# Sub-Task 5: CraftingTab Design Phase Compatibility (Bug 7)

## Scope
- **Components affected**:
  - `components/CraftingTab.tsx` (Design phase section)
  - Enchantment data sources (e.g., `data/enchantments.ts`)
  - Player inventory state (to check owned items)
- **Files potentially affected**:
  - `utils/craftingUtils.ts` (enchantment compatibility logic)
  - `types/crafting.ts` (enchantment-item compatibility types)
  - `store/inventorySlice.ts` or similar for player item data

## Acceptance Criteria
1. In CraftingTab Design phase, only enchantments compatible with items the player currently owns are shown (verify by checking UI with different inventory states)
2. Compatibility is determined by enchantment type (e.g., weapon enchantments only show if player owns weapons)
3. No performance issues when filtering enchantments

## Dependencies
- None (independent, but Sub-Task 6 depends on this if modifying same CraftingTab file)

## Estimated Complexity
- Medium (data filtering + UI update)
