Semesh
The launch layer for agent-built apps. Semesh exposes a Service Unit catalog plus the intended auth, database, runtime, and usage-billing deployment contract. Production deployment authorization is currently unavailable: the app_deployments.create Platform Action is disabled, and source deploy fails closed with deployment_authorization_unavailable before upload, build, payment, publication, or creation of a live URL. Existing app records can still be observed; that readback does not authorize a new deployment.
