Architecture

Runtime split

• src/ runs on Vercel as a Next.js App Router app.
• worker/ runs on Railway for jobs, scheduling, and integration work.
• Shared schema and types live in src/db/schema/ and src/types/.

Key boundaries

• Auth/session: Better Auth
• Data authz: Supabase Postgres RLS
• Async workflows: worker jobs
• Compliance checks: centralized status transition and validation logic
