feat: add printer types

CreateOrderContractToModel never copied customer_id, so every order from
POST /orders was saved without a customer. Paying it then earned no
EnakPoint or EnakCoin (skipped as NO_CUSTOMER, which is not logged).

The customer must now belong to the order's organization, as
SetOrderCustomer already requires: it is who earns once the order is paid,
and orders.customer_id has no foreign key. A nil UUID means no customer.

+# API EnakPoint & EnakCoin
+
+30 Sep 2026
+
+Semua endpoint EnakPoint (`POINT`, bisa bayar order) dan EnakCoin (`COIN`, untuk game dan ditukar ke EnakPoint) ada di bawah base URL `/api/v1`, memakai satu format response, dan semua jumlah berupa bilangan bulat.
+
+## Konvensi umum
+
+| Klien | Autentikasi | Prefix |
+| --- | --- | --- |
+| Customer app / self-order | `Authorization: Bearer <token customer>` | `/api/v1/customer` |
+| POS | Token user (kasir/manager) | `/api/v1` |
+| Dashboard | Token user, role Admin atau Manager | `/api/v1/marketing`, `/api/v1/outlets` |
+
+**Format response.** Sukses: `{"success": true, "data": {…}, "errors": null}`. Gagal: `{"success": false, "data": null, "errors": [{"code": "304", "entity": "wallet_service", "cause": "…"}]}`. Tampilkan `cause` sebagai alasan penolakan.
+
+| `code` | HTTP | Arti |
+| --- | --- | --- |
+| `303`, `310` | 400 | Body atau parameter tidak lengkap / salah format |
+| `304` | 400 | Ditolak aturan bisnis (saldo kurang, di luar batas, dst.) |
+| `404` | 404 | Tidak ditemukan, juga untuk data milik customer atau organisasi lain |
+| `429` | 429 | OTP diminta ulang terlalu cepat |
+| `PIN_NOT_SET` | 403 | Customer belum membuat PIN |
+| `PIN_INVALID` | 400 | PIN salah |
+| `PIN_LOCKED` | 423 | PIN terkunci 30 menit setelah 5 kali salah |
+| `TRANSFER_BLOCKED` | 403 | Transfer ditahan 24 jam setelah reset PIN |
+| `900` | 500 | Kesalahan server |
+
+**Error PIN** membawa `data` yang tidak `null`: `{"code": "PIN_INVALID", "remaining_attempts": 3}`, `{"code": "PIN_LOCKED", "locked_until": "…"}`, atau `{"code": "TRANSFER_BLOCKED", "transfer_blocked_until": "…"}`. Endpoint yang menerima `pin` bisa mengembalikan salah satunya. PIN selalu dikirim sebagai string 6 digit.
+
+**Idempotency.** Exchange dan transfer wajib header `Idempotency-Key` (maks. 50 karakter, `X-Idempotency-Key` juga diterima): satu key per percobaan, dan key yang sama dipakai ulang saat retry. Retry mengembalikan hasil pertama dengan `replayed: true`. `POST /payments` wajib `X-Idempotency-Key` seperti pembayaran lain.
+
+**Waktu.** Tanggal kedaluwarsa dan filter tanggal memakai WIB. Saldo berlaku sampai 23:59:59 WIB pada tanggal kedaluwarsanya.
+
+## Customer app: saldo & riwayat
+
+| Method | Path | Keterangan |
+| --- | --- | --- |
+| GET | `/customer/wallet` | Saldo, nilai rupiah, kedaluwarsa terdekat, 5 mutasi terakhir |
+| GET | `/customer/wallet/transactions` | Riwayat mutasi, dengan pagination dan filter |
+| GET | `/customer/wallet/expiring` | Saldo yang akan kedaluwarsa, per currency dan tanggal |
+| PUT | `/customer/devices` | Daftarkan token FCM device |
+| DELETE | `/customer/devices/:device_id` | Hapus device saat logout |
+
+### GET /customer/wallet
+
+```json
+{
+  "point_balance": 12500,
+  "coin_balance": 8,
+  "point_value": 1,
+  "point_discount_value": 12500,
+  "nearest_expiring": {
+    "point": { "amount": 150, "date": "2026-12-31" },
+    "coin": null
+  },
+  "recent_transactions": [ "… sama seperti item riwayat …" ]
+}
+```
+
+- `point_balance` / `coin_balance` = saldo yang bisa dipakai sekarang.
+- `point_discount_value` = `point_balance × point_value`; tampilkan sebagai "setara potongan Rp …", bukan saldo uang.
+- `nearest_expiring.point` / `.coin` bernilai `null` bila tidak ada yang akan kedaluwarsa.
+
+### GET /customer/wallet/transactions
+
+| Query | Tipe | Keterangan |
+| --- | --- | --- |
+| `page` | int | Default 1 |
+| `limit` | int | 1–100, default 20 |
+| `currency` | `POINT` \| `COIN` | Opsional |
+| `type` | string | Satu tipe atau beberapa dipisah koma, mis. `EARN,PAYMENT` |
+| `from`, `to` | `YYYY-MM-DD` | Tanggal WIB, inklusif |
+
+```json
+{
+  "data": [
+    {
+      "id": "…",
+      "currency": "POINT",
+      "type": "EARN",
+      "amount": 875,
+      "balance_after": 12500,
+      "description": "Belanja #ORD-0123 di Outlet Kemang",
+      "source": { "type": "ORDER", "id": "…" },
+      "outlet_id": "…",
+      "group_id": null,
+      "expires_at": "2026-12-31T23:59:59+07:00",
+      "lots": [{ "amount": 875, "remaining": 875, "expires_at": "2026-12-31T23:59:59+07:00" }],
+      "created_at": "2026-09-30T12:01:00Z"
+    }
+  ],
+  "pagination": { "page": 1, "limit": 20, "total_count": 42, "total_pages": 3 }
+}
+```
+
+`amount` bertanda (+ menambah, − mengurangi). Penambahan membawa `source`, pengurangan membawa `destination`, keduanya `{ type, id }`. Dua baris exchange atau transfer berbagi `group_id`. Daftar tipe ada di bagian Referensi.
+
+### GET /customer/wallet/expiring
+
+```json
+{
+  "point": [
+    { "amount": 150, "date": "2026-10-31" },
+    { "amount": 200, "date": "2026-12-31" }
+  ],
+  "coin": []
+}
+```
+
+Terurut dari tanggal terdekat. Daftar kosong berarti tidak ada yang akan kedaluwarsa.
+
+### PUT /customer/devices
+
+```json
+{ "device_id": "a1b2c3", "fcm_token": "…", "platform": "android", "app_version": "2.4.0" }
+```
+
+Panggil setelah login dan setiap kali FCM memberi token baru. `device_id` dan `fcm_token` wajib; `platform` = `android` | `ios` | `web`. Satu token hanya milik satu customer: customer lain yang mendaftarkan token yang sama mengambil alih HP itu. Response: `{ "device_id": "a1b2c3" }`.
+
+## Customer app: PIN
+
+PIN 6 digit wajib untuk bayar, kode bayar, exchange, dan transfer; minta customer membuatnya saat pertama kali melakukan aksi itu.
+
+| Method | Path | Body | Response |
+| --- | --- | --- | --- |
+| GET | `/customer/pin/status` | – | `{ "has_pin", "locked_until", "transfer_blocked_until" }` |
+| POST | `/customer/pin/otp` | `{ "purpose": "pin_setup" }` atau `"pin_reset"` | `{ "purpose", "otp_token", "expires_at" }` |
+| POST | `/customer/pin` | `{ "otp_token", "otp_code", "pin", "confirm_pin" }` | Status PIN |
+| PUT | `/customer/pin` | `{ "old_pin", "pin", "confirm_pin" }` | Status PIN |
+| POST | `/customer/pin/reset` | `{ "otp_token", "otp_code", "pin", "confirm_pin" }` | Status PIN |
+
+1. **Buat PIN:** minta OTP dengan `purpose: "pin_setup"` (dikirim lewat WhatsApp), lalu `POST /customer/pin` dengan `otp_token` dari response OTP dan kode yang diterima customer.
+2. **Lupa PIN:** minta OTP dengan `purpose: "pin_reset"`, lalu `POST /customer/pin/reset`. Reset membuka kunci PIN, tapi transfer keluar ditahan 24 jam; pembayaran dan exchange tetap bisa.
+3. **Ganti PIN:** `PUT /customer/pin` dengan PIN lama.
+
+PIN baru ditolak `304` bila bukan 6 digit, konfirmasinya beda, semua digit sama (`111111`), berurutan (`123456`, `654321`), atau sama dengan tanggal lahir (`DDMMYY` / `YYMMDD`). OTP yang diminta terlalu cepat dijawab `429`. Penanganan `PIN_INVALID`, `PIN_LOCKED`, dan `TRANSFER_BLOCKED` ada di Konvensi umum.
+
+## Customer app: bayar, exchange, transfer, game
+
+| Method | Path | PIN | Idempotency-Key |
+| --- | --- | --- | --- |
+| POST | `/customer/wallet/payment-code` | Ya | – |
+| POST | `/customer/orders/:id/pay-with-points` | Ya | – |
+| GET | `/customer/wallet/exchange/preview?coins=` | – | – |
+| POST | `/customer/wallet/exchange` | Ya | Wajib |
+| GET | `/customer/wallet/transfer/recipient?phone=` | – | – |
+| POST | `/customer/wallet/transfer` | Ya | Wajib |
+| POST | `/customer/spin` | – | – |
+
+### POST /customer/wallet/payment-code
+
+Body `{ "pin": "482913" }`. Response:
+
+```json
+{ "code": "482913", "qr_payload": "enakpoint:482913", "expires_at": "2026-09-30T05:02:00Z" }
+```
+
+Tampilkan `code` sebagai angka dan `qr_payload` sebagai QR untuk kasir. Berlaku 2 menit, sekali pakai, hanya untuk customer ini; kode baru membatalkan kode lama.
+
+### POST /customer/orders/:id/pay-with-points
+
+Body `{ "points": 12500, "pin": "482913" }`. Hanya untuk order milik customer yang login (order lain `404`). Response sama dengan pembayaran POS (bagian POS). Batas dan aturan penolakan juga sama.
+
+### GET /customer/wallet/exchange/preview?coins=30
+
+```json
+{ "coin_amount": 10, "point_amount": 3, "coin_balance": 35, "coins": 30, "points": 9, "valid": true }
+```
+
+Kurs: `coin_amount` EnakCoin = `point_amount` EnakPoint (default 1 : 1). Bila `valid: false`, tampilkan `reason`.
+
+### POST /customer/wallet/exchange
+
+Body `{ "coins": 30, "pin": "482913" }`. Response:
+
+```json
+{
+  "group_id": "…",
+  "coins": 30,
+  "points": 9,
+  "coin_amount": 10,
+  "point_amount": 3,
+  "lots": [{ "amount": 9, "expires_at": "2026-12-31T23:59:59+07:00" }],
+  "coin_balance": 5,
+  "point_balance": 9,
+  "replayed": false
+}
+```
+
+`coins` harus kelipatan `coin_amount`; jumlah yang salah ditolak `304` sebelum PIN dicek. Exchange tidak bisa dibatalkan. EnakPoint hasil tukar tidak bisa hidup lebih lama dari EnakCoin asalnya (lihat `lots`).
+
+### GET /customer/wallet/transfer/recipient?phone=081234561234
+
+```json
+{ "name": "Bu*** Sa***", "phone_number": "08**-****-1234" }
+```
+
+Nomor di luar organisasi atau tidak terdaftar → `404`. Diri sendiri, customer walk-in, atau nonaktif → `304`.
+
+### POST /customer/wallet/transfer
+
+Body `{ "currency": "POINT", "amount": 120, "recipient_phone": "081234561234", "pin": "482913" }`. Response:
+
+```json
+{
+  "group_id": "…",
+  "currency": "POINT",
+  "amount": 120,
+  "recipient": { "name": "Bu*** Sa***", "phone_number": "08**-****-1234" },
+  "lots": [
+    { "amount": 100, "expires_at": "2026-12-31T23:59:59+07:00" },
+    { "amount": 20, "expires_at": null }
+  ],
+  "balance": 30,
+  "replayed": false
+}
+```
+
+`currency` = `POINT` atau `COIN`. Batas organisasi (transfer aktif, minimal, maksimal per transaksi, batas harian per currency yang reset tengah malam WIB) ditolak `304` sebelum PIN dicek. Transfer final. Saldo membawa tanggal kedaluwarsa aslinya ke penerima (`lots`), dan penerima mendapat push `WALLET_TRANSFER_IN`.
+
+### POST /customer/spin
+
+Body `{ "spin_id": "<id game>" }`. Memotong EnakCoin sebesar `metadata.coin_cost` game itu (default 1).
+
+```json
+{
+  "game_play": { "id": "…", "game_id": "…", "coins_used": 1, "created_at": "…" },
+  "prize_won": { "id": "…", "name": "Voucher 10rb" },
+  "coins_remaining": 7
+}
+```
+
+EnakCoin kurang, game nonaktif, atau hadiah baru saja habis → `304`, tidak ada EnakCoin yang terpotong.
+
+## POS: pembayaran EnakPoint
+
+Kasir memakai endpoint pembayaran yang sudah ada dengan payment method bertipe `point`, disetujui customer lewat kode bayar dari aplikasinya; PIN tidak pernah diketik di perangkat kasir.
+
+| Method | Path | Keterangan |
+| --- | --- | --- |
+| GET | `/orders/:id/point-payment/preview` | Batas pembayaran EnakPoint untuk order ini |
+| POST | `/payments` | Bayar dengan method EnakPoint (`points` + `payment_code`) |
+| POST | `/payments/:id/refund` | Refund pembayaran EnakPoint, kembali sebagai EnakPoint |
+
+1. Customer membuat kode di aplikasi (`POST /customer/wallet/payment-code`) dan menunjukkan angka atau QR-nya.
+2. POS memanggil preview untuk tombol "pakai maksimal".
+3. POS memanggil `POST /payments` dengan kode tersebut. Sisa tagihan dibayar dengan method lain seperti biasa.
+
+### GET /orders/:id/point-payment/preview
+
+```json
+{
+  "order_id": "…",
+  "customer_id": "…",
+  "eligible": true,
+  "point_balance": 12500,
+  "point_value": 1,
+  "remaining_amount": 87500,
+  "min_payment_points": 1,
+  "max_payment_percent": 100,
+  "max_points": 12500,
+  "max_amount": 12500
+}
+```
+
+Bila `eligible: false`, `reason` menjelaskan kenapa (order walk-in, outlet tidak menerima EnakPoint, saldo di bawah minimal, dst.). Batas yang dipakai:
+
+```
+batas_rupiah = min(sisa_tagihan, total × max_payment_percent / 100 − sudah_dibayar_EnakPoint)
+maks_point   = min(saldo, floor(batas_rupiah / point_value))
+```
+
+### POST /payments
+
+Header `X-Idempotency-Key` wajib.
+
+```json
+{
+  "order_id": "…",
+  "payment_method_id": "<id method EnakPoint>",
+  "points": 12500,
+  "payment_code": "482913"
+}
+```
+
+- `amount` tidak perlu dikirim; backend menghitung `points × point_value` dan tidak pernah melebihi sisa tagihan (tidak ada kembalian).
+- `payment_code` boleh angka yang diketik atau hasil scan QR apa adanya (`enakpoint:482913`).
+- Response pembayaran membawa `points_used` dan `point_value` untuk struk; response order membawa `points_earned` dan `coins_earned`.
+- Ditolak `304` bila: order tanpa customer atau walk-in, customer nonaktif, outlet tidak menerima EnakPoint, `points` di luar batas, kode salah/kedaluwarsa/sudah dipakai/milik customer lain, atau method EnakPoint dipakai sebagai split. Kode terpakai begitu diterima; bila pembayaran lalu ditolak, minta kode baru.
+- Method EnakPoint dibuat otomatis per organisasi, tidak bisa dihapus atau diubah tipenya, dan tidak muncul di daftar method `?outlet_id=` bila outlet tidak menerima EnakPoint.
+
+### Void dan refund
+
+- **Void order:** semua EnakPoint yang dipakai kembali sebagai EnakPoint.
+- **`POST /payments/:id/refund` pada pembayaran EnakPoint:** kembali `floor(rupiah_direfund / point_value_saat_bayar)`; sisa di bawah 1 EnakPoint hangus.
+- **Refund order ke tunai/method lain** hanya sebesar bagian non-EnakPoint; mencoba merefund bagian EnakPoint secara tunai ditolak `304`.
+- EnakPoint yang kembali memakai tanggal kedaluwarsa asal, minimal 7 hari sejak refund. Earning order ikut ditarik; bila saldo sudah terpakai, ditarik sebanyak yang ada dan refund tetap jalan.
+
+## Dashboard
+
+Semua endpoint dashboard butuh role Admin atau Manager, dan semuanya dibatasi ke organisasi user yang login. Rincian layar ada di [`backoffice-enakpoint.md`](./backoffice-enakpoint.md).
+
+| Method | Path | Keterangan |
+| --- | --- | --- |

+# Backoffice EnakPoint & EnakCoin
+
+30 Sep 2026
+
+Backoffice perlu tujuh layar untuk mengelola program loyalitas: setting per outlet, setting per organisasi (termasuk kedaluwarsa), wallet customer, telusuri mutasi, PIN customer, riwayat setting, dan biaya main game.
+
+## Layar yang perlu dibuat
+
+Semua endpoint di bawah base URL `/api/v1`, butuh login user dengan role Admin atau Manager, dan otomatis dibatasi ke organisasi user tersebut. Data customer atau outlet organisasi lain dijawab `404`.
+
+| Layar | Endpoint | Tempat di menu |
+| --- | --- | --- |
+| Setting loyalitas outlet | `GET` / `PUT /outlets/:outlet_id/loyalty-settings` | Outlet → detail outlet → tab Loyalitas |
+| Setting loyalitas organisasi | `GET` / `PUT /marketing/loyalty-settings` (+ `?dry_run=true`) | Marketing → Loyalitas → Pengaturan |
+| Riwayat perubahan setting | `GET /marketing/loyalty-settings/history` | Marketing → Loyalitas → Riwayat |
+| Wallet customer | `GET /marketing/customers/:id/wallet`, `POST …/wallet/adjust` | Customer → detail customer → tab Wallet |
+| Telusuri mutasi | `GET /marketing/wallet-transactions/:id/trace` | Dibuka dari baris riwayat wallet |
+| PIN & keamanan customer | `DELETE /marketing/customers/:id/pin`, `GET …/security-events` | Customer → detail customer → tab Keamanan |
+| Biaya main game | `PUT` game yang sudah ada, `metadata.coin_cost` | Marketing → Game → edit game |
+
+Penempatan menu di atas adalah usulan; sesuaikan dengan struktur backoffice yang ada.
+
+**Istilah di layar.** EnakPoint (`POINT`) adalah saldo yang bisa membayar order; EnakCoin (`COIN`) untuk main game dan bisa ditukar ke EnakPoint. Nilai rupiah EnakPoint selalu ditulis "setara potongan Rp …", tidak pernah "saldo Rp …", karena saldo tidak bisa dicairkan.
+
+**Format response.** Sukses `{ "success": true, "data": … }`; gagal `{ "success": false, "errors": [{ "code", "entity", "cause" }] }`. Tampilkan `cause` sebagai pesan (lihat bagian Pesan error).
+
+## Setting loyalitas outlet
+
+Tiap outlet mengatur sendiri berapa EnakPoint dan EnakCoin yang didapat dari order, dan apakah outlet menerima pembayaran EnakPoint. Semua nilai default mati sampai owner menyalakannya.
+
+`GET /outlets/:outlet_id/loyalty-settings` → isi form. `PUT` ke path yang sama dengan objek yang sama untuk menyimpan; field yang tidak dikirim tetap, field tak dikenal ditolak.
+
+```json
+{
+  "point": { "enabled": true, "earn_per_amount": 100, "earn_value": 1, "min_order_amount": 0, "max_per_order": null },
+  "coin": { "enabled": true, "earn_per_amount": 25000, "earn_value": 1, "min_order_amount": 0, "max_per_order": null },
+  "point_payment": { "accept_payment": true, "min_payment_points": 1, "max_payment_percent": 100 }
+}
+```
+
+| Field | Label usulan | Tipe | Default | Validasi |
+| --- | --- | --- | --- | --- |
+| `point.enabled` / `coin.enabled` | Beri EnakPoint / EnakCoin | toggle | mati | – |
+| `earn_per_amount` | Setiap belanja Rp … | Rp | 100 (point), 25.000 (coin) | > 0 |
+| `earn_value` | … mendapat | angka | 1 | ≥ 0 |
+| `min_order_amount` | Minimal belanja | Rp | 0 | ≥ 0 |
+| `max_per_order` | Maksimal per order | angka, boleh kosong | kosong = tanpa batas | ≥ 0 |
+| `point_payment.accept_payment` | Terima pembayaran EnakPoint | toggle | mati | – |
+| `min_payment_points` | Minimal EnakPoint per pembayaran | angka | 1 | ≥ 1 |
+| `max_payment_percent` | Maksimal porsi order dibayar EnakPoint | % | 100 | 0–100 |
+
+**Cashback efektif.** Response membawa `point_cashback_percent` dan `point_value`. Tampilkan persentase di samping field earning EnakPoint, mis. "setara cashback 1%", dan hitung ulang di sisi klien saat owner mengetik: `earn_value × point_value ÷ earn_per_amount × 100`. Tujuannya agar owner tidak salah membaca skala (1 per Rp 100 bukan 1 per Rp 1).
+
+**Contoh di bawah form.** "Belanja Rp 87.500 mendapat 875 EnakPoint dan 3 EnakCoin." Earning dihitung dari subtotal setelah diskon, sebelum pajak, dan bagian yang dibayar EnakPoint tidak ikut dihitung.
+
+Setelah `PUT`, response membawa `changes` (key yang berubah); tampilkan toast singkat, mis. "2 pengaturan disimpan". Mematikan `accept_payment` langsung menyembunyikan method EnakPoint di kasir outlet itu.
+
+## Setting loyalitas organisasi
+
+Nilai rupiah EnakPoint, kurs exchange, batas transfer, dan kedaluwarsa berlaku sama untuk semua outlet, jadi diatur sekali per organisasi. Mengubah nilai EnakPoint atau kurs langsung mengubah daya beli semua saldo customer, jadi layar ini wajib menampilkan dampaknya sebelum disimpan.
+
+```json
+{
+  "point_value": 1,
+  "exchange": { "coin_amount": 1, "point_amount": 1 },
+  "transfer": { "enabled": true, "min_amount": 1, "max_per_transaction": null, "daily_limit": null },
+  "point_expiry": { "…": "lihat bagian kedaluwarsa" },
+  "coin_expiry": { "…": "lihat bagian kedaluwarsa" }
+}
+```
+
+| Field | Label usulan | Default | Validasi |
+| --- | --- | --- | --- |
+| `point_value` | Nilai 1 EnakPoint (Rp) | 1 | ≥ 1 |
+| `exchange.coin_amount` : `exchange.point_amount` | Kurs tukar: … EnakCoin = … EnakPoint | 1 : 1 | keduanya ≥ 1 |
+| `transfer.enabled` | Izinkan transfer antar customer | aktif | – |
+| `transfer.min_amount` | Minimal per transfer | 1 | ≥ 1 |
+| `transfer.max_per_transaction` | Maksimal per transfer | kosong = tanpa batas | ≥ 1 |
+| `transfer.daily_limit` | Batas harian per customer | kosong = tanpa batas | ≥ 1, dihitung per currency, reset tengah malam WIB |
+
+### Alur simpan
+
+1. Owner mengubah form.
+2. Tombol Simpan memanggil `PUT /marketing/loyalty-settings?dry_run=true` dengan objek yang diubah. Tidak ada yang tersimpan.
+3. Bila `changes` kosong, beri tahu "tidak ada perubahan" dan berhenti.
+4. Tampilkan dialog konfirmasi berisi `changes`, `impact` (bila `point_value` atau kurs berubah), dan `expiry_activations` (bila ada, lihat bagian kedaluwarsa).
+5. Konfirmasi memanggil `PUT` yang sama tanpa `dry_run`.
+
+### Dialog dampak
+
+`impact` berisi saldo beredar organisasi dan nilainya sebelum/sesudah:
+
+| Field `impact` | Tampilkan sebagai |
+| --- | --- |
+| `outstanding_points` | EnakPoint beredar |
+| `point_rupiah_before` → `point_rupiah_after` | Setara potongan Rp … → Rp … |
+| `outstanding_coins` | EnakCoin beredar |
+| `coins_as_points_before` → `coins_as_points_after` | Bila semua ditukar: … EnakPoint → … EnakPoint |
+| `coin_rupiah_before` → `coin_rupiah_after` | Setara potongan Rp … → Rp … |
+
+Contoh kalimat: "Menaikkan nilai EnakPoint dari Rp 1 ke Rp 2 membuat 1.250.000 EnakPoint yang beredar setara potongan Rp 2.500.000 (sebelumnya Rp 1.250.000)." Perubahan hanya berlaku ke depan: pembayaran, refund, dan exchange yang sudah terjadi memakai nilai saat itu.
+
+## Pengaturan kedaluwarsa
+
+Kedaluwarsa diatur terpisah untuk EnakPoint (`point_expiry`) dan EnakCoin (`coin_expiry`) dengan salah satu dari dua model; defaultnya mati, dan bila dinyalakan defaultnya hangus setiap 31 Desember.
+
+```json
+"point_expiry": {
+  "enabled": true,
+  "mode": "FIXED_DATE",
+  "fixed_dates": ["12-31"],
+  "grace_months": 3,
+  "period": 12,
+  "unit": "MONTH",
+  "end_of_month": false,
+  "reminder_days": 7
+}
+```
+
+| Field | Tampil saat | Label usulan | Validasi |
+| --- | --- | --- | --- |
+| `enabled` | selalu | Saldo bisa kedaluwarsa | – |
+| `mode` | aktif | Model: Tanggal tetap / Sejak didapat | `FIXED_DATE` atau `ROLLING` |
+| `fixed_dates` | `FIXED_DATE` | Tanggal hangus setiap tahun | minimal satu, format `MM-DD`, `02-29` ditolak |
+| `grace_months` | `FIXED_DATE` | Periode tanggung (bulan) | 0–24, default 3 |
+| `period` + `unit` | `ROLLING` | Berlaku selama … hari/bulan | period ≥ 1, `DAY` atau `MONTH` |
+| `end_of_month` | `ROLLING` | Bulatkan ke akhir bulan | – |
+| `reminder_days` | aktif | Ingatkan customer … hari sebelumnya | ≥ 0, 0 = tanpa pengingat |
+
+**Tanggal tetap (`FIXED_DATE`).** Semua saldo hangus di tanggal yang sama, mis. 31 Desember, atau 30 Juni dan 31 Desember untuk dua kali setahun. Saldo yang didapat kurang dari `grace_months` sebelum tanggal itu ikut ke tanggal berikutnya, jadi saldo yang didapat 1 Oktober dengan tanggung 3 bulan hangus 31 Desember tahun depan. Untuk input `fixed_dates`, pakai pemilih tanggal+bulan tanpa tahun.
+
+**Sejak didapat (`ROLLING`).** Tiap saldo berlaku `period` hari atau bulan sejak masuk, mis. 12 bulan. Dengan `end_of_month`, saldo yang didapat 14 Maret 2026 hangus 31 Maret 2027.
+
+**Preview.** Response `GET`, `PUT`, dan dry run membawa `expiry_preview.point` dan `.coin`: kapan saldo yang didapat sekarang akan kedaluwarsa (`null` = tidak). Tampilkan di bawah form: "EnakPoint yang didapat hari ini kedaluwarsa pada 31 Des 2026." Karena dihitung dari nilai yang dikirim, dry run bisa dipakai untuk memperbarui preview saat owner mengubah pilihan.
+
+**Menyalakan pertama kali.** Saldo lama yang belum punya tanggal ikut diberi tanggal, dengan masa berlaku penuh: tanggal hangus kedua berikutnya (`FIXED_DATE`) atau satu periode sejak hari ini (`ROLLING`). Dry run mengembalikan `expiry_activations`; tampilkan di dialog konfirmasi dengan kalimat tegas, mis. "1.250.000 EnakPoint milik customer yang ada sekarang akan kedaluwarsa pada 31 Des 2027. Tindakan ini tidak bisa dibatalkan dengan mematikan kedaluwarsa."
+
+| Field `expiry_activations[]` | Arti |
+| --- | --- |
+| `currency` | `POINT` atau `COIN` |
+| `lots` | Jumlah paket saldo yang diberi tanggal |
+| `amount` | Total saldo yang diberi tanggal |
+| `expires_at` | Tanggal kedaluwarsanya |
+
+**Aturan lain yang perlu dijelaskan di layar:**
+
+- Mengubah model atau masa berlaku hanya berlaku untuk saldo yang masuk setelahnya.
+- Mematikan kedaluwarsa tidak membatalkan tanggal yang sudah terjadwal.
+- Saldo yang ditransfer atau ditukar membawa tanggal kedaluwarsa aslinya.
+- Saldo hangus tanpa kompensasi apa pun. Customer mendapat pengingat push `reminder_days` hari sebelumnya dan notifikasi saat hangus.
+
+## Wallet customer
+
+Tab Wallet di detail customer dipakai untuk menangani komplain: melihat saldo dan asal-usulnya, mengoreksi saldo, dan menelusuri satu mutasi sampai ke order asalnya.
+
+### Saldo, lot, dan riwayat
+
+`GET /marketing/customers/:id/wallet?page=1&limit=20&currency=POINT&type=PAYMENT,EARN&from=2026-09-01&to=2026-09-30` (semua query opsional, sama seperti riwayat di aplikasi customer)
+
+```json
+{
+  "customer": { "id": "…", "name": "Budi Santoso", "phone": "081234561234" },
+  "point_balance": 12650,
+  "coin_balance": 8,
+  "spendable_point_balance": 12500,
+  "spendable_coin_balance": 8,
+  "lots": [
+    { "id": "…", "currency": "POINT", "original_amount": 875, "remaining_amount": 875, "expires_at": "2026-12-31T23:59:59+07:00", "expired": false, "source_transaction_id": "…", "origin_lot_id": null, "created_at": "…" }
+  ],
+  "transactions": {
+    "data": [
+      {
+        "id": "…", "currency": "POINT", "type": "TRANSFER_OUT", "amount": -120, "balance_after": 12650,
+        "description": "Transfer ke An*** (08**-****-5678)",
+        "destination": { "type": "WALLET_TX", "id": "…" },

+        "created_by": null, "outlet": null, "reason": null, "metadata": {},
+        "created_at": "…"
+      }
+    ],
+    "pagination": { "page": 1, "limit": 20, "total_count": 42, "total_pages": 3 }
+  }
+}
+```
+
+- **Saldo:** tampilkan `spendable_*` sebagai saldo utama. `point_balance` / `coin_balance` bisa sedikit lebih besar selama ada lot yang sudah lewat tanggal tapi belum diproses job kedaluwarsa (paling lama sekitar 15 menit).
+- **Lot:** tabel paket saldo yang masih berisi, urut dari yang paling cepat kedaluwarsa. Beri tanda untuk `expired: true`.
+- **Riwayat:** sama dengan riwayat customer, ditambah nama asli yang disamarkan untuk customer: `counterparty` (lawan transfer), `created_by` (admin pelaku adjustment atau kasir penerima pembayaran), `outlet`, `reason`, dan `metadata` (kurs, nilai EnakPoint yang dibekukan, shortfall).
+
+### Adjustment manual
+
+`POST /marketing/customers/:id/wallet/adjust`
+
+```json
+{ "currency": "POINT", "amount": -500, "reason": "Komplain #45", "idempotency_key": "adj-7f3c" }
+```
+
+| Field | Aturan |
+| --- | --- |
+| `currency` | `POINT` atau `COIN` |
+| `amount` | Bertanda, tidak boleh 0. Positif menambah, negatif mengurangi |
+| `reason` | Wajib; tampil di riwayat customer sebagai "Koreksi oleh admin: …" |
+| `idempotency_key` | Opsional tapi disarankan: buat satu nilai saat dialog dibuka, supaya klik ganda tidak mengoreksi dua kali |
+
+Pengurangan yang melebihi saldo yang bisa dipakai ditolak `304`. Adjustment tambah mengikuti aturan kedaluwarsa organisasi. Response: `{ "transaction", "spendable_point_balance", "spendable_coin_balance", "replayed" }`. Beri catatan di dialog bahwa adjustment tidak disertai pembayaran uang, sehingga alasan tidak boleh "pencairan".
+
+### Telusuri mutasi
+
+Dari baris riwayat mana pun, tombol Telusuri memanggil `GET /marketing/wallet-transactions/:id/trace`.
+
+```json
+{
+  "transaction": { "id": "…", "customer": { "id": "…", "name": "Budi Santoso" }, "currency": "POINT", "type": "PAYMENT", "amount": -30, "description": "Bayar #ORD-0456 di Outlet Kemang (Rp 30)", "reference_type": "PAYMENT", "reference_id": "…", "created_at": "…" },
+  "lots": [
+    {
+      "amount": 30,
+      "chain": [
+        { "lot": { "id": "…", "expires_at": "…", "origin_lot_id": "…" }, "source": { "type": "TRANSFER_IN", "customer": { "name": "Budi Santoso" }, "description": "Transfer dari An*** (08**-****-5678)" } },
+        { "lot": { "id": "…", "origin_lot_id": null }, "source": { "type": "EARN", "customer": { "name": "Anita Rahma" }, "reference_type": "ORDER", "reference_id": "…", "description": "Belanja #ORD-1 di Outlet Kemang" } }
+      ]
+    }
+  ]
+}
+```
+
+Tampilkan tiap `lots[]` sebagai rantai dari atas ke bawah: jumlah yang lewat lot itu, lalu setiap langkah `chain` dengan pemilik, tipe, dan deskripsinya. Langkah terakhir selalu `EARN`, `ADJUSTMENT`, atau `MIGRATION`; bila `reference_type` = `ORDER`, jadikan tautan ke detail order. Mutasi keluar menampilkan lot yang dipakai; mutasi masuk menampilkan lot yang dibuatnya.
+
+## PIN, riwayat setting, game, dan method EnakPoint
+
+### PIN & keamanan customer
+
+Admin tidak bisa membuat, mengganti, atau melihat PIN customer; satu-satunya aksi adalah menghapusnya, misalnya bila customer kehilangan akses, sehingga customer harus membuat PIN baru lewat OTP di aplikasi.
+
+- `DELETE /marketing/customers/:id/pin` dengan body `{ "reason": "Customer ganti nomor HP" }`. `reason` wajib. Tampilkan dialog konfirmasi dengan input alasan.
+- `GET /marketing/customers/:id/security-events?page=1&limit=20` untuk tab Keamanan:
+
+```json
+{
+  "data": [
+    { "id": "…", "event": "PIN_LOCKED", "actor_user": null, "reason": null, "ip_address": "103.10.0.7", "user_agent": "EnakApp/2.4 (Android 14)", "created_at": "…" }
+  ],
+  "pagination": { "page": 1, "limit": 20, "total_count": 5, "total_pages": 1 }
+}
+```
+
+| `event` | Label usulan |
+| --- | --- |
+| `PIN_SET` | PIN dibuat |
+| `PIN_CHANGED` | PIN diganti |
+| `PIN_RESET` | PIN direset lewat OTP (transfer ditahan 24 jam) |
+| `PIN_FAILED` | PIN salah dimasukkan |
+| `PIN_LOCKED` | PIN terkunci 30 menit |
+| `PIN_REMOVED_BY_ADMIN` | PIN dihapus admin (`actor_user`, `reason` terisi) |
+
+### Riwayat perubahan setting
+
+`GET /marketing/loyalty-settings/history?page=1&limit=20` untuk setting organisasi; tambah `&outlet_id=…` untuk riwayat satu outlet.
+
+```json
+{ "id": "…", "organization_id": "…", "outlet_id": null, "key": "loyalty.point.value", "old_value": "1", "new_value": "2", "changed_by": "…", "created_at": "…" }
+```
+
+`old_value` `null` berarti sebelumnya masih nilai default. Tampilkan `key` dengan label yang sama seperti di form (mis. `loyalty.point.value` → "Nilai 1 EnakPoint"), dan `changed_by` sebagai nama user.
+
+### Biaya main game
+
+Semua game (spin, raffle, minigame) memakai EnakCoin yang sama. Biaya per main diisi di `metadata.coin_cost` saat membuat atau mengedit game (`/marketing/games`): bilangan bulat ≥ 1, default 1 bila kosong. Nilai pecahan, 0, atau teks membuat game tidak bisa dimainkan. Karena `metadata` dikirim utuh, pertahankan key metadata lain saat menyimpan. Hadiah game juga bernilai rupiah secara tidak langsung, karena EnakCoin bisa ditukar ke EnakPoint.
+

+# Migrasi printer_type ke printer_types
+
+1 Oktober 2026
+
+## Ringkasan
+
+`printer_type` (string) dihapus dan diganti `printer_types` (array string), sehingga satu produk bisa dicetak ke lebih dari satu printer. Contohnya "Paket Makan Minum" dengan `["kitchen", "bar"]` tercetak di kitchen dan bar sekaligus.
+
+Ini breaking change. Setelah backend baru dirilis, client yang masih membaca `printer_type` tidak menerima printer apa pun. Karena itu app POS dan dashboard harus diupdate lebih dulu, lihat [Urutan rilis](#database-dan-urutan-rilis).
+
+Yang perlu bertindak:
+
+- **App POS**: baca `printer_types` dan cetak tiap item ke semua printer di dalamnya.
+- **Dashboard admin**: ganti pilihan printer di form produk jadi multi-select yang mengirim `printer_types`.
+
+## Perubahan response
+
+`printer_type` hilang dari semua response dan digantikan `printer_types`, yang nilainya selalu array dan tidak pernah `null`.
+
+| Endpoint | Letak field |
+| --- | --- |
+| `POST /api/v1/products`, `PUT /api/v1/products/:id`, `GET /api/v1/products`, `GET /api/v1/products/all`, `GET /api/v1/products/:id` | objek produk |
+| `POST /api/v1/orders`, `GET /api/v1/orders`, `GET /api/v1/orders/:id`, `PUT /api/v1/orders/:id` | `order_items[]` |
+| `POST /api/v1/orders/:id/add-items` | `added_items[]` dan `updated_order.order_items[]` |
+| `POST /api/v1/self-order/orders`, `GET /api/v1/self-order/orders/:session_id` | `order_items[]` |
+| `/api/v1/product-recipes` (semua yang mengembalikan recipe) | `product` |
+| `/api/v1/inventory` | `product`, selalu `[]` karena produk di sini hanya berisi id dan nama |
+
+Contoh satu item di `order_items[]`:
+
+```json
+{
+  "product_name": "Paket Makan Minum",
+  "printer_types": ["kitchen", "bar"],
+  "print_to_checker": true
+}
+```
+
+Aturan nilainya:
+
+- `printer_types: []` artinya produk tidak dicetak ke printer mana pun.
+- Urutan printer sesuai yang disimpan admin, tanpa duplikat.
+- Void, refund, payment, split bill, dan set customer tidak membawa data printer, sama seperti sebelumnya.
+
+## Perubahan request produk
+
+`POST /api/v1/products` dan `PUT /api/v1/products/:id` menerima `printer_types` sebagai pengganti `printer_type`. Kalau `printer_type` masih dikirim, field itu diabaikan tanpa error.
+
+```json
+{
+  "name": "Paket Makan Minum",
+  "category_id": "<uuid>",
+  "price": 25000,
+  "printer_types": ["kitchen", "bar"]
+}
+```
+
+| Request | `printer_types` yang dikirim | Hasil |
+| --- | --- | --- |
+| Create | tidak dikirim | `["kitchen"]` |
+| Create | `["kitchen", "bar"]` | `["kitchen", "bar"]` |
+| Create | `[]` atau hanya string kosong | `["kitchen"]` |
+| Update | tidak dikirim | tidak berubah |
+| Update | `["bar"]` | `["bar"]`, seluruh daftar diganti |
+| Update | `[]` | `[]`, produk tidak dicetak ke mana pun |
+
+Sebelum disimpan, spasi di awal dan akhir tiap entri dibuang, lalu entri kosong dan duplikat dihapus. Urutan dipertahankan.
+
+Tiap entri maksimal 50 karakter. Kalau lebih, request ditolak dengan error code `310` dan pesan `each printer_types entry cannot exceed 50 characters`.
+
+## Migrasi app POS
+
+App POS harus mengirim tiap item ke semua printer di `printer_types`, sehingga satu item bisa muncul di lebih dari satu tiket.
+
+1. Ganti `printer_type` dengan `printer_types` (list string) di model order item dan produk.
+2. Selama backend lama masih jalan, `printer_types` belum ada di response. Pakai `[printer_type]` kalau `printer_types` tidak ada, supaya app baru bisa dirilis sebelum backend.
+3. Saat mencetak, kelompokkan item per printer dengan mengulang setiap entri `printer_types` milik item.
+4. Item dengan `printer_types: []` tidak dicetak ke printer station mana pun.
+5. `print_to_checker` tidak berubah dan tetap diperlakukan terpisah.
+6. Untuk tambahan pesanan dari `POST /api/v1/orders/:id/add-items`, cetak dari `added_items[]`.
+
+```text
+tiket = {}
+untuk setiap item di order_items:
+    printers = item.printer_types ?? [item.printer_type]   // fallback hanya untuk backend lama
+    untuk setiap printer di printers:
+        tiket[printer].tambah(item)
+untuk setiap (printer, items) di tiket:
+    cetak items ke printer
+```
+
+Perbaikan di `added_items[]`: sebelumnya field ini selalu berisi `product_name` dan printer kosong, serta `print_to_checker: true`. Sekarang isinya lengkap seperti item di `updated_order.order_items[]`, dengan urutan sesuai request. Kalau app selama ini mengakali dengan mencari item baru di `updated_order`, cara itu bisa diganti dengan `added_items[]` langsung.
+
+## Migrasi dashboard
+
+Form produk di dashboard harus memakai multi-select printer dan selalu mengirim daftar lengkapnya lewat `printer_types`.
+
+1. Ganti dropdown printer tunggal dengan multi-select, misalnya checkbox, berisi pilihan printer yang sama.
+2. Saat membuka form edit, isi pilihan dari `printer_types`. Selama backend lama masih jalan, pakai `[printer_type]` kalau `printer_types` tidak ada.
+3. Saat menyimpan, kirim `printer_types` berisi semua printer yang dipilih.
+4. Selama backend lama masih jalan, kirim juga `printer_type` berisi printer pertama. Backend lama hanya membaca `printer_type`, dan backend baru mengabaikannya.
+5. Di daftar produk, tampilkan semua printer dari `printer_types`.
+
+Backend tidak membatasi nilai printer. Nilainya harus sama persis dengan nama printer yang dikenal app POS, termasuk huruf besar dan kecilnya.
+
+Create dengan `printer_types: []` tetap menghasilkan `["kitchen"]`. Produk tanpa printer dibuat dulu, lalu di-update dengan `printer_types: []`.
+
+## Database dan urutan rilis
+
+Migration `000099_add_printer_types_to_products` menambah kolom `products.printer_types` (JSONB, `NOT NULL`, default `["kitchen"]`), mengisinya dari `printer_type`, lalu menghapus kolom `printer_type` beserta index-nya.
+
+- Produk dengan `printer_type` berisi nilai menjadi `[printer_type]`.
+- Produk dengan `printer_type` `NULL` atau kosong menjadi `[]`.
+
+Urutan rilis:
+
+1. Rilis app POS baru, yang membaca `printer_types` dengan fallback ke `printer_type`, ke semua outlet.
+2. Rilis dashboard baru, yang mengirim `printer_types` dan `printer_type`.
+3. Jalankan migration `000099` tepat sebelum deploy backend baru. Di antara keduanya, backend lama gagal menyimpan produk karena kolom `printer_type` sudah tidak ada.
+4. Setelah backend baru jalan, dashboard boleh berhenti mengirim `printer_type`, dan fallback di app POS boleh dihapus.
+5. Atur produk multi-printer, misalnya "Paket Makan Minum" ke `["kitchen", "bar"]`.
+
+Outlet yang masih memakai app POS lama setelah langkah 3 tidak menerima printer untuk semua item. Pastikan langkah 1 sudah selesai di semua outlet.
+
+Rollback: jalankan down migration dan deploy backend lama bersamaan. Down migration membuat ulang kolom `printer_type` berisi printer pertama, lalu menghapus `printer_types`, jadi yang hilang hanya printer tambahan.
+
+## Checklist
+
+- [ ] App POS baru (dengan fallback) terpasang di semua outlet
+- [ ] Dashboard baru mengirim `printer_types` dan `printer_type`
+- [ ] Migration `000099` dan backend baru dirilis di staging
+- [ ] Uji "Paket Makan Minum" dengan `["kitchen", "bar"]` tercetak di dua printer, saat order baru dan saat tambah pesanan
+- [ ] Migration `000099` dan backend baru dirilis di production
+- [ ] Dashboard berhenti mengirim `printer_type`
+- [ ] Fallback `printer_type` di app POS dihapus
+
+## FAQ
+
+**Kenapa `printer_type` dihapus, bukan dipertahankan?** Supaya hanya ada satu sumber data printer. Dua field yang menyimpan hal yang sama bisa saling berbeda.
+
+**Apakah kitchen dan bar menerima tiket yang sama?** Ya. Keduanya mencetak "Paket Makan Minum" lengkap dengan varian dan modifier-nya. Memecah isi paket per station butuh fitur bundle, yang di luar rilis ini.
+
+**Apakah nilai printer dibatasi?** Tidak. Nilainya string bebas sampai 50 karakter, dan harus sama dengan nama printer di app POS.

+- **Selesai jika:** up/down bersih.
+- **Bergantung pada:** –
+
+### PC-103 · Entities dan repository wallet · M
+- **PRD:** §7.1–§7.4
+- **Kerjakan:**
+  - Entities untuk empat tabel PC-101.
+  - Repository yang **selalu** memakai `DBFromContext` (berbeda dari repository
+    gamification yang sekarang memakai `r.db` langsung).
+  - `LockWallet(ctx, customerID)` dengan `SELECT … FOR UPDATE`. Membuat baris wallet
+    jika belum ada (`INSERT … ON CONFLICT DO NOTHING`, lalu lock).
+  - `LockWallets(ctx, a, b)` yang selalu mengunci berurutan berdasarkan `customer_id`.

+  saldo:
+  - `Credit(ctx, CreditInput)`: menulis ledger, membuat lot (dengan `expires_at` dan
+    `origin_lot_id` dari input), dan menambah saldo.
+  - `Debit(ctx, DebitInput)`: mengambil dari lot sesuai urutan K9 (atau dari lot
+    tertentu lebih dulu, untuk reversal di F10), menulis alokasi dan ledger, lalu

+    di-set di empat tempat: `OrderProcessorImpl.UpdateOrder`,
+    `OrderProcessorImpl.updateOrderStatus`, dan dua tempat di `split_bill_processor.go`.
+    Buat satu hook `onOrderPaid(orderID)` yang dipanggil dari keempatnya.
+  - Hook menjalankan earning **setelah** transaksi pembayaran commit, sehingga
+    kegagalan earning tidak menggagalkan pembayaran.
+  - Idempotency key `earn:{order_id}:{currency}`.
+  - Lewati order tanpa customer, customer default, atau customer nonaktif.
+  - **Jaring pengaman:** job yang mencari order lunas beberapa hari terakhir yang belum
+    punya `EARN` (dan seharusnya punya), lalu menjalankan ulang earning.
+- **Selesai jika:** test untuk pembayaran penuh, split bill (lunas di pembayaran
+  terakhir), self-order, dan pemanggilan ganda (hasilnya tetap satu earning). Earning
+  yang sengaja digagalkan tidak menggagalkan pembayaran dan terambil oleh job.
+- **Bergantung pada:** PC-104, PC-202
+
+### PC-204 · Reversal earning saat void / refund · M
+- **PRD:** F10, Q3
+- **Kerjakan:** panggil reversal dari `VoidOrder`, `RefundOrder`, dan `RefundPayment`.
+  Ambil pertama dari lot `EARN` order tersebut, lalu lot lain. Gunakan `DebitUpTo` dan
+  catat `shortfall`. Refund tidak pernah diblokir.
+- **Selesai jika:** test untuk void penuh, refund sebagian (proporsional, akumulasi tidak
+  melebihi earning), dan saldo yang sudah terpakai (shortfall tercatat, saldo 0).
+- **Bergantung pada:** PC-203
+
+### PC-205 · Tampilkan earning di order dan struk · S
+- **PRD:** F3
+- **Kerjakan:** tambah `points_earned` dan `coins_earned` ke response order dan data
+  struk.
+- **Selesai jika:** nilai sama dengan baris `EARN` di ledger, dan bernilai 0 untuk order
+  tanpa earning.

+> N3 (legal) ditutup.
+
+### PC-301 · PIN customer · L
+- **PRD:** K8, F11, Q16, Q17
+- **Kerjakan:**
+  - Migrasi kolom PIN di `customers` dan tabel `customer_security_events`.
+  - Purpose OTP baru `pin_setup` dan `pin_reset` di `OtpProcessor`.
+  - Endpoint `/customer/pin/*` (status, OTP, buat, ganti, reset).
+  - Hash bcrypt, tolak PIN lemah (digit sama, berurutan, tanggal lahir).
+  - Kunci 30 menit setelah 5 kali salah, dengan penghitung di database.
+  - Tahan transfer keluar 24 jam setelah reset.
+  - `VerifyPin(ctx, customerID, pin)` untuk dipakai task lain, dengan error
+    `PIN_NOT_SET`, `PIN_INVALID`, `PIN_LOCKED`, `TRANSFER_BLOCKED`.

+
+### PC-303 · Payment method EnakPoint · M
+- **PRD:** F9 (payment method), §8 (perubahan `payments`), §10.5
+- **Kerjakan:**
+  - Tambah tipe `point` ke `PaymentMethodType` dan validator (`oneof=cash card
+    digital_wallet point`).
+  - Migrasi kolom `points_used` dan `point_value` di `payments`.

+    otomatis untuk organisasi baru.
+  - Tolak hapus / ubah tipe method sistem.
+  - Sembunyikan method ini di kasir jika outlet tidak mengaktifkan `accept_payment`.
+- **Selesai jika:** setiap organisasi punya tepat satu method EnakPoint yang tidak bisa
+  dihapus.

+### PC-304 · Kode bayar sekali pakai · M
+- **PRD:** F9 (persetujuan customer), K8
+- **Kerjakan:** `POST /customer/wallet/payment-code` (butuh PIN) menghasilkan kode 6
+  digit dan QR yang berlaku 2 menit, disimpan di Redis dengan TTL dan diambil
+  sekali-pakai (`GETDEL`). Kode terikat ke `customer_id`.
+- **Selesai jika:** kode kedaluwarsa, kode yang sudah dipakai, dan kode milik customer
+  lain semuanya ditolak.
+- **Bergantung pada:** PC-301
+
+### PC-305 · Bayar EnakPoint di kasir · L
+- **PRD:** F9 (perhitungan, pencatatan), K7
+- **Kerjakan:**
+  - `GET /orders/:id/point-payment/preview`.
+  - Cabang method `point` di `CreatePayment`: validasi kode bayar, cocokkan customer
+    order, hitung `maks_point`, lalu lakukan langkah 1–6 F9 dalam **satu transaksi**
+    bersama pembuatan baris `payments`.
+  - Idempotency `payment:{payment_id}`.
+  - Tolak jika `nominal_rupiah > remaining_amount` (tidak ada kembalian).

+  `max_payment_percent`, order walk-in (ditolak), kode salah (ditolak), dan dua
+  pembayaran bersamaan untuk customer yang sama (saldo tidak terpakai dua kali).
+  Earning (PC-203) menghitung basis tanpa bagian EnakPoint.
+- **Bergantung pada:** PC-104, PC-303, PC-304
+
+### PC-306 · Bayar EnakPoint dari app / self-order · M
+- **PRD:** F9
+- **Kerjakan:** `POST /customer/orders/:id/pay-with-points` (butuh PIN, hanya untuk
+  order milik customer itu sendiri), memakai logika yang sama dengan PC-305.
+- **Selesai jika:** customer tidak bisa membayar order milik customer lain.
+- **Bergantung pada:** PC-305
+
+### PC-307 · Refund pembayaran EnakPoint · M
+- **PRD:** F9 (void/refund), K7, Q13
+- **Kerjakan:** `PAYMENT_REFUND` di jalur void dan refund memakai `point_value` yang
+  dibekukan, dengan pembulatan ke bawah. Kembalikan ke lot dengan `expires_at` asal
+  (aturan perpanjangan 7 hari mengikuti N4, jadi untuk sekarang cukup pakai tanggal
+  asal). **Tolak** permintaan refund bagian EnakPoint lewat method lain.
+- **Selesai jika:** test untuk void penuh, refund sebagian, perubahan nilai EnakPoint di
+  antara bayar dan refund (jumlah EnakPoint yang kembali tetap sama), dan percobaan
+  refund tunai atas pembayaran EnakPoint (ditolak).
+- **Bergantung pada:** PC-305
+
+### PC-308 · EnakPoint di laporan · S
+- **PRD:** F9 (laporan)
+- **Kerjakan:** laporan per payment method menampilkan EnakPoint terpisah dan tidak
+  menghitungnya sebagai kas masuk. Cek laporan analytics yang menjumlahkan pembayaran.
+- **Selesai jika:** total kas masuk di laporan tidak berubah saat sebagian order dibayar
+  EnakPoint. Perlakuan akuntansi lanjutan menunggu N2.
+- **Bergantung pada:** PC-305

+
+## Fase 4 — Pergerakan Saldo
+
+> Boleh dikerjakan sekarang. Transfer (PC-402) **tidak boleh dirilis** sebelum N3
+> (legal) ditutup.
+
+### PC-401 · Exchange EnakCoin → EnakPoint · M
+- **PRD:** F4, K3
+- **Kerjakan:** `GET /customer/wallet/exchange/preview` dan
+  `POST /customer/wallet/exchange` (butuh PIN, `Idempotency-Key`). Jumlah harus
+  kelipatan `coin_amount`. Kurs dibekukan di metadata. Lot EnakPoint kedaluwarsa pada
+  `min(lot EnakCoin asal, sekarang + masa berlaku EnakPoint)`.
+- **Selesai jika:** test untuk kurs default 1:1, kurs 10:3, jumlah bukan kelipatan
+  (ditolak), dan `expires_at` lot hasil exchange tidak pernah lebih lama dari lot asal.
+- **Bergantung pada:** PC-104, PC-301, PC-302
+
+### PC-402 · Transfer antar customer · L
+- **PRD:** F5, Q4, Q16
+- **Kerjakan:** `GET /customer/wallet/transfer/recipient` (nama disamarkan) dan
+  `POST /customer/wallet/transfer` (butuh PIN, `Idempotency-Key`). Kunci dua wallet
+  berurutan, cek batas organisasi (per transaksi dan harian), cek
+  `transfer_blocked_until`. Lot penerima mewarisi `expires_at` dan `origin_lot_id` dari
+  lot pengirim. Kirim notifikasi push ke penerima.
+- **Selesai jika:** test untuk transfer ke diri sendiri / customer lain organisasi /
+  customer default (semua ditolak), batas harian, transfer dua arah bersamaan (tidak
+  deadlock), dan `expires_at` di penerima sama persis dengan pengirim.
+- **Bergantung pada:** PC-104, PC-301, PC-302
+
+### PC-403 · Semua game memakai EnakCoin · M
+- **PRD:** F8, K1
+- **Kerjakan:**
+  - `GamePlayProcessor.PlayGame` memotong EnakCoin lewat wallet engine sesuai
+    `games.metadata.coin_cost`.
+  - Seluruh permainan dalam satu transaksi: ubah repository game, game play, dan game
+    prize ke `DBFromContext`. Gagal mengurangi stok hadiah membatalkan permainan (saat
+    ini hanya di-`Printf`), dan rollback manual `AddTokens` dihapus.
+  - Rename `game_plays.token_used` menjadi `coins_used`.
+- **Selesai jika:** test untuk saldo kurang (ditolak, tidak ada `game_plays` yang
+  tercatat), stok hadiah gagal (semua dibatalkan), dan `GAME_SPEND` menunjuk
+  `game_plays.id`.
+- **Bergantung pada:** PC-104
+
+### PC-404 · Telusuri per butir di dashboard · S
+- **PRD:** F7, §8.1 (per butir)
+- **Kerjakan:** `GET /marketing/wallet-transactions/:id/trace` yang mengembalikan
+  alokasi lot dan rantai `origin_lot_id` sampai ke lot pertama.
+- **Selesai jika:** contoh di §8 (A transfer 120 ke B, B bayar 30) menelusuri ke order
+  #ORD-1 milik A.
+- **Bergantung pada:** PC-402
+
+---
+
+## Fase 5 — Kedaluwarsa
+
+> **Jangan dikerjakan sebelum catatan N4 (model kedaluwarsa) diputuskan.** Struktur lot
+> sudah ada sejak PC-101, jadi yang tersisa hanya rumus, job, dan tampilan.
+
+### PC-501 · Setting kedaluwarsa · M
+- **PRD:** F12 (pengaturan), N4
+- **Kerjakan:** key setting sesuai model yang dipilih di N4, dengan validasi dan preview
+  "saldo yang didapat hari ini kedaluwarsa pada …".
+- **Bergantung pada:** PC-302, **N4**
+
+### PC-502 · Hitung `expires_at` saat lot dibuat · M
+- **PRD:** F12 (tabel kedaluwarsa per lot), N4
+- **Kerjakan:** satu fungsi `ComputeExpiry(currency, receivedAt, settings)` yang dipakai
+  oleh `EARN` dan `ADJUSTMENT`, serta aturan aktivasi pertama untuk lot lama (termasuk
+  lot `MIGRATION`).
+- **Bergantung pada:** PC-104, PC-501
+
+### PC-503 · Job kedaluwarsa · M
+- **PRD:** F12 (proses kedaluwarsa)
+- **Kerjakan:** job per jam yang memproses lot lewat tanggal dengan `EXPIRE`
+  (idempotency `expire:{lot_id}`) di bawah lock wallet.
+  - **Jangan menyalin pola `OmsetMilestoneScheduler`.** Scheduler itu menyimpan state di
+    memori, dan menurut komentarnya sendiri bisa mengirim ulang notifikasi setelah
+    restart. Job ini harus aman dijalankan di banyak instance sekaligus: pilih lot
+    dengan `FOR UPDATE SKIP LOCKED`, dan andalkan idempotency key.
+- **Selesai jika:** dua instance yang berjalan bersamaan tidak menghanguskan lot yang
+  sama dua kali, dan tidak ada lot yang lewat tanggal lebih dari 1 jam tanpa diproses.
+- **Bergantung pada:** PC-502
+
+### PC-504 · Pengingat dan tampilan saldo yang akan kedaluwarsa · M
+- **PRD:** F6 (`/wallet/expiring`), F12 (pengingat)
+- **Kerjakan:** endpoint `GET /customer/wallet/expiring`, field saldo kedaluwarsa
+  terdekat di `/wallet`, dan notifikasi pengingat yang dikelompokkan per tanggal.
+  Jadwal pengingat mengikuti N4.
+- **Bergantung pada:** PC-503
+
+---
+
+## Fase 6 — Bersih-bersih
+
+### PC-601 · Hapus tabel dan kode lama · S
+- **PRD:** §10.7
+- **Kerjakan:** satu rilis setelah PC-105 berjalan di production, drop
+  `customer_points` dan `customer_tokens`. Hapus `CustomerPointsProcessor` dan
+  `CustomerTokensProcessor` beserta stub `not implemented`, rute yang di-comment di
+  `router.go`, dan alias `/customer/points` / `/customer/tokens` setelah aplikasi
+  diperbarui.
+- **Bergantung pada:** PC-106, PC-403, dan konfirmasi bahwa aplikasi sudah tidak
+  memanggil endpoint lama.
+
+### PC-602 · Dokumentasi integrasi · S
+- **Kerjakan:** panduan integrasi untuk tim aplikasi dan POS (seperti
+  `integration-weight-based-products.md`): endpoint, kode error PIN, alur kode bayar, dan
+  contoh request/response.
+- **Bergantung pada:** PC-305, PC-402
+
+---
+
+## Yang Bisa Dimulai Sekarang
+
+Bisa dikerjakan paralel tanpa menunggu apa pun:
+- **PC-101** (migrasi wallet) → langsung lanjut **PC-103**, lalu **PC-104**
+- **PC-102** (setting organisasi) → **PC-109**
+- **PC-301** (PIN customer)
+- **PC-303** (payment method EnakPoint)
+
+PC-104 adalah jalur kritis: hampir semua task lain menunggunya.
