Run a project with two Claude Code sessions that check each other. A builder builds one step of the plan at a time, with tests and evidence; an independent reviewer checks the exact commit in its own copy, re-runs everything, and answers PASS, FIX or STOP against a short list of what blocks. An optional tester makes adversarial passes.
