namespace SkillManagementBLL.Common;

// Abstraction over the SignalR hub push (SkillHub lives in SkillManagementSL — BLL must stay
// free of ASP.NET/SignalR types per CLAUDE.md). Concrete implementation:
// SkillManagementSL/EndPoints/Hubs/SkillHubNotifier.cs, wrapping
// IHubContext<SkillHub, ISkillHubClient>. Registered as a Singleton in
// SkillManagementModule.cs — mirrors WiBLL.Common.IWiHubNotifier exactly.
//
// Must never throw — a push failure is non-fatal to the underlying save that triggered it; the
// implementation logs and swallows (same contract as IWiHubNotifier's doc comment).
