 @* Bulk manual tag-entry grid for the v3 /raw tree: add MANY new tags at once under a Device or a
    TagGroup. Each row carries Name / DataType / AccessLevel / WriteIdempotent / PollGroup plus a
    per-row driver-typed TagConfig editor (revealed in an expandable full-width sub-row — the grid stays
-   compact). The owning DriverType (fixed by the device) drives the typed-editor dispatch. On commit each
+   compact), each fed the merged Driver+Device probe config so its address picker can browse the live
+   device. The owning DriverType (fixed by the device) drives the typed-editor dispatch. On commit each
    row is created via CreateTagAsync; committed rows drop off, failed rows stay with their inline error so
    nothing is lost silently. Visibility is @bind-Visible; a successful commit raises OnSaved. *@
