# Db Sqlite Overview

The Db Sqlite module provides a lightweight SQLite runtime facade and framework adapters for local
development and test environments.

## Capabilities

- Local SQLite connectivity with safe execution helpers.
- Health diagnostics plus a tables/schema snapshot endpoint.
- Shared configuration defaults with environment-driven override support.

## Architecture

- Runtime facade exposes `health_check()` and `list_tables()`.
- FastAPI adapter registers routes under `/db-sqlite/*`.
- NestJS adapter mirrors the same surface with a dedicated health controller.

## Security considerations

This module may touch sensitive data or privileged actions depending on how it is configured.

- Security: treat the DB file path as sensitive when running on shared hosts.
- Threat model: protect schema endpoints to avoid leaking table names to unauthenticated users.

If you operate in a regulated environment, include a brief audit trail strategy (what you log,
retention, who can access).
