"""M4 pilot (#513): publish OPPS reference tables to the DuckLake lakehouse.
Reads the OPPS tables from the local DuckDB (read replica when present)
and writes them to DuckLake via ``aco.lake.DuckLakeContext.save`` — the
Context write path this pilot exists to exercise. Config comes from
``stack.toml [lake.ducklake]``; the postgres catalog password from the
``POSTGRES_PASSWORD`` env var.
The catalog host and RustFS are compose-internal, so this runs inside a
data-network container:
docker exec -e POSTGRES_PASSWORD=... notebooks \\
env PYTHONPATH=/home/kert/src uv run --project /home/kert/workspace \\
python /tmp/publish_opps_to_lake.py
