"""U-014's real-call coverage, scoped deliberately: plan_documents (4 real
Planner calls producing BRD/PRD/SDD/Benchmark for the snake-game scenario
REQ-01~14 uses throughout the SDD) is cheap and fast, like every other real
test this session (~$0.05-0.15/call). The Coder/Validator half
(run_end_to_end in full) is a different order of magnitude -- real code
generation + real test execution, plausibly minutes and real $ -- and isn't
run automatically here; see the session notes for why.
