"""diff_biblio 0.1.0: random differential run of tpc_biblio, Python against
PHP. Usage: python3 diff_biblio.py <seed> [count]. Writes its cases to a
temporary file outside the tree (kept where TPC_DIFF_CASES names it)
(count cases per function: doi, shape, arxiv, isbn, issn, pmid, pmcid,
key, dupe, check, canon, preimage, url, compare, withdrawn, view,
holdlist), runs diff_biblio.php over it and compares every render byte
for byte. The alphabet holds code points assigned at Unicode 13.0 or
earlier, so Python 3.10's unicodedata, Python 3.13's and ICU classify
them alike (the key form's classes come from the pinned table in any
case; NFC, NFD and the zone's text safety come from the interpreter)."""
