Name data
Based on released GoodVariants and Blackariants cards, encoded names are 3 to 9 characters long, the longest (and only 9-character name) being Francesca.
Other cards with longer names include Uncle Tusk, Fiddy Pence, Maximum Carnage, and Geckiesaurus Rex.
Based on the above names, the name length data is possibly a 5-bit field (0-31, with the likelihood that 0 indicates the absence of a variable-length name field to follow).
From the results of (obfuscation set C) cards that have been decoded so far, it's possible that the name itself may be encoded as (7-bit?) ASCII characters. Other sets need to be checked to verify if punctuation and spaces are likewise encoded as ASCII.
It's uncertain yet if/how accented or multi-byte Unicode characters (e.g., CJK) are encoded.
Location of name length bits
GoodVariants and Blackariants cards encode name length data in row 2, as determined by checking rows 1 and 2 for all obfuscation sets. It's likely that PlaceTag species also have a name length field in row 2, although the lack of specific name data for those cards makes it impossible to verify at this time.

Location of name data
Names appear to be encoded starting in row 2, with longer names continuing on to row 3.
Decoding name data
By decoding the name length field, then decoding the following namelen characters, names can be read from the barcode. (Results stop at 6 characters, due to the lack of enough similarly-obfuscated longer-name cards.)

Matching names
The following cards share pinata names, and belong to the same (row 2) obfuscation set.
Cards that also share matching variant data have nearly identical row 2 barcodes, differing in only a few bits.

Note that the first two cards share the same variant data, and that their row 2 barcodes are nearly identical.

Again, the first two cards share the same variant data, and their row 2 barcodes are nearly identical.
The third card happens to share a matching pinata name, but its row 2 barcode is obfuscated differently. Although name length does seem to be one factor in row 2 obfuscation set selection, another factor (such as variant bits or GoodVariants ID) may jointly determine how row 2 is obfuscated.
Also notable (but unrelated) is that the row 1 barcodes for the two Juicygoose cards are identical. The cards do share the same species ID (and use cost). It's unknown at this point if the matching names have any influence on the row 1 barcode, but the differing variant data appears to be completely unrelated to row 1.

Non-matching names
The following cards belong to the same (row 2) obfuscation set, but have differing pinata names. 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.

Assuming the names are encoded as ASCII, change IDs to match the ASCII value of the name's first character (e.g., Maya, M = 77 decimal).

This process can be repeated to look for columns matching (ASCII) values for each succeeding character, although the diminishing number of longer-name cards start to make it difficult or impossible to correctly identify relevant columns.
E.g., obfuscation set C only has 2 cards so far that have names of 7 or more characters:
egrep "^[0-9A-F ]{32}C" barcodes.txt | ./barcodetxt2bitdiff.pl --short --name=7
Black_orangebutterfl 105 E471793A7872A38F71B6E394DCDEE3BC Character 7 = i (Benjamin)
Black_unicorn 115 BC8174A07DFE06E31098FCBC0C65C0AC Character 7 = s (Francesca)
