+# IBL Registration Order — Location Generation Resilience Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Order header/detail/sample tetap tersimpan walau `generate_location` gagal; lokasi di-generate per-station (tidak abort di kegagalan pertama); error spesifik & actionable; endpoint retry tersedia.
+
+**Architecture:** Pindahkan `generate_location()` ke luar `trans_begin/commit` agar order tidak ikut rollback saat lokasi gagal. Extract core insert-location logic ke private method `_do_generate_location_for_stations()` yang dipakai bersama oleh `generate_location()` dan endpoint `retry_location()`. Tambahkan field opsional `location_warning` di response sukses.
+
+**Tech Stack:** PHP 7.x, CodeIgniter 3, MySQL. Tidak ada test runner — verifikasi manual via curl/Postman sesuai skenario UAT.
+
+---
+
+## File yang Diubah
+
+| File | Tipe | Keterangan |
+|---|---|---|
+| `application/controllers/mockup/fo/ibl_registration/Order.php` | Modify | Satu-satunya file yang disentuh |
+
+Semua perubahan ada di file ini:
+- Fungsi `save()` — ubah urutan pemanggilan, tambah `location_warning` di response
+- Fungsi `generate_location()` — delegasi ke private method baru
+- **Baru** private `_do_generate_location_for_stations()` — logika insert per-station
+- **Baru** public `retry_location()` — endpoint retry
+
+---
+
+## Task 1: Extract `_do_generate_location_for_stations()`
+
+Ini fondasi semua perubahan. Semua logika insert location per-station dipindah ke sini.
+
+**Files:**
+- Modify: `application/controllers/mockup/fo/ibl_registration/Order.php` (tambah setelah line 2275)
+
+- [ ] **Step 1.1 — Verifikasi titik sisip**
+
+  Buka file, konfirmasi line 2275 adalah baris `}` penutup `generate_location()` dan line 2277 adalah baris pertama `generate_req()`.
+
+  ```bash
+  sed -n '2273,2280p' /Users/fajrihardhitamurti/REPO_GITEA_IBL/BE_IBL/one-api-lab/application/controllers/mockup/fo/ibl_registration/Order.php
+  ```
+
+  Expected output:
+  ```
+    return $result;
+    }
+  
+    function generate_req($header_id, $req, $userid)
+  ```
+
+- [ ] **Step 1.2 — Sisipkan private method baru setelah baris penutup `generate_location()`**
+
+  Sisipkan blok berikut tepat setelah `}` penutup `generate_location()` (antara line 2275 dan 2277):

+  ```
+
+  Expected: `No syntax errors detected in ...Order.php`
+
+---
+
+## Task 2: Refactor `generate_location()` — delegasi ke private method
+
+Ganti seluruh isi `generate_location()` agar hanya bertugas query stations lalu memanggil `_do_generate_location_for_stations()`.
+
+**Files:**
+- Modify: `Order.php` line 2195–2275
+
+- [ ] **Step 2.1 — Catat baris pertama dan terakhir `generate_location()`**
+
+  ```bash
+  sed -n '2195,2275p' /Users/fajrihardhitamurti/REPO_GITEA_IBL/BE_IBL/one-api-lab/application/controllers/mockup/fo/ibl_registration/Order.php
+  ```
+
+  Pastikan range 2195–2275 masih sesuai (bisa bergeser setelah Task 1).
+
+- [ ] **Step 2.2 — Ganti isi `generate_location()`**
+
+  Ganti seluruh function body `generate_location` (dari baris `function generate_location` sampai `}` penutupnya) dengan:
+
+  ```php
+    function generate_location($header_id, $userid)
+    {
+      $sql = "SELECT T_SampleStationID, T_SampleStationName
+                  FROM t_orderdetail

+
+      $stations = $qry->result_array();
+      return $this->_do_generate_location_for_stations($stations, $header_id, $userid);
+    }
+  ```
+
+- [ ] **Step 2.3 — Syntax check**
+
+  ```bash
+  php -l /Users/fajrihardhitamurti/REPO_GITEA_IBL/BE_IBL/one-api-lab/application/controllers/mockup/fo/ibl_registration/Order.php
+  ```
+
+  Expected: `No syntax errors detected`
+
+---
+
+## Task 3: Restructure `save()` — pindah `generate_location` ke luar transaksi
+
+**Files:**
+- Modify: `Order.php` — dua titik di dalam function `save()`
+
+- [ ] **Step 3.1 — Hapus blok `generate_location` dari dalam transaksi (line 458–466)**
+
+  Hapus 9 baris berikut (termasuk baris kosong sesudahnya):
+
+  ```php
+      $fn_generate_location = $this->generate_location($header_id, $userid);
+      if (!$fn_generate_location['status']) {
+        $this->db_smartone->trans_rollback();
+        $message = $fn_generate_location['message'] ?? 'Terjadi kesalahan saat membuat lokasi';
+        if ($internal)
+          return ['status' => 'ERR', 'message' => $message];
+        $this->sys_error($message);
+        exit;
+      }
+  ```
+
+- [ ] **Step 3.2 — Tambahkan blok `generate_location` setelah `trans_commit()` (line 612)**
+
+  Setelah baris `$this->db_smartone->trans_commit();`, sisipkan:
+
+  ```php
+      $fn_generate_location = $this->generate_location($header_id, $userid);
+      $location_warning = null;
+      if ($fn_generate_location['has_failure']) {
+        $failed_parts = array_map(function ($f) {
+          return $f['name'] . ' (ID:' . $f['id'] . ')';
+        }, $fn_generate_location['failed']);
+        $failed_str = implode(', ', $failed_parts);
+        $location_warning = [
+          'has_error'       => true,
+          'message'         => "Order tersimpan sebagian. Gagal membuat lokasi: {$failed_str} belum punya mapping m_location aktif. Tindakan: tambahkan mapping lokasi aktif untuk station tersebut lalu retry generate location. OrderID: {$header_id}.",
+          'failed_stations' => $fn_generate_location['failed'],
+        ];
+      }
+  ```
+
+- [ ] **Step 3.3 — Tambahkan `location_warning` ke array `$dt_order`**
+
+  Di array `$dt_order` (sekitar line 772), tambahkan satu entry di akhir (sebelum `]`):
+
+  ```php
+      'report_url'       => $report_url,
+      'location_warning' => $location_warning,
+  ```
+
+  Sehingga `$dt_order` berakhir:
+  ```php
+      $dt_order = [
+        'status'           => 'OK',
+        'order_id'         => $x_data_array['T_OrderHeaderID'],
+        // ... field lainnya tidak berubah ...
+        'report_url'       => $report_url,
+        'location_warning' => $location_warning,
+      ];
+  ```
+
+- [ ] **Step 3.4 — Syntax check**
+
+  ```bash
+  php -l /Users/fajrihardhitamurti/REPO_GITEA_IBL/BE_IBL/one-api-lab/application/controllers/mockup/fo/ibl_registration/Order.php
+  ```
+
+  Expected: `No syntax errors detected`
+
+---
+
+## Task 4: Tambah endpoint `retry_location()`
+
+**Files:**
+- Modify: `Order.php` — tambah method baru sebelum penutup class (cari baris `}` paling akhir file)
+
+- [ ] **Step 4.1 — Temukan baris penutup class**
+
+  ```bash
+  tail -5 /Users/fajrihardhitamurti/REPO_GITEA_IBL/BE_IBL/one-api-lab/application/controllers/mockup/fo/ibl_registration/Order.php
+  ```
+
+  Catat nomor baris `}` penutup class.
+
+- [ ] **Step 4.2 — Sisipkan method `retry_location()` sebelum `}` penutup class**
+
+  ```php
+    function retry_location()

+## Task 5: UAT Manual — 3 Skenario
+
+Untuk setiap skenario, ganti `<TOKEN>`, `<HOST>`, dan payload sesuai environment dev.
+
+### Skenario 1 — Happy Path (semua mapping lengkap)
+
+- [ ] **Step 5.1 — Pastikan semua sample station pada order yang akan dites punya entry aktif di `m_location`**
+
+  ```sql
+  -- Jalankan di DB dev, ganti $order_detail_test sesuai test data
+  SELECT T_SampleStationID, T_SampleStationName,
+         M_LocationID, M_LocationIsActive
+  FROM t_samplestation
+  LEFT JOIN m_location ON M_LocationT_SampleStationID = T_SampleStationID
+                       AND M_LocationIsActive = 'Y'
+  WHERE T_SampleStationID IN (/* station ID yang akan dipakai test */);
+  ```
+
+  Expected: setiap station punya minimal 1 baris dengan `M_LocationIsActive = 'Y'`.
+
+- [ ] **Step 5.2 — Hit endpoint save**
+
+  ```bash
+  curl -s -X POST https://<HOST>/one-api-lab/mockup/fo/ibl_registration/order/save \
+    -H "Authorization: Bearer <TOKEN>" \
+    -H "Content-Type: application/json" \
+    -d '<payload lengkap dengan header/detail/sample>' | python3 -m json.tool
+  ```
+
+  Expected response:
+  ```json
+  {
+    "status": "OK",
+    "data": {
+      "status": "OK",
+      "order_id": <number>,
+      "noreg": "<string>",
+      "location_warning": null,
+      ...
+    }
+  }
+  ```
+
+- [ ] **Step 5.3 — Verifikasi `t_order_location` terisi**
+
+  ```sql
+  SELECT * FROM t_order_location WHERE T_OrderLocationT_OrderHeaderID = <order_id_dari_response>;
+  ```
+
+  Expected: ada row untuk setiap sample station order tersebut.
+
+---
+
+### Skenario 2 — Partial Failure (satu station tanpa mapping)
+
+- [ ] **Step 5.4 — Nonaktifkan mapping salah satu station (DEV only)**
+
+  ```sql
+  -- Catat station ID yang akan dinonaktifkan
+  UPDATE m_location 
+  SET M_LocationIsActive = 'N' 
+  WHERE M_LocationT_SampleStationID = <station_id_test>;
+  ```
+
+- [ ] **Step 5.5 — Hit endpoint save dengan order yang mencakup station tersebut**
+
+  ```bash
+  curl -s -X POST https://<HOST>/one-api-lab/mockup/fo/ibl_registration/order/save \
+    -H "Authorization: Bearer <TOKEN>" \
+    -H "Content-Type: application/json" \
+    -d '<payload>' | python3 -m json.tool
+  ```
+
+  Expected response:
+  ```json
+  {
+    "status": "OK",
+    "data": {
+      "status": "OK",
+      "order_id": <number>,
+      "location_warning": {
+        "has_error": true,
+        "message": "Order tersimpan sebagian. Gagal membuat lokasi: <NamaStation> (ID:<id>) belum punya mapping m_location aktif. Tindakan: ...",
+        "failed_stations": [
+          {"id": <station_id>, "name": "<nama>", "reason": "NO_MAPPING"}
+        ]
+      },
+      ...
+    }
+  }
+  ```
+
+- [ ] **Step 5.6 — Verifikasi order tersimpan di DB**
+
+  ```sql
+  SELECT T_OrderHeaderID, T_OrderHeaderLabNumber 
+  FROM t_orderheader WHERE T_OrderHeaderID = <order_id>;
+  ```
+
+  Expected: ada 1 row — order tersimpan meski lokasi gagal.
+
+- [ ] **Step 5.7 — Verifikasi station lain tetap punya lokasi**
+
+  ```sql
+  SELECT T_OrderLocationT_SampleStationID
+  FROM t_order_location 
+  WHERE T_OrderLocationT_OrderHeaderID = <order_id>;
+  ```
+
+  Expected: ada row untuk station yang mapping-nya aktif, tidak ada row untuk station yang dinonaktifkan.
+
+- [ ] **Step 5.8 — Verifikasi error tercatat di `error_log_order`**
+
+  ```sql
+  SELECT * FROM error_log_order 
+  WHERE ErrorLogOrderCode = 'LOCATION_NO_MAPPING'
+  ORDER BY ErrorLogOrderCreated DESC LIMIT 5;
+  ```
+
+  Expected: ada entry baru dengan `ErrorLogOrderData` berisi order_id dan station_id yang gagal.
+
+---
+
+### Skenario 3 — Retry sukses setelah mapping diperbaiki
+
+- [ ] **Step 5.9 — Aktifkan kembali mapping yang dinonaktifkan di Step 5.4**
+
+  ```sql
+  UPDATE m_location 
+  SET M_LocationIsActive = 'Y' 
+  WHERE M_LocationT_SampleStationID = <station_id_test>;
+  ```
+
+- [ ] **Step 5.10 — Hit endpoint `retry_location`**
+
+  ```bash
+  curl -s -X POST https://<HOST>/one-api-lab/mockup/fo/ibl_registration/order/retry_location \
+    -H "Authorization: Bearer <TOKEN>" \
+    -H "Content-Type: application/json" \
+    -d '{"order_id": <order_id_dari_skenario_2>}' | python3 -m json.tool
+  ```
+
+  Expected response:
+  ```json
+  {
+    "status": "OK",
+    "data": {
+      "order_id": <number>,
+      "succeeded": [{"id": <station_id>, "name": "<nama>"}],
+      "failed": [],
+      "message": "Retry selesai. 1 berhasil, 0 gagal."
+    }
+  }
+  ```
+
+- [ ] **Step 5.11 — Verifikasi `t_order_location` kini lengkap**
+
+  ```sql
+  SELECT T_OrderLocationT_SampleStationID, T_OrderLocationM_LocationID
+  FROM t_order_location 
+  WHERE T_OrderLocationT_OrderHeaderID = <order_id>;
+  ```
+
+  Expected: ada row untuk semua station, termasuk yang sebelumnya gagal.
+
+- [ ] **Step 5.12 — Hit retry_location lagi (idempotency check)**
+
+  ```bash
+  curl -s -X POST https://<HOST>/one-api-lab/mockup/fo/ibl_registration/order/retry_location \
+    -H "Authorization: Bearer <TOKEN>" \
+    -H "Content-Type: application/json" \
+    -d '{"order_id": <order_id>}' | python3 -m json.tool
+  ```
+
+  Expected:
+  ```json
+  {
+    "status": "OK",
+    "data": {
+      "message": "Semua lokasi sudah terbentuk untuk order ini.",
+      "succeeded": [],
+      "failed": []
+    }
+  }
+  ```

+# Design: IBL Registration Order — Location Generation Resilience
+
+**Date:** 2026-05-19  
+**Scope:** DEV only. No production changes.  
+**File:** `application/controllers/mockup/fo/ibl_registration/Order.php`  
+**Endpoint:** `POST /one-api-lab/mockup/fo/ibl_registration/order/save`
+
+---
+
+## Problem
+
+Saat ini jika `generate_location()` gagal (mapping `m_location` aktif tidak ditemukan untuk suatu sample station), seluruh order — termasuk header, detail, dan sample yang sudah valid — ikut di-rollback. Response ke FE berupa error generik:
+
+> "Terjadi kesalahan saat menyimpan data lokasi"
+
+Akibatnya pelayanan stuck dan operator tidak tahu tindakan apa yang harus dilakukan.
+
+Ada juga silent bug: jika `m_location` tidak ditemukan, `$qry->row()->loc_id` bernilai null, dan INSERT tetap dijalankan dengan `loc_id = null` — bukan ditangkap sebagai "mapping tidak ada".
+
+---
+
+## Goals
+
+1. Order utama (header/detail/sample) tetap tersimpan walau `generate_location` gagal.
+2. Jika hanya sebagian station gagal, station lain tetap di-generate lokasinya.
+3. Error message dibuat spesifik dan actionable — dicatat di backend log dan dikirim ke FE via field opsional `location_warning`.
+4. Tidak ada perubahan wajib di FE (field `location_warning` opsional, diabaikan FE saat ini).
+5. Endpoint retry tersedia untuk dev agar ops bisa generate ulang lokasi yang belum terbentuk.
+
+---
+
+## Architecture
+
+### Perubahan Struktur Transaksi di `save()`
+
+**Sebelum:**
+```
+trans_begin()
+  save_order_header()
+  save_order_detail()
+  generate_sample_lab()
+  generate_location()   ← di dalam transaksi, gagal = rollback semua
+  generate_req()
+  update_preregister_promise()
+  save_delivery()
+trans_commit()
+```
+
+**Sesudah:**
+```
+trans_begin()
+  save_order_header()
+  save_order_detail()
+  generate_sample_lab()
+  generate_req()
+  update_preregister_promise()
+  save_delivery()
+trans_commit()                ← order tersimpan permanen di sini
+
+generate_location()           ← di luar transaksi, mini-transaction sendiri
+  → sukses semua  : location_warning = null
+  → sebagian gagal: log error, location_warning = {has_error, message, failed_stations}
+  → semua gagal   : log error, location_warning = {has_error, message, failed_stations}
+
+sys_ok($dt_order)             ← selalu OK, location_warning opsional
+```
+
+---
+
+## Component Changes
+
+### A. `save()` (line 423–466)
+
+1. Hapus `$fn_generate_location` dari dalam blok transaksi.
+2. Setelah `trans_commit()`, panggil `generate_location($header_id, $userid)`.
+3. Evaluasi result:
+   - Jika `$fn_generate_location['has_failure']` true → jalankan `insert_log_error()` untuk tiap station gagal, set `$location_warning`.
+   - Jika semua sukses → `$location_warning = null`.
+4. Tambahkan `'location_warning' => $location_warning` ke array `$dt_order`.
+
+### B. `generate_location($header_id, $userid)`
+
+Ubah logic loop station:
+
+- **Check null mapping:** Setelah query `m_location`, cek apakah `$qry->row()` null. Jika null → tambah ke `$failed[]` dengan `reason = 'NO_MAPPING'`, **lanjut** ke station berikutnya (jangan insert).
+- **Check query error:** Jika `$qry === false` → tambah ke `$failed[]` dengan `reason = 'QUERY_ERROR'`, lanjut.
+- **Check insert error:** Jika INSERT gagal → tambah ke `$failed[]` dengan `reason = 'INSERT_ERROR'`, lanjut.
+- **Sukses:** Tambah ke `$succeeded[]`.
+
+Return structure:
+```php
+[
+  'has_failure'  => bool,
+  'succeeded'    => [['id' => int, 'name' => str], ...],
+  'failed'       => [['id' => int, 'name' => str, 'reason' => str], ...],
+]
+```
+
+Format pesan kegagalan (dibangun di `save()` setelah generate_location):
+```
+"Order tersimpan sebagian. Gagal membuat lokasi: {NamaStation} (ID:{id}) belum punya 
+mapping m_location aktif. Tindakan: tambahkan mapping lokasi aktif untuk station 
+tersebut lalu retry generate location. OrderID: {header_id}."
+```
+
+### C. Logging Backend
+
+Untuk tiap station gagal, panggil `insert_log_error()` ke tabel `error_log_order`:
+- `ErrorLogOrderCode`: `'LOCATION_NO_MAPPING'` / `'LOCATION_QUERY_ERROR'` / `'LOCATION_INSERT_ERROR'`
+- `ErrorLogOrderFnName`: `'order/generate_location'`
+- `ErrorLogOrderDescription`: SQL atau keterangan
+- `ErrorLogOrderData`: `json_encode(['order_id' => $header_id, 'station_id' => $id, 'station_name' => $name])`
+
+### D. Field `location_warning` di Response
+
+Ditambahkan ke `$dt_order` (di dalam `data`). FE saat ini mengabaikannya; tersedia untuk update FE berikutnya.
+
+```json
+// Jika ada kegagalan:
+"location_warning": {
+  "has_error": true,
+  "message": "Order tersimpan sebagian. Gagal membuat lokasi: ...",
+  "failed_stations": [
+    {"id": 25, "name": "Dental/Panoramic", "reason": "NO_MAPPING"}
+  ]
+}
+
+// Jika semua sukses:
+"location_warning": null
+```
+

+
+## New Endpoint: `retry_location`
+
+**Route:** `POST /mockup/fo/ibl_registration/order/retry_location`  
+**Method:** `retry_location()` di class `Order`
+
+### Input
+```json
+{ "order_id": 123456 }
+```
+
+### Flow
+1. Validasi login (`isLogin`).
+2. Query semua `T_SampleStationID` terkait order dari `t_orderdetail` (join chain yang sama dengan `generate_location`).
+3. Filter: ambil hanya station yang **belum ada** di `t_order_location` untuk order tersebut.
+4. Jalankan logic generate location (private method `_do_generate_location_for_stations($stations, $header_id, $userid)`) — sama dengan yang dipakai `generate_location`.
+5. Return summary.
+
+### Output
+```json
+{
+  "status": "OK",
+  "data": {
+    "order_id": 123456,
+    "succeeded": [{"id": 10, "name": "Lab Utama"}],
+    "failed": [{"id": 25, "name": "Dental/Panoramic", "reason": "NO_MAPPING"}],
+    "message": "Retry selesai. 1 berhasil, 1 gagal."
+  }
+}
+```
+
+---
+
+## Refactor Internal
+
+Extract logic insert location per-station ke private method `_do_generate_location_for_stations(array $stations, int $header_id, int $userid): array` — dipakai oleh `generate_location()` dan `retry_location()`.
+
+---
+
+## UAT Scenarios (DEV)
+
+| Skenario | Kondisi | Expected Result |
+|---|---|---|
+| 1. Happy path | Semua station punya mapping aktif | `status: OK`, `location_warning: null` |
+| 2. Partial failure | 1 station tanpa mapping aktif | `status: OK`, `location_warning.has_error: true`, station lain tetap tersimpan di `t_order_location` |
+| 3. Retry sukses | Mapping diperbaiki, hit `retry_location` | `succeeded` berisi station yang sebelumnya gagal, `failed: []` |
+
+---
+
+## Constraints
+
+- Dev only. Tidak ada perubahan production.
+- Tidak ada perubahan schema DB (tabel `t_order_location` dan `error_log_order` tidak berubah).
+- Tidak ada perubahan FE yang wajib.
+- Perubahan hanya di `Order.php` pada path `mockup/fo/ibl_registration/`.
