Datapoint.Mediator.Authorization

A Datapoint.Mediator behaviour that authorizes commands, queries and stream queries for the current user, denying access by default. The rules live in your business layer, so they apply the same way from an API, a CLI or an MCP server. Register it with Datapoint.Mediator.Authorization.DependencyInjection.

public sealed class CreateInvoiceAuthorizer : IAuthorizer<CreateInvoice>
{
    public ValueTask<AuthorizationDecision> AuthorizeAsync(CreateInvoice action, ClaimsPrincipal principal, CancellationToken cancellationToken = default) =>
        new(AuthorizationDecision.AllowIf(principal.IsInRole("Finance")));
}

A decision can carry details of your own, such as the share or rule that applied, for your handlers (IAuthorizationContext) and audit log (IAuthorizationObserver); they never reach the caller. An action with no authorizer is denied, unless it's marked [AllowAnonymousAccess]. To authorize inside the database transaction, register AuthenticationBehavior first and the authorization behaviour after the transaction behaviour, with RequireTransaction. With no signed-in user, AuthenticationRequiredException is thrown.

Security: messages aren't authorized. Never publish a message built from user input: send an authorized command, and publish the message from its handler.
