Core Concepts

This page is a stub. Content coming.

To cover

• Pipe — handle(Request, Response, array $args, callable $next): Response; onion middleware, short-circuiting
• Handler — handle(array|HandlerInput): ?HandlerResult; one unit of business logic
• HandlerInput — typed input constructed from raw body + optional Validator
• HandlerResult — success/data/errors/meta; injected instance, never static
• Listener — a Handler registered on an event name (same interface, returns null)
• How the same Handler is reused across HTTP and events
