+# Itens sem valores associados
+
+Esta entidade (`Item`) foi projetada para armazenar somente dados estáticos do item (nome, categoria, atributos e metadados) e **não** deve conter qualquer informação de preço/valor. Valores de compra, venda, lance, histórico de preços e afins pertencem ao modelo `Listing`.
+
+## Estrutura do Item (obrigatórios e opcionais)
+
+- `item_name` (obrigatório): Nome do item.
+- `category` (obrigatório): Categoria normalizada (ex.: `weapon`, `armor`, `helmet`, `accessory`, etc.).
+- `image_local_path` (opcional)
+- `image_url` (opcional)
+- `rarity` (opcional)
+- `level` (opcional)
+- `weight` (opcional)
+- `slots` (opcional)
+- `skill` (opcional)
+- `metadata` (opcional): Campos dinâmicos e específicos do item (atributos, servidores, tags, descrição). **Nunca inclua campos de valor aqui.**
+
+## Validação contra campos de valor
+
+Qualquer tentativa de incluir campos de valor/preço no `metadata` do item é **rejeitada** pela validação no servidor.
+
+Chaves bloqueadas (exemplos):
+
+- `price`, `prices`, `valor`, `value`, `sell_value`, `sellPrice`, `buy`, `buy_price`
+- Chaves de `Listing`: `price_pix`, `price_tibia_coins`, `price_gold_coins`, `initial_price_*`, `current_bid_amount`
+
+Mensagem retornada: _"Itens não possuem campos de valor/preço no cadastro. Use listings para preços."_
+
+## Por que separar?
+
+- Consistência: O mesmo item pode ter múltiplos anúncios com preços diferentes.
+- Integridade: Evita confusão e mistura de responsabilidades entre `Item` e `Listing`.
+- Evolução: Permite histórico de preços e leilões sem alterar o cadastro estático do item.
+
+## Fluxo recomendado
+
+1. **Cadastre o Item** com seus atributos e metadados (sem preços).
+2. **Crie Listings** para anunciar o item com preço, quantidade, leilão, etc.
+
+---
+
+Documentação criada para clarificar que `Item` é livre de valores associados e que as funções de criação/atualização validam esse contrato.
