+# Runbook Cutover Stok Telur Historis Kandang ke Gudang Farm
+
+## Tujuan
+
+Runbook ini dipakai untuk memindahkan **stok telur historis yang masih on-hand di gudang kandang** ke **gudang farm** secara aman, audit-able, dan reversible.
+
+Cutover dilakukan dengan **transfer stok eksplisit**, bukan dengan mengubah `recording_eggs.product_warehouse_id` historis.
+
+## Scope
+
+Runbook ini hanya untuk:
+- stok telur historis kandang-level yang masih punya saldo on-hand
+- lokasi yang masuk kategori **clean cutover**
+- lokasi yang sudah punya gudang farm
+
+Runbook ini **tidak** dipakai untuk:
+- lokasi overlap seperti `Cijangkar`
+- koreksi histori `recording_eggs`
+- migrasi stok non-telur
+
+## Kebijakan yang Dikunci
+
+- Sumber qty yang dipindah adalah **`product_warehouses.qty` saat cutover**
+- Perintah dijalankan **per lokasi**
+- Wajib mulai dari `dry-run`
+- `--apply` hanya boleh dijalankan setelah review dry-run dan SQL checklist
+- Lokasi overlap tidak ikut otomatis kecuali ada approval khusus dan `--include-overlap`
+- Rollback hanya boleh dilakukan jika transfer hasil cutover belum dipakai transaksi turunan
+
+## Lokasi Fase 1
+
+Lokasi yang boleh dieksekusi pada fase pertama:
+- `Jamali`
+- `Cantilan`
+- `Darawati`
+- `Tamansari`
+
+Lokasi yang harus ditahan:
+- `Cijangkar`
+
+## Prasyarat
+
+Sebelum eksekusi, pastikan:
+- backend sudah ter-deploy dengan command [main.go](/Users/macbookair/Documents/coding/projects/LTI-ERP/lti-api/cmd/migrate-legacy-egg-stock-to-farm/main.go)
+- reusable transfer core sudah ikut ter-deploy:
+  - [transfer.service.go](/Users/macbookair/Documents/coding/projects/LTI-ERP/lti-api/internal/modules/inventory/transfers/services/transfer.service.go)
+  - [system_transfer.go](/Users/macbookair/Documents/coding/projects/LTI-ERP/lti-api/internal/modules/inventory/transfers/services/system_transfer.go)
+- migrasi farm stock attribution sebelumnya sudah terpasang
+- akses database target sudah tersedia
+- environment target memakai SSL bila RDS mewajibkan, contoh:
+  - `DB_SSLMODE=require`
+
+## Catatan Output Command
+
+Mode `--output table` adalah mode operasional yang direkomendasikan.
+
+Mode `--output json` bisa dipakai, tetapi pada environment saat ini output JSON masih dapat didahului log bootstrap aplikasi atau SQL logger. Untuk review manual gunakan `table`. Untuk parsing otomatis, filter payload mulai dari `{`.
+
+## Format Command
+
+### Dry-run
+
+```bash
+DB_SSLMODE=require go run ./cmd/migrate-legacy-egg-stock-to-farm \
+  --location-name Jamali \
+  --output table
+```
+
+### Apply
+
+```bash
+DB_SSLMODE=require go run ./cmd/migrate-legacy-egg-stock-to-farm \
+  --location-name Jamali \
+  --cutover-date 2026-04-07 \
+  --apply \
+  --output table
+```
+
+### Rollback Preview
+
+```bash
+DB_SSLMODE=require go run ./cmd/migrate-legacy-egg-stock-to-farm \
+  --rollback-run-id <run_id> \
+  --output table
+```
+
+### Rollback Apply
+
+```bash
+DB_SSLMODE=require go run ./cmd/migrate-legacy-egg-stock-to-farm \
+  --rollback-run-id <run_id> \
+  --apply \
+  --output table
+```
+
+## Arti `run_id`
+
+Setiap dry-run/apply menghasilkan `run_id`, misalnya:
+
+```text
+egg-cutover-20260407T130344.220407000Z
+```
+
+`run_id` ini wajib disimpan karena dipakai untuk:
+- audit hasil cutover
+- query verifikasi
+- rollback
+
+## Prosedur Eksekusi Per Lokasi
+
+### 1. Persiapan
+
+Tentukan:
+- `location_name`
+- `cutover_date`
+- operator yang bertanggung jawab
+
+Contoh:
+- lokasi: `Jamali`
+- cutover date: `2026-04-07`
+
+### 2. Jalankan Dry-run
+
+```bash
+DB_SSLMODE=require go run ./cmd/migrate-legacy-egg-stock-to-farm \
+  --location-name Jamali \
+  --output table
+```
+
+Yang harus dicek pada hasil dry-run:
+- status lokasi `CLEAN_CUTOVER`
+- semua baris yang akan dipindah punya `status=eligible`
+- gudang tujuan adalah gudang farm lokasi tersebut
+- qty yang dipindah masuk akal dan sesuai saldo on-hand aktual
+- tidak ada `missing_farm_warehouse`
+- tidak ada `overlap_location`
+
+### 3. Jalankan Checklist SQL Before
+
+Gunakan file:
+- [legacy_egg_cutover_verification_checklist.sql](/Users/macbookair/Documents/coding/projects/LTI-ERP/lti-api/docs/sql/legacy_egg_cutover_verification_checklist.sql)
+
+Minimal pastikan:
+- lokasi memang clean cutover
+- stok telur kandang positif masih ada
+- gudang farm ada
+- belum ada transfer `EGG_FARM_CUTOVER` aktif untuk lokasi yang sama pada run yang akan dipakai
+
+### 4. Simpan Evidence Sebelum Apply
+
+Simpan:
+- output dry-run
+- hasil query before
+- nama operator
+- waktu eksekusi
+
+Disarankan simpan dalam ticket / change record.
+
+### 5. Jalankan Apply
+
+```bash
+DB_SSLMODE=require go run ./cmd/migrate-legacy-egg-stock-to-farm \
+  --location-name Jamali \
+  --cutover-date 2026-04-07 \
+  --apply \
+  --output table
+```
+
+Setelah apply, simpan:
+- `run_id`
+- seluruh row dengan `transfer_id`
+- movement number yang terbentuk
+
+### 6. Jalankan Checklist SQL After
+
+Masih menggunakan file:
+- [legacy_egg_cutover_verification_checklist.sql](/Users/macbookair/Documents/coding/projects/LTI-ERP/lti-api/docs/sql/legacy_egg_cutover_verification_checklist.sql)
+
+Minimal pastikan:
+- transfer header/detail tercatat untuk `run_id`
+- qty source berkurang sesuai transfer
+- qty farm bertambah sesuai transfer
+- total gabungan source+dest per produk per lokasi tetap sama
+- stok eligible tidak lagi tersedia di gudang kandang
+- stok telur sekarang tersedia di gudang farm
+
+### 7. Smoke Test UI
+
+Lakukan minimal:
+- buka product stock farm untuk lokasi tersebut
+- pastikan produk telur hasil migrasi muncul
+- buat SO farm-level dan pastikan opsi produk telur tersedia
+- pastikan recording telur baru setelah cutover tetap langsung masuk ke gudang farm
+
+### 8. Tutup Eksekusi
+
+Catat hasil akhir:
+- sukses/gagal
+- `run_id`
+- lokasi
+- tanggal cutover
+- operator
+- link ke evidence SQL/UI
+
+## Kriteria Go / No-Go
+
+### Boleh lanjut apply bila:
+
+- dry-run menunjukkan hanya row yang memang expected
+- lokasi `CLEAN_CUTOVER`
+- gudang farm valid
+- query before menunjukkan tidak ada anomaly blocking
+
+### Wajib stop bila:
+
+- lokasi terdeteksi `OVERLAP`
+- ada qty aneh atau tidak sesuai data lapangan
+- gudang farm tidak ada
+- ada transfer lama serupa yang belum direkonsiliasi
+- setelah apply terjadi selisih total source+dest
+
+## Rollback Runbook
+
+### Kapan rollback boleh dilakukan
+
+Rollback boleh jika:
+- transfer hasil cutover belum dipakai transaksi turunan
+- verifikasi after menunjukkan issue yang membuat hasil cutover tidak dapat diterima
+
+### Langkah rollback
+
+1. Preview rollback:
+
+```bash
+DB_SSLMODE=require go run ./cmd/migrate-legacy-egg-stock-to-farm \
+  --rollback-run-id <run_id> \
+  --output table
+```
+
+2. Jalankan query rollback readiness pada file audit/helper SQL.
+3. Jika aman, apply rollback:
+
+```bash
+DB_SSLMODE=require go run ./cmd/migrate-legacy-egg-stock-to-farm \
+  --rollback-run-id <run_id> \
+  --apply \
+  --output table
+```
+
+4. Jalankan ulang query verifikasi after rollback.
+
+### Kapan rollback akan gagal by design
+
+Rollback memang harus gagal jika:
+- transfer hasil cutover sudah dipakai sales/recording/transaksi turunan
+- sudah ada `stock_allocations` consume aktif terhadap `STOCK_TRANSFER_IN`
+
+## Urutan Rollout yang Direkomendasikan
+
+### Dev
+
+1. Dry-run per lokasi
+2. Review SQL before
+3. Apply per lokasi
+4. SQL after
+5. Smoke UI
+6. Simpan `run_id`
+
+### Production
+
+1. Freeze operasional lokasi target bila perlu
+2. Dry-run
+3. Review by dev + ops + finance/stock owner
+4. Apply
+5. SQL after
+6. Smoke UI
+7. Release lokasi berikutnya
