Guardian is PromptUI's reliability layer. It watches for production issue signals, maps errors back toward generated app source, classifies repair risk, and records proof around fixes instead of treating every model patch as automatically safe.
What Guardian is built to do
Guardian connects Sentry-style issue data, source mapping, risk classification, fix planning, sandbox verification, hotfix deployment proof, and recovery metadata. Its job is to make generated app repair more auditable.
Proof before resolution
PromptUI's Guardian work emphasizes deploy readiness and route-aware live proof. A hotfix should not be counted as resolved just because code changed; it needs deployment state and proof appropriate to the route type.
Rollback and manual review
When a hotfix deployment fails or proof does not pass, Guardian records the failure and keeps manual review visible. Recovery planning can include previous-good deployment information and alias recovery paths where available.
What to say publicly
Guardian is a serious reliability capability, but claims should stay evidence-based. Controlled repair proof is different from broad organic customer-cohort proof, and PromptUI should keep those distinctions visible.
