## 2. CHECKLIST VERIFIKASI KEBUTUHAN REFACTORING
- [ ] **TAHAP 1: ELIMINASI KERENTANAN KEAMANAN CRITICAL**
- [ ] Hapus/Amankan endpoint publik [`Debug.php`](file:///z:/everest_27jul/application/modules/penerimaan/controllers/Debug.php) dengan guard otorisasi `alowedAccess()` atau batasi hanya untuk environment development.
- [ ] Tuntaskan Kerentanan Insecure Deserialization (Object Injection) Massal:
- Ganti LEBIH DARI 40 instansiasi `unserialize(base64_decode())` di [`FollowUp.php`](file:///z:/everest_27jul/application/modules/penerimaan/controllers/FollowUp.php) dengan helper `decodeSafeSerializedBase64Array()`.
- Perbaiki eksekusi langsung dari input user: `unserialize(base64_decode($_GET['addParams']))` di [`ActivityReport.php` (Line 794)](file:///z:/everest_27jul/application/modules/penerimaan/controllers/ActivityReport.php#L794). Ini adalah vektor RCE (Remote Code Execution) kritis!
- [ ] Refactor method `doFollowup()` di [`FollowUp.php`](file:///z:/everest_27jul/application/modules/penerimaan/controllers/FollowUp.php#L4361): Terapkan sanitasi angka `(int)` dan sanitasi filter `sanitizeFilterExpression()` pada klausa SQL `id in (...)`.
- [ ] Amankan Input Global (XSS / SQLi Mitigation): Sanitasi ratusan variabel `$_GET` yang tersebar masif di [`ActivityReport.php`](file:///z:/everest_27jul/application/modules/penerimaan/controllers/ActivityReport.php) menggunakan fungsi pembantu `getSafeIntQueryParam()` atau ekivalennya.
- [ ] **TAHAP 2: PEMBERSIHAN BASE CONTROLLER & DOKUMENTASI MUTU (ISO 9001)**
- [ ] Bersihkan `die(__FILE__ . " gondes");` pada [`Modul_Controller.php`](file:///z:/everest_27jul/application/modules/penerimaan/controllers/Modul_Controller.php#L82).
- [ ] Tambahkan header `/** [AGENT_LOG] ... [/AGENT_LOG] */` pada seluruh class controller dan method public sesuai format standar Aturan 1 [`AGENTS.md`](file:///z:/everest_27jul/AGENTS.md).
- [ ] Bersihkan *debug code pollution* (`echo ""`, `cekHitam()`, `cekOrange()`, `arrprint()`) dari alur eksekusi produksi backend.
- [ ] **TAHAP 3: EARLY VALIDATION & INTEGRITAS AKUNTANSI (PSAK/IFRS & AGENTS.md)**
- [ ] Terapkan *Fail-Fast Early Validation Pattern* (Aturan 3.8 [`AGENTS.md`](file:///z:/everest_27jul/AGENTS.md)) pada `doFollowup()` dan `save()` sebelum inisialisasi sesi atau query DB.
- [ ] Pastikan wrapping transaksi DB `$this->db->trans_start()` dan `$this->db->trans_complete()` melindungi seluruh manipulasi data mutasi penerimaan piutang secara utuh.
- [ ] Pertahankan *Immutable Audit Trail* (tidak boleh ada `UPDATE`/`DELETE` langsung pada tabel mutasi GL/Jurnal penerimaan).
- [ ] **TAHAP 4: MODULARISASI GOD CLASS (ISO/IEC 25010)**
- [ ] Pecah method raksasa di [`FollowUp.php`](file:///z:/everest_27jul/application/modules/penerimaan/controllers/FollowUp.php) (23k baris) menjadi sub-helper/trait modular atau delegasikan ke model bisnis `Com*`.

> **CATATAN SISTEM**: Rencana ini dibuat sebagai panduan kerja dan acuan audit. Sesuai instruksi pengguna (*"JANGAN langsung dikerjakan dulu"*), **TIDAK ADA PERUBAHAN KODE YANG DIEKSEKUSI PADA TAHAP INI**. Eksekusi perbaikan baru akan dimulai setelah pengguna memberikan perintah persetujuan eksplisit.
