# =============================================================================
# SimpleAudit Studio — single-container image (local `docker run` + HF Space)
#
# Single-process image: Django web + embedded Hatchet + worker in one Python
# process. No Postgres, no supervisord, no external services. SQLite for the
# domain DB, embedded Postgres (sidecar binary) for Hatchet's queue.
#
# The container listens on 7860 (Hugging Face Spaces expect that port).
#
# Build:  docker build -t simpleaudit-studio .
# Run:    docker run -d -p 8000:7860 -v sa-data:/data --name simpleaudit-studio simpleaudit-studio
#         (web → http://localhost:8000, login studio / localdevpass123 — override with
#          -e BOOTSTRAP_PASSWORD=<strong> for anything shared)
# All data (SQLite database, embedded queue, chat) lives in /data: mount a
# named volume there to keep it across restarts and image updates.
