## 2. DAFTAR FUNGSI & LOGIKA BISNIS (REVERSE ENGINEERING)

### 2.1 Base Controller & Configuration

#### [Modul_Controller.php](file:///c:/xampp/htdocs/new_san_variant/application/modules/penerimaanprojek/controllers/Modul_Controller.php)
- **Fungsi `__construct()`**: Load config `coTransaksiUi`, `coTransaksiCore`, `coTransaksiLayout`, `coTransaksiValues`.

---

### 2.2 Entry Milestone Billing & AR Matcher

#### [_processSelectNota.php](file:///c:/xampp/htdocs/new_san_variant/application/modules/penerimaanprojek/controllers/_processSelectNota.php)
- **Fungsi Milestone AR Matcher**:
  - *Input*: `POST` ID Proyek (`projekID`), ID Pelanggan, Nomor Sertifikat Progress Pekerjaan.
  - *Logic*: Menampilkan sisa klaim piutang termin proyek, potongan retensi jaminan (misal 5% retensi), serta pengakuan pendapatan termin.

#### [Create.php](file:///c:/xampp/htdocs/new_san_variant/application/modules/penerimaanprojek/controllers/Create.php)
- **Fungsi `index()`, `preview()`, `save()`**: Entry draf penerimaan kas/bank dari klaim termin proyek.

---

### 2.3 Executing & FollowUp Approval

#### [FollowUp.php](file:///c:/xampp/htdocs/new_san_variant/application/modules/penerimaanprojek/controllers/FollowUp.php)
- **Fungsi `doFollowup()`** *(Execution Project Receipt)*:
  - *Query & Models*:
    1. **Project AR Rebalancing**: Mengurangi sisa saldo piutang termin proyek pada `transaksi_values`.
    2. **Jurnal Penerimaan Proyek**: Memanggil `ComJurnal` mencatat Kas/Bank (D) & Piutang Retensi (D jika ada) vs Piutang Termin Proyek (K) & Uang Muka Proyek (D jika dipotong).
    3. **Registry Update**: Log step registrasi di `transaksi_registry`.
