## Summary
Migrates the Old Guild System (pre-AOS guild stones) gumps from the legacy `Gump` class to `DynamicGump`, following the same pattern used for the Quest gump migration in #2416. All concrete gumps now have private constructors gated by static `DisplayTo` entry points (empty-gump rule), and `Singleton => true` is set across the board so reopening a sibling dialog automatically closes the previous one.
**Migrated gumps:**
- `GuildGump` - main guild dialog
- `GuildmasterGump` - guildmaster functions
- `GuildCharterGump` - charter and website display
- `GuildWarGump` - warfare status (kept as player-facing)
- `GuildWarAdminGump` - war menu (retained as player-facing - reachable from `GuildmasterGump`'s WAR button by guildmasters)
- `GuildChangeTypeGump` - Standard/Order/Chaos selection
**Abstract bases:** `GuildListGump` and `GuildMobileListGump` keep their shared list-rendering chrome inside a single concrete `BuildLayout` on the abstract class and expose a `protected abstract void BuildHeader(ref DynamicGumpBuilder builder)` hook for subclasses (replacing the old `Design()` override). This mirrors the abstract-base treatment used for the ML quest base in the quest-gump migration PR.
**Concrete subclasses migrated alongside the abstract bases:**
- `GuildListGump` subclasses: `GuildAcceptWarGump`, `GuildDeclarePeaceGump`, `GuildDeclareWarGump`, `GuildRejectWarGump`, `GuildRescindDeclarationGump`
- `GuildMobileListGump` subclasses: `DeclareFealtyGump`, `GrantGuildTitleGump`, `GuildAdminCandidatesGump`, `GuildCandidatesGump`, `GuildDismissGump`, `GuildRosterGump`
**Cliloc rule:** Every gump bakes per-instance dynamic content (guild names, member names, war declarations, candidate lists), which would defeat `StaticGump<T>` caching. Per the cliloc rule, all are `DynamicGump`.
**External callers updated:** the prompt files (`GuildAbbrvPrompt`, `GuildCharterPrompt`, `GuildDeclareWarPrompt`, `GuildNamePrompt`, `GuildTitlePrompt`, `GuildWebsitePrompt`), `RecruitTarget`, the `Guildstone` item, and the New Guild System `GuildInfoGump`'s Order/Chaos handler all now go through static `DisplayTo` entry points instead of `new XGump(...)`.
## 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.
## Summary
Migrates three legacy `Gump`-based dialogs to the modern builder API:
- **PlayerBBGump** (`Projects/UOContent/Items/Misc/PlayerBulletinBoards.cs`) — `DynamicGump`. The bulletin board renders a different post per page (variable per-instance state), so the layout cannot be cached. Now `Singleton`, with a private constructor and a static `DisplayTo` entry point. Scroll/banish/delete/post-props buttons mutate `_page` and self-refresh via `SendGump(this)` instead of allocating a fresh gump on every click. Prompt-driven flows (post message / set title / post greeting) re-enter through `DisplayTo` after the prompt completes.
- **MessageGump** + **OldMessageGump** (`Projects/UOContent/Items/Skill Items/Fishing/Misc/SOS.cs`) — `StaticGump<T>`. Both render a fixed structure (background + body + button) where only the formatted sextant coordinate string varies per SOS bottle. The cliloc IDs that *appear in the gump packet* are constant (`MessageGump` uses 1018326; `OldMessageGump` uses no `AddHtmlLocalized` at all — its message is pre-formatted into a string before construction), so the layout cache is safe per the cliloc rule. The varying coordinate text is fed through an HTML placeholder via `BuildStrings`. Both gumps are now `Singleton` with private constructors and static `DisplayTo` entry points.
- **ShardPollGump** (`Projects/UOContent/Misc/ShardPoller.cs`) — `DynamicGump`. The gump's structure changes both with the number of poll options (variable loop) and with the `editing` flag (admin sees radios + add-option row + result percentages; players see only radios). The dual-purpose view is preserved as a single `DynamicGump` with the `editing` flag still controlling layout shape — staff path verified to still render the editor with the totals header, vote percentages, and "Create new option" radio. `Closable = false` becomes `builder.SetNoClose()`. Now `Singleton`, with private constructor and a `DisplayTo` that returns the gump instance so `EventSink_Login_Callback` can still call `QueuePoll` on it. The cancel/edit re-issue paths use `SendGump(this)` for self-refresh; the queued login flow uses `DisplayTo` so each queued poll gets its own gump.
External callers (`OnDoubleClick`, `PostPrompt`, `SetTitlePrompt`, `ShardPollPrompt`, `EventSink_Login_Callback`, the Timer-delayed queued poll send) all updated to use the new `DisplayTo` entry points. Legacy `m_X` field naming was already absent in two of the three files; the bulletin board fields kept their `_camelCase` names. `dotnet build Projects/UOContent/UOContent.csproj` reports 0 warnings, 0 errors.
## Summary
Migrates the five-step SoulStone wizard and the TreasureMapChest remove-confirmation dialog from legacy `Gump` to the modern builder API.
Per-gump base type:
- **`SelectSkillGump` -> `DynamicGump`** -- the skill picker iterates the player's skill list and emits one button per non-zero skill, so the layout shape varies per instance.
- **`ConfirmSkillGump` -> `DynamicGump`** -- skill name uses `AosSkillBonuses.GetLabel(...)` which returns dynamic clilocs in the `1044060 + (int)skill` range, plus current/cap skill values rendered as text labels.
- **`ConfirmTransferGump` -> `DynamicGump`** -- same dynamic skill cliloc plus per-instance Base/Cap/Stored values.
- **`ConfirmRemovalGump` -> `StaticGump<ConfirmRemovalGump>`** -- only fixed clilocs (warning text, Continue, Cancel), so the layout caches.
- **`ErrorGump` -> `DynamicGump`** -- title and message clilocs are constructor parameters that vary per call site.
- **`TreasureMapChest.RemoveGump` -> `StaticGump<RemoveGump>`** -- fixed-cliloc confirmation prompt (no item list, despite the name); `Closable=false`/`Disposable=false` are now `builder.SetNoClose()`/`builder.SetNoDispose()`.
All six gumps are now `Singleton => true`, have private constructors, and expose a static `DisplayTo` entry point that validates `from`, `NetState`, and the underlying entity before constructing -- prevents the empty-gump leak. Wizard navigation between steps now goes through `DisplayTo` (e.g. `ConfirmSkillGump.DisplayTo(from, _stone, skill)` from the skill picker, `ErrorGump.DisplayTo(...)` from absorption pre-checks, `SelectSkillGump.DisplayTo(...)` from the "make another selection" button on `ConfirmSkillGump` and from `ErrorGump` bounce-back). Because each gump is Singleton, sending the same type again automatically closes any prior instance instead of stacking; the explicit `gumps.Close<T>()` chain on `OnDoubleClick` is preserved so opening the soulstone still resets any orphaned step from another wizard.
`OnResponse` now uses `in RelayInfo info`. All inline `AddX(...)` calls move to `builder.AddX(...)` inside `BuildLayout`. `Skill.Base.ToString("F1")` etc. are converted to `$"{value:F1}"` interpolation passed to `AddLabel(ReadOnlySpan<char>)`. Skill picker pagination still uses client-side `AddPage` / `GumpButtonType.Page` -- no server-state pagination to migrate.
## Summary
Migrates the Quest system gumps from legacy `Gump` to `DynamicGump` / `StaticGump<T>`.
**Renames** `Engines/ML Quests/Gumps/BaseQuestGump` to **`BaseMLQuestGump`** to
disambiguate from the Core quest abstract (`Engines/Quests/Core/QuestSystem.cs`).
Both abstracts now extend `DynamicGump`.
**Abstract bases**:
- `Server.Engines.Quests.BaseQuestGump` (Core) - now `abstract DynamicGump`. Holds constants and a static `AddHtmlObject(ref DynamicGumpBuilder, ...)` helper. Concrete subclasses each provide their own `BuildLayout`.
- `Server.Engines.MLQuests.Gumps.BaseMLQuestGump` (ML, renamed) - now `abstract DynamicGump` with a `protected abstract BuildContent(ref DynamicGumpBuilder)` hook. The base's `BuildLayout` draws shared chrome (background art, frame, label header) and then invokes `BuildContent`; subclasses use `BuildPage`, `SetTitle`, `RegisterButton`, `SetPageCount`, and content helpers (`AddDescription`, `AddObjectives`, `AddObjectivesProgress`, `AddRewardsPage`, `AddRewards`, `AddConversation`).
**Concrete Core gumps** migrated to `DynamicGump`:
- `QuestCancelGump`, `QuestOfferGump` (Core), `QuestObjectivesGump`, `QuestConversationsGump`, `QuestLogUpdatedGump`, `QuestItemInfoGump`, `SheetMusicOfferGump` (Impresario), `PaintedImageGump` (renamed from `PaintedImage.InternalGump`).
**Concrete ML gumps** migrated to `DynamicGump` (extending `BaseMLQuestGump` or directly):
- `InfoNPCGump`, `QuestConversationGump`, `QuestLogDetailedGump`, `QuestLogGump`, `QuestOfferGump` (ML), `QuestReportBackGump`, `QuestRewardGump`, `QuestCancelConfirmGump`, `RaceChangeConfirmGump`.
**`StaticGump<T>` migrations**:
- `ScrollOfAbraxusGump` (Dark Tides). Its layout is a single hard-coded cliloc (1060116) with no per-instance dynamic content - safe to cache.
**Cliloc rule**: Every other quest dialog bakes per-instance cliloc IDs into its layout (quest titles, NPC names, race-specific prompts, era-conditional progress messages, escort destinations). Per the cliloc rule, baking different cliloc numbers into a cached layout would defeat `StaticGump<T>` caching - so all of these are `DynamicGump`.
**Signature changes** to support the migration:
- `QuestObjective.RenderMessage`/`RenderProgress` now take `ref DynamicGumpBuilder builder` (15 overrides updated across Collector, Solen Matriarch, Ambitious Solen Queen, Study of the Solen Hive, Terrible Hatchlings, The Summoning, Uzeraan Turmoil, Witch Apprentice, Emino's Undertaking).
- ML `BaseObjective.WriteToGump` / `BaseObjectiveInstance.WriteToGump` / `BaseReward.WriteToGump` now take `ref DynamicGumpBuilder` (KillObjective, GainSkillObjective, EscortObjective, CollectObjective, DeliverObjective, BaseReward).
**Empty-gump and `Singleton` rules**: All concrete gumps now have private constructors with static `DisplayTo` entry points that null-check the player NetState before allocation. All gumps that shouldn't stack are `Singleton => true`.
**External callers updated**: `MLQuest.SendOffer`/`OnRefuse`, `MLQuestEntry.SendProgressGump`/`SendRewardGump`/`SendReportBackGump`, `MLQuestSystem.QuestGumpRequest` and `ViewQuestsCommand`, `BoonCollector` (Darius/Nedrick), `SirHelper.OnDoubleClick` (no longer caches a single shared `InfoNPCGump` instance - `DisplayTo` constructs one per click and the gump's `Singleton => true` handles deduplication), `RaceChangeDeed.OnDoubleClick`, `PaintedImage.OnDoubleClick`, `ScrollOfAbraxus.OnDoubleClick`, `Impresario.OnTalk`, and `PlayerMobile`'s `BaseQuestGump` alias is now `BaseMLQuestGump`.
**Concrete subclasses found beyond the listed entry points**: `SheetMusicOfferGump` (in Impresario.cs), `PaintedImageGump` (was `PaintedImage.InternalGump`), `QuestObjectivesGump`, `QuestConversationsGump`, `QuestLogUpdatedGump`, `QuestItemInfoGump` (the Core base has these embedded across `QuestSystem.cs`/`QuestObjective.cs`/`QuestConversation.cs`/`QuestItemInfo.cs`).
**Code-standards cleanup**: Renamed legacy `m_X` private fields to `_x` in rewritten files; braces on all control flow.
## Summary
Migrates five legacy `Gump`-derived UI dialogs in the NPC and Skill domains to the modern `DynamicGump` builder pipeline. All five gumps were chosen as `DynamicGump` rather than `StaticGump<T>` because their layout shape varies per instance, and several of them carry per-instance localization numbers (cliloc IDs) that the static cache cannot bake (see CLAUDE.md gump-system rule and `dev-docs/gump-system.md`).
Per-gump rationale:
- **`TownCrierGump` (`Mobiles/Townfolk/TownCrier.cs`)** - DynamicGump. Announcement count varies, expiration text is rebuilt per render via `ValueStringBuilder`, and one button per entry is emitted in a loop.
- **`ClaimListGump` (`Mobiles/Vendors/NPC/AnimalTrainer.cs`)** - DynamicGump. The pet list and resulting background/alpha-region heights vary per stabling player.
- **`AnimalLoreGump` (`Skills/AnimalLore.cs`)** - DynamicGump. Page count itself varies (3 pages pre-AOS, 5 pages on AOS) and several `AddHtmlLocalized` calls use cliloc IDs computed from per-creature data (loyalty rating `1049595 + c.Loyalty / 10`, food preference, pack instinct), which violates the StaticGump cliloc-bake rule.
- **`DisguiseGump` (`Items/Skill Items/Thief/DisguiseKit.cs`)** - DynamicGump. Page count and entry order shift on `from.Female`, `Body.IsFemale`, and `startAtHair`.
- **`CommentsGump` (`Gumps/CommentsGump.cs`)** - DynamicGump. Comment list and pagination depend on `Account.Comments` size; the title label encodes the variable account username string.
All five are now `Singleton => true`, have `private` constructors, and expose static `DisplayTo(...)` entry points that validate prerequisites before constructing - guaranteeing no empty gumps (CLAUDE.md Sec.13). All internal refresh paths (prompts, `OnDoubleClick`, command handlers, target callbacks) were updated to call `DisplayTo` rather than `new XGump(...)`. Legacy `m_`-prefixed fields renamed to `_camelCase` (CLAUDE.md Sec.12), and `DisguiseEntry`'s `m_`-prefixed public readonly fields converted to PascalCase auto-properties. `OnResponse` signatures updated to `in RelayInfo info`. No external callers needed updating - all `new XGump(...)` sites lived inside the same files.
## 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.
## Summary
Migrates the three player-facing travel/moongate gumps from legacy `Gump` to the modern `DynamicGump` system.
- `GoGump` (Gumps/Go/GoGump.cs) → `DynamicGump`. The category-tree layout's row count varies with the current `GoCategory`'s child count and pagination. Refreshes via `SendGump(this)` after mutating `_node`/`_page` instead of allocating a new instance per nav/page click.
- `MoongateGump` (Items/Misc/PublicMoongate.cs) → `DynamicGump`. The destination tab strip and per-map pages are gated by ruleset (sigil bearer, murderer, faction facet) and expansion/young flag, plus the configured map selection. The set of pages and the active-map swap make the layout shape per-instance.
- `MoongateConfirmGump` (Items/Skill Items/Magical/Misc/Moongate.cs) → `DynamicGump`. Per the **dynamic-cliloc rule**, the gump bakes one of two different cliloc numbers (1062050 Felucca-warning vs 1062049 generic confirm) and selects between an AOS and pre-AOS layout shape — both characteristics force `DynamicGump` rather than `StaticGump<T>` because cached layout bytes would otherwise lock in the wrong cliloc/shape.
All three now use a `private` constructor with a `public static DisplayTo(...)` entry point that validates prerequisites before any gump is allocated (empty-gump rule, CLAUDE.md §13). All are `Singleton` and use `SendGump(this)` self-refresh on internal navigation. Updated callers: `PublicMoongate.UseGate` and `Moongate.BeginConfirmation` now call `DisplayTo(...)`.
## Summary
Second PR in the player-facing legacy gump migration. Converts the four Plants system gumps:
- `MainPlantGump`, `ReproductionGump`, `EmptyTheBowlGump` → `DynamicGump`. Layout varies by plant status, growth stage, health, and pollination/resource availability — cannot use cached `StaticGump<T>`.
- `SetToDecorativeGump` → `StaticGump<SetToDecorativeGump>`. Pure confirmation dialog with no per-instance variation.
All four:
- `Singleton => true` (auto-replace previous plant gump on re-open instead of stacking)
- Constructor `private`; entry is static `DisplayTo(Mobile, PlantItem)` per the empty-gump rule (CLAUDE.md §13)
- `OnResponse` self-refresh paths converted from `from.SendGump(new XGump(_plant))` to `from.SendGump(this)` — saves an allocation on every help/info button click and on every "gather resources/seeds/pollen" action
- Helper draw methods take `ref DynamicGumpBuilder builder` instead of mutating instance state
- Renamed legacy `m_Plant` to `_plant` per CLAUDE.md §12
Updated external callers to use the new entry points:
- `PlantItem.OnDoubleClick` → `MainPlantGump.DisplayTo(from, this)`
- `PlantPourTarget.OnTargetFinish` → `MainPlantGump.DisplayTo(from, m_Plant)` (also drops the now-redundant legacy `singleton: true` flag — `Singleton` property handles it)
- `PollinateTarget.OnTargetFinish` → `ReproductionGump.DisplayTo(from, m_Plant)`
## Summary
First PR in a multi-PR migration of player-facing legacy `Gump` subclasses to the modern `DynamicGump` / `StaticGump<T>` system. Plan covers ~95 files across ~14 PRs by system; this PR is the foundation (smallest, isolated, no cross-refs).
- `VirtueGump` → `DynamicGump`: per-instance virtue hues from `GetHueFor()` and the conditional self/other button block prevent layout caching.
- `VirtueStatusGump` → `StaticGump<VirtueStatusGump>`: layout is identical for every player; only used as a navigation hub.
- `VirtueInfoGump` → `DynamicGump`: dynamic cliloc IDs (`1051000 + (int)virtue`, the description cliloc, and the conditional `1052055`/`1052052` footer) cannot be cached by `StaticGump<T>` — cliloc *numbers* are baked into layout bytes, only HTML/label *text* can be deferred to placeholders.
All three:
- `Singleton => true` (replaces previous instance instead of stacking)
- Constructors made `private`; entry points are static (`RequestVirtueGump`, `DisplayTo`) per the empty-gump rule (CLAUDE.md §13)
- `OnResponse` updated to `in RelayInfo info` modern signature
- `VirtueInfoGump` self-refresh button now uses `_beholder.SendGump(this)` instead of allocating a new instance
- Removed the unused `VirtueGumpItem : GumpImage` nested class — replaced with direct `builder.AddImage(...)` calls; preserves the legacy `class=VirtueGumpItem` attribute for packet parity
The special-cased TypeID for VirtueGump (`BaseGump.cs:86`) is preserved because the type's full name (`Server.Engines.Virtues.VirtueGump`) is unchanged.
## Summary
Removes per-call heap allocations from `Container`'s consume / find / group hot paths and from `BaseCreature.OnDeath`'s fame/karma tracking. The headline wins: kill the `List<List<Item>>` + `Item[][]` + `int[]` grouping bridges in `ConsumeTotal*` / `ConsumeTotalGrouped*` / `GetBestGroupAmount*`, and kill the per-call `Predicate<Item>` allocations in `FindItemsByType(Type)` / `FindItemsByType(Type[])`.
### `Container.cs`
- `ConsumeTotal`, `ConsumeTotalGrouped`, `GetBestGroupAmount` now share four streaming helpers (`HasAmount`, `TryFindGroupMeetingAmount`, `BestGroupTotal`, `ConsumeSlice`) backed by `PooledRefList` instead of allocating per-group lists and jagged arrays. Two-phase validate-then-consume pattern preserved — all-or-nothing semantics for spell reagents, vendor pay, and crafting still hold.
- `(Type)` / `(Type[])` / `(Type[][])` overload trios collapsed to single `ReadOnlySpan<Type>` + `ReadOnlySpan<int>` implementations. Implicit `T[] → ReadOnlySpan<T>` conversion means UOContent callers compile unchanged.
- Unused overloads deleted: `ConsumeTotalGrouped(Type)`, `ConsumeTotalGrouped(Type[][])`, `GetBestGroupAmount(Type)`, `GetBestGroupAmount(Type[][])`, plus the never-called `TryDropItems` hook and its private `ItemStackEntry` struct.
- Fixes a `PooledRefList` leak in `GetBestGroupAmount(Type[], …)` (missing `using`).
- `m_ContainerData` / `m_Items` / `m_TotalGold` / `m_TotalItems` / `m_TotalWeight` / `ContainerData.m_Table` / `ContainerData.logger` renamed to the underscored convention. `m_Items` cross-file rename for the Container-side references in `Item.cs`; `Item.CompactInfo.m_Items` deliberately left alone (separate effort).
- `CheckHold` parent walk simplified; trivial dispatch methods (`CheckHold` overloads, `OnItemAdded`, `OnItemRemoved`, `OnStackAttempt`) get `[MethodImpl(AggressiveInlining)]`; `Destroy` and `DisplayTo` cache `Items` outside the loop; dead comments removed.
### `Item.Enumerable.cs`
- `FindItemsByType(Type)` previously allocated a `Predicate<Item>` per call (method-group conversion). `FindItemsByType(Type[])` allocated a closure capturing `types`. Both now construct the enumerator with a `Type` / `ReadOnlySpan<Type>` field directly, no delegate.
- `FindItemsByTypeEnumerator<T>` gains two constructors plus a `Matches(T)` helper that picks the right filter inline. Constructor chaining via a private 2-arg seed constructor incidentally fixes a pre-existing bug where `PooledRefQueue` was always rented at capacity 0 because `_recurse` hadn't been assigned yet.
- `(Type[])` overload of `FindItemsByType` becomes `(ReadOnlySpan<Type>)`.
- `EnumerateItemsByType(Type)` / `EnumerateItemsByType(ReadOnlySpan<Type>)` / `ListItemsByType(Type)` / `ListItemsByType(ReadOnlySpan<Type>)` simplified to delegate to the new alloc-free overloads instead of filtering manually.
### `Utility.cs`
- `InTypeList<T>(this T, Type[])` and `InTypeList(this Type, Type[])` switched to `ReadOnlySpan<Type>`.
### `BaseCreature.cs`
- `OnDeath` per-death `List<Mobile>` / `List<int>` / `List<int>` for fame/karma tracking switched to `PooledRefList`.
## Summary
Overhauls the fame and karma system to be more era-accurate, based on original design documents and publish notes.
### Karma on player kill → karma on murder report
- Removes karma gain/loss on player kill (was immediate on death)
- Karma is now set to `Kills * -1000` on murder **report** instead
- Fame on player kill now uses the same formula as monster kills (`Fame / 100`)
This karma loss on murder report behaviour was tested on both the demo and live servers, behaviour was matching in terms of karma loss on report. Official UO servers karma loss AMOUNT match with my memory of T2A/UOR with one caveat - it's doubled on live servers (-2000 * kill count). I'm not sure when this changed and this behaviour has always had very poor and incorrect documentation, even 10-20 years ago. I was obsessed with the dread lord title on OSI and the only way I knew how to get it was reach 10 kills then macro them off. Even in publish 16 (when "The Murderer" title was removed) it still required 10 kills. Maybe it changed to -2000*Kills in AOS - that's where I've put the era gating diff.
### Era gates
- **Karma lock** (ankh toggle + auto-lock on negative karma) gated to `Core.UOTD && !Core.AOS` — [didn't exist before Jan 28, 2001](https://web.archive.org/web/20010128092700/http://update.uo.com/design_300.html)
- **Felucca fame/karma +30% bonus** gated to `Core.LBR` — [added in Publish 16, July 2002](https://uo.com/wiki/ultima-online-wiki/technical/previous-publishes/2002-2/publish-16-part-2-5-23rd-july/)
- **Fame/karma splitting** among damage dealers gated to `Core.UOR` — pre-UOR awards go to last hit only
### Skill karma penalties
- **Provocation** on innocent NPC: NPC says cliloc 501591, karma loss (floor -7500)
- **Stealing** attempt: karma loss on every attempt (floor -5000). Stealing did not cause karma loss at all before!
- **Summon Daemon**: karma loss on successful cast (floor -7000)
- **Corpse carving** (human): -70 for innocent corpses (floor -7000), -20 for freely-aggressable (floor -2000)
- **Bounty head turn-in**: karma gain capped at 2000 (was awarding flat +2000)
### Beneficial action karma

### Refactoring
- Extracted `Titles.ComputeKillAwards(killed, map)` shared by player kill and creature kill paths
- Extracted `Titles.SetKarma(m, value, message)` for direct karma assignment (used by murder report)
- Extracted `SendKarmaMessage` and `CheckKarmaLock` helpers from `AwardKarma`
## Summary
- Fixes pets falling behind mounted masters in AOS+ by setting `CurrentSpeed = 0.1` when following master
- Fixes AI timer permanently stopping when `Obey()`/`Think()` returns `false` for transient conditions
- Fixes controlled pets losing AI in inactive sectors (pet follows owner across sector boundary, sector deactivates, AI dies)
- Adds defense-in-depth: AI timer restarts on pet resurrection and order changes
## AI Timer Permanent Stop (Bug Fix)
`AITimer.OnTick()` called `Stop()` when `Obey()` or `Think()` returned `false`. By that point, `ShouldStop()` had already validated the creature is alive, on a valid map, and in an active sector — so any `false` return was a **transient** condition, not terminal. The timer stopped permanently with no mechanism to restart it.
**Scenarios that triggered permanent AI death:**
- Dead bonded pet with attack order (`DoOrderAttack` returned `false` for `IsDeadPet`)
- Failed pet transfer — loyalty refusal, combat, disconnected player, or pending trade (`DoOrderTransfer` returned `false` for 5 different transient conditions)
- Unknown `OrderType` or `ActionType` (defensive defaults)
**Fixes:**
- Removed `Stop()` from the `Obey()`/`Think()` failure path — timer skips the tick and fires again next interval
- Changed `DoOrderAttack()` and all five `DoOrderTransfer()` failure paths to return `true` (correct semantics: these are recoverable states, not "stop AI forever" signals)
- Added `Activate()` call in `ResurrectPet()` — ensures dead bonded pets have AI running after resurrection
- Added `Activate()` call in `OnCurrentOrderChanged()` — self-heals timer if any voice command is issued to a pet with a stopped timer
## Controlled Pet Sector Deactivation (Bug Fix)
`ShouldStop()` stopped the AI timer for **all** `PlayerRangeSensitive` creatures in inactive sectors, including controlled pets. But `Deactivate()` intentionally exempted controlled pets. The exemption was dead code — `ShouldStop()` bypassed it.
This matters when a pet follows its owner across a sector boundary: the owner enters the next sector (active), the pet's old sector deactivates (no more players), and the pet's AI dies. The pet stops following and stands there until the player backtracks far enough to reactivate the sector.
**Fix:** Added `Controlled` check to `ShouldStop()` to match `Deactivate()`. Controlled pets now keep their AI running in inactive sectors. The overhead is negligible — controlled pets are bounded by follower slots.
## Movement Speed Simplification
- Simplifies `AITimer` to use `CurrentSpeed` directly as the tick interval (in seconds), removing the complex multiplier/floor logic in `GetBaseInterval`
- Refactors `DoMoveImpl` speed assignment into explicit if/else for clarity
- AOS+ pets following master use `CurrentSpeed = 0.1` (100ms), matching `RunMountDelay`
## Files Changed
- `AITimer.cs` — removed `Stop()` on Obey/Think failure, added `Controlled` exemption to `ShouldStop()`, simplified interval logic
- `BaseAI.cs` — renamed `_timer` to `AITimer` (public), simplified `Deactivate()`, fixed `ReturnToHome` to use `Activate()`
- `PetOrders.cs` — `DoOrderAttack` and `DoOrderTransfer` return `true` for transient failures
- `PetOrderHandlers.cs` — `OnCurrentOrderChanged()` calls `Activate()` to self-heal stopped timers
- `BaseCreature.cs` — `ResurrectPet()` calls `Activate()`, fixed `GoHome_Callback` PlayerRangeSensitive check
- `AIMovement.cs` — refactored speed assignment, AOS+ follow-master speed fix
## Summary
Replaces the basic `publish.cmd`/`publish.sh` scripts with an interactive **BuildTool** — a C# console app using [Spectre.Console](https://spectreconsole.net/) that guides users through publishing, prerequisite checking, and cross-compilation.
### Why
The community found the existing publish scripts unhelpful for newcomers. They worked but didn't walk users through the process, didn't check prerequisites, and provided no feedback when things went wrong.
### What's New
**Interactive BuildTool** (`Projects/BuildTool/`)
- NativeAOT-compiled C# console app with true-color ASCII logo and ModernUO brand gold/silver palette
- Guided publish wizard with step-by-step back navigation (Ctrl+C or menu "Back" to go to previous step)
- Prerequisite checking: .NET SDK version, VC++ Redistributable (Windows), native libraries (Linux/macOS)
- .NET SDK auto-install offer via Microsoft's official install scripts
- Platform detection: Windows 10 vs 11 (build number), macOS codenames, Linux distro + kernel version
- Cross-compilation support: skips native library checks, shows target prerequisites after build
- Non-interactive mode for CI: `--config Release --skip-prereqs`
- Backward-compatible positional args: `publish.cmd release win x64` still works
**Shell Wrappers** (`publish.cmd`, `publish.ps1`, `publish.sh`)
- Try native BuildTool binary first (downloaded from GitHub Releases)
- Fall back to `dotnet run --project Projects/BuildTool` if unavailable
- SDK bootstrapping: offer to install .NET if not found
**CI/CD Updates**
- Build/test workflows target `Projects/Application/Application.csproj` instead of the solution (excludes BuildTool and test projects from publish)
- New `build-tool-release.yml` workflow builds NativeAOT binaries for win-x64, win-arm64, osx-arm64, linux-x64, linux-arm64
- Minimum SDK bumped to 10.0.201 (required for Serialization Generator 2.14.3 / Roslyn 5.3.0)
**Other Changes**
- Solution converted from `.sln` to `.slnx`
- Updated README with interactive mode instructions and deployment guidance

## Summary
- **Add a self-referencing `InterpolationHandler` to `ValueStringBuilder`** that writes directly into the builder's buffer — zero intermediate allocation, works with `stackalloc`-backed builders
- **Replace all `System.Text.StringBuilder` usage** across the codebase with `ValueStringBuilder`
- **Convert `ValueStringBuilder.Create()` to `stackalloc`** at 10 sites where output length is provably bounded
- **Convert manual `Dispose()` to `using var`** where possible, and hoist loop-scoped builders outside loops with `Reset()`
- **Convert verbose `Append()` chains to `Append($"...")`** interpolation for readability
- **Add comprehensive documentation** for string handling patterns
## InterpolationHandler Design
`ValueStringBuilder` is a `ref struct`, which creates challenges for C#'s interpolated string handler pattern:
- **`ref` fields to ref structs are not allowed** (CS9050)
- **`[InterpolatedStringHandlerArgument("")]` passes struct receivers by value**, not by ref
- **`ISelfInterpolatedStringHandler` requires boxing** ref structs into interface fields
**Solution: Copy-and-reconcile pattern.** The handler receives a value copy of the builder. The copy shares the same underlying `char` buffer (`Span` points to the same `stackalloc`/pooled memory), so writes go to the original buffer. `Append()` reconciles by `this = handler._builder`, updating `_length` and any buffer references changed by `Grow()`.
This is safe because:
- The game loop is single-threaded — no concurrent access between handler construction and reconciliation
- If `Grow()` occurs in the copy, the original's stale buffer isn't accessed until `Append()` replaces it
- `Dispose()` correctly returns the reconciled buffer to the pool
## Changes by Category
### ValueStringBuilder (`Projects/Server/Buffers/ValueStringBuilder.cs`)
- Added nested `InterpolationHandler` ref struct with copy-and-reconcile pattern
- Added `Append([InterpolatedStringHandlerArgument("")] scoped ref InterpolationHandler)` method
- Removed `RawInterpolatedStringHandler` overloads (new handler replaces them)
- All `AppendFormatted` overloads delegate to existing `Append` methods (no code duplication)
- Alignment support via direct private field access (nested type privilege)
### StringBuilder → ValueStringBuilder (15 files)
Replaced all `new StringBuilder()` with `ValueStringBuilder.Create()` or `stackalloc`:
- ConPVP games: KingOfTheHill, DoubleDom, CTF, BombingRun, TourneyMatch
- ConPVP infrastructure: Tournament, Participant, TourneyParticipant
- ConPVP gumps: ArenaGump, TournamentBracketGump, AcceptTeamGump, ConfirmSignupGump
- Commands: Handlers, Logging, Add
- Other: TownCrier, SpeechLogGump, TestCenter
Key patterns:
- `sb = new StringBuilder()` reassignment → `sb.Reset()`
- `sb.AppendFormat("{0:N0}", value)` → `sb.Append($"{value:N0}")`
- `sb.Append(x).Append(y)` chains → separate statements (VSB returns void)
### Create() → stackalloc (10 files)
Converted heap-allocated builders to stackalloc where output is bounded:
- ClientVersion (32), MapSelection (160), HouseRaffleStone (48)
- HolySense (96), UnholySense (96), ClientVerification (192)
- AcceptTeamGump (64), ConfirmSignupGump (64)
- BaseWeapon (160), BaseArmor (128)
### Loop optimizations (2 files)
Hoisted `ValueStringBuilder` creation outside loops with `Reset()` per iteration:
- TourneyMatch.cs: `using var` inside for loop → stackalloc before loop
- ArenaGump.cs: `Create()` + `Dispose()` per iteration → stackalloc before loop
### Append chain → interpolation (5 files)
Converted multi-line `Append()` chains to `Append($"...")`:
- BountyMessage.cs: title switch (6 cases), paragraph (15→1 Append), description lines, closing
- AcceptTeamGump, ConfirmSignupGump, TournamentBracketGump: tournament type strings
- AdminGump: comment/tag formatting in loops
### Documentation
- `dev-docs/string-handling.md`: Full reference — construction, interpolation, disposal, decision guide
- `dev-docs/claude-skills/modernuo-string-handling.md`: Claude skill with quick reference
- `CLAUDE.md`: Added rule 17 (no StringBuilder), dev-docs table entry, skills table entry
- `dev-docs/code-standards.md`: Updated memory management section
## Test Plan
- [x] `dotnet build` — 0 errors, 0 warnings
- [x] `dotnet test` — 940/940 tests pass
- [x] 28 ValueStringBuilder tests covering all reconciliation scenarios:
- Stackalloc no-grow, stackalloc with grow (→pool transition)
- Heap no-grow, heap with grow, heap double grow
- Pre-existing content with and without grow
- Sequential multiple `Append($"...")` calls
- Mixed plain + interpolated Append
- Empty interpolation, literal-only, format specifiers
- Null string holes, ISpanFormattable types
- Dispose after stackalloc→pool grow

## Setup
* Setup as part of decorate when bounty system is enabled
* Several bounty board locations with a WarriorGuard spawner in front of the board. Guard spawns and idles around 5 range.
## Tests
### ReportBountyMurdererGump
* Follows same behaviour as ReportMurdererGump
* Extracted common logic
* Didn't use staticgump due to several dynamic parts including input
* Optional bounty with validation >0 and <bankbox.total
* Murder report is honored either way
### Bounty boards
* Open bounty board with many bounties, no bounties
* Keep a bounty board open, invalidate a bounty by turning in the head, then try to click on the post of the now invalid post. As expected: does nothing
* Bounty messages use the last murder time as their post date and expire in 14 days
* Bounty boards/messages are not reliant on serialization; they use serialized fields from MurderContext to build messages when clicked.
* Bounty messages use synthetic serials so they do not have to persist bounty messages as items. They are constructed and sent as raw packets when needed.
* Players only appear on the bounty board if they are a murderer (though a non-murderer can technically still have a bounty if they decayed kills)
* Tested skin/hair color descriptions vs a dozen spot checks
### Head turn in behaviour
* Guard accepts head
* Bounty -> gives bounty
* No bounty -> generic response
* Expired head (24h) -> generic response
NOTE: CUO "latest" has a bug with bounty/bulletinmessages that causes overflow outside of the container. It has nothing to do with this PR. It is fixed here in CUO https://github.com/ClassicUO/ClassicUO/pull/1871
# Murderer title
Bounty system and "murderer" title eliminated in [pub16](https://uo.com/wiki/ultima-online-wiki/technical/previous-publishes/2002-2/publish-16-part-2-5-23rd-july/). So UO:LBR and before had bounties and murderer title.
# Pre-T2A caveat
There were differences in pre-T2A, but this cannot be currently implemented because we do not have any pre-T2A systems in general, so at least for now, behavior is consistent with later eras. Pre-T2A was a whole other ballgame, but the bounty system still worked similarly.
## Summary
Implements T2A-accurate mechanics for the three defensive spells based on UO98 demo scripts. Pre-UOR (`!Core.UOR`) triggers the new behavior; UOR and AOS paths are unchanged.
- **Reactive Armor**: percentage-based melee damage reflection (10-35% based on target Magery), targeted, timed (25-75s). Guards exempt, ranged attacks beyond 1 tile unaffected. Reflected damage is sourceless.
- **Protection**: temporary AC bonus (casterMagery/10, 1-10 AR) via VirtualArmorMod, targeted, timed (12-120s). Shared table with Arch Protection — only one protection buff per mobile.
- **Magic Reflect**: single-use spell reflection using MagicDamageAbsorb as a flag. No timer, no DefensiveSpell lock. Consumed on first reflected spell.
- **Arch Protection**: T2A path applies Protection via shared table with area sound (0x1F7 vs 0x1ED).
- No DefensiveSpell mutual exclusion for T2A — all three spells operate independently.
## Test plan
- [x] Set expansion to T2A
- [x] Cast Reactive Armor on self → verify particles (0x376A) and sound (0x1F2)
- [x] Get hit in melee → verify attacker takes reflected damage with spark effect and sound
- [x] Get hit by ranged weapon from > 1 tile → verify no reflection
- [x] Wait for RA to expire → verify effect ends silently
- [x] Cast RA on target that already has it → verify "This spell is already in effect"
- [x] Cast Protection on another player → verify particles (0x375A) and sound (0x1ED)
- [x] Check target's AR → verify it increased by casterMagery/10
- [x] Wait for Protection to expire → verify AR returns to normal
- [x] Cast Protection on self, then cast Protection on another player → verify both succeed
- [x] Cast Arch Protection on ground near allies → verify each gets AR bonus with sound 0x1F7
- [x] Cast Arch Protection near a target already protected → verify that target is skipped
- [x] Cast Magic Reflect on self → verify particles (0x375A) and sound (0x1E9)
- [x] Have an enemy cast a harmful spell at you → verify spell reflects back, effect consumed
- [x] Cast Magic Reflect again → verify it can be recast after consumption
- [x] Cast Magic Reflect when already active → verify "This spell is already in effect"
- [x] Verify all three spells can be active simultaneously on the same mobile
- [x] Switch expansion to UOR → verify existing UOR behavior unchanged
- [x] Switch expansion to AOS → verify existing AOS behavior unchanged
## Summary
- Refactors the poison system to separate `Index` (globally unique ID) from `Level` (tier within a family), enabling multiple poison families (Standard, Darkglow, Parasitic) to coexist without collisions
- Implements Darkglow and Parasitic poison special effects from Mondain's Legacy: Darkglow boosts damage by 10% when attacker is ranged, Parasitic heals the attacker for damage dealt in melee range
- Fixes several bugs: `Register()` crashing on duplicate `Level` values across families, `IncreaseLevel()` crossing family boundaries, `InfectiousStrike` and `NinjaWeapons` stripping poison family via level-based lookups, and `ArchCure`/`CleansingWinds` using raw `Level + 1` instead of `IncreaseLevel()`
## Changes
**`Projects/Server/Poison.cs`** — Adds `PoisonFamily` enum and abstract `Family` property. Adds `Index` as unique identifier. Fixes `Register()` to check `Index` uniqueness (not `Level`) and validate the new poison's name (not the existing one's). Fixes `IncreaseLevel()` to use `Index + 1`, naturally respecting family boundaries via Index gaps. Replaces linear name lookup with `Dictionary`-based `PoisonsByName`.
**`Projects/UOContent/Misc/Poison.cs`** — Adds `family` parameter to `PoisonImpl`. Implements Darkglow effect (10% damage boost when `From` >1 tile, cliloc 1072850) and Parasitic effect (heals `From` for damage dealt within 1 tile, cliloc 1060203) in `PoisonTimer.OnTick()`. Renames `m_` fields to `_` convention.
**`Projects/UOContent/Misc/PoisonKinds.cs`** — New file. Moves poison registration out of `PoisonImpl` into `PoisonKinds.Configure()`. Adds `PoisonFamily` to Darkglow/Parasitic registrations. Provides extension properties (`Lesser`, `Deadly`, `LesserDarkglow`, etc.), `GetPoison(int level)` (standard-only), `GetPoisonByFamilyAndLevel()`, and `IsDarkglow`/`IsParasitic` instance helpers.
**`Projects/UOContent/Items/Weapons/Abilities/InfectiousStrike.cs`** — Family-aware poison scaling: Darkglow caps at Deadly (Poisoning/33.3), Parasitic caps at Lethal (Poisoning/25), Standard unchanged. Level bump uses `IncreaseLevel()` with family boundary check.
**`Projects/UOContent/Items/Skill Items/Ninjitsu/NinjaWeapons.cs`** — EvilOmen level bump uses `Poison.IncreaseLevel()` instead of `Poison.GetPoison(Level + 1)`.
**`Projects/UOContent/Spells/Fourth/ArchCure.cs`** and **`CleansingWindsSpell.cs`** — Replace `poison.Level + 1` with `Poison.IncreaseLevel(poison).Level` for family-safe cure chance calculation.
**`Projects/Server/Serialization/SerializationExtensions.cs`** — Serializes/deserializes `Index` instead of `Level`.
**`DarkglowPotion.cs`** / **`ParasiticPotion.cs`** — Point to actual Darkglow/Parasitic poisons instead of placeholder `Greater`.
**`PotionKeg.cs`** / **`BasePotion.cs`** — Adds Darkglow, Parasitic, Invisibility, and FlintsPungentBrew to `PotionEffect` enum and keg label support.
## Test plan
- [ ] `dotnet build` compiles cleanly (verified, 0 warnings 0 errors)
- [ ] Verify `PoisonKinds.Configure()` registers all poisons without throwing (Register bug fix)
- [ ] Standard poison behavior unchanged — PoisonField, PoisonSpell, SerpentArrow, SavageShaman, TrappableContainer all use `GetPoison(int level)` which now correctly filters to Standard family
- [ ] Darkglow: poison tick deals +10% damage when attacker is >1 tile away, sends "Darkglow poison increases your damage!" message
- [ ] Parasitic: poison tick heals attacker for damage dealt when within 1 tile, sends heal message
- [ ] InfectiousStrike preserves poison family and respects family-specific skill scaling
- [ ] EvilOmen + NinjaWeapons level bump stays within poison family
- [ ] ArchCure/CleansingWinds cure chance calculations work correctly across all poison families
- [ ] Serialization round-trips correctly using Index
## Summary
- Adds the Endless Decanter of Water (introduced in Publish 66.2 / SA era)
- Players throw a full Pitcher of Water at a Water Elemental for a 10% chance to receive the decanter; the pitcher is always destroyed on impact
- Each Water Elemental can only yield one decanter; the state is persisted and previously saved elementals are migrated to the new serialization version
- The decanter auto-refills from a linked water trough when the owner empties it within 10 tiles of the stored trough location
- Linking stores a Point3D + Map snapshot, supporting both static tile troughs and addon troughs
- The decanter is blessed and displays Linked/Unlinked status in its tooltip
## Summary
- **Timer-aware idle sleep**: Exposes `Timer.MillisecondsUntilNextTick()` to calculate remaining ms until the next timer wheel tick (0–8ms). The game loop sleeps for that duration minus a 1ms safety margin, instead of spinning at 100% CPU.
- **I/O completion wakeup**: Replaces `Thread.Sleep` with `NetState.WaitForCompletion()`, which uses platform-native completion notification (RIO `RIONotify` on Windows, `eventfd` on Linux, `kevent` timeout on macOS) to wake immediately when network data arrives during sleep.
- **Always-on**: Removes the debug-only `core.enableIdleCPU` config gate. The sleep is self-regulating — under load, `MillisecondsUntilNextTick` returns 0 so no sleep occurs (zero overhead). On idle, CPU drops from ~100% to ~1%.
- **CPS calculation cleanup**: Replaces the 128-element ring buffer with an EMA (exponential moving average) for `CyclesPerSecond`/`AverageCPS` — fewer allocations, no LINQ `.Average()` call each sample.
- **IORingGroup 1.0.6**: Adds `WaitForCompletion(int timeoutMs)` to the `IIORingGroup` interface with platform implementations:
- **Windows**: `RIONotify` arms the CQ event, `WaitForSingleObject` with timeout
- **Linux**: `eventfd` registered with io_uring, `poll()` with timeout
- **macOS**: `kevent()` with timeout
## Test plan
- [ ] Build succeeds on all platforms (`dotnet build`)
- [ ] Empty server: verify CPU usage drops from ~100% to ~1% idle
- [ ] Loaded server: verify no added latency — `MillisecondsUntilNextTick` returns 0 when timers are firing, sleep is skipped
- [ ] Connect a client during idle — verify connection accepted within one timer tick (~8ms)
- [ ] Verify `[admin` gump shows reasonable CPS values (EMA convergence)
## Summary
Fixes three bugs in `GuardedRegion.CallGuards`:
- **Operator precedence bug**: The condition `!m.Region.IsPartOf(this) && !m_GuardCandidates.ContainsKey(m)`
was inverted from intent. Replaced with explicit split: dictionary members are targeted regardless of
region; permanent candidates (reds/AlwaysMurderer) must be inside the region.
- **Premature `break`**: Only the first guard candidate was ever processed per "guards" call.
Removed the `break` so all valid candidates in range get a guard spawned.
- **Misleading message for permanent reds**: "Guards can no longer be called on you." (502276)
was sent to permanent reds, but guards can *always* be called on them. Now only sent to
temporary criminals whose guard window is actually consumed.
Also extracts `IsAlwaysGuardCandidate()` helper and simplifies `IsGuardCandidate()`.
## Edge cases verified (by analysis)
- **Multiple players call guards on same red**: `BaseGuard.Spawn` dedup (scans 15 tiles for
existing guard with same `Focus`) prevents duplicate guards. Message suppression eliminates spam.
- **Red fights spawned guard → criminal → guards called again**: Same dedup prevents infinite
guard spawns. Existing guard already has `Focus == red`.
## Test plan
- [ ] Temporary criminal in guarded region → guard spawns, receives "Guards can no longer be called on you."
- [ ] Permanent red (5+ kills) in guarded region → guard spawns, does NOT receive the message
- [ ] Multiple players call "guards" on same red → only 1 guard spawns
- [ ] Criminal outside region but in dictionary → still targeted by guards call from inside region
- [ ] Red outside guarded region → NOT targeted by guards call (must be inside region)
