Root cause

Alembic upgrade head uses engine_from_config with a synchronous postgresql:// URL from alembic.ini. SQLAlchemy requires psycopg2 (or psycopg2-binary) as the sync driver.

The old 2026.06.08 image inherited psycopg2-binary 2.9.12 transitively from cartsnitch-common. The standalone image does not have cartsnitch-common, so the driver is missing — causing ModuleNotFoundError: No module named 'psycopg2' and immediate pod CrashLoopBackOff.

Change

Add psycopg2-binary>=2.9 to [project].dependencies in pyproject.toml.

Unblocks

CAR-1422 / CAR-1211 UAT receipt path verification.

fix: add psycopg2-binary to runtime deps (CAR-1422) ... 87a7d63aeb

alembic upgrade head uses SQLAlchemy sync engine with postgresql:// URL,
which requires psycopg2. The old image had it via cartsnitch-common;
standalone image needs it explicit.
