    /// Public data contract layer for the Genesis Cordonel Interface (GCI).
    ///
    /// This class defines all Data Transfer Objects (DTOs) that are exposed
    /// to external consumers (e.g. TBF, UI, or other integration layers).
    ///
    /// Responsibilities:
    /// - Provide stable, dependency-free models for external usage
    /// - Decouple internal GCI implementation (GenesisMeter, Xylem libraries)
    ///   from external systems
    /// - Define request/response contracts for all supported operations
    /// - Contain mapping methods between public DTOs and internal domain models
    ///
    /// Architecture:
    /// External world (TBF / UI)
    ///     ↓
    /// GciPublicModels (this layer)
    ///     ↓
    /// Internal GCI API (InterfaceGCIToLaatzen, GenesisMeter, etc.)
    ///
    /// Notes:
    /// - Public models must NOT expose internal types (e.g. GenesisMeter, IPort, etc.)
    /// - All mapping between internal and external representations must be done here
    /// - DTOs are designed to be simple, serializable, and stable over time
    /// - Any change in internal implementation should not affect these models
    ///
    /// Pattern:
    /// Each operation follows a consistent structure:
    ///     Request  →  Operation  →  Result
    ///
    /// Example:
    ///     GciInitSlotRequest → InitSlot → GciInitSlotResult
    ///     GetSlot → GciSlotInfo
    ///     GetPcbId → GciGetPcbIdResult
    ///
    /// This layer acts as a boundary between domain logic and integration logic.
