Note

Caches stream instances, normalizes Buffer-like results, and updates RPC processors to support sync handlers with safer request handling.

• Core Execution (call-step-file.ts):
  • Cache StreamFactory instances via WeakMap and reuse with getStreamInstance.
  • Build streams from Object.entries and pass to runner payload.
  • Normalize result.body when received as Buffer-like JSON (convert to Buffer).
  • Improve stdout handling: parse likely-JSON logs; otherwise log as text.
• RPC Processing:
  • Allow RpcHandler to return sync or async; handle now consistently returns a Promise.
  • RpcProcessor and RpcStdinProcessor:
    • Guard when closed; respond with error for unknown methods.
    • Handle both sync and Promise-like handler results without throwing.
    • Add exit/close/disconnect guards and line-based stdin parsing reliability.
