Detailed Description

Thrown when a decoded action fails ActionValidator<Action>::ready(...) on a server-side or local execution path, before Model::execute runs.

Raised by morph::model::detail::ActionDispatcher::registerAction's runner (the server dispatch path used by RemoteServer, every remote and Qt WebSocket topology) and by Bridge::executeVia's localOp (the in-process path used by LocalBackend) — the two sites an action can reach ungated: the runner by a hand-built envelope from an untrusted remote client, localOp by an action built by hand and handed to BridgeHandler::execute<Action>(). An action that did pass morph::flows::FlowSession::set<>'s gate (forms/flows.hpp) or the type-erased executeJson gate (ActionExecuteRegistry::registerAction) still reaches whichever of the two its topology dispatches through — FlowSession::fireStep goes through the handler like any other caller — and is simply re-checked there.

Deriving from std::runtime_error means existing catch (const std::exception&) handling — e.g. RemoteServer::dispatchExecute's strand catch, which turns any thrown exception into an err reply — keeps working unchanged; callers that care can catch/dynamic_cast the specific type instead.
