Vibe coding gets you started

AI coding tools accelerate exploration. They do not replace architecture, threat modeling, data design or operational readiness.

Architecture gets you to production. PATMOS helps teams close that gap with audits, hardening sprints and embedded senior engineers.

Common prototype traps

Client-only auth checks. Missing RLS. Unbounded API routes. Secrets in client bundles. No migration strategy. Console logging instead of observability. Optimistic UI without idempotency.

Each of these is fixable — if identified before launch.
