Private by boundary. Loud by failure.
Security is enforced by the server, not by hiding buttons. Failures remain visible and traceable.
Server-side authorization
Every protected data request is authenticated and role checked by the backend. Navigation visibility is never the security boundary.
Tenant isolation
Listings, rules, watchlists, connections, tickets, and bidding records remain scoped to the resolved tenant and user.
Minimal credentials
Private connection material is encrypted, never returned through account APIs, and used only by supported flows.
Controlled mutations
Bids, deletion, engine controls, and account disconnection are separate confirmed actions with clear outcomes.
Fail-loud operations
Unavailable schemas, unhealthy adapters, and API failures produce explicit incident states with trace identifiers.
Human source of truth
GhostNode supports decisions; the originating auction platform remains authoritative for terms, price, availability, and bid acceptance.
