Why we stack
Vertical integration
Most business software is a federation of vendors held together by glue code. Every new client is a new integration. We collapsed it: one substrate, one engine fleet, one application layer, one client config. The vertical stack is the integration.
Substitutions are bounded. Swap a Ring 0 docker, the engines keep running. Swap a Ring 3 blueprint, the client config moves with it. No circular dependencies.
Competitors sell horizontal SaaS (CRM, ticketing, ERP). They leave the integration as the customer's problem. We ship the full vertical — substrate to client config — as one install.
Ring 0–2 is the platform install (hours). Ring 3 is the vertical blueprint (days). Ring 4 is per-client config (a week). 30 days end to end. Slater Byrne is the validator.
