- backend/alembic/* — alembic infra (env.py, script.py.mako). versions/ empty for now; first migration goes in Stage 2a when models are finalized. - backend/Dockerfile: bake alembic.ini + alembic/ into the image so `docker compose exec backend alembic upgrade head` works in prod. - backend/db/init/99_drop_unused_extensions.sql + bind-mount in both compose files: drops postgis-image's TIGER/topology/fuzzystrmatch on fresh volumes. - .pre-commit-config.yaml + pre-commit in dev deps: ruff/prettier on commit to stop CI failures like UP035 from leaking out. - ops/backup.sh, ops/restore.sh: pg_dump cron script with optional Selectel S3 upload. 7-day local retention. Restore guard: requires RESTORE_CONFIRM=yes. - Makefile: new targets `make migration NAME=...`, `make pre-commit-install`. - backend/.env.example: SENTRY_DSN comment with sentry.io reference.
