Platform Objectives¶

maintain lifecycle continuity from planning to operations
preserve auditable links between requirements, evidence, and release decisions
reduce cross-team handoff overhead
support operationally informed governance decisions

Runtime Stack¶

Layer	Technology	Role
application	Django 6	web runtime and workflow orchestration
datastore	PostgreSQL	transactional persistence
async broker/result	Redis	queue and result backend
async execution	Celery	background tasks
orchestration	Docker Compose	local/deploy service orchestration
ingress (deploy)	reverse proxy	request routing and edge handling

Repository Orientation¶

Path	Purpose
`app/`	Django project root and domain modules
`app/app/`	settings, URLs, WSGI/ASGI, celery app
`scripts/`	test/smoke/data/ops helper scripts
`proxy/`	deploy proxy assets
`docker-compose.yml`	local topology
`docker-compose-deploy.yml`	deploy topology

First Useful Commands¶

docker compose run --rm app python manage.py check
docker compose run --rm app python manage.py showmigrations
./scripts/run_smoke_tests.sh
