 ## Changelog
 
+### v1.3.0+7 — 2026-10-18
+  - **Offline sync indikator status:** badge `Menunggu sinkron` di daftar Riwayat + baris `Sinkronisasi: Belum terkirim ke server` di detail transaksi. `AppState.pendingSaleIds`, `isSalePending()`, `pendingOfflineCount`.
+  - **Retry antrean otomatis:** `retryNow()` dipanggil dari `init()`, event connectivity, dan `addToQueue()` setelah proses antrean; verifikasi server reachable (ping 5 detik) sebelum sinkron.
+  - **Release APK:** `app-release.apk` (68.1MB), tag `v1.3.0+7`, di-upload ke Gitea Release.
+
+### v1.3.0+6 — 2026-10-18
+- **Kasir list + toggle grid/list:** default list (foto 56px), toggle ke grid. Tap = tambah qty berkali-kali. Highlight hijau sesaat (0.9s). Tombol keranjang + badge jumlah item.
+- **Notifikasi in-app:** banner SnackBar + getar — hanya untuk admin, hanya untuk transaksi dari orang lain (bukan transaksi admin sendiri). Deteksi via polling (interval 1 menit) + stream `newSaleNotifications`. Load pertama dilewati agar tidak spam.
+- **Badge Riwayat:** `unseenSalesCount` di tab Riwayat (admin only), reset saat tab dibuka (`markSalesSeen()`).
+- **Fix tombol "Muat lebih banyak" Riwayat:** cek `filteredSales.length` bukan `state.sales` (sebelumnya negatif -17 saat filter aktif).
+- **Produk hilang / loading terus di layar Kasir (fix 3 lapis):**
+  1. `_loadProducts()` now non-crashing saat Supabase return 401; empty server result does **not** overwrite in-memory `products` (previously `products = []` wiped the on-screen list).
+  2. `_init()` no longer waits `& _initAuth()` first. Auth check now via `_ensureSessionAndAuth()`: if refresh token expired, immediately set `_sessionExpired = true`, keep `startPolling()` alive, and show a "login ulang" message. This avoids `_loadProducts()` being blocked by a 30s timeout + 401.
+  3. `_refresh()` and realtime `.stream()` products stay alive via 1-minute polling (30 default products, "Muat lebih banyak" to extend).
+- **Auth flow lengkap (2026-10-18):** `login_screen.dart` + `AuthGate` (main.dart) sudah ada & ter-wiring. Dilengkapi: `AuthGate` sekarang route ke `LoginScreen` saat `state.sessionExpired` true (bukan cuma `!isLoggedIn`) — saat session mati user dipaksa login ulang, bukan nyangkut di HomePage dengan sesi mati. `_ensureSessionAndAuth()` membedakan auth benar-benar mati (`AuthException`/refresh balikin session tak valid → `sessionExpired=true`) vs network blip (error jaringan → TIDAK tandai sessionExpired, jadi tak salah-logout saat internet putus sesaat). `refresh()` stop query saat auth mati (hindari 401 sia-sia + cukup notify agar redirect). `login()` reset `sessionExpired` + langsung muat produk/riwayat (tak tunggu poll 1 menit).
+- **Kasir: indikator loading produk + empty/error state (2026-10-18):** setelah login user sempat melihat daftar kosong lalu produk muncul beberapa saat kemudian. Sebab otentik: `AuthGate → HomePage` render duluan, `refresh() → _loadProducts()` jalan belakangan tanpa indikator. Perbaikan kini: `AppState.productsLoading/dataReady/productsError` + `retryProducts()`; Kasir menampilkan skeleton daftar `_ProductsLoading` khusus saat muat awal, banner `Gagal memuat produk` + tombol `Coba lagi` saat error, dan empty-state `Belum ada produk`/`Tidak ditemukan` sesuai kasus. `refresh()` diberi retry 1x + try-catch internal sehingga `_loadSales()` tidak men-stop loop; LoginScreen tetap dipakai (tanpa loading global) agar pesan error/login tidak hilang.
+- **Offline queue: transaksi offline kini disinkron ulang otomatis (2026-10-18):** laporan user — transaksi saat data mati tidak masuk walau data sudah nyala. Sebab: sync antrean hanya dipicu event `connectivity_plus` (radio nyala ≠ server reachable) dan polling tidak menyentuh antrean. Perbaikan: `OfflineQueueService.retryNow()` (re-check koneksi + ping ringan Supabase 5 dtk sebelum proses antrean) dipanggil setiap `refresh()` sukses; log `OfflineQueue gagal sinkron item <id>: <error>`; tambah izin Android `INTERNET` + `ACCESS_NETWORK_STATE` (sebelumnya tidak ada di manifest, deteksi konektivitas tidak andal).
+  - **Indikator status sinkron di Riwayat (2026-10-18):** transaksi yang masih dalam antrean offline ditandai badge `Menunggu sinkron` (ikon jam pasir) di daftar Riwayat + baris `Sinkronisasi: Belum terkirim ke server` di detail transaksi. `AppState.pendingSaleIds`, `isSalePending()`, `pendingOfflineCount` dipakai UI untuk menandai status.
+- Fix Gitea ROOT_URL (infra): link download APK sebelumnya mengarah ke IP Tailscale lama → fixed ke `https://git.gosambi.uk/`.
+
+### v1.2.0+5 — 2026-10-17
+- **Foto produk:** bucket Supabase Storage `product-images` (publik, limit 5MB, jpg/png/webp) + kolom `products.image_path`. `image_picker` ^1.2.0 (kompres 800px/quality80). Tombol Kamera/Galeri/Hapus di form Tambah+Edit (`produk_screen.dart`). Thumbnail di daftar produk (`_ProductRow`) + keranjang kasir (`_KasirAvatar`). AndroidManifest +queries intent kamera/galeri.
+- **Fix MIME:** `image/jpg` → `image/jpeg` (server 415).
+- **Fix storage policy:** bucket `storage.objects` tanpa policy → upload 403. Fix: 3 policy SQL (INSERT auth, SELECT public, DELETE auth) — fix di server, APK tidak perlu rebuild.
+
 ### v1.1.0 — 2026-07-24
 - Dialog pembayaran kasir: tombol "Selesai & Cetak" menampilkan loading state (spinner + "Memproses...") dengan guard anti-doble-klik.
 - Dialog struk pembayaran: tombol "Cetak Struk" memiliki loading state ("Mencetak...") dan disable saat proses cetak.

+## Infra & Setup App
+
+### Backend Supabase (Self-Host)
+- URL: `https://supa.gosambi.uk` (gateway envoy port 8001)
+- Keys: `D:\HomeLabs\backups\supabase-keys-local.txt` (ANON + SERVICE)
+- Backup data: script `D:\HomeLabs\scripts\supabase_backup.py` → `D:\HomeLabs\backups\supabase-nwuupvnodsgxdhqcakqr\`
+- Schema backup: `backups\...\schema_selfhost.sql`
+- Config app: `lib\config.dart` (gitignored — berisi URL + keys, jangan commit)
+- Migrasi cloud → self-host selesai 2026-10-17
+- Akun: admin@posgrosir.local, kasir1@toko.com, bibi/bubu/baba@toko.com (password sementara `GrosirBaru2026!`)
+
+### Standar Rilis APK
+1. Naikkan versi di `pubspec.yaml` (misal `1.2.0+5` → `1.3.0+6`).
+2. Commit & `git push gitea main` (single remote Gitea; jangan commit APK ke repo).
+3. `flutter build apk --release` di `D:\HomeLabs\app-grosir` (jika gagal: `.gradlew --stop` + `flutter clean`).
+4. Verifikasi APK: file `build\app\outputs\flutter-apk\app-release.apk`; pastikan string `supa.gosambi.uk` ada di `libapp.so`.
+5. Instal ke HP: `adb -s fd683806 install -r app-release.apk`.
+6. Buat tag `v1.x.y` di Gitea + upload APK ke **Release** (`git.gosambi.uk/onie/app-grosir/releases`), jangan upload APK langsung ke repo Git.
+7. Catat versi baru di PRD.md ini + rule.md (singkat saja).
+
+### Device Testing
+- HP utama: **Realme RMX2061** (Android 11, device ID `fd683806`, package `com.grosir.app_grosir`)
+- HP admin kedua: sudah ada (untuk testing notifikasi multi-device)
