## Summary Migrates the eight concrete New Guild System gumps (CreateGuild, GuildInfo, GuildMemberInfo, GuildRoster, GuildDiplomacy, WarDeclaration, GuildAdvancedSearch, GuildInvitationRequest) and three abstract bases (BaseGuildGump, BaseGuildListGump, OtherGuildInfo) from the legacy `Gump` class to `DynamicGump`. Layout work moves from constructor-side `AddX(...)` calls into `BuildLayout(ref DynamicGumpBuilder builder)` — the abstract `BaseGuildGump` now provides a `BuildContent` callout for shared tab-strip chrome, and `BaseGuildListGump<T>` adds another `BuildListExtras` hook so subclasses can paint highlighted titles after the filter/sort/pagination chrome. The headline win is the **self-refresh pattern** on the list gumps and diplomacy advanced search. Previously each filter/sort/back/forward click allocated a brand new gump via `GetResentGump`. After migration, those handlers mutate `_filter`, `_startNumber`, `_comparer`, `_ascending`, or `_display` on the existing gump and call `from.SendGump(this)`, letting the singleton path in `NetStateGumps.Send` swap in the same instance with the new layout. The original list is preserved separately from the per-render filtered/sorted `_displayList`, so refreshes pick up the latest state without losing the source list. All guild gumps deal with per-instance dynamic strings (guild names, member names, war declarations, alliance names), which would defeat `StaticGump<T>` caching per the cliloc rule, so every concrete subclass migrates to `DynamicGump`. `AllianceRosterGump` (in `Misc/Guild.cs`) is a `GuildDiplomacyGump` subclass and inherits the new behavior; its unused override and stored alliance reference were dropped along with the now-obsolete `GetResentGump` abstract. |
