mir-backend-python-django

Make It Right (Django module). Django 5 + Django REST Framework specific reliability augmentation. Use alongside the mir-backend skill when the target stack is Django — it carries the mechanical footguns that the framework-agnostic skill deliberately omits: ORM N+1 with select_related/prefetch_related, queryset laziness and caching semantics, migration safety on populated tables (NOT NULL / index locking), transaction.atomic() and on_commit() boundaries, mass assignment through ModelForm and DRF serializers, async views with the Django 4.1+ async ORM, and signal side-effect traps. TRIGGER only when the Python backend stack is Django — building, reviewing, or debugging a Django view, model, serializer, migration, or admin. Always loads TOGETHER WITH mir-backend (the gates) and mir-backend-python (CPython runtime concerns: GIL, async/sync, fork-safety, cold start); this module only adds Django/DRF library mechanics. SKIP for FastAPI, Flask, or any non-Django stack (those get their own mir-backend-python-<framework> module), and for non-Python runtimes.
