📄 Description

Description

Ports the Python namespace API change (langchain-ai/docs#3496) to JS. StoreBackend.namespace now accepts a NamespaceFactory function (rt: Runtime) => string[] in addition to a static string[]. A BackendContext backwards-compat wrapper lets legacy (ctx) => [ctx.runtime.serverInfo...] factories keep working with a deprecation warning, following JS best practices for the migration path.

Test Plan

  • Verify namespace factory resolves dynamically from LangGraph Runtime (serverInfo, executionInfo, context)
  • Verify legacy BackendContext-style factories emit deprecation warning and still work
  • Verify static string[] namespaces continue to work unchanged

Opened collaboratively by Sydney Runkle and open-swe.
