final class ThreadHandlerImplementationMarker extends Object
Every user implementation of a handler type a thread-spawning call takes (TCPHandler, the ready handlers, SignalHandler - IsThreadSpawningCall.handlerTypes()) is a concurrent entry point and a published handler, wherever it is written and however it reaches the call (review 2026-11-02, H2). Phase 3 marks the handler at a call it can see (tcpServer.accept(handler)); a handler that arrives through a parameter, a field or a call result typed TCPHandler names only the core abstract type there, which is no callable, so neither E08251 nor the registered-type fact ever reached its body or its captures. Fail closed: a handler of one of these types exists to be run by the runtime on its threads, so every one is marked - on the user's own symbol, never a core one. Run before the concurrent-entry-point propagation.
