## Summary Migrates the four ConPVP game board (scoreboard) gumps from legacy `Gump` to `DynamicGump`: - **`BRBoardGump`** (Bombing Run) — variable layout: row-per-team based on `Participants.Count`. Migrated to `DynamicGump`, `Singleton`, private constructor + `DisplayTo`, `SetNoClose()`. - **`CTFBoardGump`** (Capture the Flag) — variable layout: row-per-team filtered to only teams with a flag. Same migration shape. - **`DDBoardGump`** (Double Domination) — variable layout: row-per-team. Same migration shape. - **`KHBoardGump`** (King of the Hill) — variable layout: row-per-team. `sealed`. Same migration shape. ### Refresh-via-this decision For all four boards, **score data lives on the `*Game` / `*TeamInfo` objects, not the gump**. The gump just renders a snapshot of those values at the moment it is sent. The three call sites per board are: 1. `OnDoubleClick` on the in-world scoreboard item — one-shot manual open. 2. After death/kill score events (in `OnDeath`) — game logic pushes a fresh board to the dying player so they see updated scores. 3. End-of-game broadcast loop — sends final results to every participant. None of these are button-driven refreshes from inside the gump, and the gump owns no mutable state. Therefore each event allocates a fresh gump (now via `DisplayTo(...)`) rather than calling `SendGump(this)` on a long-lived instance — that pattern doesn't fit when the data source is external. The win comes from `DynamicGump`'s ref-struct builder writing directly to buffers, eliminating the legacy `GumpEntry` list allocations on every send. ### Mechanics - `: Gump` → `: DynamicGump`; layout moved from constructor to `BuildLayout(ref DynamicGumpBuilder)`. - `Closable = false` → `builder.SetNoClose()`. - Constructors are `private`; static `DisplayTo(Mobile, *Game, ...)` validates `mob?.NetState != null && game != null` before constructing. - Team-section-mode parameter (`section`) preserved on BR / CTF / DD as an optional `DisplayTo` param even though no current caller uses it. - The four `m_Game` / similar fields are renamed to `_game`; new fields use `_camelCase` per CLAUDE.md §12. - `AddBorderedText` / `AddColoredText` helpers became `static` and take `ref DynamicGumpBuilder`. - Updated all 12 internal call sites (3 per file) to go through `DisplayTo`. No external callers. - No `OnResponse` was defined on any of these gumps (the only button is a close button), so no `RelayInfo` signature changes were needed. Touches 4 game files, but only the gump classes — game logic (BR death/scoring, CTF flag handling, DD domination, KH king timer) is untouched. |

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
