NAMESPACE_AMBIGUOUS

What failed

Crux inferred a namespace that may not safely separate production, preview, local, or shared-substrate environments.

Why

Every durable row, cursor, idempotency key, and wake message includes a namespace. Ambiguous namespace inference can make environments share runtime state accidentally.

What still works

The configured runtime may still operate, but setup/preflight warns so you can pin the environment boundary before deployment.

Fix

Set an explicit namespace:

CRUX_RUNTIME_NAMESPACE=production

Or pass namespace in the runtime config.
