## What changed - Add a `ResponseItemId` type that generates item-specific prefixes with UUIDv7 suffixes and use it across response items. - Keep deserialization permissive for legacy histories, but omit empty or unprefixed item IDs from HTTP and WebSocket requests. - Export the new type in the generated TypeScript protocol schema. ## Testing - Cover prefixed ID generation, legacy deserialization, prefix recognition, and outbound request filtering.
