Business logic helpers for UCP Messages (errors, warnings, info).
Messages communicate session state to agents and buyers. Each message has a type discriminator that determines which fields are applicable.
Message Types
:error- Indicates a problem that prevents checkout completion:warning- Indicates a potential issue that may need attention:info- Provides informational context
Example

"code" => "out_of_stock",

"path" => "$.line_items[0]"
})
# Warning message

"code" => "price_changed",
