Piñata Vision barcode/Name bits
Matching names
The following cards have similar second barcode rows and matching last bytes for row 2, raising the possibility that row 2 is obfuscated differently from row 1's obfuscation (set).
These cards also share pinata names.

Non-matching names
The following cards have similar second barcode rows and matching last bytes for row 2, but their pinata names are different. However, their names are all the same length, raising the possibility that a) there is a length "byte" for the name field, and b) the row 2 obfuscation set selection involves bits from that field.

Decoded names
Drop row 1 from the barcode to focus on row 2. Change IDs to match the ASCII value of the name's 2nd character (e.g., Kieran, i = 105 decimal).

The reader script decodes the columns holding character 2 of the name, and the decoded values are a match.

Repeating the same process to look for columns matching ASCII values for the following 3 characters, we can read name data from the barcode. It looks like the name field has an (undiscovered) length "byte," since the name data does not appear to be zero-terminated.

Unfortunately, the good (other) variants don't appear to keep their name data in the same location. One possibility is that the GoodVariant cards have additional data located before the name data, which shifts the underlying name data in the structure.
