The runtime holds no keys
External compute receives one short-lived signed link and a callback address. It receives no storage credential, keeps nothing, and can be replaced by in-boundary hardware through one setting.
Open-weight models run inside your boundary or through a runtime with no credentials and nothing retained. Retrieval is permission-scoped before generation, and every read, response and revision lands in an append-only audit trail.
System map. Inside a cutaway jurisdiction boundary sit a data plane, an orchestrator acting as the single writer, an in-boundary model runtime and an append-only audit log. An external runtime sits outside the boundary and receives only a short-lived signed URL, returning text through a marked port. A severed trace marks data leaving the boundary, which never happens.
Sovereignty is an architecture. If it lives in a contract clause, you do not have it.

Access rules travel with content into the index. A person cannot retrieve what they could not open, and the response does not disclose that a hidden record exists.
Every unavoidable vendor edge is documented and scoped. Data residency is enforced by architecture; residual metadata paths are named instead of hidden in a contract.
