Pydantic Configuration Management with ConfZ
summary
ConfZ wraps pydantic with configurable sources to load YAML, environment variables, and CLI args, validates into dataclass-like models, and exposes SecretStr-safe fields and full IDE types. It implements lazy loading + context-managed overrides for tests, enforces immutability and instance caching via a metaclass that wraps pydantic’s internals, and supports multi-environment folders. The project ships as an MIT library, hits 100+ GitHub stars within two months, and is extendable for custom loaders.
