@repo/api — tRPC Router Definitions

tRPC routers that call controllers from @repo/core. Each procedure validates input and delegates to a controller.

Rules

• NEVER put business logic in routers — delegate to controllers
• Input validation uses Zod schemas
• Each domain gets its own router file

Adding a New tRPC Router

1. Create src/router/{domain}.router.ts
2. Import router and publicProcedure from ../trpc.js
3. Define procedures (.query() for reads, .mutation() for writes)
4. Each procedure calls a controller from @repo/core
5. Add router to root appRouter in src/router/index.ts
