Shared-library development

The distribution is rpt-common, imported as rpt_common, with Python 3.13+, SQLAlchemy, and Alembic. The postgres extra adds Psycopg. There is no PyPI release or runtime image. Use the library README for setup and test commands.

Central Auth declares this library from Git main and uses an editable sibling checkout during development. Its image copies only shared package build inputs from the named context pycommon. Its CI resolves common/protobuf revisions once per run. The package is available on the public main branch; consumer builds use the revision resolved at the start of each workflow run.

Change model definitions and migrations together. Verify fresh/repeated upgrades, explicit node IDs, disabled defaults, validation, and packaged migration resources. The central-service integration suite also validates real PostgreSQL, SELECT-only accounts, encrypted connections, and read-only execution.
