- متریال field suggests unique BASE material names from the whole catalog
(brand/spec prefixes stripped; «راجین سیم مسی» → «سیم») — brand/specs
have their own columns.
- Save path reuses an existing material by full name only (no category
equality constraint, which never matched topic-named categories) so
selecting an existing material never duplicates it.
- Unit field: suggestion list no longer includes the row's own typed text,
which previously suppressed the create option; typing an unknown unit now
shows «+ [value] به عنوان واحد جدید» (registered immediately via
POST /units and added to suggestions).
