# Environment Variables Reference
All configuration for the Orion platform is managed through environment variables, loaded
via Pydantic Settings from an `.env` file or the process environment. This page provides a
complete reference for every variable recognised by `app/core/config.py`.
Variables are read at startup and exposed through the `settings` singleton. In most cases
the defaults are tuned for local development; production deployments **must** override the
security-sensitive values listed in the [Production Checklist](#production-checklist) at the
bottom of this page.
---
## Core / Project
Metadata used in the OpenAPI schema and health endpoints.
| Variable | Description | Default | Required |

| `VERSION` | Semantic version reported by the platform | `2.2.0` | No |
---

## Admin Initialisation
Used by `init_production.py` and the database seeder to create the initial platform
administrator account.

The default `ADMIN_PASSWORD` is `admin123`. The production validation check will emit a
warning if this value is left unchanged.
