## Summary Migrates 10 player-facing legacy `Gump` subclasses for holiday and decorative items to the modern `DynamicGump` / `StaticGump<T>` system. All migrated gumps are `Singleton`, use private constructors gated by static `DisplayTo(...)` entry points (empty-gump rule, CLAUDE.md §13), and replace legacy `m_X` fields with `_x` per coding standards. Per-gump base type and rationale: - **Mistletoe.cs** — `MistletoeAddonGump` -> `StaticGump<MistletoeAddonGump>`. Fixed re-deed confirmation layout. - **StValentinesBears.cs** — Renamed `InternalGump` -> `StValentinesBearsGump`, base `StaticGump<T>`. Fixed sign-bear layout with three text entries; legacy `m_Bear` -> `_bear`. Switched legacy `AddTextEntry(..., size)` -> `AddTextEntryLimited(...)` (modern API split). - **Wreath.cs** — `WreathAddonGump` -> `StaticGump<WreathAddonGump>`. Fixed re-deed confirmation layout. - **HolidayPottedPlant.cs** — Renamed `InternalGump` -> `HolidayPottedPlantGump`, base `StaticGump<T>`. Fixed plant-picker layout. - **SnowStatue.cs** — Renamed `InternalGump` -> `SnowStatueGump`, base `StaticGump<T>`. Fixed statue-picker layout. Dropped unused `Mobile from` ctor arg. - **TapestryOfSosaria.cs** — Renamed `InternalGump` -> `TapestryOfSosariaGump`, base `StaticGump<T>`. Single image, fixed. - **HouseRaffleDeed.cs** — `WritOfLeaseGump` -> `DynamicGump`. Description HTML is computed per-instance from deed expiration / days-left, so layout text varies per instance. Added `Singleton => true` (was missing implicitly via legacy default). - **SpecialScroll.cs** — Renamed `InternalGump` -> `SpecialScrollGump`, base `DynamicGump`. **Cliloc rule**: `_scroll.Message`, `_scroll.Title`, `_scroll.SkillLabel` are dynamic cliloc numbers per scroll type — `AddHtmlLocalized` bakes the cliloc number into the cached layout, so `StaticGump<T>` cannot cache it. - **BallotBox.cs** — Renamed `InternalGump` -> `BallotBoxGump`, base `DynamicGump`. Layout shape varies: variable topic-line count, owner-vs-voter buttons, and vote-tally bars all add/remove elements. Legacy `m_Box` -> `_box`. Updated the `TopicPrompt` callbacks to call `BallotBoxGump.DisplayTo(...)` instead of allocating a new gump directly. - **AquariumGump.cs** — `AquariumGump` -> `DynamicGump`. Per-page layout depends on each item's `LabelNumber` and (for `BaseFish`) `GetDescription()` cliloc — those vary per fish/decoration. Two `DisplayTo` overloads (auto-detect access vs explicit edit flag) to mirror the original two call sites in `Aquarium.cs`. Legacy `m_Aquarium` -> `_aquarium`. ### Skipped - **HouseRaffleManagementGump.cs** — Skipped as **staff-only**. Only invoked via `ManagementEntry` context entry inside `HouseRaffleStone.cs`, gated by `from.AccessLevel >= AccessLevel.Seer`. Per task instructions, staff-only gumps are out of scope for this PR. ### External callers updated - `Aquarium.cs` — Two `new AquariumGump(...)` sites swapped to `AquariumGump.DisplayTo(...)`. All other migrated inner classes were nested in the same file and only had local references, which were updated to call the new `DisplayTo(...)` static entry point. |

Building/Publishing
Interactive Mode (Recommended for new users)
Run ./publish.cmd (Windows) or ./publish.sh (Linux/macOS) with no arguments to launch the guided build tool. It will:
- Check prerequisites (.NET SDK, native libraries)
- Walk you through configuration and platform selection
- Build and publish the server to the
Distributiondirectory - Show deployment instructions for cross-compiled builds
Command Line
./publish.cmd [release|debug] [os] [arch]
os- Supported operating systemsarchx64- Intel/AMD 64-bitarm64- ARM 64-bit
Linux Prerequisites
Fedora, CentOS, RHEL, etc
dnf upgrade --refresh -y
# CentOS does not come with EPEL enabled
dnf install -y epel-release epel-next-release
dnf install -y findutils libicu libdeflate-devel zstd libargon2-devel liburing-devel

Running the Server
- Follow the publish instructions
- The
Distributiondirectory is portable — copy it to your production server for deployment - Run
ModernUO.exeordotnet ModernUO.dllfrom theDistributiondirectory - On first run, the server will prompt you to configure game data file locations
