- SORF (slip-on RF) rows are identical to PLATE rows in all dimension fields; shown once.
- Blind rows record ID as [0.0] in source; omitted.
- Verified flag values are copied from the source: 'STD', 'STD~ID' or 'CHECK'. The source does not define them; 'STD~ID' presumably means standard dimensions with a derived/non-standard ID, and 'CHECK' rows were flagged for review.
- Size column is the NB taken from the source Key (e.g. 'NB150'); 'Size label in source' is the Size cell as typed.
