…hon 3.12+)
crosslinked/__init__.py contains a non-raw banner string with backslash art
(\_, \/, \.) and an argparse help string with \{. On Python 3.12+ these
emit SyntaxWarning: invalid escape sequence and are scheduled to become a
SyntaxError in a future release.
Only the backslashes forming an invalid escape are doubled, so the printed
banner and help text are byte-for-byte identical.

What
crosslinked/__init__.pyhas a non raw banner string with backslash ASCII art (\_,\/,\.) and an argparse help string containing\{.Why
On Python 3.12+ these emit
SyntaxWarning: invalid escape sequencewhen CrossLinked is imported, and CPython has scheduled them to become aSyntaxErrorin a future release.Fix
Only the backslashes that form an invalid escape are doubled, so the rendered banner and the
-fhelp text are byte for byte identical. Verified: string-constant multiset unchanged before/after, andpython3 -W error::SyntaxWarning -m py_compile crosslinked/__init__.pyis clean.
