Admit. Isolate. Meter. Destroy.
Every spawned guest is admitted, isolated, metered and destroyed. The spawn token cannot reach foundation identity, mail or DNS.
Residual risk
- Silicon supply chain — mitigated by configuration control, long refresh cycles and measured boot where available.
- Microsoft residual on SovMS — isolated to the application layer; identity remains customer-owned.
- Operator error on key material — dual-control procedures and offline key vaults.
Exit path
Open formats: ZFS send streams, LDAP/LDIF, PBS archives. A client can transfer the complete environment to different hardware or a different EU operator without proprietary lock-in.
