Profiles define the rules. Connectors plug into systems.

Profiles define. Connectors integrate. Apps productise. Plugins extend.

Hierarchy

From Core Protocol to Plugin — one tree.

KYE Protocol™ stacks five layers, each one a clean contract over the layer below. The same authority object travels from spec to runtime to evidence.

1. L1L1KYE™ Core Protocol™ — vocabulary, schemas, runtime, decision codes, audit chain. The base contract.
2. L2L2KYE™ Profiles — domain rules: kye.payments.v1, kye.healthcare.v1, kye.federation.v1, etc. (58 v1.0 normative)
3. L3L3KYE™ Connector Profiles™ — integration-category rules. This page. Each profile binds a family of connectors to a shared authority model + event family + evidence shape + conformance suite.
4. L4L4Individual connectors — specific systems (Stripe, Shopify, OpenBankProject, NHS API, etc.) under their parent profile.
5. L5L5Apps · Plugins · Widgets — KYE™ App Store productises · KYE™ Plugin Marketplace™ extends.
