+# Release and access status
+
+## Decision: Mode B — Private Developer Preview
+
+Active version: 0.2.15, derived from package.json#wrnexus.version. All 25 installed @wrnexus packages resolve to 0.2.15. On 2026-07-12, npm view using a clean empty user config returned E404 for @wrnexus/cli@0.2.15 and @wrnexus/core@0.2.15. The repository remote is a private WorkRoot Git service and no public license file exists.
+
+External users cannot execute an installation without approved private registry credentials. The truthful CTA is Request preview access. After approval, the canonical command is bunx @wrnexus/cli@0.2.15 create my-app. Tokens must never appear in documentation or source.
