crestapps-core-signalr

Skill for SignalR in CrestApps.Core 2.0. Covers AddSignalR on the AI suite builder and AddCoreSignalR with a tenant path prefix and the store-committer hub filter, the global hub defaults it sets (camelCase JSON, eight parallel invocations per client, a stream buffer of 64) that realtime WebRTC signaling depends on, per-hub chat options with ConfigureCrestAppsChatHubOptions, HubRouteManager path and URL generation, mapping hubs in minimal hosting, connection-level and per-invocation authorization for AIChatHubCore and ChatInteractionHubBase, access tokens for headless clients, reading the caller through Context.User and IUserAccessor, pinning the browser SignalR client with an integrity hash, and Redis or Azure SignalR scale-out. Use it when mapping CrestApps chat hubs, generating hub URLs for JavaScript clients, securing hubs, or troubleshooting stalled realtime handshakes, queued hub calls, or cross-tenant hub URLs.

# CrestApps.Core SignalR

The `CrestApps.Core.SignalR` package registers SignalR with CrestApps defaults and a `HubRouteManager` that builds hub paths and absolute URLs (with an optional tenant prefix). The chat hubs themselves (`AIChatHubCore<TClient>`, `ChatInteractionHubBase`) live in `CrestApps.Core.AI.Chat`; see `crestapps-core-chat-interactions`.

## Register SignalR

Through the AI suite builder, optionally with the store-committer hub filter so staged store writes are committed after each hub invocation:

```csharp
using CrestApps.Core.SignalR;

builder.Services.AddCrestAppsCore(crestApps => crestApps
    .AddAISuite(ai => ai
        .AddSignalR(pathPrefix: "", addStoreCommitterFilter: true)
