This task file previously described the old request_context lane. That lane
has been replaced by the LangGraph multi-agent context network in plan.md.
Current ownership shape:
- Desktop runtime owns LangGraph orchestration and the user-agent
ask_retrievertool. - Retriever owns server-backed reads through
agent_ctxandglobal_ctx. - Updater owns automatic checkpoint writes through
commit_memory_update. - Server owns memory storage, retrieval primitives, and exchange audit rows.
Use goal.md, plan.md, and the app/server READMEs as the active source of
truth.
