TPC-PY source diff_lint.py (0.1.0), SHA-256 56d54421947ff188; conformed TPS 0.3.0; PROPOSED, not declared (CO-8)

"""diff_lint 0.1.0: the cross-residence differential for tpc_lint 0.1.0.
Random zones built from the tables' own template expansions (random case,
white space of every kind, negations before them, stop characters, hidden
characters inside, letters glued to their edges), credential shapes of
every PL2 pattern with class runs around their bounds, hidden and
White_Space code points, combining marks, Hangul jamo (NFC composes),
CRLF and CR; random tool lists (MCP, Anthropic and OpenAI shapes; known
and unknown member names; credential-shaped and hidden keys; poisoned
descriptions; open-ended names in snake, camel and server-prefixed form;
every JSON escape) and their mutations to invalid JSON or a wrong shape;
invalid UTF-8 given as hex; caps around the zone's length and invalid
caps; counts, counts_of, norm and tokens. Both residences on the same
inputs; 0 differences is the pass. Every code point drawn is assigned
(or unassigned) alike from Unicode 13.0 to 15.1, so the run is valid
under Python 3.10 to 3.13 against PHP's ICU.
Usage: python3 diff_lint.py [seed] [cases]."""
