Key gotcha: lambda_agent_api pyproject.toml says requires-python>=3.14 but runs on 3.11 — Dockerfile needs uv pip install --ignore-requires-python. platform-agent local clone is 11 commits behind origin/main — must pull before execution. Wave structure: 04-01 (Wave 1, alone) → 04-02 + 04-03 (Wave 2, parallel). All old thread_id/AgentSessionClient logic gets replaced — sdk/agent_session.py becomes mostly dead code or deleted."
