 ### Prasyarat

- Flutter SDK `^3.8.1`
- Dart SDK `^3.8.1`
+- **FVM** — project ini mengunci versi Flutter, jangan pakai Flutter global
+- **Flutter 3.41.9** (Dart 3.11.5) — dipin di `.fvmrc`
 - Android SDK / Xcode (untuk iOS)
 - Firebase project yang sudah dikonfigurasi

+> **Kenapa versinya dikunci?** Stack code generation project ini (`freezed` 2.x, `build_runner` 2.5, `analyzer` 7.7.1) hanya paham bahasa Dart sampai 3.9. Flutter 3.44 ke atas membawa framework yang ditulis di bahasa 3.10+, dan `analyzer` 7.7.1 crash saat membacanya. Selama stack codegen belum dinaikkan, **Flutter 3.41.9 adalah versi terbaru yang masih bisa menjalankan `build_runner`.** Lihat [Troubleshooting](#troubleshooting).
+
 ### Instalasi

 ```bash
@@ -90,44 +93,120 @@ feature/

 cd apskel-pos-flutter-v2

-# Install dependencies
-flutter pub get
+# Pasang FVM (sekali per mesin)

+# Ambil & pakai versi Flutter yang dipin di .fvmrc
+fvm install
+fvm use
 ```

+`dart pub global activate` memasang `fvm` ke folder bin milik pub yang **belum tentu ada di PATH**. Kalau muncul `fvm: command not found` / `The term 'fvm' is not recognized`, tambahkan foldernya sekali saja:
+
+```powershell
+# Windows PowerShell — permanen, buka terminal baru setelahnya
+[Environment]::SetEnvironmentVariable('Path', [Environment]::GetEnvironmentVariable('Path','User') + ";$env:LOCALAPPDATA\Pub\Cache\bin", 'User')

+```
+
+```bash
+# macOS / Linux — tambahkan ke ~/.zshrc atau ~/.bashrc

+Setelah `fvm` bisa dipanggil, lanjutkan:
+
+```bash
+# Install dependencies
+fvm flutter pub get
+
+# Generate kode
+fvm dart run build_runner build
+```
+
+> Semua perintah Flutter/Dart di project ini **harus diawali `fvm`**. `flutter run` tanpa `fvm` memakai Flutter global dan hasilnya bisa berbeda.
+
 ### Menjalankan App

+Environment **tidak** ditentukan otomatis dari debug/release — harus dioper lewat `--dart-define`:
+
 ```bash
 # Development
-flutter run
+fvm flutter run --dart-define=ENV=dev

-# Release
-flutter run --release
+# Production
+fvm flutter run --dart-define=ENV=prod
+
+# Production, release mode
+fvm flutter run --release --dart-define=ENV=prod
 ```

-App otomatis menggunakan environment `dev` saat debug dan `prod` saat release.
+Kalau `ENV` tidak dioper, nilainya jatuh ke `dev` (lihat `defaultValue` di `lib/main.dart`).
+
+Di VSCode sudah tersedia konfigurasi **Dev** dan **Prod** di `.vscode/launch.json`, tinggal pilih di panel Run and Debug.
+
+### Build
+
+`--dart-define=ENV=prod` wajib ikut, kalau tidak APK-nya akan memakai database dan base URL milik dev:
+
+```bash
+# APK
+fvm flutter build apk --release --dart-define=ENV=prod
+
+fvm flutter build apk --release --split-per-abi --dart-define=ENV=prod
+
+# App Bundle (Play Store)
+fvm flutter build appbundle --release --dart-define=ENV=prod
+
+# iOS
+fvm flutter build ipa --release --dart-define=ENV=prod
+```
+
+---
+
+## Code Generation
+
+Project ini banyak memakai kode generated (`freezed`, `injectable`, `auto_route`, `json_serializable`, `flutter_gen`). Kode itu **wajib di-generate ulang** setiap kali kamu:
+
+- menambah/mengubah kelas `@freezed` (entity, event, state, DTO)
+- menambah/mengubah anotasi DI (`@injectable`, `@LazySingleton`, `@Injectable(as: ...)`)
+- menambah halaman baru dengan `@RoutePage()`
+- menambah aset di `pubspec.yaml`
+
+```bash
+# Sekali jalan
+fvm dart run build_runner build
+
+# Mode watch — regenerate otomatis saat file berubah, enak dipakai saat ngoding
+fvm dart run build_runner watch
+```
+
+> **Hindari `--delete-conflicting-outputs`.** Flag itu menghapus seluruh file generated **sebelum** mulai build. Kalau build-nya gagal di tengah jalan, kamu berakhir tanpa kode generated sama sekali dan project tidak bisa di-compile. Pakai hanya kalau build_runner benar-benar mengeluh soal konflik output, dan pastikan working tree-mu bersih dulu supaya bisa `git restore`.

 ## Environment

+Konfigurasi environment ada di `lib/env.dart` — **itu sumber kebenarannya**, jangan disalin ke sini karena gampang basi.

-| Environment | Base URL | Database |
-|---|---|---|
-| `dev` | `https://api-pos.apskel.id` | `apskel_pos_dev.db` |
-| `prod` | `https://api-pos.apskel.id` | `apskel_pos_dev.db` |

+| ----------- | ----------------------- |

+| `prod`      | `apskel_pos_prod.db`    |

-Environment dipilih otomatis di `main.dart`:
+Environment dipilih dari `--dart-define=ENV=...` di `lib/main.dart`:

 ```dart
-await configureDependencies(
-  kReleaseMode ? Environment.prod : Environment.dev,
-);
+const String env = String.fromEnvironment('ENV', defaultValue: 'dev');
+await configureDependencies(env);
 ```

+Nilai `env` diteruskan ke `injectable`, yang lalu memilih antara `DevEnv` (`@dev`) dan `ProdEnv` (`@prod`). Menambah environment baru berarti menambah kelas ber-anotasi di `lib/env.dart`, lalu generate ulang.
+
+Karena `dev` dan `prod` memakai **nama database berbeda**, berpindah environment di perangkat yang sama tidak akan mencampur datanya.

 ## Catatan Development

+- Selalu pakai `fvm flutter` / `fvm dart`, bukan `flutter` / `dart` global
 - Jangan edit `injection.config.dart` dan file `*.freezed.dart` / `*.g.dart` secara manual — file tersebut di-generate otomatis
+- Setelah mengubah kelas `@freezed` atau anotasi DI, jalankan build_runner sebelum menjalankan app
 - Gunakan `log()` dari `dart:developer` untuk logging, bukan `print()`
 - `print()` dinonaktifkan di release mode
+

+
+## Troubleshooting
+
+### `build_runner` gagal: `Missing implementation of visitDotShorthandPropertyAccess`
+
+Kamu sedang memakai Flutter yang terlalu baru. Cek:
+
+```bash
+fvm flutter --version   # harus 3.41.9
+flutter --version       # ini Flutter global, boleh versi apa saja
+```
+
+Kalau versinya bukan 3.41.9, artinya perintahnya jalan tanpa `fvm`. Log build juga memberi petunjuk yang sama:
+
+```
+SDK language version 3.13.0 is newer than `analyzer` language version 3.9.0
+```
+
+Perbaikannya: `fvm use`, lalu ulangi dengan awalan `fvm`.
+
+Menaikkan Flutter melewati 3.41.x mengharuskan seluruh stack codegen ikut naik — `freezed` 2 → 3/4, `build_runner` → 2.16, `injectable_generator` 2 → 3, `auto_route` 9 → 10. `freezed` 3 mewajibkan tiap kelas dideklarasikan `abstract`/`sealed` dan menghapus `when`/`map` (diganti pattern matching), jadi ini pekerjaan tersendiri, bukan sambilan.
+
+### Project tidak bisa di-compile, banyak error `_$Something` tidak ditemukan
+
+Kode generated-nya hilang atau belum dibuat. Jalankan:
+
+```bash
+fvm dart run build_runner build
+```
+
+### `fvm: command not found`
+
+FVM terpasang di `~/AppData/Local/Pub/Cache/bin` (Windows) atau `~/.pub-cache/bin` (macOS/Linux) yang mungkin belum ada di `PATH`. Tambahkan direktori itu ke `PATH`, atau panggil dengan path lengkap.

+# Integrasi Produk Timbangan — POS Mobile & Backoffice
+
+**Migrasi:** `000089` · **Base URL:** `/api/v1` · **Kompatibilitas:** mundur penuh
+
+Panduan untuk menjual produk per timbangan (ikan, daging, buah) dari sisi klien.
+Alasan di balik setiap keputusan desain ada di [`rfc-weight-based-products.md`](./rfc-weight-based-products.md).
+
+---
+
+## 1. Konsep inti
+
+**Satu penimbangan = satu baris order.**
+
+Pelanggan memesan Ikan Tude 4,2 ons, lalu memesan Ikan Tude lagi 5,6 ons. Itu **dua
+baris terpisah**, karena keduanya dua ikan berbeda yang ditimbang sendiri-sendiri.
+
+| Bukan begini | Melainkan begini |
+|---|---|
+| `quantity: 9.8` | `quantity: 1, weight: 4.2`<br>`quantity: 1, weight: 5.6` |
+| Dua ikan hilang jejaknya, dan `quantity` bertipe integer sehingga pecahan ditolak | Tiap penimbangan berdiri sendiri, bisa di-void atau dibayar terpisah |
+
+Empat aturan yang berlaku di seluruh dokumen ini:
+
+1. `quantity` untuk produk timbangan **selalu 1**. Backend memaksanya, dan database
+   menolak nilai lain lewat constraint `chk_order_items_weight_single_line`.
+2. `weight` menyimpan angka timbangan, dalam satuan produk itu sendiri (ons, kg, gram —
+   apa pun yang dipilih saat setup).
+3. Harga baris dihitung `weight × unit_price`, bukan `quantity × unit_price`.
+   `unit_price` tetap berarti harga per satu satuan (per ons).
+4. **Jangan pernah menggabungkan dua baris** produk timbangan menjadi satu, meski
+   produknya sama.
+
+Untuk produk biasa tidak ada yang berubah: `weight` tidak dikirim, `quantity` tetap
+cacah seperti sekarang.
+
+---
+
+## 2. Backoffice — setup produk
+
+### 2.1 Pastikan satuannya ada
+
+Satuan disimpan per organisasi. Buat sekali, pakai ulang untuk semua produk timbangan.
+
+`POST /api/v1/units`
+
+```json
+{
+  "name": "Ons",
+  "abbreviation": "ons",
+  "is_active": true
+}
+```
+
+`abbreviation` yang dipakai POS untuk mencetak `4,2 ons` di struk — isi dengan bentuk
+pendek yang benar-benar ingin ditampilkan. Daftar satuan dibaca lewat `GET /api/v1/units`.
+
+### 2.2 Buat produk sebagai produk timbangan
+
+`POST /api/v1/products`
+
+```json
+{
+  "category_id": "…",
+  "name": "Ikan Tude",
+  "price": 4500,
+  "cost": 3000,
+  "sell_by": "weight",
+  "unit_id": "<id satuan Ons>"
+}
+```
+
+| Field | Tipe | Keterangan |
+|---|---|---|
+| `sell_by` | `"unit"` \| `"weight"` | Opsional, default `"unit"`. Nilai lain **ditolak** dengan pesan jelas. |
+| `unit_id` | UUID | **Wajib** saat `sell_by: "weight"`, ditolak backend bila kosong. Opsional untuk produk satuan. |
+| `price` | number | Harga per satu satuan. Rp 4.500 per ons, bukan harga per ikan. |
+
+Pada `PUT /api/v1/products/:id`, `unit_id` **tidak perlu dikirim ulang** bila produknya
+sudah punya satuan — mengubah `sell_by` menjadi `"weight"` saja sudah cukup. Yang ditolak
+adalah kondisi akhirnya: produk yang dijual per timbangan tanpa satuan.
+
+Keduanya juga bisa diubah lewat `PUT /api/v1/products/:id` dengan bentuk yang sama, dan
+ikut terbaca di setiap response produk (`GET /api/v1/products`, `/products/all`,
+`/products/:id`).
+
+### 2.3 Catatan UI
+
+- Kunci `sell_by` **setelah produk punya transaksi**. Mengubah produk lama dari `unit`
+  ke `weight` tidak mengubah baris order yang sudah ada — baris lama tetap dihitung per
+  cacah — tapi akan membingungkan pengguna yang melihat riwayatnya.
+- Saat `weight` dipilih, jadikan pemilih satuan sebagai field **wajib** di form. Backend
+  juga menolaknya, tapi ditangkap di form lebih baik daripada baru gagal saat simpan.
+- Ubah label harga mengikuti satuan yang dipilih: *"Harga per ons"*.
+- Untuk produk satuan, pemilih satuan boleh disembunyikan — `unit_id` opsional dan belum
+  dikonsumsi apa pun di POS.
+
+---
+
+## 3. POS Mobile — transaksi
+
+### 3.1 Bentuk input mengikuti `sell_by`
+
+| `sell_by` | Input di POS | Yang dikirim |
+|---|---|---|
+| `"unit"` | Stepper − / + seperti sekarang | `quantity: n`, tanpa `weight` |
+| `"weight"` | Papan angka desimal, satuan dari `unit` produk | `quantity: 1` + `weight: 4.2` |
+
+### 3.2 Mengirim order
+
+`POST /api/v1/orders`
+
+```json
+{
+  "outlet_id": "…",
+  "user_id": "…",
+  "order_type": "dine_in",
+  "order_items": [
+    { "product_id": "<ikan-tude>",  "quantity": 1, "weight": 4.2 },
+    { "product_id": "<ikan-tude>",  "quantity": 1, "weight": 5.6 },
+    { "product_id": "<nasi-goreng>", "quantity": 2 }
+  ]
+}
+```
+
+Bentuk yang sama berlaku untuk `POST /api/v1/orders/:id/add-items` dan untuk pemesanan
+mandiri `POST /api/v1/self-order/orders`.
+
+**Presisi.** Berat dibulatkan backend ke 3 desimal. Kirim `4.2` atau `4.237`; angka di
+bawah `0.001` membulat ke nol dan ditolak.
+
+**Harga.** Field `unit_price` pada request **diabaikan** — harga selalu diambil backend
+dari master produk. Jangan mengirim harga hasil hitungan sendiri.
+
+---
+
+## 4. Menampilkan baris
+
+Setiap `order_items[]` di response membawa empat field tambahan:
+
+```json
+{
+  "product_name": "Ikan Tude",
+  "quantity": 1,
+  "weight": 4.2,
+  "unit_id": "…",
+  "unit_name": "Ons",
+  "unit_abbreviation": "ons",
+  "unit_price": 4500,
+  "total_price": 18900
+}
+```
+
+Semuanya `null` atau absen untuk produk biasa, jadi cabangkan tampilan pada `weight`:
+
+| Kondisi | Tampilkan |
+|---|---|
+| `weight == null` | `2 × Rp 25.000` |
+| `weight != null` | `4,2 ons × Rp 4.500` |
+
+**Jangan menampilkan `quantity` untuk baris berbobot** — nilainya selalu 1 dan akan
+terbaca seperti "satu ons". Gunakan `weight` dengan `unit_abbreviation`, dan pakai koma
+desimal sesuai format Indonesia.
+
+---
+
+## 5. Void, refund, split bill
+
+Baris berbobot bersifat **utuh**: dibatalkan seluruhnya atau tidak sama sekali. Karena
+`quantity`-nya 1, semua endpoint cukup dikirimi `1`, dan backend menghitung nilai
+rupiahnya dari `weight`.
+
+| Aksi | Endpoint | Field untuk baris berbobot |
+|---|---|---|
+| Void per item | `POST /orders/void` | `items[].quantity: 1` |
+| Refund per item | `POST /orders/:id/refund` | `order_items[].refund_quantity: 1` (atau kosongkan) |
+| Split bill per item | `POST /orders/split-bill` | `items[].quantity: 1` = bayar baris itu penuh |
+
+```json
+{
+  "order_id": "…",
+  "reason": "Salah timbang",
+  "type": "ITEM",
+  "items": [
+    { "order_item_id": "<baris 4,2 ons>", "quantity": 1 }
+  ]
+}
+```
+
+Untuk split bill, baris berbobot hanya bisa berstatus belum dibayar atau lunas — tidak
+ada nilai di antaranya. Sembunyikan stepper jumlah pada baris berbobot, ganti dengan
+tombol pilih baris.
+
+**Batasan yang disengaja.** Mengembalikan *sebagian berat* — 1 ons dari baris 4,2 ons —
+tidak didukung. Koreksi salah timbang ditangani dengan void baris itu lalu input ulang,
+sehingga jejak auditnya tetap jujur.
+
+---
+
+## 6. Referensi error
+
+Semua error mengikuti amplop standar. Pesan validasi baru muncul dengan kode `900`:
+
+```json
+{
+  "success": false,
+  "data": null,
+  "errors": [
+    { "code": "900", "entity": "ORDER",
+      "cause": "product Ikan Tude is sold by weight and requires a weight" }
+  ]
+}
+```
+
+| Pesan (`cause`) | Penyebab | Perbaikan di klien |
+|---|---|---|
+| `… is sold by weight and requires a weight` | Produk `sell_by: "weight"` dikirim tanpa `weight` | Wajibkan input timbangan sebelum item masuk keranjang |
+| `… is not sold by weight and must not carry a weight` | `weight` dikirim untuk produk satuan | Kirim `weight` hanya bila `sell_by == "weight"` |
+| `weight for … must be greater than 0` | Berat nol, negatif, atau membulat ke nol | Validasi minimal `0.001` di keypad |
+| `quantity for … must be at least 1` | Produk satuan dengan `quantity` ≤ 0 | Perilaku lama, tidak berubah |
+
+Pesan menyebut **nama produk**, sehingga bisa ditampilkan apa adanya ke kasir.
+
+### Setup produk (Backoffice)
+
+| Pesan (`cause`) | Penyebab | Perbaikan di klien |
+|---|---|---|
+| `unit_id is required when sell_by is 'weight'` | Produk timbangan dibuat tanpa satuan | Wajibkan pemilih satuan saat Timbangan dipilih |
+| `sell_by must be either 'unit' or 'weight'` | Nilai `sell_by` di luar dua itu | Kirim persis `"unit"` atau `"weight"` |
+| `product '…' is sold by weight and requires a unit_id` | Update membuat produk jadi timbangan tanpa satuan | Kirim `unit_id` bersama perubahan `sell_by` |
+
+---
+
+## 7. Kompatibilitas mundur
+
+- Semua produk lama otomatis `sell_by: "unit"`. Perilakunya identik dengan sebelumnya.
+- `weight` opsional di request. Klien yang tidak mengenalnya tetap berfungsi penuh untuk
+  produk satuan.
+- Field baru di response semuanya `omitempty` — tidak muncul untuk baris biasa, jadi
+  parser lama tidak terganggu.
+- `quantity` tetap **integer** di seluruh API. Tidak ada field yang berubah tipe.
+
+Yang tidak berfungsi di klien lama hanyalah menjual produk timbangan itu sendiri —
+permintaannya ditolak dengan pesan jelas, bukan gagal diam-diam.
+
+---
+
+## 8. Batasan yang diketahui
+
+- **Pembulatan uang ke 2 desimal.** `4,237 ons × Rp 4.500` tersimpan `Rp 19.066,50`,
+  bukan dibulatkan ke rupiah utuh. Bila kasir harus menerima rupiah penuh, ini perlu
+  diputuskan dan diubah di backend lebih dulu (`RoundMoney`, satu tempat).
+- **Stok belum otomatis berkurang** saat penjualan — untuk produk timbangan maupun
+  produk biasa. Pengurangan stok belum tersambung di backend, jadi jangan menampilkan
+  sisa stok yang mengandaikan itu berjalan.
+
+---
+
+## 9. Checklist per tim

efrilmandClaude Opus 5	7986164a17	fix: beri tiap tab pengaturan printer bloc sendiri PrinterFormBloc dan PrinterLoaderBloc di-provide sekali secara global, sementara lima tab pengaturan printer hidup bersamaan di dalam TabBarView dan semuanya membaca-menulis state yang sama. Karena created dan updated membangun entitas Printer sepenuhnya dari state itu (type, address, code, name, paper), tab yang terakhir menulis state akan menang, lalu tombol Simpan di tab mana pun menyimpan milik tab lain. Nilai awal state kebetulan type 'Bluetooth' — itu sebabnya printer kitchen tersimpan dengan alamat IP yang benar tapi tipe Bluetooth, dan cetakannya dikirim ke radio Bluetooth untuk mencari perangkat yang tidak pernah ada. Provider global dihapus karena tidak ada tempat lain yang memakainya. Catatan: ini mencegah kerusakan baru, tidak memulihkan baris yang sudah terlanjur salah di SQLite — konfigurasi kelima tab perlu disimpan ulang. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-09-05 14:06:34 +07:00
efrilmandClaude Opus 5	32f64a197a	fix: pulihkan koneksi Bluetooth dan deteksi kegagalan printer jaringan Bluetooth: percobaan ulang connect sebelumnya tidak menutup socket lebih dulu, padahal 'read failed, socket might closed or timeout' justru berarti socket RFCOMM masih setengah terbuka — ketiga percobaan gagal identik dan retry-nya sia-sia. Tiap percobaan ulang kini didahului disconnect paksa. connectBluetooth mengembalikan sukses begitu ADA koneksi tanpa memeriksa apakah itu printer yang diminta, dan tidak pernah mencatat MAC yang aktif. Kini memakai jalur yang sama dengan mencetak. Izin runtime Bluetooth sebelumnya hanya diminta dari dialog pilih perangkat. Karena reinstall mencabut izin, kasir yang tidak pernah membuka dialog itu gagal cetak tanpa penjelasan. Status adapter, izin, dan pairing kini ikut di log, dan printer yang tidak ter-pairing digagalkan langsung dengan pesan yang menyebut tindakannya. Jaringan: printTicket hanya menaruh byte di socket lalu menutup koneksi, tidak pernah membaca balik, sehingga kertas habis atau cover terbuka terlihat sama dengan sukses — itu sebabnya kegagalan kitchen tidak pernah muncul di Crashlytics. NetworkPrinterClient baru menanyakan kondisi printer lewat DLE EOT sebelum dan sesudah mencetak, dengan degradasi anggun untuk printer yang tidak mendukungnya. Panggilan disconnect() ganda dihapus; printTicket sudah flush dan close sendiri, dan panggilan kedua tanpa await membuat error-nya tercatat sebagai crash fatal palsu. Ditambah jejak per station ke Crashlytics. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-09-05 14:06:22 +07:00

efrilmandClaude Opus 5	ebcddca4bb	docs: perbarui README untuk FVM, build_runner, dan cara run/build Bagian setup lama tidak cuma kurang, tapi salah: diklaim environment dipilih otomatis dari debug/release, padahal datang dari --dart-define=ENV. Siapa pun yang mengikutinya akan menghasilkan APK 'production' yang menunjuk database dev. Tabel environment dan contoh kodenya juga sudah tidak sesuai isi lib/env.dart. Ditambah: prasyarat FVM, langkah instalasi ber-fvm, perintah build per environment, bagian Code Generation (termasuk peringatan --delete-conflicting-outputs yang menghapus seluruh file generated sebelum build), dan Troubleshooting. URL base sengaja tidak disalin ke README; cukup menunjuk lib/env.dart, karena menyalin nilai itulah yang membuat dokumen ini basi.

efrilmandClaude Opus 5	1b4caf45d5	fix: cetak semua station tanpa saling membatalkan printStruckOrder berhenti di kegagalan pertama, jadi satu station gagal membuat semua station sesudahnya tidak pernah dicoba. Karena checker (Bluetooth) berada sebelum kitchen dan bar (Network) dalam rantai, satu kegagalan koneksi Bluetooth menghilangkan tiga tiket sekaligus, dua di antaranya di jaringan yang sehat. Jalur printer Network juga mengembalikan right(false) saat gagal, yang lolos sebagai sukses ke pemanggil, sehingga kasir melihat 'berhasil dicetak' padahal tidak ada kertas keluar. Perubahan: repository kini mengembalikan Stream<List<PrintStationResult>> dan tetap mencoba semua station; kegagalan Network jadi left; station Network berjalan paralel dengan rantai Bluetooth; station Bluetooth dikelompokkan per alamat agar perpindahan koneksi seminimal mungkin; CapabilityProfile di-cache. Bluetooth: retry connect dengan backoff dan disconnect di tiap percobaan ulang (socket RFCOMM setengah terbuka membuat connect berulang gagal identik), jeda settle dikembalikan setelah dipangkas ke 300ms, satu lock untuk seluruh radio (bukan per MAC), izin runtime dipastikan di jalur cetak, dan repository jadi LazySingleton agar state koneksi benar-benar dibagi. UI: dialog progres per-station menggantikan toast tunggal, lengkap dengan durasi tiap station dan tombol cetak ulang khusus yang gagal. Enam listener duplikat di halaman diganti satu listener terpusat di AppWidget. Menu Print di detail transaksi dapat item Print All.
