Report #4054
[architecture] How do I prevent two agents from clobbering the same state or file?
Assign one writer per mutable channel; use private state fields or namespaced workspaces per agent; share only immutable inputs and explicit outputs.
Journey Context:
Concurrent or sequential agents that read and write the same key create silent data loss. LangGraph's state model lets nodes write to private channels and define explicit input/output schemas. In file systems, give each agent its own directory prefix and merge results via a reducer or aggregation node. Unambiguous ownership matters more than elaborate locking because LLM agents are not transactional by default.
