## Project Overview and Architecture
A concise high-level view of how the solution projects fit together, their runtime hosts (server, WASM client, MAUI) and how cross-cutting concerns are wired via dependency injection, mapping and real-time services. Diagrams below show dependencies, startup/service registration, Program.cs control and method-level flows.

This diagram maps core application interfaces (commands, queries, services, repositories) and shows where infrastructure handlers (e.g., TokenLimitHandler) connect. It highlights ownership: Application contains abstractions, Infrastructure implements runtime concerns.

This diagram details how Web.Client's Program.cs configures the WASM host: mapping profiles, MediatR handlers, AppDbContext factories and client-specific service substitutions (WasmKnowledgeService, WebPlatformService). It shows where Infrastructure and Application DI extensions are invoked.

This flow emphasizes Program.cs usage: which services are resolved on the WASM client, which are replaced by throwing stubs or Wasm-specific implementations, and how client startup triggers queries/commands.

This control-flow diagram traces runtime calls through Program into application commands/queries and platform service calls (e.g., vibration). It illustrates which runtime entrypoints trigger domain/application logic.

Layer view clarifies boundaries: Application owns domain contracts and DTOs; frontend owns runtime wiring and substitutes server-only implementations with client-safe stubs or WASM-specific services.

This method-flow highlights Infrastructure helpers and the real-time SyncHub lifecycle (connect, disconnect, progress updates) plus utility flows (content hashing, JSON repair). It shows who owns runtime behaviours for syncing and data integrity.
