Mirrors vs staging environments
Staging is shared, slow to reset and expensive to keep close to production; a twin starts in seconds and is seeded per session.
Where they differ
Each console session opens on a fresh, seeded world.
Staging keeps real integrations; a mirror keeps their recorded behaviour.
When to pick which
staging environments remains the right tool when its own strengths are what you need; a mirror is for testing an agent against a backend that behaves like production without being production.
