## Validasi staging (perintah)

```text
php spark api:staging-validate
php spark api:staging-validate --with-uploads
```

Laporan JSON: `writable/staging/last-validation.json`.

## Ringkasan implementasi CI4 (saat ini)

- API mobile: `App\Services\Mobile\MobileJsonService` + `App\Controllers\Api\MobileJsonController`.
- Rute: `POST /api/mobile/*` dan alias **`POST /json/*`** (kompatibilitas path CI3).
- Admin UI dasar: `GET /admin` + layout di `app/Views/layouts/*`, aset TailAdmin di `public/assets/tailadmin/`.
- Upload mobile: `public/assets/uploads/{dokcuti,aktifitas,absen,pengguna}`.

## Asumsi engineering

- Charset API mengikuti `LegacyUtf8Encoder` (setara `utf8ize` legacy untuk string ISO-8859-1).
- `save_istirahat`: jika `mulai` dan `selesai` keduanya kosong, CI4 **tidak** menjalankan `UPDATE` (menghindari error); legacy CI3 sebenarnya rawan *undefined variable* — perilaku aman di CI4.
