This module contains no Orchestration runtime\n * dependencies — it is independent of `DispatchRunner`, `Message`, or `Tool`. The bundled\n * helper that constructs those lives in its own subpath and is a separate concern.\n *\n * The reason node ends in a tool call, and that tool call *is* its output. It never\n * returns prose to be parsed. The node's `outputSchema` becomes a forced tool's\n * `inputSchema`, so the model physically cannot answer unstructured: malformed args are\n * rejected before the handler runs and retried within `maxAttempts`. A dispatch that ends\n * without the tool being called is a halting node failure, never a fabricated result.\n *\n * This file implements the contract required by `ReasonNodeDefinition` and the\n * `ReasonerFn` signature. All functions are pure and side-effect free.\n */\n\nimport { NodeRef as NodeRefClass } from './encoding'\nimport { decode as decodeSchema } from '@nhtio/validation'\nimport type { Schema } from '@nhtio/validation'\nimport type { PromptPart, EncodableValue, NodeRef } from './types'\n\n/** Narrow a `PromptPart` to its `NodeRef` member.
