This runs systematic QA testing on your web app, finds bugs, then iteratively fixes them with atomic commits. You get three testing tiers: Quick for critical issues only, Standard adds medium priority bugs, and Exhaustive sweeps cosmetic problems too. It produces before and after health scores plus a ship readiness summary. The workflow is opinionated but practical: it verifies each fix works before moving on, which prevents the classic problem of batching changes and losing track of what broke what. Part of the gstack suite, so it integrates with their telemetry and learning system if you're already using those tools. Useful when a feature feels done but you want structured verification before deploying.
