single-shot-software-build

Turn a one-line product idea into a complete, running full-stack system (front + back) in one orchestrated multi-agent build. The architect expands the brief with taste, freezes a compiler-enforced contract (types + config + design system) after an adversarial pre-freeze gauntlet (≥3 refute-reviewers), product-directs every screen and endpoint in prose, fans out parallel disjoint-ownership agents (decomposition verified by check_plan.py), hardens via compile loop → multi-lens review → adversarial verification → mechanical gate, then closes the loop with Playwright-captured, scored product-design + UX judges (including a driven first-time-user task) iterating until every axis clears the bar. Generalization of the contract-first game method to front/back systems; model-tiered.
