Why this is canonical

'Rails' in platform naming signals an opinionated, convention-driven build surface — the layer that abstracts infrastructure complexity and lets builders ship fast. Applied to federation, it names the developer-facing toolkit and framework layer for cross-boundary AI systems. On .ai, it speaks to the build community.

Where it fits

A few directions this coordinate opens —

Developer framework / SDK
An opinionated framework brand for building federated AI applications without reinventing cross-boundary coordination.
AI developer tools, SDK vendors, platform-as-a-service builders
Enterprise integration platform
Federation rails as the structured integration layer connecting enterprise AI systems across trust zones.
Enterprise integration vendors, iPaaS platforms, B2B middleware
