- Flask + SQLAlchemy (MariaDB-compatible schema) battery tracking web app - 40 pre-seeded batteries (Eneloop, BONAI, Energizer NiMH) across 5 devices - Business rules: block retired assignment, brand-mix warnings, capacity checks - Mobile-friendly Jinja2 templates with inline CSS - waitress WSGI server via systemd user service (sbin/install-service.sh) - SQLite → MariaDB migration script (migrate_to_mariadb.py) - 26 passing acceptance tests (pytest + Flask test client) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
