 Business status: contact search, group search, receive messages, and receive file-list remain the stable MCP foundation. `isphere_send_message` and `isphere_send_file` are implemented as preview/contract paths, but production send/file remains blocked until logged-in B-route reachability and sent-record/ack correlation pass. N12-pre/offline evidence remains pre-gate context. Existing UIA selector/report/RPA work is auxiliary evidence and fallback support only; the project core is MCP communication capability for contacts, groups, messages, and files.
