… from #19) langchain 1.2.x → 1.3.15, langgraph 1.0/1.1 → 1.2.11, langchain-aws 1.7.1, langchain-mcp-adapters 0.3.2, langgraph-checkpoint-aws 1.2.2, copilotkit 0.1.83 → 0.1.94, claude-agent-sdk 0.1.48 → 0.2.139, bedrock-agentcore 1.21.0, ADOT >=0.19.0, plus pydantic/PyJWT/requests/ urllib3/python-multipart across langgraph-agent, agui-langgraph-agent, claude-sdk-agent and claude-sdk-multi-agent. mcp stays 1.29.0: claude-agent-sdk 0.2.139 and langchain-mcp-adapters 0.3.2 both still require mcp<2.0.0, so #19's mcp==2.0.0 is uninstallable. The copilotkit ceiling recorded in this repo's notes is GONE — 0.1.94 declares requires_python <3.15,>=3.10 (0.1.83 capped it at <3.13) and only langgraph<2 / langchain>=0.3.0, so the AG-UI langgraph pattern is no longer pinned to langchain 1.2.x. Its Dockerfile still targets python 3.12; moving it to 3.13 is now possible but is its own change, not a dependency bump. Verified (the checks GitHub CI cannot run): - arm64 build + 'import agent' in-image, all four: langgraph-agent (py3.13, langchain 1.3.15, langgraph 1.2.11, mcp 1.29.0), agui-langgraph-agent (py3.12, same versions), both claude-sdk patterns (claude-agent-sdk 0.2.139, mcp 1.29.0). - LIVE, hardest path first: deployed AGENT_PATTERN=agui-langgraph-agent, UPDATE_COMPLETE, runtime protocol confirmed AGUI, and 'invoke.py --agui' returned typed AG-UI events with a real gateway web-search answer and cited URL. That covers copilotkit's AG-UI wrapper, the langgraph checkpointer against AgentCore Memory, the MCP adapters against the gateway, and the M2M token vault on the new versions. - Rig restored to AGENT_PATTERN=orchestrator.

Final slice from #19:
langgraph-agent,agui-langgraph-agent,claude-sdk-agent,claude-sdk-multi-agent— the patterns with the tangled constraints.claude-agent-sdk 0.2.139andlangchain-mcp-adapters 0.3.2both still requiremcp<2.0.0.A constraint just disappeared
This repo carried a note that copilotkit caps the AG-UI langgraph pattern at Python 3.12 and langchain 1.2.x. copilotkit 0.1.94 lifts it:
requires_python <3.15,>=3.10(0.1.83 said<3.13), and it now only asks forlanggraph<2/langchain>=0.3.0. Moving that pattern's Dockerfile to Python 3.13 is now possible — left as its own change, not smuggled into a dependency bump.Verified — the checks GitHub CI cannot run

#21 (root toolchain) → #22 (strands family) → this one. Independent files, so order only matters for a clean CI signal. Once all three land, #19 can be closed — it's fully superseded and uninstallable as written.
