⌘ data/Models.kt (assistant section)

@Serializable
data class AssistantChatRequest(
    val message: String,
)

@Serializable
data class DraftBooking(
    @SerialName("walker_id") val walkerId: String,
    @SerialName("dog_name") val dogName: String? = null,
    @SerialName("start_time") val startTime: String? = null,
    @SerialName("duration_minutes") val durationMinutes: Int = 30,
)

@Serializable
data class AssistantReply(
    val reply: String,
    @SerialName("suggested_walkers") val suggestedWalkers: List<String> = emptyList(),
    @SerialName("draft_booking") val draftBooking: DraftBooking? = null,
)

The same `@SerialName` dance you've done since Module 4: snake_case JSON in, camelCase Kotlin out. `draftBooking` is nullable — the backend only fills it in when it's confident enough to pre-fill a booking.
