Published as module-typica. Define the things every service re-writes once and validate them everywhere: database and queue connection metadata that accepts whatever shape the config arrives in (and parses connection URIs), request and response schemas, identifiers, enums and logging.
The core is pure Pydantic. Optional connectors cover PostgreSQL, MongoDB, Redis, ClickHouse, Kafka, RabbitMQ, Elasticsearch and REST APIs, and need only the driver you use. Most of my Python engines are built on it.
