Placeholders
Any {placeholder} used in a business journey must be supplied by the inputs file.
If the business file uses {card_number}, the inputs file must provide card_number:
card_number: "4421"Missing placeholders fail before DialogAssert invokes the agent, so a typo costs you a validation error rather than a model call.
