1. inventory.service.ts (API production code) surfaces requiredLevel in
its response DTO. Task 3 deletes the entity column, so this would
fail to compile and keep shipping a dead field. No task covered it:
Task 10 swept only test fixtures, Task 12 only the web model. Folded
into Task 10 as a new Step 0.
2. No web-side sweep task existed. Task 12's model changes break
CharacterResponse/InventoryItem fixtures in app.spec.ts,
world.store.spec.ts, and inventory.store.spec.ts, none of which
Tasks 13-16 touch. Added Task 17 mirroring Task 10's sweep rule.
