+# Веб-клиент: spike KNI и решение A/B
+
+Дата: 2026-06-12. Спайк живёт в `spikes/KniWeb` (вне `LittleSim.sln`).
+
+## Вопрос
+
+Путь A — «MonoGame в браузере» через [KNI](https://github.com/kniEngine/kni)
+(форк MonoGame с платформой Blazor WebAssembly/WebGL, те же неймспейсы
+`Microsoft.Xna.Framework.*`). Путь B — тонкий веб-клиент без MonoGame
+(TypeScript/PixiJS поверх сетевой репликации). Спайк проверял минимальную
+жизнеспособность пути A: **ядро движка + Friflo + WebGL-спрайт в браузере**.
+
+## Что сделано
+
+`dotnet new kni-blazor-gl` (пакет шаблонов `nkast.Kni.Templates`, KNI 4.2.9001,
+net8.0) + ProjectReference на `engine/src/MrGameEng.Core` + мини-хост в духе
+`GameHost` поверх KNI `Game`. Сцена: 300 сущностей в Friflo `EntityStore`,
+`QuerySystem` двигает их в Update-фазе (отскок от краёв, seed 42), Draw-фаза
+рисует через KNI `SpriteBatch` (WebGL).
+
+## Результат — путь A жизнеспособен
+
+- **`MrGameEng.Core` работает в Blazor WASM без изменений**: `EngineContext`,
+  `GameClock`, `Scene`/`SceneManager`, тайминг переходов — всё ядро завелось
+  как есть (заслуга расслоения Core/Host: в ядре нет ни MonoGame, ни платформы).
+- **Friflo.Engine.ECS 3.6 работает в wasm**: создание сущностей, архетипы,
+  `QuerySystem`, `ForEachEntity` — без ошибок в консоли браузера.
+- **KNI 4.2.9001 рендерит через WebGL** с XNA-API: `Game`,
+  `GraphicsDeviceManager`, `SpriteBatch`, `Texture2D.SetData` — совпадает с
+  кодом, который пишется под десктопный MonoGame.
+- Сборка тривиальна: обычный `Microsoft.NET.Sdk.BlazorWebAssembly` проект,
+  никаких wasm-workload-плясок не понадобилось.
+
+## Известные ограничения пути A (работа на этапе «веб-клиент»)
+
+1. **Пер-платформенная компиляция библиотек движка.** `MrGameEng.Graphics`,
+   `Content`, `Audio`, `UI` ссылаются на `MonoGame.Framework.DesktopGL`; для
+   веба их надо собирать против пакетов `nkast.*` (типы те же по API, но другие
+   сборки). Решение — msbuild-условие (`KniPlatform=BlazorGL` → nkast-пакеты),
+   без изменения исходников.
+2. **Шейдеры.** `Renderer2D` использует прекомпилированные `dotnet-mgfxc`
+   эффекты — KNI имеет собственный компилятор эффектов; совместимость надо
+   проверять отдельным спайком, прежде чем тащить батчер в веб.
+3. **Нет файловой системы.** Моды/дефы/атласы в браузер приезжают по HTTP;
+   текущая схема «собрать атласы при старте из PNG» в вебе не работает —
+   атласы пре-билдятся и кладутся в `wwwroot` (или приезжают с сервера).
+4. **Потоки.** `Task.Run`-загрузка контента и `Thread.Sleep`-пейсинг не для
+   браузера (клиенту `HeadlessHost.Run` и не нужен — цикл гонит
+   `requestAnimationFrame` через KNI).
+5. **Производительность не мерялась** (300 спрайтов — гладко); бюджет
+   сущностей в wasm-интерпретаторе будет заметно ниже десктопного, замерять
+   на реальной сцене с включённым AOT.
+
+## Решение
+
+**Путь A (KNI)** — основной для веб-клиента: переиспользуем ядро, сцены и
+в перспективе графику движка; код игры один на все платформы. Путь B остаётся
+запасным, если упрёмся в шейдеры (п. 2) или производительность (п. 5).
+
+Порядок работ не меняется: сначала `MrGameEng.Net` (WebSocket-транспорт +
+репликация — нужен любому пути) и сетевой мультиплеер на десктопе, затем
+`MrGameEng.Host.Web` поверх KNI по образцу спайка.
