL`, `ERP_CLIENT_ID`, `ERP_MERCANT_ID`, `ERP_ENABLE_NOTIF`: konfigurasi notifikasi ERP saat settlement.
-  - Midtrans keys: Server Key dan Client Key harus tersedia untuk charge/status.
-  - Frontend env: `VITE_API_BASE_URL` (contoh: `http://localhost:8000/api`), `VITE_MIDTRANS_CLIENT_KEY`.
-
-## Endpoint Backend
-- `POST /createtransaksi`
-  - Header: `X-API-KEY` (opsional di dev jika `EXTERNAL_API_KEY` tidak diset).
-  - Body: `{ item_id | order_id, nominal, customer?, allowed_methods? }`
-  - Respon: `{ url, token, order_id, nominal, expire_at }`
-  - Error: `UNAUTHORIZED`, `BAD_REQUEST`, `ORDER_COMPLETED`, `ORDER_ACTIVE`, `CREATE_ERROR`.
-
-- `GET /api/payment-links/:token`
-  - Respon: `{ order_id, nominal, customer?, expire_at?, allowed_methods? }`
-  - Error: `410 TOKEN_EXPIRED`, `400 INVALID_*` (di dev ada fallback payload jika token invalid).
-
-- `POST /api/payments/charge`
-  - Body: payload Midtrans (contoh di bawah). Diblokir jika method dimatikan oleh runtime toggles.
-  - Error: `PAYMENT_TYPE_DISABLED`, `CHARGE_ERROR`.
-
-- `GET /api/payments/:orderId/status`
-  - Respon: pass-through dari Midtrans (transaction status, VA, dll.).
-
-- `POST /api/payments/webhook`
-  - Verifikasi signature: `sha512(orderId + statusCode + grossAmount + serverKey)`.
-  - Pada sukses (settlement atau capture+accept untuk kartu), backend kirim notifikasi ke ERP (jika diaktifkan) dan menandai order sebagai completed.
-
-- `GET /api/health`, `GET/POST /api/config`
-  - Health: cek ketersediaan key dan environment.
-  - Config: baca/ubah toggles (dev-only untuk `POST`).
-
-## Format Token Payment Link
-- Token adalah `base64url(JSON)` dengan fields minimal: `{ v, order_id, nominal, expire_at, sig, customer?, allowed_methods? }`.
-- `sig` adalah HMAC SHA-256 dari string kanonik: `"order_id|nominal|expire_at"` menggunakan `PAYMENT_LINK_SECRET`.
-
-## Langkah QA (Contoh)
-
-1) Buat Payment Link
-
-PowerShell (Windows):
-
-```powershell
-$body = @{
-  item_id = 'INV-PL-001';
-  nominal = 150000;
-  customer = @{ name='QA Tester'; phone='081234567890'; email='qa@example.com' };
-  allowed_methods = @('bank_transfer','cstore','gopay','credit_card')
-} | ConvertTo-Json -Depth 5;
-
-Invoke-RestMethod -Method POST -Uri 'http://localhost:8000/createtransaksi' -ContentType 'application/json' -Body $body | ConvertTo-Json -Depth 5
-```
-
-curl:
-
-```bash
-curl -X POST http://localhost:8000/createtransaksi \
-  -H 'Content-Type: application/json' \
-  -H 'X-API-KEY: <jika-diperlukan>' \
-  -d '{
-    "item_id":"INV-PL-001",
-    "nominal":150000,
-    "customer": {"name":"QA Tester","phone":"081234567890","email":"qa@example.com"},
-    "allowed_methods":["bank_transfer","cstore","gopay","credit_card"]
-  }'
-```
-
-2) Resolve Token
-
-```powershell
-Invoke-RestMethod -Method GET -Uri "http://localhost:8000/api/payment-links/<token>" | ConvertTo-Json -Depth 5
-```
-
-3) Buka Halaman Pay
-
-- Buka `http://localhost:5175/pay/<token>` (sesuaikan `PAYMENT_LINK_BASE` dengan port frontend).
-- Periksa daftar metode, panel, serta batasan dari `allowed_methods` dan runtime toggles.
-
-4) Charge Bank Transfer (BCA)
-
-```powershell
-$bt = @{
-  payment_type = 'bank_transfer';
-  transaction_details = @{ order_id = 'INV-PL-001'; gross_amount = 150000 };
-  bank_transfer = @{ bank = 'bca' }
-} | ConvertTo-Json -Depth 5;
-
-Invoke-RestMethod -Method POST -Uri 'http://localhost:8000/api/payments/charge' -ContentType 'application/json' -Body $bt | ConvertTo-Json -Depth 5
-```
-
-5) Charge GoPay/QR (opsional)
-
-```powershell
-$qr = @{
-  payment_type = 'gopay';
-  transaction_details = @{ order_id = 'INV-PL-001'; gross_amount = 150000 };
-  gopay = @{ enable_qr = $true }
-} | ConvertTo-Json -Depth 5;
-
-Invoke-RestMethod -Method POST -Uri 'http://localhost:8000/api/payments/charge' -ContentType 'application/json' -Body $qr | ConvertTo-Json -Depth 5
-```
-
-Catatan: Bila `400 Bad Request`, cek konfigurasi akun sandbox dan parameter GoPay/QRIS (lihat bagian troubleshooting).
-
-6) Status Check
-
-```powershell
-Invoke-RestMethod -Method GET -Uri 'http://localhost:8000/api/payments/INV-PL-001/status' | ConvertTo-Json -Depth 5
-```
-
-7) Webhook (uji manual)
-
-Untuk uji manual, kirim payload menyerupai notifikasi Midtrans dengan `signature_key` yang valid. Signature dihitung:
-
-```js
-// Node.js contoh perhitungan signature
-const crypto = require('crypto')
-function computeMidtransSignature(orderId, statusCode, grossAmount, secretKey) {
-  const raw = String(orderId) + String(statusCode) + String(grossAmount) + String(secretKey)
-  return crypto.createHash('sha512').update(raw).digest('hex')
-}
-```
-
-Kemudian `POST` ke `http://localhost:8000/api/payments/webhook` dengan body berisi fields Midtrans (order_id, status_code, gross_amount, signature_key, dll.).
-
-## Troubleshooting
-- Frontend tidak sesuai `PAYMENT_LINK_BASE` (5174 vs 5175): set `PAYMENT_LINK_BASE=http://localhost:5175/pay` di backend agar URL link mengarah ke port yang benar.
-- `400 Bad Request` untuk GoPay/QR:
-  - Pastikan `gopay` payload memenuhi kebutuhan sandbox (mis. `enable_qr`, kadang perlu `qr_black_white`, atau `callback_url`).
-  - Periksa toggles runtime (`/api/config`) dan ketersediaan Midtrans keys.
-  - Beberapa merchant sandbox memiliki batasan; rujuk dokumentasi Midtrans untuk parameter terbaru.
-- `UNAUTHORIZED` saat `createtransaksi`: set header `X-API-KEY` sesuai `EXTERNAL_API_KEY` jika dikonfigurasi.
-- `ORDER_ACTIVE` atau `ORDER_COMPLETED`: backend menjaga `activeOrders` dan `notifiedOrders` untuk mencegah duplikasi; tunggu TTL atau gunakan order baru.
-
-## Integrasi Frontend
-- Route: `pay/:token` (lihat `src/app/router.tsx`).
-- Resolver: `getPaymentLinkPayload(token)` (lihat `src/services/api.ts`).
-- Toggle & Allowed Methods: `PayPage` menggabungkan `runtimeCfg.paymentToggles` dengan `allowed_methods`. Kunci metode: `bank_transfer`, `credit_card`, `gopay`, `cstore`, `cpay`.
-
-## Notifikasi ERP
-- Di settlement sukses, backend menghitung signature ERP (`sha512`) dan mengirim payload ke `ERP_NOTIFICATION_URL` jika `ERP_ENABLE_NOTIF=true` dan konfigurasi lengkap.
-
-## Postman Collection
-- Anda dapat mengimpor koleksi: `docs/qa/payment-link.postman_collection.json` untuk mencoba endpoint di atas.
-
-## Pengujian via Postman (Langkah Lengkap)
-
-### 1) Import & Setup Environment
-- Import koleksi: `docs/qa/payment-link.postman_collection.json`.
-- Buat Environment (mis. `Midtrans-CIFO-Local`) dengan variabel:
-  - `baseUrl`: `http://localhost:8000`
-  - `paymentLinkBase`: `http://localhost:5175/pay` (sesuaikan port frontend)
-  - `externalApiKey`: kosong atau set sesuai `EXTERNAL_API_KEY` (jika diaktifkan)
-  - `token`: kosong (akan diisi dari respon create)
-  - `order_id`: kosong (akan diisi dari respon create)
-
-Catatan: Koleksi memakai variabel ini pada URL/body. Pastikan environment terpilih saat menjalankan request.
-
-### 2) Jalankan Koleksi (Urutan Dasar)
-1. `1) Create Transaction`
-   - Body default: `item_id`, `nominal`, `customer`, `allowed_methods`.
-   - Jika `EXTERNAL_API_KEY` aktif, pastikan header `X-API-KEY: {{externalApiKey}}` terisi.
-2. `2) Resolve Token`
-   - Memakai `{{token}}` dari langkah 1.
-3. `3) Charge - Bank Transfer (BCA)` atau `3) Charge - CStore (Indomaret)`
-   - Memakai `{{order_id}}` dari langkah 1.
-4. `4) Payment Status`
-   - Memakai `{{order_id}}` untuk cek status.
-
-### 3) Skrip Test untuk Otomatis Mengisi Variabel
-Tambahkan skrip berikut pada tab `Tests` di request `1) Create Transaction` agar `token`, `order_id`, dan `paymentLinkUrl` otomatis tersimpan ke variabel koleksi:
-
-```javascript
-// Tests: 1) Create Transaction
-pm.test('Create returns token and url', function () {
-  pm.response.to.have.status(200);
-  const json = pm.response.json();
-  pm.expect(json).to.have.property('token');
-  pm.expect(json).to.have.property('url');
-  pm.expect(json).to.have.property('order_id');
-});
-
-const res = pm.response.json();
-pm.collectionVariables.set('token', res.token);
-pm.collectionVariables.set('order_id', res.order_id);
-pm.collectionVariables.set('paymentLinkUrl', res.url);
-```
-
-Tambahkan skrip sederhana di `2) Resolve Token` untuk validasi payload:
-
-```javascript
-pm.test('Resolve returns payload fields', function () {
-  pm.response.to.have.status(200);
-  const json = pm.response.json();
-  pm.expect(json).to.have.property('order_id');
-  pm.expect(json).to.have.property('nominal');
-});
-```
-
-Di `3) Charge - Bank Transfer (BCA)`, tambahkan assert dasar:
-
-```javascript
-pm.test('Charge is created (pending)', function () {
-  pm.response.to.have.status(200);
-  const json = pm.response.json();
-  pm.expect(json).to.have.property('status_code');
-  pm.expect(json.status_code).to.eql('201');
-  pm.expect(json.transaction_status).to.eql('pending');
-});
-```
-
-Di `4) Payment Status`, periksa status:
-
-```javascript
-pm.test('Status returns transaction info', function () {
-  pm.response.to.have.status(200);
-  const json = pm.response.json();
-  pm.expect(json).to.have.property('order_id');
-  pm.expect(json).to.have.property('transaction_status');
-});
-```
-
-### 4) Menambah Request GoPay/QR (Opsional)
-Jika Anda ingin menguji GoPay/QR, tambahkan request baru di koleksi:
-
-- Method: `POST`
-- URL: `{{baseUrl}}/api/payments/charge`
-- Body (raw JSON):
-
-```json
-{
-  "payment_type": "gopay",
-  "transaction_details": { "order_id": "{{order_id}}", "gross_amount": 150000 },
-  "gopay": { "enable_qr": true }
-}
-```
-
-Catatan: Bila menghasilkan `400 Bad Request`, cek kembali konfigurasi sandbox merchant dan parameter tambahan yang dibutuhkan (misal `qr_black_white`, `callback_url`).
-
-### 5) Membuka Halaman Pay dari Postman
-Setelah `1) Create Transaction`, variabel `paymentLinkUrl` tersimpan. Anda bisa klik tombol `Open in Browser` (ikon tautan) pada Postman untuk membuka `{{paymentLinkUrl}}` langsung di browser.
-
-### 6) Uji Webhook dengan Pre-request Script
-Tambahkan request baru `Webhook (Manual)` dengan URL `{{baseUrl}}/api/payments/webhook`. Isi body dengan fields Midtrans. Untuk menghitung `signature_key` otomatis, gunakan Pre-request Script berikut (CryptoJS tersedia di sandbox Postman):
-
-```javascript
-// Pre-request: Webhook signature
-const orderId = pm.collectionVariables.get('order_id');
-const statusCode = pm.collectionVariables.get('status_code') || '200';
-const grossAmount = pm.collectionVariables.get('gross_amount') || '150000';
-const serverKey = pm.collectionVariables.get('server_key'); // set di environment
-
-if (!serverKey) {
-  console.warn('server_key is not set in environment');
-}
-
-const raw = String(orderId) + String(statusCode) + String(grossAmount) + String(serverKey);
-const sig = CryptoJS.SHA512(raw).toString(CryptoJS.enc.Hex);
-pm.collectionVariables.set('signature_key', sig);
-```
-
-Body contoh (raw JSON):
-
-```json
-{
-  "order_id": "{{order_id}}",
-  "status_code": "{{status_code}}",
-  "gross_amount": "{{gross_amount}}",
-  "signature_key": "{{signature_key}}",
-  "transaction_status": "settlement"
-}
-```
-
-Tambahkan test sederhana untuk memverifikasi respons webhook:
-
-```javascript
-pm.test('Webhook acknowledged', function () {
-  pm.response.to.have.status(200);
-  const json = pm.response.json();
-  pm.expect(json).to.have.property('ok');
-  pm.expect(json.ok).to.eql(true);
-});
-```
-
-### 7) Postman Runner (Otomasi)
-- Gunakan Runner untuk menjalankan berurutan: `1) Create Transaction` → `2) Resolve Token` → `3) Charge` → `4) Status`.
-- Pastikan environment dipilih. Anda dapat menambah delay antar request jika diperlukan.
-
-### 8) Tips & Variabel Tambahan
-- Sesuaikan `paymentLinkBase` ke port frontend aktif (mis. `5175`).
-- Jika `EXTERNAL_API_KEY` aktif, isi `externalApiKey` di environment.
-- Simpan `server_key` (Midtrans Server Key) di environment untuk uji webhook.
-- Tambahkan `gross_amount`, `status_code` variabel supaya mudah dikustom saat uji webhook/status.

-# Midtrans CIFO Product Requirements Document (PRD)
-
-## 1. Goals and Background Context
-
-### Goals
-- Mendukung pembayaran melalui Midtrans Core API di aplikasi.
-- Menyediakan pilihan metode pembayaran: bank transfer/VA, QRIS, kartu, dan lainnya.
-- Menjamin status transaksi akurat melalui webhook/callback.
-- Menyediakan UI yang jelas untuk memilih metode dan melihat status.
-- Menangani error/timeout dengan retry dan fallback terukur.
-- Menyediakan histori transaksi dan audit trail.
-- Memenuhi kepatuhan keamanan (tokenisasi, PCI-aligned, tidak menyimpan data sensitif).
-- Mendukung testing via sandbox dan konfigurasi multi-environment.
-
-### Background Context
-Integrasi Midtrans Core API memungkinkan aplikasi menggunakan UI sendiri dan berkomunikasi programatik dengan sistem pembayaran Midtrans. Sandbox aktif secara default, sehingga pengujian dapat dilakukan segera. Aktivasi untuk Production memerlukan request aktivasi ke Midtrans. Integrasi harus end-to-end: pembuatan transaksi, pemilihan metode, penanganan callback/webhook, verifikasi status, serta penanganan error. Fokus awal pada MVP yang aman, reliabel, dan mudah diuji.

-
-## 3. User Interface Design Goals
-
-### Overall UX Vision
-- Checkout ringkas, jelas, dan membangun kepercayaan.
-- Minim langkah: pilih metode → tampilkan instruksi/detail → konfirmasi status.
-- Komponen reusable untuk setiap metode; konsisten pola error/feedback.
-
-### Key Interaction Paradigms
-- Pemilihan metode dengan deskripsi singkat dan estimasi waktu bayar.
-- VA: tampilkan nomor VA, bank terkait, expiry, tombol salin, instruksi langkah.
-- QRIS: render QR, countdown expiry, status polling + dukungan callback.
-- Kartu: tokenisasi, dukungan 3DS bila relevan, pesan error yang ramah.
-- Status real-time: pending/sukses/gagal dengan retry/fallback terukur.
-- Skeleton/loading states dan empty states yang informatif.
-
-### Core Screens and Views
-- Pemilihan Metode Pembayaran
-- Detail VA & Instruksi Pembayaran
-- Layar QRIS (QR + timer + status)
-- Form Kartu (tokenisasi + 3DS)
-- Layar Status Pembayaran
-- Riwayat Transaksi Pengguna
-
-### Accessibility (WCAG AA)
-- Fokus yang jelas, kontras memadai, pengumuman status (ARIA live).
-- Alt text pada QR, tidak bergantung warna saja untuk makna.
-
-### Branding
-- Ikuti guideline merek bila tersedia; jika belum, gunakan gaya minimalis.
-- Sertakan indikator kepercayaan (secure, PCI-aligned) tanpa klaim berlebihan.
-
-### Target Device and Platforms
-- Web Responsive; optimasi mobile-first; dukungan desktop.
-- Komponen responsif untuk QR, tabel instruksi, dan form.
-
-## 4. Technical Assumptions
-
-### Repository Structure
-- Monorepo untuk koordinasi modul UI, service, dan webhook.
-
-### Service Architecture
-- Monolith modular + endpoint webhook; opsi job/queue untuk proses asinkron (retry, reconciliation) bila diperlukan.
-
-### Testing Requirements
-- Manual QA Only (tanpa unit/integration/E2E otomatis).
-- Verifikasi dilakukan oleh manusia berdasarkan checklist per metode (VA, QRIS, kartu), langkah verifikasi status (settlement/deny/expire), dan alur error/retry.
-
-### CI/CD
-- Tidak diperlukan (Manual Deployment).
-- Prosedur: set secret env (`MIDTRANS_SERVER_KEY`, `MIDTRANS_CLIENT_KEY`, `MIDTRANS_ENV`), deploy manual, smoke test pascadeploy.
-- Disarankan staging untuk uji manual sebelum produksi.
-
-### Additional Technical Assumptions and Requests
-- Environment & Secrets: `MIDTRANS_BASE_URL` (konfigurabel), `PAYMENT_WEBHOOK_PATH` (mis. `/api/payments/webhook`).
-- Signature & Verification: verifikasi notifikasi via signature (gabungan parameter + `server_key`) dan/atau konfirmasi melalui API Midtrans.
-- Idempotensi & Retry: idempotent key (berbasis `order_id`/`attempt_id`); retry manual terukur; fokus pada “final states”.
-- Observability: logging terstruktur (correlation id per transaksi) dan audit log; review manual berkala.
-- Data Model: `Transaction` (order_id, amount, status, method, timestamps) dan `PaymentAttempt` (attempt_id, method, status, raw_payload).
-- Security: tidak menyimpan data kartu (tokenisasi), dukungan 3DS bila relevan; secret management aman per environment.
-- Platform: asumsi backend PHP/Laravel (Laragon); sesuaikan bila stack berbeda.

-## 7. Epic Details — Epic 2: Implementasi Metode Pembayaran (VA, QRIS, Kartu)
-
-Expanded Goal: Menyelesaikan alur pembayaran untuk Virtual Account (VA), QRIS, dan Kartu (tokenisasi + 3DS) end-to-end, termasuk UI, validasi input, idempotensi, penanganan error/expiry, dan pembaruan status transaksi via webhook/polling sesuai Midtrans Core API [0].
-
-Stories & Acceptance Criteria
-
-Story 2.1 — Virtual Account (VA) Payment Flow
-- Functional Acceptance Criteria:
-  1: Server membuat transaksi VA via Core API dan mengembalikan `va_number`, `bank`, `expiry`, dan instruksi pembayaran [0].
-  2: UI menampilkan detail VA (bank, nomor VA, expiry) dengan tombol copy dan instruksi langkah demi langkah.
-  3: Status transaksi diperbarui otomatis melalui webhook (prefer) atau polling; UI mencerminkan status `pending/settlement/expire/deny` secara jelas.
-  4: Idempotensi: percobaan create transaksi untuk order yang sama tidak membuat duplikasi; reattempt menggunakan `attempt_id` baru dengan jejak audit.
-  5: Error handling: downtime bank/invalid VA ditangani dengan pesan jelas dan opsi kembali memilih metode lain.
-  6: Logging & audit: semua event terlog dengan `correlation_id`; record transaksi menyimpan history status.
-
-Story 2.2 — QRIS Payment Flow
-- Functional Acceptance Criteria:
-  1: Server membuat transaksi QRIS; UI merender QR code dari payload (string/image) dan menampilkan expiry countdown [0].
-  2: UI memenuhi aksesibilitas dasar: alt text untuk QR, ARIA live untuk countdown, dan fallback teks instruksi.
-  3: Status diperbarui via webhook (prefer) dengan fallback polling; UI mengubah state ke `pending/settlement/expire/deny`.
-  4: Saat expired, UI menyediakan aksi reattempt (generate QR baru) dengan idempotensi attempt terjaga.
-  5: Error handling: network error/invalid payload ditangani; tidak ada QR usang di-cache; logging terstruktur.
-
-Story 2.3 — Card Payment Flow (Tokenization + 3DS)
-- Functional Acceptance Criteria:
-  1: Tokenisasi kartu dilakukan di klien menggunakan `CLIENT_KEY`; server menerima token dan melakukan charge sesuai Core API [0].
-  2: 3DS challenge/redirect terintegrasi; pengguna menyelesaikan otentikasi dan status final diproses.
-  3: Keamanan: PAN/CVV tidak disimpan; hanya token dan metadata aman; jalur data terenkripsi.
-  4: Idempotensi charge: percobaan ulang tidak menghasilkan double charge; kontrol reattempt terdokumentasi.
-  5: Error & decline mapping: pesan ramah pengguna berdasarkan kode Midtrans; UI menyediakan opsi kembali/memilih metode lain.
-
-Story 2.4 — Common Error & Retry Patterns
-- Functional Acceptance Criteria:
-  1: Standarisasi pesan error lintas metode dengan `code`, `severity`, dan saran tindakan.
-  2: Kontrol retry manual dengan batas percobaan dan panduan backoff; semua percobaan terekam di audit trail.
-  3: Deteksi final-state yang konsisten (settlement/deny/expire) untuk mencegah percobaan tak berujung.
-
-Story 2.5 — Method Abstraction & Extensibility
-- Functional Acceptance Criteria:
-  1: Abstraksi registry metode pembayaran (VA/QRIS/Kartu) sehingga penambahan metode baru (GoPay/ShopeePay) minim perubahan UI.
-  2: Dokumentasi instruksi per-metode untuk QA manual beserta acceptance test skenario.
-  3: Observability tags menyertakan `method`, `attempt_id`, dan `order_id` untuk pelacakan lintas metode.
-
-Opsi Elicitasi (1–9)
-1. Lanjut ke Epic 3 details (Status & Rekonsiliasi)
-2. Analisis alur logis dan dependensi antar-story Epic 2
-3. Evaluasi keselarasan dengan tujuan Epic 2
-4. Identifikasi risiko dan isu tak terduga Epic 2
-5. Tantang dari perspektif kritis (devil’s advocate)
-6. Perspektif tim Agile (PO/SM/Dev/QA)
-7. Stakeholder round table (gabungan sudut pandang)
-8. Validasi self-consistency (bandingkan alternatif sequencing)
-9. Tree of Thoughts deep dive (eksplorasi variasi pemecahan story)
-
-## 8. Epic Details — Epic 3: Status Transaksi & Rekonsiliasi
-
-Expanded Goal: Menjamin status transaksi akurat, konsisten, dan tersinkron antara UI, data store internal, serta Midtrans. Menyediakan penanganan webhook yang reliabel, fallback polling, state machine yang jelas, proses rekonsiliasi berkala, dan runbook operasional yang mendukung QA manual.
-
-Stories & Acceptance Criteria
-
-Story 3.1 — State Machine Status Transaksi
-- Functional Acceptance Criteria:
-  1: Definisikan state internal beserta mapping ke Midtrans: `initiated`, `pending`, `challenge` (3DS), `settlement`, `deny`, `cancel`, `expire`, `refund` (opsional). Final states ditandai dan tidak menerima transisi lebih lanjut kecuali override manual ber-audit.
-  2: Aturan transisi valid terdokumentasi; mencegah regresi status (mis. dari `settlement` kembali ke `pending`) kecuali kasus khusus yang disetujui dan berjejak audit.
-  3: Persist status perubahan dengan metadata `source` (webhook/polling/manual), `updated_by` (system/user), dan `occurred_at`.
-  4: Idempotensi update: notifikasi duplikat tidak membuat perubahan status ganda; gunakan kunci unik berbasis `transaction_id + status + provider_event_time`.
-  5: Concurrency control: update status menggunakan locking/versi agar paralel event tidak menyebabkan lost update.
-
-Story 3.2 — Webhook Processing Reliabel
-- Functional Acceptance Criteria:
-  1: Verifikasi signature notifikasi Midtrans; request invalid ditolak dengan log jelas dan tidak memutakhirkan status [0].
-  2: Toleransi out-of-order: notifikasi yang datang tidak berurutan tetap menghasilkan status konsisten sesuai prioritas transisi yang diizinkan.
-  3: Respons endpoint cepat (200 OK) setelah validasi dasar; pemrosesan lebih berat mencatat event dan memutakhirkan status secara sinkron sederhana (tanpa bergantung CI/CD) dengan error handling.
-  4: Retry pada error transient tercatat dengan batas percobaan; idempotensi terjaga sehingga tidak ada double update.
-  5: Logging & audit: setiap event webhook memiliki `event_id`, `correlation_id`, payload ringkas, hasil verifikasi, dan dampak terhadap status.
-
-Story 3.3 — Fallback Polling Status
-- Functional Acceptance Criteria:
-  1: Bila dalam SLA tidak ada webhook, sistem dapat melakukan polling status ke Midtrans untuk transaksi yang `pending` dan menyimpan hasilnya [0].
-  2: Polling memiliki backoff dan batas percobaan; status hasil polling ditandai `source=polling` dan diverifikasi terhadap aturan transisi.
-  3: UI dan data store merepresentasikan status final secara konsisten; mismatch dicatat sebagai `requires_investigation`.
-
-Story 3.4 — Rekonsiliasi Berkala (Manual/Schedule)
-- Functional Acceptance Criteria:
-  1: Tersedia perintah/skrip rekonsiliasi yang dapat dijalankan manual (mis. artisan/CLI) untuk mengecek status Midtrans terhadap transaksi lokal dalam periode tertentu.
-  2: Laporan rekonsiliasi dihasilkan (CSV/JSON) berisi `order_id`, `transaction_id`, `method`, `amount`, `status_local`, `status_midtrans`, dan rekomendasi resolusi.
-  3: Transaksi dengan mismatch ditandai `requires_investigation`; runbook menyertakan langkah koreksi (re-fetch status, reprocess event) dan dokumentasi hasil.
-
-Story 3.5 — Audit Trail & Export
-- Functional Acceptance Criteria:
-  1: Timeline perubahan status per transaksi tersedia (internal), termasuk sumber perubahan dan waktu kejadian.
-  2: Ekspor CSV untuk Finance/Operasional mencakup filter periode, metode, dan status final.
-  3: Observability tags konsisten: `order_id`, `transaction_id`, `method`, `status`, `attempt_id`, `correlation_id`.
-
-Story 3.6 — Runbook Operasional
-- Functional Acceptance Criteria:
-  1: Dokumentasi langkah-langkah: validasi signature, re-run webhook (simulasi), polling manual, interpretasi kode status, dan tindakan korektif.
-  2: Panduan troubleshooting untuk kasus umum: notifikasi tidak datang, duplikasi notifikasi, mismatch status, timeout.
-  3: Exit criteria rekonsiliasi: seluruh transaksi dalam periode uji memiliki status final konsisten, tidak ada mismatch terbuka.
-
-Opsi Elicitasi (1–9)
-1. Lanjut ke Epic 4 details (Refund/Void & Operasional)
-2. Analisis dependensi antar-story Epic 3
-3. Evaluasi keselarasan dengan tujuan Epic 3
-4. Identifikasi risiko dan isu tak terduga Epic 3
-5. Tantang dari perspektif kritis (devil’s advocate)
-6. Perspektif tim Agile (PO/SM/Dev/QA)
-7. Stakeholder round table (gabungan sudut pandang)
-8. Validasi self-consistency (bandingkan alternatif sequencing)

-# Sprint Change Proposal — ERP → Create Transaction → Payment Link Flow
-
-## Summary
-- Trigger: Checkout tidak lagi dimulai dari tombol “Buy Now” di frontend. Sistem eksternal (ERP/billing script) mengirim data transaksi ke server dan menerima tautan pembayaran terenkripsi untuk dibagikan ke pengguna.
-- Outcome: Backend menjadi titik inisiasi transaksi. Pengguna membuka Payment Page via link (`/pay/:token`), memilih metode (VA/GoPay/Cstore/Kartu), lalu UI mengeksekusi charge seperti biasa. Webhook Midtrans dan ERP callback tetap berjalan.
-
-## Objectives (Sprint)
-- Menyediakan endpoint backend `POST /createtransaksi` yang mengeluarkan payment link bertanda-tangan (HMAC‑SHA256) dengan TTL dan anti‑replay.
-- Menambahkan rute frontend `"/pay/:token"` (Payment Page) untuk memvalidasi token, menampilkan metode, dan melakukan charge menggunakan `order_id` dari token.
-- Menjaga kompatibilitas endpoint yang ada: `POST /api/payments/charge`, `GET /api/payments/:orderId/status`, `POST /api/payments/webhook`.
-- Menyelaraskan PRD, Arsitektur UI, dan Story E2E dengan alur baru.
-
-## Scope & Impact
-- PRD (`docs/prd.md`): Tambah FR “External Create Transaction & Payment Link”, ubah sumber `order_id` (berasal dari `item_id`), tambahkan ketentuan TTL, signature, dan anti‑replay.
-- Arsitektur UI (`docs/ui-architecture.md`): Tambah rute `"/pay/:token"`, alur token‑driven. `CheckoutPage` tetap sebagai demo/QA.
-- Story E2E (`docs/stories/midtrans-e2e-checkout-to-webhook.md`): Mulai dari Payment Page via token, bukan dari CheckoutPage langsung.
-- Backend (`server/index.cjs`): Tambah endpoint `POST /createtransaksi` dan resolver token (API untuk FE). Env baru: `EXTERNAL_API_KEY`, `PAYMENT_LINK_SECRET`, `PAYMENT_LINK_TTL_MINUTES`.
-- Frontend: Tambah halaman `PayPage` (`/pay/:token`), service untuk resolve token. `postCharge/getPaymentStatus` tetap.
-
-## Proposed Design
-
-### 1) Backend — Create Transaction API
-- Endpoint: `POST /createtransaksi`
-- Auth: Header `X-API-KEY: <EXTERNAL_API_KEY>` (validasi exact match; opsi IP whitelist & rate limit di reverse proxy).
-- Body (contoh minimal):
-  ```json
-  {
-    "merchant_id": "TKG-250520029803",
-    "deskripsi": "Pembelian item",
-    "nominal": 200000,
-    "nama": "Dwiki Kurnia Sandi",
-    "no_telepon": "081234567890",
-    "email": "demo@example.com",
-    "item": [
-      { "item_id": "ITEM-12345", "qty": 1, "price": 200000, "name": "Produk A" }
-    ]
-  }
-  ```
-  - Mapping `order_id`: gunakan `"mercant_id:item_id"` bila keduanya tersedia (contoh: `MERC-001:ITEM-12345`). Jika salah satu tidak ada, fallback ke `item[0].item_id` atau `mercant_id`. Tujuan: item yang sama pada merchant berbeda tetap menghasilkan order unik sehingga link bisa diterbitkan.
-- Idempotensi: jika `order_id` + `nominal` sama dan status transaksi masih `pending`, kembalikan payment link sebelumnya; jika `nominal` berbeda, kembalikan `422 AMOUNT_MISMATCH`.
-- Response (sukses):
-  ```json
-  {
-    "status_code": "200",
-    "status_message": "OK",
-    "url": "https://cifopayment.id/pay/<token>?sig=<signature>",
-    "exp": 1730000000
-  }
-  ```
-  - `token`: opaque base64url berisi klaim minimal (mis. `order_id`, `nominal`, `exp`) yang disimpan server.
-  - `signature`: `hex(HMAC_SHA256(token, PAYMENT_LINK_SECRET))`.
-  - `exp`: UNIX epoch seconds (TTL default 30 menit; dapat dikonfigurasi).
-
-### 2) Backend — Payment Link Resolve API
-- Endpoint: `GET /api/payment-links/:token` (digunakan frontend untuk bootstrap Payment Page).
-- Query: otomatis memverifikasi signature (`sig` di query atau header), TTL/anti‑replay, dan mengembalikan payload:
-  ```json
-  {
-    "order_id": "ITEM-12345",
-    "nominal": 200000,
-    "customer": { "name": "Dwiki", "phone": "081234567890", "email": "demo@example.com" },
-    "expire_at": 1730000000,
-    "allowed_methods": ["bank_transfer", "gopay", "cstore", "credit_card"]
-  }
-  ```
-- Error: `401 INVALID_SIGNATURE`, `410 LINK_EXPIRED`, `409 LINK_USED` (opsional jika anti‑replay menandai sekali pakai).
-
-### 3) Frontend — Payment Page (`/pay/:token`)
-- Flow:
-  - Ambil `token` dari URL → panggil `GET /api/payment-links/:token`.
-  - Set lokal `orderId`, `amount`, `expireAt`, dan info pelanggan.
-  - Render komponen metode (VA/GoPay/Cstore/Kartu) seperti di Checkout, tetapi `orderId` berasal dari token.
-  - Setelah charge, navigasi ke `"/payments/:orderId/status"` (polling status tetap).
-- Catatan: `CheckoutPage` tetap ada untuk demo/QA; jalur produksi menggunakan Payment Page via link.
-
-### 4) Webhook & ERP Callback
-- Tetap: `POST /api/payments/webhook` memverifikasi signature Midtrans dan memperbarui status.
-- ERP Callback: kirim `POST` ke `https://apibackend.erpskrip.id/paymentnotification/` pada status sukses, signature `sha512(mercant_id + status_code + nominal + client_id)` seperti implementasi saat ini.
-
-### 5) Security & Config
-- Secrets:
-  - `EXTERNAL_API_KEY`: memvalidasi `X-API-KEY` dari ERP.
-  - `PAYMENT_LINK_SECRET`: kunci HMAC untuk signature token.
-  - `PAYMENT_LINK_TTL_MINUTES`: default 30.
-- Praktik:
-  - Rate‑limit `POST /createtransaksi` dan audit log.
-  - Anti‑replay: tandai token sebagai “used” setelah berhasil charge (opsional; atau izinkan reuse sampai status final).
-  - Rotasi secret terjadwal; invalidasi token lama secara bertahap bila diperlukan.
-
-## Acceptance Criteria (Sprint)
-- Backend mengeluarkan payment link dengan `token` + `signature`, valid hingga TTL.
-- Resolve API mengembalikan `order_id` dan `nominal` yang konsisten; invalid jika signature/TTL gagal.
-- Frontend Payment Page (`/pay/:token`) dapat:
-  - Memvalidasi token dan menampilkan metode pembayaran.
-  - Melakukan charge via endpoint yang ada menggunakan `order_id` dari token.
-  - Menavigasi ke halaman status dan menampilkan detail (VA/QR/payment code/kartu) sesuai metode.
-- Webhook menerima notifikasi Midtrans dan ERP callback tetap terkirim saat sukses.
-- Dokumentasi PRD, Arsitektur UI, dan Story E2E diperbarui mencerminkan alur baru.
-
-## Non‑Functional Requirements
-- Observability: logging request ID, event penting (`link.create`, `link.resolve`, `charge.start/success`, `webhook.receive`).
-- Idempotensi: kembalikan link lama untuk transaksi `pending` dengan `order_id` + `nominal` yang sama.
-- Keamanan: tidak mengekspos server key; signature Midtrans diverifikasi; token link ditandatangani HMAC‑SHA256.
-- Kinerja: endpoint create/resolver respon <200ms p95 (lokal dev).
-
-## Risks & Mitigations
-- Replay/penyalahgunaan link: enforce TTL, anti‑replay flag, rate‑limit.
-- Konflik `order_id`: validasi unik; strategy untuk recurring (suffix waktu/sequence bila diperlukan).
-- Ketidaksesuaian nominal: `422 AMOUNT_MISMATCH` untuk `order_id` sama namun nominal beda.
-- Gangguan ERP: retry callback dengan backoff, feature flag `ERP_ENABLE_NOTIF` untuk mematikan sementara.
-
-## Rollback Plan
-- Nonaktifkan konsumsi resolver token (feature flag) dan kembalikan ke alur Checkout demo.
-- Pertahankan endpoint status & webhook agar UI tetap dapat polling status.
-
-## Deliverables (Sprint)
-- Backend: `POST /createtransaksi`, `GET /api/payment-links/:token` (validator signature/TTL), konfigurasi env baru.
-- Frontend: halaman `PayPage` (`/pay/:token`) dengan integrasi panel metode yang ada.
-- Docs: update PRD, Arsitektur UI, dan Story E2E sesuai token‑driven flow.
-
-## Timeline & Tasking (5 hari)
-- Day 1: Skeleton endpoint `createtransaksi` + HMAC signing + env wiring.
-- Day 2: Resolver API + idempotensi + anti‑replay dasar.
-- Day 3: FE `PayPage` + service `getPaymentLinkPayload(token)` + navigasi.
-- Day 4: QA manual (sandbox) + webhook/ERP callback sanity.
-- Day 5: Dokumentasi & polish (error codes, logging, runbook).
-
-## Decisions Confirmed
-- TTL payment link: 30 menit (konfigurabel; default 30) — disetujui.
-- Token: HMAC‑SHA256 signature (tanpa enkripsi payload; confidentiality tidak diwajibkan saat ini).
-- Recurring transaksi: tidak didukung. Kebijakan:
-  - Satu transaksi aktif per `item_id` pada satu waktu.
-  - Jika status sukses (`settlement` atau `capture + fraud_status=accept`), permintaan baru untuk `item_id` yang sama ditolak (`409 ORDER_COMPLETED`).
-  - Re-attempt diperbolehkan hanya jika transaksi sebelumnya tidak sukses dan sudah berakhir (`expire/cancel/deny`), menggunakan kebijakan unik `order_id` sesuai kebutuhan implementasi Midtrans.
-
-## Appendix — Example
-- Request `POST /createtransaksi` (ringkas): lihat contoh pada bagian Backend di atas.
-- Response sukses:
-  ```json
-  {
-    "status_code": "200",
-    "status_message": "OK",
-    "url": "https://cifopayment.id/pay/eyJvcmRlcl9pZCI6IklURU0tMTIzNDUiLCJub21pbmFsIjoyMDAwMDAsImV4cCI6MTczMDAwMDAwMH0?sig=4c7f...",
-    "exp": 1730000000
-  }
-  ```

-# Checkout Wizard untuk Demo Store (1 Produk) - Brownfield Addition
-
-## Status Story
-- Status: Approved
-- Disetujui oleh: John (PM)
-- Tanggal: 2025-11-08
-
-## User Story
-
-Sebagai pengguna demo toko,
-Saya ingin membeli satu produk melalui alur checkout bertahap (step-by-step) dan memilih metode pembayaran di langkah terpisah,
-Agar demo alur belanja jelas, ringkas, dan mudah dipahami.
-
-## Story Context
-
-**Existing System Integration:**
-- Integrates with: `src/pages/CheckoutPage.tsx`, komponen pembayaran di `src/features/payments/components/*`
-- Technology: React + Vite + Tailwind
-- Follows pattern: Reuse komponen `PaymentMethodList` dan panel metode (Bank/Card/GoPay), state-driven UI tanpa perubahan arsitektur
-- Touch points: `PaymentMethodList.tsx`, `BankTransferPanel.tsx`, `CardPanel.tsx`, `GoPayPanel.tsx`
-
-## Acceptance Criteria
-
-**Functional Requirements:**
-1. Tersedia halaman Demo Store berisi 1 produk dengan tombol `Buy Now`.
-2. Klik `Buy Now` mengarahkan ke `Checkout Page` dengan form checkout yang menampilkan field: Nama, Email/HP, Alamat, dan Catatan; seluruh field terisi nilai dummy default (editable) untuk keperluan demo.
-3. Setelah konfirmasi form, pengguna masuk ke langkah pemilihan metode pembayaran (Step 2).
-4. Pemilihan metode pembayaran dilakukan di langkah terpisah, bukan dropdown/accordion pada halaman yang sama seperti saat ini.
-5. Setelah memilih metode (Bank Transfer / Kartu / GoPay/QRIS), pengguna masuk ke langkah berikutnya (Step 3) yang menampilkan panel/instruksi sesuai metode terpilih.
-6. Tersedia tombol `Back` untuk kembali ke langkah sebelumnya (mis. dari Step 3 ke Step 2 untuk mengganti metode).
-7. Flow bekerja mulus di dev server tanpa error browser/terminal.
-
-**Integration Requirements:**
-8. Fungsi panel pembayaran yang ada tetap digunakan (reusable) tanpa perubahan API backend.
-9. Tidak ada regresi pada halaman status pembayaran (`PaymentStatusPage.tsx`) dan riwayat pembayaran (`PaymentHistoryPage.tsx`).
-10. Tetap mengikuti pola styling dan komponen yang ada (Tailwind, komponen internal) agar konsisten.
-
-**Quality Requirements:**
-11. Navigasi antar langkah jelas (indikator step atau label sederhana) dan dapat dioperasikan dengan keyboard.
-12. Dokumentasi singkat alur (README atau komentar terstruktur) ditambahkan bila perlu.
-13. Verifikasi manual dilakukan: pilih setiap metode dan pastikan panel/instruksi tampil sesuai.
-14. Layout, card, dan grid yang ada TIDAK diubah (wrapper, spacing, breakpoints tetap).
-15. Tidak mengubah ukuran container, struktur grid, atau komponen kartu; hanya pengaturan visibilitas/kondisional antar langkah.
-
-## Technical Notes
-
-- Integration Approach: Implementasi wizard berbasis state di `CheckoutPage.tsx` (Step 1: konfirmasi data, Step 2: pilih metode, Step 3: panel metode). Hindari perubahan routing besar; tetap di `/checkout` untuk kesederhanaan.
-- Existing Pattern Reference: Gunakan komponen `PaymentMethodList` untuk Step 2 (list-only), dan render panel metode di Step 3 berdasarkan pilihan.
-- Key Constraints: Minimalkan perubahan pada arsitektur; jangan mengubah kontrak API atau data model pembayaran. Jaga konsistensi UI. Jangan sentuh wrapper layout (grid, card, container), hindari perubahan spacing/breakpoints — hanya atur visibilitas komponen antar langkah.
- - Dummy Form Fields: Nama, Email/HP, Alamat, Catatan dengan nilai default: "Demo User", "demo@example.com" / "081234567890", "Jl. Contoh No. 1", dan Catatan kosong/opsional. Semua nilai editable; tidak diperlukan validasi berat untuk demo.
-
-## Definition of Done
-
-- [ ] Functional requirements terpenuhi (demo 1 produk → checkout dummy → pilih metode → panel langkah berikutnya)
-- [ ] Integration requirements terverifikasi (komponen lama dipakai kembali; status/history tidak regresi)
-- [ ] Regression manual terhadap alur pembayaran yang sudah ada
-- [ ] Kode mengikuti pola dan standar proyek (React, Tailwind)
-- [ ] Dev server berjalan tanpa error; flow diuji untuk semua metode
-- [ ] Dokumentasi ringkas alur ditambah bila perlu
-
-## Risk and Compatibility Check
-
-**Minimal Risk Assessment:**
-- Primary Risk: Perubahan alur UI dapat mempengaruhi asumsi pengguna lama yang terbiasa dengan accordion.
-- Mitigation: Sediakan tombol `Back` dan label step yang jelas; lakukan pengujian manual untuk semua metode.
-- Rollback: Kembalikan rendering panel ke model accordion (seperti implementasi saat ini) jika diperlukan.
-
-**Compatibility Verification:**
-- [ ] Tidak ada perubahan pada API publik/back-end
-- [ ] Tidak ada perubahan DB
-- [ ] Perubahan UI mengikuti pola Tailwind/komponen internal
-- [ ] Dampak performa diabaikan (UI lokal/state)
-
-## Validation Checklist
-
-**Scope Validation:**
-- [ ] Dapat diselesaikan dalam satu sesi pengembangan
-- [ ] Integrasi straightforward (komponen yang ada digunakan ulang)
-- [ ] Mengikuti pola yang sudah ada
-- [ ] Tidak perlu desain/arsitektur baru
-
-**Clarity Check:**
-- [ ] Requirement jelas dan tidak ambigu
-- [ ] Titik integrasi ditentukan (CheckoutPage, PaymentMethodList, panel metode)
-- [ ] Kriteria sukses dapat diuji (navigasi step, panel tampil sesuai)
-- [ ] Rollback sederhana (kembali ke accordion)
-
----
-
-### Out-of-Scope
-- Multi-route wizard (mis. `/checkout/step/2`) — tetap single-route untuk kesederhanaan.
-- Perubahan kontrak API pembayaran atau penambahan metode baru.
-- Penataan ulang besar desain visual di luar kebutuhan stepper sederhana.
-
-### Implementasi Minimal yang Direkomendasikan
-- Tambah state `currentStep` di `CheckoutPage.tsx` dengan nilai: 1 (Form Dummy) → 2 (Pilih Metode) → 3 (Panel Metode).
-- Refactor rendering: `PaymentMethodList` hanya list dan memilih metode di Step 2; panel detail dirender di Step 3 berdasarkan pilihan.
-- Tambah kontrol `Next`/`Back` untuk perpindahan step.
-- Jangan ubah wrapper layout (grid, card, container) yang sudah rapi; tetap gunakan struktur/kelas yang ada dan hanya ubah visibilitas komponen sesuai step.
- - Prefill form Step 1 dengan nilai dummy default dan lanjutkan ke Step 2 lewat tombol `Next` tanpa memaksa validasi berat.

-# Story: End-to-End Midtrans — Checkout → Webhook (Payment Sukses)
-
-## User Story
-Sebagai pembeli,
-Saya ingin menyelesaikan pembayaran melalui Midtrans dan melihat status pembayaran otomatis diperbarui melalui webhook,
-Sehingga saya mendapatkan konfirmasi yang jelas dan pesanan saya segera diproses.
-
-## Story Context
-**Integrates with:**
-- Frontend: `src/pages/CheckoutPage.tsx`, `src/features/payments/components/*` (BankTransferPanel, CardPanel, GoPayPanel, CStorePanel), `src/pages/PaymentStatusPage.tsx`, hooks `usePaymentStatus`, navigasi `usePaymentNavigation`
-- Backend: `server/index.cjs` — endpoint `POST /api/payments/charge`, `GET /api/payments/:orderId/status`, penambahan `POST /api/payments/webhook`
-- Services: `src/services/api.ts` (`postCharge`, `getPaymentStatus`)
-
-**Technology:** React + Vite, TanStack Query (polling status), Express, `midtrans-client` Core API, Midtrans 3DS (kartu).
-
-**Follows pattern:** Semua panggilan ke Midtrans dilakukan via backend; UI menavigasi ke halaman status (`/payments/:orderId/status`) dan melakukan polling hingga status final; webhook memperbarui status di backend sebagai sumber kebenaran utama.
-
-## Flow Overview
-1) Checkout
-- Pengguna memilih metode: `bank_transfer` (VA/echannel), `gopay` (QRIS/GoPay), `cstore` (Alfamart/Indomaret), `credit_card` (tokenisasi + 3DS).
-- UI menampilkan panel sesuai metode dan mengumpulkan input yang diperlukan.
-
-2) Charge (Backend)
-- Frontend memanggil `POST /api/payments/charge` via `postCharge(payload)`.
-- Backend meneruskan ke Midtrans `core.charge(payload)` dan mengembalikan respons (termasuk `order_id`, `transaction_status`, serta `redirect_url` untuk kartu jika 3DS diperlukan).
-
-3) 3DS (Kartu)
-- Bila respons berisi `redirect_url`, UI memanggil `authenticate3ds(redirect_url)` untuk challenge 3DS.
-- Setelah 3DS selesai, status akan menjadi `capture` (berhasil) atau status lain sesuai penilaian fraud.
-
-4) Status Page + Polling
-- UI menavigasi ke `/payments/:orderId/status` (opsional: `?m=<method>`).
-- Halaman melakukan polling `GET /api/payments/:orderId/status` setiap 3 detik sampai status final: `settlement`, `capture`, `expire`, `cancel`, `deny`, `refund`, `chargeback`.
-
-5) Webhook (Notifikasi Midtrans)
-- Backend menyediakan `POST /api/payments/webhook` untuk menerima notifikasi transaksi.
-- Backend memverifikasi `signature_key` dan memperbarui status transaksi (DB/in-memory) sebagai sumber kebenaran.
-- UI tetap polling hingga menangkap status final (atau dapat diinformasikan melalui SSE jika ditambahkan kemudian).
-
-6) Success Outcome
-- Untuk `bank_transfer/gopay/cstore`: status `settlement` dianggap sukses.
-- Untuk `credit_card`: status `capture` dengan `fraud_status=accept` dianggap sukses.
-- UI menampilkan badge hijau “Pembayaran berhasil” dan detail metode (VA, QR links, masked card, dsb.).
-
-7) ERP Notification (External Callback)
-- Ketika pembayaran sukses, backend mengirim callback ke ERP pada URL `https://apibackend.erpskrip.id/paymentnotification/`.
-- Metode: `POST`, Body JSON berisi:
-  - `data`: `{ channel, nominal, mercant_id, customer_name }`
-  - `status_code`: selalu `"200"` untuk pembayaran sukses
-  - `signature`: `sha512(mercant_id + status_code + nominal + client_id)` dalam hex lowercase
-- `client_id` disediakan oleh konfigurasi backend (contoh env `ERP_CLIENT_ID`).
-
-## Acceptance Criteria
-- Checkout
-  - Pengguna dapat memilih metode Midtrans dan melihat panel input/instruksi yang sesuai.
-  - Tombol “Bayar” mengirim charge ke backend dan menampilkan feedback loading/error yang ramah.
-- Charge & 3DS
-  - `credit_card`: tokenisasi via 3DS SDK; jika wajib 3DS, UI mengarahkan ke challenge lalu kembali ke halaman status.
-  - `bank_transfer/gopay/cstore`: charge mengembalikan detail VA/QR/payment code sesuai; UI menampilkan instruksi yang relevan.
-- Status Page
-  - Halaman status menampilkan `order_id`, metode, dan badge status: `pending` (kuning), `settlement/capture` (hijau), `deny/cancel/expire/refund/chargeback` (merah).
-  - Polling berhenti otomatis ketika status final.
-- Webhook Backend
-  - Endpoint `POST /api/payments/webhook` tersedia dan tervalidasi signature Midtrans.
-  - Status transaksi diperbarui idempoten (repeat notification tidak merusak data), menyimpan metadata minimal: `source=webhook`, `occurred_at`.
-  - Logging mencatat event webhook, hasil verifikasi, dan perubahan status.
-- Success Case
-  - Setelah pembayaran sukses (settlement/capture), UI menampilkan konfirmasi “Pembayaran berhasil” dan menyediakan navigasi “Lihat Riwayat” dan “Kembali ke Checkout”.
-- ERP Notification
-  - Saat status sukses (VA/GoPay/QRIS/Cstore = `settlement`, Kartu = `capture` + `fraud_status=accept`), backend melakukan `POST` ke `https://apibackend.erpskrip.id/paymentnotification/` dengan body:
-    - `data`: `{ channel: <string>, nominal: <number>, mercant_id: <string>, customer_name: <string> }`
-    - `status_code`: `"200"`
-    - `signature`: hasil `sha512(mercant_id + status_code + nominal + client_id)`
-  - Signature tervalidasi di sisi ERP (nilai harus cocok dengan rumus).
-  - Callback idempoten (jika dipanggil ulang karena retry, tidak menggandakan efek di ERP).
-- Keamanan & Ketahanan
-  - Server Key tidak terekspos ke frontend.
-  - Verifikasi signature sesuai rumus Midtrans; input sensitif (token_id, card data) tidak tercatat di log.
-  - Fallback polling tetap bekerja jika webhook terlambat.
-
-## Technical Notes
-- Endpoint backend saat ini:
-  - `POST /api/payments/charge` — sudah ada (pass-through ke Midtrans Core API)
-  - `GET /api/payments/:orderId/status` — sudah ada (memanggil `core.transaction.status(orderId)`).
-  - Tambahkan: `POST /api/payments/webhook` — menerima notifikasi Midtrans.
-
-- Verifikasi Signature Midtrans (HTTP Notification)
-  - `signature_key = sha512(order_id + status_code + gross_amount + serverKey)` (hex lowercase)
-  - Contoh Node.js:
-    ```js
-    const crypto = require('crypto')
-    const signature = crypto
-      .createHash('sha512')
-      .update(orderId + statusCode + grossAmount + serverKey)
-      .digest('hex')
-    const isValid = signature === req.body.signature_key
-    ```
-
-- Status Mapping (UI)
-  - Final: `settlement`, `capture`, `expire`, `cancel`, `deny`, `refund`, `chargeback`.
-  - Sukses: `settlement` (VA/QR/Cstore), `capture` + `fraud_status=accept` (Card).
-  - Normalisasi di `src/features/payments/lib/midtrans.ts` melalui `normalizeMidtransStatus`.
-
-- ERP External Notification (Backend → ERP)
-  - Kirim callback hanya ketika status sukses:
-    - VA/GoPay/QRIS/Cstore: `transaction_status === 'settlement'`
-    - Kartu: `transaction_status === 'capture'` dan `fraud_status === 'accept'`
-  - Payload contoh:
-    ```json
-    {
-      "data": {
-        "channel": "DANA",
-        "nominal": 200000,
-        "mercant_id": "TKG-250520029803",
-        "customer_name": "Dwiki Kurnia Sandi"
-      },
-      "status_code": "200",
-      "signature": "<hex sha512>"
-    }
-    ```
-  - Perhitungan signature (Node.js):
-    ```js
-    const crypto = require('crypto')
-    const mercantId = data.mercant_id
-    const nominal = String(data.nominal)
-    const statusCode = '200'
-    const clientId = process.env.ERP_CLIENT_ID || ''
-    const raw = `${mercantId}${statusCode}${nominal}${clientId}`
-    const signature = crypto.createHash('sha512').update(raw).digest('hex')
-    ```
-  - Pengiriman (contoh menggunakan fetch):
-    ```js
-    const res = await fetch('https://apibackend.erpskrip.id/paymentnotification/', {
-      method: 'POST',
-      headers: { 'Content-Type': 'application/json' },
-      body: JSON.stringify({ data, status_code: '200', signature })
-    })
-    if (!res.ok) throw new Error(`ERP notify failed: ${res.status}`)
-    ```
-  - Idempotensi: gunakan kunci unik (mis. `order_id`) untuk memastikan sekali proses pada ERP; lakukan retry dengan backoff jika gagal.
-
-## Test Cases (Sandbox)
-- Credit Card (3DS)
-  - Input kartu sandbox → tokenisasi → challenge 3DS → kembali ke status → `capture` + `fraud_status=accept` → UI sukses.
-- Bank Transfer (VA Permata/Mandiri E-Channel)
-  - Charge menghasilkan VA → UI menampilkan VA dan bank → simulasi pembayaran → webhook atau polling → `settlement` → UI sukses.
-- GoPay/QRIS
-  - Charge menghasilkan `actions` (deeplink/QR) → buka tautan → `settlement` → UI sukses.
-  - Backend mengirim ERP callback dengan `status_code="200"` dan signature valid.
-- Negative/Edge
-  - Tidak bayar dalam waktu batas → `expire` → UI merah, polling berhenti.
-  - `deny/cancel` → UI merah; riwayat mencatat status akhir.
-  - ERP callback tidak dikirim untuk status non-sukses.
-
-## Dependencies & Config
-- Env Frontend: `VITE_API_BASE_URL`, `VITE_MIDTRANS_CLIENT_KEY`, `VITE_MIDTRANS_ENV` (sandbox/production).
-- Env Backend: `MIDTRANS_SERVER_KEY`, `MIDTRANS_CLIENT_KEY` (opsional untuk log), `MIDTRANS_IS_PRODUCTION`.
-- Toggle fitur: `GET/POST /api/config` (bank_transfer, credit_card, gopay, cstore). Pastikan metode yang digunakan aktif.
-- ERP Notifikasi:
-  - `ERP_NOTIFICATION_URL="https://apibackend.erpskrip.id/paymentnotification/"`
-  - `ERP_CLIENT_ID="<dari ERP>"`
-  - Opsional: `ERP_ENABLE_NOTIF=true` (feature flag untuk mengaktifkan/nonaktifkan callback)
-
-## Validation Checklist
-- [ ] Perubahan dapat selesai dalam satu sesi (dokumen + endpoint webhook kecil)
-- [ ] Integrasi mengikuti pola yang ada (`postCharge`, `getPaymentStatus`, polling)
-- [ ] Tidak ada kebutuhan arsitektur baru besar
-- [ ] Acceptance criteria dapat diuji di sandbox
-- [ ] Rollback sederhana: nonaktifkan webhook, andalkan polling sementara
-- [ ] ERP callback dikirim pada status sukses dengan `status_code="200"` dan signature sesuai
-
-## Rollback & Risk
-- Rollback: nonaktifkan konsumsi webhook (feature flag), gunakan polling status sementara.
-- Risiko: signature salah, keterlambatan webhook, idempotensi tidak benar. Mitigasi: verifikasi ketat, logging, dan retry aman.
-- Risiko ERP: endpoint tidak tersedia atau timeouts. Mitigasi: retry dengan backoff, dead-letter queue (opsional), observabilitas.
-
-## Out of Scope
-- Metode eksternal non‑Midtrans (contoh: cPay/CIFO Token) tidak termasuk dalam skenario sukses Midtrans ini.
-- Refund/chargeback flow admin; hanya ditampilkan sebagai status jika terjadi.
-
-## Notes
-- Rujuk `docs/integration-midtrans.md` untuk detail kartu/3DS.
-- Tambahkan dokumentasi runbook QA untuk simulasi webhook dan verifikasi status manual.
