Tenant boundaries first
Every commercial record is scoped by store identity, membership and PostgreSQL row-level security.
Part 1 · architecture & security foundation
Commerce infrastructure designed to keep every store in its lane.
K2S is an original SaaS foundation for modern commerce teams: isolated tenants, auditable authorization, policy-driven plans and a reusable API boundary for web and mobile.
K2S request path
Business rules are never entrusted to the browser.
- 1React web console or future mobile client
- 2Authenticated, rate-limited API boundary
- 3PostgreSQL with tenant context + RLS
- 4Private object storage and external service adapters
Deployment note: database provisioning remains server-side; this console deliberately does not expose connection strings or privileged writes.
Foundation principles
The first K2S release establishes controls that remain useful when a store has one product or operates across regions.
Server-held secrets
The browser never receives database, payment-provider or storage signing credentials.
API-ready domain model
A versioned API boundary keeps web and future Android / iOS clients on the same business rules.
Built to share one core with mobile.
Typed domain contracts and authorization rules stay server-side, ready for Android and iOS clients.
