# Floors raised for 0.6.0: copy_thread/delete_for_runs/prune are langgraph-checkpoint
# 4.x base capabilities (validated working on checkpoint 4.0.0), so the floor must
# guarantee a 4.x-capable stack. langgraph 1.0.6 is the first release that *allows*
# langgraph-checkpoint 4.x (earlier langgraph caps it <4.0.0), so a langgraph floor
# raise is unavoidable; langchain-core >=1.0 keeps the "0.6.x = LangChain 1.x" story
# while still admitting LangChain 1.0/1.1 users. CI tests both this floor and the
# locked newest stack.
