Sovereignly

Accounting firms serving cross-border clients may need evidence about where client data is processed and stored. The supplied research confirms private deployment options and one regional inference interface, identifies an August 2, 2026 legal milestone and finds no accounting assistant combining jurisdiction selection with request-level receipts. The original stage verified one interface. Sovereignly replaces the misleading idea of a single residency selector with a processing topology. Inference location, primary storage, logs, caches, backups, telemetry, support access, encryption keys, disaster recovery, model improvement and subprocessors are separate. A receipt can state what the verified system observed for one request under one configuration; it cannot prove device-wide no-egress, legal data residency, sovereignty, transfer validity, professional compliance or complete provider behavior. Country or region selection is a routing input, not a legal decision. Every matter requires client instructions, data classification, approved topology, transfer and subprocessor review, retention and fallback policy. When required evidence is missing or routing cannot be honored, the system fails closed rather than silently using another region. Voice and chat content remain client data; capture requires purpose, notice and minimization. Generated accounting assistance is a draft with citations and reviewer approval, never an autonomous accounting conclusion or filing.
