Ktor Routing

Parent context: See root AGENTS.md (lines 147-167) for error handling and routing rules. This skill provides concrete code examples that complement those rules. The codebase uses Ktor only -- no annotation-based web frameworks.

When to use me

• Trigger: building a new REST endpoint or fun Route.X() extension
• Trigger: wiring a new app's Application.<appName>() module
• Trigger: handling errors via StatusPages and ApiError
• Trigger: adding authenticate("name") { ... } JWT blocks
• Trigger: throwing badRequest(), notFound(), conflict(), etc. from a route handler

Route as extension function

Routes are defined as extension functions on Route. Dependencies are passed as constructor-style parameters. No annotations, no DI framework.
