Schema: - warehouses (multi-warehouse, code unique per company, is_default) - part_batches (lot per receipt, qty_in/qty_remaining, buy_price, FIFO-indexed) - warehouse_events (immutable ledger: opening/receipt/issue/transfer/adjustment/write_off) - part_reservations (per-WO allocations from specific batches, active/consumed/released) - companies.default_warehouse_id + parts.qty_reserved Backfill: 1 default warehouse + 1 opening batch per existing part per company. WarehouseService: - receive / issue (FIFO) / reserve / release / consume / transfer / adjust - DB::transaction + lockForUpdate on batch rows - InsufficientStockException with requested + available context - Auto-syncs parts.qty as aggregate cache (source of truth = sum(qty_remaining)) WO integration: - WorkOrderPart created/updated → reserve from FIFO batches - WorkOrderPart deleted → release - WorkOrder status=done → consume reservations into issue events - WorkOrder status=cancelled → release reservations Filament: - WarehouseResource (CRUD) - BatchesRelationManager on PartResource (FIFO list with qty_remaining + cost) - "Recepție" action on parts list → calls WarehouseService::receive - qty_reserved column added on parts list Tests (8 new, all pass): - receipt creates batch + event - FIFO order verified across 3 batches with different received_at - InsufficientStockException on over-issue - Reservations block other reservations but don't deplete on-hand - WO done consumes; WO cancelled releases - Batches tenant-isolated - Transfer between warehouses with weighted-avg cost Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
