Deployment Environment

Railway Config

Railway build and deploy settings are mirrored in apps/*/railway.json. Keep each service root directory and custom config path aligned with the checked-in app directory.

Preview Databases

Preview environments are named beef-pr-<PR_NUMBER>. The Neon branching workflow creates the PR branch and updates Railway preview variables.

Brain preview wiring needs both DATABASE_URL and DIRECT_DATABASE_URL. Setting only DATABASE_URL is insufficient because Prisma migration and runtime paths can read DIRECT_DATABASE_URL.

Sirloin preview wiring needs SIRLOIN_DATABASE_URL pointed at the Neon rump database.

Health Checks

Healthcheck paths come from the service Railway manifests. Round and sirloin expose /health on the same socket as their gRPC listener so Railway PORT remains aligned with the primary service port.
