# Container image for the Matrix intake bot — turns it from a bare nohup process into a managed
# service (docker compose `restart: unless-stopped` survives a Spark reboot).
#
# Build context is the REPO ROOT (see ../../docker-compose.yml), not this directory: the bot is
# NOT self-contained — spark.py reaches into backend/ingest/{llm,config,http_util}.py (stdlib
# only) via sys.path, so the image must carry both trees with the repo layout preserved. That
# keeps settings.load_env's REPO_ROOT (three dirs up from settings.py) = /app and spark.py's
# ingest path = /app/backend/ingest both correct at runtime.
