# PostgreSQL Admin Control Plane

## Overview
This repository contains a production-oriented PostgreSQL admin panel with:

- `backend`: Express + TypeScript API, RBAC, audit, session management, SQL guard
- `frontend`: React + TypeScript admin console
- `infra`: SQL bootstrap for control and target databases
- `docker`: production-style images and reverse proxy

## Key Design Decisions
- Metadata, sessions, RBAC, and audit live in a dedicated control database.
- Managed PostgreSQL access is mediated by the backend only.
- Dynamic schema operations use `pg` with validated identifiers instead of an ORM.
- Permissions are enforced on the backend for every sensitive route.
- The UI preserves the visual direction of the original `index.html`, but is split into modular React components.
