# apps/worker — headless BullMQ worker + domain-event stream consumers.
#
# WORKSPACE NOTE: this app is part of a pnpm monorepo (pnpm-workspace.yaml:
# apps/*) and has a `workspace:*` dependency (@factory/shared) plus the shared
# Prisma client from prisma/. A monorepo package cannot be built in isolation,
# so build from the repository root with context at the root:
#
#   docker build -f apps/worker/Dockerfile -t factory-worker .
#
# The image has no business HTTP surface — the only port it listens on is the
# health server (TASK-0009 item 4): EXPOSE 4003 (/health + /health/ready).
# It talks to Redis (BullMQ + factory:events streams), Postgres, OpenSearch,
# S3, SMTP, ClamAV and the AI endpoint via environment (see .env.example).
