-CultLib consequence (source read, `src/GameCult.Caching/CultCache.cs` at main 16074345): the C# document path uses runtime reflection (`GetProperties` :1105, :1138; `MakeGenericType` :1330) and MessagePack's `DynamicObjectResolver` (comment :1274), which emits IL at runtime. Neither NetWasm nor Mono wasm AOT runs emitted IL, and NetWasm refuses reflection outright. Any C#-in-the-browser option therefore needs a reflection-free, source-generated CultCache codec first. The same codec is what NativeAOT and Unity IL2CPP consumers need.
+CultLib consequence (source read, corrected same day): the C# path reflects at document registration, not necessarily per record. `CultCache.BuildDescriptor`/`DiscoverMembers` (`src/GameCult.Caching/CultCache.cs` :689, :1087; `GetProperties` :1105, :1138; `MakeGenericType` :1330; `ConstructorArity` :1277) walk members and constructors to mirror MessagePack's member rules for the descriptor and schema catalog, and `CultDocumentResolver` (`src/GameCult.Caching.MessagePack/CultDocumentMessagePackSerialization.cs` :14-30) builds `CultRecordRef<>` formatters with `MakeGenericType` + `Activator.CreateInstance`. Document formatters come from MessagePack's `StandardResolver` (:61), which in MessagePack 3.x prefers source-generated formatters and falls back to the IL-emitting `DynamicObjectResolver` only for types with none. An earlier version of this paragraph said the codec emits IL at runtime; that rested on a code comment (:1274) and was not established. Whether every [CultDocument] type gets a generated formatter, and what NativeAOT and NetWasm say about the registration path, is for a probe to establish.
