Shared Python utilities

pyCommon owns Python code shared across projects, including the SQLAlchemy node-credential model and its migrations. Central Auth reads the model; an operator-managed process writes credentials. There is no shared-library service endpoint or standalone runtime image.

Database models live in rpt_common.models; migrations remain in rpt_common.migrations. Other shared Python modules can be added alongside these packages.

Start with the model, migrations, and development. Operator command and Job examples are maintained in the library README and Central Auth README. The package is available from Git main; follow the library README for installation and dependency pinning.
