"""U-004's actual A-2 validation: a REAL `claude --agent planner -p` call against
a deployed target project. Gated behind RUN_REAL_AGENT_E2E=1 (CLAUDE.md Testing
constraint) -- costs real API usage, skipped by default in normal
`python3 -m unittest` runs, matching graphloop's RUN_REAL_AGENT_E2E precedent.
