Sandbox

Test events without touching production behavior.

Sandbox rows, API keys, projections, replay previews, and workflow simulations must stay isolated from production. Use sandbox before enabling a workflow for customer-facing events.

Seed

Create sample data for an organization-scoped sandbox environment.

Send

Emit test events with a sandbox key or `x-eventstack-environment: sandbox`.

Replay preview

Preview projection rebuild effects before confirmed replay.

Production launch proof must show sandbox reset and replay do not cross organization or environment boundaries.
