+# RFC Ringkas: FIFO Stock V2
+
+## Tujuan
+`fifo_stock_v2` adalah engine FIFO baru berbasis konfigurasi `Flag Group + Jalur` yang berjalan paralel dengan v1 tanpa memutus kompatibilitas `stock_allocations`, HPP, dan closing/reporting existing.
+
+## Prinsip
+- V1 tidak dihapus, V2 jalan paralel.
+- Semua operasi transactional.
+- FIFO sorting deterministic lintas tabel.
+- Default over-consume `ALLOW` (pending), exception dapat `BLOCK`.
+- Reflow idempotent.
+- Recalculate bisa memperbaiki drift `product_warehouses.qty`.
+
+## Komponen
+- `fifo_stock_v2_flag_groups`: master grouping flag produk.
+- `fifo_stock_v2_flag_members`: pemetaan flag -> group.
+- `fifo_stock_v2_traits`: trait sort per `table:date_column` (+ optional join date source).
+- `fifo_stock_v2_route_rules`: rule per `flag_group + lane + function + table`.
+- `fifo_stock_v2_overconsume_rules`: policy pending/over-consume.
+- `fifo_stock_v2_operation_log`: idempotency + audit operasi.
+- `fifo_stock_v2_reflow_runs` + checkpoints + shadow allocations: bulk reflow resumable/observable.
+
+## API Service
+- `Gather`: union cross-table berdasarkan route rules + trait sorting.
+- `Allocate`: alokasi lot FIFO ke usable.
+- `Rollback`: batalkan alokasi aktif.
+- `Reflow`: rollback penuh lalu allocate ulang (idempotent).
+- `Recalculate`: rekonsiliasi qty warehouse dari ledger FIFO.
+
+## Deterministic Sorting
+Urutan gather:
+1. `sort_at ASC` (dari trait `date_column`)
+2. `sort_priority ASC`
+3. `source_table ASC`
+4. `source_id ASC`
+
+Fallback waktu: `1970-01-01 00:00:00+00` bila tanggal null.
+
+## Compat Strategy
+- Tetap menulis ke `stock_allocations` dengan tambahan metadata:
+  - `engine_version` (`v1`/`v2`)
+  - `flag_group_code`
+  - `function_code`
+  - `idempotency_key`
+- Query lama yang bergantung `stockable_type/usable_type` tetap berjalan.
+
+## Migration Strategy
+1. Deploy schema + seed v2.
+2. Aktifkan shadow-run comparator v1 vs v2.
+3. Canary cutover per flag group.
+4. Full cutover jika parity aman.
+5. Jalankan bulk reflow existing data.
+
+## Acceptance Criteria Singkat
+- Parity mismatch terkendali pada aggregate + detail alokasi.
+- Tidak ada regression closing/HPP.
+- Drift qty warehouse turun signifikan pasca reflow.
+- Rollback via feature flag memungkinkan kembali ke v1.
