Add the sol-import/top-level-import authority beside chat and route sol import through the native sol client. Preserve the two-request import flow: save or save-path first, then start with the staged path, timestamp, and force flag. Add a ClientItemIdProvider seam so parity vectors can pin deterministic client_item_id values while production emits uuid4 hex. Keep the frozen partial-failure form, staged {path} but processing was not queued, with a nonzero exit and no queued-success output. The existing sol-call/sol-chat partition counts remain 152/2/1/1.
