Data
In-memory data store using Pydantic models.
This module is NOT thread-safe and is intended for demos and scaffolds only. This module provides a minimal, process-local data store for the model-based CRUD example application. It stores and returns domain objects defined using Pydantic models and is intended solely for demonstration and scaffolding purposes.
The implementation intentionally avoids: - persistence - concurrency guarantees - transactional semantics - validation beyond what Pydantic provides
It is not part of the openapi_first library API surface.
