Scoped partner credentials use the exclusive `nxsk_v1_...` namespace. Each scoped key is bound at issuance to one organization, one canonical named environment, an explicit engine set, and a least-privilege capability set. A malformed, unknown, rotated, or revoked `nxsk_` key fails closed and is never retried as a legacy key. Capabilities used by this API are `runs:write`, `runs:read`, `engines:read`, `catalog:read`, `webhooks:manage`, `runs:defensibility:read`, and `runs:test`. Operation descriptions name the required capability. Grandfathered `nx_live_...` and `nx_test_...` keys retain their existing broad access during the compatibility window. ````
