- Add RoleFn<T>, AdapterFn, AdapterBinding types to workflow-protocol - Mark AgentFn, AgentFnResult, AgentBinding as @deprecated - Refactor createWorkflow to accept AdapterBinding instead of AgentBinding - Adapter returns typed meta directly — no more extract call in workflow loop - Add buildThreadInput (ThreadContext-based), keep buildAgentPrompt as deprecated wrapper - Update template bundle-entries to wrap AgentFn as AdapterFn - Update solve-issue tests to use AdapterFn directly
